Objective To investigate effects of emergent percutaneous coronary intervention(EPCI)on the prognosis of patients with cardiac arrest(CA)and cardiopulmonary resuscitation after acute myocardial infarction(AMI).Methods Thirty-two patients with CA and carcliopulmonary resuscitation after AMI were retrospectively reviewed and divided into EPCI group(n=12)and eonservative treatment group(n=20).EPCI was used during or after primary eardiopulmonary resuscitation in EPCI group but not in conservative treatment group.Mortality and occurrence rates of severe arrhythmia,of heart failure,of cardiac shock and of severe bleeding in hospital were compared between the two groups.Results The mortality in hospital was 17% in EPCI group and 70% in conservative treatment group,respectively(P＜0.001).Heart failure was developed in 3 patients from EPCI group and 16 patients from conservative treatment group,respectively(P＜0.01).There was no significant difference in severe arrhythmia,cardiac shock and severe bleeding between two groups(P＞0.05).Logistic regression showed that EPCI decreased mortality but the prolonged cardiopulmonary resuscitation(＞20 min)increased the mortality.Conclusion Early EPCI might improve the prognosis of patients with cardiac arrest and cardiopulmonary resuscitation after acute myocardial infarction.

The data collected from 34 type 2 diabetic patients receiving intensive insulin therapy for six years showed that the yearly mean HbA1C was less than 7.0％,and none of the patients showed severe hypoglycemia,occurrence or evident progression of retinopathy or nephropathy,and the islet β cell function gained improvement.The DQOL score,used to evaluate the quality of patients' life had no significant change during the observation ( P ＞0.05 ).It is satisfactory and safe to maintain long-term glycemic control with prolonged intensive insulin therapy in patients with type 2 diabetes,and that such therapy does not induce untoward influence on the quality of diabetic patients life.

Objective To evaluate the safety and efficacy of percutaneous transluminal angioplasty (PTA) in treating Budd-Chiari syndrome (BCS) and to analyze the long-term follow-up results. Methods From October 1998 to May 2008,98 BCS patients (inferior vena cava obstruction,n = 34 ; hepatic vein obstruction, n = 22; combined obstruction, n = 42) who accepted PTA treatment successfully were investigated. The changes of clinical manifestations and liver function post-operation were observed; the long term survival rate was evaluated. Results Only two patients were complicated with transhepatic puncture tract bleeding, the prognosis was good after emergency operation. Sixty patients presented with low extremities edema, which was fully subsided after PTA.Of eighty-eight ascites patients, ascites disappeared in eighty patients after operation, and in the other eight patients combined with oral diuretic treatment post-operation. The median Rotterdam prognostic score of one month post-operation and the last follow-up time point was 0. 11 and 0. 09, significantly lowered than pre-operation (1.12). The difference was statistical significance (P=0. 000). At 1, 3, 5 years postoperative, the cumulative vessel patency rates were 96%, 94% and 94% respectively, and the cumulative survival rates were 94%, 91% and 87%. Conclusions Treating BCS with PTA has a high success rate, a good safety and a long-term survival rate.
