1Initial management for acute lower gastrointestinal bleeding显示文摘Acute lower gastrointestinal bleeding(LGIB) is a common indication for hospital admission. Patients with LGIB often experience persistent or recurrent bleeding and require blood transfusions and interventions, such as colonoscopic,radiological, and surgical treatments. Appropriate decision-making is needed to initially manage acute LGIB, including emergency hospitalization, timing of colonoscopy, and medication use. In this literature review, we summarize the evidence for initial management of acute LGIB. Assessing various clinical factors,including comorbidities, medication use, presenting symptoms, vital signs, and laboratory data is useful for risk stratification of severe LGIB, and for discriminating upper gastrointestinal bleeding. Early timing of colonoscopy had the possibility of improving identification of the bleeding source, and the rate of endoscopic intervention, compared with elective colonoscopy. Contrast-enhanced computed tomography before colonoscopy may help identify stigmata of recent hemorrhage on colonoscopy, particularly in patients who can be examined immediately after the last hematochezia. How to deal with nonsteroidal antiinflammatory drugs(NSAIDs) and antithrombotic agents after hemostasis should be carefully considered because of the risk of rebleeding and thromboembolic events. In general, aspirin as primary prophylaxis for cardiovascular events and NSAIDs were suggested to be discontinued after LGIB. Managing acute LGIB based on this information would improve clinical outcomes. Further investigations are needed to distinguish patients with LGIB who require early colonoscopy and hemostatic intervention.Tomonori Aoki Yoshihiro Hirata Atsuo Yamada Kazuhiko Koike 2019World Journal of Gastroenterology2019,25,1:28

3Clinical benefit of radiation therapy and metallic stenting for unresectable hilar cholangiocarcinoma显示文摘AIM:To determine the efficacy of external beam radiotherapy(EBRT),with or without intraluminal brachytherapy(ILBT),in patients with non-resected locally advanced hilar cholangiocarcinoma.METHODS:We analyzed 64 patients with locally advanced hilar cholangiocarcinoma,including 25 who underwent resection(17 curative and 8 non-curative),28 treated with radiotherapy,and 11 who received best supportive care(BSC).The radiotherapy group received EBRT(50 Gy,30 fractions),with 11 receiving an additional 24 Gy(4 fractions) ILBT by iridium-192 with remote after loading.ILBT was performed using percutaneous transhepatic biliary drainage(PTBD) route.Uncovered metallic stents(UMS) were inserted into nonresected patients with obstructive jaundice,with the exception of four patients who received percutaneous transhepatic biliary drainage only.UMS were placed endoscopically or percutaneously,depending on the initial drainage procedure.The primary endpoints were patient death or stent occlusion.Survival time of patients in the radiotherapy group was compared with that of patients in the resection and BSC groups.Stent patency was compared in the radiotherapy and BSC groups.RESULTS:No statistically significant differences in patient characteristics were found among the resection,radiotherapy,and BSC groups.Three patients in the radiotherapy group and one in the BSC group did not receive UMS insertion but received PTBD alone;cholangitis occurred after endoscopic stenting,and patients were treated with PTBD.A total of 16 patients were administered additional systemic chemotherapy(5-fluorouracil-based regimen in 9,S-1 in 6,and gemcitabine in 1).Overall survival varied significantly among groups,with median survival times of 48.7 mo in the surgery group,22.1 mo in the radiotherapy group,and 5.7 mo in the BSC group.Patients who underwent curative resection survived significantly longer than those who were not candidates for surgery(P = 0.0076).Cumulative survival in the radiotherapy group was significantly longer than in the BSC group(P = 0.0031),but did not differ significantly from those in the non-resection group.Furthermore,the median survival time of patients in the radiotherapy group who were considered for possible resection(excluding the seven patients who were not candidates for surgery due to comorbid disease or age) was 25.9 mo.Stent patency was evaluated only in the 24 patients who received a metallic stent.Stent patency was significantly longer in the radiotherapy than in the BSC group(P = 0.0165).Biliary drainage was not eliminated in any patient.To determine the efficacy of ILBT,we compared survival time and stent patency in the EBRT alone and EBRT plus ILBT groups.However,we found no significant difference in survival time between groups or for stent patencies.Hemorrhagic gastroduodenal ulcers were observed in 5 patients(17.9%),three in the EBRT plus ILBT group and two in the EBRT alone group.Ulcers occurred 5 mo,7 mo,8 mo,16 mo,and 29 mo following radiotherapy.All patients required hospitalization,but blood transfusions were unnecessary.All 5 patients recovered following the administration of anti-ulcer medication.CONCLUSION:Radiotherapy improved patient prognosis and the patency of uncovered metallic stents in patients with locally advanced hilar cholangiocarcinoma,but ILBT provided no additional benefits.Hiroyuki Isayama Takeshi Tsujino Yousuke Nakai Takashi Sasaki Keiichi Nakagawa Hideomi Yamashita Taku Aoki Kazuhiko Koike 2012World Journal of Gastroenterology2012,18,19:24

5Assessment of the validity of the clinical pathway for colon endoscopic submucosal dissection显示文摘AIM: To determine the effective hospitalization period as the clinical pathway to prepare patients for endoscopic submucosal dissection (ESD). METHODS: This is a retrospective observational study which included 189 patients consecutively treated by ESD at the National Cancer Center Hospital from May 2007 to March 2009. Patients were divided into 2 groups; patients in group A were discharged in 5 d and patients in group B included those who stayed longer than 5 d. The following data were collected for both groups: mean hospitalization period, tumor site, median tumor size, post-ESD rectal bleeding requiring urgent endoscopy, perforation during or after ESD, abdominal pain, fever above 38 ℃, and blood test results positive for inflammatory markers before and after ESD. Each parameter was compared after data collection. RESULTS: A total of 83% (156/189) of all patients could be discharged from the hospital on day 3 postESD. Complications were observed in 12.1% (23/189) of patients. Perforation occurred in 3.7% (7/189) of patients. All the perforations occurred during the ESD procedure and they were managed with endoscopic clipping. The incidence of post-operative bleeding was 2.6% (5/189); all the cases involved rectal bleeding. We divided the subjects into 2 groups: tumor diameter ≥ 4 cm and < 4 cm; there was no significant difference between the 2 groups (P = 0.93, χ 2 test with Yates correction). The incidence of abdominal pain was 3.7% (7/189). All the cases occurred on the day of the procedure or the next day. The median white blood cell count was 6800 ± 2280 (cells/μL; ± SD) for group A, and 7700 ± 2775 (cells/μL; ± SD) for group B, showing a statistically significant difference (P = 0.023, t-test). The mean C-reactive protein values the day after ESD were 0.4 ± 1.3 mg/dL and 0.5 ± 1.3 mg/dL for groups A and B, respectively, with no significant difference between the 2 groups (P = 0.54, t -test). CONCLUSION: One-day admission is sufficient in the absence of complications during ESD or early postoperative bleeding.Takaya Aoki Takeshi Nakajima Yutaka Saito Takahisa Matsuda Taku Sakamoto Takao Itoi Yassir Khiyar Fuminori Moriyasu 2012World Journal of Gastroenterology2012,18,28:22
6Effectiveness of probiotic therapy for the prevention of relapse in patients with inactive ulcerative colitis显示文摘AIM: to evaluate the effectiveness of probiotic therapy for suppressing relapse in patients with inactive ulcerative colitis(UC).METHODS: Bio-Three tablets, each containing 2 mg of lactomin(Streptococcus faecalis T-110), 10 mg of Clostridium butyricum TO-A, and 10 mg of Bacillus mesentericus TO-A, were used as probiotic therapy.Sixty outpatients with UC in remission were randomly assigned to receive 9 Bio-Three tablets/day(BioThree group) or 9 placebo tablets/day(placebo group)for 12 mo in addition to their ongoing medications.Clinical symptoms were evaluated monthly or on the exacerbation of symptoms or need for additional medication. Fecal samples were collected to analyze bacterial DNA at baseline and 3-mo intervals. Terminal restriction fragment length polymorphism and cluster analyses were done to examine bacterial components of the fecal microflora.RESULTS: Forty-six patients, 23 in each group,completed the study, and 14 were excluded. The relapse rates in the Bio-Three and placebo groups were respectively 0.0% vs 17.4% at 3 mo(P = 0.036), 8.7%vs 26.1% at 6 mo(P = 0.119), and 21.7% vs 34.8%(P = 0.326) at 9 mo. At 12 mo, the remission rate was 69.5% in the Bio-Three group and 56.6% in the placebo group(P = 0.248). On cluster analysis of fecal flora, 7 patients belonged to cluster Ⅰ, 32 to cluster Ⅱ,and 7 to cluster Ⅲ.CONCLUSION: Probiotics may be effective formaintaining clinical remission in patients with quiescent UC, especially those who belong to cluster Ⅰ on fecal bacterial analysis.Yasushi Yoshimatsu Akihiro Yamada Ryuichi Furukawa Koji Sono Aisaku Osamura Kentaro Nakamura Hiroshi Aoki Yukiko Tsuda Nobuo Hosoe Nobuo Takada Yasuo Suzuki 2015World Journal of Gastroenterology2015,21,19:21
7Neoadjuvant chemotherapy for locally advanced cervical cancer显示文摘Neoadjuvant chemotherapy followed by surgery(NCS) has not been fully evaluated clinically. Currently, the main regimen of neoadjuvant chemotherapy(NAC) used in NCS includes cisplatin. The antitumor effects of NAC reduce lymph node metastasis and the tumor diameter in patients prior to surgery, and this can reduce the number of high risk patients who require postoperative radiation therapy. Many randomized controlled trials(RCTs) have examined the long-term prognosis of NCS compared to primary surgery, but the utility of NCS remains uncertain. The advent of concurrent chemoradiotherapy(CCRT) has markedly improved the outcome of radiotherapy(RT), and CCRT is now used as a standard method in many cases of advanced bulky cervical cancer. NCS gives a better treatment outcome than radiation therapy alone, but it is important to verify that NCS gives a similar or better outcome compared to CCRT.Takashi Iwata Azumi Miyauchi Yukako Suga Hiroshi Nishio Masaru Nakamura Akiko Ohno Nobumaru Hirao Tohru Morisada Kyoko Tanaka Hiroki Ueyama Hidemichi Watari Daisuke Aoki 2016Chinese Journal of Cancer Research2016,28,2:20
8Preoperative portal vein embolization for hepatocellular carcinoma: consensus and controversy显示文摘Thirty years have passed since the first report of portal vein embolization(PVE),and this procedure is widely adopted as a preoperative treatment procedure for patients with a small future liver remnant(FLR).PVE has been shown to be useful in patients with hepatocellular carcinoma(HCC)and chronic liver disease.However,special caution is needed when PVE is applied prior to subsequent major hepatic resection in cases with cirrhotic livers,and volumetric analysis of the liver segments in addition to evaluation of the liver functional reserve before PVE is mandatory in such cases.Advances in the embolic material and selection of the treatment approach,and combined use of PVE and transcatheter arterial embolization/chemoembolization have yielded improved outcomes after PVE and major hepatic resections.A novel procedure termed the associating liver partition and portal vein ligation for staged hepatectomy has been gaining attention because of the rapid hypertrophy of the FLR observed in patients undergoing this procedure,however,application of this technique in HCC patients requires special caution,as it has been shown to be associated with a high morbidity and mortality even in cases with essentially healthy livers.Taku Aoki Keiichi Kubota 2016World Journal of Hepatology2016,8,9:19
9Human protamines and the developing spermatid: their structure, function, expression and relationshipwith male infertility显示文摘During spermiogenesis, the protamine proteins play an integral role in spennatid chromatin compaction.Recent research has focused on many facets of protamine biology, including protamine gene and protein structure/function relationships, mechanisms of protamine expression regulation and involvement of the protamines in male fertility. In this paper, we review our current understanding of the structure and function of the protamine-1 (P1) and protamine-2 (P2) proteins and genes, the expression and regulation of these genes and the relationship between the protamines and male fertility. In addition, we offer a brief outlook on future investigation into protamine proteins.Vincent W. Aoki Douglas T. Carrell 2003Asian Journal of Andrology2003,5,4:18
10Sentinel lymph node navigation surgery for early stage gastric cancer显示文摘We attempted to evaluate the history of sentinel node navigation surgery(SNNS),technical aspects,tracers,and clinical applications of SNNS using Infrared Ray Electronic Endoscopes(IREE)combined with Indocyanine Green(ICG).The sentinel lymph node(SLN)is defined as a first lymph node(LN)which receives cancer cells from a primary tumor.Reports on clinical application of SNNS for gastric cancers started to appear since early 2000s.Two prospective multicenter trials of SNNS for gastric cancer have also been accomplished in Japan.Kitagawa et al reported that the endoscopic dual(dye and radioisotope)tracer method for SN biopsy was confirmed acceptable and effective when applied to the early-stage gastric cancer(EGC).We have previously reported the usefulness of SNNS in gastrointestinal cancer using ICG as a tracer,combined with IREE(Olympus Optical,Tokyo,Japan)to detect SLN.LN metastasis rate of EGC is low.Hence,clinical application of SNNS for EGC might lead us to avoid unnecessary LN dissection,which could preserve the patient’s quality of life after operation.The most ideal method of SNNS should allow secure and accurate detection of SLN,and real time observation of lymphatic flow during operation.Norio Mitsumori Hiroshi Nimura Naoto Takahashi Masahiko Kawamura Hiroaki Aoki Atsuo Shida Nobuo Omura Katsuhiko Yanaga 2014World Journal of Gastroenterology2014,20,19:15

12Advanced diffusion magnetic resonance imaging in patients with Alzheimer’s and Parkinson’s diseases显示文摘The prevalence of neurodegenerative diseases is increasing as human longevity increases. The objective biomarkers that enable the staging and early diagnosis of neurodegenerative diseases are eagerly anticipated. It has recently become possible to determine pathological changes in the brain without autopsy with the advancement of diffusion magnetic resonance imaging techniques. Diffusion magnetic resonance imaging is a robust tool used to evaluate brain microstructural complexity and integrity, axonal order, density, and myelination via the micron-scale displacement of water molecules diffusing in tissues. Diffusion tensor imaging, a type of diffusion magnetic resonance imaging technique is widely utilized in clinical and research settings;however, it has several limitations. To overcome these limitations, cutting-edge diffusion magnetic resonance imaging techniques, such as diffusional kurtosis imaging, neurite orientation dispersion and density imaging, and free water imaging, have been recently proposed and applied to evaluate the pathology of neurodegenerative diseases. This review focused on the main applications, findings, and future directions of advanced diffusion magnetic resonance imaging techniques in patients with Alzheimer's and Parkinson's diseases, the first and second most common neurodegenerative diseases, respectively.Koji Kamagata Christina Andica Taku Hatano Takashi Ogawa Haruka Takeshige-Amano Kotaro Ogaki Toshiaki Akashi Akifumi Hagiwara Shohei Fujita Shigeki Aoki 2020Neural Regeneration Research2020,15,9:11
