| 1 | Nonalcoholic fatty liver disease is a novel predictor of cardiovascular disease显示文摘AIM:To clarify whether nonalcoholic fatty liver disease(NAFLD)increases the risk of cardiovascular disease.METHODS:We carried out a prospective observational study with a total of 1637 apparently healthy Japanese men and women who were recruited from a health check-up program.NAFLD was diagnosed by abdominal ultrasonography.The metabolic syndrome(MS)was defined according to the modified National Cholesterol Education Program(NCEP)ATP Ⅲ criteria.Five years after the baseline evaluations,the incidence of cardiovascular disease was assessed by a self-administered questionnaire.RESULTS:Among 1221 participants available for outcome analyses,the incidence of cardiovascular disease was higher in 231 subjects with NAFLD at baseline(5 coronary heart disease,6 ischemic stroke,and 1 cerebral hemorrhage)than 990 subjects without NAFLD(3 coronary heart disease,6 ischemic stroke,and 1 cerebral hemorrhage).Multivariate analyses indicated that NAFLD was a predictor of cardiovascular disease independent of conventional risk factors(odds ratio 4.12,95% CI,1.58 to 10.75,P = 0.004).MS was alsoindependently associated with cardiovascular events.But simultaneous inclusion of NAFLD and MS in a multivariate model revealed that NAFLD but not MS retained a statistically significant correlation with cardiovascular disease.CONCLUSION:Although both of them were predictors of cardiovascular disease,NAFLD but not MS retained a statistically significant correlation with cardiovascular disease in a multivariate model.NAFLD is a strong predictor of cardiovascular disease and may play a central role in the cardiovascular risk of MS. | Masahide Hamaguchi Takao Kojima Noriyuki Takeda Chisato Nagata Jun Takeda Hiroshi Sarui Yutaka Kawahito Naohisa Yoshida Atsushi Suetsugu Takahiro Kato Junichi Okuda Kazunori Ida Toshikazu Yoshikawa | 2007 | World Journal of Gastroenterology2007，13，10： | 55 |
| 2 | 长江口沉积物^(210)Pb分布及沉积环境解释显示文摘在长江河口潮滩、分流河道和水下三角洲共获得18个柱样,进行沉积学分析和210Pb测定,并对其中6根柱样进行137Cs测定。经研究发现,长江口外在水深25~30m,122°30′N,31°00′E附近存在一个泥质沉积中心,沉积速率达2.0~6.3cm/yr。另外,在潮滩和涨潮槽也获得较高沉积速率,其中南汇和横沙岛潮滩沉积速率(1.03~1.94cm/yr)高于崇明东滩(0.51~0.76cm/yr),涨潮槽沉积速率也达0.86cm/yr。此外,在石洞口、南汇、九段沙潮滩和三角洲前缘有部分柱样未获沉积速率,推测为沉积环境不稳定或沉积速率过快所致。 | 段凌云 王张华 李茂田 潘建明 陈中原 Yishiki Saito Yutaka kanai | 2005 | 沉积学报2005，23，3： | 47 |
| 3 | Current status and future strategies of cytoreductive surgery plus intraperitoneal hyperthermic chemotherapy for peritoneal carcinomatosis显示文摘This article is to offer a concise review on the use of cytoreductive surgery (CRS) plus intraperitoneal hyperthermic chemotherapy (IPHC) for the treatment of peritoneal carcinomatosis (PC). Traditionally, PC was treated with systemic chemotherapy alone with very poor response and a median survival of less than 6 mo. With the establishment of several phase Ⅱ studies, a new trend has been developed toward the use of CRS plus IPHC as a standard method for treating selected patients with PC, in whom sufficient cytoreduction could be achieved. In spite of the need for more high quality phase Ⅲ studies, there is now a consensus among many surgical oncology experts throughout the world about the use of this new treatment strategy as standard care for colorectal cancer patients with PC. This review summarizes the current status and possible progress in future. | Hassan Alaa Hammed al-Shammaa Yan Li Yutaka Yonemura | 2008 | World Journal of Gastroenterology2008，14，8： | 50 |

| 5 | Shear wave velocity is a useful marker for managing nonalcoholic steatohepatitis显示文摘AIM:To investigate whether a noninvasive measurement of tissue strain has a potential usefulness for management of nonalcoholic steatohepatitis(NASH).METHODS:In total 26 patients,23 NASHs and 3 normal controls were enrolled in this study.NASH was staged based on Brunt criterion.At a region of interest(ROI),a shear wave was evoked by implementing an acoustic radiation force impulse(ARFI),and the propagation velocity was quantif ied.RESULTS:Shear wave velocity(SWV) could be reproducibly quantified at all ROIs in all subjects except for 4 NASH cases,in which a reliable SWV value was not calculated at several ROIs.An average SWV of 1.34 ± 0.26 m/s in fibrous stage 0-1 was significantly slower than 2.20 ± 0.74 m/s and 2.90 ± 1.01 m/s in stages 3 and 4,respectively,but was not significantly different from 1.79 ± 0.78 m/s in stage 2.When a cutoff value was set at 1.47 m/s,receiver operating characteristic analysis showed significance to dissociate stages 3 and 4 from stage 0-1(P=0.0092) with sensitivity,specificity and area under curve of 100%,75% and 94.2%,respectively.In addition,the correlation between SWV and hyaluronic acid was significant(P<0.0001),while a tendency toward negative correlation was observed with serum albumin(P=0.053).CONCLUSION:The clinical implementation of ARFI provides noninvasive repeated evaluations of liver stiffness at an arbitrary position,which has the potential to shed new light on NASH management. | Akihiko Osaki Tomoyuki Kubota Takeshi Suda Masato Igarashi Keisuke Nagasaki Atsunori Tsuchiya Masahiko Yano Yasushi Tamura Masaaki Takamura Hirokazu Kawai Satoshi Yamagiwa Toru Kikuchi Minoru Nomoto Yutaka Aoyagi | 2010 | World Journal of Gastroenterology2010，16，23： | 30 |
| 6 | Multidisciplinary therapy for treatment of patients with peritoneal carcinomatosis from gastric cancer显示文摘There is no standard treatment for peritoneal carcinomatosis (PC) from gastric cancer.A novel multidisciplinary treatment combining bidirectional chemotherapy [neoadjuvant intraperitoneal-systemic chemotherapy protocol (NIPS)],peritonectomy,hyperthermic intraperitoneal chemoperfusion (HIPEC) and early postoperative intraperitoneal chemotherapy has been developed.In this article,we assess the indications,safety and eff icacy of this treatment,review the relevant studies and introduce our experiences.The aims of NIPS are stage reduction,the eradication of peritoneal free cancer cells,and an increased incidence of complete cytoreduction (CC-0) for PC.A complete response after NIPS was ob-tained in 15 (50%) out of 30 patients with PC.Thus,a signif icantly high incidence of CC-0 can be obtained in patients with a peritoneal cancer index (PCI) ≤ 6.Using a multivariate analysis to examine the survival benef it,CC-0 and NIPS are identified as significant indicators of a good outcome.However,the high morbidity and mortality rates associated with peritonectomy and perioperative chemotherapy make stringent patient selection important.The best indications for multidisciplinary therapy are localized PC (PCI≤6) from resectable gastric cancer that can be completely removed during a peritonectomy.NIPS and complete cytoreduction are essential treatment modalities for improving the survival of patients with PC from gastric cancer. | Yutaka Yonemura Ayman Elnemr Yoshio Endou Mitsumasa Hirano Akiyoshi Mizumoto Nobuyuki Takao Masumi Ichinose Masahiro Miura | 2010 | World Journal of Gastrointestinal Oncology2010，2，2： | 27 |
| 7 | 膜采样离线分析与在线测定大气细粒子中元素碳和有机碳的比较显示文摘针对普遍采用的膜采样离线分析与在线测定大气细粒子中元素碳和有机碳的方法进行了比较分析.2006年1月--2007年4月期间在北京大学校园内应用膜采样离线分析和在线分析分季节同时测定了PM2.5中元素碳(EC)和有机碳(OC),并将结果进行对比.结果显示,膜采样法测得的OC约为在线仪器测得的OC的2倍,2种方法差别主要体现在对OC的测量上.不加平行板有机物扩散吸收管引入OC比较大的正误差,而加平行板有机物扩散吸收管又将引入OC的负误差,约10%.同时采用平行板有机物扩散吸收管和后置膜的离线分析方法同在线观测的结果具有比较好的一致性. | 胡敏 邓志强 王轶 林鹏 曾立民 Yutaka Kondo ZHAO Yong-jing | 2008 | 环境科学2008，29，12： | 27 |
| 8 | Narrow-band imaging optical chromocolonoscopy: Advantages and limitations显示文摘Narrow-band imaging (NBI) is an innovative optical technology that modifies the center wavelength and bandwidth of an endoscope’s light into narrow-band illumination of 415 ± 30 nm. NBI markedly improves capillary pattern contrast and is an in vivo method for visualizing microvessel morphological changes in superficial neoplastic lesions. The scientific basis for NBI is that short wavelength light falls within the hemoglobin absorption band, thereby facilitating clearer visualization of vascular structures. Several studies have reported advantages and limitations of NBI colonoscopy in the colorectum. One difficulty in evaluating results, however, has been non-standardization of NBI systems (Sequential and non-sequential). Utilization of NBI technology has been increasing worldwide, but accurate pit pattern analysis and suffi cient skill in magnifying colonoscopy are basic fundamentals required for profi ciency in NBI diagnosis of colorectal lesions. Modern optical technology without proper image interpretation wastes resources, confuses untrained endoscopists and delays inter-institutional validation studies. Training in the principles of 'optical image-enhanced endoscopy' is needed to close the gap between technological advancements and their clinical usefulness. Currently available evidence indicates that NBI constitutes an effective and reliable alternative to chromocolonoscopy forin vivo visualization of vascular structures, but further study assessing reproducibility and effectiveness in the colorectum is ongoing at various medical centers. | Fabian Emura Yutaka Saito Hiroaki Ikematsu | 2008 | World Journal of Gastroenterology2008，14，31： | 25 |

| 10 | Assessment 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 | 2012 | World Journal of Gastroenterology2012，18，28： | 22 |
| 11 | 为早食道、胃的癌症的诊断的内视镜的超声使用超声探针显示文摘 Endoscopic ultrasound(EUS) devices were first designed and manufactured more than 30 years ago,and since then investigators have reported EUS is effective for determining both the staging and the depth of invasion of esophageal and gastric cancers.We review the present status,the methods,and the findings of EUS when used to diagnose and stage early esophageal and gastric cancer.EUS using high-frequency ultrasound probes is more accurate than conventional EUS for the evaluation of the depth of invasion of superficial esophageal carcinoma.The rates of accurate evaluation of the depth of invasion by EUS using high-frequency ultrasound probes were 70%-88% for intramucosal cancer,and 83%-94% for submucosal invasive cancer.But the sensitivity of EUS using high-frequency ultrasound probes for the diagnosis of submucosal invasive cancer was relatively low,making it difficult to confirm minute submucosal invasion.The accuracy of EUS using highfrequency ultrasound probes for early gastric tumor classification can be up to 80% compared with 63% for conventional EUS,although the accuracy of EUS using high-frequency ultrasound probes relatively decreases for those patients with depressed-type lesions,undifferentiated cancer,concomitant ulceration,expanded indications,type 0-Ⅰ lesions,and lesions located in the upper-third of the stomach.A 92% overall accuracy rate was achieved when both the endoscopic appearance and the findings from EUS using high-frequency ultrasound probes were considered together for tumor classification.Although EUS using high-frequency ultrasound probes has limitations,it has a high depth of invasion accuracy and is a useful procedure to distinguish lesions in the esophagus and stomach that are indicated for endoscopic resection. | Shigetaka Yoshinaga Ichiro Oda Satoru Nonaka Ryoji Kushima Yutaka Saito | 2012 | World Journal of Gastrointestinal Endoscopy2012，4，6： | 21 |
| 12 | Noninvasive estimation of liver fibrosis and response to interferon therapy by a serum fibrogenesis marker, YKL-40, in patients with HCV-associated liver disease显示文摘AIM: To evaluate the clinical utility of serum fibrosis markers,including YKL-40, in patients with HCV-associated liver disease.METHODS: A total of 109 patients with HCV-associated liver disease were enrolled. We measured serum type Ⅳ collagen, amino-terminal peptide of type Ⅲ procollagen (PⅢP),hyaluronic acid (HA), YKL-40 levels and biochemical.Parameters by RIA or ELISA. Eighty-eight patients underwent liver biopsy, and 67 of 109 patients received interferon (IFN)therapy. We also investigated the relationship between the concentrations of serum fibrosis markers and histological fibrosis scores (METAVIR), and evaluated the changes of the levels of fibrosis markers before and after the IFN therapy.RESULTS: The increase in serum levels of all markers,particularly HA, was correlated with the progression of liver fibrosis (for type Ⅳ collagen, F= 9.076, P<0.0001; for PⅢP,F= 9.636, P<0.0001; for HA, F= 13.128, P<0.0001; and for YKL-40, F= 8.016, P<0.0001). YKL-40 had strong correlation with HA (r= 0.536, P<0.0001). Based on the receiver operating curve (ROC), the ability of serum HA exceeded the abilities of other serum markers to determine fibrosis score 4 from fibrosis score 0-3 (AUC = 0.854). While YKL-40 was superior to other fibrosis markers for predicting severe fibrosis (F2-F4) from mild fibrosis (F0-F1) (YKL-40, AUC = 0.809;HA, AUC = 0.805). After IFN therapy, only YKL-40 values significantly decreased not only in the responder group,but also in the nonresponder group (P = 0.03).CONCLUSION: YKL-40 may be a useful non-invasive serum marker to estimate the degree of liver fibrosis and to evaluate the efficacy of IFN therapies in patients with HCV-associated liver disease. | Yukiko Saitou Katsuya Shiraki Yutaka Yamanaka Yumi Yamaguchi Tomoyuki Kawakita Norihiko Yamamoto Kazushi Sugimoto Kazumoto Murata Takeshi Nakano | 2005 | World Journal of Gastroenterology2005，11，4： | 21 |
| 13 | Management and associated factors of delayed perforation after gastric endoscopic submucosal dissection显示文摘AIM: To identify the actual clinical management and associated factors of delayed perforation after gastric endoscopic submucosal dissection(ESD).METHODS: A total of 4943 early gastric cancer(EGC) patients underwent ESD at our hospital between January 1999 and June 2012. We retrospectively assessed the actual management of delayed perforation. In addition, to determine the factors associated with delayed perforation, after excluding 123 EGC patients with perforations that occurred during the ESD procedure, we analyzed the following clinicopathological factors among the remaining 4820 EGC patients by comparing the ESD cases with delayed perforation and the ESD cases without perforation: age, sex, chronological periods, clinical indications for ESD, status of the stomach, location, gastric circumference, tumor size, invasion depth, presence/absence of ulceration, histological type, type of resection, and procedure time.RESULTS: Delayed perforation occurred in 7(0.1%) cases. The median time until the occurrence of delayed perforation was 11 h(range, 6-172 h). Three(43%) of the 7 cases required emergency surgery, while four were conservatively managed without surgical intervention. Among the 4 cases with conservative management, 2 were successfully managed endoscopically using the endoloop-endoclip technique. The median hospital stay was 18 d(range, 15-45 d). There were no delayed perforation-related deaths. Based on a multivariate analysis, gastric tube cases(OR = 11.0; 95%CI: 1.7-73.3; P = 0.013) were significantly associated with delayed perforation.CONCLUSION: Endoscopists must be aware of not only the identified factors associated with delayed perforation, but also how to treat this complicationeffectively and promptly. | Haruhisa Suzuki Ichiro Oda Masau Sekiguchi Seiichiro Abe Satoru Nonaka Shigetaka Yoshinaga Takeshi Nakajima Yutaka Saito | 2015 | World Journal of Gastroenterology2015，21，44： | 21 |
| 14 | Diagnostic and therapeutic single-operator cholangiopancreatoscopy in biliopancreatic diseases:Prospective multicenter study in Japan显示文摘AIM: To assess the utility and safety of single-operator cholangiopancreatoscopy(SOCPS) using the Spy Glass system in widespread clinical application for biliary and pancreatic diseases.METHODS: This study was a prospective case series conducted in 20 referral centers in Japan. There were 148 patients who underwent SOCPS; 124 for biliary diseases and 24 for pancreatic diseases. The attempted interventions were SOCPS examination, SOCPS-directed tissue sampling, and therapy for stone removal, among others. The main outcomes were related to the procedure success rate in terms of visualizing the target lesions, SOCPS-directed adequate tissue sampling, and complete stone removal. RESULTS: A total of 148 patients were enrolled for the diagnosis of indeterminate biliary and pancreatic lesions or treatment of biliary and pancreatic disease. The overall procedure success rate of visualizing the target lesions was 91.2%(135/148). The overall procedural success rates of visualizing the target lesions of diagnostic SOCPS in the bile duct and pancreatic duct were 95.5%(84/89) and 88.2%(15/17), respectively. Diagnosis: the overall adequate tissue for histologic examination was secured in 81.4% of the 86 patients who underwent biopsy under SOCPS(bile duct, 60/75, 80.0%; pancreatic duct, 10/11, 90.9%). The accuracy of histologic diagnosis using SOCPS-directed biopsies in indeterminate bile duct lesions was 70.7%(53/75). In the pancreatic duct, the accuracy of SOCPS visual impression of intraductal papillary mucinous neoplasm was 87.5%(14/16). Stone therapy: complete biliary and pancreatic stone clearance combined with SOCPS-directed stone therapy using electrohydraulic lithotripsy or laser lithotripsy was achieved in 74.2%(23/31) and 42.9%(3/7) of the patients, respectively. Others: SOCPS using the Spy Glass system was used in cannulation of the cystic duct in two patients and for passing across the obstructed self-expandable metallic stent for a malignant biliary stricture in two patients. All procedures were successful in both SOCPS-guided therapies. The incidence of procedure-related adverse events was 5.4%(8/148). CONCLUSION: SOCPS with direct visualization and biopsy for diagnosis and SOCPS-directed therapy for biliary and pancreatic diseases can be safely performed with a high success rate. | Toshio Kurihara Ichiro Yasuda Hiroyuki Isayama Toshio Tsuyuguchi Taketo Yamaguchi Ken Kawabe Yoshinobu Okabe Keiji Hanada Tsuyoshi Hayashi Takao Ohtsuka Syuhei Oana Hiroshi Kawakami Yoshinori Igarashi Kazuya Matsumoto Kiichi Tamada Shomei Ryozawa Hiroki Kawashima Yutaka Okamoto Iruru Maetani Hiroyuki Inoue Takao Itoi | 2016 | World Journal of Gastroenterology2016，22，5： | 20 |
| 15 | Removal of diminutive colorectal polyps: A prospective randomized clinical trial between cold snare polypectomy and hot forceps biopsy显示文摘AIM To compare the efficacy and safety of cold snare polypectomy(CSP) and hot forceps biopsy(HFB) for diminutive colorectal polyps.METHODS This prospective, randomized single-center clinical trial included consecutive patients ≥ 20 years of age with diminutive colorectal polyps 3-5 mm from December 2014 to October 2015. The primary outcome measures were en-bloc resection(endoscopic evaluation) and complete resection rates(pathological evaluation). The secondary outcome measures were the immediate bleeding or immediate perforation rate after polypectomy, delayed bleeding or delayed perforation rate after polypectomy, use of clipping for bleeding or perforation, and polyp retrieval rate. Prophylactic clipping after polyp removal wasn't routinely performed.RESULTS Two hundred eight patients were randomized into the CSP(102), HFB(106) and 283 polyps were evaluated(CSP: 148, HFB: 135). The en-bloc resection rate was significantly higher with CSP than with HFB [99.3%(147/148) vs 80.0%(108/135), P < 0.0001]. The complete resection rate was significantly higher with CSP than with HFB [80.4%(119/148) vs 47.4%(64/135), P < 0.0001]. The immediate bleeding rate was similar between the groups [8.6%(13/148) vs 8.1%(11/135), P = 1.000], and endoscopic hemostasis with hemoclips was successful in all cases. No cases of perforation or delayed bleeding occurred. The rate of severe tissue injury to the pathological specimen was higher HFB than CSP [52.6%(71/135) vs 1.3%(2/148), P < 0.0001]. Polyp retrieval failure was encountered CSP(7), HFB(2).CONCLUSION CSP is more effective than HFB for resecting diminutive polyps. Further long-term follow-up study is required. | Yoriaki Komeda Hiroshi Kashida Toshiharu Sakurai George Tribonias Kazuki Okamoto Masashi Kono Mitsunari Yamada Teppei Adachi Hiromasa Mine Tomoyuki Nagai Yutaka Asakuma Satoru Hagiwara Shigenaga Matsui Tomohiro Watanabe Masayuki Kitano Takaaki Chikugo Yasutaka Chiba Masatoshi Kudo | 2017 | World Journal of Gastroenterology2017，23，2： | 20 |
| 16 | Short term results of endoscopic submucosal dissection in superficial esophageal squamous cell neoplasms显示文摘AIM: To evaluate the efficacy of endoscopic submucosal dissection for superficial esophageal squamous cell neoplasms. METHODS: Between July 2007 and March 2009, 27 consecutive superficial esophageal squamous cell neoplasms in 25 enrolled patients were treated by endoscopic submucosal dissection. The therapeutic efficacy, complications, and follow-up results were assessed. RESULTS: The mean size of the lesions was 21 ± 13 mm (range 2-55 mm); the mean size of the resection specimens was 32 ± 12 mm (range 10-70 mm). The enblock resection rate was 100% (27/27), and en block resection with tumor-free lateral/basal margins was 88.9% (24/27). Perforation occurred in 1 patient who was managed by conservative medical treatments. None of the patients developed local recurrence or distant metastasis in the follow-up period. CONCLUSION: Endoscopic submucosal dissection is applicable to superficial esophageal squamous cell neoplasms with promising results. | Kouichi Nonaka Shin Arai Keiko Ishikawa Masamitsu Nakao Yousuke Nakai Osamu Togawa Koji Nagata Michio Shimizu Yutaka Sasaki Hiroto Kita | 2010 | World Journal of Gastrointestinal Endoscopy2010，2，2： | 19 |
| 17 | Autoantibodies in primary biliary cirrhosis:Recent progress in research on the pathogenetic and clinical significance显示文摘Primary biliary cirrhosis(PBC)is a chronic progressive cholestatic liver disease characterized by immunemediated destruction of the small-and medium-sized intrahepatic bile ducts and the presence of antimitochondrial antibodies(AMA)in the serum.AMA are detected in over 90%of patients with PBC,whereas their prevalence in the general population is extremely low,varying from 0.16%to 1%.Previous studies have shown that the unique characteristics of biliary epithelial cells undergoing apoptosis may result in a highly direct and very specific immune response to mitochondrial autoantigens.Moreover,recent studies have demonstrated that serum from AMA-positive PBC patients is reactive with a number of xenobiotic modified E2 subunits of the pyruvate dehydrogenase complex,which is not observed in the serum of normal individuals.These findings indicate that chemicals originating from the environment may be associated with a breakdown in the tolerance to mitochondrial autoantigens.While it is currently generally accepted that AMA are the most specific serological markers of PBC,more than 60 au-toantibodies have been investigated in patients with PBC,and some have previously been considered specific to other autoimmune diseases.This review covers the recent progress in research on the pathogenetic and clinical significance of important autoantibodies in PBC.Determining the pathogenic role of those autoantibodies in PBC remains a priority of basic and clinical research. | Satoshi Yamagiwa Hiroteru Kamimura Masaaki Takamura Yutaka Aoyagi | 2014 | World Journal of Gastroenterology2014，20，10： | 19 |
| 18 | Relationship between post-ERCP pancreatitis and the change of serum amylase level after the procedure显示文摘AIM: To clarify the relationship between the change of serum amylase level and post-ERCP pancreatitis. METHODS: Between January 1999 and December 2002, 1291 ERCP-related procedures were performed. Serum amylase concentrations were measured before the procedure and 3, 6, and 24 h afterward. The frequency and severity of post-ERCP pancreatitis and the relationship between these phenomena and the change in amylase level were estimated. RESULTS: Post-ERCP pancreatitis occurred in 47 patients (3.6%). Pancreatitis occurred in 1% of patients with normal amylase levels 3 h after ERCP, and in 1%, 5%, 20%, 31% and 39% of patients with amylase levels elevated 1-2 times, 2-3 times, 3-5 times, 5-10 times and over 10 times the upper normal limit at 3 h after ERCP, respectively (level < 2 times vs ≥ 2 times, P < 0.001). Of the 143 patients with levels higher than the normal limit at 3 h after ERCP followed by elevation at 6 h, pancreatitis occurred in 26%. In contrast, pancreatitis occurred in 9% of 45 patients with a level higher than two times the normal limit at 3 h after ERCP followed by a decrease at 6 h (26% vs 9%, P < 0.05). CONCLUSION: Post-ERCP pancreatitis is frequently associated with an increase in serum amylase level greater than twice the normal limit at 3 h after ERCP with an elevation at 6 h. A decrease in amylase level at 6 h after ERCP suggests the unlikelihood of development of post-ERCP pancreatitis. | Kei Ito Naotaka Fujita Yutaka Noda Go Kobayashi Jun Horaguchi Osamu Takasawa Takashi Obana | 2007 | World Journal of Gastroenterology2007，13，28： | 19 |
| 19 | 比较内耳内淋巴显像和耳蜗电图及甘油试验在梅尼埃病诊断中的价值显示文摘目的:研究甘油试验、耳蜗电图、3T MRI在梅尼埃病(MD)患者中的关系。方法:评估20例患者,把稀释的钆造影剂通过鼓室注射入患者双侧的鼓室腔,24h后,通过3T MRI评估膜迷路积水的程度,此外为检测耳蜗积水,进行耳蜗电图和甘油试验。结果:经耳蜗电图检测,11例(55%)患者有阳性结果。经甘油试验检测,12例(60%)患者有阳性结果。同时采用甘油试验和耳蜗电图检测同一组患者时,75%的患者有阳性结果。用钆造影剂的3T MRI检查,19例(95%)患者有阳性结果。结论:与耳蜗电图及甘油试验检测相比,鼓室内注射钆造影剂的3T MRI,对内耳膜迷路积水的诊断更有价值。 | HISAKUNI FUKUOKA YUTAKA TAKUMI KEITA TSUKADA MAIKO MIYAGAWA TOMOHIRO OGUCHI HITOSHI UEDA MASUMI KADOYA SHIN-ICHI USAMI 张甦琳 孔维佳 | 2012 | 临床耳鼻咽喉头颈外科杂志2012，26，19： | 16 |
| 20 | Advances in understanding and treating liver diseases during pregnancy:A review显示文摘Liver disease in pregnancy is rare but pregnancyrelated liver diseases may cause threat to fetal and maternal survival.It includes pre-eclampsia;eclampsia;haemolysis,elevated liver enzymes,and low platelets syndrome;acute fatty liver of pregnancy;hyperemesis gravidarum;and intrahepatic cholestasis of pregnancy.Recent basic researches have shown the various etiologies involved in this disease entity.With these advances,rapid diagnosis is essential for severe cases since the decision of immediate delivery is important for maternal and fetal survival.The other therapeutic options have also been shown in recent reports based on the clinical trials and cooperation and information sharing between hepatologist and gynecologist is important for timely therapeutic intervention.Therefore,correct understandings of diseases and differential diagnosis from the pre-existing and co-incidental liver diseases during the pregnancy will help to achieve better prognosis.Therefore,here we review and summarized recent advances in understanding the etiologies,clinical courses and management of liver disease in pregnancy.This information will contribute to physicians for diagnosis of disease and optimum management of patients. | Kenya Kamimura Hiroyuki Abe Hirokazu Kawai Hiroteru Kamimura Yuji Kobayashi Minoru Nomoto Yutaka Aoyagi Shuji Terai | 2015 | World Journal of Gastroenterology2015，21，17： | 15 |
