| 1 | 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 |

| 3 | Single-incision laparoscopic cholecystectomy:Single institution experience and literature review显示文摘Single-incision laparoscopic surgery is a rapidly evolving field as a bridge between traditional laparoscopic surgery and natural orifice transluminal endoscopic surgery.We report one of the initial clinical experiences in Japan with this new technique.Four cases of gallbladder diseases were selected for this new technique.A single curved intra-umbilical 25-mm incision was made by pulling out the umbilicus.A 12-mm trocar was placed through an open approach,and the abdominal cavity was explored with a 10-mm semiflexible laparoscope.Two 5-mm ports were inserted laterally from the laparoscope port.A 2-mm mini-loop retractor was inserted to retract the fundus of the gallbladder.Dissection was performed using an electric cautery hook and an Endograsper roticulator.There were two women and two men with a mean age of 50.5 years(range:40-61 years).All procedures were completed successfully without any perioperative complications.In all cases,there was no need to extend the skin incision.Average operative time was 88.8 min.Postoperative follow-up didnot reveal any umbili-cal wound complication.Single-incision laparoscopic cholecystectomy is feasible and a promising alternative method as scarless abdominal surgery for the treatment of some patients with gallbladder disease. | Yasumitsu Hirano Toru Watanabe Tsuneyuki Uchida Shuhei Yoshida Kanae Tawaraya Hideaki Kato Osamu Hosokawa | 2010 | World Journal of Gastroenterology2010，16，2： | 23 |
| 4 | Arsenic Disulfide Induced Apoptosis and Concurrently Promoted Erythroid Differentiation in Cytokine-Dependent Myelodysplastic Syndrome-progressed Leukemia Cell Line F-36p with Complex Karyotype Including Monosomy 7显示文摘Objective:Acute myeloid leukemia progressed from myelodysplastic syndrome(MDS/AML)is generally incurable with poor prognosis for complex karyotype including monosomy 7(-7).Qinghuang Powder(青黄散,QHP),which includes Qing Dai(Indigo naturalis)and Xiong Huang(realgar)in the formula,is effective in treating MDS or MDS/AML even with the unfavorable karyotype,and its therapeutic efficacy could be enhanced by increasing the Xiong huang content in the formula,while Xiong huang contains>90%arsenic disulfide(As_2S_2).F-36p cell line was established from a MDS/AML patient with complex karyotype including-7,and was in cytokine-dependent.The present study was to investigate the effects of AS_2S_2 on F-36p cells.Methods:Cell proliferation was measured by an3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(MTT)assay.Cell apoptosis was identified by Annexin V-staining.Cell viability was determined by a propidium iodide(PI)exclusion.Erythroid differentiation was evaluated by the expression of cell surface antigen CD235a(GpA).Results:After treatment with AS_2S_2,at concentrations of 0.5to 16μmol/L for 72 h,As_2S_2 inhibited the proliferation of F-36p cells.The 50%inhibitory concentrations(IC_(50))of As_2S_2against the proliferation of F-36p cells was 6μmol/L.The apoptotic cells significantly increased in a dose-dependent mannar(P<0.05).The cell viabilities were significantly inhibited by As_2S_2 dose-dependent in a dose-dependent manner(P<0.05).Significant increases of CD235a-positive cells were concurrently observed(P<0.05)also in a dosedependent manner.Conclusions:As_2S_2 could inhibit proliferation and viability,induce apoptosis,and concurrently promote erythroid differentiation dose-dependently in F-36p cells.AS_2S_2 can inhibit proliferation and viability,induce apoptosis,and concurrently promote erythroid differentiation in cytokine-dependent MDS-progressed human leukemia cell line F-36p with complex karyotype including-7.The data suggest that QHP and/or As_2S_2 could be a potential candidate in the treatment of MDS or MDS/AML even with unfavorable cytogenetics. | 胡晓梅 Sachiko Tanaka Kenji Onda 袁博 Hiroo Toyoda 麻柔 刘峰 Toshihiko Hirano | 2014 | Chinese Journal of Integrative Medicine2014，20，5： | 20 |

| 7 | Mortalin imaging in normal and cancer cells with quantum dot immuno conjugates显示文摘Quantum dots are the nanoparticles that are recently emerging as an alternative to organic fluorescence probes in cell biology and biomedicine,and have several predictive advantages.These include their i)broad absorption spectra allowing visualization with single light source,ii)exceptional photo-stability allowing long term studies and iii)narrow and symmetrical emission spectrum that is controlled by their size and material composition.These unique properties allow simultaneous excitation of different size of quantum dots with a single excitation light source,their simultaneous resolution and visualization as different colors.At present there are only a few studies that have tested quantum dots in cellular imaging.We describe here the use of quantum dots in mortalin imaging of normal and cancer cells.Mortalin staining pattern with quantum dots in both normal and cancer cells mimicked those obtained with organic florescence probes and were considerably stable. | ZEENIA KAUL TOMOKO YAGUCHI SUNIL C KAUL TAKASHI HIRANO RENU WADHWA KAZUNARI TAIRA | 2003 | Cell Research2003，13，6： | 14 |
| 8 | Development of osteomalacia in a post-liver transplant patient receiving adefovir dipivoxil显示文摘We report the case of a patient treated with living donor-related liver transplantation who suffered from osteomalacia during adefovir dipivoxil (ADV)-containing antiviral therapy for lamivudine-resistant hepatitis B virus infection. The patient had generalized bone pain,with severe hypophosphatemia after 20 mo of ADV therapy. Radiographic studies demonstrated the presence of osteomalacia. The peak plasma ADV level was 38 ng/mL after administration of ADV at 10mg/day. It was also found that ADV affected the metabolism of tacrolimus,a calcineurin-inhibitor,and caused an increase in the plasma levels of tacrolimus. The disability was reversed with the withdrawal of ADV and with mineral supplementation. ADV can cause an elevation of plasma tacrolimus levels,which may be associated with renal dysfunction. High levels of ADV and tacrolimus can cause nephrotoxicity and osteomalacia. This case highlights the importance of considering a diagnosis of osteomalacia in liver transplantation recipients treated with both ADV and tacrolimus. | Masami Minemura Yoshiharu Tokimitsu Kazuto Tajiri Yasuhiro Nakayama Kengo Kawai Hiroshi Kudo Katsuharu Hirano Yoshinari Atarashi Yutaka Yata Satoshi Yasumura Terumi Takahara Toshiro Sugiyama | 2010 | World Journal of Hepatology2010，2，12： | 13 |

| 10 | Efficacy of multislice computed tomography for gastroenteric and hepatic surgeries显示文摘AIM: To determine the efficacy of multislice CT for gastroenteric and hepatic surgery.METHODS: Dual-phase helical computed tomography was performed in 50 of 51 patients who underwent gastroenteric and hepatic surgeries. Twenty-eight, eighteen and four patients suffering from colorectal cancer, gastric cancer,and liver cancer respectively underwent colorectal surgery (laparoscopic surgery: 6 cases), gastrectomy, and hepatectomy. Three-dimensional computed tomography imaging of the inferior mesenteric artery, celiac artery and hepatic artery was performed. And in the follow-up examination of postoperative patients, multiplanar reconstruction image was made in case of need.RESULTS: Scans in 50 patients were technically satisfactory and included in the analysis. Depiction of major visceral arteries, which were important for surgery and other treatments, could be done in all patients.Preoperative visualization of the left colic artery and sigmoidal arteries, the celiac artery and its branches, and hepatic artery was very useful to lymph node dissection,the planning of a reservoir and hepatectomy. And multiplanar reconstruction image was helpful to diagnosis for the postoperative follow-up of patients.CONCLUSION: Three-dimensional volume rendering or multiplanar reconstruction imaging performed by multislice computed tomography was very useful for gastroenteric and hepatic surgeries. | Hiroshi Ohtani Hidemi Kawajiri Yuichi Arimoto Koichi Ohno Yasuhisa Fujimoto Hiroko Oba Kenji Adachi Masaya Hirano Shoichi Terakawa Mitsuo Tsubakimoto | 2005 | World Journal of Gastroenterology2005，11，10： | 9 |
| 11 | Single-incision laparoscopic surgery for colorectal cancer显示文摘AIM: To determine the effect of single-incision laparoscopic colectomy(SILC) for colorectal cancer on short-term clinical and oncological outcomes by comparison with multiport conventional laparoscopic colectomy(CLC).METHODS: A systematic review was performed using MEDLINE for the time period of 2008 to December 2014 to retrieve all relevant literature. The search terms were 'laparoscopy', 'single incision', 'single port', 'single site', 'SILS', 'LESS' and 'colorectal cancer'. Publications were included if they were randomized controlled trials, case-matched controlled studies, or comparative studies, in which patients underwent single-incision(SILS or LESS) laparoscopic colorectal surgery. Studies were excluded if they were non-comparative, or not including surgery involving the colon or rectum. A total of 15 studies with 589 patients who underwent SILC for colorectal cancer were selected.RESULTS: No significant differences between the groups were noted in terms of mortality or morbidity. The benefit of the SILC approach included reduction in conversion rate to laparotomy, but there were no significant differences in other short-term clinical outcomes between the groups. Satisfactory oncological surgical quality was also demonstrated for SILC for the treatment of colorectal cancer with a similar average lymph node harvest and proximal and distal resection margin length as multiport CLC.CONCLUSION: SILC can be performed safely with similar short-term clinical and oncological outcomes as multiport CLC. | yasumitsu hirano masakazu hattori kenji douden yasuhiro ishiyama yasuo hashizume | 2016 | World Journal of Gastrointestinal Surgery2016，8，1： | 9 |
| 12 | Improvement of prognosis for unresectable biliary tract cancer显示文摘AIM:To evaluate the chemotherapeutic outcomes and confirm the recent improvement of prognosis for unresectable biliary tract cancer.METHODS:A total of 186 consecutive patients with unresectable biliary tract cancer,who had been treated with chemotherapy between 2000 and 2009 at five institutions in Japan,were retrospectively analyzed.These patients were divided into three groups based on the year beginning chemotherapy:Group A(2000-2003),Group B(2004-2006),and Group C(2007-2009).The data were fixed at the end of December 2011.Overall survival and time-to-progression were analyzed and compared chronologically.RESULTS:No patient characteristics were significantly different among the three groups.The gallbladder was involved in about half of the patients in each group,and metastatic biliary tract cancer was present in three quarters of the enrollees.In Group A,5-fluorouracilbased chemotherapies were primarily selected as firstline chemotherapy,and only 24% were treated with second-line chemotherapy.In Group B,gemcitabine or S-1 monotherapy was mainly introduced as firstline chemotherapy,and 51% of the patients who were refractory to first-line chemotherapy were treated with second-line chemotherapy mainly with monotherapy.In Group C,the combination therapy with gemcitabine and S-1 was mainly chosen as first-line chemotherapy,and 53% of the patients refractory to first-line chemotherapy were treated with second-line chemotherapy mainly with combination therapy.The median timeto-progressions were 4.4 mo,3.5 mo and 5.9 mo in Groups A,B and C,respectively(4.4 mo vs 3.5 mo vs 5.9 mo,P < 0.01).The median overall survivals were 7.1,7.3,and 11.7 mo in Groups A,B and C(7.1 mo vs 7.3 mo vs 11.7 mo,P = 0.03).Induction rates of all three drugs(gemcitabine,platinum analogs,and fluoropyrimidine) in Groups A,B and C were 4%,2% and 27%(4% vs 2% vs 27%,P < 0.01).CONCLUSION:The prognosis of unresectable biliary tract cancer has improved recently.Using three effective drugs(gemcitabine,platinum analogs,and fluoropyrimidine) may improve the prognosis of this cancer. | Takashi Sasaki Hiroyuki Isayama Yousuke Nakai Naminatsu Takahara Naoki Sasahira Hirofumi Kogure Suguru Mizuno Hiroshi Yagioka Yukiko Ito Natsuyo Yamamoto Kenji Hirano Nobuo Toda Minoru Tada Masao Omata Kazuhiko Koike | 2013 | World Journal of Gastroenterology2013，19，1： | 8 |

| 14 | Usefulness of urinary trypsinogen-2 and trypsinogen activation peptide in acute pancreatitis:A multicenter study in Japan显示文摘BACKGROUND Rapid urinary trypsinogen-2 dipstick test and levels of urinary trypsinogen-2 and trypsinogen activation peptide(TAP) concentration have been reported as prognostic markers for the diagnosis of acute pancreatitis.AIM To reconfirm the validity of all these markers in the diagnosis of acute pancreatitis by undertaking a multi-center study in Japan.METHODS Patients with acute abdominal pain were recruited from 17 medical institutions in Japan from April 2009 to December 2012. Urinary and serum samples were collected twice, at enrollment and on the following day for measuring target markers. The diagnosis and severity assessment of acute pancreatitis were assessed based on prognostic factors and computed tomography(CT) Grade of the Japanese Ministry of Health, Labour, and Welfare criteria.RESULTS A total of 94 patients were enrolled during the study period. The trypsinogen-2 dipstick test was positive in 57 of 78 patients with acute pancreatitis(sensitivity,73.1%) and in 6 of 16 patients with abdominal pain but without any evidence of acute pancreatitis(specificity, 62.5%). The area under the curve(AUC) score of urinary trypsinogen-2 according to prognostic factors was 0.704, which was highest in all parameter. The AUC scores of urinary trypsinogen-2 and TAP according to CT Grade were 0.701 and 0.692, respectively, which shows higher than other pancreatic enzymes. The levels of urinary trypsinogen-2 and TAP were significantly higher in patients with extended extra-pancreatic inflammation as evaluated by CT Grade.CONCLUSION We reconfirmed urinary trypsinogen-2 dipstick test is useful as a marker for the diagnosis of acute pancreatitis. Urinary trypsinogen-2 and TAP may be considered as useful markers to determine extra-pancreatic inflammation in acute pancreatitis. | Hiroaki Yasuda Keisho Kataoka Yoshifumi Takeyama Kazunori Takeda Tetsuhide Ito Toshihiko Mayumi Shuji Isaji Tetsuya Mine Motoji Kitagawa Seiki Kiriyama Junichi Sakagami Atsushi Masamune Kazuo Inui Kenji Hirano Ryukichi Akashi Masamichi Yokoe Yoshio Sogame Kazuichi Okazaki Chie Morioka Yasuyuki Kihara Shigeyuki Kawa Masao Tanaka Akira Andoh Wataru Kimura Isao Nishimori Junji Furuse Isao Yokota Tooru Shimosegawa | 2019 | World Journal of Gastroenterology2019，25，1： | 7 |
| 15 | Atomistics of superlubricity显示文摘Friction is a phenomenon observed ubiquitously in daily life,yet its nature is complicated.Friction between rough surfaces is considered to arise primarily because of macroscopic roughness.In contrast,interatomic forces dominate between clean and smooth surfaces.“Superlubricity”,where friction effectively becomes zero,occurs when the ratio of lattice parameters in the pair of surfaces becomes an irrational number.Superlubricity has been found to exist in a limited number of systems,but is a very important phenomenon both in industry and in mechanical engineering.New atomistic research on friction is under way,with the aim of refining theoretical models that consider interactions between atoms beyond mean field theory and experiments using ultrahigh vacuum non-contact atomic force microscopy.Such research is expected to help clarify the nature of microscopic friction,reveal the onset conditions of friction and superlubricity as well as the stability of superlubricity,discover new superlubric systems,and lead to new applications. | Motohisa HIRANO | 2014 | Friction2014，2，2： | 7 |
| 16 | Combined choriocarcinoma, neuroendocrine cell carcinoma and tubular adenocarcinoma in the stomach显示文摘We described a patient with adenocarcinoma of the stomach combined with choriocarcinoma and neuroendocrine cell carcinoma. An 85-year-old man visited our hospital because of appetite loss. Gastric fiberscopy revealed a large tumor occupying the cardial region and anterior wall of the gastric body. The patient underwent total gastrectomy with lymphnode dissection and partial resection of the liver. Choriocarcinoma, small cell carcinoma and tubular adenocarcinoma existed in the gastric tumor. The choriocarcinomatous foci contained cells positive for beta-subunit of human chorionic gonadotropin (B-hCG) and human placental lactogen mainly in syncytiotrophoblastic cells. The small cell carcinomatous foci contained cells positive for synaptophysin, neuron-specific enolase (NSE), and chromogranin A. The prognosis for gastric adenocarcinoma with choriocarcinoma and neuroendocrine cell carcinoma is exceedingly poor. This patient died about 2 mo after the first complaint from hepatic failure. This is the first reported case of gastric cancer with these three pathological features. | Yasumitsu Hirano Takuo Hara Hiroshi Nozawa Kaeko Oyama Naohiro Ohta Kenji Omura Go Watanabe Hideki Niwa | 2008 | World Journal of Gastroenterology2008，14，20： | 6 |
| 17 | Advances in diagnostic testing for gastroesophageal reflux disease显示文摘Gastroesophageal reflux disease (GERD) contributes substantially to morbidity and to costs in the United States health care system. The burden of this disease has resulted in attempts at improving diagnosis and characterizing patients. Numerous research and technical advances have enhanced our understanding of both the utility and limitations of a variety of diagnostic modalities. The purpose of this review is to highlight recent advances in GERD diagnostic testing and to discuss their implications for use in clinical practice. Topics addressed include esophageal pH monitoring, impedance testing, symptom association analyses, narrow-band imaging, and histopathology. | Andrew J Gawron Ikuo Hirano | 2010 | World Journal of Gastroenterology2010，16，30： | 6 |
| 18 | Measurement of prostaglandin metabolites is useful in diagnosis of small bowel ulcerations显示文摘BACKGROUND We recently reported on a hereditary enteropathy associated with a gene encoding a prostaglandin transporter and referred to as chronic enteropathy associated with SLCO2 A1 gene(CEAS). Crohn's disease(CD) is a major differential diagnosis of CEAS, because these diseases share some clinical features. Therefore, there is a need to develop a convenient screening test to distinguish CEAS from CD.AIM To examine whether prostaglandin E major urinary metabolites(PGE-MUM) can serve as a biomarker to distinguish CEAS from CD.METHODS This was a transactional study of 20 patients with CEAS and 98 patients with CD.CEAS was diagnosed by the confirmation of homozygous or compound heterozygous mutation of SLCO2 A1. We measured the concentration of PGEMUM in spot urine by radioimmunoassay, and the concentration was compared between the two groups of patients. We also determined the optimal cut-off value of PGE-MUM to distinguish CEAS from CD by receiver operating characteristic(ROC) curve analysis.RESULTS Twenty Japanese patients with CEAS and 98 patients with CD were enrolled.PGE-MUM concentration in patients with CEAS was significantly higher than that in patients with CD(median 102.7 vs 27.9 μg/g × Cre, P < 0.0001). One log unit increase in PGE-MUM contributed to 7.3 increase in the likelihood for the diagnosis of CEAS [95% confidence interval(CI) 3.2-16.7]. A logistic regression analysis revealed that the association was significant even after adjusting confounding factors(adjusted odds ratio 29.6, 95%CI 4.7-185.7). ROC curve analysis revealed the optimal PGE-MUM cut-off value for the distinction of CEAS from CD to be 48.9 μg/g × Cre with 95.0% sensitivity and 79.6% specificity.CONCLUSION PGE-MUM measurement is a convenient, non-invasive and useful test for the distinction of CEAS from CD. | Yuichi Matsuno Junji Umeno Motohiro Esaki Yoichiro Hirakawa Yuta Fuyuno Yasuharu Okamoto Atsushi Hirano Shigeyoshi Yasukawa Fumihito Hirai Toshiyuki Matsui Shuhei Hosomi Kenji Watanabe Naoki Hosoe Haruhiko Ogata Tadakazu Hisamatsu Shunichi Yanai Shuji Kochi Koichi Kurahara Tsuneyoshi Yao Takehiro Torisu Takanari Kitazono Takayuki Matsumoto | 2019 | World Journal of Gastroenterology2019，25，14： | 5 |
| 19 | Giant primary angiosarcoma of the small intestine showing severe sepsis显示文摘Primary malignant tumors of the small intestine are rare,comprising less than 2%of all gastrointestinal tumors.An 85-year-old woman was admitted with fever of 40℃ and marked abdominal distension.Her medical history was unremarkable,but blood examination showed elevated inflammatory markers.Abdominal computed tomography showed a giant tumor with central necrosis,extending from the epigastrium to the pelvic cavity.Giant gastrointestinal stromal tumor of the small intestine communicating with the gastrointestinal tract or with superimposed infection was suspected.Because no improvement occurred in response to antibiotics,surgery was performed.Laparotomy revealed giant hemorrhagic tumor adherent to the small intestine and occupying the peritoneal cavity.The giant tumor was a solid tumor weighing 3490 g,measuring24 cm×17.5 cm×18 cm and showing marked necrosis.Histologically,the tumor comprised spindle-shaped cells with anaplastic large nuclei.Immunohistochemical studies showed tumor cells positive for vimentin,CD31,and factorⅧ-related antigen,but negative for c-kit and CD34.Angiosarcoma was diagnosed.Although no postoperative complications occurred,the patient experienced enlargement of multiple metastatic tumors in the abdominal cavity and died 42 d postoperatively.The prognosis of small intestinal angiosarcoma is very poor,even after volume-reducing palliative surgery. | Mizuna Takahashi Masanori Ohara Noriko Kimura Hiromitsu Domen Takumi Yamabuki Kazuteru Komuro Takahiro Tsuchikawa Satoshi Hirano Nozomu Iwashiro | 2014 | World Journal of Gastroenterology2014，20，43： | 5 |
| 20 | Factors associated with residual gastroesophageal reflux disease symptoms in patients receiving proton pump inhibitor maintenance therapy显示文摘AIM To elucidate the factors associated with residual gastroesophageal reflux disease(GERD) symptoms in patients receiving proton pump inhibitor(PPI) maintenance therapy in clinical practice.METHODS The study included 39 GERD patients receiving maintenance PPI therapy. Residual symptoms were assessed using the Frequency Scale for Symptoms of GERD(FSSG) questionnaire and the Gastrointestinal Symptom Rating Scale(GSRS). The relationships between the FSSG score and patient background factors, including the CYP2C19 genotype, were analyzed.RESULTS The FSSG scores ranged from 1 to 28 points(median score: 7.5 points), and 19 patients(48.7%) had a score of 8 points or more. The patients' GSRS scores were significantly correlated with their FSSG scores(correlation coefficient = 0.47, P < 0.005). In erosive esophagitis patients, the FSSG scores of the CYP2C19 rapid metabolizers(RMs) were significantly higher than the scores of the poor metabolizers and intermediate metabolizers(total scores: 16.7 ± 8.6 vs 7.8 ± 5.4, P < 0.05; acid reflux-related symptom scores: 12 ± 1.9 vs 2.5 ± 0.8, P < 0.005). In contrast, the FSSG scores of the CYP2C19 RMs in the non-erosive reflux disease patients were significantly lower than those of the other patients(total scores: 5.5 ± 1.0 vs 11.8 ± 6.3, P < 0.05; dysmotility symptom-related scores: 1.0 ± 0.4 vs 6.0 ± 0.8, P < 0.01). CONCLUSION Approximately half of the GERD patients receiving maintenance PPI therapy had residual symptoms associated with a lower quality of life, and the CYP2C19 genotype appeared to be associated with these residual symptoms. | Fumiaki Kawara Tsuyoshi Fujita Yoshinori Morita Atsushi Uda Atsuhiro Masuda Masaya Saito Makoto Ooi Tsukasa Ishida Yasuyuki Kondo Shiei Yoshida Tatsuya Okuno Yoshihiko Yano Masaru Yoshida Hiromu Kutsumi Takanobu Hayakumo Kazuhiko Yamashita Takeshi Hirano Midori Hirai Takeshi Azuma | 2017 | World Journal of Gastroenterology2017，23，11： | 5 |
