Objective To investigate the effect of plasma exchange (PE) in the treatment of chronic severe hepatitis. Methods 70 cases with chronic severe hepatitis were divided randomly into two groups:treatment group and control group. The treatment group combined with PE based on combined therapy of internal medicine, control group was only performed combined therapy of internal medicine. The therapeutic efficient rate was analyzed by con-trast after one month. Results The level of TBil,ALT,CHO,CHE,PTA,BUN and Cr of patients in treatment group improved more obviously than those in control group(P <0.05). The total effective rate was 62.86% in treatment group and was 31.43% in control group,and there were significant differences in two groups(P <0.05). The death rate was 11.42% in treatment group and was 31.42% in control group,there were significant differences in two groups (P < 0.05). Conclusion PE combined with therapy of internal medicine can obviously improve therapeutic efficient rate of chronic severe hepatitis,which is an safe and effective method.

Objective To investigate the expression of human macrophage metalloelastase(HME) both in gastric cancer cell lines and gastric cancer tissues,and to find the role of HME in gastric carcino genesis.Methods Fifty eight patients who were operated in our hospital during April to Aug.2003 were enrolled.The samples taken from cancer,paracancer or normal tissues of these patients and cancer cell lines(MGC-803,SGC-7901,AGS)were detected for HME protein and HME mRNA expressions by Western blot and immunohistochemistry,RT-PCR and fluorescence quantitative PCR,respectively. Results Both HME mRNA and HME protein expressions were found in all three gastric cancer cell lines.The expressions of HME mRNA and HME protein in gastric cancer tissues was increased signifi- cantly compared with that in normal tissues(P0.05).Conclusions The increased HME expression in gastric cancer tissures compared with normal tissue indicate that HME may be a potential tumor marker for gastric cancer.

Objective To investigate the expression of autophagy and the effect of complement C5a/C5aR pathway on autophagy induced by renal ischemia reperfusion injury (IRI).Methods MaleWT and C5aR gene knockout (BALB/C background) mice were selected.The model of renal IRI was established by occluding bilateral renal pedicles with microaneurysm clamps.Mice were divided into wild type BALB/C (WT) group and C5aR gene knock out (C5aRKO) group.The pathology of kidney was assessed by HE staining.The levels of BUN and KIM-1 were detected 24 h after reperfusion.The expression of the autophagy-associated protein (LC3 Ⅱ/LC3 Ⅰ and P62) was measured by Western blotting and immunofluorescence.In vitro,human renal tubular epithelial cells (HK2) were cultured.The expression of LC3 in HK2 cells was investigated by immunofluorescence and Western blotting after being treated with recombinant C5a or C5a combined with C5aR antagonist (C5aRA).Results As compared with WT group,the severity of kidney injury was obviously reduced in C5aRKO group (P＜0.05).After ischemia-reperfusion,the expression of autophagy-related protein LC3 gradually increased with the reperfusion time prolonged.The level of autophagy induced by ischemia-reperfusion was significantly reduced in C5aRKO group as compared with WT group (P＜0.05).In addition,the expression of autophagy-related protein LC3 Ⅱ in HK2 cells was increased with the augment of C5a stimulation concentration in vitro.Blockage of C5aR pathway by C5aRA led to a significant decrease in autophagy (P ＜ 0.05).Conclusion Complement C5a/C5aR pathway promotes renal IRI-induced autophagy.

Objective To dynamically observe the changes of subsets of splenocytes in mice by immunization with recombinant BCG-Eg95 vaccine of Echinococcus granulosus(Eg).Methods Balb/c mice were divided randomly into 3 groups according to their weishts:intranasal group.per os group and PBS control.The mice were vaccinated intranasally or orally by the vaccine respectively in experimental groups.and the control mice were given phosphate buffer saline intranasally.These mice were killed to get spleen on 0,2,4,6,8,10,12, 14,16 and 18 week of immunization,respectively.Splenocytes were separated to measure subsets of CD4+ and CD8+T ceUs by FACsort.Results There were marked differences in ratio of CD4+ and CD8+ subsets among the different groups(F value were 21.56 and 22.08 respectively,P＜0.05).There were very marked differences in ratio of CD4+ and CD8+ subsets in different weeks(F value were 5.75 and 6.29 respectively.P＜0.01).In the intranasal group,CD4+ and CD8+ T subsets increased obviously in 6～18 weeks and 12 weeks,and reached the highest level on 10 and 12 week,espectively.Their values were 0.348±0.013 and 0.090±0.003.respectively.There were marked or very marked differences(q value were 7.32 and 5.32 respectively,P＜0.01 or＜0.05)in comparison with 0 week(0.230±0.022 and 0.069±0.015).In the oral group,CD4+and CD8+ subsets rose reinarkablv on 6-16 weeks and 8-18 weeks,achieved the hishest level on 10 and 16 weeks,respectively.Their vahes were 0.405± 0.006 and 0.096±0.004,respectively.There were marked or very marked difference(q value were 7.53 and 5.35 respectively,P＜0.01 or＜0.05)in comparison with week 0(0.230±0.022 and 0.069±0.015).Conclusion CD4+and CD8+T subsets may play an important role in immune response induced in mice by rBCG-Eg95 vaccine.

Objective To investigate the changes of cytokines of splenocytes in mice immunized with recombinant BCG-Em Ⅱ/3 vaccine of Echinococcus multilocularis(Em)and consequently challenged with Em protoscoleces.Methods Balb/c mice were subcutaneously or intranasally vaccinated and challenged with Em were separated and cultured with EmAg,ConA or PHA,respectively.The supematants were gathered to measure the levels of IL-2,IFN-γ,TNF-α.and IL-4 by ELISA Kits.Results The levels of IL-2,IFN-γ,TNF-α and IL-4 in the subcutaneous group were(34.6±2.7),(34.5±2.8),(265.0 ±0.0)and(9.8±2.6)ng/L respeetively:those in the intranasal group were(32.5±2.2),(33.6±2.7),(130.0±0.0)and(10.4±27)ng/L respectively;those in the control were(25.0±1.9),(30.0±0.0),(10.0±0.0)and(12.5±2.7)ng/L,respectively:there were statistical differences between the immunized groups and control group(P＜0.01 or＜0.05);The level of TNF-α in the subcutaneous group was higher than that in the intranasal group.Conclusion Th1 response has been induced in mice vaccinated with rBCG-Em Ⅱ/3 vaccine and challenged with Em protoscoleces.

Objective To evaluate the effect of nitrous oxide(N2O) on the cuff pressure of ProSeal laryngeal mask airway(PLMA) in pediatric anesthesia. Methods Thirty-two pediatic patients were enrolled and divided into two groups randomly.PLMA cuffs were inflated with air(Group A) or 50% N2O/oxyen(Group N) to 20 mmHg as initial pressure.The intracuff pressure was monitored during anesthesia with 50% N2O in oxygen. Results Intracuff pressure increased to(40.6?9.3) mmHg in Group A and slightly decreased in Group N.Deflation volume in Group A was much more than that in Group N[(4.4?2.3) mL vs(2.6?1.0) mL,P

Objective To analyze the epidemiographic features of malignant tumors of urinary system in renal allograft recipients in our center.Methods A retrospective analysis was performed on 3150 patients who received renal transplantation between June 1978 and Autumn 2006.Twelve cases of urinary tumors were selected for study.Results Among 3150 recipients,33(1.05%)were diag- nosed as malignancies including 12(0.38%)cases in urinary system.The mean age of these patients when diagnosed as urinary tumors was 58.3?4.6(range 48-66).The mean duration of immunosup- pressive treatment was 62?18(range 26-120)months.Six cases received cyclosporine A+azalthio- prine+prednisone(CsA+Aza+Pred),5 cases cyclosporine A+mycophenolate mofetil+prednisone (CsA+MMF+Pred),and one case tacrolimus+mycophenolate mofetil+prednisone(FK506+MMF +Pred).Surgical treatment was carried out in 11 patients.Ten of them were still alive.One case died of cerebral hemorrhage.Conclusions Malignant tumors of urinary system,especially TCC is an im- portant complication in renal transplantation in our center.The occurrence of malignant tumors is inti- mately related to immunosuppressive treatment.The immunological status of patients after renal transplantation should be evaluated in follow-up studies.The treatment consists of complete resection of the mass,decreases of immunosuppressants,chemotherapy or radiotherapy.
