ABSTRACT
Objective To explore the expressions ofβ-catenin in gastric adenocarcinoma primary tumors and metastatic lymph nodes,and to determine if it is associated with infiltration degree and whether it can provide the basis for gastric cancer metastasis.Methods The expressions ofβ-catenin were detected in 156 patients with gastric adenocarcinoma specimens,40 cases with the corresponding lymph nodes and 12 cases of normal gastric tissues by the method of immunohistochemistry.The expressions ofβ-catenin in gastric adenocarcinoma and corre-sponding lymph node metastases were analysed.The relationship between the expression of β-catenin and the clinical pathological features of gastric adenocarcinoma was ascertained,and difference between them was observed.Results The positive expression rate ofβ-catenin in normal gastric tissue membrane was 100.0%(12/12).The expression rate ofβ-catenin was 29.5%(46/156)in adenocarcinoma cell membrane,and it was 10.0%(4/40)in metastatic lymph nodes cell membrane.The positive expression ofβ-catenin was not associated with patient′s age(χ2 =2.160,P=0.142),gender (χ2 =1.229,P=0.268),but it was associated with tumor infiltration degree (χ2 =4.032,P=0.045 ),degree of tumor differentiation (χ2 =6.093,P=0.048),tumor stage (χ2 =4.591,P=0.032),and metastasis lymph nodes (χ2 =4.485,P=0.034).The incidence of abnor-mal or loss expression ofβ-catenin in gastric adenocarcinoma metastatic lymph nodes was higer than that in gastric adenocarcinoma (χ2 =6.362,P=0.012).Conclusion The expression of β-catenin will be a great help to judge the biological behaviors such as the malignant degree of tumor and the capacity of tumor invasion and metas-tasis.
ABSTRACT
Objective To explore the relationship between TGF-beta1,BRCA2,HER2,ER,PR and clinical factors in breast cancer.Methods The expression of TGF-beta1,BRCA2,HEB2,ER,PB in 67 cases breast carcinoma were detected by immunohistochemistry staining SP method.The correlation of the results with other parameters which included age,pathohistological grade,status of auxiliary lymph nodes were analyzed by mono-factor unconditional logistic regression analysis.Results The expression of TGF-beta1 was correlated with BRCA2.and the expression of BRCA2 was correlated with TGF-beta1 and c-erbB-2 in breast cancer.Condusion Overexpression of BRCA2 was related with TGF-beta1 and HER2 in breast carcinoma.It was useful in breast carcinoma prognosis by detecting these three factors.
ABSTRACT
The excellent results of 200 cases of chronic hepatitis B (CAH 167,CPH 16.CAH with liver cirrhosis tendency 11 and hepatitis-cirrhosis 6) treated with specific transfer factor extracted from HBVM positive placenta (PSTF) for 3 months in average.The clinical recovery rate was 83.0%,improvement 11.0%.unrecovery only 6.0%,and seroconversion of HBsAg and HBeAg was 9.9% and 32.9% respectively in the near-future.No sider-effect was found during treatment.The relapse rate was 13.9% during average 5.5 months follow-up after discharged,and the clinical recovery rate of the improved and unrecovered cases while they discharged from the hospital was 40.0% and 50.0% respectively during follow-up Therefore,the authors think that the PSTF perhaps an exellent agent similar to SSTF (specific transfer factor extracted from HBVM positive spleen) in treating chronic hepatitis B.But,owing to easiness to collect HBVM positive placenta in our country at present,PSTF perhaps could make a great offer for treating chronic hepatitis B,if it could be used correctly,and,therefore/it seems worthy for profound investigation.
