摘要:目的 观察电针对急性期面神经损伤兔细胞因子信号转导抑制因子(SOCS)1、SOCS3蛋白表达的影响,确定其较佳刺激量。方法 将新西兰兔面神經用特制止血钳压榨5 min,损伤长度约2.5 cm,制作面神经损伤模型。实验分为空白组、假手术组、模型组和电针弱、中、强刺激组。电针各组术后1 d予不同刺激量治疗,连续7 d,模型组术后不予任何干预。治疗结束后截取各组受损面神经,采用ABC-ELISA检测介导JAK-STAT负反馈调节SOCS1、SOCS3的蛋白表达。结果 与空白组比较,模型组兔SOCS1、SOCS3蛋白表达增加(P<0.01);与模型组比较,电针弱刺激组SOCS1、SOCS3蛋白表达降低(P<0.01)。结论 面神经损伤急性期电针弱刺激可使SOCS1、SOCS3蛋白表达趋于正常,电针治疗效应不随刺激量的增强而增加。

Abstract: Objective To investigate the effects of different stimulation of electroacupuncture on the protein expressions of SOCS1 and SOCS3 in rabbits with acute facial nerve injury; To determine the better stimulation. Methods New Zealand rabbits were treated with special hemostatic forceps for 5 min, and the length of the lesion was about 2.5 cm. The model of facial nerve injury was induced. The experiment was divided into blank group, sham-operation group, model group, and electoracupuncture weak-, medium-, and strong-stimulation group. The model group received no intervention after surgery. After treatment, the damaged facial nerve of each group was intercepted. The protein expressions of SOCS1 and SOCS3 mediated by negative feedback regulation of JAK-STAT were detected by ABC-ELISA. Results Compared with the blank group, the protein expressions of SOCS1 and SOCS3 in the model group increased (P<0.01). Compared with the model group, the protein expressions of SOCS1 and SOCS3 protein in electroacupuncture weak- stimulation group decreased (P<0.01). Conclusion Electroacupuncture can make SOCS1, SOCS3 protein expressions normal for acute facial nerve injury, and acupuncture treatment effect does not increase with the increase of stimulation.

面神经损伤影响患者的表情运动等生理功能,且影响患者身心健康及生活质量。临床上电针治疗本病疗效较好[1-3]。相关机制研究已深入开展,其中细胞因子信号转导抑制因子(SOCS)家族是JAK-STAT通路最重要的抑制信号因子[4]。有研究发现,SOCS1、SOCS3蛋白与面神经修复密切相关[5-7]。本实验以压榨性损伤模型兔为研究对象,采用ABC-ELISA检测兔面神经组织SOCS1、SOCS3的含量,观察电针不同刺激量对急性期面神经损伤兔SOCS1、SOCS3蛋白表达的影响,为临床应用提供依据。
