A brief overview of traditional Chinese medicine prescription powered by artificial intelligence

Traditional Chinese medicine prescription is one of the treasures of traditional Chinese medicine(TCM).There are tens of thousands TCM prescriptions accumulated in the past thousands of years,corresponding to different diseases,symptoms and therapeutic goals.The correspondences are so complicated that there is an urgent need to leverage new technologies such as artificial intelligence(AI)to analyze,understand and utilize them effectively.In this paper,we present a brief overview of this direction,where current research progress on TCM prescription powered by AI is summarized.Our summarization focuses on three aspects,TCM prescription mining that aims at understanding the TCM prescription,TCM prescription or herb knowledge base construction that aims at extracting knowledge to support the TCM prescription-related study,and TCM prescription discovery that aims at utilizing AI technologies to further energize TCM.It is encouraging to see that steady progress in this direction has been made recently.Besides,a toy experiment on image-based TCM herb recognition by using convolutional neural networks is also conducted.It basically verifies that it is promising to use AI technologies to address challenging tasks in TCM.We also point out several research topics that could be cooperatively performed by researchers from the two disciplines.

Effects of Traditional Chinese Herbal Medicine on Immune Organ Indexes and Macrophages Phagocytic Indexes in Chickens Infected by Infectious Bronchitis Virus

[ Objective] To study the therapeutic effects of traditional Chinese medicine prescriptions on infectious bronchitis （IB） and find a novel avenue for prevention and treatment of viral diseases in poultry. [Method] A total of 160 cockerels at the age of 15 d were divided into four groups randomly, including traditional Chinese medicine group, moroxydine control group, challenge control group and healthy control group. Except the healthy control group, other groups were challenged with infectious bronchitis virus （IBV） on Day 15. After 48 h post challenge, the traditional Chinese medicine groupand moroxydine control group were respectively administrated with Chinese herbal medicine prescription and moroxydine, continuously for 5 d. The immune organ indexes and macrephage phagocytic indexes were detected on Day 18, 24 and 30, respectively. [ Result] The immune organ indexes and macrophage phagocytic indexes were not significantly different between traditional Chinese medicine group and moroxydine control group on Day 18. But all the indexes of the traditional Chinese medicine groups were increased significantly （ P 〈 0.05） on Day 24 and 30, and showed extremely significant difference （ P 〈 0.01 ） with those of challenge control group on Day 30. [ Conclusion] The traditional Chinese herbal medicine can enhance macrophage phagocytic indexes and immune organs indexes of chickens infected by IBV.

Value and influencing factors of valid Traditional Chinese Medicine compound prescription patents for mammary gland hyperplasia

OBJECTIVE: To explore the value and factors influencing the maintenance of valid Traditional Chinese Medicine compound prescription patents for the management of mammary gland hyperplasia. METHODS: The State Intellectual Property Office Patents Database, China Patent Information Center Patents Database, Soopat Patent Search Platform, and CNIPR Search Platform of Chinese and Foreign Patent Database were searched to identify Traditional Chinese Medicine compound prescription patents for mammary gland hyperplasia that had been maintained for at least 5 years. Logistic regression analysis was used to detect the factors influencing the maintenance of valid patents. RESULTS: From 1 January 1993 to 31 December 2019, a total of 1228, Traditional Chinese Medicine compound prescription patents for mammary gland hyperplasia were authorized. Of these applications, 381 patents were granted and only 176 patents were maintained for more than 5 years. The five independent variables assessed in this study all had significant explanatory functions. CONCLUSIONS: The maintenance of valid patents for Traditional Chinese Medicine compound prescriptions for treating mammary gland hyperplasia is of great importance. The maintenance of such patents depends on many factors, such as the concentration of effective herbs, number of dependent claims, provision of new dosage forms and detailed experimental data, and transfer of patent rights.

Recent advances of traditional Chinese medicine on the prevention and treatment of COVID-19

Coronavirus disease-2019(COVID-19)is a new highly infectious disease caused by a novel coronavirus.Recently,the number of new cases infected pneumonia in the world continues to increase,which has aroused great concern from the international community.At present,there are no small-molecule specific anti-viral drugs for the treatment.The high mortality rate seriously threatens human health.Traditional Chinese medicine(TCM)is a unique health resource in China.The combination of TCM and Western medicine has played a positive and important role in combating COVID-19 in China.In this review,through literature mining and analysis,it was found that TCM has the potential to prevent and treat the COVID-19.Then,the network pharmacological studies demonstrated that TCM played roles of anti-virus,anti-inflammation and immunoregulation in the management of COVID-19 via multiple components acting on multiple targets and multiple pathways.Finally,clinical researches also confirmed the beneficial effects of TCM on the treatment of patients.This review may provide meaningful and useful information on further drug development of COVID-19 and other viral infectious diseases.

Simultaneous Determination of Six Compounds in Rat Plasma by Ultra-Performance Liquid Chromatography with Tandem Mass Spectrometry: Application in the Pharmacokinetic Study of Qing Gan-Shu Yu-Fang

A rapid and high selective ultra-performance liquid chromatography(UPLC)with tandem mass spectrometry method for simultaneous determination of six compounds including albiflorin,paeoniflorin,picroside I,picroside II,saikosaponin A,and saikosaponin D in rat plasma was developed and validated using butyl p-hydroxybenzoate as an internal standard.One-step direct protein precipitation with acetonitrile was used to extract the compounds from the rat plasma samples.Chromatographic separation was achieved using an ACQUITY UPLC BEH C18 column(100 mm×2.1 mm,1.7μm)at a flow rate of 0.4 m L/min,using gradient mode containing 0.1%formic acid in water and acetonitrile were used as the Mobile phase A and B.Electrospray ionization in negative ion mode and multiple reaction monitoring were used to identify and quantify active components.Calibration curves showed good linearity(R^2>0.9908)over a wide concentration range for all compounds.The intra-and interday precision(relative standard deviation)ranged 2.4%–7.0%and 2.6%–8.0%,respectively.The accuracy(relative error)was from-13.0%to 13.2%at all quality control levels.The recovery ranged from 81.1%to 92.5%.The validated method was successfully applied to pharmacokinetic study in rats after oral administration of Qing Gan-Shu Yu-Fang.The results show that one can draw a conclusion that these six active ingredients can be quickly absorbed and play a pharmacodynamic role rapidly in vivo.
