BACKGROUND: With the deep investigations of pathophysiological mechanism of acute cerebral infarction, it is discovered that inflammation occupies an important stance in the ischemic injuries of central nervous system ( CNS ), in which tumor necrosis factor-αt (TNF-α), interleukin- 1β(IL-1β), and soluble intercellular adhesion molecule(sICAM-1) become hotspots in the researches.OBJECTIVE: To investigate the relationship between the levels of serous inflammatory cell factors and the course of the disease, the severity of the situation in patients with ischemic stroke.DESIGN: A case-control study based on patients and healthy individuals.SETTING: Department of neurology in a university hospital.PARTICIPANTS: Fifty ischemic stroke patients including 23 males and 27 females with an average age of(60.26 ± 8.77) years old were selected from the outpatient and inpatient Departments of Neurology of the Renmin Hospital of Wuhan University between January 2001 and December 2003. Forty healthy controls including 18 males and 22 females with an average age of (61.05 ± 8.09) years old were selected from the subjects who had physical check up at outpatient department during corresponding period.INTERVENTIONS: Serous TNF-α, IL-1 β and sICAM-1 levels were detected by double-antibody-ELISA.MAIN OUTCOME MEASURES: Serous levels of TNF-α, IL-1β and sICAM-1 in patients with ischemic stroke of different stage, with different infarction volume and different neural functional defects.RESULTS: Serous TNF-α, IL-1β and sICAM-1 levels of patients with cerebral infarction during acute phase and convalescence were significant higher than that of control group( P ＜ 0.01 ), and the levels was significantly higher in acute phase than convalescence ( P ＜ 0.05 ) . The elevation was closely correlated with the degree of neural functional defect and the size of infarction volume, and furthermore, the serous content of TNF-α was also correlated with IL-1β and sICAM-1 levels.CONCLUSION: TNF-α, IL-1β and sICAM-1 interact and participate in the inflammation and reperfusion injury of acute cerebral infarction. Surveillance on them can provide experimental indicators for early clinical therapy and rehabilitative intervention, which is good for the control of the development and recurrence of stroke.

Objective: To study the surgical strategy of portal vein organized thrombosis ( PVOT ) during liver transplantation ( LT ) . Methods: The clinical data of 41 patients with PVOT performed LT from January 2005 to June 2006 ( 359 cases ) in our institute was retrospectively analyzed . The reconstruction of portal vein ( PV ) were removing thrombosis in 22 cases , throm- boendovenectomy in 10 cases , PV to splanchnic varicose vein in 8 cases , cavoportal hemitranspo- sition in 1 case . Results: 1 case died of multiple organ failure , 1 case died of hepatic artery bleeding . Retransplantation and portosystemic shunt vein ligation were performed in 1 case 14 days after LT because of its insufficient PV flow 2 cases were found anastomotic stenosis and they were cured by balloon angioplasty and stent placement via hepatic vein . Other patients were followed up 6 to 20 months , all of them had normal PV flow . Conclusion: Thromboen- dovenectomy or removing thrombosis is applicable to manage PVOT during LT .

Objective To compare the impact of the sirolimus and tacrolimus on the tumor recurrence after liver transplantation due to HCC beyond Milan criteria.Method Sixty-one liver transplantation recipients due to HCC beyond Milan criteria,between Jan.2008 and Apri.2012,were randomized,with the informed consent,into two different immunosuppression groups: sirolimus group (n=30) and tacrolimus group (n=31).In tacrolimus group,tacrolimus was used as the basic immunosuppressant,methylprednisolone was discontinued within one month postoperatively,and mycophenolate mofetil was used within the dosage of 1.5 g/d accordingly.In sirolimus group,the immunosuppresive scheme was the same as that of the tacrolimus group within postoperative one month,and from that,tacrolimus was transferred to sirolimus.No antineoplastic agents were given before tumor recurrence.The tumor recurrence rate and the survival rate of the recipients were compared between the two groups.Result The median follow-up duration was 35.2 months (10.3～ 60.2).The tumor recurrence rate at postoperative year 1,2,3 and 4 in the sirolimus group (13.3％,36.7％,43.3％ and 53.3％) was significantly lower than that in the tacrolimus group (38.7％,67.7％,74.2％ and 77.4％),P ＜ 0.05 for all.The one-year survival rate in the recipients postoperation had no significant difference between sirolimus group and tacrolimus group (90.0％ vs.87.1％,P=0.438).The 2-,3-and 4-year survival rate in the recipients was significantly higher in the sirolimus group (53.3％,33.3％ and 20.0％) than that in the tacrolimus group (41.9％,22.6％ and 9.7％),P ＜ 0.05 for all.The liver function and renal function of the recipients at the postoperative year 1,2,3 and 4 showed no significant difference between the two groups,P＞0.05.Conclusion In comparison with tacrolimus,sirolimus could significantly reduce the tumor recurrence rate and increase the survival rate for the liver transplant recipients due to HCC beyond Milan criteria.
