Stathmin, a ubiquitously expressed cytosolic protein(Mr=19×10~3), is also called oncogene protein 18 (Op18). Stathmin is involved in the assembly of microtubule (MT) and spindle by binding the tubulin protein. It plays a key role in cell proliferation, differentiation, regeneration, and migration and has regulatory effects on the signal transduction. Recently, it is reported that stathmin is overexpressed in a variety of human malignancies. It induces tumor cell migration and invasion by regulating MT depolymeri-zation. Its post-translational modification influences the interaction with p53 protein and is involved in the initiation and progression of malignant tumor. Stathmin alone or in combination with chemotherapeutics has been used for tumor therapy. The internal association of stathmin with cancer etiology is still unknown. So, further studies are needed to determine the role of stathmin as potential tumor biomarker and a drug target in tumor therapy.

OBJECTIVE: To investigate the changes of neuropeptides content in a rat model of spleen-deficiency syndrome. METHODS: Rats were randomly divided into three groups: normal group, untreated group and treatment group. There were ten rats in each group. Spleen-deficiency syndrome was induced by intragastrically administration of rhubarb concentrate in rats of the untreated and treatment group. The rats in the treatment group were intragastrically administered with Sijunzi decoction, a traditional Chinese compound herbal medicine for strengthening spleen and supporting qi. Normal saline was intragastrically administered to the rats in the normal and untreated groups. The somatostatin (SS) and cholecystokinin-8 (CCK-8) content in hypothalamus and colons was detected by the method of radioimmunoassay and the D-xylose content in urine was also detected. RESULTS: The CCK-8 content in hypothalamus of the untreated group was higher than that of the normal group (P<0.05). SS and CCK-8 content in colons of the untreated group was higher than that of the normal group (P<0.05). The CCK-8 content in colons of the untreated group was lower than that of the treatment group (P<0.05). The excretion rate of D-xylose in the untreated group was lower than that of the normal group (P<0.05). CONCLUSION: The disorder of neuroendocrine regulation in rats with spleen-deficiency syndrome may be chiefly responsible for "spleen-deficency and dysfunction of spleen" in traditional Chinese medicine.

Objective To investigate the value of video-assisted thoracoscopic surgery(VATS)in the treatment of coagulated hemothorax.Methods A prospective randomized controlled study.Between July 2005 and July 2007,62 patients with coagulated hemothorax were enrolled in this study.The patients were randomly divided into VATS and traditional thoracotomy groups(31 in each).The pathophysiological parameters of the two grups were compared.Results No significant difference in the sex,age,property and location of the wound,and rate of complicated injuries was noticed between the two groups.The mean operation time,duration of postoperative drainage,and postoperative hospital stay of the VATS group were significantly shorter than those in the traditional group [(52.1?24.4)min vs(120.2?47.2)min,t=-7.136,P=0.000;(1.7?0.7)d vs(4.8?1.8)d,t=-8.937,P=0.000;and(12.6?2.4)d vs(18.0?8.9)d,t=-3.262,P=0.002;respectively];and the mean intraoperative blood loss and the volume of thoracic drainage of the VATS group were significantly lower than those in the traditional group [(137.1?14.6)ml vs(203.2?53.4)ml,t=-6.648,P=0.000;and(181.3?37.9)ml vs(253.9?64.0)ml,t=-5.435,P=0.000,respectively].No significant difference in the rate of complications existed between the two groups(0 vs 1 case,?2=0.000,P=0.000).Conclusion Video-assisted thoracoscopy is feasible and safe for coagulated hemothorax and is worth being widely used.

Objective To explore the effects of psychological health education on mental health status of middle school students. Methods All middle school students were randomly divided into 2 groups by cluster sampling, a interventional group and a control group. 28 students in the intervention group received group psychological consultation for two months, 30 students in the control group received no therapies.Changes of active respond and negative response subscales(ARNRS), communication anxiety scale (IAS),accommodate others scale(AOS), self-rating depression scale(SDS)were compared before and after the intervention in both groups. Results After group counseling, ARNRS, IAS, AOS, SDS in the interventional group was significantly changed compared with both pre-counseling and the control group, with P<0.05～0.0001 and P<0.05～0.0001, respectively. Conclusion Community mental health education can enhance middle-school student's psychological health level.

Objective: 1)To revise the Social Skills Scale (SSS) and examine its psychometric properties.2) To explore the relationship between SSS and mental health. Methods:1)A sample of 394 freshmen completed the Social Skills Scale, SCL-90, and Self Consistency and Congruence Scale. Exploratory factor analysis, item analysis, reliability and validity analysis were used to revise the Social Skills Scale. 2) The relations between the SSS , SCL-90 and Self Consistency and Congruence Scale were examined.Results:Using exploring factor analysis, 5 factors were extracted, i.e. social adaptation, social perception, social confidence, social expression, and impression management. The mean inter-item correlation coefficients ranged from 0.52 to 0.77. The correlation coefficients of item and corresponding subscale ranged from 0.52 to 0.77, and the item discrimination indexes ranged from 0.32 to 0.52. Social adaptation, social perception and impression management were positively correlated with mental health. Social confidence was negatively correlated with mental health. Social expression did not correlation with mental health. Conclusion:The revised Social Skills scale was an reliable and valid measurement.

BACKGROUND: Mental disorders of college students, especially medical college students, deteriorate year by year.Mental disorders can not only restrict healthy development of body and mind, but also cause social crisis.OBJECTIVE: To survey the prevalence of mental status and the correlation between mental status and family dynamics among medical college students.DESIGN: Randomized cluster sampling.SETTING: Center of Mental Health, the First Affiliated Hospital, Chongqing University of Medical Science.PARTICIPANTS: A total of 801 sophomores were selected from a medical university of Chongqing from November 2004 to June 2005.METHODS: ① Symptom Checklist-90 (SCL-90) was used to evaluate mental status among college students. If those students whose total scores were ≥ 200 and/or the score of any factor in SCL-90 was ≥ 3, they were regarded as having mental problem. The higher the scores were, the severer the mental problemwas. ② Family dynamics questionnaires, including family atmosphere, individuation, systemic logic and disease opinion, were used to evaluate characteristics of family dynamics. There were 4 items: family atmosphere, individuation, systemic logic and disease opinion. The more comfortable and cheerful the family atmosphere was, the lower the scores were; the greater the differentiated degrees were, the lower the scores of individuation were; the more objective the disposal of problems was,the lower the scores of systemic logic were; the more subjective the duty of recovery was, the lower the scores of disease opinion were.MAIN OUTCOME MEASURES: ① Prevalence of mental disorder; ② comparing scores of family dynamics between disorder group and normal group; ③ results of correlation analysis and step regression analysis between mental disorder and family dynamics.RESULTS: Among 801 questionnaires, 747 were involved in the final analysis. ① Prevalence of mental problem was 19.4%. ② The scores of family atmosphere, Individuation, systemic logic and disease opinion were all higher in disorder group than those in normal group, with significant differences (3.10±0.49, 2.66±0.64; 2.92±0.54, 2.77±0.58; 2.79±0.55,2.69±0.54; 2.58±0.67, 2.36±0.62, P ＜ 0.05). ③ The total score of SCL-90 was positive correlation with points of family atmosphere and disease opinion (r=0,184, 0,156, P ＜ 0.05). Family atmosphere, individuation and disease opinion were analyzed by regression equation.C0NCLUSION: Mental status of college students is closely related to family dynamics. Family atmosphere and disease opinion play a great role in mental disorder.
