Objective To investigate the expression of KLF4 in cervical carcinoma and its significance. Methods Immunohistochemistry and tissue microarray were used to examine the expression of KLF4 in 39 cases of carcinoma, 30 cases of normal cervical epithelial tissues and 28 cases of cervical cancer in situ. Results Moderate to strong nuclear staining for KLF4 was found in normal tissues and cervical cancer in situ. Interestingly, KLF4 expression was lost in 16 (P<0.05) of 39 carcinoma cases. However, KLF4 expression was not associated with clinicopathologic parameters, including tumor stage and differentiation. Conclusion Our observations indicate that KLF4 may function as a tumor suppressor in the pathogenesis of cervical cancer.

Objective To establish a simple and practical superparamagnetic immunochromatographic test strip for rapidly monitoring human serum level of CA72-4. Methods Water-soluble carboxylated super-paramagnetic nanoparticles were prepared with a modified one-step hydrothermal synthesis method. Magnetic probe was prepared by immobilizing specific antibody (mAb1) onto the surface of nanoparticles. Following with optimization and assembly of the test strip , we evaluated sensitivity , specificity , stability of this method for serum CA72-4 detection. Results The optimized test strip provided not only the qualitative results, but also the high sensitivity quantitative detection through stable magnetic signal. The detection limit was 0.83 IU/mL. One hundred clinical samples ( 70 positive and 30 negative ) were measured to assess these test strips with high sensitivity (99%) and high specificity (93%). The test strip and magnetic signal possessed high stability. Conclusion A rapid and quantitative detection of CA72-4 by the test strip was accomplished. This method is rapid, sensitive and quantitative, possessing great potential in large sample screening or in-home testing.

Objective To explore the clinical characteristics and prognostic factors of breast carcinosarcoma.Methods Clinical data of 37 breast carcinosarcoma patients treated at Tianjin Cancer Hospital from 1974 to 2014 was analyzed retrospectively.Kaplan-Meier unvariate analysis was used to calculate the survival rate and compare the survival rates.Multivariate factors for survival were analyzed by COX proportional hazards regression model.Results 37 cases of breast carcinosarcoma were all female.The median age was 55 years.Among them 31 cases complained for painless mass,six cases had breast mass with skin ulceration.21 cases were three-negative breast cancer.Ten cases had axillary lymph node metastasis,ten cases had distant metastasis.The 5-year survival rate was 62.3％.Unvariate analysis showed that axillary lymphnodes metastasis (P =0.045) and therapeutic schedule (P =0.016) significantly influenced the oulcome of the patients.COX multivariate analysis validated that the therapy modality was an independent prognostic factor for breast carcinosarcoma(P =0.041).Conclusions Breast carcinosarcoma is rare and has a poor prognosis.ER,PR and HER-2 expressions in most cases are negative.If there is axillary lymph node metastasis,the prognosis is poor.A reasonable and comprehensive treatment can improve the prognosis.
