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.

MCP could effectively delay the softening of climacteric fruit, such as Starking and Fuji apples and Feicheng peach, but as different fruits had different softening mechanism, the mechanism of 1-MCP inhibiting different fruit softening was different: in Starking apples, the key enzyme to the softening is endo-and exo-PG, while during Feicheng peach fruit softening, the key enzyme was EGase before the 20th d and endo-PG after 20th d during storage at 0℃. 1-MCP inhibited fruit softening mainly by inhibiting PG activity in Starking apple while in Feicheng peach, by inhibiting the activity of EGase in the earlier storage time and endo-PG in the latter time. It was also found that LOX accelerated the initiation of the softening and was regulated by ethylene and 1-MCP in apple and peach.

2.1-MCP能较好的延缓红星、富士和肥城桃等跃变型果实硬度的下降，但是不同品种/树种的果实软化机理不同，1-MCP抑制其软化的机理也不一致：在红星果实中，对软化起主要作用的酶一直为内切和外切两种PG，而在肥城桃软化过程中，前20d以纤维素酶活性起主要作用，20d后软化以内切PG为主。1-MCP主要通过抑制红星果实中PG酶活性来抑制果实硬度的下降；在肥城桃果实中，1-MCP通过抑制前期纤维素酶和后期内切PG活性，延缓了果实硬度的下降。
