Community health service is an effective measure to relieve the difficult medical services and expensive medical cost problem,but community inhabitants in Chongqing make little use of community health service.The actual cause is that people s degree of trust in community health service is low.In view of existing situation,this article analyzes the various factors that influence community residents' degree of trust in community health service and puts forward corresponding policy proposal.

Tumor markers for early diagnosis of cancer is an important auxiliary mean,which for early tumor detection,monitoring and for judging curative effect of treatment regimens play important role.Clinical method for early diagnosis on ovarian cancer is the detection of serum CA125,however,its precision and specificity for early diagnosis are not enough.It has been found that in the development period of the patients with ovarian cancer,SMRP and CA125 is co-expression.This article reviews the value of serum mesothelin on diagnosis of epithelial ovarian cancer to provide reference on early diagnosis and treatment.

NOK is a newly identified receptor protein-tyrosine kinase (PRTK) molecule that can promote tumorigenesis and metastasis. Previous data showed that NOK could activate the phosphatidylinositol 3'-kinase (PI3K) pathway in stable BaF3 cells. But how does NOK activate PI3K in cells remains unknown. It was showed that NOK physically interacted with the PI3K downstream effector Akt and enhanced its activation in human embryo kidney 293T (HEK293T) cells. Deletion mapping indicated that protein kinase B (Akt) was able to directly contact with the kinase domain of NOK. Inactivating the Akt kinase domain significantly reduced the intermolecular interaction between NOK and Akt, while constitutively active mutant of Akt apparently had a stronger interaction with NOK. NOK did not have an additive effect on insulin-mediated Akt activation. Overall, the results indicate that NOK might complex with Akt and directly activate PI3K/Akt signaling pathway.

Objective To study the diagnostic value of spiral CT pulmonary angiography(SCTPA) for pulmonary embolism(PE).Methods SCTPA scans were performed in 25 patients with PE,the contrast-enhanced SCT scans of the pulmonary arteries were performed,MPR,MIP and SSD were performed simultaneously.Results The 29 SCTPA scans were performed in 25 patients, including the central type in 23 cases(92%) and the peripheral type in 2 cases(8%).The rates of the main,the sinistral and dextral,the middle lobular,the lobular and the lingular pulmonary artery displayed were 100%,the rates of the segmental pulmonary artery displayed were 97.77% and the rates of the subsegmental pulmonary artery displayed were 68.00%.The lobular and segmental pulmonary artery were mainly embolized,the rates of PE were between 46.58% and 75.00%.Conclusion SCTPA has great value in earlier and clear and definite diagnosis of PE.

Objective To study the effect of PPARγ ligand troglitazone (TGZ) on invasion and metastasis of gastric cancer cells, and investigate the relationship of PPARγ ligand with gastric cancer.Methods The expression of PPARγ in gastric cancer cell line MGC803 were detected by immunofluorescence cytochemistry method. The effect of different density TGZ on proliferation activity and adhesion of gastric cancer cell were detected by MTT chromatometry. The effect of different ligands on invasion and metastasis of gastric cancer cell MGC803 were detected by invasion system in vitro. Results The expression of PPARγ mainly located in cell nucleus. TGZ inhibited the proliferation of gastric cancer cell, decreased cell adhesion, locomotory capacity and invasion to matrigel, which had time and dose-dependent relationship.When treatment with 0. 1,1.0 and 10μ mol/ L TGZ, inhibition ratio of invasion and metastasis of cell was 8.79% ,31.31% ,51.42% and 28.29% ,4. 27% ,59. 27% respectively, which had statistical significance compared with control group( P <0. 05). When treatment was 10μ mol/L TGZ, cell adhesion was 0. 32 ±0. 03, it was statistically significant higher than that in control group (0. 52 ± 0. 04, P < 0. 05 ). Conclusion Human gastric cancer cell line MGC803 expressed functional PPARγ protein. TGZ inhibited adhesion and invasion of MGC803 cell on ECM at different degree, the effect of combination of two ligands was evident, which mechanism of action needed to be further investigated.

Objective To understand status quo of the domestic and foreign iceberg competency model application,and to provide basis for further study in the nursing iceberg competency model.Methods A literature review about the application of competency iceberg model at home and abroad since 2009 was carried out,the relevant data was listed,and the research situation of domestic and foreign nursing iceberg competency model was summarized.Results According to the 141 total literatures whose theme was the iceberg competency model,only 3 articles were related to the nursing field,while most of the iceberg competency model aimed at the study of enterprises in the high-level management personnel,sales personnel and so on.More researches on competency iceberg model were conducted abroad,involved in all walks of life,an research direction of nursing had turned from general iceberg competency model to the study of specific posts.Conclusions The iceberg competency model applied to the management of nursing human resources in China is developed lately and the studies lack breadth,depth and scientificalness.Compared with foreign countries,there is a big gap.A thorough iceberg competency model for human resource management is ought to be studied to provide a new perspective and a more useful tool for the early Chinese nursing theory and practice.

In the experiments we used T_6 medium prepared by ourselves and mixed with diferent concentrations of human serum albumin or mother's serum, from which we prepared follicular flushing medium, insemination medium and growth medium. Clomiphene citrate and HCG were used for inducing superovulation. The semen was obtained through masturbation and artificially capacitated. A mature ovum and 2-3 drops of capacitated semen were incubated together in insemination medium in the culture box containing 5% CO_2 in air atmosphere at 37℃. The ovum was aspirated and transferred into the growth medium and incubated for 16-17 hours. By this time the ovum was already fertilized with the appearance of 2 pronuclei. About 30 hrs, it normally developed into two-cell stage, 40-44 hrs, it cleavaged into 4-cell stage. After 72 hrs, the fertilized ovum grew into morula. Up to June, 1986 twentythree ova in vitro fertilized and cultured were transfered into 14 mothers, uteri at the four-cell stage. The details of fertilization and the early embryo development in vitro were described.

Objective:To explore the expression of GITR/GITRL in rheumatoid arthritis(RA)and its correlation with clinical features of the disease.Methods:Fifty three RA patients,35 osteoarthritis(OA)patients and 35 healthy volunteers were included in the study.The real-time-fluorescence quantitative PCR method was used to analyze the expression level of GITR/GITRL mRNA.Using fluorescence-activated cell sorting(FACS),the expression of GITR on CD4+CD25+ T cells in peripheral blood monouuclear cells(PBMC)was detected.The levels of Anti-CCP antibody,C-reactive protein(CRP),erythrocyte sedimentation rate(ESR)and rheumatoid factor(RF)of the RA patients were measured at the same time.Results:It was shown that the level of GITR/GITRL mRNA and the percentage of GITR+ T cells in the CD4+CD25+ T cell subpopulation[12.38?5.72/16.41?10.16,(28.12?16.85)%] were significantly higher than those of the OA group [9.59?5.87/12.09?7.53,(21.01?14.42)%,P
