GC-MS raw data were imported into Masshunter quantitative software (Agilent, USA, version number: v10.0.707.0). All ion fragments were automatically identificated and integrated by using default parameters,besides, all intergration was checked manually. The metabolite concerntration of sample was calculated according to linear regression standard curve.MetaboLightsPublicGas Chromatography MS - alternating - high-polarity25 mg solid sample were accurately weighed into 2 mL grinding tube and add 500 µL water containing 0.5%phosphoric acid. The sample were froze and ground at 50 Hz for 3 min, repeated twice, followed by ultrasonic for 10 min and centrifugation at 4 oC and 13000 g for 15 min. Take 200 µL out the supernatant aqueous solution into a 1.5 mL centrifuge tube, then add 0.2 mL N-butanol solvent containing internal standard 2-ethylbutyric acid (10 μg/mL) for exaction. Finally,vortexl for 10 s, ultrasound at low temperature for 10 min, followed by centrifugation at 4 oC and 13000 g for 5 min and the supernatant were carefully transferred to sample vials for analysis.Effect of probiotics intervention on short chain fatty acids in irradiated mice.Fourth Military Medical University: Air Force Medical UniversityGuiqiang Zhouserumbrainfecesmass spectrometry assayCollect mouse feces, collect blood from the apex of the heart, and collect serum at 4 ℃ and 12000rpm/min.

Ltd. (Shanghai, China). Analyte compounds were separated with a HP-FFAP (30 m×0.25mm×0.25 µm) capillary column, using 99.999% helium as a carrier gas at a constant flow rate (1 mL/ min). The GC column temperature was programmed to hold at 80 oC and rise to 120 oC at a rate of 40 oC per minute, then rise to 180 oC at a rate of 10 oC per minute, finally rise to 200 oC at a rate of 20 oC per minute hold at temperature of 220 oC for 3 min.

The content of short-chain fatty acids was determined by High Performance Liquid Chromatography-mass spectrum. Further investigate the effects of ionizing radiation on the levels of short-chain fatty acids in the gut brain axis of mice, as well as the therapeutic effects of probiotics on radiation exposed mice.2026-09-282026-09-21MTBLS15754
