| 1 | Evolving concepts in bone infection: redefining “biofilm”,“acute vs. chronic osteomyelitis”, “the immune proteome” and “local antibiotic therapy”显示文摘Osteomyelitis is a devastating disease caused by microbial infection of bone. While the frequency of infection following elective orthopedic surgery is low, rates of reinfection are disturbingly high. Staphylococcus aureus is responsible for the majority of chronic osteomyelitis cases and is often considered to be incurable due to bacterial persistence deep within bone. Unfortunately, there is no consensus on clinical classifications of osteomyelitis and the ensuing treatment algorithm. Given the high patient morbidity,mortality, and economic burden caused by osteomyelitis, it is important to elucidate mechanisms of bone infection to inform novel strategies for prevention and curative treatment. Recent discoveries in this field have identified three distinct reservoirs of bacterial biofilm including: Staphylococcal abscess communities in the local soft tissue and bone marrow, glycocalyx formation on implant hardware and necrotic tissue, and colonization of the osteocyte-lacuno canalicular network(OLCN) of cortical bone. In contrast, S.aureus intracellular persistence in bone cells has not been substantiated in vivo, which challenges this mode of chronic osteomyelitis. There have also been major advances in our understanding of the immune proteome against S. aureus, from clinical studies of serum antibodies and media enriched for newly synthesized antibodies(MENSA), which may provide new opportunities for osteomyelitis diagnosis, prognosis, and vaccine development. Finally, novel therapies such as antimicrobial implant coatings and antibiotic impregnated 3D-printed scaffolds represent promising strategies for preventing and managing this devastating disease. Here, we review these recent advances and highlight translational opportunities towards a cure. | Elysia A. Masters Ryan P.

| 2 | Concurrent systemic AA amyloidosis can discriminate primary sclerosing cholangitis from IgG4-associated cholangitis显示文摘Chronic hepatobiliary inflammatory diseases are not widely acknowledged as underlying disorders of systemic AA amyloidosis,except epidemic schistosomiasis.Among them,primary sclerosing cholangitis (PSC) might initiate amyloid A protein deposition in diverse tissues,giving rise to systemic amyloidosis,due to a progressive and unresolved inflammatory process,and its possible association with inflammatory bowel diseases.Nevertheless,only one such case has been reported in the literature to date.We report a 69-year-old Japanese woman with cirrhosis who was diagnosed with PSC complicated with systemic AA amyloidosis,without any evidence of other inflammatory disorders.As a result of cholestasis in conjunction with biliary strictures and increased serum IgG4,the presence of IgG4 + plasma cells was examined systemically,resulting in unexpected documentation of Congo-red-positive amyloid deposits,but not IgG4 + plasma cells,in the liver,stomach and salivary glands.Elevated serum IgG4 is the hallmark of IgG4-related disease,including IgG4-associated cholangitis,but it has also been demonstrated in certain patients with PSC.Amyloid A deposits in multiple organs associated with an indolent clinical course that progresses over many years might have a diagnostic value in discriminating PSC from IgG4-associated cholangitis. | Takehiro Kato Atsumasa Komori Sung-Kwan Bae Kiyoshi Migita Masahiro Ito Yasuhide Motoyoshi Seigo Abiru Hiromi Ishibashi | 2012 | World Journal of Gastroenterology2012，18，2： | 11 |
| 3 | Expression of pituitary tumor transforming gene in human gastric carcinoma显示文摘AIM:Pituitary tumor transforming gene (PTTG1) is overexpressed in a variety of tumors, including carcinomas of the lung, breast, colon, as well as in leukemia, lymphoma and pituitary adenomas.However,there is little information on its expression in gastric carcinoma. We sought to investigate the expression of PTTG1 in gastric carcinoma and to explore the relationship between its expression and clinicopathological factors.METHODS:We studied 75 primary human gastric adenocarcinomas, including 17 mucosal carcinomas, 21 submucosal infiltrative carcinomas, 12 carcinomas invading proprial muscle layers, 6 carcinomas reaching the subserosa,and 19 carcinomas penetrating the serosal surface.Immunohistochemical analysis was performed using paraffinembedded sections of gastric adenocarcinomas.RESULTS: PTTG1 was expressed heterogeneously in carcinomas. Positive PTTG1 staining was observed in 65.3% of the carcinomas (49 of 75). Its expression did not correlate significantly with either the histological type or the depth of infiltration of the gastric carcinomas.However,a statistical analysis showed significant differences between the primary adenocarcinomas and the associated metastatic lymph nodes.CONCLUSION: The results of this study demonstrate that PTTG1 expression is enhanced in metastatic lymph nodes in comparison to that in primary carcinomas. We suggest that PTTG1 may contribute to lymph node metastases in gastric carcinoma. | Chun-YangWen ToshiyukiNakayama MutsumiMatsuu KazukoShichijo IchiroSekine Ai-PingWang Masahiro Nakashima Yi-Tao Ding Masahiro Ito Hiromi Ishibashi | 2004 | World Journal of Gastroenterology2004，10，4： | 9 |
| 4 | Expression of β-catenin in hepatocellular carcinoma显示文摘AIM: The β-catenin has been recognized as a critical member of the Wnt signaling pathway and plays an important role in the generation/differentiation of many tissues. Inappropriate activation of this pathway has been implicated in carcinogenesis. The mechanism underlying the development as well as its prognosis of hepatocellular carcinoma (HCC) has remained unclear. The purpose of this study is to analyze the expression of β-catenin in HCC in relation to histological grades and viral hepatitis backgrounds.METHODS: Thirty-two sections were selected at random from autopsy and surgical cases of HCC. Immuohistologically,the location and positivity of β-catenin expression in HCC was examined.RESULTS: Normal hepatocytes did not express β-catenin.In 78% of HCC β-catenin was expressed at the membrane of the cells, with or without cytoplasmic and/or nuclear expression. The tumor cells with well- and moderatelydifferentiated grades expressed frequently at the membrane and cytoplasm compared with poorly-differentiated type.Nuclear expression of β-catenin was prone to occur in the tumor cells of poorly-differentiated grade. There were 15% of hepatitis C virus (HCV) backgrounds with nuclear expression. In contrast, there was 38% with nuclear expression in hepatitis B virus (HBV) backgrounds. In nonBnonC hepatitis, no case expressed nuclear β-catenin.CONCLUSION: The β-catenin expression in HCC cells was heterogenous among types of hepatitis viral infection.Wnt signaling pathway might be deeply involved in less-differentiated HCC and HBV background. | Liem Thanh Tien Masahiro Ito Mikiko Nakao Daisuke Niino Meirmanov Serik Masahiro Nakashima Chun-Yang Wen Hiroshi Yatsuhashi Hiromi Ishibashi | 2005 | World Journal of Gastroenterology2005，11，16： | 8 |
| 5 | A novel animal model for in vivo study of liver cancer metastasis显示文摘AIM:To establish an animal model with human hepatocyte-repopulated liver for the study of liver cancer metastasis.METHODS:Cell transplantation into mouse livers was conducted using alpha-fetoprotein(AFP)-producing hu-man gastric cancer cells(h-GCCs) and h-hepatocytes as donor cells in a transgenic mouse line expressing urokinase-type plasminogen activator(uPA) driven by the albumin enhancer/promoter crossed with a severe combined immunodeficient(SCID) mouse line(uPA/SCID mice).Host mice were divided into two groups(A and B).Group A mice were transplanted with h-GCCs alone,and group B mice were transplanted with h-GCCs and h-hepatocytes together.The replacement index(RI),which is the ratio of transplanted h-GCCs and h-hepatocytes that occupy the examined area of a histological section,was estimated by measuring h-AFP and h-albumin concentrations in sera,respectively,as well as by immunohistochemical analyses of h-AFP and human cytokeratin 18 in histological sections.RESULTS:The h-GCCs successfully engrafted,repopulated,and colonized the livers of mice in group A(RI = 22.0% ± 2.6%).These mice had moderately differentiated adenocarcinomatous lesions with disrupted glandular structures,which is a characteristics feature of gastric cancers.The serum h-AFP level reached 211.0 ± 142.2 g/mL(range,7.1-324.2 g/mL).In group B mice,the h-GCCs and h-hepatocytes independently engrafted,repopulated the host liver,and developed colonies(RI = 12.0% ± 6.8% and 66.0% ± 12.3%,respectively).h-GCC colonies also showed typical adenocarcinomatous glandular structures around the h-hepatocyte-colonies.These mice survived for the full 56 day-study and did not exhibit any metastasis of h-GCCs in the extrahepatic regions during the observational period.The mice with an h-hepatocyte-repopulated liver possessed metastasized h-GCCs and therefore could be a useful humanized liver animal model for studying liver cancer metastasis in vivo.CONCLUSION:A novel animal model of human liver cancer metastasis was established using the uPA/SCID mouse line.This model could be useful for in vivo testing of anti-cancer drugs and for studying the mechanisms of human liver cancer metastasis. | Shinsuke Fujiwara Hikaru Fujioka Chise Tateno Ken Taniguchi Masahiro Ito Hiroshi Ohishi Rie Utoh Hiromi Ishibashi Takashi Kanematsu Katsutoshi Yoshizato | 2012 | World Journal of Gastroenterology2012，18，29： | 6 |
| 6 | 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 |

| 12 | mPGES-1 expression in non-cancerous liver tissue impacts on postoperative recurrence of HCC显示文摘AIM:To investigate whether microsomal prostaglandin E synthase-1 (mPGES-1) expression in hepatocellular carcinoma (HCC) and in non-cancerous liver affects HCC prognosis after hepatectomy. METHODS: The relationship between patient clinical prof iles, tumor factors, surgical determinants, and mPGES-1 expression and the recurrence-free survival rate were examined in 64 patients who underwent curative hepatectomy between March 2003 and December 2006. RESULTS: The scores for mPGES-1 expression were higher in well differentiated and moderately differentiated HCC tissues than in poorly differentiated HCC tissues (well differentiated, 5.1 ± 2.7; moderately differentiated, 5.1 ± 1.7; poorly differentiated, 3.0 ± 1.8). In noncancerous liver tissues, the mPGES-1 levels were higher in injured liver tissues than in normal tissues. Cirrhotic livers had higher mPGES-1 levels than livers with chronic hepatitis (normal livers, 3.3 ± 0.7; chronic hepatitic livers, 5.4 ± 1.9; cirrhotic livers, 6.4 ± 1.6). A univariate analysis revealed that the recurrence-free survival rate was signif icantly lower in patients with vascular invasion,a higher mPGES-1 level in non-cancerous liver tissue,a larger tumor diameter (≥5 cm), and a lower serum albumin level (≤3.7 g/dL). The mPGES-1 expression in HCC tissues did not correlate well with postoperative recurrence. A multivariate analysis demonstrated that the presence of vascular invasion and higher mPGES-1 levels were statistically significant independent predictors for early postoperative recurrence of HCC.CONCLUSION: Increased mPGES-1 expression in noncancerous liver tissues is closely associated with the early recurrence of HCC after curative resection. | Koichi Nonaka Hikaru Fujioka Yasushi Takii Seigo Abiru Kiyoshi Migita Masahiro Ito Takashi Kanematsu Hiromi Ishibashi | 2010 | World Journal of Gastroenterology2010，16，38： | 2 |
| 13 | Novel serine/threonine kinase 11 gene mutations in PeutzJeghers syndrome patients and endoscopic management显示文摘AIM:To explore mutations in serine/threonine kinase 11(STK11) gene in Peutz-Jeghers syndrome(PJS) with gastrointestinal(GI) hamartomatous polyps.METHODS:Six Japanese PJS patients in 3 families were enrolled in this study.Each of the cases had hamartomatous polyposis in the gastrointestinal tract,including the small intestine,along with mucocutaneous hyperpigmentation.Narrow-band imaging(NBI)-magnification endoscopy was employed to detect microvascular and microsurface irregularities in the GI lesions.NBI magnification findings could be classified into three groups(type A,type B,or type C).Endoscopic polypectomy was performed using double-balloon enteroscopy or colonoscopy.Genomic DNA was extracted from a whole blood sample from each subject.All of the coding exons of STK11 gene,its boundary regions,and the promoter region containing the polymorphic regions were amplified by polymerase chain reaction,and direct sequencing was performed to assess the germline mutations.RESULTS:NBI-magnification endoscopic observation could detect the abnormalities in microvessels and microsurface structures of GI polyps.Overall,we found 5 cases of type A and one case without the examination for the gastric polyps,while there were 4 cases of type B and 2 case of type A for the colorectal polyps.Seventy-nine small-bowel and 115 colorectal polyps over 27 sessions for each were resected endoscopically without significant complications.The only delayed complication included the occurrence of bleeding in a case,and this was successfully managed with hemoclips.Resected polyps contained no malignant components.Based on mutation analysis,all 3 cases in Family I exhibited the +658C>T nonsense mutation in exon 5,which resulted in the production of a truncated protein(Q220X).In Family II,a case had-252C>A and-193C>A in the promoter region.In Family III,a case was found to have the +1062C>G(F342L) mutation in exon 8.CONCLUSION:We found two novel mutations of STK11 in association with PJS.Endoscopic polypectomy of GI polyps in PJS patients appears to be useful to prevent emergency laparotomies and reduce the cancer risk. | Hiroyuki Yajima Hajime Isomoto Hiroaki Nishioka Naoyuki Yamaguchi Ken Ohnita Tatsuki Ichikawa Fuminao Takeshima Saburo Shikuwa Masahiro Ito Kazuhiko Nakao Kazuhiro Tsukamoto Shigeru Kohno | 2013 | World Journal of Gastrointestinal Endoscopy2013，5，3： | 2 |
