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 investigate the clinical effects of gastric bypass( GBP) on type 2 diabetes mel-litus(type 2 diabetes mellitus, T2DM)patients with different body mass index(BMI).Methods T2DM patients undergoing GBP from Sep.2012 to Jul.2013 were divided into 2 groups:obese group( BMI≥28 kg/m2 , 16 ca-ses)and overweight group(BMI<28 kg/m2,21 cases).Changes of fasting plasma glucose(FPG), insulin resist-ance index(HOMA-IR)and insulin stimulation release(INS), C peptide release, BMI, glycosylated hemoglobin ( HbA1c) at 3 and 6 months after surgery were observed.Results INS and C peptide improved 3 months after surgery(P<0.05),and they were close to normal at 6 months after surgery.HbA1c significantly decreased 3 months after surgery compared with that before surgery( P<0.05) and it was close to normal at 6 months after sur-gery.Patients in obese group had significantly declined weight 3 months after surgery compared with that before surgery, and reached the steady state 6 months after surgery.15 cases(93.7%) in the obese group had BMI<25 kg/m2 , and the difference had statistical significance ( P<0.05 ) .Patients in the overweight group had their weight declined but no statistical difference was found(P>0.05).Blood sugar in the obese group decreased with different degrees at 3 and 6 months after surgery.The effective rate was 92%for the obese group and 78%for the overweight group.The overall effective rate was 90%.Conclusion GBP has significant therapeutic value for T2DM patients with different BMI, especially for patients in obese group, which is worth of clinical promotion.

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.

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 study the features of esophageal motility in the cases with myasthenia gravis(MG).Methods 15 healthy controls and 45 patients with MG were tested by using a low-compliance four-lumen hydraulic infusion system,respectively.Focused on the following parameters:PP,UESP,UEP,MEP and MERP.Results There were significant differences of the parameters in between MG cases and healthy controls PP (73.24 ± 31.40) mmHg (1 mmHg =0.133 kPa) vs.(103.78±29.47) mmHg,P=0.002;UESP(41.75 ±21.04) mmHg vs.(60.59 ±17.97) mmHg,P=0.003;UEP (56.63 ±30.26) mmHg vs.(78.98 ±30.14) mmHg,P =0.016;MEP(53.96 ±23.25) mmHg vs.(75.11 ±23.75) mmHg(P =0.004).However,MERP of MG cases or healthy controls seemed to be similar[(-7.76 ± 5.94) mmHg vs.(-7.58 ± 5.76) mmHg,P =0.91).Additionally,the above-mentioned parameters in the cases with generalized myasthenia gravis or dysphagia were significantly different compared with other subtypes or healthy controls (P ＜ 0.01).However,there were no significant differences of the parameters in between ocular MG and healthy controls,or in between MG with and without thymoma.Conclusion The upper and middle part of esophageal motility dysfunction is very common in MG cases,especially in those with dysphagia or generalized MG,characterizing by the declined pressure.Manometry in MG cases can help us classify the subtypes of MG and verify their esophageal motility functions.

Objective To establish differential protein expressing profiles of human gastric adenocarcinoma cell in primary or metastatic lymph node tissues by two-dimensional differential gel electrophorosis (2-D DIGE) so as to investigate the metastatic molecular mechanism of the gastric cancer.Methods After obtaining 6 samples of human primary gastric cancer and metastatic lymph node tissues,with manual no-staining frozen sections microdissection,human gastric adenocarcinoma cells from primary or metastatic lymph node tissues were isolated,and then the total proteins were extracted and purified.Highly sensitive 2-D DIGE was used to separate the total protein differentially expressed in the cells.The proteins were visualized by using a fluorescence scanner at appropriate wavelengths for Cy2,Cy3 and Cy5 dyes (Typhoon 9400).Image analysis was carried out with the DeCyder-Differential analysis software (Biological Variation Analysis version 5.0).Results Not only can the study procure defined adenocarcinoma cell populations from gastric primary or metastatic lymph node tissues,but also can resolve the problem of the change in 2-D DIGE patterns because of the varying in protein changes owing to dyeing.All these showed that the technique was simple,easy to perform,versatile and of particular usefulness when laser capture microdissection (LCM) was practically unavailable.The 2-D DIGE patterns with high resolution and reproducibility from adenocarcinoma cells in gastric primary or metastatic lymph node tissues were obtained.The number of spots in Gel1,Gel2 were 1 416 (similar 1 062,decrease 277,increase 77),1 299 (similar 1 050,decrease 157,increase 92),respectively.A total of 11 differential proteins were acquired by image analysis with DeCyder-Differential analysis software (Biological Variation Analysis version 5.0).Conclusions In this report,a simple,easy to proform method of protein epuration,manual no-staining frozen sections microdissection is described,and have used the highly sensitive 2-D DIGE for the identification of proteins differentially expressing in human gastric adenocarcinoma cells from primary or metastatic lymph node tissues.These results provide a fundamental basis for further study of metastatic mechanism of gastric cancer and screen its specific markers.
