Objective To detection analysis of blood infectious disease markers in patients before blood transfusion or before surgery .Methods HBsAg ,anti-HBs ,HBeAg ,anti-HBe ,anti-HBc ,anti-HCV ,anti-HIV ,TP-Ab were detected for 3 542 cases of se-rum using chemiluminescence immunoassay(CLIA) and ELISA .Results For HBsAg ,there were 704 cases of positive among 3 542 cases ,the proportion was 19 .8% ;For anti-HCV ,there were 52 cases of positive among 3 032 cases ,the proportion was 1 .72% ;For anti-HIV ,there were 3 cases of positive among 3 049 cases ,the proportion was 0 .09% ;For TP-Ab ,there were 200 cases of positive among 3 153 cases ,the proportion was 6 .34% .The infection rate was different in different gender of HBV ,anti HCV ,anti HIV and TP-Ab .But for HBV ,anti-HCV and TP-Ab ,the detection rate of male was higher than female(P<0 .05);The infection rate was different in different age of HBV ,anti HCV ,anti HIV and TP-Ab different age .The detection rate of HBV and Anti-HCV in 21-40 years old was the highest ,They were 31 .9% and 2 .33% ;The detection rate of TP-Ab increases with age increased ,more than 60 years old was the highest ,up to 7 .55% .Detection of the above two methods ,for HBsAg ,there were 51 cases did not match ,the proportion was 1 .44% ;for anti-HCV ,there were 1 case did not match ,the proportion was 0 .03% ;for Tp-Ab ,there were 3 cases did not match ,the proportion was 0 .1% ;for anti-HIV ,CLIA agrees well with ELISA ,there were 3 cases of positive .The samples that did not match were detected by the third party verification of the reagent .The result displayed that CLIA was more accurate . Conclusion CLIA is a high-sensitivity detection method which could effectively avoid positive specimens missed ,detection of infec-tious disease markers in patients before transfusion or before surgery by CLIA had important significance .

Objective To study the effect of massive blood transfusion program(MTP) in early massive blood transfusion and preventing coagulopathy.Methods Fifty cases of massive blood transfusion were clinically collected and performed the statistical analysis and processing before and after intervention according to the blood transfusion scheme of MTP.The statistical comparison was performed by using the data before and after intervention.Results PLT was decreased with the increase of transfusing of RBC.After transfusing 15 U of RBC,the PT test,INR and APTT were increased significant(P＜0.05).After transfusing 20 U of RBC,the Fib was decreased significant(P＜0.05).The MTP had statistical difference between before and after intervention(P＜0.01).Conclusion The MTP application has an important significance to prevent the occurrence of coagulopathy and evaluate the coagulation status.

The methylation status of GNAS1 gene in pseudohypoparathyroidism type Ib patients was detected by methylation-specific PGR technique. There was an abnormal methylation of 1A region in all seven PHPIb patients. Loss of exon 1A methylation (imprinting defect) seems to be the cause of PHPIb.

Objective: To explore the correlation between lipoprotein-associated phospholipase A2 (Lp-PLA2) level and albuminuria in patients with type 2 diabetes mellitus (T2DM) ． Methods : 200 T2DM patients were chosen to collect general data and relevant laboratory indicators． According to the urinary albumin / creatinine ratio ( UACR) ，they were divided into normal group (UACR＜30 mg / g，n = 66) ，microalbuminuria group (30 mg / g≤ UACR＜300 mg / g，n = 64) and macroalbuminuria group (UACR≥300 mg / g，n = 70) ．On the basis of Lp-PLA2 tertile，they were divided into low Lp-PLA2 group (Lp-PLA2 ＜104 ng / ml，n = 66) ，medium Lp-PLA2 group ( 104 ng / ml≤Lp-PLA2 ＜161 ng / ml，n = 67) and high Lp-PLA2 group (Lp-PLA2 ≥161 ng / ml，n = 67) ．Group differences were compared by analysis of variance and nonparametric test．Associations between Lp-PLA2 and other indicators were performed by Pearson correlation and Spearman correlation. Related factors of albuminuria in T2DM patients were explored by multivariate Logistic regression analysis． In addition ，receiver operating characteristic (ROC) curve analysis was applied to evaluate the predictive value of Lp-PLA2 for albuminuria in T2DM patients. Results: Lp-PLA2 was significantly higher in the macroalbuminuria group than that in both the normal group and the microalbuminuria group，and the differences were statistically significant (P＜0. 05) ．Compared with the normal group，Lp-PLA2 in the microalbuminuria group increased(P＜0. 05) ．With the increase in Lp-PLA2 tertile， there was gradual increase in UACR , and the difference was statistically significant (P＜0. 05) ．Correlation analysis showed that Lp-PLA2 was positively correlated with duration of DM，systolic blood pressure (SBP) ，glycosylated hemoglobin (HbA1c) ，fasting blood glucose (FBG) ，blood urea nitrogen (BUN) ，serum creatinine (Scr) ，UACR and negatively correlated with estimated glomerular filtration rate ( eGFR) (P ＜0. 05 ) ． Multivariate Logistic regression analysis showed that Lp-PLA2 ［OR = 1. 046，95% CI( 1. 031，1. 060) ］was an independent risk factor for albuminuria (P＜0. 05) ．The AUC of Lp-PLA2 for predicting albuminuria was 0. 902 ［95% CI(0. 862，0. 942) ］. The cut-off value of Lp-PLA2was 148 ng / ml，the sensitivity was 65. 7% and specificity was 98. 5%． Conclusion Lp-PLA2 is closely related to the albuminuria in T2DM patients，which provides a new method for the diagnosis and treatment of diabetic kidney disease (DKD) .
