The correlation coefficients in pre-diction set are 0.9997 and 0.9969, prediction results are accurate and reliable. This method can be applied in rapid analysis of heat- clearing and detoxicating oral liquid, and it is fit for on-line detection and has a wide application prospect.

Research progress of heat-clearing and dampness-removing method to improve the inflammatory microenvironment of gout

Gout is a metabolic bone and joint disease caused by purine metabolism disorder.The disturbance of inflammatory microenvironment caused by monosodium urate(MSU)deposition is an important pathological mechanism of gout occurrence and development.In the understanding of Traditional Chinese medicine(TCM),the interaction of"dampness","heat"and"stasis"is the main pathogenesis of gout,and the method of clearing heat and removing dampness is the main treatment method of TCM for gout.In recent years,studies have found that heat-clearing and dampness-removing method can improve the TCM symptom score of gout patients,especially in the body tiredness,dry mouth and dry throat,short yellow urine,thirsty,etc.,which are the characteristics of dampness and heat syndrome,this may be related to the fact that the TCM heat-clearing and dampness-removing method in the treatment of gout removes the appearance of dampness and heat,improves the inflammatory microenvironment of gout and restores the normal metabolic function of human body.This paper deeply explores the specific mechanism of TCM heat-clearing and dampness-removing method to improve the inflammatory microenvironment of gout,which can provide new ideas for the diagnosis and treatment of clinical gout.

Network pharmacology-based analysis of heat clearing and detoxifying drug JC724 on the treatment of colorectal cancer

BACKGROUND Heat-clearing and detoxifying drugs has protective effect on colorectal cancer(CRC).Given the complicated features of Traditional Chinese medicine formulas,network pharmacology is an effective approach for studying the multiple interactions between drugs and diseases.AIM To systematically explore the anticancer mechanism of heat-clearing and detoxifying drug JC724.METHODS This study obtained the active compounds and their targets in JC724 from Traditional Chinese Medicine System Pharmacology Database.In addition,the CRC targets were obtained from Drugbank,TTD,DisGeNET and GeneCards databases.We performed transcriptome analysis of differentially expressed genes in CRC treated with JC724.Venn diagram was used to screen the JC724-CRC intersection targets as candidate targets.Core targets were selected by proteinprotein interaction network and herb ingredient-target-disease network analysis.The functional and pathway of core targets were analysed by enrichment analysis.RESULTS We found 174 active ingredients and 283 compound targets from JC724.940 CRC-related targets were reserved from the four databases and 304 CRC differentially expressed genes were obtained by transcriptome analysis.We constructed the network and found that the five core ingredients were quercetin,βBeta sitosterol,wogonin,kaempferol and baicalein.The core JC724-CRC targets were CYP1A1,HMOX1,CXCL8,NQO1 and FOSL1.JC724 acts on multiple signaling pathways associated with CRC,including the Nrf2 signaling pathway,oxidative stress,and the IL-17 signaling pathway.CONCLUSION In this study,we systematically analyzed the active ingredients,core targets and main mechanisms of JC724 in the treatment of CRC.This study could bring a new perspective to the heat-clearing and detoxifying therapy of CRC.

Antipyretic Effects of Liposoluble Fractions of Viola yedoensis

Objective To clarify the antipyretic effect of the Chinese materia medica, Violae Herba （Viola yedoensis）, and its active fractions by examining the effects of V. yedoensis extracts with differing polarities on body temperature, total white blood cell （WBC） count, WBC differential count, and total serum complement of rabbits with lipopolysaccharide （LPS）-induced fever. Methods The rabbits were treated with water and ethanolic extracts of V. yedoensis, as well as petroleum ether, ethyl acetate, and n-butanol fractions of the ethanolic extract at low-, mid- and high- doses. The LPS was injected via the ear vein of rabbits in model and treatment groups 30 min post-gavage. Their body temperature was measured at 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, 5.0, 5.5, and 6.0 h after the LPS challenge to calculate the temperature changes and thermal response index. After the last temperature measurement, blood samples were collected to determine the blood cell counts and total serum complement （CHs0） level. Results Compared with the model group, body temperature was significantly lower in the low-dose ethanolic extract group, low- and mid-dose petroleum ether fraction groups, and all three ethyl acetate fraction groups. Serum CHs0 levels were lower in all treatment groups, except the ethanolic extract groups, than that in the model group, with no significant difference. V. yedoensis had no significant effect on the blood cells of febrile rabbits challenged with LPS for 6 h. Conclusion The antipyretic effects of V. yedoensis are strong, and its active fractions are the petroleum ether and ethyl acetate fractions of ethanolic extract.
