Objective To recognize normal sinus rhythm (NSR), ventricular tachycardia (VT) and ventricular fibrillation (VF) from each other accurately and promptly. Methods A nonlinear descriptor based on multi-scale analysis, Hurst index, as a feature to quantify the nonlinear dynamics behavior of the ECG signal, was quoted in this paper. Results The nonlinear technique, Hurst index was examined and evaluated with ECG signals extracted from MIT-BIH Arrhythmia Database, MIT-BIH Malignant Ventricular Ectopy Database, and CU Ventricular Tachyarrhythmia Database under a specific moving-window length. The experiment showed good performance of this nonlinear descriptor. When the window length was 5 s long, the recognition accuracy for each of NSR, VT and VF was 100%. Besides, the computing speed was much faster than the speed obtained with a traditional non-linear technique, the complexity measure algorithm. Conclusion The Hurst index has a strong potential for life-threatening ventricular arrhythmia recognition in clinical applications.

Kawasaki disease is an acute self-limiting systemic vasculitis syndrome and usually occurs in children.The small and medium arteries of the whole body are mainly invaded, and marked with coronary arteries.Coronary artery dilation and aneurysm formation mainly occur in the early period.Thrombi, intimal hyperplasia, and calcification could be formed during the later period.Consequently, sometimes, it develops intochronicischemic cardiopathy or myocardial infarction.In that, Kawasaki disease has become the leading cause of acquired heart disease for children in developed countries.Presently, the treatment of coronary artery lesions caused by Kawasaki disease includes drug therapy, and interventional and surgical treatment.However, medications usually fail to solve severe coronary conditions, and only interventional and surgical treatment can we choose.Therefore, the development and indications of interventional and surgical treatment of coronary artery lesions caused by Kawasaki disease were reviewed in this article.

The main factor is the number of patients, which predicted by least square method to reduce the deviation. The like equipments located nearby are also considered and the Shared Coefficient is proposed.

To treat 30 patients with simple adiposis with needling of point Jiaji (Ex-B2, T3-L5), after 2 courses of treatment 12 got a marked curative effect, 15 got a curative effect, 3 got no effect, accounting for 10.0%. The total effective rate was 90.0%.

Objective To evaluate the clinical efficacy of atorvastatin combined with salvianolate in treatment of chronic obstructive pulmonary disease (COPD) complicated with pulmonary arterial hypertension (PH) , and its influence on hypoxia inducible factor-1 alpha (HIF-1α), endothelin-1 (ET-1), adrenomedullin (ADM) in serum.Methods 30 cases of COPD patients with PH were randomly divided into 2 groups, each of 15 cases.The two groups were given conventional treatment, including rest, continuous low flow oxygen, anti infection, relieving cough and phlegm, relaxing tracheal, correcting water and electrolyte balance.Control group was received Atorvastatin Calcium Tablets 20 mg orally, once daily.Observation group was received Atorvastatin Calcium Tablets 20 mg once daily, once daily;salvianolic 200 mg+0.9% sodium chloride solution 250 mL, intravenous drip, once daily.The course of treatment was 10 d.Before and after treatment, 6 min walking distance(6 MWD) and hemodynamic parameters were detected, including pulmonary artery systolic blood pressure (PASP), cardiac output (CO), right ventricular end diastolic pressure (RVEDP) , and HIF-1, ET-1 and ADM level in serum.Results After treatment, 6MWD, PASP, CO, RVEDP of the two groups were significantly improved compared with the same group before treatment.But compared with control group, observation group was improved significantly, the difference was statistically significant (P<0.05).After treatment, HIF-1 alpha, ET-1 of the two groups were significantly lower than the same group before treatment, but ADM were significantly increaser( P <0.05 ) .Compared with control group, HIF-1 alpha, ET-1 of observation group were significantly decreased, while the ADM was significantly increased, the difference was statistically significant (P<0.05).Conclusion Atorvastatin combined with salvia miltiorrhiza polyphenols can significantly reduce the pulmonary artery pressure in patients with COPD and PH, increase exercise tolerance, and its mechanism maybe related to the regulation of the expressions of HIF-1, ET-1 and ADM.

OBJECTIVE:To study the protection of XNSK on renal ischemical reperfusion injury model rats.METHODS:A total of60rats were randomized into sham operation group(without occlusion of renal arteries of both kidneys and admin?istered with0.1%dimethyl sulfoxide normal saline),control group(0.1%dimethyl sulfoxide normal saline),positive control group(administered with Shenfukang capsules)and XNSK(high,medium and low dose subgroups)group.Levels of serum creatinine(Scr),urea nitrogen(BUN)and malonaldehyde(MDA)in renal tissue,hemocuprein(SOD),active oxygen(ROS)and nitrogen monoxidum(NO)were determined respectively meanwhile the pathomorphology changes of tissues were observed.RESULTS:As compared with the control group,levels of Scr,BUN,MDA,ROS and NO in all the3(high,medium and low doses)XNSK subgroups(which were administered with drugs for7days before operation and undergone reperfusion once after operation)had a reduction while SOD level had an increase.And there was a mitigated pathomorphology change in nephridial tissues(P

Objective To explore predictive factors of early-onset complications in children with acute bacterial meningitis.Method Retrospective study was made on clinical data and predictive factors of early-onset complications of 75 children with acute bacterial meningitis who were treated in our hospital during 2000-2005.Results The incidence of early-onset complications in children with acute bacterial meningitis was 50.7%,subdural effusions and hydrocephalus occured freqiently.The incidence of early-onset complications were closely correlated with onset age,coma,seizure,cerebrospinal fluid(CSF) protein concentration and CSF glucose concentration.Onset age younger than 12 months(OR=11.876,95% CI:2.592-54.33 P
