摘要:


文题释义:
鹿角胶:是一种传统的中药材,来源于鹿科动物梅花鹿或马鹿的已骨化的鹿角或鹿角盘,通过水煎煮、浓缩制成。此次研究中鹿角胶被用于防治模型大鼠的激素性股骨头坏死,其核心蛋白聚糖能促进骨髓间充质干细胞的增殖与成骨分化,对股骨头坏死具有较好的修复作用。
代谢组学:是一门研究生物样本中小分子代谢物的科学,通过分析生物体内所有代谢物的组成和变化,可以揭示生物体内的代谢途径和网络。此次研究采用粪便代谢组学评估鹿角胶对激素性股骨头坏死模型大鼠粪便代谢物的影响,从而探讨其抗激素性股骨头坏死的多重作用机制。

背景:课题组前期研究表明,鹿角胶中的核心蛋白聚糖可进入骨,促进骨髓间充质干细胞的增殖与成骨分化,对股骨头坏死具有较好的修复作用。
目的:通过粪便非靶向代谢组学方法探讨鹿角胶对大鼠激素性股骨头坏死的治疗作用及潜在机制。
方法:采用随机数字表法将30只SD大鼠随机分为3组:对照组(n=10)右侧臀肌注射生理盐水(每周前3 d注射,连续注射3周),同时给予纯净水灌胃(1次/d,连续灌胃6周);模型组(n=10)右侧臀肌注射甲泼尼龙琥珀酸钠(每周前3 d注射,连续注射3周)建立激素性股骨头坏死模型,同时给予纯净水灌胃(1次/d,连续灌胃6周);鹿角胶组(n=10)同样建立激素性股骨头坏死模型,同时给予鹿角胶灌胃
(1次/d,连续灌胃6周)。灌胃结束后收集盲肠粪便与股骨头,分别进行粪便代谢组学分析与骨组织Micro-CT、苏木精-伊红染色。
结果与结论:①代谢组学分析结果显示,鹿角胶组与模型组相比共233种差异代谢物,具有显著差异和明确注释的代谢物共65个,其中脂质和氨基酸类代谢物含量显著升高,胆酸、硫酸固醇脂、麻黄碱、次黄嘌呤、甜菜碱、左旋肉碱、B-鼠胆酸、胞啶、4-嘧啶酸、牛磺酸、N-乙酰-d-葡萄糖胺、丁酸是影响度最高的几种代谢物(变量权重值VIP > 5),牛磺酸和次牛磺酸的代谢途径在代谢调控网络中的重要性最高(通路影响因子=0.428 57)。②骨组织Micro-CT扫描结果显示模型组与鹿角胶组大鼠股骨头均出现不同程度的损伤,股骨头轮廓欠规整,股骨头软骨下骨中的骨小梁缺失和紊乱,部分可见囊性变结构;与模型组相比,鹿角胶组大鼠骨小梁损伤程度较轻。苏木精-伊红染色结果显示,模型组和鹿角胶组大鼠股骨头软骨下骨的骨小梁稀疏或中断,空骨陷窝率和脂肪细胞侵袭增加;与模型组相比,鹿角胶组大鼠股骨头软骨下骨的空骨陷窝率和脂肪细胞侵袭有所减少。③结果表明,鹿角胶可能通过牛磺酸的代谢过程及相关通路代谢途径发挥防治激素性股骨头坏死的作用。

Abstract: BACKGROUND: Previous studies by the research group have shown that core proteoglycan in Cornus Cervi Colla can enter the bone, promote the proliferation and osteogenic differentiation of bone marrow mesenchymal stem cells, and has a good repair effect on steroid-induced osteonecrosis of the femoral head.
OBJECTIVE: To investigate the therapeutic effect and potential mechanism of Cornus Cervi Colla on steroid-induced osteonecrosis of the femoral head in rats by fecal non-targeted fecal metabolomics. 
METHODS: Thirty SD rats were randomly divided into three groups using a random number table method: the control group (n=10) was injected with normal saline into the right gluteal muscle (injected on the first 3 days of each week for 3 consecutive weeks), and was given pure water gavage (once a day for 6 consecutive weeks). The model group (n=10) was injected with methylprednisolone sodium succinate into the right gluteal muscle (injected on the first 3 days of each week for 3 consecutive weeks) to establish a steroid-induced osteonecrosis of the femoral head model, and was given pure water gavage (once a day for 6 consecutive weeks). The Cornus Cervi Colla group (n=10) was also established with a steroid-induced osteonecrosis of the femoral head model, and was given Cornus Cervi Colla gavage (once a day for 6 consecutive weeks). After gavage, cecal feces and femoral heads were collected for fecal metabolomics analysis and bone tissue Micro-CT and hematoxylin-eosin staining, respectively.
RESULTS AND CONCLUSION: (1) Metabolomics analysis results showed that there were 233 differential metabolites between the Cornus Cervi Colla and model groups, with 65 significantly differing and clearly annotated metabolites. Lipid and amino acid metabolites were significantly increased, with bile acids, sulfated steroids, ephedrine, hypoxanthine, betaine, L-carnitine, B-mouse bile acid, cytidine, 4-pyridoxic acid, taurine, N-acetyl-d-glucosamine, and butyric acid being the most impacted (variable weight value VIP > 5). The metabolic pathways of taurine and hypotaurine were crucial in the metabolic regulatory network (pathway impact=0.428 57). (2) Micro-CT scanning results of bone tissue showed that the femoral heads of rats in the model group and the Cornus Cervi Colla group had different degrees of damage; the femoral head contour was irregular; the trabeculae in the subchondral bone of the femoral head were missing and disordered, and some cystic structures were visible. Compared with the model group, the degree of trabecular damage in the rats of the Cornus Cervi Colla group was milder. Hematoxylin-eosin staining results showed that the trabeculae in the subchondral bone of the femoral heads of rats in the model group and the Cornus Cervi Colla group were sparse or interrupted, and the empty bone lacuna rate and adipocyte invasion were increased. Compared with the model group, the empty bone lacuna rate and adipocyte invasion in the subchondral bone of the femoral heads of rats in the Cornus Cervi Colla group were reduced. (3) These results conclude that Cornus Cervi Colla potentially mitigates steroid-induced osteonecrosis of the femoral head through the metabolic processes involving taurine and associated pathways.
