"User-centered" is the core concept of library services. Based on the theory of user relation- ship management, the Library of Southeast University carries out the practical exploration of user relationship management, subdivides the user groups, grasps the demand, and establishes the strong interactive relationship with the users through multiple channels, it has achieved good results in the aspects of user participation and user benefit, and it is expected to provide helpful reference to the user services of university libraries.

目的　观察半月板损伤导致的滑膜炎患者滑膜滑液中基质金属蛋白酶３（ＭＭＰ-３）、基质金属蛋白酶９ （ＭＭＰ-９）和基质金属蛋白酶１３（ＭＭＰ-１３）的表达变化。方法　１２８ 例半月板损伤患者，根据是否有伴有滑膜炎分 为半月板损伤诱发滑膜炎者８１ 例（观察组）和单纯半月板损伤者４７ 例（对照组）。分别采用荧光定量ＰＣＲ 法和免 疫组化法检测两组滑膜组织中ＭＭＰ-３、ＭＭＰ-９ 和ＭＭＰ-１３ ｍＲＮＡ 和蛋白，采用ＥＬＩＳＡ 法检测两组滑液ＭＭＰ-３、 ＭＭＰ-９ 和ＭＭＰ-１３。结果　观察组滑膜组织中ＭＭＰ-３、ＭＭＰ-９ 和ＭＭＰ-１３ ｍＲＮＡ 相对表达量分别为３. １２ ± 0. ４１、 ２. １0 ±0. ２４、３. 0１ ±0. ３0，对照组分别为１. ５３ ± 0. ３５、0. ８７ ± 0. １８、１. １２ ± 0. ２１，Ｐ 均＜ 0. 0５；观察组滑膜组织中 ＭＭＰ-３、ＭＭＰ-９ 和ＭＭＰ-１３ 蛋白相对表达量分别为３９４. １ ±２0. ６、１７0. ５ ± １４. ８、１９0. ７ ± １３. ６，对照组分别为２0４. ５ ±１５. ３、９0. ３ ±８. ４、１0９. ３ ±１0. ４，Ｐ 均＜0. 0５。观察组滑液组织中ＭＭＰ-３、ＭＭＰ-９ 和ＭＭＰ-１３ ｍＲＮＡ 相对表达量分 别为１２. ５ ±２. １、１５. ７ ±２. ４、９. ５ ±１. ９，对照组分别为１９. ４ ±２. ６、１７. ５ ±２. ３、１４. ７ ±２. ４，Ｐ 均＜ 0. 0５。观察组Ａｙｒａｌ 滑膜炎评分≤６0 分者滑液ＭＭＰ-３、ＭＭＰ-９ 和ＭＭＰ-１３ 水平明显低于Ａｙｒａｌ 滑膜炎评分＞ ６0 分者（Ｐ ＜ 0. 0５）。结论 　半月板损伤导致的滑膜炎患者滑膜、滑液存在ＭＭＰ-３、ＭＭＰ-９ 和ＭＭＰ-１３ 高表达。ＭＭＰ-３、ＭＭＰ-９ 和ＭＭＰ-１３ 的 异常表达可能与半月板损伤滑膜炎的发生有关。 [ABSTRACT FROM AUTHOR]
