The pharmacological therapy of cardiac arrhythmias is still challenging. As is well known, antiarrhythmic drugs have a narrow therapeutic-toxic window and can induce lethal proarrhythmia (antiarrhythmic drug-induced arrhythmia). The harmful effect of antiarrhythmic drug was proven by CAST and so many clinical trials. Thus we need strict indications for prescription and objective parameters for monitoring of the drug action and side effects. The cardiac arrhythmias are classified as ectopic beats, bradyarrhythmia, and tachyarrhythmia. The main target of antiarrhythmic drugs is tachyarrhythmia. The clinical role of antiarrhythmic drugs is the acute conversion of arrhythmia to sinus rhythm and the chronic suppression/prevention of tachycardia. The cardiac arrhythmia (arrhythmogenesis) occurs in harmony of 3 components, namely, substrate, precipitating (modulating) factors, and trigger. The acute modification of arrhythmogenic environment by drug may be efficient, but the chronic suppression of arrhythmia only by the drug may not be complete. Recently, the clinical role of chronic drug therapy is replaced by RFCA (in patients with SVT except atrial fibrillation) and ICD (VT/SCD). The antiarrhythmic drugs are usually classified into Class I (sodium channel blocker), Class II (beta-blocker), Class III (potassium channel blocker), Class IV (calcium channel blocker), and others (digoxin and adenosine), according to Vaughn-Williams suggestion. Nowadays, the clinical electrophysiologist reclassified the agents into calcium channel-dependent drug (Class II, IV, digoxin, and adenosine) and sodium/potassium channel-dependent drug (Class I and III). The drug is effective only when the concentration in blood or tissue is sufficient to modify the arrhythmogenic substrate. We need to know the pharmacokinetic and pharmacodynamic properties of antiarrhythmic drugs exactly. We can expect the blood concentration of a drug if we know the elimination half-life and the dosing schedule of the drug because most drugs (including antiarrhythmic agents) have the first-order (elimination) kinetic. For a new steady-state of drug concentration, we should wait for 3 to 4 times of the half-life after changing the dosage (prescription). Finally, the consideration and management of the underlying heart disease and precipitating/modulating factors are needed for the effective antiarrhythmic drug therapy.

Objective To evaluate the impact of hypertension self-management on self efficacy of community residents.Methods November 2011 to February 2012,twenty-eight medium-sized and better adherence to community was selected from fourteen districts and counties in Beijing.In this community-based randomized controlled trial,323 hypertensive patients were randomly assigned to the treatment group (n =159,receiving hypertension self-management) and the control group (n=164,receiving standard hypertension management).A questionary survey was completed at baseline and 6 weeks.Rank sum test or Chi-square test was used for data analysis.Results The average age of the treatment group or the control group was (61.9 ±9.1) vs (61.8 ±9.0) years old,respectively.No significant difference in mean age,gender and education level was found between the two groups (F =0.164,x2 values were 0.782 and 2.093,respectively ; all P ＞ 0.05).In the treatment group,the scores of fatigue,headache and shortness of breath were declined (when compared with the controlled females,Z =-5.198,-3.873,-2.781 ; P ＜ 0.05).Self-efficacy score of the treatment group was increased after the intervention.Women's symptom management self-efficacy and common disease management self-efficacy were significantly higher (Z=-2.958,-2.582; P ＜ 0.05).In comparison with the control group,before and after self-management,the added scores of communication ability with doctors were increased.But the difference was not statistically significant (P ＞ 0.05).Conclusion Six-week self-management program may improve self efficacy among hypertensive patients.

Objective To analyse the therapeutic effect of Carvedilol in patients with severe heart failure.Methods The clinical data of 89 Carvedilol patients treated with dilated cardiomyopathy were retrospective analysis.Results The overall therapeutic effective rate was 98.88％,because of one death related to discontinued use of medication.Before and after treatment,systolic left ventricular cavity diameter (LVDD) were (68.25 ± 2.15) mm,(56.89 ±4.21) mm,respectively,and left ventricular ejection fraction(LVEF) were (28.63 ±0.33)％,(40.56 ±3.98) ％,respectively,there were significantly differences (t =7.215,16.877,all P ＜ 0.05).Conclusion Carvedilol is the cornerstone in the drug treatments of patients with dilated cardiomyopathy.

Diabetes complicated with urinary tract infection is influenced by many factors, such as low immune function, high blood and urine glucose environment prone for bacterial growth, and nervous lesion.Diabetic urinary tract infections are characterized by insidious onset, high recurrence rate, correlation with high blood glucose and difficulty to control.The related bacterial pathogens are mainly gram-negative bacillus genus ( 58. 59%-76. 19%) , in which the detection rates of extended spectrum β lactamases( ESBLs) Escherichia coli and Klebsiella pneumonia were the highest, followed by Enterobacter cloacae. Gram-positive bacteria only accounted for 23%. Drug-resistant bacteria and fungi would increase under the condition of repeated infection and irrational usage of antibiotics.In recent years, the urine-derived sepsis caused by urinary tract infection had become a popular clinical research topic because of its concealed symptoms, acute onset, rapid development and high mortality. By reviewing domestic and foreign literatures and expert consensus, this article is intended to explore the characteristics and treatment of diabetic urinary tract infections to supply reference for early prevention, correct diagnosis and effective treatments.
