DMBQ, ferulic acid and resorcin were effective chemical signal substances in the process of seed germination and haustorium formation of Cistanche deserticola. 4.The embryo is consist of 12 cells, the endosperm cell degraded so as to provide nutrition for the embryo development .As a result, germ tube differentiated from the embryo and came out through micropylar end, the small cell at the tip of the germ tube held the capacity of cleavage and the other cells grew big ,so the germ tube elongated .The anterior extremity of germ tube swelled to form haustorium under chemical substances treatment, the haustorium cell stained ,especially its portrait because of the lignification of the cells.

肉苁蓉种子的胚是由12个细胞紧密排列形成的圆球状胚，球形原胚分裂增殖的同时，胚乳细胞分解，为胚细胞的增殖提供营养，最终胚上分化出的芽管由珠孔端冒出，芽管前端细胞较小，具有旺盛的分裂能力，后部细胞体积增大，芽管逐渐伸长，在化学物质的诱导下，芽管由中部至前端细胞膨大分化出初生吸器，初生吸器呈帽子状，而这些细胞比其周围的细胞着色深，吸器纵向局部区域的番红染色加深，细胞高度木质化。

I will apply Immumohistochemical method to detect proliferating cell nuclear antigen expression of lung adenocarcinoma histiocyte inpatients, and I will study apoptosis of lung adenocarcinoma cells by TUNEL method; calculate PCNALI and ALI; compare and analysis PCNALI and ALI of different patients with different clinic features simultaneously .

例肺腺癌组织中增殖细胞核抗原的表达，同时通过TUNEL法检测肺腺癌细胞凋亡，计算PCNA增殖指数和细胞凋亡指数，对不同临床特点肺腺癌患者的PCNALI、ALI进行比较分析。

In general, the function of ERαis mainly in the process of hyperplasia and histogeny of cell and tissue.

一般来讲ERα主要在组织细胞的增殖和分化过程中起主要作用，而ERβ在卵泡、骨骼发育和抑制细胞增殖方面发挥作用。

Methods:(1) Bone marrow stromal cells isolated from Beagle dogs were cultured in vitro for the primary culture,in basic medium consisted ofDMEM^iew horning cattleerum,etc. Parts of subculture were cultured in mineralization medium which additionally contained 50 y g/ml ascorbic acid, 10mmol/LNa- beta -Glycerophosphate and 10-8mol/L dexamethasone in order to induce cells differentiating into osteoblasts.

①抽取毕格犬髂骨骨髓体外分离培养获得骨髓基质细胞，DMEM、新生牛血清培养基进行原代培养，部分传代细胞以含10~(-8)mol/L地塞米松、50μg/ml抗坏血酸和10mmol/Lβ—甘油磷酸钠的矿化培养液诱导其向成骨细胞增殖分化，用倒置相差显微镜进行细胞形态学和细胞生长增殖观察。

The degradating and redistributing of ECM were migration of VSMC and vascular remodeling through inhibiting the production of PDGF-BB and the activation of MMPs so to prevent the vascular stenosis.⑤Orthotopic hybridism in situ: The expression of MMP-3 increased after operation, the tendency and intensity were parallel to the expression of NF-κB. Tongxinluo could decrease the expression of MMP-3 and NF-κB. The study showed that the producting and activating of MMP-3 were modulated by NF-κB. The inhibition to the producting and activating of MMp-3 of Tongxinluo was mediated by inhibiting the activating of NF-κB. Conclusion ①The rabbit vascular stenosis model could be established successfully by plain balloon damage, the operation process was easy, economical and practical.

①单纯球囊损伤可成功建立典型家兔血管狭窄模型，操作方法简单，经济实用；②以VSMC增殖、迁移为主的内膜增厚以及以ECM降解、合成与再分布所致的血管重构是导致受损血管狭窄的根本原因；③通心络能明显抑制VSMC的增殖、迁移和ECM降解、合成，阻止血管内膜增生和血管重构，防止受损血管狭窄；该作用可能与其减少和阻止PDGF-BB的产生和活性，以及抑制MMPs的表达和恢复MMPs/TIMPs平衡有关；④通心络能显著抑制球囊损伤后血管内膜增生和血管重构，可能与其保护血管内皮，改善内皮功能，增加血清NO含量有关；⑤通心络抑制内膜增生和血管重构，减轻受损血管狭窄，还可能是通过抑制NF-κB的活化途径而起作用的。
