Abstract:
Objective Through the preliminary investigation and literature search, it is found that the community doctors in Xian and even the national specialists have insufficient understanding of the diagnosis and treatment of the upper respiratory tract infections (URTIs) in child, which leads to the blindness of therapy such as repeated medication, improper combination of drugs and excessive use of antiviral and antibiotics, etc. All of these lead to the result that some community hospitals were not able to fully assume the responsibility for the first diagnosis of URTIs in child. The current pediatric diagnosis and treatment process for URTIs is aimed at pediatric specialists; there are no complete rules and procedures suitable for general practitioner (GP). In order to enhance the ability of general practitioners, there is an urgent need for the diagnosis and treatment of URTIs in children. The aim of this paper is to summarize the diagnosis, treatment and management process of URTIs in children which could be applicable in community health centers in China. Methods Seven items of the latest guidelines, norms or expert consensus about the diagnosis and therapy of URTIs in children both from domestic areas and foreign countries were involved in. Upon general practitioner jobs, all of them were compared and analyzed according to the following four-dimension, such as diagnostic criteria, differential diagnosis, treatment principles and rational administration, etc. Results The process for diagnosis, treatment and management of URTIs in children suitable for General Physicians in community health centers were formed. Conclusion Following this process, an overall assessment of URTIs in children should be given by the first visited GPs, appropriated therapy could be provided depending on the different varieties, severity and course of URTIs. For the patients in acute period, the priority of therapy should be given to symptomatic treatment on the basis of clinical observation. Antibiotics can only be used if there is at least a proper indication for it. Children with influenza should accept antiviral drugs as early as possible.

Abstract:
Objective To investigate the situation of serotype distribution of Streptococcus pneumoniae (S. pneumoniae) isolated from Chinese hospitalized children and to evaluate the value of pneumococcal conjugate vaccine in the prevention of S. pneumoniae infection. Methods S. pneumoniae strains isolated from clinical specimens of 751 children hospitalized in Beijing Children's Hospital between March, 2013 and December, 2017 were studied. The serum type was detected by capsule swelling experiment. Results A total of 751 isolates of S. pneumoniae were collected, including 684 non-invasive strains and 67 invasive strains. The non-invasive strains were mainly isolated from respiratory secretions (52.3%) and bronchoalveolar lavage fluid (44.4%). The invasive strains were mainly isolated from blood (50.7%), pleural effusion (25.4%) and cerebrospinal fluid (23.9%). The common serotypes of the 751 strains were 19F (37.0%), 19A (14.2%), 23F (9.5%), 14 (7.9%), 6A (7.7%) and 6B (5.2%), accounting for 81.5%. The coverage rates of PCV10, PCV13 and PPV23 were 61.5%, 84.3% and 82.6%, respectively. The most common serotypes of non-invasive strains were 19F (37.3%), 19A (13.5%), 23F (9.5%), 6A (8.0%), 14 (7.0%) and 6B (5.6%). The coverage rates of PCV10 and PCV13 were 60.8% and 83.0%, respectively. The most common serotypes of invasive strains were 19F (34.3%), 19A (22.4%), 14 (16.4%), 23F (9.0%), 6A (4.5%), 9V (3.0%) and 1 (3.0%). The coverage rates of PCV10 and PCV13 were 68.7% and 95.5%, respectively. Conclusion Serotype 19F, 19A, 23F, 14, 6A and 6B, all of which were included in PCV13, were the common types among the pneumococcal strains isolated from hospitalized children in Beijing Children's Hospital. The coverage rate of PCV13 is more than 80%, and the coverage rate is higher in the invasive infection strains, indicating the promotion of PCV13 can prevent the overwhelming majority of S. pneumoniae infection.

Abstract:
Objective To analyze the status of diagnosis of lung cancer in tertiary hospitals in our province, and provide basis for the optimization of diagnostic methods for patients with lung cancer. Methods A lung cancer diagnostic status questionnaire was designed by the expert group of lung cancer quality control center in our province. In July, 2016, the questionnaire survey of lung cancer diagnosis was conducted in 57 three level hospitals in our province. The valid data were collected and analyzed statistically. Results Among different diagnostic methods, bronchoscopy occupied the highest selection rate (20.0%, 163/816) for suspicious central lung cancer. CT- or ultrasound- guided percutaneously transthoracic lung biopsy taken up the highest selection rate for the peripheral pulmonary lesions (18.0%, 142/790). Focusing on the selection rate of a given diagnostic method for different types of lung cancer, bronchoscopy (χ²=59.305, P<0.001) and repeated sputum cytology (χ²=11.595, P=0.001) were commonly used for central lung cancer, that obviously surpassed peripheral pulmonary lesions, however, the selection rate of CT-guided or ultrasound-guided percutaneously transthoracic lung biopsy (χ²=14.477, P<0.001) and direct surgery (χ²=25.014, P<0.001) in central lung cancer was significantly higher than that in peripheral pulmonary lesions. Among the different levels of hospitals, EBUS or TBNA (χ²=9.421, P=0.002) and direct surgery (χ²=4.195, P=0.041) were most commonly used in provincial hospital, the selection rate was significantly more than that of municipal hospitals; the selection rate of R-EBUS guided bronchoscopy (χ²=5.854, P=0.016) in tertiary hospitals was significantly more than that of the three B hospitals. Conclusion Conventional bronchoscopy and percutaneous lung biopsy are the main means for the diagnosis of lung cancer in our province, but new technologies are less developed. Provincial hospitals and tertiary hospitals are superior to municipal hospitals and three B hospitals in the diagnosis level and concept of lung cancer.

Abstract:
Objective To establish the radiolabeling method of exendin-4, an glucagon-like peptide 1 (GLP-1) receptor agonist, with ¹³¹I and observe the biodistribution of ¹³¹I-exend in-4 in normal mice. Methods Radiolabeling of exendin-4 with ¹³¹I was performed by chloramine-T method. The labeling ratio and radiochemical purity were determined using paper chromatography and TLC. The octanol-water partition coefficient and stability in vitro in saline and normal human serum of labeled polypeptide were also determined. The biodistribution of ¹³¹I-exendin-4 in normal mice were measured at 1, 3, 6, 12, 24 h after intravenous injection. SPECT was performed in 3 male mice after injection of ¹³¹I-exendin-4 to observe the dynamic distribution of the labeled exendin-4. Results The labeling yield of ¹³¹I-exendin-4 was more than 85%. The ¹³¹I-exendin-4 had good stability in saline and normal human serum. The octanol-water partiton coefficient lg P=-1.002. The biodistribution in mice showed that ¹³¹I-exendin-4 had rapid blood clearing, and the radioactivity in kidney was obviously higher than that of other organs as indicated by their uptake of (51.54±13.51)%ID/g at 1 h and (11.61±0.94)%ID/g at 12 h, respectively. Organs such as stomach, lung, intestine and bone had transient radioactive uptake, and then after 3 h the radioactivity in those organs rapidly decreased. The radioactivity in other organs always kept at a low level. Conclusion ¹³¹I-exendin-4 can be easily labeled with a high labeling ratio with stability in vitro. It has good distribution characteristics in vivo, and is cleared mainly by renal excretion due to its hydrosolubility.

Abstract:
Objective To investigate the clinical effect of breast-conserving surgery and modified radical mastectomy in the treatment of early breast cancer. Methods The clinical data of 88 patients with early breast cancer from January, 2012 to June, 2016 in our hospital were analyzed retrospectively. Forty-four patients in the breast-conserving group received the breast-conserving surgery, while 44 patients in the modified radical group received the modified radical mastectomy. The operative time, intraoperative blood loss, hospitalization time, postoperative period cosmetic effect, recurrence rate, metastasis rate and survival rate were compared between the two groups in order to assess the efficacy of two surgical methods. Results ①The operation time and hospitalization time of the patients in the breast-conserving group were significantly shorter than those in the modified radical group, and the intraoperative blood loss was significantly less than that of the modified radical group. The difference between the two groups in the operation time, intraoperative blood loss and hospitalization time was statistically significant. ②At the end of follow-up, 1 case of recurrence occurred in the breast-conserving group, 1 case of metastasis, no death occurred. There were 2 cases of metastasis and 1 case of death in the modified radical group, and no local recurrence. There was no significant difference in recurrence rate, metastasis rate and survival rate between the two groups. ③ After the decision, 39 cases in the breast conserving group were excellent, 3 cases were general, 2 cases were poor. The excellent rate of breast-conserving patients was 88.6%. The cosmetic effect in the modified radical group was judged as poor because of the implementation of the whole mastectomy surgery, and the postoperative cosmetic effect of breast-conserving group was significantly better than that in the modified radical group, the difference was statistically significant. Conclusion In the treatment of early breast cancer, breast-conserving surgery is with the advantage of short operation time, less intraoperative bleeding, short hospital stay, good cosmetic effect and rapid postoperative recovery when compared with the modified radical surgery. There is no significant difference in the local recurrence rate, distant metastasis rate and survival rate between the two groups, which is worthy of clinical promotion.

Abstract:
Objective To observe the clinical efficacy of Omega-3 polyunsaturated fatty acids (omega-3PUFAs) in the treatment of ulcerative colitis (UC) and its influence on peripheral blood Th17/Treg cell balance and the levels of cytokines IL-10 and IL-17. Methods A prospective randomized controlled study was conducted. Fifty patients with UC were enrolled from Lishui Central Hospital in Zhejiang province from January, 2014 to December, 2016. The time and place of the study were added. The patients were divided into 2 groups by random number table. Twenty-five cases in Control group, mesalazine 1 g 4 times a day orally; 25 cases in Observation group, mesalazine 1 g 4 times a day orally and ω3-PUFAs 100 ml 1 times a day intravenous drip. Other nonspecific treatment measures were the same in the two groups, and the course of treatment was one weeks. The expressions of serum IL-10 and IL-17 were detected by ELISA, and the proportion of Treg cells and Th17 cells in peripheral blood was detected by flow cytometry. The clinical effective rates of the two groups were compared. The levels of serum IL-10 and IL-17, the ratio of Treg cells and Th17 cells in peripheral blood before and after the treatment were compared. Results There was no significant difference between the two groups in age, sex, course of disease and severity of the disease (P>0.05). The total effective rate of clinical symptom improvement in the observation group (88%) was obviously better than that of the control group (68%), the difference was statistically significant (P<0.05). Compared with the same group before treatment, the proportion of Treg cells and IL-10 levels in peripheral blood of both groups increased significantly, while the proportion of Th17 cells and the level of IL-17 were significantly decreased, the difference was statistically significant (P<0.05). Compared with Control group, the proportion of Treg cells and IL-10 levels in peripheral blood of the observation group increased more significantly, but the proportion of Th17 cells and the level of IL-17 decreased more significantly, the difference was statistically significant (P<0.05). Conclusion ω-3 PUFAs has good clinical efficacy in the treatment of UC, and its mechanism may be related to regulating the balance of Treg/Th17 and alleviating the inflammatory reaction of UC.

Abstract:
Objective To find out the awareness of knowledge and medical burden of hepatitis C on patients with chronic hepatitis C in hospital. Methods Patients with chronic hepatitis C from 4 hospitals in Beijing, Henan, Jilin and Liaoning province were surveyed by questionnaires,from July to October 2016, to investigate their demographic characteristics, awareness of hepatitis C, as well as medical burdens of hepatitis C. Results A total of 359 cases, including 171 males (47.6%), and 188 females (52.4%), were under investigation, with the average age of (55.1±11.9) years. Among them, only 7.5% correctly answered all questions, 11.1% did not know anything about hepatitis C knowledge, and only 17.8% of the participants answered correctly to all five questions about transmission route of hepatitis C. The correct rate of hepatitis C knowledge in different regions, sex, age, educational level and national chronic hepatitis C patients was different, and the difference was statistically significant, but the difference between marital status, occupation and family per capita monthly income was not statistically significant. And 186(51.8%) participated in the town health insurance and 126(35.1%) participated in the new rural cooperative medical system. For 176(49.0%), the total cost of hepatitis C treatment was more than 30 000 yuan. There were significant differences in the total cost of treatment in different areas and different types of medical insurance. The treatment effect of hepatitis C has no improvement in 120(33.4%), general improvement in 165(46.0%), obvious improvement in 62(17.3%), and only 12(3.3%) recovery. Conclusion The patients of hepatitis C were barely aware of knowledge of hepatitis C. More efforts for hepatitis C education are wanted. There is less cost for treatment in economically disadvantaged areas. New rural cooperative patients with low proportion of hepatitis C reimbursement, and the cost of treatment is high. We should increase the support for farmers and other low income people, and it may help reduce the medical burden.

Abstract:
Objective To investigate the value of dynamic enhanced magnetic resonance imaging (DCE-MRI) quantitative perfusion parameters in differentiate uterine fibroids subtypes and analyze whether there is correlations between the perfusion parameters and micro vascular density (MVD), vascular endothelial growth factor (VEGF), and Ki-67. Methods Sixty-three patients underwent hysteromyoma resection between October, 2015 and September, 2016 were divided pathologically in three groups:classical(29 cases), cellular(12 cases)and degenerative (22 cases). All patients performed DCE-MRI preoperative, double-chamber model Extended-tofts was used to calculate the parameters (K^trans, K_ep, V_e, V_p) and depict the parameters map. Immune-histochemical methods were used to measure the expression of MVD, VEGF, and Ki-67. The parameters, MVD, VEGF and Ki-67 were compared in the three groups. The correlations between parameters and immune-histochemical fractions were also explored. Results The value of K^trans, K_ep and Vp were higher in the cellular group than in the classical group and the degenerated group (P<0.05); K^trans, K_ep, V_e and V_p were positively associated with MVD(r=0.770, r=0.524, r=0.276, r=0.472; P<0.05). K^trans, K_ep, V_p were positively as sociated with Ki-67(r=0.637, r=0.421, r=0.439; P<0.05). While Ki-67 and MVD also showed apositive correlation (r=0.681, P<0.001), there were no correlation between quantitative perfusion indexes and VEGF. Conclusion Quantitative perfusion parameters derived DCE-MRI contribute to differentiation varies pathological subtypes of uterine fibroids, and these parameters can be used as predictors to evaluate uterine fibroids microvascular and cell proliferative activity.

Abstract:
Objective To explore the CT and MRI findings of uncommon type of chondrosarcoma (uCHS), and improve the diagnosis and treatment of uncommon type of chondrosarcoma. Methods CT and MRI imaging features of 14 cases of uCHS confirmed by surgery or needle biopsy and pathological examination were retrospectively analyzed. The imaging data included plain CT (n=6) and contrast enhanced CT (n=4), as well as plain and contrast enhanced MRI (n=9). Results Total 14 lesions were respectively located in posterior peritoneum, anterior mediastinum, posterior mediastinum, left thigh, atlas, left ischium, left pubis, right parasellar region, right petrosum, right cotyle, thoracic vertebras, left parietal bone, left rib, left scapula respectively. ①Myxoid chondrosarcoma in 5 cases:Mild expansive or osteolytic bone destruction accompanies extraosseous lobulated or irregular soft tissue masses with few calcifications were showed on CT imaging. MRI scanning showed obviously heterogeneous long T₁ long T₂ signal and heterogeneous enhancement after contrast administration. One case associated hemorrhage. ②Mesenchymal chondrosarcoma in 4 cases:All of the lesions were located outside bones accompany soft tissue masses with scattered grit calcification. Two cases exhibited open-herding appearance. ③Clear cell chondrosarcoma in 3 cases:The lesions showed osteolytic bone destruction combined with extraosseous tissue masses included rarely calcification on CT imaging. The hypo-intense septa were seen on T₂WI and the peripheral and septal enhancement with wreath- or shell-like appearance was showed on post-contrasted MRI. Two cases demonstrated fluid-fluid level because of hemorrhage. ④Dedifferentiated chondrosarcoma in 2 cases:Two lesions showed "bimorphic features" with different tumors features mixed within the lesion. The tumors constituted by low-grade chondrosarcoma and high-level sarcomas variability, demonstrated osteolytic destruction with unmineralized soft-tissue mass. Conclusion CT and MR imaging features of uCHS have no obvious specificity, but the examinations play important roles in depicting the location, internal structure and its correlation with the adjacent structures, as well as in formulating the plan of treatment and assessing the efficacy of treatment. The final diagnosis should be relied on pathologic and immunohistochemical examinations.

Abstract:
Anticoagulants are drugs that prevents blood coagulation by inhibiting or blocking certain parts of the organism's physiological coagulation mechanism, which are mainly used in the prevention and treatment of thromboembolic diseases. Traditional oral anticoagulants can interfere with multiple targets in the coagulation mechanism, represented by warfarin. Although warfarin has remarkable advantages on the prevention and treatment of thromboembolic disease, the disadvantages of it also limited the popularity among both doctors and patients in clinical practise. Compared with traditional oral anticoagulants, New oral anticoagulants (NOACs) inhibit blood coagulation pathways in particular of the clotting factors, for example thrombin inhibitors (dabigatran etexilate) and blood coagulation factor X inhibitors (rivaroxaban apixaban; edoxaban; the Ⅲ clinical study of betrixaban), NOACs work fast, metabolic quickly, do without regular monitoring of blood coagulation indexes, interact less with food and drug, risk less bleeding events, especially intracranial hemorrhage. At present, NOACs have been widely used in nonvalvular atrial fibrillation of anticoagulant therapy, prevention of deep vein thrombosis and the secondary prevention of acute coronary syndrome. So more clinical studies about NOACs were conducted to further define the scope of its indications, dosage adjustment, optimization of individual application. These new progress makes the new oral anticoagulants walking in the forefront of the times, provided more choices to make the best treatment plans for patients in need of anticoagulation. Here we provide a brief overview in the drug characteristics and clinical research progress of NOACs to promote standardized application of NOACs.

Abstract:
As an systemic inflammatory mediator, procalcitonin (PCT) is one of the new inflammatory markers which have been studied recently. Compared with other biological markers, PCT has higher sensitivity and specificity, and can be more effective to distinguish bacterial infection from other inflammatory processes. PCT is not only a good indicator screening for infectious diseases, because of serum PCT having different concentrations in viral infection, bacterial infection (including Gram-positive bacteria and Gram-negative bacteria), fungal infection or other atypical pathogens infection, it is also effective index that can identificate different pathogenic bacteria infection. The initial serum concentration of PCT has some guiding significance for antibiotic therapy, and in the whole course of treatment, it is important to monitor and manage PCT for evaluating if continuing or discontinuing antibiotics. Moreover, the dynamic changes of PCT are of great significance in evaluating the severity and prognosis of infection, and judging the treatment effectiveness. At the same time, PCT-guided antibiotic treatment can reduce the use of antibiotics, shorten the hospitalization time of patients and reduce the hospitalization costs, thereby reducing the incidence of antibiotic resistance, social cost and increasing social benefit in the whole. Although there were many studies about PCT in different types, different experimental design methods and that had selective biases, the cut-off values or threshold of PCT is difficult to define in identification of infection types, assessment of disease severity and prognosis. Up to date, evidence of very low to moderate quality, with insufficient sample power per outcome, does not clearly support the use of procalcitonin-guided antimicrobial therapy to minimize mortality, clinical severity,reinfection or duration of antimicrobial therapy of patients. It still needs further study.This artical reviewed the clinical application and research progress of procalcitonin.

Abstract:
To improve the quality of primary medical care, it is crucial to strengthen the general practitioner (GP) training and modify the training methods. As one of the first batch of participants receiving the RCGP (Royal College of General Practitioners) International (China) Training, I hereby give a brief introduction to the forward-looking ideas and advanced technology of the GP training in the UK and shared my experience of its primary application. The GP training programme focuses on cultivating one's learning ability in five steps:learning facts guiding cause factor analysis Q&A about general processing principle praise and approval independent thinking about solutions. The establishment of adult learning pattern can help GPs to develop continuous learning ability and thus trainees having different learning styles will be assigned to form a study group to carry out various activities, such as role playing, group discussion and videotaping, in order to produce better learning outcomes. Clinical teachers play an important role in the GP training programme. They are responsible for formulating clinical teaching syllabuses, developing individualized teaching methods according to the trainees' learning styles and establishing a feedback system (trainee to trainee, trainee to clinical teacher and between clinical teachers) that is effective in identifying problems in clinical teaching and bettering teaching skills. The diagnostic kit is usually applied to the clinical reception training so as to increase the reception efficiency and cultivate more and younger GPs. Considering the differences in national situations and traditions between China and the UK, both of the Chinese clinical teachers and trainees are required to adapt themselves to the UK's GP training programme for practical use. To be specific, clinical teachers should pay attention to the shift from the role of an instructor towards a guide and co-participant. Since the optimized training techniques, such as role playing, videotaping and diagnostic kit training are widely recognized by the GP trainees, these techniques can be extensively applied to the GP training in China. With regard to trainee appraisal, clinical teachers should value their trainees' performance on cultural science, morality, legal compliance, learning ability, collaboration ability and leadership, as well as their understandings of theories and command of techniques. To learn from the UK's GP cultivation and training is beneficial to standardize domestic GP training and cultivation.

Abstract:
Objective To study the effect of monopathy payment through comparing the hospitalization and medicare payments of monopathy and non- monopathy in Shaanxi province, put forward policy recommendations targeting the existing problems in single disease payment, and provide a basis for the improvement of payment methods in China. Methods The participants in Shaanxi Province between 2007 and 2012 were enrolled into this study and assigned into monopathy group and non- monopathy group according to the monopathy payment (whether or not single disease). The number of inpatients, hospitalization expenses, hospital details and compensation costs were compared between the two groups. The Mann-Whitney U test was performed by SPSS statistical software. Results ①Between 2007 and 2012, the average hospitalization cost of monopathy was lower than that of non- monopathy, especially in 2011, the hospitalization cost of monopathy was 1 323 yuan, and non- monopathy was 3 467 yuan. ②The hospital days of monopathy was generally less than 7 days, however, non- monopathy was usually higher than 9.3 days. ③ Between 2007 and 2009, the ratio of monopathy patients accounted for more than 12%, but the proportion decreased to 8.89% in 2010, and further to 5% in 2011 and 2012. ④From the year 2011, the actual compensation ratio (50.45%) for monopathy was lower than that for non- monopathy (67.82%). Conclusion ①From the average hospitalization costs and hospital days, the effect of local NCMS single disease payment method is obvious. ②The reduction in the proportion of single disease patients prompted that the local monopathy payment model still needs some improvement. It is recommended to gradually expand the coverage of monopathy, the implementation of disease diagnosis related classification (DRGs). ③The proportion of monopathy payment that is higher than non- monopathy is not conducive to the promotion of single disease model. It is recommended that the local need to pay more attentions to the improvement of the actual compensation ratio of single disease, and explore the promotion of payment reform.

Abstract:
Objective To investigate the effects of nicotinamide on blood glucose control in gestational diabetes mellitus (GDM) rats by detecting the mitochondrial superoxide level and anti-oxidative enzymes. Methods Diabetes Mellitus (GDM) rats were administered nicotinamide at daily doses of 50, 100 or 200 mg/kg body weight by oral gavage from gestation days 6 through 20. Blood glucose level was measured on gestation day 21. Brain tissue of the fetus rat and skeletal muscle of GDM rats in each group were collected. The expression and activity of anti-oxidative enzymes, including SOD1, SOD2 and Catalase were measured by RT-PCR and Western blot. Results Nicotinamide significantly lowered the blood glucose in GDM rats and decreased mitochondrial superoxide level in the fetus neurons. Superoxide dismutase 2 (SOD2) was induced by nicotinamide in GDM rats (P<0.05). Nicotinamide also promoted SIRT3 activity and deacetylated SOD2 in GDM rats (P<0.05), which enhanced SOD2 activity and altered mitochondrial ROS. Conclusion Nicotinamide promoted SIRT3 activity to deacetylate SOD2, which activated SOD2 and affected the mitochondrial ROS in GDM rats. Therefore, nicotinamide could potentially treat GDM patients in clinical application.

Abstract:
Objective To understand the condition of low back pain and analyze the influencing factors related to low back pain among nurses in intensive care unit (ICU),so as to supply evidence for reducing and preventing occupational injuries. Methods This was a cross-sectional study. From June, 2015 to August, 2015, we investigated 202 ICU nurses from 4 hospitals in Zhejiang province, which were selected by convenience sampling method. General social demographic characteristics, condition of low back pain and the relevant influencing factors of low back pain were investigated. The mean±standard deviation, composition ratio and rate were used to describe the condition of low back pain. Multivariate unconditional logistic regression analyses were used to explore the relevant influencing factors of low back pain. Results The 143 of 202 participants had a vocational low back pain. The prevalence of occupational low back pain among ICU nurses was 70.8%. Among ICU nurses who had lower back pain, in the past year, 40.1% of them had a total duration of illness more than 30 days, 19.3% of them reduced daily activities time for more than 30 days, and 21.8% of them had received examination and treatment. The main factors, which were related to occupational low back pain among ICU nurses were working years (OR=2.17, 95% CI:1.38-3.66), times of lifting heavy loads(OR=2.14, 95% CI:1.18-4.35), occupational stress (OR=1.83, 95% CI:1.24-2.99), physical exercise (OR=0.62, 95% CI:0.41-0.86) and moonlit night shift (OR=2.37, 95% CI:1.53-3.72). Conclusion The condition of low back pain among ICU nurses was serious. Interventions related to influencing factors, such as strengthening the training to correct bad posture, strengthening physical exercise and making scientific work scheduling, should be taken to reduce the incidence of low back pain.

Abstract:
Objective To explore the psychological resilience of nurses in intensive care unit (ICU) in three grade general hospital and its related influencing factors, so as to provide evidence for psychological intervention of ICU nurses. Methods Connor-Davidson psychological scale was used to investigate the psychological elasticity of 1 082 ICU nurses in three general hospitals in Hainan Province from January, 2017 to March, 2017, and the influencing factors were analyzed by multiple Logistic regression. Results The average score of resilience of ICU nurses (57.61±14.16) was significantly lower than that of the national norm (65.4±13.9), and the difference was statistically significant (P<0.01). Correlation analysis showed that resilience and its 3 dimension scores were positively related to ICU nurses' educational background, working years and night shift (P<0.05). There were significant differences in psychological resilience scores of ICU nurses between different gender, educational background, professional title, working years, night shift status, employment characteristics, workplace violence experience, and workplace tension (P<0.05). Multivariate Logistic regression showed that educational background, working years and night shift were the main factors influencing the resilience of ICU nurses[OR=1.928, 95%CI:1.214-3.013; OR=1.627, 95%CI:1.085-2.683; OR=2.064, 95%CI:1.542-3.117]. ROC curve was used to evaluate the effect of logistic regression model, and its AUC (95%CI) was 0.924 (0.875-0.996). Conclusion The psychological resilience of ICU nurses is low, and there are many factors affecting their resilience. The nursing managers should intervene according to the corresponding factors so as to improve the psychological status of ICU nurses.

They were divided into training group (50 cases) and control group (50 cases) according to the random number table method. The control group was given routine nursing method, the training group gave the time theory based rehabilitation training. left ventricular ejection fraction (LVEF), 6 min walking distance (6 MWD), New York Heart Association Functional Classification (NYHA), Seattle angina questionnaire (SAQ) score and 6 months of dysmenorrhea were compared between the two groups. Results The levels of LVEF and 6MWD in the two groups after 6 months discharge were significantly higher than those before the intervention (all P<0.05). The NYHA classification in two groups 6 months after discharge was significantly lower than that before intervention (P<0.05). The levels of LVEF and 6MWD in the training group 6 months after discharge were significantly higher than those in the control group (all P<0.05). The NYHA classification in the training group 6 months after discharge was significantly lower than the control group (all P<0.05). The score of frequency of angina pectoris in the control group 6 months after discharge was significantly higher than that before the intervention (P<0.05). All quality of life scores in the training group 6 months after discharge were significantly higher than those before the intervention (all P<0.05). The quality of life scores in the training group were significantly higher than those in the control group 6 months after discharge (all P<0.05). The incidence of adverse events in the training group was significantly lower than that in the control group (all P<0.05). Conclusion The time theory based rehabilitation training can effectively improve the cardiac function and quality of life of patients with unstable angina pectoris, which is worthy of clinical application.
