Obesity has become a critical public health challenge worldwide. Prioritizing prevention and tackling root causes—rather than merely managing symptoms—is critical to curbing this pandemic. Strategies that activate and expand brown adipose tissue and beige adipose tissue increase energy expenditure in animal models and offer therapeutic promise to treat obesity. Sanhuang Xiexin Decoction (SHX) is a well-known traditional Chinese medicine that possesses several beneficial effects, including anti-inflammatory and anti-atherosclerotic properties. This study aims to investigate whether SHX can alleviate obesity by promoting the browning process in adipose tissue. UPLC MS/MS was used to detect the constituents of SHX extraction, as well as the absorbed components of SHX in rat plasma. In vivo, C57BL/6 J mice were fed with 60

Ginkgo biloba Extract( GBE50) Dispersible Tablets is a new standardized prescription,which is widely used in the treatment of ischemic cardiovascular and cerebrovascular diseases. However,there are still many problems in its clinical application.Rational and safe use of GBE50 Dispersible Tablets is pivotal to the medication safety and clinical prognosis of patients. This consensus has been jointly formulated by clinical experts of traditional Chinese medicine and western medicine in cardiovascular and cerebrovascular diseases and followed the Manual for the Clinical Experts Consensus of Chinese Patent Medicine published by the China Association of Chinese Medicine. The present study identified clinical problems based on clinical investigation,searched the research papers according to PICO clinical problems,carried out evidence evaluation,classification,and recommendation by GRADE system,and reached the expert consensus with nominal group technique. The consensus combines evidence with expert experience. Sufficient evidence of clinical problems corresponds to " recommendations",while insufficient evidence to " suggestions". Safety issues of GBE50 Dispersible Tablets,such as indications,usage and dosage,and medication for special populations,are defined to improve clinical efficacy,promote rational medication,and reduce drug risks. This consensus needs to be revised based on emerging clinical issues and evidencebased updates in practical applications in the future.
"异病同治"是指不同的疾病,在其发展过程中,由于出现了相同的病机,而采用同一方法治疗的法则.恒古骨伤愈合剂由三七、红花、人参、黄芪、杜仲、鳖甲、钻地风、洋金花、陈皮组成,是现代中医临床"异病同治"的一种代表性药物.多项临床研究表明,恒古骨伤愈合剂治疗骨折、股骨头坏死、骨关节炎、腰椎间盘突出症等均取得了较好疗效.虽然现代医学认为这4种骨伤疾病的发病机制不同,但中医学认为其病因病机基本相同,均为瘀血、风湿痹阻、肝肾气血亏虚、经脉筋骨失养所致.恒古骨伤愈合剂针对这4种骨伤疾病"瘀血阻络、筋骨失养"的共同病机遣方用药,具有活血化瘀、散结生新、滋补肝肾、荣筋养骨的功效,充分体现了中医"圆机活法""异病同治""辨证用药"的理法特色.同时恒古骨伤愈合剂的现代药理机制研究及临床应用研究,也为其"一药多用"和"异病同治"提供了现代科学依据.本文从中医对4种骨伤疾病发病机理的认识、恒古骨伤愈合剂的方解及其治疗4种骨伤疾病的药理机制和临床运用4个方面,探讨并揭示了恒古骨伤愈合剂能"一药多用"和"异病同治"的科学内涵,为指导临床合理用药提供了借鉴.
Background Adipose tissue (e.g. white, brown and brite) plays a critical role in modulating energy metabolism. Activating brown adipose tissue (BAT) and inducing browning in white adipose tissue (WAT) has been proposed to be a potential molecular target for obesity treatment. Emodin is a natural anthraquinone derivative that exhibits variety of pharmacologic effects including lowering lipids and regulating glucose utilization. However, the underlying mechanism of action is still unclear. In the present study, we investigated whether emodin could alleviate obesity via promoting browning process in adipose tissue. Methods C57BL/6J mice were fed with high fat diet to induce obesity. Emodin at the doses of 40 and 80 mg/kg were orally given to obesity mice for consecutive 6 weeks. Parameters including fasting blood glucose, oral glucose tolerance, blood lipids, and the ratios of subcutaneous white adipose tissue (scWAT) or BAT mass to body weight, and morphology of adipose tissue were observed. Besides, the protein expression of uncoupling protein 1 (UCP1) and prohibitin in BAT and scWAT was determined by immunohistochemistry method. Relative mRNA expression of Cd137, transmembrane protein 26 (Tmem26) and Tbx1 in scWAT was analyzed using qRT-PCR. And the protein expression of UCP1, CD36, fatty acid transporter 4 (FATP4), peroxisome proliferator-activated receptor alpha (PPARα) and prohibitin of scWAT and BAT were analyzed using western blotting. In addition, ultra-high-performance liquid chromatography with electrospray ionization tandem mass spectrometry was utilized to detect the small lipid metabolites of scWAT and BAT. Results Emodin decreased the body weight and food intake in HFD-induced obesity mice, and it also improved the glucose tolerance and reduced the blood lipids. Emodin treatment induced beiging of WAT, and more multilocular lipid droplets were found in scWAT. Also, emodin significantly increased markers of beige adipocytes, e.g. Cd137, Tmem26 and Tbx1 mRNA in scWAT, and UCP1, CD36, FATP4, PPARα and prohibitin protein expression in scWAT and BAT. Furthermore, emodin perturbed the lipidomic profiles in scWAT and BAT of obese mice. Emodin increased total ceramides (Cers), lysophosphatidylcholines (LPCs), lyso-phosphatidylcholines oxygen (LPCs-O), and phosphatidylethanolamines oxygen (PEs-O) species concentration in scWAT. Specifically, emodin significantly up-regulated levels of Cer (34:1), LPC (18:2), LPC-(O-20:2), PC (O-40:7), PE (O-36:3), PE (O-38:6), PE (O-40:6), and sphingolipid (41:0) [SM (41:0)], and down-regulated PC (O-38:0), PE (O-40:4), PE (O-40:5) in scWAT of obesity mice. In terms of lipid matabolites of BAT, the emodin remarkably increased the total PCs levels, which was driven by significant increase of PC (30:0), PC (32:1), PC (32:2), PC (33:4) and PC (38:0) species. In addition, it also increased species of LPCs, e.g. LPC (20:0), LPC (20:1), LPC (22:0), LPC (22:1), LPC (24:0), and LPC (24:1). Especially, emodin treatment could reverse the ratio of PC/PE in HFD-induced obese mice. Conclusions These results indicated that emodin could ameliorate adiposity and improve metabolic disorders in obese mice. Also, emodin could promote browning in scWAT and activate the BAT activities. In addition, emodin treatment-induced changes to the scWAT and BAT lipidome were highly specific to certain molecular lipid species, indicating that changes in tissue lipid content reflects selective remodeling in scWAT and BAT of both glycerophospholipids and sphingolipids in response to emodin treatment.

目前,全球大约22亿人超重,约占全球总人口的1/3,其中约7.12亿人(占全球总人口的10%)是肥胖人群[1].肥胖主要是由于机体长期处于能量储存大于能量消耗的一种状态下所造成的体内白色脂肪组织与棕色脂肪失衡.白色脂肪组织的功能主要是将机体中过剩的能量以中性脂肪的形式贮存起来,以供机体需求时利用.棕色脂肪组织的主要功能是促进机体产热.近年来,随着对肥胖和相关代谢疾病的深入研究,发现棕色脂肪组织具有提高机体能量代谢的特殊生理功能,在维持体温和调控能量平衡方面发挥着重要的作用.棕色脂肪组织中含有一种位于线粒体内膜上的载体蛋白,即解偶联蛋白-1(Uncoupling protein 1,UCP-1).UCP-1可以将H+从线粒体内膜渗漏到线粒体基质中,阻止ADP磷酸化形成ATP,将能量以热能的形式散失.

Based on the autonomic learning content and teaching methods of pharmacology of traditional Chinese medicine, this paper discusses the design and implementation strategies of pluralistic evaluation system including learning in the classroom, expands the learning out of the classroom, experimental operation and final examination, which emphasizes the combination of process evaluation and the participation of teachers and students. It is beneficial to stimulate students'self-learning motivation and improve their self-learning ability and learning effect.
Background: Diabetic cardiomyopathy (DCM) is considered to be a distinct clinical entity independent of concomitant macro- and microvascular disorders, which is initiated partly by disturbances in energy substrates. This study was to observe the dynamic modulations of berberine in DCM rats and explore the changes of lipidomic profiles of myocardial tissue. Methods: Sprague-Dawley (SD) rats were fed high-sucrose and high-fat diet (HSHFD) for totally 22 weeks and intraperitoneally (i.p.) injected with 30 mg/kg of streptozotocin (STZ) at the fifth week to induce DCM. Seventy-two hours after STZ injection, the rats were orally given with berberine at 10, 30 mg/kg and metformin at 200 mg/kg, respectively. Dynamic changes of cardiac function, heart mass ratios and blood lipids were observed at f 4, 10, 16, and 22, respectively. Furthermore, lipid metabolites in myocardial tissue at week 16 were profiled by the ultra-high-performance liquid chromatography coupled to a quadruple time of flight mass spectrometer (UPLC/Q-TOF/MS) approach. Results: Berberine could protect against cardiac diastolic and systolic dysfunctions, as well as cardiac hypertrophy, and the most effective duration is with 16-week of administration. Meanwhile, 17 potential biomarkers of phosphatidylcholines (PCs), phosphatidylethanolamines (PEs) and sphingolipids (SMs) of DCM induced by HSFD/STZ were identified. The perturbations of lipidomic profiles could be partly reversed with berberine intervention, i.e., PC (16:0/20:4), PC (18:2/0:0), PC (18:0/18:2), PC (18:0/22:5), PC (20:4/0:0), PC (20:4/18:0), PC (20:4/18:1), PC (20:4/20:2), PE (18:2/0:0), and SM (d18:0/16:0). Conclusions: These results indicated a close relationship between PCs, PEs and SMs and cardiac damage mechanisms during development of DCM. The therapeutic effects of berberine on DCM are partly caused by interferences with PCs, PEs, and SMs metabolisms.
