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.

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.

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.

Component separation technique in recent years both at home and abroad is mainly used in the repair of abdominal wall defects and abdominal wall reconstruction,especially for the great defect of the abdominal wall repair.Combined with laparoscopic minimadly invasive techniques,synthetic patch reflects the technology advantage in the abdominal wall reconstruction.This paper focuses on the surgical principle of component separation technique,indications,advantages,methods of operation,complications and related progress

Nuclear factor-E2 related factor 2 (Nrf2)can protect the normal cells from the damage of oxidants and electrophones,preventing tumorigenesis and metastasis.However,the abnormal activation of Nrf2 in tumor cells can lead to tumor development.Chemicals acting on Nrf2 pathway include activators and inhibi-tors,Nrf2 inhibitors can increase the chemosensitivity of the tumor,providing a new idea for the drug design of high-efficiency and low-toxicity.

Objective The difference of the equivalent IOL powers before and after LASIK was calculated by using the Haigis-L formula and Sirius ray-tracing respectively.And study the correlation be-tween the intraocular lens power and the myopic before laser in situ keratomileusis.Methods Ninety-one patients undergoing myopic laser in situ keratomileusis were enrolled, they were divided into 3 groups ac-cording to myopic diopter, group I (-1.00D~-3.00D) 13cases, group II( -3.25D and -6.00D)60 cases, group III(-6.25D~-10.0D)18 cases.The equivalent IOL power before and after LASIK will be calculated using Haigis-L formula and Sirius ray-tracing.The data were analyzed using SPSS20.0.Results 80.2%of the cases calculated using Haigis-L formula were within ±0.50D of the predicted refraction , 94.5%were within ±1.00D, and 100%within ±1.50D.also, within ±0.50D of the predicted refrac-tion 13cases(100%),51cases(85%),9cases(50%) in group I, II, III respectively.74.7% of the eyes calculated using Sirius ray-tracing were within ±0.50D of the predicted refraction , 89.0%were within ± 1.00D, and 100%within ±1.50D.within ±0.50D of the predicted refraction 12cases(92.3%),48cases (80%),8cases(44.4%) in group I, II, III respectively.Conclusions Sirius ray-tracing and Haigis-L formula can calculate IOL power accurately in eyes with prior myopic LASIK, with no need for preoperative data.and there is positive correlation between the intraocular lens power aberration and the myopic diopter before LASIK.

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.
