【摘要】：目的:通過檢測大鼠脊髓損傷(SCI)后運動功能恢復情況和腦源性神經生長因子(BDNF)、神經軸突生長抑制劑-A(Nogo-A)的表達來探討聯合應用督脈電針和超短波療法對SCI的作用機制。方法:復制并評價脊髓全橫斷損傷大鼠模型,100只雌性大鼠隨機分為5組:假手術組、SCI組、SCI+督脈電針組、SCI+超短波組、SCI+督脈電針+超短波組(n=20),檢測各組7d、14d、21d、28d這4個時間點BDNF和Nogo-A表達,對各組大鼠進行BBB評分。結果:與模型組相比,各治療組的BBB評分顯著增加,聯合組在術后第7d、14d、21d、28d較超短波組和督電組BBB評分顯著增加,具有顯著性差異(P0.01)。與模型組相比,各治療組BDNF的表達均顯著增加,Nogo-A的表達均顯著減少,聯合組在術后第7d、14d、21d、28d較超短波組和督電組BDNF的表達顯著增加,Nogo-A的表達顯著減少,具有顯著性差異(P0.01)。結論:(1)聯合應用督脈電針與超短波治療,能夠提高SCI后BDNF的表達及抑制Nogo-A的表達來促進神經的修復。(2)聯合療法對大鼠運動功能恢復更佳。
[Abstract]:Aim: to investigate the mechanism of combined use of du meridian electroacupuncture and ultrashort wave therapy in detecting the recovery of motor function after spinal cord injury (SCI) and the expression of brain-derived nerve growth factor (BDNF),) nerve axon growth inhibitor -A (Nogo-A) in rats with spinal cord injury (sci). Methods: a total of 100 female rats with spinal cord transection injury were randomly divided into five groups: sham operation group (sci group), sci du pulse electroacupuncture group (sci ultrashort wave group), sci supernatant pulse electroacupuncture (sci) ultrashort wave group (n = 20), and the expression of BDNF and Nogo-A at four time points (7 d, 14 d, 21 d, 28 d). BBB score was performed on each group of rats. Results: compared with the model group, the BBB score of each treatment group was significantly increased, and the BBB score of the combined group was significantly higher than that of the ultrashort wave group and the governor group on the 7th day, 14d, 21d and 28d after operation (P0.01). Compared with the model group, the expression of BDNF in each treatment group was significantly increased and the expression of Nogo-A was significantly decreased in the combined group. The expression of BDNF in the combined group was significantly lower than that in the ultrashort wave group and the control group on the 14th day and 21st day after operation (P0.01). Conclusion: (1) combined therapy of du meridian electroacupuncture and ultrashort wave can increase the expression of BDNF and inhibit the expression of Nogo-A after SCI to promote nerve repair. (2) the combined therapy can improve the recovery of motor function in rats.
