This article discusses the ethical problem about functional appliance in orthodotic treatment. The problem mainly includes:(1)aacuate diagnosis cant be obtained and exhaustive plan for treatment cant be established. (2)It is lacked to devote your cause, so that making appliance is not normative and meticulous.(3)moral responsibility is not strong when doctors are inquired.The author brings forward some suggestions:(1) it is so hard to study professioinal knowledge,and improving level of treatment and culture.(2)moral responsibility must be strong enough when facing with patients.(3)doctors should attach importance to young patients so as to build a good relation of doctors and patients.

Due to the complicated and changeable clinical symptoms,and inexact pathogenesis,leukemia was facing huge challenges in diagnosis and therapy.Aptamer could be selected through CELL-SELEX.The aptamer not only display high affinity and specificity to target cell,but also it could discriminate the specific stage of cell,such as different classification,normal and tumor cells.So CELL-SELEX has great potention in the researches of leukemia.This paper systematically summarized the advantages of CELL-SELEX,the application in specific leukemia diagnosis,targeted therapy and the discovery of cancer biomarkers.(Chin J Lab Med,2013,36:377-379)

Objectives:To observe the therapeutic effect of Cuochuang Misture on acne vulgaris and study the mechanism by external bacteria repressing experiment.Methods:34 cases of acne of syndrome of dampness and heat in lung and stomach were treated with Cuochuang Misture and 28 cases with Dangguikushen Pill as controls,and their curative effect were compared;Different concentration of Cuochuang Misture were used to inhibit Propionibacterium acnes(P.ance)and Malassezia furfur(M.furfur).Results:The clinical total effective rates were 94.12%in the treatment group,and 89.29%in the control group.The scores of skin lesions and syndromes reduced obviously between two groups in the end of the treatment(P

Objective: To explore the relationship between strain rate parameter and left ventricular diastolic function (LVDF) in patients with cardiac resynchronization therapy (CRT) by two-dimensional speckle tracking echocardiography (2D-STE).
Methods: A total of 70 heart failure (HF) patients with CRT were studied. The early left ventricular diastolic strain rate was obtained by 2D-STE technology, the differences of left ventricular diastolic functional parameters to various CRT echocardiographic responses were observed. The area of relevant parameters under ROC curve was calculated by early left ventricular diastolic strain rate for predicting CRT echocardiographic response.
Results: There were 41 patients presented as CRT echocardiographic responders at 12 months of follow-up period, 29 patients were non-responders. The most parameters of LVDF were signiifcantly improved than the base line in 41 responders. The maximum area of 2D-STE derived parameters under ROC curve was obtained by LSRE predicted CRT echocardiographic response
Conclusion: LSRE had greater value for predicting CRT echocardiographic response, it might be used as a sensitive index for evaluating LVDF in HF patients.

Objective To investigate the cytogenetic toxic effects of copper sulfate on root tip cells of Zea mays L.Methods The root tip cells of Zea mays L were treated by copper sulfate as mutagen at the doses of 0.05,0.10,0.25,0.50,1.00 g /L for 24 hours.The mitotic index,the micronucleus rate and the chromosome aberration rate of tip cells of Zea mays L were measured.Results Compared with the negative control group,the micronucleus rates and the mitotic index in 0.05,0.10,0.25,0.50,1.00 g /L groups and the chromosome aberration rates in 0.05,0.10,0.25,0.50 g /L groups increased significantly(P
