Follow-up of people living with HIV/AIDS by primary health care institutions in rural area of Jiangxi province / 中华流行病学杂志

Objective@#To understand the current status of follow up of people living with HIV/AIDS by health service at grass root in rural area of Jiangxi province and related factors, and provide references for the promotion of the follow up by grass root health service.@*Methods@#People living HIV/AIDS aged ≥18 years and diagnosed before 31 December 2017 in 6 townships of Xinjian, Yushan counties and Guixi city were included in the study in Jiangxi province. They had been followed up for more than one time after the first epidemiologic survey. The information about their demographic characteristics and HIV infection status were collected by using self-designed questionnaire. Univariate and multivariate logistic regression analyses were conducted to identify the factors that influencing the acceptance of follow up by grass root health service.@*Results@#Of the 373 surveyed HIV infected subjects aged (53.06±16.15) years, 261 were males (70.0%, 261/373). Among the surveyed subjects, the illiteracy and people who received only primary school education accounted for 54.7% (204/373). The rate of follow up of the HIV infected subjects by grass root health service was 55.8% (208/373), and those through heterosexual contact were 58.5% (190/325). The multivariate regression analysis showed that the acceptance of follow up by grass root health service was higher in those who were farmers (OR=7.36, 95%CI: 2.52-21.45), had family support (OR=16.01, 95%CI: 2.25-49.73), didn’t worry about discrimination (OR=12.97, 95%CI: 4.75-35.42), trusted health care provider (OR=5.07, 95%CI: 2.19-11.76) and showed AIDS symptoms (OR=10.58, 95%CI: 2.25- 49.73).@*Conclusions@#The performance of follow up of people living with HIV/AIDS by grass root health service was well, suggesting it is a feasible management model. Being famer or not, family member supporting or not, worry about discrimination or not, trusting health care provider or not and showing AIDS symptoms or not were the main factors influencing the acceptance of follow up by grass root health service.

Cognitive map study of type 2 diabetic nephropathy based on BP neural network model / 中华内分泌代谢杂志

Objective A BP neural network model for diagnosing type 2 diabetic nephropathy based on laboratory tests was developed and evaluated. Methods Patients with type 2 diabetic nephropathy from 5 hospitals of Chongqing,Guizhou and Sichuan Provinces from January 2016 to December 2016 were collected in the study. Totally 89 parameters were analyzed by univariate analysis to identify significant variables by SPSS 19. 0 and MATLAB 2014a. The diagnostic performance of the two methods were compared. Results A total of 477 patients with type 2 diabetic nephropathy and 449 patients of control group were included. Univariate analysis showed that 42 variables had significant difference. Logistic regression analysis showed that 12 variables were included in the optimal regression equation. This BP neural network had 42 input layer nodes,15 hidden layer nodes and 1 output layer nodes. The Youden index of logistic regression analysis and BP neural network(training set and test set) were 0.76,0.89 and 0.83. The accurately diagnosed were 88.12%,94.24%,and 91.34%,the AUC were 0.95,0.98,and 0.96. Conclusion A BP neural network model was developed,which has important accessory diagnostic value for diagnosis of type 2 diabetic nephropathy. But all these conclusions need further validation in clinic.

@#Objective To observe the effect of homemade ankle-foot orthopedic band on motor function of lower extremities in children with foot drop post spastic hemiplegic cerebral palsy (CP). Methods 24 spastic hemiplegic CP children were randomly divided into observation group (n=12) and control group (n=12). Both groups accepted roution rehabilitation training. The control group accepted walking training, and the observation group accepted walking training wearing the homemade ankle-foot orthopedic band, for 12 weeks. They were assessed with modified Ashworth Scale (MAS) of gastrocnemius, range of motion (ROM) of ankle active dorsiflexion, and D and E domains of Gross Motor Function Measure (GMFM-88) before and after treatment. Results The score of MAS significantly decreased in both groups after treatment (P<0.01), and decreased more in the observation group than in the control group (P<0.05).

Effects of interferon-?, tumor necrosis factor-? and interleukin-1? on apoptosis of human airway smooth muscle cells in vitro / 中国病理生理杂志

AIM:To clarify if interferon-?(IFN-?), tumor necrosis factor-?(TNF-?)and interleukin-1?(IL-1?)can induce apoptosis of human airway smooth muscle cells (ASMCs) in vitro. METHODS: Human ASMCs were isolated and cultured in DMEM containing 10% fetal bovine serum. Passage 4-6 cell was used in the experiment. IFN-?,TNF-? and IL-1?, were used separately or together in the treatment of human ASMCs. The effects of IFN-?,TNF-? and IL-1? on the growth of the cells was detected by MTT method at the hour 0,24,48 and 72. Light microscopy and electron microscopy were used to examine the morphological change. DNA fragmentation was analyzed by agarose gel electrophoresis. SP immunohistological staing method was performed to detect the change of expressions of p53 , bcl-2 and bax gene. The apoptosis cell percentage were detected by in situ end labeling technique (TUNEL)of fragmental DNA. RESULTS: (1)IFN-? or IFN-? together with TNF-? and IL-1? decreased the number of viable cells in a time dependent manner. (2) Light and electron microscopic examination showed cell shrinkage, membrane blebbing, nuclear contraction, chromatin condensation and nuclear fragmentation in human ASMCs. (3) Agarose gel electrophoresis showed a characteristic"ladder"of DNA bands representing integer multiples of the internucleosomal fragments (about 180-200 bp) in cytokine cotreated human ASMCs. (4)The expression of p53 and bax gene in cytokine cotreated group was significantly higher than in control group, but the expression of bcl-2 gene was lower than in control group. (5)Stimultaneous treatment with IFN-?(4?10 5 U/L),TNF-?(4?10 5 U/L)and /or IL-1? (10?10 4 U/L) induced apoptosis of human ASMCs. Apoptotic index of human ASMCs in cytokine co-treated group was significantly higher than in control group ( P
