Pericardiocentesis is a fast, safe, accurate and popular choice under the guideline of flouroscopy and contrast medium.

一旦明确诊断，积极穿刺引流是首选的治疗方法。X线透视与造影剂指示下心包穿刺引流是一种快速、安全、准确、值得推广的方法。

But being different from the others, drainage of the peripancreatic infection after the occurrence of SPI is very difficult, which needs many times of operation. Especially, the infection can be a vicious cycle, in which the systemic septicemia can be caused by localized infection or vice versa.

实际上，许多疾病的发生、发展和预后均与肠源性感染密切相关，但是SPI的特殊性在于发生感染后难以进行有效的手术引流、常常需要多次手术和多次置管引流，而且全身性败血症和局部感染交替出现，成为恶性循环。

The nucleotide sequences of the PAP gene and PAPⅡ gene in the root of Phytolacca americana were determined by reverse transcription polymerase chain reaction and PCR. The gene comprises 942bp and 933bp respectively, encoding 313 amino acids and 310 amino acids. When PAP gene and PAPⅡ gene sequences in the root were compared with those in the spring leaves and summer ones, the highest similarity 100% and 99. 8% were observed respectively. They both had one open reading frame . Analysis of the two sequences showed, in fact, they belonged to one species.

以美洲商陆根为材料，提取其总RNA、反转录，用一对PAP基因的特异性引物和一对PAPⅡ的特异性引物，分别对反转录产物进行PCR扩增，将扩增的目的片段进行序列分析，结果扩增出来的PAP基因与已经报道的序列完全相同，扩增出来的PAPⅡ基因与已经报道的序列同源性也在99.8％，而且它们都各自编码一个开放阅读框架，可以说美洲商陆根中肯定存在PAP和PAPⅡ基因，并已经转录。

Fucata as well as Pteria penguin were studied using RAPD markers in order to develop interspecific marker for species identification;(2) inheritance of AFLP markers in families of Pinctada fucata were investigated using AFLP markers, based on which a draft genetic map was constructed.

其中引物S10对7种珍珠贝的RAPD产物呈现出物种的特异性，可同时将7种珍珠贝分开，其余引物可以将2种或2种以上的珍珠贝区别开来。

Irrigation and drainage through presacral double-cavity tube and operation were used in patients respectively.

对吻合口漏的患者采用手术及保守治疗（骶前双腔管冲洗引流加肛管引流）。

Irrigation and drainage through presacral double-cavity tube is a simple, safe and less suffering method to treat anastomotic leakage after anus-preserved operation for low rectal cancer.

正确判断吻合口漏的发生及采用正确的处理方法是治疗的前提，双腔引流管加肛管引流是保守治疗吻合口漏的有效方法。

satisfying provision before operation and perfect anastomotic technology play key roles in preventing anastomotic leakage, correct judgement and valid method are premise of cure.irrigation and drainage through presacral double-cavity tube is a simple, safe and less suffering method to treat anastomotic leakage after anus-preserved operation for low rectal cancer.

充分的术前准备和良好的吻合技术是防止吻合口漏发生的关键。正确判断吻合口漏的发生及采用正确的处理方法是治疗的前提，双腔引流管加肛管引流是保守治疗吻合口漏的有效方法。

AFLP technique was applied on germplasm genetic diversity.It was abundant in Pyrus germplasm resources in China.

所筛选出的10个引物组合为梨属植物AFLP扩增多态性引物，可广泛用于梨属植物的AFLP扩增技术。

The10 primer combinations were high polymorphic primers, which could be applied widely on Pyrus L.By AFLP technique.

所选出的引物组合共扩增出371个位点，其中多态性位点306个，占总位点数的82.5%，每个引物组合扩增的位点数变化在23-55个之间，平均37.1个。
