| 1 | Laparoscopic hemicolectomy in a patient with situs inversustotalis显示文摘As among persons with normal anatomy, occasional patients with situs inversus develop malignant tumors. Recently, several laparoscopic operations have been reported in patients with situs inversus. We describe laparoscopic hemicolectomy with radical lymphadenectomy in such a patient. Careful consideration of the mirror-image anatomy permitted safe operation using techniques not otherwise differing from those in ordinary cases. Thus, curative laparoscopic surgery for colon cancer in the presence of situs inversus is feasible and safe. | Yushi Fujiwara Yosuke Fukunaga Masayuki Higashino Shinya Tanimura Masashi Takemura Yoshinori Tanaka Harushi Osugi | 2007 | World Journal of Gastroenterology2007，13，37： | 6 |
| 2 | Classifying genotype F of hepatitis B virus into F1 and F2 subtypes显示文摘AIM: To explore the propriety of providing hepatitis B virus(HBV) genotypes F and H with two distinct genotypes.METHODS: Eleven HBV isolates of genotype F (HBV/F)were recovered from patients living in San Francisco,Japan, Panama, and Venezuela, and their full-length sequences were determined. Phylogenetic analysis was carried out among them along with HBV isolates previously reported.RESULTS: Seven of them clustered with reported HBV/F isolates in the phylogenetic tree constructed on the entire genomic sequence. The remaining four flocked on another branch along with three HBV isolates formerly reported as genotype H. These seven HBV isolates, including the four in this study and the three reported, had a sequence divergence of 7.3-9.5% from the other HBV/F isolates,and differed by > 13.7% from HBV isolates of the other six genotypes (A-E and G). Based on a marked genomic divergence, falling just short of >8% separating the seven genotypes, these seven HBV/F isolates were classified into F2 subtype and the former seven into F1 subtype provisionally. In a pairwise comparison of the S-gene sequences among the 7 HBV/F2 isolates and against 47HBV/F1 isolates as well as 136 representing the other six genotypes (A-E and G), two clusters separated by distinct genetic distances emerged.CONCLUSION: Based on these analyses, classifying HBV/F isolates into two subtypes (F1 and F2) would be more appropriate than providing them with two distinct genotypes (F and H). | Hideaki Kato Kei Fujiwara Robert G.

| 3 | Distribution of HBV genotypes among HBV carriers in Benin:phylogenetic analysis and virological characteristics of HBV genotype E显示文摘AIM: To determine the distribution of Hepatitis B virus (HBV) genotypes in Benin, and to clarify the virological characteristics of the dominant genotype.METHODS: Among 500 blood donors in Benin, 21 HBsAg-positive donors were enrolled in the study. HBV genotypes were determined by enzyme immunoassay and restriction fragment length polymorphism. Complete genome sequences were determined by PCR and direct sequencing.RESULTS: HBV genotype E (HBV/E) was detected in 20/21 (95.2%), and HBV/A in 1/21 (4.8%). From the age-specific prevalence of HBeAg to anti-HBe seroconversion (SC) in 19 HBV/E subjects, SC was estimated to occur frequently in late teens in HBV/E.The comparison of four complete HBV/E genomes from HBeAg-positive subjects in this study and five HBV/E sequences recruited from the database revealed that HBV/E was distributed throughout West Africa with very low genetic divers ity (nucleotide homology 96.7-99.2%).Based on the sequences in the basic core promoter (BCP)to precore region of the nine HBV/E isolates compared to those of the other genotypes, a nucleotide substitution in the BCP, G1757A, was observed in HBV/E.CONCLUSION: HBV/E is predominant in the Republic of Benin, and SC is estimated to occur in late teens in HBV/E. The specific nucleotide substitution G1757A in BCP, which might influence the virological characteristics,is observed in HBV/E. | Kei Fujiwara Yasuhito Tanaka Etsuro Orito Tomoyoshi Ohno Takanobu Kato Kanji Sugihara Izumi Hasegawa Mayumi Sakurai Kiyoaki Ito Atsushi Ozasa Yuko Sakamoto Isao Arita Ahmed El-Gohary Agossou Benoit Sophie I Ogoundele-Akplogan Namiko Yoshihara Ryuzo Ueda Masashi Mizokami | 2005 | World Journal of Gastroenterology2005，11，41： | 3 |
| 4 | New combination test for hepatitis C virus genotype and viral load determination using Amplicor GT HCV MONITOR test v2.0显示文摘AIM: To develop a new sensitive and inexpensive hepatitis C virus (HCV) combination test (HCV Guideline test) that enables the determination of HCV genotypes 1, 2 and 3,and simultaneous determination of HCV viral load using commercial Amplicor GT HCV MONITOR test v2.0 (microwell version).METHODS: The HCV Guideline test used the PCR product generated in commercial Amplicor GT HCV Monitor test v2.0 for viral load measurement using microwell plate version of Amplicor HCV Monitor and also captured on separate plates containing capture probes and competitive oligonucleotide probes specific for HCV genotypes 1, 2 and 3, The HCV genotype was subsequently determined using the biotin-labeled PCR product and five biotin-labeled HCV-specific probes.RESULTS: The sensitivity of the HCV Guideline test was 0.5 KIU/mL. Specificity of the HCV Guideline test was confirmed by direct sequencing of HCV core region and molecular evolutionary analyses based on a panel of 31 samples. The comparison of the HCV Guideline test and an in-house HCV core genotyping assay using 252 samples from chronic hepatitis C patients indicated concordant results for 97.2% of samples (59.5% genotype 1, 33.7% genotype 2, 6.0% genotype 3, and 0.8% mixed genotypes).Similarly, the HCV Guideline test showed concordance with a serological test, and the serological test failed to assign any serotype in 12.7% of the samples, indicating a better sensitivity of the HCV Guideline test.CONCLUSION: Clinically, both viral load and genotypes (1, 2 and 3) have been found to be major predictors of antiviral therapy outcome regarding chronic hepatitis C based on guidelines and they are, in normal circumstances,performed as separate stand-alone assays. The HCV Guideline test is a useful method for screening large cohorts in a routine clinical setting for determining the treatment regimen and for predicting the outcome of antiviral therapy of chronic hepatitis C. | Motokazu Mukaide Yasuhito Tanaka Hirokazu Kakuda Kei Fujiwara Fuat Kurbanov Eturo Orito Kentaro Yoshioka Kiyotaka Fujise Shoji Harada Takazumi Kozaki Kazuo Takemura Kazumasa Hikiji Masashi Mizokami | 2005 | World Journal of Gastroenterology2005，11，4： | 3 |
| 5 | CD14 upregulation as a distinct feature of non-alcoholic fatty liver disease after pancreatoduodenectomy显示文摘AIM:To investigate the pathogenesis of non-alcoholic fatty liver disease(NAFLD)after pancreatoduodenectomy(PD).METHODS:A cohort of 82 patients who underwent PD at Okayama University Hospital between 2003 and 2009 was enrolled and the clinicopathological features were compared between patients with and without NAFLD after PD.Computed tomography(CT)images were evaluated every 6 mo after PD for follow-up.Hepatic steatosis was diagnosed on CT when hepatic attenuation values were 40 Hounsfield units.Liver biopsy was performed for 4 of 30 patients with NAFLD after PD who consented to undergo biopsies.To compare NAFLD after PD with NAFLD associated with metabolic syndrome,liver samples were obtained from 10 patients with NAFLD associated with metabolic syndrome [fatty liver,n = 5;non-alcoholic steatohepatitis(NASH),n = 5] by percutaneous ultrasonography-guided liver biopsy.Double-fluorescence immunohistochemistry was applied to examine CD14 expression as a marker of lipopolysaccharide(LPS)-sensitized macrophage cells(Kupffer cells)in liver biopsy specimens.RESULTS:The incidence of postoperative NAFLD was 36.6%(30/82).Univariate analysis identified cancer of the pancreatic head,sex,diameter of the main pancreatic duct,and dissection of the nerve plexus as factors associated with the development of NAFLD after PD.Those patients who developed NAFLD after PD demonstrated significantly decreased levels of serum albumin,total protein,cholesterol and triglycerides compared to patients without NAFLD after PD,but no glucose intolerance or insulin resistance.Liver biopsy was performed in four patients with NAFLD after PD.All four patients showed moderate-to-severe steatosis and NASH was diagnosed in two.Numbers of cells positive for CD68(a marker of Kupffer cells)and CD14(a marker of LPSsensitized Kupffer cells)were counted in all biopsy specimens.The number of CD68+ cells in specimens of NAFLD after PD was significantly increased from that in specimens of NAFLD associated with metabolic syndrome specimens,which indicated the presence of significantly more Kupffer cells in NAFLD after PD than in NAFLD associated with metabolic syndrome.Similarly,more CD14+ cells,namely,LPS-sensitized Kupffer cells,were observed in NAFLD after PD than in NAFLD associated with metabolic syndrome.Regarding NASH,more CD68+ cells and CD14+ cells were observed in NASH after PD specimens than in NASH associated with metabolic syndrome.This showed that more Kupffer cells and more LPS-sensitized Kupffer cells were present in NASH after PD than in NASH associated with metabolic syndrome.These observations suggest that after PD,Kupffer cells and LPS-sensitized Kupffer cells were significantly upregulated,not only in NASH,but also in simple fatty liver.CONCLUSION:NAFLD after PD is characterized by both malnutrition and the up-regulation of CD14 on Kupffer cells.Gut-derived endotoxin appears central to the development of NAFLD after PD. | Daisuke Satoh Takahito Yagi Takeshi Nagasaka Susumu Shinoura Yuzo Umeda Ryuichi Yoshida Masashi Utsumi Takehiro Tanaka Hiroshi Sadamori Toshiyoshi Fujiwara | 2013 | World Journal of Hepatology2013，5，4： | 3 |
| 6 | Genotype and phylogenetic characterization of hepatitis B virus among multi-ethnic cohort in Hawaii显示文摘AIM: Hepatitis B virus (HBV) genomes in carriers from Hawaii have not been evaluated previously. The aim of thepresent study was to evaluate the distribution of HBV genotypes and their clinical relevance in Hawaii.METHODS: Genotyping of HBV among 61 multi-ethnicc arriers in Hawaii was performed by genetic methods.Three complete genomes and 61 core promoter/precore regions of HBV were sequenced directly.RESULTS: HBV genotype distribution among the 61 carderswas 23.0% for genotype A, 14.7% for genotype B and 62.3% for genotype C. Genotypes A, B and C were obtained from the carriers whose ethnicities were Filipino and Caucasian,Southeast Asian, and various Asian and Micronesian,respectively. All cases of genotype B were composed of recombinant strains with genotype C in the precore plus core region named genotype Ba. HBeAg was detected more frequently in genotype C than in genotype B (68.4% vs 33.3%, P<0.05) and basal core promoter (BCP) mutation (T1762/A1764) was more frequently found in genotype C than in genotype B. Twelve of the 38 genotype C strains possessed C at nucleotide (nt) position 1858 (C-1858).However there was no significant difference in clinical characteristics between C-1858 and T-1858 variants. Based on complete genome sequences, phylogenetic analysis revealed one patient of Micronesian ethnicity as having C1858 clustered with two isolates from Polynesia with T-1858.In addition, two strains from Asian ethnidties were clustered with known isolates in carriers from Southeast Asia.CONCLUSION: Genotypes A, B and C are predominant types among multi-ethnic HBV carriers in Hawaii, and distribution of HBV genotypes is dependent on the ethnic background of the carriers in Hawaii. | Mayumi Sakurai Fuminaka Sugauchi Naoky Tsai Seiji Suzuki Izumi Hasegawa Kei Fujiwara Etsuro Orito Ryuzo Ueda Masashi Mizokami | 2004 | World Journal of Gastroenterology2004，10，15： | 2 |
