| 1 | Apoptosis and non-alcoholic fatty liver diseases显示文摘The number of patients with nonalcoholic fatty liver diseases(NAFLD) including nonalcoholic steatohepatitis(NASH), has been increasing. NASH causes cirrhosis and hepatocellular carcinoma(HCC) and is one of the most serious health problems in the world. The mechanism through which NASH progresses is still largely unknown. Activation of caspases, Bcl-2 family proteins, and c-Jun N-terminal kinase-induced hepatocyte apoptosis plays a role in the activation of NAFLD/NASH. Apoptotic hepatocytes stimulate immune cells and hepatic stellate cells toward the progression of fibrosis in the liver through the production of inflammasomes and cytokines. Abnormalities in glucose and lipid metabolism as well as microbiota accelerate these processes. The production of reactive oxygen species, oxidative stress, and endoplasmic reticulum stress is also involved. Cell death, including apoptosis, seems very important in the progression of NAFLD and NASH. Recently, inhibitors of apoptosis have been developed as drugs for the treatment of NASH and may prevent cirrhosis and HCC. Increased hepatocyte apoptosis may distinguish NASH from NAFLD, and the improvement of apoptosis could play a role in controlling the development of NASH. In this review, the association between apoptosis and NAFLD/NASH are discussed. This review could provide their knowledge, which plays a role in seeing the patients with NAFLD/NASH in daily clinical practice. | Tatsuo Kanda Shunichi Matsuoka Motomi Yamazaki Toshikatsu Shibata Kazushige Nirei Hiroshi Takahashi Tomohiro Kaneko Mariko Fujisawa Teruhisa Higuchi Hitomi Nakamura Naoki Matsumoto Hiroaki Yamagami Masahiro Ogawa Hiroo Imazu Kazumichi Kuroda Mitsuhiko Moriyama | 2018 | World Journal of Gastroenterology2018，24，25： | 32 |
| 2 | Does a combined intervention program of repetitive transcranial magnetic stimulation and intensive occupational therapy affect cognitive function in patients with post-stroke upper limb hemiparesis?显示文摘Low-frequency repetitive transcranial magnetic stimulation(LF-r TMS) to the contralesional hemisphere and intensive occupational therapy(i OT) have been shown to contribute to a significant improvement in upper limb hemiparesis in patients with chronic stroke. However, the effect of the combined intervention program of LF-r TMS and i OT on cognitive function is unknown. We retrospectively investigated whether the combined treatment influence patient's Trail-Making Test part B(TMT-B) performance, which is a group of easy and inexpensive neuropsychological tests that evaluate several cognitive functions. Twenty-five patients received 11 sessions of LF-r TMS to the contralesional hemisphere and 2 sessions of i OT per day over 15 successive days. Patients with right- and left-sided hemiparesis demonstrated significant improvements in upper limb motor function following the combined intervention program. Only patients with right-sided hemiparesis exhibited improved TMT-B performance following the combined intervention program, and there was a significant negative correlation between Fugl-Meyer Assessment scale total score change and TMT-B performance. The results indicate the possibility that LF-r TMS to the contralesional hemisphere combined with i OT improves the upper limb motor function and cognitive function of patients with right-sided hemiparesis. However, further studies are necessary to elucidate the mechanism of improved cognitive function. | Takatoshi Hara Masahiro Abo Kiyohito Kakita Takeshi Masuda Ryunosuke Yamazaki | 2016 | Neural Regeneration Research2016，11，12： | 18 |
| 3 | Endoscopy vs surgery in the treatment of early gastric cancer:Systematic review显示文摘AIM: To report a systematic review,establishing the available data to an unpublished 2a strength of evidence,better handling clinical practice.METHODS: A systematic review was performed using MEDLINE,EMBASE,Cochrane,LILACS,Scopus and CINAHL databases. Information of the selected studies was extracted on characteristics of trial participants,inclusion and exclusion criteria,interventions(mainly,mucosal resection and submucosal dissection vs surgical approach) and outcomes(adverse events,different survival rates,mortality,recurrence and complete resection rates). To ascertain the validity of eligible studies,the risk of bias was measured using the Newcastle-Ottawa Quality Assessment Scale. The analysis of the absolute risk of the outcomes was performed using the software Rev Man,by computingrisk differences(RD) of dichotomous variables. Data on RD and 95%CIs for each outcome were calculated using the Mantel-Haenszel test and inconsistency was qualified and reported in χ2 and the Higgins method(I2). Sensitivity analysis was performed when heterogeneity was higher than 50%,a subsequent assay was done and other findings were compiled.RESULTS: Eleven retrospective cohort studies were selected. The included records involved 2654 patients with early gastric cancer that filled the absolute or expanded indications for endoscopic resection. Threeyear survival data were available for six studies(n = 1197). There were no risk differences(RD) after endoscopic and surgical treatment(RD = 0.01,95%CI:-0.02-0.05,P = 0.51). Five-year survival data(n = 2310) showed no difference between the two groups(RD = 0.01,95%CI:-0.01-0.03,P = 0.46). Recurrence data were analized in five studies(1331 patients) and there was no difference between the approaches(RD = 0.01,95%CI:-0.00-0.02,P = 0.09). Adverse event data were identified in eight studies(n = 2439). A significant difference was detected(RD =-0.08,95%CI:-0.10--0.05,P < 0.05),demonstrating better results with endoscopy. Mortality data were obtained in four studies(n = 1107). There was no difference between the groups(RD =-0.01,95%CI:-0.02-0.00,P = 0.22).CONCLUSION: Three-,5-year survival,recurrence and mortality are similar for both groups. Considering complication,endoscopy is better and,analyzing complete resection data,it is worse than surgery. | André Kondo Eduardo Guimaraes Hourneaux de Moura Wanderley Marques Bernardo Osmar Kenji Yagi Diogo Turiani Hourneaux de Moura Eduardo Turiani Hourneaux de Moura José Gon?alves Pereira Bravo Kendi Yamazaki Paulo Sakai | 2015 | World Journal of Gastroenterology2015，21，46： | 12 |

| 5 | Crosstalk between angiogenesis, cytokeratin-18, and insulin resistance in the progression of non-alcoholic steatohepatitis显示文摘AIM: To elucidate the possible crosstalk between angiogenesis, cytokeratin-18 (CK-18), and insulin resistance (IR) especially in patients with non-alcoholic steatohepatitis (NASH).METHODS: Twenty-eight patients with NASH and 11 with simple fatty liver disease (FL) were enrolled in this study and underwent clinicopathological examination. The measures of angiogenesis, CK-18, and IR employed were CD34-immunopositive vessels, CK-18immunopositive cells, and homeostasis model assessment of IR (HOMA-IR), respectively. The correlations of these factors with NASH were elucidated.RESULTS: Significant development of hepatic neovascularization was observed only in NASH, whereas almost no neovascularization could be observed in FL and healthy liver. The degree of angiogenesis was almost parallel to liver fibrosis development, and both parameters were positively correlated. Similarly, CK-18expression and HOMA-R were signifi cantly increased in NASH as compared with FL and healthy liver. Furthermore, CK-18 and HOMA-IR were also positively correlated with the degree of neovascularization. CONCLUSION: These results indicate that the crosstalk between angiogenesis, CK-18, and IR may play an important role in the onset and progression of NASH. | Mitsuteru Kitade Hitoshi Yoshiji Ryuichi Noguchi Yasuhide Ikenaka Kosuke Kaji Yusaku Shirai Masaharu Yamazaki Masahito Uemura Junichi Yamao Masao Fujimoto Akira Mitoro Masahisa Toyohara Masayoshi Sawai Motoyuki Yoshida Chie Morioka Tatsuhiro Tsujimoto Hideto Kawaratani Hiroshi Fukui | 2009 | World Journal of Gastroenterology2009，15，41： | 9 |
| 6 | Surgical treatment of hepatocellular carcinoma: Evidence-based outcomes显示文摘Surgeons may be severely criticized from the perspective of evidence-based medicine because the majority of surgical publications appear not to be convincing. In the top nine surgical journals in 1996, half of the 175 publications refer to pilot studies lacking a control group, 18% to animal experiments, and only 5% to randomized controlled trials (RCT). There are five levels of clinical evidence:level 1 (randomized controlled trial), level 2 (prospective concurrent cohort study), level 3 (retrospective historical cohort study), level 4 (pre-post study), and level 5 (case report). Recently, a Japanese evidence-based guideline for the surgical treatment of hepatocellular carcinoma (HCC) was made by a committee (Chairman, Professor Makuuchi and five members). We searched the literature using the Medline Dialog System with four Keywords:HCC, surgery, English papers, in the last 20 years. A total of 915 publications were identified systematically reviewed. At the first selection (in which surgery-dominant papers were selected), 478 papers survived. In the second selection (clearly concluded papers), 181 papers survived. In the final selection (clinically significant papers), 100 papers survived. The evidence level of the 100 surviving papers is shown here:level-1 papers (13%), level-2 papers (11%), level-3 papers (52%), and level-4 papers (24%);therefore, there were 24% prospective papers and 76% retrospective papers. Here, we present a part of the guideline on the five main surgical issues:indication to operation, operative procedure, peri-operative care, prognostic factor, and post-operative adjuvant therapy. | Shintaro Yamazaki Tadatoshi Takayama | 2008 | World Journal of Gastroenterology2008，14，5： | 8 |
| 7 | Effects of Chinese herbal medicine on plasma glucose,protein and energy metabolism in sheep显示文摘Background:The use of antibiotics in animal diets is facing negative feedback due to the hidden danger of drug residues to human health.Traditional Chinese herbal medicine has been used to replace antibiotics in the past two decades and played an increasingly important role in livestock production.The present study was carried out to assess the feeding effects of a traditional nourishing Chinese herbal medicine mixture on kinetics of plasma glucose,protein and energy metabolism in sheep.Ruminal fermentation characteristics were also determined.Methods:Four sheep were fed on either mixed hay(MH-diet) or MH-diet supplemented with 2%of Chinese herbal medicine(mixture of Astragalus root,Angelica root and Atractylodes rhizome;CHM-diet) over two 35-day periods using a crossover design.The turnover rate of plasma glucose was measured with an isotope dilution method using[U-^(13)C]glucose.The rates of plasma leucine turnover and leucine oxidation,whole body protein synthesis(WBPS)and metabolic heat production were measured using the[1-^(13)C]leucine dilution and open circuit calorimetry.Results:Body weight gain of sheep was higher(P=0.03) for CHM-diet than for MH-diet.Rumen pH was lower(P=0.02),concentration of rumen total volatile fatty acid tended to be higher(P=0.05) and acetate was higher(P=0.04) for CHM-diet than for MH-diet.Turnover rates of plasma glucose and leucine did not differ between diets.Oxidation rate of leucine tended to be higher(P =0.06) for CHM-diet than for MH-diet,but the WBPS did not differ between diets.Metabolic heat production tended to be greater(P=0.05) for CHM-diet than for MH-diet.Conclusions:The sheep fed on CHM-diet had a higher body weight gain and showed positive impacts on rumen fermentation and energy metabolism without resulting in any adverse response.Therefore,these results suggested that the Chinese herbal medicine mixture should be considered as a potential feed additive for sheep. | Xi Liang Kyota Yamazaki Mohammad Kamruzzaman Xue Bi Arvinda Panthee Hiroaki Sano | 2014 | Journal of Animal Science and Biotechnology2014，5，3： | 8 |

| 11 | Serum autotaxin levels are correlated with hepatic fibrosis and ballooning in patients with non-alcoholic fatty liver disease显示文摘AIM To examine the relationship between serum autotaxin(ATX) concentrations and clinicopathological findings in non-alcoholic fatty liver disease(NAFLD) patients.METHODS One hundred eighty-six NAFLD patients who had undergone liver biopsy between 2008 and 2017 were retrospectively enrolled.Serum samples were collected at the time of biopsy and ATX was measured by enzyme immunoassays.Sera obtained from 160 healthy,nonobese individuals were used as controls.Histological findings were graded according to an NAFLD scoring system and correlations with serum ATX were calculated by Spearman's test.Diagnostic accuracy was evaluated using the area under the receiver operating characteristic curve(AUC).Cut-off values were identified by the Youden index,and the nearest clinically applicable value to the cutoff was considered the optimal threshold for clinical convenience.RESULTS Serum ATX levels were significantly higher in NAFLD patients than in controls(0.86 mg/L vs 0.76 mg/L,P < 0.001) and correlated significantly with ballooning score and fibrosis stage(r = 0.36,P < 0.001 and r = 0.45,P < 0.001,respectively).Such tendencies were stronger in female patients.There were no remarkable relationships between ATX and serum alanine aminotransferase,lipid profiles,or steatosis scores.The AUC values of ATX for predicting the presence of fibrosis(≥ F1),significant fibrosis(≥ F2),severe fibrosis(≥ F3),and cirrhosis(F4),were all more than 0.70 in respective analyses.CONCLUSION Serum ATX levels may at least partially reflect histological severity in NAFLD. | Naoyuki Fujimori Takeji Umemura Takefumi Kimura Naoki Tanaka Ayumi Sugiura Tomoo Yamazaki Satoru Joshita Michiharu Komatsu Yoko Usami Kenji Sano Koji Igarashi Akihiro Matsumoto Eiji Tanaka | 2018 | World Journal of Gastroenterology2018，24，11： | 6 |
| 12 | Mild drinking habit is a risk factor for hepatocarcinogenesis in non-alcoholic fatty liver disease with advanced fibrosis显示文摘AIM The impact of mild drinking habit(less than 20 g/d of ethanol) on the clinical course of non-alcoholic fatty liver disease(NAFLD) has not been determined. We examined the influence of a mild drinking habit on liver carcinogenesis from NAFLD. METHODS A total of 301 patients who had been diagnosed as having NAFLD by liver biopsy between 2003 and 2016 [median age: 56 years, 45% male, 56% with nonalcoholic steatohepatitis, 26% with advanced fibrosis(F3-4)] were divided into the mild drinking group withe thanol consumption of less than 20 g/d(mild drinking group, n = 93) and the non-drinking group(n = 208). Clinicopathological features at the time of liver biopsy and factors related to hepatocellular carcinoma(HCC) occurrence were compared between the groups.RESULTS We observed significant differences in male prevalence(P = 0.01), platelet count(P = 0.04), and gammaglutamyl transpeptidase(P = 0.02) between the test groups. Over 6 years of observation, the HCC appearance rate was significantly higher in the mild drinking group(6.5% vs 1.4%, P = 0.02). Multivariate survival analysis using Cox's regression model revealed that hepatic advanced fibrosis(F3-4)(P < 0.01, risk ratio: 11.60), diabetes mellitus(P < 0.01, risk ratio: 89.50), and serum triglyceride(P = 0.04, risk ratio: 0.98) were factors significantly related to HCC in all NAFLD patients, while the effect of a drinking habit was marginal(P = 0.07, risk ratio: 4.43). In patients with advanced fibrosis(F3-4), however, a drinking habit(P = 0.04, risk ratio: 4.83), alpha-fetoprotein(P = 0.01, risk ratio: 1.23), and diabetes mellitus(P = 0.03, risk ratio: 12.00) were identified as significant contributors to HCC occurrence. CONCLUSION A mild drinking habit appears to be a risk factor for hepatocarcinogenesis in NAFLD patients, especially those with advanced fibrosis. | Takefumi Kimura Naoki Tanaka Naoyuki Fujimori Ayumi Sugiura Tomoo Yamazaki Satoru Joshita Michiharu Komatsu Takeji Umemura Akihiro Matsumoto Eiji Tanaka | 2018 | World Journal of Gastroenterology2018，24，13： | 6 |
| 13 | Sustained Type I interferon signaling as a mechanism of resistance to PD-1 blockade显示文摘PD-1 blockade represents a major therapeutic avenue in anticancer immunotherapy.Delineating mechanisms of secondary resistance to this strategy is increasingly important.Here,we identified the deleterious role of signaling via the type I interferon(IFN)receptor in tumor and antigen presenting cells,that induced the expression of nitric oxide synthase 2(N0S2),associated with intratumor accumulation of regulatory T cells(Treg)and myeloid cells and acquired resistance to anti-PD-1 monoclonal antibody(mAb).Sustained IFNP transcription was observed in resistant tumors,in turn inducing PD-L1 and N0S2 expression in both tumor and dendritic cells(DC).Whereas PD-L1 was not involved in secondary resistance to anti-PD-1 mAb,pharmacological or genetic inhibition of N0S2 maintained long-term control of tumors by PD-1 blockade,through reduction of Treg and DC activation.Resistance to immunotherapies,including anti-PD-1 mAb in melanoma patients,was also correlated with the induction of a type I IFN signature.Hence,the role of type I IFN in response to PD-1 blockade should be revisited as sustained type I IFN signaling may contribute to resistance to therapy. | Nicolas Jacquelot Takahiro Yamazaki Maria PRoberti Connie PMDuong Miles CAndrews Loic Verlingue Gladys Ferrere Sonia Becharef Marie Vetizou Romain Daillere Meriem Messaoudene David PEnot Gautier Stoll Stefano Ugel Maria Marigo Shin Foong Ngiow Aurelien Marabelle Armelle Prevost-Blondel Pierre-Olivier Gaudreau Vancheswaran Gopalakrishnan Alexander MEggermont Paule Opolon Christophe Klein Gabriele Madonna Paolo AAscierto Antje Sucker Dirk Schadendorf Mark JSm yth Jean-Charles Soria Guido Kroemer Vincenzo Bronte Jennifer Wargo and Laurence Zitvogel | 2019 | Cell Research2019，29，10： | 6 |
| 14 | Association between endotoxemia and histological features of nonalcoholic fatty liver disease显示文摘AIM To assess whether surrogate biomarkers of endotoxemia were correlated with the histological features ofnonalcoholic fatty liver disease(NAFLD).METHODS One hundred twenty-six NAFLD patients who had undergone percutaneous liver biopsy were enrolled. Serum lipopolysaccharide(LPS)-binding protein(LBP) and anti-endotoxin core immunoglobulin G(Endo Cab Ig G) antibody concentrations at the time of liver biopsy were measured using the enzyme-linked immunosorbent assays to examine for relationships between biomarker levels and histological scores. RESULTS Serum LBP concentration was significantly increased in nonalcoholic steatohepatitis(NASH) patients as compared with nonalcoholic fatty liver(NAFL) subjects and was correlated with steatosis(r = 0.38, P < 0.0001) and ballooning scores(r = 0.23, P = 0.01), but not with the severity of lobular inflammation or fibrosis. Multivariate linear regression analysis revealed that LBP was associated with steatosis score and circulating C-reactive protein, aspartate aminotransferase, and fibrinogen levels. Serum Endo Cab Ig G concentration was comparable between NASH and NAFL patients. No meaningful correlations were detected between Endo Cab Ig G and histological findings. CONCLUSION LBP/Endo Cab Ig G were not correlated with lobular inflammation or fibrosis. More accurate LPS biomarkers are required to stringently assess the contribution of endotoxemia to conventional NASH. | Hiroyuki Kitabatake Naoki Tanaka Naoyuki Fujimori Michiharu Komatsu Ayaka Okubo Kyogo Kakegawa Takefumi Kimura Ayumi Sugiura Tomoo Yamazaki Soichiro Shibata Yuki Ichikawa Satoru Joshita Takeji Umemura Akihiro Matsumoto Masayoshi Koinuma Kenji Sano Toshifumi Aoyama Eiji Tanaka | 2017 | World Journal of Gastroenterology2017，23，4： | 5 |
| 15 | Hypoxia-inducible factor 1 alpha and vascular endothelial growth factor overexpression in ischemic colitis显示文摘AIM: To examine the etiology and pathophysiology in human ischemic colitis from the viewpoint of ischemic favors such as hypoxia-inducible factor 1 alpha (HIF-1alpha and vascular endothelial growth factor (VEGF).METHODS: Thirteen patients with ischemic colitis and 21 normal controls underwent colonoscopy. The follow-up colonoscopy was performed in 8 patients at 7 to 10 d after theoccurrence of ischemic colitis. Biopsy samples were subjected to real-time RT-PCR and immunohistochemistry to detect the expression of HIF-1 alpha and VEGF.RESULTS: HIF-1 alpha and VEGF expression were found in the normal colon tissues by RT-PCR and immunohistochemistry.HIF-1 alpha and VEGF were overexpressed in the lesions of ischemic colitis. Overexpressed HIF-1 alpha and VEGF RNA quickly decreased to the normal level in the scar regions at 7 to 10 d after the occurrence of ischemic colitis.CONCLUSION: Constant expression of HIF-1 alpha and VEGF in normal human colon tissue suggested that HIF-1alpha and VEGF play an important role in maintaining tissue integrity. We confirmed the ischemic crisis in ischemic colitis at the molecular level, demonstrating overexpression of HIF-1 alpha and VEGF in ischemic lesions. These ischemic factors may play an important role in the pathophysiology of ischemic colitis. | Tomoyuki Okuda Takeshi Azuma Masahiro Ohtani Ryuho Masaki Yoshiyuki Ito Yukinao Yamazaki Shigeji Ito Masaru Kuriyama | 2005 | World Journal of Gastroenterology2005，11，10： | 5 |
| 16 | Detection of fusion gene in cell-free DNA of a gastric synovial sarcoma显示文摘Synovial sarcoma(SS) is genetically characterized by chromosomal translocation, which generates SYT-SSX fusion transcripts. Although SS can occur in any body part, primary gastric SS is substantially rare. Here we describe a detection of the fusion gene sequence of gastric SS in plasma cell-free DNA(cf DNA). A gastric submucosal tumor was detected in the stomach of a 27-year-old woman and diagnosed as SS. Candidate intronic primers were designed to detect the intronic fusion breakpoint and this fusion sequence was confirmed in intron 10 of SYT and intron 5 of SSX2 by genomic polymerase chain reaction(PCR) and direct sequencing. A locked nucleic acid(LNA) probe specificto the fusion sequence was designed for detecting the fusion sequence in plasma and the fusion sequence was detected in preoperative plasma cfD NA, while not detected in postoperative plasma cfD NA. This technique will be useful for monitoring translocation-derived diseases such as SS. | Shinpei Ogino Hirotaka Konishi Daisuke Ichikawa Junichi Hamada Katsutoshi Shoda Tomohiro Arita Shuhei Komatsu Atsushi Shiozaki Kazuma Okamoto Sanae Yamazaki Satoru Yasukawa Eiichi Konishi Eigo Otsuji | 2018 | World Journal of Gastroenterology2018，24，8： | 5 |
| 17 | Combined treatment of vitamin K_2 and angiotensin-converting enzyme inhibitor ameliorates hepatic dysplastic nodule in a patient with liver cirrhosis显示文摘Although it is well known that the hepatocellular carcinoma (HCC) is an ominous complication in patients with liver cirrhosis, there has been no approved drug to prevent the development of HCC to date. We previously reported that the combined treatment of vitamin K2 (VK) and angiotensin-converting enzyme inhibitor (ACE-I) significantly suppressed the experimental hepatocarcinogenesis. A 66-year-old Japanese woman with hepatitis C virus (HCV)-related liver cirrhosis developed a dysplastic nodule in the liver detected by enhanced computed tomography along with elevation of the tumor markers, namely, alpha-fetoprotein (AFP) and lectin-reactive demarcation (AFP-L3), suggesting the presence of latent HCC. After oral administration of VK and ACE-I, the serum levels of both AFP and AFP-L3 gradually decreased without any marked alteration of the serum aminotransferase activity. After one-year treatment, not only the serum levels of AFP and AFP-L3 returned to the normal ranges, but also the dysplastic nodule disappeared. Since both VK and ACE-I are widely used without serious side effects, this combined regimen may become a new strategy for chemoprevention against HCC. | Hitoshi Yoshiji Ryuichi Noguchi Masaharu Yamazaki Yasuhide Ikenaka Masayoshi Sawai Masatoshi Ishikawa Hideto Kawaratani Tsuyoshi Mashitani Mitsuteru Kitade Kosuke Kaji Masahito Uemura Junichi Yamao Masao Fujimoto Akira Mitoro Masahisa Toyohara Motoyuki Yoshida Hiroshi Fukui | 2007 | World Journal of Gastroenterology2007，13，23： | 5 |

| 19 | MK-0626,a selective DPP-4 inhibitor,attenuates hepatic steatosis in ob/ob mice显示文摘AIM:To investigate the mechanism and in vivo effects of MK-0626,a dipeptidyl peptidase-4 inhibitor,on hepatic steatosis using ob/ob mice.METHODS:We analyzed obese(ob/ob)8-wk-old male mice that had been randomly divided into two groups of ob/ob mice(n=16 each)and were treated with1.5 or 3 mg/kg MK-0626 and two control groups of untreated ob/ob mice and lean littermates(n=16 each).All mice were fed a normal chow diet with or without MK-0626 for either four or eight weeks.Blood samples were collected,and total hepatectomy was performed.RESULTS:The administration of dietary MK-0626 ameliorated the hepatic lipid accumulation in ob/ob micetreated with 3 mg/kg MK-0626(3 MK),P<0.05,vs untreated ob/ob mice(ob/ob).The MK-0626 treatment reduced the serum alanine aminotransferase levels(both treatment groups,P<0.05 vs ob/ob)and glucoses/insulin levels/calculated HOMA scores(1.5 MK,P<0.05vs ob/ob;3 MK,P<0.01 vs ob/ob)and increased the serum adiponectin levels(3 MK,P<0.05 vs ob/ob)in a dose-dependent manner.The MK-0626 treatment increased the m RNA expression of peroxisome proliferator-activated receptorα/microsomal triglyceride transfer protein(1.5 MK,P<0.05 vs ob/ob;3 MK,P<0.01vs ob/ob)but reduced the sterol regulatory element binding transcription factor-1c/fatty acid synthase/stearoyl-Co A desaturase-1(both treatment groups,P<0.01 vs ob/ob).The MK-0626 treatment increased the activity of AMP-activated protein kinase(AMPK)(both treatment groups,P<0.01 vs ob/ob).CONCLUSION:MK-0626 could attenuate hepatic steatosis through enhancing AMPK activity,inhibiting hepatic lipogenic gene expression,enhancing triglyceride secretion from liver and increasing serum adiponectin levels. | Tatsuya Ohyama Ken Sato Yuichi Yamazaki Hiroaki Hashizume Norio Horiguchi Satoru Kakizaki Masatomo Mori Motoyasu Kusano Masanobu Yamada | 2014 | World Journal of Gastroenterology2014，20，43： | 4 |
| 20 | gastrointestinal symptom prevalence depends on disease duration and gastrointestinal region in type 2 diabetes mellitus显示文摘AIM To unravel relationships between gastrointestinal(GI)symptoms impairing quality of life(QOL)and clinical profiles of diabetes mellitus(DM)patients. METHODS We enrolled 134 outpatients with type 2 DM.Mean age was 64.7 years,mean body mass index was 24.7 RESULTS Lower abdominal symptoms were found to be more frequent than those affecting the upper abdomen.Diabetic duration and medications showed associations with GI symptoms.We identified differences in peak prevalences of the five symptoms.Gastralgia(P=0.02vs 10-14 years)and total GI symptoms(P=0.01 and P=0.02 vs 5-9 years and 10-14 years,respectively)peaked at a diabetes duration of 15-19 years.Heartburn(P=0.004)and postprandial fullness(P=0.03)tended to increase with disease duration.Constipation and diarrhea showed bimodal peaks,with the first early and the second late(e.g.,P=0.03 at 15-19 years vs 10-14years for diarrhea)in the disease course.Finally,GI symptoms showed clustering that reflected the region of the GI tract affected,i.e.,constipation and diarrhea had similar frequencies(P<0.0001). CONCLUSION Our study highlights the importance of questioning patients about QOL impairment due to abdominal symptoms,especially in the early and the late periods of diabetes. | Midori Fujishiro Akifumi Kushiyama Hiroki Yamazaki Sunao Kaneko Yuko Koketsu Takeshi Yamamotoya Takako Kikuchi Hideyuki Sakoda Ryo Suzuki Takashi Kadowaki | 2017 | World Journal of Gastroenterology2017，23，36： | 4 |
