Use somatostatin after PD can restrain organism excrete diastase vera,and help anastomotic stoma to concrescent and decrease pancreatic leakage;pancreatic leakage should be treated by different grades,grade 1 can be cured by persistent drainage with somatostatin and nutritional support;grade 2 should be pay more energetic intervention.

PD后应用生长抑素持续泵入可以抑制胰酶的作用，使胰肠吻合口较好地愈合，从而有效地减少胰漏的发生；胰漏可进行分级治疗，Ⅰ级胰漏采用通畅引流为主，同时使用生长抑素和营养支持等治疗多可治愈，Ⅱ级胰漏需要积极治疗。

objective:to investigate the therapeutic action of somatostatin in pancreatic leakage after pancreaticoduodenectomy.methods: to collect 100 patients with pancreaticoduodenectomy during 2003～2006,contrast 44 patients use somatostatin after pancreaticoduodenectomy as experimental group,and 56 patients with conventional therapy as control group.results:there were no pancreatic leakage case in the modified group of 44 cases.3 cases complicating pancreatic leakage occurd in control group,and the proportion of pancreatic leakage are different examined by statistic mathord.conclusions:use somatostatin after pd can restrain organism excrete diastase vera,and help anastomotic stoma to concrescent and decrease pancreatic leakage;pancreatic leakage should be treated by different grades,grade 1 can be cured by persistent drainage with somatostatin and nutritional support;grade 2 should be pay more energetic intervention.

Pancreatin is a mixture of various enzymes that is extracted from pancreas of pig, cow, sheep, etc.. It is one of the important products of our country in bio-chemical medicine industry.

胰酶是从猪、牛、羊等胰脏中提取的多种酶的混合物，是我国生化制药行业的重要产品之一。

The influence of the addition of chitosan, the pH, and the temperature was evaluated. And the properties of pancreatin separating with flocculation were compared with pancreatin separating with acetone.

探讨了壳聚糖用量、pH值、温度等因素对絮凝作用的影响，并比较了絮凝胰酶和丙酮胰酶性质的差异。

In this study, the optimum conditions of the pancreas extracted pancreatin from porcine blood and utilization of the pancreatin to hydrolyze the porcine blood protein were studied.

研究了猪新鲜胰脏提取胰酶以及胰酶粗提液降解猪血蛋白获取蛋白水解液的条件。

Then, the specific activities of protease and amylase were relatively lower than pancreatin separating with acetone, but the specific activity of lipase was higher. The ratio of activities in filtrate were very low, showing the precipitation was effective.

其中蛋白酶和淀粉酶的活力较低，与丙酮胰酶(3159U/g和58.7kU/g)相比有较大的差距，但是脂肪酶活力较高，高于丙酮胰酶的50.10kU/g。

But pancreatin is a mixtrure of various enzymes, each enzyme has a low purity and many enzymes have similar molecule structure and physicochemical properties, when extracting one enzyme, it is easy to abandon the otherone as impurity. This is why there are few technoloies of stimutaneous extraction of more than three enzyme from pancreatin and all the technoloies have shortages.

但是由于胰酶为多种酶的混合物，每种酶的纯度很低，许多酶又具有相似的分子结构和理化性质，因此往往在提取一种酶的同时，其它酶被当作杂质处理掉了，这就导致了胰酶中三种以上酶联产的工艺极为少见，而且已有工艺都有各自的不足。

Combizym, an agent of double-deck pellet containing Oryz-Aspergillus enzyme and pancreatin, has been used in patients with dyspepsia for decades in Western countries. However, there is not yet any data of the efficacy and safety of this agent in China.

背景：米曲菌胰酶片是含有米曲菌酶和胰酶的口服双层包膜复合消化酶制剂，在国外用于治疗消化不良已有数十年，然而目前国内尚无米曲菌胰酶片治疗消化不良症状疗效和安全性的资料。

In aqueous solution no binding observed in crystal structure. In cyclohexane, one amylamine molecule is observed in the active site of trypsin and more sulfates are also found on enzyme surface, which are further proofs that electrostatic interaction are stronger in organic solvent.

在水溶液中，晶体结构难以观察到戊胺与牛胰酶的结合，在环己烷中，一个戊胺分子结合在胰酶的活性中心，同样酶表面观察到了更多的硫酸根，这些都进一步验证了有机溶剂中静电相互作用加强。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
