ObjectiveTo investigate the expression and significance of CDX2,Ki-67 in adenoma and colorectal adenocarcinoma,and the correlation between CDX2 and Ki-67.MethodsThe expression of CDX2 and Ki-67 was evaluated in the colorectal adenocarcinoma,adenoma and normal colorectal mucosa as control subjects by immunohistochemistry.ResultsThe magnitude of CDX2 were negatively correlated with the level of dysplasia in adenoma(rs=-0.38,P =0.02),and negatively correlated with differentiation,lymph node metastasis,diversion and Dukes stage of cancer in colorectal adenocarcinoma(rs=-0.49,rs=-0.37,rs =- 0.38,rs =-0.37,P =0.01).The expression and relativity of Ki-67 in the samples were contrary to the CDX2.The levels of CDX2 and Ki-67 expression had significant difference between the adenoma and adenocarcinoma,and showed negatively correlation in this two type tissues (rs=-0.69,P =0.00; rs =-0.40,P =0.00).ConclusionsCDX2 may be used as an effective marker to evaluate malignancy degree and prognosis of large bowel neoplasm patient.The levels of Ki-67 expression in colorectal adenocarcinoma are correlated with malignancy degree and clinical stage.The expression of CDX2 is negatively correlated with Ki-67.Combined detection of CDX2 and Ki-67 may be helpful for the judgment of colorectal tumor biological characters.

BACKGROUND: With wide application of biotechnological substitute materials, pelvic repair and reconstruction develop to a certain degree. Biomaterial patch is a major substitute for repairing injured pelvic fascia tissue, so it is widely used for pelvic reconstruction.OBJECTIVE: To investigate the feasibility, efficacy, and clinical value of biomaterial patch to pelvic reconstruction in the females.METHODS: Articles related to pelvic functional disorder, pelvic reconstruction, and application of patch implant were retrieved from PubMed (http://www.ncbi.nlm.nih.gov/PubMed) and (http://www.wanfangdata.com.cn) with the key words of "reconstruction of whole pelvic floor, mesh, synthetic mesh implants" in both Chinese and English between 1990 and 2008. Duplication studies were excluded. A total of 54 articles were initially retrieved, and 17 ones were included in the final analysis.RESULTS AND CONCLUSION:Pelvic organ prohpse, which was a major symptom of pelvic disorder in the females, caused by defect of pelvic supporting structure, injury, and functional disorder. Traditional operation could not solve fundamental question.At present, substitute materials for pelvic repair and reconstruction mainly include biomaterial patch (self-substitute materials, homogeneity substitute materials, and heterogeneity substitute materials) and artificial patch. All of them could substitute the injured pelvic fascia tissue; therefore, they were major substitute materials of pelvic tissue and widely used for pelvic reconstruction. Patch which was used for pelvic reconstruction realized the recovery of anatomic structure and caused functional recovery, with simple and easy processing. Additionally, patch application did not prolong operative time and cause complication, but induced well tolerance, security and reliability, and remarkable short-term effect on patients. However, the long-term efficacy should be further studied. The modified pelvic reconstruction is clinically valuable for patients with varying prolapsed sites.

BACKGROUND:The essence of cell differentiation is a selectively intra-cellular gene expression,which results in specific proteinic synthesis and causes changes in biochemistry,structure and function.Thus,original proteomics and a single protein analysis can not meet the requirement in study.Proteomics technology provides a powerful tool due to the large scale,systemical study of protein transformation and interaction,which can be used for exploring molecular mechanism of bone mesenchymal stem cells(BMSCs)during directional differentiation.OBJECTIVE:To introduce proteomics,to summarize the research of proteomics in directional differentiation of BMSCs,and to forecast the development of proteomics research methods.METHODS:To search articles highly related with BMSCs,cell differentiation,and proteomics published on CNKI (www.cnki.net/index.htm),Sciencedirect(http://www.Sciencedirect.com),I.S.I(http://www.isiwebofknowledge.com)were searched,and the key achievements were included in the analysis.RESULTS AND CONCLUSION:A total of 29 documents were reviewed,and the experiences in the application of proteomics technology in the directional differentiation of BMSCs were summarized.With the innovation and development in methodology and technology,proteomics will become a powerful tool for us to study the potential mechanisms of BMSCs directional differentiation.
