周围神经损伤是临床常见问题[1],尽管目前周围神经修复技术已经有了很显著的进步,但即使新鲜、清洁的周围神经断裂伤,能及时运用显微外科技术进行修复,也往往不能完全再生,患者神经功能恢复不能令人满意[2].因此,如何促进周围神经损伤后的再生,恢复其功能已日益成为相关研究的重点.
Treatment of peripheral nerve injury is a major challenge in clinical practice. With advances in molecular biology and development of mierosurgieal techniques and tissue engineering, peripheral nerve repair procedures have been greatly improved. In the last 10 decades, most treatments for peripheral nerve injury in animal models have achieved histological and functional recovery, the treatments in humans, however, produce insufficient recovery, especially for proximal nerve injury. Increasing attention has been paid to the Traditional Chinese Medicine (TCM) for promoting peripheral nerve regeneration, since these remedies often display effective clinical outcome, minor side effects and effectiveness for multiple targets. Although TCM has complex ingredients and the specific pharmacological mechanisms for their effectiveness are still unclear, an effective clinical outcome is welcomed by many clinicians. In the past 20 years, we have made a series of detailed studies including the toxicity tests, pharmacodynamic tests, pharmacological experiments etc, about a new traditional formula which mainly contains the Radix hedysari, Epimedium etc, Results have shown that this formula is safe to be used in both animals and hu- mans with no toxicity and adverse effect, and systemic administration of this formula could enhance the peripheral nerve regeneration.
