OBJECTIVE To investigate the improvement effect and mechanism of modified Jinfeicao powder （MJCP） on cough-variant asthma （CVA） in rats.METHODS Network pharmacology was employed to identify the key targets and signaling pathways involved in the therapeutic action of MJCP against CVA. Rats were divided into normal control group， model group， positive control group （prednisone acetate， 0.9 mg/kg）， and MJCP low-， medium-， and high-dose groups （3.5， 7， 14 g/kg）， with six rats in each group. Except for the normal control group， CVA models were established in other groups. From day 14 of the experiment， rats in each group were administered corresponding drugs or normal saline intragastrically once daily for 14 consecutive days. After the final administration， cough frequency， serum levels of immune-inflammatory and oxidative stress-related indicators， pulmonary histopathological changes， and expression of pathway-related proteins were detected and observed.RESULTS Network pharmacology identified five key targets， including tumor necrosis factor-α （TNF-α）， interleukin-6（IL-6）， and protein kinase B（AKT）， as well as signaling pathways such as phosphatidylinositol 3-kinase （PI3K）/AKT/mammalian target of rapamycin （mTOR） and hypoxia-inducible factor-1α （HIF-1α）. Animal experimental results showed that， compared with the model group， cough frequency was significantly reduced in all treatment groups （ P ＜0.05）. Serum levels of immunoglobulin E （IgE）， IL-6， TNF-α， Src family of protein tyrosine kinase， epidermal growth factor receptor， and malondialdehyde （MDA） （except for IgE and MDA in the MJCP low-dose group）， mean pathological scores， the ratio of total airway wall area to basement membrane perimeter， and the expression levels of α -smooth muscle actin， Collagen-Ⅰ， phosphorylated PI3K， phosphorylated AKT （except in the MJCP low-dose group）， phosphorylated mTOR， and HIF-1α protein in lung tissues were all significantly decreased （ P ＜0.05）. Glutathione （except in the MJCP low-dose group） and superoxide dismutase levels in serum were significantly increased（ P ＜0.05）.CONCLUSIONS MJCP may alleviate airway inflammation， airway remodeling， and oxidative stress by regulating the PI3K/AKT/mTOR and HIF-1α signaling pathways， thereby exerting its improvement effects on CVA.

Alzheimer’s disease (AD) is a prevalent neurodegenerative condition characterized by progressive cognitive decline and memory loss. As the incidence of AD continues to rise annually, researchers have shown keen interest in the active components found in natural plants and their neuroprotective effects against AD. Quercetin, a flavonol widely present in fruits and vegetables, has multiple biological effects including anticancer, anti-inflammatory, and antioxidant. Oxidative stress plays a central role in the pathogenesis of AD, and the antioxidant properties of quercetin are essential for its neuroprotective function. Quercetin can modulate multiple signaling pathways related to AD, such as Nrf2-ARE, JNK, p38 MAPK, PON2, PI3K/Akt, and PKC, all of which are closely related to oxidative stress. Furthermore, quercetin is capable of inhibiting the aggregation of β‑amyloid protein (Aβ) and the phosphorylation of tau protein, as well as the activity of β‑secretase 1 and acetylcholinesterase, thus slowing down the progression of the disease.The review also provides insights into the pharmacokinetic properties of quercetin, including its absorption, metabolism, and excretion, as well as its bioavailability challenges and clinical applications. To improve the bioavailability and enhance the targeting of quercetin, the potential of quercetin nanomedicine delivery systems in the treatment of AD is also discussed. In summary, the multifaceted mechanisms of quercetin against AD provide a new perspective for drug development. However, translating these findings into clinical practice requires overcoming current limitations and ongoing research. In this way, its therapeutic potential in the treatment of AD can be fully utilized.

OBJECTIVE To investigate the in vitro activity of Chansu injection against SARS-CoV-2 infection and determine whether bufalin is the primary active component responsible for its efficacy.METHODS The half-maximal effective concentration(EC50)of Chansu injection and bufalin against SARS-CoV-2 infection was determined using the CellTiter-Glo cell viability assay.qPCR was performed to assess the effects of Chansu injection and bufalin on mRNA levels of SARS-CoV-2 NP protein,inflammatory factors,and interferons in virus-infected cells.A cell-cell membrane fusion model was established,and the impact of the drugs on membrane fusion between HEK-293T and HEK-293T-ACE2 cells was evaluated using a luciferase reporter gene assay.RESULTS Chansu injection exhibited anti-SARS-CoV-2 virus infection activity,with an EC50 of 85.56 ng·mL-1.Chansu injec-tion significantly reduced the mRNA levels of viral NP protein(P<0.05),IFN-λ2/3(P<0.05),ISG-15 and RIG-I(P<0.000 1)in SARS-CoV-2 infected Calu-3 cells,and the mRNA levels of inflammatory factors IL-6 and TNF-α were significantly reduced(P<0.000 1).The EC50 of bufalin in inhibiting SARS-CoV-2 virus-infected cells was 13.3 nmol·L-1,which might be the main active component of Chansu injection in resisting SARS-CoV-2 virus-infected cells.Chansu injection could significantly inhibit the cell membrane fusion mediated by the S protein of SARS-CoV-2 virus,thereby blocking the virus invasion.CONCLUSION Chansu injection demonstrates in vitro anti-SARS-CoV-2 activity by suppressing NP protein expression,reducing inflammatory cytokine lev-els,and blocking viral entry through membrane fusion inhibition.Bufalin is likely the key active component responsible for its anti-SARS-CoV-2 effects.

Objective To screen genes associated with poor prognosis of colorectal cancer(CRC)through bioinformatics analysis.Methods The gene expression profiles of GSE74602,GSE110223,GSE113513 and GSE141174 were obtained from Gene Expression Omnibus(GEO)database,including samples from 65 CRC tissues and 65 normal tissues.Differentially expressed genes(DEGs)between CRC tissues and normal tissues were screened out by GEO2R tool and Venn software,and the consistent genes were extracted from DEGs by Venn software.A protein-protein interaction(PPI)network was constructed by the STRING database to identify key genes,which were analyzed by Kaplan-Meier Plotter and GEPIA.Kyoto encyclopedia of genes and genomes(KEGG)pathway enrichment analysis was conducted on the 13 selected genes.Results There were 171 DEGs obtained from the four datasets,including 148 up-regulated genes and 23 down-regulated genes.Up-regulated DEGs were enriched in the redox processes,bicarbonate transport,digestion,ion trans-membrane transport,and one-carbon metabolism;and down-regulated DEGs were enriched in the positive regulation of cell proliferation.The survival curve analysis showed that 30 of the 87 genes were significantly associated with poor survival prognosis.GEPIA showed that 13 of the 30 genes were highly expressed in CRC tissues compared to normal tissues,among which MYC and FGFR3 markedly enriched in the CRC pathway.Conclusion This study identifies that MYC and FGFR3 are significantly up-regulated in CRC and closely associated with poor prognosis,suggesting that they may serve as potential prognostic markers and therapeutic targets for CRC patients.

Follicular lymphoma(FL)is a type of non-Hodgkin's lymphoma,and its treatment options face many challenges.This paper discusses the pathogenesis and treatment of FL based on the clear-turbid theory in traditional Chinese medicine(TCM)."The clear and the turbid being related,and the rise and fall of qi being disorderly"is the basic pathogenesis of FL.As the disease progres-ses,"evil qi being blocked inside,and turbid evil harming the clear"aggravates,and finally"evil qi is strong and the disease progres-ses,and evil poison is generated inside".Based on this theory,the method of raising the clear and lowering the turbid and the method of dispersing the clear and removing the turbid are proposed to treat FL.The emphasis of raising the clear and lowering the turbid is to take raising and lowering as the key,movement and stillness as the pivot,and to treat the middle jiao;the emphasis of dispersing the clear and removing the turbid is to clear the triple jiao,warm the yang and invigorate the qi,and harmonize the spleen and kidney.Ca-ses are attached to illustrate,providing new ideas for the TCM treatment of FL.
