Autoimmunity is influenced by genetic,immune,hormonal,and environmental factors.Viral infections may trigger autoimmunity.It has been established that autoimmunity may be a contributing factor in the pathogenesis of heart disease.Myocarditis is defined as inflammation of the heart muscle associated with impaired function of the myocardium.Myocarditis is considered as the most common cause of dilated cardiomyopathy.Myocarditis may be caused by infectious factors and noninfectious factors,noninfectious factors including autoimmune diseases with myocarditis.To gain a better understanding of autoimmune myocarditis,we summarize the pathogenesis and clinical significance of autoimmune myocarditis.

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.

Joint ligament injury often occurs in basketball sports,therefore,research on characteristics of joint cruciate ligament injury is helpful for the prevention and therapy for joint ligament injury.The manuscript introduces the biomechanical characteristics of knee joint cruciate ligament in the moving state,biological problems involved in repair,as well as the application of artificial ligament in knee joint crucriate ligament injury and its advantages and disadvantages.Various kinds of artificial ligament can be used for the repair of ligament injury,such as polyhexene,poly(ethylene terephthalate),carbon fibers,polyester,polydioxnon,polylactic acid.If we can perfect the artificial ligament,it will be more beneficial to its application in repair of ligament injury.

A Basketball sport is characterized by high exercise intensity, intense antagonism, many physical contacts, and agility. A series of injuries occurs in basketball sports. Tendon adhesion following basketball sports injury is a big problem puzzling athletes for a long time, which affect training and sport technique. 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.

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.

0.05). But male students had higher scores in sexual abuse severity (5.92?2.22) and total abuse severity (30.27?6.8) than girls (5.55?1.34 and 28.87?6.07 respectively, P

Objective: To study the group consultation in preventing psychological disorders causing by retirement.
