Anisodamine causes interdigitation in DPPG, whose phospholipid molecules insert into the opposite lipid layer with the ends of the acyl chains near to the 5th carbons of the opposing lipid molecules, whereas anisodamine can not cause interdigitation in DPPC existed generally in membranes.

山莨菪碱诱导DPPG脂质体交插结构，其脂酰链末端插到对面分子层脂酰链第五个碳原子的位置，而生物膜中普遍存在的DPPC不能被山莨菪碱诱导形成交插相，但DPPG／DPPC混合物则能形成交插相，即伴随DPPG的交插，DPPC分子也发生交插。

Molecular configurations in LB films undergo change from keto form to zwitterion assurface pressures increase,companied by intermolecular hydrogen bonds decreaseand intramolecular hydrogen bonds increase.

ConclusionF022 from Radix Isatidis can not only destroy the structure of endotoxin, but also obstruct the signal transduction pathways of LPS. F022 may be a strong antiendotoxin fraction in drugs research and development.

结论F022部位不仅直接破坏内毒素结构，且阻断内毒素引起的信号传导通路，从而抑制机体炎性因子的过度释放、抑制膜结构伸展刺突蛋白和丝裂原活化蛋白激酶的表达，从分子水平阐明了板蓝根中活性部位F022抗内毒素的分子机理。

Combined the membrane morphology and the ternary system phase diagram, it is considered that, which is the results of the cooperation of binodal liquid-liquid demixing and spinodal liquid-liquid sub-demixing during the membrane formation process.

不同铸膜液溶解温度下胞腔的大小与PVDF分子和溶剂分子间的溶剂化作用、高分子线团的构象变化等因素有关。

From the early study of the pathogenesis of pre-eclampsia people have found its association with immunological function . In 1986 Ellis et al[1] had found that the extravillous chorionic cytotrophoblast contacting with the maternal tissue expressed high levels of Human leukocyte antigen-G, a major histocompatibility tissue-specific antigen . Extravillous chorionic cytotrophoblast with high levels expression of HLA-G proteins can invade the maternal deciduas and the maternal spiral arteries by displacing the endothelial lining and destroying most of the musculoelastic tissue of these arteries .

早期研究开始，许多学者即发现其与免疫学有密切关系，至1986年Ellis等[1]发现人类白细胞抗原(human leukocyte antigen，HLA) G分子高度表达在绒毛外滋养层细胞( extravillous cytotrophoblast，EVCT)上，即浸润至子宫蜕膜层甚至达子宫浅肌层以及子宫螺旋动脉内皮层，与母血及子宫组织直接接触的滋养细胞，这种独特的组织分布提示HLA-G分子在母胎免疫耐受方面起重要作用。

To regulate tumor cells proliferation and metastasis. In many malignant tumors, CD44 has shed by MT1-MMP extracellularly, and causes the release of the soluble CD44, which facilitate the tumor cells motility.
