Synergistic effects of three traditional herbs green tea,mulberry leaf and corn silk on glucose uptake level of L6 myoblasts and the hypoglycemic mechanism

Background:Green tea,mulberry leaf and corn silk are traditional herbs used in the prevention and treatment of diabetes in China for a long time,but their synergistic hypoglycemic effects and mechanisms remain unclear.Methods:The effective components of green tea,mulberry leaf and corn silk were extracted and enriched.Mixture design of experiments was used to study the influences of different combinations on the cell viability and glucose uptake level of L6 myoblasts,so as to determine the optimal synergistic hypoglycemic combination.The possible hypoglycemic mechanism of the optimal synergistic combination was explored by cytotoxicity assay,glucose uptake assay,and western blot.Results:Three polyphenol enrichment fractions of the herbs,30%ethanol elution fraction of green tea(GT),50%ethanol elution fraction of mulberry leaf(ML)and 60%ethanol elution fraction of corn silk(CS)were obtained.The antioxidant activities of GT-30%,ML-50%and CS-60%were superior to those of crude extracts,and showed strong potential inα-amylase andα-glucosidase inhibition activities.The optimal synergistic combination of crude extracts G7(crude extract of green tea:crude extract of mulberry leaf:crude extract of corn silk=1:5:3),polyphenol enrichment fractions R3(GT-30%:ML-50%:CS-60%=1:7:1)and monomers X2(epigallocatechin gallate:morusin:formononetin=3:1:2)were selected,respectively.G7,R3,and X2 showed promoting effects on the cell viability and glucose uptake of L6 myoblasts within the detected concentration range.In addition,G7,R3,and X2 could increase the expression levels of p-PI3K/PI3K and p-Akt/Akt in L6 myoblasts,and promote the translocation of Glut4,but G7 and R3 showed more significant effects.Conclusion:The synergistic hypoglycemic effects of green tea,mulberry leaf and corn silk had the characteristics of multiple-components and multiple-targets with p-PI3K/PI3K,p-Akt/Akt and the translocation of Glut4 signal pathways involved.The three traditional herbs might have the potential to be combined used for the prevention and treatment of diabetes based on the synergistic hypoglycemic effects.

Research progress of Yinchenhao Decoction in the treatment of non-alcoholic fatty liver disease

Non-alcoholic fatty liver disease(NAFLD)is one of the most common chronic liver diseases worldwide.Non-alcoholic steatohepatitis(NASH)is the most serious type and a turning point in the progression of NAFLD.If not treated actively,NASH will progress to irreversible liver damage such as cirrhosis and hepatocellular carcinoma.At present,there are no specific therapeutic drugs in western medicine.The treatment methods are mainly to improve lifestyle and exercise therapy,to alleviate the symptoms of discomfort,delay the progress of the disease,and improve the quality of life.However,the effect is often not ideal,prone to recurrence,and compliance is relatively poor.Dramatically,traditional Chinese medicine has certain advantages in the treatment of NAFLD.Modern research has confirmed that Yinchenhao Decoction has a good effect on liver-protective and choleretic action and improving liver function.It has significant curative effect on various liver and gallbladder diseases such as acute liver injury and alcoholic liver disease.This article summarized the clinical and basic research of Yinchenhao Decoction in the treatment of NAFLD.We found that Yinchenhao Decoction can enhance the efficiency of NAFLD and improve symptoms such as dizziness,liver pain,hepatosplenomegaly and indigestion.The mechanisms may be related to that Yinchenhao decoction improves the disorder of glucose and lipid metabolism,inflammatory state and liver function.

Analysis on the rules of prescriptions for ischemic stroke based on the traditional Chinese medicine inheritance auxiliary system

In China,traditional Chinese medicine is widely used in the treatment of ischemic stroke,but its prescription rules needs to be further studied.This paper uses the traditional Chinese medicine inheritance auxiliary system(a software)to analyze the composition rules of a large number of prescriptions for the treatment of ischemic stroke,and discusses the clinical rationality of the new prescriptions.We found that the prescriptions for the treatment of ischemic stroke are mainly composed by herbs for promoting blood circulation and removing blood stasis,dredging collaterals and tonifying deficiency,and some of the new prescriptions are also in line with this characteristic.This paper can provide reference for clinical prescription in the treatment of ischemic stroke and the development of related new drugs.

Analysis of prescription rules in the treatment of diabetic heart disease based on traditional Chinese medicine inheritance support system

Diabetes is a common clinical disease and has many complications,among which diabetic heart disease is the leading cause of death in diabetic patients.This article collected the prescriptions for the treatment of diabetic heart disease,and used the traditional Chinese medicine inheritance support system to explore the prescription formulation rules.Finally,we included 43 prescriptions for analysis.We found that the rules of formulas for treating diabetic heart disease are complex,but Chinese medicines in these formulas are mainly with the effects of nourishing Qi,nourishing Yin and activating blood circulation.At the same time,we obtained 3 new prescriptions and discussed the clinical rationality of the new prescriptions.The purpose of this article is to provide reference for clinical prescription in the treatment of diabetic heart disease and the development of related new drugs.

A meta-analysis of Banxia Xiexin decoction versus omeprazole in the treatment of gastroesophageal reflux disease

Objective:To investigate the clinical efficacy and safety of Banxia Xiexin decoction and omeprazole in the treatment of gastroesophageal reflux disease(GERD).Methods:EMbase,Cochrane,PubMed,CNKI,Wan Fang and VIP database were searched from inception to November 2018 according to the search strategy.Eligible randomized controlled clinical trials related to the efficacy of omeprazole compared with Banxia Xiexin decoction in the treatment of GERD were included according to the inclusion and exclusion criteria.Total effective rate,pathological improvement rate,total symptom score,acid reflux symptoms,heartburn symptoms,improvement of post-sternal pain symptoms,and incidence of adverse reactions were evaluated.Data analysis was performed with RevMan5.3 software provided by Cochrane Collaboration.Results:A total of 15 studies were enrolled,including 1,532 patients.Meta-analysis results showed that the total effective rate of Banxia Xiexinfang was higher than that of omeprazole in the treatment of GERD(odds ratio(OR)=3.99,95%confidence intervals(CI)(2.58,6.15),P<0.00001).Pathological improvement under endoscopy was not obvious(OR=1.98,95%CI(0.94,4.19),P=0.07)between the two groups.The total symptom score improved significantly,indicating that Banxia Xiexin decoction has an objective advantage over omeprazole in the treatment of GERD(standardised mean difference(SMD)=?2.56,95%CI(?3.86,?1.26),P=0.0001),The incidence of adverse reactions in patients treated with Banxia Xiexin decoction is lower than omeprazole group(OR=0.09,95%CI(0.02,0.39),P=0.001].In addition,total effective rate of Banxia Xiexin decoction combined with omeprazole was higher than omeprazole alone(OR=6.31,95%CI(2.86,13.92),P<0.00001).Conclusion:Banxia Xiexin decoction is superior to omeprazole in total effective rate,total symptom score and adverse reaction rate in the treatment of GERD.The clinical efficacy of Banxia Xiexin decoction combined with omeprazole is better than that of omeprazole alone.However,due to the low quality of the included literatures,large-scale and high-quality RCTs are still needed for further confirmation.
