The sprouts from endplate and a few contact sites of NCAM with AChR can be seen.C: Untreated group on the 20th day after L5 nerve root compression. There are some AChR plaques of morphological abnormality, and no contact sites of NCAM with AChR although the intensity and scope of NCAM staining is increased.D: Yiqi Huayu Recipetreated group on the 20th day after L5 nerve root compression. All the AChR sites are reoccupied by NCAM and the morphology of AChR are restored. E: Untreated group on the 30th day after lumbar nerve root compression. AChR plaques display irregularity in shape, with a few round or spindle shaped cupulae. Meanwhile, some NCAM stainings are still shown to be around the AChR. F: Yiqi Huayu Recipetreated group on the 30th day after L5 nerve root compression.

随着时间的推移，AChR斑的形态渐趋规则，NCAM反应也逐步增强，至造模后20 d达到最高峰，但益气化瘀方组仍然明显优于模型组，其不仅在数值上超过了胚胎期大鼠，且与AChR全部重叠；而模型组仍可见到不少重叠不全且形态异常的AChR斑。L5神经根受压后30 d，NCAM的表达水平开始下降，基本局限于终板区内，其下降速度和范围在益气化瘀方组明显大于模型组；模型组不仅NCAM的表达明显高于益气化瘀方组，且仍能见到一些成熟不全的AChR斑；而益气化瘀方组AChR斑形态已接近于正常。
