Clinical study of continuous external drainage combined with intrathecal infusion of urokinase in prevention and treatment of cerebral vasospasm after aneurysm / 中国生化药物杂志

Objective To explore the persistent cerebrospinal fluid drainage and intrathecal injection of urokinase in prevention and treatment of cerebral vasospasm after aneurysm surgery.Methods The effect of prevention and treatment of cerebral vasospasm after aneurysm surgery in 40 patients, using the method combined with intrathecal injection of urine kinase for persistent cerebrospinal fluid drainage, and classified as the observation group;the other 40 cases patients with persistent cerebrospinal fluid drainage intervention, and classified as the control group, two groups of patients were in Shandong Provincial Hospital from January 2016 to January 2017.Results The incidence of rebleeding in two groups had no significant difference in observation of cerebral vasospasm in patients with the incidence was significantly lower than the control group, the observation The incidence of cerebral vasospasm group was 15.0%, 37.5% in the control group, compared two groups of patients with the prognosis, the obvious observation group of patients with good prognosis, comparison between groups showed significantly(P<0.05).Conclusion Persistent cerebrospinal fluid drainage and intrathecal injection of urokinase on the clinical study of postoperative cerebral vasospasm aneurysm found the simple, compared with continuous drainage of cerebrospinal fluid, can improve the clinical condition of patients, and promote the recovery of patients, reduce cerebral vascular spasm, so it is worthy of reference.

Changes of splenic T-lymphocyte subsets in rats with acute pancreatitis / 中国现代普通外科进展

Objective: To examine T-lymphocyte subsets of peripheral blood and splenic cells in rat with acute pancreatitis(AP),to investigate the changes of immune functional status in the development of acute pancreatitis.Methods: AP model was developed in adult male rats by retrograde injection of 4% sodium taurocholate in the pancreatic duct.T-lymphocyte subsets( CD3,CD4,CD8) of peripheral blood and splenic cells was measured by Flow Cytometer.Results: There was no singificant change in the stage of MAP.In the stage of SAP,the levels of CD3 and CD4 and CD4/CD8 of peripheral blood were decreased,the decrease of T-lymphocyte subsets in splenic cells was more obvious than those in peripheral blood.Conclusion:Spleen shows a negative immunologic function in the stage of SAP and promote the development of AP.
