Isolation, cultivation and identification of human embryonic NSC from cerebral cortex of 7-12 week abortus. By using flow cytometry and MTT assay, the effects of various concentration of TSPG and TSPG cooperating with cytokines in NSC culture media for 3 days on proliferation of human embryonic NSC has studied. By employing immunocytochemistry assay of the expression of tyrosine hydroxylase, the effect of different dilution of TSPG and TSPG cooperating with IL-1 on induced differentiation of human embryonic NSC into dopaminergic neuron has researched.

Abrin is one of the potent toxins isolated from the beans of plant abrus precatorius.the toxic protein consists of two disulfide-bonded subunits,the a and b chains.the b chain is a galactose-specific lectin that facilitates the binding of abrin to the cell membrane that precedes endocytosis.after entering the cells,the a chain catalytically inactivates 60s ribosomal subunits by removing adenine position 4324 of 28s r–rna,and thereby inhibits protein biosynthesis.

相思子毒素是从豆科植物(abrus precatorius l。)种子中分离的一种细胞毒性蛋白。它由a，b两条链组成，由一个二硫键相联，b链具有半乳糖凝集活性，可与细胞膜上受体结合，帮助a链进入细胞内，a链进入细胞催化失活60s核糖体亚基，从而使细胞蛋白合成被抑制。

Equal amount of absolute alcohol was given to the control group. The expressions of vitamin D receptor in HL-60 cells of each group were identified by Western blot analysis, and cellular morphological changes were observed after being stained by Wright-Giemsa.

Antimetastatic effect of aspirin, RD, magnesium acetysalicylate on experimental metastasis of SACC was observed in vivo.

体外实验观察高转移潜能的SACC-LM细胞、非高转移潜能的SACC-83细胞与血小板的粘附，阿斯匹林、阿斯匹林镁、精氨酸-天冬氨酸（arginina-aspartate，RD）对SACC-LM细胞与血小板粘附的影响；动物实验观察阿斯匹林、阿斯匹林镁、RD对SACC-LM细胞实验性肺转移的作用。

Bronchoalveolar lavage and wright staining analysis showed that thetotal number of the all inflammatory cells in asthma model group andthe normal control were (36.2±4.6)×10~6/ml and (9.5±1.6)×10~6/ml.There was significant difference between the two groups (p＜0.01).Meanwhile, the number of acidophilic cell, macrophage andmacrophage were also increased in asthma model group rather thanneutrophilic granulocyte.

支气管肺泡灌洗和细胞记数显示，哮喘模型组支气管肺泡灌洗液细胞总数为(36.2±4.6)×10~6／ml，与正常对照组(9.5±1.6)×10~6／ml，相比显著增加(p＜0.01)，同时嗜酸性细胞、巨噬细胞和淋巴细胞增加明显，而中性粒细胞变化不明显。

Actinomycin D is the potent inhibitor of RNA synthesis, and is demonstrated to be able to induce Sf-9 cell, K562 cell, aleolar macroages cell CTLL-2 and Jurkat cell apoptosis.

放线菌素D是RNA合成抑制剂，具较强的诱导细胞凋亡的能力，实验证明放线菌素D可诱导Sf-9细胞，人白血病细胞株K562，肺泡巨噬细胞，CTLL-2和Jurkat细胞等凋亡。

In order to confirm this suspect, we choosed a cultured rat granulation tissue fibroblasts model in vitro and applied RT-PCR and cell-ELISA technology to detect the changes of firbroblasts intrinsic EGF, bFGF, TGFβ-1 with their receptors gene expressions and protein synthesises after stimulated by SP. Our purpose was to explore the possible effects and patterns imposed by SP on fibroblasts intrinsic growth factors and their receptors expressions, which maybe offer theoretical basis for promoting wound healing via improving nervous functions and regulating neuropeptides secretions.

为进一步验证这一推测，同时排除在体多因素干扰，我们采用了一种大鼠肉芽组织成纤维细胞体外培养模型，采用RT-PCR与细胞ELISA技术，检测SP刺激成纤维细胞后，成纤维细胞内源性EGF、bFGF、TGFβ-1及其受体基因表达和蛋白合成的改变情况，探讨SP对成纤维细胞内源性生长因子及其受体表达的影响以及方式，以期为经由改善神经功能、调节神经肽分泌途径促进伤口愈合提供理论依据。

The animal model of this method system have, the characteristics of the high fat, high leptin, high Ins, and match with the characteristic of clinical and the pathologic of simple obesity. This studies showed: The acupuncture can obviously reduce the vaule of intaking food and water of the fat rats, and lower the body weight and fat; The acupuncture can urge the diameter, area, physical volume of white fat cell contract, Brown fat tissue of fat rat group surroundings vascular containing large quantity of white fat cell, the acupuncture group was less. this showed: The acupuncture enhanced the white fat cell metabolism, and promotesed the white fat cell to convert to brown fat cell; The frequency of spontaneous electric of nerve cell of pvn of the fat rat is high, the acupuncture counld depress the spontaneous electric of nerve cell of pvn, This showed: the acupuncture can depress the appetite passing to adjust function of pvn nerve; The monoaminergic neurotransmitter of inside of the fat rat brain is disfunction, the acupuncture can rectify this disfunction, and adjust level of 5-HT, and affect appetite, and improve metabolism; The level of leptin and Ins of fat rat increased high, The level of it of acupuncture group decreased, compared with the fat group p.001, This showed: the fat rats have the defeat of leptin and Ins in the body, The acupuncture can lowering this defeat, The level of leptin and Ins of the fat rat in the brain is less than the normal group, The level of leptin of the acupuncture group is high than the fat group, This showed: the acupuncture can increase the transportation of leptin from blood to brain.

本方法所制肥胖大鼠模型具有高体重、高脂、高leptin和高Ins血症的特点，符合人类单纯性肥胖病的临床和病理特征；实验研究显示：针灸能明显减少肥胖大鼠的摄水、摄食量及降低其体重、体脂；针灸能促使白色脂肪细胞直径、面积、体积缩小，减少肥胖大鼠棕色脂肪组织血管周围白色脂肪细胞数量，显示：针灸增强了白色脂肪细胞的代谢，促进了白色脂肪细胞向棕色脂肪细胞的转化：肥胖大鼠PVN神经细胞自发放电频率增加，脑内单胺递质紊乱，针灸通过抑制PVN亢奋的自发放电，调整5-HT水平，达到影响食欲，改善代谢的作用；肥胖大鼠血中leptin及Ins水平增高，与正常组大鼠比有明显差异，提示大鼠体内存在leptin及Ins抵抗，针灸后肥胖大鼠随着体重体脂的下降，血中leptin、Ins水平降低，与肥胖组比均有显著性差异，而针灸后大鼠脑内leptin增加，与肥胖组比P.05，提示：针灸具有改善leptin、Ins抵抗及增加leptin脑内转运的作用。
