Objective To explore the clinical expression of P53, Livin and PARP in the epithelial ovarian cancer and its correlation with the chemotherapy resistance and clinical prognosis.Methods 74 specimen of epithelial ovarian cancer confirmed from January 2009 to June 2011 in our gynecology department were selected.During the follow-up visit, the subjects were divided into chemotherapy sensitivity group and chemotherapy resistance group according to the recurrence cases, the clinical expression and survival rate for two groups were compared, the influence factors of survival time were analyzed.Results The positive rate of P53, Livin and PARP for chemotherapy sensitivity group was 47.1%, 56.9%and 52.9%;the positive rate for chemotherapy resistance group was 73.9%, 95.7% and 95.7%,the diyforences were significant(P<0.05).After 1, 3 and 5 years of treatment, the survival rate for chemotherapy sensitivity group was 100.0%, 82.4% and 66.7%,The survival rate for chemotherapy resistance group was 87.0%, 26.1% and 8.7%,the diyforences were significant(P<0.05).Based on the Cox regression model, the influence factors of the patient's age, pathological differentiation degree, clinical staging and chemotherapy sensitivity were introduced.It was known that the patient's survival time was greatly influenced by clinical staging and chemotherapy sensitivity (P<0.05).Conclusion For patients with epithelial ovarian cancer, the expression of P53, Livin and PARP is correlated with chemotherapy resistance.Therefore, the clinical effect is predictable, for patients with higher expression, the personalized therapy can improve the patient's prognosis.

Objective To analyze the effects of health management of metabolic syndrome on the control of related risk factors. Methods A total of 430 patients diagnosed with metabolic syndrome in 2008completed questionnaire and before randomly assigned to the health management group ( n = 207 ) and the control group (n=223). One year later, all the participants were investigated for the risk factors of food intake, cigarette smoking, alcohol consumption, staying-up and emotion, and the changes of body mass index ( BMI), blood pressure ( BP), triglyceride (TG), high-density lipoprotein cholesterol (HDL) and fasting blood glucose (FBG). Student's t test and x2 test were used for data analysis. Results For the health management group, the incidence of high-salt, high-fat and high-sugar intake, overtake of food, lack of physical exercises,staying-up and alcohol drinking was significantly decreased at 1 year (P ＜ 0. 05 ), when compared with baseline and the control group ( both P ＜ 0. 05 ). For the health management group, BMI,systolic blood pressure (SBP),TG and FBG was improved at 1 year (P＜0. 05). In comparison with the control group, BMI, SBP, diastolic blood pressure (DBP),TG and FBG of the management group were significantly improved (P ＜ 0. 05 ). Conclusions Patients with metabolic syndrome may have better treatment compliance after receiving systematized and individualized health management.

Objective To observe the ultrastructure and absorption function of colon mucosa in rat with ultra-short bowel syndrome. Methods Totally 30 SD rats were randomly divided into three groups: ultra-short bowel group (90%-95% of the intestine was surgically resected, n = 10), sham group (n = 10), and normal control group (n = 10). All animals were given with enteral nutrition. Scanning electron microscopy was performed 21 days later to observe the morphology of mucosal surface, and transmission electron microscopy was performed to observe the ultrastructural changes of intestinal epithelial cells. The absorption of colon to water, carbohydrates, and amino acid determined after 3 hours of closed perfusion of the colon with D-xylose solution and 15N-glycine on the continuous cycle of colon. Results As shown by the transmission electron microscopy, compared with the normal control group, rats in the ultra-short bowel group showed significantly decreased goblet cells on colonic mucosl surface, increased epithelial cells, longer and denser microvillus, increased area of membrane surface, increased number of cell-cell junctions, increased number of desmosome, tight junction, and gap junctions, higher development of endoplasmic reticulum and dictyosome, and increased number of mitochondria. As shown in the screening electron microscopy, compared with the normal rats, rats in the ultra-short bowl group had significantly deeper colon folds, thicker mucous membrane, increased number of bay openings, and longer and denser microvillus-like structures inside bays. The capability of water absorption was signicatnly higher in the ultra-short bowl group than in the sham group and normal control group (P = 0. 000) . The absorption rates of xylose and 15 N-glycine were also significantly higher in the ultra-short bowl group than in the control group (P ＜ 0. 01). Conclusions The absorption capability can be compensatively increased in rats with ultra-short bowel syndrome. Decreased apoptosis of colon mucosa cells, increased absorption cells, hyperplasia of microvilli, increased area of the membrane surface,and increased number of mitochondria may constitute its material and energy bases.

Objective To investigate health status of primary or middle school teachers. Methods A total of 4482 physical examination results of the teachers from Qiaokou District of Wuhan in 2008 were compared with 5526 data obtained in 2006. The rate of healthy to unhealthy participants was evaluated. The overall and age-specific disease incidence, including overweight, hypertension, hyperlipidmia, hyperglycemia,liver dysfunction, abnormal EGG, concrement, adiposis hepatica, and HBV infection, was recorded. X2 test was used for statistical analysis. Results Abnormal examination results were more common in 2008 when compared with those in 2006( X2 = 28. 35, P ＜ 0. 05 ). The incidence of hypertension was descended ( X2 =4. 51 ,P ＜ 0. 05 ), although the rates of hyperlipidimia, hyperglycemia, liver dysfunction, abnormal ECG,concrement, and adiposis hepatica were increased in 2008 ( P ＜ 0. 05 ). The incidence of hyperlipidimia, liver dysfunction, abnormal ECG, and adiposis hepatica increased in all age groups ( P ＜ 0. 05 ). The incidence of hyperglycemia and concrement increased in those ＞ 35 years old ( P ＜ 0. 05 ). Conclusion Except for hypertension and HBV infection, the incidence of common diseases has been increased in the young and middle-aged teachers during the last 2 years. Thus the health management for the primary or middle school teacher should be improved in the future.

AIM: To examine the effect of insulin on the proliferation of human hepatocellular carcinoma cell and its possible mechanisms. METHODS: The human hepatocellular carcinoma cell line(HepG-2) was used to study the changes in calcium ion across plasma membrane (Ca 2+ APM)under the action of insulin by the assay of atomic absorption spectrum, and in the proliferation under the action of insulin and calcium ion antagonist (isoptin). RESULTS: The influx of Ca 2+ APM and the proliferation was increased after insulin administration, but the proliferation was inhibited by isoptin. CONCLUSION: Changes in the homeostasis of calcium ion across plasma membrane was involved in the effect of insulin on the proliferation of human hepatocellular carcinoma.

AIM: To explore the effects of PMA(phorbol-12-myristate-13-acetate,a tumor promoter, mimicking the action of diacylglycerol on PKC)and laminin on the adhesion and the proliferation of human hepatocellular carcinoma cells, and provide a new clue to liver cancer treatment. METHODS: Human hepatocellular carcinoma cell line(BEL-7402)was used to identify the endogenous laminin and protein kinase C-?(PKC-?) expression, and the effects of laminin and PMA on the adhesion and the proliferation were also investigated in vitro. RESULTS: By the effect of exogenous laminin, human hepatocellular carcinoma cell (BEL-7402) possessed endogenous laminin expression and increased the adhesion and the proliferation, which was showed the synergistic action by the effect of PMA in combination. By the action of PMA alone,the proliferation and the PKC-? expression increased by exogenous laminin were decreased, and the adhesion and the endogenous laminin expression were increased. CONCLUSIONS: The finding suggested that the adhesion and the proliferation of human hepatocellular carcinoma cell were closely related to the effects of endogenous or exogenous laminin ,which were associated with cPKC-? activity. Therefore,the application of anti-laminin antibody in combination with PKC antagonist might be a new clue to find out the therapy for liver cancer.

Triage is one of the important taches for the wounded whom is cured effectively under the condition to limited medical resource in public health emergency events.It is a decision based on doctrine rather than expediency.By the view of ethics,the article considered three doctrines: fairness,benthamism and scientific decision-making,which assures that the outcome of wartime triage at the sea is speedy and exact.
