| 1 | Clinical features of gastroduodenal injury associated with long-term low-dose aspirin therapy显示文摘Low-dose aspirin(LDA) is clinically used for the prevention of cardiovascular and cerebrovascular events with the advent of an aging society.On the other hand,a very low dose of aspirin(10 mg daily) decreases the gastric mucosal prostaglandin levels and causes significant gastric mucosal damage.The incidence of LDAinduced gastrointestinal mucosal injury and bleeding has increased.It has been noticed that the incidence of LDA-induced gastrointestinal hemorrhage has increased more than that of non-aspirin non-steroidal anti-inflammatory drug(NSAID)-induced lesions.The pathogenesis related to inhibition of cyclooxygenase(COX)-1 includes reduced mucosal flow,reduced mucus and bicarbonate secretion,and impaired platelet aggregation.The pathogenesis related to inhibition of COX-2 involves reduced angiogenesis and increased leukocyte adherence.The pathogenic mechanisms related to direct epithelial damage are acid back diffusion and impaired platelet aggregation.The factors associated with an increased risk of upper gastrointestinal(GI) complications in subjects taking LDA are aspirin dose,history of ulcer or upper GI bleeding,age > 70 years,concomitant use of non-aspirin NSAIDs including COX-2-selective NSAIDs,and Helicobacter pylori(H.pylori) infection.Moreover,no significant differences have been found between ulcer and non-ulcer groups in the frequency and severity of symptoms such as nausea,acid regurgitation,heartburn,and bloating.It has been shown that the ratios of ulcers located in the body,fundus and cardia are significantly higher in bleeding patients than the ratio of gastroduodenal ulcers in patients taking LDA.Proton pump inhibitors reduce the risk of developing gastric and duodenal ulcers.In contrast to NSAIDinduced gastrointestinal ulcers,a well-tolerated histamine H2-receptor antagonist is reportedly effective in prevention of LDA-induced gastrointestinal ulcers.The eradication of H.pylori is equivalent to treatment with omeprazole in preventing recurrent bleeding.Continuous aspirin therapy for patients with gastrointestinal bleeding may increase the risk of recurrent bleeding but potentially reduces the mortality rates,as stopping aspirin therapy is associated with higher mortality rates.It is very important to prevent LDA-induced gastroduodenal ulcer complications including bleeding,and every effort should be exercised to prevent the bleeding complications. | Junichi Iwamoto Yoshifumi Saito Akira Honda Yasushi Matsuzaki | 2013 | World Journal of Gastroenterology2013，19，11： | 29 |
| 2 | Genistein inhibits invasive potential of human hepatocellular carcinoma by altering cell cycle, apoptosis, and angiogenesis显示文摘AIM: To study the in vitro and in vivo inhibitory effects of genistein on invasive potential of Bel 7402 hepatocellular carcinoma (HCC) cells and to explore the underlying mechanism.METHODS: Bel 7402 HCC cells were exposed to genistein. The invasive activity of tumor cells was assayed in transwell cell culture chamber. p125FAK expression and cell cycle were evaluated by a functional assay. Cell apoptosis analysis was performed with TUNEL method. In addition, bilateral subrenal capsule xenograft transplantation of HCC was performed in 10 nude mice.Genistein was injected and the invasion of HCC into the renal parenchyma was observed. Microvessels with immunohistochemical staining were detected.RESULTS: Genistein significantly inhibited the growth of Bel 7402 cells, the inhibitory rate of tumor cells was 26 -42%. The invasive potential of Bel 7402 cells in vitro was significantly inhibited, the inhibitory rate was 11-28%. Genistein caused G2/M cell cycle arrest, S phase decreased significantly. The occurrence of apoptosis in genistein group increased significantly. The expression of p125FAK in 5 μg/mL genistein group (15.26±0.16%)and 10 μg/mL genistein group (12.89±0.36%) was significantly lower than that in the control group (19.75± 1.12%,P<0.05). Tumor growth in genistein-treated nude mice was significantly retarded in comparison to control mice, the inhibitory rate of tumor growth was about 20%. Genistein also significantly inhibited the invasion of Bel 7402 cells into the renal parenchyma of nude mice with xenograft transplant. The positive unit value of microvessels in genistein-treated group (10.422±0.807)was significantly lower than that in control group (22.330 ± 5.696, P< 0.01).CONCLUSION: Genistein can effectively inhibit the invasive potential of Bel 7402 HCC cells by altering cell cycle, apoptosis and angiogenesis, inhibition of focal adhesion kinase may play a significant role in this process. | Yan Gu Chen-Fang Zhu Hitoshi Iwamoto Ji-Sheng Chen | 2005 | World Journal of Gastroenterology2005，11，41： | 13 |
| 3 | Effectiveness of exercise for osteoarthritis of the knee:A review of the literature显示文摘Osteoarthritis(OA)of the knee is the most common type of arthritis and the major cause of chronic musculoskeletal pain and mobility disability in the elderly.The objective of this paper is to discuss the effectiveness of exercise for OA of the knee based on a review of the literature.We reviewed the relevant literature,i.e.systematic reviews and meta-analyses searched using PubMed.Muscle strengthening and aerobic exercises are effective in reducing pain and improving physical function in patients with mild to moderate OA of the knee. | Jun Iwamoto Yoshihiro Sato Tsuyoshi Takeda Hideo Matsumoto | 2011 | World Journal of Orthopedics2011，2，5： | 11 |
| 4 | Treatment strategies for advanced hepatocellular carcinoma:Sorafenib vs hepatic arterial infusion chemotherapy显示文摘Sorafenib is used worldwide as a first-line standardsystemic agent for advanced hepatocellular carcinoma(HCC) on the basis of the results of two large-scale Phase Ⅲ trials. Conversely,hepatic arterial infusion chemotherapy(HAIC) is one of the most recommended treatments in Japan. Although there have been no randomized controlled trials comparing sorafenib with HAIC,several retrospective analyses have shown no significant differences in survival between the two therapies. Outcomes are favorable for HCC patients exhibiting macroscopic vascular invasion when treated with HAIC rather than sorafenib,whereas in HCC patients exhibiting extrahepatic spread or resistance to transcatheter arterial chemoembolization,good outcomes are achieved by treatment with sorafenib rather than HAIC. Additionally,sorafenib is generally used to treat patients with Child-Pugh A,while HAIC is indicated for those with either Child-Pugh A or B. Based on these findings,we reviewed treatment strategies for advanced HCC. We propose that sorafenib might be used as a first-line treatment for advanced HCC patients without macroscopic vascular invasion or Child-Pugh A,while HAIC is recommended for those with macroscopic vascular invasion or Child-Pugh A or B. Additional research is required to determine the best second-line treatment for HAIC non-responders with Child-Pugh B through future clinical trials. | Issei Saeki Takahiro Yamasaki Masaki Maeda Takuro Hisanaga Takuya Iwamoto Koichi Fujisawa Toshihiko Matsumoto Isao Hidaka Yoshio Marumoto Tsuyoshi Ishikawa Naoki Yamamoto Yutaka Suehiro Taro Takami Isao Sakaida | 2018 | World Journal of Hepatology2018，10，9： | 10 |
| 5 | Small-bowel mucosal injuries in low-dose aspirin users with obscure gastrointestinal bleeding显示文摘AIM: To investigate the clinical differences between small intestinal injuries in low-dose aspirin(LDA) users and in non-steroidal anti-inflammatory drug(NSAID) users who were examined by capsule endoscopy(CE) for obscure gastrointestinal bleeding(OGIB). METHODS: A total of 181 patients who underwent CE for OGIB were included in this study. Based on clinical records, laboratory data such as hemoglobin levels, major symptoms, underlying diseases, the types and duration of LDA and NSAID use, and endoscopic characteristics of CE were reviewed.RESULTS: Out of a total of 45 cases of erosive lesions, 27 cases were taking LDA or NSAIDs(7 were on NSAIDs, 9 were on LDA alone, 9 were on LDA and thienopyridine, and 2 were on LDA and warfarin).The prevalence of ulcers or erosion during chronic use of LDA, LDA and the anti-platelet drug thienopyridine (clopidogrel or ticlopidine), and NSAIDs were 64.3%, 80.0%, and 75.0%, respectively. Erosive lesions were observed predominantly in chronic LDA users, while ulcerative lesions were detected mainly in NSAID users. However, concomitant use of thienopyridine such as clopidogrel with LDA increased the proportion of ulcers. The erosive lesions were located in the whole of the small intestine(jejunum and ileum), whereas ulcerative lesions were mainly observed in the ileum(P < 0.05). CONCLUSION: Our CE findings indicate that chronic LDA users and NSAID users show different types and locations of small-bowel mucosal injuries. The concomitant use of anti-platelet drugs with LDA tends to exacerbate the injuries from LDA-type to NSAID-type injuries. | Junichi Iwamoto Yuji Mizokami Yoshifumi Saito Koichi Shimokobe Akira Honda Tadashi Ikegami Yasushi Matsuzaki | 2014 | World Journal of Gastroenterology2014，20，36： | 9 |
| 6 | Clinical outcomes of enteroscopy using the double-balloon method for strictures of the small intestine显示文摘AIM: To evaluate the clinical outcome of enteroscopy, using the double-balloon method, focusing on the involvement of neoplasms in strictures of the small intestine.METHODS: Enteroscopy, using the double-balloon method, was performed between December 1999 and December 2002 at Jichi Medical School Hospital, Japan and strictures of the small intestine were found in 17 out of 62 patients. These 17 consecutive patients were subjected to analysis.RESULTS: The double-balloon enteroscopy contributed to the diagnosis of small intestinal neoplasms found in 3out of 17 patients by direct observation of the strictures as well as biopsy sampling. Surgical procedures were chosen for these three patients, while balloon dilation was chosen for the strictures in four patients diagnosed with inflammation without involvement of neoplasm.CONCLUSION: Double-balloon enteroscopy is a useful method for the diagnosis and treatment of strictures in the small bowel. | Keijiro Sunada Hironori Yamamoto Hiroto Kita Tomonori Yano Hiroyuki Sato Yoshikazu Hayashi Tomohiko Miyata Yutaka Sekine Akiko Kuno Michiko Iwamoto Hirohide Ohnishi Kenichi Ido Kentaro Sugano | 2005 | World Journal of Gastroenterology2005，11，7： | 6 |
| 7 | Non-steroidal anti-inflammatory drug-induced small bowel injuries identified by double-balloon endoscopy显示文摘AIM: To clarify clinical features of the NSAID-induced small bowel lesions using a new method of endoscopy.METHODS: This is a retrospective study and we analyzed seven patients with small bowel lesions while taking NSAIDs among 61 patients who had undergone doubleballoon endoscopy because of gastro-intestinal bleeding or anemia between September 2000 and March 2004, at Jichi Medical School Hospital in Japan. Neither conventional EGD nor colonoscopy revealed any lesions of potential bleeding sources including ulcerations. Double-balloon endoscopy was carried out from oral approach in three patients, from anal approach in three patients, and from both approaches in one patient.RESULTS: Ulcers or erosions were observed in the ileum in six patients and in the jejunum in one patient, respectively.The ulcers were multiple in all the patients with different features from tiny punched out ulcers to deep ulcerations with oozing hemorrhage or scar. All the patients recovered uneventfully and had full resolution of symptoms after suspension of the drug.CONCLUSION: NSAIDs can induce injuries in the small bowel even in patients without any lesions in both the stomach and colon. | Yoshikazu Hayashi Hironori Yamamoto Hiroto Kita Keijiro Sunada Hiroyuki Sato Tomonori Yano Michiko Iwamoto Yutaka Sekine Tomohiko Miyata Akiko Kuno Takaaki Iwaki Yoshiyuki Kawamura Hironari Ajibe Kenichi Ido Kentaro Sugano | 2005 | World Journal of Gastroenterology2005，11，31： | 6 |
| 8 | Water-saving irrigation of paddy field to reduce nutrient runoff显示文摘The purpose of this work is to study the effect of a type of water-saving irrigation (WSI) on nutrient runoff of paddy field.The volume of surface drainage was maintained low by WSI.In particular,WSI effectively reduced surface drainage in rain events.Model simulation indicated that net runoff load of total nitrogen (TN) from the paddy field was increased by WSI.Meanwhile,net runoff loads of total phosphorus (TP) and total organic carbon (TOC) from the paddy field was decreased by WSI.Because ponding waters of the study fields were enriched with TP and TOC,WSI reduced runoff of these nutrients by controlling the volume of surface drainage.WSI could be considered an efficient method for reducing runoff loads and could conserve water quality in an agricultural watershed. | Tadayoshi Hitomi Yusaku Iwamoto Asa Miura Koji Hamada Kyoji Takaki Eisaku Shiratani | 2010 | Journal of Environmental Sciences2010，22，6： | 6 |

| 10 | Anterolateral rotatory instability in vivo correlates tunnel position after anterior cruciate ligament reconstruction using bone-patellar tendon-bone graft显示文摘AIM To quantitatively assess rotatory and anterior-posterior instability in vivo after anterior cruciate ligament(ACL) reconstruction using bone-patellar tendon-bone(BTB) autografts, and to clarify the influence of tunnel positions on the knee stability.METHODS Single-bundle ACL reconstruction with BTB autograft was performed on 50 patients with a mean age of 28 years using the trans-tibial(TT)(n = 20) and trans-portal(TP)(n = 30) techniques. Femoral and tibial tunnel positions were identified from the high-resolution 3 D-CT bone models two weeks after surgery. Anterolateral rotatory translation was examined using a Slocum anterolateral rotatory instability test in open magnetic resonance imaging(MRI) 1.0-1.5 years after surgery, by measuring anterior tibial translation at the medial and lateral compartments on its sagittal images. Anterior-posterior stability was evaluated with a Kneelax3 arthrometer.RESULTS A total of 40 patients(80%) were finally followed up. Femoral tunnel positions were shallower(P < 0.01) and higher(P < 0.001), and tibial tunnel positions were more posterior(P < 0.05) in the TT group compared with the TP group. Anterolateral rotatory translations in reconstructed knees were significantly correlated with the shallow femoral tunnel positions(R = 0.42, P < 0.01), and the rotatory translations were greater in the TT group(3.2 ± 1.6 mm) than in the TP group(2.0 ± 1.8 mm)(P < 0.05). Side-to-side differences of Kneelax3 arthrometer were 1.5 ± 1.3 mm in the TT, and 1.7 ± 1.6 mm in the TP group(N.S.). Lysholm scores, KOOS subscales and reinjury rate showed no difference between the two groups.CONCLUSION Anterolateral rotatory instability significantly correlated shallow femoral tunnel positions after ACL reconstruction using BTB autografts. Clinical outcomes, rotatory and anterior-posterior stability were overall satisfactory in both techniques, but the TT technique located femoral tunnels in shallower and higher positions, and tibial tunnels in more posterior positions than the TP technique, thus increased the anterolateral rotation. Anatomic ACL reconstruction with BTB autografts may restore knee function and stability. | Yasutaka Tashiro Ken Okazaki Koji Murakami Hirokazu Matsubara Kanji Osaki Yukihide Iwamoto Yasuharu Nakashima | 2017 | World Journal of Orthopedics2017，8，12： | 5 |
| 11 | Differential effects of physical activity and sleep duration on cognitive function in young adults显示文摘Purpose: Although exercise and sleep duration habits are associated with cognitive function, their beneficial effects on cognitive function remain unclear. We aimed to examine the effect of sleep duration and daily physical activity on cognitive function, elucidating the neural mechanisms using near-infrared spectroscopy(NIRS).Methods: A total of 23 healthy young adults(age 22.0 ± 2.2 years) participated in this study. Exercise amount was assessed using a uniaxial accelerometer. We evaluated total sleep time(TST) and sleep efficiency by actigraphy. Cognitive function was tested using the N-back task, the Wisconsin Card Sorting Test(WCST), and the Continuous Performance Test—Identical Pairs(CPT-IP), and the cortical oxygenated hemoglobin levels during a word fluency task were measured with NIRS.Results: Exercise amount was significantly correlated with reaction time on 0- and 1-back tasks(r = —0.602, p = 0.002; r = —0.446, p = 0.033,respectively), whereas TST was significantly correlated with % corrects on the 2-back task(r = 0.486, p = 0.019). Multiple regression analysis,including exercise amount, TST, and sleep efficiency, revealed that exercise amount was the most significant factor for reaction time on 0- and 1-back tasks(b = —0.634, p = 0.002; b = —0.454, p = 0.031, respectively), and TST was the most significant factor for % corrects on the 2-back task(b = 0.542, p = 0.014). The parameter measured by WCST and CPT-IP was not significantly correlated with TST or exercise amount. Exercise amount, but not TST, was significantly correlated with the mean area under the NIRS curve in the prefrontal area(r = 0.492, p = 0.017).Conclusion: Exercise amount and TST had differential effects on working memory and cortical activation in the prefrontal area. Daily physical activity and appropriate sleep duration may play an important role in working memory. | Kazuko Kato Kunihiro Iwamoto Naoko Kawano Yukihiro Noda Norio Ozaki Akiko Noda | 2018 | Journal of Sport and Health Science2018，7，2： | 5 |
| 12 | Analysis of stress fractures in athletes based on our clinical experience显示文摘AIM:To analyze stress fractures in athletes based on experience from our sports medicine clinic.METHODS:We investigated the association between stress fractures and age,sex,sports level,sports activity,and skeletal site in athletes seen at our sports medicine clinic between September 1991 and April 2009.Stress fractures of the pars interarticularis were excluded from this analysis.RESULTS:During this period(18 years and 8 mo),14276 patients(9215 males and 5061 females)consulted our clinic because of sports-related injuries,and 263 patients(1.8%)[171 males(1.9%)and 92 females(1.8%)]sustained stress fractures.The average age of the patients with stress fractures was 20.2 years(range 10-46 years);112 patients(42.6%)were 15-19 years of age and 90(34.2%)were 20-24 years of age.Altogether,90 patients(34.2%)were active at a high recreational level and 173(65.8%)at a competitive level.The highest proportion of stress fractures was seen in basketball athletes(21.3%),followed by baseball(13.7%),track and field(11.4%),rowing(9.5%),soccer(8.4%),aerobics(5.3%),and classical ballet(4.9%).The most common sites of stress fractures in these patients were the tibia(44.1%),followed by the rib(14.1%),metatarsal bone(12.9%),ulnar olecranon(8.7%)and pelvis(8.4%).The sites of the stress fractures varied from sport to sport.The ulnar olecranon was the most common stress fracture site in baseball players,and the rib was the most common in rowers.Basketball and classical ballet athletes predominantly sustained stress fractures of the tibia and metatarsal bone.Track and field and soccer athletes predominantly sustained stress fractures of the tibia and pubic bone.Aerobics athletes predominantly sustained stress fractures of the tibia.Middle and long distance female runners who sustained multiple stress fractures had the female athlete triad.CONCLUSION:The results of this analysis showed that stress fractures were seen in high-level young athletes,with similar proportions for males and females,and that particular sports were associated with specific sites for stress fractures.Middle and long distance female runners who suffered from multiple stress fractures had the female athlete triad. | Jun Iwamoto Yoshihiro Sato Tsuyoshi Takeda Hideo Matsumoto | 2011 | World Journal of Orthopedics2011，2，1： | 4 |
| 13 | 精力的文学评论为执行 laparoscopic colorectal 外科采购原料显示文摘 Laparoscopic surgery for colorectal disease has become widespread as a minimally invasive treatment.This is important because the increasing availability of new devices allows us to perform procedures with a reduced length of surgery and decreased blood loss.We herein report the results of a literature review of energy sources for laparoscopic colorectal surgery,focused especially on 6 studies comparing ultrasonic coagulating shears(UCS) and other instruments.We also describe our laparoscopic dissection techniques using UCS for colorectal cancer.The short-term outcomes of surgeries using UCS and Ligasure for laparoscopiccolorectal surgery were superior to conventional electrosurgery.Some authors have reported that the length of surgery or blood loss when Ligasure was used for laparoscopic colorectal surgery is less than when UCS was used.On the other hand,a recent study demonstrated that there were no significant differences between the short-term outcomes of UCS and Ligasure for laparoscopic colorectal surgery.It is therefore suggested that the choice of technique used should be made according to the surgeon’s preference.We also describe our laparoscopic dissection techniques using UCS(Harmonic ACE) for colorectal cancer with regard to the retroperitoneum dissection,dissection technique,dissection technique around the feeding artery,and various other dissection techniques.We therefore review the outcomes of using various energy sources for laparoscopic colorectal surgery and describe our laparoscopic dissection techniques with UCS(Harmonic ACE) for colorectal cancer. | Tsukasa Hotta Katsunari Takifuji Shozo Yokoyama Kenji Matsuda Takashi Higashiguchi Toshiji Tominaga Yoshimasa Oku Takashi Watanabe Toru Nasu Tadamichi Hashimoto Koichi Tamura Junji Ieda Naoyuki Yamamoto Hiromitsu Iwamoto Hiroki Yamaue | 2012 | World Journal of Gastrointestinal Surgery2012，4，1： | 4 |

| 16 | Effects of an oral iron chelator, deferasirox, on advanced hepatocellular carcinoma显示文摘AIM To evaluate the inhibitory effects of deferasirox(DFX) against hepatocellular carcinoma(HCC) through basic and clinical studies.METHODS In the basic study, the effect of DFX was investigated in three hepatoma cell lines(Hep G2, Hep3 B, and Huh7), as well as in an N-nitrosodiethylamine-induced murine HCC model. In the clinical study, six advanced HCC patients refractory to chemotherapy were enrolled. The initial dose of DFX was 10 mg/kg per day and was increased by 10 mg/kg per day every week, until the maximum dose of 30 mg/kg per day. The duration of a single course of DFX therapy was 28 consecutive days. In the event of dose-limiting toxicity(according to the Common Terminology Criteria for Adverse Events v.4.0), DFX dose was reduced.RESULTS Administration of DFX inhibited the proliferation of hepatoma cell lines and induced the activation of caspase-3 in a dose-dependent manner in vitro. In the murine model, DFX treatment significantly suppressed the development of liver tumors(P < 0.01), and significantly upregulated the mR NA expression levels of hepcidin(P < 0.05), transferrin receptor 1(P < 0.05), and hypoxia inducible factor-1α(P < 0.05) in both tumor and non-tumor tissues, compared with control mice. In the clinical study, anorexia and elevated serum creatinine were observed in four and all six patients, respectively. However, reduction in DFX dose led to decrease in serum creatinine levels in all patients. After the first course of DFX, one patient discontinued the therapy. We assessed the tumor response in the remaining five patients; one patient exhibited stable disease, while four patients exhibited progressive disease. The one-year survival rate of the six patients was 17%.CONCLUSION We demonstrated that DFX inhibited HCC in the basic study, but not in the clinical study due to dose-limiting toxicities. | Issei Saeki Naoki Yamamoto Takahiro Yamasaki Taro Takami Masaki Maeda Koichi Fujisawa Takuya Iwamoto Toshihiko Matsumoto Isao Hidaka Tsuyoshi Ishikawa Koichi Uchida Kenji Tani Isao Sakaida | 2016 | World Journal of Gastroenterology2016，22，40： | 3 |

| 18 | STAT3 deficiency prevents hepatocarcinogenesis and promotes biliary proliferation in thioacetamide-induced liver injury显示文摘AIM To elucidate the role of STAT3 in hepatocarcinogenesis and biliary ductular proliferation following chronic liver injury. METHODS We investigated thioacetamide(TAA)-induced liver injury, compensatory hepatocyte proliferation, and hepatocellular carcinoma(HCC) development in hepatic STAT3-deficient mice. In addition, we evaluated TAAinduced biliary ductular proliferation and analyzed the activation of sex determining region Y-box9(SOX9) and Yes-associated protein(YAP), which regulate the transdifferentiation of hepatocytes to cholangiocytes.RESULTS Both compensatory hepatocyte proliferation and HCC formation were significantly decreased in hepatic STAT3-deficient mice as compared with control mice. STAT3 deficiency resulted in augmentation of hepatic necrosis and fibrosis. On the other hand, biliary ductular proliferation increased in hepatic STAT3-deficient livers as compared with control livers. SOX9 and YAP were upregulated in hepatic STAT3-deficient hepatocytes.CONCLUSION STAT3 may regulate hepatocyte proliferation as well as transdifferentiation into cholangiocytes and serve as a therapeutic target for HCC inhibition and biliary regeneration. | Mitsuhiko Abe Takafumi Yoshida Jun Akiba Yu Ikezono Fumitaka Wada Atsutaka Masuda Takahiko Sakaue Toshimitsu Tanaka Hideki Iwamoto Toru Nakamura Michio Sata Hironori Koga Akihiko Yoshimura Takuji Torimura | 2017 | World Journal of Gastroenterology2017，23，37： | 2 |
