Abstract
Phytochemical study on Euphorbia milii, a common ornamental plant, resulted in the identification of thirteen new ent-rosane diterpenoids (1-13), three new ent-atisane diterpenoids (14-16), and a known ent-rosane (17). Their structures were delineated using spectroscopic data, quantum chemical calculations, and X-ray diffraction experiments. Euphomilone F (1) represented a rare ent-rosane-type diterpenoid with a 5/7/6 skeleton. Euphoainoid G (8) was a rare rosane diterpenic acid. Compounds 9 and 10 carried infrequent tetrahydrofuran rings, and compounds 11-13 was 18-nor-ent-rosane diterpenoids. All isolates were evaluated for their inhibitory effects on RANKL-induced osteoclasts. Notably, compounds with aromatic ester groups (2-7) showed promising activities (IC50 < 10 μM), underscoring the significance of acylated A-ring moieties in the ent-rosane skeleton for anti-osteoclastogenesis. Thirteen synthetic derivatives were obtained through esterification of 17. Of these, compound 27 exhibited remarkable improvement, with an IC50 of 0.8 μM, more than a 12-fold increase in potency compared to the parent compound 17 (IC50 > 10 μM). This work presents a series of new ent-rosane diterpenoids with potential antiosteoporosis agents.

Abstract
Citrisorbicillinol (1), along with six other known compounds (2-7), was isolated from an endphyte Penicillium citrinum ZY-2 of Plantago asiatica L. Citrisorbicillinol (1) was characterized as a skeletally unprecedented hybrid sorbicillinoid, and its unique framework is likely formed by intermolecular [4 + 2] cycloaddition between intermediates derived from citrinin and sorbicillinoid biosynthetic gene clusters. Compounds 1 and 2 demonstrated to promote osteoblastic differentiation in MC3T3-E1 cells, and to be osteogenic in the prednisolone induced osteoporotic zebrafish. Compounds 3-7 exhibited moderate cytotoxicity against four human cancer cell lines.

Abstract
Thirteen new sirenin derivatives named eupenicisirenins C-O (1-13), along with a biosynthetically related known one (14), were isolated from the mangrove sediment-derived fungus Penicillium sp. SCSIO 41410. The structures, which possessed a rare cyclopropane moiety, were confirmed by extensive analyses of the spectroscopic data, quantum chemical calculations, and X-ray diffraction. Among them, eupenicisirenin C (1) exhibited the strongest NF-κB inhibitory activities, as well as suppressing effects on cGAS-STING pathway. Moreover, 1 showed the significant inhibitory effect on RANKL-induced osteoclast differentiation in bone marrow macrophages cells, and also displayed the therapeutic potential on prednisolone-induced zebrafish osteoporosis. Transcriptome analysis and the following verification tests suggested that its anti-osteoporotic mechanism is related to the extracellular matrix receptor interaction-related pathways. This study provided a promising marine-derived anti-osteoporotic agent for the treatment of skeletal disease.

Abstract
In a previous study, we discovered that the ethanolic extract of sea buckthorn (Hippophae rhamnoides) fruits exhibited anti-osteoporosis effects both in vitro and in vivo. Through bioassay-guided fractionation, we identified the hexane fraction (HRH) as the active fraction, which was further fractionated using preparative HPLC. Among the resulting six fractions, HRHF4 showed significant activity. In the present study, we focused on the bioassay-guided isolation of bioactive compounds from the HRHF4 fraction. We successfully identified the active HRHF43 fraction, which led us to the isolation of potential bioactive compounds (1-6). The chemical structures of these compounds were determined using NMR data, LC-MS analysis, and HR-ESI-MS data as four triterpenes, ursolic acid (1), uvaol (2), oleanolic aldehyde (3), and ursolic aldehyde (4), together with two fatty acids, methyl linoleate (5) and ethyl oleate (6). To evaluate the efficacy of promoting osteoblast differentiation and the expression of mRNA biomarkers related to osteogenesis, we tested the isolated compounds in the mouse mesenchymal stem cell line, C3H10T1/2. Alkaline phosphate staining demonstrated that triterpenes (1-4) displayed osteogenic activity. Particularly noteworthy, ursolic aldehyde (4) exhibited the most potent effect, showing an 11.2-fold higher activity at a concentration of 10 μg/mL compared to the negative control. Moreover, ursolic aldehyde (4) upregulated the gene expression of bone formation-related biomarkers, including Runx2, Osterix, Alp, and Osteopontin. These findings suggest that the fruit extract of H. rhamnoides may have potential as a nutraceutical for promoting bone health, with ursolic aldehyde (4) identified as an active constituent.

Abstract
Marine fungi are prolific source for the discovery of structurally diverse and bioactive molecules. In our search for new anti-osteoporosis compounds from deep-sea-derived fungi, we prioritized a fungus whose extract exhibited moderate activity and rich chemical diversity. The investigation of this strain afforded a class of citrinins, including three new citrinin trimers, neotricitrinols A-C (1-3), and three known dimeric/monomeric precursors (4-6). Neotricitrinols A-C (1-3) feature a unique octacyclic carbon scaffold among the few reported citrinin trimers with their absolute configurations established by spectroscopic analysis, theoretical-statistical approaches (GIAO-NMR, TDDFT-ECD/ORD calculations), DP4+ probability analysis as well as biogenetic consideration. A plausible biosynthetic pathway linking 1-3 from the common intermediate metabolite penicitrinol A (4) was proposed. Biologically, neotricitrinol B (2) showed potential anti-osteoporosis activity by promoting osteoblastogenesis and inhibiting adipogenic differentiation on primary bone mesenchymal stem cells, while displaying no cytotoxicity.

Abstract
Desert-living Cistanche herb (DC), as a traditional Chinese medicine for tonifying kidney yang, is often used to treat postmenopausal osteoporosis (PMOP). Total phenylethanoid glycosides are instruction ingredients for discrimination and assay according to the China pharmacopoeia for DC. This research aimed to reveal the anti-osteoporosis mechanism of total phenylethanoid glycosides of DC (PGC) by transcriptomic analysis of ovariectomized rats. Serum levels of BGP were evaluated by ELISA, the bone weight was measured, and transmission electron microscopy was used to examine the ultrastructure of osteoblasts in rats. In addition, micro-CT was used to detect the bone volume (Tb.BS/BV), bone mineral density (Tb.BMD), and bone mineral content (Tb.BMC) in trabecular bone, and the ratio of cortical bone area to total area (Ct.ar/Tt.ar), and the level of bone mineral content (Ct.BMC) in cortical bone. Differential expressed genes (DEGs) after PGC treatment were analyzed by transcriptomics. Then, a bioinformatics analysis of DEGs was carried out through GO enrichment, KEGG enrichment, and selection of the nucleus gene through the protein-protein interaction network. Through qRT-PCR analysis, the DEGs were verified. The analysis results indicated that PGC increased the secretion of osteogenic markers, and ultrastructural characterization of osteoblasts and bone morphology were improved in ovariectomized rats. A total of 269 genes were differentially expressed, including 201 genes that were downregulated and 68 genes that were upregulated between the model group and the PGC group. Bioinformation analysis results prompt the conclusion that PGC could promote the bone metabolism by muscle cell development, myofibril assembly, etc. In addition, our study also found that PGC has a good effect on osteoporosis complicated with cardiomyopathy, and it also provided evidence for the correlation between sarcopenia and osteoporosis.

Abstract
BACKGROUND Cushing's syndrome is known as an important cause of secondary osteoporosis, characterized by reduction of bone mineral density and potential occurrence of fragility fractures before diagnosis in young population. Therefore, for young patients with fragility fractures, especially in young women, more attention should be paid on glucocorticoid excess caused by Cushing's syndrome, due to relatively higher rate of misdiagnosis, distinct pathological characteristics and different treatment strategies compared with violent fractures and primary osteoporosis related fractures. CASE PRESENTATION We presented an unusual case of a 26-year-old woman with multiple vertebral compression fractures and pelvis fractures, subsequently diagnosed as Cushing's syndrome. On admission, the radiographic results showed fresh second lumbar vertebra fracture, and old fourth lumbar vertebra and pelvic fractures. The dual energy X-ray absorptiometry of lumbar spine revealed marked osteoporosis, and her plasm cortisol was extremely high. Then, Cushing's syndrome, caused by left adrenal adenoma, was diagnosed by further endocrinological and radiographic examinations. After receiving left adrenalectomy, her plasma ACTH and cortisol values returned to normal level. In term of OVCF, we adopted conservative treatments, including pain management, brace treatment, and anti-osteoporosis measures. Three months after discharge, the patient's low back pain was in complete remission without new onset of pain, and returned to normal life and work. Furthermore, we reviewed the literatures on advancements in the treatment of OVCF caused by Cushing's syndrome, and based on our experiences, proposed some additional perspectives to guide treatment. CONCLUSION In term of OVCF secondary to Cushing's syndrome without neurological damage, we prefer systematic conservative treatments, including pain management, brace treatment, and anti-osteoporosis measures, to surgical treatment. Among them, anti-osteoporosis treatment has the highest priority because of the reversibility of osteoporosis caused by Cushing's syndrome.

Abstract
Fragility hip fracture (FHF) is a serious complication of osteoporosis. A fracture liaison service (FLS) is crucial in preventing FHF. Our retrospective data of 489 patients with FHF and 3-year follow-ups demonstrated that the FLS improved functional outcomes. Our study's mortality rates were lower than in other published series. PURPOSE This study assessed the 3-year outcomes after fragility hip fracture (FHF) treatment by a multidisciplinary team from the Siriraj Fracture Liaison Service (Si-FLS). The review investigated the administration rates of anti-osteoporosis medication, refracture, and mortality; activities of daily living; mobility; and health-related quality of life. METHODS A retrospective review was performed of the records of Si-FLS patients given FHF treatment between June 2016 and October 2018. The outcomes were evaluated at 3 time points: before discharge, and 1 and 3 years after treatment. RESULTS The study enrolled 489 patients (average age, 78). The mortality and refracture rates at 1 year after hip fracture were 13.9% and 1.6%, respectively. At the 3-year follow-up, both rates were higher (20.4% and 5.7%, respectively). The Barthel Index and EuroQoL Visual Analogue Scale had risen to a plateau at the 1-year follow-up and remained stable to the 3-year follow-up. One year after treatment, approximately 60% of the patients could ambulate outdoors, and the proportion remained steady until the 3-year follow-up. There was no difference in the 1- and 3-year follow-up anti-osteoporosis medication administration rates (approximately 40%). CONCLUSIONS This study confirms the benefits of having a multidisciplinary FLS care team to manage older people with FHF. An FLS improves the care of patients with FHF and the social support of caregivers and relatives. The FLS maintained the functional outcomes of the patients through 3 years of postfracture treatment.

Abstract
The high nutritional value and diverse functional properties of egg yolk proteins have led to its widespread use in the fields of food, medicine, and cosmetics. Various extraction methods have been reported to obtain the proteins from egg yolk, however, their utilization is limited due to the relatively low extraction efficiency and/or toxic solvents involved. Several simpler and greener technologies, especially physical fields (ultrasound), have been successfully developed to improve the extraction efficiency. The egg yolk proteins may exert multiple biological activities, enabling them to be a promising tool in improve human health and wellbeing, such as anti-obesity, anti-atherosclerosis, anti-osteoporosis, diagnosis and therapy for SARS-CoV-2 infections. This article summarizes the novel extraction technologies and latest applications of the egg yolk proteins in the recent 5 years, which should stimulate their utilization as health-promoting functional ingredients in foods and other commercial products.

Abstract
Excessive osteoclast differentiation and/or bone resorptive function causes a gradual loss of bone, leading to the pathogenesis of bone diseases such as osteoporosis (OP). In this study, a sulfated glucuronorhamnoxylan polysaccharide (designated SPS-CF) of the green alga Capsosiphon fulvescens was evaluated for anti-osteoporotic activity using osteoclastic cells differentiated from RAW264.7 macrophages by receptor activator of NF-κB ligand (RANKL) treatment and ovariectomized (OVX) female mice as a postmenopausal OP model. With negligible cytotoxicity, SPS-CF (50 μg/mL) significantly suppressed tartrate-resistant acid phosphatase (TRAP) activity, actin ring formation, and expression of matrix metalloproteinase 9 (MMP-9), cathepsin K, TRAF6, p-Pyk2, c-Cbl, c-Src, gelsolin, carbonic anhydrase II (CA II), and integrin β3, indicating that SPS-CF inhibits the differentiation and bone resorptive function of osteoclasts. Removal of sulfate groups from SPS-CF abolished its anti-osteoclastogenic activities, demonstrating that sulfate groups are critical for its activity. Oral administration of SPS-CF (400 mg/kg/day) to OVX mice significantly augmented the bone mineral density (BMD) and serum osteoprotegerin (OPG)/RANKL ratio. These results demonstrated that SPS-CF exerts significant anti-osteoporotic activity by dampening osteoclastogenesis and bone resorption via downregulation of TRAF6-c-Src-Pyk2-c-Cbl-gelsolin signaling and augmentation of serum OPG/RANKL ratios in OVX mice, suggesting that SPS-CF can be a novel anti-osteoporotic compound for treating postmenopausal OP.

Abstract
Although chondroitin sulfate calcium complex (CSCa) was claimed to have the bioactivity for bone care in vitro, its anti-osteoporosis bioactivity was little reported in vivo. Here, the effects of CSCa on osteoporosis rats were investigated. Results showed that, compared with the osteoporosis rats, CSCa could improve the bone mineral density and microstructure of femur, and change the bone turnover markers level in serum. 16S rRNA sequencing and metabolomics analysis indicated CSCa intervention altered the composition of gut microbiota along with metabolite profiles in ovariectomized rat faeces. The correlation analysis showed some gut microbiota taxa were significantly correlated with osteoporosis phenotypes and the enriched metabolites. Taken together, dietary CSCa intervention has the potential to alleviate the osteoporosis and related symptoms probably involving gut microbiota or the metabolite profiles as demonstrated in rats. This study provides some scientific evidence for the potential effects of CSCa as the food supplement on the osteoporosis.

Abstract
Achyranthes bidentata is a species of flowering plant that is mainly distributed in China. The A. bidentata rhizome is a famous traditional Chinese medicine that has been widely used to treat lumbago, arthritis, and bone hyperplasia. In this work, A. bidentata rhizome was isolated and purified to obtain a pectic polysaccharide (ABPB-4). Chemical and spectral analyses showed that ABPB-4 had a main chain of →4)-α-d-GalpA-(1→ and →2,4)-α-l-Rhap-(1→, and the branch chains included →4)-β-d-Galp-(1→, →6)-β-d-Galp-(1→, →3,6)-β-d-Galp-(1→, →5)-α-l-Araf-(1→ and →3,5)-α-l-Araf-(1→, and it was terminated with α-l-Araf-(1→ and β-d-Galp-(1→. At concentrations of 0.01, 0.02, and 0.04 μmol/L, ABPB-4 significantly promotes the proliferation, differentiation, and mineralization of MC3T3-E1 cells in vitro, and it appreciably enhances the mRNA expression levels of osteogenic-related genes in these cells. Overall, the results reported herein indicate that ABPB-4 has outstanding osteogenic activity, and that it may be used as an anti-osteoporosis agent in the future.

Abstract
AIM Due to on-going safety concerns or lack of efficacy of currently used medications for the treatment of osteoporosis (OP), identifying new therapeutic agents is an important part of research. In the present study, potential anti-osteoporotic activity of a natural flavonoid glycoside, trilobatin (phloretin 4-O-glucoside, Tri) was evaluated. MATERIAL AND METHODS Osteoclastic cells were established by treating the RAW264.7 macrophage cells with RANKL and ovariectomized (OVX) C57BL/6 female mice were used as an animal model of postmenopausal OP. Actin ring formation, expression levels of osteoclastogenic marker genes and bone resorptive proteins were measured by RT-PCR, western blot, or fluorometric assays. Bone mineral density (BMD) was determined by pDEXA densitometric measurement and serum osteoprotegerin (OPG) and RANKL were measured by ELISA. KEY FINDING Tri (5-20 μM) significantly inhibited osteoclast formation and actin ring formation in RANKL-induced osteoclasts. Tri attenuated expression of osteoclastogenic genes (MMP-9 and cathepsin K), bone resorptive proteins (CA II and integrin β3), and osteoclastogenic signalling proteins (TRAF6, p-Pyk2, c-Cbl, and c-Src). Oral administration of Tri to OVX mice augmented BMD and serum OPG/RANKL ratio. Interestingly, while Tri and phloretin aglycone (Phl) showed similar levels of in vitro anti-osteoclastogenic activity, Tri more potently ameliorated bone loss than Phl in OVX mice. SIGNIFICANCE This study demonstrated that Tri inhibits osteoclastic cell differentiation and bone resorption by down-regulating the expression of osteoclastogenic marker genes and signalling proteins, bone resorptive proteins, and by augmenting serum OPG/RANKL ratio, suggesting that Tri can be a novel anti-osteoporotic compound for treating senile and postmenopausal OP.

Abstract
Osteoporosis is a bone metabolic disease caused by the imbalance between osteoblasts and osteoclasts due to excess osteoclastogenesis, manifesting in the decrease of bone density and bone strength. Scutellariae Radix shows good anti-osteoporosis activity, but the effective component is still unclear. Cell membrane chromatography (CMC) is a biological affinity chromatography with membrane immobilized on a silica carrier as the stationary phase. It can realize a dynamical simulation of interactions between drugs and receptors on cell membrane, which is suitable for screening active compounds from complex systems. In this study, the components of Scutellariae Radix with potential anti-osteoporosis activity through inhibiting the differentiation from bone marrow mononuclear cells (BMMCs) to osteoclast were screened by a BMMC/CMC analytical system. Firstly, a new 3-mercaptopropyltrimethoxysilane (MPTS)-modified BMMC/CMC stationary phase was developed to realize covalent binding with cell membrane fractions. By investigating the retention time (tR) of the positive drug, the life span of the MPTS-modified CMC columns was significantly improved from 3 to 12 days. Secondly, 6 components of Scutellariae Radix were screened to show affinity to membrane receptors on BMMCs by a two-dimensional BMMC/CMC–TOFMS analytical system. Among them, tectochrysin demonstrated the best anti-osteoporosis effect in vitro, which has never been reported. We found that tectochrysin could inhibit the differentiation of BMMCs into osteoclasts induced by receptor activator of nuclear factor-κΒ ligand (RANKL) and macrophage colony-stimulating factor (M-CSF) in a concentration-dependent manner in vitro. In vivo, it significantly reduced the loss of bone trabeculae in ovariectomized mice, and decreased the level of C-terminal cross-linking telopeptides of type 1 collagen (CTX-1), tartrate-resistant acid phosphatase 5b (TRAP-5b), interleukin 6 (IL-6) in serum. In conclusion, tectochrysin serves as a potential candidate in the treatment of osteoporosis. The proposed two-dimensional MPTS-modified BMMC/CMC-TOFMS analytical system shows the advantages of long-life span and fast recognition ability, which is very suitable for infrequent cell lines.

Abstract
Cibotium barometz, an important traditional Chinese medicine, is used in strengthening bones and tendons. We found that C. barometz crude polysaccharides (CB70) could alleviate bone loss and markedly improve the biomechanical properties of OVX rats. Thus, to clarify biological active ingredient(s) of CB70, two homogeneous polysaccharides (CBP70-1-1 and CBP70-1-2) were purified from CB70. A combination of monosaccharide composition, FT-IR, GC-MS and NMR analysis indicated that CBP70-1-1 was composed of →6)-D-Galp-(1→, D-Glcp-(1→, →3,6)-D-Manp-(1→, →4)-D-Glcp-(1→ and →6)-D-Glcp-(1→ with relative molecular weights of 12,724 Da, and CBP70-1-2 was composed of →4)-D-Glcp-(1→, D-Glcp-(1→, →3,6)-D-Manp-(1→, →6)-D-Galp-(1→, →4,6)-D-Glcp-(1→ and →3)-L-Araf-(1→ with relative molecular weights of 3611 Da. Morphological analyses revealed that CBP70-1-1 and CBP70-1-2 appeared as a sheet that were irregular in size and shape, while the surface of CBP70-1-1 was full of sharp protuberances and CBP70-1-2 was smooth. Furthermore, the effects of CBP70-1-1 and CBP70-1-2 on the proliferation, differentiation and mineralization of mouse pre-osteoblastic MC3T3-E1 cells were assessed via CCK-8 assay, alkaline phosphatase activity assay, and alizarin red-based assay, respectively. These results revealed that CBP70-1-1 and CBP70-1-2 significantly promoted the proliferation, differentiation and mineralization of MC3T3-E1 cells, even better than E2. More importantly, quantitative real-time PCR and Western blot analysis indicated that CBP70-1-2 pronouncedly promoted the expression of osteogenic-related marker genes (Runx2, Osx, Ocn and Opn) and proteins (BMP2, RUNX2, OSX and p-SMAD1), which implies that the osteogenic activity of CBP70-1-2 is accomplished mainly by activating the BMP2/SMAD1 signaling pathway. These findings suggest CBP70-1-2 as a potential natural anti-osteoporotic agent for pharmacotherapy.

Abstract
Re-fracture risk is higher following osteoporotic fracture. However, there is no accurately reported rate of re-fracture incidence in southwest China. The purpose of this study was to describe the osteoporotic vertebral fracture (OVF) survival for re-fracture state and analyze the risk of re-fracture. This historical cohort study was conducted in four hospitals in southwest China. Patients aged ≥ 50 years (n = 586) with OVF who were supposed to receive anti-osteoporosis drugs after the fracture were included (2012-2017). Telephone follow-up and referring case files were used to estimate the survival for re-fracture and identify the determinants of re-fracture. A total of 555 patients completed the follow-up investigation. Overall, 285 patients experienced a re-fracture, and the longest follow-up investigation time was 72 months. The survival rates for re-fracture at 12 months, 24 months, 36 months, and 48 months were 82.0%, 71.5%, 61.7%, and 34.0%, respectively. The factors correlated with re-fracture hazard were advanced age [hazard ratio (HR) = 1.996], being female (HR = 1.342), smoking (HR = 1.435), history of hypertension (HR = 1.219) and diabetes (HR = 3.271), and persistence of taking anti-osteoporosis drugs after fracture [0-3 months, 4-6 months, 7-12 months, and more than 12 months (HR = 0.703)]. OVF patients with advanced age, who were female, smoked, had fracture with hypertension or diabetes, and who complied poorly with anti-osteoporosis drug treatment presented higher prevalence of re-fracture and low anti-osteoporosis adherence in southwest China. The management of anti-osteoporosis after fracture is necessary in this area.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Achyranthes bidentata Blume (AB) is a well-known traditional Chinese medicine for treating osteoporosis and bone fracture. In the current, researches on pharmacological mechanism of AB mostly focused on molecular pathways, knowledge about its metabolic signatures is largely unclear. This study aims to develop an integrative metabolomics and metallomic approach for deciphering the biochemical basis of anti-osteoporosis effects of raw and salt-processed AB. METHOD Gas chromatography-mass spectrometry (GC-MS) and inductively coupled plasma mass spectrometry (ICP-MS) were combined for metabolomic and metallomic profiling of rats serum, liver and kidney derived from the sham group, model group, E2, raw and salt-processed AB treated groups. Meanwhile, micro-CT and biomechanical analysis were carried out to ensure the success of the osteoporosis model and to validate the anti-osteoporosis effect of raw and salt-processed AB. Partial least squares discriminant analysis (PLS-DA) was employed to screen potential biomarkers and the MetaboAnalyst and KEGG PATHWAY Database were used to investigate the metabolic pathway. RESULTS Raw and salt-processed AB protected the rats against osteoporosis, as evidenced by the restoration of the alkaline phosphatase activity, osteocalcin concentration, urine calcium/creatinine ratio and urine phosphorus/creatinine ratio. The combination of PCA and PLS-DA revealed deviations in ninety-four differential biomarkers between raw AB treated group and model group. The identified biomarkers were primarily engaged in the metabolic pathways including galactose metabolism, urea cycle, arginine and proline metabolism, alanine metabolism, lactose degradation, ammonia recycling and glycine and serine metabolism. The levels of these biomarkers showed significant alterations and a tendency to be restored to normal values in raw and salt-processed AB treated osteoporosis rats. Of note, the levels of trace elements, such as Zn, Se, Mn, Cu and Fe, were elevated after raw and salt-processed AB treatment. Finally, a correlation network diagram was constructed to show the biomarkers perturbed by raw and salt-processed AB. CONCLUSION Our findings indicate that raw and salt-processed AB has positive effects on osteoporosis rats. Meanwhile, metabolomic and metallomic method coupled with metabolites enrichment analysis and pattern recognition serves as a useful tool for revealing the action mechanism of traditional Chinese medicine.

Abstract
Morinda officinalis is an important traditional tonic herbal medicine. In the present study, we found that crude polysaccharides extracted from M. officinalis, named MO90, could significantly increase the bone mineral density (BMD) of the whole femur, distal femur, and proximal femur in ovariectomized (OVX) rats. In addition, MO90 decreased the level of bone turnover markers and prevented the deterioration of trabecular microarchitecture. To investigate the fractions responsible for anti-osteoporosis activity, one novel inulin-type fructan, MOW90-1, was isolated from MOP90. Structural analysis indicated that MOW90-1 consists of a backbone of (2→1)-linked-β-D-Fruf, and is terminated with (1→)-linked-α-D-Glcp and (2→)-linked-β-D-Fruf. Furthermore, an in vitro anti-osteoporosis assay indicated that MOW90-1 promoted proliferation, differentiation, and mineralization of MC3T3-E1 cells by up-regulating the expression of runt-related transcription factor 2, osterix, osteopontin, and osteocalcin. In conclusion, our studies provide supporting evidence for future use of this novel M. officinalis fructan as a key nutrient of health products.

Abstract
Two Epimedium-derived isomeric flavonoids, CIT and IT, had the therapeutic effect in osteopenic rats. However, it is difficult to expound their activity differences in anti-osteoporosis. This paper contrasted their anti-osteoporosis activity from the perspective of their affinity to OPG/RANKL protein targets. Molecular docking indicated that both of CIT and IT could interact with the hydrophobic pockets of OPG/RANKL, while CIT was easier and more stable to combine with RANKL. On the contrary, compared with CIT, IT was more inclined to combine with OPG and stay away from combining with RANKL. Subsequently, whether the interaction between isomeric flavonoids and OPG/RANKL targets promoted or suppressed bone resorption was undefined and which was validated by zebrafish embryo and ovariectomized rats in this paper. Compared with IT, the staining area and cumulative optical density of zebrafish skeleton were significantly increased after the treatment of CIT (0.1 μM, p < 0.05). Furthermore, CIT mainly reflected a more significant role in upregulating OPG (p < 0.05), downregulating RANKL (p < 0.05), reducing serum AKP and TRACP level (p < 0.05), enhancing bone biomechanical properties (p < 0.05), increasing bone mineral density (p < 0.05) and improving trabecular bone microarchitecture (p < 0.05) in osteoporotic rats. In conclusion, the combination of isomeric flavonoids (CIT/IT) and OPG/RANKL targets attenuated the excitation effects of OPG or RANKL on RANKL. Because CIT was more firmly combined with RANKL than IT, CIT had stronger anti-osteoporosis effect by inhibiting bone resorption.

Abstract
Two new lignans, zanthoxyloside C (1) and zanthoxyloside D (2), together with nine known compounds comprising lignans (3-5), flavonoids (6-8), and phenolics (9-11), were isolated from the methanol extract of the stems of Zanthoxylum piperitum. All isolates were evaluated for their antioxidant and anti-osteoporotic activities using oxygen radical absorbance capacity (ORAC), cupric reducing antioxidant capacity (CUPRAC), and tartrate-resistant acid phosphatase (TRAP) assays. Compounds 7-10 showed peroxyl radical-scavenging capacities and 4, 6-7, and 9 showed reducing capacities. Moreover, compounds 3, 6-9, and 11 significantly suppressed TRAP activities. These results indicated that the stems of Z. piperitum could be an excellent source for natural antioxidant and anti-osteoporosis.

Abstract
N16, a nacreous protein isolated from Pinctada martensii, is related to nacreous layer formation. Our previous study indicated that N16 showed dual regulatory effects by inducing osteoblast biomineralization as well as inhibiting osteoclast formation. In order to obtain large quantity of N16 for animal experiment and clinical trial, a fermentation and preparative purification method was established. The N16 cDNA was cloned to a BL21(DE3)plysE-pET32a vector and grown in a 20 L fermenter. The medium, temperature, pH and dissolved oxygen (DO) were optimized. N16 was expressed in inclusion bodies. It was denatured and refolded in 8 M urea buffer and purified to 97% purity by passing through a gel filtration column. The glucocorticoid induced osteoporosis (GIO) rat model was used to investigate the anti-osteoporosis activity of N16 in vivo. Results showed that the decrease of the bone mineral density (BMD) and the ultimate load was significantly relieved after N16 treatment. N16 displayed dual regulatory effects by promoting osteogenesis as well as inhibiting bone resorption in vivo. Our work will contribute to further clinical studies on N16 for osteoporosis treatment.

Abstract
Osteoporosis is characterized by an increasing osseous fragility and fracture resulting from the low mass and deteriorated microarchitecture in the bone tissue. The hormone replacement therapy and alendronate were frequently used to treat osteoporosis as the primary therapeutic strategy, but their adverse effects have severely limited their extensive clinical application, therefore, it is urgent to develop alternative or complementary therapeutic agents for anti-osteoporosis. Interestingly, with more people focusing on the complementary and alternative medicine, traditional Chinese herbs and formulas are being gradually recognized as safe and effective agents in the treatment of osteoporosis. In particular, a notable trend is that increasing studies are making efforts to clarify the anti-osteoporotic effects and mechanism of the tonifying kidney-yin herbs and formulas, a category of agents identified as effective therapy. Therefore, the purpose of this study is to comprehensively review the tonifying kidney-yin herbs and formulas that have been reported in the treatment of osteoporosis as well as how the agents play their roles in detail. This current study not only will advance our understanding of the actions of tonifying kidney-yin herbs and formulas, but also provide new evidence for the clinic use of the tonifying kidney-yin herbs and formulas in the treatment of osteoporosis.

Abstract
Icariin has a significant anti-osteoporotic activity, but its clinical application is limited due to a poor oral bioavailability especially under pathological conditions like osteoporosis. Based on the intestinal absorption and metabolism characteristics of icariin in the osteoporosis rats, a kind of simple enteric capsules containing icariin and snailase was designed to overcome this issue in this study. Snailase was secleted as the most efficient exogenous hydrolase of icariin and the related hydrolysis reaction parameters were optimized in the artificial intestinal liquid. Moreover, the hydrolysates of icariin were proved more effective in promoting the rat calvarial osteoblast proliferation than icariin by the MTT assay. Therefore, snailase and icariin were packed into the enteric-coated capsules at an appropriate mass ratio of 1:1 to prepare the icariin loaded enteric-coated capsules (IECs), and then the in vitro release and in vivo pharmacokinetic behavior of IECs was evaluated. Icariin was almost completely hydrolyzed within 4h and approximately 89% of the total flavonoid had been released from IECs at 0.75h in the release medium, which met the requirement of the Chinese Pharmacopoeia on enteric preparations and the Weibull function model. The pharmacokinetic data showed IECs could significantly improved the integrated oral bioavailability of icariin by 50% compared to the IP (icariin without the snailase) in the ovariectomized rats, but no obvious difference was observed in the sham rats. The aforementioned results suggested that such a strategy of icariin combined with the snailase held a great potential in promoting the intestinal hydrolysis and absorption of icariin in the osteoporosis status, providing new research ideas for the active ingredients of traditional Chinese medicine with similar properties.

Abstract
Osteoporosis is characterized by a reduction in bone mass and bone mineral density, which weakens the bone. Due to the side effects associated with drugs that are currently used to treat this disease, an increasing number of studies have focused on the research of effective ingredients derived from natural products. In particular, polysaccharides extracted from Chinese herbal medicines have received increasing attention. In this study, we isolated a homogeneous polysaccharide (COP90-1) from the dried rhizomes of Curculigo orchioides, a famous traditional Chinese medicine that is widely used in China, and determined its structure using the combined methods of chemical and spectral analyses. In addition, its effects on the proliferation and differentiation of primary mouse osteoblasts were assessed. The results showed that COP90-1 can effectively promote the proliferation and differentiation of primary osteoblasts in vitro. Additional studies are warranted to study the effects of this compound in vivo.

Abstract
The metabolism of eldecalcitol (ED-71), a 2β-hydroxypropoxylated analog of the active form of vitamin D3 was investigated by using in vitro systems. ED-71 was metabolized to 1α,2β,25-trihydroxyvitamin D3 (1α,2β,25(OH)3D3) in human small intestine and liver microsomes. To identify the enzymes involved in this metabolism, we examined NADPH-dependent metabolism by recombinant P450 isoforms belonging to the CYP1, 2, and 3 families, and revealed that CYP3A4 had the activity. However, the CYP3A4 -specific inhibitor, ketoconazole, decreased the activity in human liver microsomes by only 36%, suggesting that other enzymes could be involved in ED-71 metabolism. Because metabolism was dramatically inhibited by cyanide, we assumed that sterol C4-methyl oxidase like gene product (SC4MOL) might contribute to the metabolism of ED-71. It is noted that SC4MOL is physiologically essential for cholesterol synthesis. Recombinant human SC4MOL expressed in COS7, Saccharomyces cerevisiae, or Escherichia coli cells converted ED-71 to 1α,2β,25(OH)3D3. Furthermore, we evaluated the metabolism of ED-71 by recombinant CYP24A1, which plays an important role in the metabolism of the active form of vitamin D3 (1α,25(OH)2D3) and its analogs. The kcat/Km value for 24- or 23-hydroxylation of ED-71 was only 3% of that for 1α,25(OH)2D3, indicating that ED-71 was resistant to CYP24A1-dependent catabolism. Among the three enzymes catalyzing ED-71, SC4MOL appears to be most important in the metabolism of ED-71. To the best of our knowledge, this is the first study showing that SC4MOL can function as a drug-metabolizing enzyme. The yeast and E. coli expression systems for SC4MOL could be useful for structure-function analyses of SC4MOL.
