Background Following on from an earlier study published in 2008 about left pulmonary artery(LPA)flow measured on serial echocardiography being strongly prognostic in left-sided congenital diaphragmatic hernia(CDH)and the ratio of LPA to right pulmonary artery(RPA)diameters being a simple and reliable indicator for commencing nitric oxide(NO)therapy,the ratio of LPA:RPA diameters(PA ratio orPAR)was hypothesized to possibly reflect cardiopulmonary stresses accompanying CDH *** Subjects with isolated left-sided CDH treated between 2007 and 2020 at a single pediatric surgical center were recruited and classified according to *** obtained retrospectively for subject demographics,clinical course,LPA/RPA diameters,and PAR were compared between survivors and *** value of PAR for optimizing the prognostic value of PA diameter data in CDH were analyzed with receiver operating characteristic(ROC)curve *** Of 65 subjects,there were 54 survivors(82.3%)and 11 non-survivors(17.7%);7 of 11 non-survivors died before surgical repair could be *** PAR for survivors(0.851±0.152)was significantly higher than for non-survivors(0.672±0.108)(p=0.0003).Mean PAR for non-survivors was not affected by surgical *** of survivors were:LPA≥2 mm(n=52 of 54;mean PAR=0.866±0.146)and RPA≥3mm(n=46 of 54;mean PAR=0.857±0.152).Non-survivors with similar LPA and RPA diameters to survivors had significantly lower mean *** curve cut-off for PAR was *** with high PAR(≥0.762)required high-frequency oscillatory ventilation/NO less than subjects with low PAR(<0.762)(p=0.0244 and p=0.0485,respectively)and subjects with high PAR stabilized significantly earlier than subjects with low PAR(1.71±0.68 days vs 3.20±0.87 days)(p<0.0001).Conclusions PAR would appear to be strongly correlated with clinical outcome in CDH and be useful for planning management of cardiopulmonary instability in CDH.

Inhibiting the death receptor 3(DR3)signaling pathway in group 3 innate lymphoid cells(ILC3s)presents a promising approach for promoting mucosal repair in individuals with ulcerative colitis(UC).Paeoniflorin,a prominent component of Paeonia lactiflora Pall.,has demonstrated the ability to restore barrier function in UC mice,but the precise mechanism remains *** this study,we aimed to delve into whether paeoniflorin may promote intestinal mucosal repair in chronic colitis by inhibiting DR3 signaling in ILC3s.C57BL/6 mice were subjected to random allocation into 7 distinct groups,namely the control group,the 2%dextran sodium sulfate(DSS)group,the paeoniflorin groups(25,50,and 100 mg/kg),the anti-tumor necrosis factor-like ligand 1A(anti-TL1A)antibody group,and the IgG *** detected the expression of DR3 signaling pathway proteins and the proportion of ILC3s in the mouse colon using Western blot and flow cytometry,***,DR3-overexpressing MNK-3 cells and 2%DSS-induced Rag1^(-/-)mice were used for *** results showed that paeoniflorin alleviated DSS-induced chronic colitis and repaired the intestinal mucosal ***,paeoniflorin inhibited the DR3 signaling pathway in ILC3s and regulated the content of cytokines(interleukin-17A,granulocyte-macrophage colony stimulating factor,and interleukin-22).Alternatively,paeoniflorin directly inhibited the DR3 signaling pathway in ILC3s to repair mucosal damage independently of the adaptive immune *** additionally confirmed that paeoniflorin-conditioned medium(CM)restored the expression of tight junctions in Caco-2 cells via *** conclusion,paeoniflorin ameliorates chronic colitis by enhancing the intestinal barrier in an ILC3-dependent manner,and its mechanism is associated with the inhibition of the DR3 signaling pathway.
