Infants exhibit diminished susceptibility to external infections， a phenomenon closely linked to the pervasive presence of the bifidobacterial community within their intestinal tract. Nonetheless， a significant knowledge gap remains concerning the distinct species of bifidobacteria initiating anti-infection immune responses during the early developmental stages. In this study， the impact of early intervention with Bifidobacterium bifidum (B. bifidum)， B. breve， and B. longum on neonatal rats infected with Salmonella enterica serovar Typhimurium (S. typhimurium) SL1344 were compared. The study encompasses various immunity levels， including gut immunity， central immunity (thymus)， peripheral immunity (spleen)， and brain immunity. Following Salmonella infection， significant alterations in neonatal rats were observed in growth and developmental levels， immune markers， cytokine levels， balance of T lymphocyte subpopulations， intestinal barrier function， and blood-brain barrier integrity. Compared with B. breve and B. longum， B. bifidum demonstrated more pronounced efficacy in regulating these physiological processes. By conducting multi-level analyses of gut microbiota， bifidobacterial community， colonic content metabolomics， and serum metabolomics， the significance of B. bifidum's role is underscored， and the immune-enhancing function of messenger metabolites is unveiled. Among these metabolites， γ-L-Glutamyl-L-glutamic acid and Orotic acid were found to be shared by all three species， while Hippuric acid and 1a，1b-dihomo Prostaglandin F2α were unique to B. bifidum， and DL-Arginine was specific to B. longum. Overall， this study has provided novel insights into the intervention and immunomodulation by Bifidobacterium in early-life infections， emphasizing the significant role of B. bifidum.

OBJECTIVES To establish a scoring system combining the ACEF score and the quantitative blood flow ratio(QFR) to improve the long-term risk prediction of patients undergoing percutaneous coronary intervention(PCI).METHODS In this population-based cohort study, a total of 46 features, including patient clinical and coronary lesion characteristics, were assessed for analysis through machine learning models. The ACEF-QFR scoring system was developed using 1263consecutive cases of CAD patients after PCI in PANDA Ⅲ trial database. The newly developed score was then validated on the other remaining 542 patients in the *** In both the Random Forest Model and the Deep Surv Model, age, renal function(creatinine), cardiac function(LVEF)and post-PCI coronary physiological index(QFR) were identified and confirmed to be significant predictive factors for 2-year adverse cardiac events. The ACEF-QFR score was constructed based on the developmental dataset and computed as age(years)/EF(%) + 1(if creatinine ≥ 2.0 mg/d L) + 1(if post-PCI QFR ≤ 0.92). The performance of the ACEF-QFR scoring system was preliminarily evaluated in the developmental dataset, and then further explored in the validation dataset. The ACEF-QFR score showed superior discrimination(C-statistic = 0.651;95% CI: 0.611-0.691, P < 0.05 versus post-PCI physiological index and other commonly used risk scores) and excellent calibration(Hosmer–Lemeshow χ^(2)= 7.070;P = 0.529) for predicting 2-year patient-oriented composite endpoint(POCE). The good prognostic value of the ACEF-QFR score was further validated by multivariable Cox regression and Kaplan–Meier analysis(adjusted HR = 1.89;95% CI: 1.18–3.04;log-rank P < 0.01) after stratified the patients into high-risk group and low-risk *** An improved scoring system combining clinical and coronary lesion-based functional variables(ACEF-QFR)was developed, and its ability for prognostic prediction in patients with PCI was further validated to be signi
