OBJECTIVE To establish a extraction process of Changyan Heji Ⅱ(CYHJ-Ⅱ)based on UPLC-Q-TOF-MS/MS technology combined with response surface analysis,and to optimize the extraction process.METHODS The chemical components in CYHJ-Ⅱ were qualitatively analyzed by UPLC-Q-TOF-MS/MS technology,and the chemical components with good linear relation-ship in mass spectrometry response were selected as process investigation indicators;the extraction process parameters(water addition amount,extraction time and soaking time)were investigated by Box-Behnken design;the comprehensive score was obtained by princi-pal component analysis(PCA),and the optimal process was determined by the comprehensive score combined with response surface a-nalysis.RESULTS Through qualitative analysis,110 components were inferred and identified from CYHJ-Ⅱ,including 2 organic acids,82 flavonoids,13 terpenoids,and 13 alkaloids.Based on the results of qualitative analysis,48 index components with good lin-ear relationships were derived by UPLC-Q-TOF-MS/MS combined with Masshunter mass spectrometry data analysis software.PCA was performed and the comprehensive score was calculated.Response surface analysis was performed with the comprehensive score as an indicator.The optimal extraction process obtained by combining the response surface prediction results and actual production was:soaking for 45 min,8 times the amount of solvent,2 extractions,each time for 120 min.CONCLUSION This study provides a new idea for the investigation of the extraction process of traditional Chinese medicine compound prescriptions and expands a new method for the development of traditional Chinese medicine compound prescriptions.

OBJECTIVE To prepare the volatile oil cyclodextrin inclusion compound of Wenjing Decoction to improve its stability and characterize its formation;to compare the inclusion behavior of cinnamaldehyde,paeonol and ligustilide in volatile oil of Wenjing Decoction with different cyclodextrins;and to study the effect of different cyclodextrins on the inclusion of multiple components in the volatile oil of Wenjing Decoction.METHODS The inclusion compounds of volatile oil β-CD and its 5 derivatives in Wenjing Decoc-tion were prepared by ultrasonic method,and the inclusion rate of each component was determined by HPLC.TGA and FT-IR were used to characterize the formation of the inclusion complex.The inclusion behavior and influencing factors were studied by phase solu-bility test and molecular docking.RESULTS The inclusion compounds of volatile oil β-CD and its derivatives in Wenjing Decoction were successfully prepared.TGA results showed that the thermal stability of volatile oil in Wenjing Decoction was improved after inclu-sion by cyclodextrin.FT-IR results showed that some components of the volatile oil were bonded to cyclodextrin through non-covalent bonds such as hydrogen bonds.The results of phase solubility test showed that the three main components in the volatile oil of Wenjing Decoction were combined with β-CD in the molar ratio of 1∶n(n≥1),and with β-CD derivatives in the molar ratio of 1∶1.The re-sults of molecular docking showed that the benzene rings of cinnamaldehyde and paeonol,and lactone rings of ligustilide penetrated into the cyclodextrin cavity to form clathrates.The inclusion rates of β-CD and its derivatives for each component in the volatile oil of Wen-jing Decoction were DM-β-CD>HP-β-CD>β-CD>HE-β-CD>SBE-β-CD>CM-β-CD,which were consistent with the af-finity of phase solubility test and molecular docking.The inclusion rates of the three components with β-CD and its derivatives were cinnamaldehyde>paeonol>ligustilide,which was consistent with the concentration of each component in the volatile oil,but the affin-ity order was opposite to that obtained by phase solubility test and molecular docking.CONCLUSION β-CD and its derivatives can successfully incorporate the volatile oil of the decoction.The components of the volatile oil and cyclodextrin are combined to form the inclusion compound by hydrogen bonding and other non-covalent bonding forces,which increases the stability of the volatile oil.The inclusion rate of volatile oil with different cyclodextrins is related to the affinity between volatile components and cyclodextrins and the concentration of volatile components,which provides a way to ensure the consistency between the main component of volatile oil inclu-sion compound in Wenjing Decoction and the reference sample.

OBJECTIVE To analyze the ethanol extracts,total phenols,total flavonoids contents and HPLC fingerprints of typi-cal propolis samples from 6 foreign countries and 5 domestic regions,optimize the extraction process and evaluate the antioxidant activi-ty,so as to provide data support for improving the quality control system of propolis.METHODS The optimization of the propolis ex-traction process utilized flavonoid content as an indicator.Three flavonoid detection methods-namely,the aluminum trichloride meth-od,aluminum nitrate method,and polyamide method-were compared.The content of ethanol extract,total phenol content,and the scavenging ability of DPPH free radicals for each sample were determined.Further analysis was conducted using HPLC fingerprint pro-filing.RESULTS The propolis extract with the highest flavonoid content was obtained using 80%ethanol as the extraction solvent,operating at 50℃,with a stirring time of 3 h,ultrasonic power of 180 W,and ultrasonic time of 15 min.The aluminum trichloride method was proved to be the most effective for determining total flavonoids in propolis.While the ethanol extract,total flavonoids,and total phenols of propolis from Xinjiang,China were relatively low,their antioxidant activity exhibited superiority.HPLC analysis re-vealed,Brazilian red propolis lacked of chrysin,galangin,caffeic acid phenethyl ester and Brazilian green propolis lacked ferulic acid,apigenin,p-coumaric acid,chrysin,and pinocembrin.In contrast,the content of these four compounds in other samples varied,with the antioxidant capacity of the extracts not precisely corresponding to the compound content.CONCLUSION Propolis exhibits a complex chemical composition with significant variations among varieties.Key quality control indexes must be comprehensively consid-ered,encompassing physicochemical characteristics and biological activity.Establishing a multi-angle assessment system with a mate-rial basis-functional linkage is essential.This approach facilitates the realization of high quality and cost-effectiveness,thereby promo-ting the healthy development of the industry.

The paper summarizes the medication rules of Professor Zou Yanqin,a master of traditional Chinese medicine,in the treatment of membranous nephropathy by"sweet supplementation and bland percolation method".Professor Zou believes that spleen and kidney deficiency and damp-heat stasis are the basic pathogenesis of membranous nephropathy.The pathogenesis evolves in a com-plex way,leading to a variety of syndromes.Invigorating the spleen and kidney,clearing away damp-heat and removing blood stasis are the key to treatment.Therefore,she follows the concept of the"harmonizing method and gentle treatment"of the Menghe Medicine School and takes the"sweet supplementation and bland percolation method"as the basis of all treatment principles for membranous ne-phropathy.This article systematically expounds Professor Zou Yanqin's thinking and prescription rules for treating membranous ne-phropathy using the"sweet supplementation and bland percolation method"from three aspects:sweet and warm to tonify qi,sweet and cool to moistening,and bland flavor to promote diuresis and facilitate fluid expulsion.

By systematically reviewing the development history of organoid technology and its application examples in Chinese med-icine,this paper summarizes the specific applications of organoids in the mechanism and translation of Chinese medicine,pathological mechanisms,diagnostic techniques,and therapeutic strategies,and evaluate their advantages and limitations through literature analysis.Organoid technology provides an in vitro model that highly simulates the function of human organs for TCM research,and can simulate the multi-target and multi-pathway mechanism of action of TCM,which significantly improves the scientificity and precision of TCM in the analysis of disease mechanisms,drug screening and personalized treatment.However,it still faces challenges in stand-ardization,ethical regulation,and clinical translation.The combination of organoid technology and TCM has a broad prospect,and it is necessary to further optimize the model construction,resolve ethical issues,and promote its wide application in TCM research and clin-ical practice through technological innovation,interdisciplinary cooperation,and international regulatory coordination in the future.

It is proposed that the brain Xuanfu and the glymphatic system(GS)have commonality in physiological structure and similarity in functions such as transporting brain substances,transmitting brain information and clearing metabolites.It is believed that GS may be the substantial manifestation of the brain Xuanfu,and GS dysfunction is the key pathological link of depression.Xuanfu stagnation and Shenji dysfunction are the core pathogenesis of depression.Taking"Brain Xuanfu-GS"as the starting point,the patho-logical mechanism of depression is deeply explored,providing a theoretical basis for the clinical diagnosis and treatment of depression in traditional Chinese medicine.

OBJECTIVE To explore the potential mechanism of Cigu Xiaozhi Prescription(CGXP)in the treatment of non-alco-holic steatohepatitis(NASH)liver fibrosis.METHODS A NASH mouse model was established.The degree of liver enlargement was evaluated by calculating the liver index.Hematoxylin-eosin(HE)and Masson staining were used to observe the degree of liver fibro-sis.In addition,immunohistochemistry was employed to detect the expression of liver fibrosis-related proteins,including α-SMA,Collagen 1,MMP2,and MMP9.Western blot and qPCR techniques were used to detect the expression levels of HIF-1α,E-cadher-in,N-cadherin,Shh,Smo,Gli1,and Gli2 in the mouse liver.The alkaline hydrolysis method was used to measure the content of liv-er hydroxyproline.RESULTS CGXP could effectively reduce the liver index(P<0.001),alleviate liver enlargement and inflamma-tion,and significantly improve the pathological damage of liver tissue in mice with liver fibrosis.CGXP significantly decreased the ex-pression levels of liver fibrosis-related proteins α-SMA,Collagen 1,MMP2 and MMP9(P<0.01,P<0.000 1);reduced the levels of HIF-1α,E-cadherin,N-cadherin,Shh,Smo,Gli1,and Gli2,and the therapeutic effect of high-dose CGXP was particularly significant(P<0.05,P<0.01,P<0.001,P<0.000 1).CONCLUSION CGXP can relieve NASH liver fibrosis in mice by reducing the liver index,alleviating inflammation,and improving tissue pathological damage.The mechanism may be related to the inhibition of the Hedgehog signaling pathway,which alters the activation and proliferation of hepatic stellate cells and reduces the synthesis and dep-osition of extracellular matrix.
