Objective To analyze the survival status and influencing factors among HIV/AIDS transmitted through homosexual contact from 2004 to 2022 in Nan'an District, Chongqing, China. Methods HIV infected/AIDS patients transmitted through homosexual contact in Nan'an District, Chongqing from 2004 to 2022 were selected for analysis. The survival rate was calculated using the life table method, the median survival time was calculated using the Kaplan-Meier method, and the survival curve was plotted. The Cox regression model was performed to identify factors influencing survival. Results A total of 3 110 subjects were included in the study, of which 1 199 individuals (38.55%) were transmitted through homosexual contact. The majority of patients were under 30 years old (694, 57.88%), unmarried (917, 76.48%), and had a higher education level of college or above (724, 60.38%), mainly belonging to the Han ethnicity (1 160, 96.75%). Students accounted for 10.43% of occupational status. The majority of patients were initially diagnosed with HIV (1 104, 92.08%), with 71.45% having a CD4+T lymphocyte count >350 cells/μL at the time of initial testing. The primary source of samples was from testing and consultation (52.88%), and the vast majority (93.16%) underwent antiviral treatment. The median survival time for patients transmitted through homosexual contact was 191.45 months, which was higher than 158.37 months of patients transmitted through other routes, demonstrating statistical significance (P<0.001). Multivariate analysis showed that among patients transmitted through homosexual contact, those with CD4+T lymphocyte count≤200 cells/μL had a higher risk of death compared to those with CD4+ T lymphocyte count>350 cells/μL. HIV infected/AIDS patients who did not receive antiviral treatment also had a higher risk of death. Conclusions From 2004 to 2022, the reported incidence level of HIV/AIDS in Nan'an District showed an overall upward trend, with a slight decrease influenced by respiratory infectious diseases.The risk of death for individuals infected through same-sex transmission routes had not yet been found to be significantly lower than that of other transmission routes, which may be influenced by the late diagnosis time and short follow-up time of individuals infected through same-sex transmission routes.

Objective To explore the most accurate T staging and optimal surgical method of lung adenocarcinoma of trans-lobe type, and to provide supportive diagnosis as well as therapeutic evidences for this disease. Methods A total of 192 postoperative patients, hospitalized in Tianjin Medical University General Hospital from January 2008 to June 2013, who were diagnosed with lung adenocarcinoma were recruited. Patients were divided into three groups according to the 7th edition of TNM staging criteria issued by the IASLC in 2009. A total of 163 patients with T2 stage were selected as Group T2, and 12 patients with T3 stage were selected as Group T3, both of which were considered as control groups. Other 17 pa?tients who were diagnosed as trans-lobe type of lung adenocarcinoma, were Group trans-lobe. The clinical data and progno?sis were compared between three groups. The trans-lobe type of lung adenocarcinoma was diagnosed based on imaging and pathological examination. Subtypes of trans-lobe lung adenocarcinoma were identified by referring to 2011 international mul?tidisciplinary classification standard of lung adenocarcinoma. Kaplan-Meier method was used to analyze the prognosis of dif?ferent subtypes and surgical modus in patients with lung adenocarcinoma of trans-lobe type. Results By comparison, the postoperative survival rate was significantly lower in patients diagnosed with trans-lobe type of lung adenocarcinoma than that of Group T2 (P<0.05), and no significant difference in survival rate compared with Group T3 (P>0.05). There were no significant differences in survival rates between different surgical modus (P<0.05). Seventeen patients with trans-lobe type of lung adenocarcinoma consisted of four subtypes, including 8 solid predominant, 5 acinar predominant, 3 papillary predomi?nant and 1 invasive mucinous adenocarcinoma. There were no statistical significances in postoperative survival time and sur?vival rates between four subtypes. Conclusion The clinical stage of trans-lobe type of lung adenocarcinoma should be clas?sified as stage T3. Both pulmonary bilobectomy and lobectomy combined with resection of proximal invaded lobe can be used as effective surgical therapies for trans-lobe type of lung adenocarcinoma.

Though parched Chinese herbal medicines contain less effective or index components, their pharmacological actions do not reduce or even become improved to some extent. However, the current studies related to material basis could not explain the changes in property, flavour and efficacy of parched Chinese herbal medicines. Meanwhile, due to the lack of objective and specific evaluation indexes, the quality evaluation could not reflect features of parched Chinese herbal pieces. Therefore, how to break the bottleneck for the studies on parched Chinese herbal pieces, make further innovation and conduct in-depth studies on the material basis of parched Chinese herbal medicines are common problems that medical scholars are facing. According to the findings in the previous studies, the author proposed to explain the material basis of parched Chinese herbal medicines by studying Maillard reaction and establish specific quality evaluation indexes according to the features of parched Chinese herbal pieces, and conducted relevant studies.
