Objective To investigate the association between 5-hydroxytryptamine 2A receptor (HTR2A)gene T102C locus polymorphism and schizophrenia,and to provide basis for evidence-based medicine for the genetic background of schizophrenia.Methods PubMed,EMbase,CNKI,WanFang and Vip information databases were used to search full text of all the relevant studies about the association between HTR2A gene T102C locus polymorphism and schizophrenia,which were published during 2003 to 2012.Based on reviewing full text,the data were selected, evaluated and accessed. RevMan 5.1 and Stata 1 2.0 were used to perform the statistical analysis of those studies that were in accordance with the inclusive criteria. According to the different ethnicities, the obj ects were divided into two subgroups as European and Asian to analyze respectively. Also, depending on different inheritances, the obj ects were divided into five patterns including C/T allele, CC/TT, CC/CT+TT, CC+CT/TT and CC+ TT/CT genotypes to analyze respectively, including heterogeneity inspection, effect consoliating and publication bias assessment. Results A total of 11 studies were available for this analysis, including 2 443 schizophrenia patients and 2 469 controls.The Meta-analysis results showed that the allele of all people were OR=1.12,95%CI=0.96-1.31,P>0.05;CC/TT of all people were OR=1.11,95%CI=0.80-1.53,P>0.05;CC/CT+TT of all people were OR=1.13,95%CI=0.99-1.30,P>0.05;CC+CT/TT of all people were OR=1.18, 95%CI=0.93-1.50,P>0.05;CC+TT/CT of all people were OR=0.95, 95%CI=0.84-1.06,P>0.05.Conclusion Current evidence is insufficient to show that HTR2A gene T102C locus polymorphism may be associated with schizophrenia, suggesting that the gene polymorphism has no significantly genetic association with schizophrenia.

Objective To explore the association of HbA1C with microvascular complications,and to evaluate the diagnostic value of HbA1C in diabetes mellitus in high-risk populations of Guangzhou.Methods HbA1C,blood glucose,fundus photography,and microalbuminuria were detected in 208 permanent residents with high-risk factors of diabetes.The receiver operating characteristiC(ROC)curves were used to estimate the area of HbA1C,fasting plasma glucose(FPG),postprandial 2 h plasma glucose(2hPG)under the curve for discriminating microvascular complications.Results There were 14.9% adults suffering from diabetic retinopathy and 12% microalbuminuria in high risk populations of diabetes.The optimal cutoff points of HbA1C,FPG,and 2hPG in detecting retinopathy were 5.8%,7.0 mmol/L,and 10.9 mmol/L respectively.The thresholds for increasing prevalence of microalbuminuria were5.8% for HbA1C,6.4 mmol/L for FPG,and 10.7 mmol/L for 2hPG.Conclusions The prevalence of diabetic microvascular complications increases dramatically at the concentration of HbA1C 5.8%.As a diagnostic value for microvascular complications,there is no significant difference between HbA1C and 2hPG.

Objective To investigate the consensus and controversies on the delineation of radiotherapy target volume for patients with locally advanced non-small cell lung cancer (LA-NSCLC).Methods Questionnaires including 15 questions on the delineation of radiotherapy target volume of NSCLC were sent to 12 radiation departments in China in November 2015.A patient with LA-NSCLC was selected by Fudan University Shanghai Cancer Center, and simulation CT images and medical history data were sent to the 12 radiation departments.Twelve radiation oncologists from the 12 radiation departments showed and explained the delineation of radiotherapy target volume of their own, and the patient was discussed by all experts in the sixth multidisciplinary summit forum of precise radiotherapy and chemotherapy for tumor and lung cancer.Results All receivers of the questionnaire answered the questions.The standard lung window width/level for the delineation of lung cancer was 800-1600/-600 to-750 HU, and the mediastinum window was 350-400/20-40 HU.Respiratory movement was measured by stimulator, 4D-CT, and stimulator+4D-CT with 2-5 mm expansion based on experience.The primary clinical target volume (CTV) was defined as gross target volume (GTV) plus 5-6 mm for squamous carcinoma/5-8 mm for adenocarcinoma.The metastatic lesion of mediastinal lymph nodes was delineated as 5 mm plus primary lesion in 6 departments and as primary lesion in another 6 departments.Of the 12 departments, 10 applied 5 mm of set-up error, 1 applied 3 mm, and 1 applied 4-6 mm.For V20 of the lungs, 10 departments defined it as<30%, 1 as<35%, and 1 as 28%.Nine departments defined the radiation dose of concurrent chemoradiotherapy (CCRT) for LA-NSCLC as 60 Gy in 30 fractions, 62.7 Gy in 33 fractions in 1 department, 50-60 Gy in 25-30 fractions in 1 department, and 60-70 Gy in 25-30 fractions in 1 department.For the delineation of target volume for the LA-NSCLC patient treated with CCRT, the primary planning target volume (PTV) was defined as GTV plus organ movement (IGTV) and set-up error (GTV→IGTV→PTV) in 3 departments, as CTV plus organ movement (ITV) and set-up error (GTV→CTV→ITV→PTV) in 8 departments, and as CTV plus set-up error/IGTV plus 5-6 mm for squamous carcinoma/5-8 mm for adenocarcinoma (CTV) and set-up error (GTV→CTV→PTV/GTV→IGTV→CTV→PTV) in 1 department.For the delineation of PTV in the mediastinal lymph node, GTV→IGTV→PTV was performed in 3 departments, GTV→CTV→ITV→PTV in 8 departments, and GTV→CTV→PTV in 1 department.For 10%-100% patients with LA-NSCLC, the radiation field needed to be replanned when 38-50 Gy was completed.There was no unified standard for the optimal standardized uptake value (SUV) of positron emission tomography (PET)-computed tomography (CT) simulation and delineation.Seven departments had applied magnetic resonance imaging (MRI) simulation and 10 departments had applied stereotactic body radiation therapy (SBRT) for the treatment of early-stage NSCLC.For the delineation of PTV for early-stage NSCLC (T1-2N0M0), GTV→IGTV→PTV was performed in 5 departments, IGTV→PTV in 3 departments, and GTV→CTV→ITV→PTV in 2 departments.In all the 12 departments, peripheral early-stage NSCLC was given 6.0-12.5 Gy/fraction, 3-12 fractions and central early-stage NSCLC was given 4.6-10.0 Gy/fraction, 5-10 fractions.The results of discussion on the delineation of target volume for the patient were as follows:respiratory movements should be measured by 4D-CT or simulator;the lung window width/level is 1600/-600 HU and the mediastinal window width/level is 400/20 HU;the primary controversy is whether the involved-field irradiation or elective nodal irradiation should be used for the delineation of CTVnd in the mediastinal lymph node.Conclusions Basic consensus is reached for the delineation of target volume in LANSCLC in these aspects:lung window width/level, respiratory movements and set-up error, primary lesion delineation, the radiation dose in CCRT, and the optimal time for replanning the radiation field.There are controversies on the optimal SUV in the delineation of target volume based on PET-CT simulation, the optimal dose fractionation in SBRT for early-stage NSCLC, and the delineation of CTVnd.

Objective? To establish a WeChat online system supporting continued nursing care for patients receiving enteral bladder augmentation and to evaluate its effects on continued nursing care for patients with neurogenic bladder in spinal cord injury who received enteral bladder augmentation. Methods? Totally 60 patients with low-compliant neurogenic bladder in spinal cord injury who received enteral bladder augmentation and were discharged from Zhejiang Provincial People's Hospital between March 2016 and March 2018 were selected by convenient sampling, and divided into the observation group (n=30) and the control group (n=30) according to the random number table. Patients in the control group received conventional nursing care after discharge, while patients in the observation group received nursing care after discharge via the WeChat online support system. The follow-up duration was 3 months. Bladder self-management compliance, urinary catheter-associated complications, bladder function, quality of life and negative emotions at discharge and 3 months after discharge were compared between the two groups. Results? The score of bladder self-management compliance, anxiety score, depression score, and scores of physical function, role function, emotional function and social function in quality of life in the observation group were better than those in the control group 3 months after discharge (P＜0.05); the rates of urinary tract infection and urethral injury of the observation group were 3.3% and 6.7%, while those of the control group were 26.7% and 33.3%, respectively; the incidence rate of urinary catheter-associated complications of the observation group was lower than that of the control group (P＜0.05); and the parameters of bladder function such as bladder volume, bladder compliance, residual urine volume and maximum detrusor pressure of the observation group were better than those of the control group (P＜ 0.05). Conclusions? The WeChat online support system can improve patients' bladder self-management compliance, reduce the urinary catheter-associated complications, enable the recovery of bladder function, ameliorate their negative emotions, and improve their quality of life.
