Objective To investigate the effects of continuous infusion of moderate dose tranexamic acid and ulinastatin on fibrinolysis during orthotopic liver transplantation (OLT).Methods Thirty ASA Ⅲ or Ⅳ patients aged 34-63 yr with a body mass index of 17-37 kg/m2 and end-stage liver disease score 6-34,undergoing OLT,were randomly assigned to one of 3 groups ( n =10 each):group control (group C) ; group tranexamic acid (group T) and group ulinastatin (group U).The patients received continuous infusion of normal saline at 10 ml/h in group C or ulinastatin at 100 000 U/h in group U immediately after tracheal intubation until 120 min after portal vein was declamped,while in group T the patients received a loading dose of tranexamic acid 1 g followed by continuous infusion at 10 mg· kg-1 ·h- 1.Prothrombin time (PT),activated partial thromboplastin time (APTT),international normalized ratio ( INR),fibrinogen (Fg),D-dimers (D-D) and fibrin degradation product (FDP) were measured before induction of anesthesia (baseline),at 120 min after skin incision,30 min after clamping of portal vein (anhepatic phase),30 and 120 min after declamping (neohepatic phase) and at the end of operation.The amount of blood loss and transfusion were recorded.The patients were followed up after operation for hepatic artery and portal vein thrombosis in groups U and T.Results There were no significant differences in PT,APTT,Fg,INR and amount of blood loss and transfusion among the 3 groups.The plasma D-D concentration and percentage of patients with plasma FDP ＞ 20μg/ml were significantly lower in group T than in group C.There were no significant differences in plasma D-D concentration and percentage of patients with plasma FDP ＞ 20 μg/ml between groups U and C.No hepatic artery and portal vein thrombosis was detected after operation in groups T and U.Conclusion Continuous infusion of moderate dose tranexamic acid can inhibit fibrinolysis during OLT,but can not reduce the amount of blood loss.Continuous infusion of ulinastatin ( 100 000 U/h) has no significant effect on fibrinolysis during OLT.

Insulin resistance likely plays a central pathogenic role in polycystic ovary syndrome and may explain the pleiotropie presentation and involvement of multiple organ systems.Hyperinsulinaemia leads to increased production of androgens resulting in anovulatory infertility.Women,especially those obese women with polycystic ovary syndrome,have an increased risk of developing type 2 diabetes and cardiovascular disease in their later life.Treatment of insulin resistance through lifestyle therapy or with a diabetes drug has become mainstream therapy to reduce the risk of diabetes,endometrial abnormalities,and cardiovascular disease events in women with polycystic ovary syndrome.

Objective To investigate the influence of negative emotion on patients with peptic ulcer and their cognition about self-management knowledge. Methods Zung self-rating depression scale (SDS), self-rating anxiety scale(S/IS) and self-designed survey questionnaire of peptic deer patients' gen-end knowledge were used to examine 105 peptic ulcer patients in outpatient and inpatient in the digestive department and the data were compared with those of 106 healthy people. Results The peptic ulcer pa-tients' total score of SDS and SAS, and the occurrence rate of positive symptom were obviously higher than those of healthy people. In the group of ulcer patients, we compared the data of SDS one by one, the emo-tion of patients was different when their profession was different. The difference between patients with and without anxiety in keeping emotion steady and appropriate diet was significant. 45.8%～78.1% of patients with negative emotions didn't understand the cycle of treatment, regular consultation with a doctor or com-plication. Conclusions Nurses should evaluate the emotional state of patients, establish nursing plan based on individual patients, give different nursing and education to different patient. Thus patients' general self-management knowledge and compliance can be improved, their spirit health level can be alleviated. It can also reduce incidence of the disease and prevent relapse.

AIM: To investigate the changes of gene expression of vascular endothelial growth factor(VEGF) in norepinephrine/ burn serum-induced astrocytes.METHODS: Immunofluorescence staining was used to show the distribution of VEGF in astrocytes after 24 h using norepinephrine/burn serum stimulation.Western blotting was used to detect protein expression of VEGF.Real time PCR was used to investigate expression of VEGF mRNA.RESULTS: ① Green fluorescence of protein expression of VEGF in astrocytes was increased when treated with high dose norepinephrine(50 ?mol/L).Green fluorescence of protein expression of VEGF in astrocytes was increased distinctness after burn serum stimulation.Green fluorescence protein expression of VEGF in astrocytes was increased significantly when high dose norepinephrine combined with burn serum stimulation was added.② VEGF protein expression in burn serum stimulating group was increased,and VEGF protein expression was significantly increased when burn serum was added during moderate(20 ?mol/L),high dose norepinephrine stimulation.③ Expression of VEGF mRNA was increased in burn serumtreated astrocytes.Expression of VEGF mRNA was increased significantly when norepinephrine-stimulated astrocytes exposed to barn serum,and as norepinephrine dose increases gradually.CONCLUSION: Norepinephrine and burn serum play an important role in inducing VEGF protein expression in astrocytes,suggesting that stress reaction of postburn is an important cause in inducing brain edema by excreting VEGF in astrocytes.

AIM: To investigate the effect of norepinephrine (NE) on brain tissue VEGF protein expression in 24 h after severe burns. METHODS: (1) 40% total body surface area (TBSA) Ⅲ? burn model was made in Wistar males rats. Brain water (%) was examined at 24 h after burn. (2) NE levels in the rat brain tissue were determined by high performence liquid chromatography. (3) VEGF protein levels in the rat brain tissue were determined by Western blotting at 24 h of postburn. RESULTS: (1) Brain edema exhibited at the burns and burn with norepinephrine groups. (2) A increase in NE levels in the rat brain tissue was observed at the burns. NE levels increased significantly in burn with norepinephrine groups. (3) VEGF protein expression in the rat brain tissue was gradually increased with increasing in norepinephrine stimulating dose. VEGF protein expression in the burn rats brain tissue was significantly increased in burn with high dose of norepinephrine stimulation. CONCLUSION: Norepinephrine induced VEGF protein expression in rat brain tissue at 24 h after severe burn, suggesting that increases in norepinephrine level postburn induce brain edema.
