An ultra-robust fingerprinting method for quality assessment of traditional Chinese medicine using multiple reaction monitoring mass spectrometry

Chromatographic fingerprinting has been perceived as an essential tool for assessing quality and chemical equivalence of traditional Chinese medicine.However,this pattern-oriented approach still has some weak points in terms of chemical coverage and robustness.In this work,we proposed a multiple reaction monitoring(MRM)-based fingerprinting method in which approximately 100 constituents were simultaneously detected for quality assessment.The derivative MRM approach was employed to rapidly design MRM transitions independent of chemical standards,based on which the large-scale fingerprinting method was efficiently established.This approach was exemplified on QiShenYiQi Pill(QSYQ),a traditional Chinese medicine-derived drug product,and its robustness was systematically evaluated by four indices:clustering analysis by principal component analysis,similarity analysis by the congruence coefficient,the number of separated peaks,and the peak area proportion of separated peaks.Compared with conventional ultraviolet-based fingerprints,the MRM fingerprints provided not only better discriminatory capacity for the tested normal/abnormal QSYQ samples,but also higher robustness under different chromatographic conditions(i.e.,flow rate,apparent pH,column temperature,and column).The result also showed for such large-scale fingerprints including a large number of peaks,the angle cosine measure after min-max normalization was more suitable for setting a decision criterion than the unnormalized algorithm.This proof-of-concept application gives evidence that combining MRM technique with proper similarity analysis metrices can provide a highly sensitive,robust and comprehensive analytical approach for quality assessment of traditional Chinese medicine.

Use of traditional Chinese medicine in the treatment of immune-related adverse events of cancer immunotherapy

Immune checkpoint inhibitors(ICPI)have shown considerable promise in the treatment of tumors.However,immune-related adverse events(irAEs)caused by ICPI have been reported in nearly every organ system.Whilst this represents a new challenge in the field of cancer treatment,traditional Chinese medicine(TCM)provides benefits in the treatment of irAEs.This article reviews the studies of the treatment of immune-related gastrointestinal diseases and dermatosis with TCM and introduces the collaborative efforts between China and France in the implementation of TCM for the treatment of irAEs.

Analysis of the law of traditional Chinese medicine in prevention and treatment of gastrointestinal reaction caused by lung cancer chemotherapy

Objective:To explore the law of traditional Chinese medicine in prevention and treatment of gastrointestinal reaction after chemotherapy for lung cancer.Methods:The literatures on prevention and treatment of gastrointestinal reaction after chemotherapy with Chinese medicine were searched from CNKI,Wanfang and VIP databases from the establishment of the database to September 2020.After screening,the database was established,and data mining was conducted by using IBM SPSS statistics 20.0 and IBM SPSS modeler 18.0 to summarize the medication rules of traditional Chinese medicine in the prevention and treatment of gastrointestinal reaction after chemotherapy for lung cancer.Results:(1)A total of 131 literatures involving 245 traditional Chinese medicines were included for data mining;(2)High frequency drugs include Astragalus membranaceus,liquorice,Poria cocos,Atractylodes macrocephala,Pinellia ternata,Codonopsis pilosula,Ophiopogon japonicus,coix seed,Pericarpium Citri Reticulatae,Radix Glehniae and so on;(3)The traditional Chinese medicine used is mainly tonifying deficiency medicine,resolving phlegm and relieving cough and asthma medicine,diuresis and dampness medicine,heat clearing medicine and antiphlogistic medicine.The medicine tastes bitter and sweet,and has cold and warm properties.The meridian tropism involves liver,lung,stomach,spleen and kidney;(4)Seven core TCM combinations were obtained by cluster analysis,and 24 drug pairs(groups)were obtained by association rule analysis.Conclusion:Through the data mining of traditional Chinese medicine for the prevention and treatment of gastrointestinal reaction after chemotherapy for lung cancer,we can find out the potential rules of traditional Chinese medicine prescription,and clarify the core Chinese medicine,which is helpful to provide certain reference for the development and research of drugs for the treatment of gastrointestinal reaction and modern clinical practice.

The effects of Chinese herbal medicines on Madopar dose and adverse reaction during the maintenance phase of Parkinson's disease:a systematic review with meta-analysis

Background:Parkinson’s disease is a progressive neurodegenerative disease,and is usually treated with levodopa combined with dopa decarboxylase inhibitor like Madopar.In order to improve the efficacy and reduce adverse reactions,Chinese herbal medicines are usually applied with Madopar to treat Parkinson’s disease in clinic.According to the results of certain randomized controlled trials,levodopa drugs combined with Chinese herbal medicines could achieve better effects like the improvement of clinical symptoms,the reduced incidence of adverse reactions,and the reduced dose of levodopa drugs(especially in the maintenance phase).However,not all the randomized controlled trials showed favorable effect on Parkinson’s disease.Therefore,it is necessary to find out how to effectively combine Chinese herbal medicines with Madopar.In order to evaluate the effects of Chinese herbal medicines on Madopar dose and adverse reaction during the maintenance phase of Parkinson’s disease,a meta-analysis was conducted.Methods:A systematic research was carried out for randomized controlled trials of combined Chinese herbal medicines and Madopar treatment for Parkinson’s disease during the maintenance phase published till August 2019.The primary outcome was the Madopar dose and secondary outcome was the incidence of adverse reaction.Data were pooled and analyzed with RevMan 5.3.Results:A total of 18 studies were included with 1,169 cases.However,study quality evaluation showed low methodological quality.Meta-analyses showed that the dose of Madopar in the treatment group was significantly lower than that in the control group,and the incidence of adverse reactions in the treatment group was also significantly lower than that in the control group.However,the correlation analysis showed that the reduction of Madopar dose was not related to the reduction of incidence of adverse reactions(P>0.05).There existed publication bias on the primary outcome and secondary outcome.Conclusions:Chinese herbal medicines could reduce the Madopar dose and adverse reaction during the maintenance phase of Parkinson’s disease treatment.This conclusion must be considered cautiously,for lack of studies of high quality.

Studies on the Degranulation of RBL-2H3 Cells Induced by Traditional Chinese Medicine Injections

Aims: To study RBL-2H3 cell degranulation phenomena induced by some TCMIs through cell morphological and ultra-structural observation, released enzyme activity and establish RBL-2H3 cell degranulation test indicated by β- hexosaminidase activity as a method to evaluate TCMIs at nonclinical stage. Methods: RBL-2H3 cells were used to study the degranulation by co-culture with positive control C48/80 and some TCMIs through morphological and ultra-structure observation, β-hexosaminidase activity detection. RBL-2H3 cell degranulation test was established to detect β-hexosaminidase activity caused by 17 kinds of TCMIs and their ingredients. The cytotoxicity effect of some TCMIs on both RBL 2H3 and BRL cells was measured by CCK-8 assay. Results: Toluidine blue staining and ultra-structure of electronic microscope observation of treated RBL-2H3 cells showed degranulation morphologically. Detection of β-hexosaminidase activity in the supernatant of treated cells showed some TCMIs had elevated enzyme release rates. Further analysis of the ingredients and compound in Tanreqing Injection and Shengmai Injection showed Scutellaria baicalensis Georgi in Tanreqing Injection, Red ginseng and Fructus Schisandrae Chinensis in Shengmai Injection were responsible to the degranulation of RBL-2H3 cells. Osmotic pressures and pH influenced RBL-2H3 degranulation. High Osmotic pressure of Tanreqing Injection and low pH of chlorogenic acid at 2.5 and 5.0 mmol/L congcentration might be responsible to high β-hexosaminidase activity. Most of the TCMIs inducing degranulation had cytotoxicity effect for both RBL-2H3 and BRL cells, but some TCMIs inducing degranulation had no cytotoxicity effect. Conclusion: Some TCMIs can induce degranulation of RBL-2H3 cells;RBL-2H3 cell degranulation test can be used in non-clinical stage to detect the risk causing anaphylactoid reactions. Osmotic pressures and pH influenced RBL-2H3 degranulation, and they should be measured before testing. The mechanism of degranulation caused by some TCMIs is cytotoxic, and some are non-cytotoxic and may be through exicytosis.

A meta-analysis of Chinese herbal medicines for vascular dementia

OBJECTIVE： To investigate the efficacy and safety of Chinese herbal medicines in the treatment of patients with vascular dementia. DATA RETRIEVAL： We retrieved publications from Cochrane Library （2004 to July 2011）, PubMed （1966 to July 2011）, the Chinese Science and Technique Journals Database （1977 to July 2011）, the China National Knowledge Infrastructure （1979 to July 2011）, Google Scholar （July 2011）, and the Chinese Biomedical Database （1977 to July 2011） using the key words ＂Chinese medicine OR Chinese herbal medicine＂ and ＂vascular dementia OR mild cognition impair OR multi-infarct dementia OR small-vessel dementia OR strategic infarct dementia OR hypoperfusion dementia OR hemorrhagic dementia OR hereditary vascular dementia＂. SELECTION CRITERIA： Randomized controlled trials comparing Chinese herbal medicines with placebo/western medicine in the treatment of patients with vascular dementia were included. Diagnostic standards included Diagnostic and Statistical Manual of Mental Disorders-IV, and National Institute of Neurological Disorders and Stroke and Association Internationale pour la Recherche et I＇Enseignement en Neurosciences. Two participants independently conducted literature screening, quality evaluation and data extraction. The quality of each trial was assessed according to the Cochrane Reviewers＇ Handbook 5.0. MAIN OUTCOME MEASURES： Effective rate, Mini-Mental State Examination scores, Hasegawa Dementia Scale scores, and incidence of adverse reactions. RESULTS： We identified 1 143 articles discussing the effects of Chinese medicine on vascular dementia. Thirty-one of these were included in the analysis. These studies involved a total of 2 868 participants （1 605 patients took Chinese medicine decoctions （treatment group）; 1 263 patients took western medicine or placebo）. The results of our meta-analysis revealed that Chinese herbal remedies in the treatment group were more efficacious than the control intervention （relative risk （RR） = 1.27; 95% confidence interval （C/）： 1.18-1.38, P 〈 0.01）. Mini-Mental State Examination scores were higher in patients taking Chinese herbal medicines than in those in the control group （weighted mean difference （WMD） = 2.83; 95%CI： 2.55-3.12, P 〈 0.01）. Patients in the treatment group showed better disease amelioration than those in the control group （Hasegawa Dementia Scale scores; WMD = 2.41, 95%CI： 1.48-3.34, P 〈 0.01）. There were also considerably fewer adverse reactions among those in the treatment group compared with those in the control group （RR = 0.20, 95%CI： 0.08-0.47, P 〈 0.01）. CONCLUSION： Chinese herbal medicine appears to be safer and more effective than control measures in the treatment of vascular dementia. However, the included trials were generally low in quality. More well-designed, high-quality trials are needed to provide better evidence for the assessment of the efficacy and safety of Chinese medicines for vascular dementia.

The dynamic changes and mechanisms of Rehmanniae radix processing based on Maillard reaction

Background:Traditional Chinese medicines are usually processed before they are used for clinical treatment.This is done in a way associated with the Maillard reaction.Methods:Based on the Maillard reaction,this paper analyzed the degree of processing of rehmannia root(Rehmanniae radix)relative to the dynamic variation rules of Maillard reaction index parameters,including pH,A420,amino acids,and 5-hydroxymethylfurfural.Furthermore,this study introduced thermal analysis techniques and pyrolysis kinetics to assess the influence of the correlation between processing raw rehmannia root and the Maillard reaction during carbonization.It then went through the whole process of transforming the raw material to end-product in order to explain the scientific connotation of processing it.Results:The results showed that each time rehmannia root was processed,its pH value and amino acid content decreased,while the A420 value and 5-HMF increased.Processing with wine shows a significant difference in these experimental indexes.The position and intensity of the maximum thermal weight loss rate peak of processed rehmannia root at different degrees of processing are different.Comprehensive quantitative 221±0.2°C for processed rehmannia root carbonization was the processing temperature limit.Moreover,the kinetic solution verified that the activation energy corresponding to the carbonization temperature was close to the maximum value of the activation energy of the whole carbonization process,and the optimal mechanism function was g(α)=((1−α)−1/3−1)2.Conclusion:The Maillard reaction occurred during the processing of rehmannia root mixed with carbonization.With each increase of the number of steaming and drying cycles involved in the processing,the level of Maillard reaction increased significantly.The wine-steaming method had a significant effect on the quality of the processed product.

目的探究金松双黄酮(SCI)调控酪氨酸激酶2/信号转导与转录激活因子3(JAK2/STAT3)通路,对脂多糖(LPS)诱导的BV2小胶质细胞炎症反应的影响。方法①采用格里斯(Griess)试验试剂检测不同浓度SCI(1.25~40μmol·L^(-1))干预对经LPS刺激后BV2小胶质细胞培养液中亚硝酸盐含量的影响。②采用四甲基偶氮唑盐比色法(MTT)检测不同浓度SCI(1.25~40μmol·L^(-1))干预的BV2小胶质细胞活性以此判断SCI对BV2小胶质细胞毒性作用。③将BV2小胶质细胞以2×10^(6)个/孔接种于6孔板中,并将其随机分为对照组(Ctrl组)、对照+SCI组(Ctrl+SCI组)、模型组(LPS组,100μg·L^(-1))、模型+SCI组(LPS+SCI组),各组进行相应干预。采用实时荧光定量逆转录聚合酶链式反应(RT-qPCR)法检测SCI对LPS刺激BV2细胞的促炎因子肿瘤坏死因子-α(TNF-α)和诱导一氧化氮合酶(iNOS)mRNA表达的影响;酶联免疫吸附测定(ELISA)法检测白介素-6(IL-6)、TNF-α的蛋白水平;Western blot法检测JAK2/STAT3信号通路磷酸化酪氨酸激酶2(p-JAK2)、磷酸化信号转导与转录激活因子3(p-STAT3)以及iNOS蛋白表达。结果①Greiss法结果显示,1.25~40μmol·L^(-1) SCI均显著降低LPS刺激的BV2小胶质细胞产生的亚硝酸盐(P<0.05)。②MTT法结果显示,1.25~20μmol·L^(-1)浓度的SCI对BV2小胶质细胞的活性没有影响。③RT-qPCR结果显示,与LPS组比较,LPS+SCI组中iNOS、TNF-αmRNA的表达量下降(P<0.05);ELISA法结果显示,与LPS组比较,LPS+SCI组中IL-6、TNF-α的蛋白表达量下降(P<0.05);Western blot结果显示,与LPS组比较,LPS+SCI组中p-JAK2、p-STAT3、iNOS蛋白表达降低(P<0.05)。结论SCI能够通过抑制JAK2/STAT3信号通路发挥对LPS刺激的BV2小胶质细胞的抗炎作用。
