Objective:To describe the prevalence of non-alcoholic fatty liver disease (NAFLD) in people living with HIV in Taizhou, Zhejiang Province, and identify the factors associated with NAFLD in this population.Methods:A cross-sectional survey was conducted from 2021 to 2023. Based on the routine follow-up management of people living with HIV, liver ultrasound examination, physical examination and laboratory test were conducted to collect the information about the diagnosis of NAFLD and biochemical indicators in this population. Logistic regression model was used to identify the factors associated with the prevalence of NAFLD.Results:In the 2 550 study participants, the prevalence of NAFLD was 21.5% (548/2 550), abnormal liver function was found in 23.7% (604/2 550) of the study participants, and liver fibrosis was found in 45.2% (1 152/2 550) of the study participants. Multivariable logistic regression analyses showed that being women (a OR=0.55, 95% CI: 0.42-0.73), being overweight or obese (a OR=3.22, 95% CI: 2.59-4.01), having diabetes (a OR=3.37, 95% CI: 2.15-5.29), having dyslipidemia (a OR=2.96, 95% CI: 2.25-3.89), CD4 + T lymphocyte (CD4) counts <200 cells/μl (a OR=0.61, 95% CI: 0.42-0.88), and receiving Efavirenz (EFV) + Lamivudine (3TC) + Zidovudine (AZT) for antiretroviral therapy (ART)(a OR=1.52, 95% CI: 1.17-1.98) were associated with NAFLD. NAFLD was positively associated with abnormal liver function (a OR=2.01, 95% CI: 1.60-2.52) and inversely associated with liver fibrosis (a OR=0.76, 95% CI: 0.59-0.98). The 45-59 age group (a OR=7.05, 95% CI: 5.65-8.80), CD4 counts <200 cells/μl (a OR=1.45, 95% CI: 1.06-1.97) and receiving Nevirapine (NVP)+3TC+AZT of ART (a OR=1.87,95% CI: 1.44-2.43) were the main factors associated with liver fibrosis. Conclusions:The prevalence of NAFLD in people living with HIV Taizhou was more than 20.0%, with a significant proportion of them having abnormal liver function and liver fibrosis. Being overweight or obese, suffering from diabetes, having dyslipidemia, low CD4 counts, and receiving specific ART were associated with NAFLD. NAFLD, CD4 counts and specific ART were the main factors associated with abnormal liver function and liver fibrosis.

Objective:To investigate the life expectancy of antiretroviral treatment (ART) HIV-infected patients and its trends in Taizhou City, Zhejiang Province from 2014 to 2023.Methods:The data were obtained from the China Information System for Disease Control and Prevention , and the study subjects were HIV-infected patients received ART in Taizhou City. An abbreviated life expectancy table was prepared based on Chiang's method to analyze the differences in life expectancy of HIV-infected patients receiving ART in Taizhou City with different characteristics in 2023 and to compare the trends in life expectancy of patients with different CD4 +T lymphocytes (CD4) counts at the time of initiation of ART from 2014 to 2023. Results:A total of 4 825 patients were enrolled in this study, with a cumulative follow-up of 276 648.56 person-years, and a case-fatality rate of 18.07 (95% CI: 16.48-19.65) /1 000 person-years. In 2023, male patients had lower life expectancy than females in all age groups, and those who were married had higher life expectancy than those who were unmarried and those who were divorced or widowed; patients who had been transmitted heterosexually had lower life expectancy than those who had been transmitted through homosexual transmission. Patients with different CD4 counts at the time of initiating ART had different life expectancies in all age groups. The life expectancy of patients with CD4 counts ≥350 cells/μl when initiating the treatment was higher than that of patients with CD4 counts <200 cells/μl in all age groups. The life expectancy of HIV-infected patients on ART at age 20 and 50 increased from 39.0 years and 19.1 years in 2014 to 46.0 years and 24.1 years in 2023, respectively, with an average annual percentage change of 2.43% (95% CI: 0.81%-4.07%) and 3.34% (95% CI: 1.17%-5.56%). The change in life expectancy was similar for patients with CD4 counts ≥350 cells/μl and 200-349 cells/μl at the time of initiating treatment in 2016-2023, and was higher than that for patients with CD4 counts <200 cells/μl. The rate of increase in life expectancy for patients at age 50 was higher than that at age 20 for all CD4 counts. Conclusions:The rising trend of life expectancy among HIV-infected patients on ART in Taizhou City is obvious. But the disparity between patients with different characteristics is obvious, especially among patients with baseline CD4 counts <200 cells/μl, suggesting the importance of expanded testing, early diagnosis and timely initiation of ART to improve the life expectancy of HIV-infected patients.

Objective: To explore the prevalence of elevated blood pressure and overweight/obesity and their comorbidities among Tibetan middle school students in Lhasa, and to analyze their association with lifestyle and other factors, so as to provide a basis for the intervention measures targeting elevated blood pressure, overweight and obesity among middle school students in high altitude area. Methods: Using a stratified cluster random sampling method in September 2021, a total of 1 488 Tibetan junior and high students from Lhasa City were investigated with blood pressure measurement, physical examination and questionnaire survey. The influencing factors of elevated blood pressure, overweight and obesity and their comorbidities association were analyzed by multivariate Logistic regression. Results: The prevalence of elevated blood pressure, overweight/obesity and their comorbidities were 17.8%, 17.4% , 5.0% respectively. Multivariate Logistic regression analysis showed that age( OR =0.81), residence, body mass inex(BMI) and gender were the influencing factors of elevated blood pressure; and the risks of elevated blood pressure in female students were higher than male students ( OR =1.89), suburban students were higher than urban students ( OR =8.06), overweight and obesity groups were higher than normal groups ( OR =2.55, 2.87) ( P <0.05). Adjusting for confounding factors such as gender, residence and school, and BMI (only for elevated blood pressure), daily screen time ≥2 h was positively correlated with elevated blood pressure, overweight/obesity and its comorbidities ( OR =1.56, 1.59 , 2.51) ( P <0.05). Conclusions The prevalence of elevated blood pressure, overweight/obesity are relatively high in Lhasa. Longer screen time is a common factor affecting with elevated blood pressure, overweight/obesity and comorbidities among Tibetan students. Measures should be taken intervene in the lifestyle of Tibetan students, in order to reduce elevated blood pressure and overweight/obesity.

Objective:To explore the mechanism of kidney-protecting spirit pill for the treatment of diabetic nephropathy(DN)based on the network pharmacology and molecular docking technology.Methods:The database of TCMSP and Swiss Target Prediction was searched to obtain the active ingredients and targets of kidney-protecting spirit pill,and the intersection with the disease targets was obtained.The protein-protein interaction(PPI)network of intersection targets was constructed,GO and KEGG enrichment were analyzed.The key targets and small molecules were obtained and their interactions were verified by molecular docking.Results:A total of 60 active ingredients and 112 therapeutic DN targets were predicted.The key components were Cerevisterol,3,9-di-O-methylnissolin,Jaranol,Palmidin A and 16α-Hydroxydehydrotrametenolic acid.The key targets were PIK3CA,MAPK1,AKT1,PIK3R1 and BCL2,which were closely related to cancer-related pathways,AGE-RAGE signaling pathway,endocrine resistance,lipids and atherosclerosis pathways in diabetic complications.Conclusion:The mechanism of kidney-protecting spirit pill in the treatment of DN is characterized by multi-components,multi-targets and multi-pathways,with synergistic effects between the herbs,which provides a basis for the study of the pharmacological effects of kidney-protecting spirit pill.

Objective:To analyze the anatomical morphological characteristics of the trabecular bone of human mandibular condyle by observing the distribution of volume of interests (VOI).Methods:The micro-CT images of a right condyle specimen of a 61-year-old adult male was analyzed in this study. The cylindrical VOI with both diameter and height of 2 mm were arranged, according to a certain pattern, as many as possible at various levels within the trabecular bone of the condyle. Each VOI had no intersection area. The selected VOI were divided into 5 parts: medial part, middle part, lateral part, anterior part and posterior part, with 6 layers from top to bottom. And the distribution of the overall anatomical morphological characteristics of three-dimensional (3D) images of the trabecular bone of the condyle was analyzed by using seven morphological parameters of each VOI, i.e. bone mineral density (BMD), bone volume/total volume (BV/TV), bone surface area/bone volume (BS/BV), trabecular thickness (Tb.Th), trabecular bone number (Tb.N), trabecular spacing (Tb.Sp) and trabecular bone pattern factor (Tb.Pf).Results:In the present study, totally 34 VOI were selected from the condyle specimen.The morphological distribution of the VOI was uneven in the 3D structure of the trabecular bone of the human condyle. BMD, BV/TV, Tb.N and Tb.Th were much higher at the middle part, while showed the smallest at the medial part. The anterior part demonstrated much higher parameters than the posterior part at the first, second, fifth and sixth layers, respectively, however, the posterior part showed much higher parameters than the anterior part at the third and fourth layers, respectively. The BMD was much higher at the first [(332.66±97.11) mg/cm 3] and sixth [(255.79±45.68) mg/cm 3] layers, while the lowest at the second layer [(255.79±41.06) mg/cm 3]. The BV/TV and Tb.N were much higher at the first layer, with the lowest at the fifth layer. The Tb.Th at the first layer [(0.11±0.03) mm] was much higher than the others, which were similarly lower. The BS/BV, Tb.Sp and Tb.Pf were lower at the first layer and much higher at the medial and lateral parts, while were lower at the middle and anterior parts. The posterior part demonstrated much higher BS/BV, Tb.Sp and Tb.Pf than the anterior part at the first, fifth and sixth layers, respectively. However, the anterior part showed much higher scores than the posterior part at the third and fourth layers, respectively. The ANOVA results showed that the 7 morphological parameters of VOI were not statistically significant amongst the 6 layers ( P>0.05). However, the 6 out of the 7 parameters, i.e. BV/TV, BS/BV, Tb.Th, Tb.N, Tb.Sp and Tb.Pf, were statistically significant amongst the five parts ( P<0.05), while the only parameter of BMD was not statistically significant ( P>0.05). Conclusions:The anatomical distribution characteristics of the trabecular bone of condyle were analyzed by using 3D imaging measurement based on the VOI. The results showed uneven distributions and indicated that the method of dividing the trabecular bone of mandibular condyle into VOI sets, which accorded with its specific anatomical characteristics, was feasible for further reference.

Objective To study the expression of collapsin response mediator protein 2 (CRMP-2) in the visual cortex of monocular form deprivation amblyopia rats.Methods Sixty-four 14-day-old rats were randomly divided into monocular deprivation amblyopia group and normal control group by random number table method.Right eyelid margin suture was performed at 14 days after birth in the monocular deprivation amblyopia group.Eight rats in the monocular deprivation amblyopia group and the normal control group were observed at 14,21,45 and 120 days after birth,respectively.Flash visual evoked potential (F-VEP) was used to dectect the latency and amplitude of P1 wave.The expression of CRMP-2 in visual cortex was observed by immunohistochemical method.The use and care of the animals complied with Regulations for the Administration of Affair Concerning Experimental Animals by State Science and Technology Commission.This study protocol was approved by Ethic Committee of the University of South China (No.20140228).Results F-VEP results showed that the amplitudes of P1 were decreased and latent periods of P1 were prolonged in the monocular deprivation amblyopia group compared with the normal control group (t=16.760,P =0.000;t =-22.919,P =0.000).CRMP-2 expression levels in the visual cortex of monocular deprivation amblyopia groups and normal control groups were compared at different time points after birth,and the differences were statistically significant (Fgroup =8.855,P =0.010;Ftime =63.091,P =0.000).Compared with normal control groups,the expressions of CRMP-2 at the postnatal 21,45 and 120 days were obviously decreased in the monocular deprivation amblyopia groups,the differences were statistically significant (all at P＜0.05).Conclusions CRMP-2 may be involved in the occurrence and development of amblyopia.

Objective: To evaluate adolescents’ self-esteem and explore its influencing factors in order to provide basic evidence for improving self-esteem level and mental health of adolescents. Methods: A total of 5 709 adolescents of different characteristics from both urban and rural areas in six provinces were investigated anonymously with the method of computer-assisted self-interview (CASI). Self-esteem was evaluated by Self-Esteem Scale (SES, scored 10-40 points). Results: The average score of self-esteem was 28.15,28.40, 28.97 and 27.45 point for junior high students, senior high students, college students and out-of-school adolescents, respectively. The difference of the scores among the four groups was statistically significant(F=27.64, 14.41, P<0.01). More than 80% adolescents felt they were people of worth, were able to do things as most other people, took a positive attitude toward themselves and were satisfied with themselves. About 50% of adolescents thought they were no good at all at times. Less than 20% adolescents thought they had enough respect for themselves. About 11.57% to 22.22% of adolescents felt sad about their own gender, about 37.56% to 61.49% of adolescents often or sometimes felt sad about their body image. The multiple linear regression analysis showed that those who had a good overall feeling of family, satisfied with their own gender, and less worried about their body image tended to have a higher self-esteem scores among 4 groups(P<0.01). Other related influencing factors included parental education level, family economic status, only-child or not, birth place and parental preference for gender of their child. Conclusion Adolescents’ self-esteem was fair, and many factors were associated with it. It is necessary to strengthen the education on gender equality among parents and adolescents and to pay more attention to mental health of the adolescents, who were in rural areas, with poor family atmosphere and economic status.
