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 the effects of "total quantity control" indexes on community health services and the residents' use of them so as to provide scientific basis for furthering reform in the medical insurance system.Methods A survey was made on the operation of the 3 community health centers of Jiangbin Xincun,Huashanwan and Hejianong in Jingkou District of Zhenjiang by means of direct inquiry and literature review.Results The average annual quantity of medical insurance plans allocated to the centers in the last 4 years involved 810 thousand yuan,the quantity actually fulfilled involved(953.5) thousand yuan,and the estimated annual quantity the centers were capable of fulfilling was valued at(1.45) million yuan,nearly 500 thousand yuan more than the quantity actually fulfilled. Conclusion Total quantity control on community health centers not only hinders the healthy development of community health services and the enthusiasm of the medical workers but also adversely affects the residents'use of health services and their health maintenance.

Objective To investigate the role of insulin-like growth factor (IGF)-Ⅰ , ⅠⅠ , platelet-derived growth factors (PDGF)-AA,-BB and keratinocyte growth factor (KGF) in various stages of the pulmonary development in rats. Methods All lung tissues of fetal and neonatal rats were collected at the gestational age 18, 20, 21 d, and 1, 4, 7, 10 and 21 d after birth. The expression of IGF-Ⅰ , IGF- ⅠⅠ , PDGF-AA and PDGF-BB was detected by immunohistochemistry and Western blot, respectively. The levels of IGF- Ⅰ , IGF-ⅠⅠ , PDGF-A, PDGF-B and KGF mRNA were measured by reverse transcription polymerase chain reaction (RT-PCR). Results The peak expression of IGF-Ⅰ was at 4, 7 and 10 d after birth. IGF-ⅠⅠ was detectable early in fetal lung development and decreased gradually until 21 d after birth. The changes of IGF- Ⅰ , ⅠⅠ mRNA were similar to IGF- Ⅰ , ⅠⅠ polypeptides. The PDGF-A,PDGF-B mRNA were abundant early in fetal lung development. The steady state of PDGF-A chain mRNA was significantly different only at 7 d (0. 97?0. 23,P0. 05). The PDGF-AA polypeptide was abundant early in fetal lung development, and the expression peak was found in 1, 4 and 7 d after birth. KGF mRNA was higher in the fetal samples than that of rats after birth, but no difference in postnatal rats at all time points. Conclusions Peptide growth factors may play a critical role in the development of lung in rats.
