The prediction of secondary structure showed that Family chensirin-2 and dybowsin-2 are extended coils, and the rest families have one or two a-helix where polar amino acids are located on one side of the helix wheel and apolar amino acids on the other side, attaching an amphiphilic property to the whole helix.

除dybowsin-2和chensirin-2家族为自由卷曲抗菌肽外，其余各类抗菌肽均能形成一段至两段a-螺旋结构，极性氨基酸和非极性氨基酸分别位于螺旋轮的两侧，使蝶旋呈两亲性。

These results suggest that contusional retinal edema is mainly due to disruption of cells in the outer retinal layer barrier may, in part, play a role in pathogenesis of the retinal edema.

The results reveal that many QTLs are involved in epistasis, and the same locus can get involved in interactions with more than one other locus.

结果发现，QTL除了具有自身的效应外，还可以参与上位性效应的形成，一个QTL可与多个QTL发生互作，可能起到诱发和修饰其他位点的作用。

Recent study have found that statins have lipid-lowering effect, multi-effect, including antioxygen, anti-inflammatory, immunomodulatory, lower levels of cytokines, improve endothelial cell function and prevention of thrombosis, reduce inflammation reactions.

近来的研究发现他汀类药物除了降脂作用外，还具有多效性，包括抗氧化，抗炎，免疫调节，降低细胞因子水平，提高内皮细胞功能和防止血栓形成，降低炎性反应等。

However, at the beginning of PVR process, stimulated and activated by the initiative factors, RPE begin to dislocate from Bruchs membrane , migrate, proliferate, dedifferentiate, transdifferentiate and secrete provisinal extracellular matrix proteins, followed by membrane formation and contraction on both surfaces of the neuroretina and in the vitreous body, resulted in tractional retinal detachment.

PVR发生后，RPE受到始动因素的刺激，开始活化，脱离原位，去分化，移行、增生、发生表型转化等，并分泌细胞外基质(extracellular matrix， ECM)，最终在视网膜前后表面和玻璃体内形成具有收缩能力的增生膜，造成牵拉性视网膜脱离。

Another six specimens of each group was obtained for biomechanical test at 8 weeks. RESULTS: There were no significant differences between control group and fibrin group. In bFGF group compared with control and fibrin groups, appearance of the angiogenesis, fibroblast proliferation and collagen production in the sheath, epitenon and parenchyma at repair site occurred earlier and were more in quantity, the gliding excursion of the tendon was shorter, and the work of flexion and the ultimate tensile strength of the tendon were greater.

结果：对照组与纤维蛋白封闭剂组间各项观测指标比较均无显著性差别，与对照组和纤维蛋白封闭剂组相比，bFGF组修复部位腱鞘、腱外膜及腱实质的新生血管形成、成纤维细胞增殖较好，胶原的分泌出现早，数量也较多；肌腱滑动距离较短，屈曲功和肌腱最大抗拉力较大。
