| 1 | Importance of adequate immunosuppressive therapy for the recovery of patients with 'life-threatening' severe exacerbation of chronic hepatitis B显示文摘AIM: Hepatitis B virus (HBV) re-activation often occurs spontaneously or after withdrawal of immunosuppressive therapy in patients with chronic hepatitis B. Severe exacerbation, sometimes developing into fulminant hepatic failure, is at high risk of mortality. The efficacy of corticosteroid therapy in 'clinically severe' exacerbation of chronic hepatitis B has not been well demonstrated. In this study we evaluated the efficacy of early introduction of high-dose corticosteroid therapy in patients with lifethreatening severe exacerbation of chronic hepatitis B.METHODS: Twenty-two patients, 14 men and 8 women,were defined as 'severe' exacerbation of chronic hepatitis B using uniform criteria and enrolled in this study. Eleven patients were treated with corticosteroids at 60 mg or more daily with or without anti-viral drugs within 10 d after the diagnosis of severe disease ('early high-dose'group) and 11 patients were either treated more than 10 d or untreated with corticosteroids ('non-early high-dose'group).RESULTS: Mean age, male-to-female ratio, mean prothrombin time (PT) activity, alanine transaminase (ALT)level, total bilirubin level, positivity of HBeAg, mean IgMHBc titer, and mean HBV DNA polymerase activity did not differ between the two groups. Ten of 11 patients of the 'early high-dose' group survived, while only 2 of 11 patients of the 'non-early high-dose' group survived (P<0.001). During the first 2 wk after the introduction of corticosteroids, improvements in PT activities and total bilirubin levels were observed in the 'early high-dose'group. Both ALT levels and HBV DNA polymerase levels fell in both groups.CONCLUSION: The introduction of high-dose corticosteroid can reverse deterioration in patients with 'clinically lifethreatening' severe exacerbation of chronic hepatitis B,when used in the early stage of illness. | Keiichi Fujiwara Osamu Yokosuka Hiroshige Kojima Tatsuo Kanda Hiromitsu Saisho Hiroyuki Hirasawa Hiroshi Suzuki | 2005 | World Journal of Gastroenterology2005，11，8： | 20 |
| 2 | Postoperative bleeding in patients on antithrombotic therapy after gastric endoscopic submucosal dissection显示文摘AIM To investigated the relationship between postoperative bleeding following gastric endoscopic submucosal dissection(ESD) and individual antithrombotic agents.METHODS A total of 2488 gastric neoplasms in 2148 consecutive patients treated between May 2001 and June 2016 were studied. The antithrombotic agents were categorized into antiplatelet agents, anticoagulants, and other antithrombotic agents, and we included combination therapies [e.g., dual antiplatelet therapy(DAPT)]. The risk factors associated with post-ESD bleeding, namely, antithrombotic agents overall, individual antithrombotic agents, withdrawal or continuation of antithrombotic agents, and bleeding onset period(during the first six days or thereafter), were analyzed using univariate and multivariate analyses.RESULTS The en bloc resection and complete curative resection rates were 99.2% and 91.9%, respectively. Postoperative bleeding occurred in 5.1% cases. Bleeding occurred in 10.3% of the patients administered antithrombotic agents. Being male(P = 0.007), specimen size(P < 0.001), and antithrombotic agent used(P < 0.001) were independent risk factors for postoperative bleeding. Heparin bridging therapy(HBT)(P = 0.002) and DAPT/multidrug combinations(P < 0.001) were independent risk factors associated with postoperative bleeding. The bleeding rate of the antithrombotic agent continuation group was significantly higher than that of the withdrawal group(P < 0.01). Bleeding within postoperative day(POD) 6 was significantly higher in warfarin(P = 0.015), and bleeding after POD 7 was significantly higher in DAPT/multidrug combinations(P = 0.007). No thromboembolic events were reported.CONCLUSION We must closely monitor patients administered HBT and DAPT/multidrug combinations after gastric ESD, particularly those administered multidrug combinations after discharge. | Chiko Sato Kingo Hirasawa Ryonho Koh Ryosuke Ikeda Takehide Fukuchi Ryosuke Kobayashi Hiroaki Kaneko Makomo Makazu Shin Maeda | 2017 | World Journal of Gastroenterology2017，23，30： | 14 |
| 3 | Blood glucose control in patients with severe sepsis and septic shock显示文摘The main pathophysiological feature of sepsis is the uncontrollable activation of both pro-and anti-inflammatory responses arising from the overwhelming pro-duction of mediators such as pro-and anti-inflammatory cytokines. Such an uncontrollable inflammatory response would cause many kinds of metabolic derangements. One such metabolic derangement is hyperglycemia. Accordingly, control of hyperglycemia in sepsis is considered to be a very effective therapeutic approach. However, despite the initial enthusiasm, recent studies reported that tight glycemic control with intensive insulin therapy failed to show a beneficial effect on mortality of patients with severe sepsis and septic shock. One of the main reasons for this disappointing result is the incidence of harmful hypoglycemia during intensive insulin therapy. Therefore, avoidance of hypoglycemia during intensive insulin therapy may be a key issue in effective tight glycemic control. It is generally accepted that glycemic control aimed at a blood glucose level of 80-100 mg/dL, as initially proposed by van den Berghe, seems to be too tight and that such a level of tight glycemic control puts septic patients at increased risk of hypoglycemia. Therefore, now many researchers suggest less strict glycemic control with a target blood glucose level of 140-180 mg/dL. Also specific targeting of glycemic control in diabetic patients should be considered. Since there is a significantcorrelation between success rate of glycemic control and the degree of hypercytokinemia in septic patients, some countermeasures to hypercytokinemia may be an important aspect of successful glycemic control. Thus, in future, use of an artificial pancreas to avoid hypoglycemia during insulin therapy, special consideration of septic diabetic patients, and control of hypercytokinemia should be considered for more effective glycemic control in patients with severe sepsis and septic shock. | Hiroyuki Hirasawa Shigeto Oda Masataka Nakamura | 2009 | World Journal of Gastroenterology2009，15，33： | 13 |

| 5 | Successful initial ablation therapy contributes to survival in patients with hepatocellular carcinoma显示文摘AIM: To evaluate the outcome predictors of percu- taneous ablation therapy in patients with unresectable hepatocellular carcinoma (HCC), especially to identify whether the initial treatment response contributes to the survival of the patients. METHODS: The study cohort included 153 patients with single (102) and two or three (51) HCC nodules 5 cm or less in maximum diameter. As an initial treatment, 110 patients received radiofrequency ablation and 43 patients received percutaneous ethanol injection. RESULTS: The Kaplan-Meier estimates of overall 3- and 5-year survival rates were 75% and 59%, respectively. The log-rank test revealed statistically significant differences in the overall survivals according to Child- Pugh class (P = 0.0275), tumor size (P = 0.0130), serum albumin level (P = 0.0060), serum protein induced by vitamin K absence or antagonist Ⅱ level (P = 0.0486), and initial treatment response (P = 0.0130). The independent predictors of survival were serum albumin level (risk ratio, 3.216; 95% CI, 1.407-7.353; P = 0.0056) and initial treatment response (risk ratio, 2.474; 95% CI, 1.076-5.692; P = 0.0330) based on the Cox proportional hazards regression models. The patients had a serum albumin level 3.5 g/dL and the 3- and 5-year survival rates of 86% and 82%. CONCLUSION: In HCC patients treated with percutaneous ablation therapy, serum albumin level and initial treatment response are the independent outcome predictors. | Manabu Morimoto Kazushi Numata Kazuya Sugimori Kazuhito Shirato Atsushi Kokawa Hiroyuki Oka Kingo Hirasawa Ryonho Koh Hiromi Nihommatsu Katsuaki Tanaka | 2007 | World Journal of Gastroenterology2007，13，7： | 8 |
| 6 | Coagulation syndrome: Delayed perforation after colorectal endoscopic treatments显示文摘Various procedure-related adverse events related to colonoscopic treatment have been reported. Previous studies on the complications of colonoscopic treatment have focused primarily on perforation or bleeding. Coagulation syndrome(CS), which is synonymous with transmural burn syndrome following endoscopic treatment, is another typical adverse event. CS is the result of electrocoagulation injury to the bowel wall that induces a transmural burn and localized peritonitis resulting in serosal inflammation. CS occurs after polypectomy, endoscopic mucosal resection(EMR), and even endoscopic submucosal dissection(ESD). The occurrence of CS after polypectomy or EMR varies according previous reports; most report an occurrence rate around 1%. However, artificial ulcers after ESD are largely theoretical, and CS following ESD was reported in about 9% of cases, which is higher than that for CS after polypectomy or EMR. Most cases of post-polypectomy syndrome(PPS) have an excellent prognosis, and they are managed conservatively with medical therapy. PPS rarely develops into delayed perforation. Delayed perforation is a severe adverse event that often requires emergency surgery. Since few studies have reported on CS and delayed perforation associated with CS, we focused on CS after colonoscopic treatments in this review. Clinicians should consider delayed perforation in CS patients. | Kingo Hirasawa Chiko Sato Makomo Makazu Hiroaki Kaneko Ryosuke Kobayashi Atsushi Kokawa Shin Maeda | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，12： | 7 |
| 7 | Clinicopathological features of early gastric cancers arising in Helicobacter pylori uninfected patients显示文摘BACKGROUND Persistent Helicobacter pylori(H.pylori)infection causes chronic inflammation,atrophy of the gastric mucosa,and a high risk of developing gastric cancer.In recent years,awareness of eradication therapy has increased in Japan.As H.pylori infections decrease,the proportion of gastric cancers arising from H.pylori uninfected gastric mucosa will increase.The emergence of gastric cancer arising in H.pylori uninfected patients though rarely reported,is a concern to be addressed and needs elucidation of its clinicopathological features.AIM To evaluate the clinicopathological features of early gastric cancer in H.pyloriuninfected patients.METHODS A total of 2462 patients with 3375 instances of early gastric cancers that were treated by endoscopic submucosal dissection were enrolled in our study between May 2000 and September 2019.Of these,30 lesions in 30 patients were diagnosed as H.pylori-uninfected gastric cancer(Hp UIGC).We defined a patient as H.pylori-uninfected using the following three criteria:(1)The patient did not receive treatment for H.pylori,which was determined by investigating medical recordsand conducting patient interviews;(2)Lack of endoscopic atrophy;and(3)The patient was negative for H.pylori after being tested at least twice using various diagnostic methods,including serum anti-H.pylori-Ig G antibody,urease breath test,rapid urease test,and microscopic examination.RESULTS The frequency of Hp UIGC was 1.2%(30/2462)for the patients in our study.The study included 19 males and 11 females with a mean age of 59 years.The location of the stomach lesions was divided into three sections;upper third(U),middle third(M),lower third(L).Of the 30 lesions,15 were U,1 was M,and 14 were L.Morphologically,17 lesions were protruded and flat elevated type(0-I,0-IIa,0-IIa+IIc),and 13 lesions were flat and depressed type(0-IIb,0-IIc).The median tumor diameter was 8 mm(range 2-98 mm).Histological analysis revealed that22 lesions(73.3%)were differentiated type.The Hp UIGC lesions were classified into fundic gland type adenocarcinoma(7 cases),foveolar type welldifferentiated adenocarcinoma(8 cases),intestinal phenotype adenocarcinoma(7 cases),and pure signet-ring cell carcinoma(8 cases).Among 30 Hp UIGCs,24 lesions(80%)were limited to the mucosa;wherein,the remaining 6 lesions showed submucosal invasion.One of the submucosal invasive lesions showed more than 500μm invasion.The mucin phenotype analysis identified 7 Hp UIGC with intestinal phenotype and 23 with gastric phenotype.CONCLUSION We elucidated the clinicopathological characteristics of Hp UIGC,revealing recognition not only undifferentiated-type but also differentiated-type.In addition,intestinal phenotype tumors were also observed and could be an important tip. | Chiko Sato Kingo Hirasawa Yoko Tateishi Yuichiro Ozeki Atsushi Sawada Ryosuke Ikeda Takehide Fukuchi Masafumi Nishio Ryosuke Kobayashi Makomo Makazu Hiroaki Kaneko Yoshiaki Inayama Shin Maeda | 2020 | World Journal of Gastroenterology2020，26，20： | 7 |

| 10 | Histopathological validation of magnifying endoscopy for diagnosis of mixed-histological-type early gastric cancer显示文摘BACKGROUND The undifferentiated-type(UDT)component profoundly affects the clinical course of early gastric cancers(EGCs).However,an accurate preoperative diagnosis of the histological types is unsatisfactory.To date,few studies have investigated whether the UDT component within mixed-histological-type(MT)EGCs can be recognized preoperatively.AIM To clarify the histopathological characteristics of the endoscopically-resected MT EGCs for investigating whether the UDT component could be recognized preoperatively.METHODS This was a single-center retrospective study.First,we attempted to clarify the histopathological characteristics of the endoscopically-resected MT EGCs with emphasis on the UDT component.Histopathological examination investigated each lesion’s UDT component:(1)Whole mucosal layer occupation of the UDT component;(2)UDT component exposure to the surface of the mucosa;and(3)existence of a clear border between the differentiated-type and UDT components.Then,preoperative endoscopic images with magnifying endoscopy with narrowband imaging(ME-NBI)were examined to identify whether the endoscopic UDT component finding was recognizable within the area where it was present in the histopathological examination.The preoperative biopsy results and comparative relationships between endoscopic and histopathological findings were also examined.RESULTS In the histopathological examination,the whole mucosal layer occupation of the UDT component and exposure of the UDT component to the mucosal surface were observed in 67.3%(33/49)and 79.6%(39/49)of samples,respectively.A clear distinction of the border between the differentiated-type and UDT components could not be drawn in 65.3%(32/49)of MT lesions.In the endoscopic examination,the preoperative endoscopic images showed that only 24.5%(12/49)of MT EGCs revealed the UDT component within the area where it was present histopathologically.Histopathological UDT predominance was the single significant factor associated with the presence of the endoscopic UDT component finding(61.5%vs 11.1%,P=0.0009).Only 26.5%(13/49)of the lesions were diagnosed from the pretreatment biopsy as having a UDT component.Combined results of the pretreatment biopsy and ME-NBI showed the preoperative presence of the UDT component in 40.8%(20/49)of MT EGCs.CONCLUSION Recognition of a UDT component within MT EGCs is difficult even when pretreatment biopsy and ME-NBI are combined.Endoscopic resection plays a significant role in both treatment and diagnosis. | Yuichiro Ozeki Kingo Hirasawa Ryosuke Kobayashi Chiko Sato Yoko Tateishi Atsushi Sawada Ryosuke Ikeda Masafumi Nishio Takehide Fukuchi Makomo Makazu Masataka Taguri Shin Maeda | 2020 | World Journal of Gastroenterology2020，26，36： | 5 |
| 11 | Comparison of corneal biomechanical properties in normal tension glaucoma patients with different visual field progression speed显示文摘AIM:To compare the corneal biomechanical properties difference by ocular response analyzer(ORA) in normal tension glaucoma(NTG) patients with different visual field(VF) progression speed. METHODS:NTG patients with well-controlled Goldmann applanation tonometer(GAT) who routinely consulted Kitasato University Hospital Glaucoma Department between January 2010 and February 2014 were enrolled.GAT and ORA parameters including corneal compensated intraocular pressure(lOPcc),Goldmann estimated intraocular pressure(lOPg),corneal hysteresis(CH),corneal resistance factor(CRF) were recorded.VF was tested by Swedish interactive threshold algorithm(SITA)-standard 30-2 fields.All patients underwent VF measurement regularly and GAT did not exceed 15 mm Hg at any time during the 3y follow up.Patients were divided into four groups according to VF change over 3y,and ORA findings were compared between the upper 25^(th) percentile group(slow progression group) and the lower 25^(th) percentile group(rapid progression group).RESULTS:Eighty-two eyes of 56 patients were studied.There were 21 eyes(21 patients) each in rapid and slow progression groups respectively.GAT,lOPcc,lOPg,CH,CRF were 12.1+1.4 mm Hg,15.8±1.8 mm Hg,12.8±2.0 mm Hg,8.4±1.1 mm Hg,7.9±1.3 mm Hg respectively in rapid progression group and 11.5±1.3 mm Hg,13.5±2.1 mm Hg,11.2±1.6 mm Hg,9.3±1.1 mm Hg,8.2±0.9 mm Hg respectively in slow progression group(P=0.214,<0.001,0.007,0.017,0.413,respectively).In bivariate correlation analysis,lOPcc,lOPcc-GAT and CH were significant correlated with m△MD(r =-0.292,-0.312,0.228 respectively,P =0.008,0.004,0.039 respectively).CONCLUSION:Relatively rapid VF progression occurred in NTG patients whose lOPcc are rather high,CH are rather low and the difference between lOPcc and GAT are relatively large.Higher lOPcc and lower CH are associated with VF progression in NTG patients.This study suggests that GAT measures might underestimate the IOP in such patients. | Ying Hong Nobuyuki Shoji Tetsuya Morita Kazunori Hirasawa Kazuhiro Matsumura Masayuki Kasahara Kimiya Shimizu | 2016 | International Journal of Ophthalmology(English edition)2016，9，7： | 4 |

| 13 | 厚板镦粗-翻边复合工艺(英文)显示文摘传统圆孔翻边工艺中,翻边高度和形状精度是制约板料成形极限的主要因素。为了获得较为稳固的翻边凸起部位,提出采用镦粗-翻边复合工艺成形厚板翻边凸起结构。利用DEFORM有限元软件对镦粗-翻边复合工艺过程进行数值模拟,分析各工艺参数对翻边高度的影响规律;对A1050P-O厚板进行了镦粗-翻边工艺试验并讨论了翻边后的板料硬度分布规律。结果表明:与传统翻边工艺相比,镦粗-翻边工艺的翻边凸起部位精度更好、翻边高度更高,且有限元模拟结果与试验结果保持了较好的一致性。成形后的板料由于加工硬化影响,翻边凸起结构的硬度增大,有利于零件的后续加工组装工序。 | 林启权 董文正 王志刚 Katsuyoshi HIRASAWA | 2014 | Transactions of Nonferrous Metals Society of China2014，24，7： | 3 |
| 14 | Carbon dioxide insufflation in esophageal endoscopic submucosal dissection reduces mediastinal emphysema: A randomized, double-blind, controlled trial显示文摘AIM To assess the efficacy of CO2 insufflation for reduction of mediastinal emphysema(ME) immediately after endoscopic submucosal dissection(ESD).METHODS A total of 46 patients who were to undergo esophageal ESD were randomly assigned to receive either CO2 insufflation(CO2 group, n = 24) or air insufflation(Air group, n = 22). Computed tomography(CT) was carried out immediately after ESD and the next morning. Pain and abdominal distention were chronologically recorded using a 100-mm visual analogue scale(VAS). The volume of residual gas in the digestive tract was measured using CT imaging. RESULTS The incidence of ME immediately after ESD in the CO2 group was significantly lower than that in the Air group(17% vs 55%, P = 0.012). The incidence of ME the next morning was 8.3% vs 32% respectively(P= 0.066). There were no differences in pain scores or distention scores at any post-procedure time points. The volume of residual gas in the digestive tract immediately after ESD was significantly smaller in the CO2 group than that in the Air group(808 m L vs 1173 m L, P = 0.013).CONCLUSION CO2 insufflation during esophageal ESD significantly reduced postprocedural ME. CO2 insufflation also reduced the volume of residual gas in the digestive tract immediately after ESD, but not the VAS scores of pain and distention. | Yuki Maeda Dai Hirasawa Naotaka Fujita Tetsuya Ohira Yoshihiro Harada Taku Yamagata Yoshiki Koike Kenjirou Suzuki | 2016 | World Journal of Gastroenterology2016，22，32： | 3 |

| 18 | Atmospheric River Signatures in Radiosonde Profiles and Reanalyses at the Dronning Maud Land Coast,East Antarctica显示文摘Atmospheric rivers(ARs)are an important component of the hydrological cycle linking moisture sources in lower latitudes to the Antarctic surface mass balance.We investigate AR signatures in the atmospheric vertical profiles at the Dronning Maud Land coast,East Antarctica,using regular and extra radiosonde measurements conducted during the Year of Polar Prediction Special Observing Period November 2018 to February 2019.Prominent AR events affecting the locations of Neumayer and Syowa cause a strong increase in specific humidity extending through the mid-troposphere and a strong low-level jet(LLJ).At Neumayer,the peak in the moisture inversion(up to 4 g kg^?1)is observed between 800 and 900 hPa,while the LLJ(up to 32 m s^?1)is concentrated below 900 hPa.At Syowa the increase in humidity is less pronounced and peaks near the surface,while there is a substantial increase in wind speed(up to 40 m s?1)between 825 and 925 hPa.Moisture transport(MT)within the vertical profile during the ARs attains a maximum of 100 g kg?1 m s?1 at both locations,and is captured by both ERA-Interim and ERA5 reanalysis data at Neumayer,but is strongly underestimated at Syowa.Composites of the enhanced MT events during 2009?19 show that these events represent an extreme state of the lower-tropospheric profile compared to its median values with respect to temperature,humidity,wind speed and,consequently,MT.High temporal-and vertical-resolution radiosonde observations are important for understanding the contribution of these rare events to the total MT towards Antarctica and improving their representation in models. | Irina V.GORODETSKAYA Tiago SILVA Holger SCHMITHUSEN Naohiko HIRASAWA | 2020 | Advances in Atmospheric Sciences2020，37，5： | 2 |
