Interferon (IFN) is one of the commonly used anti-HBV drug in clinic,in which IFN-λ is a new type of IFN,including IFN-λ1,IFN-λ2 and IFN-λ3 (also called IL-29,IL-28A and IL-28B,respectively).Researches in recent years show that IFN-λ3 (IL-28B) polymorphism seems to be involved in the onset of hepatitis B,the response to antiviral therapy and the outcome of HBV infection.This paper reviews the correlations between IL-28B polymorphism and the spontaneous clearance of HBV,the progression of HBV infection,the occurrence of liver cancer and the therapeutic effect of IFN treatment.

Objective To study the effect of comprehensive care on the level of high-sensitivity Creactive protein and matrix metaloproteinase-9 in patients with hemorrhagic infarction.Methods 48 patients with hemorrhagic infarction were divided into the control group and the observation group with 24cases in each group.The control group was given conventional care,the observation group was given comprehensive care.Serum hsCRP and MMP-9 level of all patients were measured on day 1,day 3,day 7,day 14.Results The level of serum hsCRP and MMP-9 in the observation group on day 7 was significantly decreased compared with on day 1.The level of serum hsCRP and MMP-9 in the observation group on day 7 was lower than the control group.On day 14,the level of serum hsCRP and MMP-9 returned to normal in the observation group,which was lower than the control group.Conluusions The implementation of comprehensive care for HI patients can effectively reduce the hsCRP and MMP-9 level in serum,shorten hospitalization time,and is conducive to the prognosis of patients.

Objective: To analyze the risk factors affecting prognosis of calciifc aortic stenosis in patients elder than 75 years of age and to compare the safety among different treatments. Methods: A total of 421 consecutive aortic stenosispatients treated in our hospital from 2008-01-01 to 2015-01-01 were retrospectively studied. The patients were at the age of (79.1 ± 3.5) years and with 243 (57.7%) of male gender. According to echocardiography data, the patients were divided into 3 groups: Mild stenosis group,n=112, Moderate stenosis group,n=83 and Severe stenosis group,n=226. All patients were followed-up for 1 year to observe the end point of all cause and cardiac death. In Severe stenosis group, mortalities by different treatments were compared; the risk factors related to death were calculated by Logistic regression analysis. Results: The overall 1 year all cause and cardiac mortalities were 22.3% (94/421) and 19.7% (83/421) respectively, both all cause and cardiac mortalities were similar among 3 groups,P>0.05. Multivariate Logistic regression analysis indicated that peripheral vascular disease (OR=2.31, 95% CI 1.215-4.392), LVEF (OR=0.966, 95% CI 0.942-0.991) and NT-proBNP (OR=2.022, 95% CI 1.140-3.586) were the independent risk factors for 1 year all cause death; diabetes (OR=2.157, 95% CI 1.213-3.836), LVEF (OR=0.975, 95% CI 0.950-1.000), NT-proBNP (OR=2.786, 95% CI 1.449-5.356) and blood levels of phosphorus (OR=5.755, 95% CI 1.462-22.657) were the independent risk factors for 1 year cardiac death. In Severe stenosis group, the all cause mortalities by medication, PBAV, TAVR and SAVR were 43.6%, 57.1%, 7.3% and 6.45% respectively, the patients with TAVR, SAVR had the lower mortality than those with medication, P<0.0001, while the mortality was similar between the patients with TAVR and SAVR, P>0.05. Conclusion: All cause and cardiac mortalities within 1 year were increasing with the age accordingly, while aortic stenosis grade was not related to mortality in elder patients with calcific aortic stenosis. Peripheral vascular disease and blood levels of phosphorus were the risk factors affecting prognosis. TAVR and SAVR had better effect for treating the patients with severe aortic stenosis.

Objective This study aimed to describe the sex disparities on cancer incidence and mortality in Jiashan population.Methods All data concerning incident and death cases of cancers were gathered from the database of Cancer Registry in Jiashan county.Data from the 2010 China census was used as the standard population.Sex-specific age-standardized incidence rates (ASIRs),mortality rates (ASMRs) per 100 000 persons for all cancers and types of each cancer were calculated for the years of 1990 to 1999,2000 to 2009,2010 to 2014,and 1990 to 2014.In addition,the corresponding male-to-female incidence rate ratios (IRRs) and mortality rate ratios (MRRs) were also calculated.Results The ASIR of all cancers was 226.13/105 for the whole period of 1990 to 2014,with 266.04/105 for males and 187.22/105 for females,respectivcly.The corresponding IRR was 1.42 (95％CI:1.39-1.46),with significant difference noticed in the incidence rates between males and females (P＜0.05).The ASMR of all cancers was 155.39/105,with 206.55/105 for males and 104.98/105 for females,respectively.The corresponding MRR was 1.97 (95％ CI:1.91-2.03),with significant difference between males and females (P＜0.05).Among all the cancer types,only gallbladder cancer and thyroid cancer showed female predominance in both incidence and mortality,with male predominance in all the remaining cancers.Conclusion Finding from our study suggested that a male predominance in both incidence and mortality for a majority of cancers in Jiashan population.

Objective: To compare the outcome of surgical high-risk elderly patients with severe aortic stenosis(SAS) treated by different therapy procedures, including transcatheter aortic valve implantation(TAVI), surgical aortic valve replacement(SAVR), and drug therapy. Methods: We retrospectively analyzed the clinical data of 242 surgical high-risk elderly (age ≥65 years old) SAS patients hospitalized in Fuwai Hospital between September 2012 and June 2015. According to the treatment method, patients were divided into TAVI group (81 cases), SAVR group (59 cases) and drug therapy group (102 cases). The primary end point was all-cause mortality at 1 year post procedure, and secondary end point included cardiac function class(NYHA), vascular complication, valvular function, non-fatal myocardial infarction, new atrial fibrillation, stroke, bleeding, pacemaker implantation, acute renal failure, and readmission. We used the Kaplan-Meier method to estimate survival function based on follow up data and survival was compared between groups with the use of the log-rank test. Results: (1) In the baseline data, there were statistically significant difference among 3 groups for the age, left ventricular ejection fraction, cardiac function class Ⅲ and Ⅳ, rates of combined diabetes, chronic renal failure, mild and moderate mitral regurgitation (P<0.01 or 0.05). The risk score of the Society of Thoracic Surgeons(STS) was 7.28±4.98 in the TAVI group, and 5.67±3.49 in the SAVR group(P=0.036). (2) The perioperative rates of pacemaker implantation(11.3%(9/81) vs. 0, P=0.025) and mild paravalvular regurgitation(29.6%(24/81) vs.1.7%(1/59), P<0.001) were significantly higher in TAVI group than in SAVR group.(3)The rate of rehospitalization was significantly lower in TAVI group than in SAVR group(3.0%(2/67) vs. 22.7%(10/44) P=0.005) and the rate of pacemaker implantation was significantly higher in TAVI group than in SAVR group(17.5 (12/67) vs. 0, P=0.008) after 1 year. The rates of death from any cause in the TAVI (5.8%(4/67)) and SAVR group (11.4%(5/44)) were significantly lower than that in the drug therapy group (54.9%(50/91), both P<0.05) after 1 year and was similar between TAVI group and SAVR group(P=0.622). (4) The rates of cardiac function classⅠandⅡ increased and Ⅲ and Ⅳ decreased in TAVI and SAVR group after 1 year when compared with base line(P<0.001). The rates of cardiac function class Ⅱ, and Ⅲ increased , class Ⅰ and Ⅳ decreased in drug therapy group after 1 year compared with base line (P=0.020). (5)The survival rates after 1 year were significantly higher in the TAVI group and SAVR group than in the drug therapy group(log-rank test, P<0.001), and the difference was similar between TAVI group and SAVR group (log-rank test, P=0.062). Conclusion In surgical high-risk elderly patients with SAS, the prognosis of drug therapy was poor, and TAVI and SAVR were associated with similarly improved rates of survival after 1 year, although there were significant differences in periprocedural complications between TAVI and SAVR groups.

Aortic stenosis is a valve disease characterized by dynamic and continuous changes in structure and function of left ventricle.Left ventricular remodeling,which embodies pathological changes in myocardial cellular and ventricular geometry,is an important prognostic factor of patients with aortic stenosis.Aortic valve replacement is the only effective treatment for severe aortic stenosis.Current guideline recommendations for interventions are based on symptoms and left ventricular ejection fraction.With the improvements of modern imaging technology,different patterns of remodeling,including hypertrophy and fibrosis,could be identified now.Studies also explored the close association between left ventricular remodeling and function in the setting of aortic stenosis.In this review,we aim to elucidate the characteristic imaging features and potential mechanisms of left ventricular remodeling,and further,we highlight the clinical value of specific imaging features and clinical application of modern imaging methods in the evaluation,risk stratification,and intervention decision-making for patients with aortic stenosis.
