| 1 | ^(18)F-fluorodeoxyglucose positron emission tomography in the diagnosis of small pancreatic cancer显示文摘AIM:To investigate the role of 18 F-fluorodeoxyglucose positron emission tomography(FDG-PET) in the diagnosis of small pancreatic cancer. METHODS:This study involved 31 patients with proven invasive ductal cancer of the pancreas.The patients were divided into 3 groups according to the maximum diameter of the tumor:TS1(maximum tumor size≤2.0 cm) ,TS2(>2.0 cm and≤4.0 cm) or TS3-4(>4.0 cm) .The relationships between the TS and various diagnostic tools,including FDG-PET with dual time point evaluation,were analyzed. RESULTS:The tumors ranged from 1.3 to 11.0 cm in diameter.Thirty of the 31 patients(97%) had a positive FDG-PET study.There were 5 patients classified as TS1,15 as TS2 and 11 as TS3-4.The sensitivity of FDG-PET,computed tomography(CT) and magnetic resonanceimaging(MRI) were 100%,40%,0%in TS1,93%,93%,89%in TS2 and 100%,100%,100%in TS3-4. The sensitivity of FDG-PET was significantly higher in comparison to CT and MRI in patients with TS1(P< 0.032) .The mean standardized uptake values(SUVs) did not show a significant difference in relation to the TS(TS1:5.8±4.5,TS2:5.7±2.2,TS3-4:8.2±3.9) ,respectively.All the TS1 tumors(from 13 to 20 mm) showed higher SUVs in FDG-PET with dual time point evaluation in the delayed phase compared with the early phase,which suggested the lesions were malignant. CONCLUSION:These results indicate that FDG-PET with dual time point evaluation is a useful modality for the detection of small pancreatic cancers with a diameter of less than 20 mm. | Keiichi Okano Keitaro Kakinoki Shintaro Akamoto Masanobu Hagiike Hisashi Usuki Yuka Yamamoto Yoshihiro Nishiyama Yasuyuki Suzuki | 2011 | World Journal of Gastroenterology2011，17，2： | 12 |
| 2 | High-density and wide-bandwidth optical interconnects with silicon optical interposers [Invited]显示文摘One of the most serious challenges facing exponential performance growth in the information industry is the bandwidth bottleneck in interchip interconnects.We propose a photonics–electronics convergence system in response to this issue.To demonstrate the feasibility of the system,we fabricated a silicon optical interposer integrated with arrayed laser diodes,spot-size converters,optical splitters,optical modulators,photodetectors,and optical waveguides on a single silicon substrate.Using this system,20 Gbps error-free data links and a 30 Tbps∕cm2 bandwidth density were achieved.This bandwidth density is sufficient to meet the interchip interconnect requirements for the late 2010s. | Yutaka Urino Tatsuya Usuki Junichi Fujikata Masashige Ishizaka Koji Yamada Tsuyoshi Horikawa Takahiro Nakamura Yasuhiko Arakawa | 2014 | Photonics Research2014，2，3： | 3 |
| 3 | A patient with unresectable advanced pancreatic cancer achieving long-term survival with Gemcitabine chemotherapy显示文摘A 68-year-old female visited a local clinic with epigastralgia. A routine laboratory test revealed jaundice and liver dysfunction. She was referred to this hospital. Abdominal computed tomography (CT) and endoscopic retrograde cholangio-pancreatography (ERCP) revealed that the density of the entire pancreas had decreased,and showed dilatation of the common bile duct (CBD) and the main pancreatic duct (MPD). Pancreatic cancer was diagnosed by cytological examination analyzing the pancreatic juice obtained by ERCP. When jaundice had decreased the tumor was observed via laparotomy. No ascites,liver metastasis,or peritoneal dissemination was observed. The entire pancreas was a hard mass,and a needle biopsy was obtained from the head,body and tail of the pancreas. These biopsies diagnosed a poorly differentiated adenocarcinoma. Hepaticojejunostomy was thus performed,and postoperative progress was good. Chemotherapy with 1000 mg/body per week of gemcitabine was administered beginning 15 d postoperatively. However,the patient suffered relatively severe side effects,and it was necessary to change the dosing schedule of gemcitabine. Abdominal CT revealed a complete response (CR) after 3 treatments. Therefore,weekly chemotherapy was stopped and was changed to monthly administration. To date,for 4 years after chemotherapy,the tumor has not reappeared. | Yoshiki Okamoto Takashi Maeba Keitarou Kakinoki Keiichi Okano Kunihiko Izuishi Hisao Wakabayashi Hisashi Usuki Yasuyuki Suzuki | 2008 | World Journal of Gastroenterology2008，14，44： | 2 |
