0.05).Conclusions Our results suggest that ascites contributes to the exaggerated fibrinolysis in cirrhosis, whereas cirrhosis self, in the absence of ascites, leads to a slightly fibrinolynic state. The t-PA/PAI imbalance was not a main cause of hyperfibrinolysis in patients with cirrhosis.

AIM:To study the role of heme oxygenase (HO)-1 in the mechanism of cholecystokinin-octapeptide (CCK-8) for attenuation of acute lung injury (ALI) induced by lipopolysaccharide (LPS). METHODS: Adult male rats were randomly divided into five groups: control group, LPS group, CCK-8+LPS group, LPS+ Hm (hemin, HO-1 donor) group and LPS+ZnPP (zinc protoporphyrin, specific inhibitor of HO-1) group. PMN number in bronchoalveolar lavage fluid (BALF), the structure of the lung, MDA content, HO-1 activity, the expressions of HO-1 mRNA and protein in the lung were detected respectively. RESULTS: The lung injury in LPS group was observed, at the same time the numbers of PMN, the content of MDA, the activity and the expression of HO-1 were all higher than those in control group (all P

Objective To evaluate the relationship between emergence agitation (EA) during recovery from general anesthesia and postoperative cognitive dysfunction (POCD).Methods Two hundred and eighty ASA Ⅰ or Ⅱ patients,aged 18-70 yr,weighing 52-80 kg,undergoing elective surgery,were included.Anesthesia was induced with midazolam,fentanyl,propofol and cisatracurium.The patients were tracheal intubated and mechanically ventilated.Anesthesia was maintained with remifentanil,propofol and cisatracurium.EA was assessed at 15-40 min after extubation by using Post-operative Quality Recovery Scale and the cognitive function was assessed at day 1 before operation and days 1-7 after operation.Patients were divided into POCD or nonPOCD group according to the occurrence of POCD.The general data of patients,preoperative complications and types of surgery were recorded.If there was significant difference between the 2 groups,the factor was analyzed using multi-factor logistic regression to select the risk factor for incidence of POCD.Results The incidence of POCD was 40.7 ％.The results of logistic regression analysis showed that the dangerous degree of the risk factors for POCD in order from high to low were emergence agitation,duration of anesthesia and age.Conclusion EA during recovery from general anesthesia is an independent risk factor for POCD.

BACKGROUND:Skeletal muscle satelite cels are muscle-derived stem cels with proliferation and differentiation potential distributing between the muscle cel membrane and the base film. Studies have shown that skeletal muscle satelite cels are of efficacy and safety, but the survival rate of the transplanted stem cels is very low, which greatly limits the application of skeletal muscle satelite cels. OBJECTIVE: To observe the effects of Fasudil on apoptosis of skeletal muscle satelite cels induced by H2O2. METHODS: Skeletal muscle satelite cels cultured in vitro were randomly divided into three groups including H2O2group, H2O2+Fasudil group (Fasudil group) and control group. Apoptosis rates were observed by flow cytometry. The concentrations of interleukin-4 and tumor necrosis factor-a in each group were detected by ELISA. Western blot was employed to measure the protein level of Bax in each group. RESULTS AND CONCLUSION: Compared with the H2O2group, a significant decrease was found in the apoptosis rate of cels, protein level of Bax, and concentrations of interleukin-4 and tumor necrosis factor-a in the Fasudil group (alP < 0.05). These findings indicate that Fasudil can play anti-apoptosis protection by inhibiting Rho-kinase signaling pathway, which may be related to the reduced expression of Bax.

Objectives To explore the role of hydrogen sulfide(H_(2)S) in lipopolysaccharide(LPS)-induced acute lung injury(ALI) in rats and the underlying mechanisms.Methods Sixty-four Sprague-Dawley rats were randomly divided into four groups: control,LPS(instilled intratracheally to induce ALI),NaHS(H_(2)S donor)+LPS,propargylglycine [inhibitor of cystathionine-?-lyase(CSE),PPG]+LPS.Animals were sacrificed at(4 h) or 8h after agent administration.Lung weight/body weight ratio(LW/BW) was measured and calculated.Morphological changes of lung tissues were observed,H_(2)S concentration and carbon monoxide(CO) level in plasma were tested.Malondialdehyde(MDA) content,CSE activity and heme oxygenase(HO) activity of the lung were determined.Immunohistochemisty technique was performed to examine the expression and the absorbance value of(HO1) protein in lung tissues.Results Compared with control conditions,severe injuries of lung tissues and a raised LW/BW and MDA content were observed in rats treated with LPS.LPS also lead to a drop in plasma H_(2)S concentration and lung CSE activity.The enzyme activity of HO,the protein expression of(HO-1) and plasma CO level increased after LPS instillation. Administration of NaHS before LPS could atten-uated the changes induced by LPS.Pre-administration of PPG exacerbated the injuries induced by LPS,but there was no prominent variation in CO level,HO activity and(HO-1) protein expression compared with those of LPS group.Conclusions Downregulation of H_(2)S/CSE was involved in the pathogenesis of acute lung injury induced by LPS.Exogenous(H_(2)S) provided protection against the lung injuries to some extent,which may be explained by its anti-oxidative effects and the upregulation of CO/(HO-1) system.

Objective:To observe cellular,humoral and mucosal immune responses induced by DNA-or protein-based of FimH of UPEC type 1.Methods:After mice were immunized respectively with recombinant plasmid pcDNA3.1/fimH or pcDNA3.1/fimC,and the combinant FimH and FimC protein,the anti-FimH protein IgG of sera and SIgA in bladders were detected by ELISA.The lymphocyte phenotypes of CD3,CD4 and CD8 were analyzed by FCM.Results:The titers of IgG in sera and SIgA in the bladders were all low in the group immunized by recombinant FimH plamid,but the percentage of CD4+T cells in spleen was high,which revealed that recombinant FimH plamid was able to trigger better cellular immune response.The titers of IgG were very high in the group immunized by FimH protein,which suggested that the FimH protein was able to trigger better humoral immune response,but SIgA in the bladders was not detectable.Conclusion:The DNA for FimH can induce humoral,mucosal and cellular immune response.FimH protein can only induce humoral immune response.FimC protein is able to enhance the immunogenicity of FimH protein.

AIM: To investigate the effect of H_2S on pulmonary artery hypertension during acute lung injury induced by LPS and the interaction between the systems of hydrogen sulfide (H_2S)/cystathionine-?-lyase (CSE) and nitric oxide (NO)/nitric oxide synthase (NOS) in this process. METHODS: Seventy-two adult male rats were randomly divided into four groups: control group, LPS group, LPS+L-NAME group and LPS+propargylglycine (PPG) group. Mean pulmonary artery pressure (mPAP) of each rat was examined at 2 h, 4 h, 6 h and 8 h after treatment. H_2S and NO contents in plasma, NO content, iNOS, cNOS and CSE activity in lung were measured at 4 h or 8 h after treatment, respectively. Expression of iNOS in lung tissue was also detected by immunohistochemistry technique, and the injury of lung was evaluated with morphological changes under microscope. RESULTS: LPS could induce severe lung injury, and mPAP, NO content, iNOS activity and its protein expression in LPS group significantly increased, but cNOS activity, H_2S content and CSE activity decreased compared with those of control group. Administration of L-NAME before LPS could attenuate the changes induced by LPS. Pre-administration of PPG, a CSE inhibitor, exacerbated the injury by LPS, but there was no prominent variation in cNOS activity. CONCLUSION: Reduced endogenous H_2S could increase pulmonary artery hypertension during acute lung injury induced by LPS. There is a negative effect between H_2S/CSE system and NO/NOS system in this process.
