AIM： To explore the expression of phosphatase and tensin homolog deleted on chromosome ten （PTEN） in liver of athymic mice with hepatocellular carcinoma （HCC） and the effect of Fuzheng Jiedu Decoction （FJD）. METHODS： Forty eight male BALB/c athymic mice models were built by Bel-7402 with an indirect method. After 24 h of postoperation, the 48 athymic mice were distributed randomly into 4 groups： A, B, C, D, each group had 12 athymic mice. Group A were were treated by intragastric administration with FT207 （Tegafur） for 4 wk. Group B, C and D were treated by intragastric administration with FJD （complex prescription of Chinese crude drug） that had been delegated into 3 kinds of density as the low, middle, and high for 4 wk. At last, athymic mice were put to death, live time, volume of tumors, exponent of tumors and the tumor metastasis in livers were observed; and PTEN was detected in hepatic tissue, latero-cancer tissue and cancer tissue by immunohistochemistry. RESULTS： Four weeks later, the total survival rate in treatment group （A ＋ B ＋ C） was 50% and higher than the control group （0%） treated by FT207, （P 〈 0.01）. The survival rate in group A, B, C was higher than in group D, and except group A with D, there was significant differentces （Fisher＇s Exact Test P = 0.05 or 0.01）. And no differences were observed between the treatment groups and the control group in volume of tumors and exponent of tumors （P 〉 0.05）. Tumor metastasis in livers of the treatment group was less than the controls （Fisher＇s Exact Test, P = 0.021）. The result of immunohistochemistry showed that the intensity of PTEN in latero-cancer tissue was the highest, and then the hepatic tissue, the lowest was cancer tissue （Kruskal- Wallis test, X^2 = 60.67, P = 0.000）. It also showed that the intensity of PTEN in treatment groups （A, B, C） was higher than the control group （D） （F = 5.90, P = 0.002 in hepatic tissue and F = 15.99, P = 0.000 in latero-cancer tissue and X^2 = 26.08, P = 0.000 in cancer tissue）, and group B is the highest in the treatment groups （P 〈 0.05, r = 0.01. respectively）. However, there was no significant statistic difference between group A and group C （P 〉 0.05）. CONCLUSION： FJD can prolong the survival time and decrease tumor metastasis in livers of these experimental mice. Mechanisms of FJD healing HCC may partially be explained by enhancing the expression of PTEN in liver.

Discussion about the Treatment of Alzheimer's Disease with Yisui Fuyong Decoction Based on Synaptic Plasticity

For Alzheimer's disease(AD),the earliest symptom is memory loss,which runs throughout the disease.The mutual growth and decline of long-term potentiation(LTP)and long-term depression(LTD)in synaptic plasticity is the basic condition of learning and memory.In the early stage of AD,there is no significant change in synaptic plasticity,so the treatment should mainly focus on warming yang and replenishing qi.In the middle stage of AD,LTP is continuously damaged and reduced,and synaptic plasticity is destroyed,such as weakness of the spleen and stomach,causing stagnation of endogenous retention of phlegm in the brain,so the treatment should focus on enriching yin and tonifying yang,resolving phlegm to remove stagnation.In the late stage of AD,due to excessive deposition of amyloid and other metabolites,neurotoxins are produced and brain atrophy is aggravated,such as depression leading to stasis,phlegm and stasis binding together,long term of stasis turning to heat toxin,which invades the brain,excessive heat damages yin,then both yin and yang are damaged,finally,the brain collateral loses nutrition,so the treatment should focus on replenishing essence and reinforcing marrow,detoxifying and resolving stasis.Yisui Fuyong Decoction can replenish essence and reinforce marrow to nourish yin,warm yang and tonify qi to strengthen yang,combine phlegm resolving,stasis elimination and collateral vessels dredging,realizing the treatment effects in all three stages of synaptic plasticity.

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.

Objective To investigate and predict the molecular targets and mechanism of Huanglian Jiedu Decoction(黄连解毒汤,HLJDD)in the treatment of Corona Virus Disease 2019(COV-ID-19)through network pharmacology and molecular docking analysis.Methods The chemical constituents and action targets of HLJDD were retrieved on Tradi-tional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP),SymMap v2,Encyclopedia of Traditional Chinese Medicine(ETCM),a High-throughput Ex-periment-and Reference-guided Database of Traditional Chinese Medicine(HERB),and Tra-ditional Chinese Medicine Integrated Database(TCMID).UniProt and GeneCards were used to query the target genes that corresponding to the active compounds,and then a compound-target network was constructed using Cytoscape 3.7.2.Gene Ontology(GO)database was used to annotate GO functions.Kyoto Encyclopedia of Genes and Genomes(KEGG)was used to predict the possible mechanisms of active compounds.The Database for Annotation,Visu-alization and Integrated Discovery(DAVID)was used to analysis the tissue enrichment.The main active compounds in HLJDD are molecularly docked with their corresponding related targets.Results Seventy-six compounds were screened and 458 corresponding targets in the network were obtained.Gene annotation showed that the targets were involved mainly in 1953 biolo-gical processes.884 signaling pathways was enriched,involving signaling by interleukins,cy-tokine signaling in immune system,generic transcription pathway,and RNA polymerase II transcription.The targets mainly distributed in the lung,liver,and placenta,involving a vari-ety of immune cells,such as T cells and B cells.The molecular docking results showed that core compounds such as wogonin,berberine,and baicalein had high affinity with tumor nec-rosis factor(TNF),insulin(INS),and tumor protein 53(TP53).Conclusion The active compounds in HLJDD may have a therapeutic effect on COVID-19 through regulating multiple signal pathways by targeting genes such as vascular endothelial growth factor A(VEGFA),INS,interleukin-6(IL-6),TNF,caspase-3,TP53,and mitogen-activ-ated protein kinase 3(MAPK3).

Effect of Huanglian Jiedu Decoction on cardiac endoplasmic reticulum stress in spontaneously hypertensive rats

Huanglian Jiedu Decoction(HLJDD)is a quintessential prescription renowned for its heat-clearing and detoxifying properties.It is primarily prescribed to counteract the syndrome characterized by the excessive heat of the Sanjiao fire.Notably,the hyperactivity of liver fire is frequently linked with hypertension,where wind fire and wind toxicity emerge as pivotal pathogenic factors.This study aimed to investigate the impact of HLJDD on the endoplasmic reticulum in spontaneously hypertensive rats(SHR),further delving into the interplay between endoplasmic reticulum stress(ERS)and myocardial remodeling and damage.Fifty SHR rats were stratified randomly into five cohorts:model,low-dose HLJDD,medium-dose HLJDD,high-dose HLJDD,and captopril groups.For comparison,a set of Wistar-Kyoto(WKY)rats served as the baseline control group,with each group comprising 10 rats.While the model and control groups received equivalent volumes of normal saline via gavage,the other groups were administered the respective drug dosages through the same route daily for a span of 6 weeks.Upon the experiment’s conclusion,metrics such as the heart mass index(HWI)and left ventricular mass index(LVWI)were assessed.Cardiac tissue anomalies were identified using H&E staining,while ERS-related protein and mRNA expression levels were ascertained via Western blotting analysis and qPCR.Moreover,TUNEL staining was employed to detect cardiomyocyte apoptosis.The findings indicated that increasing HLJDD concentrations corresponded with escalated HWI and LVWI in rat hearts(P<0.05).There was a marked enhancement in myocardial structural integrity,accompanied by a notable reduction in collagen fibers.The mRNA and protein expressions of myocardial inositol-dependent enzyme 1α(IRE1α),X-box binding protein 1(XBP1),glycoregulatory protein 78(GRP78),and CCAAT enhancer binding protein homologous protein(CHOP)in the medium and high-dose groups saw significant declines(P<0.05).These effects mirrored those observed in the captopril group.The study underscored HLJDD’s efficacy in mitigating myocardial tissue damage in SHR.This therapeutic effect was potentially attributed to the downregulation of IRE1α,XBP1,GRP78,and CHOP,curbing excessive ERS,diminishing cardiomyocyte apoptosis,and thereby conferring cardioprotection.
