Objective　To investigate the validity of the Chinese version of the Symptom Check-List-90 (the SCL-90) in Chinese population. Methods　A total of 624 normal person and 268 out patients were examined with the SCL-90. Results　（1）The internal consistency of the original subscales was found to be good and Cronbach's coefficient alpha ranged from 0.78 to 0.90; （2）Discrimination function analysis based on the 9 original subscales showed that the power of the SCL-90 in discriminating the patients and the community was good with a corrective rate of 80.6%; （3）Factor analysis on the items of the questionnaire yielded a very strong un-rotated first factor which could represent other factors; （4）High inter-correlations were found between the 9 original subscales of the SCL-90 with a correlation coefficient ranging from 0.39 to 0.79. Conclusion　(1) The SCL-90 is acceptable as a research setting and psychiatric screening inventory; (2) The SCL-90 does not have potential as an inventory to distinguish different diagnostic groups; (3) The SCL-90 is not a multidimensional inventory.

An applied anatomical study on the blood supply of the flexor tendon was conducted in the upper extremities of fresh cadaver by means of arterial injection, transparence, maerodissection and histological preparation.The flexor digital tendon can be divided into two parts: non-synovial membrane part and synovial membrane part. The intrinsic vaseularization of non-synovial membrane part of the tendon which was wrapped in paratenon was major in the form of the longitudinal vascular bundles, while the transverse anastomotie branches were short and sparse. The vascularity of this part was simple and uniformly distributed. The intrinsic vascularity of the synovial part possessed distinct characteristics of segmentality and partiality. In the synovial sheath, the blood vessels distributed only onto the dorsal aspect, while the velar 1/3 to 1/2 of the tendon was devoid of vessels. The profundus and superfieialis tendons formed an avascular zone at the proximal interphalangeal and metacarpophalangeal joint separately. It was considered that the difference of the vascularization of tendon might be related to the mechanical force to which the tendon was subjected. The nutrition of tendon was discussed and the selection of tendon graft in the operation was suggested.

Objective To develop a suicide ideation scale for Chinese military.Methods Based on the analysis of literatures and the established ideation scale, the theory structure of suicide ideation scale was constructed and a scale was developed regarding to the results of specialists evaluation.Then 900 soldiers including navy, army and air force were picked out randomly as samples from a military region.The data Was submitted to factor analysis and to test the reliability and validity of the scale.Results The whole suicide ideation scale Was constitute of three factors, such as despair, depression and optimism.Correlation coefficient between each factor and the total score ranged from 0.679 to 0.913,Correlation coefficient between the scale and Suicidal Possibility Scale Was 0.620,the coefficient of stability was 0.904.the Cronbaeh α of each factor ranged from 0.750～0.894.Conclusion The scale proves to be applicable to Chinese military in evaluating their suicidal ideation.

Objective To explore the relationship between cognition and serum cytokines in middle school students with depressive symptoms. Methods The serum levels of interleukin-2 (IL-2), interleukin-6 (IL-6), interleukin-8 (IL-8), and tumor necrosis factor-? (TNF-?) were measured in 49 middle school students with depressive symptoms and 32 normal controls by adopting scales and radioimmunology methods. Results ①The serum levels of IL-2, IL-6, and TNF-? in middle school students with depressive symptoms were significantly lower than those in the controls. ② Serum levels of IL-2, IL-6, and TNF-? in depressive subjects were negatively correlated with the total scores of Beck, Zung and Automatic Thoughts Questionnaire (ATQ), but serum IL-8 levels were positively and significantly correlated with total Beck, Zung and ATQ scores. ③ Serum levels of IL-2, IL-6, and TNF-? were correlated negatively with Beck and ATQ factors. Conclusion Depressive symptoms in middle school students are accompanied by signs of immunosuppression. The immunological mechanisms may be different from the clinical major depression.
