Based on the theory of tidal flow and sediment motion, a 2-D depth-integrated mathematical model for the Jiaojiang Estuary is developed by using explicit scheme of finite difference on the triangle elements. The results show that the rotary currents occurring in this area can be simply and effectively simulated by the model. Meanwhile, the suspended sediment concentration simulated is in agreement with the field data.

本文根据椒江口实测水文地形资料，从平面二维水流泥沙基本方程和基本理论出发，采用三角单元有限差分法对水流泥沙方程显示求解，对椒江口潮流泥沙进行了数值模拟，模型简单实用，较好地再现了具有旋转潮波性质的椒江河口水流运动特征，含沙量场也得到了基本正确的反映。

Methods: From May 1985 to December 2002, 2240esophageal and stomach cardia cancer patients treated by intrathoracic esophagogastric "layer-to-layer"anastomosis with esophageal mucosa extended varied in plane were retrospectively analyzed.

回顾性总结1985年5月～2002年12月共进行胸腔内食管黏膜延长不同平面与胃、食管分层吻合术2240例，统计手术后和出院后随访资料发生吻合口瘘和吻合口狭窄的情况。

To evaluate the clinical value of intrathoracic esophagogastric "layer-to-layer" anas tomosis with esophageal mucosa extended varied in plane and to study the effective methods to prevent anastomotic leaking or stricture postoperatively.

目的 评价胸内食管黏膜延长不同平面与胃、食管分层吻合术，探讨预防食管吻合口瘘和吻合口狭窄发生的吻合方法。

Intrathoracic esophagogastric "layer-to-layer" anastomosis with esophageal mucosal extended varied in plane is an ef fective method to prevent anastomotic leaking and stricture postoperatively.

食管、胃黏膜延长不同平面分层吻合术是预防吻合口瘘和吻合口狭窄的有效吻合方法。

Abstract］ Objective To discuss the influencing factors of healing up of anastomosis between traditional and morden ideas and question the more reasonable method of intestinal tract preparation in stage one operation.Methods Twenty-six patients with colon cancer were divided into 3 groups:colostomy group（8 cases）,washing group (9 cases) and suction group (9 cases).All the patients underwent colectomy plus stage one anastomosis and exteriorization with different interoperative preparation with which we compared the healing up of anastomosis within the three groups.

目的 探讨影响吻合口愈合因素的传统与现代观念并进步探讨一期手术中合理的肠道准备方式方法 26例降结肠癌分为造瘘组（8例）、冲洗组（9例）和粪便吸引组（9例）三组，术中分别采用3 不同方式行紧急肠道准备，所有病人均采用结肠切除一期吻合加外置的方法，对比观察三组病人的吻合口愈合情况。

Patients accepted the operation, one patient underwent in site fascicle repair,parastomal hernia reoccured 10 M after the operation,13 patients were been cured between 10 M to 3 years after the operation.

结果： 14例结肠造口手术至出现造口旁疝时间6～38个月，平均20个月，均予手术治疗，其中1例行原位筋膜修补术，术后10个月复发，13例随访10个月～3年，均无复发。

In the operation, the place of the external mouth of abscess was designed, the skin was cut along inter muscular septum between the sphincter internus and the sphincter externus, the subcntaneous tissues were separated along the lateral clearance of the sphincter internus to the pelvirectal fossa, then the internal mouth of abscess was cut. The vomica was leaved to idle after being scraped fully, and the pus was drained perennially with fenestrated tube.

采用设计外口的位置，沿内、外括约肌间沟入路，切开皮肤，分离皮下组织，顺内括约肌外侧间隙分离至骨盆直肠窝，切除内口，并将脓腔充分搔刮后旷置，腔内放置有孔胶管持续引流，结合术后祛腐消肿止痛期及活血止痛生肌期的药物换药，旨在提高对骨盆直肠窝脓肿的一次根治率和保护肛门功能，减少并发症发生。
