摘要:



文题释义:
线粒体转录因子A(TFAM):是调控线粒体DNA复制和转录的关键因子,直接影响线粒体能量代谢和基因表达,其功能与多种生物学过程密切相关。 ‌
核呼吸因子1(NRF1):是调控线粒体生物合成及氧化应激的关键转录因子,过表达核呼吸因子1可显著抑制细胞凋亡。

背景:氧化应激是造成前交叉韧带损伤后肌萎缩的潜在因素之一。改善骨骼肌疲劳则有利于本体感觉的恢复,从而加速前交叉韧带损伤后的康复进程,而改善线粒体功能有利于缓解骨骼肌疲劳损伤。
目的:验证不同频率电针通过干预骨骼肌氧化应激损伤及线粒体功能改善兔骨骼肌疲劳,恢复本体觉功能,从而加速前交叉韧带损伤后康复。
方法:24只健康新西兰兔随机分为空白组、模型组、低频电针组、高频电针组4组,每组6只。模型组、低频电针组、高频电针组兔构建膝关节前交叉韧带损伤模型,低频电针组、高频电针组兔造模后7 d于造模侧膝关节血海、梁丘穴进行电针治疗,空白组及模型组兔仅抓取、固定,不进行电针干预,每天治疗1次,连续治疗21 d。干预结束后用ELISA检测股四头肌中的超氧化物歧化酶、琥珀酸脱氢酶、丙二醛水平;蛋白印迹法检测兔骨骼肌组织中沉默信息调节因子2相关酶1、过氧化物酶体增殖物激活受体γ辅助激活物1α、线粒体转录因子A蛋白的表达水平,以及沉默信息调节因子2相关酶1、过氧化物酶体增殖物激活受体γ辅助激活物1α、核呼吸因子1和线粒体转录因子A的mRNA表达情况。
结果与结论:前交叉韧带损伤后兔股四头肌超氧化物歧化酶水平上升,琥珀酸脱氢酶水平下降、丙二醛浓度上升;沉默信息调节因子2相关酶1、过氧化物酶体增殖物激活受体γ辅助激活物1α、线粒体转录因子A蛋白表达下降;沉默信息调节因子2相关酶1、过氧化物酶体增殖物激活受体γ辅助激活物1α、核呼吸因子1和线粒体转录因子A的mRNA表达均显著下调;电针干预后,兔患侧股四头肌中的丙二醛浓度减少,超氧化物歧化酶、琥珀酸脱氢酶活性上升,沉默信息调节因子2相关酶1、过氧化物酶体增殖物激活受体γ辅助激活物1α、线粒体转录因子A蛋白表达上升;沉默信息调节因子2相关酶1、过氧化物酶体增殖物激活受体γ辅助激活物1α、核呼吸因子1和线粒体转录因子A等线粒体生物发生相关基因的mRNA表达上升,且低频电针组优于高频电针组。结果说明,电针可通过调高超氧化物歧化酶、琥珀酸脱氢酶含量,并降低丙二醛含量,减轻前交叉韧带损伤后骨骼肌氧化应激损害;并通过调控沉默信息调节因子2相关酶1/过氧化物酶体增殖物激活受体γ辅助激活物1α信号通路相关蛋白及线粒体生物发生相关基因的表达改善线粒体功能,加速前交叉韧带损伤后康复。

Abstract: BACKGROUND: Oxidative stress is one of the potential factors contributing to muscle atrophy following anterior cruciate ligament injury. Alleviating skeletal muscle fatigue facilitates proprioceptive recovery, thereby accelerating rehabilitation after anterior cruciate ligament injury. Improving mitochondrial function helps mitigate skeletal muscle fatigue-related damage.
OBJECTIVE: To verify that electroacupuncture at different frequencies alleviates skeletal muscle oxidative stress damage and improves mitochondrial function in rabbits, thereby reducing skeletal muscle fatigue, restoring proprioceptive function, and accelerating rehabilitation following anterior cruciate ligament injury.
METHODS: Twenty-four healthy New Zealand rabbits were randomly divided into blank group, model group, low-frequency electroacupuncture group and high-frequency electroacupuncture group, with six rabbits in each group. The model group, low-frequency electroacupuncture group and high-frequency electroacupuncture group were used to establish the anterior cruciate ligament injury model of the knee joint. The low-frequency electroacupuncture group and high-frequency electroacupuncture group were treated with electroacupuncture at the Xuehai and Liangqiu acupoints on the injured side of the knee joint 7 days after modeling, while the blank and model groups were only grasped and fixed without electroacupuncture intervention. The treatment was continued for 21 days. After the intervention, the contents of superoxide dismutase, succinate dehydrogenase, malondialdehyde in the quadriceps femoris were detected by ELISA; the expression levels of silent information regulator 2-related enzyme 1, peroxisome proliferator-activated receptor gamma coactivator 1α, and mitochondrial transcription factor A proteins in the skeletal muscle tissue of rabbits and the mRNA expression levels of silent information regulator 2-related enzyme 1, peroxisome proliferator-activated receptor gamma coactivator 1α, nuclear respiratory factor 1, and mitochondrial transcription factor A were detected by western blot assay.
RESULTS AND CONCLUSION: After anterior cruciate ligament injury, the expression level of superoxide dismutase in the quadriceps femoris of rabbits increased, the expression level of succinate dehydrogenase decreased, and the expression level of malondialdehyde increased; the expression levels of silent information regulator 2-related enzyme 1, peroxisome proliferator-activated receptor gamma coactivator 1α, and mitochondrial transcription factor A proteins decreased; the mRNA expression levels of silent information regulator 2-related enzyme 1, peroxisome proliferator-activated receptor gamma coactivator 1α, nuclear respiratory factor 1, and mitochondrial transcription factor A were significantly down-regulated. After electroacupuncture intervention, the expression of malondialdehyde in the quadriceps femoris on the injured side decreased, the activities of superoxide dismutase and succinate dehydrogenase increased, the expression levels of silent information regulator 2-related enzyme 1, peroxisome proliferator-activated receptor gamma coactivator 1α, and mitochondrial transcription factor A proteins increased; the mRNA expression levels of silent information regulator 2-related enzyme 1, peroxisome proliferator-activated receptor gamma coactivator 1α, nuclear respiratory factor 1, and mitochondrial transcription factor A, which are related to mitochondrial biogenesis, increased, and the low-frequency electroacupuncture group was superior to the high-frequency electroacupuncture group. To conclude, electroacupuncture can reduce oxidative stress damage in skeletal muscle after anterior cruciate ligament injury by increasing the levels of superoxide dismutase and succinate dehydrogenase and reducing the content of malondialdehyde; and improve mitochondrial function by regulating the expression of silent information regulator 2-related enzyme 1/peroxisome proliferator-activated receptor gamma coactivator 1α signaling pathway-related proteins and regulating the mRNA expression levels of genes related to mitochondrial biogenesis, thereby accelerating the recovery after anterior cruciate ligament injury.
