| 2 | Coronary spasm: It's common, but it's still unsolved显示文摘Coronary spasm is caused by a transient coronary nar -rowing due to the constriction of epicardial coronary artery, which leads to myocardial ischemia. More than 50 years have passed since the first recognition of coronary spasm, and many findings on coronary spasm have been reported. Coronary spasm has been considered as having pivotal roles in the cause of not only rest angina but also exertional angina, acute coronary syndrome, and heart failure. In addition, several new findings of the mechanism of coronary spasm have emerged recently. The diagnosis based mainly on coronary angiography and spasm provo-cation test and the mainstream treatment with a focus on a calcium-channel blocker have been established. At a glance, coronary spasm or vasospastic angina(VSA) has become a common disease. On the contrary, there are several uncertain or unsolved problems regarding coronary spasm, including the presence of medically refractory coronary spasm(intractable VSA), or an appropriate use of implantable cardioverter defibrillator in patients with cardiac arrest who have been confirmed as having coronary spasm. This editorial focused on coronary spasm, including recent topics and unsolved problems. | Hiroki Teragawa Chikage Oshita Tomohiro Ueda | 2018 | World Journal of Cardiology2018，10，11： | 7 |
| 3 | Partially hydrolyzed guar gum attenuates non-alcoholic fatty liver disease in mice through the gut-liver axis显示文摘BACKGROUND The gut-liver axis has attracted much interest in the context of chronic liver disease pathogenesis.Prebiotics such as dietary fibers were shown to attenuate non-alcoholic fatty liver disease(NAFLD)by modulating gut microbiota.Partially hydrolyzed guar gum(PHGG),a water-soluble dietary fiber,has been reported to alleviate the symptoms of various intestinal diseases and metabolic syndromes.However,its effects on NAFLD remain to be fully elucidated.To determine whether treatment with PHGG attenuates NAFLD development in mice through the gut-liver axis.METHODS Seven-week-old male C57BL/6J mice with increased intestinal permeability were fed a control or atherogenic(Ath)diet(a mouse model of NAFLD)for 8 wk,with or without 5%PHGG.Increased intestinal permeability was induced through chronic intermittent administration of low-dose dextran sulfate sodium.Body weight,liver weight,macroscopic findings in the liver,blood biochemistry[aspartate aminotransferase(AST)and alanine aminotransferase(ALT),total cholesterol,triglyceride,free fatty acids,and glucose levels],liver histology,myeloperoxidase activity in liver tissue,mRNA expression in the liver and intestine,serum endotoxin levels in the portal vein,intestinal permeability,and microbiota and short-chain fatty acid(SCFA)profiles in the cecal samples were investigated.RESULTS Mice with increased intestinal permeability subjected to the Ath diet showed significantly increased serum AST and ALT levels,liver fat accumulation,liver inflammatory(tumor necrosis factor-αand monocyte chemotactic protein-1)and fibrogenic(collagen 1a1 andαsmooth muscle actin)marker levels,and liver myeloperoxidase activity,which were significantly attenuated by PHGG treatment.Furthermore,the Ath diet combined with increased intestinal permeability resulted in elevated portal endotoxin levels and activated toll-like receptor(TLR)4 and TLR9 expression,confirming that intestinal permeability was significantly elevated,as observed by evaluating the lumen-to-blood clearance of fluorescein isothiocyanate-conjugated dextran.PHGG treatment did not affect fatty acid metabolism in the liver.However,it decreased lipopolysaccharide signaling through the gut-liver axis.In addition,it significantly increased the abundance of cecal Bacteroides and Clostridium subcluster XIVa.Treatment with PHGG markedly increased the levels of SCFAs,particularly,butyric acid,acetic acid,propionic acid,and formic acid,in the cecal samples.CONCLUSION PHGG partially prevented NAFLD development in mice through the gut-liver axis by modulating microbiota and downstream SCFA profiles. | Shun Takayama Kazuhiro Katada Tomohisa Takagi Takaya Iida Tomohiro Ueda Katsura Mizushima Yasuki Higashimura Mayuko Morita Tetsuya Okayama Kazuhiro Kamada Kazuhiko Uchiyama Osamu Handa Takeshi Ishikawa Zenta Yasukawa Tsutomu Okubo Yoshito Itoh Yuji Naito | 2021 | World Journal of Gastroenterology2021，27，18： | 4 |
| 4 | Serum Mac-2 binding protein is a novel biomarker for chronic pancreatitis显示文摘AIM: To determine the efficacy of Mac-2 binding protein(Mac-2bp) for diagnosis of chronic pancreatitis.METHODS: Fifty-nine healthy volunteers(HV), 162 patients with chronic pancreatitis(CP), and 94 patients with pancreatic ductal adenocarcinoma(PDAC) were enrolled in this study. We measured serum Mac-2bp using our developed enzyme-linked immunosorbent assay kit. Additional biochemical variables were measured using an automated analyzer(including aminotransferase, alanine aminotransferase, γ-glutamyltransferase, alkaline phosphatase, triglyceride, C-reactive protein, and amylase levels) or chemiluminescent enzyme immunoassay(carbohydrate antigen 19-9 and carcinoembryonic antigen). The ability of Mac-2bp to predict CP diagnosis accurately was assessed using receiver operating characteristic(ROC) analyses.RESULTS: Serum Mac-2bp levels were significantly increased in CP patients compared to HV(P < 0.0001) and PDAC patients(P < 0.0001). Area under the ROC curve values of Mac-2bp for the discrimination of CP from HV and PDAC were 0.727 and 0.784, respectively. Multivariate analyses demonstrated that serum Mac-2bp levels were independent determinants for CP diagnosis from HV and PDAC patients. Immunohistological staining showed that Mac-2bp was expressed faintly in the pancreas tissues of both CP and PDAC patients. Serum aspartate aminotransferase, alanine aminotransferase, γ-glutamyltransferase, alkaline phosphatase, and triglyceride levels were significantly higher in patients with CP or PDAC. Serum Mac-2bp levels were highly correlated with protein levels of alanine aminotransferase, γ-glutamyltransferase, and C-reactive protein, but not amylase, suggesting that the damaged liver produces Mac-2bp. CONCLUSION: Measurement of serum Mac-2bp may be a novel and useful biomarker for CP diagnosis as well as liver fibrosis in the general population. | Tomohiro Maekawa Yoshihiro Kamada Yusuke Ebisutani Makiko Ueda Tomoki Hata Koichi Kawamoto Shinji Takamatsu Kayo Mizutani Mayuka Shimomura Tomoaki Sobajima Hironobu Fujii Kotarosumitomo Nakayama Kimihiro Nishino Makoto Yamada Takashi Kumada Toshifumi Ito Hidetoshi Eguchi Hiroaki Nagano Eiji Miyoshi | 2016 | World Journal of Gastroenterology2016，22，17： | 3 |
| 5 | Case of angina pectoris at rest and during effort due to coronary spasm and myocardial bridging显示文摘We present a case of a 71-year-old male who hadchest symptoms at rest and during effort. He had felt chest oppression during effort for 1 year,and his chest symptoms had recently worsened. One month before admission he felt chest squeezing at rest in the early morning. He presented at our institution to evaluate his chest symptoms. Electrocardiography and echocardiography failed to show any specific changes. Because of the possibility that his chest symptoms were due to myocardial ischemia,he was admitted to our institution for coronary angiography(CAG). An initial CAG showed mild atherosclerotic changes in the proximal segment of the left anterior descending coronary artery(LAD) and mid-segment of the left circumflex coronary artery. Subsequent spasm provocation testing using acetylcholine revealed a bilateral coronary vasospasm,which was relieved after the intracoronary infusion of nitroglycerin. Finally,a CAG showed myocardial bridging(MB) of the mid-distal segments of the LAD. Fractional flow reserve using the intravenous administration of adenosine triphosphate was positive at 0.77,which jumped up to 0.90 through the myocardial bridging segments when the pressure wire was pulled back. Thus,coronary vasospasm and MB might have contributed to his chest symptoms at rest and during effort. Interventional cardiologists should consider the presence of MB as a potential cause of myocardial ischemia. | Hiroki Teragawa Yuichi Fujii Tomohiro Ueda Daiki Murata Shuichi Nomura | 2015 | World Journal of Cardiology2015，7，6： | 3 |

| 12 | Increased frequency of angina attacks caused by switching a brand-name vasodilator to a generic vasodilator in patients with vasospastic angina:Two case reports显示文摘It is well known that calcium channel blockers(CCBs) are the first line of therapy for vasospastic angina(VSA). Here, we report two cases of VSA with an increase in the frequency of angina attacks after switching from a brand-name to a generic CCB. In both cases, angina recurred upon switching from a brand-name CCB to a generic CCB during follow-up. The patients' condition improved upon switching back to the original CCB. Both cases involved a high severity of VSA, based on the results of spasm provocation testing. These findings suggest that, in some patients with severe VSA, the frequency of angina attacks increases when switching from a brand-name CCB to a generic CCB. Cardiologists should consider this factor when prescribing drugs for angina. | Remi Goto-Semba Yuichi Fujii Tomohiro Ueda Chikage Oshita Hiroki Teragawa | 2018 | World Journal of Cardiology2018，10，3： | 1 |
| 13 | Importance of a second spasm provocation test:Four cases with an initial negative spasm provocation test显示文摘The spasm provocation test(SPT) is an important test in the diagnosis of vasospastic angina(VSA). In many cases, this test is performed as the gold standard test, and VSA is considered not present if the SPT is negative. However, some patients continue to experience chest symptoms despite a negative SPT. In this study, we report four cases in which SPT was repeated to evaluate chest symptoms despite the negative results of the first SPT. Two men in their 70 s, one woman in her 60 s, and one woman in her 70 s, all with chest symptoms, underwent a second SPT at 4, 3, 2, and 3 years, respectively, after the first SPT, which was negative. Three patients had positive results in the second SPT(75%). In conclusion, even when SPT is negative, the diagnosis of VSA should be made with clinical symptoms in consideration. In some cases, a second SPT may be required to confirm the diagnosis of VSA. | Hiroki Teragawa Yuichi Fujii Yuko Uchimura Tomohiro Ueda | 2017 | World Journal of Cardiology2017，9，3： | 0 |
