Results One case with transverse mesocolon pore hernia, one with obturator hernia and one with paracecal hernia were confirmed by exploratory laparotomy. There were six cases whose hernias resulted from the fall of export jejuna into import jejuna after Billroth II anastomoses in front of colons, five from the pelvic bottoms' peritoneal fissure and four from the fissure appearing between descending colon and lateral abdominal wall after Miles' operation, one from greater omental adhesion to sigmoidal wall after sigmoidostomy, and one from inflammatory adhesion on the basis of Meckel's diverticulum. The other 17 cases' hernias (48.7%) were caused by the fissure among celiac adhesive bands, peritonea, celiac organs, enteric walls and intestines.

Methods 203 cleft palate patients(406 ears)were investigated by pure tone audiometry,acoustic immitance audiometry and auditory brainstem response.21 cleft palate patients with SOM underwent palatoplasty and myringotomy with tube insertion at the same time.

方法对 2 0 3(4 0 6耳)例腭裂患者进行年龄分组，采用声导抗，纯音测听或听性脑干反应检查判断中耳功能。2 1例腭裂伴分泌性中耳炎患者在作腭裂修复术的同时，行鼓室置管术，术前术后作听力学检测。

Background— The effect of prearrest left ventricular ejection fraction on outcome after cardiac arrest is unknown.

背景——停跳前的左室射血分数对心脏骤停预后的影响尚未明了。

Conclusions— Moderate and severe prearrest left ventricular systolic dysfunction was associated with substantially lower rates of survival to hospital discharge compared with normal or nearly normal function.

结论——与正常或接近正常心功能相比，停跳前中和重度左室收缩功能障碍与显著低下的出院时生存率有关。

Methods: The transesophageal atrial pacing and electrophysiologic study were performed in 237 patients with history of tachycardia, if PSVT was induced, the patients received overdrive suppression or program prestimulation.

选择237例有心动过速发作史的患者进行食管心房调搏检查，如果诱发出阵发性室上速，进行12导联心电图记录后，予以短阵快速刺激或程序期前刺激终止之。
