Within two groups the phylogery of the glandular hairs in labiatae are also studied and the four elutionary lines of them are eastabilished.

在唇形科腺毛个体发育的基础上，我们对唇形科腺毛的系统发育也进行了研究，描述了唇形科腺毛主要的四条进化路线。

Was simultaneously injected into cisterna magna at the second injection blood in the presence of subarachnoid blood. At 2 to 4 days, GFP was expressed in leptomeninges over the brain stem, cortex and cerebral arteries, smooth muscle cells of small vessels were occasionlly transduced. GFP was expressed in adventitia of spastic basilar artery on days 2 (day 5 after first injection blood) after injection 〓, but was undetectable by days 4, transgene was not expressed in medial or intimal layers. The prensence of subarachnoid blood can not prevent access of adenovirus to vessels and transgene expression.

注入腺病毒载体后2天（初次注血第5天）行荧光显微镜、免疫组织化学和RT-PCR检测，结果在颅内大血管如基底动脉的外膜可见外源基因的表达，而外源基因不能转移至血管中膜和内膜，4天时（初次注血第7天）基底动脉的外膜中外源基因表达消失；注入腺病毒载体后2～4天，外源基因可以有效转移至颅底软脑膜细胞，小血管外膜和平滑肌层也可见外源基因的表达，表明蛛网膜下腔内的血凝块不能阻止腺病毒载体介导外源基因转移至颅内血管。

By analyzing MRI, MRU and clinical manifestations altogher, pelvic lipomatosis associated with proliferative cystitis can be correctly diagnosed using MRI images. Because proliferative cystitis can easily evolve into bladder cancer, patients with pelvic lipomatosis associated with proliferative cystitis should pay great attention and to perform timely follow-up checkups.

根据MRI、MRU与临床特点的综合分析，MRI能够正确诊断盆腔脂肪增多症合并腺性膀胱炎，由于腺性膀胱炎易演变为膀胱癌，因此，对于盆腔脂肪增多症合并腺性膀胱炎的患者应高度重视，密切随诊复查。

In the article, we took part sample out of 158 patients to exam the expression level of Bcl-2 and Fas in myasthenic thymus tissue, and to find the role of which in whole pathogenesis. we also try to find the role of neopterin and sIL-2R through examing the concentration of neopterin and sIL-2R in peripheral blood of 26 MG patients. Material and methods1.select of case: to choose 158 patients who wear followed up from 1988 to 2002 after operation. All patients were diagnosed as MG, and treated with same medical cure during period of preoperation and post operation. 2.Collectionofdata:.To collect all data through designing a uniform follow-up table for thymectomized patients ,and to analysis the effect of factors including age, gender, disease duration of preoperation, clinic types and pathological types to prognosis at three follow-up period?

本文拟在对全组病例的远期预后进行流行病学统计分析的基础上，通过抽取一定量样本，研究重症肌无力患者胸腺组织中伽 12、Fas的异常表达及生发中心的形成在重症肌无力发病机制中可能的作用，以及它们对胸腺切除术后远期预后的影响；与之相似，通过检测部分样本外周血清中新碟吟和可溶性IL－2受体的浓度及其与正常对照组的差异，以期推测两者在重症肌无力起病及病情进展中的作用和意义，并分析其对胸腺切除术后远期预后的影响。

The expression of Cat V was significantly raised in the epithelial-rich and mixed cell thymomas when compared with that in the lymphocyte-rich ones. No statistically significant difference was found on the variables such as perioperative myasthenic crisis, sex or age of patient, duraton of sickness and expression of Cat V.

上皮细胞型(75.00%)和混合细胞型(85.00%)胸腺瘤中Cat V阳性表达率显著高于淋巴细胞型(21.21%)(P.01)，而上皮细胞型与混合细胞型之间差异无统计学意义；良性与恶性胸腺瘤中Cat V阳性表达率差异无统计学意义；男性患者与女性患者之间、35岁以上患者与以下患者之间胸腺瘤中Cat V阳性表达率差异均无统计学意义。

结果191例卵巢冠囊肿患者中有175例(91.62%)为单纯囊肿；15例(7.85%)为上皮性囊肿(其中13例为浆液性囊腺瘤，1例为浆液性乳头状囊腺瘤灶性交界，1例为副中肾管源囊腺瘤、腺体增生并中重度非典型性增生)；1例(0.53%)为高分化乳头状间皮瘤。

The results were as follows: Compared with control group, the weight and the relative weight of thymuses, bursas of Fabricius and spleens of experiment group increased significantly(P＜0.05) or extremely significantly(P＜0.01). In experiment group, the cortex of thymic lobule, bursa nodule and Periarterial Lymphatic Sheaths thicken obviously; the volume of bursa nodule, splenic nodule and ellipsoid augmented, and the germinal center of splenic nodule were obvious; the thymic corpuscle increased; the plica of bursas of Fabricius developed well and the degenerating of it retarded.

结果表明：试验组鸡胸腺、腔上囊、脾的重量和器官指数均高于对照组，差异显著(P＜0.05)或极显著(P＜0.01)；试验组的胸腺小叶皮质增厚，胸腺小体增多；腔上囊皱襞发达，腔上囊小结体积大，皮质较厚，退化延缓；脾的动脉周围淋巴鞘增厚，脾小结体积大，生发中心明显，椭球增大。

目的： 检测重组腺病毒质粒在HEK293细胞中的稳定性；重组腺病毒是否与减蛋综合征阳性血清发生中和反应，以及用重组腺病毒免疫SPF小鸡是否产生保护。

ABSTRACT AIM: In order to find new type of antitumor compounds and study the contribution of hydroxyl groups on the sugar part to the antitumor activity of 8-Cl-adenosine, the retinoid analogs of adenosine and the derivatives of 8-Cl-adenosine were synthesized.

目的： 为寻找新型抗肿瘤化合物和探讨糖环羟基对8-Cl-腺苷的抗肿瘤活性的影响，合成了腺苷的维甲类似物和8-Cl-腺苷衍生物。

Viral vector mainly contain adenovirus, retrovirus,adeno-associated virus and so on, but it has potential danger of safety; it isrepeled by immune system when it is injected to organism for a greatimmunogenicity. An injection with adenovirus vector with highconcentration, it leads to serious inflammatory reaction of liver. Viralvector such as liposome and polycation are commonly used lately. But,liposome and polycation have low specificness and targetness of genetransfer tissue, have lower transfection efficiency and short period ofgene expression, for they can be phagocytized by endothelial system.

许多的载体，病毒载体和非病毒载体以前已广泛应用，病毒载体主要包括腺病毒，逆转录病毒，腺相关病毒等；但病毒载体在安全性方面存在潜在的危险；免疫原性比较强，注射到机体后很快会被机体的免疫系统排斥，当静脉注射高浓度的腺病毒载体会使肝脏发生严重的炎症反应；非病毒载体目前常用的有脂质体及多聚阳离子聚合物；但脂质体和阳离子聚合物介导基因转移缺乏组织的特异性和靶向性，转染效率较低且易被网状内皮系统吞噬，基因表达时间短；因此研制新型的非病毒载体已成为研究的热点，纳米颗粒具有小尺寸效应，表面效应，随着颗粒直径变小，比表面积将会显著增大，故具有很高的化学活性，因而纳米成为了最有应用前景的非病毒载体。
