Acute pancreatitis(AP)is a common and severe digestive disease in dogs,characterized by a high recurrence rate and complications that significantly impact canine health.This study in-vestigates the mechanism by which adipose-derived stem cells(ADSCs)regulate the CHOP/Bcl-2 pathway to mitigate acute pancreatic injury in dogs.Twenty Beagle dogs were randomly divided in-to four groups:a Sham group,an AP model group,an ADSCs treatment group,and a conditioned medium(CM)treatment group.The AP model was established by injecting a mixed solution of trypsin and sodium taurocholate into the AP model group.The ADSCs treatment group received intravenous injections of ADSCs immediately following surgery,while the CM treatment group re-ceived conditioned medium preparations.Pancreatic tissue was collected 24 hours post-surgery,and changes in the CHOP/Bcl-2 pathway were assessed using histopathology,transmission electron microscopy,western blotting,fluorescence quantification,immunofluorescence,and TUNEL stai-ning.The results indicated that AP induced significant interstitial edema,hemorrhage,inflammato-ry cell infiltration,chromatin contraction,and endoplasmic reticulum swelling,the expression lev-els of GRP78 and CHOP were found to be elevated,whereas the expression of Bcl-2 was downreg-ulated.Additionally,the expression levels of BAX,JNK,Caspase-3,and Caspase-12 increased,leading to an increased rate of cell apoptosis.Such changes result in an elevated apoptosis rate and a further decrease in Bcl-2 expression.Both ADSCs and CM therapy were found to alleviate the path-ological damage in pancreatic tissue,resulting in downregulation of CHOP and apoptosis-related markers,upregulation of Bcl-2,and a reduction in the apoptosis rate.The results of this study sug-gest that ADSCs may mitigate acute pancreatic injury induced by trypsin and sodium taurocholate in AP dogs by modulating the CHOP/Bcl-2 pathway.Targeted modulation of the transcriptional activity of CHOP may offer novel therapeutic approaches for AP.

Medical imaging is an important auxiliary means of disease diagnosis. In the process of diagnosis, diseases are usually presented in a static way, which is one of the characteristics of imaging diagnosis. However, this static representation of diseases imposes certain limitations, which can, to some extent, lead to the loss of medical humanities. Therefore, it is very important for imaging diagnostic doctors to correctly use philosophical thinking to understand, analyze, and solve problems. The reinforcement of philosophical thinking in imaging diagnosis entails commitment to the "patient-centered" perspective in medicine as well as the integration of comprehensiveness, regularity, and proactivity. This not only effectively trains the diagnostic thinking of imaging diagnostic doctors but also improves their humanistic quality, thereby addressing the problems associated with these limitations. This allows the diagnosis to be both technically accurate and emotionally attuned.
