Chemical components and mechanism of Jiuwei Huaban pill in treating psoriasis

Objective:To systematically study the key active ingredients of Jiuwei Huaban pill in the treatment of psoriasis and explore its mechanism of action.Methods:The chemical components of Jiuwei Huaban pill were systematically identified by UPLC-QTOF/MSE,and network pharmacology method was used to study the main pharmacodynamic substances of Jiuwei Huaban pill and discuss the mechanism of action.Molecular docking technology was used to verify the binding activity of key components and target proteins.Results:A total of 75 components of Jiuwei Huaban pill were identified,35 of which were key components for psoriasis treatment,including luteolin,baicalin,baicalin,paeoniflorin and geniposide.Enrichment analysis of 30 core target pathways showed that Jiuwei Huaban pill played its role in the treatment of psoriasis from the IL-17 signaling pathway,TNF signaling pathway,PI3K-Akt signaling pathway,Th17 signaling pathway,and MAPK signaling pathway.The key active components in Jiuwei Huaban pill and targets with the highest DGREE value in the"component target disease"network have strong binding activity.Conclusion:The active ingredients and mechanism of action of Jiuwei Huaban pill in the treatment of psoriasis were preliminarily clarified,which provids reference for quality control.

The Safety and Tolerance of Herbal Anti-Angina Drug Compound Danshen Droplet Pill in Healthy Volunteers

Background: Compound Salvia Pellet (T89), consisting of Danshen (salvia miltiorrhiza), Sanqi (panax notoginseng), and Borneol (Cinnamomum camphora), has been used worldwide for 14 years for chronic angina treatment. Purpose: A dose escalation study to determine the maximum tolerance dose (MTD) in Chinese population to support a proposed dose regimen change. Methods: Forty-six participants (age 18 to 45 yrs, male to female ratio = 1:1) were divided into a series of 6 patients cohorts, and sequentially assigned into one of the escalating dose groups, starting from 540 mg, the clinical doses, until 4 out of 6 subjects experience clinical Adverse Events (AEs) or when the pre-defined 3510 mg dose level is reached and completed. All doses were given orally as a single dose 2 hours after breakfast. Adverse events, vital signs, 12-lead ECG, clinical and laboratory parameters and medical evaluation were conducted as outcome measures. Results: Study completed at the highest pre-defined dose level of 3510 mg dose as never had 4/6 of subject experience AEs in any dose levels studied. All participants completed the study and data were included in the safety analysis. The only moderate AE observation (muscle damage) was observed at 2970 mg dose and was recovered without any medical treatment, and all other AEs (ECG, dizziness, muscle damage) were mild and may (5 cases) or may not (9 cases) be related to testing drug and were all self-resolved within 30 min after dose. Conclusion: Given as single oral dose, Compound Salvia Pellet is safe and well-tolerated up to the 3510 mg studied. The MTD value of Compound Salvia Pellet is unknown from this trial and must be higher than 3510 mg, 13 times higher than its current clinical dose.

Compound Danshen Dripping Pill inhibits hypercholesterolemia/atherosclerosis-induced heart failure in ApoE and LDLR dual deficient mice via multiple mechanisms

Heart failure is the leading cause of death worldwide.Compound Danshen Dripping Pill(CDDP)or CDDP combined with simvastatin has been widely used to treat patients with myocardial infarction and other cardiovascular diseases in China.However,the effect of CDDP on hypercholesterolemia/atherosclerosis-induced heart failure is unknown.We constructed a new model of heart failure induced by hypercholesterolemia/atherosclerosis in apolipoprotein E(ApoE)and LDL receptor(LDLR)dual deficient(ApoE^(–/–)LDLR^(–/–))mice and investigated the effect of CDDP or CDDP plus a low dose of simvastatin on the heart failure.CDDP or CDDP plus a low dose of simvastatin inhibited heart injury by multiple actions including anti-myocardial dysfunction and anti-fibrosis.Mechanistically,both Wnt and lysine-specific demethylase 4A(KDM4A)pathways were significantly activated in mice with heart injury.Conversely,CDDP or CDDP plus a low dose of simvastatin inhibited Wnt pathway by markedly up-regulating expression of Wnt inhibitors.While the anti-inflammation and anti-oxidative stress by CDDP were achieved by inhibiting KDM4A expression and activity.In addition,CDDP attenuated simvastatin-induced myolysis in skeletal muscle.Taken together,our study suggests that CDDP or CDDP plus a low dose of simvastatin can be an effective therapy to reduce hypercholesterolemia/atherosclerosis-induced heart failure.

Deciphering chemical and metabolite profiling of Chang-Kang-Fang by UPLC-Q-TOF-MS/MS and its potential active components identification

Chang-Kang-Fang(CKF)formula,a Traditional Chinese Medicine(TCM)prescription,has been widely used for the treatment of irritable bowel syndrome(IBS).However,its potential material basis and underlying mechanism remain elusive.Therefore,this study employed an integrated approach that combined ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry(UPLC-Q/TOF-MS)with network pharmacology to systematically characterize the phytochemical components and metabolites of CKF,as well as elucidating its underlying mechanism.Through this comprehensive analysis,a total of 150 components were identified or tentatively characterized within the CKF formula.Notably,six N-acetyldopamine oligomers from Cicadae Periostracum and eight resin glycosides from Cuscutae Semen were characterized in this formula for the first time.Meanwhile,149 xenobiotics(58 prototypes and 91 metabolites)were detected in plasma,urine,feces,brain,and intestinal contents,and the in vivo metabolic pathways of resin glycosides were elaborated for the first time.Furthermore,network pharmacology and molecular docking analyses revealed that alkaloids,flavonoids,chromones,monoterpenes,N-acetyldopamine dimers,p-hydroxycinnamic acid,and Cus-3/isomer might be responsible for the beneficial effects of CKF in treating IBS,and CASP8,MARK14,PIK3C,PIK3R1,TLR4,and TNF may be its potential targets.These discoveries offer a comprehensive understanding of the potential material basis and clarify the underlying mechanism of the CKF formula in treating IBS,facilitating the broader application of CKF in the field of medicine.

China’s Experience and Challenges in EU Registration and Declaration

Hello everyone, I would like to share with you the declaration of the phytomedicine produced by Tasly. There are three parts: The first is the company introduction. It is hoped that Chinese companies and European companies, can have further cooperation opportunities. Next, I will give a brief introduction to our company.

Panel Discussion

IMPACT OF BREXIT ON CHINESE COMPANIES' ACCESS TO THE EUROPEAN MARKET Q: We have a product, which was approved in UK in 2017. Now we want to expand the market to the Europe. Do you have any suggestions about which country is easier to accept traditional Chinese medicine?
