1.Progress on Notch signaling in T-cell acute lymphoblastic leukemia
Journal of Leukemia & Lymphoma 2012;21(7):441-444
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.

Chinese Journal of Minimally Invasive Surgery 2016;16(7):650-655
[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 .
4.Analysis of Antidepressants Consumption in 34 Hospitals of Wuhan During 2011-2013
Herald of Medicine 2015;(9):1230-1233
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.
5.Updates in the research of Roux stasis syndrome
Chinese Journal of Digestive Surgery 2015;14(7):593-597
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.
6.Progress on the killer immunoglobulin-like receptor in the acute rejection response with kidney transplantation
International Journal of Surgery 2009;36(2):103-106
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.
7.Analysis of the Causes and Measures to Medical Students'Plateau Phenomenon in English Study
Chinese Journal of Medical Education Research 2003;0(04):-
The causes of "Plateau Phenomenon"in College English learning are analyzed on the basis of the investigation and the study of the Learning Curve.Some solutions to cope with the stagnation are also suggested.It's worth attention that Learning Strategy can be a vital factor to overcome the"Plateau Phenomenon."
8.Enriching the contents of the courseware with visualized data to elevate the teaching quality of ‘General’of pediatric surgery
Chinese Journal of Medical Education Research 2006;0(10):-
A visualized reformation was carried out in the multimedia coursewares through collecting and adding the related pictures and professional video information.Through the teach-ing practice in the last three years,we have got the opinion from the students that by overcom-ing the stiffness and dullness of the old"General",the reformed"General"obviously has sur-passed the old"General"in teaching quality.
9.Study on multiple stem cell sources for mature vascular endothelial cells
International Journal of Biomedical Engineering 2008;31(4):201-205
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.
10.Analysis of the difference on the effect of atropine sulphate and cyclopentolate hydrochloride in the treatment of youth hyperopia cycloplegic refraction
Chinese Journal of Postgraduates of Medicine 2012;(33):15-17
Objective To compare the effect of atropine sulphate and cyclopentolate hydrochloride in the treatment of youth hyperopia cycloplegic refraction,and provide the basis for a reasonable choice of the youth cycloplegic refraction drugs.Methods Ninety hyperopia children met inclusion criteria with refractive errors (180 eyes) were subjected to cycloplegic refratometry by 1% cyclopentolate hydrochloride followed with 1% atropine sulphate eye used gel.The refractive results,pupil size,residual adjustment amount and systemic side reactions were measured and compared by TOPCON.Results The coincidence rate of spherical lens degrees,cylinder lens degrees and axis of astigmatism degrees respectively was 84.44% (152/180),92.78% (167/180) and 92.78% (167/180) between atropine sulphate and cyclopentolate hydrochloride.The spherical lens degrees of cyclopentolate hydrochloride was lower than atropine sulphate,the difference was statistically significant (P <0.01),the cylinder lens degrees and axis of astigmatism degrees had no significant difference between two drugs (P> 0.05).The pupil size and residual adjustment amount of cyclopentolate hydrochloride had no significant difference with atropine sulphate (P > 0.05).The incidence of adverse reactions of cyclopentolate hydrochloride was 3.33% (3/90),atropine sulphate was 13.33% (12/90),the cyclopentolate hydrochloride was significantly lower than atropine sulphate (P < 0.05).Conclusion The cyclopentolate hydrochloride has powerful,fast and secure feature in the treatment of youth hyperopia cycloplegic refraction,has good ciliary muscle paralysis effect,has longer paralysis time,as effective as the atropine sulphate,and has a shorter recovery time and better security,is ideal cycloplegic drugs for youth hyperopia cycloplegic refraction.
