PTEN is a tumor suppressor with double specific phosphatase activity,and PTEN brings into its lipid and protein phosphatase activity through PIP3, FAK, MAPK pathway. PTEN also induces apoptosis, inhibits cell growth, and regulates cell migration and adhesiveness. PTEN expression is lower in gastric carcinoma. It may be valuable to evaluate that the abnormal expression of suppressor gene PTEN participates in the malignant conversion process of the gastric mucosa cell, and the expression levels of the PTEN protein can be used to evaluate the pathologic biology behavior of gastric carcinoma.

Endocardial myocardial biopsy is the gold standard in the diagnosis of viral myocarditis.However,the limitations of sampling to the low sensitivity,and invasive inspection methods limit its clinical application.The traditional diagnostic tool electrocardiography,laboratory values and echocardiography are lack of specificity.Thus,a non-invasive diagnostic approach with high sensitivity is in need.Cardiovascular magnetic resonance(CMR) can evaluate the function of the heart parameters,such as left ventricular function and regional wall motion,and various CMR imagings including T2-weighted imaging,and early- and late-contrast enhanced T1-weighted imaging can evaluate the hyperemia,oedema and necrosis of myocardial inflammation histological character.CMR provides a scientific basis for the diagnosis of viral myocarditis in clinical.

Enteral nutrition therapy is the first choice of clinical nutrition therapy method in children with disease.We should make full use of the gastrointestinal function and total nutritional therapy.The key is based on gastrointestinal function choose enteral nutrition infusion way,infusion pattern and prevention and treatment of refeeding syndrome.As following is introduction about a few problems.

OBJECTIVE:To provide legal basis for purchasing drugs by centralized bidding.METHODS:On the basis of the relevant laws,to expound the process of purchasing drugs by centralized bidding and the standards that should be observed. RESULTS ＆ CONCLUSION:Purchasing drugs by centralized bidding should observe the public bidding law of the People's Republic of China,only by observing the law can it benefits the nation and the people.

Urinary tract obstruction that occurs during early kidney development affects renal morphogenesis,maturation and growth,and in the most severe cases this will ultimately cause renal insufficiency.15％ ～ 20％ of the patients with obstructive nephropathy require early surgical intervention to preserve renal function,another part of those children without significant loss of renal function may be appropriate in conservative treatment because of spontaneous resolution.Current imaging examination for urethral obstruction are uncertainties and invasive,and therefore there is a need for urinary biomarkers that may be used as predictors for renal structural changes and decreasing renal function,and thereby provide the surgeon with more clear indications for surgical intervention.This review will discuss the clinical application value of various types of urinary biomarkers,including transforming growth factor-β1,monocyte chemoattractant protein-l,epidermal growth factor,endothelin-1,to provide important theoretical basis for searching new approaches for diagnosis,prevention and treatment of diseases related to ureteral obstruction and irreversible damage of kidney.

ObjectiveTo observe the turnover of impaired glucose tolerance(IGT)patients intervened with different measures.MethodsIGT 158 patients found by physical examination in the community residents were randomly divided into health education group,Chinese medicine group,and western medicine group,and treated with health education,traditional Chinese medicine and western medicine respectively.The fasting blood glucose,oral glucose after 2hour blood glucose (2hPG),serum lipid,glycosylated hemoglobin index were observed.ResultsThe efficiency of patients with IGT was 48.0％,70.3％ and 75.0％ in health education group,Chinese medicine and western medicine respectively.There was significant difference of therapeutic effect between the western medicine group and health education group (x2=7.96,P＜0.05),and between the traditional Chinese medicine group and health education group (x2=5.46,P＜0.05),while there was no significant difference between the traditional Chinese medicine group and Western medicine group (x2 =2.31,P＞0.05).ConclusionTraditional Chinese medicine and Western Medicine both have good effects on patients with IGT.But due to its good tolerability and few side effect,TCM may be more easily accepted by patients.

ObjectiveTo explore clinical effect of hemabate combined with uterine massage in treatment of postnatal hemorrhage caused by uterine inertia. Methods120 patients with postpartum hemorrhage caused by uterine inertia were selected and randomly divided into the experimental group(60 cases)and the control group(60 cases).The experimental group was given hemabate combined with uterine massage treatment,with respect to only hemabate treatment in the control group. ResultsThe total effective rate of postpartum hemorrhage were 96.7 and 92% with significant difference(x2 = 15.396,P＜0.01)between the two groups. Conclusionhe treatment of hemabate combined with uterine massage was more effective than hemabate alone.It was particularly safe,effective,convenient to operate,quickly to get results and of great value for clinical promotion.

Computer and Internet become a great threat to personal privacy. The paper introduces several forms of how computer and Internet threaten personal privacy, such as drive-by installation, webbug, electronic payment mechanism, as well as other computer or network application with potential privacy destruction, and provides some policies for protecting privacy, including improving legal system, applying websites privacy seal, etc.

Objective To assess the protective effect of Tangshentongbao decoction combined benazepril on renal function of the patients with diabetic nephropathy(DN) in clinical stage and to make a effective contrast to the therapy with western medicine. Methods 62 patients with DN in clinical stage were randomly divided into a control group and a treatment group, with 31 patients in each group. Both groups were supplied with the same food, adopted glucose control therapy and symptoms orientated treatment. On these basis, the treatment group was administered with Tangshentongbao decoction combined benazepril, and the control group was taken kallikrein enteric tablet combined benazepril. The therapeutic courses for both groups were 8 months. The changes of symptoms and physical signs, 24-hour urinay protein (24hUpro), serum cteatimine (SCr), serum creatinine clearance erate (CCr) , blood urea nitrogen (BUN), triglyceride (TG), cholesterd (CHO) and low density lipoprotein-cholesterol (LDL-C)of the two groups were separately assessed. Results 24hUpro, SCr, TG, CHO and LDL-C of treated group were all reduced after the treatment (P<0.01 or P <0.05), showing significant difference compared with the control group. Conclusion 24hUpro and SCr of patients with DN in clinical stage can be evidently reduced by Tangshentongbao decoction, and the effect of reducing blood lipid is remarkable better than western medicine alone.

CCL21 is originally reported as a CC chemokine mainly expressed in secondary lymphoid tissues. CCL21 can dictate lymphocytes homing in the flow environment,where T cells use integrins stimulated by CCL21 to arrest on endothelial cells,and can act as a chemoattractant for T cells,B cells,mature dentritic cells and natural killer cells strongly. CCL21 can collect activated effector cells and keep them around the tumor. It is also a pivotal molecule for priming T cell responses. Therefore,CCL21 plays a potential role in anti-tumor therapy, and its high expression is responsible for many immune diseases.
