| 1 | Autotrophic denitrification for nitrate and nitrite removal using sulfur-limestone显示文摘Sulfur-limestone was used in the autotrophic denitrification process to remove the nitrate and nitrite in a lab scale upflow biofilter.Synthetic water with four levels of nitrate and nitrite concentrations of 10,40,70 and 100 mg N/L was tested.When treating the low concentration of nitrate-or nitrite-contaminated water(10,40 mg N/L),a high removal rate of about 90% was achieved at the hydraulic retention time(HRT) of 3 hr and temperature of 20-25°C.At the same HRT,50% of the nitrate or nitrite could be removed even at the low temperature of 5-10°C.For the higher concentration nitrate and nitrite(70,100 mg N/L),longer HRT was required.The batch test indicated that influent concentration,HRT and temperature are important factors afiecting the denitrification eficiency.Molecular analysis implied that nitrate and nitrite were denitrified into nitrogen by the same microorganisms.The sequential two-step-reactions from nitrate to nitrite and from nitrite to the next-step product might have taken place in the same cell during the autotrophic denitrification process. | Weili Zhou Yejue Sun Bingtao Wu Yue Zhang Min Huang Toshiaki Miyanaga Zhenjia Zhang | 2011 | Journal of Environmental Sciences2011，23，11： | 34 |
| 2 | Endoscopic characteristics of small intestinal malignant tumors observed by balloon-assisted enteroscopy显示文摘BACKGROUND Capsule endoscopy and balloon-assisted enteroscopy(BAE) enable visualization of rare small bowel conditions such as small intestinal malignant tumors.However,details of the endoscopic characteristics of small intestinal malignant tumors are still unknown.AIM To elucidate the endoscopic characteristics of small intestinal malignant tumors.METHODS From March 2005 to February 2017,1329 BAE procedures were performed at Keio University Hospital. Of these procedures,malignant tumors were classified into three groups,Group 1: epithelial tumors including primary small intestinal cancer,metastatic small intestinal cancer,and direct small intestinal invasion by an adjacent organ cancer; Group 2: small intestinal malignant lymphoma; and Group 3,small intestinal gastrointestinal stromal tumors. We systematically collected clinical and endoscopic data from patients' medical records to determine the endoscopic characteristics for each group.RESULTS The number of patients in each group was 16(Group 1),23(Group 2),and 6(Group 3),and the percentage of solitary tumors was 100%,43.5%,and 100%,respectively(P < 0.001). Patients' clinical background parameters including age,symptoms,and laboratory data were not significantly different between the groups. Seventy-five percent of epithelial tumors(Group 1) were located in the upper small intestine(duodenum and ileum),and approximately 70% of gastrointestinal stromal tumors(Group 3) were located in the jejunum. Solitary protruding or mass-type tumors were not seen in malignant lymphoma(Group2)(P < 0.001). Stenosis was seen more often in Group 1,(68.8%,27.3%,and 0%;Group 1,2,and 3,respectively; P = 0.004). Enlarged white villi inside and/or surrounding the tumor were seen in 12.5%,54.5%,and 0% in Group 1,2,and 3,respectively(P = 0.001).CONCLUSION The differential diagnosis of small intestinal malignant tumors could be tentatively made based on BAE findings. | Tomofumi Horie Naoki Hosoe Kaoru Takabayashi Yukie Hayashi Kenji JL Limpias Kamiya Ryoichi Miyanaga Shinta Mizuno Kayoko Fukuhara Seiichiro Fukuhara Makoto Naganuma Masayuki Shimoda Haruhiko Ogata Takanori Kanai | 2019 | World Journal of Gastrointestinal Endoscopy2019，11，5： | 4 |
| 3 | Endoscopic 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 | 2020 | World Journal of Gastrointestinal Endoscopy2020，12，1： | 3 |
