ABSTRACT
Objective To investigate diagnostic value of GP73 in alcoholic disease .Methods GP73 was measured by ELISA in 44 alcoholic fatty liver ,43 alcoholic hepatitis ,32 alcoholic cirrhosis ,67 non‐alcoholic fatty liver patients and 120 healthy control per‐sons .Meanwhile ALT ,AST ,ALP ,GGT ,Alb ,TBil ,AFP were measured .Results GP73 of alcoholic fatty liver ,alcoholic hepatitis , alcoholic cirrhosis ,non‐alcoholic fatty liver patients and healthy control group were (84 .22 ± 26 .22) ,(157 .98 ± 39 .71) ,(201 .23 ± 61 .14) ,(62 ± 14 .02) ,(47 .08 ± 22 .75)ng/mL respectively .The GP73 differences between patients and healthy control group had statistical significance(P<0 .05) .Before and after therapy of alcoholic hepatitis and alcoholic cirrhosis patients had statistical signif‐icance(P<0 .05) .Sensitivity of diagnostic value of GP73 in ALD was 71 .4% and specification was 95 .2% .Conclusion Serum GP73 elevates in types of alcoholic liver disease and show significant diagnostic value .Decrease of GP73 could be applied to assess treatment of alcoholic hepatitis and alcoholic cirrhosis .
ABSTRACT
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.
