Objective:To elucidate the mechanism of Chinese tuina in treating sciatic nerve crush injury,and to detect the levels of tissue plasminogen activator(t PA)and plasminogen activator inhibitor-1(PAI-1),which is thought to play an important role in nerve regeneration.Methods:Thirty-two adult male Sprague-Dawley rats were subjected to sciatic nerve crush injury and 16 rats(sham-operated group)went through a sham operation.Control group was given no treatment while tuina group received tuina therapy since day 7 post-surgery.Tuina treatment was performed once a day and lasted for 20 days.The sciatic functional index was examined every 5days during the treatment session.The rats’gastrocnemius muscles were evaluated for changes in mass and immunohistochemistry techniques were performed to detect the levels of tP A and PAI-1.Results:Tuina therapy improved the motor function of sciatic nerve injured rats(P<0.05),however,it did not increase muscle volume(P<0.05).Tuina downregulated the levels of t PA and PAI-1(P<0.05).Conclusions:The present study implies that tuina treatment could accelerate rehabilitation of peripheral nerve injury.

Methods: Thirty-two adult male Sprague-Dawley rats were subjected to sciatic nerve crush injury and 16 rats (sham-operated group) went through a sham operation. Control group was given no treatment while tuina group received tuina therapy since day 7 post-surgery. Duina treatment was performed once a day and lasted for 20 days. The sciatic functional index was examined every 5 days in the treatment session. Rats’ gastrocnemius muscles were evaluated for changes in mass and immunohistochemistry techniques were performed to detect the Levels of tP A and PAI-1.Results: Tuina therapy improved the motor function of sciatic nerve injured rats (P <0.05), however, it did not increase muscle volume (P <0.05). Tuina downregulated the levels of t PA and PAI-1 (P <0.05) .Conclusions: The present study implies that tuina treatment could accelerate rehabilitation of peripheral nerve injury.
