Objective: The modern medical research thought that the cerebral ischemia- reperfusion injury is an important pathophsiology mechanism that causes the various cerebral disease,and apoptosis is one of the important mechanisms of the cell death in the process of the organ and the organization ischemia-reperfution.

目的：现代医学研究认为缺血再灌注损伤是大多数急性缺血性疾病的主要病理生理过程，而细胞凋亡则是器官、组织缺血再灌注损伤过程中细胞死亡的重要机制之一，因此干预细胞凋亡，从而防治缺血再灌注损伤已经引起国内外广泛关注。

Perceptively on 3d and 5d. Collagen is positive in Western blot on 9d. Aniline dyeing is positive on 12d. The control group was negative. Ad-BMP-2 transferred MSCs cultured in fibrin gel was positive in Aniline dyeing, Immunohistochemical. The therapy effect of group was better in histology, biochemistry and biomechanics in all periods than the other two groups, and was similar to the natural cartilage.

结果 ①Ad-BMP-2转基因MSC BMP-2、CollagenⅡ的PT-PCR分别在3、5d呈阳性，CollagenⅡ的Western Blot 9d为阳性，较对照组有显著差异；②转基因MSC经纤维蛋白体外三维培养后免疫组化和苯胺蓝染色呈阳性，电镜显示细胞生长良好，有基质合成；③转基因修复组各时期大体、组织形态学和组织化学成份均显著优于其它两组，12W时力学和组织学已接近正常关节软骨。

Nowadays, it was known that auricular cartilage can roughly be separated into three layers: fibrous, cambium and cartilage layer. The fibrous layer is at the outer part of perichondrium, and the cambium layer is the inner part.

目前已知在软骨组织大致可分三层细胞，包括最外侧的纤维层、软骨组织及在软骨组织表层的形成层。

RESULTS: Levels of insulin, FFA, GOT and GPT in serum were significantly increased in model group; activities of T-SOD and GSH-Px in liver tissue and ISI were notably decreased, and content of lipid perhydride MDA was increased. HE staining revealed that there was hepatic cellular swelling in hepatic lobules, inequality of size of lipid droplets in periplast, nucleus on one side, narrowed sinus hepaticus and inflammatory cell infiltration in hepatic lobules and portal area.

结果： 模型组大鼠血清胰岛素、FFA、GOT和GPT水平明显升高，肝组织中T-SOD和GSH-Px活力和ISI明显下降，脂质过氧化物MDA含量显著增加， HE染色示肝小叶中大部分肝细胞肿胀，胞质中出现大小不等的脂滴空泡，以大泡性脂肪滴为主，核居边，细胞界限不清，肝窦狭窄，且存在小叶内及门管区炎症细胞浸润。

Considering other differences that in leaves of Podocarpus there are three resin ducts under vascular bundle of midrib, mesophyll cells are differentiated into palisade tissue and sponge tissue; in leaves of Nageia, there is only one resin duct under vascular bundle in each vein and no obvious differentiation in mesophyll cells, palisade tissue can be found on both sides, and sclereids can also be found in mesophyll tissue.

结合罗汉松属植物主脉维管束下面有3个树脂道，叶肉分化为栅栏组织和海绵组织，而竹柏属植物每个叶脉维管束下面有1个树脂道，叶肉分化不明显，两面都有栅栏组织，叶肉中还具有大量石细胞等特征，认为罗汉松属和竹柏属在叶脉、叶形态和结构方面存在明显差异，2个属分开是比较合理的。

The T cells in nasal polyps express high CD69 and are activated, producing Th1/Th2 mixed cytokines with change of cytokine secretion predomination, probably owing to the formation of microenvironment of the nasal polyps and the mucosa immune system.

鼻息肉组织中的T细胞高度表达CD69分子，处于免疫活化状态，产生Th1/Th2混合模式的细胞因子，与外周血相比Th细胞因子分泌优势发生改变，可能与鼻息肉"微环境"形成及黏膜免疫系统有关。

Using the Hprt gene as a positive control, our result suggested that both the testis tissue and the male embryos from which Sry transcription can be detected failed to yield any positive results of Xist. Female embryos at the pronucleus stage and 2-cell failed to produce any positive result of Sry and Xist too.

然后利用实验一确定的PCR条件，以Hprt为阳性对照，用巢式RT-PCR对小鼠早期胚胎进行Xist基因的转录分析，结果发现，转录Sry基因的睾丸组织以及雄性胚胎，从受精卵发育到囊胚的过程中，基本上不转录Xist基因；不转录Sry基因的雌性卵母细胞和雌性胚胎，从出现原核开始，到发育至2-细胞期的过程中，Xist基因一直不转录，但是，从4-细胞期开始，一直到孵化前囊胚阶段，雌性胚胎都转录Xist基因。

In order to investigate the inhibitory effect of salvia miltiorrhiza and tetramethyl pyrazine on scartricial fibroblast, the hypertrophic scar tissue of chest was chosen for culture of fibroblasts, and the influence of SM and TP on fibroblasts was observed, The effect of the drugs on the growth of fibroblasts, on DNA synthesis of fibroblasts and on mitosis index of fibroblasts were all determined quantitatively.

摘 要 增生性瘢痕是临床治疗难题之一，目前尚无有效的治疗方法。为了探讨丹参和川芎嗪对瘢痕成纤维细胞的抑制作用，取12例患者胸部增生性瘢痕组织，通过体外成纤维细胞培养，探讨不同药物浓度、不同作用时间对成纤维细胞生长的影响。

Bone is a complex tissue composed of several cell types and the two major of them responsible for bone remodelling are osteoclast, which resorb bone, and osteoblast, which form new bone.

中文摘要骨骼是具有数种细胞型态的复杂组织，而其中最重要的两种分别是负责骨吸收作用的破骨细胞及职司骨生成的造骨细胞。

Results The anesthesia range was narrowed and anesthesia duration was shortened with the prolongation of epidural catheter placement,Epidural roentgenography showed that the medium diffused normally within epidural space,biopsy of epidural tissues showed that there were inflammative cells infiltration and fiber proliferation with longer epidural catheter placement（more than 4 weeks）,without significant differences between both groups.

结果 随着硬膜外腔置管时间延长，麻醉阻滞范围变窄，麻醉阻滞时间也明显缩短，两组之间没有明显区别；硬膜外腔造影显示：造影剂在硬膜外腔扩散良好，无明显受阻；组织学检查显示：置管时间长(4周以上)的动物，硬膜外组织炎细胞浸润、纤维组织增生、硬膜增厚，而且随置管时间延长，变化加显著，但两组之间没有明显区别。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
