We reported 261 cases of patients with acute myocardial infarction (AMI) definitely diagnosed in our hospital from 1992 to 1997.Thirty eight cases of them were found pericardial effusion.This indicated that the pericardial effusions in AMI incidence rate was 14.5%.It related to the Q wave infarction and heart failure.The percardial effusion was common and benign.I was complication in the AMI.

Objective To observe the therapeutic efficacy and action mechanism of muscle-region alignment electroacupuncture in treating post-stroke shoulder pain. Method Eighty patients were randomized into a muscle-region alignment needling group and a conventional acupuncture group. The Short-form McGill Pain Questionnaire (SF-MPQ), and serum levels of IL-6, TNF-?, and NO were majorly observed before and after the treatment. Result The muscle-region alignment electroacupuncture and conventional acupuncture both obviously reduced the SF-MPQ score and down-regulated the serum levels of IL-6, TNF-?, and NO, and the decreases by the muscle-region alignment electroacupuncture were more significant than that by the conventional acupuncture. Conclusion The action of muscle-region alignment electroacupuncture in treating post-stroke shoulder pain is plausibly by down-regulating serum levels of IL-6, TNF-?, and NO, reducing or inhibiting the production of inflammatory factors and restraining inflammation.

Objective To investigate the clinical and radiological features of the patients with cryptogenic stroke as the first manifestation of pulmonary arteriovenous malformation (PAVM),and to explore the mechanism and summarize the diagnostic strategy.Methods Transcmnial Doppler (TCD) bubble tests,non-contrast or contrast-enhanced transthoracic and transesophageal echocardiography,contrast-enhanced thoracic CT and pulmonary angiography were performed in 2 patients with cryptogenic stroke for the detection of right to left shunt (RLS) and the diagnosis of PAVM.Then interventional catheter embolization of PAVM and postoperative follow-up were arranged.Results TCD bubble tests in these 2 patients showed the following characteristics indicating RLS:spontaneous continuous shunt at rest,earlystage shunt appeared rapidly after injection,considerable large amount of shunt volume as a shower of microbubble,the extent of shunt volume not attenuated by Valsalva Maneuver (VM).One patient was diagnosed as PAVM,the other was PAVM plus patent foramen ovale (PFO).Both patients of PAVM were successfully treated with interventional catheter embolizations.Then TCD bubble test was repeated and showed significantly decreased amount of RLS.They remained asymptomatic during the 3-year and 1-year follow-up.Conclusions In patients with cryptogenic stroke due to suspected paradoxical embolism,TCD bubble test should be performed for screening RLS.Besides PFO,a traditional access to intracardiac shunt,PAVM should be considered as a new access to extracardiac shunt in paradoxical embolism.
