Objective To discuss the effect of negative pressure puncture without the cuff in staphylococal scalded skin syndrome (SSSS). Methods 68 children with SSSS in our department were chosen as research subjects from January 2009 to December 2010, and then were divided into the experimental group and the control group randomly. All children used the distal upper limbs for superficial vein puncture. The control group used vein puncture and catheter fixation by conventional methods, the experimental group used negative pressure puncture without the cuff in order to improve the methods for filling and indwelling intravenous needle fixation. Results In the experimental group, the parent satisfaction degree and the average catheter indwelling time were significantly better than the control group, the adverse reactions were lower than the control group. Success rate of one-time puncture and rate of venous blood return showed no significant difference compared with the control group. Conclusions The method of negative pressure puncture without the cuff is simple, easy to grasp and has a high puncture success rate, is better protection of skin and blood vessels for children with staphylococal scalded skin syndrome.

Objective To investigate whether non-critical coronary stenosis can be detected by coherent contrast imaging(CCI) at rest without stress.Methods Three degrees of stenosis were made in left anterior descending of 12 dogs.Myocardial contrast echocardiography(MCE) was performed with CCI and the correlation among the variables of MCE curve and the degrees of stenosis were analyzed by cubic regression.Results The time to peak was significantly prolonged with progressive coronary stenosis (P＜0.01) and related to the degree of stenosis (R~2=0.991,P＜0.001).Conclusions CCI could be used to detected non-critical coronary stenosis at rest without stress.

Objective To develop the clinical practice guidelines for the management of medication adherence to highly active antiretroviral therapy (HAART) in China. Methods The development methods included qualitative interview of 31 stakeholders, questionnaire survey of 423 PLHIV, adaptation of 30 clinical practice guidelines related to AIDS care, and overviews of reviews of 44 systematic reviews/Meta-analysis. Results 10 clinical practice guidelines and 10 systematic reviews/Meta-analysis were included. The clinical practice guidelines for the management of HAART were formed. Conclusions The formed clinical practice guidelines showed better applicability and higher general quality. It is recommended to use the guidelines in AIDS care.
