Objective To explore the expression and clinical significance of two oncogenes,CerbB-2 and p53,on cervical squamous carcinoma.Methods The immunohistochemical S-P process was performed on 45 cases of cervical squamous carcinoma.The expressions of CerbB-2 and p53 on 15 cases of CIN(cervical intraepithelial neoplasia)and on 10 cases of normal cervical tissues were chosen and the relationship between the expressions and the related clinicopathological factors were analyzed.Results The positive expression rate of CerbB-2 on normal cervical tissues, CIN and cervical squamous carcinoma was 0,26.7% and 66.7%, respectively; that of p53 was 0,13.3% and 68.9% ,respectively.From the normal cervical epithelium to the CIN and to the cervical squamous carcinoma,the positive rate of CerbB-2 and p53 was increased significantly(P<0.05);the positive rate of CerbB-2 was associated with the pathological grade and the metastasis of lymph node(P <0.05) and that showed no statistic significance with the clinical stage ,the diameter of tumour,the infiltration of vessel and infiltrative depth(P > 0.05) ;the positive rate of p53 is only associated with the pathological grade(P <0.05) ;the difference between the CerbB-2 and p53 expressions on cervical squamous carcinoma were not statistically significant(P> 0.05).Conclusion The expressions of CerbB-2 and p53 have some practical values on the occurrence, the development and the clinical prognostic evaluation for the cervical squamons carcinoma.

Objective To investigate the expression and clinical significance of CDx2 and hepatocyte antigen(Hep) in gastric carcinoma.Methods The expression of CDx2 and Hep in 9 cases of nomal gastric mucosa,15 cases of small intestinal mucosa,8 cases of colon mucosa,15 cases of intestinal metaplasia of the stomach and 130 cases of gastric carcinoma were detected with immuohistochemical EnVisionTM Systems measures.Results The positive rates of CDx2 expressed in the nomal gastric mucosa were 0,small intestinal mucosa 80%(12/15),colon mucosa 87.5%(7/8),intestinal metaplasia of the stomach 86.7%(13/15),gastric carcinoma 37.7%(49/130);The positive rate of Hep was 11.1%(1/9),86.7%(13/15),12.5%(1/8),100%(15/15),55.4%(72/130) respectively.There was much higher positive expression of CDx2 in intestinal-type carcinoma than in diffuse-type gastric carcinoma(P

Objective To study the diagnosis and treatment of synchronous gastric cancer and gastric stromal tumor in 18 cases. Methods Clinical data of 18 cases of synchronous occurrence of gastric cancer and gastric stromal tumor from January 1996 to December 2009 were analyzed retrospectively.Results Clinical features of all cases were atypical. There was 1 case diagnosed preoperatively, 3 cases diagnosed intraoperatively and 14 cases diagnosed postoperatively. The mean size of gastric cancer and gastric stromal tumor was (3.3±2.3) cm and (0.9 ±0.5) cm respectively. There were 16 cases of gastric stromal tumor in low risk of malignance and 2 cases in moderate risk of malignance. All cases were operated without complications and the 1-year, 3-year and 5-year overall survival rate was 88.2%, 63.2% and 36. 1% respectively. Conclusions Clinical features of synchronous occurrence of gastric cancer and gastric stromal tumor are atypical, in this series most gastric stromal tumors are in early stage and of low risk of malignance. The prognosis of patients with synchronous occurrence of gastric cancer and gastric stromal tumor mainly depends on gastric cancer.

ObjectiveTo explore the expression of Glut1, HIF-1α and Ki-67 in hepatocellular carcinoma (HCC) and their relationship between their expression and clinicopathological features.MethodsImmunohistochemical study (EnVision method) for Glut1, HIF-1a and Ki-67 were performed on tissue microarray which consisted of 171 cases of HCC, 55 cases of adjacent non-neoplastic liver tissues, and 22cases of normal liver tissues.ResultsThe expression rate of Glut1 ,HIF-1α and ki-67 in 171 cases of HCC was 15.2％, 19.9％ and 66.1％, respectively, which was much higher than that in the adjacent non-neoplastic liver tissues (1.8％ ,1.8％and 5.5％) and normal liver tissues(all negative).The expressions of Glut1 and HIF-1α were positively correlated with the differentiation degree of HCC and TNM stage(P ＜0.01, P ＜0.05).The expression of ki-67 was positively correlated with the differentiation degree of HCC.There was a significant positive correlation between the expressions of Glut1 and HIF-1α in HCC (r1 =0.553, P ＜0.05), the expressions of Glut1 and HIF-1α were positively correlated with ki-67(r2 =0.560,r3 =0.613, P ＜0.05).ConclusionsGlut1, HIF-1α and ki-67 may play a role in the tumorigenesis and progression of HCC in some degree.Combined detection of Glut1, HIF-1α and Ki-67 may be helpful to judge the degree of malignancy and potential metastasis and evaluate the prognosis.

Objective:To investigate the correlation between the enhancement characteristics in arterial phase and the prognosis of patients with massive intrahepatic cholangiocarcinoma (IMCC).Methods:The imaging and clinical data of 92 patients with IMCC who were pathologically confirmed and underwent enhanced MRI or CT in Central Hospital of Lishui from June 2004 to February 2019 were retrospectively analyzed. According to the enhancement pattern of the primary lesion in the arterial phase, patients were divided into rich arterial blood supply group （17 cases） and deficient arterial blood supply group （75 cases）. The clinical data and imaging features of these patients were studied. Differences between measurement data and count data between the two groups were compared using t test and Fisher test. Kaplan-Meier analysis and log-rank test were used to analyze overall survival. The Cox regression multivariate analysis was used to study the relationship between the variables and the risk of death. Result:The enlargement of lymph nodes, long diameter of the primary lesion, CA19-9, treatment and HPD around the primary lesion in arterial phase were statistically different in the two groups ( P<0.05), others were no statistical difference. CA19-9>200 U/ml, lymph node enlargement, HPD around the primary lesion in arterial phase and deficient arterial blood supply were independent factors for the prediction of prognosis in IMCC patients with surgery ( P values were 0.008, 0.002, 0.049 and 0.005, respectively). Lymph node enlargement and deficient arterial blood supply were independent risk factors for the prediction of prognosis in IMCC patients with surgery ( P values are 0.049 and 0.045, respectively). Conclusion:The blood supply characteristics of arterial phase are independent factors for the prognosis of patients with IMCC.
