Kawasaki disease (KD) is an acute febrile systemic vasculitis,and the cause of KD is not well understood.Based on epidemiologic studies and surveys,several features of KD strongly suggest a genetic component to disease pathogenesis.As a result of their involvement in immune response,human leucocyte antigen (HLA) genes have been extensively studied in association with outcomes of autoimmune and infectious diseases.HLA gene polymorphisms have also been reported to be associated with KD.Now,HLA gene polymorphisms related to KD is focused.

Kawasaki disease (KD) is a systemic vascular inflammatory lesion in children with acute febrile rash illness. The inci-dence rate in recent years is increasing. The traditional treatment in some patients is ineffective, and KD has high incidence of cardiovas-cular complications. Therefore, the selection of an appropriate therapy for KD is an urgent. With the continuous advance of biomedical and pharmacologically research, many biological agents were developed. The traditional treatment has been gradually replaced by the new biological agents which achieved the desired results. Thus this paper reviewed several common biological agents in the clinical treatment of KD.

Mammalian target of rapamycin(mTOR) inhibitors have the anti-tumor ettect,which have been known early.The traditional mTOR inhibitors include rapamycin and its derivatives,which have been applied in clinical use early.Nowadays,some new small molecule inhibitors such as the PI3K/mTOR duel inhibitor,Torinl,one after another are found to play a unique role in the tumor therapy.

Recent studies have found that autophagy was not only involved both in the occurrence and development of viral myocarditis (VMC),but also,it plays a key role in anti-viral infections by degradating the viral components,presenting viral antigens and activating the immune response.Meanwhile,the virus can also escape the protective antiviral activity and maintain their own survival and replication by inducing the autophagy of the host cells,becoming the accelerator of the viral infection.The interaction of the virus and the host cell autophagy in VMC is a complex process.Its detailed pathogenesis has yet to be further explored.

To investigate the association between HbA1C level and severity of coronary artery lesion in non-diabetic patients with coronary heart disease. This study was a retrospective and controlled study in a single center. 302 patients were enrolled. Coronary arterial lesion was confirmed by coronary angiography carried out in Tianjin Chest Hospital between January 2008 and November 2011. The patients enrolled should be non-diabetic with normal fasting blood glucose and HbA1C levels. The patients were divided into 3 groups according to the HbA1C levels, Group 1 (≤5. 5%, n=92),Group 2(5. 6%-5. 8%, n=94),Group 3(5. 9%-6. 4%, n=116), and the SYNTAX scores between the groups were compared. The predictive value of HbA1C in groups with intermediate and high SYNTAX score was identified by Logistic regression analysis while common risk factors such as sex, age, hypertension, lipid, and fasting glucose were adjusted. The SYNTAX score from Group 1 to Group 3 had statistically significantdifference(P<0.01). Simpleregressionwasusedtocalculatethecorrelationcoefficient(r=0.335,P<0. 01). Binary Logistic regression was used to confirm that HbA1C level was also associated with intermediate and high SYNTAX score(OR=5. 089, P<0. 05). In non-diabetic patients, the HbA1C level is associated with the severity of the lesion of coronary artery. The results indicate that a higher level of HbA1C seems to be an independent predictor to the prevalence of complex coronary lesions.

Objective To compare two different revascularization methods in type 2 diabetes mellitus (T2DM) patients with multivessel coronary artery disease treated by percutaneous coronary intervention (PCI) and coronary artery bypass graft ( CABG) .Methods T2DM patients with multivessel disease undergoing success-ful PCI or CABG were enrolled in the study .They were diagnosed by coronary angiography ( CAG) in Tianjin Chest Hospital from May 2009 to May 2010 whose.The patients were followed up for 3 years.The information of patients including physical performance , clinical features , and laboratory examination results were collected .The major ad-verse cardio cerebral events(MACCE)including death, myocardial infarction(MI), revascularization, angina pecto-ris, heart failure, and stroke were collected.Results During the 3 years of follow-up, MACCE(31.58% vs 17.68%, P<0.01), death(4.82%vs 1.10%, P<0.05), MI(4.39%vs 1.10%, P<0.05), angina pectoris (17.27%vs 10.50%, P<0.05)occurred more frequently in PCI group than in CABG group .Conclusion Evi-dences now tend to support CABG for revascularization in T 2DM patients with multivessel disease .

Objective To evaluate the effcets of tirofihan on myocardial no-reflow after acute myocardial infarction and reperfusion by delayed enhancement-multi-slice CT(DE-MSCT).Methods Chinese mini pigs were randomized into control group and firofiban treatment group. Acute myocardial infarction was induced by balloon occlusion of the medium segment of the left anterior descending artery for 90 minutes. Repeffusion was created by withdrawing the balloon during angiography. All successful models received DE-MSCT examinatons at 1 h, 24 h, 48 h, and 72 h after reperfusion to observe the myocardial noreflow area. Data were analyzed with Spearman rank correlation and Wilcoxon Rank Sum test. Results Six pigs were successfully induced as acute reperfusion myocardial infarction in each group. Furthermore,4 pigs in control group and 3 pigs in firofiban treatment group had no-reflow phenomenon. The no-reflow volume percent increased from 1 h to 72 h in both groups. The no-reflow volume percent was significantly reduced in tirofiban treatment group compared with control group after reperfusion at 1 h, 24 h, 48 h and 72 h respectively[(4.78±0.66)% and (9.62±3.05)%, t =6.000, P＜0.05; (5.84 ± 1.19)% and (13.44±3.33)% ,t=6.000,P＜0. 05;(6.41± 1.24)% and (15.10±3.76)%,t =6.000,P ＜0.05;(6.63 ±0. 82)% and (15.94 ±4.62)% ,t =6.000,P ＜0.05] ,as well as the infarct myocardium volume percent was significantly reduced in tirofiban treatment group compared with control group at 24 h, 48 h and 72 h after reperfusion [ (19.74± 2. 94) % and ( 25.08 ± 4.68) %, t = 25.000, P ＜ 0.05;(20.34±2.46) % and (27.07 ±5.44)%, t =26. 000,P ＜0.05; (20.72 ±2.10)% and (26.17 ±5.19)% ,t = 24.000,P ＜0.05]. Conclusions DE-MSCT can be used to detect the extent of no-reflow phenomenon. Tirofiban can reduce the volume of myocardial infarct and no-reflow area after reperfusion.

Objective To assess the long-term effects of pacing in patients with hypertrophic obstructive eardiomyopathy(HOCM),and explore the most specific echocardiographic indexes.MethodsA total of 37 consecutive HOCM patients implanted dual-chamber pacemakers were enrolled and followed up.Thirty-seven cases were followed up for 1 year,26 cases were followed up for 2 years,and 10 cases were followed up for 3 years.After 1,2 and 3 years pacemaker implantation,pacing frequency,pacing threshold,impedance,atrioventricular delay and cumulative percent atrial and ventricular pacing were respectively tested,and left atrial dimension (LAD),left ventricular end-diastolic dimension (LVEDd),left ventricular posterior wall thickness (LVPW),interventricular septum thickness (IVS),left ventricular outflow tract diameter(LVOTd),left ventricular outflow tract pressure gradient (LVOTPG),left ventricular ejection fraction(LVEF),pulmonary artery systolic pressure (PASP) were measured and mitral valve systolic anterior motion(SAM) was observed.Pacing parameters and echocardiography indexes were dynamically compared before and after pacemaker implantation.ResultsPacing frequency was adjusted 60～70 bpm,atrioventricular delay was adjusted 90～ 180 ms,in order to achieve more than 95％ ventricular pacing,pacing threshold,pacing impedance were normal.The difference of various pacing parameters were no statistically significant within 3 years ( P ＞ 0.05).Compared with before pacing,after 1,2 and 3 years pacemaker implantation,IVS and LVOTPG declined significantly (P ＜ 0.01 ),LVOTd widened significantly ( P ＜0.01),SAM phenomenon improved obviously ( P ＜0.01 ),but the difference of LAD,LVEDd,LVPW,LVEF,PASP were no statistically significant ( P ＞ 0.05 ).Conclusions The heart structure reconstruction of patients with HOCM can been chronically improved by dual-chamber pacing treatment.IVS,LVOTd and LVOTPG can be used as the sensitive and specific indexes to evaluate pacing treatment.

Objective To observe the effect of different doses of atorvastatin combined with probucol on contrast induced acute kidney injury (CIAKI) and serum uric acid in elderly patients.Methods Totally 121 cases admitted for coronary angioplasty were randomly divided into three groups.In standard combining treatment group (n＝35),atorvastatin 20 mg qn and probucol 0.25 g,tid were given with no loading dose intake before angioplasty.In intensively combined treatment group (n＝41),atorvastatin 40mg qn and probucol 0.25 g,tid were given with a loading dose of atorvastatin 40 mg and probucol 0.5 g at 2 hours before angioplasty.In intensive atorvastatin therapy group(n＝45),atorvastatin 40 mg qn were given,with a loading dose of atorvastatin 40 mg 2 hours before angioplasty.All patients were then evaluated 24 hours before and after angioplasty procedure,and their blood urea nitrogen (BUN),serum creatinine (Scr),serum uric acid (SUA),estimated glomerular filtration rate (eGFR) by modified diet in renal disease study (MDRD) method were tested.The serum and urine at 24 hours before and after operation were collected.Neutrophil gelatinase associated lipocalin (NGAL) were determinated by enzyme linked immunosorbnent assay (ELISA) method.Results After operation,eGFR was decreased in standard combining treatment group [(76.2±14.3) ml· min-1 · 1.73 m-2 vs.(71.9±17.9) ml· min-1 · 1.73 m-2,P＜0.05],while Scr,eGFR and uNGAL showed no changes in intensively combining treatment group and intensive atorvastatin therapy group (P＞0.05) ; BUN in the two groups was decreased [(5.6± 1.4)mmol/L vs.(4.7±0.9) mmol/L,(5.3±1.2) mmol/L vs.(4.8±1.2) mmol/L,P＜0.01,P＜0.05].SUA was reduced in intensively combining treatment group (P ＜ 0.05).uNGAL was increased in standard combining treatment group (P ＜ 0.05).Conclusions For elderly patients,intensive atorvastatin therapy and combining intensive treatment can both improve CIAKI.Only combination and intensive treatment benefit for decrease of uric acid.
