1.0 ?10 7 copies/ml than those with lower HBV DNA levels both in combination group and lamivudine group (52.0% vs 25.8%, P= 0.04; 63.2% vs 28.6%, P= 0.03). Necro-inflammatory activity, fibrosis and the expression of HBV DNA showed no correlation with response rate in combination group. Among those who had higher levels of HBV DNA expression, seroconversion rate in combination group is higher than that in lamivudine group (46.2% vs 9.5%, P= 0.03). Conclusions The efficacy of combination therapy appeared to be better in patients with at least moderately elevated baseline ALT, high level of HBV DNA as well as HBV DNA expression in hepatocytes. Combination therapy may delay or diminish the development of YMDD mutation-related resistance to lamivudine.

Hepatitis B virus (HBV)-related liver failure has an extremely high mortality rate and a complex pathogenesis,and since related mechanisms are not fully understood,it has been very difficult to diagnose and treat this disease in clinical practice.Apart from liver transplantation,there is still a lack of specific and effective drugs and therapies for the medical treatment of HBV-related liver failure.This article summarizes our experience and research achievements in the diagnosis and treatment of HBV-related liver failure,explores the association between host's genetic background and development and aggravation of chronic hepatitis B,and elaborates on the phenomenon of three attacks and the concept of four time phases.In the aspect of treatment,this article focuses on the clinical application of antiviral therapy,anti-infective therapy,glucocorticoids,and stem cell transplantation;for the evaluation of patients' condition,this article establishes a suitable system for evaluating the prognosis of HBV-related liver failure.

Objective To investigate the effect of cryotherapy of employing Argon/Helium assisted with TACE for the unresectable primary liver carcinoma. Methods 124 cases with primary liver carcinoma were randomly divided into two groups:60 cases were treated by TACE and cryotherapy; the other 64 cases were simply done by TACE as control. In general, TACE was undertaken once a month and altogether three times for a course. Cryotherapy was undergone 1-3 times for a course. Results The total effective rates (CR+PR) were 45.3% for the control group and 68.3% for the combined therapy group, with an obvious difference between the two groups, 0.5,1,1.5 years survival rate were 81.3%,62.5%,43.8% respectively in the control group;93.3%,83.3%,63.3% respectively for the combined group. There was an obvious difference between the two groups of 1,1.5 years of survival rates. Conclusions Cryotherapy of employing Argon/Helium assisted with TACE for the unresectable primary liver carcinoma is feasible with raising the effective rate and prolonging survival time.

Liver failure caused by hepatitis B virus (HBV) infection is common in China, among which acute-on-chronic liver failure (ACLF) is the main type.Because the pathogenesis is complex and the diagnosis and treatment is difficult,HBV related ACLF has high mortality.In recent years, some progress has achieved in diagnosis and therapy of ACLF.This article reviews the new strategies and advances about HBV related ACLF on basis of researches at home and abroad,including the definition, mechanisms, management and prognosis assessment of ACLF.

0.05).Conclusions The expression of galetin-3 was obviously increased in liver metastasis from colon cancer,and MCP can effectively inhibit the development of liver metastasis of colon cancer.

Objective To analyze the clinical characteristics of children with cyclic vomiting syndrome (CVS), summarize the clinical experience, and improve the awareness,diagnosis and treatment level of CVS.Methods The clinical data and results of long-term follow-up of the children with CVS were collected and analyzed from 1995 to 2009 in our department.Results Forty-six children were enrolled in the study, including 22 boys and 24 girls.Mean onset age was 4.5 years(ranged from 1 to 11 years)and the mean age at final diagnosis was 8.5 years (ranged from 4.5 to 14.5 years).Sixty-six and seventy-four percent of patients had family history of migraine and motional sickness respectively,whereas 83% patients had triggers.The clinical manifestation of CVS was severe episodic vomiting.The episodes had a rapid onset and sudden ending,persisted for several hours to days,and were separated by symptom-free intervals.The incidental symptoms were pallor, lethargy,intractable nausea,abdominal pain,headache,photophobia and dizzy.Twenty-nine patients diagnosed were followed up for 5 years at average.Five patients were treated with valproate,4 with cyproheptadine, 5 with cyproheptadine and valproate,5 with amitriptyline,cyprohep tadine and valproate,and 3 with cyproheptadine and flunarizine.All treated patients recovered mean 10 months(1.5 months to 2 years) years later and displayed the reduced number of episodes or the severity of episodes except 3 patients.Twenty-eight percent (8/29) of patients progressed to migraine headaches.Conclusion CVS is a relatively common disease in children and awareness of the condition should be increased.CVS should be considered when patients had recurrent vomitting and were completely healthy between the two episodes after excluding other pathological conditions.

Objective To appraise the postoperative anti-reflux function of vertical esophagogastic valve-plasty anastomosis for cardiac cancer.Methods Forty patients with cardiac cancer were randomly divided into study group and surgery control group,with 20 patients in each group.The study group underwent vertical esopagogastric valve-plasty anastomosis,while the surgery control group underwent conventional esophagogastrostomy.Ten healthy volunteers were recruited as normal control group.A 24-hour esophageal pH monitoring and endoscopy check-up was carried out in all experimental subjects at 90 days postoperatively.Results All of the pH monitoring indexes in study and surgery control groups were higher than those in normal control group(P

Background and purpose:Hyperthermia could directly kill cancer cells or induce apoptosis,it has also been proved to improve immunity of patients.In this study,we evaluated the efficacy and side effects of hyperthermia combined with transcatheter arterial infusion chemotherapy in the treatment of intermediate and advanced non-small cell lung cancer(NSCLC).Methods:Forty patients with intermediate and advanced non-small cell lung cancer were randomly divided into two groups,with 20 each.Group A was treated with transcatheter arterial infusion chemotherapy in combination with hyperthermia,Group B was treated with interventional arterial infusion chemotherapy alone.Treatment response in both groups were evaluated as well as side effects after one or two cycles.Results:As to Group A,Karnofsky score had been improved in 16 cases,accounting for 80%(16/20);compared with 50%(10/20)in the Group B,there was significant difference(P

AIM: To study signal transduction pathway of nitric oxide-induced PC12 cell death. METHODS: After PC12 cells were incubated with sodium nitroprusside(SNP), caspase-3 inhibitor Ⅱ plus SNP or p38 inhibitor-SB203580 plus SNP, cell survival rate was quantified by MTT assay and caspase-3 activity was measured with caspase-3 assay kits. RESULTS: SNP induced PC12 cell death in a dose- and time-dependent manner, and increased caspase-3 activity gradually. Both caspase-3 inhibitorⅡand SB203580 reduced cell death significantly, but SB203580 reduced caspase-3 activity significantly. CONCLUSION: NO might induce PC12 cell death through the activation of p38 and caspase-3.
