摘要:


文题释义:
大麻二酚(cannabidiol,CBD):是从大麻植物中提取的纯天然成分,大麻二酚可产生消炎镇痛作用,消炎镇痛的药理机制主要与CB1受体和CB2受体有关。CB1受体通过直接抑制中脑导水管周围灰质和RVM内的γ-氨基丁酸(GABA)以及脊髓内谷氨酸的释放来达到镇痛效果。
炎症基因:是参与炎症反应的各种细胞因子,主要有肿瘤坏死因子α、白细胞介素1β、白细胞介素6、转化生长因子β等。

背景:大麻二酚能够有效改善机体的炎症反应,但在改善力竭运动引起的骨骼肌炎症方面,并未有明确的机制研究。
目的:利用转录组学测序技术探究大麻二酚在力竭运动过程中对大鼠骨骼肌炎症的影响机制。
方法:随机将36只SD大鼠分为6组:空白对照组、运动椰子油组、运动对照组、50 mg/kg大麻二酚组、60 mg/kg大麻二酚组、70 mg/kg大麻二酚组,每组6只。除空白对照组大鼠外,其余各组大鼠进行为期9 d的游泳运动制作力竭运动模型。每次游泳运动结束后,大麻二酚组大鼠给予不同浓度(50,60,70 mg/kg)脂溶性大麻二酚2 mL灌胃;运动椰子油组大鼠给予同等体积椰子油灌胃,直至第9天运动结束;空白对照组和运动对照组大鼠不做特殊处理。使用ELISA及转录组测序技术测定不同组大鼠骨骼肌中炎症因子的水平及差异基因,将得到的差异基因进行KEGG分析,并通过荧光定量PCR验证测序数据的准确性。
结果与结论:①ELISA检测结果显示,相比于空白对照组和运动椰子油组,运动对照组中白细胞介素6(P < 0.05)、肿瘤坏死因子α(P < 0.01)、白细胞介素10等质量浓度均增加;经大麻二酚干预后,白细胞介素6、肿瘤坏死因子α质量浓度随大麻二酚浓度的加大而呈现依次递减的趋势;②通过GO和KEGG数据库的比较,对差异基因的功能特性进行分析,结果表明差异基因主要参与肿瘤坏死因子信号通路和Toll样受体信号通路;③RT-qPCR验证结果显示,随机选择5个差异基因的变化趋势与转录组测序结果相一致。结论:大麻二酚能够改善力竭运动引起的骨骼肌炎症反应。

Abstract: BACKGROUND: Cannabidiol is effective in ameliorating the body’s inflammatory response, but no clear mechanistic studies have been conducted to ameliorate skeletal muscle inflammation induced by exhaustive exercise.
OBJECTIVE: To explore the mechanism by which cannabidiol improves skeletal muscle inflammation during exhaustive exercise by using transcriptome sequencing technology. 
METHODS: Thirty-six Sprague-Dawley rats were randomly divided into six groups: blank control group, exercise coconut oil group, exercise control group, 50 mg/kg cannabidiol group, 60 mg/kg cannabidiol group, and 70 mg/kg cannabidiol group, with six rats in each group. Except for rats in the blank control group, rats in each group were subjected to swimming exercise for 9 days to produce the exhaustive exercise model. At the end of each swimming exercise, rats in the cannabidiol groups were given 2 mL of fat-soluble cannabidiol at different concentrations (50, 60, and 70 mg/kg) by gavage; rats in the exercise coconut oil group were given the same volume of coconut oil by gavage until the end of the exercise on the 9th day; and rats in the blank control group and the exercise control group were not given any special treatment. The levels of inflammatory factors and differentially expressed genes in the skeletal muscle of rats in each group were determined using ELISA and transcriptome sequencing techniques. Differentially expressed genes obtained were subjected to KEGG analysis, and the accuracy of the sequencing data was verified by fluorescence quantitative PCR. 
RESULTS AND CONCLUSION: The results of ELISA showed that the contents of interleukin-6 (P < 0.05), tumor necrosis factor-α (P < 0.01), interleukin-10 and other inflammatory factors in the exercise group increased significantly compared with the blank control group and the coconut oil group. After cannabidiol intervention, the mass concentrations of interleukin-6 and tumor necrosis factor-α showed a sequential decrease with increasing cannabidiol concentration. By comparing GO and KEGG databases, the functional properties of differentially expressed genes were analyzed, and the results showed that the differentially expressed genes were mainly involved in the tumor necrosis factor signaling pathway and the Toll-like receptor signaling pathway. RT-qPCR results showed that the trends of five randomly selected differentially expressed genes were in agreement with the transcriptome sequencing results. To conclude, cannabidiol can improve skeletal muscle inflammation caused by exhaustive exercise.
