1Preoperative 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 2014World Journal of Gastroenterology2014,20,45:46
2Endoscopic removal of foreign bodies:A retrospective study in Japan显示文摘BACKGROUND The ingestion of foreign bodies(FBs)and food bolus impaction(FBI)in the digestive tract are commonly encountered clinical problems.Methods to handle such problems continue to evolve offering advantages,such as the avoidance of surgery,reduced cost,improved visualization,reduced morbidity,and high removal success rate.However,to date,no studies have evaluated the endoscopic management of FBs in Japan.AIM To elucidate level of safety and efficacy in the endoscopic management of FBs and FBI.METHODS A total of 215 procedures were performed at Keio University Hospital between November 2007 and August 2018.Data were collected from medical charts,and endoscopic details were collected from an endoscopic reporting system.Procedures performed with a flexible gastrointestinal endoscope were only taken into account.Patients who underwent a technique involving FB or FBI from the digestive tract were only included.Data on patient sex,patient age,outpatient,inpatient,FB type,FB location,procedure time,procedure type,removal device type,success,and technical complications were reviewed and analyzed retrospectively.RESULTS Among the 215 procedures,136(63.3%)were performed in old adults(≥60 years),180(83.7%)procedures were performed in outpatients.The most common type of FBs were press-through-pack(PTP)medications[72(33.5%)cases],FBI[47(21.9%)],Anisakis parasite(AP)[41(19.1%)cases].Most FBs were located in the esophagus[130(60.5%)cases]followed by the stomach[68(31.6%)cases].AP was commonly found in the stomach[39(57.4%)cases],and it was removed using biopsy forceps in 97.5%of the cases.The most common FBs according to anatomical location were PTP medications(40%)and dental prostheses(DP)(40%)in the laryngopharynx,PTP(48.5%)in the esophagus,AP(57.4%)in the stomach,DP(37.5%)in the small intestine and video capsule endoscopy device(75%)in the colon.A transparent cap with grasping forceps was the most commonly used device[82(38.1%)cases].The success rate of the procedure was 100%,and complication were observed in only one case(0.5%).CONCLUSION Endoscopic management of FBs and FBI in our Hospital is extremely safe and effective.Kenji JL Limpias Kamiya Naoki Hosoe Kaoru Takabayashi Yukie Hayashi Xi Sun Ryoichi Miyanaga Kayoko Fukuhara Seiichiro Fukuhara Makoto Naganuma Atsushi Nakayama Motohiko Kato Tadateru Maehata Rieko Nakamura Koichi Ueno Junichi Sasaki Yuko Kitagawa Naohisa Yahagi Haruhiko Ogata Takanori Kanai 2020World Journal of Gastrointestinal Endoscopy2020,12,1:3

11Application of monoclonal antibody against ginsenoside in ginseng research:a review显示文摘Panax genus belonging to a family of Araliaceae grow in Asia(9 species)and in North America(2 species).Especially Panax ginseng was listed in Chinese medical book,Shennong's Classic of Materia Medica approximately 2 thousand years ago and Panax species are now one of the most important natural medicine.Since Panax species contain approximately 260 ginsenosides,its quality control and pharmacological movement of ginsenoside in body are not enough understanding.Monoclonal antibodies against ginsenosides were prepared and set up the enzyme linked immunosorbent assay system for the quality control of natural product.Furthermore,we developed Eastern blotting system using monoclonal antibodies resulted that protopanaxadiol and protopanaxatriol group ginsenosides can be separately stained by two corresponding monoclonal antibodies,respectively.It became evident that the ginseng slice was stained by Eastern blotting system.Histochemical staining of ginseng can make clear the ginsenoside-Rb1 distribution in cells and tissues.Double Eastern blotting system facilitated by two monoclonal antibodies like anti-ginsenoside-Rb1 and anti-ginsenoside-Rg1 monoclonal antibodies gives several information such as sugar number,structure,and qualitative/quantitative evaluation.Immunoaffinity column combined with monoclonal antibodies succeeded one-step isolation of ginsenoside and make it possible to prepare knockout extract of which only antigen molecule was removed suggesting the pharmacological and biological value of antigen molecule in the crude extract.Yui Sasaki Koichi Shimizu Hitoshi Watanabe Yukihiro Shoyama 2021Traditional Medicine Research2021,6,3:1
