摘要:


文题释义:
人来源软骨细胞:从人体软骨中获得的细胞,呈圆形或多角形,与人体软骨组织有着相同的生理功能,体外培养的人软骨细胞是用于膝骨关节炎软骨修复研究的关键细胞。
淫羊藿苷含药血清:淫羊藿是补肾壮阳之要药,淫羊藿苷是淫羊藿的主要有效活性单体,动物连续灌胃淫羊藿苷溶液后,采集血液并分离得到血清,即为淫羊藿苷含药血清。

背景:课题组前期研究发现,淫羊藿苷含药血清能够延缓大鼠膝骨关节炎进展,促进软骨细胞增殖与干细胞成软骨分化,但是否能应用于临床尚缺乏充分依据。
目的:探讨淫羊藿苷含药血清对脂多糖诱导的人软骨细胞炎症损伤的修复效应。
方法:CCK-8法检测淫羊藿苷含药血清对人软骨细胞活力的影响并筛选出最佳的淫羊藿苷含药血清体积分数及干预时间;然后将人软骨细胞分为空白对照组、脂多糖组、淫羊藿苷含药血清组及脂多糖+淫羊藿苷含药血清组,按上述分组予以处理后,免疫荧光法检测各组软骨细胞Ⅱ型胶原分泌情况;实时荧光定量PCR法检测相关基因表达。
结果与结论:①淫羊藿苷含药血清对人软骨细胞呈现出良好的生物安全性,当淫羊藿苷含药血清体积分数为15%、干预48 h时细胞活力达最高水平,以此条件为标准进行后续实验;②与空白对照组相比,脂多糖显著抑制软骨细胞分泌Ⅱ型胶原,而淫羊藿苷含药血清能有效促进正常和炎症状态下软骨细胞分泌Ⅱ型胶原;③在脂多糖刺激下,软骨细胞的Ⅱ型胶原和聚蛋白聚糖mRNA表达显著降低,基质金属蛋白酶13、血小板反应蛋白解整合素金属肽酶5 mRNA表达显著升高;淫羊藿苷含药血清能促进炎症状态下软骨细胞Ⅱ型胶原mRNA表达,抑制基质金属蛋白酶13、血小板反应蛋白解整合素金属肽酶5 mRNA表达。结果表明,淫羊藿苷含药血清对人软骨细胞具有良好的安全性,在维持软骨细胞正常生理功能、促进细胞外基质合成和抑制炎症因子分泌方面发挥重要作用。

Abstract: BACKGROUND: Previous studies of the research group have found that icariin-containing serum can delay the progression of knee osteoarthritis, promote chondrocyte proliferation and stem cell cartilage differentiation in rats, but there is still a lack of sufficient basis for clinical application. 
OBJECTIVE: To investigate the repair effect of icariin-containing serum on lipopolysaccharide-induced inflammatory damage of human chondrocytes. 
METHODS: The effect of icariin-containing serum on chondrocyte viability was detected by cell counting kit-8 method, and the optimal volume fraction and time of icariin-containing serum were screened. The cells were then divided into blank group, lipopolysaccharide group, icariin-containing serum group and lipopolysaccharide+icariin-containing serum group. After grouping, immunofluorescence was used to detect the secretion of type II collagen in chondrocytes in each group. Real-time PCR was used to detect the expression of related genes. 
RESULTS AND CONCLUSION: (1) Icariin-containing serum showed good biosafety characteristics for human chondrocytes, and the cell viability reached the highest level after 48 hours of intervention when the icariin-containing serum volume fraction was 15%, and the follow-up experiments were carried out according to the conditions. (2) Compared with the blank group, lipopolysaccharide significantly inhibited the expression of type II collagen in chondrocytes, while icariin-containing serum showed a positive mobilization effect, which could effectively promote the secretion of type II collagen in chondrocytes under normal and inflammatory conditions. (3) The mRNA expression of type II collagen and Aggrecan in chondrocytes decreased significantly under lipopolysaccharide stimulation, and the mRNA expression levels of matrix metalloproteinase 13 and a disintegrin-like and metalloproteinase with thrombospondin motifs-5 increased significantly. Icariin-containing serum promoted the mRNA expression of type II collagen in human chondrocytes under inflammatory conditions and reduced the mRNA expression of matrix metalloproteinase 13 and a disintegrin-like and metalloproteinase with thrombospondin motifs-5 in chondrocytes after lipopolysaccharide intervention. Therefore, these findings indicate that the icariin-containing serum has good safety for human chondrocytes and plays an important role in maintaining the normal physiological functions of chondrocytes, promoting the synthesis of extracellular matrix, and inhibiting the secretion of inflammatory factors.
