1Diagnostic efficacy of gadoxetic acid-enhanced MRI for hepatocellular carcinoma and dysplastic nodule显示文摘AIM:To evaluate the relationship between the signal intensity of hepatobiliary phase images on gadoxetic acid-enhanced magnetic resonance imaging(MRI)and histological grade.METHODS:Fifty-nine patients with 82 hepatocellular lesions were evaluated retrospectively.Hepatobiliary phase images on gadoxetic acid-enhanced MRI were classified into 3 groups:low,iso or high.Angiographyassisted computed tomography(CT)findings were also classified into 3 groups:CT during arterial portography,and CT hepatic arteriography:A:iso,iso or low;B:slightly low,iso or low;;and C:low,high.We correlated angiography-assisted CT,hepatobiliary phase findings during gadoxetic acid-enhanced MRI and histological grades.Furthermore,correlations between MRI findings and histological grade for each hemodynamic pattern were performed.Correlations among radiologicaland pathological findings were statistically evaluated using the chi-square test and Fisher's exact test.RESULTS:There was a significant correlation between histological grade and hemodynamic pattern(P<0.05).There was a significant correlation between histological grade and signal intensity in the hepatobiliary phase(P<0.05)in group A lesions.There was no significant correlation between histological grade and signal intensity in the hepatobiliary phase in group B or C lesions(P>0.05).CONCLUSION:Signal intensity in the hepatobiliary phase correlated with histological grade in the lesions that maintained portal blood flow,but did not correlate in lesions that showed decreased or defective portal blood flow.Kazuhiro Saito Ryota Nishio Toru Saguchi Soichi Akata Koichi Tokuuye Fuminori Moriyasu Katsutoshi Sugimoto Junichi Taira Toshitaka Nagao 2011World Journal of Gastroenterology2011,17,30:12

3Esophagus and regenerative medicine显示文摘In addition to squamous cell carcinoma,the incidence of Barrett's esophagus with high-grade dysplasia and esophageal adenocarcinoma is rapidly increasing worldwide.Unfortunately,the current standard of care for esophageal pathology involves resection of the affected tissue,sometimes involving radical esophagectomy.Without exception,these procedures are associated with a high morbidity,compromised quality of life,and unacceptable mortality rates.Regenerative medicine approaches to functional tissue replacement include the use of biological and synthetic scaffolds to promote tissue remodeling and growth.In the case of esophageal repair,extracellular matrix(ECM) scaffolds have proven to be effective for the reconstruction of small patch defects,anastomosis reinforcement,and the prevention of stricture formation after endomucosal resection(EMR).More so,esophageal cancer patients treated with ECM scaffolds have shown complete restoration of a normal,functional,and disease-free epithelium after EMR.These studies provide evidence that a regenerative medicine approach may enable aggressive resection of neoplastic tissue without the need for radical esophagectomy and its associated complications.Ricardo Londono Blair A Jobe Toshitaka Hoppo Stephen F Badylak 2012World Journal of Gastroenterology2012,18,47:4

7Cellular irinotecan resistance in colorectal cancer and overcoming irinotecan refractoriness through various combination trials including DNA methyltransferase inhibitors: a review显示文摘Treatment with pharmacological drugs for colorectal cancer(CRC)remains unsatisfactory.A major cause of failure in pharmacotherapy is the resistance of colon cancer cells to the drugs,creating an urgent issue.In this review,we summarize previous studies on the resistance of CRC cells to irinotecan and discuss possible reasons for refractoriness.Our review presents the following five major causes of irinotecan resistance in human CRC:(1)cellular irinotecan resistance is induced mainly through the increased expression of the drug efflux transporter,ABCG2;(2)cellular irinotecan resistance is also induced in association with a nuclear receptor,pregnane/steroid X receptor(PXR/SXR),which is enriched in the CYP3A4 gene enhancer region in CRC cells by exposing the cells to SN-38;(3)irinotecan-resistant cells possess either reduced DNA topoisomerase I(Top1)expression at both the mRNA and protein levels or Top1 missense mutations;(4)alterations in the tumor microenvironment lead to drug resistance through intercellular vesicle-mediated transmission of miRNAs;and(5)CRC stem cells are the most difficult targets to successfully treat CRC.In the clinical setting,CRC gradually develops resistance to initially effective irinotecan-based therapy.To solve this problem,several clinical trials,such as irinotecan plus cetuximab vs.cetuximab monotherapy,have been conducted.Another clinical trial on irinotecan plus guadecitabine,a DNA-methyltransferase inhibitor,has also been conducted.Shogo Ozawa Toshitaka Miura Jun Terashima Wataru Habano 2021Cancer Drug Resistance2021,4,4:2
8Diffusion-weighted imaging might be useful for reactive lymphoid hyperplasia diagnosis of the liver: A case report显示文摘BACKGROUND Reactive lymphoid hyperplasia(RLH)of the liver is a rare liver lesion.It is considered difficult to differentiate radiologically from hepatocellular carcinoma,metastatic liver tumor and other pathologies.CASE SUMMARY A 54-year-old woman presented to our hospital with RLH of the liver.The patient had a diagnosis of metastatic carcinoma of the liver from an unknown origin and subsequently underwent partial hepatectomy.However,histopathological analysis revealed RLH.The lesion showed perinodular enhancement in the arterial phase on contrast-enhanced computed tomography and magnetic resonance imaging.On diffusion-weighted imaging(DWI),we encountered linear hyperintensity along the portal tract consecutive to the liver lesion,which is a new characteristic radiologic finding.This finding corresponded to the lymphoid cell infiltration of the portal tract.Furthermore,there was strongly restricted diffusion on the apparent diffusion coefficient map.We used these characteristic radiologic findings to diagnose the lesion as a lymphoproliferative disease.CONCLUSION The linear hyperintensity consecutive to the liver lesion on DWI provided additional valuable diagnostic information.Taro Tanaka Kazuhiro Saito Daisuke Yunaiyama Jun Matsubayashi Yuichi Nagakawa Maki Tanigawa Toshitaka Nagao 2020World Journal of Clinical Cases2020,8,21:2
