ABSTRACT
Osteoporosis （OP） is a systemic metabolic disease that affects the health of middle-aged and elderly people by crosslinking multiple signaling pathways. With the increasing aging of the population， the incidence of OP is also increasing year by year. Because of a series of problems such as high incidence， difficulty in treatment， and poor prognosis， it has been widely studied and reported by scholars in China and abroad. At present， the drugs used by western medicine are mainly divided into two categories： Bone resorption inhibitors and bone formation promoters. Although the efficacy is reliable， there are still deficiencies such as poor dependence of patients on the drug， uncontrollable side effects， and high costs. However， in recent years， with the continuous deepening and innovation of traditional Chinese medicine （TCM） research， the treatment of OP by TCM has been widely recognized in clinical practice. Many scholars have found that the mechanism of TCM in the treatment of OP includes the widespread involvement of mitogen-activated protein kinase （MAPK） signaling pathway， which mainly promotes the differentiation of bone marrow mesenchymal stem cells （BMSCs） to osteoblasts （OB）， inhibits the differentiation of osteoclasts （OC）， and improves the expression of osteogenesis-related factors alkaline phosphatase （ALP）， Runt-associated transcription factor 2 （Runx2）， type Ⅰ collagen （ColⅠ） to treat OP. Although the current research on the TCM treatment of OP through the MAPK pathway is deepening， there are still certain deficiencies in the study of its molecular mechanism. Therefore， this paper reviewed the relationship between the MAPK signaling pathway and key target protein factors and OP to clarify the important role of the MAPK signaling pathway in OP. At the same time， the targeted regulation of MAPK signaling pathways by TCM to treat OP was systematically summarized in order to provide a scientific basis for the further accurate treatment of OP in TCM.
ABSTRACT
With the gradual aggravation of aging in China， the prevalence of osteoporosis is increasing year by year. Osteoporosis has become a major public health problem threatening the health of middle-aged and elderly people， especially middle-aged and elderly women. There are many predisposing factors and complex pathogenesis of osteoporosis. The interpretation of osteoporosis has been the focus of clinical research in recent years. How to prevent and treat osteoporosis more effectively has also become a major problem faced by researchers. In recent years， the balance and homeostasis of calcium and phosphorus regulated by intestinal absorption， renal excretion and bone have become one of the hot topics， and the balance and homeostasis of calcium and phosphorus in vivo are the key to normal bone homeostasis. At the same time， as a complex microbial community living in the gastrointestinal tract， intestinal flora can produce a variety of regulators affecting metabolism. It has been widely confirmed that it acts on the body indirectly or directly， in multiple ways and targets to prevent and treat osteoporosis. Therefore， further exploring the role and mechanism of intestine kidney bone axis in osteoporosis plays a far-reaching significance for the prevention and treatment of osteoporosis. In recent years， scholars have made a lot of exploration on the prevention and treatment of osteoporosis with traditional Chinese medicine （TCM）， and found that TCM can intervene the expression of intestinal flora and play the effect of prevention and treatment of osteoporosis. Based on the "intestine kidney bone axis"， this paper briefly discusses the integrated traditional Chinese and western medicine of kidney and osteoporosis， intestine and osteoporosis， intestine kidney axis， the treatment of kidney from intestine， intestine and osteoporosis， and the application of TCM in regulating intestinal flora in osteoporosis， in order to provide new ideas for the prevention and treatment of osteoporosis.

ABSTRACT
Osteosarcoma (OS) is the most common primary malignant bone tumor in clinic. It has high mortality and disability rate. Effective neoadjuvant chemotherapy combined with limb salvage surgery can improve the 5-year survival rate of OS patients. Drug resistance or low sensitivity of tumor cells is the most common cause of postoperative local recurrence and metastasis. Therefore, the sensitivity of OS cells to chemotherapy drugs is of great value to the prognosis of the patients. In recent years, traditional Chinese medicine has been widely used because of high efficiency and low toxicity. A large number of studies have confirmed that part of traditional Chinese medicine can reverse the chemotherapy resistance of OS cells by regulating the ABC transmembrane transport protein system. This article gives an overview of its related mechanisms and latest developments.
ABSTRACT
BACKGROUND:In recent years, in-depth studies that single Chinese herbs or extracts, compound traditional Chinese medicine and medicated serum are used to regulate the directional differentiation of bone marrow mesenchymal stem cels into myofibroblasts, chondrocytes, osteoblasts, myocardial cels and nerve cels, which have become a highlight in the tissue engineering research. OBJECTIVE:To review the latest progress in the directional differentiation of bone marrow mesenchymal stem cels induced by Chinese herbs or their extracts. METHODS:The first author searched the CNKI, Wanfang and PubMed databases using the keywords of “Chinese herb, directional differentiation, mesenchymal stem cels” in Chinese and English, respectively, to retrieve relevant articles published from January 2010 to January 2016. Repetitive articles or those with no originality were eliminated. Totaly 99 articles were searched initialy, and then 43 articles were included in result analysis. RESULTS AND CONCLUSION:As the strongest seed cels in the bone differentiation system, bone marrow mesenchymal stem cels have a wide range of directional differentiation potential, and highlight the important value in combination with Chinese herbs for clinical treatment of various refractory diseases, especialy for treatment of metabolic bone diseases, bone defects, nonunion and delayed union, which is not only conducive to in-depth, multi-angle studies on effects and mechanisms of Chinese herbs, but also to clinical treatment of various refractory diseases using bone marrow mesenchymal stem cels.
