Heart failure is a syndrom of heart disease with high morbidity and mortality .There are more and more evidence indicating immune activation developing important role in the occurrence and development of heart failure . Interleukin (IL)‐35 ,known as a negative regulatory factor of one of the members of IL‐12 family ,participates pathogenetic process of heart failure .The present article made a review for influence of IL‐35 on heart failure .

Objective To summarize and discuss the diagnostic and treating experiences of chronic pancreatitis with mass in the head. Methods Eight patients of chronic pancreatitis with mass in the head who were misdiagnosised as carcinoma of head of pancreas were analyzed retrospectively in the past 10 years. Results All the patients exhibited abdominal pain,5 of whom were with jaundice and 3 with anorexia. All the patients were misdiagnosised as carcinoma of head of pancreas before the operation,but the pathology after operation indicated chronic pancreatitis. The pancreaticoduodenectomy was performed in 5 patients,the choledochojejunostomy in 2 patients,while the exploratory laparotomy in 1 patient. After the operations,the abdominal pain was relieved in 7 patients, while 2 patients who accepted pancreatoduodenectomy suffered from pancreatic fistula,1 of whom died in the end. Conclusion It’s hard to differentiate the chronic pancreatitis with mass in the head from the carcinoma of head of pancreas before operation. If the carcinoma of head of pancreas can’t be excluded during the operation,the pancreatoduodenectomy should be performed,while the duodenum-preserving total resection of the head of the pancreas or any intra-drainage operations should be done if chronic inflammation is found in the whole pancreas with a negative result of the biopsy of the pancreas through the needle aspiration.

Objective To investigate the Th1/Th2 polarization of T lymphocytes in human peripheral blood stimulated by CpG-ODN2216,and the secretion of cytokines in supernatant of cultured PBMCs after stimulation of CpG-ODN2216.Methods Human PBMCs were isolated from blood of donors.The PBMCs were incubated with CpG-ODN2216 for 24 hours.Th1/Th2 subsets in the cultured PBMCs were examined by flow cytometry,and IFN-?,IL-2,IL-4 and IL-10 in the supernatant were assayed by ELISA.Results The percentage of Th1 and Tc1 increased significantly after stimulation of CpG-ODN2216 compared with control group (P0.05).Conclusion The Th1 cells and Tc1 cells in T lymphocytes of peripheral blood could be polarizated by CpG-ODN 2216.IFN-? secretion in PBMCs could be induced by CpG-ODN2216.

AIM:To examine and compare the effects of several ARBs that are widely used in clinics , on the ACE-Ang II-AT1 receptor and the ACE2-Ang(1-7)-Mas axis during the development of cardiac remodeling after pressure overload .METHODS: All of the mice used in the study underwent transverse aortic constriction (TAC) or sham operation for 2 or 4 weeks.A solution of either ARBs or sa-line was administered through a stomach tube 3 days before the operation .Meanwhile , to eliminate the influence of Ang II , a recombi-nant adenovirus expressing small interfering RNAs targeting angiotensinogen ( Ad-ATG siRNA) was injected via the tail vein .The sur-gery was then performed and the drug was administered as mentioned above .Cardiac function and remodeling were evaluated by echo-cardiography , hemodynamic measurements and cardiac histology .Western blotting was used to determine the protein expression levels . Meanwhile , we performed similar experiments using ARBs with or without ATG siRNA in cardiomyocytes induced by mechanical stretch.RESULTS:Although all of the six ARBs , none of which repressed the elevation of left ventricular pressure after TAC , attenu-ated the development of cardiac hypertrophy and heart failure in the wild-type mice, the degree of attenuation by Olmesartan , Candesar-tan and Losartan tended to be larger than that of the other three drugs tested .Additionally , the degree of downregulation of the ACE-Ang II-AT1 axis and upregulation of the ACE2-Ang(1-7)-Mas axis was higher in response to Olmesartan, Candesartan and Losartan administration in vivo and in vitro.Additionally, Olmesartan had a larger influence when administered long term .However, the expres-sion of ACE was not influenced by the administration of ARBs in vivo and in vitro.Moreover, in angiotensinogen-knockdown mice, TAC-induced cardiac hypertrophy and heart failure were inhibited by Olmesartan , Candesartan and Losartan but not by Telmisartan , Valsartan and Irbesartan administration .Furthermore , only Olmesartan and Candesartan could downregulate the ACE-Ang II-AT1 axis and upregulate the ACE2-Ang(1-7)-Mas axis in vitro.CONCLUSION: Olmesartan, Candesartan and Losartan could effectively in-hibit pressure overload-induced cardiac remodeling even when with knockdown of Ang II , possibly through upregulation of the expres-sion of the ACE2-Ang(1-7)-Mas axis and downregulation of the expression of the ACE-Ang II-AT1 axis.In contrast, Telmisartan, Valsartan and Irbesartan only played a role in the presence of Ang II , and Losartan had no effect in the presence of Ang II in vitro.

Objective To evaluate the safety,biocompatibility and efficacy of transcatheter closure of atrial septal defect(ASD)with no stainless-steel-screw occluder in canine model.Methods The device was constructed from superelastic Nitinol wires tightly woven into two flat disks and sewed with polyester fibers inside,with a pliable loop on the right-atrial-disk of the device,connecting to the delivery cable.ASD was created by transcatheter puncture and balloon dilatation and then closed by occluder under fluoroscopy in the catheterization laboratory.The location and the influence of the implanted device on function of tricuspid valve and mitral valve were evaluated by echocardiography.At 1,2,3 and 6 months after the operation,the animals were killed and autopsy was conducted.Results Eight dogs with puncture-produced ASD underwent ASD closing procedure successfully.The occluder showed no influence on the function of MV and AV demonstrated by echocardiogram.The two disks of the implanted device were covered with a smooth intact neogenesis layer in all dogs.Endocardial cells fully covered the surface of the two disk without inflammating reaction 3 months later. There was no evidence of corrosion on the surface of the nitinol wire removed from the dog after 6 months.Light microscopic examination of the liver,kidney,lung and spleen showed no evidence of embolization and inflammation.Conclusion Transcatheter ASD occlusion with new-type occluder is safe,feasible,effective and good biocompatibility with a good prospective clinical application.

Objective To study prognosis of patients with fulminant hepatitis after plasma ex- change treatment using model for end-stage liver disease(MELD)scoring system.Methods 160 pa- tients were randomly divided into plasma exchange group and control group,and MELD score was calculated according to the original formula for each patient.The efficacy of plasma exchange was as- sessed by mortality and improvement in biochemical parameters and MELD score.Results The levels of total bilirubin(TBIL),INR and MELD score of patients whose MELD scores were between 30 and 40[TBIL,(379.4?40.4)?mol/L; INR,2.5?0.2; MELD,30.8?3.8]were lower than before PE treatment[TBIL,(509.7?64.6)?mol/L;INR,3.5?0.3;MELD,37.3?3.5].The levels of TBIL and INR and MELD score of patients whose MELD scores were higher than 40 [TBIL,(595.6?61.5)?mol/L;INR,3.8?0.4;MELD,39.8?3.5]were lower than before PE treatmem [TBIL, (650.4?66.3)?mol/L;INR,4.4?0.6;MELD,45.2?4.2].The mortality of patients in PE group with MELD score from 30 and 40 was 50.0%,while it was 86.7% in control group,showing significant differ- ence between PE group and control group(P＜0.01).The mortality of patients with MELD scores higher than 40 was 91.2% in PE group and 100% in control group,showing no significant difference between these two groups(P＞0.05).Conclusions Plasma exchange treatment can decrease the serum TBIL level, INR and MELD score of patients with fulminant hepatitis and improve liver function.Compared with the control group,plasma exchange can significantly decrease the mortality of patients in PE group with MELD score from 30 to 40,but no effect on patients with MELD score higher than 40.

Objective To discuss the significance of the application of real-time quantitative PCR(RQ PCR)for diagnosis and guidance therapy of cytomegalovirus(CMV)infection after allo- hematopoietic stem cell transplantation(allo-HSCT).Methods Thirty-three patients were undergo- ing allo-HSCT.After hematopoietic reconstitution,patients'peripheral blood samples were detected for CMV DNA by RQ-PCR periodically.Anti-viral therapy was begun,attenuated and stopped ac- cording to the results of CMV DNA detection.The effects of anti-viral therapy and patients' clinical results were observed.Results CMV DNA was detected in blood samples from 13 of 33 patients. There were 21 episodes in these patients.Only 1 episode wasn't controlled hecause the patient gave up the therapy.CMV DNA copies were disappeared soon or decreased and then disappeared during anti-viral therapy in the others'.Patients which had symptoms and/or dysfunction of organs were cured too.Each course of anti-viral therapy was shorter than ordinary course.Conclusions CMV in- fection can he diagnosed as early as possible by RQ PCR.To begin,attenuate and stop anti-viral ther- apy according to the results of RQ-PCR is safe.The course is shortened and the side effects of anti vi- ral drugs were attenuated.

Objective To evaluate the clinical efficacy of lamivudine in preventing liver injury induced by anti-tuberculosis drugs in hepatitis B virus(HBV)carriers.Methods One hundred and ten HBV carriers treated with anti-tuberculosis drugs were randomly divided into lamivudine group and control group.Patients in both groups were treated with conventional anti-tuberculosis drugs (isoniazid,rifampicin,pyrazinamide,streptomycin or ethambutol)for 6-8 months.However, patients in lamivudine group were treated with lamivudine 100 mg orally dairy concomitantly.Before and after treatment,the clinical manifestation,liver function and serum HBV DNA level of patients were evaluated.Statistical analysis was performed using t test and x~2 test.Results During 6-8 months of treatment,the incidence rate of liver injury was 9.1% in lamivudine group,while it was 38.2% in control group(P0.05).Conclusion Lamivudine is effective and safe in reducing liver injury induced by anti-tuberculosis drugs in HBV carriers.
