Objective:
To understand the characteristics of KAP (knowledge, attitude and practice) related to the prevention of AIDS among young male MSM (man sex with man) in China, and to evaluate the comprehensive ability of AIDS prevention and associated factors to provide a scientific basis for the development of MSM AIDS prevention and control.
Methods:
From November to December 2019, sampling was recruited by using snowball sampling methods centered on Beijing and Tianjin. A cross-sectional survey of 222 young students MSM was conducted through an online questionnaire with information of general demographic characteristics, sexual behavior and HIV testing, psychological status and comprehensive ability to prevent AIDS.
Results:
Average score on comprehensive AIDS prevention knowledge was (87.64±6.41),with knowledge,attitude,and behavior score of (11.32±1.67)(54.87±3.36) and (52.18±4.30) respectively.The pass rate of knowledge, attitude, practice related to AIDS prevention were respectively 95.5%, 56.3%, and 27.0%. The separation rate of knowledge from belief was 42.8%, the separation rate of knowledge from behavior was 71.2%, and the separation rate of faith from information was 48.2%. Whether have received AIDS prevention education was related to knowledge qualification rate (P<0.01).
Conclusion
Current AIDS education is associated with the knowledge level of AIDS prevention among young MSM groups, but it is not enough to improve their attitudes and behaviors. The comprehensive ability of MSM in preventing AIDS among young students is still not optimistic. Intervention measures need to be further strengthened to improve the comprehensive ability of young students MSM group to prevent AIDS.

Objective:
To understand the characteristics of sexual partners and the influence of having multiple sexual partners on substance use among young male students man who have sex with men (MSM) in China, and to provide scientific basis for the prevention and control of HIV/AIDS among young MSM students.
Methods:
A mixed recruitment method of snowball sampling and respondent driven sampling was used to recruit young MSM students in Beijing and Tianjin, and a questionnaire survey was conducted among 220 participants from November to December 2019. Chi-square test and generalized linear model multi-factor Logistic regression were used to analyze the influencing factors of substance use before sexual behavior.
Results:
The average age of them was (22.39±2.57) years old, 84.5% of them were students, the average age of first sexual behavior was (18.83±2.45) years old, 44.1% of them had two or more sexual partners (including fixed sexual partners, temporary sexual partners and commercial sexual partners), 22.7% had more than one male fixed partner. After adjusting for age and education, having multiple sexual partners was risk factor for drinking alcohol before sex (aOR=2.97) or substance abuse (aOR=2.39). Having male temporary sexual partner was an risk factor in substance use before sexual behavior(OR=4.10).
Conclusion
The characteristics of sexual partners among young MSM students are complex, and the proportion of multiple sexual partners is high. Having fixed single sexual partner can reduce the risk of substance use before sexual behavior. AIDS prevention education for young MSM students should be further strengthened.

Chinese Journal of Practical Nursing 2023;39(11):806-814
Objective:To investigate phobia of acute myocardial infarction(AMI)patients after percutaneous coronary intervention(PCI), analyze its latent profile and explore the influencing factors in different categories.Methods:Three hundreds and thirty-five AMI patients who received PCI in Emergency Department ofthe First Affiliated Hospital of Naval Medical University from January 2021 to June 2022 were selected by convenient sampling method and prospective research as the survey objects. The basic situation questionnaire, cardiophobia scale (TSK-SV Heart), Hamilton Depression Scale (HAMD), Hamilton Anxiety Scale (HAMA), Connor Davidson Psychoelasticity Scale (CD-RISC) and Posttraumatic Stress Disorder Checklist (PCL) were selected to investigate them, and the linear growth model was selected to analyze the latent profile of postoperative phobia in AMI patients.Results:The score of post-operative phobia in AMI patients was (44.47 ± 7.25) points, and the latent profile analysis showed that AMI patients were classified into psychological type (156 cases, 46.57%), physiological type (164 cases, 48.96%) and severe type (15 cases, 4.47%). The severe phobia type was selected as the reference group, and multiple logistic regression analysis showed that compared with the severe phobia type, age, resilience, posttraumatic stress disorder (PTSD) and no or mild anxiety were significant influencing factors for phobia after PCI in patients with psychophobia type AMI ( P<0.05), while age and resilience were significant influencing factors for phobia after PCI in patients with physiological phobia type AMI ( P<0.05). Conclusions:Through latent profile analysis, there are three types of phobia in AMI patients after PCI: psychophobia, physiological phobia and severe phobia. Postoperative phobia is affected by psychological resilience, PTSD, age, chronic disease and depression. Therefore, targeted intervention should be carried out for AMI patients based on different characteristics of phobia after PCI to enhance their enthusiasm for rehabilitation.
