ABSTRACT
Objective@#To establish a hypertension risk assessment model among the middle-aged and elderly populations based on residents' electronic healthcare records of the basic public health service program, so as to provide insights into prevention of hypertension.@*Methods@#Demographic features and physical examinations were collected among residents at ages of 40 years and older from residents' electronic healthcare records of the basic public health service program in a county of Zhejiang Province from 2019 to 2020. The risk factors of hypertension were identified using a multivariable logistic regression model, and the odds ratio (OR) for each risk factor was transformed into approximate relative risk (RR), which was included in the formula for calculation of the disease risk proposed by Harvard School of Public Health to create a hypertension risk assessment model. The predictive value of the model was evaluated using a receiver operator characteristic (ROC) curve.@*Results@#Totally 7 275 subjects were enrolled, with a mean age of (66.15±7.91) years, and the participants included 3 189 males and 4 086 females, with a male-to-female ratio of 0.78∶1. There were 190 cases with new-onset hypertension (2.61%). Multivariable logistic regression analysis revealed that overweight, obesity, central obesity, borderline high triacylglycerol (TG), elevated TG, abnormal fasting plasma glucose (FPG), prehypertension and family history of hypertension were included in the hypertension risk assessment model, with approximate RR values of 1.66, 1.96, 1.54, 1.17, 1.64, 1.45, 1.69 and 1.11. The area under the ROC curve (AUC) of the model was 0.678 (95%CI: 0.641-0.715, P<0.001), and the optimal positive cut-off was 0.899. The model predicted 139 subjects with RR>0.899 for hypertension, with a sensitivity of 73.16% and specificity of 55.79%.@*Conclusions@#The hypertension risk assessment model created in this study is feasible to predict the RR for developing hypertension among the middle-aged and elderly populations, which has a predictive value in healthcare management.
ABSTRACT
Objective@#To understand the incidence of school violence and its related factors among senior students in rural primary schools in Guizhou and Anhui provinces in 2016.@*Methods@#From September to November 2016, one county was randomly selected from 47 impoverished counties of Guizhou and one county was randomly selected from 18 impoverished counties of Anhui Province by using multi-stage cluster sampling method. A total of 4 schools were randomly selected from primary schools which had more than 70% students with rural resident registration in each selected county, and 3 classes were randomly selected from fifth and sixth grades of each selected school. All students in each selected class were included in this study. A total of 2 521 students were included, and 2 506 valid questionnaires were collected with an effective response rate about 99.4%. Self-designed questionnaires were used to collect data on individual information, family information, and the incidence of school violence with related factors. Multivariable logistic regression was conducted to analyze related factors of school violence.@*Results@#The incidence of violence in rural primary schools was 50.4% (1 264/2 506) in 2016. The number of students who had physical assault, fought or been bullied was 682 (27.2%), 689 (27.5%) and 764 (30.5%), respectively. The results of multivariable logistic regression showed that the OR (95%CI) values of incidence of school violence for male students was 2.13(1.78-2.54) compared with female students; and the OR(95%CI) values of incidence of school violence for students with high peer acceptance, high family intimacy, more physical activity and mother who had education background of junior high school, senior high school, technical secondary school and junior college, bachelor′s degree or above were 0.39 (0.26-0.57), 0.47 (0.40-0.57), 0.64 (0.52-0.78), 0.79 (0.66-0.96), and 0.65 (0.46-0.92) compared with those with low peer acceptance, low family intimacy, less physical activity and mother who had primary education and below.@*Conclusion@#The incidence of violence in rural primary schools is not optimistic. Gender, peer acceptance, family intimacy, physical activity and mother education are related to school violence.
ABSTRACT
Objective To investigate the role of transient receptor potential vanilloid tpye 1 (TRPV1) in the pathological process of detrusor overactivity (DO) induced by partial bladder outlet obstruction (BOO).Methods Between June 2014 and December 2014,40 female Wistar rats received partial urethral ligation and urodynamic analysis 6 weeks after.Urinary bladder and dorsal root ganglion (DRG) were removed and RT-PCR,Western Blot and IHC were performed to investigate the expression and location of TRPV1 in control and DO rats.Effect of different concentrations of TRPV1 agonist,as well as TRPV1 antagonist,was also evaluated with isolated detrusor strips.Results 40 female Wistar rats received BOO surgery and 26 of them developed DO.Immunohistochemistry observed linear TRPV1-reactive staining mainly in sub-urothelial and muscular layer.Expression of TRPV1 mRNA and protein in urinary bladder [(0.18±0.02) vs.(0.36 ±0.03),P<0.05] and dorsal root ganglia (DRG) [(0.41 ±0.05) vs.(0.66 ±0.04),P < 0.05] significantly increased in BOO induced OAB rats.In isolated detrusor strips studies,the amplitude [(0.26 ±0.05)g vs.(0.69 ±0.11)g,P <0.05] and frequency [(5.91 ±0.59) Hz vs.(8.75 ± 0.54) Hz,P < 0.05] of contractions of DO tissues were significantly higher than that of control ones.Capsaicin significantly increased the amplitude but not frequency of detrusor intrinsic contractility and this effect was enhanced in OAB conditions.All changes induced by capsaicin were blocked by capsazepine pre-incubated.Conclusions In BOO induced DO rats,over-expressed TRPV1 was involved in DO pathological process by directly sensitizing bladder afferent fibers or indirectly enhancing detrusor intrinsic properties.
ABSTRACT
OBJECTIVE:To evaluated the utilization of antineoplastics for intravenous use in our hospital and to provide references for clinical medication and pharmacoeconomic research. METHODS:The utilization of antineoplastics in our hospital from 2007 to 2009 was statistically analyzed in respect of consumption sum and DDDs. RESULTS:Amount and consumption sum of antineoplastics in our hospital increased rapidly in recent 3 years. The DDDs of drug were markedly different from their consumption sum rank,for example Docetaxel injection. Antineoplastics for intravenous use sourcing from plants took up big proportion of antineoplastics and they accounted for 50% of the top 10 antineoplastics in the list of consumption sum. CONCLUSION:The antineoplastics for intravenous use in our hospital basically remain stable in category and develop rapidly in recent years,which focus on reasonable price,exact therapeutic effect and less adverse reaction.

Methods HPLC was used to measure the content of arctinin, and the adsorption performance and the elution parameters were investigated. Results The optimal separation conditions were as follows: the concentration of Arctinin was 5.5 mg/ml with a flow rate of 2 BV/h, and 50% alcohol was used as eluant. The adsorption of Arctinin was 52.08 mg/g, and the elution ratio of arctinin was 93.8%, and the purity of arctinin reached 65.2%. Conclusion AB-8 resin can be used to refine the arctinin in the extraction of Fructus arctii.
