Objective To observe the change of sinus heart rate turbulence (HRT) and its relation to left ventricular systolic function (LVSF) in patients with acute coronary syndrome (ACS). Methods The 103 ACS patients and 62 healthy subjects were enrolled in this study, all of them received 24-hour Holter monitor. And the values of turbulence onset (TO), turbulence slope (TS)and heart rate variability (HRV) SDNN were calculated according the Holter records. The clinical information, left ventricular ejection fraction (LVEF) and left ventricular end diastolic diameter (LVEDD) were recorded. Then the ACS patients were divided into acute myocardial infarction (AMI)group and unable angina pectoris (UAP) group according to the cardiac enzymes and electrocardiogram. Results The value of TO was significantly higher in ACS group than in control group [(0.17±1.40)％ vs. (- 0.26±0.99)％, P＜0.05], and TS was significantly lower in ACS group than in control group [R-R interval:(0.88±2.51) ms vs. (2.60±2.76) ms, P＜0.01].There were significant differences in TS, LVEF and LVEDD between AMI group and UAP group (all P＜0.01), but there were no differences in HRV and TO between the two groups. TS was positively correlated with LVEF (r=0.21, P＜0.05), while TO was negatively correlated with LVEF (r=-0.26, P＜0.05) by Spearman correlation analysis. Conclusions HRT is significantly blunted in ACS patients and can evaluate cardiac autonomic function. It may be as a predictor of LVSF in ACS patients.

Objective:To investigate the effects of IL-18BP blockade on apoptosis of synovial cell in IL-18 induced Collagen-induced-arthritis(CIA) in mice and its possible mechanism.Methods: CIA mice were established by freund′s complete adjuvant,and divided into 5 groups:normal group,CIA model group,IL-18-CIA group,MTX group and IL-18BP group,each for 10,total 50 mice.The expression of Fas and FasL in the synovial tissue of the left posterior ankle joint taken from each group were detected by immunohistochemistry analysis.Results: IL-18BP group compared with the model group,the mice of joint swelling was inhibited,the expression level of Fas and FasL increased significantly,the difference was statistically significant (P<0.01);IL-18BP group has a significant curative effect and basically recovered to normal level(P<0.05).Conclusion: IL-18BP can promote the apoptosis of synoviocytes by regulating the expression of apoptosis genes Fas and FasL,which is helpful for the treatment of rheumatoid arthritis.

Objective To investigate the clinic characteristics and treatment methods of coronary ectasia. Methods One hundred and fifty-four cases in Anzhen hospital during the last 10 years, whom with coronary aneurysm diagnosed by coronary artery angiogram and summarized the characteristics of symptom, sign, diagnosis and treatment. Results All patients were proved with coronary angiography. There were 112(72.7%)patients presenting angina, but with no specific manifestation in electrocardiogram, X-ray and echocardiogram.Thrombolysis in emergency were taken to 3 cases with acute myocardial infarction patients. One hundred and fifty-four cases were treated with aspirin or heparinizeation, and with nitroglycerin, Calcium channel blocker to dilate vessel. The followed up of 154 cases about 1-20 years, six cases were suffered with acute myocardial infarction. One of the 6 cases was reinfarction and one case was sudden death. Conclusions Angina is the main clinical manifestation and coronary angiography is the accurate diagnostic method. Long-term application with anticoagulant agent and vasodilator should be done to prevent coronary spasm and myocardial infarction. If acute myocardial infarction occurs, prompt thrombolysis should be used, if it is ineffective, coronary artery bypass grafting should be carried out.

Objective To assess the prevalence, and characteristics, and in-hospital and long-term prognosis of coronary artery disease (CAD) with metabolic syndrome, and to determine the factors affecting the prognosis of CAD most. Method The DESIRE (drug-eluting stent impact on revascularization) registry covered a database of 2368 patients with coronary artery disease (CAD) treated with percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG) in a period between July 2003 and September 2004. The median long-term follow-up time was 3.5 years ranged from 293 to 1855 days. The metabolic syndrome (MS) was diagnosed on the Definition of the Metabolic Syndrome modified by the Adult Treatment Panel (ATP) Ⅲ in 2005, by using the body mass index (BMI) instead of waist circumference. The relationship between metabolic syndrome (MS) and the incidences of major adverse cardiac as well as cerebral events (MACCE) in a large cohort of patients treated for revascularization was analyzed by using logistic analysis and Cox regression with SPSS 11.0 software. Results The Ms was present in 45.6% patients (high fast glucose (FG) in 44.5% patients, high triglycerides (TG) in 45.0% patients, low high density lipoprotein (HDL) in 50.8% patients, high BP in 61.4% patients, high BMI in60.7% patients). After follow-up, the ratio of MACCE in CAD patients with metabolic syndrome increased significantly (18.9% vs. 15.6%, P <0.036). The most dangerous factors of MS were high FG, hypertension and obesity (OR=1.787, 95%CI=1.132-2.845, P =0.014). Conclusions The MS contributes the high risk factors of MACCE in CAD patients with or without diabetes. The most dangerous combination of risk factors in MS is the combination of high FG, hypertension and obesity.

Objective To evaluate the prognosis of drug-during stent (DES) implantation in elderly patients versus non-elderly patients, and to determine the clinical outcome of complete revascularization strategy versus incomplete revascularization strategy in elderly patients. Methods Patients who were treated with at least 1 DES in our hospital were enrolled in the study. They were divided into 3 groups: the elderly group (aged 75～89 years), the presenium group (age 60～74years) and the non-elderly group (aged 40～59 years). The patients aged 60～89 years were further divided into complete revascularization group and incomplete revascularization group according the Percutaneous interventional the rapy (PCI) strategy. Clinical characteristics, angiographical and interventional data were collected. Results The success rate of PCI procedure was 99.3% in elderly group(n=137), 98.7% in presenium group(n= 1006), and 99.3% in non-elderly group(n= 1031).There were no significant differences among the three groups(P>0.05). The in-hospital mortality was highest in the elderly group among the three groups (1.5%, 0.4%, 0.1%, P<0.05), but the in-hospital rates of re-infarction, repeated revascularization and stroke had no significant differences among the three groups (P>0.05). During follow-up, the rates of death and stroke were highest in the elderly group(3.1%, 2.3%, 0.7%, P<0. 01;1.5% , 1.3%, 0.3%, P<0.05, respectively),but the rates of re-infarction and repeated revascularization among the three groups had no significant differences (all P>0.05). By Cox regression analysis, serum creatinine (OR= 2.961,95%CI=1. 643～5.338,P<0.01), gender (OR=2.661,95%C1=1.376～5.145 ,P<0.01), age(OR=2.687,95%CI=1.329～5.434, P<0.01), multi-vessel disease(OR= 1.735,95 %CI= 1.132～2.661, P<0.05), and old myocardial infarction (OR = 2.041 ; 95% CI = 1.026～4.061; P<0.05) were the independent predictors for all-cause death in patients aged 60～74 years. The in-hospital mortality was higher in the incomplete revascularization group than in complete revascularization group in patients aged 60～74 years (1.4% vs. 0.2%, P<0.05). Multiple logistic regression analysis revealed that the incomplete revascularization strategy was not the independent predictor of in-hospital death (OR=0.307; 95%CI=0.011～8.467; P>0.05). Conclusions Although DES implanting is successfully procedured in presenium and elderly patients, it is associated with higher in-hospital mortality, especially in patients aged ≥75 years . Presenium and elderly patients are to be more benefit from complete revascularization strategy, but the incomplete revascularization strategy does not influence the long-term outcomes.

Objective To study the effect of citicoline on mild cognitive impairment MCI) in pa tients with middle cerebral artery stenosis (MCAS).Methods Eighty-six MCAS patients with MCI were divided into citicoline group (n=44) and control group (n=42).The patients in citicoline group were treated with citicoline (0.2 g,3 times a day) for 6 months on the basis of conventional treatment.Cerebrovascular reserve,PI,BHI and Vm between the two groups were compared by transcranial Doppler ultrasonography after treatment.MCI between the two groups was assessed according to the MoCA after treatment.Results The rate of cerebrovascular reserve,PI,BHI and Vm were significantly higher in citicoline group than in control group (13.59％± 1.16％ vs 7.61％±1.12％,P＜0.01;0.51±0.16 vs 0.58±0.12,P＜0.05;1.36±0.08 vs 0.74±0.11,P＜ 0.01;32.63％ ±2.32％ vs 16.92％ ± 1.68％,P＜0.05).The total MoCA score,attention,language,visuospatial and executive function,abstract,naming,orientation and memory were significantly higher in citicoline group than in control group (P＜0.01).Conclusion Early citicoline treatment can improve cerebrovascular reserve and alleviate MCI in MCAS patients.
