ABSTRACT
Objective To analyze the changes of Survivin,MSH6 and MSH2 expression in colorectal cancer and explore their relationship with clinical and pathological parameters.Methods 197 cases of colorectal adenocarcinoma and 20 cases of inflammatory intestinal mucosa were detected by immunohistochemistry with Survivin,MSH6 and MSH2,and the correlation between Survivin,MSH6 and MSH2 expression was analyzed.Results In the control group of 20 cases with inflammatory non-tumor intestinal mucosa,the positive expression rate of MSH2,MSH6,Survivin were 95％,95％,10％,respectively.While the positive expression rate of MSH2,MSH6,Survivin were 88.3％,74.1％ and 84.3％ in 197 cases of colorectal cancer.Survivin positive expression rate in colorectal cancer group was significantly higher than that in inflammatory control group (P ＜ 0.05).Survivin expression was correlated with invasion depth and lymph node metastasis in colorectal cancer tissue (P ＜ 0.05),but not with gender,age,tumor size,gross type or degree of differentiation (P ＞ 0.05).MSH2 expression was correlated with tumor size and lymph node metastasis (P ＜ 0.05),but not with gender,age,gross type,depth of infiltration and degree of differentiation (P ＞ 0.05).MSH6 expression was related to gender and lymph node metastasis (P ＜ 0.05),but not to age,tumor size,gross type,infiltration depth and differentiation (P ＞ 0.05).Colorectal cancer tissues showed positive correlation between MSH6 and MSH2 (r =0.326,P ＜ 0.01),positive correlation between MSH2 and Survivin positive expression (r =0.277,P ＜ 0.01),and positive correlation between MSH6 and Survivin positive expression (r =0.435,P ＜ 0.01).Conclusions The positive expression rate of Survivin in colorectal cancer is high.MSH2,MSH6 and Survivin in colorectal cancer play an important role in the development and progression of colorectal cancer,and can provide evidence for the detection of these three factors,including metastasis risk,prognosis assessment and clinical treatment.In particular,Survivin gene may provide evidence for gene therapy.
ABSTRACT
Objective@#To investigate the expression of serum Neurensin 2 (NRSN2) in patients with nasopharyngeal carcinoma (NPC), and to analyze its relationships with epstein-barr virus (EBV) antibody and EBV-DNA.@*Methods@#120 patients with NPC admitted to our hospital from April 2016 to May 2018 were selected as the study group, and 56 healthy people in the physical examination center were selected as the control group. Enzyme linked immunosorbent assay (ELISA) was used to detect the expressions of serum viral capsid antigen-IgA (VCA-IgA), nuclear related tumor antigen-IgA (EBNA-IgA) and early antigen-IgG (EA-IgG). The expression of serum NRSN2 and EBV-DNA were detected by fluorescence quantitative polymerase chain reaction (qPCR). Receiver operating characteristic (ROC) curve was used to analyze the diagnostic value of serum NRSN2 level for NPC. Spearman was used to analyze the relationship between serum NRSN2 and EBV antibody with EBV-DNA in nasopharyngeal carcinoma, multivariate logistic regression analysis was used to analyze the risk factors of NPC.@*Results@#The positive rates of serum VCA-IgA, EBNA-IgA and EA-IgG in the study group were significantly higher than those in control group (P<0.05); the level of serum NRSN2 and the positive expression rate of EBV-DNA in the study group was significantly higher than that in the control group (P<0.05); ROC curves showed that the area under curve (AUC) of serum NRSN2 level in diagnosing NPC disease was 0.759, with sensitivity 63.33%, specificity 80.36%; there were significant positive correlations between serum NRSN2 with VCA-IgA, EBNA-IgA, EA-IgG and EBV-DNA in NPC patients (P<0.05); multivariate regression analysis showed that VCA-IgA, EBNA-IgA, EA-IgG, EBV-DNA and NRSN2 expressions were supportive predictive value for diagnostic NPC (P<0.05).@*Conclusions@#Up-regulation of serum NRSN2 levels in NPC patients is positively correlated with serum VCA-IgA, EBNA-IgA, EA-IgG and EBV-DNA levels, which may provide a reference for the prediction, diagnosis and treatment of NPC.

ABSTRACT
Objective: To study effects of mental health education on mental he alth status of middle school students. Methods:Middle scho ol students from juni or and senior classes were randomly selected for the present study. The mental h ealth education focused on self-confidence、self-improvement、self-discipline. T he effect of education was evaluated by MHT. Results:Both in junior and senior classes, there were clear differences in mental health between the experimental and control conditions. Conclusion: Mental health educatio n pro duced favourable effects on mental health development of middle school students.
