ABSTRACT
Objective To investigate the expression of stratum corneum chymotuptic enzyme (SCCE) and its significance in human cervical adenocarcinoma.Methods Immunohistochemistry was used to detect the expressions of SCCE,ER,CEA and Vimentin in tissues from the group of 45 cervical adenocarcinoma patients,group of 24 cervical glandular intraepithelial neoplasia (CGIN) patients and group of 24 normal cervical tissues.Results The expression of SCCE was 84.44 ％ (38/45),58.33 ％ (14/24) and 8.33 ％ (2/24) in 3 groups respectively.The SCCE expression from group of cervical adenocarcinoma were more significantly than that of normal cervical tissues (P ＜ 0.012 5),the expression of SCCE from group of CGIN were more significantly than that of normal cervical tissues (P ＜ 0.012 5),but there was no difference between the cervical adenocarcinoma and the CGIN on the expression of SCCE (P ＞ 0.012 5).Conclusion SCCE could be recommended as a new biomarker for the early screening cervical adenocarcinoma and as an additional marker for the prognosis of cervical adenocarcinoma.
ABSTRACT
Objective To detect the expression of Survivin and hypoxia inducible factor-1α (HIF-1α) in prostatic hyperplasia and prostatic carcinoma,and investigate their roles and mutual correlations in pathogenesis and progression of prostatic carcinoma.Methods The expression of Survivin and HIF-1α in proliferative lesions of prostate (15 cases) and prostatic carcinoma (62 cases) were detected by immunohistochemistry method.The relationship between the expressions of Survivin and HIF-1α was analyzed,as well as their correlations with clinicopathological features.Results The positive expression of Survivin and HIF-1α were significantly higher in the prostatic carcinoma [71.0 ％ (44/62) and 69.4 ％ (43/62),respectively] compared with those of the prostatic proliferation [6.7 ％ (1/15) and 0] (x2 =20.56,P 0.001; x2 =23.56,P =0.001,respectively).The expression of Survivin and HIF-1α in prostate carcinoma was significantly related with the histological grading,clinical staging (x2 =10.64,5.39,7.62,6.43,all P ＜ 0.05).And there was positively correlated between Survivin and HIF-lα (rs =0.350,P =0.006).Conclusion Survivin and HIF-1α synergistically play important roles in pathogenesis and progression of prostatic carcinoma.
ABSTRACT
Objective To evaluate the association of c-erbB-2 protein expression with the prognosis of gastric carcinoma. Methods Eleven literatures were analyzed which published in recent 15 years on the relationship of c-erbB-2 with prognosis quantitively by software RevMan. Results The pooled odds ratio(OR) of 5-year survival rates was 0.69(95% CI:0.54～0.87)for all 11 literatures. The pooled odds ratio(OR) of three literatures from eleven literatures was 0.67(95%CI:0.48～0.94)which 5-year survival rates was determined as final index and OR as associated.For well-differentiated and advanced gastric carcinoma, the pooled odds ratio(OR) of 5～year survival rates were 0.18(95%CI:0.09～0.38)and 0.72(95%CI:0.47～1.09)respectively.Conclusion The association of c-erbB-2 expression with prognosis of gastric carcinoma is negative.
