In this study, the expression of IL-24 at maternal-fetal interface and the roles in extravillous trophoblast (the TEV-1 cell line) invasion were examined. Immunohistochemistry was used to detect the expression of IL-24 in villi and decidual tissue. The proliferation of TEV-1 cells under the effect of IL-24 was measured by MTT assay. The invasiveness of TEV-1 cells under the effect of recombinant IL-24 (rhIL-24) was examined by transwell system. Immunohistochemical detection showed that IL-24 was expressed in the villi and decidual tissue, and distributed in villous column, trophoblasts, stroma and blood vessels. The proliferation of TEV-1 cells was not inhibited by rhIL-24 of various concentrations. The examination of invasion in vitro showed that rhIL-24 could inhibit the invasion of TEV-1 cells in a concentration-dependent manner. The results suggested IL-24 could inhibit the invasion of TEV-1 cells. Therefore, IL-24 produced by maternal-fetal interface in human first trimester pregnancy may influence the invasion of trophoblasts and is involved in normal pregnancy.

Objective:To investigate the hepatitis C virus (HCV) infection in hemodialysis patients.Methods:One hundred and fifty hemodialysis patients were tested for HCV-RNA using a reverse transcription-polymerase chain reaction (RT-PCR) assay and for anti-HCV IgG using an enzyme-linked mmunosorbent assay (ELISA).Result:The positive rate of anti-HCV IgG was 24%.The positive rate of HCV-RNA was 26.7%;the total positive rate of HCV markers was 35.3%.Conclusion:HCV infection rate in hemodialysis patients is higher than that of general population.The first-class risk factors for HCV infection is transfusion of blood,while the cross using of dialyzer and dialysis pipe-line is also one of the risk factors.

Objective To discuss the value of mammotome biopsy of breast cakified lesions under the real time guidance of mammography.Methods The data of 42 patients with 44 mammary gland calcification(2 patients with bilateral lesions)who underwent mammotome biopsy under the real time guidance of a mammography from Jan.2011 to Feb.2012 in the First Affiliated Hospital of Chongqing Medical University were retrospective analyzed.Rapid paraffin pathology was conducted.Results Among the 44 lesions,34 were benign(27 hyperplasia,2 fibroadenoma,1 lipoma,1 cyst,3 others)and 10 were breast cancer(a benign lesion diagnosed as breast cancer by postoperative biopsy was included).Among the 42 patients,32 patients had benign lesions,accounting for 76.2％ (32/42),10 patients had breast cancer,accounting for 23.8％ (10/42).All lesions were completely resected during the operation.Malignant lesions were given treatment such as modified radical mastectomy,breast conservation surgergery,chemotherapy and so on.A single lesion resection took about 20 minutes.During the follow-up of 3 months,no significant event happened.Conclusions Through the qualitative diagnosis of mammotome biopsy under the real time guidance of mammography,we can get early diagnosis of breast cancer.Early diagnosis and early treatment can improve the life quality and survival time.It is more important to detect early breast cancer which was considered benign lesions clinically.Mammotome biopsy under the real time guidance of mammography has several advantages including easy to operate,accurate positioning and less complications,making it the preferred approach in managing mammary gland calcification especially suspicious malignant calcification.

Objective To construct prokaryotic expression vector of NS5A transactivating protein 7 of hepatitis C virus (NS5ATP7), induce the expression of NS5ATP7 in E. coli, and to predict its structure and function by bioinformatics analysis. Methods NS5ATP7 gene was amplified by reverse transcription PCR (RT-PCR) using HepG2 cells mRNA as template, and was ligated into pGEM-T cloning vector. After verifying the sequence of the inserted fragment by restriction enzyme digestion identification and sequencing, NS5ATP7 was cloned into inducible prokaryotic expression vector pET-32a(+) and transfected into competent E. coli BL21. The protein expression was induced with IPTG and the product was analyzed by SDS-PAGE and Western blotting hybridization. The structure and function of NS5ATP7 were predicted using bioinformatics techniques. Results NS5ATP7 gene with about 891bp was amplified by RT-PCR, which was coincident with that we expected, and it was then inserted into expression vector pET-32a(+). Under the induction of IPTG, the recombinant NS5ATP7 was expressed successfully. SDS-PAGE and Western blotting assay showed that this recombinant protein possessed good immunogenicity. Bioinformatics method such as ExPASy, TMHMM and SignalP analysis indicated that NS5ATP7 was full of helices, had neither transmembranous structure nor signal peptide. Conclusions The recombinant NS5ATP7 gene could be successfully expressed in prokaryotic expression system of E. coli, which might lay the foundation of studying the immunogenicity and biological charactersitics of the NS5ATP7. Bioinformatics analysis may provide a new method to analyze the structure and function of a new protein.
