Objective To develop a prediction scale for mental disorders in servicemen, and examine the reliability and validity of this scale. Methods The mental disorders prediction scale was developed by exploring the risk factors inducing the mental disorders. The initial scale included 11 subscales and 102 items. One thousand and four hundreds of soldiers were chosen by random cluster sampling, and tested with this scale, of whom 54 soldiers were tested with Chinese Military Mental Health Scale (CMMHS), 61 with Eysenck Personality Questionnaire (EPQ) at the same time, and 53 were retested after 1 week. The reliability and validity of the scale were examined by Exploratory Factor Analysis and Correlation Analysis. Results According to the results of factor analysis, 11 factors were extracted, named unhealthy defense mechanism, psychosis, depression, personality disturbance, mania, social support deficiency, introversion, family and past history, stressor, neurosis, and growth experience, respectively, and there were 96 items in the formal scale when one lie factor was added. The test-retest correlation coefficients of total scale and subscales were 0.397-0.867 (P

Acute myocardial ischemia and reperfusion led to arrhythmias and increase of glutamic oxalacetic transaminase (GOT),lactate dehydrogenase (LDH),non-csterified fatty acid (FFA) and malondialdehyde (MDA) content, and decrease of superoxide dismutase (SOD) activity in rats. 3, 6-di-methylamino-dibenzopyri-odonium edetate (IHC-72) 5 mg?kg-1 iv significantly reduced the incidence of ventricular tachy-cardia (VT) and ventricular fibrillation(VF) ,shortened the duration of arrhythmias induced by reperfusion, decreased the release of GOT, LDH and FFA, obviously reduced the MDA content,and effectively protected SOD activity in ischemia-reperfused rat hearts. Our experimental results suggested that IHC-72 had protective effects on ischemia-reperfusion injury rat hearts in vivo. The mechanism of the protection might be associated with the inhibition of cellular lipid peroxidation.

BACKGROUND: Xenograft cortical bone is an easy and inexpensive bone graft material, which has good biocompatibility and bio-mechanical properties. As a bone graft, it can function as biological framework for new bone growth and bio-supporting. Moreover, it can also be processed into internal fixation devices.OBJECTIVE: To review the biological properties, preparation methods and clinical applications of heterogeneous cortical bone for fracture fixation.METHODS: A computer-based online search of Pubmed database (1990-01/2009-05) and CNKI (1990-01/2009-05) was performed for related articles with key words of "Xenograft cortical bone, Bone graft, Fixation" in English and Chinese.RESULTS AND CONCLUSION: A total of 128 articles were collected. Xenograft cortical bone has a good biological performance, in particular, a certain degree of bio-mechanical properties. It is not only able to complete bone filling, bone induction, but also function as internal fixator following processing. However, the traditional preparation process reduces their bio-mechanical properties. Heterogeneous cortical bone can be widely used in intra-articular fractures and cancellous bone fracture fixation, and can be self-absorbed, avoiding the second operation. However, its instability limits its initial mechanical properties of fractures at other sites.
