| 1 | Efficacy and safety of over-the-scope clip: Including complications after endoscopic submucosal dissection显示文摘AIM: To retrospectively review the results of over-thescope clip (OTSC) use in our hospital and to examine the feasibility of using the OTSC to treat perforations after endoscopic submucosal dissection (ESD). METHODS: We enrolled 23 patients who presented with gastrointestinal (GI) bleeding, fistulae and perforations and were treated with OTSCs (Ovesco Endoscopy GmbH, Tuebingen, Germany) between November 2011 and September 2012. Maximum lesion size was defined as lesion diameter. The number of OTSCs to be used per patient was not decided until the lesion was completely closed. We used a twin grasper (Ovesco Endoscopy GmbH, Tuebingen, Germany) as a grasping device for all the patients. A 9 mm OTSC was chosen for use in the esophagus and colon, and a 10 mm device was used for the stomach, duodenum and rectum. The overall success rate and complications were evaluated, with a particular emphasis on patients who had undergone ESD due to adenocarcinoma. In technical successful cases we included not only complete closing by using OTSCs, but also partial closing where complete closure with OTSCs is almost difficult. In overall clinical successful cases we included only complete closing by using only OTSCs perfectly. All the OTSCs were placed by 2 experienced endoscopists. The sites closed after ESD included not only the perforation site but also all defective ulcers sites.RESULTS: A total of 23 patients [mean age 77 years (range 64-98 years)] underwent OTSC placement during the study period. The indications for OTSC placement were GI bleeding (n = 9), perforation (n = 10), fistula (n = 4) and the prevention of post-ESD duodenal artificial ulcer perforation (n = 1). One patient had a perforation caused by a glycerin enema, after which a fistula formed. Lesion closure using the OTSC alone was successful in 19 out of 23 patients, and overall success rate was 82.6%. A large lesion size (greater than 20 mm) and a delayed diagnosis (more than 1 wk) were the major contributing factors for the overall unsuccessful clinical cases. The location of the unsuccessful lesion was in the stomach. The median operation time in the successful cases was 18 min, and the average observation time was 67 d. During the observation period, none of the patients experienced any complications associated with OTSC placement. In addition, we successfully used the OTSC to close the perforation site after ESD in 6 patients. This was a single-center, retrospective study with a small sample size. CONCLUSION: The OTSC is effective for treating GI bleeding, fistulae as well as perforations, and the OTSC technique proofed effective treatment for perforation after ESD. | Noriko Nishiyama Hirohito Mori Hideki Kobara Kazi Rafiq Shintarou Fujihara Mitsuyoshi Kobayashi Makoto Oryu Tsutomu Masaki | 2013 | World Journal of Gastroenterology2013，19，18： | 42 |
| 2 | Diagnosis and Treatment of Keloids and Hypertrophic Scars—Japan Scar Workshop Consensus Document 2018显示文摘There has been a long-standing need for guidelines on the diagnosis and treatment of keloids and hypertrophic scars that are based on an understanding of the pathomechanisms that underlie these skin fibrotic diseases.This is particularly true for clinicians who deal with Asian and African patients because these ethnicities are highly prone to these diseases.By contrast,Caucasians are less likely to develop keloids and hypertrophic scars,and if they do,the scars tend not to be severe.This ethnic disparity also means that countries vary in terms of their differential diagnostic algorithms.The lack of clear treatment guidelines also means that primary care physicians are currently applying a hotchpotch of treatments,with uneven outcomes.To overcome these issues,the Japan Scar Workshop(JSW)has created a tool that allows clinicians to objectively diagnose and distinguish between keloids,hypertrophic scars,and mature scars.This tool is called the JSW Scar Scale(JSS)and it involves scoring the risk factors of the individual patients and the affected areas.The tool is simple and easy to use.As a result,even physicians who are not accustomed to keloids and hypertrophic scars can easily diagnose them and judge their severity.The JSW has also established a committee that,in cooperation with outside experts in various fields,has prepared a Consensus Document on keloid and hypertrophic scar treatment guidelines.These guidelines are simple and will allow even inexperienced clinicians to choose the most appropriate treatment strategy.The Consensus Document is provided in this article.It describes(1)the diagnostic algorithm for pathological scars and how to differentiate them from clinically similar benign and malignant tumors,(2)the general treatment algorithms for keloids and hypertrophic scars at different medical facilities,(3)the rationale behind each treatment for keloids and hypertrophic scars,and(4)the body site-specific treatment protocols for these scars.We believe that this Consensus Document will be helpful for physicians from all over the world who treat keloids and hypertrophic scars. | Rei Ogawa Sadanori Akita Satoshi Akaishi Noriko Aramaki-Hattori Teruyuki Dohi Toshihiko Hayashi Kazuo Kishi Taro Kono Hajime Matsumura Gan Muneuchi Naoki Murao Munetomo Nagao Keisuke Okabe Fumiaki Shimizu Mamiko Tosa Yasuyoshi Tosa Satoko Yamawaki Shinichi Ansai Norihisa Inazu Toshiko Kamo Reiko Kazki Shigehiko Kuribayashi | 2019 | Burns & Trauma2019，7，1： | 31 |

| 5 | Helicobacter pylori-related chronic gastritis as a risk factor for colonic neoplasms显示文摘To summarize the current views and insights on associations between Helicobacter pylori(H. pylori)-related chronic gastritis and colorectal neoplasm, we reviewed recent studies to clarify whether H. pylori infection/H. pylori-related chronic gastritis is associated with an elevated risk of colorectal neoplasm. Recent studies based on large databases with careful control for confounding variables have clearly demonstrated an increased risk of colorectal neoplasm associated with H. pylori infection. The correlation between H. pylori-related chronic atrophic gastritis(CAG) and colorectal neoplasm has only been examined in a limited number of studies. A recent large study using a national histopathological database, and our study based on the stage of H. pylori-related chronic gastritis as determined by serum levels of H. pylori antibody titer and pepsinogen, indicatedthat H. pylori-related CAG confers an increased risk of colorectal neoplasm, and more extensive atrophic gastritis will probably be associated with even higher risk of neoplasm. In addition, our study suggested that the activity of H. pylori-related chronic gastritis is correlated with colorectal neoplasm risk. H. pylori-related chronic gastritis could be involved in an increased risk of colorectal neoplasm that appears to be enhanced by the progression of gastric atrophy and the presence of active inflammation. | Izumi Inoue Jun Kato Hideyuki Tamai Mikitaka Iguchi Takao Maekita Noriko Yoshimura Masao Ichinose | 2014 | World Journal of Gastroenterology2014，20，6： | 25 |

| 9 | Long-term outcome of percutaneous ethanol injection therapy for minimum-sized hepatocellular carcinoma显示文摘AIM: To evaluate long-term follow-up of minimum-sized hepatocellular carcinoma (HCC) treated with percutaneous ethanol injection (PEI). METHODS: PEI was applied to 42 lesions in 31 patients (23 male and eight female) with HCC < 15 mm in diameter, over the past 15 years. RESULTS: Overall survival rate was 74.1% at 3 years, 49.9% at 5 years, 27.2% at 7 years and 14.5% at 10 years. These results are superior to, or at least the same as those for hepatic resection and radiofrequency ablation. Survival was affected only by liver function, but not by sex, age, etiology of Hepatitis B virus or Hepatitis C virus, α-fetoprotein levels, arterial and portal blood flow, histological characteristics, and tumor multiplicity or size. Patients in Child-Pugh class A and B had 5-, 7- and 10-years survival rates of 76.0%, 42.2% and 15.8%, and 17.1%, 8.6% and 0%, respectively (P = 0.025). CONCLUSION: Treatment with PEI is best indicated for patients with HCC < 15 mm in Child-Pugh class A. | Miyuki Taniguchi Soo Ryang Kim Susumu Imoto Hirotsugu Ikawa Kenji Ando Keiji Mita Shuichi Fuki Noriko Sasase Toshiyuki Matsuoka Masatoshi Kudo Yoshitake Hayashi | 2008 | World Journal of Gastroenterology2008，14，13： | 16 |
| 10 | Imaging of community-acquired pneumonia: Roles of imaging examinations, imaging diagnosis of specific pathogens and discrimination from noninfectious diseases显示文摘This article reviews roles of imaging examinations in the management of community-acquired pneumonia(CAP), imaging diagnosis of specific CAP and discrimination between CAP and noninfectious diseases. Chest radiography is usually enough to confirm the diagnosis of CAP, whereas computed tomography is required to suggest specific pathogens and to discriminate from noninfectious diseases. Mycoplasma pneumoniae pneumonia, tuberculosis, Pneumocystis jirovecii pneumonia and some cases of viral pneumonia sometimes show specific imaging findings. Peribronchial nodules, especially tree-in-bud appearance, are fairly specific for infection. Evidences of organization, such as concavity of the opacities, traction bronchiectasis, visualization of air bronchograms over the entire length of the bronchi, or mild parenchymal distortion are suggestive of organizing pneumonia. We will introduce tips to effectively make use of imaging examinations in the management of CAP. | Atsushi Nambu Katsura Ozawa Noriko Kobayashi Masao Tago | 2014 | World Journal of Radiology2014，6，10： | 15 |
| 11 | Feasibility of cold snare polypectomy in Japan: A pilot study显示文摘AIM: To investigate the feasibility of cold snare polypectomy(CSP) in Japan.METHODS: The outcomes of 234 non-pedunculated polyps smaller than 10 mm in 61 patients who underwent CSP in a Japanese referral center were retrospectively analyzed. The cold snare polypectomies were performed by nine endoscopists with no prior experience in CSP using an electrosurgical snare without electrocautery.RESULTS: CSPs were completed for 232 of the 234 polyps. Two(0.9%) polyps could not be removed without electrocautery. Immediate postpolypectomy bleeding requiring endoscopic hemostasis occurred in eight lesions(3.4%; 95%CI: 1.1%-5.8%), but all were easily managed. The incidence of immediate bleeding after CSP for small polyps(6-9 mm) was significantly higher than that of diminutive polyps(≤ 5 mm; 15% vs 1%, respectively). Three(5%) patients complained of minor bleeding after the procedure but required no intervention. The incidence of delayed bleeding requiringendoscopic intervention was 0.0%(95%CI: 0.0%-1.7%). In total, 12% of the resected lesions could not be retrieved for pathological examination. Tumor involvement in the lateral margin could not be histologically assessed in 70(40%) lesions.CONCLUSION: CSP is feasible in Japan. However, immediate bleeding, retrieval failure and uncertain assessment of the lateral tumor margin should not be underestimated. Careful endoscopic diagnosis before and evaluation of the tumor residue after CSP are recommended when implementing CSP in Japan. | Yoji Takeuchi Takeshi Yamashina Noriko Matsuura Takashi Ito Mototsugu Fujii Kengo Nagai Fumi Matsui Tomofumi Akasaka Noboru Hanaoka Koji Higashino Hiroyasu Iishi Ryu Ishihara Henrik Thorlacius Noriya Uedo | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，17： | 14 |
| 12 | Promoted differentiation of cynomolgus monkey ES cells into hepatocyte-like cells by co-culture with mouse fetal liver-derived cells显示文摘AIM: To explore whether a co-culture of cynomolgus monkey embryonic stem (cES) cells with embryonic liver cells could promote their differentiation into hepatocytes. METHODS: Mouse fetal liver-derived cells (MFLCs) were prepared as adherent cells from mouse embryos on embryonic d (ED) 14, after which undifferentiated cES cells were co-cultured with MFLCs. The induction of cES cells along a hepatic lineage was examined in MFLC- assisted differentiation, spontaneous differentiation, and growth factors (GF) and chemicals-induced differentiations (GF-induced differentiation) using retinoic acid, leukemia inhibitory factor (LIF), FGF2, FGF4, hepatocyte growth factor (HGF), oncostatin M (OSM), and dexamethasone. RESULTS: The mRNA expression of α-fetoprotein, albumin (ALB), α-1-antitrypsin, and hepatocyte nuclear factor 4α was observed earlier in the differentiating cES cells co-cultured with MFLCs, as compared to cES cells undergoing spontaneous differentiation and those subjected to GF-induced differentiation. The expression of cytochrome P450 7a1, a possible marker for embryonic endoderm-derived mature hepatocytes, was only observed in cES cells that had differentiated in a co-culture with MFLCs. Further, the disappearance of Oct3/4, a representative marker of an undifferentiated state, was noted in cells co-cultured with MFLCs, but not in those undergoing spontaneous or GF-induced differentiation. Immunocytochemical analysis revealed an increased ratio of ALB-immunopositive cells among cES cells co-cultured with MFLCs, while glycogen storageand urea synthesis were also demonstrated. CONCLUSION: MFLCs showed an ability to induce cES cells to differentiate toward hepatocytes. The co-culture system with MFLCs is a useful method for induction of hepatocyte-like cells from undifferentiated cES cells. | Ko Saito Masahide Yoshikawa Yukiteru Ouji Kei Moriya Mariko Nishiofuku Shigehiko Ueda Noriko Hayashi Shigeaki Ishizaka Hiroshi Fukui | 2006 | World Journal of Gastroenterology2006，12，42： | 11 |
| 13 | Management of a large mucosal defect after duodenal endoscopic resection显示文摘Duodenal endoscopic resection is the most difficult type of endoscopic treatment in the gastrointestinal tract(GI) and is technically challenging because of anatomical specificities. In addition to these technical difficulties, this procedure is associated with a significantly higher rate of complication than endoscopic treatment in other parts of the GI tract. Postoperative delayed perforation and bleeding are hazardous complications, and emergency surgical intervention is sometimes required. Therefore, it is urgently necessary to establish a management protocol for preventing serious complications. For instance, the prophylactic closure of large mucosal defects after endoscopic resection may reduce the risk of hazardous complications. However, the size of mucosal defects after endoscopic submucosal dissection(ESD) is relatively large compared with the size after endoscopic mucosal resection, making it impossible to achieve complete closure using only conventional clips. The over-the-scope clip and polyglycolic acid sheets with fibrin gel make it possible to close large mucosal defects after duodenal ESD. In addition to the combination of laparoscopic surgery and endoscopic resection, endoscopic full-thickness resection holds therapeutic potential for difficult duodenal lesions and may overcome the disadvantages of endoscopic resection in the near future. This review aims to summarize the complications and closure techniques of large mucosal defects and to highlight some directions for management after duodenal endoscopic treatment. | Shintaro Fujihara Hirohito Mori Hideki Kobara Noriko Nishiyama Tae Matsunaga Maki Ayaki Tatsuo Yachida Tsutomu Masaki | 2016 | World Journal of Gastroenterology2016，22，29： | 10 |
| 14 | Eight-year survival after advanced gastric cancer treated with S-1 followed by surgery显示文摘We report a case of advanced gastric cancer, with cervical, axillary, and abdominal paraaortic lymph node metastases, that was successfully treated with chemotherapy and surgery. The disease was initially considered unresectable, and the patient was treated with orally administered S-1. Chemotherapy was effective, and all lymph node metastases disappeared after 6 courses. After 27 mo of chemotherapy, the patient underwent curative surgery, with subtotal gastrectomy and lymph node dissection. Histopathological examination revealed many viable poorly differentiated adenocarcinoma cells in the stomach, but no cancer cells in the lymph nodes. The patient is alive, without recurrence, 8 years later. This, therefore, is a case report of an 8-year survivor of advanced gastric cancer with distant lymph node metastasis. | Susumu Hijioka Keisho Chin Yasuyuki Seto Noriko Yamamoto Kiyohiko Hatake | 2010 | World Journal of Gastroenterology2010，16，22： | 10 |
| 15 | Pink-color sign in esophageal squamous neoplasia, and speculation regarding the underlying mechanism显示文摘AIM:To investigate the reasons for the occurrence of the pink-color sign of iodine-unstained lesions. METHODS:In chromoendoscopy, the pink-color sign of iodine-unstained lesions is recognized as useful for the diagnosis of esophageal squamous cell carcinoma. Patients with superficial esophageal neoplasms treated by endoscopic resection were included in the study. Areas of mucosa with and without the pink-color sign were evaluated histologically. The following histologic features that were possibly associated with the pinkcolor sign were evaluated. The keratinous layer and basal cell layer were classified as present or absent. Cellular atypia was classified as high grade, moderate grade or low grade, based on nuclear irregularity, mitotic figures, loss of polarity, chromatin pattern and nuclear/cytoplasmic ratio. Vascular change was assessed based on dilatation, tortuosity, caliber change and variability in shape. Vessels with these four findings were classified as positive for vascular change. Endoscopic images of the lesions were captured immediately after iodine staining, 2-3 min after iodine staining and after complete fading of iodine staining. Quantitative analysis of color changes after iodine staining was also performed. RESULTS:A total of 61 superficial esophageal neoplasms in 54 patients were included in the study. The lesions were located in the cervical esophagus in one case, the upper thoracic esophagus in 10 cases, the mid-thoracic esophagus in 33 cases, and the lower thoracic esophagus in 17 cases. The median diameter of the lesions was 20 mm (range:2-74 mm). Of the 61 lesions, 28 were classified as pink-color sign positive and 33 as pink-color sign negative. The histologic diagnosis was high-grade intraepithelial neoplasia (HGIN) or cancer invading into the lamina propria in 26 of the 28 pink-color sign positive lesions. There was a significant association between pink-color sign positive epithelium and HGIN or invasive cancer (P = 0.0001). Univariate analyses found that absence of the keratinous layer and cellular atypia were significantly associated with the pink-color sign. After Bonferroni correction, there were no significant associations between the pink-color sign and presence of the basal membrane or vascular change. Multivariate analyses found that only absence of the keratinous layer was independently associated with the pink-color sign (OR = 58.8, 95%CI:5.5-632).Quantitative analysis was performed on 10 superficial esophageal neoplasms with both pink-color sign positive and negative areas in 10 patients. Pink-color sign positive mucosa had a lower mean color value in the late phase (pinkish color) than in the early phase (yellowish color), and had similar mean color values in the late and final phases. These findings suggest that pinkcolor positive mucosa underwent color fading from the color of the iodine (yellow) to the color of the mucosa (pink) within 2-3 min after iodine staining. Pink-color sign negative mucosa had similar mean color values in the late and early phases (yellowish color), and had a lower mean color value in the final phase (pinkish color) than in the late phase. These findings suggest that pink-color sign negative mucosa did not undergo color fading during the 2-3 min after iodine staining, and underwent color fading only after spraying of sodium thiosulfate. CONCLUSION:The pink-color sign was associated with absence of the keratinous layer. This sign may be caused by early fading of iodine staining. | Ryu Ishihara Hiromitsu Kanzaki Hiroyasu Iishi Kengo Nagai Fumi Matsui Takeshi Yamashina Noriko Matsuura Takashi Ito Mototsugu Fujii Sachiko Yamamoto Noboru Hanaoka Yoji Takeuchi Koji Higashino Noriya Uedo Masaharu Tatsuta Yasuhiko Tomita Shingo Ishiguro | 2013 | World Journal of Gastroenterology2013，19，27： | 10 |
| 16 | Reduction effect of bacterial counts by preoperative saline lavage of the stomach in performing laparoscopic and endoscopic cooperative surgery显示文摘AIM:To investigate the effects of gastric lavage with2000 mL of saline in laparoscopic and endoscopic cooperative surgery.METHODS:Twenty two patients who were diagnosed with a gastric gastrointestinal stromal tumor were enrolled.In former term,irrigations of the stomach were conducted whenever it was necessary,not systematically(Non systemic lavage group).In latter term,the stomach was thoroughly cleaned with 2000 mL of saline using an endoscope with a water jet,and Duodenal balloon occlusion was conducted to prevent refluxedbile and pancreatic juice(Systemic lavage+balloon occlusion group).The gastric wall was sprayed with 20mL of distilled water,and 20 mL of gastric juice was collected in a sterile tube and submitted for culture.20mL of ascites was also collected from the laparoscopic ports and submitted for culture.We compared WBC,CRP,BT between two groups,and verify the reduction effect of bacterial counts in Systemic lavage+balloon occlusion group.RESULTS:WBC count before,1 d after,and 3 d after laparoscopic and endoscopic cooperative surgery(LECS)were 5060(95%CI:4250-9640),12140(6050-14110),and 6910(5320-12520)in Non systemic lavage group,4400(3660-7620),8910(6480-10980),and 5950(4840-7860)in Systemic lavage+balloon occlusion group.Significant differences between two groups at the day after LECS(P=0.029)and the 3 d after LECS(P=0.042).CRP levels in Non systemic lavage group and in Systemic lavage+balloon occlusion group were significantly different at the day after LECS(P=0.005)and the 3 d after LECS(P=0.028).BTs(℃)in Non systemic lavage group and in Systemic lavage+balloon occlusion group were also significantly different at the day after LECS(P=0.004)and the 3 d after LECS(P=0.006).In a logarithmic comparison,bacterial load before gastric lavage,after lavage,and ascites culture were 6.08(95%CI:4.04-6.97),0.48(0-0.85),and 0.21(0-0.56).The bacterial counts before and after gastric lavage were significantly suppressed(P=0.007),but no significant difference between gastric juice culture after lavage and ascites(P=0.154).CONCLUSION:Pre-LECS lavage with 2000 mL of saline exhibited a bacteria-reducing effect equivalent to disinfectants and obtained favorable results in terms of clinical symptoms and data. | Hirohito Mori Hideki Kobara Takaaki Tsushimi Shintaro Fujihara Noriko Nishiyama Tae Matsunaga Maki Ayaki Tatsuo Yachida Joji Tani Hisaaki Miyoshi Asahiro Morishita Tsutomu Masaki | 2014 | World Journal of Gastroenterology2014，20，42： | 9 |
| 17 | Long-term prognostic impact of circulating tumour cells in gastric cancer patients显示文摘AIM To analyse the long-term prognostic impact of circulating tumour cells(CTCs) in gastric cancer patients who underwent surgery. METHODS A 7.5-m L peripheral vein blood sample was obtained from each patient with treatment-negative gastric adenocarcinoma before surgery. OBP-401, a telomerasespecific, replication-selective, oncolytic adenoviral agent carrying the green fluorescent protein gene, was used to label CTCs. Correlations between the number of CTCs and clinical end points were evaluated. RESULTS The median follow-up period of the surviving patients with gastric cancer was 60 mo. The CTC number tended to increase concomitantly with disease progression. The overall survival of patients with more than five CTCs in 7.5-m L of peripheral blood was lower than that of patients with five or less CTCs, although the difference was not significant(P = 0.183). A significant difference in relapse-free survival was found between patients with more than five and those with five or less CTCs(P = 0.034).CONCLUSION A lower number of CTCs was correlated with higher relapse-free survival rates in patients. Detection of CTCs using OBP-401 may be useful for predicting prognosis in gastric cancer. | Hiroaki Ito Jun Sato Yukio Tsujino Noriko Yamaguchi Satoshi Kimura Keigo Gohda Katsuhiro Murakami Manabu Onimaru Tohru Ohmori Fumihiro Ishikawa Haruhiro Inoue | 2016 | World Journal of Gastroenterology2016，22，46： | 8 |
| 18 | Bleeding duodenal hemangioma: Morphological changes and endoscopic mucosal resection显示文摘Recently, the development of endoscopic procedures has increased the availability of minimally invasive treatments; however, there have been few case reports of duodenal hemangioma treated by endoscopic mucosal resection. The present report describes a case of duodenal hemangioma that showed various endoscopic changes over time and was treated by endoscopic mucosal resection. An 80-year-old woman presented with tarry stools and a loss of appetite. An examination of her blood revealed severe anemia, and her hemoglobin level was 4.2 g/dL. An emergency upper gastrointestinal endoscopy was performed. A red, protrusive, semipedunculated tumor (approximately 20 mm in diameter) with spontaneous bleeding on its surface was found in the superior duodenal angle. Given the semipedunculated appearance of the tumor, it was suspected to be an epithelial tumor with a differential diagnosis of hyperplastic polyp. The biopsy results suggested a telangiectatic hemangioma. Because this lesion was considered to be responsible for her anemia, endoscopic mucosal resection was performed for diagnostic and treatment purposes after informed consent was obtained. A histopathological examination of the resected specimen revealed dilated and proliferated capillary lumens of various sizes, which confirmed the final diagnosis of duodenal hemangioma. Neither anemia nor tumor recurrence has been observed since the endoscopic mucosal resection (approximately 1 year). Duodenal hemangiomas can be treated endoscopically provided that sufficient consideration is given to all of the possible treatment strategies. Interestingly, duodenal hemangiomas show morphological changes that are influenced by various factors, such as mechanical stimuli. | Noriko Nishiyama Hirohito Mori Hideki Kobara Shintarou Fujihara Takako Nomura Mitsuyoshi Kobayashi Tsutomu Masaki | 2012 | World Journal of Gastroenterology2012，18，22： | 7 |
| 19 | Two rare gastric hamartomatous inverted polyp cases suggest the pathogenesis of growth显示文摘Gastric hamartomatous inverted polyps(GHIP)are difficult to diagnose accurately because of inversion into the submucosal layer.GHIP are diagnosed using the pathological characteristics of the tumor,including the fibroblast cells,smooth muscle,nerve components,glandular hyperplasia,and cystic gland dilatation.Although Peutz-Jeghers syndrome,juvenile polyposis,and Cowden disease are hereditary,it is rare to encounter 2 cases of monostotic and asymptomatic gastric hamartomas.The pathogeneses of hamartomatous inverted polyps and inverted hyperplastic polyps remain controversial because of the paucity of reported cases.There are 3 hypotheses regarding the pathogenesis of complete gastric inverted polyps.Based on our experience with 2 successive,rare GHIP cases,we affirm the hypothesis that after a hamartomatous change occurs in the submucosal layer,some of these components are exposed to the gastric mucosa and,consequently,form a hypertrophic lesion.In Case 1,our hypothesis explains why a tiny hypertrophic change was first detected on the top of the submucosal tumor using a detailed narrow band imaging-magnified endoscopy.There was no confirmation that the milky white mucous and calcification structures were exuding directly from the biopsy site like Case 1,and in Case 2 the presence of this mucous was indirectly confirmed during an endoscopic submucosal dissection(ESD).Regarding the pathogenesis of GHIP,a submucosal hamartomatous change may occur prior to the growth of hypertrophic portions.An en bloc resection using ESD is recommended for treatment. | Hirohito Mori Hideki Kobara Takaaki Tsushimi Shintaro Fujihara Noriko Nishiyama Tae Matsunaga Maki Ayaki Tatsuo Yachida Tsutomu Masaki | 2014 | World Journal of Gastroenterology2014，20，19： | 7 |
| 20 | Determination of reactive oxygen generated from natural medicines and their antibacterial activity显示文摘Extracts of 16 natural medicine powders {Galla chinensis,Malloti cortex,Cassiae semen,Sophorae radix,Myricae cortex,Crataegi fructus,Gambit,Mume fructus,Geranii herba,Phellodendri cortex,Coptidis rhizoma,Swertiae herba,and Cinnamomi cortex) were assayed for reactive oxygen concentrations using the peroxyoxalate chemiluminescent detection system.High luminescence intensity was observed in Galla chinensis,Geranii herba,Malloti cortex,Myricae cortex,and Cinnamomi cortex.Additional experiments identified the reactive oxygen species as hydrogen peroxide.Galla chinensis generated 2.4 × 10^(-4) mol/L hydrogen peroxide from a 1 mg/mL solution.In bacterial growth tests,Galla chinensis extract had antibacterial activity against Escherichia coli.Staphylococcus aureus,Bacteroides thetaiotaomicron,Campylobacter sputorum biovar sputorum.Streptococcus salivarius thermophilus,Lactobacillus casei,and Bifidobacterium longum infantis.This antibacterial activity was decreased by the addition of catalase.It revealed that hydrogen peroxide which Galla chinensis produced participated in antibacterial activity. | Noriko Tajima Makiko Takasaki Haruka Fukamachi Takeshi Igarashi Yoshijiro Nakajima Hidetoshi Arakawa | 2016 | Journal of Pharmaceutical Analysis2016，6，4： | 7 |
