Objective:
To analyze the infection characteristics of newly reported HIV/AIDS cases in Hangzhou City, so as to provide the reference for effective AIDS intervention.
Methods:
Newly reported HIV/AIDS cases in Hangzhou City in 2022 were recruited. Demographic information, HIV testing status, infection routes and sexual behaviors were collected using questionnaire surveys. Blood samples were collected before antiviral treatment, and HIV-1 pol gene sequences were detected to construct molecular transmission networks. The characteristics of HIV/AIDS cases, including infection routes, time, and location were analyzed. Factors affecting infection time and location among HIV/AIDS cases were analyzed using a multivariable logistic regression model.
Results:
A total of 1 007 HIV/AIDS cases were reported in Hangzhou City in 2022, with 907 cases (90.07%) completing questionnaire surveys. Among them, 833 were males (91.84%), and 532 had out-of-province household registrations (58.65%). Ninety-one molecular transmission networks were established, and 276 cases were involved, with homosexual contact as the main infection route (199 cases, 72.10%). There were 311 recently infected cases (35.34%) and 569 previously infected cases (64.66%) among 880 cases whose infection time could be determined. There were 531 locally infected. cases (70.24%) and 225 imported cases (29.76%) among 756 cases whose infection location could be determined. Multivariable logistic regression analysis showed that the HIV/AIDS cases who were identified through voluntary counseling and testing (OR=1.826, 95%CI: 1.055-3.175) and sought sexual partners through homosexual dating apps (OR=2.461, 95%CI: 1.193-5.234) were more likely to be recently infected; the cases who lived in Hangzhou City for more than one year (>1 to 5 years, OR=2.853, 95%CI: 1.552-5.358; >5 years, OR=3.534, 95%CI: 1.382-9.804), sought sexual partners through entertainment venues (OR=3.449, 95%CI: 1.390-8.935), online/social apps (OR=2.416, 95%CI: 1.084-5.488) and homosexual dating apps (OR=3.734, 95%CI: 1.677-8.493) were more likely to be locally infected; student cases were more likely to be infected outside Hangzhou City (OR=0.115, 95%CI: 0.019-0.525).
Conclusions
The newly reported HIV/AIDS cases in Hangzhou City in 2022 were primarily infected through homosexual contact, previously and locally. Seeking sexual partners through homosexual dating apps is an important influencing factor for recent and local infections, highlighting the need for strengthening traceback investigations of related cases.

Objective:To analyze the survival status and death factors of confirmed HIV-infected patients in Hangzhou to provide a basis for the formulation of AIDS prevention and treatment strategies.Methods:A retrospective cohort study was conducted. The data were from the HIV/AIDS Comprehensive Response Information Management System of the Chinese Disease Control and Prevention Information System.Epidemiological characteristics of HIV-infected patients were comparied in Hangzhou City from 2004 to 2023 by using chi-square Test. The survival rate of HIV-infected patients in Hangzhou was calculated by the life table method, the survival curves of different subgroups were described by the Kaplan-Meier method, and the Cox proportional hazard regression model was used to analyze the influencing factors of death risk. The SPSS 26.0 software was used for statistical analysis.Results:Among the 9 457 subjects, the total follow-up time was 58 004.18 person-years, 494 patients died, fatality rate of all-cause cases was 0.85 per 100 person-years.The average survival time was 18.59 (95% CI:18.40-18.78) years. Malignant neoplasms and pneumocystis pneumonia were the first (14.37%,71/494) and second (10.73%, 53/494) causes of death, respectively. Death within 6 months after diagnosis accounted for 42.51% (210/494), and suicide accounted for 4.25% (21/494). Multivariate Cox regression analysis showed that compared with those who received antiviral treatment (ART) within 3 months of diagnosis, those who received ART outside 3 months and those who did not receive ART had a 1.65 (95% CI:1.25-2.19) and 20.68 (95% CI:15.80-27.06) times risk of death, respectively. The HIV-infected patients with high CD4 +T lymphocytes (CD4) counts for the first time had a lower risk of death. The risk of death of patients with baseline CD4 counts of 200-349 cells/μl, 350-499 cells/μl, and ≥500 cells/μl was 0.38 (95% CI:0.29-0.49), 0.26 (95% CI:0.19-0.36), 0.21 (95% CI:0.14-0.31) times higher than that of baseline CD4 counts <200 cells/μl, respectively. Conclusions:The overall survival of the HIV-infected patients was good in Hangzhou from 2004 to 2023. Early detection of HIV infection and timely mobilization to participate in ART was the key to improving the survival rate of patients. At the same time, given the suicide problem of HIV-infected patients, suicide surveillance and depression and anxiety screening of HIV-infected patients should be further strengthened, and targeted psychological intervention policies should be implemented.

Objective :
To investigate the HIV-1 molecular transmission network among school students with newly confirmed HIV/AIDS in Hangzhou City from 2020 to 2021, so as to provide insights into AIDS control in school.
Methods :
School students with newly confirmed HIV/AIDS in Hangzhou City from 2020 to 2021 were sampled, and participants' demographics and epidemiological survey data were retrieved from the HIV/AIDS Control Information System of Chinese Disease Prevention and Control Information System. The HIV-1 pol gene was amplified in participants' blood samples using reverse transcription (RT) and nested PCR assays, and the HIV subtypes were characterized through multiple sequence alignments. The gene sequences were aligned among newly confirmed HIV/AIDS patients in Hangzhou City during the same study period. The genetic distance was estimated using the software MEGA 11, and the molecular transmission network was created using the software Cytoscape 3.9.1 to analyze the characteristics of clustered cases in the network.
Results:
A total of 99 school students were newly confirmed with HIV/AIDS in Hangzhou City from 2020 to 2021, including 98 men (98.98%), and 94 men who had sex with men (94.94%). The HIV-1 pol gene sequence was successfully amplified from 87 cases, and four HIV-1 subtypes were characterized, including CRF07_BC (49 cases, 56.32%), CRF01_AE (27 cases, 31.03%), CRF55_01B (6 cases, 6.90%) and CRF67_01B (5 cases, 5.75%). There were 30 molecular clusters in 50 MSM, with 2 to 16 cases in each cluster, and 27 molecular clusters associated with non-student cases, and clustered cases were all MSM. Infection route, location of schools and current address of non-student cases were identified as factors affecting case clustering, and the residence of schools was an important area of activity among clustered HIV/AIDS cases.
Conclusions
CRF07_BC and CRF01_AE were predominant HIV-1 subtypes among school students with newly confirmed HIV/AIDS in Hangzhou City from 2020 to 2021, and the transmission of HIV/AIDS strongly correlated with non-student cases, with men-men sexual behaviors as the predominant transmission route. The interventions for of MSM is recommended to be reinforced to block the transmission of HIV/AIDS from community to schools.

Nowadays hospitals have been at the forefront fighting against novel coronavirus pneumonia, with diagnosing and treating of patients as a top priority. In order to ensure the smooth progress of diagnosis and treatment, and prevent the occurrence of nosocomial infection, logistics support needs to make allowances for the isolation ward in time from the perspectives of logistics, facilities and equipment, and to transform the in-and-out double channels of ward access as required, thus setting up the partition of the three zones. Secondly, logistics support needs to optimize the logistics service workflow, including the medical waste management, the environmental disinfection isolation, and to optimize the catering service within hospitals to reduce the gathering and flow of personnel. Thirdly, logistics support needs to increase personnel training, and to eliminate psychological panic as well as to stabilize the logistics support team by putting logistics management cadres on the front line. Meanwhile, the logistics department needs to take over the hospital access screening work, strictly manage those who enter the hospital, maximize the safety and reliability of the logistics support within the hospital, and ensure the smooth progress of the epidemic prevention work.

Objective:To investigate the effect of Guilu Erxian Jiao (GEJ) on the negative feedback function of hypothalamic-pituitary-adrenal (HPA) axis and its possible mechanism in rats with post-traumatic stress disorder(PTSD).Methods:The PTSD rat model was established using single prolonged stress (SPS). Ninety six SD rats were randomly divided into control group (control), model group (SPS), GEJ group (GEJ) and paroxetine group (PRX) according to the random number table with 24 rats in each group. Except the control group, the rats in the other groups were constructed using the PTSD model. On the 8th day after the establishment of the model, the rats of the GEJ group (3.6 g/kg) and the PRX group (10 mg/kg) were respectively given the drug by gavage for 21 days. The rats in control group and SPS group were given the same amount of distilled water once a day for 21 days. After continuous administration for 21 days, 12 rats were randomly selected from each group for the dexamethasone suppression test (DST), then 6 rats were selected for the RT-PCR, and the remaining 6 rats were used for immunohistochemistry. The contents of plasma adrenocorticotrophic hormone (ACTH) were measured by Elisa. The expression levels of glucocorticoid receptor (GR), mineralocorticoid receptor (MR), adrenocorticotropic hormone releasing factor Ⅰ receptor (CRF1R) and adrenocorticotropic hormone releasing factor Ⅱ receptor (CRF2R) were detected by RT-PCR and immunohistochemistry.Results:(1) In DST, plasma ACTH level in SPS group was significantly lower than that in control group((145.89±19.41)μg/L, (203.59±35.78)μg/L, t=3.16, P<0.01), and that in the PRX group and GEJ group were significantly higher than that in SPS group((218.47±37.55)μg/L, t=3.98, P<0.01; (205.33±66.54)μg/L, t=3.26, P<0.01). (2) RT-PCR results showed that, in hippocampus, the GR mRNA and MR mRNA expressions in SPS group were significantly higher than those in control group((1.29±0.02), (1.00±0.06), t=6.88, P<0.01; (1.38±0.02), (1.00±0.05), t=7.97, P<0.01), and that in the GEJ group significantly decreased comparing to SPS group((0.96±0.07), t=7.87, P<0.01; (0.86±0.13), t=11.03, P<0.01). (3) Immunohistochemical results showed that, in hippocampus, the positive cell expressions of GR and MR in the SPS group were significantly higher than those in control group((84.33±12.82), (69.33±8.19), t=2.50, P<0.05; (77.33±6.65), (56.33±11.79), t=2.25, P<0.05), and that in the GEJ group significantly were lower than SPS group((68.33±4.55), t=2.67, P<0.05; (59.50±4.18), t=2.25, P<0.05). In amygdala, the positive cells expression of GR, MR and CRF1R in the SPS group significantly decreased compared with the control group((62.67±6.89), (77.17±10.70), t=3.10, P<0.05; (60.50±11.66), (91.83±15.63), t=3.43, P<0.05; (54.50±19.96), (88.17±22.43), t=2.31, P<0.05); and that in GEJ group significantly increased compared with the SPS group((74.33±5.85), t=2.11, P<0.05; (83.67±12.55), t=2.53, P<0.05; (88.67±16.28), t=2.35, P<0.05). Conclusion:GEJ can inhibit the enhanced HPA axis negative feedback function induced by SPS, which may be related to regulating expression of GR, MR and CRF1R in the hippocampus and amygdala.
