Osteonecrosis of the jaw to a certain extent has been with us for many years. But recently the advent of various medications such as bisphosphonates, VEGF inhibitors, tyrosine kinase inhibitors and humanized antibodies to osteoclastic action have resulted in thousands of cases. While the bisphosphonates continue to be the most common medication associated with osteochemonecrosis antibodies such as denosumab which irreversibly act on osteoclastic action are also being reported. This narrative review will serve as an update with a focus on some of the histopathologic features discussed and reviewed. Perhaps even more uncommonly seen in past reports a discussion of features possibly observed while grossing specimens will be discussed. At the end of this report is hoped that the pathologist will have a better understanding of the historical features, clinical settings, gross examination features as well as histopathologic features associated with osteochemonecrosis.

Ligustilide, a phthalide compound extracted from Umbelliferae plants such as Angelica sinensis and Ligusticum chuanxiong, has been proven to possess various pharmacological activities, such as anti-inflammatory, anti-tumor, anti-atherosclerosis, anti-ischemic stroke injury, and anti-Alzheimer's disease properties. In recent years, it has shown great potential, particularly in the treatment of locomotor system diseases. Studies have shown that ligustilide has significant therapeutic effects on various locomotor system diseases, including osteoporosis, osteoarthritis, femoral head necrosis, osteosarcoma, and muscle aging and injury.

Indole-3-propionic acid (IPA), a metabolite produced by gut microbiota through tryptophan metabolism, has recently been identified as playing a pivotal role in bone metabolism. IPA promotes osteoblast differentiation by upregulating mitochondrial transcription factor A (Tfam), contributing to increased bone density and supporting bone repair. Simultaneously, it inhibits the formation and activity of osteoclasts, reducing bone resorption, possibly through modulation of the nuclear factor-κB (NF-κB) pathway and downregulation of osteoclast-associated factors, thereby maintaining bone structural integrity.

Objective: Ensuring adequate bone health is crucial for preventing conditions such as osteoporosis and fractures. Zingerone, a phytonutrient isolated from cooked ginger, has gained attention for its potential benefits in bone health. This study evaluated the osteoprotective potential of zingerone and its effects on differentiation and signalling pathways using SAOS-2 osteosarcoma and RAW264.

Triptolide (TP) is the primary pharmacological component of Tripterygium Glycosides (TG), which has anti-inflammatory, antiproliferative, and immunosuppressive properties, among other pharmacological actions, and has excellent potential for developing into a new DMARD. We have reviewed the effects and mechanisms of TP on immunosuppression, inhibiting synovial proliferation, and preventing articular bone destruction in the treatment of rheumatoid arthritis (RA), which is a common disease in the elderly in this paper. We have found that TP has regulatory effects on multiple vital cells in the above-mentioned pathological process of RA, such as monocytes/macrophages, dendritic cells, T cells, fibroblast-like synoviocytes, and osteoclasts.

Bones possess metabolic activity, with their homeostasis maintained by bone resorption and bone formation mediated by osteoclasts and osteoblasts. By measuring bone metabolism markers, the overall state of bone metabolism and dynamic changes in systemic bone tissue can be reflected. Traditional bone turnover markers, including alkaline phosphatase, bonespecific alkaline phosphatase, procollagen type 1 N-terminal propeptide, procollagen type 1 C-terminal propeptide, osteocalcin, c-terminal telopeptides of type 1 collagen(CTX) and its subtype β-CTX, n-terminal telopeptides of type 1 collagen, have been widely used in clinical practice but still have limitations in terms of stability, diagnostic reliability, and specific reflection of bone sites.
