Objective:To understand the prevalence and related factors of three common chronic diseases, hyperlipidemia, hypertension and diabetes in HIV-infected persons.Methods:As of December 2023, HIV-infected persons >15 years old who are receiving antiviral therapy (ART) and follow-up in Henan Province were selected as the study objects. Questionnaires, physical examinations, and blood samples were collected to collect demographic information, ART, body weight, blood lipids, blood pressure, and blood sugar of HIV-infected persons. The logistic regression model was used to analyze the related factors of hyperlipidemia, hypertension and diabetes.Results:Among 4 023 HIV-infected patients, the prevalence rates of hyperlipidemia, hypertension, and diabetes were 64.47% (2 594/4 023), 16.80% (676/4 023), and 10.54% (424/4 023), respectively. Multivariate analysis showed that hyperlipidemia was positively associated with ≥40 years of age, overweight and obesity, two nucleoside reverse transcriptase inhibitors (NRTIs) + proteasome inhibitors (PIs) regimen and two NRTIs+ integrase inhibitor regimen, and negatively associated with low body weight. Hypertension was positively correlated with the age group ≥40 years old, family history of cardiovascular and cerebrovascular diseases, overweight and obesity, ART time ≥0.5 years, and negatively correlated with low body weight. Diabetes was positively associated with age group ≥40 years, family history of cardiovascular and cerebrovascular disease, overweight and obesity, and negatively associated with the use of two NRTIs+PIs treatment regimens.Conclusions:In 2023, the prevalence of hyperlipidemia, hypertension, and diabetes among HIV-infected people in Henan Province was relatively high, and the risk of common chronic diseases among those ≥40 years old, overweight and obese, and those with a family history of cardiovascular and cerebrovascular diseases was also relatively high. It is recommended to strengthen the prevention and management of common chronic diseases among HIV-infected people.

Objective:To investigate the clinical phenotype and genetic characteristics of a family with Dentinogenesis imperfecta type Ⅰ(DGI-Ⅰ).Methods:Clinical data were collected from a patient with DGI-Ⅰ admitted to the Reproductive Medicine Department of the Affiliated Hospital of Jining Medical University in March 2024. Clinical and familial data were retrospectively collected. Peripheral blood samples (5 mL each) were obtained from the proband and her family members for genomic DNA extraction, followed by whole-exome sequencing (WES) and Sanger sequencing validation. The pathogenicity of the detected variants was assessed according to the Classification Standards and Guidelines for Genetic Variants formulated by the American Society of Medical Genetics and Genomics (ACMG) (hereinafter referred to as the " ACMG Guidelines" ). The study was approved by the Ethics Committee of the Affiliated Hospital of Jining Medical University (Ethics No. 2024-08-C012), and written informed consent for clinical research were obtained from all participants.Results:The proband, a 35-year-old female, presented with translucent yellow primary teeth and progressive browning, darkening, and loss of permanent teeth, without skeletal abnormalities. Affected family members exhibited similar phenotypes. Genetic testing revealed a heterozygous COL1A2 variant (c.1503+ 1G>A) in the patient and other members, while unaffected family all members lacked this variant. Based on the ACMG Guidelines, this variant was classified as likely pathogenic(PM4 + PP1_Strong + PM2_Supporting). Conclusion:The COL1A2 c. 1503+ 1G>A heterozygous variant is the disease-causing mutation in this family. Above finding has expanded the mutational spectrum of the COL1A2 gene and provided a basis for genetic counseling and diagnosis in similar cases.

Under the background of breaking the " five only" evaluation criteria, continuously optimizing the scientific research performance evaluation system of hospitals to mobilize the enthusiasm and creativity of scientific researchers and guide the direction of scientific research development plays an important role in enhancing the overall scientific research capability of hospitals. Through literature analysis and expert consultation, a certain hospital has constructed a personal scientific research performance evaluation index system for medical staff in tertiary public hospitals, oriented towards innovation quality and member contributions, and began to implement it throughout the hospital in 2021. This index system included four categories of scientific research performance: vertical scientific research projects, academic influence, science and technology awards, and transformation of achievements, with a total of 20 indicators. The annual scientific research performance score of an individual would serve as the basis for the distribution of year-end scientific research performance and an important reference for applying for key and major projects within the hospital. After the application of this evaluation index system, the enthusiasm of medical staff for scientific research has been effectively stimulated. The average individual scientific research performance score increased from 0.974 in 2020 to 1.220 in 2023. All scientific research indicators involved in the evaluation system have shown growth, with a significant increase in high-quality results. This evaluation system can provide a reference for the scientific research performance evaluation of public hospitals under the background of breaking the " five only" evaluation criteria.

Objective To systematically evaluate the influencing factors for antiretroviral therapy(ART)discontinuation in Chinese human immunodeficiency virus(HIV)/acquired immuno deficiency syn-drome(AIDS)patients.Methods A computer-based search was conducted in PubMed,Web of Science,Em-base,The Cochrane Library,CNKI,Wanfang,VIP,and China Biology Medicine(CBM)databases for studies on influencing factors of ART discontinuation in Chinese HIV/AIDS patients from the establishment of the databases to August 2024.Meta-analysis was performed on the included studies by using Stata16.0.Results A total of 17 studies were included.Meta-analysis showed that the following factors were associated with ART discontinuation:male gender(OR=1.301,95%CI:1.099-1.540),age≥50 years(OR=1.212,95%CI:1.109-1.324),unmarried/divorced/widowed marital status(OR=1.198,95%CI:1.060-1.354),education level was or below senior high school(OR=1.778,95%CI:1.508-2.096),infection route was in-travenous drug use(OR=2.420,95%CI:1.989-2.945),baseline CD4 cell count>500 cells/μL(OR=1.157,95%CI:1.020-1.313),tuberculosis co-infection before ART(OR=1.559,95%CI:1.398-1.739),hepatitis B co-infection before ART(OR=1.554,95%CI:1.305-1.851),AIDS-related symptoms occur be-fore ART(OR=1.245,95%CI:1.148-1.351),time from diagnosis to treatment initiation≥365 days(OR=1.449,95%CI:1.301-1.615),initial treatment regimen containing zidovudine(OR=1.573,95%CI:1.206-2.052),treatment at county-level or lower institutions(OR=1.204,95%CI:1.153-1.257),exist drug adverse reactions(OR=7.043,95%CI:3.142-15.786),and compliance education(OR=0.182,95%CI:0.094-0.352).Conclusion There are multiple factors influencing ART discontinuation in Chinese HIV/AIDS patients.Early identification of individuals at risk of discontinuation and targeted interventions are nec-essary to promote their maintenance of ART.

Objective To explore the effect of ionizing radiation on the fertility of male mice and its offspring and the intergenerational and transgenerational genetic effect mechanism of ionizing radiation through sperm DNA methylation sequencing.Methods Eight-week-old(8 w)C57BL/6 male mice were irradiated with 60Co radiation source at a dose of 3 Gy(3 Gy-F0 group,n=60)and non-irradiated mice of the same age were used as controls(0 Gy-F0 group,n=60).Afetr 5-,6-,7-,8-,9-,10-,11-,and 12-week radiation,the mice began to breed with healthy females,and the first generation(F1 generation)male mice then breed with healthy female mice to obtain the offspring(F2 generation)male mice.The structure of testis was detected by hematoxylin-eosin staining;serum follicle-stimulating hormone(FSH),testosterone(T)and luteinizing hormone(LH)levels were determined by enzyme-linked immunosorbent assay.Automatic sperm analysis system was used to detect sperm concentration and activity.The DNA of F0 generation sperm was extracted and analyzed by genome-wide DNA methylation sequencing.MassARRAY methylation sites were detected in sperm DNA of F1 generation mice and verified by quantitative polymerase chain reaction(qPCR).Results Compared with the 0 Gy-F0 group,male mice in the 3 Gy-F0 group gradually regained their reproductive ability 7 weeks after ionizing radiation.There was no significant difference in the number of surviving offspring between the 3 Gy-F0 group and 0 Gy-F0 group 10-11 weeks after radiation(P＞0.05).There were no significant differences in body weight,testicular morphology,or sperm concentration of F1 generation mice between the 3 Gy-F1 group and the 0 Gy-F1 group(all P＞0.05).However,compared with the 0 Gy-F1 group,the contents of LH,FSH and T in the 3 Gy-F1 group were all decreased(all P＜0.05),the testicle volume,total sperm motility rate,forward motility rate and the fertility were considerably decreased(all P＜0.05).DNA methylation sequencing showed that more differentially methylated genes were enriched in the pathway regulating microtubule formation.MassARRAY methylation sites analysis showed that the methylation level of Mid1 was significantly increased(P＜0.05 or P＜0.01).Mid1 was verified down-regulated in Fl and F0 sperm by qPCR(P＜0.05 or P＜0.01).However,there were no significant differences in volume of testes,testicular index,sperm concentration,sperm motility,hormone levels or Mid1 expression level between 0 Gy-F2 and 3 Gy-F2 mice in F2 generation male mice(all P＞0.05).Conclusion Sperm damage in mice caused by ionizing radiation at a dose of 3 Gy can recover by itself.However,it may decrease sperm activity by regulating Mid1 methylation level of sperm in F1 mice,thus affect the fertility of F1 mice,but has no effect on the fertility of male F2 mice.

Objective To explore the effect of enhancer of Zeste homolog 2(EZH2)on hepatocellular car-cinoma HepG2 cell proliferation by inhibiting Wnt/β-catenin signaling pathway.Methods The expression lev-els of mRNA and protein of EZH2 in hepatocellular carcinoma HepG2,SMMC-7721,BEL-7402 cells and nor-mal hepatocytes were detected by real time fluorescence quantitative reverse transcription polymerase chain reaction and Western blot.Transfected siRNA EZH2 and siRNA control in hepatocellular carcinoma HepG2 cells.siRNA EZH2 in HepG2 cells and siRNA control were transfected,MTT was used to measure the HepG2 cells' ability to proliferate.Western blot technique was used to identify the expression levels of proteins.By transfecting siRNA EZH2 in HepG2 cells and administering an activator of the Wnt/β-catenin signaling path-way,MTT assay was used to determine the proliferation ability of cells.Results The EZH2 mRNA and EZH2 protein levels in hepatocellular carcinoma HepG2,SMMC-7721 and BEL-7402 cells were higher than those in normal hepatocytes(P＜0.05),and the mRNA and protein levels of EZH2 in HepG2 cells were high-er than those in SMMC-7721 and BEL-7402 cells(P＜0.05).siRNA EZH2 could significantly inhibit the mR-NA and protein levels of EZH2 in hepatocellular carcinoma HepG2 cells.After EZH2 expression inhibition,the cell viability of HepG2 cells was lower at 24,48,72 h(P＜0.05),Wnt 1 and β-catenin protein levels were lower(P＜0.05).Conclusion EZH2 is overexpressed in hepatocellular carcinoma HepG2 cells,and knock-down of EZH2 significantly inhibits the proliferative ability of HepG2 cells and decreases the levels of proteins related to the Wnt/β-catenin signaling pathway.
