ObjectiveTo investigate the effects of jatrorrhizine on endogenous metabolites and metabolic pathways in the mouse model of ulcerative colitis. MethodsThirty male C57BL/6J mice were randomly divided into the normal group， the model group， the low-dose and high-dose jatrorrhizine groups （0.04， 0.16 g·kg^-1）， and the mesalazine group （0.52 g·kg^-1）The mouse model of ulcerative colitis was established with 3% dextran sulfate sodium （DSS） and treated with different doses of jatrorrhizine by gavage. The changes in body weight， colon length， disease activity index （DAI）， and colonic histopathology were analyzed to evaluate the therapeutic effects of jatrorrhizine. UPLC-Q-TOF/MS was employed to determine the serum and fecal levels of metabolites in mice. Metabolomics methods were used to screen the differential metabolites， on the basis of which the potential therapeutic mechanism of jatrorrhizine on DSS-induced ulcerative colitis in mice was investigated. ResultsAfter intervention with jatrorrhizine， the model mice showed significantly decreased DAI（P<0.05，P<0.01）， recovered colon length，（P<0.05，P<0.01） and alleviated histopathology of the colon. The metabolomics study screened out 13 differential metabolites in the serum and 8 differential metabolites in the feces. The pathway enrichment analysis predicted three potential metabolic pathways： Biosynthesis of unsaturated fatty acids， phenylalanine， tyrosine and tryptophan biosynthesis， and phenylalanine metabolism. ConclusionJatrorrhizine may treat ulcerative colitis by regulating the biosynthesis and metabolism of amino acids and the synthesis of unsaturated fatty acids.

Objective:To investigate the relevant data on radiation dose in interventional radiodiagnosis and radiology of adults in Beijing and to provide a basis for establishing relevant diagnostic reference levels (DRLs) in this region.Methods:A total of 30 medical institutions in Beijing were surveyed, covering interventional radiodiagnosis and radiology surgeries for coronary artery, structural heart diseases, permanent cardiac pacemaker implantation, electrophysiological study and radiofrequency ablation, nervous systems, abdominal systems, and the blood vessels of the lower limbs. The primary parameters investigated included the air kerma area product ( PKA) and incident air kerma ( Ka, r). The 75 th percentiles of radiation dose were considered DRLs, which were analyzed at both the overall and individual medical institution levels. Results:A total of 3 331 cases of the abovementioned radiodiagnosis and radiology surgeries were collected. The DRLs (i.e., PKA and Ka, r) of various diagnostic examinations were 37.87 Gy·cm 2 and 509.00 mGy for coronary artery, 9.34 Gy·cm 2 and 48.00 mGy for electrophysiological study and radiofrequency ablation, 218.50 Gy·cm 2 and 901.70 mGy for nervous systems, 81.00 Gy·cm 2 and 302.20 mGy for the abdominal system, and 83.37 Gy·cm 2 and 214.69 mGy for the blood vessels of the lower limbs. In contrast, the DRLs (i.e., PKA and Ka, r) for interventional radiodiagnosis and radiology were determined at 135.00 Gy·cm 2 and 1 897.58 mGy for coronary artery, 26.91 Gy·cm 2 and 172.30 mGy for structural heart diseases, 27.77 Gy·cm 2 and 87.75 mGy for permanent cardiac pacemaker implantation, 34.46 Gy·cm 2 and 247.00 mGy for electrophysiological study and radiofrequency ablation, 214.36 Gy·cm 2 and 1 282.80 mGy for the nervous system, 196.64 Gy·cm 2 and 875.71 mGy for abdominal system, and 108.25 Gy·cm 2 and 523.25 mGy for the blood vessels of the lower limbs. Conclusions:The DRLs of radiation dose in interventional radiodiagnosis and radiology in Beijing were determined through a survey and statistic analysis. These findings suggest that for certain interventional procedures, the optimized radiation protection should be enhanced.

Objective:To investigate the influence of contrast-enhanced computed tomography(CECT)on dose calculation in magnetic resonance imaging(MRI)-guided online adaptive radiotherapy(oART)based on the electron density(ED)assignment method for rectal cancer.Methods:A retrospective analysis was conducted on the medical data of 15 patients with locally advanced rectal cancer at middle-low segments,who admitted to the Chinese PLA General Hospital between December 2023 and April 2025.All patients underwent both plain computed tomography(PCT)and CECT scans during location.The average HU and ED value of all organs that were extracted from PCT and CECT images in the treatment plan system were obtained,and the influences of contrast agent of intake on image characteristics of the structure of each organ(small intestine,femoral head,bladder)were analyzed.PCT was used as referred image to design reference plan(Pref).The synthetic CT(sCT)was simulated and generated on the basis of PCT and CECT,respectively.The beam flow field that was same with Pref was used to recalculate dose on sCT,and then,the online plan(PPCT)based on PCT,and the online plan(PCECT)based on CECT were obtained,respectively,which can simulate the online dose calculation of MRI-guided online adaptive radiotherapy(oART).The Pref was used as reference to compare dosimetric parameters for target region and organ at risk(OAR)through dose volume histogram(DVH)and planed evaluation indicators.Additionally,three dimension(3D)slicer software was used to perform γ analysis for the results of dose distribution,and explore the differences among PPCT,PCECT and Pref on dose distribution.Results:In terms of image characteristics,the HU values of soft-tissue organs(intestine,bladder,spinal cord,soft tissue)and planning target volume(PTV)in CECT were higher than those in PCT,and the differences of them were statistically significant(Zintestines=-2.188,Zbladder=-3.196,tspinal cord=-3.767,tsoft tissue=-10.083,tPTV=-4.693,P<0.05),while its influence was less on bone tissue.The statistical results of ED were consistent with those of HU.Regarding to dosimetric parameters,there was no statistically significant difference in target coverage rate between PPCT and Pref(P>0.05),and the D50%of the PPCT[(2724.25±19.91)cGy]was higher than that of the Pref[(2718.99±21.13)cGy],and the difference was statistically significant(t=-3.679,P=0.002).However,the target coverage rate of PCECT was 94.65(94.04,95.27)%,and the difference of that between PCECT and Pref was statistically significant(Z=-2.158,P=0.031).For OAR,the differences of Dmax value of the small intestine,and the V20 of the left femoral head between PPCT and Pref were significant(Z=-2.556,-2.529,P<0.05).The differences of the Dmax of small intestine,and the D50%of bladder between PCECT and Pref were significant(t=-4.821,2.171,P<0.05).The comparative γ passed rates of PPCT,PCECT and Pref under the standards of 3 mm/3%and 2 mm/2%were all above 95%,and the differences were not significant(P>0.05).Conclusions:The influence of CECT on dose calculation in MRI-guided oART based on ED assignment method for rectal cancer is relatively small,which can be directly used in the design of reference plan,but the maximum dose of radiation-sensitive organs such as the small intestine should be paid attention.
