The floral morphogenesis of Coptis was observed under scanning electron microscopy. The initiation of all floral organs of the genus is spiral, the petal primordia are slightly retarded, the developmental sequence of the stamens is centripetal,the carpel primordia are conduplicate (i.e., horse-shoe shaped), the ovaries are half closed and the ovary stalk is formed in the developmental process.

Results l.Serum concentrations of VCAM-1 in PIH (93.39 + 57.3)ug/ml were higher than that in normal pregnant group. Serum concentrations of VCAM-1 in moderate(97.89 + 34.07)ug/ml and severe PIH(132.24 + 60.97)ug/ml were significantly higher than that in normal group.(P.05, P.01). There was no difference between serum levels of VCAM-1 mild PIH and normal pregnant group. 2.Serum levels of IL-6 in PIH group(102.17 ?48. 31)pg/ml were significantly higher than that in normal group(49.16 + 12.9)pg/ml.Serum levels of IL-6 in moderate(95.79+31.19)pg/ml and severe PIH( 127.27+11.3 8)pg,ml were significantly higher than that in normal group. There was no difference between serum levels of PIH in mild PIH (52.13 + 12.90)pg/ml and normal pregnant group. 3. In PIH group, serum concentrations of VCAM-1 correlate with the levels of IL-6,r=0.63. 4.The expression of VCAM-1 in cytotrophoblast of spiral arteries in normal pregnant group(100%) were significantly higher than that in PIH group.Theexpression of VCAM-1 in moderate PIH(37.50%) and sever PIH were lower than that in normal group.There was no difference between the mild PIH and normal group.Conclusions The increased levels of serum of VCAM-1 may participate in the process of vascular endothelium damages in PIH.

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。
