| 1 | Preoperative, intraoperative and postoperative risk factors for anastomotic leakage after laparoscopic low anterior resection with double stapling technique anastomosis显示文摘Anastomotic leakage(AL) is one of the most devastating complications after rectal cancer surgery. The double stapling technique has greatly facilitated intestinal reconstruction especially for anastomosis after low anterior resection(LAR). Risk factor analyses for AL after open LAR have been widely reported. However, a few studies have analyzed the risk factors for AL after laparoscopic LAR. Laparoscopic rectal surgery provides an excellent operative field in a narrow pelvic space, and enables total mesorectal excision surgery and preservation of the autonomic nervous system with greater precision. However, rectal transection using a laparoscopic linear stapler is relatively difficult compared with open surgery because of the width and limited performance of the linear stapler. Moreover, laparoscopic LAR exhibits a different postoperative course compared with open LAR, which suggests that the risk factors for AL after laparoscopic LAR may also differ from those after open LAR. In this review, we will discuss the risk factors for AL after laparoscopic LAR. | Kenji Kawada Yoshiharu Sakai | 2016 | World Journal of Gastroenterology2016，22，25： | 53 |
| 2 | Role of hepatitis B virus DNA integration in human hepatocarcinogenesis显示文摘Liver cancer ranks sixth in cancer incidence,and is the third leading cause of cancer-related deaths worldwide.Hepatocellular carcinoma(HCC)is the most common type of liver cancer,which arises from hepatocytes and accounts for approximately 70%-85%of cases.Hepatitis B virus(HBV)frequently causes liver inflammation,hepatic damage and subsequent cirrhosis.Integrated viral DNA is found in 85%-90%of HBV-related HCCs.Its presence in tumors from non-cirrhotic livers of children or young adults further supports the role of viral DNA integration in hepatocarcinogenesis.Integration of subgenomic HBV DNA fragments into different locations within the host DNA is a significant feature of chronic HBV infection.Integration has two potential consequences:(1)the host genome becomes altered('cis'effect);and(2)the HBV genome becomes altered('trans'effect).The cis effect includes insertional mutagenesis,which can potentially disrupt host gene function or alter host gene regulation.Tumor progression is frequently associated with rearrangement and partial gain or loss of both viral and host sequences.However,the role of integrated HBV DNA in hepatocarcinogenesis remains controversial.Modern technology has provided a new paradigm to further our understanding ofdisease mechanisms.This review summarizes the role of HBV DNA integration in human carcinogenesis. | Hoang Hai Akihiro Tamori Norifumi Kawada | 2014 | World Journal of Gastroenterology2014，20，20： | 22 |
| 3 | Noninvasive assessment of liver fibrosis in patients with chronic hepatitis B显示文摘Infection with hepatitis B virus is an important healthproblem worldwide:it affects more than 350 millionpeople and is a leading cause of liver-related morbidity,accounting for 1 million deaths annually.Hepatic fibrosis is a consequence of the accumulation of extracellular matrix components in the liver.An accurate diagnosis of liver fibrosis is essential for the management of chronic liver disease.Liver biopsy has been considered the gold standard for diagnosing disease,grading necroinflammatory activity,and staging fibrosis.However,liver biopsy is unsuitable for repeated evaluations because it is invasive and can cause major complications,including death.Several noninvasive evaluations have been introduced for the assessment of liver fibrosis:serum biomarkers,combined indices or scores,and imaging techniques including transient elastography,acoustic radiation force impulse,real-time tissue elastography,and magnetic resonance elastography.Here,we review the recent progress of noninvasive assessment of liver fibrosis in patients with chronic hepatitis B.Most noninvasive evaluations for liver fibrosis have been validated first in patients with chronic hepatitis C,and later in those with chronic hepatitis B.The establishment of a noninvasive assessment of liver fibrosis is urgently needed to aid in the management of this leading cause of chronic liver disease. | Masaru Enomoto Hiroyasu Morikawa Akihiro Tamori Norifumi Kawada | 2014 | World Journal of Gastroenterology2014，20，34： | 16 |
| 4 | Insights from advances in research of chemically induced experimental models of human inflammatory bowel disease显示文摘Inflammatory bowel disease(IBD),the most important being Crohn's disease and ulcerative colitis,results from chronic dysregulation of the mucosal immune system in the gastrointestinal tract.Although the pathogenesis of IBD remains unclear,it is widely accepted that genetic,environmental,and immunological factors are involved.Recent studies suggest that intestinal epithelial defenses are important to prevent inflammation by protecting against microbial pathogens and oxidative stresses.To investigate the etiology of IBD,animal models of experimental colitis have been developed and are frequently used to evaluate new anti-inflammatory treatments for IBD.Several models of experimental colitis that demonstrate various pathophysiological aspects of the human disease have been described.In this manuscript,we review the characteristic features of IBD through a discussion of the various chemically induced experimental models of colitis(e.g.dextran sodium sulfate-,2,4,6-trinitrobenzene sulfonic acid-,oxazolone-,acetic acid-,and indomethacin-induced models).We also summarize some regulatory and pathogenic factors demonstrated by these models that can,hopefully,be exploited to develop future therapeutic strategies against IBD. | Mayumi Kawada Atsuko Arihiro Emiko Mizoguchi | 2007 | World Journal of Gastroenterology2007，13，42： | 12 |
| 5 | Nutritional status in relation to lifestyle in patients with compensated viral cirrhosis显示文摘AIM:To assess the nourishment status and lifestyle of non-hospitalized patients with compensated cirrhosis by using noninvasive methods.METHODS:The subjects for this study consisted of 27 healthy volunteers,59 patients with chronic viral hepatitis,and 74 patients with viral cirrhosis,from urban areas.We assessed the biochemical blood tests,anthropometric parameters,diet,lifestyle and physical activity of the patients.A homeostasis model assessment-insulin resistance(HOMA-IR) value of ≥ 2.5 was considered to indicate insulin resistance.We measured height,weight,waist circumference,arm circumference,triceps skin-fold thickness,and handgrip strength,and calculated body mass index,arm muscle circumference(AMC),and arm muscle area(AMA).We interviewed the subjects about their dietary habits and lifestyle using health assessment computer software.We surveyed daily physical activity using a pedometer.Univariate and multivariate logistic regression modeling were used to identify the relevant factors for insulin resistance.RESULTS:The rate of patients with HOMA-IR ≥ 2.5(which was considered to indicate insulin resistance) was 14(35.9%) in the chronic hepatitis and 17(37.8%) in the cirrhotic patients.AMC(%)(control vs chronic hepatitis,111.9% ± 10.5% vs 104.9% ± 10.7%,P = 0.021;control vs cirrhosis,111.9% ± 10.5% vs 102.7% ± 10.8%,P = 0.001) and AMA(%)(control vs chronic hepatitis,128.2% ± 25.1% vs 112.2% ± 22.9%,P = 0.013;control vs cirrhosis,128.2% ± 25.1% vs 107.5% ± 22.5%,P = 0.001) in patients with chronic hepatitis and liver cirrhosis were significantly lower than in the control subjects.Handgrip strength(%) in the cirrhosis group was significantly lower than in the controls(control vs cirrhosis,92.1% ± 16.2% vs 66.9% ± 17.6%,P < 0.001).The results might reflect a decrease in muscle mass.The total nutrition intake and amounts of carbohydrates,protein and fat were not significantly different amongst the groups.Physical activity levels(kcal/d)(control vs cirrhosis,210 ± 113 kcal/d vs 125 ± 74 kcal/d,P = 0.001),number of steps(step/d)(control vs cirrhosis,8070 ±3027 step/d vs 5789 ± 3368 step/d,P = 0.011),and exercise(Ex)(Ex/wk)(control vs cirrhosis,12.4 ± 9.3 Ex/wk vs 7.0 ± 7.7 Ex/wk,P = 0.013) in the cirrhosis group was significantly lower than the control group.The results indicate that the physical activity level of the chronic hepatitis and cirrhosis groups were low.Univariate and multivariate logistic regression modeling suggested that Ex was associated with insulin resistance(odds ratio,6.809;95% CI,1.288-36.001;P = 0.024).The results seem to point towards decreased physical activity being a relevant factor for insulin resistance.CONCLUSION:Non-hospitalized cirrhotic patients may need to maintain an adequate dietary intake and receive lifestyle guidance to increase their physical activity levels. | Fumikazu Hayashi Chika Momoki Miho Yuikawa Yuko Simotani Etsushi Kawamura Atsushi Hagihara Hideki Fujii Sawako Kobayashi Shuji Iwai Hiroyasu Morikawa Masaru Enomoto Akihiro Tamori Norifumi Kawada Satoko Ohfuji Wakaba Fukusima Daiki Habu | 2012 | World Journal of Gastroenterology2012，18，40： | 11 |
| 6 | Hepatitis B virus infection and alcohol consumption显示文摘Hepatocellular carcinoma(HCC) is the most common type of primary liver cancer, and the second most common cause of cancer deaths worldwide. The top three causes of HCC are hepatitis B virus(HBV),hepatitis C virus(HCV), and alcoholic liver disease. Owing to recent advances in direct-acting antiviral agents, HCV can now be eradicated in almost all patients. HBV infection and alcoholic liver disease are expected, therefore, to become the leading causes of HCC in the future. However, the association between alcohol consumption and chronic hepatitis B in the progression of liver disease is less well understood than with chronic hepatitis C. The mechanisms underlying the complex interaction between HBV and alcohol are not fully understood, and enhanced viral replication, increased oxidative stress and a weakened immune response could each play an important role in the development of HCC. It remains controversial whether HBV and alcohol synergistically increase the incidence of HCC. Herein, we review the currently available literature regarding the interaction of HBV infection and alcohol consumption on disease progression. | ayako iida-ueno masaru enomoto akihiro tamori norifumi kawada | 2017 | World Journal of Gastroenterology2017，23，15： | 11 |
| 7 | Elastography for the pancreas: Current status and future perspective显示文摘Elastography for the pancreas can be performed by either ultrasound or endoscopic ultrasound(EUS). There are two types of pancreatic elastographies based on different principles, which are strain elastography and shear wave elastography. The stiffness of tissue is estimated by measuring the grade of strain generated by external pressure in the former, whereas it is estimated by measuring propagation speed of shear wave, the transverse wave, generated by acoustic radiation impulse(ARFI) in the latter. Strain elastography is difficult to perform when the probe, the pancreas and the aorta are not located in line. Accordingly, a fine elastogram can be easily obtained in the pancreatic body but not in the pancreatic head and tail. In contrast, shear wave elastography can be easily performed in the entire pancreas because ARFI can be emitted to wherever desired. However, shear wave elastography cannot be performed by EUS to date. Recently, clinical guidelines for elastography specialized in the pancreas were published from Japanese Society of Medical Ultrasonics. The guidelines show us technical knacks of performing elastography for the pancreas. | Natsuko Kawada Sachiko Tanaka | 2016 | World Journal of Gastroenterology2016，22，14： | 8 |
| 8 | Gene expression profiles of hepatic cell-type specific marker genes in progression of liver fibrosis显示文摘AIM: To determine the gene expression profile data for the whole liver during development of dimethylni-trosamine (DMN)-induced hepatic fibrosis.METHODS: Marker genes were identified for different types of hepatic cells, including hepatic stellate cells (HSCs), Kupffer cells (including other inflammatory cells), and hepatocytes, using independent temporal DNA microarray data obtained from isolated hepatic cells. RESULTS: The cell-type analysis of gene expression gave several key results and led to formation of three hypotheses: (1) changes in the expression of HSC-specific marker genes during fibrosis were similar to gene expression data in in vitro cultured HSCs, suggesting a major role of the self-activating characteristics of HSCs in formation of fibrosis; (2) expression of mast cell-specific marker genes reached a peak during liver fibrosis, suggesting a possible role of mast cells in formation of fibrosis; and (3) abnormal expression of hepatocyte-specific marker genes was found across several metabolic pathways during fibrosis, including sulfur-containing amino acid metabolism, fatty acid metabolism, and drug metabolism, suggesting a mechanistic relationship between these abnormalities and symptoms of liver fibrosis. CONCLUSION: Analysis of marker genes for specific hepatic cell types can identify the key aspects of fibro-genesis. Sequential activation of inflammatory cells and the self-supporting properties of HSCs play an important role in development of fibrosis. | Yoshiyuki Takahara Mitsuo Takahashi Hiroki Wagatsuma Fumihiko Yokoya Qing-Wei Zhang Mutsuyo Yamaguchi Hiroyuki Aburatani Norifumi Kawada | 2006 | World Journal of Gastroenterology2006，12，40： | 5 |
| 9 | HLA class Ⅱ associated with outcomes of hepatitis B and C infections显示文摘Several factors influence the clinical course of hepatitis B virus(HBV)and hepatitis C virus(HCV)infection.The human leukocyte antigen(HLA)system,the major histocompatibility complex(MHC)in humans,has been considered one of the most important host factors with respect to outcomes.To date,conventional genotyping studies have shown that HLA classⅡloci are mainly associated with spontaneous clearance of HBV and HCV.However,the specific HLA locus associated with the outcomes of hepatitis virus infection remains unclear.A recent genome-wide association study(GWAS)using a comprehensive approach for human genotyping demonstrated single nucleotide polymorphisms(SNPs)associated with the outcomes of hepatitis virus infection.Examination of large numbers of cohorts revealed that several SNPs in both HLA-DPA1 and HLADPB1 loci are associated with persistent HBV infection in Asian populations.To date,however,few studies have focused on HLA-DP because polymorphisms of HLA-DP haplotype do not vary greatly as compared with other loci of HLA.There are not enough studies to reveal the function of HLA-DP.GWAS additionally detected candidate SNPs within HLA loci associated with chronic HBV or HCV hepatitis,hepatic fibrosis,and the development of hepatocellular carcinoma.The results of one cohort were not always consistent with those of other cohorts.To solve several controversial issues,it is necessary to validate reported SNPs on HLA loci in global populations and to elucidate the HLA-allele-regulated molecular response to hepatitis virus infection. | Akihiro Tamori Norifumi Kawada | 2013 | World Journal of Gastroenterology2013，19，33： | 4 |

| 11 | Fibrogenesis in alcoholic liver disease显示文摘Alcoholic liver disease(ALD) is a major cause of morbidity and mortality worldwide. In developed countries,ALD is a major cause of end-stage liver disease that requires transplantation. The spectrum of ALD includes simple steatosis, alcoholic hepatitis, fibrosis, cirrhosis,and hepatocellular carcinoma. Alcohol abstinence is the most effective therapy for ALD. However, targeted therapies are urgently needed for patients with severe ALD(i.e., alcoholic hepatitis) or those who do not abstain from alcohol. The lack of studies and the availability of animal models that do not reflect all the features of this disease in humans inhibit the development of new drugs for ALD. In ALD-associated fibrosis, hepatic stellate cells are the principal cell type responsible for extracellular matrix production. Although the mechanisms underlying fibrosis in ALD are largely similar to those observed in other chronic liver diseases, oxidative stress, methionine metabolism abnormalities, hepatocyte apoptosis, and endotoxin lipopolysaccharides that activate Kupffer cells may play unique roles in diseaserelated fibrogenesis. Lipogenesis during the early stag-es of ALD has recently been implicated as a risk factor for the progression of cirrhosis. Other topics include osteopontin, interleukin-1 signaling, and genetic polymorphism. In this review, we discuss the basic pathogenesis of ALD and focus on liver fibrogenesis. | Hideki Fujii Norifumi Kawada | 2014 | World Journal of Gastroenterology2014，20，25： | 4 |
| 12 | Bowel preparation for colonoscopy using standard vs reduced doses of sodium phosphate: A single-blind randomized controlled study显示文摘AIM: To evaluate the efficacy of a colonoscopy prepa-ration that utilizes a reduced dose of sodium phosphate(NaP) and an adjunct.METHODS: Sixty-two patients requiring screening colonoscopies were studied. Each patient was randomly allocated to receive either 50 NaP tablets(50 g) or 30 NaP tablets(30 g) with 10 mL of 0.75% sodium pico-sulfate for bowel preparation. NaP was administered at a rate of five tablets(5 g) or three tablets(3 g) every 15 min with 200 mL of water, beginning five to six hours before colonoscopy. The sodium picosulfate was administered with 200 mL of water on the night before the procedure. Both groups were compared in term of the efficacies of colonic cleansing, the time required for completion of the bowel preparation, and acceptability of the preparation.RESULTS: Sixty patients(n = 30 for each group) were analyzed. The cleansing efficacy tended to be higher in the 30 g NaP plus sodium picosulfate group as as-sessed by the mean total Ottawa scale score(50 g NaP6.70 ± 1. 42 vs 30 g NaP plus sodium picosulfate 6.17 ± 1.18 P = 0.072). The mean time for bowel prepara-tion tended to be shorter in the 30 g NaP plus sodium picosulfate group(50 g NaP 189.9 ± 64.0 min vs 30 g NaP plus sodium picosulfate 161.8 ± 57.6 min, P = 0.065). There were no significant differences between the two groups in the acceptability of the preparations(50 g NaP 83.3% vs 30 g NaP plus sodium picosulfate 86.7%, P = 0.500). There were no adverse events re-lated to bowel preparation in either of the groups.CONCLUSION: The colonoscopy preparation that uti-lized 30 g NaP with sodium picosulfate was comparable to that utilizing 50 g NaP. This novel bowel preparation might be useful before colonoscopy. | Tatsuya Koshitani Mayumi Kawada Toshikazu Yoshikawa | 2014 | World Journal of Gastrointestinal Endoscopy2014，6，8： | 3 |
