RESUMO
The pathogenesis of metabolic syndrome （MS） includes insulin resistance （IR）， central obesity， chronic low-grade inflammation， oxidative stress， endoplasmic reticulum stress， elevated free fatty acid levels， intestinal flora imbalance， renin angiotensin system abnormality， and autophagy activity deficiency， etc. Most researchers believe that IR plays a central role in the pathogenesis of MS， and abdominal obesity is an important initial factor of MS. According to the incidence and clinical characteristics， MS is classified as "obesity" "pidan" " abdominal fullness " and other diseases. It is said that the pathogenesis of MS is related to the deficiency of spleen and kidney， the formation of phlegm， turbidity， blood stasis and other pathological products， which damage the body's functions of qi， blood， yin and yang. Traditional Chinese medicine （TCM） has unique advantages in treating MS based on the holistic view and syndrome differentiation concept. It has multi-level， multi-target and multi-channel treatment characteristics. It can intervene insulin signal transduction， regulate adipocyte factor secretion level， relieve oxidative stress and endoplasmic reticulum stress response， regulate intestinal flora and renin angiotensin system， reduce free fatty acid level and regulation Autophagy and other ways to improve chronic low-grade inflammation and IR status， and then comprehensive prevention and treatment of MS and its complications. However， the following problems still exist：lack of high-quality randomized controlled clinical research and large sample real-world research， clinical unified diagnosis and treatment standard has not yet formed， lack of genetic animal model in basic research， relatively single signal pathway and target of experimental research， and difficulty in timely formation of clinical transformation of scientific research achievements. Therefore， we should make full use of modern scientific and technological means to carry out systematic and standardized multicenter， large sample， high-quality randomized controlled trials or real-world research， we should prepare perfect animal models， focus on the crosstalk relationship between multiple related cell signaling pathways， and actively explore the potential relationship between signaling pathways and prescription compatibility， so as to actively promote basic scientific research achievements Clinical practice may be the key research direction in the prevention and treatment of MS in TCM.
RESUMO
Metabolic syndrome (MS) is a pathological condition characterized by central obesity, insulin resistance, hypertension, and hyperlipidemia. With the increase of poor dietary habits and lifestyles in modern society, especially the poor living habits of sedentariness and less movement, the prevalence of MS has increased year by year. According to relevant data, the number of MS patients worldwide will reach about 2.568 billion by 2040, which will seriously endanger human life and health. Huanglian Wendantang, as a famous traditional Chinese medicine prescription for clearing away heat and drying dampness, regulating Qi and resolving phlegm, and benefiting the stomach and gall, has been proved to have significant pharmacological effects in lowering blood fat, reducing blood sugar and resisting inflammation by modern pharmacological studies, and widely used in the treatment of metabolic diseases, cardiovascular diseases and other systemic diseases. In recent years, a large number of studies have proved that Huanglian Wendantang has a significant effect on MS. In terms of clinical efficacy, it could significantly improve the pathological state of obesity, dyslipidemia, abnormal glucose metabolism and hypertension in MS patients. Meanwhile, it could also interfere with the inflammatory state, prethrombotic state, abnormal vascular regulation and other potential risk factors in the body, with a high safety and fewer side effects. In terms of experimental study, it could enhance the insulin sensitivity, and improve the insulin resistance of MS animal models and cell models through interventions in insulin signal transduction, inflammatory response, and antioxidant stress. By retrieving PubMed, CNKI, Weipu, Wanfang and other databases, the author summarized the study reports of Huanglian Wendantang on MS in recent years in three aspects: theoretical study, clinical efficacy study and experimental mechanism study, in the expectation of provide some scientific references for in-depth study of the mechanism of Huanglian Wendantang in treating MS and the development and clinical promotion of the prescription.
RESUMO
Objective To examine the induction effects of bone marrow mesenchymal stem cells(BMSCs) transfected with bone morphogenetic protein 7 (BMP7) gene differentiating into chondrocytes. Methods We observed the phenotype of cells which were stained with alcian blue and HE climbing to the six pore plate with invert microscope. The glycosaminoglycan (GAG) value in culture medium was detected in control group,BMP7 transfect and culture medium induced groups after 7,14 and 21 days using standard curve method. Standard curve was described using galacturonic-acid as reference substance. The content of collagen Ⅱ was detected by ELISA method. Results HE and Alcian blue staining showed that BMP7 gene transfection group and the group induced by fluid possess the characteristics of chondrocyte. BMP7 induced BMSCs differentiation to chondrocyte which secrete specific protein called collagen Ⅱ and GAG. Content of GAG were (17.1±3.4),(39.5±5.4),(40.8±6.1)mg/L in control group,BMP7 gene transfected group and induced group,collagen Ⅱ were (89.7±14.3),(152.8±14.5),(155.5± 19.3)μg/L in these three groups separately. Comparing with control group,GAG and collagen Ⅱ of BMP7 gene transfected group and culture medium induced group increased obviously(all P < 0.05),but there was no significant difference between BMP7 gene transfeeted group and culture medium induced group (P > 0.05). Conclusion This active protein induces BMSCs differentiating into chondrocyte,in a level similar to that of inducing medium.
