Abstract
STUDY DESIGN Literature review. OBJECTIVES To review biomarkers in patients with ossification of the spinal ligament (OSL), including ossification of the posterior longitudinal ligament and ossification of the ligamentum flavum and to raise the present issues. METHODS A literature search was performed using PubMed and MEDLINE databases. The biomarkers were classified according to category. The number of the subjects and reproducibility were assessed. RESULTS Eleven articles were included in this review. There were 9 articles from Japan, 1 article from Taiwan, and 1 article from China. The biomarkers were classified into calcium-phosphate metabolism markers, bone turnover markers, sclerostin, dickkopf-1, secreted frizzled-related protein-1, fibroblast growth factor-23, fibronectin, menatetrenone, leptin, pentosidine, and hypersensitive C-reactive protein. However, there were several limitations in the research studies, such as small research field, small number of subjects, and a lack of reproducibility. CONCLUSIONS Although there have been several studies that have analyzed biomarkers for OSL, there are no definitive conclusions to date. Numerous issues will need to be resolved in the future. It is imperative to continue this research because the results might prove beneficial to elucidate the pathology of OSL and the measures to prevent the initiation and progression of the disease.

Abstract
Several reports have indicated a possible link between decreasing plasma levels of vitamin K and bone mineral density. It has been suggested that intestinal bacteria contribute to maintenance of vitamin K. Several factors are involved in the reduction of vitamin K in patients with Crohn’s disease (CD). We aimed to assess the relationship between gut microbiota and alternative indicators of vitamin K deficiency in patients with CD. We collected the feces of 26 patients with clinically inactive CD. We extracted 16S rRNA from the intestinal bacteria in the feces and amplified it by polymerase chain reaction. The generated polymerase chain reaction product was analyzed using a 16S metagenomic approach by Illumina Miseq platform. Serum undercarboxylated osteocalcin concentration was used as an alternative indicator of vitamin K deficiency. There was a significant negative correlation between serum undercarboxylated osteocalcin and mean Chao1 index in cases of low activity. The diversity of the gut microbiota was significantly lower, and Ruminococcaceae and Lachnospiraceae were significantly decreased in the vitamin K-deficient group in comparison to the vitamin K-normal group. Taken together, these data suggested the significance of investigating the gut microbiota even in patients with clinically inactive CD for improving patients’ vitamin K status.

Osteoporos Int 2019; 30:1175-1186. [PMID: 30734066 DOI: 10.1007/s00198-019-04853-7] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/02/2018] [Accepted: 01/13/2019] [Indexed: 02/06/2023]
Abstract
UNLABELLED In our systematic review and meta-analysis, we comprehensively evaluated menatetrenone in the management of osteoporosis. We found that menatetrenone decreased the ratio of undercarboxylated osteocalcin to osteocalcin (ucOC/OC) and improved lumbar BMD compared with placebo based on the 18 studies assessed. However, its benefit in fracture risk control was uncertain. INTRODUCTION We performed a systematic review and meta-analysis of the efficacy and safety of menatetrenone in managing osteoporosis. METHODS PubMed, Cochrane Library, Embase, ClinicalTrials.gov , and three Chinese literature databases (CNKI, CBM, Wanfang) were searched for relevant randomized controlled trials (RCTs) published before October 5, 2017, comparing menatetrenone with other anti-osteoporotic drugs or placebo in treating osteoporosis. The pooled risk ratio (RR) or mean difference (MD) and 95% confidence interval (CI) were calculated using fixed-effects or random-effects meta-analysis. RESULTS Eighteen RCTs (8882 patients) were included. Pooled analyses showed that menatetrenone was more effective than placebo in improving lumbar bone mineral density (BMD) (five studies, N = 658, MD = 0.05 g/cm2, 95% CI 0.01 to 0.09 g/cm2) and decreasing ucOC/OC (two studies, N = 75, MD = - 21.78%, 95% CI - 33.68 to - 9.87%). Compared with placebo, menatetrenone was associated with a nonsignificantly decreased risk of vertebral fracture (five studies, N = 5508, RR = 0.87, 95% CI 0.64 to 1.20). Evidence on other anti-osteoporotic drugs as comparators was limited and revealed no significantly different effects of menatetrenone on BMD or fracture risks. Furthermore, compared with placebo, menatetrenone significantly increased the incidence of adverse events (AEs) (two studies, N = 1949, RR = 1.47, 95% CI 1.07 to 2.02) and adverse drug reactions (four studies, N = 6102, RR = 1.29, 95% CI 1.07 to 1.56). However, no significant difference in the incidence of serious AEs was found between menatetrenone and placebo. CONCLUSIONS Menatetrenone significantly decreases ucOC and might improve lumbar BMD in osteoporotic patients. However, its benefit in fracture risk control is uncertain.

Abstract
BACKGROUND Warm needle acupuncture (WNA) is commonly used in primary osteoporosis (OP) management in China. The evidence of its effectiveness needs to be systematically reviewed. OBJECTIVE The aim of the meta-analysis was to evaluate whether using WNA alone or combined with conventional medicine benefits primary OP. METHODS PubMed, Embase, the Cochrane Central Register, Medline, China National Knowledge Infrastructure, Wanfang and VIP databases were searched from their inception through 30 June 2016. RCTs applying WNA independently or as an adjunct to conventional medicine, compared with conventional medicine alone, were included. Primary outcomes were bone mineral density (BMD) of the lumbar vertebrae, femoral neck, Ward's triangle and greater trochanter. The secondary outcome was chronic pain measured by VAS score. Meta-analysis was conducted using RevMan V.5.3 software. RESULTS Nine RCTs involving 572 participants were included. When WNA was used as an adjunct to conventional medicine, meta-analysis revealed a statistical difference in favour of increasing BMD of the lumbar vertebrae (mean difference (MD)=0.06, 95% CI 0.03 to 0.08, P<0.001). WNA increased BMD of the femoral neck (MD 0.14, 95% CI 0.08 to 0.21, P<0.001) and greater trochanter (MD 0.09, 95% CI 0.04 to 0.15, P<0.001) when used alone, and additionally decreased VAS scores (MD=-1.10, 95% CI -1.14 to -1.06, P<0.001) when used as an adjunct to conventional medicine. However, the safety of WNA was not specifically reported. CONCLUSIONS WNA may have beneficial effects on BMD and VAS scores of patients with primary OP. However, all included trials were at high risk of bias and of low quality. Further rigorous studies are needed to determine the effectiveness of WNA for primary OP treatment.

JOURNAL OF ETHNOPHARMACOLOGY 2017; 198:64-72.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Postmenopausal osteoporosis is the most common bone disease worldwide. Information concerning the effects of herbal medicines on mesenchymal cell osteogenesis and senescence remains lacking. AIM OF THIS STUDY This study was designed to investigate the effects of Du-Huo-Ji-Sheng-Tang (DHJST), a Chinese herbal medicine and its active component Ligusticum chuanxiong on osteogenic differentiation and the aging process of human mesenchymal cells (hMSCs). MATERIALS & METHODS hMSCs were used as in vitro model and osteogenesis was induced by administration of either osteogenesis inducing medium (OIM) or dexamethasone-depleted OIM (DDOIM) for 1-week or 2 weeks and the results were evaluated by measuring the formation of mineralization nodules. The effects of the compound recipe DHJST and its active component L. chuanxiong on hMSCs osteogenesis-related gene expression was determined by real-time PCR that targeted bone morphogenetic protein-2 (BMP2), RUNX2, ALP, COL-1, osteopontin (OPN), and osteocalcin (OCN). Antibodies against BMP-related signaling pathway proteins, such as BMP-2, ERK, SMAD 1/5/8, and RUNX2, were also detected at the protein level by Western blotting. Finally, the cumulative growth curve and senescence of the hMSCs were evaluated in order to assess the aging process. RESULTS L. chuanxiong increased osteogenic activity in hMSCs and up-regulated BMP-2 and RUNX2 gene expression via the activation of SMAD 1/5/8 and ERK signaling. Furthermore DHJST also showed a trend towards promoting the same effects in the same system. In the absence of dexamethasone, DHJST did activate SMAD 1/5/8 and ERK signaling and hence increased RUNX2 protein expression in hMSCs. In addition, both DHJST and L. chuanxiong delayed the hMSCs aging process by decreasing cell senescence. CONCLUSIONS We concluded that DHJST and its active component L. chuanxiong are able to promote osteogenic activity and decrease hMSCs senescence as cells age.

Abstract
SCOPE The potential benefit of vitamin K as a therapeutic in osteoporosis is controversial and the vitamin K regimen being used clinically (45 mg/day) employs doses that are many times higher than required to ensure maximal gamma-carboxylation of the vitamin K-dependent bone proteins. We therefore tested the hypothesis that vitamin K catabolites, 5-carbon (CAN5C) and 7-carbon carboxylic acid (CAN7C) aliphatic side-chain derivatives of the naphthoquinone moiety exert an osteotrophic role consistent with the treatment of osteoporosis. METHODS AND RESULTS Osteoblast-like MG63 cell cultures were challenged with lipopolysaccharide and the levels of interleukin-6, an osteoclastogenic cytokine, measured with and without catabolites; low concentrations of CAN7C significantly inhibited interleukin-6 release, but CAN5C did not. In models of bone loss induced by ovariectomy or sciatic neurectomy in C57BL/6 mice, we found that the rarer CAN7C catabolite markedly restricted ovariectomy-induced bone loss and possibly limited sciatic neurectomy-induced bone loss. CAN7C activity depends on a free carboxylic acid and its particular side-chain structure. CONCLUSION These in vivo data indicate for the first time that the clinical utility of vitamin K for osteoporosis may reside in an unusual catabolite.
