Objective To study the inhibitory effects of GANT61, as an inhibitor of Gli, on the growth of human esophageal adenocarcinoma cell lines OE19 and OE33, and their mechanisms thereof. Methods After treating with different concentrations of GANT61(30,20,13.333 3,8.888 8,5.925 9,3.950 6,2.633 7,1.755 8,1.170 5μmol/L),the cell viabilities of OE19 and OE33 were detected by MTS method, which expressed by IC50. The Gli1and Gli2 mRNA expressions treated with GANT61(10 μmol/L GANT61) or DMSO for 24 h were detected in OE19 and OE33 cell lines by real time fluorescence quantitative PCR. The protein expressions of Gli1, Gli2 and CyclinD1 treated with GANT61 or DMSO for 24 h were detected in OE19 and OE33 cell lines by Western blot assay. Transwell invasion assay was performed to evaluate the inhibiting effect on OE19 and OE33 cell invasion by the treatment of GANT61 or DMSO. Results The IC50 of GANT61 was 8.08μmol/L in OE19 and 9.65μmol/L in OE33 cells. Compared with DMSO group, Gli1 and Gli2 mRNA expressions and Gli1,Gli2 and CyclinD1 protein expressions were significantly decreased in OE19 and OE33 cells of GANT61 group (P<0.05). The number of penetrating cells was significantly reduced in OE19 and OE33 cells of GANT61 group compared with that of DMSO group (P<0.01). Conclusion GANT61 can inhibit the growth and invasion of esophageal neoplasms cells by down-regulating Gli1 and Gli2 mRNA expression,which indicates that Hedgehog signaling pathway may play an important role in carcinogenesis and progression of esophageal adenocarcinoma.

Objective: This study investigates the effect of docetaxel + oxaliplatin + S-1 (DOS program) in treating advanced gastric cancer and surgical safety assessment. Methods: Fifty patients with advanced gastric cancer admitted to the Department of Gastrointestinal Surgery, The Affiliated Tumor Hospital of Xinjiang Medical University between January 2011 and May 2012 were enrolled in this study. These patients were randomized into the observation arm (n=25) and the control group (n=25). The observer group was administered three cycles of chemotherapy using a DOS program before surgical treatment, whereas the control group underwent surgery. Results: Compared with the control group, the clinical response rate (64.0%), D2 lymph node dissection rate (88.0% vs. 64.0%), and R0 resection rate (92.0%vs. 68.0%) in the observation group were significantly higher (P<0.05). Moreover, the number of postoperative lymph node metastasis in the observation group was significantly less than that in the control group (3.2±2.5 vs. 6.3±2.9, P<0.05). The operative time (230.5 min±45.6 min vs. 205.6 min±42.4 min) and intra-operative blood loss (425.5 mL ±115.4 mL vs. 210.6 mL±125.6 mL) of the two groups were sta-tistically significantly different (P<0.05). The incidence of postoperative complications and lymph node sweeping number of the two groups showed no significant difference (19.6 ±2.8 vs. 21.2 ±2.0, P>0.05). The patients exhibited good tolerance to chemotherapy, with bone marrow suppression and gastrointestinal reactions as the main adverse effects. Conclusion:The DOS program is a highly efficient, advanced gastric cancer neoadjuvant chemotherapy. The program can improve patient survival and has good patient tolerance and compliance, good peri-operative safety, high R0 resection rate, and low postoperative lymph node metastasis rate.

Background and purpose: The diagnosis of thyroid papillary carcinoma sometimes is difficult, metastasis of lymph node is the major reason of local relapse and influence prognosis.This study explores the immunohistochemical expression and their diagnostic value of CK19,HBME-1,galectin3,p27 and cyclinD1 in thyroid papillary carcinoma and the relations between p27,cyclinD1 and lymph node metastasis of papillary carcinoma.Methods: Immunohistochemical staining was used on 50 specimens of benign lesions (40 speciments of nodular goiters and 10 cases of follicular adenomas) and 50 specimens of papillary carcinomas (40 specimens of classic variants and 10 specimens of follicular variants) operated in our hospital from January of 2005 to December of 2008. Results: CK19,HBME-1 and galectin3 were expressed in cytoplasm or on the membrane, but p27 and cyclinD1 were expressed on the nucleus. The expressions of CK19,HBME-1 and galectin3 in thyroid papillary carcinoma were middle to strong positive, the positive ratios were 100%,96% and 100%, respectively;their expressions in benign lesions were negative or low positive, the positive ratios were 10%,10% and 6%, respectively;there were statistical differences between them (P<0.01). The expression of p27 in thyroid papillary carcinoma was low positive or negative, the positive ratio was 14%, but the expression of p27 in benign lesions was middle to strong positive, the ratio was 84%, there was also significant difference between them(P<0.01). The expression of CyclinD1 were similar in benign and malignant lesions of thyroid, the positive ratios were 68% and 78%, respectively, there was no statistical difference between them(P>0.05). There were significant differences(P<0.01) between the benign lesions and the papillary carcinomas in terms of the combination of CK19,HBME-1 and galectin3 expression and there were no significant differences(P>0.05) in the group of the former with underexpression of p27 between the two groups. The differences were not statistically significant (P>0.05) between the underexpression of p27 with the expression of cyclinD1 (the positive ratios in metastasis group and no metastasis group are 72.7% and 71.4%) in the lymph node metastasis. Conclusion: The combined immunohistochemical stainings of CK19,HBME-1 and galectin3 are useful on the diagnosis and differential diagnosis of thyroid papillary carcinoma, there is no predicted value of the underexpression of p27 with the expression of cyclinD1 for lymph node matastasis of thyroid papillary carcinoma.

Objective: To analyze the prevalence of obesity and its influencing factors among residents aged 40 years and over in Taizhou,so as to provide reference for obesity prevention and control. Methods: From June 2014 to May 2015,people who were aged 40 years or above and received routine physical examination in six centers for disease control and prevention in Taizhou were recruited. Demographic characteristics and health relates behaviors were collected by a questionnaire survey;height,weight,waist circumference and hip circumference were collected by physical examination. Logistic regression analysis was conducted to explore the influencing factors for overall obesity and central obesity. Results : Totally 1 216 people were investigated,and 1 192 (98.03%) questionnaires were valid. The age of them ranged from 40 to 86 years old,with （51.92±8.91） years old on average. There were 547 males （45.89%） and 645 females （54.11%）. The prevalence rates of overall obesity and central obesity were 6.54% and 60.32%,respectively. The Results of multivariate logistic regression analysis showed that regular physical exercise （OR=0.597, 95%CI： 0.359-0.992） was a protective factor for overall obesity;female （OR=2.352,95%CI： 1.685-3.283）was a risk factor of central obesity;public servants or staff from enterprise and institution（OR=0.508, 95%CI： 0.289-0.892）,drinking （OR=0.637,95%CI：0.471-0.860）,salt intake of less than five grams per day （OR=0.590,95%CI：0.434-0.802）and regular physical exercise （OR=0.760,95%CI：0.583-0.991） were protective factors for central obesity. Conclusion The prevalence rates of overall obesity and central obesity among residents aged 40 years or above in Taizhou were 6.54% and 60.32%, respectively. Gender,occupation,drinking,salt intake and physical exercise were the influencing factors for obesity.

OBJECTIVETo investigate the treatment methods and prognostic factors of high-risk gastrointestinal stromal tumor (GIST).

METHODSClinicopathological date and follow-up data of 108 patients with high-risk GIST from January 2002 to February 2016 treated at our department were retrospectively reviewed. The patients were divided into two groups according to whether they received adjuvant therapy after surgery. A group of patients received imatinib adjuvant therapy(adjuvant therapy group, 69 cases). Another group of patients were not treated with imatinib until they were found to have disease progression(follow-up observation group, 39 cases). The survival rate and recurrence rate were compared between two groups, and the risk factors of prognosis were analyzed by Cox regression model.

RESULTSAll the cases were followed up with a median time of 48 months(1 to 161 months). Recurrence and / or metastasis occurred in 57(52.8%) patients during follow-up. The postoperative recurrence and / or metastasis rate was 34.8%(24/69) and 84.6%(33/39) respectively in the adjuvant therapy group and the follow-up observation group, the difference was statistically significant(P=0.000). Twenty-eight(25.9%) patients died. The 1-, 3-, 5-, 10-year survival rates of the 108 patients undergoing follow-up were estimated to be 99.8%, 87.7%, 76.0% and 42.7% respectively. The 5-year survival rates were 79.3% and 72.3% in the adjuvant therapy group and the follow-up observation group, the difference was not statistically significant (P=0.648). Univariate analysis showed that mitotic count, radical degree and tumor rupture were predictive factors of survival after resection of primary high-risk GIST (all P<0.05). Multivariate analysis using Cox regression model revealed that the mitotic count (P=0.013, RR=2.400, 95%CI:1.206 to 4.779) and radical degree(P=0.003, RR=3.968, 95%CI:1.609 to 9.784) were independent prognostic factors.

CONCLUSIONComprehensive treatment of radical surgery combined with targeted therapy and close followed up can lead to better long-term survival of high-risk patients with GIST.
