Objective To analyze the newly reported HIV-1 infection in several prefectures of Hubei Province，and analyze its influencing factors. Methods The limiting antigen avidity enzyme immunoassay(LAg-avidity EIA,LAg) was conducted on HIV-1 positive samples confirmed by Western blot of Hubei in 2017-2022. The demographic characteristics of the newly infected samples were analyzed by χ2 test.Logistic regression model was used to analyze influencing factors of new infection rate and predict the factors associated with the HIV-1 recent infection. Results There were 403 new cases of HIV-1 from 2017 to 2022 in several prefectures of Hubei Province, of which 77 were newly infected sorted by LAg,with a new infection rate of 19.11%. The newly confirmed HIV-1 persons of whom aged ≤24 years (40.00% new infection ratio), unmarried (29.41%), college or above (31.37%), and from Voluntary counseling and testing testing(VCT) clinics (40.00%) had a higher proportion of new infections, and the difference was statistically significant. Multivariate Logistic regression analysis showed that age ≤24 years old (aOR=4.346,95%CI: 1.342-14.075) and screening from the VCT clinic (aOR=6.761,95%CI: 1.460-31.319) were more likely to be newly infected. Conclusion The proportion of new HIV infection in several prefectures of Hubei province is relatively low in recent years.Further effective publicity and intervention measures for young students and the construction of VCT clinic should be continuously promoted to achieve early diagnosis and treatment.

Purpose Investigating the significance of ZO-1 different domains in the invasion and metastasis of gastric carcinoma (GC).Methods A tissue microarray that simulates the invasion and metastasis process of GC was created,and immunohistochemistry was performed to detect the expression of ZO-1 (α-pan),ZO-1 (α +) and ZO-1 (ZU5).Results The GC cell exhibited aberrant expression of ZO-1 (α-pan),ZO-1 (α +) and ZO-1 (ZU5) from membrane translocated to cytoplasm or no expression.The aberrant degree was increased with the invasion,however,was decreased in metastatic lymph node.The aberrant expression was associated with histological types.Conclusion The aberrant expression of ZO-1 (α-pan),ZO-1 (α +) and ZO-1 (ZU5),from membrane translocated to cytoplasm or no expression suggest that domains of PDZ3,GUK,SH3,ZU5 and alpha motif in ZO-1 might be involved in the invasion and metastasis of GC and maintaining of GC phenotype.The aberrant expression of these domains may be the one mechanism of ZO-1 involved in EMT or MET.

Objective A comparison of the quality of life and present status of happiness between AIDS patients in Provinces A and B helps to analyze the impact of the prevention and control mechanism on choice of the AIDS patient care mode.Methods The quality of the life questionnaire designed by WHO for AIDS patients and the Subjective Well-being questionnaire from the Memorial University of Newfoundland were called into play to describe the quality of life and present subjective wellbeing of 93 and 57 AIDS patients respectively from Province A and Province B;these patients were interviewed to understand the systematic arrangements of AIDS control in the two provinces and their AIDS patient care models.Results Differences found in the scores of the total quality of life and subjective wellbeing between the two provinces are significant statistically (P＜0.05);differences found in the scores of respective dimensions of quality of life,except for social relations,are significant statistically (P＜0.05).Results of interview found that the prevention and control mechanism of Province A feature a combination of medical administration and disease control departments,management by level of city,county,township and village.The care mode is characteristic of that centering on village doctors.The patient care mechanism in Province B features sectionalized management,and its model is characteristic of that centering on local CDC aided by infectious disease hospitals.Conclusion Establishment of the AIDS prevention and control mechanism should take into account features of local resources,and different regions should provide care models to fit the needs of local AIDS patients.
