ABSTRACT
Objective To investigate the changes in serum levels of angiopoietin-like protein 4(ANGPTL4)and ubiquitin carboxyl terminal hydrolase-1(UCH-L1),and CHA2DS2-VASc score in patients with non-valvular atrial fibrillation(NVAF)and acute cerebral infarction(ACI),and their diagnostic value.Methods A total of 162 NVAF patients treated in our hospital from Janu-ary 2021 to January 2023 were enrolled and divided into a combined group(45 cases)and a non-combined group(117 cases)according to having ACI or not.General clinical information,CHA2DS2-VASc scores,and serum levels of ANGPTL4 and UCH-L1 were collected and detected.Spearman correlation analysis was applied to evaluate the correlation of ANGPTL4,UCH-L1 and CHA2DS2-VASc score.Multivariate logistic regression analysis was performed to identify the in-fluencing factors of NVAF combined with ACI.ROC curve was plotted to evaluate the diagnostic value of serum ANGPTL4,UCH-L1,and CHA2DS2-VASc score for NVAF combined with ACI.Results The ANGPTL4 level was significantly lower,and the UCH-L1 level and CHA2DS2-VASc score were obviously higher in the combined group than the non-combined group(P＜0.05).In the patients with NVAF combined with ACI,serum ANGPTL4(r=-0.548,P＜0.05)and UCH-L1(r=0.400,P＜0.05)levels were negatively and positively correlated with CHA2DS2-VASc score,respectively.ANGPTL4,UCH-L1 and CHA2DS2-VASc were the risk fac-tors for ACI in NVAF patients(P＜0.05,P＜0.01).The AUC value of combined serum ANGPTL4 and UCH-L1 levels and CHA2DS2-VASc score for diagnosing NVAF complicated with ACI was 0.926(95％CI:0.874-0.961).Conclusion Combined detection of serum AUCH-L1 and NGPTL4 levels and CHA2DS2-VASc score can significantly improve the diagnostic value of NVAF patients with ACI.
ABSTRACT
Plexiform fibromyxoma (PF) of the stomach is a very rare mesenchymal tumor of the gastrointestinal tract. We report the first case of PF with 2 different growth patterns pathologically confirmed after surgical resection. The tumor was characterized microscopically as infiltrative; it demonstrated diffuse growth into the smooth muscle bundles of the muscularis propria and was also multinodular and plexiform within the myxoid stroma.Immunohistochemical analysis revealed that the tumor cells were positive or weakly positive for smooth muscle actin, vimentin, and H-caldesmon and negative for desmin, CD117, CD34, CK-20, Pan-CK, Dog1, S100, ER, PR, and CD10. No mutations of C-kit and platelet-derived growth factor receptor alpha were detected. No genetic disruption of glioma-associated oncogene homolog 1 was detected by fluorescence in situ hybridization. The final diagnosis of PF was mainly based on the morphological and immunohistochemical findings.
