文题释义:
离心运动:运动时骨骼肌进行收缩,在产生张力的同时起止点相互远离被迫拉长,这种运动方式被称为离心运动,也被称为退让工作,在运动的过程中肌肉做负功,一些情况下离心运动方式可以起到保护作用,例如高处下跳时股四头肌的离心收缩。
白细胞介素6:一种糖基化蛋白,相对分子质量在22 000-27 000,带28个信号序列,作为一种细胞因子具有较多的生物学功能,能够刺激细胞生长、促进细胞增殖分化、协同其他因子发挥作用等,其来源广泛包括骨骼肌细胞、中性粒细胞、T细胞、B细胞、造骨细胞等众多类型细胞。
摘要
背景
:白细胞介素6是一种细胞因子,其来源广泛,在运动后骨骼肌能够大量产生并对运动功能恢复起到重要作用;运动后进行骨骼肌针刺能够改善骨骼肌的超微结构,降低损伤程度,促进功能恢复。目前尚未见到针刺对运动后白细胞介素6影响的报道。
目的:探究针刺干预对一次离心运动后大鼠白细胞介素6的影响。
方法:114只雄性SD大鼠,随机分为:安静对照组(n=6)、单纯运动组(n=36)、单纯针刺组(n=36)、运动针刺组(n=36)。单纯运动组和运动针刺组均在坡度-16°的跑台上进行一次离心运动,单纯针刺组和运动针刺组进行小腿三头肌的斜刺。各组处理后,除安静组直接取材,其余3组分别在干预后0,2,24,48,72,120 h时间点取材,每个时间点6只。Western Blot法分别检测比目鱼肌、股直肌白细胞介素6的蛋白表达;ELISA法检测血浆中白细胞介素6水平。
结果与结论:①单纯针刺处理后,比目鱼肌和股直肌中白细胞介素6蛋白表达以及血浆中白细胞介素6水平均无明显变化(P > 0.05);②一次离心运动后,比目鱼肌、股直肌和血浆中白细胞介素6均出现不同程度升高,且比目鱼肌与股直肌间白细胞介素6表达无明显差异(P > 0.05);③运动后针刺能明显下调比目鱼肌白细胞介素6蛋白峰值表达(P < 0.05),而股直肌和血浆中白细胞介素6表达无明显变化(P > 0.05);④结果表明,对骨骼肌进行直接针刺干预不能引起白细胞介素6明显变化,骨骼肌在离心运动后会分泌较多的白细胞介素6,同时进行针刺干预能够降低针刺部位白细胞介素6的峰值量;针刺能够在局部对白细胞介素6产生明显作用,对于其他部位的骨骼肌和血浆未能产生显著效果。

Abstract:

BACKGROUND: Interleukin-6, is a cytokine that has wide sources. Interleukin-6 increases in the skeletal muscle after exercise, which plays an important role in motor function recovery. Acupuncture at the skeletal muscle after exercise can improve the ultrastructure of skeletal mscle, alleviate injury and promote functional recovery. However, acupuncture effects on the interleukin-6 post exercise remains unknown.
OBJECTIVE: To explore the influence of acupuncture intervention on interleukin-6 in rats after eccentric exercise.
METHODS: Totally 114 male Sprague-Dawley rats were randomly divided into four groups: control group (n=6), exercise group (n=36), acupuncture group (n=36) and exercise plus acupuncture group (n=36). The rats in the exercise and exercise plus acupuncture groups were submitted to eccentric exercise on a downward treadmill at 16° decline. The rats in the acupuncture and exercise plus acupuncture groups were subjected to the oblique acupuncture at the triceps surae. Samples except the control group were collected at 0, 2, 24, 48, 72 and 120 hours after treatment (n=6 per group at each time point). Protein expression level of interleukin-6 in the soleus and rectus femoris was detected by western blot assay. The plasma level of interleukin-6 was determined by ELISA.
RESULTS AND CONCLUSION: In the acupuncture group, the protein expression level of interleukin-6 in the soleus and rectus femoris and plasma level of interleukin-6 showed no significant changes (P > 0.05). After eccentric exercise, the interleukin-6 levels in the soleus, rectus femoris and plasma were significantly increased, and the protein expression level of interleukin-6 did not differ significantly between soleus and rectus femoris (P > 0.05). Acupuncture intervention after exercise, the protein expression level of interleukin-6 in the soleus was significantly reduced (P < 0.05), while interleukin-6 levels in the rectus femoris and plasma showed no significant change (P > 0.05). These findings imply that acupuncture cannot markedly change the interleukin-6 level in normal rats. Eccentric exercise can lead skeletal muscle to create more interleukin-6, and acupuncture intervention after eccentric exercise can reduce the amount of interleukin-6 at peak phase in the needling part. But its effect is local, not significant on the skeletal muscle of other parts and plasma.
