Simultaneous determination of chlorogenic acid and baicalin in heat-clearing and detoxicating oral liquid by NIRS

The calibration model for simultaneous deter-mination of chlorogenic acid and baicalin in heat-clearing and detoxicating oral liquid was built by partial least squares and near infrared spectroscopy, and the method of spectral pre-treatment was discussed. Building model from calibration set obtained good results, and vali-dated by prediction. According to heat-clearing and detoxicating oral liquid from 30 batches of 6 factories, the correlation coefficient of chloro-genic acid and baicalin model are 0.9993 and 0.9923, The root mean square error of cross validation (RMSECV) are 0.467 and 0.480, and the standard Error of prediction (SEP) of chloro- genic acid and baicalin are 0.356 and 0.370 re-spectively. 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.

Toxicity of Cu and Cd in Soils and Detoxication by Additives

Results from laboratory experiments indicated that the concentrations and toxicities of both water-soluble and 0.1 M HCl-extractable Cu and Cd from soils were in the order of red soil> yellow brown earth> black earth.The toxicity of soil varied with the concentrations of metals.The form,concentration and toxicity of Cu and Cd in soils were determined by cation exchange capacity,content of organic matter and composition of clay minerals in the soil.Addition of CaCO3 could significantly decrease the concentration and toxicity of water-soluble and 0.1 M HCl-extractable Cu or Cd from the red soil,and could notably transform the Cu and Cd from the water-soluble or exchangeable form into the organic,free oxides-occluded or sulfic form.

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.

从“瘀毒”论治消渴肾病机制探析

糖尿病肾脏疾病归属于中医“消渴肾病”范畴,是消渴日久不愈所并发的疑难病症。本文通过对“瘀毒”理论分析以及对消渴肾病的发病机制探讨,认为“瘀毒”与消渴肾病关系密切,“瘀毒损伤肾络”是消渴肾病发生发展的主要病机。基于此,本文提出了消渴肾病“解毒化瘀通络”的治疗原则,并根据消渴肾病“本虚标实”的病性,祛邪不忘扶正,攻补兼施,辨证施治。同时附验案一则以佐证,以期为消渴肾病的中医治疗提供一定的借鉴。

从瘀毒互结论治颈动脉粥样硬化易损斑块

颈动脉粥样硬化易损斑块已被认为是引发缺血性脑卒中的独立危险因素,严重威胁人类健康。目前现代医学通过西药与手术治疗易损斑块有一定效果,但存在不良反应大、复发率高等问题。中医认为瘀、毒是导致动脉粥样硬化易损斑块形成的重要原因。该文通过梳理总结中医古籍中的“瘀”“毒”理论,并结合易损斑块的现代病理研究,认为“瘀”“毒”贯穿动脉粥样硬化疾病发展始终,“瘀毒互结”为易损斑块形成和发展的核心病机。早期外毒引动,浊瘀郁脉,伏毒渐生;中期热毒炽盛,毒损瘀破,“苛毒”流散;后期虚毒内生,腐瘀溃疡,积癥成瘀。“活血解毒”应为易损斑块的治疗大法,在疾病早、中、后期分别理气活血解毒、清热活血解毒、补气活血解毒,并列举方药,以期为颈动脉粥样硬化易损斑块的中医药防治提供新思路和新方案。

基于中医血脉理论谈从脾论治糖尿病血管病变

糖尿病血管病变是糖尿病严重的慢性并发症之一,目前已成为糖尿病患者死亡和致残的主要原因,其巨额的医疗费用给家庭、社会带来沉重的经济负担。文章从血管与血脉的相关性出发,基于中医血脉理论,结合传统医学与现代医学观点,认为脾气虚,运化无力,气机不畅,脂浊不化,致痰浊、瘀血、热毒等病理产物壅滞血脉是糖尿病血管病变发生的重要原因,可累及多个靶器官。结合五脏一体观,从脾为四脏之长、脾与其他四脏的病变关系论述从脾论治糖尿病血管病变的理论依据以及古今医家从脾论治糖尿病血管病的临床思路,并将中西医思想融会贯通,突出从脾论治糖尿病血管病变的重要性。治疗上注重益气养阴、活血解毒、健脾化湿之法,为临床防治糖尿病血管病变提供新思路。

恶性肿瘤复合病机理论指导下温滋解毒法的构建

基于恶性肿瘤的复合病机,将正邪、阴阳和中气等理论与癌毒理论相整合,指出正虚邪盛为肿瘤的发病基础。阴阳俱损、气机郁滞、癌毒深伏为肿瘤的病机特点。认为阴阳俱损多起于脾肾,气机郁滞首先责之于脾胃,癌毒深伏常兼夹多种邪气。基于此提出以温滋解毒法为恶性肿瘤的基本治法。温滋解毒法是温法、滋法、解毒法三法并用或次第应用,共同发挥温滋并用,调和阴阳;行气解郁,调畅情志;消癌解毒,破兼夹之邪的功效。
