Systems Theory-Driven Framework for AI Integration into the Holistic Material Basis Research of Traditional Chinese Medicine

This paper introduces a systems theory-driven framework to integration artificial intelligence(AI)into traditional Chinese medicine(TCM)research,enhancing the understanding of TCM’s holistic material basis while adhering to evidence-based principles.Utilizing the System Function Decoding Model(SFDM),the research progresses through define,quantify,infer,and validate phases to systematically explore TCM’s material basis.It employs a dual analytical approach that combines top-down,systems theory-guided perspectives with bottom-up,elements-structure-function methodologies,provides comprehensive insights into TCM’s holistic material basis.Moreover,the research examines AI’s role in quantitative assessment and predictive analysis of TCM’s material components,proposing two specific AIdriven technical applications.This interdisciplinary effort underscores AI’s potential to enhance our understanding of TCM’s holistic material basis and establishes a foundation for future research at the intersection of traditional wisdom and modern technology.

Antioxidant Activity of 50 Traditional Chinese Medicinal Materials Varies with Total Phenolics

This study was designed to determine the total phenolic content of 50 herbs and to examine their antioxidant potential. In the sample preparation, 60% ethanol was chosen as the extraction solvent for the subsequent experiments. Folin-Cicolteau phenol reagent and a colorimetric method were used to determine the total phenolic content of the selected herbs. The result showed that total phenolic content of those herbs ranged from 2 to 185 mg/g. In antioxidant assay, the ferric reducing/antioxidant power (FRAP) values ranged from 2 to 134 mg GAE/g;the IC50 values of DPPH?·, ·OH and ?scavenging were in the range of 0.06 - 5.50 mg/mL, 0.017 - 0.636 mg/mL and 0.050 - 0.681 mg/mL respectively. Flos caryophylli was the exceptant in the ?scavenging assay because there was no linear relation between the concentration and the scavenging percentage. Compared to gallic acid, ascorbic acid and butylated hydroxytoluene (BHT) in antioxidant assay as positive control, the most potential antioxidant herbs were Cacumen platycladi, Radix et Rhizoma rhei, Rhizoma rhodiolae crenulatae, and Rhizoma sanguisorbae with considerable content of phenolics. Especially, a positive and significant correlation was found between the total phenolic content and FRAP value or DPPH· scavenging percentage.

Reason Analysis and Risk Prevention of Soaring Price of Traditional Chinese Medicinal Materials

In recent years,the price of traditional Chinese medicinal materials soars continuously,and the resulting price risk increasingly looms large,which has critically affected midstream and downstream industries and peoples' demand for drug,and imperiled healthy and orderly development of traditional Chinese medicinal industries.Based on the status quo of continuous skyrocketing price of traditional Chinese medicinal materials at present,we winkle out the root cause of soaring price as follows:the supply and demand lose balance;the production costs hike up;there are other factors responsible for soaring price.This paper further analyses the impact of sharp increase in price of traditional Chinese medicinal materials on all links of industry chain as follows:the medicinal herb growers never benefit from soaring price;the counterfeiters and forgers in midstream industry increase;the gross profit rate of Chinese medicine enterprises declines.In accordance with the risk arising from abnormal fluctuation in price of traditional Chinese medicinal materials,corresponding precautionary measures are put forward as follows:promote the quality of traditional Chinese medicinal materials through management of value chain;curtail the production and management cost of traditional Chinese medicinal materials through management of organization chain;stabilize price of traditional Chinese medicinal materials through management of information chain;reduce transaction cost of traditional Chinese medicinal materials through management of logistics chain.

Bioactive constituents of animal-derived traditional Chinese medicinal materials for breast cancer:opportunities and challenges

Breast cancer is globally the most common invasive cancer in women and remains one of the leading causes of cancer-related deaths.Surgery,radiotherapy,chemotherapy,immunotherapy,and endocrine therapy are currently the main treatments for this cancer type.However,some breast cancer patients are prone to drug resistance related to chemotherapy or immunotherapy,resulting in limited treatment efficacy.Consequently,traditional Chinese medicinal materials(TCMMs)as natural products have become an attractive source of novel drugs.In this review,we summarized the current knowledge on the active components of animal-derived TCMMs,including Ophiocordyceps sinensis-derived cordycepin,the aqueous and ethanolic extracts of O.sinensis,norcantharidin(NCTD),Chansu,bee venom,deer antlers,Ostrea gigas,and scorpion venom,with reference to marked anti-breast cancer effects due to regulating cell cycle arrest,proliferation,apoptosis,metastasis,and drug resistance.In future studies,the underlying mechanisms for the antitumor effects of these components need to be further investigated by utilizing multi-omics technologies.Furthermore,large-scale clinical trials are necessary to validate the efficacy of bioactive constituents alone or in combination with chemotherapeutic drugs for breast cancer treatment.

Gaps and feasibility of fixed-dose combination strategy in the development of modern Chinese medicine

isTraditional Chinese medicine(TCM)is a highly complex chemical substance system,which not only reflected in the complexity of the chemical components and their interrelationships,but also in the intricacy of the prescription’s connection with the human body.Component compatibility strategy has been proposed for developing modern TCM since 2005 and established comprehensive relevant technologies and research approaches.Moreover,to meet the safety and efficacy of current pharmaceuticals,research on fixed-dose combination drugs is directed by modern scientific theories,conforms to TCM compatibility principles and clarifies material basis and pharmacological mechanisms and component-effect correlations.This review summarized gaps and feasibility of fixed-dose combination strategy in the development of modern TCM research and assessed their advantages and disadvantages in light of contemporary drug combination research practices.

Network pharmacology approaches for research of Traditional Chinese Medicines

Pharmacodynamics material basis and effective mechanisms are the two main issues to decipher the mechnisms of action of Traditional Chinese medicines(TCMs)for the treatment of diseases.TCMs,in“multi-component,multi-target,multi-pathway”paradigm,show satisfactory clinical results in complex diseases.New ideas and methods are urgently needed to explain the complex interactions between TCMs and diseases.Network pharmacology(NP)provides a novel paradigm to uncover and visualize the underlying interaction networks of TCMs against multifactorial diseases.The development and application of NP has promoted the safety,efficacy,and mechanism investigations of TCMs,which then reinforces the credibility and popularity of TCMs.The current organcentricity of medicine and the“one disease-one target-one drug”dogma obstruct the understanding of complex diseases and the development of effective drugs.Therefore,more attentions should be paid to shift from“phenotype and symptom”to“endotype and cause”in understanding and redefining current diseases.In the past two decades,with the advent of advanced and intelligent technologies(such as metabolomics,proteomics,transcriptomics,single-cell omics,and artificial intelligence),NP has been improved and deeply implemented,and presented its great value and potential as the next drug-discovery paradigm.NP is developed to cure causal mechanisms instead of treating symptoms.This review briefly summarizes the recent research progress on NP application in TCMs for efficacy research,mechanism elucidation,target prediction,safety evaluation,drug repurposing,and drug design.
