| 1 | Transarterial chemoembolization for hepatocellular carcinoma: A review of techniques显示文摘Hepatocellular carcinoma(HCC)is one of the most common malignant diseases worldwide.While curative therapies,including resection,liver transplantation,and percutaneous ablation(percutaneous ethanol injection and radiofrequency ablation),are applicable for only a portion of the HCC population,transcatheter arterial chemoembolization(TACE)has been recognized as an effective palliative treatment option for patients with advanced HCC.TACE is also used even for single HCCs in which it is difficult to perform surgical resection or locoregional treatment due to systemic co-morbidities or anatomical problems.TACE has become widely adopted in the treatment of HCC.By using computed tomography-angiography,TACE is capable of performing diagnosis and treatment at the same time.Furthermore,TACE plays an important role in the multidisciplinary treatment for HCC when combined with other treatment.In this review,we first discuss the history of TACE,and then review the previous findings about techniques of achieving a locoregional treatment effect(liver infarction treatment,e.g.,ultra-selective TACE,balloon-occluded TACE),and the use of TACE as a drugdelivery system for anti-cancer agents(palliative,e.g.,platinum complex agents,drug-eluting beads)for multiple lesions. | Norihiro Imai Masatoshi Ishigami Yoji Ishizu Teiji Kuzuya Takashi Honda Kazuhiko Hayashi Yoshiki Hirooka Hidemi Goto | 2014 | World Journal of Hepatology2014，6，12： | 24 |
| 2 | Feasibility of cold snare polypectomy in Japan: A pilot study显示文摘AIM: To investigate the feasibility of cold snare polypectomy(CSP) in Japan.METHODS: The outcomes of 234 non-pedunculated polyps smaller than 10 mm in 61 patients who underwent CSP in a Japanese referral center were retrospectively analyzed. The cold snare polypectomies were performed by nine endoscopists with no prior experience in CSP using an electrosurgical snare without electrocautery.RESULTS: CSPs were completed for 232 of the 234 polyps. Two(0.9%) polyps could not be removed without electrocautery. Immediate postpolypectomy bleeding requiring endoscopic hemostasis occurred in eight lesions(3.4%; 95%CI: 1.1%-5.8%), but all were easily managed. The incidence of immediate bleeding after CSP for small polyps(6-9 mm) was significantly higher than that of diminutive polyps(≤ 5 mm; 15% vs 1%, respectively). Three(5%) patients complained of minor bleeding after the procedure but required no intervention. The incidence of delayed bleeding requiringendoscopic intervention was 0.0%(95%CI: 0.0%-1.7%). In total, 12% of the resected lesions could not be retrieved for pathological examination. Tumor involvement in the lateral margin could not be histologically assessed in 70(40%) lesions.CONCLUSION: CSP is feasible in Japan. However, immediate bleeding, retrieval failure and uncertain assessment of the lateral tumor margin should not be underestimated. Careful endoscopic diagnosis before and evaluation of the tumor residue after CSP are recommended when implementing CSP in Japan. | Yoji Takeuchi Takeshi Yamashina Noriko Matsuura Takashi Ito Mototsugu Fujii Kengo Nagai Fumi Matsui Tomofumi Akasaka Noboru Hanaoka Koji Higashino Hiroyasu Iishi Ryu Ishihara Henrik Thorlacius Noriya Uedo | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，17： | 14 |
| 3 | Prognostic value of KRAS and BRAF mutations in curatively resected colorectal cancer显示文摘AIM: To investigate the prognostic role of KRAS and BRAF mutations after adjustment for microsatellite instability(MSI) status in Japanese colorectal cancer(CRC) population.METHODS: We assessed KRAS and BRAF mutations and MSI status in 813 Japanese patients with curatively resected, stage Ⅰ-Ⅲ CRC and examined associations of these mutations with disease-free survival(DFS) and overall survival(OS) using uni- and multivariate Cox proportional hazards models.RESULTS: KRAS and BRAF mutations were detected in 312(38%) of 812 and 40(5%) of 811 tumors, respectively. KRAS mutations occurred more frequently in females than in males(P = 0.02), while the presence of BRAF mutations was significantly associated with the female gender(P = 0.006), proximal tumor location(P < 0.001), mucinous or poorly differentiated histology(P < 0.001), and MSI-high tumors(P < 0.001). After adjusting for relevant variables, including MSI status, KRAS mutations were associated with poorer DFS(HR = 1.35; 95%CI: 1.03-1.75) and OS(HR = 1.46; 95%CI: 1.09-1.97). BRAF mutations were poor prognostic factors for DFS(HR = 2.20; 95%CI: 1.19-4.06) and OS(HR = 2.30; 95%CI: 1.15-4.71). Neither the BRAF by MSI interaction test nor the KRAS by MSI interaction test yielded statistically significant results for DFS and OS.CONCLUSION: KRAS and BRAF mutations are associated with inferior survival, independent of MSI status, inJapanese patients with curatively resected CRC. | Shigenori Kadowaki Miho Kakuta Shuhei Takahashi Akemi Takahashi Yoshiko Arai Yoji Nishimura Toshimasa Yatsuoka Akira Ooki Kensei Yamaguchi Keitaro Matsuo Kei Muro Kiwamu Akagi | 2015 | World Journal of Gastroenterology2015，21，4： | 14 |
| 4 | Pink-color sign in esophageal squamous neoplasia, and speculation regarding the underlying mechanism显示文摘AIM:To investigate the reasons for the occurrence of the pink-color sign of iodine-unstained lesions. METHODS:In chromoendoscopy, the pink-color sign of iodine-unstained lesions is recognized as useful for the diagnosis of esophageal squamous cell carcinoma. Patients with superficial esophageal neoplasms treated by endoscopic resection were included in the study. Areas of mucosa with and without the pink-color sign were evaluated histologically. The following histologic features that were possibly associated with the pinkcolor sign were evaluated. The keratinous layer and basal cell layer were classified as present or absent. Cellular atypia was classified as high grade, moderate grade or low grade, based on nuclear irregularity, mitotic figures, loss of polarity, chromatin pattern and nuclear/cytoplasmic ratio. Vascular change was assessed based on dilatation, tortuosity, caliber change and variability in shape. Vessels with these four findings were classified as positive for vascular change. Endoscopic images of the lesions were captured immediately after iodine staining, 2-3 min after iodine staining and after complete fading of iodine staining. Quantitative analysis of color changes after iodine staining was also performed. RESULTS:A total of 61 superficial esophageal neoplasms in 54 patients were included in the study. The lesions were located in the cervical esophagus in one case, the upper thoracic esophagus in 10 cases, the mid-thoracic esophagus in 33 cases, and the lower thoracic esophagus in 17 cases. The median diameter of the lesions was 20 mm (range:2-74 mm). Of the 61 lesions, 28 were classified as pink-color sign positive and 33 as pink-color sign negative. The histologic diagnosis was high-grade intraepithelial neoplasia (HGIN) or cancer invading into the lamina propria in 26 of the 28 pink-color sign positive lesions. There was a significant association between pink-color sign positive epithelium and HGIN or invasive cancer (P = 0.0001). Univariate analyses found that absence of the keratinous layer and cellular atypia were significantly associated with the pink-color sign. After Bonferroni correction, there were no significant associations between the pink-color sign and presence of the basal membrane or vascular change. Multivariate analyses found that only absence of the keratinous layer was independently associated with the pink-color sign (OR = 58.8, 95%CI:5.5-632).Quantitative analysis was performed on 10 superficial esophageal neoplasms with both pink-color sign positive and negative areas in 10 patients. Pink-color sign positive mucosa had a lower mean color value in the late phase (pinkish color) than in the early phase (yellowish color), and had similar mean color values in the late and final phases. These findings suggest that pinkcolor positive mucosa underwent color fading from the color of the iodine (yellow) to the color of the mucosa (pink) within 2-3 min after iodine staining. Pink-color sign negative mucosa had similar mean color values in the late and early phases (yellowish color), and had a lower mean color value in the final phase (pinkish color) than in the late phase. These findings suggest that pink-color sign negative mucosa did not undergo color fading during the 2-3 min after iodine staining, and underwent color fading only after spraying of sodium thiosulfate. CONCLUSION:The pink-color sign was associated with absence of the keratinous layer. This sign may be caused by early fading of iodine staining. | Ryu Ishihara Hiromitsu Kanzaki Hiroyasu Iishi Kengo Nagai Fumi Matsui Takeshi Yamashina Noriko Matsuura Takashi Ito Mototsugu Fujii Sachiko Yamamoto Noboru Hanaoka Yoji Takeuchi Koji Higashino Noriya Uedo Masaharu Tatsuta Yasuhiko Tomita Shingo Ishiguro | 2013 | World Journal of Gastroenterology2013，19，27： | 10 |
| 5 | Beetle elytron plate and the synergistic mechanism of a trabecular-honeycomb core structure显示文摘For the development of lightweight biomimetic materials, the compressive properties of the beetle elytron plate(BEP, a type of biomimetic sandwich plate inspired from beetle elytra) and the underlying mechanism thereof were investigated. With the following results:(1) The shared mechanism of trabeculae was revealed by using structural analysis. It is further predicted that a BEP with hollow trabeculae should possess enhanced compressive properties.(2) When the trabecular number(N) in a hexagonal unit of the honeycomb is less than three, the compressive strength of the BEP is rapidly increased with the increment of N. When N is over four, the deformation capacity is significantly improved because of the arising of S-type buckling deformation in the core structure of the BEP. Furthermore, the definition of the BEP is proposed combined with the biological structure of the beetle elytra.(3) When N=6 and the external diameter of trabeculae is equal to the length of honeycomb walls, the synergistic mechanism between the trabeculae and the honeycomb walls in BEPs is fully exerted. Namely, the trabecula restricts the deformation of the honeycomb walls; in turn, the honeycomb walls provide lateral support for the trabecula. This mechanism leads the core in the BEP to generate an S-type global buckling deformation producing the best compressive properties. The results will greatly impact the biomimetic field of beetle elytra and many industries in which honeycomb structure also serves as a key component. | CHEN JinXiang ZHANG XiaoMing OKABE Yoji XIE Juan XU MengYe | 2019 | Science China(Technological Sciences)2019，62，1： | 7 |
| 6 | Role of hepatectomy for recurrent or initially unresectable hepatocellular carcinoma显示文摘As a result of donor shortage and high postoperative morbidity and mortality after liver transplantation,hepatectomy is the most widely applicable and reliable option for curative treatment of hepatocellular carcinoma(HCC).Because intrahepatic tumor recurrence is frequent after loco-regional therapy,repeated treatments are advocated provided background liver function is maintained.Among treatments including local ablation and transarterial chemoembolization,hepatectomy provides the best long-term outcomes,but studies comparing hepatectomy with other nonsurgical treatments require careful review for selection bias.In patients with initially unresectable HCC,transarterial chemo-or radio-embolization,and/or systemic chemotherapy can down-stage the tumor and conversion to resectable HCC is achieved in approximately 20%of patients.However,complete response is rare,and salvage hepatectomy is essential to help prolong patients’survival.To counter the short recurrence-free survival,excellent overall survival is obtained by combining and repeating different treatments.It is important to recognize hepatectomy as a complement,rather than a contraindication,to other nonsurgical treatments in a mul-tidisciplinary approach for patients with HCC,including recurrent or unresectable tumors. | Yoji Kishi Kazuaki Shimada Satoshi Nara Minoru Esaki Tomoo Kosuge | 2014 | World Journal of Hepatology2014，6，12： | 5 |

| 9 | Management of local recurrence after endoscopic resection of neoplastic colonic polyps显示文摘A proportion of neoplastic polyps are incompletely resected, resulting in local recurrence, especially after resection of large polyps or piecemeal resection. Local recurrences that develop after endoscopic resection of intramucosal neoplasms that lacked risk factors for lymph node metastasis or positive vertical margins are usually treated endoscopically. Endoscopic submucosal dissection(ESD) is indicated for local residual or recurrent early carcinomas after endoscopic resection. However, ESD for such recurrent lesions is technically difficult and is typically a lengthy procedure. Underwater endoscopic mucosal resection(UEMR), which was developed in 2012, is suitable for recurrent or residual lesions and reportedly achieves superior en bloc resection rates and endoscopic complete resection rates than conventional EMR. However, a large recurrent lesion is a negative independent predictor of successful en bloc resection and of complete endoscopic removal. We therefore perform UEMR for relatively small(≤ 10-15 mm) recurrent lesions and ESD for larger lesions. | Satoki Shichijo Yoji Takeuchi Noriya Uedo Ryu Ishihara | 2018 | World Journal of Gastrointestinal Endoscopy2018，10，12： | 3 |
| 10 | Influence of NUDT15 variants on hematological pictures of patients with inflammatory bowel disease treated with thiopurines显示文摘AIM The single nucleotide polymorphism(SNP) c.415C>T in exon 3 of NUDT15 affects thiopurine-induced leukopenia in Asian patients with Crohn's disease. Meanwhile, three additional genetic variants of NUDT15 were reported in patients with acute lymphoblastic leukemia. We evaluated the effects of these additional genetic variants of NUDT15 in patients with inflammatory bowel disease(IBD) treated with thiopurines.METHODS Ninety-six Japanese patients with IBD were enrolled. Genotyping for the NUDT15 and TPMT genes was performed using Custom Taq Man SNP genotyping assays or Sanger sequencing. The changes in white blood cell(WBC) count, mean corpuscular volume(MCV), platelet count, hemoglobin, CRP, amylase, albumin, AST, ALT, and ESR were evaluated.RESULTS Genetic variants of exon 1 and exon 3 of NUDT15 were identified in 24 of 96 patients(25.0%). C.52G > A and c.36_37 insG GAGTC in exon 1 were found in three patients each. All three patients with c.36_37 insG GAGTC in exon 1 were heterozygotes of p.Arg139 Cys in exon 3. Eighteen patients had p.Arg139 Cys in exon 3 alone. The WBC count gradually decreased after initiation of thiopurine treatment in the mutated cases(n = 24), and was significantly lower at 6, 8, 10, and 16 wk(P = 0.0271, 0.0037, 0.0051, and 0.0185, respectively). The WBC counts were also evaluated in patients with and without prednisolone treatment. In the patients with prednisolone treatment, the WBC count tended to show a greater decrease in the mutated cases, with significant differences at 8 and 10 wk(P = 0.012 and 0.029, respectively). In the patients without prednisolone treatment, the WBC count was significantly lower at 2, 4, 8, and 14 wk in mutated cases(P = 0.0196, 0.0182, 0.0237 and 0.0241, respectively). MCV increased after starting thiopurine treatment in the mutated cases, and was significantly higher at 10 wk(P = 0.0085). Platelet count, hemoglobin, CRP, amylase, albumin, AST, ALT and ESR did not differ significantly between the wildtype and mutated cases. TPMT mutations were not found in any of the patients.CONCLUSION Mutations in exon 1 of NUDT15 also affect thiopurineinduced leukopenia in patients with IBD. To discuss thiopurine-induced leukopenia in more detail, investigation of SNPs in both exon 1 and exon 3 of NUDT15 is needed. | Yuichiro Kojima Yosuke Hirotsu Wataru Omata Makoto Sugimori Shinya Takaoka Hiroshi Ashizawa Keiko Nakagomi Dai Yoshimura Kenji Hosoda Yoji Suzuki Hitoshi Mochizuki Masao Omata | 2018 | World Journal of Gastroenterology2018，24，4： | 3 |

| 16 | Light is an Important Limiting Factor for the Vertical Distribution of the Largest Extant Benthic Foraminifer Cycloclypeus carpenteri显示文摘Cycloclypeus carpenteri is the largest extant benthic foraminifer,dwelling in the deep euphotic zone(a water depth between 60 and 130 m)of the warm oligotrophic Indo-West Pacific.This foraminifer harbors diatom endosymbionts and the foraminifer-microalgal association acts like a holobiont.To verify that light is an important limiting factor controlling the vertical(depth)distribution of living Cycloclypeus holobionts,their physiological responses to light intensity were examined by short-term metabolic measurements and long-term incubations.Net oxygen production(OP)rates measured under different light levels using an oxygen microelectrode indicate that Cycloclypeus holobionts are daily net primary producers adapted to low light levels,with slight photoinhibition(reduced net OP rates relative to a light-saturated rate)over 100μmol photons m^(−2)s^(−1).Long-term growth increments of asexually reproduced juveniles incubated for two months at different light levels ranging from 0 to 100μmol photons m^(−2)s^(−1) show that Cycloclypeus holobionts are adapted to a low light level(∼5μmol photons m^(−2)s^(−1)),but can be acclimatized to a certain low light ranges(<50μmol photons m^(−2)s^(−1)).These experimental results confirm that light is an important environmental gradient affecting the vertical distribution of Cycloclypeus holobionts. | Kazuhiko Fujita Yoji Kanda Takashi Hosono | 2022 | Journal of Earth Science2022，33，6： | 2 |
