| 1 | Preoperative evaluation of colorectal cancer using CT colonography, MRI, and PET/CT显示文摘Imaging studies are a major component in the evaluation of patients for the screening,staging and surveillance of colorectal cancer.This review presents commonly encountered findings in the diagnosis and staging of patients with colorectal cancer using computed tomography(CT)colonography,magnetic resonance imaging(MRI),and positron emission tomography(PET)/CT colonography.CT colonography provides important information for the preoperative assessment of T staging.Wall deformities are associated with muscular or subserosal invasion.Lymph node metastases from colorectal cancer often present with calcifications.CT is superior to detect calcified metastases.Three-dimensional CT to image the vascular anatomy facilitates laparoscopic surgery.T staging of rectal cancer by MRI is an established modality because MRI can diagnose rectal wall laminar structure.N staging in patients with colorectal cancer is still challenging using any imaging modality.MRI is more accurate than CT for the evaluation of liver metastases.PET/CT colonography isvaluable in the evaluation of extra-colonic and hepatic disease.PET/CT colonography is useful for obstructing colorectal cancers that cannot be traversed colonoscopically.PET/CT colonography is able to localize synchronous colon cancers proximal to the obstruction precisely.However,there is no definite evidence to support the routine clinical use of PET/CT colonography. | Shigeyoshi Kijima Takahiro Sasaki Koichi Nagata Kenichi Utano Alan T Lefor Hideharu Sugimoto | 2014 | World Journal of Gastroenterology2014,20,45: | 46 |
| 2 | Stem cell-derived exosomes as a therapeutic tool for cardiovascular disease显示文摘Mesenchymal stem cells(MSCs) have been used to treat patients suffering from acute myocardial infarction(AMI) and subsequent heart failure. Although it was originally assumed that MSCs differentiated into heart cells such as cardiomyocytes, recent evidence suggests that the differentiation capacity of MSCs is minimal and that injected MSCs restore cardiac function via the secretion of paracrine factors. MSCs secrete paracrine factors in not only naked forms but also membrane vesicles including exosomes containing bioactive substances such as proteins, messenger RNAs, and microR NAs. Although the details remain unclear, these bioactive molecules are selectively sorted in exosomes that are then released from donor cells in a regulated manner. Furthermore, exosomes are specifically internalized by recipient cells via ligand-receptor interactions. Thus, exosomes are promising natural vehicles that stably and specifically transport bioactive molecules to recipient cells. Indeed, stem cell-derived exosomes have been successfully used to treat cardiovascular disease(CVD), such as AMI, stroke, and pulmonary hypertension, in animal models, and their efficacy has been demonstrated. Therefore, exosome administration may be a promising strategy for the treatment of CVD. Furthermore, modifications of exosomal contents may enhance their therapeutic effects. Future clinical studies are required to confirm the efficacy of exosome treatment for CVD. | Etsu Suzuki Daishi Fujita Masao Takahashi Shigeyoshi Oba Hiroaki Nishimatsu | 2016 | World Journal of Stem Cells2016,8,9: | 19 |
| 3 | Adipose tissue-derived stem cells as a therapeutic tool for cardiovascular disease显示文摘Adipose tissue-deried stem cells( ADSCs) are adult stem cells that can be easily harvested from subcutaneous adipose tissue. Many studies have demonstrated that ADSCs differentiate into vascular endothelial cells(VECs), vascular smooth muscle cells(VSMCs), and cardiomyocytes in vitro and in vivo. However, ADSCs may fuse with tissue-resident cells and obtain the corresponding characteristics of those cells. If fusion occurs, ADSCs may express markers of VECs, VSMCs, and cardiomyocytes without direct differentiation into these cell types. ADSCs also produce a variety of paracrine factors such as vascular endothelial growth factor, hepatocyte growth factor, and insulin-like growth factor-1 that have proangiogenic and/or antiapoptotic activities. Thus, ADSCs have the potential to regenerate the cardiovascular system via direct differentiation into VECs, VSMCs, and cardiomyocytes, fusion with tissueresident cells, and the production of paracrine factors. Numerous animal studies have demonstrated the efficacy of ADSC implantation in the treatment of acute myocardial infarction(AMI), ischemic cardiomyopathy(ICM), dilated cardiomyopathy, hindlimb ischemia, and stroke. Clinical studies regarding the use of autologous ADSCs for treating patients with AMI and ICM have recently been initiated. ADSC implantation has been reported as safe and effective so far. Therefore, ADSCs appear to be useful for the treatment of cardiovascular disease. However, the tumorigenic potential of ADSCs requires careful evaluation before their safe clinical application. | Etsu Suzuki Daishi Fujita Masao Takahashi Shigeyoshi Oba Hiroaki Nishimatsu | 2015 | World Journal of Cardiology2015,7,8: | 17 |
| 4 | Measurement of prostaglandin metabolites is useful in diagnosis of small bowel ulcerations显示文摘BACKGROUND We recently reported on a hereditary enteropathy associated with a gene encoding a prostaglandin transporter and referred to as chronic enteropathy associated with SLCO2 A1 gene(CEAS). Crohn's disease(CD) is a major differential diagnosis of CEAS, because these diseases share some clinical features. Therefore, there is a need to develop a convenient screening test to distinguish CEAS from CD.AIM To examine whether prostaglandin E major urinary metabolites(PGE-MUM) can serve as a biomarker to distinguish CEAS from CD.METHODS This was a transactional study of 20 patients with CEAS and 98 patients with CD.CEAS was diagnosed by the confirmation of homozygous or compound heterozygous mutation of SLCO2 A1. We measured the concentration of PGEMUM in spot urine by radioimmunoassay, and the concentration was compared between the two groups of patients. We also determined the optimal cut-off value of PGE-MUM to distinguish CEAS from CD by receiver operating characteristic(ROC) curve analysis.RESULTS Twenty Japanese patients with CEAS and 98 patients with CD were enrolled.PGE-MUM concentration in patients with CEAS was significantly higher than that in patients with CD(median 102.7 vs 27.9 μg/g × Cre, P < 0.0001). One log unit increase in PGE-MUM contributed to 7.3 increase in the likelihood for the diagnosis of CEAS [95% confidence interval(CI) 3.2-16.7]. A logistic regression analysis revealed that the association was significant even after adjusting confounding factors(adjusted odds ratio 29.6, 95%CI 4.7-185.7). ROC curve analysis revealed the optimal PGE-MUM cut-off value for the distinction of CEAS from CD to be 48.9 μg/g × Cre with 95.0% sensitivity and 79.6% specificity.CONCLUSION PGE-MUM measurement is a convenient, non-invasive and useful test for the distinction of CEAS from CD. | Yuichi Matsuno Junji Umeno Motohiro Esaki Yoichiro Hirakawa Yuta Fuyuno Yasuharu Okamoto Atsushi Hirano Shigeyoshi Yasukawa Fumihito Hirai Toshiyuki Matsui Shuhei Hosomi Kenji Watanabe Naoki Hosoe Haruhiko Ogata Tadakazu Hisamatsu Shunichi Yanai Shuji Kochi Koichi Kurahara Tsuneyoshi Yao Takehiro Torisu Takanari Kitazono Takayuki Matsumoto | 2019 | World Journal of Gastroenterology2019,25,14: | 5 |
| 5 | Laterally spreading tumors:Limitations of computed tomography colonography显示文摘AIM:To prospectively investigate the detection rate of laterally spreading tumors(LSTs)of the colorectum by computed tomography(CT)colonography(CTC).METHODS:Patients with LSTs measuring≥20 mm detected during colonoscopy were prospectively enrolled in the study.All patients underwent colonoscopy and subsequent CTC on the same day.CTC was performed using multi-detector CT without contrast in the prone and supine positions.Two radiologists blinded to the existence of LSTs read the virtual endoscopic images as well as 2-D images.LSTs were classified into granular and non-granular types based on colonoscopic appearance.RESULTS:Forty-seven pathologically proven LSTs were evaluated prospectively.Histology included adenomas in 19,mucosal cancers in 19 and T1 cancers in 9.The mean diameter of the LSTs was 35.1 mm.Twenty-eight(60%)LSTs were correctly identified by CTC,and the configuration was similar to the colonoscopic appearance in most cases.Detection rate for the granular type was significantly higher than that for the nongranular type(71%vs 31%,P=0.013).Detection rate of adenomas was significantly lower than mucosal cancers(32%vs 79%,P=0.008)and T1 cancers(32%vs 78%,P=0.042).CONCLUSION:The detection rate of LSTs by CTC,particularly the non-granular type was not acceptable.Practitioners should be aware of the relatively low detection rate when using CTC. | Kazutomo Togashi Kenichi Utano Shigeyoshi Kijima Yosuke Sato Hisanaga Horie Keijirou Sunada Alan T Lefor Hideharu Sugimoto Yoshikazu Yasuda | 2014 | World Journal of Gastroenterology2014,20,46: | 4 |
| 6 | Chronic kidney disease and erectile dysfunction显示文摘Erectile dysfunction(ED) is a common condition among male chronic kidney disease(CKD) patients.Its prevalence is estimated to be approximately 80% among these patients.It has been well established that the production of nitric oxide from the cavernous nerve and vascular endothelium and the subsequent production of cyclic GMP are critically important in initiating and maintaining erection.Factors affecting these pathways can induce ED.The etiology of ED in CKD patients is multifactorial.Factors including abnormalities in gonadal-pituitary system,disturbance in autonomic nervous system,endothelial dysfunction,anemia(and erythropoietin deficiency),secondary hyperparathyroidism,drugs,zinc deficiency,and psychological problems are implicated in the occurrence of ED.An improvement of general conditions is the first step of treatment.Sufficient dialysis and adequate nutritional intake are necessary.In addition,control of anemia and secondary hyperparathyroidism is required.Changes of drugs that potentially affect erectile function may be necessary.Further,zinc supplementation may be necessary whenzinc deficiency is suspected.Phosphodiesterase type 5 inhibitors(PDE5Is) are commonly used for treating ED in CKD patients,and their efficacy was confirmed by many studies.Testosterone replacement therapy in addition to PDE5 Is may be useful,particularly for CKD patients with hypogonadism.Renal transplantation may restore erectile function.ED is an early marker of cardiovascular disease(CVD),which it frequently precedes; therefore,it is crucial to examine the presence of ED in CKD patients not only for the improvement of the quality of life but also for the prevention of CVD attack. | Etsu Suzuki Hiroaki Nishimatsu Shigeyoshi Oba Masao Takahashi Yukio Homma | 2014 | World Journal of Nephrology2014,3,4: | 3 |
