BACKGROUND: Oxaliplatin, a widely used anticancer drug against metastatic colorectal cancer, can induce acute peripheral neuropathy, which is characterized by cold and mechanical allodynia. Activation of glial cells (e.g. astrocytes and microglia) and increase of pro-inflammatory cytokines (e.g. IL-1β and TNF-α) in the spinal cord play a crucial role in the pathogenesis of neuropathic pain. Our previous study demonstrated that Gyejigachulbu-Tang (GBT), a herbal complex formula, alleviates oxaliplatin-induced neuropathic pain in rats by suppressing spinal glial activation...

Chao Liu, Lei Chu, Hao-Chuan Yong, Liang Chen, Zhong-Liang Deng
BACKGROUND: Percutaneous endoscopic lumbar discectomy (PELD) has been growing in popularity for the treatment of lumbar disc herniation (LDH) due to its irreplaceable advantages over conventional open surgery. Compared with common lumbar disc herniations, discectomy of highly migrated LDH by PELD is known to be very difficult. Highly migrated lumbar disc herniation has long been a challenge for its specific characteristics. Three approaches for PELD have been applied to access a highly migrated LDH, including an interlaminar approach (IL), transforaminal approach (TF), and contralateral transforaminal approach (CTF)...

Chang Il Choi, Kyung Chae Park, Tae Ho Lee, Young Kwon Hong
BACKGROUND/PURPOSE: The purpose of the study was to determine if testicular delivery during microsurgical subinguinal varicocelectomy (MSV) reduces varicocele recurrence rates in pediatric patients. Testicular delivery during MSV enables ligation of the gubernacular veins, which is thought to reduce the likelihood of varicocele recurrence. However, recent studies have suggested that testicular delivery during MSV does not offer any beneficial effect and, therefore, may be optional or unnecessary...

BACKGROUND: Cholangiocarcinoma (CCA) is one of the most fatal malignant tumors with increasing incidence, mortality, and insensitivity to traditional chemo-radiotherapy and targeted therapy. Chimeric antigen receptor-modified T cell (CART) immunotherapy represents a novel strategy for the management of many malignancies. However, the potential of CART therapy in treating advanced unresectable/metastatic CCA is uncharted so far. CASE PRESENTATION: In this case, a 52-year-old female who was diagnosed as advanced unresectable/metastatic CCA and resistant to the following chemotherapy and radiotherapy was treated with CART cocktail immunotherapy, which was composed of successive infusions of CART cells targeting epidermal growth factor receptor (EGFR) and CD133, respectively...

Cheng Wang, Congpin Wang
Neuropathic pain is still considered as incurable disease as current therapies are not ideal in terms of efficacy and tolerability. It is imperative to search for novel drugs to obtain better treatments. Sulforaphane (SFN), a derivative of glucoraphanin present in cruciferous vegetables, exhibits therapeutic effects on inflammation-related diseases. Since inflammation plays an important role in regulating chronic pain, in the present study, we investigated anti-nociceptive effects of SFN and its underlying mechanisms in a neuropathic pain mouse model, sciatic nerve chronic constriction injury (CCI)...

BACKGROUND: Morphine is an opioid analgesic used to relieve moderate-to-severe pain, including pain in neonates at the intensive care unit. In our previous study, we showed that repeated morphine exposure during early life could trigger long-lasting implications on the developing nervous system, such as long-term neurochemical and behavioral alterations in adult rats. AIMS: The aim of our study was to determine the short-, intermediate-, and long-term effects of repeated morphine administration during early life on the thermal and mechanical thresholds and on the central levels (cerebral cortex and brainstem) of neurotrophins (brain-derived neurotrophic factor [BDNF] and nerve growth factor [NGF]) and cytokines (interleukin-6 [IL-6] and IL-10)...

Bone cancer pain (BCP) is one of the most difficult and intractable tasks for pain management, which is associated with spinal 'neuron-astrocytic' activation. The activation of the c-Jun N-terminal kinase (JNK)/chemokine (C-C motif) ligand (CCL2) signaling pathway has been reported to be critical for neuropathic pain. Rolipram (ROL), a selective phosphodiesterase 4 inhibitor, possesses potent anti-inflammatory and anti-nociceptive activities. The present study aimed to investigate whether the intrathecal administration of ROL has an analgesic effect on BCP in rats, and to assess whether the inhibition of spinal JNK/CCL2 pathway and astrocytic activation are involved in the analgesic effects of ROL...

A growing body of evidence indicates that prenatal alcohol exposure (PAE) may predispose individuals to secondary medical disabilities later in life. Animal models of PAE reveal neuroimmune sequelae such as elevated brain astrocyte and microglial activation with corresponding region-specific changes in immune signaling molecules such as cytokines and chemokines. The aim of this study was to evaluate the effects of moderate PAE on the development and maintenance of allodynia induced by chronic constriction injury (CCI) of the sciatic nerve in adult male rat offspring...

Thermal melting and re-cooling of AuIB, a neurotoxic conopeptide and a highly potent non-addictive pain reliever is investigated thoroughly in water and an ionic liquid (IL) 1-butyl-3-methylimidazolium Chloride, [Im41 ][Cl] by classical molecular dynamics simulations. Structural evolution of AuIB in water and the IL is observed at different temperatures between 305-400 K, to explore how highly viscous ionic solvents affect the peptide structure as compared to conventional solvent water. At 305 K, unlike water, the coercive effect of IL frustrates AuIB secondary structural motifs significantly...
