Digoxin protects against intervertebral disc degeneration via TNF/NF- κB and LRP4 signaling
ConclusionThese findings suggest that digoxin may be a potential therapeutic agent for intervertebral disc degeneration through anti-catabolism and pro-anabolism. Digoxin might also work as an alternative for other inflammation-related diseases.

Suppression of microglial Ccl2 reduces neuropathic pain associated with chronic spinal compression
ConclusionDisc microglia expressing high levels of Ccl2 may contribute to chronic spinal compression and SCI-associated pain. Therapeutically targeting Ccl2 in microglia could offer a potential avenue for treating chronic spinal compression and SCI-associated pain.

Nrf2/HO-1 signaling pathway participated in the protection of hydrogen sulfide on neuropathic pain in rats.
Abstract Neuropathic pain is evoked by aberrant sensory processing in the peripheral or central nervous system, which is characterized by persistent pain, tactile allodynia, or hyperalgesia. Neuroinflammation is associated with the initiation and maintenance of persistent pain in both the peripheral and central nervous systems. Hydrogen sulfide plays important regulatory roles in different physiological and pathological conditions. Therefore, we investigated the effect of hydrogen sulfide on allodynia, hyperalgesia and cytokine release in rats with neuropathic pain and the related regulatory mechanism. Neuropathic...

Dihydroartemisinin derivative DC32 inhibits inflammatory response in osteoarthritic synovium through regulating Nrf2/NF- κB pathway.
In conclusion, DC32 inhibited the inflammatory response in osteoarthritic synovium through regulating Nrf2/NF-κB pathway and attenuated OA. In this way, DC32 may be a potential agent in the treatment of OA. PMID: 31228817 [PubMed - as supplied by publisher]

Cannabinoid Receptor 2 Agonist JWH-015 Inhibits Interleukin-1 β-Induced Inflammation in Rheumatoid Arthritis Synovial Fibroblasts and in Adjuvant Induced Arthritis Rat via Glucocorticoid Receptor
Management of pain in the treatment of rheumatoid arthritis (RA) is a priority that is not fully addressed by the conventional therapies. In the present study, we evaluated the efficacy of cannabinoid receptor 2 (CB2) agonist JWH-015 using RA synovial fibroblasts (RASFs) obtained from patients diagnosed with RA and in a rat adjuvant-induced arthritis (AIA) model of RA. Pretreatment of human RASFs with JWH-015 (10-20 µM) markedly inhibited the ability of pro-inflammatory cytokine interleukin-1β (IL-1β) to induce production of IL-6 and IL-8 and cellular expression of inflammatory cyclooxygenase-2 (COX-2). JWH-015 was effe...

Allopurinol-induced Sweet's syndrome.
We describe the case of an 87-year-old woman with hyperuricemia who developed classic Sweet's syndrome manifestations 8 days after being treated with allopurinol. Patient's symptoms included fever, painful edema in the hands and lower limbs with non-pruritic erythematous plaques topped by pus-filled skin blisters, right eye conjunctivitis, splenomegaly and joint pain. At the emergency department, blood tests showed neutrophilic leukocytosis, inflammatory state and altered liver function. During hospitalization, she received unsuccessful treatments with two different antibiotics (namely ceftriaxone and levofloxacin), while ...
