Abstract
Ligustroflavone is one major compound contained in active fraction from Fructus Ligustri Lucidi (the fruit of Ligustrum lucidum), which could regulate parathyroid hormone (PTH) levels and improve calcium balance by acting on calcium-sensing receptors (CaSR). This study aimed to explore the potency of ligustroflavone as a CaSR antagonist and its protective effects against diabetic osteoporosis in mice. LF interacted well with the allosteric site of CaSR shown by molecular docking analysis, increased PTH release of primary parathyroid gland cells and suppressed extracellular calcium influx in HEK-293 cells. The serum level of PTH attained peak value at 2 h and maintained high during the period of 1 h and 3 h than that before treatment in mice after a single dose of LF. Treatment of diabetic mice with LF inhibited the decrease in calcium level of serum and bone and the enhancement in urinary calcium excretion as well as elevated circulating PTH levels. Trabecular bone mineral density and micro-architecture were markedly improved in diabetic mice upon to LF treatment for 8 weeks. LF reduced CaSR mRNA and protein expression in the kidneys of diabetic mice. Taken together, ligustroflavone could transiently increase PTH level and regulate calcium metabolism as well as prevent osteoporosis in diabetic mice, suggesting that ligustroflavone might be an effective antagonist on CaSR.

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.

Fructus Ligustri Lucidi in Osteoporosis: A Review of its Pharmacology, Phytochemistry, Pharmacokinetics and Safety. Molecules 2017; 22:molecules22091469. [PMID: 28872612 PMCID: PMC6151717 DOI: 10.3390/molecules22091469] [Citation(s) in RCA: 49] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2017] [Revised: 08/30/2017] [Accepted: 09/01/2017] [Indexed: 12/15/2022] Open
Abstract
Background: Fructus Ligustri Lucidi (FLL) has now attracted increasing attention as an alternative medicine in the prevention and treatment of osteoporosis. This study aimed to provide a general review of traditional interpretation of the actions of FLL in osteoporosis, main phytochemical constituents, pharmacokinetics, pharmacology in bone improving effect, and safety. Materials and Methods: Several databases, including PubMed, China National Knowledge Infrastructure, National Science and Technology Library, China Science and Technology Journal Database, and Web of Science were consulted to locate publications pertaining to FLL. The initial inquiry was conducted for the presence of the following keywords combinations in the abstracts: Fructus Ligustri Lucidi, osteoporosis, phytochemistry, pharmacokinetics, pharmacology, osteoblasts, osteoclasts, salidroside. About 150 research papers and reviews were consulted. Results: FLL is assumed to exhibit anti-osteoporotic effects by improving liver and kidney deficiencies and reducing lower back soreness in Traditional Chinese Medicine (TCM). The data from animal and cell experiments demonstrate that FLL is able to improve bone metabolism and bone quality in ovariectomized, growing, aged and diabetic rats through the regulation of PTH/FGF-23/1,25-(OH)2D3/CaSR, Nox4/ROS/NF-κB, and OPG/RANKL/cathepsin K signaling pathways. More than 100 individual compounds have been isolated from this plant. Oleanolic acid, ursolic acid, salidroside, and nuzhenide have been reported to exhibit the anti-osteoporosis effect. The pharmacokinetics data reveals that salidroside is one of the active constituents, and that tyrosol is hard to detect under physiological conditions. Acute and subacute toxicity studies show that FLL is well tolerated and presents no safety concerns. Conclusions: FLL provides a new option for the prevention and treatment of osteoporosis, which attracts rising interests in identifying potential anti-osteoporotic compounds and fractions from this plant. Further scientific evidences are expected from well-designed clinical trials on its bone protective effects and safety.

Abstract
The present study aimed to investigate the mechanism of hepatoprotective effect of Erzhi Pill (EZP) on the liver injury via observing TSC/mTOR signaling pathway activation. The experimental liver injury was induced by 2-acetylaminofluorene (2-AAF) treatment combined with partial hepatectomy (PH). EZP treated 2-AAF/PH-induced liver injury by the therapeutic and prophylactic administration. After the administration of EZP, the activities of aspartic transaminase (AST), alanine aminotransferase (ALT), alkaline phosphatase (AKP), and gamma-glutamyl transpeptidase (γ-GT) were decreased, followed by the decreased levels of hepatocyte apoptosis and caspase-3 expression. However, the secretion of albumin, liver weight, and index of liver weight were elevated. Microscopic examination showed that EZP restored pathological liver injury. Meanwhile, Rheb and mammalian target of rapamycin (mTOR) activation were suppressed, and tuberous sclerosis complex (TSC) expression was elevated in liver tissues induced by 2-AAF/PHx and accompanied with lower-expression of Bax, Notch1, p70S6K, and 4E-EIF and upregulated levels of Bcl-2 and Cyclin D. Hepatoprotective effect of EZP was possibly realized via inhibiting TSC/mTOR signaling pathway to suppress excessive apoptosis of hepatocyte.

Abstract
OBJECTIVE To assess the ability of whole body vibration (WBV) with the kidney-tonifying herbal Fufang (Bushen Zhuanggu Granules, BZG) to prevent osteoporosis in ovariectomized rats. METHODS Fifty 6-month-old female Sprague Dawley rats were divided into five groups: sham-operated (SHAM), ovariectomized (OVX), OVX with WBV (OVX + WBV), OVX with BZG (OVX + BZG), OVX with both WBV and BZG (OVX + WBV + BZG). The SHAM group received normal saline. After 12 weeks of treatment, the rats were killed, their serum concentrations of osteopontin (OPN), receptor activator of nuclear factor kappa-B ligand RANKL and bone turnover markers assayed and bone mineral density (BMD), histomorphometry and bone strength evaluated. RESULTS Concentrations of OPN were significantly lower in the SHAM, OVX + WBV and OVX + WBV + BZG groups at 12 weeks, whereas concentrations of RANKL had decreased significantly in the SHAM, OVX + WBV, OVX + BZG and OVX + WBV + BZG groups. In the OVX + WBV, OVX + BZG and OVX + WBV + BZG groups the amount of bone turnover had been significantly antagonized. Compared with OVX group, BMD, % trabecular area (Tb.Ar), number of trabeculae (Tb.N) and assessed biomechanical variables were higher in OVX+WBV group, whereas and BMD, %Tb.Ar, Tb.N, maximal load and yield load were higher in the OVX + BZG group. All tested indices were significantly lower in the OVX + WBV and OVX + BZG groups than in the OVX + WBV + BZG group. CONCLUSION Either WBV or BZG alone prevents OVX-induced bone loss. However, BZG enhances the effect of WBV by further enhancing BMD, bone architecture and strength.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Fructus Ligustri Lucidi (FLL), the fruit of Ligustrum lucidum Ait, is a commonly prescribed herb to nourish the endocrine and renal systems and to strengthen the bones in Traditional Chinese Medicine. This study was aimed to determine the effects of water fraction of FLL ethanol extract (WF-EE) on urinary calcium excretion and trabecular bone properties in type 1 diabetic mice. MATERIALS AND METHODS The DBA/2J mice with type 1 diabetes induced by streptozotocin injection were orally administered with WF-EE. After 6 weeks of treatment, the level of biomarkers, including serum calcium, parathyroid hormone (PTH), and fibroblast growth factor-23 (FGF-23) and urine calcium, was measured. Micro-CT was performed to detect trabecular bone properties of the proximal tibial metaphysis. The expression of active calcium transporting proteins in kidney and duodenum was determined by RT-PCR, immunoblotting and immunostaining. RESULTS Type 1 diabetes induced hypercalciuria and trabecular bone deterioration. The WF-EE could significantly inhibit hypercalciuria and ameliorate the micro-structure of trabecular bone as well as increase serum PTH and FGF-23 levels in type 1 diabetic mice. The gene expressions of active calcium transporting proteins in duodenum were up-regulated, and the gene and protein expressions of calcium-sensing receptor (CaSR) in kidney were dramatically down-regulated in diabetic mice in response to the treatment with WF-EE. CONCLUSIONS The present study demonstrated the protective effects of the water fraction of Fructus Ligustri Lucidi ethanol extract against hypercalciuria and trabecular bone deterioration in experimentally type 1 diabetic mice, and the underlying mechanism may be attributed to its regulations on duodenal calcium transporting proteins and renal CaSR.
