Abstract:
  Objective  This study aimed to compare the results of the SF-12 and EQ-5D scale in evaluating the quality of life of elderly hypertensive patients in rural areas of Lianyungang City.  Methods  The SF-12 scale and EQ-5D scale were used to evaluate the quality of life of 1 262 elderly hypertensive patients in rural areas of Lianyungang City. T-test, one-way analysis of variance and other statistical methods were used to compare the results, and the physiology of SF-12 was analysed. Pearson correlations amongst the physical component score (PCS), mental component score (MCS), EQ-5D index score and EQ-VAS score were tested.  Results  The 1 262 elderly hypertensive patients surveyed had a total SF-12, PCS, MCS, EQ-5D index and EQ-VAS scores of 70.35±20.57, 66.11±25.21, 74.59±22.55, 0.77±0.10 and 69.22±18.91, respectively. The EQ-5D index score and EQ-VAS score corresponding to different SF-12 score ranges are different (all P < 0.001). PCS and MCS corresponding to different levels in different dimensions were significantly different (all P < 0.001). PCS was strongly correlated with the EQ-5D index score (r=0.632, P < 0.001) and moderately correlated with EQ-VAS score (r=0.442, P < 0.001). Moreover, MCS was moderately correlated with the EQ-5D index score (r=0.467, P < 0.001) and weakly correlated with the EQ-VAS score (r=0.332, P < 0.001).  Conclusion  The SF-12 scale and EQ-5D scale can accurately indicate the quality of life of elderly hypertensive patients, and the results also have a certain correlation. However, EQ-5D has an evident ceiling effect, and SF-12 is more sensitive.

Abstract:
  Objective  This study aimed to observe the mutation characteristics of 23S rRNA gene in children with Mycoplasma pneumoniae (MP) and explore the correlation amongst the mutation, clinical characteristics and drug resistance in children.  Methods  A total of 214 cases of infantile MP with 23S rRNA gene mutation treated with the combination of traditional Chinese and Western medicine in a hospital in Wenzhou from January 2016 to January 2019 were collected and divided into the non-mutated group (36 cases) and mutated group (178 cases). Patient's general information, clinical data and drug susceptibility test results were collected on the basis of medical records to analyse the correlation between 23S rRNA gene mutation with the clinical characteristic and drug resistance of the patients.  Results  A total of 178 cases (83.18%) of 23S rRNA gene mutations were detected. Compared with the non-mutated group, the proportion of severe pneumonia in the mutated group was higher (83.18%); the mean fever time was longer (7.22±2.13) d; the hospital stay was longer (8.30±3.25) d, and the time to normal body temperature was longer (6.45±2.33) d. The differences were statistically significant (all P < 0.05). The drug susceptibility test results showed that the drug resistance rates of azithromycin and roxithromycin in the mutated group (38.20% vs. 25.84%) were significantly higher than those in non-mutated group (13.89% vs. 8.33%), all P < 0.05. Multivariate logistic regression analysis showed that the severity of pneumonia, the time to return to normal body temperature and 23S rRNA gene mutation were independent related factors of MP resistance (OR=1.693, 1.285, 3.338, all P < 0.05).  Conclusion  The mutation of A2603G gene in 23S rRNA is the main type of MP mutation, which has evident resistance to macrolide antibiotics, which can increase the proportion of children with severe pneumonia and significantly prolong the clinical treatment time of children.

Abstract:
  Objective  To investigate the clinical effects of low molecular weight heparin combined with fresh frozen plasma in the treatment of abnormal coagulation functions in critically ill neonates.  Methods  Seventy-two critically ill children with coagulopathy admitted to the neonatal ward of The Second Affiliated Hospital of Bengbu Medical College from February 2019 to August 2020 were selected and divided into an observation group (n=35) and a control group (n=37). Prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (FIB), thrombin time (TT), D-Dimer (D-D) and platelet (PLT) levels were monitored. The control group received conventional treatment, whereas the observation group was administered with low molecular weight heparin and fresh frozen plasma on the basis of conventional treatment. The aforementioned indicators were retested after 72 h of treatment. The clinical efficacy, coagulation function indexes and complication incidence of the two groups were compared.  Results  The effective rate of the observation group was significantly higher than that of the control group after treatment (P < 0.05). No significant difference was observed in the levels of PT, APTT, FIB, TT, D-D and PLT between the two groups before treatment (all P>0.05). After treatment, the PT, APTT, TT and D-D levels of the observation group were significantly lower than those of the control group (all P < 0.05). By contrast, the FIB level of the observation group was significantly higher than that of the control group (P < 0.05). After treatment, the PLT level of the observation group was lower than that of the control group, but the difference was not statistically significant (P>0.05). After treatment, the levels of PT, APTT, TT and D-D in both groups were significantly lower than those before the treatment (all P < 0.05). Furthermore, the level of FIB was significantly higher than that before the treatment (P < 0.05). The levels of PLT in both groups after the treatment were significantly higher than those before thetreatment (P < 0.05). After the treatment, the incidence of intracranial haemorrhage, gastrointestinal hemorrhage and pulmonary hemorrhage in the observation group was lower than that in the control group, but the difference was not statistically significant (all P>0.05).  Conclusion  Early intervention with low molecular weight heparin combined with fresh frozen plasma in the treatment of abnormal coagulation functions in critically ill newborns can improve clinical symptoms and restore coagulation functions. This intervention has good clinical effects.

Abstract:
  Objective  To examine the clinical value of heparin-binding protein (HBP) in the early diagnosis and evaluation of childhood sepsis.  Methods  Total 61 children with sepsis who were hospitalized in the First Affiliated Hospital of Bengbu Medical College from January 2019 to February 2020 were selected and divided into sepsis group (35 cases), severe sepsis group (16 cases) and septic shock group (10 cases) according to the severity of the disease. Meanwhile, 30 children who were hospitalized due to local infection were set as local infection group. The levels of HBP, procalcitonin (PCT), and C-reactive protein (CRP) were compared per group, and the efficacy of each indicator in diagnosing sepsis was compared and analysed.  Results  The overall differences amongst the four groups were statistically significant (F=162.024, 78.944, 10.982, all P < 0.05). The levels of HBP were (19.74±15.2) μg/L, (34.79±14.08) μg/L, (57.42±14.63) μg/L, (191.20±53.28) μg/L; the levels of PCT were (1.33±1.07) ng/mL, (3.38±2.63) ng/mL, (9.93±6.65) ng/mL, (18.13±1.45) ng/mL, respectively, and increased with the aggravation of the disease (all P < 0.05). No statistically significant difference in CRP level existed between the septic shock group [(79.47±18.94) mg/L] and the severe sepsis group [(73.60±26.22) mg/L, P>0.05], and pausal differences between the other groups were statistically significant (all P < 0.05). ROC curve analysis showed that the maximum area under the curve (AUC) was 0.922, sensitivity was 72.13%, and specificity was 96.67% when the three indicators were combined to diagnose sepsis.  Conclusion  Serum HBP has good value in diagnosing childhood sepsis, and the combined detection of the three indices is better than single detection.

Abstract:
  Objective  This study aimed to investigate the effect of medical nutrition therapy (MNT) on blood glucose, body weight and pregnancy outcome of pregnant women with gestational diabetes mellitus (GDM).  Methods  A total of 100 cases of pregnant women with GDM in the first trimester of pregnancy (3 months of pregnancy), who were admitted in our hospital obstetrics department from January to December 2018 for clinical observation, were included in this study. On the basis of the random number table method, the patients were divided into two groups, 50 cases in each group. The control group received routine pregnancy examination, diet guidance and blood glucose control during pregnancy, whereas the observation group received individualised MNT regimen on the basis of routine pregnancy examination. Weight gain during pregnancy (total weight gain, the proportion of abnormal weight gain), blood glucose control results (fasting blood glucose, 2 h blood glucose after breakfast, lunch and dinner, glycosylated haemoglobin), compliance rate (strict diet control, regular blood glucose monitoring, reasonable aerobic exercise and weight control) and the incidence of pregnancy complications related to glucose metabolism (gestational hypertension, dyslipidaemia during pregnancy and delivery of giant newborns) were compared between the two groups.  Results  After 3 months of intervention, the results of blood glucose control in the observation group were better than those in the control group, with significant difference between the two groups (all P>0.05). The total weight gain and abnormal weight gain ratio in the observation group were lower than those in the control group (all P < 0.05). The improvement of compliance rate with strict control of diet and regular monitoring of blood sugar in the control group (70.0%, 76.0%) was better than that in the observation group (86.0%, 90.0%; all P>0.05). The improvement of compliance rate with reasonable aerobic exercise and weight control in the observation group (88.0%, 84.0%) was better than that in the control group (70.0%, 66.0%; all P < 0.05). The incidence of abnormal blood lipid in the delivery group was lower than that in the control group (P < 0.05).  Conclusion  Individualised MNT in early pregnancy can change the compliance rate of women with GDM, control weight gain during pregnancy and reduce the incidence of adverse pregnancy outcomes. Therefore, MNT in early pregnancy has potential clinical application.

Abstract:
  Objective  To investigate the status of perceived role demands, explore the mediating effect of self-efficacy between perceived role demands and self-management among people with type 2 diabetes (T2DM) in China.  Methods  A cross-sectional study was conducted in this study. A total of 210 patients with type 2 diabetes from Jimenli Community Health Service Center in Beijing from May 2016 to June 2016 were surveyed by using perceived role demands scale, self-efficacy scale and siabetes self-management scale for patients with T2DM.  Results  The score of perceived role demands scale ranged from 0 to 9, with median as 0; 66.19% percent of the patients were responsible for household chores, followed by work and child care. There were statistically differences in the perceived role demands of work, household chores and child care between different genders (all P < 0.05). Seventy-eight point five seven percent of patients' self-efficacy scores were in a relatively middle and high level; 65.24% patients' self-efficacy scores were in a middle to low level.Among them, perceived role demands were negatively associated with self-efficacy, and self-efficacy was positively associated with self-management. Perceived role demands were significantly correlated with self-efficacy and self-management (P < 0.05). Self-efficacy had a mediating effect between perceived role demands and self-management, the coefficient was -0.101 (P < 0.001). In addition, self-efficacy mediated the effect of perceived role demands on self-management for females but not males.  Conclusion  There is gender difference in perceived role demands of patients with T2DM. Self-efficacy significantly mediates the relationship between perceived role demands and self-management, especially for females. This finding suggests that for those who are with strong perceived role demands, especially for females with diabetes, Clinicians should consider improving self-efficacy to enhance diabetes self-management behaviors in future interventions.

Abstract:
  Objective  This study aimed to understand the current status of frailty and physical activity of the elderly in Bengbu community, analyse the influencing factors of frailty and provide a basis for further development of frailty prevention and intervention measures to delay the occurrence of frailty.  Methods  A total of 405 cases of elderly people, who were residing in the community of Bengbu City, Anhui Province, from July to December 2019, were conveniently selected as the survey subjects. The general information questionnaire, Tilburg frailty index (TFI) and physical activity scale for the elderly (PASE) were used in this study. The research subjects were asked to fill out the questionnaires for data collection. SPSS 25.0 statistical software was used to perform descriptive statistics, correlation analysis, chi-square test and linear regression analysis on the data.  Results  Amongst the 400 elderly cases, 59 (14.8%) were frail: physical frailty (0.76±1.15) points, mental frailty (1.26±1.03) points and social frailty (1.14±0.85) points. Statistically significant differences in age, gender, marital status, level of education, lifestyle, chronic disease and per capita monthly income (all P < 0.05) were found between the frail group and the non-frail group. The total score range of PASE scale was (91.95±53.12) points. The frailty of the elderly in the community was negatively correlated with physical activity (r=-0.434, P < 0.01). Multiple linear stepwise regression analysis showed that gender, marital status, lifestyle, chronic diseases and physical activity were the influencing factors of frailty (all P < 0.05).  Conclusion  Community medical staff must pay attention to the screening and evaluation of debilitating high-risk groups, particularly women, living alone, widowed or divorced, chronic diseases and elderly people with low physical activity, and timely take corresponding measures to deal with the occurrence of frailty and its adverse outcomes. Patients and their families must be instructed to face frailty, understand disease-related knowledge, reduce the occurrence of adverse health outcomes and improve the quality of life of the elderly.

Abstract:
  Objective  To clarified the expression of IL-17 and IL-22 in tuberculosis heat-resistant antigen (Mtb-Hag) and phosphorylated antigen (HDMAPP) under the polarization state of IL-1β, TGF-β and IL-23 Happening.  Methods  Peripheral blood mononuclear cells (PBMC) were obtained by density gradient centrifugation and cultured in RPMI1640 medium. The experimental group was divided into three groups: Mtb-HAg, HDMAPP, and whole bacterial antigens. Each group was cultured with (IL-1β, TGF-β) for 3 days, rIL-2 for further culture, and IL-23 for 12 days on the 9th day. The control group was divided into three groups: Mtb-HAg, HDMAPP, and whole cell antigen. After 3 days of culture, rIL-2 was added to continue to culture until 12 days. The experimental group and the control group finally expanded into a cell population rich in effector γδ T cells, then the cells were collected and stimulated with PMA/Ionomycin and Monensin for 6 hours, and Tγδ 17 and Tγδ 22 were detected and analyzed. The proportion of cell subpopulations was compared and analyzed.  Results  In all groups, γδ T cells could produce IL-17 and IL-22. The percentage of IL-17 cells produced by γδ T cells in the Mtb-Hag+ck group was significantly higher than that in the Mtb-HAg group, and the HDMAPP+ck group was higher than the HDMAPP group (all P < 0.05). IL-17 was mainly produced by Vδ2 subpopulations, but there was no significant difference in the proportion of IL-22 cells produced by γ δ T cells in different polarization groups.  Conclusion  Under the polarization of IL-1 β, TGF-β and IL-23, the cultured PBMC stimulated by Mtb-Hag and HDMAPP can induce more IL-17 production by γδ T cells, but not IL-22.

Abstract:
  Objective  This study aimed to analyse the main risk factors of contrast agent reflux in four-dimensional ultrasonography of vagina (4D HyCoSy) to provide reference basis for the prevention of contrast agent reflux.  Methods  Women who underwent 4D HyCoSy in our hospital from January 2018 to December 2019 were selected as the study objects. The differences of clinical data and tubal patency between the reflux group (n=248) and non-reflux group (n=410) were compared, and the risk factors of contrast agent reflux were analysed.  Results  Secondary infertility (77.82% vs. 69.51%), history of uterine cavity operation (59.68% vs. 37.07%), adenomyosis (14.52% vs. 9.27%), examination time < 5 days after menstruation (47.18% vs. 38.54%) and endometrial polyp (22.18% vs. 14.88%) were significantly different between the reflux group and non-reflux group (all P < 0.05). Statistically significant differences in the proportion of bilateral fallopian tube obstruction (6.05% vs. 2.44%) and bilateral fallopian tube patency (4.44% vs. 14.63%) were found between the reflux group and non-reflux group (all P < 0.001). The proportion of endometrial polyps (27.92% vs. 12.77%) was significantly different between the myometrium main reflux group and the parathyroid main reflux group (P < 0.05). History of uterine cavity operation, adenomyosis, endometrial polyps and bilateral fallopian tube obstruction were independent risk factors for contrast medium counter current (all P < 0.05).  Conclusion  The incidence of contrast agent reflux was high in 4D HyCoSy, which was related to endometrial injury and bilateral oviduct obstruction.

Abstract:
Hidradenitis suppurativa is a chronic recurrent inflammatory skin disease, which occurs in the skin folds of axillary, inguinal, gluteal and perianal areas. The disease is often seen in young females, which is characterised by inflammatory nodules, abscesses, fistulae and scars. Patients with hidradenitis suppurativa have a long disease history and a reduced quality of life. Although its pathogenesis is still unclear, hidradenitis suppurativa is considered as a result of interactions between genetic factors and other environmental factors. At present, the therapeutic options are limited to antibiotics and other symptom-relieving measures. Aberrant immune responses, including increased cytokines, such as TNF-α, IL-17, IL-12 and IL-23, may play an important role. Considering that the pathogenetic mechanisms are understood, and observations are made when patients with concurrent hidradenitis suppurativa are treated with biological agents, biological treatment has gained considerable attention. Adalimumab, an anti-TNF-α monoclonal antibody, is currently the only biological agent approved by the US FDA based on the results of several clinical trials, which can treat hidradenitis suppurativa, but other biological agents targeting these inflammatory cytokines have also shown good efficacy and safety in the treatment of moderate-to-severe hidradenitis suppurativa. Based on a brief introduction to hidradenitis suppurativa, this review summarises advances in the biological therapy targeting immune factors involved in hidradenitis suppurativa.

Abstract:
Rheumatoid arthritis (RA) is a systemic autoimmune disease that mainly manifests as symmetrically, continuously and erosive polyarthriti multiple arthritis mainly involving small joints such as the proximal interphalangeal joints, metacarpophalangeal joints, and wrist joints of both hands. Elderly patients with RA refers to patients with this disease with an age ed over 60 years. Elderly patients with RA are classified into two clinical subsets, namely, elderly-onset RA (EORA) and younger-onset elderly RA (YORA). The population of elderly with RA is expanding because of the aging of populations and increased life expectancy. EORA seems to have an epidemiological character and a clinical pattern different from that of YORA. A prompt diagnosis of true RA is important to implement early treatment. The diagnosis of EORA from other rheumatological disorders, such as polymyalgia, gouty arthritis and osteoarthritis, which are prevalent in this stratum of the population, are different. The method for diagnosing EORA lacks specificity. In addition, this disease exhibits symptoms similar to EORA, which makes diagnosis more difficult at the early stage. The treatment of EORA aims to achieve the same objectives as in the treatment of YORA, that is, to control clinical manifestations, prevent structural damage, preserve functions and decrease excess mortality. Owing to pharmacokinetics changes, high renal insufficiency, age-related immunosenescence and other risk factors, the management of patients with EORA is challenging. Currently, the drugs used to treat RA include Nonsteroidal anti-inflammatory drug (NSAIDs), glucocorticoid, traditional disease-modifying anti-rheumatic drugs (csDMARD), biological DMARDs (BDMARDs) and targeted synthetic DMARDs (TsDMARDs). Patients with EORA should be carefully monitored because of high risk of adverse events associated with treatment. A tailored approach that aims to achieve clinical remission should be adopted on the basis of disease severity and risk profiles of patients with EORA.

The median score of attitude and behaviour related to needlestick injuries was 4.20 and 4.06, respectively. Working years, departments, risk perception, temperament types and needlestick injury-related behaviour were the main influencing factors (all P < 0.05).  Conclusion  The incidence of needlestick injuries of clinical nurses in third-class-A hospitals in Anhui Province is still at a high level, and the attitude and behaviour related to needlestick injuries are remarkable. The influencing factors of needlestick injuries in clinical nurses include nurses' temperament characteristics, working years, departments, risk perception level and the implementation of needle stick injury prevention measures. Nursing managers should reasonably allocate work tasks according to the characteristics of nurses to reduce the occurrence of needlestick injuries. In the training of needlestick injuries, not only the training of junior clinical nurses, but also the training and education of senior clinical nurses should be paid attention to. In addition to emphasising the risk and harm of needlestick injuries, clinical nurses should also be stressed to correctly understand the risk. After the training, hospital nursing managers should supervise the implementation of needlestick injury preventive measures. Each department should reasonably allocate personnel according to the characteristics of the department.

Abstract:
  Objective  To explore the predictive value of coronary risk index (CRI) for carotid atherosclerosis (CAD) in elderly patients with type 2 diabetes mellitus (T2DM) and provide references for clinical screening of risk for CAD.  Methods  A total of 156 elderly patients with T2DM who were treated in two third-class hospitals in Hefei from September 2019 to December 2019 were selected. On the basis of carotid artery intimal thickening and plaque formation, the patients were divided into non-carotid arteriosclerosis groups: Control group (55 cases), carotid artery intimal thickening group (52 cases) and carotid artery plaque formation group (49 cases). The clinical data of each group were recorded. Data were analysed using SPSS 25.0.  Results  Spearman correlation analysis revealed that the coronary heart disease risk index was positively correlated with carotid artery intima thickness in the elderly patients with T2DM (r=0.158, P=0.049). With the quartile of CRI as the critical value, the coronary heart disease risk index was divided into four intervals (Q1-Q4), and carotid artery intima thickness was analysed via logistic regression analysis. In the Q1-Q3 interval, as the risk of carotid artery intimal thickening increased as CRI increased (OR values for Q1, Q2 and Q3 were 1.000, 1.677 and 5.333, respectively). In the Q4 interval, increased CRI the risk of carotid artery intimal thickening slightly decreased as CRI increased (OR=2.970). The increase in ratio displayed an inverted U-shaped relationship with the risk of carotid artery intimal thickening in the elderly patients with T2DM.  Conclusion  When CRI ranges from 3.59 to 4.14, medical staff should carefully observe if patients are showing clinical signs of microvascular diseases; if the CRI is at an excessively high level for a long time (CRI ≥4.15), the staff should be alerted to the occurrence of occult microvascular diseases. Clinically, the Total Cholesterol/High-Density Lipoprotein Cholesterol (TC/HDL-C) ratio can be included in screening for CAD among elderly patients with T2DM to comprehensively evaluate the risk of CAD in these patients.

On the basis of the 24 h ambulatory blood pressure monitoring results, the patients were divided into the dipper hypertension group (32 cases) and abnormal circadian rhythm (96 cases), and abnormal circadian rhythm was then divided into the non-dipper hypertension group (68 cases) and the reverse dipper hypertension group (28 cases). The intima-media thickness (IMT) and plaque occurrence in the left and right common carotid artery in each group were measured, and the 24-h systolic blood pressure, 24-h diastolic blood pressure, daytime systolic blood pressure, daytime diastolic blood pressure, nocturnal diastolic blood pressure systolic blood pressure of each group were measured, and the general clinical data and relevant biochemical indicators were collected. The clinical indicators of patients in each group were compared.  Results  Nocturnal systolic blood pressure and nocturnal diastolic blood pressure in patients with abnormal circadian rhythm were significantly higher than those in the dipper hypertension group (all P < 0.01). The incidence of plaque in patients with abnormal circadian rhythm was significantly higher than that of the dipper hypertension group (P < 0.01). The IMT values of the left and right sides of patients with abnormal circadian rhythm were significantly higher than those of the dipper hypertension group (all P < 0.01). The nocturnal systolic blood pressure and nocturnal diastolic blood pressure were significantly higher in the anti-arytenoid group than in the non-arytenoid group (all P < 0.01). The detection rate of left common carotid artery plaque and left IMT in the non-dipper hypertension and reverse dipper hypertension groups was significantly higher than those in the right side of the same group (all P < 0.05).  Conclusion  The circadian rhythm of blood pressure in elderly patients with hypertension is significantly different between nocturnal systolic blood pressure and diastolic blood pressure. The circadian rhythm of blood pressure is related to carotid atherosclerosis, and abnormal circadian rhythm of blood pressure causes more damage to target organs. Moreover, abnormal circadian rhythm of blood pressure of non -dipper hypertension and reverse dipper hypertension patients causes more damage to left carotid intima than right.

Abstract:
  Objective  The aim of this study is to compare the effect of propofol and etomidate alone or combination in painless artificial abortion and their influence on cognition of puerperal.  Methods  One hundred and eighty pregnant women scheduled for painless induced abortion in the First Affiliated Hospital of Anhui Medical University from January to April 2019 were randomized assigned into P (propofol), E (etomidate) and EP (etomidate combined with propofol) groups. Before leaving the operating room, the cognitive level was assessed by Montreal cognitive assessment (MoCA). The figures of systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), heart rate (HR), SpO2 were recorded before anesthesia, and after anesthesia induction, during operation and at the end of operation. The injection pain, myoclonus, hypotension, bradycardia, hypoxemia, nausea and vomiting, and other adverse reactions were recorded. The total dose, operation time, recovery time and departure time were recorded.  Results  There were no significant differences in the total score and cognitive domain index scores of MoCA among the three groups (all P>0.05). The P and PE groups obtained relatively satisfactory anesthesia, but the anesthetic effect of 4 cases in the E group was not good. There was no significant difference in SBP, DBP, MAP and HR among groups (all P>0.05), however, there was significant difference in SpO2 among different time points (all P < 0.05). There were interaction effects among groups and time points had interventions on SBP, DBP and MAP. Different interventions and different time points had significant effects on SpO2, and there was interaction (all P < 0.05). The P group had more injection pain than the E and EP and groups (all P < 0.017), the P and EP groups had more frequent hypoxemia as compared with the E group (all P < 0.017), and myoclonus and nausea and vomiting were more frequent in the E group when compared with the P and EP groups.  Conclusion  The propofol and etomidate alone or combination had similar short-term effect on cognition, the combination of propofol and etomidate had the best anesthetic effective in painless abortion, however, etomidate alone had the best safety.

Abstract:
  Objective  This study aimed to investigate the mechanisms of atmospheric fine particulate matter (PM), which enhanced the inflammatory response in cigarette-exposed mice.  Methods  Wild-type and IL-17A knockout (IL-17A-/-) mice were randomly divided into the control group, smoked group, PM group and smoked+PM group according to the random number table method (6-8 mice/group). Mice were exposed to smoke using cigarette smoke exposure device. PM was inhaled by airway instillation, and airway inflammation was observed. After continuous intervention for 3 months, mice were sacrificed to measure airway inflammation. HE was used to detect inflammatory infiltration in lung tissue, and ELISA and RT-PCR were used to detect inflammatory cytokines in lung tissue. Smooth muscle expression was detected by immunohistochemistry, and collagen deposition was observed by Masson staining. In addition, IL-17A-secreting lymphocytes were detected by cell flow cytometry. In in vitro experiments, different concentrations of cigarette smoke extract (CSE) and/or PM were used to stimulate human airway epithelial (HBE) cells, and IL-17A siRNA was used to knock down IL-17A gene in HBE cells. RT-PCR detects the expression of inflammatory factors.  Results  Compared with the control, smoked and PM groups, lung tissue inflammatory factors (CXCL1, TFG-β1, IL-6 and IL-17A), collagen deposition and smooth muscle expression were significantly increased in the smoked+PM group. By contrast, IL-17A-/- mice can alleviate the above-mentioned indicators. Flow cytometry found that PM promoted IL-17A expression by regulating CD4 cells and worsened the inflammatory response induced by smoking. In vitro, CSE or PM intervention in HBE cells can induce the secretion of IL-6 and IL-8, whereas CSE combined with PM can further increase the expression of IL-6 and IL-8. Knockout of IL-17A gene in HBE cells can alleviate the expression of IL-6 and IL-8.  Conclusion  PM can induce the expression of IL-17A and exacerbate the inflammation, collagen deposition and smooth muscle hyperplasia in the lung tissue of cigarette-exposed mice, suggesting that targeted therapy for the IL-17A signalling pathway may be effective in relieving acute exacerbation of COPD caused by PM.

Abstract:
  Objective  This study aimed to investigate the correlation between the miR-15a expression level and progression of bladder cancer and postoperative recurrence in patients with bladder cancer.  Methods  Thirty-two patients diagnosed with bladder cancer who underwent transurethral plasma resection of bladder tumour transurethral resection of bladder tumour (TURBT) in the Department of Urology of the First Affiliated Hospital of Bengbu Medical College from June 2014 to December 2019 were enrolled in this study. Bladder cancer tissue was obtained from the tumour site, whereas paracancerous tissue was obtained from the adjacent normal area. Real-time quantitative polymerase chain reaction was used to detect the expression of miR-15a in bladder cancer tissue samples or paracancerous tissue samples. The Kaplan-Meier method was used to describe the postoperative prognosis curve, and log-rank test was used for comparison amongst groups. The χ2-test test was used to compare the differences in the expression level and general clinical characteristics of miR-15a in bladder cancer tissues and matched paracancerous tissues. Multivariate logistic regression analysis was used to describe the clinicopathological features such as muscular invasion, distant metastasis and tumour grade.  Results  The expression level of miR-15a in bladder cancer tissues was significantly lower than that in adjacent tissues (1.126±0.254 vs 1.450±0.139), and the difference was statistically significant (P < 0.001). In addition, the miR-15a expression level was significantly correlated with muscular invasion (P=0.001), distant metastasis (P=0.005) and tumour grade (P=0.027). Log-rank test showed that patients with down-regulated miR-15a expression had a higher overall recurrence rate, and the difference was statistically significant (P=0.023). Multivariate logistic regression analysis showed that positive distant metastasis, muscular invasion (T2-T4) and tumour grade G3 were independent risk factors for the down-regulation of miR-15a expression.  Conclusion  The expression level of miR-15a may be closely related to the occurrence and development of bladder cancer, and its expression level is significantly correlated with muscular invasion, distant metastasis and tumour grade. The down-regulated expression level of miR-15a may be a biomarker for bladder tumour recurrence.

Abstract:
  Objective  To investigate the factors influencing pulmonary infection after radical resection of lung cancer.  Methods  Eighty-two patients who underwent radical resection of lung cancer in Department of Cardio-thoracic Surgery in Zhejiang Provincial People's Hospital/People's Hospital of Hangzhou Medical College were selected from February 2018 to February 2020. Eighty-two cases of lung cancer, according to whether the lung infection can be divided into pulmonary infection (23 cases) and non-pulmonary infection group (59 cases). The general clinical data of the patients were collected. The factors related to lung cancer that affect postoperative pulmonary infection after radical cure were analysed.  Results  The incidence of postoperative pulmonary infection was 28.05%. Univariate analysis revealed no significant correlation among gender, hypertension, preoperative pulmonary function, lobectomy site, pathological type, pathological stage and postoperative pulmonary infection (all P>0.05). Age (≥60 years old), VAS score of incision (4-10 points), long-term smoking history, combined chronic obstructive pulmonary disease (COPD), diabetes mellitus (DM), operation duratiion (≥3 h), operation method (i.e., traditional thoracotomy), mechanical ventilation time (≥6 h) and indwelling time of thoracic drainage tube (≥4 days) were closely correlated with pulmonary infection (all P < 0.05). Logistic multivariate analysis showed that age (≥60 years old), long operation duration (≥3 h), combined COPD, DM, operation method (traditional thoracotomy), long-term smoking history, VAS score of incision (4-10 points) and long duration of pleural indwelling drainage (≥4 days) were independent influencing factors for postoperative pulmonary infection in patients undergoing radical resection of lung cancer (all P < 0.05).  Conclusion  The incidence of postoperative pulmonary infection is high in lung cancer patients after radical resection pulmonary infection. The risk factors of postoperative pulmonary infection in patients with lung cancer after radical resection are age (≥60 years old), long operation duration (≥3 h), with COPD, with DM (traditional surgery), surgical way, long-term smoking history, VAS score of incision (4-10 points) and long chest drainage timeline (≥4 days). These risk factors should be paid more attentions so as to reduce the incidence of postoperative pulmonary infection.

Abstract:
  Objective  To investigate the prognostic value of systemic immune inflammatory index (SⅡ), neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), and lymphocyte to monocyte ratio (LMR) in patients with cervical cancer of stage ⅠA-ⅡA2 before treatment.  Methods  196 patients with cervical cancer of stage ⅠA2-ⅡA2 who were initially diagnosed in the First Affiliated Hospital of Bengbu Medical College from May 2012 to December 2014 were included. The Cut off values of NLR, PLR, LMR and SⅡ were calculated and divided into high and low value groups.The relationship between the four indexes and clinicopathological parameters in the high and low value groups were observed. The difference in overall survival between high and low value groups were compared. Univariate and multivariate analyses were performed to assess the predictive validity of independent risk factors, and establish a nomogram.  Results  NLR was correlated with histological type and lymphatic vascular stromal infiltration, PLR was correlated with histological type and tumor size, and SⅡ was correlated with histological type, with statistically significant difference respectively (all P < 0.05). The high value group of NLR, PLR and SⅡ and the low value group of LMR had shorter OS, and the difference was statistically significant (all P < 0.05). PLR, SⅡ, histological type and lymph node metastasis were independent risk factors for OS (all P < 0.05). Predictive validity: PLR>SⅡ>lymph node metastasis>the histological type (AUC: 73.2%>71.9%>65.1%>37.0%). The accuracy of the nomogram was high (OS3/OS5 AUC: 90.7%/79.1%).  Conclusion  The value of PLR and SⅡ before treatment can be reliable indicators to predict the prognosis of patients with stage ⅠA2~ⅡA2 cervical cancer.

Abstract:
  Objective  This study aimed to investigate the effect of mangiferin on Staphylococcus aureus-induced pneumonia and on the NF-κB signalling pathway.  Methods  Fifty Balb/c male mice were randomly divided into five groups by the random number method, with 10 mice in each group: control group, S. aureus group and mangiferin (15, 30 and 60 mg/kg) group. After 1 h of S. aureus-induced modelling, the mangiferin group was given intraperitoneal injection of mangiferin. After 12 h, the alveolar lavage fluid and lung tissues of each group were collected. The TNF-α and IL-1β levels of alveolar lavage fluid, wet-to-dry ratio (W/D), activity of pulmonary myeloperoxidase (MPO) and the p65 level of lung tissue were measured.  Results  Compared with the model group, low, middle and high dose of mangiferin could effectively reduce TNF-α, IL-1β, W/D and MPO in a quantitative manner (all P < 0.05). The TNF-α, IL-1β, W/D and MPO of the high-dose mangiferin group were (3.25±0.52) ng/mL, (3.53±0.65) ng/mL, 7.16±0.34 and (3.15±0.61) U/g, respectively, which were significantly lower than those of the model group[(5.28±0.93) ng/mL, (6.63±0.85) ng/mL, 10.55±0.92, (6.74±0.85) U/g, t=6.025, P < 0.001; t=9.161, P < 0.001; t=10.930, P < 0.001; t=10.850, P < 0.001]. Mechanism research showed that mangiferin could effectively down-regulate p-p65 induced by S. aureus.  Conclusion  Mangiferin could improve S. aureus-induced pneumonia in mice by inhibiting the NF-κB signalling pathway.

Abstract:
  Objective  To explore the application of serum albumin, globulin and creatinine to predict the severity of Guillain-Barré syndrome (GBS).  Methods  A total of 106 patients with GBS treated in the Department of Neurology, the first affiliated Hospital of Bengbu Medical College from June 2016 to May 2020 were selected. Hughes functional score was used to compare the differences of albumin, globulin and creatinine between the two groups. Spearman correlation analysis was used to analyze the correlation between the levels of albumin, globulin, creatinine and the severity of disease in patients with GBS. The globulin and creatinine related to the severity of the disease were selected and analyzed by ROC curve.  Results  The levels of serum albumin (40.12±4.43) g/L and creatinine (63.47±11.64) μmol/L in GBS patients were lower than those in healthy controls [(47.42±4.14) g/L, (83.96±31.00) μmol/L, all P < 0.05], while the levels of globulin (29.94±5.68) g/L were higher than those in healthy controls (24.58±6.17) g/L, P < 0.05. The levels of globulin and creatinine in patients with GBS were correlated with the severity of the disease (r=0.353, P < 0.001; r=0.323, P < 0.001). The ROC curve showed that the area under the curve of globulin predicting GBS severe group was 0.699 (95% CI: 0.602-0.784). The area under the curve predicted by creatinine in GBS severe group was 0.671 (95% CI: 0.573-0.760).  Conclusion  The level of globulin in patients with GBS is positively correlated with the severity of the disease, while the level of creatinine is negatively correlated with the severity of the disease. Globulin and creatinine have certain value in evaluating the severity of GBS.

Abstract:
  Objective  This study aimed to explore the gender-related factors and clinical characteristics of elderly patients with heart failure and preserved ejection fraction (HFpEF) and compare the safety of enhanced external counterpulsation (EECP) in the treatment of elderly patients with HFpEF of different genders.  Methods  A total of 200 elderly patients (≥65 years old) who received EECP treatment at the Second Affiliated Hospital of Zhengzhou University from January 2019 to January 2020 and were diagnosed with HFpEF were divided into the male group (n=88) and female group (n=112) according to gender. General clinical data (age, BMI, smoking history and past history), inspection data [NYHA cardiac function grade, renal function, left ventricular ejection fraction (LVEF) and Brain Natriuretic Peptide], BNP were recorded, and the adverse reactions of the elderly HFpEF patients of different gender were compared after EECP treatment.  Results  The number of elderly women with HFpEF was significantly higher than that of men (56% and 44%, P < 0.05), and the age of disease, BMI and LVEF were greater than that of men (all P < 0.05). There are more patients in the NYHA heart function class Ⅲ and Ⅳ in the female group than in the male group; the number of elderly male HFpEF patients with smoking history was greater than that of females (P < 0.05), and there are more patients in the NYHA cardiac function classification of grade Ⅰ and Ⅱ in the male group than in the female group. Analysis of related factors showed that obesity, atrial fibrillation, hypertension and LVEF have a strong correlation with the female group (all P < 0.05); smoking history and hyperlipidaemia have a strong correlation with the male group (P < 0.05). The incidence of adverse reactions in different gender groups of EECP treatment for HFpEF was not statistically significant (7.95% vs. 9.82%, P > 0.05).  Conclusion  Gender differences in the relevant factors of elderly HFpEF patients are found, and the clinical characteristics of elderly female HFpEF patients are unique, but EECP has the same safety for elderly HFpEF patients of different gender.

Abstract:
  Objective  To investigate the expression of human B cell activating factor (BAFF) and interleukin-21 (IL-21) in the plasma of patients with Hashimoto's thyroiditis (HT) and explore their roles in the pathogenesis of HT.  Methods  Patients with HT in the Endocrinology Clinic of The First Affiliated Hospital of Bengbu Medical College from December 2019 to June 2020 were selected as the observation group (HT group, n= 82). According to thyroid functions, the HT group was further divided into an NHT group (normal thyroid function, n= 39) and an SHT group (hypothyroidism or subclinical hypothyroidism, n=43). A total of 51 patients (NC group) who visited the hospital for consultation during the same period were designated as the control group. Peripheral venous blood plasma was collected. BAFF and IL-21 were tested via enzyme-linked immunosorbent assay(ELISA). Thyroid function, thyroid microsomal antibody (TMAB) and thyroglobulin antibody (TGAB) were detected via chemiluminescence immunoassay. Data were analysed using SPSS 24.0.  Results  The levels of BAFF and IL-21 in the plasma of the HT group were significantly higher than those of the NC group (all P < 0.05). The levels of BAFF in the SHT group was significantly higher than that in the NHT group (P < 0.05). The plasma levels of BAFF in the patients with HT were positively correlated with TGAB and TMAB (r=0.444 and 0.401, respectively; all P < 0.05). Similarly, IL-21 was positively correlated with TGAB and TMAB (r=0.451 and 0.451, respectively; all P < 0.05). A positive correlation was observed between BAFF and IL-21 (r=0.324, P < 0.05). By contrast, a negative correlation was found between BAFF and total T4(TT4, r=-0.214, P < 0.05). The combined diagnosis of HT with BAFF and IL-21 (AUC=0.896) was more valuable than that of BAFF (AUC=0.862) and IL-21 (AUC=0.809) alone.  Conclusion  BAFF combined with IL-21 has a certain value in the diagnosis of HT. BAFF and IL-21 play an important role in the occurrence and development of HT. Moreover, they participate in the maturation, proliferation and differentiation of B cells. Finally, they participate jointly in the production of TGAB and TMAR.

Abstract:
  Objective  To explore the immunophenotype and clinical characteristics of patients with acute myeloid leukaemia (AML) with fms-like tyrosine kinase 3-internal tandem replication (FLT3-ITD) mutation.  Methods  A total of 103 patients with AML (excluding the M3 type), including 24 patients with FLT3-ITD+ (positive group) and 79 patients with FLT3-ITD- (negative group), who were initially diagnosed in the haematology department of the First Affiliated Hospital of Bengbu Medical College from December 2016 to December 2018 were enrolled in this study. The clinical haematological characteristics and immunophenotypes of the two groups were retrospectively studied. The patients in both groups were followed up, and the overall reaction rate (OR), progress-free survival (PFS) and overall survival (OS) were calculated.  Results  The expression rates of CD33, CD7, CD56 and CD38 in the FLT3-ITD+group were significantly higher than those in the FLT3-ITD- group (all P < 0.05). By contrast, the expression rates of CD13 and CD34 were low (all P < 0.05). White blood cell count, haemoglobin count, bone marrow leukaemia cells and mutation rate of combined NPM1 in the FLT3-ITD+ group were higher than those in the FLT3-ITD- group (all P < 0.05). after the treatment the Objective response rate in the FLT3-ITD- group (78.5%) was significantly higher than that in the FLT3-ITD+ group (33.3%), and the difference was statistically significant (P < 0.001). The median OS and PFS in the FLT3-ITD+ group were 9.5 and 9 months, respectively, and those in the FLT3-ITD- group were 17 and 16 months, respectively. The OS and PFS of the FLT3-ITD- group were longer than those of the FLT3-ITD+ group (P < 0.05).  Conclusion  Patients with AML with FLT3-ITD+ have abnormal expression of leukaemia cell antigen, high peripheral blood leukocytes, abundant haemoglobin and bone marrow primordial cells, are prone to NPM1 mutation, have shortened PFS, OS and reduced the response rate. Hence, the treatment effect and prognosis of these patients are poor.

Abstract:
  Objective  This study aimed to investigate the effects of infusion under Flotrac/Vigileo monitoring on postoperative recovery and inflammatory response in patients undergoing laparoscopic radical cystectomy for bladder cancer.  Methods  A total of 160 patients undergoing laparoscopic radical cystectomy for bladder cancer in Taizhou Central Hospital from January 2019 to December 2019 were selected and divided into group A and group B by the random number method, with 80 patients in each group. Group A was given liquid infusion based on "4/2/1" rule for Ⅳ, and group B was given liquid infusion according to Flotrac/Vigileo monitoring results. Peripheral venous blood was collected before surgery, 1 day after surgery, 3 days after surgery and 7 days after surgery. Serum samples were separated. Serum levels of tumour necrosis factor-α (TNF-α), interleukin-2 (IL-2) and IL-6 were determined by double-antibody ELISA.  Results  No significant differences in anaesthesia time, operation duration, postoperative recovering time, total fluid volume, blood loss and urine volume, haemodynamics, complications, length of hospital stay, bladder volume, maximum urine flow rate and bladder pressure were found between the two groups (all P > 0.05). The amount of colloid Ⅳ solution in group B [(1 291.45±224.83) mL] was higher than that in group A (P < 0.05), and the amount of crystalloid Ⅳ solutions in group B [(992.13±234.15) mL] was lower than that in group A (P < 0.05). The anal exhaust time of group B [(61.35±14.16) h], time to post-operative ambulation [(6.34±1.42) h] and time of resuming feeding [(3.51±1.07) h] were all shorter than those of group A (all P < 0.05). Compared with preoperation, the serum levels of TNF-α and IL-6 increased and IL-2 decreased in the two groups at 1 and 3 days after operation (P < 0.05). The serum levels of TNF-α and IL-6 in group B were higher than those in group A, while the serum level of IL-2 was lower than that in group A (P < 0.05).  Conclusion  Infusion under Flotrac/Vigileo monitoring can promote postoperative recovery and inhibit perioperative inflammatory response in patients undergoing radical laparoscopic radical bladder cancer surgery.

Abstract:
  Objective  To compare the predictive value of inferior vena cava ultrasound indicators and central venous pressure (CVP) as predictors of fluid of responsiveness in patients who experienced septic shock.  Methods  Twenty-seven patients who experienced septic shock were enrolled in the study. The diameter of inferior vena cava (d-IVC) and its variation with respiration (v-IVC), CVP measured by bedside ultrasound, arterial blood lactate level and cardiac index (CI) were collected at hospitalisation and after resuscitation. The fluid resuscitation was performed as follows: All patients were administered with 7 mL/kg lactated Ringer's solution (ideal body weight) within 20 min. Fluid responsiveness was defined as ΔCI≥15% after resuscitation (responding group or R group, n=19; the rest was classified as nonresponding group or NR group, n=8). The accuracy of predicting volume responsiveness was evaluated by plotting the receiver operating characteristic (ROC) curve on the basis of the measured indicators before resuscitation.  Results  Compared with the NR group, the R group had a low d-IVCmin, d-IVCmax and a significantly high v-IVC before resuscitation (P < 0.05). However, no significant difference was observed in lactate level of arterial blood, CVP before resuscitation (P > 0.05). The optimal cut-off value of v-IVC was 17.65%. The sensitivity and specificity of the predictive value of volume responsiveness in patient who experienced septic shock were 100.0% and 87.5%, respectively. The area under the ROC curve of v-IVC for predicting volume responsiveness was 0.924 (95% CI: 0.781-1.000).  Conclusion  The predictive value of v-IVC in the volume responsiveness of patients who experienced septic shock is high, and the predictive value is higher when v-IVC >17.65%.

Abstract:
  Objective  To investigate the expression and correlation of serum sulfonylurea receptor 1 (SUR1) in middle-aged and elderly patients with aneurysmal subarachnoid haemorrhage (aSAH).  Methods  Ninety-one patients suffering from aSAH admitted to Ningbo Sixth Hospital from July 2015 to May 2019 were selected as the observation objects. The expression of SUR1 in serum before operation was detected via fluorescence real-time quantitative polymerase chain reaction. According to the median expression of Sulfonylurea receptor 1(SUR1) in serum before operation, the patients were divided into low SUR1 expression group (n=46) and high SUR1 expression group (n=45). Before operation, the degree of nerve defect in the patients with aSAH was evaluated using the national institutes of health stroke scale (NIHSS) score. At 6 months after operation, prognosis was assessed using the Glasgow Outcome Scale, and the patients were divided into good prognosis group (n=77) and poor prognosis group (n=14). The expression of SUR1 before operation was compared between the two groups. The correlation between SUR1 expression and NIHSS score was evaluated via Spearman correlation analysis. The prognostic factors of the patients with aSAH were analysed via Cox model.  Results  The proportion of patients with hypertension history, with diabetes history, preoperative NIHSS score and operative timing in the good prognosis group were lower than those in the poor prognosis group (all P < 0.05). The expression of serum SUR1 in patients with aSAH in the poor prognosis group was higher than that in the good prognosis group (P < 0.05). Spearman correlation analysis revealed a positive correlation between serum SUR1 expression and NIHSS score in the patients with aSAH (P < 0.05). The Results of Cox regression model showed that age of >60 years, history of hypertension, history of diabetes, NIHSS score ≥15, 3-7 d of operation timing and SUR1 overexpression were all independent risk factors for the prognosis of patients with aSAH (all P < 0.05).  Conclusion  SUR1 may be involved in the development and progression of aSAH in the middle-aged and the elderly, and may become a serological index for the assessment of aSAH and treatment target.

Abstract:
  Objective  To compare the clinical value of small bowel capsule endoscopy (SBCE) and magnetically controlled capsule endoscopy (MCE) in the diagnosis of digestive tract diseases.  Methods  A total of 154 patients who underwent capsule endoscopy in the Department of Gastroenterology of our hospital were selected, and the clinical data were analyzed retrospectively. The feasibility and detection of diseases of capsule endoscopy were analyzed, and the differences of small intestinal diseases among SBCE patients with different gender, age and main clinical symptoms were analyzed.  Results  All the patients who underwent capsule endoscopy successfully completed the examination of the main parts of digestive tract and collected images, which were finally discharged smoothly within 2 weeks. Only one elderly patient developed adverse reactions during the magnetic capsule endoscopy and then self-relieved. The overall detection rate of digestive tract diseases in the MCE group was 96.6% (85/88) higher than that in the SBCE group 78.8% (52/66), and the difference was statistically significant (P < 0.05). The detection rate of small intestinal diseases in SBCE group was 71.2% (47/66) higher than that in MCE group 21.6% (19/88), and the difference was statistically significant (P < 0.05). The detection rate of intestinal lesions in SBCE group with gastrointestinal bleeding was 95.7% (22/23) higher than that in other symptom groups, and the difference was statistically significant (P < 0.05). In MCE group, the detection rate of gastric lesions was 90.9% (80/88), while that of small intestine lesions was 21.6% (19/88). And erosive lesions were 42.1% (8/19) and ulcerative lesions were 31.6% (6/19) in small intestine lesions.  Conclusion  SBCE and MCE are both important ways to screen digestive tract diseases.SBCE has high diagnostic value for small intestinal diseases, especially for small intestinal bleeding. MCE not only has a high detection rate for stomach diseases, but also has certain significance in diagnosis of small intestine diseases.

Abstract:
  Objective  To observe the clinical efficacy and side effect of Jiedu Quyu Zishen Recipe prescription on hormone therapy for systemic lupus erythematosus (SLE).  Methods  A total of 110 patients with moderate systemic lupus erythematosus were divided into control group (n=55) and study group (n=55) by random number table. Patients in the control group were treated with prednisone acetate, and patients in the study group were given Jiedu Quyu Zishen Recipe supplemented with prednisone acetate. The serum levels of antinuclear antibody (ANA), anti-double stranded DNA (anti-dsDNA), IgA and IgG of the two groups were compared before and after treatment. The SLE disease activity index (SLEDAI) score was conducted to detect the urine protein level, evaluate the clinical efficacy of systemic lupus erythematosus after treatment, and observe the adverse drug reactions during treatment.  Results  After treatment, the levels of ANA, anti-dsDNA, IgA and IgG in the study group [(1.74±0.18) mg/mL, (0.99±0.10) mg/mL, (1.45±0.12) mg/mL and (8.57±0.74) mg/mL] were significantly lower than those in the control group [(2.15±0.21) mg/mL, (1.32±0.16) mg/mL, (1.78±0.14) mg/mL and (11.57±1.02) mg/mL], P < 0.05. After treatment, SLEDAI score and urine protein content at 24 h [(4.57±0.36) points and (0.67±0.06) g] in the study group were significantly lower than those in the control group [(5.18±0.49) points and (0.93±0.08) g], P < 0.05. The overall response rate of systemic lupus erythematosus in the study group (96.67%) was significantly higher than that in the control group (83.33%), P=0.015. The overall incidence of adverse drug reactions in the study group (11.63%) was significantly lower than that in the control group (33.33%), P=0.004.  Conclusion  Jiedu Quyu Zishen Recipe can assist prednisone acetate in the treatment of systemic lupus erythematosus. On the basis of reducing the maintenance dose of prednisone acetate, it can effectively relieve clinical symptoms, improve curative effect, and reduce adverse reactions of hormone drugs. It has the effect of enhancing and reducing toxicity, and is worthy of clinical promotion.

Abstract:
  Objective  To observe the adverse effects of low hypotriiodothyronine (T3) syndrome on premature infants.  Methods  Thirty premature infants hospitalised in the neonatal ward of The First Affiliated Hospital of Bengbu Medical College from January to 2019 to December 2019 were selected. About 4 to 7 days and 4 weeks after birth, 2 mL of fasting venous blood was collected from the infants. Serum thyroid-stimulating hormone (TSH), free triiodothyronine (FT3) and triiodothyronine (T3) were determined via electrochemiluminescence. According to the diagnostic criteria, premature infants diagnosed with low T3 were taken as the observation group (n=30), whereas premature infants with normal thyroid functions at the same gestational age were taken as the control group (n=30). No statistical difference was observed in the general conditions of the two groups (P > 0.05), both group were given with the same basic supportive treatment. Differences in the duration of jaundice, feeding intolerance, hospitalisation days, days of birth weight recovery and neonatal behavior neurological assessment (NBNA)test scores at 40 weeks of gestational age were observed between the two groups.  Results  Between the two groups, T3 levels at 4 to 7 days after birth (t=-19.042, P < 0.001) and FT3 levels at 4 weeks after birth (t=-22.041, P < 0.001) were statistically significant. At 4 weeks after birth, T3 levels (t=-1.933, P=0.059) and FT3 levels (t=-1.622, P=0.110) were not statistically significant. The differences in jaundice duration (t=2.759, P=0.008), feeding intolerance (χ2=8.531, P=0.003), hospitalisation days (t=6.471, P < 0.001) and birth weight recovery days (t=6.584, P < 0.001) were statistically significant between the two groups. However, no statistically significant difference (t=-1.842, P=0.071) was observed in NBNA scores between the two groups at the correct gestational age of 40 weeks.  Conclusion  Children with a low T3 syndrome have longer jaundice durations, hospitalisation days and weight recovery times, as well as a higher incidence of feeding intolerance, than children with normal thyroid functions. Nevertheless, their short-term neurodevelopment was not significantly influenced.
