Objective To investigate the intervention effect of Xiao'er Zhixiao Pingchuan Granules(XEZXPCG)on ovalbumin(OVA)-induced airway remodeling in asthmatic mice and its potential mechanism by regulating macrophage migration inhibitory factor(MIF)and inhibiting the phosphoinositide 3-kinase(PI3K)/protein kinase B(Akt)signaling pathway.Methods A total of 96 SPF-grade male BALB/c mice were randomly divided into blank,model,XEZXPCG low/medium/high-dose groups(2.05,4.10,and 8.20 g/kg),adeno-associated virus(AAV)NC shRNA,AAV MIF shRNA(MIF gene silencing),and LY294002(PI3K/Akt inhibitor,1 mg/kg)groups(12 mice in each group).Asthma models were established through OVA sensitization and challenge.Airway resistance and the proportions of inflammatory cells(eosinophils and macrophages)in bronchoalveolar lavage fluid(BALF)were detected.Serum inflammatory factor(OVA-IgE,interleukin[IL]-1β,IL-6,tumor necrosis factor-alpha,and interferon-gamma)levels and BALF were quantified.Hematoxylin and eosin,Masson,and periodic acid-Schiff staining were used to evaluate airway wall thickness(Wat/Phm),smooth muscle area(Wam/Phm),collagen deposition,and goblet cell metaplasia.Western blotting,immunofluorescence,and real-time fluorescence-qPCR were used to detect MIF protein and mRNA expressions,as well as activation markers of the PI3K/Akt pathway and cell cycle-related proteins(including cyclin-dependant kinase 6[CDK6],Cyclin D1,Cyclin D3,and p21),in lung tissues.Results Compared to the model group,a XEZXPCG medium or high-dose significantly reduced airway resistance(P<0.05),improved the imbalance of eosinophil and macrophage proportions in BALF,and decreased inflammatory factor levels in serum and BALF(P<0.05).XEZXPCG medium or high-dose alleviated airway epithelial damage,goblet cell hyperplasia,and collagen fiber deposition,and reduced the Wat/Phm and Wam/Phm(P<0.05),with effects comparable to those of the AAV MIF shRNA and LY294002 groups.XEZXPCG medium and high-inhibited MIF protein/mRNA expression(P<0.05),downregulated Akt phosphorylation(P<0.05),upregulated p21 protein expression,and downregulated Cyclin D1,Cyclin D3,and CDK6 expressions(P<0.05).Conclusion XEZXPCG alleviates airway inflammation and improves airway remodeling in OVA-induced asthmatic mice by inhibiting MIF expression,downregulating the PI3K/Akt signaling pathway,and regulating cell cycle progression.XEZXPCG enhances airway remodeling through MIF-mediated PI3K/Akt pathway regulation.

Background and aims:Environmental pollutants,particularly organochlorine insecticides like endosulfan(ENDO),are increasingly linked to liver toxicity and related diseases.Despite its widespread historical use,the mechanisms underlying ENDO-induced liver damage remain poorly understood.This study aims to elucidate the cellular and molecular mechanisms of ENDO-induced hepatotoxicity.Methods:C57BL/6 mice were exposed to ENDO for two weeks.Single-cell RNA sequencing(scRNA-seq)was subsequently performed on mouse livers to explore ENDO-induced hepatotoxicity at the single-cell level.Differentially expressed genes(DEGs)across cell types and treatments were identified and then subjected to pathway enrichment to uncover key biological processes affected by ENDO.Transcription factor(TF)regulatory network,pseudotime trajectory,and cellular communication analysis were used to explore the molecular and cellular changes after ENDO exposure.Results:ENDO not only caused direct hepatocyte injury but also activated hepatic stellate cells and lymphocytes,triggering inflammatory responses with upregulation of multiple key chemokines and cytotoxic genes.Additionally,ENDO exposure led to the recruitment and activation of myeloid cells,contributing to the inflammatory milieu.An increase in intercellular communication and changes to the hepatic microenvironment,especially the interaction between activated hepatic stellate cells and CD8+T cells were observed,further implicating these processes in ENDO-induced liver damage.Conclusions:This study provides new insights into the cellular and molecular mechanisms underlying liver injury induced by organochlorine insecticides like ENDO.Key genes and pathways involved in ENDO-associated liver toxicity have been identified at a single-cell resolution.These findings suggest that altered cellular communications and inflammatory responses may play pivotal roles in the pathogenesis of ENDO-induced liver injury.

OBJECTIVE To explore the mechanism of Baihe Dihuang decoction in the treatment of Alzheimer's disease(AD) based on network pharmacology, molecular docking and animal experiment. METHODS TCMSP were used to predict the active components and targets of Baihe Dihuang decoction and disease-related targets were collected from GeneCards, OMIM and DRUGBANK databases, respectively. Target protein interactions were analyzed with STRING database and biological function and pathway were analyzed with Metascape database. Lastly relevant results were analyzed with Cytoscape 3.8.0. AutoDock vina software was used for molecular docking to analyze the binding energy of the active components and key targets of Baihe Dihuang decoction. PyMOL software were used to visualize the optimal docking results. ICR male mice were randomly divided into control group, model group, Rolipram group, low, medium and high dose group of Baihe Dihuang decoction. After 14 days of administration, the neurobehavioral scores of mice in each group were collected, and the expression of related proteins in brain tissue was detected, ELISA and Western blotting were used to detect the expression of the key protein cAMP, PKA, p-CREB and BDNF. At last, the adverse reaction of Baihe Dihuang decoction was observed by vomiting experiment. RESULTS A total of 13 active components and 39 key targets were collected from network pharmacology. The docking results showed that the first 10 core targets all performed well and their effects were closely related to PRKACA. Compared with the control group, the model group mice's recognition rate of new objects and the spontaneous alternation reaction rate were significantly reduced, the escape latency was significantly prolonged, and the target quadrant stay time, the number of crossing platforms were significantly reduced; cAMP, PKA, p-CREB and BDNF in the hippocampus of mice was significantly decreased. Baihe Dihuang decoction could reverse the behavior of AD mice and the expression of cAMP, PKA, p-CREB and BDNF. In the vomiting experiment, the anesthesia recovery time of the Rolipram group was significantly prolonged, while that of the Baihe Dihuang decoction group was not significantly affected. CONCLUSION The mechanism of Baihe Dihuang decoction in the treatment of AD may be related to its influence on cAMP-PKA and regulation of cAMP-PKA-CREB-BDNF signal pathway, and the adverse reactions are milder than those of clopramide.

Objective:To explore the efficacy and safety of different anti-platelet regimens in the treatment of high-risk non-disabling ischemic cerebrovascular events (HR-NICE) guided by point-of-care testing of CYP2C19 gene. Methods:A single-centre, prospective, randomised, open-label, and blinded endpoint design was uesd in the study. From July 2020 to January 2022, HR-NICE patients were enrolled in the Stroke Green Channel and Department of Neurology of Xuzhou Central Hospital, and all patients were scraped the buccal mucosa for screening for CYP2C19 loss-of-function allele carriers by point-of-care testing . Patients with intermediate metabolism were defined as those who carried 1 loss-of-function allele and patients with poor metabolism were those who carried 2 loss-of-function alleles. This study reduced the test turnaround time to 1 hour by using a fully automated medical polymerase chain reaction analyzer for a point-of-care test of CYP2C19 genotype. CYP2C19 loss-of-function allele carriers were divided according to the random number table method into the conventional treatment group (clopidogrel 75 mg, once a day), the ticagrelor group (ticagrelor 90 mg, twice a day) and the intensive dose group (clopidogrel 150 mg, once a day) separately combined with aspirin (100 mg, once a day) dual antiplatelet for 21 days. Baseline information, Acute Stroke Org 10172 Treatment Trial staging, 90-day modified Rankin Scale score, occurrence of adverse events and severe adverse events were collected for all the 3 groups. The primary efficacy outcome was new stroke within 90 days, and the primary safety outcome was severe or moderate bleeding within 90 days. Results:A total of 716 patients were included: 240 in the conventional treatment group, 240 in the ticagrelor group and 236 in the intensive dose group. There was no statistically significant difference between the 3 groups at baseline (all P>0.05). There were 26 cases (10.8%) with new stroke events in the conventional treatment group, 11 cases (4.6%) in the ticagrelor group and 4 cases (1.7%) in the intensive dose group, with statistically significant differences among the 3 groups (χ 2=19.28, P<0.05), and the differences between the conventional treatment group and the ticagrelor group (χ 2=6.59, P=0.010) and between the conventional treatment group and the intensive dose group (χ 2=16.83, P<0.001) were statistically significant, whereas the difference between the ticagrelor group and the intensive dose group was not statistically significant ( P>0.05). In the 3 groups, there was 1 case (0.4%) of severe bleeding in the conventional treatment group, 6 cases (2.5%) in the ticagrelor group and none in the intensive dose group, which showed statistically significant differences (χ 2=7.23, P<0.05), and there was statistically significant difference between the ticagrelor group and the intensive dose group ( P=0.030). Among the patients with intermediate CYP2C19 metabolism, there were 13 cases (13/158, 8.2%) with 90-day recurrent stroke in the conventional treatment group, 4 cases (4/153, 2.6%) in the ticagrelor group, and 0 case (0/159) in the intensive dose group, with statistically significant difference (χ 2=16.04, P<0.001), and the differences between the intensive dose group and the conventional treatment group were statistically significant (χ 2=13.64, P<0.001), whereas there was no statistically significant difference between the intensive dose group and the ticagrelor group ( P>0.05). In the patients with 90-day recurrent stroke in the intensive dose group, there was 0 case (0/159) with intermediate metabolism and 4 cases (4/77,5.2%) with poor metabolism, with statistically significant differences ( P=0.011), whereas there were no statistically significant differences in the conventional treatment group and the ticagrelor group ( P>0.05). Conclusions:Screening carriers of CYP2C19 loss-of-function alleles by point-of-care testing can quickly and precisely guide the treatment of patients with non-cardiogenic HR-NICE. An intensive clopidogrel dose of 150 mg, once a day combined with aspirin was effective in reducing stroke recurrence with less occurrence of any bleeding and adverse events, and patients with intermediate CYP2C19 metabolism may be the best population to benefit.
