1Endoscopic diagnosis of pancreaticobiliary maljunction显示文摘Pancreaticobiliary maljunction (PBM) is a congenital anomaly defined as a junction of the pancreatic and bile ducts located outside the duodenal wall, usually forming a markedly long common channel. As the action of the sphincter of Oddi does not functionally affect the junction in PBM patients, continuous pancreatobiliary reflux occurs, resulting in a high incidence of biliary cancer. PBM can be divided into PBM with biliary dilatation (congenital choledochal cyst) and PBM without biliary dilatation (maximal diameter of the bile duct ≤ 10 mm). The treatment of choice for PBM is prophylactic surgery before malignant changes can take place. Endoscopic retrograde cholangiopancreatography (ERC P) is the most effective examination method for close obs ervation of the pattern of the junction site. When the communication between the pancreatic and bile ducts is maintained, despite contraction of the sphi ncter on ERCP, PBM is diagnosed. In these pat ients, levels of pancreatic enzymes in the bile are gene rally elevated, due to continuous pancreatobiliary reflux via a long common channel. Magnetic resonance cholangiopancreatography and 3D-computed tomography can diagnose PBM, based on findings of an anomalous union between the common bile duct and the pancreatic duct, in addition to a long common channel. Endoscopic ultrasonography and intraductal ultra sonography can demonstrate the junction outside the duodenal wall, and are useful for the diagnosis of asso ciated biliary cancer. Gallbladder wall thickness on ultra so nography can be a screening test for PBM.Terumi Kamisawa Kensuke Takuma Fumihide Itokawa Takao Itoi 2011World Journal of Gastrointestinal Endoscopy2011,3,1:25
2Correlation of N-myc downstream-regulated gene 1 expression with clinical outcomes of colorectal cancer patients of different race/ethnicity显示文摘AIM: To evaluate the role of N-myc downstream-regulated gene 1 (NDRG1) expression in prognosis and survival of colorectal cancer patients with different ethnic backgrounds. METHODS: Because NDRG1 is a downstream target of p53 and hypoxia inducible factor-1α (HIF-1α),we examined NDRG1 expression together with p53 and HIF-1α by immunohistochemistry. A total of 157 colorectal cancer specimens including 80 from Japanese patients and 77 from US patients were examined. The correlation between protein expression with clinicopathological features and survival after surgery was analyzed.in colorectal tumor compared with normal epithelium in both Japanese and US patient groups. Expression of NDRG1 protein was significantly correlated with lymphatic invasion,venous invasion,depth of invasion,histopathological type,and Dukes' stage in Japanese colorectal cancer patients. NDRG1 expression was correlated to histopathological type,Dukes' stage and HIF-1α expression in US-Caucasian patients but not in US-African American patients. Interestingly,Kaplan-Meier survival analysis demonstrated that NDRG1 expression correlated significantly with poorer survival in US-African American patients but not in other patient groups. However,in p53-positive US cases,NDRG1 positivity correlated significantly with better survival. In addition,NDRG1 expression also correlated significantly with improved survival in US patients with stages Ⅲ and Ⅳ tumors without chemotherapy. In Japanese patients with stages Ⅱ and Ⅲ tumors,strong NDRG1 staining in p53-positive tumors correlated significantly with improved survival but negatively in patients without chemotherapy. CONCLUSION: NDRG1 expression was correlated with various clinicopathological features and clinical outcomes in colorectal cancer depending on the race/ethnicity of the patients. NDRG1 may serve as a biological basis for the disparity of clinical outcomes of colorectal cancer patients with different ethnic backgrounds.Minori Koshiji Kensuke Kumamoto Keiichirou Morimura Yasufumi Utsumi Michiko Aizawa Masami Hoshino Shinji Ohki Seiichi Takenoshita Max Costa Thérèse Commes David Piquemal Curtis C Harris Kam-Meng Tchou-Wong 2007World Journal of Gastroenterology2007,13,20:25
3Is endoscopic papillary balloon dilatation really a risk factor for post-ERCP pancreatitis?显示文摘Endoscopic papillary balloon dilatation(EPBD) is useful for decreasing early complications of endoscopic retrograde cholangio-pancreatography(ERCP), including bleeding, biliary infection, and perforation, but it is generally avoided in Western countries because of a relatively high reported incidence of post-ERCP pancreatitis(PEP). However, as the efficacy of endoscopic papillary largeballoon dilatation(EPLBD) becomes widely recognized, EPBD is attracting attention. Here we investigate whether EPBD is truly a risk factor for PEP, and seek safer and more effective EPBD procedures by reviewing past studies. We reviewed thirteen randomised control trials comparing EPBD and endoscopic sphincterotomy(EST) and ten studies comparing direct EPLBD and EST. Three randomized controlled trials of EPBD showed significantly higher incidence of PEP than EST, but no study of EPLBD did. Careful analysis of these studies suggested that longer and higher-pressure inflation of balloons might decrease PEP incidence. The paradoxical result that EPBD with small-calibre balloons increases PEP incidence while EPLBD does not may be due to insufficient papillary dilatation in the former. Insufficient dilatation could cause the high incidence of PEP through the use of mechanical lithotripsy and stress on the papilla at the time of stone removal. Sufficient dilation of the papilla may be useful in preventing PEP.Toshio Fujisawa Koichi Kagawa Kantaro Hisatomi Kensuke Kubota Atsushi Nakajima Nobuyuki Matsuhashi 2016World Journal of Gastroenterology2016,22,26:23
4Strategy to differentiate autoimmune pancreatitis from pancreas cancer显示文摘Autoimmune pancreatitis (AIP) is a newly described entity of pancreatitis in which the pathogenesis appears to involve autoimmune mechanisms. Based on histological and immunohistochemical examinations of various organs of AIP patients, AIP appears to be a pancreatic lesion reflecting a systemic 'IgG4-related sclerosing disease'. Clinically, AIP patients and patients with pancreatic cancer share many features, such as preponderance of elderly males, frequent initial symptom of painless jaundice, development of new-onset diabetes mellitus, and elevated levels of serum tumor markers. It is of uppermost importance not to misdiagnose AIP as pancreatic cancer. Since there is currently no diagnostic serological marker for AIP, and approach to the pancreas for histological examination is generally difficult, AIP is diagnosed using a combination of clinical, serological, morphological, and histopathological features. Findings suggesting AIP rather than pancreatic cancer include:fluctuating obstructive jaundice; elevated serum IgG4 levels; diffuse enlargement of the pancreas; delayed en- hancement of the enlarged pancreas and presence of a capsule-like rim on dynamic computed tomography; low apparent diffusion coefficient values on diffusion-weighted magnetic resonance image; irregular narrowing of the main pancreatic duct on endoscopic retrograde cholangiopancreatography; less upstream dilatation of the main pancreatic duct on magnetic resonance cholangiopancreatography, presence of other organ involvement such as bilateral salivary gland swelling, retroperitoneal fibrosis and hilar or intrahepatic sclerosing cholangitis; negative work-up for malignancy including endoscopic ultrasound-guided fine needle aspiration; and steroid responsiveness. Since AIP responds dramatically to steroid therapy, accurate diagnosis of AIP can avoid unnecessary laparotomy or pancreatic resection.Kensuke Takuma Terumi Kamisawa Rajesh Gopalakrishna Seiichi Hara Taku Tabata Yoshihiko Inaba Naoto Egawa Yoshinori Igarashi 2012World Journal of Gastroenterology2012,18,10:20
5Importance of early diagnosis of pancreaticobiliary maljunction without biliary dilatation显示文摘AIM:To clarify the strategy for early diagnosis of pancreaticobiliary maljunction(PBM) without biliary dilatation and to pathologically examine gallbladder before cancer develops.METHODS:The anatomy of the union of the pancreatic and bile ducts was assessed by using endoscopic retrograde cholangiopancreatography(ERCP).Patients with a long common channel in which communication between the pancreatic and bile ducts was maintained even during sphincter contraction were diagnosed as having PBM.Of these,patients in which the maximal diameter of the bile duct was less than 10 mm were diagnosed with PBM without biliary dilatation.The process of diagnosing 54 patients with PBM without biliary dilatation was retrospectively investigated.Histopathological analysis of resected gallbladder specimens from 8 patients with PBM without biliary dilatation or cancer was conducted.RESULTS:Thirty-six PBM patients without biliary dilatation were diagnosed with gallbladder cancer after showing clinical symptoms such as abdominal or back pain(n = 16) or jaundice(n = 12).Radical surgery for gallbladder cancer was only possible in 11 patients(31%) and only 4 patients(11%) survived for 5 years.Eight patients were suspected as having PBM without biliary dilatation from the finding of gallbladder wall thickening on ultrasound and the diagnosis was confirmed by ERCP and/or magnetic resonance cholangiopancreatography(MRCP).The median age of these 8 patients was younger by a decade than PBM patients with gallbladder cancer.All 8 patients underwent prophylactic cholecystectomy and bile duct cancer has not occurred.Wall thickness and mucosal height of the 8 resected gallbladders were significantly greater than controls,and hyperplastic changes,hypertrophic muscular layer,subserosal fibrosis,and adenomyomatosis were detected in 7(88%),5(63%),7(88%) and 5(63%) patients,respectively.Ki-67 labeling index was high and K-ras mutation was detected in 3 of 6 patients.CONCLUSION:To detect PBM without biliary dilatation before onset of gallbladder cancer,we should perform MRCP for individuals showing increased gallbladder wall thickness on ultrasound.Kensuke Takuma Terumi Kamisawa Taku Tabata Seiichi Hara Sawako Kuruma Yoshihiko Inaba Masanao Kurata Goro Honda Koji Tsuruta Shin-ichiro Horiguchi Yoshinori Igarashi 2012World Journal of Gastroenterology2012,18,26:13
6Sclerosing cholangitis associated with autoimmune pancreatitis differs from primary sclerosing cholangitis显示文摘AIM:To clarify the characteristic features of biliary le-sions in patients with autoimmune pancreatitis(AIP) and compare them with those of primary sclerosing cholangitis(PSC) .METHODS:The clinicopathological characteristics of 34 patients with sclerosing cholangitis(SC) associated with AIP were compared with those of 4 patients with PSC.RESULTS:SC with AIP occurred predominantly in el-derly men.Obstructive jaundice was the most frequent initial symptom in SC with AIP.Only SC patients with AIP had elevated serum IgG4 levels,and sclerosing diseases were more frequent in these patients.SC pa-tients with AIP responded well to steroid therapy.Seg-mental stenosis of the lower bile duct was observed only in SC patients with AIP,but a beaded and pruned-tree appearance was detected only in PSC patients.Dense infi ltration of IgG4-positive plasma cells was de-tected in the bile duct wall and the periportal area,as well as in the pancreas,of SC patients with AIP.CONCLUSION:SC with AIP is distinctly different from PSC.The two diseases can be discriminated based on cholangiopancreatographic findings and serum IgG4 levels.Terumi Kamisawa Kensuke Takuma Hajime Anjiki Naoto Egawa Masanao Kurata Goro Honda Kouji Tsuruta 2009World Journal of Gastroenterology2009,15,19:9
7Is hepatic arterial infusion chemotherapy effective treatment for advanced hepatocellular carcinoma resistant to transarterial chemoembolization?显示文摘AIM:To evaluate the effectiveness of hepatic arterial infusion chemotherapy(HAIC) for advanced hepatocellular carcinoma(HCC) resistant to transarterial chemoembolization(TACE).METHODS:This study was conducted on 42 patients who received HAIC for advanced HCC between 2001and 2010 at our hospital.5-fluorouracil(5-FU) was administered continuously for 24 h from day 1 to day 5 every 2-4 wk via an injection reservoir.Intra-arterial cisplatin or subcutaneous interferon was administered in combination with the 5-FU.The patients enrolled in this retrospective study were divided into two groups according to whether or not they fulfilled the criteria for resistance to TACE proposed by the Japan Society of Hepatology in 2010(written in Japanese);one group of patients who did not fulfill the criteria for TACE resistance(group A,n = 23),and another group who fulfilled the criteria for TACE resistance(group B,n = 19).We compared the outcomes in terms of the response and survival rates between the two groups.RESULTS:Both the response rate and tumor suppression rate following HAIC were significantly superior in group A than in group B(response rate:48% vs 16%,P = 0.028,tumor suppression rate:87% vs 53%,P = 0.014).Furthermore,both the progression-free survival rate and survival time were significantly superior in group A than in group B(3-,6-,12-,and 24-mo = 83%,70%,29% and 20% vs 63%,42%,16% and 0%,respectively,P = 0.040,and 9.8 mo vs 6.2 mo,P = 0.040).A multivariate analysis(Cox proportional hazards regression model) showed that resistance to TACE was an independent predictor of poor survival(P = 0.007).CONCLUSION:HAIC administrating 5-FU was not effective against advanced HCC resistant to TACE.Other tools for treatment,i.e.,molecular-targeting agents may be considered for these cases.Hiroyuki Kirikoshi Masato Yoneda Hironori Mawatari Koji Fujita Kento Imajo Shingo Kato Kaori Suzuki Noritoshi Kobayashi Kensuke Kubota Shin Maeda Atsushi Nakajima Satoru Saito 2012World Journal of Gastroenterology2012,18,16:9

9Early effects of oral administration of omeprazole and roxatidine on intragastric pH显示文摘Objective:The ideal medication for the treatment of acid-related diseases,e.g.,peptic ulcers,stress-related gastric bleeding,functional dyspepsia,and gastroesophageal reflux disease,should have a rapid onset of action to promote hemostasis and relieve the symptoms.The aim of our study was to investigate the inhibitory effects on gastric acid secretion of a single oral administration of a proton pump inhibitor,omeprazole 20 mg,and an H2-receptor antagonist,roxatidine 75 mg.Methods:Ten Helicobacter pylori-negative male subjects participated in this randomized,two-way crossover study.Intragastric pH was monitored continuously for 6 h after single oral administration of omeprazole 20 mg and roxatidine 75 mg.Each administration was separated by a 7-d washout period.Results:During the 6-h study period,the average pH after administration of roxatidine was higher than that after administration of omeprazole(median:4.45 vs.2.65;P=0.0367).Also during the 6-h study period,a longer duration of maintenance at pH above 2,5,and 6 was observed after administration of roxatidine 75 mg than after administration of omeprazole 20 mg(median:90.6% vs.55.2%,P=0.0284;43.7% vs.10.6%,P=0.0125;40.3% vs.3.3%,P=0.0125;respectively).Conclusions:In Helicobacter pylori-negative healthy male subjects,oral administration of roxatidine 75 mg increased the intragastric pH more rapidly than that of omeprazole 20 mg.Hiroshi IIDA Shingo KATO Yusuke SEKINO Eiji SAKAI Takashi UCHIYAMA Hiroki ENDO Kunihiro HOSONO Yasunari SAKAMOTO Koji FUJITA Masato YONEDA Tomoko KOIDE Hirokazu TAKAHASHI Chikako TOKORO Ayumu GOTO Yasunobu ABE Noritoshi KOBAYASHI Kensuke KUBOTA Eiji GOTOH Shin MAEDA Atsushi NAKAJIMA Masahiko INAMORI 2012Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2012,13,1:6
10通过水溶液还原法用抗坏血酸制备纳米铜颗粒(英文)显示文摘通过水溶液还原法用抗坏血酸还原Cu2+制备纳米铜颗粒,并研究溶液pH和Cu2O平均粒径对纳米铜颗粒制备的影响。在溶液pH值为3、5和7时,可制得铜颗粒,并且在pH=7时制得的铜颗粒粒径最小。在溶液pH为9和11时无法制得铜颗粒。Cu2O的平均粒径能影响铜粉的粒径。Cu2O的平均粒径越大,得到的铜颗粒越大。通过对反应过程中不同时间点收集的样品进行XRD分析,可探索出反应的进程。在反应过程中,Cu(OH)2首先作为前驱体出现,然后被还原为Cu2O,最后被还原为铜颗粒。刘清明 Takehiro YASUNAMI Kensuke KURUDA Masazumi OKIDO 2012Transactions of Nonferrous Metals Society of China2012,22,9:6
11miR-122-5p as a novel biomarker for alpha-fetoproteinproducing gastric cancer显示文摘AIM To investigate the clinical utility of alpha-fetoprotein(AFP)-producing gastric cancer(AFPGC)-specific microRNA(mi RNA)for monitoring and prognostic prediction of patients.METHODS We performed a comprehensive miRNA array-based approach to compare miRNA expression levels between AFP-positive and AFP-negative cells in three patients with primary AFPGC.We next examined the expression levels of the selected miRNAs in five AFPGC and ten non-AFPGC tissue samples by quantitative reverse transcription-polymerase chain reaction to validate their utility.We also investigated the expression levels of the selected miRNA not only in tissue but also in plasma samples.Moreover,we investigated the relationship between plasma AFP levels and plasma selected miRNA expression levels,and also investigated the correlation of the selected miRNA expression levels and malignant potential.RESULTS Among the five miRNAs selected from the miRNA array results,the expression levels of miR-122-5p were significantly higher in the AFPGC patients than in the non-AFPGC patients(P<0.05).In tissue samples,mi R-122-5p expression level tended to be lower in the non-AFPGC tissue than the normal gastric mucosa.Conversely,in the AFPGC tissue,miR-122-5p expression level was significantly higher in the AFPGC tissue than both the normal gastric mucosa and the nonAFPGC tissue samples(P<0.05).Plasma mi R-122-5p expression levels were also significantly higher in the AFPGC patients than the health volunteers and the nonAFPGC patients(P<0.05)and were strongly correlated with plasma AFP levels(r=0.7975,P<0.0001).Moreover,the correlation of miR-122-5p expression in tissue samples with malignant potential was stronger than that of plasma AFP level in the AFPGC patients.In contrast,no correlation was found between mi R-122-5p expression levels and liver metastasis in the non-AFPGC patients.CONCLUSION miR-122-5p might be a useful biomarker for early detection and disease monitoring in AFPGC.Suguru Maruyama Shinji Furuya Kensuke Shiraishi Hiroki Shimizu Hidenori Akaike Naohiro Hosomura Yoshihiko Kawaguchi Hidetake Amemiya Hiromichi Kawaida Makoto Sudo Shingo Inoue Hiroshi Kono Daisuke Ichikawa 2018World Journal of Gastrointestinal Oncology2018,10,10:6
12Utility of pancreatography for diagnosing autoimmune pancreatitis显示文摘AIM: To identify pancreatographic findings that facilitate differentiating between autoimmune pancreatitis (AIP) and pancreatic cancer (PC) on endoscopic retrograde cholangiopancreatography (ERCP) and magnetic resonance cholangiopancreatography (MRCP). METHODS: ERCP findings of 48 AIP and 143 PC patients were compared. Diagnostic accuracies for AIP by ERCP and MRCP were compared in 30 AIP patients. RESULTS: The following ERCP findings suggested a diagnosis of AIP rather than PC. Obstruction of the main pancreatic duct (MPD) was more frequently detected in PC (P < 0.001). Skipped MPD lesions were detected only in AIP (P < 0.001). Side branch derivation from the narrowed MPD was more frequent in AIP (P < 0.001). The narrowed MPD was longer in AIP (P < 0.001), and a narrowed MPD longer than 3 cm was more frequent in AIP (P < 0.001). Maximal diameter of the upstream MPD was smaller in AIP (P < 0.001), and upstream dilatation of the MPD less than 5 mm was more frequent in AIP (P < 0.001). Stenosis of the lower bile duct was smooth in 87% of AIP and irregular in 65% of PC patients (P < 0.001). Stenosis of the intrahepatic or hilar bile duct was detected only in AIP (P = 0.001). On MRCP, diffuse narrowing of the MPD on ERCP was shown as a skipped non-visualized lesion in 50% and faint visualization in 19%, but segmental narrowing of the MPD was visualized faintly in only 14%. CONCLUSION: Several ERCP findings are useful for differentiating AIP from PC. Although MRCP cannot replace ERCP for the diagnostic evaluation of AIP, some MRCP findings support the diagnosis of AIP.Kensuke Takuma Terumi Kamisawa Taku Tabata Yoshihiko Inaba Naoto Egawa Yoshinori Igarashi 2011World Journal of Gastroenterology2011,17,18:6
13Differences between diffuse and focal autoimmune pancreatitis显示文摘AIM:To investigate differences in clinical features between diffuse-and focal-type autoimmune pancreatitis(AIP).METHODS:Based on radiological findings by computed tomography and/or magnetic resonance imaging,we divided 67 AIP patients into diffuse type(D type) and focal type(F type).We further divided F type into head type(H type) and body and/or tail type(B/T type) according to the location of enlargement.Finally,we classified the 67 AIP patients into three groups:D type,H type and B/T type.We compared the three types of AIP in terms of clinical,laboratory,radiological,functional and histological findings and clinical course.RESULTS:There were 34 patients with D-type,19 with H-type and 14 with B/T-type AIP.Although obstructive jaundice was frequently detected in D-typepatients(88%) and H-type patients(68%),no B/T-type patients showed jaundice as an initial symptom(P < 0.001).There were no differences in frequency of abdominal pain,but acute pancreatitis was associated more frequently in B/T-type patients(36%) than in D-type patients(3%)(P = 0.017).Serum immunoglobulin G(IgG)4 levels were significantly higher in D-type patients(median 309 mg/dL) than in B/T-type patients(133.5 mg/dL)(P = 0.042).Serum amylase levels in B/T-type patients(median:114 IU/L) were significantly greater than in H-type patients(72 IU/L)(P = 0.049).Lymphoplasmacytic sclerosing pancreatitis(LPSP) was histologically confirmed in 6 D-type,7 H-type and 4 B/T-type patients;idiopathic duct-centric pancreatitis was observed in no patients.Marked fibrosis and abundant infiltration of CD20-positive B lymphocytes with few IgG4-positive plasma cells were detected in 2 B/T-type patients.Steroid therapy was effective in all 50 patients(31 D type,13 H type and 6 B/T type).Although AIP relapsed during tapering or after stopping steroids in 3 D-type and 3 H-type patients,no patients relapsed in B/T type.During follow-up,radiological features of 6 B/T-type patients were not changed and 1 B/T-type patient improved naturally.CONCLUSION:Clinical features of H-type AIP were similar to those of D-type,but B/T-type differed from D and H types.B/T-type may involve diseases other than LPSP.Taku Tabata Terumi Kamisawa Kensuke Takuma Seiichi Hara Sawako Kuruma Yoshihiko Inaba 2012World Journal of Gastroenterology2012,18,17:6
14苏州市生活垃圾两种处置方法的生命周期影响评价显示文摘采用生命周期评价的方法,比较了苏州市垃圾填埋和垃圾焚烧2种处置方法对环境的影响。研究的系统范围主要包括垃圾收集、垃圾运输、垃圾填埋或焚烧以及发电等几个部分。采用收集的垃圾组分数据,利用IPCC推荐的模型等,计算了垃圾填埋和垃圾焚烧时CO2等气体污染物的排放量。根据对垃圾渗滤液的实测数据,计算了水污染物的排放量。环境影响评价采用日本开发的AIST-LCA Ver4计算机软件进行。计算结果表明:垃圾填埋的生态币值要大得多,可见垃圾焚烧对环境的影响比垃圾填埋的影响要小。所获得的结论较为客观地反映了对环境的影响,可以作为中国城市垃圾处置决策的参考依据。韦保仁 王俊 Tahara Kiyotaka Kobayashi Kensuke Sagisaka Masayuki 2009环境工程学报2009,3,8:5
15Ultrasound-guided vs endoscopic ultrasound-guided fine-needle aspiration for pancreatic cancer diagnosis显示文摘AIM: To clarify the effectiveness and safety of endo- scopic ultrasound-guided fine-needle aspiration (EUS-FNA) for the diagnosis of pancreatic cancer (PC). METHODS: Patients who were diagnosed with unresectable, locally advanced or metastatic PC between February 2006 and September 2011 were selected for this retrospective study. FNA biopsy for pancreatic tumors had been performed percutaneously under extracorporeal ultrasound guidance until October 2009; then, beginning in November 2009, EUS-FNA has been performed. We reviewed the complete medical records of all patients who met the selection criteria for the following data: sex, age, location and size of the targeted tumor, histological and/or cytological findings, details of puncture procedures, time from day of puncture until day of definitive diagnosis, and details of severe adverse events. RESULTS: Of the 121 patients who met the selection criteria, 46 had a percutaneous biopsy (Group A) and 75 had an EUS-FNA biopsy (Group B). Adequate cytological specimens were obtained in 42 Group A patients (91.3%) and all 75 Group B patients (P=0.0192), and histological specimens were obtained in 41 Group A patients (89.1%) and 65 Group B patients (86.7%). Diagnosis of malignancy by cytology was positive in 33 Group A patients (78.6%) and 72 Group B patients (94.6%) (P=0.0079). Malignancy by both cytology and pathology was found in 43 Group A (93.5%) and 73 Group B (97.3%) patients. The mean period from the puncture until the cytological diagnosis in Group B was 1.7 d, which was significantly shorter than that in Group A (4.1 d) (P < 0.0001). Severe adverse events were experienced in two Group A patients (4.3%) and in one Group B patient (1.3%). CONCLUSION: EUS-FNA, as well as percutaneous needle aspiration, is an effective modality to obtain cytopathological confirmation in patients with advanced PC.Masato Matsuyama Hiroshi Ishii Kensuke Kuraoka Seigo Yukisawa Akiyoshi Kasuga Masato Ozaka Sho Suzuki Kouichi Takano Yuko Sugiyama Takao Itoi 2013World Journal of Gastroenterology2013,19,15:5
16Electroacupuncture improves neuronal function by stimulation of ascending peripheral nerve conduction in rats with spinal cord injury显示文摘OBJECTIVE: To establish a method of transient sciatic nerve blockade and to examine the involvement of the ascending peripheral nerve pathway in the therapeutic effect of electroacupuncture at Zusanli(ST 36) in rats with spinal cord injury(SCI).METHODS: We examined the transient effect of daily lidocaine administration into the posteromedial part of the greater trochanter on sciatic nerve function using electrophysiological examination and histopathology of the sciatic nerve. Rats were divided into three groups: an SCI group(SCI without treatment), an SCI with electroacupuncture treatment(SCI-EA) group, and an SCI with nerve block and electroacupuncture(SCI-NB-EA) group(nerve block was achieved by lidocaine administration to transiently block the ascending peripheral nerve pathway). Behavioral tests and electrophysiological examinations were performed to evaluate recovery of neurological function.RESULTS: Sciatic nerve conduction was normal immediately before daily lidocaine administration.Histopathological analysis also indicated normal sciatic nerve, confirming that lidocaine nerve blockade was suitable and reversible for transiently eliminating nerve transmission. Neurological function in the SCI-EA group was superior to that in the SCI group, while no differences were found between the SCI and SCI-NB-EA groups.CONCLUSION: Electroacupuncture treatment can promote recovery of neurological function. Facilitation of nerve conduction may play an important role in this recovery.Song Meng Chen Wu Kamiie Junichi Okuno Seiichi Orito Kensuke 2019Journal of Traditional Chinese Medicine2019,39,4:5

18Levovist ultrasonography imaging in intracystic hemorrhage of simple liver cyst显示文摘The differential diagnosis between intracystic hemorrhage and cystadenocarcinoma of the liver is often difficult even with the use of various imaging modalities. A 73-year-old woman was admitted to our hospital with the complaint of right upper quadrant pain. Ultrasonography (US) demonstrated a heterogeneous echogenic cyst measuring 11 cm × 8 cm in size in S2 of the liver, indicated intracystic hemorrhage of simple liver cyst or cystadenocarcinoma, but the differential diagnosis was considerably difficult. Levovist (Schering, Berlin, Germany) US revealed no enhancement of the intracystic structures, suggesting a clot in the case of intracystic hemorrhage. An operation was performed and the resected lesion showed a solitary benign liver cyst, measuring 5.5 cm × 4.7 cm × 8.5 cm containing a large blood clot. The patient had an uneventful recovery after the surgery.

19Shape of Barrett's epithelium is associated with prevalence of erosive esophagitis显示文摘AIM:To test the hypothesis that the shape and length of Barrett's epithelium are associated with prevalence of erosive esophagitis.METHODS:A total study population comprised 869 patients who underwent endoscopy during a health checkup at our hospital.The presence and extent of Barrett's epithelium were diagnosed based on the Prague C & M Criteria.We originally classified cases of Barrett's epithelium into two types based on its shape,namely,flamelike and lotus-like Barrett's epithelium,and into two groups based on its length,its C extent < 2 cm,and ≥ 2 cm.Correlation of shape and length of Barrett's epithelium with erosive esophagitis was examined.RESULTS:Barrett's epithelium was diagnosed in 374 cases(43%).Most of these were diagnosed as shortsegment Barrett's epithelium.The prevalence of erosive esophagitis was significantly higher in subjects with flame-like than lotus-like Barrett's epithelium,and in those with a C extent of ≥ 2 cm than < 2 cm.CONCLUSION:Flame-like rather than lotus-like Barrett's epithelium,and Barrett's epithelium with a longer segment were more strongly associated with erosive esophagitis.Tomoyuki Akiyama Masahiko Inamori Hiroshi Iida Hiroki Endo Kunihiro Hosono Yasunari Sakamoto Koji Fujita Masato Yoneda Hirokazu Takahashi Tomoko Koide Chikako Tokoro Ayumu Goto Yasunobu Abe Takeshi Shimamura Noritoshi Kobayashi Kensuke Kubota Satoru Saito Atsushi Nakajima 2010World Journal of Gastroenterology2010,16,4:4
20Breakthrough therapy for peritoneal carcinomatosis of gastric cancer:Intraperitoneal chemotherapy with taxanes显示文摘The effect of chemotherapy on peritoneal carcinomatosis(PC) of gastric cancer remains unclear.Recently,the intraperitoneal(IP) administration of taxanes [e.g.,paclitaxel(PTX) and docetaxel(DOC)] during the perioperative period has shown promising results.Herein,we summarized the rationale and methodology for using IP chemotherapy with taxanes and reviewed the clinical results.IP administered taxanes remain in the IP space at an extremely high concentration for 48-72 h.The drug directly infiltrates peritoneal metastatic nodules from the surface and then produces antitumor effects,making it ideal for IP chemotherapy.There are two types of perioperative IP chemotherapy with taxanes: neoadjuvant intraperitoneal and systemic chemotherapy and sequential perioperative intraperitoneal chemotherapy(SPIC).In SPIC,patients receive neoadjuvant IP chemotherapy and the same regimen of IP chemotherapy after cytoreductive surgery(CRS) until disease progression.Usually,a taxane dissolved in 500-1000 m L of saline at ordinary temperature is administered through an IP access port on an outpatient basis.According to phase Ⅰ?studies,the recommended doses(RD) are as follows: IP DOC,45-60 mg/m2; IP PTX [without intravenous(IV) PTX],80 mg/m2; and IP PTX(with IV PTX),20 mg/m2.Phase Ⅱ studies have reported a median survival time of 14.4-24.6 mo with a 1-year overall survival of 67%-78%.A phase Ⅲ study comparing S-1 in combination with IP and IV PTX to S-1 with IV cisplatin started in 2011.The prognosis of patients who underwent CRS was better than that of those who did not; however,this was partly due to selection bias.Although several phase Ⅱ studies have shown promising results,a randomized controlled study is needed to validate the effectiveness of IP chemotherapy with taxanes for PC of gastric cancer.Hironori Yamaguchi Joji Kitayama Hironori Ishigami Shinsuke Kazama Hiroaki Nozawa Kazushige Kawai Keisuke Hata Tomomichi Kiyomatsu Toshiaki Tanaka Junichiro Tanaka Takeshi Nishikawa Kensuke Otani Koji Yasuda Soichiro Ishihara Eiji Sunami Toshiaki Watanabe 2015World Journal of Gastrointestinal Oncology2015,7,11:3
