Multiagent chemotherapy has significantly improved survival for childhood ALL.However,the relapse rate with current therapies remains at 20% to 30%.Numerous studies have proved that the minimal residual disease(MRD)is associated with relapse rate.The major methods for the detection of MRD include polymerase chain reaction(PCR)and flow cytometry(FCM).The measurement of MRD in childhood acute lymphoblastic leukemia offers the promise of individualized,risk-stratified treatment and the prediction for post-transplant outcome.

Construction of security system plays an important role in the management of archive in research institute.With years' practice and exploration,we summarize our experiences in building up the security system of our institute here.This article involves two aspects of archive work,one is the conscious awareness of archive security and security system building.Suggestion on security cultural construction,digital file safety and data backup are also given.

Case based study emphasizes on the training of students' practical clinical ability. With the development of computer technology, picture archiving and communication system was widely applied, providing bases for case based study. According to the characteristics of radiology, appli-cation of case based study in medical imaging practice teaching was believed to stimulate students' learning interest, improve their analytical ability and thinking capacity, make them combine theory with practice better and develop their clinical thinking ability.

Objective To investigate the effects of fruit potassium supplement on hypokalemia at in the perioperative period of percutanous coronary intervention(PCI)? Methods Ninety cronary herat disease patients with hypokalemia undergoing PCI during July to December 2011 involved the study? Since admission,the patients were administered with oranges and bananas each 500 g daily until the third day after PCI,on the basis of oral administration of potassium? Serum potassium was assessed in all patients at time points of the day at PCI,the first day and third day after PCI? Results The time range for the patients to take potassium supplement by eating fruits was 12-45 hours,averaged(28?84 ± 11?70)hours? The serum potassium levels on days 1 and 3 were significantly higher than that on the day for the admission(P < 0?05 for both)and even maintained at the normal level? Conclusion The oral complement of potassium by eating bananas and oranges can help patients to correct and prevent hypokalemia during the perioperative period of PCI?

In order to safeguard the legitimate rights and interests of the subjects and the interests of the whole society , a relaxed and harmonious environment was created to ensure the normal medical research , clini-cal research trials which fit in trial of ethical review. The protocol assessment form and ICF assessment form to review are two cornerstones of protecting subjects. A good ICF assessment form is a necessary means to help improve the quality of the Ethics Committee for review .

Biomedical research involving human subjects must be approved by the ethical review. The method of improving ethics committee members of the examination quality is not only by the members themselves , but also a good plan of the work table, which is also a necessary means to improve the quality of the ethical review.

In order to better serve disease experimental research and reach forecasted combination of disease and symptoms,it sums up the establishment of hypertension model of hyperaction of liver Yang,and makes exploration and induction to its evaluation index.

OBJECTIVE:To establish the quality standard of Gongyanping dispersible tablets.METHODS:Melastoma dodecandrum,Zanthoxylum nitidum and Ficus simplicissima in the formulation was identified by TLC,and the content of gallic acid in gongyanping dispersible tablets was determined by HPLC.RESULTS:The TLC spots were clear,well-isolated and distinctive.The linear range of gallic acid was 0.146 48～2.929 6 ?g(r=0.999 7)and its average recovery was 99.89%(RSD=2.53%,n=6).CONCLUSION:The established quality standard can be used for the quality control of Gongyanping dispersible tablets.

Objective To observe the effects of interleukin-1 ?(IL-1?) on spontaneous electrical activity of neurons in paravenrticular nuclei,and discuss the possible mechanism.MethodsExtracellular recording technique was employed to observe the effects of IL-1? on spontaneous electrical activity of neurons in paravenricular nuclei in rat hypothalamic slices,and the influence of losartan on the electrical activity induced by IL-1? was examined.ResultsAfter exposure to IL-1?(1?10-7 mol/L),the discharge frequency was significantly increased in 46 of the 59 discharge units(78%) of neurons(P
