Studies on genetic diversity: 252 bands were amplified by 20 primers in Carya cathayensis ,168 bands were polymorphic and PPB was 66.7%. 238 bands were amplified by 20 primers in C.dabieshanensis .162 bands were polymorphic and PPB was 68.1%.

群体遗传多样性研究：20条引物在山核桃群体中共扩增出252条谱带，其中，多态性条带168条，PPB为66.7％；20条引物在大别山山核桃群体中共扩增出238条谱带，其中，多态性条带162条，PPB达68.1％。

In this study 24 cpSSR primer pairs were screened, and four pairs were found producing DNA fragment length polymorphism from the tested populations of Castanea mollissima.

对24对cpSSR通用引物进行筛选，选用4对呈现多态性的引物对板栗的4个野生居群和9个地方品种群进行遗传分析。

Based on 16 primers which are of stable polymorphism selected from 200 random primers, RAPD polymorphism of 38 Chimonanthus praecox cultivars was analyzed.

从200个随机引物中筛选出16个多态性稳定的引物，对38个蜡梅品种进行遗传多样性和亲缘关系RAFD分析。

Percutaneous transhepagtic drainage of gallbladder was a safe and simple technique, it drained infected bile equally as surgical cholecystostomy; and it was of benefit to aged or patient of high surgical risk.

经皮穿肝胆囊引流术是一种不需要手术，即可提供相当於胆囊造瘻术的技术，在局部麻醉下很快地把感染的胆汗引流体外，令临床症状得以快速改善；由於此技术的安全简便及侵袭性小，对於需要紧急进行胆囊造瘻术的年老病人或高手术危机者，有著极大的裨益。

T tube drainage was able to decrease bile viscosity effectively.The number of bacteria decreased significantly until 21 postoperative days.The time that T tube is drawn out is on 14 postoperative days.Bacteria may exist in bile continuously and play a role on relapse of choledochitis and bile duct stone.

胆汁中的细菌和粘度升高在胆管结石形成中起协同作用。T管引流能有效地降低胆汁粘度，而胆汁中细菌量在引流术后第3周才有显著减少，临床2周时拨除T管细菌可潜伏下来，对胆管炎和胆管结石的复发可能起作用。

Objective To evaluate whether the internaltube discharge time have influence on therapeutic effects in the patients with internaltube drainage of laparoscopic choledocholithotomy.

目的：探讨腹腔镜胆总管切开取石及置管内引流术后内置引流管排出时间对疗效的影响。

Laparoscopic choledochotomy with endobiliary catheter and primary closure of CBD is a safe, effective and feasible procedure for the management of choledocholithiasis.

腹腔镜胆总管切开探查后放置胆道内置管引流胆总管一期缝合是一种安全、有效、可行的胆道引流方法。

Methods From March 1992 to January 2005, there were 395 cases undergoing LCDET, involving choledochotomy, electrohydralic lithothipsy, dilation stenosis, stent placement and T-tube drainage.

从1992年3月～2005年1月，运用腹腔镜胆总管探查T管引流术的手术方式，包括胆总管切开，胆管镜取石，液电碎石，扩张狭窄，放置支架，T管引流，对395例病人进行治疗。

Main methods included choledochotomy, choledochoscopic exploration,ureteral catheter through cystic duct remnant for drainage of bile duct,Ttube drainage,and the primary closure of duct incision.

1993年10月至2005年3月运用腹腔镜胆总管切开取石术(包括胆总管切开，胆管镜取石，经胆囊管残端输尿管导管胆管引流、T管引流、胆总管切口即时缝合等)有选择地对87例胆总管内径≤08cm的胆总管结石病人进行治疗。

A first embodiment comprises a first common primer sequence, a first template homology region, a cleavable site, a second common primer sequence and a second template homology region.

第一个实施方案包含第一通用引物序列、第一模板同源性区、可切割位点、第二通用引物序列和第二模板同源性区。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
