T-cell acute lymphoblastic leukemia (T-ALL) is one of the most common types of leukemia in children. With over 50 ％ of activating Notch1mutations in T-ALL,identification of activating Notch1mutations has brought interest toward targeting the Notch signaling pathway in this disease.Small-molecule γ-secretase inhibitors (GSI) can block a critical proteolytic step required for Notch1activation,but the clinical application of GSI has been hindered. Therefore, new therapeutic strategies aim to design of effective antiNotch1therapies in T-ALL are needed, including combination therapies with molecularly targeted drugs and glucocorticoids. This review put emphasis on the molecular basis of Notch1, the mechanisms of action of oncogenic Notch1and clinical significance of Notch 1mutations in T-ALL.

Objective To investigate the efficiency of liver cancer with portal vein tumor thrombus (MPVTT),hepatic artery portal vein fistula (APVS) in patients with hepatic artery chemoembolization (TACE) combined with the clinical value of portal vein stent during treatment with APVS embolization.Methods From January 2012 to October 2014,59 cases of HCC patients who accepted the treatment of TACE + stent in portal vein embolization of + APVS surgery,companied with MPVTT and APVS were ret rospectively analyzed.The liver function,portal vein angiography and pressure at different time points were measured and compared before and after treatment,and follow-up and prognosis were recorded.Results After treatment with albumin,platelets (PLT) levels were higher than those before treatment (P ＜ 0.05),with PT values lower than before treatment (P ＜ 0.05).No statistical significance was found for aspartate aminotransferase (AST),alanine aminotransferase (ALT) before and after treatment (P ＞ 0.05).Stent implantation before and after stent implantation,the portal venous pressure of APVS embolization had signif icant difference (P ＜ 0.05).Portal venous pressure level of stent implantation was lower than before stent implantation (P ＜ 0.05).The portal venous pressure level of APVS embolization was lower than the stent implantation before and after stent implantation (P ＜ 0.05).At the 12 months after treatment,28 cases survived (47.46％);24 months after treatment,11 cases survived (18.64％) of the group;a total of 3 patients was lost to follow-up,the median survival time of the patients 24 months 16.5 months.Conclusions Liver cancer with MPVTT and APVS in the TACE combined with portal vein stent in the treatment process using APVS embolization can further improve the portal vein blood flow,and reduce the pressure of Dortal vein.

Stem cells offer considerable promise in the repair or replacement of damaged tissue in the body.Mature and functional endothelial cells play a pivotal role in neovascularization and maintenance of blood vessel integrity.Although being the best choice for transplantation endothelial,cells isolated from autologous vessels have been heavily obstacled in medical application due to poor resources and limitted proliferation potential in culture.Thus,stem cells have been the focus of the studies soareh for suitable cell sources.Several types of stem cells have been reported to possess endothelial cell differentiation potential.This article summarized the recent study on the sources,distribution,features-differentiation,animal experiments and clinical use of stem cells.Advantages and disadvantages are compared to provide a reference for the choice of evdothelial celia source.

The success of organ transplantation depends on the prevetion of acute rejection. T and B lymphocytes, the major components of the cellular and humoral immunization mediating the rejection response, respectively, have been extensively studied. The importance of matural killer(NK) cells in transplantation has become an increasing area of interest as reagents for their study have become available. Basing on this on the killer immunoglobulin-like receptor in the acute rejection response with kidney transplantation.

Objectives To understand the demand,payment capability and influencing factors of sanitary latrine construction in schistosomiasis epidemic areas in China. Methods In Hu’nan,Hubei,Anhui,Jiangxi,Yunnan,Sichuan and Jiangsu,2 counties in each province were selected and 3 villages with schistosomiasis prevalence in each county were randomly sampled. Thirty households were randomly sampled from each village for questionnaire survey. Results The major reasons for constructing sanitary latrine were cleanliness,sanitation and convenience in the rural areas;more than 98% of the households were willing to pay part of the construction,among them,the majority of the families hoped the payment kept within 100-500 yuan (RMB);the problem for the non-sanitary latrine users to construct sanitary ones by themselves was lack of money,technique and skilled labors etc;the residents with the knowledge of rural water supply and latrine improvement,eliminating,keeping livestock enclosure were willing to pay for the construction of sanitary latrine. Conclusion The families using non-sanitary latrine have strong will for constructing the sanitary ones,and they also have payment will and capability to some extents. Most families can afford to the latrine construction within 500 yuan (RMB);to strengthen health education and communication can promote the demand and payment will for construction of sanitary latrine among the people using non-sanitary latrine in schistosomiasis epidemic areas.

The fetal period is the critical time in the development of various organs.The changes in the intrauterine growth environment can cause fetal and neonatal multiple organ system underdevelopment and damage,which is also closely related to the adult diseases,including nervous system damage (such as brain development disorders,functional abnormalities and cerebral palsy,etc.),cardiovascular system damage(such as coronary heart disease,high blood pressure,etc.),growth disorders and metabolic disorders(such as insulin resistance,type Ⅱ diabetes,obesity,growth and development disorders),urinary system damage (such as interstitial renal disease,renal hypertension,etc.),respiratory system damage(such as respiratory distress syndrome,bronchial dysplasia,etc.),etc.In this paper,we introduced this to help clinicians to understand and strengthen the intervention measures to improve the quality of life.

[Summary] Colorectal cancer is the one of the most common malignancies in the world .Currently, surgery is the main treatment for colorectal cancer .Although laparoscopic surgery for colon cancer has been widely accepted , laparoscopic approach for rectal cancer is still in clinical trials .At present, several trails have shown that the short-and long-term outcomes of laparoscopic rectal cancer resection are similar with open surgery , but others have shown that pathological outcomes and total resection rates of laparoscopic surgery are unsatisfactory .Laparoscopic rectal cancer surgery needs more grade Ⅰ evidences .Nowadays , researchers are exploring new ways to treat rectal cancer .

Objective To provide basis for rational drug use of clinical practice by analysis of antidepressants application in Wuhan. Methods Antidepressants were classified according to the structure and mechanism. By using the analytical method of the defined daily dose (DDD) recommended by WHO,authors statistically analyzed the relative data of antidepressants used in 34 hospitals of Wuhan from 2011 to 2013. Results The consumption of the antidepressants had been increased year by year,selective serotonin reuptake inhibitor (SSRIs) and serotonin noradrenergic reuptake inhibitors (SNaRIs) were widely used and presented higher proportion than others in the consumption of antidepressants,the average amount of the sales was 50.49% and 21.81%,respectively.The application of tricyclic antidepressant (TCAs) decreased in Wuhan,the amount of sales for 3 years accounted for 0.56%,0.37% and 0.15%. Conclusion SSRIs and SNaRIs have already become the first-choice drugs in clinic practice because of good efficacy and high safety,other new types of antidepressants have a great potential for development,TCAs are fewly used now.

Roux-en-Y procedure has widely been used for digestive tract reconstruction after distal or total gastrectomy,and the Roux stasis syndrome is one of the most common complications.The symptoms of Roux stasis syndrome include abdominal pain,abdominal distention,nausea,vomiting and anorexia.Abdominal movement of the intestinal loop and reversed peristalsis cause delayed passage of gastric contents,which is the main cause of the Roux stasis syndrome.Prokinetic agents and electronic stimulation have been investigated as potential nonsurgical treatment methods for Roux stasis syndrome.Uncut Roux-en-Y anastomosis has been found to be effective in preventing Roux stasis syndrome.In the future,precise evaluation of the psychological changes of the digestive tract after the Roux-en-Y anastomosis and understanding the mechanism of Roux stasis syndrome would be more effective to help the surgeons to resolve the problems.
