依赖传统的损失分布理论，财产损失分布模型拟合的优劣往往取决于经验分布函数的选择和参数的确定。

using the returns variance minimum of hedging as objective function,using positive profit skenewss as constraint of serious loss'probability,the constraints of hedger serious loss optimal model is set up.

摘 要：以套期保值收益率的最小方差为目标函数，以收益率偏度大于等于零控制套保者遭受重大损失发生的概率，建立了基于重大损失控制的套期保值优化模型。

Loss of visual function, but also the loss inherent in the shape of the eyeball.

Methods: Between November 2003 and December 2005, 67 patients with renal cell carcinoma underwent retroperitoneal laparoscopic radical nephrectomy (34 patients, group A) and open radical nephrectomy (33 patients, group B). Operating time, blond loss, amount of postoperative drainage, time to ambulation, recovery of intestinal function after operation, the postoperative hospital stay, use of antalgesic and transfusion blood and plasma were compared between group A and group B, retrospectively. Results: In group A, the operations of 31 patients were successful and 3 cases failed, then conversed to open surgery. Firstly, one case were not decented the prerenal fascia and the other two cases occurred complications, one case was due to injurying genital gland vein, with blood loss of 500m1, another fatty renal capsula was too thick to explose the renal pedicle. The operations of group B were all successful, only one case was died of intracerebral hemorrhage after two monthes.

回顾性分析和比较后腹腔镜肾癌根治性切除术(Retroperitoneal laparoscopic radical nephrectomy， RLRN)34例与开放性肾癌根治性切除术(Open radical nephrectomy， ORN)33例，比较两种方法的手术时间、术中出血、术后引流、术后最早下床活动时间、肠功能恢复情况、术后住院时间、术后镇痛剂使用量、术中术后输血、血浆量、术后随访时间及手术效果结果：A组中1例因最初对解剖结构难于辨认，无法分离肾前筋膜至肾门而改行开放手术，1例因损伤精索静脉出血难以控制而改行开放手术，1例因肾周脂肪过多，无法将肾脏掀起显露肾蒂而行开放手术，31例手术成功。B组手术均获成功，1例术后2个月因大面积脑出血死亡，余均无瘤生存。

The support of TPN at least for 7 days in gastric cancer patients with significant weight loss and severe malnutrition going to receiving operation maintained the nutritional status and prevented continuous weight loss. The early enteral feeding through jejunostomy tended to increase serum hemoglobin, hematocrit, and iron levels to prevent deterioration from anemia. Additionally, nutritional support gradually improved the immune function of gastric cancer patients by increasing total lymphocyte counts.

对於准备要接受胃癌手术体重明显减轻的严重营养不良病患，给予七天以上的全静脉营养支持，可维持病患之营养状况且避免体重持续减轻；术后透过空肠造口给予早期肠道营养支持，对於血清中的血色素与血比容和铁质有助上升趋势，避免贫血情况恶化；由总淋巴球数的增加发现营养支持可以渐渐恢复病患之免疫功能。

The main work of the paper is shown as follows.1 The optimal model of the single and combinatorial hedging based on the constraints of total loss is established.The paper takes the positive profit skenewss as constraint of serious loss\' probability, which the tail of curved shape on density function of the hedging yield elongates right,and the left tail become short.

论文的主要工作如下：(1)建立了基于整体风险控制的单品种和多品种的套期保值优化模型通过套期保值收益率的偏度大于等于零，使得套期保值收益率密度函数的尾部向右拉长，而左端的尾部较短。
