ABSTRACT
Objective To explore the clinical application value of S100B and vWF:Ag levels in ischemic cerebral apoplexy disease.Methods The plasma and clinical data from 85 cases of patients with ischemic cerebral apoplexy were collected,extracted 38 cases of volunteer blood plasma from a random sample of the general population and quantitative detected S100B levels by ELISA method,using Sysmex CA-7000 automatic blood coagulation instrument to detect plasma vWF:Ag levels.The carotid artery diameter and intima-media thickness of all the participants were detected by GELOGIC9 color doppler ultrasonic diagnostic instrument.Results The levels of plasma vWF:Ag in the CS group,the NCS (％) group and the control group were 176.8±56.3,128.9±37.6 and 93.7±30.1,which of plasma S100B (μg/L) were 2.8±1.3,1.9±0.9 and 1.3 ±0.7.Stroke patients could be divided into CS group and NCS group,compared with control group,observed the changes and the relationship of ischemic stroke disease for plasma S100B and vWF:Ag levels.The levels of plasma vWF:Ag and called S100B in the two case groups were increased compared with those in controls,the differences had statistical significance (F=125.9,89.3,P＜0.01).In CS and NCS group,vWF:Ag and S100B were comparative differences and statistically significant (F=125.9,89.3,P＜0.01),the levels of the two markers in the CS group were higher than in replication group.In CS group,the plasma levels of vWF:Ag and S100B were positively correlated (r=0.836,P＜0.01).In CS group,plasma levels of vWF:Ag were associated with carotid artery diameter and intima-media thicknes (r=-0.853,0.923,P＜0.01 and r=-0.783,0.823,P＜0.01),which of S100B did so (r=-0.820,0.833,P＜0.01).Conclution Detection of the levels of vWF:Ag and S100B can predict the degree of danger of ischemic cerebral apoplexy disease and estimate the development of the disease.
ABSTRACT
Objective To study the variation characteristics of plasma von Willebrand factor antigen (vWF Ag) after the off-pump coronary artery bypass graft (OPCAB) and its predictive value on the assessment of cardiovascular ischemia events in the postoperative patients.Methods A total of 338 patients with non-ST-segment elevation myocardial infarction were selected from 2010 to 2012 in this retrospective cohort study,with 249 males and 89 females and a mean age of (69.2 ± 4.5) years.The level of vWF Ag was assayed by the IL ACL-TOP 700 blood coagulation instrument.Receiver-operator curve (ROC) analysis of vWF Ag levels in the prediction of risk of ischemic events was performed.x2 test and Logistic regression were conducted to analyze the relevance between vWF Ag and clinical pathological factors.Cox regression analysis model were used to evaluate the effect on prognosis.Results There was significant difference in vWF Ag level at different time point between the poor recovery group and the stable disease group (x2 =129.53 and 101.48 respectively,both P＜0.01).And the vWF Ag level was higher in the poor recovery group on the 14th,30th,60th,90th day after OPCAB than in the stable disease group at the same time points respectively (all P＜0.05).The optimum cut-off point of vWF Ag (the 30th day after OPCAB) for prediction of ischemic events was 251 ％ within the 31-90th day after OPCAB,the area under ROC curve was 0.839 (95％ confidence interval:0.776-0.902).The Logistic regression analysis showed that the vWF Ag level on 30th day after OPCAB was affected by age,left ventricular ejection fraction,left main artery disease,serum creatinine level,vascular number of bypass grafts,history of myocardial infarction and hypertension (all P＜0.01).The Cox analysis showed that the cut-off value of vWF Ag (on the 30th day after OPCAB) was the independent prognostic assessment parameter for ischemic events in patients with cardiovascular diseases within one year.Conclusions The variation of serum vWF Ag level can reflect the integrated influence of multiple pathological factors on vascular endothelial function after the OPCAB,it can become the effective predictor for disease progression within 90 days and the long-term prognosis after OPCAB.
ABSTRACT
Objective To study the effects of the effective composition of Angelica sinensis injection on the functional state of platelet in patients with ulcerative colitis (UC),and its significance of therapy.Methods In 64 patients with UC and 30 healthy people, a-granule membrane protein (GMP-140), thromboxane B 2(TXB 2), 6-keto-PGF 1a were detected by means of ELISA.Platelet adhesion rate was detected by the platelet adhesion meter, von willebrand faetor related antigen (vWF:Ag) was also detected by the means of monoclonal -ELISA.Results The indexes of platelet activation and vWF:Ag in patients with UC were significanrly higher than those in the control group (P
