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 Established the model of atherosclerosis (AS) cells.To explore Hydrogen sulfide donor (NaHS) in atherosclerosis model by oxidized low density lipoprotein (ox-LDL) induced of the NF-κBp65 factor expression.MethodsApplication concentration of 80ug/mL ox-LDL induced liver cancer cell HepG2 cells AS model, set up a control group and treatment group (10μmol/L、15μmol/L、30μmol/L、100μmol/L、500μmol/L、1000μmol/L), to observe hydrogen sulfide this cell model of the cell proliferation activity and the determination of TNF-α and IL-10 factors of the expression, through the RT-qPCR and Western-blot method for determining the expression of the NF-κBp65 expression situation.ResultsAt 24h the ox-LDL induced a large number of red-stained granules, free cholesterol and total cholesterol in HepG2 cells increased, and free cholesterol content was more than 50% of total cholesterol in HepG2 cells, indicating that AS cell model was established successfully.CCK8 method of cell proliferation activity test results showed that the NaHS in 30umol/L, duration of 48 h when the largest cell proliferation activity.The TNF-α cytokine by ELISA method for testing the results showed that the treatment group in 15umol/L and 30umol/L concentration compared with the control group decreased significantly (P<0.05), while the expression of IL-10 increased significantly (P<0.05), with statistical significance.RT-qPCR and Western-blot method results show that the NF-κBp65 factor expression significantly reduced compared with control group (P<0.05), with statistical significance.ConclusionH2S play a protective role in atherosclerotic lesions by reducing the NF-κBp65 factor expression, and provide a valuable reference for the development and clinical treatment of H2S donor-type drugs.

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 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.

Fifteen cases of malignant melanoma,17 cases of acquired nevus,18 cases of congenital small nevus,and 3 cases of congenital giant nevus were labeled with anti-human prolifera-tive cell antibody Ki-67 with ABC labeling method.It was found that 13 out of the 15 cases of malignant melanoma were positive and the positive rate of the tumor cells was ranged between 2% to 33%.After culture,the positive rate of the melanoma cells was 88%.But all the 3.types of melanocytic nevi were negative.The findings suggest that the labeling of anti-human proliferative cell antibody Ki-67 is a sensitive and specific method to identify melanocytic tumors and it is not sensitive enough to differentiate the minor changes of the 3 types of nevi.

To construct a cDNA subtractive library of genes transactivated by hepatitis C virus core protein with suppression subtractive hybridization technique. mRNA was isolated from HepG2 cells transfected with pcDNA3 1(-)-core and pcDNA3 1(-) empty vector,respectively, then cDNA was synthesized. After restriction enzyme RsaI digestion, small sized cDNA were obtained. Then tester cDNA was divided into two groups and ligated to the specific adaptor 1 and adaptor 2, respectively. After tester cDNA was hybridized with driver cDNA twice and underwent two times of nested PCR, and then it was subcloned into T/A plasmid vectors to set up the subtractive library. Amplification of the library was carried out with E.coli strain JM109. The cDNA were sequenced and analyzed in GenBank with Blast search after PCR. The subtractive library of genes transactivated by HCV core protein was constructed successfully. The amplified library contained 233 positive clones. Colony PCR product showed that 213 clones contained 100~ 1 000 bp inserts. Sequence analysis was performed in 63 clones. Six of the sequences were unknown genes before. The full length sequences were obtained with bioinformatics method,which had been accepted by GenBank. It suggested that six novel cDNA sequences might be target genes transactivated by HCV core protein.
