   Abstract:
   Chemotherapy-induced neuropathic pain is a common dose-limiting side effect of anticancerdrugs but lacks an effective treatment strategy. Scolopendra subspinipes has been used in traditional medicine to treat chronic neuronal diseases. Moreover, pharmacopuncture with S subspinipes (SSP) produces potent analgesia in humans and experimental animals. In this study, we examined the effect of SSP into the ST36 acupoint on oxaliplatin-induced mechanical allodynia in mice. Acupoint treatment with SSP (0.5%/20 μL) significantly decreased mechanical allodynia produced by a single oxaliplatin injection (10mg/kg i.p.), which was completely prevented by acupoint preinjection of lidocaine. Intrathecal treatment with yohimbine (25 μg/5 μL), an α₂-adrenoceptor antagonist, prevented the anti-allodynic effect of SSP. In contrast, a high dose (0.1mg/kg i.p.) ofclonidine,an α₂-adrenoceptor agonist, suppressed oxaliplatin-induced mechanical allodynia butproduced severe side effects including hypotension, bradycardia, and motor impairment. The combination of SSP with a lower dose of clonidine (0.03 mg/kg) produced a comparable analgesic effect without side effects. Collectively, our findings demonstrate that SSP produces an analgesic effect in oxaliplatin-induced pain via neuronal conduction at the acupoint and activation of spinal α₂-adrenoceptors. Moreover, acombination of low-dose clonidine with SSP represents a novel and safe therapeutic strategy for chemotherapy-induced chronic pain.

   Perspective

   SSP can relieve oxaliplatin-induced mechanical allodynia. Moreover, SSP potentiates clonidine-induced anti-allodynia, allowing a lower dose of clonidine with no significant side effects. The combination of SSP and low-dose clonidine might provide a novel strategy for the management of chemotherapy-induced peripheral neuropathy.
