Abstract
Higher sensitivity to pain is a common clinical symptom in postmenopausal females. The gut microbiota (GM) has recently been identified as participating in various pathophysiological processes and may change during menopause and contribute to multiple postmenopausal symptoms. Here, we investigated the possible correlation between GM alteration and allodynia in ovariectomized (OVX) mice. Results showed that OVX mice exhibited allodynia from 7 weeks after surgery compared with sham-operated (SHAM) mice by comparing pain-related behaviors. Fecal microbiota transplantation (FMT) from OVX mice induced allodynia in normal mice while FMT from SHAM mice alleviated allodynia in OVX mice. Microbiome 16S rRNA sequencing and linear discriminant analysis revealed alteration of the GM after OVX. Furthermore, Spearman's correlation analysis showed associations between pain-related behaviors and genera, and further verification identified the possible pain-related genera complex. Our findings provide new insights into the underlying mechanisms of postmenopausal allodynia, and suggest pain-related microbiota community as a promising therapeutic target. PERSPECTIVE: This article provided the evidence of gut microbiota playing essential roles in postmenopausal allodynia. This work intended to offer a guidance for further mechanism investigation into gut-brain axis and probiotics screening for postmenopausal chronic pain.

Abstract
Background/purpose: To evaluate and compare the effects of parathyroid hormone analogues, receptor activators of nuclear factor kappa-B ligand inhibitors and bisphosphonates on the quality of life of postmenopausal women. Methods: A prospective observational study of 23 matched postmenopausal women was conducted with propensity score analysis on quality of life at one-year follow-up. Visual analogue scale for back pain and outcome scores were carried out as the quality of life or treatment adherence measurements. Results: Teriparatide use was associated with significant improvements in visual analogue scale, EuroQol 5-level 5-dimension general health status and Osteoporosis Assessment Questionnaire physical function, whereas denosumab and alendronate groups only demonstrated improved Osteoporosis Assessment Questionnaire scores but worsened back pain. Baseline average visual analogue scale back pain predicted one-year average back pain progression (partial eta squared = 0.617, p = 0.001). Conclusions: One-year continuous teriparatide treatment is most effective in improving quality of life outcomes in postmenopausal osteoporotic women. Baseline average visual analogue scale back pain remained the only predictive factor for one-year back pain progression.

Abstract
Osteosarcopenia (OSP) is a geriatric syndrome characterized by the coexistence of osteoporosis and sarcopenia and associated with an increased risk of fragility fractures, disability, and mortality. For patients with this syndrome, musculoskeletal pain represents the most significant challenge since, in addition to limiting the individual's functionality and promoting disability, it has a huge psychological burden involving anxiety, depression, and social withdrawal. Unfortunately, the molecular mechanisms involved in the development and persistence of pain in OSP have not yet been fully elucidated, although immune cells are known to play a key role in these processes. Indeed, they release several molecules that promote persistent inflammation and nociceptive stimulation, resulting in the gating of ion channels responsible for the generation and propagation of the noxious stimulus. The adoption of countermeasures to counteract the OSP progression and reduce the algic component appears to be necessary, providing patients with a better quality of life and greater adherence to treatment. In addition, the development of multimodal therapies, based on an interdisciplinary approach, appears to be crucial, combining the use of anti-osteoporotic drugs with an educational programme, regular physical activity, and proper nutrition to eliminate risk factors. Based on this evidence, we conducted a narrative review using the PubMed and Google Scholar search engines to summarize the current knowledge on the molecular mechanisms involved in the pain development in OSP and the potential countermeasures to be taken. The lack of studies addressing this topic highlights the need to conduct new research into the resolution of an ever-expanding social problem.

Strontium ion attenuates osteoarthritis through inhibiting senescence and enhancing autophagy in fibroblast-like synoviocytes. Mol Biol Rep 2023; 50:1437-1446. [PMID: 36472726 DOI: 10.1007/s11033-022-08112-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2022] [Accepted: 11/09/2022] [Indexed: 12/12/2022]
Abstract
Osteoarthritis (OA) mainly occurs in the elderly population and seriously affects their quality of life (QOL). Strontium (Sr) ions have shown positive effects on bone tissue and are promising for OA treatment. However, the adequate treatment dosage and underlying mechanisms are unclear. This study investigated the effects and underlying mechanisms of different concentrations of Sr ions in a mouse model of OA induced by destabilization of the medial meniscus (DMM) surgery. DMM-induced OA mice received intra-articular injections of different concentrations of Sr ions, and a suitable concentration of Sr ions was found to improve OA. Furthermore, we investigated the mechanism by which Sr ions mediate senescence and autophagy in fibroblast-like synoviocytes (FLSs) in the synovial tissues of DMM-induced OA mice. OA mice treated with 10 µl of 5 mmol/L SrCl2 showed the greatest improvement in pain-related behavior and cartilage damage. In addition, in vivo and in vitro experiments revealed that Sr ions inhibit senescence and improve the autophagic function of FLSs. We also found that enhancement of the autophagic function of FLSs could effectively slow down senescence. Therefore, we show that Sr ions through the AMPK/mTOR/LC3B-II signal axis improve FLSs autophagy function and delay FLSs senescence, and furthermore, improve OA. These results suggest that senescence and autophagy function of FLSs may serve as promising targets for OA treatment, and that Sr ions may inhibit OA progression through these two targets.

Abstract
This study aimed to evaluate skeletal pain associated with osteoporosis and to examine the inhibitory effects of cytotoxic T lymphocyte-associated antigen-4Ig (CTLA-4Ig) administration in ovariectomized (OVX) mice. Eight-week-old female ddY mice were assigned to three groups: sham-operated mice (SHAM) treated with vehicle, OVX mice treated with vehicle (OVX), and OVX mice treated with CTLA-4Ig (CTLA-4Ig). Vehicle or CTLA-4Ig was injected intraperitoneally, starting immediately after surgery. After 4 weeks of treatment, mechanical sensitivity was examined, and the bilateral hind limbs were removed and evaluated by micro-computed tomography, immunohistochemical analyses, and messenger RNA expression analysis. Ovariectomy induced bone loss and mechanical hyperalgesia in the hindlimbs. CTLA-4Ig treatment prevented bone loss in the hindlimbs compared to vehicle administration in the OVX group. Moreover, mechanical hyperalgesia was significantly decreased in the CTLA-4Ig treatment group in comparison to the OVX group. The expression levels of tumor necrosis factor-α (TNF-α) and sclerostin (SOST), as well as the number of osteoclasts, were increased, and the expression level of Wnt-10b was decreased in the OVX group compared with the SHAM group, whereas these parameters were improved in the CTLA-4Ig group compared with the OVX group. The novelty of this research is that CTLA-4Ig administration prevented bone loss and mechanical hyperalgesia induced by ovariectomy in the hindlimbs.

Abstract
Severe bone damage from diseases, including extensive trauma, fractures, and bone tumors, cannot self-heal, while traditional surgical treatment may bring side effects such as infection, inflammation, and pain. As a new biomaterial with controllable mechanical properties and biocompatibility, hydrogel is widely used in bone tissue engineering (BTE) as a scaffold for growth factor transport and cell adhesion. In order to make hydrogel more suitable for the local treatment of bone diseases, hydrogel preparation methods should be combined with synthetic materials with excellent properties and advanced technologies in different fields to better control drug release in time and orientation. It is necessary to establish a complete method to evaluate the hydrogel's properties and biocompatibility with the human body. Moreover, establishment of standard animal models of bone defects helps in studying the therapeutic effect of hydrogels on bone repair, as well as to evaluate the safety and suitability of hydrogels. Thus, this review aims to systematically summarize current studies of hydrogels in BTE, including the mechanisms for promoting bone synthesis, design, and preparation; characterization and evaluation methods; as well as to explore future applications of hydrogels in BTE.

Abstract
OBJECTIVES There are few reports on the comparison between teriparatide (PTH) and bisphosphonate (BP) in terms of osteoporosis pain-related behavior and immunohistochemical findings. The aims of this study were to evaluate skeletal pain associated with osteoporosis and to examine the inhibitory effect of PTH and BP on pain and bone loss in hind limb-unloaded (HU) mice. The mechanism of osteoporotic pain in HU mice was evaluated by examining pain-related behavior and immunohistochemical findings. The effects of PTH and alendronate (ALN), a potent osteoclast inhibitor, on these parameters were also assessed. METHODS Eight-week-old male ddY mice were tail-suspended for 2 weeks and assigned to four groups: hind limb-loaded (HL) mice with only tail suspension treated with vehicle; HU mice with tail suspension treated with vehicle; HU mice treated with PTH; and HU mice treated with ALN. Starting immediately after reloading, vehicle, PTH, or ALN was injected subcutaneously. After a 2-week treatment, mechanical sensitivity was examined using von Frey filaments. Bilateral hind limbs were removed for micro-computed tomography, immunohistochemical analysis, and messenger RNA (mRNA) expression analysis. RESULTS HU mice with tail suspension developed bone loss and mechanical hyperalgesia in the hind limbs. The HU mice showed an increased osteoclasts and sclerostin-positive cells in the hind limb bone. Furthermore, PTH and ALN both prevented HU-induced bone loss and mechanical hyperalgesia in the osteoporotic animal models. Histological examination of the hind limb bone revealed that, similar to ALN, PTH inhibited the osteoclasts and sclerostin-positive cells. The mRNA levels of TNFα and IL-6 tended to decrease with ALN or PTH treatment compared with those without any treatment. CONCLUSIONS Treatment with PTH as well as BP prevented bone loss, mechanical hyperalgesia, osteoclast increase, and osteocyte increase. Similar to BP, the inhibitory effect of PTH on osteoclasts might contribute to the improvement of skeletal pain.
