Cerebroprotective effect of Huanglian Jiedu decoction on amyloid protein precursor/presenilin-1 double transgenic mice

Huanglian Jiedu decoction （HLJDD） has been shown to improve cerebral blood flow, and reduce lipid peroxidation damage to the brain and its energy metabolism. The present study was designed to observe the cerebroprotective effect of HL.JDD on an Alzheimer＇s disease rodent model, presenilin-1/amyloid protein precursor double transgenic mice. HLJDD reduced serum interleukin-6 and interleukin-113 levels, decreased [3-amyloid precursor protein gene and senile plaque expression, resisted oxidation, and reduced free radical-induced injury, thereby improving the learning and memory of these mice. Moreover, HLJDD at 433 mg/kg per day exhibited better effects compared with that at 865 or 216 mg/kg per day, and donepezil hydrochloride at 30 mg/kg per day. Thus, these results suggest that HLJDD may have protective effects against Alzheimer＇s disease.

The active ingredients of Huanglian Jiedu Decoction in treating COVID- 19 based on network pharmacology, molecular docking and molecular dynamics simulation

Objective:To explore the active ingredients of Huanglian Jiedu Decoction(HLJD)for the treatment of COVID-19 and to further verify the combination mode.Methods:The TCMSP database was used to search for HLJD active ingredients and targets.COVID-19 targets were collected from GeneCards,DisGeNET and OMIM databases.Material-active-ingredients-targets(gene)network and targets protein-protein interaction network were constructed using Cytoscape 3.8.0 and the STRING database.GO functional enrichment analysis and KEGG pathway enrichment analysis of core targets were performed using R software.Cytoscape 3.8.0 was used to build“compound-targets-pathways”to predict HLJD mechanisms,and active ingredients were used as ligands to molecularly dock with SARS-CoV-23CL hydrolase,Spike glycoprotein and ACE2.The binding energy was calculated by molecular dynamics simulations and molecular mechanics Poisson-Boltzmann surface area method,and intermolecular interactions and the contribution of each residue to the binding free energy were analyzed.Results:Four medicinal materials,66 compounds and 219 targets were identified.It is found that the Protein-Protein Interaction core network contained 35 HLJD key targets proteins for COVID-19 treatment.705 GO functional enrichment entries(P<0.05)were produced;while KEGG pathway enrichment analysis identified 142 pathways(P<0.05)involving the Tumor Necrosis Factor signaling pathway and Interleukin-17 signaling pathway,etc.The binding energies of Kihadanin A,Palmidin A,Obacunone and Hispidone are much smaller than those of the currently reported clinical drugs with anti-SARS-CoV-2 drugs.The results of the binding energy indicate that van der Waals force is the main driving force for enzyme-substrate combination,whereas the electrostatic interaction and non-polar solvents contribute less.Conclusion:The“multi-component-multi-targets-multi-pathway”synergy of HLJD,which binds to SARSCoV-23CL hydrolase,Spike glycoprotein and ACE2,can act on targets Heat Shock Protein 90 Alpha Family Class A Member 1,Adrenoceptor Beta 2,Checkpoint Kinase 1,Peroxisome Proliferator-Activated Receptor Gamma and Mitogen-activated protein kinase 14 to regulate multiple signal pathways,and it may have a therapeutic effect on COVID-19.

Many studies have revealed that Chinese medicine has shown tremendous advantages on the treatment of sepsis. Our study aims to explore the effect of Huanglian jiedu decoction and Jiawei huanglian jiedu decoction on organ function in septic rats. Methods SD rats were randomly divided into 7 groups, sham-group, cecal ligation and puncture group （CLP, 18h/72h）, Jiawei huanglian jiedu decoction group （JW, 18h/72h）, Huanglian jiedu decoc-tion group （W, 18h/72h）. Except the Sham group, the rats in other groups received cecal ligation and puncture method to induce sepsis. CLP groups were intragastric administration with normal saline after CLP. Huanglian jiedu decoction and Jiawei huanglian jiedu decoction groups were intragastric administration with Huanglian jie-du decoction and Jiawei huanglian jiedu decoction in the same time points. Glutamic-pyruvic transaminase （ALT）, glutamic oxalacetic transaminase （AST）, total bilirubin （TBIL）, creatinine（Cr）, urea, creatine kinase-MB （CK-MB）, lactate dehydrogenase （LDH） were detected by biochemical analyzer.

Total lung capacity （TLC） and function residual capacity （FRC） were measured by buxco re-search system. The wet to dry weight ratio （W/D） was tested. Moreover, changes in tissue pathology were evaluat-ed using hematoxylin and eosin （H＆E） staining and electron microscope.

More-over, the level of TLC and FRC was significantly increased, and the level of SP-A, W/D was significantly de-creased. In addition, the level of CK-MB, IL-6, HMGB-1 and MCP-1 in serum was decreased. Inflammation fac-tors were positively correlated with lung function, and the cardiac function was positively correlated with the or-gan function, the differences were statistically significant. In addition, the histological alterations of myocardium, lung and intestine were attenuated after treatment with Huanglian jiedu decoction and Jiawei huanglian jiedu de-coction.

Effect of Huanglian Jiedu Decoction (黄连解毒汤) on Glucose Transporter 4 Expression in Adipose and Skeletal Muscle Tissues of Insulin Resistant Rats

Objective： To investigate the effects of Huanglian Jiedu Decoction （黄连解毒汤, HLJDD） on glucose transporter 4 （GLUT4） protein expressions in insulin-resistant murine target tissues. Methods： The experimental male Wistar rats were established into insulin resistant models by injecting streptozotocin （STZ 30 mg/kg） via caudal vein and feeding them with high fat high caloric diet, and randomly divided into the model group, the aspirin group and the HLJDD group. Besides, a normal group was set up for control. Changes of body weight （BW）, levels of serum fasting blood glucose （FBG）, serum fasting insulin （FINS） and oral glucose tolerance test （OGTT） were routinely determined. The expression of GLUT4 protein in adipose and skeletal muscle tissues before and after insulin stimulation was determined with Western blot. Results： In the HLJDD group after treatment, BW and FBG got decreased, OGTT improved, and the expression and translocation of GLUT4 protein elevated obviously, either before or after insulin stimulation, as compared with those in the model group, showing significant differences respectively. Conclusion： The mechanism of improving insulin resistance by HLJDD is probably associated with its effect in elevating GLUT4 protein expression and translocation in adipose and skeletal muscle tissues of insulin resistant rats.

Exploring the potential mechanism of Huanglian Jiedu Decoction against sepsis based on network pharmacology

Background Huanglian Jiedu Decoction(HJD) is a typical traditional Chinese medicine which exhibits diverse curative effects against different kinds of diseases because of its multi-components and multi-targets. It has been widely used for the treatment of sepsis. However, the underlying molecular mechanism is still unclear.Methods Network pharmacology was applied to analyze the potential active ingredients and molecular mechanism of HJD in the treatment of sepsis.Results As a result, we totally found 102 active ingredients and 221 corresponding targets. Among them, 117 were hit by the 1 837 targets associated with sepsis. Our further analysis demonstrated 57 drug and disease intersection targets. Based on Gene Ontology(GO) enrichment analysis, 2176 biological process terms, 84 molecular function terms and 28 cellular component terms were acquired. By performing Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment analysis, we acquired the dominating signaling pathways associated with sepsis. By constructing protein-protein interaction network of common targets, 11 hub genes were identified.Conclusions Taken together, our results indicated that HJD may protect against sepsis via a mechanism involving multiple targets and pathways.
