Combined allergic rhinitis and asthma syndrome (CARAS) is one of the common chronic airway inflammatory diseases in children. With the development of epigenetics, research on CARAS has gradually extended from protein levels to molecular levels, such as transcription and post-transcriptional regulation. N6-methyladenosine (m6A) methylation and ferroptosis have emerged as promising research hotspots in recent years, playing crucial roles in tumors, growth and development, and allergic diseases. This paper aims to summarize the characteristics of m6A and ferroptosis, along with their roles in the onset and progression of CARAS in children, thereby providing new insights and strategies for the diagnosis and treatment of childhood CARAS.

OBJECTIVE: To investigate possible associations between physical function assessment scales, such as Short Physical Performance Battery (SPPB) and Berg Balance Scale (BBS), with all-cause mortality in acute decompensated heart failure (ADHF) patients. METHODS: A total of 108 ADHF patients were analyzed from October 2020 to October 2022, and followed up to May 2023. The association between baseline clinical characteristics and all-cause mortality was analyzed by univariate Cox regression analysis, while for SPPB and BBS, univariate Cox regression analysis was followed by receiver operating characteristic curves, in which the area under the curve represented their predictive accuracy for all-cause mortality. Incremental predictive values for both physical function assessments were measured by calculating net reclassification index and integrated discrimination improvement scores. Optimal cut-off value for BBS was then identified using restricted cubic spline plots, and survival differences below and above that cut-off were compared using Kaplan-Meier survival curves and the log-rank test. The clinical utility of BBS was measured using decision curve analysis. RESULTS: For baseline characteristics, age, female, blood urea nitrogen, as well as statins, angiotensin-converting enzyme inhibitors, angiotensin II receptor blockers, or angiotensin receptor-neprilysin inhibitors, were predictive for all-cause mortality for ADHF patients. With respect to SPPB and BBS, higher scores were associated with lower all-cause mortality rates for both assessments; similar area under the curves were measured for both (0.774 for SPPB and 0.776 for BBS). Furthermore, BBS ≤ 36.5 was associated with significantly higher mortality, which was still applicable even adjusting for confounding factors; BBS was also found to have great clinical utility under decision curve analysis. CONCLUSIONS BBS or SPPB could be used as tools to assess physical function in ageing ADHF patients, as well as prognosticate on all-cause mortality. Moreover, prioritizing the improvement of balance capabilities of ADHF patients in cardiac rehabilitation regimens could aid in lowering mortality risk.

This paper aimed to investigate the therapeutic effect and mechanism of action of the Yiqi Fumai Formula(YQFM), a kind of traditional Chinese medicine(TCM), on mice with experimental heart failure based on the "heart-gut axis" theory. Based on the network pharmacology integrated with the group collaboration algorithm, the active ingredients were screened, a "component-target-disease" network was constructed, and the potential pathways regulated by the formula were predicted and analyzed. Next, the model of experimental heart failure was established by intraperitoneal injection of adriamycin at a single high dose(15 mg·kg~(-1)) in BALB/c mice. After intraperitoneal injection of YQFM(lyophilized) at 7.90, 15.80, and 31.55 mg·d~(-1) for 7 d, the protective effects of the formula on cardiac function were evaluated using indicators such as ultrasonic electrocardiography and myocardial injury markers. Combined with inflammatory factors in the cardiac and colorectal tissue, as well as targeted assays, the relevant indicators of potential pathways were verified. Meanwhile, 16S rDNA sequencing was performed on mouse fecal samples using the Illumina platform to detect changes in gut flora and analyze differential metabolic pathways. The results show that the administration of injectable YQFM(lyophilized) for 7 d significantly increased the left ventricular end-systolic internal diameter, fractional shortening, and ejection fraction of cardiac tissue of mice with experimental heart failure(P<0.05). Moreover, markers of myocardial injury were significantly decreased(P<0.05), indicating improved cardiac function, along with significantly suppressed inflammatory responses in cardiac and intestinal tissue(P<0.05). Additionally, the species of causative organisms was decreased, and the homeostasis of gut flora was improved, involving a modulatory effect on PI3K-Akt signaling pathway-related inflammation in cardiac and colorectal tissue. In conclusion, YQFM can affect the "heart-gut axis" immunity through the homeostasis of the gut flora, thereby exerting a therapeutic effect on heart failure. This finding provides a reference for the combination of TCM and western medicine to prevent and treat heart failure based on the "heart-gut axis" theory.

OBJECTIVE: To investigate chronic hepatitis C virus (HCV) infection's effect on gestational liver function, pregnancy and delivery complications, and neonatal development. METHODS: A total of 157 HCV antibody-positive (anti-HCV[+]) and HCV RNA(+) patients (Group C) and 121 anti-HCV(+) and HCV RNA(-) patients (Group B) were included as study participants, while 142 anti-HCV(-) and HCV RNA(-) patients (Group A) were the control group. Data on biochemical indices during pregnancy, pregnancy complications, delivery-related information, and neonatal complications were also collected. RESULTS: Elevated alanine aminotransferase (ALT) rates in Group C during early, middle, and late pregnancy were 59.87%, 43.95%, and 42.04%, respectively-significantly higher than Groups B (26.45%, 15.70%, 10.74%) and A (23.94%, 19.01%, 6.34%) ( P < 0.05). Median ALT levels in Group C were significantly higher than in Groups A and B at all pregnancy stages ( P < 0.05). No significant differences were found in neonatal malformation rates across groups ( P > 0.05). However, neonatal jaundice incidence was significantly greater in Group C (75.16%) compared to Groups A (42.25%) and B (57.02%) ( χ ² = 33.552, P < 0.001). HCV RNA positivity during pregnancy was an independent risk factor for neonatal jaundice ( OR = 2.111, 95% CI 1.242-3.588, P = 0.006). CONCLUSIONS Chronic HCV infection can affect the liver function of pregnant women, but does not increase the pregnancy or delivery complication risks. HCV RNA(+) is an independent risk factor for neonatal jaundice.

Objective The study aims to investigate the impact of microRNA-874-3p(miR-874-3p)regulation of plakophilin 3(PKP3)on the malignant biological behavior of lung adenocarcinoma cells and its underlying mechanism.Methods Immunohistochemistry and immunocytochemistry were used to detect the expression of PKP3 in lung adenocarcinoma tissue microarray and lung adenocarcinoma cell line A549 cells respectively,and the relationship between PKP3 and clinicopathological features of lung adenocarcinoma patients was analyzed.Select lung adenocarcinoma cell line A549,the experiment was divided into A549 cell group(blank control group),miR-NC group(transfected with miR-NC)and miR-mimics group(transfected with miR-874-3p mimics),sh-NC group(control group transfected with PKP3 silencing plasmid),sh-PKP3 group(transfected with PKP3 silencing plasmid),miR+pcDNA-PKP3 group(transfected with miR-874-3P mimics+pcDNA-PKP3,rescue group)and miR+pcDNA-NC group(transfected with miR-874-3p mimics+pcDNA-NC).The proliferation,invasion,migration and apoptosis of cells in each group were detected.ENCORI database was used to predict the upstream gene of PKP3,and dual luciferase assay was used to detect the targeting relationship between miR-874-3p and PKP3.MAPK/mTOR pathway-related proteins were detected by Western blotting.Results The expression of PKP3 in lung adenocarcinoma tissue was significantly higher than that in adjacent tissues.The high expression of PKP3 was related to clinical stage,tumor size,and lymph node metastasis(P＜0.05).Compared with the human normal lung epithelial cells(BEAS-2B),the expression of PKP3 in A549 cells increased significantly,and the expression of miR-874-3p decreased(P＜0.05).Overexpression of miR-874-3p decreased the PKP3 expression level(P＜0.05).Compared with the control group,both overexpression of miR-874-3p and silenced PKP3 inhibited the cloning and invasion ability of A549 cells,caused cell cycle arrest,and decreased the expression levels of cyclin dependent kinase 4(CDK4),cyclin D1,cyclin E1 proteins in A549 cells(P＜0.05).The expressions of Bax protein and Caspase-3 protein were up-regulated(P＜0.05),and apoptosis increased.Overexpression of PKP3 could reverse the biological behavior of overexpression of miR-874-3p.Overexpression of miR-874-3p and silencing of PKP3 significantly decreased the expressions of P38 MAPK and mTOR phosphorylated proteins.Conclusion MiR-874-3p can negatively regulate PKP3 expression and inhibit the malignant biological behavior of A549 cells through MAPK/mTOR pathway.

Aim To predict and verify the potential mechanism of the compatibility of"ginseng-astragalus-pueraria"in protecting islet morphology and improving insulin resistance by using network pharmacology.Methods The active ingredients and targets of the horn medicine were obtained from three platforms:TC-MSP,TCMIP,and BATMAN.The targets of type 2 dia-betes mellitus(T2DM)were obtained from three plat-forms:TTD,OMIM,and disgeNET.The PPI network was constructed by using the STRING database and Cy-toscape 3.9.1;GO and KEGG analysis were per-formed;POCASA 1.1 was used to predict protein binding sites,and AutoDock Vina1.1.2 was used for docking and experimental verification.Results"Gin-seng-astragalus-pueraria"screened out 2 021 targets,of which 152 were closely related to T2DM,and 10 key genes and the AGE-RAGE signaling pathway were i-dentified.Molecular docking showed that quercetin had good binding to RAGE,INS,and PI3K.Experi-ments showed that the horn drug increased insulin binding rate and secretion index and reduced serum in-sulin level and insulin resistance index.These data benefited from"ginseng-astragalus-pueraria"reducing the expression of AGE-RAGE,activating PI3K-Akt,in-hibiting NF-κB,and reducing the expression of IL-6,IL-1β and TNF-α.Conclusion The study suggests that"ginseng-astragalus-pueraria"regulates the AGE-RAGE/PI3K-Akt/NF-κB signaling pathway,repairs damaged islet morphology,and improves insulin resist-ance.

Aim To investigate the intestinal protection and possible mechanism of magnolol(MG)in newborn rats with necrotizing enterocolitis(NEC).Methods The rats were randomly divided into control group(Ctrl group),model group(NEC group)and treatment group(MG group).The NEC model was induced by hypoxia,cold stimulation,deep formula milk and LPS intragastric administration in 7-day-old rats for four days.They were killed after five days of treatment with MG(20 mg·kg-1).HE staining was used to observe the intestinal pathological injury.Western blot was used to detect the expressions of IL-1 β,TNF-α,NL-RP3,ASC,caspase-1 and tight junction protein in the distal ileum of rats.Colon contents were collected for 16S rDNA sequencing to understand the gut microbio-ta.Results MG improved the body mass and intesti-nal injury of NEC neonatal rats.The expressions of in-testinal IL-1β,TNF-α,NLRP3,ASC and caspase-1 proteins were down-regulated,and the expressions of Claudin,Occludin and ZO-1 proteins were up-regula-ted.16S rDNA showed that MG increased the diversity of intestinal flora,and at the phylum level,MG in-creased the abundance of firmicutes and bacteroides in NEC model,and decreased the abundance of pro-teobacteria.At the genus level,MG treatment in-creased the abundance of Lactobacillus,unclassified_Muribaculaceae,Racteroides,but decreased the abun-dance of Escherichia_Shigella,Rodentibacter and Fuso-bacterium.Conclusion MG intervention can protect the intestinal tract of NEC rats by potentially improving barrier function,and regulating the intestinal microbiota through the NLRP3/ASC/caspase-1 signaling pathway.

Momordica antiviral protein 30 kD(MAP30)is a type Ⅰ ribosome-inactivating protein(RIP)with antibacterial,anti-HIV and antitumor activities but lacks the ability to target tumor cells.To in-crease its tumor-targeting ability,the arginine-glycine-aspartic(RGD)peptide and the epidermal growth factor receptor interference(EGFRi)peptide were fused with MAP30,which was named ELRL-MAP30.The efficiency of targeted therapy for triple-negative breast cancer(TNBC)MDA-MB-231 cells,which lack the expression of estrogen receptor(ER),Progesterone receptor(PgR)and human epidermal growth factor receptor-2(HER2),is limited.In this study,we focus on exploring the effect and mecha-nism of ELRL-MAP30 on TNBC MDA-MB-231 cells.First,we discovered that ELRL-MAP30 significant-ly inhibited the migration and invasion of MDA-MB-231 cells and induced MDA-MB-231 cell apoptosis.Moreover,ELRL-MAP30 treatment resulted in a significant increase in Bax expression and a decrease in Bcl-2 expression.Furthermore,ELRL-MAP30 triggered apoptosis via the Fak/EGFR/Erk and Ilk/Akt signaling pathways.In addition,recombinant ELRL-MAP30 can inhibit chicken embryonic angiogenesis,and also inhibit the tube formation ability of human umbilical vein endothelial cells(HUVECs),indica-ting its potential therapeutic effects on tumor angiogenesis.Collectively,these results indicate that ELRL-MAP30 has significant tumor-targeting properties in MDA-MB-231 cancer cells and reveals potential ther-apeutic effects on angiogenesis.These findings indicate the potential role of ELRL-MAP30 in the targeted treatment of the TNBC cell line MDA-MB-231.
