Objective: To investigate the immune reconstitution of HIV/AIDS patients and its influencing factors after receiving antiviral therapy (ART) in Hangzhou City, so as to provide insights into improving the treatment effects and quality of life in HIV/AIDS patients. Methods: A retrospective cohort of HIV/AIDS patients who began antiviral treatment between January 1, 2016 and August 31, 2021 and had a baseline CD4+T lymphocyte (CD4) counts of less than 500 cells/μL or a baseline CD4/CD8+T lymphocyte (CD8) ratio of less than 0.8 in Hangzhou City was followed up until August 31, 2023. Demographic information, antiviral therapy in formation, CD4 counts, and CD4/CD8 were collected from the Chinese Disease Prevention and Control Information System. A good immune reconstitution was defined as having CD4≥500 cells/μL and CD4/CD8≥0.8. The immune reconstitution status of HIV/AIDS patients were analyzed, and factors affecting immune reconstitution were identified using a multivariable Cox proportional risk regression model. Results: A total of 3 349 HIV/AIDS patients were enrolled, with a median age at ART of 31 (interquartile range, 20) years. There were 3 075 males (91.82%), 1 600 cases with college education and above (47.78%) and 2 455 cases at WHO clinical stage Ⅰ-Ⅱ(73.31%). There were 1 368 cases with good immune reconstitution, accounting for 40.85%, and the proportion of HIV/AIDS patients with good immune reconstitution that began ART in 2016 was the highest, reaching 51.90%. Multivariable Cox proportional risk regression model identified WHO clinical stage (Ⅰ-Ⅱ, HR=2.529, 95%CI: 2.023-3.162), timely ART (HR=1.196, 95%CI: 1.027-1.394), initial treatment regimen (TDF+3TC+NVP/EFV, HR=2.185, 95%CI: 1.891-2.524; integrase inhibitors, HR=8.509, 95%CI: 6.706-10.795), baseline CD4/CD8 (≥0.1, HR: 1.600-4.515, 95%CI: 1.061-6.661), baseline hemoglobin (<90 mg/dL, HR=0.327, 95%CI: 0.121-0.880), hepatitis B infection (HR=0.619, 95%CI: 0.457-0.840) and hepatitis C infection (HR=0.308, 95%CI: 0.099-0.956) as factors affecting immune reconstitution in HIV/AIDS patients. Conclusion The immune reconstitution in HIV/AIDS patients after ART is associated with WHO clinical stage, timely ART, initial treatment regimen, baseline CD4/CD8, baseline hemoglobin and hepatitis B or C infection.

Objective To observe the cough-preventing and asthma-relieving effect of Shaonianhong Fanxing Anti-asthmatic Syrup(SFAS).Methods The cough-preventing effect was observed in the experiment of cough induced by ammonia in mice;the phlegm-removing effect was observed in the experiment of eliminating phlegm with phenol red in mice;and the and-asthmatic effect was observed in the experiments of histamine inducing asthma and isolated tracheal smooth muscles of cavies.Results SFAS Can prolong the coughing time induced by ammomia,enhance the excretion of sputum,extend the delitescence period of ohosphoric acid hismmine induced asthma and restrain the contraction of isolated tracheal smooth muscles.Conclusion SFAS has phlegm-removing,cough-preventing and anti-asthmatic effects.

In this paper, the adsorbent properties of Polymyxin B immobilized polystyrene microbeads to remove endotoxin from plasma were studied and the factors that affected the absorption of endotoxin were discussed. The rat models of endotoxemia were established, which were used in hemoperfusion. The experiment results indicated that the novel affinity adsorbent could remove endotoxin from plasma effectively. Moreover, the results also showed that Polymyxin B immobilized polystyrene microbeads was a fine biomaterial of hemoperfusion as well as exhibited a satisfactory blood compatibility.

Objective: To explore the cognitive functions of the elderly aged 60 years and above in Xiamen, and whether TV watching time would affect those functions. Methods: We conducted a cross-sectional study on 3 230 registered individuals aged 60 years and above in Xiamen from July to October in 2016 with a multi-stage random sampling method. Montreal Cognitive Assessment (MoCA) was used to measure cognitive functions and ordinal logistic regression was used to quantify their associations with TV watching time. Results: A total of 2 944 respondents were included in this study. The overall age of them was (70.14±7.81) years. 51.49% (n=1 516) of all participants were men. Overall, the mean scores of MoCA in general and each subdomain cognitive function were 18.65±6.43 (general), 5.43±1.17 (orientation), 2.33±1.95 (memory), 1.80±1.52 (visuospatial), 1.66±1.20 (executive), 4.54±1.71 (attention), and 4.09±1.64 (language). Compared to those who watched TV no more than 2 hours per day, the elderly who did not watch TV had a worse performance in general, orientation, memory, visuospatial, executive, attention, language function, with OR (95%CI) values about 0.50 (0.35-0.71), 0.52 (0.37-0.73), 0.68 (0.48-0.96), 0.67 (0.47-0.96), 0.48 (0.34-0.67), 0.56 (0.41-0.77) and 0.45 (0.33-0.62), respectively. As to respondents who watched TV more than 2 hours but no more than 4 hours per day, they had a better performance in general, executive, attention, language, and orientation function with respective OR (95%CI) values about 1.24 (1.05-1.47), 1.20 (1.02-1.41), 1.41 (1.19-1.67), 1.51 (1.28-1.77) and 1.33 (1.08-1.64). Conclusion The elderly aged 60 years and above in Xiamen City with TV watching time between 2 and 4 hours per day had a good performance in cognitive functions compared to those with more or less TV watching time.

A 3-week practice-oriented training course on chronic obstructive pulmonary disease (COPD) management was conducted in December 2020, 34 primary care physicians from township or community health service centers attended the course. The impact of the training course on the knowledge levels of COPD management was evaluated with a questionnaire survey, the questionnaire contained the knowledge of COPD and its management. The survey showed that before the training, the participants had low knowledge levels on the definition of COPD and its risk factors; 67.6% (23/34) were not aware of COPD-related guidelines and new developments, and 17.6%(6/34) had conducted COPD follow-up assessments, pulmonary rehabilitation, and health education; only 8.8% (3/34) had used the improved British Medical Research Council Dyspnea Index (mMRC) and the chronic obstructive pulmonary disease assessment test (CAT) for patient self-assessment; there was no pulmonary function instrument in their units, and only 3 doctors (8.8%) had previously participated in pulmonary function training and knew indications and contraindications of the pulmonary function test, and complete report interpretation; all participants were unable to use common inhalation devices and master inhalation techniques completely and correctly; 11.8% (4/34) had assessed patients′ handling inhalation devices and performing inhalation. After the training, the knowledge levels of COPD clinical features, lung function and inhalation technique were significantly improved, and the scores were significantly increased compared with those before the training ( P<0.001). The study shows that primary care physicians have insufficient knowledge and management skill of COPD. The practice-oriented training can significantly improve the knowledge and skills of primary care physician for COPD management in the community.
