0.1) except for a concentration reduction by more than 10% in 5% glucose injection in PVC infusion packages at 25℃.CONCLUSION:5% glucose injections in PVC infusion packages should not be used under high temperatures in the clinic.

Objective To discuss the diagnostic value of HIT-antibodies in suspected HIT patients with heart diseases.Methods A single center study.We collected 242 blood samples of suspected HIT patients whose platelet count decreased after heparin application during July 1 st ,2012 to June 30th ,2016 in Wuhan Asia Heart Hospital and detected the concentration of HIT antibodies , meanwhile the 4T′s score were calculated.Among the study objects , there are 206 patients received cardiac surgery , 28 received cardiac interventional therapy and 8 received drug therapy.And we divided them into HIT group (44, median age 57.5, 23 females ) and non-HIT group ( 198, median age 63.5, 87 females ) according to clinical diagnosis.Quantitative data was analyzed by independent t-test or Mann-Whitney U test.Qualitative data was analyzed by Fisher′s exact test.We drew ROC curve according to the statistical analysis to determine the optimal threshold value of antibodies in diagnosis of HIT andsensitivity , specificity, negative likelihood ratio, positive likelihood ratio of the HIT antibody detection .Therefore, we can assess the value of HIT antibody detection in HIT clinical diagnosis and treatment .Moreover, we used the optimal threshold value of antibodies to testify the suspected HIT patients .Results The HIT antibody concentration of HIT group (44) and non-HIT group ( 198 ) are 3.2 ( 95% CI:1.8 -5.5 ) U/ml and 0.4 ( 95% CI:0.3 -0.4 ) U/ml, respectively.The concentration of HIT group is much higher than the non-HIT group(P<0.000).When the cut-off value of HIT-Ab is set at 0.9 U/ml, sensitivity and specificity are 93.2%and 91.9%, respectively. And negative likelihood ratio and positive likelihood ratio are 0.07 and 11.53, respectively.When the cut-off value of HIT-Ab is set at 0.6 U/ml, sensitivity and specificity are 100.0%and 73.7%.HIT-Ab and 4T′s score of ROC-AUC are 0.971 and 0.745, respectively.The diagnosis value of HIT-Ab in HIT is significantly higher than the 4T′s score ( P<0.000).Conclusions HIT antibody detection is a simple and effective auxiliary diagnostic method in HIT exclusion .And HIT antibody detection is more optimal than the 4T′s score in HIT diagnosis and treatment .

Objective:By using balloon occlusive hepatic angiography in cirrhotic portal hypertension to evaluate contrast doses on the detection rate of intrahepatic venous-lateral branch shunt (HVVC), and the effect on hepatic venous pressure gradient (HVPG) and portal vein pressure gradient (PPG).Methods:From Jan 2018 to Jun 2021, 131 patients received transjugular intrahepatic portosystemic shunt (TIPS) at Beijing Shijitan Hospital.Results:A positive correlation between PVP and weged hepatic venous pressure (WHVP) ( r=0.241, P=0.001) was found when only by right hepatic vein approach. Ten ml of iodine contrast medium when compared to 5ml doses found more cases of intrahepatic venous-venous lateral branch shunt. The mean PPG of patients with HVVC was significantly higher than the mean of HVPG( P<0.05).The right hepatic vein was the only reliable vein by which WHVP was measured. Conclusions:Right hepatic vein manometry,adequate ballon occlusion and using 10ml of iodine contrast help get reliable WHVP and found HVVC; HVVC can affect the consistency of HVPG and PPG.
