ABSTRACT
Pylorus obstruction caused by foreign bodies in the gastric anrum and granulomatous inflammation is rarely seen.The clinical symptoms of this disease are unspecific.Combination of X-ray radiography,computed tomography and gastroscopy could make definite diagnosis.Differential diagnosis between pylorus obstruction and peptic ulcer,gastric cancer and duodenal obstruction should be done before operation.On April 13,2012,a patient with pylorus obstruction caused by foreign bodies in the gastric anrum and granulomatous inflammation was treated at the Second Hospital of Jiaxing,the imaging characteristics of the disease were summarized to provide referrence for the diagnosis and treatment of this disease.
ABSTRACT
Objective To study the expressions of metadherin (MTDH),E-cadherin and β-catenin in the tissues of hepatocellular carcinoma (HCC),to investigate the relationship between them and the clinical-pathological features,and to evaluate the prognostic values after surgical resection for hepatocellular carcinoma.Methods The protein expressions of MTDH,E-cadherin and β-catenin were studied by immunohistochemistry in tumor tissues of 107 HCC patients who underwent curative surgical resection.The data were correlated with the clinical-pathological data,tumor free time and recurrence rate.Results Positive expression of MTDH and nuclear β-catenin accumulation were correlated with the Edmondson grade (P＜0.05) and decreased E-cadherin expression was correlated with the preoperative serum level of α-fetoprotein (AFP) (P＜0.05).All these expressions were associated with a shorter tumor-free survival and a higher recurrence rate (P＜0.05).Positive MTDH expression was correlated with decreased E-cadherin expression and nuclear β-catenin accumulation (P＜0.05).On Cox regression analysis,MTDH was an independent risk factor of tumour recurrence (RR=3.431,CI=1.254～ 7.318).Conclusions Positive MTDH expression,decreased E-cadherin expression,and nuclear β-catenin accumulation indicated a higher recurrence rate after curative surgical resection for HCC.MTDH was an independent risk factor of recurrence.
