目的探讨校园意外伤害发生的原因、特征和危险因素,为伤害预防与控制、残疾补偿、社会康复的有机结合提供参考依据。方法以1990—2002年因校园意外伤害造成脊髓损伤的 26例残疾学生作为个案调查研究对象。为了解校园意外伤害事故的致残原因及受伤后的处理情况,对仍在院接受治疗的残疾学生进行随访。结果伤害致残者中男生多于女生;初高中学生是伤害致残的高发人群(69%);校园意外伤害致残原因依次为:①体育训练;②跳水、潜水;③嬉闹摔伤;④高处坠落;⑤坠落物撞击;⑥钝器、刀砍击伤。医疗费用73%由校方支付。结论校园不安全隐患是危害学生生命安全的主要危险因素;提高青少年自我保护意识和自我防卫能力、加强安全教育、建立环境安全检查制度、定期对学校设施进行检查和维护是减少校园意外伤害事件的重要措施

10mg/L(n=22) group,and CRP10mg/L group with CRP10mg/L group and the concentration of CRP inverse correlation with serum ALB,Fe,Hb levels.Conclusions The elevated concentration of CRP is considered to be the most common cause of decreased EPO or hyporesponsiveness to EPO in CRF anemia patients. CRP level can predict whether CRF anemia,dificult or easily degree of the anemia correction for CRF patients,all that provide evidence for improving CRF anemia.

Objective: To understand the basic characteristics, sexual behavior and the use of recreational new drugs of young men who have sex with men (MSM) in Tianjin, and to explore the characteristics of young MSM who use recreational drugs, so as to provide reference for the policy making of HIV/AIDS prevention and control in universities. Methods: From January 1, 2018, solstice to December 31, 2018, participants were recruited in the bathrooms, bars and social network sites in Tianjin by snowball sampling. The basic demographic information, sexual behavior and recreational drug use of the participants were collected through face to face interviews and questionnaires. Logistic regression was used to analyzed the characteristic differences drug users and non users among young MSM. Results: A total of 826 young MSM were included in the study, 32 were infected with HIV, and the overall prevalence rate was 3.87 %. Totally 371 (44.92%) were drug users. Rush Poppers were the most common used drug ( 98.65 %). Of the young MSM using new drugs, 306 (82.48%) multiple drugs were used, 65 people ( 17.52 %) only one drug has been used. Among new drug users, multiple drug users had higher HIV prevalence rate (16.92%) than single drug users (4.57%). There were statistically significant differences between drug users and non users in age, age of first sexual behavior, household registration, sexual orientation, education level, sexual partners seeking routes, unprotected anal intercourse and HIV testing history( OR=3.70，5.51，0.51，0.60，4.64，0.40，0.52，1.98，2.29，P <0.05). Conclusion The utilization rate of recreational drugs among young MSM in Tianjin was high. Relevant departments should strengthen the propaganda of recreational drugs and HIV prevention among college students, improve the sexual health awareness of young MSM, and establish a long term HIV and recreational drug prevention system.

ObjectiveTo investigate the living condition of patients with spinal cord injury (SCI) after Tangshan earthquake.MethodsA questionnaire was designed for the investigation with 41 items including resident environment, income, mood, etc. The faculty of surveillance was composed of trained professionals. 1261 SCI patients living in Tangshan at present, 420 of which live in the sanatoriums and others live in the common families. The patients of four sanatoriums were chosen randomly from fourteen sanatoriums to be investigated in detail, and patients in the common families in two communities, one from city, another from countryside, were also chosen. This investigation was performed in 2003.The results are compared with that of 1988' survey.ResultsGreat improvements in the living condition of SCI patients in Tangshan were shown by the comparison of these two surveys, they were mainly in: the progress in the housing environments (100% SCI patients now live in the specially designed reconstructed houses); better medical services provided (the ratio of wheelchair available from 38.1% to 100%); the majority of the patients in acceptance stage of their disability; the increase of income (21.1% takes up various occupation) with a vigorous spare time; decrease in the common complications with SCI patients; although uremia was still the first death cause of the SCI patients, the percentage was decreased apparently; cardiovascular accident had a higher percentage in the death cause(the second leading cause), implies that the death cause of the SCI survivors had approached the normal person.ConclusionThe improvements reflect the social progress in China. However, still there are some problems to be remained for further solution: the ratio of employment is low; the insurance of living and medical rehabilitation needs further improvement.
