Objective To investigate the significance of the expression of interleukin-10(IL-10),interleukin-13(IL-13)and interleukin-15(IL-15)in serums of patients with hepatitis B.Methods The expression of IL-10,IL-13 and IL-15 in serums of 109 patients was measured by ELISA.Results The serum levels of IL-10,IL-13 in patients with moderate degree chronic hepatitis B(CHB)group were significantly higher than that in patients with chronic severe hepatitis group,severe degree CHB group,acute hepatitis group and normal group.The serum level of IL-15 was increased in patients with acute hepatitis、moderate degree CHB group,severe degree CHB group and chronic severe hepatitis compared with normotensives.The proportion of IL-15/IL-10 and IL-15/IL-13 in patients with chronic severe hepatitis group,severe degree CHB group and acute hepatitis group were higher than that in patients with moderate degree CHB group and normotensives.The serum level of IL-15 and the proportion of IL-15/IL-10 and IL-15/IL-13 in dead group were significantly higher than that in improving group with chronic severe hepatitis.Conclusion There is an abnormal cell-mediated immune response in patients with hepatitis B.Combining detection on the levels of serum IL-10,IL-13 and IL-15,and the proportion of IL-15/IL-10 and IL-15/IL-13 would nicely show the cellular active status and be helpful to the prediction of prognosis and direction of therapy in patients with hepatitis B of different kinds of clinical type.

Objective To explore the prognostic factors of nosocomial infection in severe hepatitis and liver cirrhosis,and to assess its prevention and treatment.Methods A prospective study of nosocomial infection of severe hepatitis and liver cirrhosis was carried out in our hospital from Apr.1996 to Dec.2000.The prognostic factors of nosocomial infection in severe liver diseases was analyzed by logistic regression.Results The mortality of nosocomial infection in severe liver was 37 36%(34/91).Multiple regression analysis showed that prognosis was in order variables related to follow factors:Serum bilirubin,prothrombin time,complement C3,serum cholesterol,serum sodium,white blood cells count,polymorphonuclear cell rate,the kinds of nosocomial infection,severe complications and improper medical manipulations.The prognostic factors high correlated with nosocomial infection via analysis by logistic analysis were as follows:low serum complement C3 and low cholesterol.Conclusions The nosocomial infection were important factors that cause highly mortality in severe liver diseases.The prognositic factors high related with nosocomial infection of severe liver diseases were:low serum complement C3 and cholesterol level.

OBJECTIVE To study the antimicrobial susceptibility and distribution of the ?-lactamases producing Escherichia coli from hepatopathy patients.METHODS Thirty-six ?-lactamases producing E.coli strains from hepatopathy patients were detected with a multi-disk test(synergy test,antagonized test for the inducible AmpC ?-lactamases(IABLs)),AmpC ?-lactamases(ABLs)phenotype test and extended-spectrum ?-lactamases(ESBLs) comfirmation test,and the susceptibility of antimicrobial agents with K-B test.RESULTS Twenty-six strains of 38 strains produced the ?-lactamases(68.4%),13(34.2%)strains produced penicillinases,5(13.2%)strains produced broad-spectrum ?-lactamases or penicillinases and 8(21.1%)strains produced ESBLs alone.All were not detected out to produce ABLs and carbapenem-hydrolyzing ?-lactamases(CHBLs);All nonnproducing ?-lactamases strains were sensitive to 9 kinds of antimicrobial agents;but in the 26 strains producing ?-lactamases,the resistant rate to AMP,KZ,FTX,IMP,AK,CN,CIP,SXT and TET were 100.0%,50.0%,30.8%,0,61.5%,15.4%,73.1%,61.5%,and 69.2%,respectively.CONCLUSIONS The rate of ?-lactamases producing E.coli from hepatopathy patients is high.The main types of ?-lactamases are penicillinases and ESBLs.Most strains producing ?-lactamases are susceptible to imipenem and amikacin.

Objective To evaluate the effectiveness of prophylactic antibiotic therapy on nosocomial infection in patients with severe viral hepatitis,and inquire into its applied mechanism.Methods 159 cases of severe viral hepatitis were divided into groups according to clinical stage and the applied circumstance of antibiotic medicine;Group A:receiving no prophylactic antibiotics therapy,Group B intravenous injection of the third generation cephalosporins and Group C intravenous injection of the semisymthetic penicillins.All cases had no infection on admission and received no antibiotics for 7 days before entering hospital and had stayed in hospital over 72 hours.Results Nosocomial infection occurred in 76 patients among the 159 selected cases.The incidence of nosocomial infection of Group A,Group B and Group C was 56.16%(41/73),34.0%(17/50) and 50.0% (18/36),respectively.The occurring time of nosocomial infection of Group B in early,middle and late stage patients with severe viral hepatitis was significantly later than Group A.The incidence of nosocomial infection in middle and later stage patients was significantly lower,and the mortality was significantly decreased in middle stage patients.There was significantly difference between group A and B(P0.05).Conclusion Prophylactic usage of antibiotics of third generation cephalosporins can not only delay nosocomial infection but also decrease the incidence of nosocomial infection in middle and late stage patients and mortality in middle stage patients with severe viral hepatitis.

Objective To investigate the relationship between lipopolysaccharide binding protein(LBP) in serum and degree of hepatic inflammation. Methods The levels of LBP in serum of 99 patients with chronic viral hepatitis (CVH) were detected by ELISA. The levels of LBP in 33 of all patients with chronic severe viral hepatitis were further detected 2～4 weeks after treatment. Results The serum levels of LBP in patients with chronic viral hepatitis were higher than that in normal patients [(79.62?45.52) ng/ml vs (50.22?31.44) ng/ml, P=0.001]. The serum levels of LBP in patients with chronic severe viral hepatitis were significantly higher than that in patients with moderate degree CVH group, severe degree CVH group, and normal group (P

Objective To investigate the relationships between the severity of non-alcoholic fatty liver disease (NAFLD) and metabolic syndrome (MS).Methods One hundred and twenty-seven cases of NAFLD patients were selected from March 2011 to August 2012 in the First Hospital Affiliated to Fujian Medical University,of them,61 patients with mild NAFLD,45 patients with moderate and 21 patients with severe.And 21 cases without NAFLD were selected as control group during the same hospitalized period.All objects received the measures of height,body weight,waist circumference (WC),blood pressure; Liver ultrasonic examination,the examination of fasting plasma glucose,blood fat and hepatic function detections were also handed by special people.Results The proportion of overweight in the control group and the three NAFLD subgroups were 57.1％ (12/21),88.5％ (54/61),95.6％ (43/45) and 100％ (21/21) respectively (x2 =18.376,P ＜0.001) ;The proportion of the obesity in control group and the three NAFLD subgroups were 19.0％ (4/21),44.3％ (27/61),64.4％ (29/45) and 71.4％ (15/21) respectively(x2 =16.440,P =0.001).The proportion of the metabolic syndrome of the control group and the three NAFLD subgroups were 14.3％ (3/21),45.9％(28/61),71.1％ (32/45) and 71.4％ (15/21) respectively (x2 =22.637,P ＜ 0.05).All three subgroups of NAFLD were higher than the control group (x2 =6.641,P ＜ 0.05 ; x2 =18.562,P ＜ 0.05 ; x2 =14.000,P ＜0.05,respectively).The severity of NAFLD was positively correlated with BMI,WC,TG,FBG,SBP,and DBP (r =0.467,0.503,0.386,0.369,0.279,0.295,P ＜ 0.01),and negatively correlated with HDL-C (r =-0.209,P ＜0.05).Conclusion The severity of NAFLD had significant correlations with metabolic syndrome's components.
