Many scholars has been engaged in studying the methods prevent tendon adhesion following basketball sports injury. The article reviews the preventive effects of several biomaterials, such as chitosan, absorbable anti-adhesive film, sodium hyaluronate, polylactic acid, on tendon adhesion following basketball sports injury.

Sports biomechanics is a strong experimental frontier branches of science and aims to study human body motion,to explore human motion rule by human anatomy,human physiology,mechanics theories and methods. Studies on muscle mechanics are basis of studying sports biomechanics and movement training. Muscular mechanical property is very complex,and related to composition of muscle. Under different sports conditions,biomechanics characteristics of skeletal muscle are different,so the sports injuries are varied.

Sports biomechanics, as a branch of biomechanics, studies mechanics characteristics and mechanics relationship of human internal locomotor system and human external bodily movement to fundamentally understand the rule of biomechanics characteristics under the sports condition. Muscular function and mechanics characteristics are a basis of human motion, and muscle mechanics is a basis of sports biomechanics research and sports training.

Objective: To investigate the socio-demographic and cultural factors of spousal violence(SV) in order to provide systematic basis of SV prevention.Methods: By using multistage stratified sampling methods,3087 households were selected from Chenzhou city in Hunan Province.After screening,384 households had SV.Among them 80 households were randomly selected for study,in which 80 perpetrators were not in the domestic violence(DV) group.For the non-DV group,after matching of family’s structure,96 households without violence behavior were selected,in which after matching of gender and age with perpetrators,96 normal controls were enrolled.Results: The ratio of male perpetrators(81.3%) was more than female(18.7%),but female(81.3%) was more than male(19%) victims(P

BACKGROUND: Neurasthenia is commonly believed attributing to the complex influence of psychological, social and biological factors.OBJECTIVE: To probe the correlation of neurasthenia with personality,life events and the positive rate of serum Epstein-Barr (EB) virus.DESIGN: Case-controlled observation and prospective paired analysis.SETTING: Mental Health Institute of Second Xiangya Hospital Affiliated to Central South University.PARTICIPANTS: From May to October 2000, patients with neurasthenia,selected from the Clinical Ward of Mental Health Institute of Second Xiangya Hospital Affiliated to Central South University for medical treatment,19 males and 11 females, with mean age of (27±8), the course of disease ranged from 0.5 to 20 years with the average of 4.0 years, enrolled in this study. According to 1:1 paired principle, 30 matched volenteers, their relatives, or students of Xiangya Hospital were randomly selected as controls.Two groups were matched in age, sex and education, patients with psychological and physical disease were excluded. All participants were given written informed consent.METHODS: The level of serum EB virus IgG and IgM of two groups were determined by using ELISA methods. Blood samples were colleted before and after treatment in experimental group, while blood samples were only collected once in control group. Patients in experimental group were given routine medication and integrative psychotherapy according to their state of illness, and Eysenck personality questionnaire (EPQ) were filled in before and after treatment (including four dimensionalities: neuroticism, psychoticism, extroversion/introvision and lie, amongst which higher scores for extroversion/introvision dimensionality represented extroversion and lower dimensionality represented introvision; higher scores of neuroticism dimensionality suggested anxiety and worry. Higher scores for psychoticism suggested solitude and inadaptability to the outer environment), life events scale (including the total score for life events, positive events value and negative events value), and symptom checklist 90 (SCL-90) (consists of 10 factors scored of 0-4, representing non-symptom to severer symptom) were used to assess the clinical symptom. EPQ and SCL-90 were adopted on patients at four months after treatment for self-comparison. EPQ and life events scale were taken on healthy controls, the scores compared with that of experimental group before treatment.for EPQ, the total scores for SCL-90 and positive rate of EB virus in patients with neurasthenia before and after treatment.RESULTS: Totally 27 patients were followed up at 4 months after treatment, and 3 cases lost due to long distance from hospital, thereby 27 cases in experimental group and 30 cases in control group were remained in the roticism in neurasthenia group was significantly higher than that of control group (57.59±10.79, 40.58±8.68, t=6.536, P ＜ 0.01), scores of extroversion/introvision were obviously lower than that of control group (46.31 ±10.79, 53.50±11.28, t=3.203, P ＜ 0.01). In neurasthenic group, scores for neuroticism was obviously decreased after treatment in contrast to before events scale: The total scores and negative scores in neurasthenia group was significantly higher than that of control group (19.73±17.25, 18.93 tal scores for SCL-90: The total scores for SCL-90 was obviously declined after treatment comparing to that of before treatment in neurasthenia of EB virus IgG and IgM: The positive rate in neurasthenia group was significantly higher than that of control group (76.67% vs 26.67% );and positive rate of serum EB virus were proved to be two important pathogenic factors for neurasthenic patients.CONCLUSION: Patients with neurasthenia possess susceptible personality, such as neuroticism and introvision, and commonly experienced negative life events before illness. Moreover the positive rate of EB virus in neurasthenic patients is higher, which might be associated with the higher glucocorticoidinduced EB virus activation under stress state.

Objective: To study the group consultation in preventing psychological disorders causing by retirement. Methods: Implement group consultation to 23 elderly staff members from a government organization. Both the self-designed health knowledge and SCL-90 questionnaires were used before and after he/she participated the group consultation. Comparisons were conducted of the results getting from 18 old people who had never had the consultation. Results: There was significant difference in two groups. Experiments show that group consultation can impressively held to improve the psychological and behavior disroders. Conclusion: Group consultation is an effective way to prevent psychological problems causing by retirement.

Objective:To study the effect of a three-in-one counseling model on mental health of medical students Method: A three-in-one counseling model composed of mental health education, group counseling and individual counseling was applied to 150 freshmen of a medical school (study group) Other 150 freshmen were collected as control The intervention lasted for 1 year The effect was assessed with EPQ, SCL-90, GWB (gross well being), SCCS (self-consistency and congruence scale), SAD (social avoidance and distress scale) and LESU (life events scale of undergraduates) at the baseline, in the middle and at the end of the study Result: After intervention, the study group had lower score in psychoticism of EPQ (46 3?7 5) than control group (50 7?11 9), and higher score in flexibility (48 9?5 6) than control (46 8?5 9) The total score and many subscores of SCL-90 decreased in study group While the scores of social avoidance and distress increased in control group Conclusion: The three-in-one counseling model has effect on balancing personality, reducing psychosomatic symptoms, facilitating self consistency and improving social interaction of medical students

Objective:To develop the Chinese version of the 22-item Impact of Event Scale-Revised (IES-R-C) and examine its reliability and validity. Methods:A sample of 439 female offenders experiencing at least one traumatic life event was tested. The authors examined the IES-R-C's retest reliability, internal consistency, discriminative validity and predictive value of the cut-off. Results:The test-retest reliability coefficient was 0.86;The Cronbach's coefficient of the IES-R-C was 0.96;The mean inter-item correlation coefficients ranged from0.42 to 0.60;The correlation coefficient of the three factors with the total scale scores ranged from0.84 to 0.91; The correlation coefficient among the three factors ranged from 0.75 to 0.89; Posttraumatic stress disorder (PTSD) and partial PTSD cases indicated significantly higher scores than non-PTSD cases. 34/35 in the IES-R-C total score seemed an appropriate cutoff indicative of high levels of sensitivity (0.86), specificity (0.86), and efficiency (0.86) in the broadly defined PTSD-positive groups (PTSD + partial PTSD). Conclusion: the of IES-R-C is a reliable and valid measure for assessing the posttraumatic stress symptoms in Chinese-speaking sample. The IES-R-C may be a useful self-rating diagnostic instrument particularly for survivors with PTSD symptoms as a clinical concern (PTSD + partial PTSD) by using a 34/35 cutoff in total score.
