Objective To investigate the effect of insulin combined with Edaravone therapy on delayed cerebral vasospasm (CVS) after experimental subarachnoid hemorrhage (SAH).Methods 40 New Zealand white rabbits were randomly separated into sham-operated group (n=8),SAH group (n=10),insulin group (n=10) and insulin+Edaravone group(n=12).SAH models were made by injecting blood twice into cisterna magna.30 min later of the first blood injected,the insulin 0.2 U/kg was subcutaneous injected in insulin group and insulin+Edaravone group,3 times daily for 7 d;while,the insulin+Edaravone group received Edaravone 0.5 mg/kg (intravenous injected in ear vein) twice a day for 7 d.7 d after the model made,the basilar artery cross sectional area was measured and the pathological changes were obseved to estimate the degree of CVS.The expression of insulin receptor(InRa) in vascular endothelial cell was detected by immunohistochemical staining.Results The basilar artery cross sectional area between insulin+Edaravone group[(0.46?0.3)mm2]and the sham-operated group[(0.48?0.4)mm2] was no significant difference;but they were obviously bigger than those in SAH group[(0.25?0.3) mm2] and the insulin group [(0.30?0.3)mm2](all P

Objective To compare the clinic significance of four clinical scoring systems in evaluating prognosis of acute pancreatitis: bedside index for severity in acute pancreatitis(BISAP), acute physiology and chronic health evaluation (APACHEⅡ), Ranson’s scoring system, computed tomography severity index (CTSI) in AP. Methods Patients visited our clinic with AP (n=114) in recent 2 years were retrospectively analyzed. BISAP and APACHEⅡscores were obtained at 24 hours after admission; Ranson ’s score was obtained at 48 hours after admission and CTSI are obtained was obtained at 72 hours after admission. Results of four scoring system were compared under different causes and different severity of the dis?ease. Correlation between BISAP score and the other three scores were analyzed and the predicative value of all four scoring systems for severity of AP and death were also compared. Results The mean values of four scoring systems show no signifi?cant difference in AP patients with different etiology (P>0.05). The BISAP score is positively correlated with APACHE-Ⅱ, Ranson ’s score and CTSI score (P<0.01). The four scoring systems all present good predictive value on the severity of AP and death (P<0.01). Conclusion The four scoring systems can all be applied to grading and prognosis for AP of various causes. BISAP is a simple, prompt, economical scoring system in clinical practice.

Objective:? N oxalo L ?,? diaminopropionic acid were isolated from the powder of red ginseng. its physiological characteristics were studied. Method:This material is obtained by CM Sephadex C 25 and FPLC MonoQ. We have examined the effect of ? N oxalo L ?,? diaminopropionic acid on contraction of artery of guinea pig. Result:When histamin and adrenalin do not exist, there is neither contraction nor relaxation. It can strengthen induction of contraction of artery of guinea pig, but it has no such effect on adrenalin. Besides, it doesn't induce plaque coagulation through adrenalin, ADP blood coagulation enzyme and collagen. It doesn't suppress the transformation from tension peptide of blood vessel to enzyme.Conclusion:Hemostatic effect of ? N oxalo L ?,? dlaminopropinomie acid may caused by vesseles contraction through promoting Histamine.
