SUMMARY Left ventricular noncompaction(LVNC)is a rare congenital disorder of endomyocardial morphogenesis.Since the knowledge of aetiology and pathology is accumulating,the 2006 AHA cardiomyopathy classification sorts LVNC as one of the primary genetic cardiomyopathies.The clinical features of LVNC,however,is not as clear as its aetiology.We summarized the manifestation,hemodynamics,natural course,diagnosis,therapy and prognosis of LVNC by analyzing its clinical features of 2 cases and reviewing the latest related articles.

Objective To discuss the setting problem of control limit for quality control chart during the statistical quality con-trol procedure of clinical laboratory quantitative measurement.Methods The normality test of the monthly quality control data for 3 items of albumin (ALB),alanine aminotransferase (ALT)and creatinine (Cr)was performed by using the SPSS 14.0 statistical software and which was compared with the cumulated data.Results Among 30 groups of data,the normality test was inconformity in 18 groups,among 30 groups of mean t test,the differences in 20 groups showed statistical significance(P <0.05).Therefore,the calculated means and standard deviation(SD)in short term could not be directly set as the control limit of the quality control chart. Conclusion Setting the control limit of internal quality control in clinical laboratory quantitative measurement should be according to the guidance of C24-A3 document in CLSI.The SD estimated value obtained from large amount stable quality control data or the 6-month cumulative values is recommended to be used as SD of the new batch number,which should be regularly assessed.

Interdisciplinary can be acted in any stages of researching procedure.The interdisciplinary process research thinking were addressed including how to builds variables,which are depth and width,fixed discipline or not,and also to reflect the collaboration level of interdisciplinary in certain period.By this quantity evaluation mode building,it will useful for the interdisciplinary research in the future,especially in medical and life science fields.
