Objective: To investigate the prevalence of hypertension, diabetes and hyperlipidemia among HIV/AIDS patients aged 50 years and above receiving antiretroviral therapy (ART) in Wuxi City, Jiangsu Province, so as to provide insights into the prevention and intervention of chronic diseases for these populations. Methods: The HIV/AIDS patients aged 50 years and above receiving ART were recruited at designated HIV/AIDS medical institutions in Wuxi City using the convenient sampling method from March to June 2024. Demographic information, treatment status and self-reported prevalence of hypertension, diabetes and hyperlipidemia were collected through questionnaire surveys. Factors affecting the prevalence of chronic diseases were analyzed using a multivariable logistic regression model. Results: A total of 830 HIV/AIDS patients receiving ART were surveyed, including 656 males (79.04%) and 375 patients aged 50 to <60 years (45.18%). Among them, 366 patients reported having at least one type of chronic disease, including hypertension, diabetes and hyperlipidemia, with a self-reported prevalence rate of 44.10%. Specifically, 280, 114 and 61 patients reported having hypertension, diabetes and hyperlipidemia, with the self-reported prevalence rates of 33.73%, 13.73% and 7.35%, respectively. Multivariable logistic regression analysis showed that male patients (OR=1.725, 95%CI: 1.187-2.507), those with monthly income less than 3 000 yuan (OR=1.521, 95%CI: 1.122-2.063), those with body mass index of 24 kg/m2 and above (OR=1.577, 95%CI: 1.168-2.130), those who initiated ART at ages of 50 years and above (50 to <60 years, OR=1.535, 95%CI: 1.052-2.238; ≥60 years, OR=3.322, 95%CI: 2.191-5.038), those with ART duration of 10 years and above (OR=2.069, 95%CI: 1.419-3.017), and those who received non-first-line regimens (OR=1.776, 95%CI: 1.304-2.418) had higher risks of developing at least one type of chronic disease, including hypertension, diabetes and hyperlipidemia. Conclusions The self-reported prevalence of at least one type of chronic disease, including hypertension, diabetes and hyperlipidemia among HIV/AIDS patients aged 50 years and above receiving ART in Wuxi City was 44.10%. Gender, monthly income, body mass index and ART status are the main influencing factors for the risk of chronic diseases.

Objective To analyze the transcriptome sequencing results of Nelson Bay virus(NBV)-infected murine RAW264.7 mac-rophages,and to screen for differentially expressed genes(DEGs)to provide a theoretical basis for exploring the mechanism of innate immune response in reovirus infection.Methods RAW264.7 cells were infected with the NBV-Miyazaki virus strain at a multiplicity of infection(MOI)of 30.We used transcriptome sequencing technologies,with q＜0.05 and|log2FC|≥ 1,for screening the DEGs in the infection and control groups.The Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)databases were used for enrichment analysis of DEGs.Results A total of 442 genes were differentially expressed in the infection group,of which 381 genes were significantly upregulated and 61 genes were significantly downregulated.In the GO analysis,the enrichment of DEGs was primarily related to the innate immune response,defense response to viruses,cytokine production,and cell response to cytokine stimulation.In the KEGG analysis,the enrichment of DEGs were primarily related to the Toll-like receptor,retinoid acid inducible gene Ⅰ-like receptor,PI3K/Akt,and other signaling pathways.Conclusion RAW264.7 macrophages infected with the NBV-Miyazaki virus can activate pattern recognition receptors;promote the release of cytokines,chemokines,and other immune-related factors;and enhance antibody-dependent cell-mediated cytotoxicity to exert an immune effect.This study provides a theoretical basis for exploring the mechanisms of innate immu-nity during NBV-Miyazaki virus infection.

Objective:To understand the uptake of post-exposure prophylaxis (PEP) and related factors among male sex workers (MSW) and provide references for the promotion of PEP.Methods:A cross-sectional study was conducted using convenience sampling to recruit MSW participants with the help of a community-based organization in October 2023, in Wuxi City, Jiangsu Province. The sample size was estimated at 340 people. A self-administered questionnaire was used to collect their social demographic characteristics, sexual behaviors, knowledge, beliefs, and uptake of PEP. A logistic regression model was used to analyze factors associated with the uptake of PEP in MSW. The SPSS 26.0 software was used for statistical analysis.Results:A total of 357 participants were recruited, mainly aged 18-20 (55.7%,199/357), unmarried (94.4%,337/357), and having an education background of junior high school or below (50.1%,179/357). Among 357 participants, 64.4% (230/357) knew about PEP, 51.0% (182/357) believed in the efficacy of PEP, and 13.4% (48/357) had experience of using PEP. Among 68 respondents having high-risk sexual behaviors in the past 3 months, 17.6% (12/68) have had uptake of PEP. Multivariable logistic regression analysis showed that group sex with men in the past 3 months (a OR=7.51, 95% CI: 1.37-41.09), HIV testing in the past 3 months (a OR=2.89, 95% CI: 1.16-7.16), the experience of using pre-exposure prophylaxis (a OR=30.18,95% CI: 12.60-72.24) and believing in the efficacy of PEP (a OR=2.94, 95% CI: 1.04-8.29) were the associated factors with the uptake of PEP in MSW. Conclusions:Although the overall uptake rate of PEP in MSW was high, the proportion of using PEP was still low among participants having high-risk sexual behaviors in the past 3 months. Therefore, it is necessary to strengthen HIV risk awareness education considering their characteristics and promote timely uptake of PEP to interrupt HIV transmission.

Anthropometric indexes play a crucial role in identifying obesity. However, as an internationally commonly used indicator of obesity diagnosis, BMI has limitations in distinguishing lean body mass from fat mass. The weight-adjusted waist index (WWI), a novel anthropometric index, assesses adiposity through standardized waist circumference for weight, which presents an excellent capacity to predict the morbidity and mortality risks of various diseases. However, research on WWI is still in the exploratory stage, and there is a lack of unified standards for using this indicator to determine obesity. In addition, its potential application in children and adolescents also urgently needs to be explored. Therefore, this article comprehensively summarizes and compares the distinctive characteristics between WWI and other obesity-related anthropometric indexes. Bibliometric methods are used to analyze the hotspots and trends of WWI-related research, and we focus on discussing the value of WWI in predicting adverse health outcomes, including cardiovascular disease, diabetes, liver and kidney diseases. We aim to promote the application of WWI in a broader field and fully demonstrate its important public health significance and broad application prospects.

Objective: To understand the relationships between video time, exercise time and the mental sub-health of Chinese adolescents, and to assist the development of Chinese adolescents’ mental health. Methods: In this study, 16 545 adolescents aged 13-22 years in six administrative regions of China were surveyed using an adolescent sub-health multi-dimensional assessment questionnaire (MSQA), and daily physical exercise time, video screen time and other indicators were recorded. Binary Logistic regression analysis was used to understand adolescents’ mental sub-health and the correlation between video time and exercise time. Results: Detection rate of mental sub-health status in adolescents with video time ≤2 h/d was lower than that of adolescents with video time >2 h/d(19.1%，22.1%), and the detection rate of adolescents with exercise time ≤60 min/d(22.1%，17.7%) was higher than that of adolescents with exercise time >60 min/d. These differences were statistically significant (χ2=14.47, 6.97, P<0.05). Binary Logistic regression analysis showed that the risk of mental sub-health status for Chinese adolescents whose screen time was more than 2 h/d was 1.20 times that of those with screen time ≤2 h/d, and the difference was statistically significant (P<0.01). The risk of mental sub-health for students whose exercise time was > 60 min/d was 0.86 times that of students who exercised ≤ 60 min/d, and the difference was statistically significant (P<0.05). Conclusion Screen time >2 h/d and exercise time <60 min/d were negative factors leading to mental sub-health symptoms in Chinese adolescents.It is proposed to jointly promote the healthy adolescent development through health education,as well as positive family and social environment.

Objective: To understand the results of tuberculin skin test (PPD) in preschool children after the vaccination of BCG, and to analyze the effect of BCG vaccination on latent tuberculosis infection in children. Methods: From January to November 2018, a total of 1 359 preschool children from 14 kindergartens in 8 districts and cities of Jiangsu Province were selected for tuberculin test(PPD), and chest X-ray examination was performed on children with strong PPD results. Results: The positive rate of PPD in preschool children in Jiangsu Province was 23.33%, of which strong positive and moderate positive (PPD≥10 mm) were totaled 6.47%. There were 149 boys (21.29%) with PPD positive reactions and 168 girls(25.50%) with PPD positive reactions, and differences of PPD positive reactions with different genders were of no statistical significance (χ2=3.36, P>0.05) And there were 201 children (25.35%) with PPD positive reactions in northern Jiangsu, 116 children (20.50%) with PPD positive reactions in southern Jiangsu. There were significant differences in the results of PPD positive and negative reactions between different regions(χ2=4.35, P<0.05). There was 1 case of PPD positive reactions among 3-year-old children(0.71%), 19 cases among 4-year-old children(3.89%), 31 cases among 5-year-old children(8.96%), and 37 cases among 6-year-old children(9.63%), and the differences of PPD positive reactions of different age groups were of statistical significance(χ2=21.69, P<0.01). Conclusion The positive rate of PPD in preschool children in Jiangsu Province is very low, indicating that PPD can be used as a detection method for latent infection in children. The overall positive rate of PPD in preschool children in Jiangsu Province is also low, and appropriate measures should be taken to protect susceptible children and effectively prevent and control childhood tuberculosis.

Objective To explore the method and efficacy of home enteral nutrition for patients undergoing radical resection of esophagus cancer. Methods A total of 85 patients who underwent radical surgery for esophageal cancer and jejunum fistula from January 2016 to March 2017 were enrolled and were divided into observation group (n=44) and control group (n=41) by random number table method. Patients of control group took normal family diet orally after nutrition assessment and jejunum fistula clipped while patients of observation group received extra special immune enteral nutrition preparations for tumor through fistula of jejunostomy under the guidance of a nutrition support team. After one month treatment, plasma nutrition indicators and European Screening for Nutrition Risk (NRS 2002) assessment were performed to analyze the difference of two groups to compare the nutrition status. Results All indicators did not differ when discharged for two groups (P>0.05). After one month intervation, level of hemoglobin, total serum protein, albumin, prealbumin and transferrin of the observation group were statistically higher than those of control group [(12.90±1.33) vs. (10.83±1.35)g/dl, (72.22±4.83) vs. (63.90±5.44)g/L, (41.63±2.67) vs. (36.98±3.69)g/L,(217.70±56.72) vs. (166.27±39.97)mg/L,(2.41±0.38) vs. (1.76±0.47)g/L; P< 0.01]. Percentage of patients with high nutritional risk (NRS 2002 ≥3) in the observation group was lower than that of the control group (45.5% vs. 68.3%; P<0.05). Conclusions Nutritional support at home after discharge could improve the nutritional status and reduce the risk of malnutrition for patients who underwent radical surgery for esophageal cancer.

AIM:To compare the effects of atorvastatin at different doses on the function of endothelial proge-nitor cells (EPCs) in the patients with ST-segment elevation myocardial infarction (STEMI).METHODS:The patients of STEMI (n=40) were chosen.According to treatment with different doses of atorvastatin calcium tablet, they were randomly divided into a group of 20 mg and a group of 40 mg (20 cases in each group).The EPCs isolated from the patients were identified and quantitatively analyzed at different time points (before the treatment and on days 5, 10, 15, 20, 30, 60, 90 and 120 after the treatment) by flow cytometry.The surface markers of the EPCs, CXC chemokine receptor 4 (CXCR4), vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF) and silent information regulator 1 (SIRT1), were also detected.RESULTS:On the 5th day, the group of 40 mg demonstrated stronger cell proliferation capability and higher expression levels of CXCR4, VEGF and bFGF than the group of 20 mg (P<0.05).From the 10th day to 120th day, the group of 20 mg revealed stronger cell proliferation capability and higher expression levels of CXCR4, VEGF and bFGF than the group of 40 mg (P<0.05).Within 30 d, the expression of SIRT1 showed no significant diffe-rence between the 2 groups, yet it witnessed a marked change after that and peaked on the 60th day with a drop afterwards.At each time point, the SIRT1 expression level in the group 20 mg was observed higher than that in the group of 40 mg (P<0.05).CONCLUSION:In the acute phase, the repair function of the body treated with atorvastatin at dose of 40 mg is better than that with 20 mg.However, in a long term the low concentration of statin therapy works better in improving the vascular intima and promoting the angiogenesis than high concentration.

Objective To investigate the changes of A20 expression stimulated by free fatty acids (FFA) and its pathway.Methods HepG2 cells and U937 cells were stimulated by 0.5 mmol/L mixed FFA.The expression of A20,phosphor-p65 and phosphor-IκBα of neclear factor (NF)-κB pathway and phosphor-c-Jun N-terminal kinase (JNK),JNK,phosphor-extracellular signal-regulated kinase (ERK),ERK,phosphor-p38 and p38 of mitogen-activated protein kinase (MAPK) pathway were detected by Western blotting.The level of interleukin (IL)-12p,IL-1β,tumor necrosis factor (TNF)-α,IL-6,IL-10 and IL-8 cytokines in the supernatant of cell culture were detected by flow cytometry.T-test was performed for statistical analysis.Results The level of A20 changed along with the stimulated time of FFA.NF-κB and MAPK pathways were activated after FFA stimulation.The secretion of IL-6 and IL-8 increased after HepG2 cells stimulated by FFA and both reached peak at 24 hour.Compared with control group,the difference in IL-8 was statistically significant ((423.8 ± 8.9) pg/mL vs (12.4 ± 4.5) pg/mL,t=41.28,P＜0.01).The difference in IL-6 was also statistically significant ((4 082±423.6) pg/mL vs (52.9±29.5) pg/mL,t=9.49,P＜0.01).After U937 cells were stimulated by FFA,the secretion of IL-8 increased compared with control group.And in a certain period of time the secretion was time dependence.The maximum secretion of 24 hours was (200.6±5.7) pg/mL vs (5.0±3.9) pg/mL,and the difference was statistically significant (t=28.16,P＜0.01).IL-10,IL-12p,IL-1β and TNF-α were detected.Both NF-κB pathway and MAPK pathway were detected.Conclusions The in vitro FFA mediated steatotic cell model could induce the expression change of A20 and secretion of inflammatory cytokines.NF-κB and MAPK pathways involved in the response to FFA in HepG2 cells and U937 cells.
