Objective This study aimed to investigate the expression of SOX7,β-catenin and cyclin D1 in invasive breast cancer and hyperplastic disease of the breast,and explore their relationship with clinical pathology charactersis in invasive breast cancer in order to provide valuable biomarkers for the treatment and prognosis.Methods The expression of SOX7,β-catenin and cyclin D1 was neasured in 50 invasive breast cancer tissues and 30 hyperplastic disease of the breast by immunohistochemical SP method.The correlations of SOX7,β-catenin and cyclin D1 in invasive breast cancer to clinicopathologic features were analyzed,such as age,size of tumor,axillary lymph node metastasis,histological grade,pTNM stage,ER,PR,Her-2 expression and the risk.Results Immunohistochemical results showed that the positive rates of SOX7 and cyclin D1 in invasive breast cancer were 42％ (21/50)and 70％ (35/50),and the abnormal expression rates of β-catenin in invasive breast cancer was 70％ (35/50).The positive rates of SOX7 in invasive breast cancer was significantly lower than that in hyperplastic disease of the breast 70％ (21/30).The expression of SOX7 had difference between two groups (P =0.021 ＜0.05).The abnormal expression rates of β-catenin and the positive rates of cyclin D1 in invasive breast cancer wcre significantly higher than that in hyperplastic disease of the breast 43.3％ (13/30) (P =0.033 ＜ 0.05) and 20％ (6/30) (P =0.000 ＜ 0.001).The expression of β-catenin and cyclin D1 had difference between two groups.In invasive breast cancer,SOX7 and β-catenin protein expression in 12 cases,while negative expression in 5 cases; SOX7 and cyclin D1 protein positive expression in H 1 cases,while negative expression in 5 cases; β-catenin and cyclin D1 protein positive expression iu 28 cases,while negative expression in 8 cases.Results of the analysis by Spearman showed that in invasive breast cancer the SOX7 protein expression was negatively correlated with the abnormal expression of β-catenin protein and the expression of cyclin D1 protein(r =-0.282,P =0.046 ＜ 0.05 ;r =-0.327,P =0.020 ＜ 0.05)while the abnormal expression of β-catenin protein was positively correlated with the expression of eyclin D1 protein(r =0.333,P =0.018 ＜ 0.05).In invasive breast cancer the expression of SOX7 protein was correlated with age,axillary lymph node metastasis,histological grade,pTNM stage,ER,PR,Her-2 expression and the risk(P ＜0.05),but with no correlation with size of tumor (P ＞ 0.05).However,the abnoral expression of β-catenin and the positive expression of cyclin D1 in invasive breast cancer were correlated with size of tumor,axillary lymph node metastasis and pTNM stage(P ＜ 0.05),but with no correlation with age,histological grade,ER,PR,Her-2 and the risk(P ＞0.05).Conclusions SOX7.β-catenin and cyclin D1 are frequently abnormality-regulated in invasive breast cancer tissues,and the three protein may play a regulatory role through the same pathway in the development and progression of invasive breast cancer.SOX7,β-catenin and cyclin D1,s abnormal expression in invasive breast cancer correlate with the clinical pathology charactersis,and the three protein may be valuable marker for assessing the prognosis for invasive breast cancer.

Study found that in some human tumors such as breast cancer,SOX7 gene is highly likely to be a tumor suppressor gene.The tumor suppressor role of SOX7 may be accomplished by regulating the Wnt/β-catenin signaling pathway mediated the transcription process,and the abnormal Wnt/β-catenin signaling pathway is likely to play its role through the regulation of its downstream target gene Cyclin D1,etc,so that the ahnormal cell proliferation activity is unable to carry on,and thus plays the function of tumor suppressor.This review will summarize the research progress of the role of SOX7 geue and its closely related β-catenin,Cyclin D1 gene in breast cancer.

Objective To explore the clinical effect of concurrent radiotherapy and chemotherapy in the treatment of advanced cervical cancer.Methods From January 2010 to January 2011,sixty patients with cervical cancer in Taizhou Cancer Hospital were randomly divided into two groups ,with 30 cases in each group.The control group was given radiotherapy alone ,the observation group was given concurrent radiotherapy and chemotherapy .The adverse reaction,curative effect,long -term effect of 5 -year follow -up were compared between the two groups. Results The total effective rate of the observation group was 93.33%,which was significantly higher than 73.33%of the control group,the difference was statistically significant (χ2＝14.397,P＜0.05).The 5-year survival rate of the observation group was 76.67%,which was significantly higher than 53.33% of the control group,the difference was statistically significant ( χ2＝11.922,P ＜0.05).The local recurrence rate and distant metastasis rate of the observation group were 16.67%,13.33%,respectively,which were significantly lower than those of the control group , the differences were statistically significant (χ2＝7.401,5.115,all P＜0.05).The incidence rate of adverse reaction of the control group was 13.33%,which of in the observation group was 23.33%,the difference was not statistically significant(χ2＝3.340,P ＞0.05).Conclusion The efficacy of concurrent radiotherapy and chemotherapy for patients with advanced cervical cancer is better ,and the survival rate of patients with advanced cervical cancer is better.
