Objective:To analyze the research hotspots and trends in the stigmatization of adolescents living with HIV/AIDS.Methods:Relevant literature was retrieved from the Web of Science Core Collection database, with the search covering from database inception to May 1, 2024. CiteSpace software was used to conduct bibliometric analysis, including the distribution of countries, institutions, authors, keywords, and cited references. Knowledge maps were generated to visualize the findings.Results:A total of 414 articles were included in the analysis. The number of publications has shown an overall upward trend. The United States had the highest number of publications (244 articles), the most productive institution was University of Cape Town (31 articles), and the most productive author was Linda-Gail Bekker (9 articles). Research hotspots mainly focused on stigmatization, behavioral patterns, mental health, treatment adherence, social support, and intervention models.Conclusions:Research on the stigmatization of adolescents living with HIV/AIDS is currently at a critical stage. Future studies should continue to explore the multidimensional impact of stigma and focus on the development of region-specific and individualized intervention models, while actively constructing a comprehensive support system within the field of public health.

Objective To investigate clinical characteristics and risk factors in early and advanced menopausal women with coronary heart disease (CHD).Methods A total of 259 menopausal women with CHD confirmed by coronary angiography in our hospital were selected as research objects,among whom 102 cases were in menopause≤ 10 years group,and 157 cases in menopause ＞ 10 years group.The clinical characteristics and risk factors of two groups were compared.Results The menopause ≤ 10 years group had higher incidence rate of hypertension and estrogen levels(P ＜ 0.05),but there was no significant difference in HLD-C,and TC levels,and carotid intima-media thickness (IMT) reached the degree of atherosclerosis.Menopause ＞ 10 years group showed a significantly higher incidence of diabetes,but LDL-C level and estrogen levels was significantly lower (P ＜ 0.05).The coronary artery disease in the menopause≤ 10 years group mainly occurred in single lesion,while the menopause ＞ 10 years group in double or multi-vessel lesion (P ＜0.05).Multivariate analysis showed that hypertension,diabetes,triglycerides,low-density lipoprotein cholesterol were risk factors for coronary heart disease,while estradiol was a protective factor.Conclusion Hypertension,diabetes,triglycerides,and low-density lipoprotein cholesterol and decreased estrogen are risk factors for women with coronary heart disease.Conditions of vascular endothelium and atherosclerosis of early postmenopausal women are better than the advanced postmenopausal women,and estrogen alternative is favorable for the patients.

OBJECTIVETo establish a HPLC method for the analysis of Danshensu (DSS), protocatechuic acid (PA) and protocatechuic aldehyde (PAL) of Xiangdan injection in rat's plasma, and to study pharmacokinetic characteristics of Xiangdan injection components in rats with m-hydroxybenzoic acid as internal standard.

METHODprotein was precipitated by 10% trichloroacetic acid and extracted by ethyl acetate. The plasma concentration was detected by HPLC, The pharmacokinetics parameters of DSS, PA and PAL were calculated by DAS2.0 software after iv injection.

RESULTDSS, PA and PAL have a good linear relationship in 0.68-44.0 mg x L(-1), 0.43-14.0 mg x L(-1) and 0.38-12.0 mg x L(-1), respectively. The average recoveries were more than 92% and the RSD of precision and stability of the test were between 0.4%-4.8%. DSS, PA and PAL showed a two-compartment open model, the half-life of absorption (t(1/2alpha)) were (6.26 +/- 4.6), (5.93 +/- 4.9), (18.44 +/- 2.4) min, the half-life of elimination (t(1/2beta)) were (64.11 +/- 8.8), (63.28 +/- 0.13), (69.315 +/- 0) min, the area under curve(AUC(0-infinity)) were (852.98 +/- 175.6), (83.84 +/- 58.8), (147.79 +/- 12.3) mg x min(-1) x L(-1).

CONCLUSIONA method with high recovery rate and good stability was established to determine the blood concentration of DSS, PA, PAL in Xiangdan injection and applied in its pharmacokinetics successfully.
