This article bases on the materials that made by former scientists and focuses on the origination and evolution of eucaryotes(something that the writers have been thought about for a long time ),using the new discoveries that Graidia lamblia contains mitosomes and introns as a lead.

本文以蓝氏贾第鞭毛虫具有线体和内含子这两个新发现为引，在查找大量前人的资料数据后，提出了笔者对真核生物起源与进化的一些思考，认为其二者均是基因横向转移的结果。

The species have the highly homogenous sequence in the ITS, while the numbers of the different bases is from 94 to 100 in pairwise comparison with the genus Lepidium. So the outgroup, Lepidium, is appropriate in our study.

与外类群相比，菘蓝属属内分类群的序列间具有更高的同源性，菘蓝属各类群与独行菜属外类群的遗传距离均很大，碱基差异在94～100个，说明本实验以独行菜属植物作外类群是合适的。

This study is to investigate the pharmacodynamics and pharmacokinetics of LEVO for lumbar epidural anesthesia in , and provide theoretical bases for rational administration of LEVO during clinical anesthesia.

本试验旨在了解LEVO用于腰段硬膜外麻醉的药效学与药代动力学特性，为临床麻醉合理安全用药提供理论依据。

In order to reduce the non-specific binding between oligonucleotides and bases mutation caused by the complicate secondary structure of DNA and excessive PCR amplification, a frequently phenomenon in one-step gene synthesis, we used a two-step method including assembly PCR and digestion-ligation step to synthesis Aspergillus niger lipase gene lipA.

本研究主要针对一步法长片段基因合成中复杂结构的非特异性配对和过多的PCR引入碱基错配等问题，采用二步法(组装PCR和酶切-酶连)合成了黑曲霉脂肪酶基因lipA。

Objective A prospective study was organized to determine the accuracy and costeffectiveness of the TB AccuProbe DNA hybridization test,the PCR bases LiPA assay,and a verifying automated DNA sequencing of the rpoβ gene,for the routine rapid and direct identification of the Mycobacterium tuberculosis complex and Non Tuberculosis Mycobacterium and rifampin susceptibility.

目的用 3种先进的技术-TBAccuProbeDNA杂交法、INNO LIPATMRIF TB探针试验和rpoβDNA基因序列测定的前瞻性研究，以鉴定结核分枝杆菌复合物和非结核分枝杆菌及其成本效益。

The main target of PDT-CPD4 was probably membrance organelles, such as cytomembrance、lysosome、microsome. It made lipide and protein of these membrance dissociate and degenerate, membrance penetration increased. Typical biochemical changes appeared, 180bp bases DNA fragmentation ladder pattern was observed in agar electrophoresis.

但PDT作用后出现线粒体肿胀，可能是因为PDT的主要靶部位是膜性细胞器如线粒体、胞质膜、内质网和溶酶体等，光化学反应产物使这些膜的脂类和蛋白质发生分解变性，膜通透性增高所致。

Their approach to seed creation still bases itself on an addiction to microcosmic thought rather than macrocosmic.

他们的办法，建立种子基地仍然在自己的瘾，而不是微观宏观思考。

Magnetotherapy is an effective method of treatment,that bases on the traditional meridian theory,and it has been proven effective for many kinds of common diseases,frequently-occurring disease by massive clinical observations.

磁疗法是以传统经络学说为依据，并经大量临床观察证实对多种常见病、多发病行之有效的治疗方法。
