Abstract

BACKGROUND: Pancreatic damage is a common digestive system disease with no specific drugs. Static magnetic field (SMF), the key component of magnetic resonance imaging (MRI), has demonstrated prominent effects in various disease models. PURPOSE: To study the effects of 0.1-9.4 T SMFs on pancreatic injury induced by alcohol, and acute pancreatitis (AP) induced by L-arginine (L-Arg). STUDY TYPE: Prospective, animal model. ANIMAL MODEL: Twelve healthy C57BL/6J male mice, 30 AP model male mice, and 30 alcohol-associated liver disease (AALD) model male mice. FIELD STRENGTH/SEQUENCE: 1.5-9.4 T SMFs for 12 hours and 0.1 T SMF for 72 hours. No imaging sequence was used. ASSESSMENT: Histological analysis on AALD mice pancreas was conducted. For L-Arg-induced AP mice, their body weight, food/water consumption, open field behavior, blood analysis, as well as histological analysis, inflammatory, oxidative stress of the pancreas were measured. In vitro cellular experiments were also conducted. STATISTICAL TESTS: Data are presented as means ± SD and analyzed using the two-tailed Student's t-test or one-way analysis of variance (ANOVA) test. P values <0.05 were considered statistically significant. RESULTS: 1.5-7 T SMFs significantly reduced alcohol-induced pancreatic damage, increasing the structurally intact acinar area from 51.5% to 78.3%, whereas the effect of 9.4 T SMF is not obvious. 0.1 T SMF can reduce the AP mice lethality, increase the structurally intact acinar area from 31.0% to 59.7%, associated with the reduced pancreatic inflammatory responses (78.1% reduction of F4/80 and 80.0% reduction of MPO), 20.0% decreased oxidative stress and 53.2% reduced pancreatic cell apoptosis. DATA CONCLUSION: High-field MRI may be safe for pancreatic-related diseases at the animal level. SMFs have a future potential to be developed as non-invasive and highly penetrating physical modalities for the treatment of pancreatic injury including AP. PLAIN LANGUAGE SUMMARY: This study aims to evaluate the safety and potential therapeutic effects of moderate- to high-intensity static magnetic fields (SMFs) on mice with pancreatic injury. Their findings revealed that SMFs between 1.5 and 7 Tesla (T) helped reduce alcohol-induced pancreatic damage, while a stronger 9.4 T showed no effect. Interestingly, for mice with L-arginine-induced acute pancreatitis, a weaker 0.1 T significantly increased the area of healthy acinar cells from 31.0% to 59.7%. These results not only suggest that MRI-related SMFs are safe for pancreatic diseases in animals, but also unravel the potential of SMFs as a future treatment option for pancreatic disorders. EVIDENCE LEVEL: N/A TECHNICAL EFFICACY: Stage 1.

摘要

背景:胰腺损伤是一种常见的消化系统疾病,目前尚无特效药物。静磁场(SMF)作为磁共振成像(MRI)的关键组成部分,已在多种疾病模型中显示出显著效果。 目的:研究0.1 - 9.4 T静磁场对酒精诱导的胰腺损伤以及L - 精氨酸(L - Arg)诱导的急性胰腺炎(AP)的影响。 研究类型:前瞻性动物模型研究。 动物模型:12只健康的C57BL/6J雄性小鼠、30只AP模型雄性小鼠和30只酒精性肝病(AALD)模型雄性小鼠。 场强/序列:1.5 - 9.4 T静磁场作用12小时,0.1 T静磁场作用72小时。未使用成像序列。 评估:对AALD小鼠胰腺进行组织学分析。对于L - Arg诱导的AP小鼠,测量其体重、食物/水摄入量、旷场行为、血液分析以及胰腺的组织学分析、炎症、氧化应激情况。还进行了体外细胞实验。 统计检验:数据以均值±标准差表示,采用双侧学生t检验或单因素方差分析(ANOVA)进行分析。P值<0.05被认为具有统计学意义。 结果:1.5 - 7 T静磁场显著减轻酒精诱导的胰腺损伤,使结构完整的腺泡面积从51.5%增加到78.3%,而9.4 T静磁场的效果不明显。0.1 T静磁场可降低AP小鼠的致死率,使结构完整的腺泡面积从31.0%增加到59.7%,同时胰腺炎症反应减轻(F4/80减少78.1%,MPO减少80.0%),氧化应激降低20.0%,胰腺细胞凋亡减少53.2%。 数据结论:在动物水平上,高场MRI对胰腺相关疾病可能是安全的。静磁场有潜力被开发为治疗包括AP在内的胰腺损伤的非侵入性、高穿透性物理治疗手段。 通俗易懂的总结:本研究旨在评估中高强度静磁场(SMF)对胰腺损伤小鼠的安全性和潜在治疗效果。他们的研究结果显示,1.5至7特斯拉(T)的静磁场有助于减轻酒精诱导的胰腺损伤,而更强的9.4 T则无效果。有趣的是,对于L - 精氨酸诱导的急性胰腺炎小鼠,较弱的0.1 T显著将健康腺泡细胞面积从31.0%增加到59.7%。这些结果不仅表明与MRI相关的静磁场对动物胰腺疾病是安全的,还揭示了静磁场作为未来胰腺疾病治疗选择的潜力。 证据水平:无 技术疗效:1级
