Abstract

Ethnopharmacological relevance: The Shenqisherong (SQSR) pill is an empirical prescription of traditional Chinese medicine (TCM), which originated from the National Chinese Medical Science Master, Shi Qi. It has been widely used in the treatment of cervical spondylotic myelopathy (CSM) and promote the recovery of spinal cord function, but underlying molecular mechanism remains unclear.

Aim of the study: The objective of this study was to confirm the neuroprotective effects of the SQSR pill.

Materials and methods: A rat model of chronic compression at double-level cervical cord was used in vivo. The protective role of SQSR pill on CSM rats was measured by Basso, Beattie, and Bresnahan (BBB) locomotor scale, inclined plane test, forelimb grip strength assessment, hindlimb pain threshold assessment, and gait analysis. The levels of Reactive Oxygen Species (ROS) were examined by Dihydroethidium (DHE) staining and 2',7'-Dichlorofluorescein (DCF) assay, and Apoptosis was detected by TdT-mediated dUTP nick-end labeling (TUNEL) assay. The expression of Apoptosis proteins was evaluated by immunofluorescence staining and Western blot.

Results: SQSR pill could facilitate locomotor function recovery in rats with chronic cervical cord compression, reduce local ROS in the spinal cord and downregulate the c-Jun-N-terminal kinase (JNK)/Caspase-3 signaling pathway. In addition, the SQSR pill could protect primary rat cortical neurons from glutamate-treated toxicity in vitro by reducing the ROS and downregulating the phosphorylation of JNK and its downstream factors related to neuronal Apoptosis meditated by the Caspase cascade. Then, the neuroprotective effect was counteracted by a JNK Activator.

Conclusions: Together, SQSR pill could ameliorate neuronal Apoptosis by restraining ROS accumulation and inhibiting the JNK/Caspase-3 signaling pathway, indicating that SQSR pill could be a candidate drug for CSM.
