Objective To study the effect of physical activities and dietary intervention on metabolic syndrome (MS) in primary school students.Methods Either one-year physical activities (PA) or dietary intervention was conducted in Grade 1-5 children from eight primary schools in Haidian district,Beijing.A ‘happy 10 minutes' program was held in the PA group,while the dietary group receiving nutrition lectures.Baseline and post-intervention data on height,weight,waist circumference,serum lipids,glucose,and blood pressure were collected.Results The prevalence of MS at baseline was 9.0％.After intervention programs were carried out,improvements on triglyceride,high density lipoprotein,fasting blood glucose,diastolic blood pressure and waist circumference in the dietary group or PA group were seen,with the dietary group showed better effects than the PA group.The prevalence of MS decreased from 10.4％ to 4.6％ in the dietary group with statistically significant difference,while it increased in both the PA group and the control group.Girls showed better effects in the dietary group.Older students showed better effects than the younger students in the PA group.In non-overweight and overweight students of the dietary intervention group,the MS related components were significantly improved.Conclusion The prevalence of metabolic syndrome was relatively high in the primary school students in Beijing.Education on nutrition could reduce the prevalence and improve the related components,which seemed to be more effective than in the PA intervention.Sex,age and nutritional status were the confounding factors for intervention programs.

Objective To investigate the prevalence of vitiligo in China through a multi-center and larse-population epidemiological survey.Methods A community-based survey was conducted in 6 cities from 6 provinces.Cluster sampling method was used.Subjects were required to fulfill the self-report questionnaires and received physical examination by dermatologists.EpiData and SPSS11.5 were utilized for statistical analysis. Results Totally,19 974 patients participated in this study,and 17 345 valid questionnaires were retrieved with a return rate of 86.84%.Of them,122 were found to have vitiligo.The prevalence and standardized prevalence of vitiligo was 0.70% and 0.56% in all patients,0.95% (75) and 0.69% in male patients and 0.50% (47) and O.45% in female patients.respectively.A significant elevation was observed in the prevalence of vitiligo in males than in females (P<0.01).The prevalence of vitiligo was increased with age and peaked in patients aging from 60 to 69 years and those over 70 years.The age at onset of vitiligo varied from 0 to 19 years in 21.85% of these patients,from 20 to 49 years in 47.05%.The most connnon type was focal vitiligo,which accounted for 36.06%,while the rarest type wag segmental type (2.46%).The pesitivity rate of family history of vitiligo was 9.84% in patients and 1.31% in community population (P<0.01).About 31.97% of the patients complained of negative influence of vitiligo on quality of life.Conclusions The standardized prevalence of vitiligo is 0.56%in 6 provinces from China.Males seem to have a higher prevalence of vifiligo than females.

Objective:To evaluate changes in the estimate glomerular filtration rate(eGFR)with aging and the risk factors.Methods:A retrospective cross-sectional study was performed based on people receiving physical examinations at the First Affiliated Hospital of Nanjing Medical University from January 2017 to January 2018.Subjects were divided into seven subgroups according to age: 18-29, 30-39, 40-49, 50-59, 60-69, 70-79, and ≥80 years old.eGFR was estimated by the Chronic Kidney Disease Epidemiology Collaboration(CKD-EPIScr)equation.Multivariate linear regression was used to analyze the correlation between eGFR and the influencing variables.The chi-square test was used to compare the incidences of eGFR<60 ml·min -1·1.73m -2in different age groups. Results:A total of 33 824 participants were included in this study.There was a negative linear eGFR-age correlation in the subjects.The mean annual rate of decline in eGFR was 0.83 ml·min -1·1.73m -2.Furthermore, the decline was steady and accelerated from the third and seventh decade onward( F=9.51, 5.37, both P=0.000). Multiple linear regression analysis showed that aging was the most prominent factor( β=-0.604, -0.534, both P=0.000), followed by serum uric acid(BUA)( β=-0.270, -0.280, both P=0.000), fasting blood-glucose(FBG)( β=-0.064, -0.046, both P=0.000), systolic blood pressure(SBP)( β=-0.015, -0.028, both P<0.05), and diastolic blood pressure(DBP)( β=-0.010, -0.026, both P<0.05). In non-elderly subjects, eGFR was found to have negative associations with body mass index(BMI)and albumin(ALB)( β=-0.028, -0.047, all P=0.000). However, in the elderly, eGFR was positively associated with ALB( β=0.022, P=0.031). eGFR showed no statistically significant correlation with BMI, TC and LDL-C.The prevalence of eGFR<60 ml·min -1·1.73m -2increased with age, at 1.55%(523/33 824)for all subjects, of whom 73.80%(386/523)were aged over 60.The incidence obviously increased from 0.22%(14/6 453)for aged 18-29 to 22.57%(214/948)for aged 80 and above( χ2=2433.71, P=0.000). Conclusions:eGFR decreases significantly with age.The incidence of eGFR<60 ml·min -1·1.73m -2in the elderly is high; eGFR is significantly correlated with BUA, FBG, SBP, DBP, and ALB in the elderly.

Objective To reduce the cancer burden in the Jinchang cohort and provide evidence for developing cancer prevention strategies and performing effectiveness evaluation in the Jinchang cohort.We are fitting thirteen years of cancer mortality data from the Jinchang cohort by using six kinds of predicting methods to compare relative fitness and to select good predicting methods for the prediction of cancer mortality trends.Methods The mortality data of cancer in Jinchnag cohort from 2001-2013 were fitted using six kinds of predicting methods:dynamic series,linear regression,exponential smoothing,autoregressive integrated moving average (ARIMA) model,grey model (GM),and Joinpoint regression.Weight coefficients of combination models were calculated by four methods:the arithmetic average method,the variance inverse method,the mean square error inverse method,and the simple weighted average method.Results The cancer mortality was fitted and compared by using six kinds of forecasting methods;the fitting precision of the Joinpoint linear regression had the highest accuracy (87.64％),followed by linear regression (87.32％),the dynamic series (86.99％),GM (1,1) (86.25％),exponential smoothing (85.72％) and ARIMA (1,0,0) (81.98％),respectively.Prediction accuracy of the combination model derived from GM (1,1) and linear regression (＞99％) was higher than that of the combination model derived from ARIMA (1,0,0) and GM (1,1).The combination model derived from the GM (1,1) and linear regression,with weight coefficients based on the arithmetic average method and the mean square error inverse method,had the best prediction effect of the four weight calculation methods.Conclusion Prediction accuracy of the combination model,with accuracy ＞95％,was higher than that of the single prediction methods.

Objective To compare the effects between felodipine plus irbesartan and felodipine plus metoprolol regimen on blood pressure and the sexual function in young and middle-aged hypertensive women. Methods In this prospective, randomized, parallelized, controlled and fixed combined therapy trial, 99 female patients(aged 18 to 60)with grade 1 and grade 2 hypertension(BP ≥ 140/90 mm Hg and ＜ 179/109 mm Hg, 1 mm Hg =0.133 kPa)were assigned to felodipine 5 mg q.d + irbesartan 150 mg q.d(F + I group, n = 49)and felodipine 5 mg q. d + metoprolol 47.5 mg q. d(F + M group, n = 50)group. Target blood pressure was ＜ 140/90 mm Hg. The female sexual function index(FSFI)questionnaire, levels of serum estradiol and testosterone were assessed. Female sexual dysfunction was defined as a FSFI score of less than 25.5. Patients were followed up for 24 weeks. Results The rate of achieving blood pressure goal between 2 groups was similar at the 4th, 8th, 12th and 24th weeks respectively (42.9% vs. 62.0% at 4th week, 89.8% vs. 90.0% at 8th week, 93.9% vs. 94.0% at 12th week,98.0% vs. 96.0% at 24th week, P ＞ 0.05). Compared to baseline, scores for the items related to"desire" and "arousal" were significantly improved(P ＜ 0.05), the level of the serum estradiol was significantly elevated[(50.3 ± 37.4)pg/L vs.(54.4 ± 10.8)pg/L before menopause,(18.4 ± 2.9)pg/L vs.(20.2 ±3.1)pg/L after menopause, P ＜0.05]and the level of the serum testosterone was significantly decreased[(722.8 ± 277.1)ng/L vs.(650.0 ± 156.0)ng/L before menopause,(841.2 ± 279.3)ng/L vs.(761.9 ± 197.8)ng/L after menopause, P ＜ 0.05]in the F + I group, while scores for the items related to" sexual desire" and "lubrication" were statistically reduced(P ＜ 0.01), the concentration of the serum estradiol was significantly reduced[(57.4 ± 9.7)pg/L vs.(51.1 ± 12.1)pg/L before menopause,(19.8±2.3)pg/L vs.(17.8 ± 3.3)pg/L after menopause, P ＜0.01]and the level of the serum testosterone was significantly increased[(775.6 ± 217.8)ng/L vs.(886.0 ± 186.4)ng/L before menopause,(812.5 ± 311.3)ng/L vs.(914.4 ± 300.2)ng/L after menopause, P＜0.01]in the F+M group. FSFI score was negatively correlated with age and systolic blood pressure levels. Conclusion felodipine plus irbesartan or metoprolol for 24 weeks equally reduced blood pressure and the former regimen is superior to the latter on sexual function improvement in this patient cohort.

Objective To investigate the role of the TNFRSF12A molecule in the pathogenesis of liver cancer.Methods Through comprehensive analysis of the Cancer Genome Atlas Program(TCGA)database and single-cell sequencing data,we studied the expression of TNFRSF12A in liver cancer and its correlation with prognosis.HPA database was utilized to analyze the subcellular localization of TNFRSF12A,and GO and KEGG analyses were performed by DAVID.TIME 2.0 was employed to analyze the correlation between TNFRSF12A and immune cell infiltration in liver cancer tissues.Results TNFRSF12A was found to be highly expressed in liver cancer tissues,significantly correlating with patient survival prognosis(OS:HR=1.61,P=0.007 0;RFS:HR=1.45,P=0.037 0;PFS:HR=1.30,P=0.099 0;DSS:HR=1.67,P=0.027 0),as well as age(P=0.046 7)and BCLC stage(P=0.045 6).TNFRSF12A co-expressed with tumor stem cell markers(CD24,SOX4,ANPEP),indicating a strong link to malignancy.Furthermore,molecular functional analysis unveiled that IL-2R primarily existed in the cell cytoplasm and played a role in processes such as cell apoptosis,invasion,and protein binding.Moreover,TNFRSF12A was associated with Treg cells and immune cell infiltration,further suggesting its role in tumor immune regulation.Conclusion TNFRSF12A exhibits a significant elevation within liver tumors and shows a notable correlation with patients'prognosis.Tumor cells engage in interactions with cytokines produced by Tregs,thereby reshaping the tumor microenvironment.The potential clinical significance of TNFRSF12A as a prognostic marker for tumors holds promise in offering novel avenues for personalized treatment and prognosis prediction.

Objective:To construct an estimating equation to accurately reflect the aging phenomenon of the glomerular filtration rate(GFR).Methods:Healthy subjects receiving physical examinations at the First Affiliated Hospital of Nanjing Medical University between January 2017 and April 2018 were included in the study, and the aging phenomenon of renal function indicators such as serum creatinine(Scr)was used as the reference standard to evaluate the accuracy of four Scr-based GFR equations during GFR aging, including the full age spectrum(FAS)equation, the Chronic Kidney Disease Epidemiology Collaboration(CKD-EPI)equation, the Osaka equation and the Xiangya equation.Results:Of 37 636 individuals receiving physical examinations, 6 534 met the criteria specified in this study.Scr, serum urea nitrogen, serum uric acid, and serum albumin showed a significant aging phenomenon( H=191.640, 196.693, 83.271, 414.585, P<0.001 for all).The GFR estimated by the four equations all decreased with aging, but the starting point and rate of decline were significantly different.The GFR aging phenomenon estimated by the FAS equation was closer to the trend of renal function indicators. Conclusions:The FAS equation may be more applicable to healthy people to understand the aging phenomenon of GFR.

OBJECTIVE: Clozapine is one of the most commonly used antipsychotic drugs in China. To date, few studies have investigated the patterns the prescription of clozapine nationwide. The present study examined these patterns in China in 2006 and identified the demographic and clinical characteristics associated with the use of clozapine. METHODS: Using a standardized protocol and data collection procedure, we surveyed 5,898 patients with schizophrenia in 10 provinces with differing levels of economic development. RESULTS: Overall, clozapine had been prescribed for 31.9% (n=1,883) of the patients; however we found considerable variation among the 10 provinces. The frequency of clozapine use was highest in Sichuan (39.3%) and lowest in Beijing (17.3%). The mean daily dose of clozapine was 210.36+/-128.72 mg/day, and 25.1% of the patients were treated with clozapine in combination with other antipsychotics. Compared with the group not receiving clozapine, clozapine-user had been treated for longer durations and had experienced a greater number of relapses and hospitalizations. Furthermore, those in the clozapine-user had lower family incomes, were less able to seek psychiatric services, and more likely to be male and have a positive family history of schizophrenia. A multiple logistic regression analysis revealed that age, sex, professional help-seeking behaviors, duration of illness, economic status, educational level, and clinical manifestations were associated with the use of clozapine. CONCLUSION: Clozapine use is common in China. However, use of the antipsychotic varies among provinces, and demographic and clinical factors play important roles in the prescription of clozapine.

OBJECTIVETo evaluate the feasibility of autologous peripheral CD(34)(+) cell transplantation for the treatment of severe autoimmune disease.

METHODSTen patients received mobilized and purified CD(34)(+) cells transplantation. The mobilization regimen was CTX plus rhG-CSF and the CD(34)(+) cells were selected by CliniMACS. (1.98 +/- 0.95) x 10(8) CD(34)(+) cells were obtained. The purity of CD(34)(+) cells was (91.4 +/- 10.6)% and the recovering rate was (60.5 +/- 19.8)%. The conditioning regimens were CTX (200 mg/kg) plus ATG (90 mg/kg) or CTX (150 mg/kg) plus TBI (4 - 6 Gy). (2.14 +/- 1.05) x 10(6)/kg CD(34)(+) cells were infused. The time of ANC >or= 0.5 x 10(9)/L was 8.6 +/- 2.5 days, and platelet >or= 20 x 10(9)/L was 9.0 +/- 5.2 days. After the hematopoietic recovery, the levels of CD(3)(+) T cell, CD(19)(+) B cells and CD(16)(+)CD(56)(+) NK cells were all below that of pre-transplantation. The main transplant-related complication was CMV infection. The transplant-related mortality was 2/10. All patients who survived showed improvement of the disease with DAI score decreasing from 17 to 4 in systemic lupus erythematosus patients, DAS 28 score from 6.4 to 1.8 in rheumatoid arthritis patients.

CONCLUSIONThe result suggests that autologous peripheral CD(34)(+) cell transplantation is an alternative choice for the treatment of severe autoimmune disease. The short-term outcome is satisfying.

OBJECTIVE: To investigate the patterns of antipsychotic use in China and to analyze the factors that influence antipsychotic prescriptions. METHODS: A standardized survey was conducted from May 20 to 24 2002 in five different regions of China with varying economic levels. The patterns of antipsychotic medication use were analyzed in a sample of 4,779 patients with schizophrenia. The survey gathered information on demographic characteristics, clinical profiles, and antipsychotic medications prescribed. Multiple logistic regression was used to analyze factors related to patterns of antipsychotic medication use. RESULTS: A plurality of patients with schizophrenia was treated with clozapine (39%); this was followed by risperidone, sulpride, chlorpromazine, perphenazine, and haloperidol. More than 56.3% of patients were treated with only one atypical antipsychotic. The mean daily dose of chlorpromazine was 365+/-253 mg (mean+/-standard deviation), and 6.5% of patients were treated with depot injections of typical antipsychotic medications. A total of 73.7% (n=3,523) of patients with schizophrenia received monotherapy, 24.8% (n=1,183) received two antipsychotics, 1.1% (n=52) received three antipsychotics, and one received four different antipsychotics. Patients often simultaneously received other classes of medications including anticholinergic agents, benzodiazepines, beta-blockers, antidepressants, and mood stabilizers. Economic status and clinical symptoms were the main factors that contributed to the patterns of antipsychotic prescription. CONCLUSION: The present study suggests that atypical antipsychotic medications, especially clozapine, are the primary psychiatric treatments of choice in the management of schizophrenia in China. Moreover, the economic status and clinical profile of the patient are the major factors affecting the prescription of antipsychotic medication.
