Objective:
To investigate the late identification of newly reported HIV/AIDS cases in Wuxing District of Huzhou City, Zhejiang Province from 2012 to 2021, and analyze the influencing factors, so as to provide the basis for improving AIDS prevention and control measures and promoting early identification of HIV/AIDS cases.
Methods:
Data pertaining to demographics, CD4+T lymphocyte counts, transmission routes and identification routes among newly reported HIV/AIDS cases in Wuxing District from 2012 to 2021 were collected through the HIV/AIDS Comprehensive Control System of Chinese Disease Prevention and Control Information System. The proportions of late identification of cases with different characteristics were descriptively analyzed, and factors affecting late identification were identified using a multivariable logistic regression model.
Results:
Totally 627 HIV/AIDS cases were reported in Wuxing District from 2012 to 2021, including 555 males (88.52%), and had a mean age of (40.30±15.98) years. There were a total of 212 cases with late identification, and the annual average proportion was 33.81%. The proportions of late identification ranged from 51.85% in 2012 to 28.00% in 2021, with no significant changing trend (χ2trend=1.152, P=0.283). Multivariable logistic regression analysis showed that higher proportion of late identification was more likely seen in the registered cases in Wuxing District (OR=1.651, 95%CI: 1.140-2.393), cases at ages of 40 years and older at diagnosis (OR=1.719, 95%CI: 1.068-2.766), and cases identified by medical institutions (OR=1.809, 95%CI: 1.136-2.881).
Conclusion
HIV/AIDS cases registered in Wuxing District, aged 40 years and older, and identified by medical institutions have higher proportions of late identification in Wuxing District from 2012 to 2021.

Objective:To evaluate the efficacy of chemotherapy for advanced biliary tract carcinoma and the factors that influence sur-vival. Methods:A total of 91 cases of advanced biliary tract carcinoma from January 2010 to April 2015 were enrolled in our study. The patients' characteristics, chemotherapy regimens, and effects were analyzed. Results:We enrolled 56 males and 35 females with a me-dian age of 57 years. A total of 90 patients were assessable for their responses to first-line chemotherapy. A total of 69 patients re-ceived the GP regimen, whereas 21 patients received some other regimens. The disease control rate (DCR), median progression free survival (mPFS), and median overall survival (mOS) were 68.1%versus 52.4%, 5.10 months versus 2.50 months (P=0.025), and 13.00 months versus 7.20 months, respectively. Only 31 patients received S-1 based regimens, and 12 patients received some other regi-mens as second-line chemotherapy. The DCR, median PFS, and median OS showed no statistical differences. Only four patients re-ceived S-1 based regimen plus bevacizumab as second-line chemotherapy (median PFS 5.3 months;median OS 7 months). Hematologi-call toxicity was the most common side effect in the first-line GP regimen. The side effects of the S-1 based chemotherapy regimen was relatively less. Conclusion:The GP regimen is an effective first-line chemotherapy for advanced biliary tract carcinoma, whereas S-1 ap-pears as an effective second-line chemotherapy drug. Bevacizumab-based regimens may be effective and require further validation.

Background Radiation-induced liver damage is a major complication for primary liver cancer and other upper abdominal tumors during radiation therapy. The early biological effects of radiation-induced liver damage at different doses of radiation and its mechanisms of action have not yet been elucidated. Objective To establish X-ray-induced radioactive mouse liver damage model and explore the level of oxidative stress and its correlation with nuclear factor-κB (NF-κB) and transforming growth factor-β1 (TGF-β1). Methods A total of 24 male C57BL/6J mice aged 6 weeks were randomly divided into 4 groups (control, 0.8 Gy, 1.6 Gy, and 4 Gy), with 6 mice in each group. X-rays irradiated the whole body of mice singly in each dose group. At 24 h after radiation, histopathological changes in mouse liver were evaluated; peripheral blood cell count, serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels, as well as liver tissue superoxide dismutase (SOD) activity, malondialdehyde (MDA) level, reduced glutathione (GSH) level, and 8-hydroxy-2′-deoxyguanosine (8-OHdG) level were measured; real-time fluorescence quantitative PCR was used to detect liver tissue NF-κB p65 and TGF-β1 mRNA expression levels; the correlations of oxidative stress indicators with NF-κB p65 and TGF-β1 mRNA expression levels were analyzed by Pearson correlation. Results Compared with the control group, at 24 h after different doses of X-ray radiation, early injury-related histopathological changes were observed in liver, and the serum levels of AST and ALT were significantly increased in the 4 Gy group (P<0.05); the numbers of peripheral blood leukocytes and lymphocytes were decreased in the radiation exposure groups (P<0.05), showing a decreasing trend with increasing radiation doses; the levels of liver oxidative stress indicators (MDA, SOD, and GSH) in exposed mice were significantly increased (P<0.05), showing an increasing trend with increasing radiation doses. The liver 8-OHdG were significantly increased in the 1.6 Gy and 4 Gy groups compared with the control and the 0.8 Gy groups, respectively (P<0.05). The NF-κB p65 and TGF-β1 mRNA expression levels in the liver of mice were significantly increased in the 1.6 Gy and 4 Gy groups compared with the control group (P<0.05). The TGF-β1 mRNA expression level also exhibited an increasing trend with increasing radiation doses. The results of correlation analysis showed that the levels of MDA, SOD, GSH, and 8-OHdG in liver tissues were significantly and positively correlated with the expression levels of NF-κB p65 and TGF-β1 mRNA (P<0.05). Conclusion X-rays of various doses can affect the degree of liver injury, peripheral blood cell count, serum levels of AST and ALT, and liver oxidative stress levels in mice. The level of oxidative stress induced by X-ray is positively correlated with NF-κB and TGF-β1 in liver tissues, and it may participate in the process of radiation-induced liver injury.
