| 1 | Shear wave velocity is a useful marker for managing nonalcoholic steatohepatitis显示文摘AIM:To investigate whether a noninvasive measurement of tissue strain has a potential usefulness for management of nonalcoholic steatohepatitis(NASH).METHODS:In total 26 patients,23 NASHs and 3 normal controls were enrolled in this study.NASH was staged based on Brunt criterion.At a region of interest(ROI),a shear wave was evoked by implementing an acoustic radiation force impulse(ARFI),and the propagation velocity was quantif ied.RESULTS:Shear wave velocity(SWV) could be reproducibly quantified at all ROIs in all subjects except for 4 NASH cases,in which a reliable SWV value was not calculated at several ROIs.An average SWV of 1.34 ± 0.26 m/s in fibrous stage 0-1 was significantly slower than 2.20 ± 0.74 m/s and 2.90 ± 1.01 m/s in stages 3 and 4,respectively,but was not significantly different from 1.79 ± 0.78 m/s in stage 2.When a cutoff value was set at 1.47 m/s,receiver operating characteristic analysis showed significance to dissociate stages 3 and 4 from stage 0-1(P=0.0092) with sensitivity,specificity and area under curve of 100%,75% and 94.2%,respectively.In addition,the correlation between SWV and hyaluronic acid was significant(P<0.0001),while a tendency toward negative correlation was observed with serum albumin(P=0.053).CONCLUSION:The clinical implementation of ARFI provides noninvasive repeated evaluations of liver stiffness at an arbitrary position,which has the potential to shed new light on NASH management. | Akihiko Osaki Tomoyuki Kubota Takeshi Suda Masato Igarashi Keisuke Nagasaki Atsunori Tsuchiya Masahiko Yano Yasushi Tamura Masaaki Takamura Hirokazu Kawai Satoshi Yamagiwa Toru Kikuchi Minoru Nomoto Yutaka Aoyagi | 2010 | World Journal of Gastroenterology2010，16，23： | 30 |
| 2 | Criteria for the diagnosis and severity stratification of acute pancreatitis显示文摘Recent diagnostic and therapeutic progress for severe acute pancreatitis(SAP)remarkably decreased the casemortality rate.To further decrease the mortality rate of SAP,it is important to precisely evaluate the severity at an early stage,and initiate appropriate treatment as early as possible.Research Committee of Intractable Diseases of the Pancreas in Japan developed simpler criteria combining routinely available data with clinical signs.Severity can be evaluated by laboratory examinations or by clinical signs,reducing the defect values of the severity factors.Moreover,the severity criteria considered laboratory/clinical severity scores and contrastenhanced computed tomography(CE-CT)findings as independent risk factors.Thus,CE-CT scans are not necessarily required to evaluate the severity of acute pancreatitis.There was no fatal case in mild AP diagnosed by the CE-CT severity score,whereas case-mortality rate in those with SAP was 14.8%.Case-mortality of SAP that fulfilled both the laboratory/clinical and the CE-CT severity criteria was 30.8%.It is recommended,therefore,to perform CE-CT examination to clarify the prognosis in those patients who were diagnosed as SAP by laboratory/clinical severity criteria.Because the mortality rate of these patients with SAP is high,such patients should be transferred to advanced medical units. | Makoto Otsuki Kazunori Takeda Seiki Matsuno Yasuyuki Kihara Masaru Koizumi Masahiko Hirota Tetsuhide Ito Keisho Kataoka Motoji Kitagawa Kazuo Inui Yoshifumi Takeyama | 2013 | World Journal of Gastroenterology2013，19，35： | 24 |

| 4 | New Technologies and Systems for High Quality Citrus Fruit Production, Labor-saving and Orchard Construction in Mountain Areas of Japan显示文摘Novel technologies have been necessary for improving fruit quality and productivity of citrus, labor-saving and orchard conservation on steep slope lands since aging of growers and decrease in the number of successors is remarkable in mountain areas of southwestern Japan. The purpose of this paper is to introduce new technologies for improving citrus production that have been developed in recent years. A new fruit quality control system using drip irrigation and liquid fertilization technique combined with year-round plastic mulching was developed, and it enables high quality and stable citrus fruit production. Water and/or nutrient solution is automatically supplied through drip tubes that are laid under the mulching sheets to give adequate water stress, so as to improve sugar and acid content of fruit. A new transportation system for steep sloping citrus orchards, which is a combination of the monorail system and contour narrow paths, was suggested. A small walking cultivator was developed to explain the procedure of narrow path excavation. After introducing the narrow path, working hours for fertilizer and chemical herbicide application were reduced. Disaster prevention mapping of citrus orchards on slope lands was developed based on computer-aided seepage estimation and topographic data. The mapping can show zones of both ascending flow and descending flow of underground water during heavy rains in citrus orchards. The mapping is considered to be effective for the management of orchards and prevention of erosion on slope lands. | Kunihisa MORINAGA Osamu SUMIKAWA Osamu KAWAMOTO Hiroyasu YOSHIKAWA Seiji NAKAO Masahiko SHIMAZAKI Shin-no-suke KUSABA Norihiro HOSHI | 2005 | Journal of Mountain Science2005，2，1： | 21 |
| 5 | Improving recognition of hepatic perivascular epithelioid cell tumor:Case report and literature review显示文摘A 58-year-old man presented with the chief complaint of abdominal bloating and was incidentally found to have a liver tumor.As diagnostic imaging studies could not rule out malignancy,the patient underwent partial resection of segment 3 of the liver.The lesion pathologically showed eosinophilic proliferation,in addition to immunohistochemical positivity for human melanoma black 45 and Melan-A,thereby leading to the diagnosis of a hepatic perivascular epithelioid cell tumor(PEComa).A PEComa arising from the liver is relatively rare.Moreover,the name ‘PEComa' has not yet been widely recognized,and the same disease entity has been called epithelioid angiomyolipoma(EAML),further diminishing the recognition of PEComa.In addition,PEComa imaging findings mimic those of malignant liver tumors,and clinically,this tumor tends to enlarge.Therefore,a PEComa is difficult to diagnose.We conducted a systematic review of PEComa and EAML cases and discuss the results,including findings useful for differentiating perivascular epithelioid cell tumors from malignant liver tumors. | Toshiya Maebayashi Katsumi Abe Takuya Aizawa Masakuni Sakaguchi Naoya Ishibashi Osamu Abe Tadatoshi Takayama Hisashi Nakayama Shunichi Matsuoka Kazushige Nirei Hitomi Nakamura Masahiro Ogawa Masahiko Sugitani | 2015 | World Journal of Gastroenterology2015，21，17： | 20 |
| 6 | Management of hepatitis B virus infection during treatment for hepatitis B virus-related hepatocellular carcinoma显示文摘Although liver resection is considered the most effective treatment for hepatocellular carcinoma(HCC), treatment outcomes are unsatisfactory because of the high rate of HCC recurrence. Since we reported hepatitis B e-antigen positivity and high serum hepatitis B virus(HBV) DNA concentrations are strong risk factors for HCC recurrence after curative resection of HBV-related HCC in the early 2000 s, many investigators have demonstrated the effects of viral status on HCC recurrence and post-treatment outcomes. These findings suggest controlling viral status is important to prevent HCC recurrence and improve survival after curative treatment for HBV-related HCC. Antiviral therapy after curative treatment aims to improve prognosis by preventing HCC recurrence and maintaining liver function. Therapy with interferon and nucleos(t)ide analogs may be useful for preventing HCC recurrence and improving overall survival in patients who have undergone curative resection for HBV-related HCC. In addition, reactivation of viral replication can occur after liver resection for HBV-related HCC. Antiviral therapy can be recommended for patients to prevent HBV reactivation. Nevertheless, further studies are required to establish treatment guidelines for patients with HBVrelated HCC. | Shoji Kubo Shigekazu Takemura Shogo Tanaka Hiroji Shinkawa Takayoshi Nishioka Akinori Nozawa Masahiko Kinoshita Genya Hamano Tokuji Ito Yorihisa Urata | 2015 | World Journal of Gastroenterology2015，21，27： | 19 |
| 7 | Acute development of collateral circulation and therapeutic prospects in ischemic stroke显示文摘In acute ischemic stroke,collateral circulation plays an important role in maintaining blood flow to the tissue that is at risk of progressing into ischemia,and in increasing the successful recanalization rate without hemorrhagic transformation.We have reported that well-developed collateral circulation is associated with smaller infarct volume and better long-term neurological outcome,and it disappears promptly once the effective recanalization is achieved.Contrary to the belief that collateral vessels develop over time in chronic stenotic condition,there exists a phenomenon that collateral circulation develops immediately in acute stenosis or occlusion of the arteries and it seems to be triggered by fluid shear stress,which occurs between the territories of stenotic/occluded arteries and those fed by surrounding intact arteries.We believe that this acute development of collateral circulation is a target of novel therapeutics in ischemic stroke and refer our recent attempt in enhancing collateral circulation by modulating sphingosine-1-phosphate receptor 1,which is a known shear-stress mechanosensing protein. | Eri Iwasawa Masahiko Ichijo Satoru Ishibashi Takanori Yokota | 2016 | Neural Regeneration Research2016，11，3： | 19 |

| 9 | Optimal treatment for Siewert type Ⅱ and Ⅲ adenocarcinoma of the esophagogastric junction: A retrospective cohort study with long-term follow-up显示文摘AIM To determine the optimal treatment strategy for Siewert type Ⅱ and?Ⅲ?adenocarcinoma of the esophagogastric junction.METHODS We retrospectively reviewed the medical records of 83 patients with Siewert type?Ⅱ?and?Ⅲ?adenocarcinoma of the esophagogastric junction and calculated both an index of estimated benefit from lymph node dissection for each lymph node(LN) station and a lymph node ratio(LNR: ratio of number of positive lymph nodes to the total number of dissected lymph nodes). We used Cox proportional hazard models to clarify independent poor prognostic factors. The median duration of observation was 73 mo.RESULTS Indices of estimated benefit from LN dissection were as follows, in descending order: lymph nodes(LN) along the lesser curvature, 26.5; right paracardial LN, 22.8; left paracardial LN, 11.6; LN along the left gastric artery, 10.6. The 5-year overall survival(OS) rate was 58%. Cox regression analysis revealed that vigorous venous invasion(v2, v3)(HR = 5.99; 95%CI: 1.71-24.90) and LNR of > 0.16(HR = 4.29, 95%CI: 1.79-10.89) were independent poor prognostic factors for OS.CONCLUSION LN along the lesser curvature, right and left paracardial LN, and LN along the left gastric artery should be dissected in patients with Siewert type?Ⅱ?or?Ⅲ?adenoca rcinoma of the esophagogastric junction. Patients with vigorous venous invasion and LNR of > 0.16 should be treated with aggressive adjuvant chemotherapy to improve survival outcomes. | Kei Hosoda Keishi Yamashita Hiromitsu Moriya Hiroaki Mieno Masahiko Watanabe | 2017 | World Journal of Gastroenterology2017，23，15： | 19 |
| 10 | Treatment strategy for gastric non-invasive intraepithelial neoplasia diagnosed by endoscopic biopsy显示文摘Treatment strategies,whether as follow-up or'total incisional biopsy'for gastric noninvasive intraepithelial neoplasia diagnosed by examination of an endoscopic forceps biopsy specimen,are controversial due to problems associated with the diagnostic accuracy of endoscopic forceps biopsy and questions about the safety and efficacy of endoscopic treatment.Based on the histological findings of the biopsy specimen,it is difficult to differentiate between reactive or regenerative changes,inflammation and neoplastic changes,intraepithelial and invasive tumors.Therefore,gastric neoplasia diagnosed as noninvasive intraepithelial often develop into invasive carcinoma during follow-up.Recent advances in endoscopic modalities and treatment devices,such as image-enhanced endoscopy and highfrequency generators,may make endoscopic treatment,such as endoscopic submucosal dissection(ESD),a therapeutic option for gastric intraepithelial neoplasia,including low-grade neoplasms.Future studies are required to evaluate whether ESD is a valid strategy for gastric intraepithelial neoplasm with regard to safety and cost effectiveness. | Tsutomu Nishida Shusaku Tsutsui Motohiko Kato Takuya Inoue Shunsuke Yamamoto Yoshito Hayashi Tomofumi Akasaka Takuya Yamada Shinichiro Shinzaki Hideki Iijima Masahiko Tsujii Tetsuo Takehara | 2011 | World Journal of Gastrointestinal Pathophysiology2011，2，6： | 18 |
| 11 | Sentinel lymph node navigation surgery for early stage gastric cancer显示文摘We attempted to evaluate the history of sentinel node navigation surgery(SNNS),technical aspects,tracers,and clinical applications of SNNS using Infrared Ray Electronic Endoscopes(IREE)combined with Indocyanine Green(ICG).The sentinel lymph node(SLN)is defined as a first lymph node(LN)which receives cancer cells from a primary tumor.Reports on clinical application of SNNS for gastric cancers started to appear since early 2000s.Two prospective multicenter trials of SNNS for gastric cancer have also been accomplished in Japan.Kitagawa et al reported that the endoscopic dual(dye and radioisotope)tracer method for SN biopsy was confirmed acceptable and effective when applied to the early-stage gastric cancer(EGC).We have previously reported the usefulness of SNNS in gastrointestinal cancer using ICG as a tracer,combined with IREE(Olympus Optical,Tokyo,Japan)to detect SLN.LN metastasis rate of EGC is low.Hence,clinical application of SNNS for EGC might lead us to avoid unnecessary LN dissection,which could preserve the patient’s quality of life after operation.The most ideal method of SNNS should allow secure and accurate detection of SLN,and real time observation of lymphatic flow during operation. | Norio Mitsumori Hiroshi Nimura Naoto Takahashi Masahiko Kawamura Hiroaki Aoki Atsuo Shida Nobuo Omura Katsuhiko Yanaga | 2014 | World Journal of Gastroenterology2014，20，19： | 15 |
| 12 | Retroperitoneal fibrosis associated with immunoglobulin G4-related disease显示文摘Retroperitoneal fibrosis is a rare disease characterized by the development of inflammation and fibrosis in the soft tissues of the retroperitoneum and other abdominal organs.Retroperitoneal fibrosis can be of 2 types:idiopathic and secondary.The recently advocated concept and diagnostic criteria of immunoglobulin G4(IgG4)-related disease,derived from research on autoimmune pancreatitis(AIP),has led to widespread recognition of retroperitoneal fibrosis as a condition caused by IgG4-related disease.We now know that previously diagnosed idiopathic retroperitoneal fibrosis includes IgG4-related disease;however,the actual prevalence is unclear.Conversely,some reports on AIP suggest that retroperitoneal fibrosis is concurrently found in about 10% of IgG4-related disease.Because retroperitoneal fibrosis has no specific symptoms,diagnosis is primarily based on diagnostic imaging(computed tomography and magnetic resonance imaging),which is also useful in evaluating the effect of therapy.Idiopathic retroperitoneal fibrosis can occur at different times with other lesions of IgG4-related disease including AIP.Thus,the IgG4 assay is recommended to diagnose idiopathic retroperitoneal fibrosis.High serum IgG4 levels should be treated and monitored as a symptom of IgG4-related disease.The first line of treatment for retroperitoneal fibrosis is steroid therapy regardless of its cause.For patients with concurrent AIP,i.e.,IgG4-related retroperitoneal fibrosis,the starting dose of steroid is usually 30-40 mg/d.The response to steroid therapy is generally favorable.In most cases,the pancreatic lesion and retroperitoneal fibrosis improve after the initial treatment.However,the epidemiology,treatment for recurring retroperitoneal fibrosis,and long-term prognosis are still largely unknown.Further analysis of such cases and research are necessary. | Nao Fujimori Tetsuhide Ito Hisato Igarashi Takamasa Oono Taichi Nakamura Yusuke Niina Masayuki Hijioka Lingaku Lee Masahiko Uchida Ryoichi Takayanagi | 2013 | World Journal of Gastroenterology2013，19，1： | 14 |
| 13 | First-line eradication for Helicobacter pylori-positive gastritis by esomeprazole-based triple therapy is influenced by CYP2C19 genotype显示文摘AIM: To evaluate the effect of first line esomeprazole(EPZ)-based triple therapy on Helicobacter pylori(H. pylori) eradication.METHODS: A total of 80 Japanese patients with gastritis who were diagnosed as positive for H. pylori infection by endoscopic biopsy-based or ^(13)C-urea breath tests were included in this study. The average age of the patients was 57.2 years(male/female, 42/38). These patients were treated by first-line eradication therapy with EPZ 40 mg/d, amoxicillin 1500 mg/d, and clarithromycin 400 mg/d for 7 d. All drugs were given twice per day. Correlations between H. pylori eradication, CYP2C19 genotype, and serum pepsinogen(PG) level were analyzed. This study was registered with the UMIN Clinical Trials Registry(UMIN000009642).RESULTS: The H. pylori eradication rates by EPZbased triple therapy evaluated by intention-to-treat and per protocol were 67.5% and 68.4%, respectively, which were similar to triple therapies with other first-generation proton pump inhibitors(PPIs). The eradication rates in three different CYP2C19 genotypes, described as extensive metabolizer(EM), intermediate metabolizer, and poor metabolizer, were 52.2%, 72.1%, and 84.6%, respectively. The H. pylori eradication rate was significantly lower in EM than non-EM(P < 0.05). The serum PG?Ⅰ?level and PG?Ⅰ/Ⅱ ratio were significantly increased after eradication of H. pylori(P < 0.01), suggesting that gastric atrophy was improved by H. pylori eradication. Thus, first-line eradication by EPZbased triple therapy for patients with H. pylori-positive gastritis was influenced by CYP2C19 genotype, and the eradication rate was on the same level with other firstgeneration PPIs in the Japanese population.CONCLUSION: The results from this study suggest that there is no advantage to EPZ-based triple therapy on H. pylori eradication compared to other firstgeneration PPIs. | Yoshimasa Saito Hiroshi Serizawa Yukako Kato Masaru Nakano Masahiko Nakamura Hidetsugu Saito Hidekazu Suzuki Takanori Kanai | 2015 | World Journal of Gastroenterology2015，21，48： | 13 |
| 14 | Comparative study of esomeprazole and lansoprazole in triple therapy for eradication of Helicobacter pylori in Japan显示文摘AIM:To evaluate the efficacy and safety of esomeprazole-based triple therapy compared with lansoprazole therapy as first-line eradication therapy for patients with Helicobacter pylori(H.pylori)in usual post-marketing use in Japan,where the clarithromycin(CAM)resistance rate is 30%.METHODS:For this multicenter,randomized,openlabel,non-inferiority trial,we recruited patients(≥20years of age)with H.pylori infection from 20 hospitals in Japan.We randomly allocated patients to esomeprazole therapy(esomeprazole 20 mg,CAM 400 mg,amoxicillin(AC)750 mg for the first 7 d,with all drugs given twice daily)or lansoprazole therapy(lansoprazole30 mg,CAM 400 mg,AC 750 mg for the first 7 d,with all drugs given twice daily)using a minimization method with age,sex,and institution as adjustment factors.Our primary outcome was the eradication rate by intention-to-treat(ITT)and per-protocol(PP)analyses.H.pylori eradication was confirmed by a urea breath test from 4 to 8 wk after cessation of therapy.RESULTS:ITT analysis revealed the eradication rates of 69.4%(95%CI:61.2%-76.6%)for esomeprazole therapy and 73.9%(95%CI:65.9%-80.6%)for lansoprazole therapy(P=0.4982).PP analysis showed eradication rate of 76.9%(95%CI:68.6%-83.5%)for esomeprazole therapy and 79.8%(95%CI:71.9%-86.0%)for lansoprazole therapy(P=0.6423).There were no differences in adverse effects between the two therapies.CONCLUSION:Esomeprazole showed non-inferiority and safety in a 7 day-triple therapy for eradication of H.pylori compared with lansoprazole. | Tsutomu Nishida Masahiko Tsujii Hirohisa Tanimura Shusaku Tsutsui Shingo Tsuji Akira Takeda Atsuo Inoue Hiroyuki Fukui Toshiyuki Yoshio Osamu Kishida Hiroyuki Ogawa Masahide Oshita Ichizo Kobayashi Shinichiro Zushi Makoto Ichiba Naoto Uenoyama Yuichi Yasunaga Ryu Ishihara Mamoru Yura Masato Komori Satoshi Egawa Hideki Iijima Tetsuo Takehara | 2014 | World Journal of Gastroenterology2014，20，15： | 13 |

| 16 | Hepatic schwannoma:Imaging findings on CT,MRI and contrast-enhanced ultrasonography显示文摘A primary benign schwannoma of the liver is extremely rare and is difficult to preoperatively discriminate from a malignant tumor.We compared the imaging and pathological findings,and examined the possibility of preoperatively diagnosing a benign liver schwannoma.A 72-year-old woman was admitted to our hospital because of a 4.6-cm mass in the liver.A malignant tumor was suspected,and a right hepatectomy was performed.After this,the diagnosis of a primary benign schwannoma of the liver was made through pathological examination.Contrast-enhanced ultrasonography(CEUS) with Sonazoid showed minute blood flows into the septum and solid areas of the tumor in the vascular phase;most likely due to increased arterial flow associated with infiltration of chronic inflammatory cells.In the postvascular phase,CEUS showed contrast defect of cystic areas and delayed enhancement of solid areas;most likely due to aggregation of siderophores.Because discriminating between a benign and malignant schwannoma of the liver is difficult,surgery is generally recommended.However,the two key findings from CEUS may be useful in discriminating ancient schwannoma by recognizing the hemorrhage involved in the secondary degeneration and aggregation of siderophores. | Yu Ota Kazunobu Aso Kenji Watanabe Takahiro Einama Koji Imai Hidenori Karasaki Ryuji Sudo Yosui Tamaki Mituyoshi Okada Yosihiko Tokusashi Toru Kono Naoyuki Miyokawa Masakazu Haneda Masahiko Taniguchi Hiroyuki Furukawa | 2012 | World Journal of Gastroenterology2012，18，35： | 11 |
| 17 | Hepatic clearance measured with ^(99m)Tc-GSA single-photon emission computed tomography to estimate liver fibrosis显示文摘AIM: To evaluate the clinical utility of hepatic clearance(HC) measured with technetium-99m-diethylenetriaminepenta-acetic acid-galactosyl human serum albumin(99mTc-GSA) single-photon emission computed tomography(SPECT) to estimate the degree of liver fibrosis.METHODS:Seventy-eight consecutive patients who underwent initial hepatectomy due to hepatocellular carcinoma were enrolled in this study.Indocyanine green clearance(ICG R15),quantitative indices estimated by 99mTc-GSA[the receptor index(LHL15 and HH15)and HC via SPECT analysis],and conventional liver function tests were performed before hepatectomy.Correlations among the quantitative indices for liver functional reserve,conventional liver function tests,andthe degree of liver fibrosis were evaluated.RESULTS:The degree of liver fibrosis was correlated with ICG R15,HH15,LHL15,and HC.HC showed the best correlation with conventional liver function tests.According to multivariate analysis,HC and LHL15 were significant independent predictors of severe fibrosis.HC was the most valuable index for predicting severe fibrosis.CONCLUSION:HC measured with 99mTc-GSA SPECT is a reliable index for assessing liver fibrosis before hepatectomy. | Masahiko Taniguchi Atsutaka Okizaki Kenji Watanabe Koji Imai Koichiro Uchida Takahiro Einama Noriyuki Shuke Naoyuki Miyokawa Hiroyuki Furukawa | 2014 | World Journal of Gastroenterology2014，20，44： | 11 |
| 18 | Trend in gastric cancer:35 years of surgical experience in Japan显示文摘AIM:To investigate the trend in gastric cancer surgery in the context of rapid therapeutic advancement in Japan and East Asia.METHODS:A retrospective analysis was performed on 4163 patients who underwent gastric resection for gastric cancer with histological confirmation between 1971 and 2007 at the surgical unit in Kitasato University Hospital,to determine the trend in gastric cancer requiring surgery.RESULTS:Gastric cancer requiring surgical resection increased in our hospital,but the incidence adjusted for population was constant during the observed pe-riod.Interestingly,the ratio of diffuse type/intestinal type gastric cancer was unexpectedly unchanged,and that of advanced/early gastric cancer(EGC)was,however,markedly reduced,while the actual incidence of potentially curative advanced gastric cancer tended to decrease.The incidence of EGC requiring surgery tended to increase as a whole,which is consistent with increased prevalence of endoscopic surveillance.As a result,overall survival and mortality of gastric cancer requiring gastric resection has recently markedly improved.CONCLUSION:In Japan,planned interventions may improve surgical gastric cancer mortality,but an unexpected trend of persistent existence of intestinal type cancer suggests the need for more robust medical intervention. | Keishi Yamashita Shinichi Sakuramoto Masayuki Nemoto Tomotaka Shibata Hiroaki Mieno Natsuya Katada Shiroh Kikuchi Masahiko Watanabe | 2011 | World Journal of Gastroenterology2011，17，29： | 11 |

| 20 | Natural regression of fibrosis in chronic hepatitis B显示文摘The fibrosis of liver cirrhosis was considered to be irreversible before the anti-viral drugs showed that it is reversible when they lead to continuous suppression of viral replication and inflammation. However, several reports previously showed that fibrosis of type B liver cirrhosis was almost completely absorbed after the natural remission of chronic inflammation. This phenomenon might not be limited to exceptional patients, but rather occur commonly, considering the dynamic clinical features of chronic hepatitis B(CHB), where inactive carrier stage normally follows aggravation of hepatitis and progression of fibrosis at the time of HBe Ag seroconversion. Thus, fibrosis levels of CHB as a hepatocellular carcinoma(HCC)-surveillance marker, particularly those of the inactive stage, could be underestimated, because some of them might have been(pre)cirrhotic in the past and recovered with the natural regression of fibrosis. We argue that cirrhosisinduced HCC mechanisms, rather than direct action of viral genome, may be more common than generally considered in CHB patients. This may have some impact on reconsidering the surveillance rationale for HCC in CHB, from where advanced HCCs tended to be missed. In addition, a molecular marker to assess the cancer-prone characteristics of the liver will definitely be needed to resolve the issue. | Shogo Ohkoshi Haruka Hirono Kazuhiko Watanabe Katsuhiko Hasegawa Kenya Kamimura Masahiko Yano | 2016 | World Journal of Gastroenterology2016，22，24： | 8 |
