Abstract
STUDY DESIGN Basic science study using a hemisection spinal cord injury (SCI) model. OBJECTIVE We sought to assess the effect of blocking osteopontin (OPN) upregulation on motor function recovery and pain behavior after SCI and to further investigate the possible downstream target of OPN in the injured spinal cord. SUMMARY OF BACKGROUND DATA OPN is a noncollagenous extracellular matrix protein widely expressed across different tissues. Its expression substantially increases following SCI. A previous study suggested that this protein might contribute to locomotor function recovery after SCI. However, its neuroprotective potential was not fully explored, nor were the underlying mechanisms. MATERIALS AND METHODS We constructed a SCI mouse model and analyzed the expression of OPN at different time points and the particular cell distribution in the injured spinal cord. Then, we blocked OPN upregulation with lentivirus-delivering siRNA targeting OPN specifically and examined its effect on motor function impairment and neuropathic pain after SCI. The underlying mechanisms were explored in the OPN-knockdown mice model and cultured vascular endothelial cells. RESULTS The proteome study revealed that OPN was the most dramatically increased protein following SCI. OPN in the spinal cord was significantly increased three weeks after SCI. Suppressing OPN upregulation through siRNA exacerbated motor function impairment and neuropathic pain. In addition, SCI resulted in an increase in vascular endothelial growth factor (VEGF), AKT phosphorylation, and angiogenesis within the spinal cord, all of which were curbed by OPN reduction. Similarly, OPN knockdown suppressed VEGF expression, AKT phosphorylation, cell migration, invasion, and angiogenesis in cultured vascular endothelial cells. CONCLUSION OPN demonstrates a protective influence against motor function impairment and neuropathic pain following SCI. This phenomenon may result from the proangiogenetic effect of OPN, possibly due to activation of the VEGF and/or AKT pathways.

Abstract
BACKGROUND Targeted muscle reinnervation (TMR) is an effective technique for the prevention and management of phantom limb pain (PLP) and residual limb pain (RLP) among amputees. The purpose of this study was to evaluate symptomatic neuroma recurrence and neuropathic pain outcomes between cohorts undergoing TMR at the time of amputation (ie, acute) versus TMR following symptomatic neuroma formation (ie, delayed). METHODS A cross-sectional, retrospective chart review was conducted using patients undergoing TMR between 2015 and 2020. Symptomatic neuroma recurrence and surgical complications were collected. A subanalysis was conducted for patients who completed Patient-Reported Outcome Measurement Information System (PROMIS) pain intensity, interference, and behavior scales and an 11-point numeric rating scale (NRS) form. RESULTS A total of 105 limbs from 103 patients were identified, with 73 acute TMR limbs and 32 delayed TMR limbs. Nineteen percent of the delayed TMR group had symptomatic neuromas recur in the distribution of original TMR compared with 1% of the acute TMR group ( P < 0.05). Pain surveys were completed at final follow-up by 85% of patients in the acute TMR group and 69% of patients in the delayed TMR group. Of this subanalysis, acute TMR patients reported significantly lower PLP PROMIS pain interference ( P < 0.05), RLP PROMIS pain intensity ( P < 0.05), and RLP PROMIS pain interference ( P < 0.05) scores in comparison to the delayed group. CONCLUSIONS Patients who underwent acute TMR reported improved pain scores and a decreased rate of neuroma formation compared with TMR performed in a delayed fashion. These results highlight the promising role of TMR in the prevention of neuropathic pain and neuroma formation at the time of amputation. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, III.

Abstract
BACKGROUND The primary objective of this study was to characterize the pharmacological and behavioral activity of 2 novel compounds, DM497 [(E)-3-(thiophen-2-yl)- N -(p-tolyl)acrylamide] and DM490 [(E)-3-(furan-2-yl)- N -methyl- N -(p-tolyl)acrylamide], structural derivatives of PAM-2, a positive allosteric modulator of the α7 nicotinic acetylcholine receptor (nAChR). METHODS A mouse model of oxaliplatin-induced neuropathic pain (2.4 mg/kg, 10 injections) was used to test the pain-relieving properties of DM497 and DM490. To assess possible mechanisms of action, the activity of these compounds was determined at heterologously expressed α7 and α9α10 nAChRs, and voltage-gated N-type calcium channel (Ca V 2.2) using electrophysiological techniques. RESULTS Cold plate tests indicated that 10 mg/kg DM497 was able to decrease neuropathic pain in mice induced by the chemotherapeutic agent oxaliplatin. In contrast, DM490 induced neither pro- nor antinociceptive activity but inhibited DM497's effect at equivalent dose (30 mg/kg). These effects are not a product of changes in motor coordination or locomotor activity. At α7 nAChRs, DM497 potentiated whereas DM490 inhibited its activity. In addition, DM490 antagonized the α9α10 nAChR with >8-fold higher potency than that for DM497. In contrast, DM497 and DM490 had minimal inhibitory activity at the Ca V 2.2 channel. Considering that DM497 did not increase the mouse exploratory activity, an indirect anxiolytic mechanism was not responsible for the observed antineuropathic effect. CONCLUSIONS The antinociceptive activity of DM497 and the concomitant inhibitory effect of DM490 are mediated by opposing modulatory mechanisms on the α7 nAChR, whereas the involvement of other possible nociception targets such as the α9α10 nAChR and Ca V 2.2 channel can be ruled out.

Abstract
AIMS Mitragynine (MG) is an alkaloid found in Mitragyna speciosa (kratom), a plant used to self-treat symptoms of opioid withdrawal and pain. Kratom products are commonly used in combination with cannabis, with the self-treatment of pain being a primary motivator of use. Both cannabinoids and kratom alkaloids have been characterized to alleviate symptoms in preclinical models of neuropathic pain such as chemotherapy-induced peripheral neuropathy (CIPN). However, the potential involvement of cannabinoid mechanisms in MG's efficacy in a rodent model of CIPN have yet to be explored. MAIN METHODS Prevention of oxaliplatin-induced mechanical hypersensitivity and formalin-induced nociception were assessed following intraperitoneal administration of MG and CB1, CB2, or TRPV1 antagonists in wildtype and cannabinoid receptor knockout mice. The effects of oxaliplatin and MG exposure on the spinal cord endocannabinoid lipidome was assessed by HPLC-MS/MS. KEY FINDINGS The efficacy of MG on oxaliplatin-induced mechanical hypersensitivity was partially attenuated upon genetic deletion of cannabinoid receptors, and completely blocked upon pharmacological inhibition of CB1, CB2, and TRPV1 channels. This cannabinoid involvement was found to be selective to a model of neuropathic pain, with minimal effects on MG-induced antinociception in a model of formalin-induced pain. Oxaliplatin was found to selectively disrupt the endocannabinoid lipidome in the spinal cord, which was prevented by repeated MG exposure. SIGNIFICANCE Our findings suggest that cannabinoid mechanisms contribute to the therapeutic efficacy of the kratom alkaloid MG in a model of CIPN, which may result in increased therapeutic efficacy when co-administered with cannabinoids.

Abstract
This study aimed to assess the efficacy of ethanolic extract of Solanum torvum L. fruit (EESTF) containing solasodine in treating chronic constriction injury (CCI)-induced neuropathic pain in rats. Three-dimensional (3D) simulation studies of solasodine binding were conducted on the TRPV1 receptor, IL-6, and TNF-α structures. For in vivo justification, an assessment of behavioral, biochemical, and histological changes was designed after a CCI-induced neuropathic pain model in rats. On days 7, 14, and 21, CCI significantly increased mechanical, thermal, and cold allodynia while producing a functional deficit. IL-6, TNF-α, TBARS, and MPO levels also increased. SOD levels of catalase and reduced glutathione levels also decreased. Administration of pregabalin (30 mg/kg, oral), solasodine (25 mg/kg, oral), and EESTF (100 and 300 mg/kg, oral) significantly reduced CCI-induced behavioral and biochemical changes (P < 0.05). The protective nature of EESTF was also confirmed by histological analysis. Capsaicin, a TRPV1 receptor agonist, abolished the antinociceptive effects of EESTF when used previously. From the observations of the docking studies, solasodine acted as an antagonist at TRPV1, whereas the docking scores of solasodine against TNF-α and IL-6 were reported to be -11.2 and -6.04 kcal/mol, respectively. The attenuating effect of EESTF might be related to its antagonistic effects on TRPV1, suppression of cytokines, and anti-inflammatory and antioxidant properties.

Abstract
ABSTRACT Animal and human studies have shown that exercise prior to nerve injury prevents later chronic pain, but the mechanisms of such preconditioning remain elusive. Given that exercise acutely increases the formation of free radicals, triggering antioxidant compensation, we hypothesized that voluntary running preconditioning would attenuate neuropathic pain by supporting redox homeostasis after sciatic nerve injury in male and female rats. We show that 6 weeks of voluntary wheel running suppresses neuropathic pain development induced by chronic constriction injury across both sexes. This attenuation was associated with reduced nitrotyrosine immunoreactivity-a marker for peroxynitrite-at the sciatic nerve injury site. Our data suggest that prior voluntary wheel running does not reduce the production of peroxynitrite precursors, as expression levels of inducible nitric oxide synthase and NADPH oxidase 2 were unchanged. Instead, voluntary wheel running increased superoxide scavenging by elevating expression of superoxide dismutases 1 and 2. Prevention of neuropathic pain was further associated with the activation of the master transcriptional regulator of the antioxidant response, nuclear factor E2-related factor 2 (Nrf2). Six weeks of prior voluntary wheel running increased Nrf2 nuclear translocation at the sciatic nerve injury site; in contrast, 3 weeks of prior wheel running, which failed to prevent neuropathic pain, had no effect on Nrf2 nuclear translocation. The protective effects of prior voluntary wheel running were mediated by Nrf2, as suppression was abolished across both sexes when Nrf2 activation was blocked during the 6-week running phase. This study provides insight into the mechanisms by which physical activity may prevent neuropathic pain. Preconditioning by voluntary wheel running, terminated prior to nerve injury, suppresses later neuropathic pain in both sexes, and it is modulated through the activation of Nrf2-antioxidant signaling.

Abstract
INTRODUCTION Neuralgia due to a peripheral nerve injury may result in chronic pain, requiring a therapeutic surgical neurectomy. Meanwhile, some neurectomies are performed prophylactically, such as during inguinal mesh removal. Outcomes and risks associated with neurectomies are largely unknown despite consensus panels recommending them. METHODS All patients who underwent neurectomy 2013-2020 were analyzed. Data collection included demographics, preoperative symptoms, and postoperative outcomes. Indications for neurectomy were categorized as "therapeutic" if the patient had preoperative neuralgia or "prophylactic" if neurectomy was deemed necessary intra-operatively. RESULTS 66 patients underwent 80 operations and a total of 122 neurectomies. On average, 1.5 neurectomies were performed per operation. Therapeutic neurectomies were performed in 42 (64%) patients and prophylactic in 34 (52%). The most commonly transected nerve was the ilioinguinal nerve. Average preoperative pain score was 5.8/10. On paired analysis, there was a significant reduction in pain after prophylactic neurectomy (2.5 points, p = 0.002) but not after therapeutic neurectomy. None of the nerves transected prophylactically had postoperative neuralgia, whereas 35% of the nerves transected therapeutically resulted in persistent or recurrent neuralgia (p < 0.001). To treat this, 21% required only nerve blocks and 9% required ablation or reoperative neurectomy. Three patients had complex regional pain syndrome (CRPS), a severe complication; all three were diagnosed with chronic pain syndrome pre-operatively. DISCUSSION We demonstrate that prophylactic neurectomy is largely safe. In contrast, a therapeutic neurectomy had a 35% risk of persistent or recurrent neuralgia, 9% required additional ablative or reoperative neurectomy. Three patients advanced from chronic pain syndrome to CRPS. We recommend the decision to perform a neurectomy be judicious and selective, especially in patients with known chronic pain syndrome. Prior to planning surgical neurectomy, other less invasive modalities should be exhausted and patients should be aware of its risks.

Abstract
Oxaliplatin (OXA) is a key platinum-based chemotherapeutic agent for treatment of metastatic colorectal cancer, but the side effects of acute and chronic neuropathies limit its clinical application. Duloxetine has been found to have the potential to prevent OXA-induced peripheral neuropathy in several studies, but the underlying mechanisms remain unclear. The purpose of this study was to evaluate the effects of duloxetine on OXA-induced peripheral neuropathy and to find the potential mechanisms. The neuropathic pain mice model was used to explore the role of duloxetine on OXA-induced peripheral neuropathy by measuring the change of thermal withdrawal latency (TWL), paw withdrawal threshold (PWT), and intraepidermal nerve fiber density (IENFD). Moreover, to explore molecular mechanisms, effects of duloxetine on OXA-induced changes in mRNA and protein expression of components of the p53-related pathways in cultured rat dorsal root ganglion (DRG) neurons were measured. In vivo, we found duloxetine treatment could significantly prevent the changes in the TWL, PWT to mechanical stimulation, and the IENFD of mice caused by OXA. In vitro, we found duloxetine notably inhibits the relative mRNA and protein expression levels of p53, Bax/Bcl2, caspase-3, and caspase-9 in DRG neurons, which may indicate duloxetine protected the DRG neuron by inhibiting p53-related pathways. These results suggest that duloxetine could alleviate the OXA-induced peripheral neuropathy. Duloxetine deserves further consideration as a potential protective agent against peripheral neuropathy.

Abstract
INTRODUCTION Inguinal hernia is one of the most common surgical diseases in the world. Today, this disease is treated by surgical technique only. Among the late complications after surgery, the most frequent is the appearance of chronic post-operative pain after surgical treatment. The incidence of this complication is about 28% of patients undergoing hernioplasty suffering a varying degree of chronic pain, severe enough to interfere with normal daily activities. OBJECTIVES In this study we evaluated the onset of the neuropathic pain as a complication of inguinal prosthetic hernioplasty surgery. METHODS This is a prospective observational study run between September 2019 and August 2020. All patients, during the first visit conducted in an outpatient clinic, were recruited in a specific database. Subsequently, surgery was planned in election on one day surgery, patients were administered a specific questionnaire aiming at the identification of any pain and its exact location. The Inguinal Pain Questionnarie (IPQ) was used. During the surgical procedure the selective neurectomy of the 3 nerves has been documented, the entire population of patients has undergone a standardized surgical treatment. At the end of surgery, a follow-up was carried out administering two questionnaires (IPQ Short Form Modified and the IPQ Short Form Paresthesia Modified) concerning the possible chronic post-operative pain and the eventual paresthesia. The questionnaires were administered at first, third and sixth month from the date of surgery. RESULTS A total of 266 patients were screened from September 2019 to October 2020. Fiftyseven male patients were included in the study with a confirmed diagnosis of primary inguinal hernia. Clinical data, baseline characteristics and outcomes are described. Preoperatively, at the time of IPQ administration, 1.8% of patients had a pain score of 6, 10% of 5, 21% of 4, 31% of 3, 28% with a score of 2 and 7% of patients with a score of 1. In all cases the ileoinguinals and ileohypogastric nerves found were subjected to neurectomy, in 19% of cases also the genitofemoral nerve was subjected to surgical resection. At the end of the follow-up, the first questionnaire (IPQ Short Form Modified) results did show that, among the total of patients who had an open prosthetic hernioplasty with extensive nerves resection in the inguinal canal, 84% of them indicated a pain score equal to 0 (no pain) after 6 months of treatment and only 1.7% indicated a score equal to 4. Analyzing the second questionnaire on paresthesia (IPQ Short Form Paresthesia Modified), 79% of patients indicated a score equal to 0 by describing no paresthesia and no changes in sensitivity; 15.7% score 1; 3.5% score 2; 1.7% score 3. CONCLUSIONS Based on our experience and according to the modern literature, we would advise prophylactic total neurectomy of the inguinal canal nerves during prosthetic inguinal hernioplasty.

Abstract
Chemotherapy-induced peripheral neuropathy (CIPN) is the main dose-limiting adverse effect of chemotherapy drugs such as paclitaxel (PTX). PTX causes marked molecular and cellular damage, mainly in the peripheral nervous system, including sensory neurons in the dorsal root ganglia (DRG). Several studies have shown the therapeutic potential of cannabinoids, including cannabidiol (CBD), the major non-psychotomimetic compound found in the Cannabis plant, to treat peripheral neuropathies. Here, we investigated the efficacy of PECS-101 (former HUF-101), a CBD fluorinated analog, on PTX-induced neuropathic pain in mice. PECS-101, administered after the end of treatment with PTX, did not reverse mechanical allodynia. However, PECS-101 (1 mg/kg) administered along with PTX treatment caused a long-lasting relief of the mechanical and cold allodynia. These effects were blocked by a PPARγ, but not CB1 and CB2 receptor antagonists. Notably, the effects of PECS-101 on the relief of PTX-induced mechanical and cold allodynia were not found in macrophage-specific PPARγ-deficient mice. PECS-101 also decreased PTX-induced increase in Tnf, Il6, and Aif1 (Iba-1) gene expression in the DRGs and the loss of intra-epidermal nerve fibers. PECS-101 did not alter motor coordination, produce tolerance, or show abuse potential. In addition, PECS-101 did not interfere with the chemotherapeutic effects of PTX. Thus, PECS-101, a new fluorinated CBD analog, could represent a novel therapeutic alternative to prevent mechanical and cold allodynia induced by PTX potentially through the activation of PPARγ in macrophages.

Abstract
The sigma-1 receptor (Sig-1R) plays an important role in spinal pain transmission by increasing phosphorylation of the N-methyl-D-aspartate (NMDA) receptor GluN1 subunit (pGluN1). As a result Sig-1R has been suggested as a novel therapeutic target for prevention of chronic pain. Here we investigated whether interleukin-1β (IL-1β) modulates the expression of the Sig-1R in spinal astrocytes during the early phase of nerve injury, and whether this modulation affects spinal pGluN1 expression and the development of neuropathic pain following chronic constriction injury (CCI) of the sciatic nerve. Repeated intrathecal (i.t.) administration of IL-1β from days 0-3 post-surgery significantly reduced the increased pGluN1 expression at the Ser896 and Ser897 sites in the ipsilateral spinal cord, as well as, the development of mechanical allodynia and thermal hyperalgesia in the ipsilateral hind paw of CCI mice, which were restored by co-administration of IL-1 receptor antagonist with IL-1β. Sciatic nerve injury increased the expression of Sig-1R in astrocytes of the ipsilateral spinal cord, and this increase was suppressed by i.t. administration of IL-1β. Agonistic stimulation of the Sig-1R with PRE084 restored pGluN1 expression and the development of mechanical allodynia that were originally suppressed by IL-1β in CCI mice. Collectively these results demonstrate that IL-1β administration during the induction phase of neuropathic pain produces an analgesic effect on neuropathic pain development by controlling the expression of Sig-1R in spinal astrocytes.

Abstract
Pyramidal neurons in the anterior cingulate cortex (ACC), a prefrontal region involved in processing the affective components of pain, display hyperexcitability in chronic neuropathic pain conditions, and their silencing abolishes hyperalgesia. We show that dopamine, through D1 receptor (D1R) signaling, inhibits pyramidal neurons of mouse ACC by modulation of hyperpolarization-activated cyclic nucleotide-gated (HCN) channels. Activation of Gs-coupled D1R by dopamine induces the opening of HCN channels at physiological membrane potentials, driving a significant decrease in input resistance and excitability. Systemic L-DOPA in chronic neuropathic mice rescues HCN channel activity, normalizes pyramidal excitability in ACC, and blocks mechanical and thermal allodynia. Moreover, microinjection of a selective D1R agonist in the ACC relieves the aversiveness of ongoing neuropathic pain, while an ACC D1R antagonist blocks gabapentin- and lidocaine-evoked antinociception. We conclude that dopaminergic inhibition via D1R in ACC plays an analgesic role in physiological conditions and is decreased in chronic pain.

Abstract
BACKGROUND Neuropathic pain is a debilitating disease with few effective treatments. Emerging evidence indicates the involvement of mitochondrial dysfunction and oxidative stress in neuropathic pain. Nuclear factor erythroid 2-related factor 2 (Nrf2) is a potent regulator of the antioxidant response system. In this study, we investigated whether RTA-408 (RTA, a novel synthetic triterpenoid under clinical investigation) could activate Nrf2 and promote mitochondrial biogenesis (MB) to reverse neuropathic pain and the underlying mechanisms. METHODS Neuropathic pain was induced by chronic constriction injury (CCI) of the sciatic nerve. Pain behaviors were measured via the von Frey test and Hargreaves plantar test. The L4-6 spinal cord was collected to examine the activation of Nrf2 and MB. RESULTS RTA-408 treatment significantly reversed mechanical allodynia and thermal hyperalgesia in CCI mice in a dose-dependent manner. Furthermore, RTA-408 increased the activity of Nrf2 and significantly restored MB that was impaired in CCI mice in an Nrf2-dependent manner. Peroxisome proliferator-activated receptor-gamma coactivator-1alpha (PGC-1α) is the key regulator of MB. We found that the PGC-1α activator also induced a potent analgesic effect in CCI mice. Moreover, the antinociceptive effect of RTA-408 was reversed by the preinjection of the PGC-1α inhibitor. CONCLUSIONS Nrf2 activation attenuates chronic constriction injury-induced neuropathic pain via induction of PGC-1α-mediated mitochondrial biogenesis in the spinal cord. Our results indicate that Nrf2 may be a potential therapeutic strategy to ameliorate neuropathic pain and many other disorders with oxidative stress and mitochondrial dysfunction.

Abstract
Currently, limited information regarding the role of calcitonin gene-related peptide (CGRP) in neuropathic pain is available. Intracerebroventricular administrations of an anti-CGRP antibody were performed in rats with infraorbital nerve ligation. Anti-CGRP antibody administration attenuated mechanical and heat hypersensitivities induced by nerve ligation and decreased the phosphorylated extracellular signal-regulated kinase expression levels in the trigeminal spinal subnucleus caudalis (Vc) following mechanical or heat stimulation. An increased CGRP immunoreactivity in the Vc appeared after nerve ligation. A decreased CGRP immunoreactivity resulted from anti-CGRP antibody administration. Our findings suggest that anti-CGRP antibody administration attenuates the symptoms of trigeminal neuropathic pain by acting on CGRP in the Vc.

Abstract
Musculoskeletal and psychological complaints have increased with the widespread use of visual display terminals, and musculoskeletal pain is known to be closely related to stress. One method of experimentally inducing persistent muscle pain is repeated cold stress (RCS), and animals exposed to such stress exhibit a dysfunction in the descending pain inhibitory system. Acetaminophen (N-acetyl-p-aminophenol; APAP) is widely used to relieve several types of pain, including musculoskeletal pain, and is available as an OTC drug. However, the mechanism underlying its analgesic action has not yet been fully elucidated. In this study, we compared the analgesic effect of APAP on RCS-induced muscular hyperalgesia with those of other analgesics to identify its mechanism of action. The daily oral administration of APAP significantly suppressed the decrease in the mechanical withdrawal threshold caused by RCS, similar to the results for neurotropin but not for the cyclooxygenase inhibitor ibuprofen (IBP). Moreover, the intrathecal administration of antagonists of the 5-hydroxytryptamine (5-HT)3 receptor or α2-adrenoceptor significantly abolished the analgesic effect of APAP but not of IBP. These results suggest that the analgesic effect of APAP on RCS-induced muscular pain might be exerted due to the activation of the descending pathways involving the spinal 5-HT3 receptor or α2-adrenoceptor.

Abstract
Trigeminal neuropathic pain (TNP) led to vital cognitive functional deficits such as impaired decision-making abilities in a rat gambling task. Chronic TNP caused hypomyelination in the anterior cingulate cortex (ACC) associated with decreased synchronization between ACC spikes and basal lateral amygdala (BLA) theta oscillations. The aim of this study was to investigate the effect of pain suppression on cognitive impairment in the early or late phases of TNP. Blocking afferent signals with a tetrodotoxin (TTX)-ELVAX implanted immediately following nerve lesion suppressed the allodynia and rescued decision-making deficits. In contrast, the TTX used at a later phase could not suppress the allodynia nor rescue decision-making deficits. Intra-ACC administration of riluzole reduced the ACC neural sensitization but failed to restore ACC-BLA spike-field phase synchrony during the late stages of chronic neuropathic pain. Riluzole suppressed allodynia but failed to rescue the decision-making deficits during the late phase of TNP, suggesting that early pain relief is important for recovering from pain-related cognitive impairments. The functional disturbances in ACC neural circuitry may be relevant causes for the deficits in decision making in the chronic TNP state.

Abstract
Although millions of people are diagnosed with cancer each year, survival has never been greater thanks to early diagnosis and treatments. Powerful chemotherapeutic agents are highly toxic to cancer cells, but because they typically do not target cancer cells selectively, they are often toxic to other cells and produce a variety of side effects. In particular, many common chemotherapies damage the peripheral nervous system and produce neuropathy that includes a progressive degeneration of peripheral nerve fibers. Chemotherapy-induced peripheral neuropathy (CIPN) can affect all nerve fibers, but sensory neuropathies are the most common, initially affecting the distal extremities. Symptoms include impaired tactile sensitivity, tingling, numbness, paraesthesia, dysesthesia, and pain. Since neuropathic pain is difficult to manage, and because degenerated nerve fibers may not grow back and regain normal function, considerable research has focused on understanding how chemotherapy causes painful CIPN so it can be prevented. Due to the fact that both therapeutic and side effects of chemotherapy are primarily associated with the accumulation of reactive oxygen species (ROS) and oxidative stress, this review focuses on the activation of endogenous antioxidant pathways, especially PPARγ, in order to prevent the development of CIPN and associated pain. The use of synthetic and natural PPARγ agonists to prevent CIPN is discussed.

Abstract
The objective of study was to investigate the inhibitory effect of sinomenine on neuropathic pain on dorsal root ganglia (DRG). The DRG cell line and spinal nerve ligation (SNL) model were used in this study. The effect of sinomenine on the cell viability was examined by MTT assay. The expression of p38 MAPK, NF-κB, c-fos, SP and TNF-α was detected by using immunofluorescence and immunohistochemistry assay. We also assessed the level of p-CaMKII, COX-2, p-CREB, IL-17A, TLR4 and IL-1β via western blotting and RT-qPCR. Compared to the controls, sinomenine showed a protective effect on TNF-α-induced apoptosis on DRG cells in a dose-dependent manner, with an increase of cell viability and a decrease of reactive oxygen species level as well as LDH release. Parallelly, sinomenine treatment significantly reduced the expression of various factors related to stress and inflammation, including p38 MAPK, NF-κB, c-fos, p-CAMKII, COX-2, p-CREB, TLR4 and IL-17A in DRG cells in vitro. Furthermore, we found that administration of sinomenine significantly reduced mechanical withdrawal threshold and thermal withdrawal latency and inhibited the inflammation and activation of p38 signaling in SNL rats. It is noting that combined therapy of sinomenine and pulsed radiofrequency exhibited higher efficacy of dorsal root ganglia inflammation than single treatment as well as the combination of oxycodone and pulsed radiofrequency. Sinomenine inhibited the apoptosis of DRG cell by regulating p38 MAPK/CREB signalling pathway, which provides evidence to alleviate neuropathic pain in clinic.

Abstract
Objectives Worldwide, diabetic neuropathy (DN) is a major complication of diabetes mellitus. The direct renin inhibitor aliskiren is recognized as a treatment for cardiovascular disease in diabetic patients, but little is known about its potential benefits in cases of diabetic neuropathy. Accordingly, we investigated the effects of aliskiren (ALIS) and gliclazide (GLZ) and their combination therapy on peripheral neuropathy in streptozotocin-induced diabetic rats. Methods In total, 112 adult Sprague-Dawley rats were used for this study. Diabetes was induced using streptozotocin (STZ), whereas the control group was treated with an equal volume of citrate buffer. The diabetic rats were divided randomly into six groups according to the proposed treatment regime: diabetic control (DC), gliclazide (GLZ), aliskiren (ALIS), ramipril (RAM), (GLZ + ALIS) and (GLZ + RAM). Behavioural responses to thermal (hot-plate) and mechanical (tail-pinch) pain were evaluated. After eight weeks of daily treatments, the animals were fasted and sacrificed. The blood samples were collected, with the serum separated and subjected to various biochemical and enzyme analyses so as to assess the effect of the treatments on diabetic peripheral neuropathy. Results After 8 weeks, aliskiren alone and in combination with gliclazide therapy had a significant effect (P < .001) in reducing blood glucose levels and showed increased hot-plate and tail-flick latencies compared with the diabetic control group. The threshold of mechanical hyperalgesia was also significantly elevated (P < .001). Conclusions/Interpretations These data suggest that either aliskerin alone or in combination with gliclazide can protect against the development and progression of diabetic neuropathy.

Abstract
High glucose (HG)-induced nucleotide-binding and oligomerization (NACHT) domain, leucine-rich repeat (LRR), and pyrin domain (PYD)-containing protein 3 (NLRP3) inflammasome activation leads to diabetic neuropathic pain. We recently showed that salidroside could suppress NLRP3 inflammasome activation in hepatocytes exposed to HG. The aim of this study was to evaluate the analgesic effect of salidroside on diabetic rats and to explore its underlying mechanisms. Rat models with diabetic neuropathic pain were induced by high-fat diet feeding combined with low dose streptozotocin injections. Doses of salidroside at 50 and 100 mg.kg-1.day-1 were administered by gavage to diabetic rats for 6 weeks. Mechanical allodynia test, thermal hyperalgesia test and biochemical analysis were performed to evaluate therapeutic effects. Primary dorsal root ganglion (DRG) cells exposed to HG at 45 mM were used to further study the effects of salidroside on the AMP-activated protein kinase (AMPK)-NLRP3 inflammasome axis and insulin sensitivity in vitro. Salidroside administration improved hyperglycemia, ameliorated insulin resistance, and alleviated neuropathic pain in diabetic rats. Moreover, salidroside induced AMPK activation and suppressed NLRP3 inflammasome activation in the DRGs of diabetic rats. In addition, salidroside treatment relieved oxidative stress, improved insulin sensitivity and regulated the AMPK-NLRP3 inflammasome axis in HG-treated DRGs in vitro. Furthermore, AMPK inhibition in vivo or AMPK silencing in vitro abolished the beneficial effects of salidroside on diabetic neuropathic pain. Together, these results indicate that salidroside alleviates diabetic neuropathic pain through its regulation of the AMPK-NLRP3 inflammasome axis in DRGs.

Abstract
Effective treatments for chronic pain without abuse liability are urgently needed. One in 5 adults suffer chronic pain and half of these patients report inefficient treatment. Mu opioid receptor agonists (MOP), including oxycodone, tramadol and morphine, are often prescribed to treat chronic pain, however, use of drugs targeting MOP can lead to drug dependency, tolerance and overdose deaths. Kappa opioid receptor (KOP) agonists have antinociceptive effects without abuse potential; however, they have not been utilised clinically due to dysphoria and sedation. We hypothesise that mixed opioid receptor agonists targeting the KOP and delta opioid receptor (DOP) would have a wider therapeutic index, with the rewarding effects of DOP negating the negative effects of KOP. MP1104, an analogue of 3-Iodobenzoyl naltrexamine, is a novel mixed opioid receptor agonist with potent antinociceptive effects mediated via KOP and DOP in mice without rewarding or aversive effects. In this study, we show MP1104 has potent, long-acting antinociceptive effects in the warm-water tail-withdrawal assay in male and female mice and rats; and is longer acting than morphine. In the paclitaxel-induced neuropathic pain model in mice, MP1104 reduced both mechanical and cold allodynia and unlike morphine, did not produce tolerance when administered daily for 23 days. Moreover, MP1104 did not induce sedative effects in the open-field locomotor activity test, respiratory depression in mice using whole-body plethysmography, or have cross-tolerance with morphine. This data supports the therapeutic development of mixed opioid receptor agonists, particularly mixed KOP/DOP agonists, as non-addictive pain medications with reduced tolerance.

Abstract
At the neuro-vascular emergencies unit at the Pitié-Salpêtrière (AP-HP,Paris), a population that is mostly elderly and dependent is cared for daily by caregivers. With an average age of stroke of 74 years, these patients regularly suffer from neuropathic pain in post-stroke situations. Caregivers are very vigilant in preventing pain induced during care, particularly during mobilization, and are developing holistic pain management that includes non-drug approaches.

Abstract
Neuropathic pain is still a critical public health problem worldwide. Thereby, the search for novel and more effective strategies against neuropathic pain is urgently considered. It is known that neuroinflammation plays a crucial role in the pathogenesis of neuropathic pain. SedumLineare Thunb. (SLT), a kind of Chinese herb originated from the whole grass of Crassulaceae plant, was reported to possess anti-inflammatory activity. However, whether SLT has anti-nociceptive effect on neuropathic pain and its possible underlying mechanisms remains poorly elucidated. In this study, a rat model of neuropathic pain induced by spared nerve injury (SNI)was applied. SLT (p.o.) was administered to SNI rats once every day lasting for 14 days. Pain-related behaviors were assessed by using paw withdrawal threshold (PWT) and CatWalk gait parameters. Expression levels of inflammatory mediators and pain-related signaling molecules in the spinal cord were detected using western blotting assay. The results revealed that SLT (30, 100, and 300 mg/kg, p.o.) treatment for SNI rats ameliorated mechanical hypersensitivity in a dose-dependent manner. Application of SLT at the most effective dose of 100 mg/kg to SNI rats not only significantly blocked microglial activation, but also markedly reduced the protein levels of spinal HMGB1, TLR4, MyD88, TRAF6, IL-1β, IL-6, and TNF-α, along with an enhancement in gait parameters. Furthermore, SLT treatment dramatically inhibited the phosphorylation levels of both IKK and NF-κB p65 but obviously improved both IκB and IL-10 protein expression in the spinal cord of SNI rats. Altogether, these data suggested that SLT could suppress spinal TLR4/NF-κB signaling pathway in SNI rats, which might at least partly contribute to its anti-nociceptive action, indicating that SLT may serveas a potential therapeutic agent for neuropathic pain.

Abstract
Resiniferatoxin is an ultrapotent capsaicin analog that mediates nociceptive processing; treatment with resiniferatoxin can cause an inflammatory response and, ultimately, neuropathic pain. Hepatoma-derived growth factor, a growth factor related to normal development, is associated with neurotransmitters surrounding neurons and glial cells. Therefore, the study aims to investigate how blocking hepatoma-derived growth factor affects the inflammatory response in neuropathic pain. Serum hepatoma-derived growth factor protein expression was measured via ELISA. Resiniferatoxin was administrated intraperitoneally to induce neuropathic pain in 36 male Sprague-Dawley rats which were divided into three groups (resiniferatoxin+recombinant hepatoma-derived growth factor antibody group, resiniferatoxin group, and control group) (n = 12/group). The mechanical threshold response was tested with calibration forceps. Cell apoptosis was measured by TUNEL assay. Immunofluorescence staining was performed to detect apoptosis of neuron cells and proliferation of astrocytes in the spinal cord dorsal horn. RT-PCR technique and western blot were used to measure detect inflammatory factors and protein expressions. Serum hepatoma-derived growth factor protein expression was higher in the patients with sciatica compared to controls. In resiniferatoxin-group rats, protein expression of hepatoma-derived growth factor was higher than controls. Blocking hepatoma-derived growth factor improved the mechanical threshold response in rats. In dorsal root ganglion, blocking hepatoma-derived growth factor inhibited inflammatory cytokines. In the spinal cord dorsal horn, blocking hepatoma-derived growth factor inhibited proliferation of astrocyte, apoptosis of neuron cells, and attenuated expressions of pain-associated proteins. The experiment showed that blocking hepatoma-derived growth factor can prevent neuropathic pain and may be a useful alternative to conventional analgesics.

Abstract
Peripheral nerve injury often leads to neuropathic pain. In the present study, we assessed the role of liver x receptor alpha (LXRα), an oxysterol regulated nuclear transcription factor that promotes reverse cholesterol transport and alternative (M2) macrophage activation, in the development of neuropathic pain. We found that compared to WT mice, in LXRα knockout mice the development of mechanical allodynia following sciatic nerve crush was accelerated and the duration was prolonged. Furthermore, the expression of M1-like macrophage marker iNOS and M1-like macrophages inducer hydrogen peroxide (H2O2) was increased, whereas expression of M2 macrophage marker arginase-1 (Arg-1) and interleukin-10 (IL-10) was reduced in the sciatic nerve of LXRα knockout mice. Moreover, peri-sciatic administration of LXRs agonist GW3965, immediately after the nerve crush, into wild type mice, suppressed the mechanical allodynia induced by crush injury. GW3965 also suppressed the expression of iNOS and production of H2O2 in the injured nerve and enhanced the expression of IL-10 and Arg-1. Importantly, peri-sciatic administration of IL-10 neutralization antibody prevented the alleviating effect of GW3965 on mechanical allodynia. Altogether, these results indicates that the lack of LXRα in the sciatic nerve results in an augmented inflammatory profile of macrophages, which ultimately speed up the development of neuropathic pain and dampen its recovery following nerve injury. Activation of LXRα by its agonist might rebalance the neuroprotective and neurotoxic macrophage phenotypes, and thus alleviate the neuropathic pain behavior.

Abstract
AIM To explore the inhibitory effect of FSC231, a PDZ domain inhibitor of protein interacting with C kinase 1 (PICK1), on paclitaxel induced neuralgia and its possible pathways. METHODS Forty C57BL/6 mice were randomly divided into four groups (n = 10): the control group (CON), the FSC231 group (FSC), the paclitaxel group (PTL) and the FSC231 add paclitaxel group (F + P). Behavioral indictors of mice including the mechanical pain threshold, foot contraction reflex and inhibition rate were evaluated. ELISA, RT-qPCR and Western Blot were performed to determine the expression levels of IL-1β, IL-10, substance P and PICK1. RESULTS Compared with the control group, the foot contraction reflex time, mechanical pain threshold and IL-10 levels were significantly reduced in the PTL group, and IL-1β, substance P and PICK1 levels were significantly increased (P < 0.05). Compared with the PTL group, the foot contraction reflex time, mechanical pain threshold and IL-10 level were significantly increased, while IL-1β, SP and PICK1 levels were significantly decreased in the F + P group (P < 0.05). CONCLUSION FSC231 could alleviate paclitaxel-induced neuralgia by inhibiting PICK1 and affecting the secretion of inflammatory factors and substance P. The results of this study provide experimental basis for FSC231 to treat neuralgia caused by chemotherapy.

Abstract
BACKGROUND Herpes zoster, is one of the most familiar skin diseases in conducted a systematic review and meta-analysis in 2018 showed that fire needle acupuncture can relieve the pain caused by herpes zoster quickly and prevent the outcome of postherpetic neuralgia (PHN), with little side effects. The purpose of this study is to update the systematic review with the latest evidence. METHODS Four English (PubMed, Embase, the Cochrane Library, the Web of Science) and 4 Chinese databases (CNKI, Wanfang, VIP, and CBM) will be searched dating until 30 June 2020 for randomized controlled trials with no language restrictions. In addition, a hand search of the reference lists of included studies will also be done. Adults (aged 18-70) with acute herpes zoster (less than 7 days) using fire needle acupuncture will be included. Pairs of researchers will independently conduct the search, screen titles and abstracts, retrieve full texts of potentially eligible studies, assess the risk of bias, and conduct date extraction and synthesis. If there is any discrepancy in the whole process, consult a third researcher. For meta-analysis, the primary outcome is the pain intensity (visual analogue scale [VAS] pain scale; pain relieve of 30%, duration of pain), and the second outcome is incidence of PHN. A sequential analysis will be done to test the robustness of results of meta-analysis. The quality of evidence will be assessed using GRADE system. RESULTS The results will be published in a peer-reviewed journal. CONCLUSION This study will provide the latest systematic review and meta-analysis of fire needle acupuncture for acute herpes zoster and prevention of PHN.

Abstract
Cancer is a common disease threatening human health, chemotherapy is widely used in clinical treatment of cancer, but chemotherapy-induced peripheral neuropathy (CIPN) has a relevant impact on life quality of cancer patients. Administration of gastrodin can relieve chronic pain to cancer patients with CIPN and attenuated the inflammatory response by reducing the expression of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6). However, its exact molecular mechanisms remain unclear. In this study, we established an animal model of CIPN using Walker-256 breast cancer cell and vincristine. We found that the mechanical and thermal pain threshold of rats was decreased with treatment of vincristine. Using gastrodin could restore the mechanical and thermal threshold without interfering anti-tumor effect of vincristine. Gastrodin relieved CIPN by inhibiting activation of spinal microglia through Fractalkine (CX3CL1) and its receptor CX3CR1, then inhibited P38/mitogen-activated protein kinase (MAPK) signaling pathway and reduced the expression of inflammatory factor TNF-α and interleukin-1β (IL-1β). Taking together, our study demonstrated that gastrodin is a potential drug for the treatment of CIPN and likely to improve cancer patient's life quality.

Abstract
Although chemotherapy is a key cancer treatment, many chemotherapeutic drugs produce chronic neuropathic pain, called chemotherapy-induced neuropathic pain (CINP), which is a dose-limiting adverse effect. To date, there is no medicine that prevents CINP in cancer patients and survivors. We determined whether blockers of the canonical Wnt signaling pathway prevent CINP. Neuropathic pain was induced by intraperitoneal injection of paclitaxel (PAC) on four alternate days in male Sprague-Dawley rats or male Axin2-LacZ knock-in mice. XAV-939, LGK-974, and iCRT14, Wnt/β-catenin blockers, were administered intraperitoneally as a single or multiple doses before or after injury. Mechanical allodynia, phosphoproteome profiling, Wnt ligands, and inflammatory mediators were measured by von Frey filament, phosphoproteomics, reverse transcription-polymerase chain reaction, and Western blot analysis. Localization of β-catenin was determined by immunohistochemical analysis in the dorsal root ganglia (DRGs) in rats and human. Our phosphoproteome profiling of CINP rats revealed significant phosphorylation changes in Wnt signaling components. Importantly, repeated systemic injections of XAV-939 or LGK-974 prevented the development of CINP in rats. In addition, XAV-939, LGK-974, and iCRT14 ameliorated CINP. PAC increased Wnt3a and Wnt10a, activated β-catenin in DRG, and increased monocyte chemoattractant protein-1 and interleukin-1β in DRG. PAC also upregulated rAxin2 in mice. Furthermore, β-catenin was expressed in neurons, including calcitonin gene-related protein-expressing neurons and satellite cells in rat and human DRG. In conclusion, chemotherapy increases Wnt3a, Wnt10a, and β-catenin in DRG and their pharmacological blockers prevent and ameliorate CINP, suggesting a target for the prevention and treatment of CINP.

Abstract
BACKGROUND MicroRNAs play a crucial role in diabetic peripheral neuropathic pain (DPNP). miR-590-3p is a novel miRNA and involved in multiple diseases. However, the pathological mechanism of miR-590-3p in DPNP needs to be elucidated. MATERIALS AND METHODS The db/db mice and db/m mice were selected to mimic diabetes and control, respectively, for in vivo studies. The miR-590-3p agomir was injected into db/db mice and pain-related behavioral tests were performed. The interaction of miR-590-3p with target gene was confirmed by dual-luciferase reporter assay. The expression of target gene was determined by qRT-PCR and western blot assay. The levels of inflammatory cytokines were measured by enzyme-linked immunosorbent assay (ELISA). RESULTS miR-590-3p was down-regulated in diabetic peripheral neuropathy mice. More importantly, miR-590-3p agomir alleviated pain-related behavior, reduced TNF-α, IL-1β and IL-6 concentrations, and inhibited neural infiltration by immune cells in db/db mice. Interestingly, RAP1A was predicted to be the target of miR-590-3p by Targetscan, and was actually regulated by miR-590-3p. Finally, the rescue experiments proved that overexpression of RAP1A partially abrogated the suppressive impact of miR-590-3p on T cells proliferation and migration. CONCLUSION miR-590-3p ameliorates DPNP via targeting RAP1A and inhibiting T cells infiltration, indicating that exogenous miR-590-3p may be a potential candidate for clinical treatment of DPNP.

Abstract
Diabetic peripheral neuropathic pain (DPNP) is a distal spontaneous pain, caused by lesion of sensory neurons and accompanied by depression and anxiety frequently, which reduce life quality of patients and increase society expenditure. To date, antidepressants, serotonin-noradrenaline reuptake inhibitors and anticonvulsants are addressed as first-line therapy to DPNP, alone or jointly. It is urgently necessary to develop novel agents to treat DPNP and its complications. Evidences indicate that neuropeptide galanin can regulate multiple physiologic and pathophysiological processes. Pain, depression and anxiety may upregulate galanin expression. In return, galanin can modulate depression, anxiety, pain threshold and pain behaviors. This article provides a new insight into regulative effects of galanin and its subtype receptors on antidepressant, antianxiety and against DPNP. Through activating GALR1, galanin reinforces depression-like and anxiogenic-like behaviors, but exerts antinociceptive roles. While via activating GALR2, galanin is referred to as anti-depressive and anti-anxiotropic compounds, and at low and high concentration facilitates and inhibits nociceptor activity, respectively. The mechanism of the galanin roles is relative to increase in K+ currents and decrease in Ca2+ currents, as well as neurotrophic and neuroprotective roles. These data are helpful to develop novel drugs to treat DPNP and its complications.

Abstract
BACKGROUND Painful diabetic neuropathy (PDN) is a common complication secondary to diabetes mellitus. Nav1.8 is an isoform of voltage-gated sodium channels and its expression regulation is closely related with PDN. MicroRNA-145 (miR-145) is involved in the occurrence and development of neuropathic pain. TargetScan software has revealed that Nav1.8 (SCN10A) is the major target of miR-145. However, its function between miR-145 and Nav1.8 in PDN is unknown. OBJECTIVES We aim to explore the regulatory effect of miR-145 on the expression and function of Nav1.8, which plays a pivotal role in precluding the advancement of neuropathic mechanical hyperalgesia in diabetic pain. STUDY DESIGN An experimental, animal study. SETTING An animal research facility at Nanjing Maternal and Child Health Institute, China. METHODS The paw mechanical withdrawal threshold (PMWT) of rats was assessed with the von Frey test. The adverse regulation of Nav1.8 by miR-145 was confirmed by a dual luciferase detection system in HEK293T cells. The mRNA level and expression of Nav1.8 in dorsal root ganglion (DRG) neurons were assessed with real-time polymerase chain reaction (real-time PCR), western blotting and immunofluorescence assays following intrathecal injection of agomiR-145 in vitro and in vivo. Whole-cell patch-clamping was applied to assess alterations in the tetrodotoxin-resistant (TTX-R) sodium current (Nav1.8) in DRGs. RESULTS The PMWT was significantly decreased in rats following streptozotocin (STZ) injection on Day 7 and was maintained at a lower level on Day 28; this change was accompanied by changes in the expression of Nav1.8 in DRG neurons, which was increased 3 days after STZ injection and reached a maximal level on Day 14. The early knockdown of Nav1.8 with siRNA or agomiR-145 treatment on Day 8 effectively precluded the deterioration of pain behaviors in STZ-treated rats. The luciferase intensity was significantly decreased in HEK293T cells expressing wild-type SCN10A infected with miR-145 mimic. In addition, Nav1.8 overexpression was significantly repressed via overexpression of miR-145 in cultured DRG neurons, and neuronal hyperexcitability was concomitantly decreased. Furthermore, the intrathecal administration of agomiR-145 elicited a significant decrease in Nav1.8 expression in DRG neurons from STZ-treated rats on Day 14. LIMITATIONS The causes of PDN are likely to be multifactorial and inflammatory markers, such as IL-6, IL-2, and TNF-?, are elevated in hyperglycemia and might be the precipitating factors that contribute to miR-145 dysregulation. The curative effect of miR-145 upregulation in reversal of pain behaviors at the stage of well-established PDN wasn't investigated in this study. CONCLUSION Early infection with a lentiviral vector overexpressing miR-145 adversely regulated the expression and function of TTX-resistant Nav1.8 and abrogated the development of PDN. Therefore, miR-145 might be a potential therapeutic target for preventing PDN in the near future.

Abstract
Chemotherapy-induced neuropathic pain harms the quality of life patients. Vincristine is an often used chemotherapeutic drug that evokes neuralgia via inflammation. Puerarin (Pue) extracted from Puerariae Lobatae Radix has analgesic and anti-inflammatory effects; however, its possible effect and mechanism in vincristine (Vin)-induced neuropathic pain has not been investigated. The present research aimed to explore whether Pue could relieve chemotherapy-evoked neuropathic pain and the underlying mechanism actions. Rat neuropathic pain was established by intraperitoneal injection of vincristine. Pue was orally administered in two dose levels (25 or 50 mg/kg/d) for three weeks. The paw withdrawal latency and paw withdrawal threshold were performed to evaluate the pain behaviors. Inflammatory cytokines in the spinal cord and dorsal root ganglion were measured by ELISA kits. qRT-PCR, western blot, and immunofluorescence staining were employed to measure the level and expression feature of inflammatory cytokines. Our findings showed that Pue improved hyperalgesia and allodynia. Treatment with Pue restored the levels of tumor necrosis factor-α (TNF-α), and IL-1β and increased the levels of transforming growth factor-β (TGF-β), and interleukin-10 (IL-10). On the molecular level, treatment with Pue down-regulated the protein levels of IL-1β, and NF-κBp65 and up-regulated the protein levels of TGF-β, p-Smad2, and p-Smad3 (TGF-β/Smad) in the spinal cord and DRG. Immunofluorescence staining further demonstrated that Pue decreased the NF-κBp65 protein. Our findings imply that Pue relieved chemotherapy-induced neuropathic pain might be attributable to the suppression of inflammation cytokines. The anti-inflammation action of Pue might be associated with the activation of the TGF-β/Smad pathway, a novel mechanism exploring its prophylactic effect in vincristine-induced neuropathic pain.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Neuropathic pain, the incidence of which ranges from 5 to 8% in the general population, remains challenge in the treatment. Shaoyao Gancao decoction (SGD) is a Chinese classical formula used to relieve pain for thousands of years and has been applied for neuropathic pain nowadays. However, the effective components of SGD for the treatment of neuropathic pain remains unclear. AIMS OF STUDY To investigate the effect and potential mechanism of SGD against neuropathic pain and further reveal the effective components of SGD in the treatment of neuropathic pain. MATERIALS AND METHODS Spared nerve injury (SNI) model rats of neuropathic pain were orally given SGD to intervene, the components in vivo after SGD administration were determined, behavior indicators, biochemical parameters, and metabolomics were applied for assessing the efficacy. Then correlation between components and biomarkers was analyzed by pearson correlation method. To further measure the contribution of components to efficacy, the combination of partial least-squares regression (PLSR) and multi-index comprehensive method was carried out, according to the corresponding contribution degree of the results, the components with large contribution degree were considered as the effective components. RESULTS SGD exhibited a significant regulatory effect on neuropathic pain, which could increase the pain threshold and decrease the levels of SP, β-EP, PGE2 and NO. With the high resolution of UPLC-Q-TOF/MS technology, a total of 128 compounds from SGD were identified and 44 of them were absorbed in blood. Besides, 40 serum biomarkers were identified after intervention of SGD and the metabolic pathways were constructed. The key metabolic pathways including Glycerophospholipid metabolism, Linoleic acid metabolism, Alpha-linolenic acid metabolism, Glycosylphosphatidylinositol-anchor biosynthesis and Arachidonic acid metabolism may be related to the regulation of neuropathic pain. Metabolomics combined with PLSR and multi-index comprehensive method was utilized to discover 5 components including paeonol, DL-Arabinose, benzoic acid, hispaglabridin A and paeonilactone C as effective components of SGD in the treatment of neuropathic pain. This strategy was used to explore the effective components of SGD and elucidate its possible analgesic mechanism. CONCLUSION This study demonstrate that SGD significantly relieved neuropathic pain and elucidated the effective components of SGD for treating neuropathic pain, the strategy as an illustrative case study can be applied to other classical formula and is beneficial to improve the quality and efficacy.

Abstract
Injured somatosensory nervous system cause neuropathic pain which is quite difficult to treat using current approaches. It is therefore important to find new therapeutic options. We have analyzed cedrol effect on chronic constriction injury (CCI) induced neuropathic pain in rats. The mechanical and thermal hypersensitivity were evaluated using the von Frey filament, radiant heat and acetone drop methods. The changes in the levels of biomarkers of oxidative stress including malondialdehyde (MDA) and total thiol (SH), as well as inflammatory mediators including Tumour Necrosis Factor alpha (TNF-α) and Interleukin 6 (IL-6) were estimated in the lumbar portion (L4-L6) of neuropathic rats. Administration of cedrol attenuated the CCI-induced mechanical and thermal hypersensitivity. CCI produced an increase in MDA along with a reduction in SH levels in the spinal cord of the CCI rats. Reduced levels of SH were restored by cedrol. Also, the levels of MDA were reduced in the cedrol-treated CCI rats compared to the untreated CCI rats. Besides, level of TNF-α and IL-6 increased in the spinal cord of CCI group and cedrol could reverse it. The current study showed that cedrol attenuates neuropathic pain in CCI rats by inhibition of inflammatory response and attenuation of oxidative stress.

Abstract
Background Neuropathic pain, due to peripheral nerve damage, has influenced millions of people living all over the world. It has been shown that paroxetine can relieve neuropathic pain. Recently, the role of certain proteins like brain-derived neurotrophic factor (BDNF), GABAA receptor, and K+-Cl- cotransporter 2 (KCC2) transporter in the occurrence of neuropathic pain has been documented. In the current study, the expression of these proteins affected by paroxetine was evaluated. Methods Male Wistar rats were allocated into two main groups of pre- and post-injury. Rats in each main group received paroxetine before nerve injury and at day seven after nerve damage till day 14, respectively. The lumbar spinal cord of animals was extracted to assess the expression of target genes and proteins. Results In the preventive study, paroxetine decreased BDNF and increased KCC2 and GABAA gene and protein expression, while in the post-injury paradigm, it decreased BDNF and increased KCC2 genes and protein expression. In this regard, an increase in the protein expression of GABAA was observed. Conclusion It seems that paroxetine with a change in the expression of three significant proteins involved in neuropathic pain could attenuate this type of chronic pain.

Abstract
Paclitaxel-induced neuropathic pain (PINP) is refractory to currently used analgesics. Previous studies show a pivotal role of oxidative stress in PINP. Because the nuclear factor erythroid-2-related factor 2 (Nrf2) has been considered as the critical regulator of endogenous antioxidant defense, we here explored whether activation of Nrf2 could attenuate PINP. A rat model of PINP was established by intraperitoneal injection of paclitaxel (2 mg/kg) every other day with a final cumulative dose of 8 mg/kg. Hind paw withdrawal thresholds (PWTs) in response to von Frey filament stimuli were used to assess mechanical allodynia. We showed that a single dose of Nrf2 activator, oltipraz (10, 50, and 100 mg/kg), dose-dependently attenuated established mechanical allodynia, whereas repeated injection of oltipraz (100 mg· kg-1· d-1, i.p. from d 14 to d 18) almost abolished the mechanical allodynia in PINP rats. The antinociceptive effect of oltipraz was blocked by pre-injection of Nrf2 inhibitor trigonelline (20 mg/kg, i.p.). Early treatment with oltipraz (100 mg· kg-1· d-1, i.p. from d 0 to d 6) failed to prevent the development of the PINP, but delayed its onset. Western blot and immunofluorescence analysis revealed that the expression levels of Nrf2 and HO-1 were significantly upregulated in the spinal cord of PINP rats. Repeated injection of oltipraz caused further elevation of the expression levels of Nrf2 and HO-1 in the spinal cord of PINP rats, which was reversed by pre-injection of trigonelline. These results demonstrate that oltipraz ameliorates PINP via activating Nrf2/HO-1-signaling pathway in the spinal cord.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE In Iranian traditional medicine, Cuminum cyminum is a unique medicinal herb for pain relief. Cuminaldehyde has been distinguished as the major constituent of C. cyminum seeds; even though, the analgesic effect of cuminaldehyde has not yet been examined. AIM OF THE STUDY The nobility of this study was to assess cuminaldehyde effect on nociceptive and neuropathic pains; furthermore, evaluation of its possible mechanisms of action. MATERIALS AND METHODS Hot plate, formalin, and acetic acid-induced writhing tests were used to evaluate nociception in mice. Naloxone (opioid receptors antagonist), L-arginine (nitric oxide (NO) precursor), L-NAME (NO synthase inhibitor), sodium nitroprusside (NO donor), methylene blue (guanylyl cyclase inhibitor), sildenafil (phosphodiesterase inhibitor), and glibenclamide (KATP channel blocker) were used to determine the implication of opioid receptors and L-arginine/NO/cGMP/KATP channel pathway. Allodynia and hyperalgesia were investigated in the CCI (chronic constriction injury) model of neuropathic pain in rats. The ELISA method was used to measure the inflammatory cytokines in serum samples of rats. The entire chemicals were intraperitoneally injected. RESULTS Cuminaldehyde (100 and 200 mg/kg) significantly decreased the latency to nociceptive response in the hot plate test. The outcome of cuminaldehyde was completely antagonized by naloxone (2 mg/kg). Formalin- and acetic acid-induced nociception was significantly inhibited by cuminaldehyde (12.5-50 mg/kg). The antinociceptive effect of cuminaldehyde was reversed in writhing test by L-arginine (200 mg/kg), sodium nitroprusside (0.25 mg/kg), and sildenafil (0.5 mg/kg); however, L-NAME (30 mg/kg) and methylene blue (20 mg/kg) enhanced the effect of cuminaldehyde. Glibenclamide (10 mg/kg) did not alter the antinociceptive effects of cuminaldehyde. In the CCI-induced neuropathy, cuminaldehyde (25-100 mg/kg) significantly alleviated allodynia and hyperalgesia and decreased the serum levels of TNF-α and IL-1β. CONCLUSION It was attained magnificently that cuminaldehyde exerts antinociceptive and antineuropathic effects through the involvement of opioid receptors, L-arginine/NO/cGMP pathway, and anti-inflammatory function.

Abstract
Chronic pain affects a significant percentage of the United States population, and available pain medications like opioids have drawbacks that make long-term use untenable. Cannabinoids show promise in the management of pain, but long-term treatment of pain with cannabinoids has been challenging to implement in preclinical models. We developed a voluntary, gelatin oral self-administration paradigm that allowed male and female mice to consume ∆9-tetrahydrocannabinol, cannabidiol, or morphine ad libitum. Mice stably consumed these gelatins over 3 weeks, with detectable serum levels. Using a real-time gelatin measurement system, we observed that mice consumed gelatin throughout the light and dark cycles, with animals consuming less THC-gelatin than the other gelatin groups. Consumption of all three gelatins reduced measures of allodynia in a chronic, neuropathic sciatic nerve injury model, but tolerance to morphine developed after 1 week while THC or CBD reduced allodynia over three weeks. Hyperalgesia gradually developed after sciatic nerve injury, and by the last day of testing, THC significantly reduced hyperalgesia, with a trend effect of CBD, and no effect of morphine. Mouse vocalizations were recorded throughout the experiment, and mice showed a large increase in ultrasonic, broadband clicks after sciatic nerve injury, which was reversed by THC, CBD, and morphine. This study demonstrates that mice voluntarily consume both cannabinoids and opioids via gelatin, and that cannabinoids provide long-term relief of chronic pain states. In addition, ultrasonic clicks may objectively represent mouse pain status and could be integrated into future pain models.

Abstract
Neuropathic pain severely impairs rehabilitation and quality of life after spinal cord injury (SCI). The sphingosine-1-phosphate receptor agonist, FTY720, plays an important protective role in neuronal injury. This study aims to examine the effects of FTY720 in a rat acute SCI model, focusing on neuropathic pain. Female rats with SCI induced by 1-min clip compression were administered vehicle or 1.5 mg/kg of FTY720 24 h after the injury. Using the mechanical nociceptive threshold test, we monitored neuropathic pain and performed histological analysis of the pain pathway, including the μ opioid receptor (MOR), hydroxytryptamine transporter (HTT), and calcitonin gene-related peptide (CGRP). Motor score, SCI lesion volume, residual motor axons, inflammatory response, glial scar, and microvascular endothelial dysfunction were also compared between the two groups. FTY720 treatment resulted in significant attenuation of post-traumatic neuropathic pain. It also decreased systemic and local inflammation, thereby reducing the damaged areas and astrogliosis and resulting in motor functional recovery. Whereas there was no difference in the CGRP expression between the two groups, FTY720 significantly preserved the MOR in both the caudal and rostral areas of the spinal dorsal horn. Whereas HTT was preserved in the FTY720 group, it was significantly increased in the rostral side and decreased in the caudal side of the injury in the vehicle group. These results suggest that FTY720 ameliorates post-traumatic allodynia through regulation of neuroinflammation, maintenance of the blood-brain barrier, and inhibition of glial scar formation, thereby preserving the connectivity of the descending inhibitory pathway and reducing neuropathic pain.

Abstract
PURPOSE This assessor-blinded, prospective, randomized controlled clinical trial aimed at investigating the effect of classical massage on chemotherapy induced peripheral neuropathy and the quality of life (QOL) in breast cancer patients receiving adjuvant paclitaxel. METHODS A total of 40 female breast cancer patients were randomly allocated to the classical massage group (CMG) or the control group (CG). Classical massage was applied to the patients in the CMG before each paclitaxel infusion. The CG received only usual care. Presence of peripheral neuropathic pain and QOL were assessed at baseline and weeks 4, 8, 12, and 16. Nerve conduction studies (NCS) findings were also recorded at baseline and week 12. RESULTS The peripheral neuropathic pain was lower in the CMG compared to the CG at week 12 (p < 0.05). The sensory and motor sub-scale scores of the QOL measure showed statistically significant differences over time in favor of the CMG (p < 0.05). Sensory action potential amplitude of the median nerve was significantly higher and the tibial nerve latency was significantly shorter in the CMG compared to the CG at week 12. CONCLUSIONS This study suggested that classical massage successfully prevented chemotherapy-induced peripheral neuropathic pain, improved the QOL, and showed beneficial effects on the NCS findings.

Abstract
A chemotherapy drug, oxaliplatin, induces cold and mechanical hypersensitivity, but effective treatments for this neuropathic pain without side effects are still lacking. We previously showed that Cinnamomi Cortex suppresses oxaliplatin-induced pain behaviors in rats. However, it remains unknown which phytochemical of Cinnamomi Cortex plays a key role in that analgesic action. Thus, here we investigated whether and how cinnamic acid or cinnamaldehyde, major components of Cinnamomi Cortex, alleviates cold and mechanical allodynia induced by a single oxaliplatin injection (6 mg/kg, i.p.) in rats. Using an acetone test and the von Frey test for measuring cold and mechanical allodynia, respectively, we found that administration of cinnamic acid, but not cinnamaldehyde, at doses of 10, 20 and 40 mg/kg (i.p.) significantly attenuates the allodynic behaviors in oxaliplatin-injected rats with the strongest effect being observed at 20 mg/kg. Our in vivo extracellular recordings also showed that cinnamic acid (20 mg/kg, i.p.) inhibits the increased activities of spinal wide dynamic range neurons in response to cutaneous mechanical and cold stimuli following the oxaliplatin injection. These results indicate that cinnamic acid has an effective analgesic action against oxaliplatin-induced neuropathic pain through inhibiting spinal pain transmission, suggesting its crucial role in mediating the effect of Cinnamomi Cortex.

Abstract
Investigation of pain requires measurements of nociceptive sensitivity and other pain-related behaviors. Recent studies have indicated the superiority of gait analysis over traditional evaluations (e.g., skin sensitivity and sciatic function index [SFI]) in detecting subtle improvements and deteriorations in animal models. Here, pain-related gait parameters, whose criteria include (1) alteration in pain models, (2) correlation with nociceptive threshold, and (3) normalization by analgesics, were identified in representative models of neuropathic pain (spared nerve injury: coordination data) and inflammatory pain (intraplantar complete Freund’s adjuvant: both coordination and intensity data) in the DigiGait™ and CatWalk™ systems. DigiGait™ had advantages in fixed speed (controlled by treadmill) and dynamic SFI, while CatWalk™ excelled in intrinsic velocity, intensity data, and high-quality 3D images. Insights into the applicability of each system may provide guidance for selecting the appropriate gait imaging system for different animal models and optimization for future pain research.

Abstract
CONTEXT Chronic postmastectomy pain syndrome (PMPS) has a considerable negative impact on the quality of life of breast cancer patients. OBJECTIVE The objective of this study was to assess the possible preventive role of perioperative pregabalin in PMPS. METHODS This randomized controlled study included 200 patients with breast cancer scheduled for elective breast cancer surgery. They were randomly assigned to one of two treatment groups. The pregabalin group received 75 mg of pregabalin twice daily for seven days and the control group received oral equivalent placebo capsules. The primary outcome was development of neuropathic PMPS. Neuropathic pain was assessed using the Grading System for Neuropathic Pain. Secondary outcome measures were safety and Visual Analogue Scale scores. RESULTS Neuropathic pain was significantly less frequent in the pregabalin group compared to the control group at four weeks (P = 0.005), 12 weeks (P = 0.002), and 24 weeks (P < 0.001) postoperatively. PMPS was diagnosed in 11 patients (11%) of the pregabalin group and 29 patients (29%) of the control group (P < 0.001, relative risk: 0.26, 95% CI: 0.12-0.56). At the three follow-up time points, Visual Analogue Scale scores during the first three postoperative weeks were comparable in both groups while they were significantly lower in the pregabalin group at 4, 12, and 24 weeks. These two groups were comparable in the frequency of adverse events (P = 0.552). CONCLUSION Perioperative oral pregabalin 75 mg twice daily, starting at the morning of surgery and continued for one week, could reduce the frequency of postmastectomy pain syndrome.

Abstract
BACKGROUND Inguinal hernia repair is one of the most common surgical procedures in man. Immediate postoperative pain is an important issue that can delay hospital discharge. Besides, the presence of chronic pain after herniorrhaphy, which can affect up to 50% of patients, is a growing concern. However information regarding the precise etiological factors of this chronic postoperative pain is lacking. One factor thought to contribute to post herniorrhaphy chronic pain is the surgical procedure for inguinal hernia repair used by the surgeon. MATERIALS AND METHOD The study was conducted over a period of 5 years and included 1000 consecutive patients operated with inguinal hernia. Each patients completed a questionnaire about the presence or absence of pain or sensory disorders. After completed only 365 of patients remains in the study. From this patients, a total of 38 had different intensity of pain. From those, 13% were operated through an tissular procedure, whereas the laparoscopic procedure was responsible only for 7% of the patients with chronic postoperative pain. Most of the patients had mild or moderate pain and only one patient experienced severe pain. According to the type of procedure performed, in 25 patients were used the tissular procedure and only 12 patients with laparoscopic hernia repair had chronic pain. CONCLUSION The etiology of chronic groin pain post hernia repair is related in part to nerve injury. This is supported by the high frequency of sensory symptoms and numbness in these patients. However other factors including the role of tissue injury and inflammatory postoperative changes need to be considered. KEY WORDS Chronic postoperative pain, Inguinal hernia repair, Open surgery, Laparoscopic surgery.

Abstract
There is a growing interest on the role of autophagy in diabetes pathophysiology, where development of neuropathy is one of the most frequent comorbidities. We have previously demonstrated that neuropathic pain after nerve damage is exacerbated in autophagy-defective heterozygous Ambra1 mice. Here, we show the existence of a prediabetic state in Ambra1 mice, characterized by hyperglycemia, intolerance to glucose and insulin resistance. Thus, we further investigate the hypothesis that prediabetes may account for the exacerbation of allodynia and chronic pain and that counteracting the autophagy deficit may relieve the neuropathic condition. We took advantage from caloric restriction (CR) able to exert a double action: a powerful increase of autophagy and a control on the metabolic status. We found that CR ameliorates neuropathy throughout anti-inflammatory and metabolic mechanisms both in Ambra1 and in WT animals subjected to nerve injury. Moreover, we discovered that nerve lesion represents, per se, a metabolic stressor and CR reinstates glucose homeostasis, insulin resistance, incomplete fatty acid oxidation and energy metabolism. As autophagy inducer, CR promotes and anticipates Schwann cell autophagy via AMP-activated protein kinase (AMPK) that facilitates remyelination in peripheral nerve. In summary, we provide new evidence for the role of autophagy in glucose metabolism and identify in energy depletion by dietary restriction a therapeutic approach in the fight against neuropathic pain.

Abstract
INTRODUCTION Breast cancer affects 1 in 10 women worldwide, and mastectomy is a cause of chronic pain with neuropathic characteristics. N-methyl-D-aspartate receptor (NMDAR) antagonists such as ketamine, memantine, dextromethorphan or magnesium are used to treat refractory pain by blocking NMDAR. Oral memantine has been shown to prevent postmastectomy pain and cognitive impact and to maintain quality of life. Likewise, the present study is intended to assess the preventive effect of oral magnesium, administered ahead of mastectomy, on the development of neuropathic pain. As a physiological blocker of NMDAR, magnesium could be an interesting candidate to prevent postoperative pain and associated comorbidities, including cognitive and emotional disorders, multiple analgesic consumption and impaired quality of life. METHODS AND ANALYSIS A randomised double-blind controlled clinical trial (NCT03063931) will include 100 women with breast cancer undergoing mastectomy at the Oncology Hospital, Clermont-Ferrand, France. Magnesium (100 mg/day; n=50) or placebo (n=50) will be administered for 6 weeks, starting 2 weeks before surgery. Intensity of pain, cognitive and emotional function and quality of life will be assessed by questionnaires. The primary endpoint is pain intensity on a 0-10 numerical rating scale at 1 month postmastectomy. Data analysis will use mixed models; all tests will be two-tailed, with type-I error set at α=0.05. ETHICS AND DISSEMINATION The study protocol and informed consent form were approved in December 2016 by the French Research Ethics Committee (South East VI Committee). Results will be communicated in various congresses and published in international publications. TRIAL REGISTRATION NUMBER NCT03063931.

Abstract
BACKGROUND Acute on chronic neuropathic pain is often refractory to analgesics and can be challenging to treat in the emergency department (ED). In addition, systemic medications such as opiates and nonsteroidal inflammatory drugs have risks, including hypotension and kidney injury, respectively. Difficulties in managing pain in patients with neuropathy can lead to prolonged ED stays, undesired admissions, and subsequent increased health care costs. CASE REPORT We describe the case of a 51-year-old woman who presented to the ED on two separate occasions for left forearm pain secondary to chronic ulnar neuropathy. During her first ED visit, the patient received multiple rounds of intravenous opiates and required hospital admission, which was complicated by opiate-induced hypotension. During her second visit, she underwent an ultrasound-guided ulnar nerve block performed by the emergency physician; her pain resolved and she was discharged home. WHY SHOULD EMERGENCY PHYSICIANS BE AWARE OF THIS?: Ultrasound-guided nerve blocks are an effective, safe, and relatively inexpensive alternative to opioids. Our case demonstrates that emergency providers may be able to perform ultrasound-guided regional anesthesia to treat an acute exacerbation of chronic neuropathic pain.
