Objective To investigate the clinical features of patients with superinfection of HEV and HBV related acute on chro-nic liver failure(ACLF) .Methods Clinical data of 35 patients diagnosed with superinfection of HEV and HBV related ACLF and 37 patients diagnosed with HBV related ACLF were collected for this retrospective study .The liver and kidney function ,HBV DNA level ,blood platelet count(BPC) ,coagulation function ,model for end-stage liver disease(MELD)score and mortality at 24 weeks were analyzed .Furthermore ,comparison of the clinical data between the survival patients and died patients in superinfection group was made .Unconditioned binary response logistic regression model was used to determine the corresponding risk factors .Results The level of total bilirubin(TBIL) ,MELD score ,incidence rate of hepatic encephalopathy and mortality at 24 weeks were signifi-cantly higher and prothrombin activity(PTA)was significantly lower in superinfection patients(P<0 .05) .The level of serum creat-inine(Cr) ,MELD score and incidence rate of hepatic encephalopathy were significantly higher and PTA was significantly lower in died patients than that of superinfection group(P< 0 .05) .Logistic regression analysis identified TBIL(P= 0 .024 ,OR= 1 .006) , BPC(P=0 .019 ,OR=0 .983) ,PTA(P=0 .001 ,OR=0 .795) ,MELD score(P=0 .005 ,OR=1 .497)and hepatic encephalopathy(P=0 .001 ,OR=4 .147)as prognostic factors for patients with superinfection of HEV and HBV related ACLF .Conclusion The clini-cal features of patients with superinfection of HEV and HBV related ACLF were more serious .The higher level of TBIL ,MELD score and hepatic encephalopathy and the lower level of BPC and PTA ,the worse prognosis .

SUN Shu-chun,the chief researcher,is one of the famous expert of osteo-traumatology of TCM.He makes systematic sort and study on chirismus on basis of succeeding experience predecessors and his own years of clinic experience.He is good at treating cervical syndrome with TCM chirismus,especially combine it with drugs.In osteo-traumatology academic circles,he is called "the best doctor at home".Professor SUN advocates that the rule of applying various therapies according to different conditions,combination of rigid-flexible,light,skill,gentle,harmony should be obey when we use chirismus.His diagnostic and therapeutic methods and thoughts are original and ingenious.In this article,the author analyzes the academic experience of tendon trauma of professor SUN.

OBJECTIVETo study the efficacy of Xiaoyao Powder (XYP) combined with interferon alpha (IFN-alpha) in treating HBeAg positive chronic hepatitis B (CHB) patients and the effect on their quality of life (QOL).

METHODSTotally 193 patients with HBeAg-positive CHB confirmed by liver biopsy were randomly assigned to 2 groups, Group A (94 cases) and Group B (99 cases). IFN-alpha1b was subcutaneously injected to patients in Group A at the dose of 50 microg, thrice per week. Those in Group B additionally took XYP. The therapeutic course for all was 24 weeks. Clinical efficacy was observed by assessing ALT restoration rate, HBeAg negative rate, HBeAg conversion rate, HBV DNA negative rate, complete response rate, partial response rate, and symptoms integral. The evaluation of QOL was performed by using chronic liver disease questionnaire (CLDQ) score. Adverse reaction occurrence rate was observed in the two groups.

RESULTSBetter effects were obtained in Group A on ALT restoration rate, HBeAg negative rate, HBV DNA negative rate, complete response rate, partial response rate, TCM symptoms integral, the total effective rate of TCM sysmptoms, CLDQ score, and adverse reaction rates, showing statistical difference when compared with Group B (P < 0.05, P < 0.01).

CONCLUSIONXYP could elevate the efficacy of TCM symptoms of HBeAg-positive CHB patients and anti-viral effect, improve their QOL, and reduce adverse reaction of IFN-alpha.

Objective:Establish mass-scale purification technology of cell-derived influenza virus. Methods: A microcarrier-based process was used to produce human influenza virus in serum free-adapted Vero cells. The virus was purified in a sequence of downstream processing steps including inactivation, clarification, anion exchange chromatography, affinity chromatography and size-exclusion chromatography. Results: The recovery of HA reached 102%. 95.3% total protein, including 99.77% host cell protein, and 99.99% host cell DNA were removed during downstream processing. Conclusion: Providing a high effective purification technology for cell-derived influenza virus.
