对再生胶的作用：粘稠的松焦油吸含其他的再生剂，其间的小分子能均匀渗透到含有结使硫的橡胶的大分子中间，使其溶胀，网状结构松驰，增加了分子链间的距离及氧的渗透，另外还可作为游离基的接受体，有抑制凝胶化的作用，还有助于活化剂向橡胶基质扩散加快再生过程，并能提高再生胶的粘性和可塑性，且污染较小，工艺性能好。

Moreover, the A-B-A triblock copolymer solution in a selective solvent, which is good for the block B, was explored. It was observed that the flowerlike micelles were formed, in which the central block B took on a loop conformation and the two end A blocks became a part of the micellar core. It was found that some of the soluble middle B blocks served as extended bridges between the small clusters by the poorly solvated end A blocks.

After the cell growth curves was recorded, RPE cells of the 3-5th passages were utilized. 2、Three different siRNA (siRNAl,siRNA2,siRNA3) targeting against human cx43 gene and one negative control siRNA were designed and transfected into cultured human RPE cells via liposome reagent. The most effective siRNA can be determined by semi-quantitative reverse transcription PCRRT-PCR. 3、To the most effective siRNA, after transfected into human RPEs with different concentration, the cellular proliferate activities were messured by MTT colorimetry ; the percentages of RPE in different cell circle phase was assayed by FCM; the changes of phenotypical properities were observed with SCM; the protein expression of cx43 was studied through immunocytochemistry stain and Weston blot; the communication intercellular was calculated with FRAP; and the ability of recovery was assessed by using an in vitro wound healing model.4、The total proteins of siRNA1 and RPE were seperated by two-dimensional gel electrophoresis and visualized by silver staining. Proteins with significant expression alterations were selected and their peptide mass fingerprints (PMFs were obtained by matrix-assisted laser desorption/ionization time of flying mass spectrometry (MALDI-TOF-MS).The PMFs were used to search NCBInr database by Auto MS-Fit software.
