文题释义:
膝骨关节炎:
是临床较常见的退行性关节疾病,随着年龄的增长其发病率增加,临床主要表现为活动障碍与关节疼痛。目前针对膝骨关节炎的治疗主要分为非手术治疗与手术治疗,非手术治疗包括药物治疗、理疗等,虽然这些方法能够暂时缓解膝骨关节炎的临床症状,或是在一定程度上阻滞病情的发展,但是受损的膝关节软骨难以获得完全修复;手术治疗主要包括马赛克整形、软骨下骨钻孔、软骨清理成形等,虽然具有一定的疗效,但是个体差异较大,不能从根本上解决软骨进行性损伤的问题。
Ⅱ型胶原:在胶原家族的众多成员中,Ⅱ型胶原主要分布于软骨、玻璃体内,许多软骨性疾病的发生发展都与Ⅱ型胶原的结构和功能异常密切相关。由软骨细胞分泌的Ⅱ型胶原,是细胞基质的重要组成成分,可以灵敏地反映软骨代谢情况,因此逐渐成为研究膝骨关节炎生物学标志物的重要指标。

 

摘要
背景:
以往研究证实,龙鳖胶囊与骨髓间充质干细胞单独应用均对膝骨关节炎具有一定的治疗作用。
目的:观察龙鳖胶囊联合骨髓间充质干细胞移植修复膝骨关节炎的效果。
方法:将96只成年雄性SD大鼠随机分为4组,分别为造模组、药物组、干细胞组与药物+干细胞组,每组24只。4组均采用膝关节腔注射木瓜蛋白酶的方法复制骨关节炎模型,造模后第3天,干细胞组膝关节腔内注射0.1 mL骨髓间充质干细胞悬液,1次/周;药物组灌胃龙鳖胶囊水溶液0.937 5 g/kg,2次/周;药物+干细胞组膝关节腔内注射0.1 mL骨髓间充质干细胞,1次/周,同时灌胃龙鳖胶囊水溶液0.937 5 g/kg,2次/周,各组连续处理4周。造模前、造模后第3天及给药4周后,ELISA法检测血清白细胞介素1β与白细胞介素6水平;给药4周后,取大鼠右侧膝关节软骨标本,进行苏木精-伊红染色病理观察,同时RT-PCR、Western blot检测Ⅱ型胶原、Hur、XIAP基因及蛋白的表达。
结果与结论:①造模后第3天,各组白细胞介素1β、白细胞介素6水平均较造模前明显升高;给药4周后,造模组白细胞介素1β、白细胞介素6水平明显高于其他3组(P < 0.05),药物组、干细胞组白细胞介素1β、白细胞介素6水平明显高于药物+干细胞组(P < 0.05);②造模组关节软骨组织表面粗糙且破坏严重,裂隙较多,软骨细胞聚集分布且排列混乱;药物组、干细胞组均可见部分软骨修复,软骨组织表面较造模组平整,软骨细胞增多且分布较均匀,裂隙较造模组减少;药物+干细胞组关节软骨组织表面光滑平整,软骨细胞形态规则且排列均匀,无关节裂隙;③造模组Ⅱ型胶原、Hur、XIAP蛋白和基因表达均低于其余3组(P < 0.05);药物组、干细胞组Ⅱ型胶原、Hur、XIAP蛋白和基因表达明显低于药物+干细胞组(P < 0.05);④结果说明,龙鳖胶囊联合骨髓间充质干细胞移植修复膝骨关节炎的效果更优。

Abstract:

BACKGROUND: Previous studies have confirmed that Longbie capsule or bone marrow mesenchymal stem cells alone have a certain therapeutic effect on knee osteoarthritis.
OBJECTIVE: To observe whether Longbie capsule combined with bone marrow mesenchymal stem cell transplantation is better than the single use in the treatment of knee osteoarthritis.
METHODS: Ninety-six adult male Sprague-Dawley rats were randomly divided into four groups: model group, drug group, stem cell group and drug+stem cell group, with 24 rats in each group. Papain was injected into the knee joint cavity of each rat to duplicate the osteoarthritis model. On the 3rd day after modeling, 0.1 mL of bone marrow mesenchymal stem cell suspension was injected into the knee joint cavity of the rats in the stem cell group, once a week; the water solution of Longbie capsule, 0.937 5 g/kg, was intragastrically injected into the rats in the drug group, twice a week; and the above-mentioned treatments were both performed in the drug+stem cell group. The treatment in each group lasted for 4 weeks. The levels of serum interleukin-1β and interleukin-6 were measured using ELISA before modeling, 3 days after modeling and 4 weeks after administration. Four weeks after administration, the cartilage samples were taken from the right knee joint of each rat for pathological observation with hematoxylin-eosin staining, and for detecting the expressions of collagen type II, Hur, XIAP protein and mRNA using RT-PCR and western blot, respectively. 
RESULTS AND CONCLUSION: On the 3rd day after modeling, the levels of interleukin-1β and interleukin-6 in each group were significantly higher than those before modeling. After 4 weeks of administration, the levels of interleukin-1β in the model group were significantly higher than those in the other three groups (P < 0.05); and the levels of interleukin-1β and interleukin-6 in the drug group and stem cell group were significantly higher than those in the drug+stem cell group (P < 0.05). (2) The surface of articular cartilage tissue in the model group was rough and severely damaged, there were many joint fissures, and the chondrocytes were aggregated and distributed in disorder. The damaged cartilage tissues were partially repaired in the drug group and stem cell group, with the smoother surface of cartilage tissue and fewer joint fissures than the model group, and there were also increased and evenly distributed chondrocytes in the former two groups. The surface of articular cartilage in the drug+stem cell group was smooth, and the chondrocytes were regular and uniformly arranged without joint fissures. (3) The expression of type II collagen, Hur, XIAP protein (or gene) in the model group was lower than that in the other three groups (P < 0.05), and the expression of type II collagen, Hur, and XIAP protein (or gene) in the drug group and stem cell group was lower than that in the drug+stem cell group (P < 0.05). These results indicate that Longbie capsule combined with bone marrow mesenchymal stem cell transplantation is superior to Longbie capsule or bone marrow mesenchymal stem cell transplantation used alone in the treatment of knee osteoarthritis.
