We have researched distribution of TGF β and its receptor in various age group and discs of various degeneration grade, found that positive ratio of TGF β and its receptor is higher in below 40 year old group and discs of MRI Ⅰ and Ⅱ grade, mainly occur in fibrous cartilagous cells of fibrous annulus and nucleus pulpous; In group of 40-60 years old and grade Ⅱ and Ⅲ discs, TGF β decreased and TGF β R decreased not as much as TGF β; In above 60 years old group, TGF β and its receptor almost disappear.

生长因子包括TGF-β对细胞功能有重要调节作用，它是一种相对分子质量为2.5×10〓的二聚体多肽，几乎参与了哺乳动物所有细胞的病理，生理过程，尤其是在细胞外基质的产生及调控方面意义重大，且TGF-β已被公认为是与胶原代谢关系最密切的细胞因子。胡有谷、陈宏等，应用杂交技术检测了TGF-β对椎间盘Ⅰ、Ⅲ型胶原MRA的调节作用。

Methods: MUC1/Y extracellular domain was used as a target molecule to biopan Ph. D. 12 phage randem peptide library. Two protocols using affinity gel and cell culture plates respectively were carried out. Positive phage clones were identified by ELISA. ssDNA sequencing was done on 16 positive phage clones to get the amino acid sequences of MUC1/Y-binding peptides. Immunohistochemistry was done to show the capacity and specificity of positive phage clones to bind the tumor cell lines.

吴春根 王松梅高红阳潘銮凤复旦大学上海医学院细胞与分子生物学实验室，200032摘要：目的尝试用十二烷基肌氨酸钠作为脱细胞试剂，制备脱细胞组织工程支架材料，并分析其生物学性能。

The results showed that intermidiate 1, 2-propanediol-sebacate of low relative molecular mass was synthesized with toluene-p-sulfoinc acid as catalyst, benzene as watercarrying agent, and of mole ratio of sebacic acid to 1, 2-propanediol of 1:4. The glass-transition temperatures of PPSC were below 0 ℃ which confirmed that PPSC would be in a high-elastic state of ambient temperature and human body temperature. PPSC was a elastomer with moderate crosslinkage, low module and high elongation, and had rapid degradation ratio (degradation degree more than 50%) in phosphate (pH value 7.4) at 37℃.

结果表明，以对甲苯磺酸为催化剂、苯为带水剂，在酸醇比为1，4的条件下可合成较低相对分子质量的中间体癸二酸聚酯二元醇；PPSC弹性体的玻璃化转变温度在0℃以下，于室温及人体温度下处于高弹态；PPSC为适度交联的、低模量高伸长的弹性体，其在37℃、pH值为7.4的磷酸盆缓冲溶液中具有较快的降解性（降解度超过50%）。
