Abstract:
Objective To investigate the cognition and practice on evidence-based medicine (EBM) among the general practitioners (GPs) in Beijing urban area. Methods A proportioned stratified random sampling method was used to sample among 148 community health service centers in Beijing urban area, and 26 community health service centers and 108 attached community health service stations were surveyed. A total of 477 GPs were investigated and 439 questionnaires were available. Results ①29.2% of the GPs were with a good understanding of the concept of EBM than other items, and relatively poor understanding of the procedures of EBM. Their understanding of EBM was significantly different among GPs with different ages, academic qualifications, licensed types, years of service and professional titles (P<0.05). ②The GPs had a positive attitude toward EBM. Eighty-two point two percent of the GPs agreed that the best evidence might played an important role in clinical practice, 82.2% of the GPs agreed on the important role of clinical practice guidelines for individual treatment. There was a statistically difference in the attitude of the GPs with different degrees in EBM (P<0.05). ③The GPs had a great demand for EBM. The most urgent need of GPs was to regularly participate in EBM knowledge and skills training (77.9%). Secondly, The community should provide the medical staff with the facilities for evidence-based practice (77.4%). Conclusion GPs have gradually realized the importance of EBM, and their need for EBM is also urgent. Therefore, in order to improve the current situation of GPs in practicing EBM, we should make full use of existing resources to promote EBM.

Abstract:
Objective To explore the differences in expression level of miR-181b (miR-181b) in CD19⁺ B lymphocytes in patients with chronic lymphocytic leukemia (CLL) and analyze its clinical significance. Methods Fifty patients with CLL, and collecting healthy controls 20 cases. All patients took 15ml of peripheral blood and the total RNA of CD19⁺ B lymphocyte was extracted after sorting with CD19 magnetic beads, and the expression lever of miR-181b was measured by TaqMan probe. The difference expression lever of miR-181b in prognostic groups were analyzed, such as clinical stages, Serological indicators, CD38, Zeta chain related protein kinase-70, immunoglobulin heavy chain variable region and Abnormal genetics. Survival analysis was performed on the above indexes. Results ① The expression lever of miR-181b in CD19⁺ B lymphocytes in Fifty patients with CLL was significantly lower than the healthy controls (P<0.01). ② The expression level of miR-181b in different groups:according to the prognosis of FISH groups, the poor prognosis group was significantly lower than the favorable prognosis group (P<0.05), ATM deletion group was significantly lower than the ATM normal group (P<0.05), There was no statistical difference in the expression level of miR-181b in other groups (P>0.05). ③ Survival analysis:The expression level of mir-181b was divided into low expression group and high expression group by median of 0.033. The comparison showed that the OS of mir-181b low expression group was shorter than the mir-181b high expression group (P<0.05). Combined COX multivariate analysis with poor prognostic factors, the results showed that the high-risk group of FISH prognosis group, P53 deletion, ATM deletion, miR181b lower expression were all independent prognostic factors affecting survival (P<0.05). Conclusion The expression level of mir-181b in CLL patients is significantly lower than normal people, and the low expression of mir-181b is an independent prognostic factor of CLL.

Abstract:
Objective To discuss the value of transcranial Doppler (TCD) combined with P_ETCO₂ in the evaluation of cerebrovascular reserve in patients with cerebrovascular stenosis. Methods Total 78 patients with cerebrovascular stenosis were divided into single vascular stenosis group (32 cases) and multiple vascular stenosis group (46 cases), and 45 normal health patients were assigned into the control group. TCD combined with P_ETCO₂ were used to evaluate the cerebrovascular reserve function. Results There was no statistically significant difference in the vasodilation reserve and the total blood vessel reserve among the three groups (both the light side and the heavy side), all P>0.05. The systolic reserve of vasorelaxation in serious side was significantly lower in the multivessel stenosis group than that in the control group (t=2.417, P<0.05). The vascular dilation reserve value and vascularity in the single vessel stenosis group were obviously lower than those in the multi-vessel stenosis group (all P<0.05). There was no significant difference in the P_ETCO₂ during terms of quiet breathing, hypocapnia, and hypercapnia among the three groups (all P>0.05). The severity of cerebral vascular disease was negatively correlated to the vascular expansion reserve value and the overall blood vessel reserve value (all P<0.05), and no correlation with vascular contraction reserve (P>0.05). Conclusion TCD combined with P_ETCO₂ is a kind of effective method to evaluate cerebrovascular reserve function. With the increase of severity of cerebral vascular stenosis, cerebral vascular reserve might significantly decrease, which will result in the alteration of risk of stroke.

Abstract:
Objective To explore the method of preparing the improved retrograde inherent arterial island flap and evaluate its clinical efficacy for the defect of finger distal segment. Methods The clinical data of 11 patients undergoing repair of finger distal segment defect with the improved methods for reverse homodigital island flap in our hospital between January, 2016 and December, 2016 were reviewed. The reverse homodigital island flaps were from 1.0 cm ×1.5 cm to 2.5 cm × 2.5 cm in size. The flap ran along the axis of arterial and nerve, with the two boundaries not more than the midpoint of the dorsal of the hand, and the rotation point was marked by a quarter of the central phalange. The microscopic equipment separation was used to prepare the skin flap under the microscope. The natural surface of neural tissue was separated to make its free as the flap approached the midpoint of digital pulp, and the proper digital arteries and accompanying venous network were then indirectly isolated. The subcutaneous soft tissue in the flap area was sutured for 2 stitches to cover the exposed nerve, and the carpometacarpal full thickness graft was used to suture the skin area directly. Gypsum was used for the fixation and protection at wrist flexion for one week. The planting bags were removed one week after the surgery to promote the functional exercise in flexion and extension. After 6 months of follow-up, the patients were evaluated for their functions and appearance. Results All of the 11 cases of flaps survived without venous or arterial crisis. Postoperative follow-up showed that the appearance of the repaired finger was similar to normal finger, with satisfied sensation and movement function. Conclusion The improved reverse homodigital island flap for the defect of finger distal segment is easy to operate, which can shorten the operation time, ensure the safety of surgery (flap survival). It can effectively protect the proper digital arteries and accompanying venous network in the preparation of the flap, avoid the venous or arterial crisis, with satisfied appearance and function and minor injury, which is an ideal operation method for the repair of finger.

Abstract:
Objective To evaluate the clinical significance of flow cytometric bead assay (FCBA) test in diagnosis of immune-mediated platelet refractoriness (IPR) and in the differential diagnosis of IPR from non-immune mediated platelet refractoriness (NIPR). Methods FCBA was established and used to detect the HLA-Ⅰand HLA-Ⅱantibody of 107 patients with hematopathy who relied on platelet transfusion. There were 29 patients of IPR, 26 patients of NIPR and 52 patients of NPR. The sensitivity and specificity of the approach for the diagnosis of IPR were evaluated, and the correlation between the levels of anti-HLA-Ⅰ/HLA-Ⅱand 24 h corrected count increment (CCI) were analyzed. Results The positive percentage of 55 PR patients' HLA antibodies was 52.73%. The total positive rate of HLA antibodies in IPR group was 100%, which compared with the positive percentage of NIPR group (0.0%) and NPR group (13.46%) both had significant statistical difference(all P<0.01). The results showed that for the diagnosis of IPR, anti- HLA-Ⅰand HLA-Ⅱ had the sensitivity of 89.66% and 55.17%, the specificity of 85.71% and 14.29%, the positive predictive value of 96.30% and 72.72%, the negative predictive value of 66.67% and 7.14%, and the total efficiency of 90.82% and 34.73%, respectively. The concentration of anti-HLA-Ⅰand anti-HLA-Ⅱantibody both was negatively correlated with 24 h CCI(r=-0.594, P<0.05; r=-0.525, P<0.05). Conclusion Flow Cytometric Bead assay in detecting HLA-Ⅰantibody has high specificity, and it is proved to be of great value for the diagnosis of IPR and for differential diagnosis of IPR from NIPR.

Abstract:
Objective To investigate the changes of macular foveal retinal thickness (FRT) after the phacoemulsification and intraocular lens implantation in type 2 diabetics patients. Methods A total of 60 cases of cataract with phacoemulsification and intraocular lens implantation were recruited. Thirty cases of 60 Patients with diabetics were in diabetic group, and others with age-related cataract were in control group. FRT were measured by using optical coherence tomography (OCT) before phacoemulsification and 1 day, 1 week, 1 month, and 3 months after the surgery. The changes of FRT were compared in the two groups. Results In the diabetic group, the preoperatively mean fovea thickness was (216.24±19.44)μm, and postoperatively mean fovea thickness was (216.20±18.94)μm at 1 day after the operation, (216.94±19.00)μm in 1 week after the operation, (235.17±24.42)μm in 1 month after the operation, and (227.52±25.36)μm in 3 months after the operation. In 1 week, 1 month and 3 months after the operation, the difference in FRT was significant(all P<0.05). In the control group, the FRT was thickened at 1 day, 1 week, and 1 month after the surgery, which decreased slightly at 3 months after the surgery, but with no statistical difference (all P> 0.05). The difference of the mean fovea thickness between the two groups at 1 month and 3 month after surgery was significant (all P<0.01). Macular edema was found in 5 eyes (5/30, 16.67%) in the diabetic group, and none (0/30) in the control group. Conclusion The thickness of the fovea of retina increases significantly after phacoemulsification in diabetics and the morbidity of macula edema increases as well.

Abstract:
Objective To investigate the clinical characteristics and prognostic factors of primary intraventricular hemorrhage (PIVH). Methods A retrospective study was conducted. The data of PIVH patients in Jinhua Municipal Central Hospital from January, 2011 to January, 2016, including demography, medical history, radiological imaging and prognosis, was collected to evaluate the etiological causes, clinical features and prognostic factors. Results A total of 41 patients with PIVH were enrolled in the study finally, which account for 3.8% of patients with hemorrhagic stroke. In all 41 patients, 61.0% were male (25 cases) and the mean patient age was (50.1±12.3) years. Hypertension was the most common medical history (20 cases, 8.8%) and headache was the most common initial symptom (25 cases, 61.0%). According to cause of hemorrhage, patients were divided into idiopathic group (24cases, 58.5%) and vascular structural abnormality (VSA)-related group (17 cases, 41.5%). Age, proportion of hypertension and GCS in the idiopathic group were all significantly higher than those in VSA-related group (P<0.05). According to the modified Rankin scale (mRS), 25 cases (61.0%) have favorable outcome (mRS:0-2) and 16 cases (39.0%) have unfavorable outcome (mRS:3-6) during the 6-month follow-up. The unfavorable outcome group have significantly higher Graeb score and proportion of acute hydrocephalus, and lower GCS than favorable outcome group (P<0.05). The idiopathic group has better outcome than VSA-related group (P<0.05). Conclusion PIVH is a rare type of hemorrhagic stroke with a poor outcome. We recommend routine cerebral angiography to identify etiological cause. High Graeb score, low GCS, acute hydrocephalus and VSA-related PIVH are associated with poor prognosis.

Abstract:
Objective To evaluate the safety and efficacy of expert type intramedullary nail (expert tibial nail, ETN) in the treatment of open distal tibial fracture. Methods Total 22 cases of open distal tibial fractures in our hospital between March, 2013 and September, 2014 were enrolled into this study. There were 14 males and 8 females, with a mean age of 40.4 (from 22-56) years old, including 10 Gustilo type Ⅰ, 8 type Ⅱ and 4 type ⅢA. All patients were debrided and close reducted and fixed with ETN in the emergency treatment. The duration of surgery, blooding volume, time for clinical heal of the wound and fracture, and incidence of complications were analyzed. All patients were followed up by periodic X-ray examination. Functional outcomes were evaluated according to the Johner-Wruhs standard one year after surgery. Results All 22 patients were followed up for 9-24 months (average 16.4 months). The mean time of surgery was 75 mins (55-110 mins). The intraoperative bleeding volume was 65ml (40-100 ml). Superficial infection occurred in 2 cases with Gustilo typeⅡand healed by dressing. Two cases of type ⅢA fractures were necrotic and covered with skin flap, with deep infection in 1 case. The fractures healed 4.8 months (from 3.5-13.6 months)after surgery, Anatomical or functional reduction were achieved and maintained in all cases. Two fractures of delayed union healed by dynamization through removing the proximal locking nail. The nonunion of bone occurred in 1 case, which healed by replacing the larger diameter nail and bone graft. No nail breakage, malunion or limb shorting occurred. By Johner-Wruhs criteria, the final outcomes were excellent in 12 cases, good in 7 cases and fair in three. The good rate was 86.4%. Conclusion Expert Tibial Nail has the advantages of minimally invasive trauma, stronger fixation, better functional recovery for the treatment of open distal tibial fractures. It is safe and effective in the treatment of Gustilo type Ⅰ, Ⅱ fractures with low incidence of complications. But it is less effective for type ⅢA fractures with serious tissue injury.

Abstract:
Objective To analyze the colonoscopy-assisted laparoscopic surgery in the treatment of early colorectal tumor, and further elevate the application value of them in the treatment of early colorectal cancer. Methods From January, 2014 to May, 2017, a total of 31 early colorectal tumor patients were treated with colonoscopy-assisted laparoscopic surgery in our hospital. Locations of colorectal lesions were explored by colonoscopy. According to the rapid frozen pathological results, laparoscopic surgery was selected. Results All patients were treated with colonoscopy-assisted laparoscopic surgery successfully, with no conversion to laparotomy. Among 22 cases of preoperative diagnosis of stageⅠcolorectal cancer, there were 20 cases of intraoperative and postoperative diagnosis of stageⅠ (13 cases of T1N0M0, 7 cases of T2N0M0) and 2 cases of stageⅢ (T2N1M0). There were 9 cases of preoperative diagnosis of precancerous lesions, 2 of which were diagnosis of high grade intraepithelial neoplasia and 7 cases were diagnosis of high grade intraepithelial neoplasia with carcinogenesis.6 cases were under polypectomy at the same time, the rapid frozen pathological results proved to be a low level adenomatoid polyp during the operation, and no additional surgery was performed. All patients were examined by colonoscopy half a year after operation. After that, 1 time a year was reviewed, and tumor markers were monitored at the same time. All patients were followed up 6-42 months, with a median of 32 months.Most of the patients were alive without recurrence except one case died of cerebral infarction 2 years after operation. Conclusion Laparoscopy combined with colonoscopy in treatment of early colorectal tumor has advantages of both endoscopy, especially suitable for lesions with difficult location or complete resection, which can improve surgical accuracy and safety.

Abstract:
Objective The effect of concurrent chemoradiotherapy on the efficacy, safety and prognosis of advanced cervical cancer was studied comparing with radiotherapy alone. The expression levels of p53 and Bax in tumor tissues were taken as the starting point to discuss the curative effect. Methods Sixty-five patients with advanced cervical cancer (stage Ⅱb~Ⅳ) who were treated by radiotherapy alone in January, 2009 January, 2013 were selected as control group. Sixty-five patients of concurrent chemoradiotherapy were selected for the same period and the same condition as the observation group. The radiotherapy scheme was the same as the control group. The chemotherapy was combined with the PF regimen, 1 times every 3 weeks, and the chemotherapy was 3 times. The short-term effect (nearly 3 months), the incidence of adverse reactions, the prognosis (3, 5 years, local recurrence, distant metastasis) were compared between the 2 groups, and the expression of P53 and Bax before and after the treatment were compared and analyzed. Results The effective rate of the observation group was higher than that of the control group (63.1% to 43.1%, P<0.05). The 3-and 5-year survival rates in the observation group were 78.5% and 63.1%, respectively, higher than those in the control group 61.5% and 40.0% (P<0.05). The local recurrence rate and distant metastasis rate in the observation group were 30.8% and 23.1% respectively, lower than those in the control group 47.7% and 43.1% (P<0.05). The incidence of bone marrow suppression and gastrointestinal reactions in the observation group was significantly higher than that in the control group (P<0.05). There was no significant difference in the incidence of liver and kidney function injury, radiation proctitis and radiation cystitis in the two groups (P>0.05), which could be tolerated in patients with adverse reactions and did not significantly affect the treatment. After the treatment, the positive rates of P53 and Bax in the two groups increased, and the increase in the observation group was higher than that in the control group (P<0.05). Conclusion Compared with radiotherapy alone, synchronous radiotherapy can improve the effectiveness of the treatment of advanced cervical cancer and improve the prognosis of patients. Although the incidence of toxic and side effects is high, the patient can be tolerated after active treatment. The mechanism may be related to the up-regulation of the expression of Bax and the inhibition of P53 process, thus improving the chemosensitivity of the patients.

Methods A prospective cohort study was used to select 126 patients of tuberculosis combined with hepatitis B in our hospital from January, 2016 to January, 2017, according to the random number table, the subjects were randomly divided into A (control) group, B (lamivudine group) and C (entente Cave) group, 42 cases in each group for 6 months according to different treatments, the liver function, HBV DNA negative conversion rate, the effect of pulmonary tuberculosis and the occurrence of adverse reactions were observed in all groups, and the data were analyzed by SPSS 21.0 statistics software. Results After 6 months of treatment, the level of ALT, AST and TBIL in group B and C was significantly lower than that in group A (P<0.05). The ALT and TBIL levels of C group were lower than that of B group (P<0.05). The absorption of chest lesions and the rate of HBV DNA turned negative conversion rate in group C were significantly higher than those in the A group (P<0.05), the incidence of total adverse reactions in group B and C was lower than that in group A (P<0.05). Conclusion The anti-tuberculosis regimen combined with lamivudine and entecavir has a certain advantage in reducing the liver damage and protecting the liver function of anti-tuberculosis drugs. It may be more beneficial to the treatment effect of anti-tuberculosis drugs on the premise of normal liver function. The indexes of liver function and HBV DNA negative conversion rate in entecavir group were better than those in lamivudine group, and the safety of the two drugs is acceptable.

Abstract:
Objective To investigate the incidence of retinopathy of prematurity (ROP) in our hospital and the risk factors of the disease. Methods A total of 616 preterm infants who were admitted to our hospital from November, 2015 to June, 2017 and met the 2014 screening criteria for retinopathy of prematurity were selected. All the subjects were screened for fundus diseases in preterm infants. The results were divided into ROP group and non-ROP group. The ROP group was graded and the incidence of ROP was calculated. The clinical data of all subjects were collected. The general conditions, clinical diagnosis and treatment status, complications, and maternal related conditions were compared between the two groups. Univariate analysis and Logistic regression analysis were used to analyze the risk factors for ROP. Results In 616 preterm infants, there were 47 patients with ROP and the incidence was 7.7%. According to the international ROP classification criteria, 3 cases were in zone Ⅰ, 27 cases were in zone Ⅱ, 18 cases were in zone Ⅲ. And 21 cases were in stage 1, 13 cases in stage 2, 12 cases in stage 3, 1 case in stage 4A, 1 case in additional lesions of zone Ⅱ and 1 case in aggressive posterior RO (AP-ROP). The general gestational age, birth weight, head circumference, 5 min Apgar score, and asphyxia were statistically significant between the two groups (P<0.05); oxygen and oxygen inhalation time, PS, EPO, blood transfusion, the use of aminophylline and caffeine showed statistical significance between the two groups (P<0.05); among the complications, bronchopulmonary dysplasia, patent ductus arteriosus, and intraventricular hemorrhage were statistically different between the two groups (P<0.05); the use of hormones and magnesium sulfate in the maternal condition was statistically significant between the two groups (P<0.05). Multivariate Logistic regression analysis showed the differences between ROP and non-ROP groups in gestational age (OR=0.730, 95% CI:0.658-0.815, P<0.001), oxygen intake (OR=0.159, 95% CI:1.050-37.468, P=0.044), intracranial hemorrhage(OR=0.018, 95% CI:0.001-0.621, P=0.026) and the use of caffeine (OR=0.049, 95%CI:0.003-0.754,P=0.031) were statistically significant. Conclusion The incidence of ROP is 7.7%. The gestational age, oxygen consumption, use of caffeine, and important complications (intracranial hemorrhage) are related to the occurrence of ROP.

Abstract:
Objective To investigate the iron overload and its influencing factors in patients with aplastic anemia (AA). Methods A total of 200 adult AA patients were selected in Department of Hematology of the First Hospital of Ningbo, the Second Hospital of Ningbo City and the Fuyang Hospital Affiliated to Anhui Medical University from March, 2014 to March, 2018. The clinical data of patients were collected. The serum ferritin (SF) levels were measured by radioimmunoassay. The levels of total iron binding force (TIBC) and serum iron (SI) were determined by the colorimetric method of ferrozine. The levels of soluble transferrin receptor (sTfR) and transferrin (Tf) were determined by immunoturbidimetry. The transferrin saturation (TS) was calculated. Results In 200 patients with AA, the SF was 1 253.25(519.06, 1 757.17) μg/L, SI was 33.31 (21.60, 56.66) μmol/L, TS was 62.02%(30.88%, 74.60%), the Tf was 1.87 (1.60, 2.71)g/L, and the sTfR was 0.93 (0.54, 2.10)mg/L. In 200 patients with AA, iron overload occurred in 29 patients, with an overload rate of 14.5%. The proportion of iron overload in males, heavy AA, blood transfusion >8 U and coinfection were higher than that of without iron overload (P<0.05). The age, etiology and course of disease were not associated with iron overload in AA (P>0.05). Logistic regression analysis showed that men, blood transfusion >8 U and coinfection were independent risk factors for iron overload in AA (P<0.05). Conclusion The incidence of iron overload in AA patients is high. Males, blood transfusion >8 U and coinfection are independent risk factors for iron overload in AA patients.

Abstract:
Objective To understand the psychological status of patients with type 2 diabetes in Weifang community, and to analyze the factors affecting the psychological status of patients with type 2 diabetes mellitus in contracting community health service and to provide evidence for general practitioners having more targeted psychological counseling for patients with type 2 diabetes. Methods A total of 529 patients who live in Weifang community from 2010 till now and have already enrolled in community health service were surveyed by systematic sampling method and health questionnaire for Symptom Checklist 90 (SCL-90), social support revalued scale and a questionnaire involving population characteristics. At the same time, the influencing factors and social support condition of psychological status of patients with type 2 diabetes mellitus in contracting community health service were analyzed. Results In this study, total score and each factor score in SCL-90 of patients with type 2 diabetes mellitus in contracting community health service were higher than the national norm. Age, job, income, and occupation of patients with type 2 diabetes mellitus have effects on some factors of SCL-90. The course of diabetes has an effect on all factors of SCL-90, and a few have significant effects. There was a significant negative correlation between social support and factors in SCL-90 of type 2 diabetes mellitus in contracting community health service. Conclusion The psychological health of the patients with type 2 diabetes mellitus in contracting community health service is not optimistic. Different demographic factors can have different effects on the psychological condition of type 2 diabetes mellitus in contracting community health service. General practitioners should give more effective psychological counseling and social support to patients with type 2 diabetes mellitus in contracting community health service who have different demographic characteristics.

Abstract:
Objective To analyze the tendency of diabetes mellitus patients in choosing the first-contact medical institution and reason for referral and to provide evidences for hierarchical medical service implementation. Methods We compared the seeking tendency and referral reasons between the two groups of diabetes mellitus patients, including signed group and ambulatory group, in the suburban community of Shanghai Pudong District. Descriptive statistical methods, χ² test, constituent ratio, and percentage were applied to analyze the quantitative data. Thematic frame analysis and SWOT method were adopted to analyze the qualitative data. Results We enrolled 496 diabetes mellitus patients in the signed group, and 464 patients in the ambulatory group. The tendencies between two groups of patients in choosing the first-contact medical institution showed no statistical significance (P>0.05). The reasons for referral included medical technical level, drug or laboratory test deficiency, travel distance to facility, medical service quality, further examinations, and other reasons. Comparing the two groups, there were statistically significant difference among medical service quality and other reasons(P<0.05 or P<0.001, respectively). Conclusion The results revealed that the contracted mode is more effective and sustainable to manage and serve the patients. Equipping the ancillary departments, sharing the pharmacy information and laboratory results, three-level linkage, and government support are key points to improve the ability of first-contact and continual treatment of the community hospitals and to implement the hierarchal medical service.

Abstract:
Objective To investigate the effects of Mtb-HAg on the production of IFN-γ and IL-17 in γδ T cells from peripheral blood of peripheral blood mononuclear cell (PBMCs) from normal people (HC) and tuberculosis patients (TB). Methods PBMCs were isolated from the peripheral blood of 12 HC and 12 TB patients and cultured for 12 days. The cells in the experimental group were stimulated by using Mtb-HAg for 2 h and then further cultured for 4 h in Monensin; while the cells in the negative control group without receiving the stimulation with Mtb-HAg. The cells were harvested and labeled with fluorescent-labeled McAb for surface and intracellular staining. The γδ T cells in both groups were assayed by flow cytometry for the production of IFN-γ and IL-17 cells relative proportions. Results The γδ T cells in both experimental group and negative control group were able to produce IFN-γ. IFN-γ produced by γδ T cells stimulated by Mtb-HAg was significantly higher than that by cells without receiving stimulation with Mtb-HAg (P<0.001), and there was significant difference between TB group and HC group (P<0.001). In HC group,the rate of γδ T cells producing IL-17 decreased in both experimental group and negative control group without statistical significance difference, however, in TB group, the same trend showed significant difference between the experimental group and negative control group. Conclusion The γδ T cells from PBMCs in TB patients are sensitive to the stimulation with Mtb-Hag,but its ability to produce IL-17 decreases obviously.

Abstract:
Parkinson's disease (PD) is a kind of extrapyramidal nervous system denatured disease, which is mainly manifested as motor symptoms and non-motor symptoms. Among them, motor symptoms mainly include non-autonomous tremor, slow movement, walking balance dysfunction and muscle rigidity. In recent years, the quality of life of PD patients after treatment is directly affected by non-movement symptoms and more and more scholars at home and abroad attaches importance to it. At present, the related pathogenesis of non-movement symptoms have not been clarified. Some scholars pointed out that the occurrence of non-movement symptoms is controlled by multiple factors, and it is not appropriate to use a single factor perspective to observe the disease. In addition, due to the inconsistency of disease evaluation methods, many results before and after treatment are difficult to be compared with each other, which further aggravates the difficulty of mechanism research. It is worth noting that neuropsychiatric symptoms of Parkinson's disease are one of the most common non-motor symptoms, mainly including emotional disorders, intellectual cognitive disorders and impulse control disorders. At present, most of the neuropsychiatric symptoms of Parkinson's disease are symptomatic treatment, and long-term medication may interfere with the normal operation of other nervous systems, and there is a risk of liver and kidney damage. Neuropeptide is a kind of bioactive peptide widely existing in various tissues of the body, which can strengthen the connection between the nervous system and various systems of the body, and has a good regulation effect on many central nervous system diseases. Among them, substance P, neuropeptide Y, brain-derived nutritional factor, nesfatin-1 and other neuropeptides are closely related to the pathogenesis of neuropsychiatric symptoms in Parkinson's disease. According to their correlation, regulating neuropeptide may be a new breakthrough in the treatment of PD neuropsychiatric diseases.

Abstract:
Atrial fibrillation (AF) is a clinically common arrhythmia, characterized by rapid and disordered atrial electrical activity, with high risk of morbidity and stroke, ventricular dysfunction, heart rate formation damage and atrial thrombi is the main pathophysiological mechanisms leading to progression of symptoms in patients with atrial fibrillation and disease. The incidence of atrial fibrillation reconstructs atrial electrical remodeling and structure, while the atrial remodeling makes the occurrence and maintenance of AF worse. Epidemiological investigation suggests that the incidence of atrial fibrillation is increasing year by year, and often accompanied by thromboembolism and heart failure, with a high clinical fatality rate. At present, the main clinical treatment of atrial fibrillation is rhythmic control, ventricular rate control and stroke prevention. Studies have shown that when patients in the clinical stage of atrial fibrillation, the fatality rate and total medical resources than prevention interventions for atrial fibrillation were significantly increased. Therefore, it is very important to actively control the risk factors of atrial fibrillation. In recent years, the upstream treatment of atrial fibrillation has drawn increasing attention from many scholars. The upstream treatment of atrial fibrillation is a pointer to the etiology and mechanism of AF early intervention, so that the source is cut off or the formation and progression of atrial fibrillation is delayed. The current research on upstream atrial fibrillation treatment focused on angiotensin converting enzyme inhibitors (ACEI), angiotensin receptor block (ARB), aldosterone antagonists (Ald), statins, polyunsaturated fatty acids (PUFA) and other drugs. Recent studies have pointed out that the Chinese medicine treatment of three Fuin AF can also play an important role in in the upstream treatment. The researches on upstream atrial fibrillation treatment discussions will be reviewed in this paper.

Abstract:
Primary cardiac tumors are rare, and clinical epidemiological statistics of the circulatory system is the lowest compared with other systems. Due to the particularity of age, primary cardiac tumors in infants and children are extremely rare, with an estimated incidence of 0.2% according to echocardiographic studies and the autopsy rate in the population is lower. Primary cardiac tumors include benign and malignant:according to statistics, about 90% of primary cardiac tumors are benign, with myxoma the most common and more common with rhabdomyoma; whereas malignant tumors are common with sarcomas. Its incidence is low, but with the progress of clinical auxiliary examination, the prenatal diagnosis rate increases, detection rate of heart damage also increased year by year. Between 1995 and 2005, echocardiography was the most widely used instrument as a non-invasive test. And 2005 CT began to be used in clinical application, while MRI in 2010 can be more effectively detected and assessed of the prognosis and efficacy of cardiac tumors. Occurring in children with heart tumors are mostly primary or no obvious clinical symptoms, but surgery is required only in a minority of cases. Patients with primary cardiac tumors often show as nonspecific symptoms of dyspnea, chest pain, heart palpitations, fever, and weight loss and so on; severe cases can also cause heart rupture, heart and kidney failure, neurological symptoms. Most heart lumps are not suitable for percutaneous biopsy, but pathological findings after surgical resection can prompt a clear diagnosis. At present, the clinical diagnosis mainly depends on echocardiography (transthoracic or transesophageal echocardiography) and cardiac magnetic resonance (MR), and there are some limitations in the rapid and accurate diagnosis of cardiac tumors, which, to some extent also limits the diagnosis of treatment programs, and timely and effective treatment of prognosis is particularly important. However, clinical diagnosis and treatment is still more difficult and timely and effective treatment of prognosis is particularly important. Because of its low incidence, the current reports of the disease are mostly case reports. This article focuses on the classification, diagnosis and treatment of primary cardiac tumors.

Abstract:
With the introduction of the national opinion on deepening the reform of health care system reform, improving the basic medical service system is an important measure to deepen medical reform. The development of general practice is the key to the implementation of hierarchical medical system and talent training is the key link of the disciplinary development. General practitioners are interdisciplinary clinical medical talents with a high degree of integration. It has undertaken continuous medical services such as diagnosis and treatment of common diseases, preventive health care and chronic disease management. The people management involves different ages of sex and their physical, psychological and social health problems. Therefore, the training of general practitioners should cover many fields related to medicine. At present, China has basically established a general practitioner training model with "5+3" as the main part and "3+2" as the supplement. General practice residences standardized training is the best way to train high quality general practitioners. Since 2011,the department of general practice in Peking University has carried out standardized training for general practitioners, actively committed to exploring ways to train general practitioners in line with China's national conditions, adapt to the characteristics of the industry and meet the needs of patients. After nearly eight years of practice, we accumulated rich experience and achieved good results in the management system construction, the optimization training strategy and competency based training. The training system has been improved from the establishment project committee of general practitioners to management team construction and strict selection of faculties. We improved the training quality from tutor management and optimized hospital/community rotation program through the feedback of trainees. A characteristic and diversified evaluation method combining formative assessment and finalization assessment was adopted, in order to steadily improve the skills of the students, and training excellent general practitioners with the aim of "competency based". The department of general practice in Puking University had explored the general practice residences standardized training system with high quality and can be generalized and duplicated. It has been made beneficial exploration to achieve sustainable development in train qualified general practitioner.

Physical examination, hemoglobin test and feeding habit survey were done. Results The anemia rate of 1 650 children was 7.6%(126/1 650),it was 7.3%(57/779) in female children,while 7.9%(69/871) in male children.Many factors were associated with children's anemia, the incidence of anemia of 1-6 year-old children was significantly higher than those of 0-1 year-old children and 6-12 year-old children (P<0.05). The incidence of anemia in rural areas was higher than those in urban areas (P<0.05), and the incidence of anemia in single parent families was higher than that in two-parent families (P<0.05), the incidence of anemia in children with stable and highly educated caregivers is relatively low (P<0.05), but it has nothing to do with sex, the number of compatriots, and the time for breastfeeding. The main causes of 126 cases of children with anemia were iron deficiency anemia and megaloblastic anemia. The concentration of peripheral blood SF, ZnPP, FA and VitB₁₂ in children with anemia were detected, SF in the 1- year-old children was significantly lower than the other two groups. ZnPP was normal in 0-year-old children, but was significantly higher than the other two groups. FA and VitB₁₂ concentrations were normal in three age group, but the concentration of FA in the 6-year-old children was higher than the other two groups. Conclusion The anemia rate of children in this area is still high. The incidence of children in the 1-6 year-old group is the highest, and iron deficiency anemia and megaloblastic anemia are the main reasons. It is necessary to intervene from many aspects simultaneously.

Abstract:
Objective As the demand for medical care continues to grow, quality medical resources cannot fully meet the growing needs of the general public. How to provide convenience for patients and save patient's waiting time to improve outpatient work efficiency is the most concerned issue for patients and is a common problem faced by large public hospitals. Methods Based on the background of ‘Internet+’, this article explores the daily consultation time by half hour as a unit according to the time-based full appointment medical treatment. According to the characteristics of different departments, the number of theoretical consultations per unit time is set to the patient's visit time which can be specific to the minute, and through the provision of an appointment registration, the patient can know the time of his/her visit when making an appointment, understand the registration expert's clinic time, reduce the concentration and detention of the patient, and further protect the patient's medical safety as well as to achieve the diversion of the visiting population and improve the medical environment. Results In the southern part of our hospital, the current situation of supply and demand of hospital outpatient clinics, after the appointment registration, based on the summary of this experience, we proposed a time-based full appointment registration system, which through the nearly half a year of exploration and practice, achieved good results. The system can effectively improve the appointment rate of outpatients, optimize the time distribution of outpatients, and effectively facilitate patients to seek medical treatment. Conclusion The implementation of the multi-channel model with full-schedule appointments has effectively changed the patient's registration habits and improved the appointment rate. At the same time, it has also improved the medical environment and rationalized the allocation of medical resources, which is conducive to the long-term development of the hospital.

Abstract:
Objective To investigate the effect of marital quality on the level of depression in maintenance hemodialysis patients in order to provide a reference for clinical nursing managers to take interventions to reduce the level of depression in hemodialysis patients. Methods A total of 176 hemodialysis patients were recruited from the Second Affiliated Hospital of Wenzhou Medical University, between February, 2016 and February, 2017. They were investigated with the general information questionnaire, marriage perception scale and Chinese version of the Beck depression inventory-Ⅱ. Statistical analysis was conducted using univariate analysis, Pearson correlation analysis to understand the status of the patient's marriage quality and depression level, and to explore the relationship between the two. Results The total score of depression in maintenance hemodialysis patients was (25.88±5.94) points, and the total score of marriage quality was (50.18±12.86) points. Single factor analysis showed that the literacy, duration, and marital quality were the influencing factors of depression in maintenance hemodialysis patients. The quality of marriage in patients with maintenance hemodialysis was negatively correlated with their depression level (r=-0.362, P<0.001). Conclusion Depression is a common psychological disease in maintenance hemodialysis patients. This study shows that the quality of marriage can predict the depression level of maintenance hemodialysis patients, and improving the marital quality of maintenance hemodialysis patients will help improve the depression level of patients.
