ABSTRACT
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.
ABSTRACT
BACKGROUND:There are many methods in the clinic to treat pelvic fractures, mainly conservative treatment, internal fixation and external fixation. Conservative treatment often causes complications due to poor reduction after fractures. Fixation has good effects on repair of unstable fractures, but fixation is seldom used for pelvic fractures. OBJECTIVE:To observe the effects of internal fixation on unstable pelvic fractures, and compare with conservative treatment and external fixation. METHODS:126 cases of unstable pelvic fractures from Longhua District People’s Hospital of Shenzhen City from January 2008 to June 2014 were divided into three groups:conservative treatment group, external fixation group and internal fixation group (n=42). After treatment, patients received X-ray examination. Lindahl imaging criteria were used as evidence. The quality of fracture reduction was evaluated. Patients were regularly fol owed up after treatment. The recovery of limb function was evaluated according to Majeed standard. Repair effects, the excel ent and good rates of fracture healing and cal us growth were evaluated in the last fol ow-up. RESULTS AND CONCLUSION:During the last fol ow-up, the total efficiency was 81%in the internal fixation group, 69%in the conservative treatment group, and 71%in the external fixation group, and results were significantly better in the internal fixation group than in the other two groups (P<0.05). The Lindahl and Majeed scores were significantly higher in the internal fixation group than in the other two groups (P<0.05). These results suggest that internal fixation for unstable pelvic fracture obtained better recovery effects and efficiency than conservative treatment and external fixation. Thus, the internal fixation is more suitable for patients with unstable pelvic fractures.
