| 1 | Hepatitis B virus pathogenesis: Fresh insights into hepatitis B virus RNA显示文摘Hepatitis B virus(HBV) is still a worldwide health concern. While divergent factors are involved in its pathogenesis, it is now clear that HBV RNAs, principally templates for viral proteins and viral DNAs, have diverse biological functions involved in HBV pathogenesis. These functions include viral replication, hepatic fibrosis and hepatocarcinogenesis. Depending on the sequence similarities, HBV RNAs may act as sponges for host mi RNAs and may deregulate mi RNA functions, possibly leading to pathological consequences. Some parts of the HBV RNA molecule may function as viralderived mi RNA, which regulates viral replication. HBV DNA can integrate into the host genomic DNA and produce novel viral-host fusion RNA, which may have pathological functions. To date, elimination of HBVderived covalently closed circular DNA has not been achieved. However, RNA transcription silencing may be an alternative practical approach to treat HBVinduced pathogenesis. A full understanding of HBV RNA transcription and the biological functions of HBV RNA may open a new avenue for the development of novel HBV therapeutics. | Kazuma Sekiba Motoyuki Otsuka Motoko Ohno Mari Yamagami Takahiro Kishikawa Tatsunori Suzuki Rei Ishibashi Takahiro Seimiya Eri Tanaka Kazuhiko Koike | 2018 | World Journal of Gastroenterology2018，24，21： | 10 |
| 2 | Circulating RNAs as new biomarkers for detecting pancreatic cancer显示文摘Pancreatic cancer remains difficult to treat and has a high mortality rate.It is difficult to diagnose early mainly due to the lack of screening imaging modalities and specific biomarkers.Consequently,it is important to develop biomarkers that enable the detection of early stage tumors.Emerging evidence is accumulating that tumor cells release substantial amounts of RNA into the bloodstream that strongly resist RNases in the blood and are present at sufficient levels for quantitative analyses.These circulating RNAs are upregulated in the serum and plasma of cancer patients,including those with pancreatic cancer,compared with healthy controls.The majority of RNA biomarker studies have assessed circulating microRNAs(miRs),which are often tissue-specific.There are few reports of the tumorspecific upregulation of other types of small noncoding RNAs(ncRNAs),such as small nucleolar RNAs and Piwi-interacting RNAs.Long ncRNAs(IncRNAs),such as HOTAIR and MALAT1,in the serum/plasma of pancreatic cancer patients have also been reported as diagnostic and prognostic markers.Among tissuederived RNAs,some miRs show increased expression even in pre-cancerous tissues,and their expression profiles may allow for the discrimination between a chronic inflammatory state and carcinoma.Additionally,some miRs and IncRNAs have been reported with significant alterations in expression according to disease progression,and they may thus represent potential candidate diagnostic or prognostic biomarkers that may be used to evaluate patients once detection methods in peripheral blood are well established.Furthermore,recent innovations in high-throughput sequencing techniques have enabled the discovery of unannotated tumor-associated ncRNAs and tumor-specific alternative splicing as novel and specific biomarkers of cancers.Although much work is required to clarify the release mechanism,origin of tumor-specific circulating RNAs,and selectivity of carrier complexes,and technical advances must also be achieved,such as creating a consensus normalization protocol for quantitative data analysis,circulating RNAs are largely unexplored and might represent novel clinical biomarkers. | Takahiro Kishikawa Motoyuki Otsuka Motoko Ohno Takeshi Yoshikawa Akemi Takata Kazuhiko Koike | 2015 | World Journal of Gastroenterology2015，21，28： | 8 |
| 3 | Diagnostic and therapeutic application of noncoding RNAs for hepatocellular carcinoma显示文摘Micro RNAs(mi RNAs) are small,noncoding RNA molecules that regulate gene expression posttranscriptionally,targeting thousands of messenger RNAs. Long noncoding RNAs(lnc RNAs),another class of noncoding RNAs,have been determined to be also involved in transcription regulation and translation of target genes. Since deregulated expression levels or functions of miR NAs and lncR NAs in hepatocellular carcinoma(HCC) are frequently observed,clinical use of noncoding RNAs for novel diagnostic and therapeutic applications in the management of HCCs is highly and emergently e xpe c t e d. H e r e,we s ummar iz e r e c e nt f indings regarding deregulated mi RNAs and lnc RNAs for their potential clinical use as diagnostic and prognostic biomarkers of HCC. Specifically,we emphasize the deregulated expression levels of such noncoding RNAs in patients' sera as noninvasive biomarkers,a field that requires urgent improvement in the clinical surveillance of HCC. Since nucleotide-based strategies are being applied to clinical therapeutics,we further summarize clinical and preclinical trials using oligonucleotides involving the use of miR NAs and small interfering RNAs against HCC as novel therapeutics. Finally,we discuss current open questions,which must be clarified in the near future for realistic clinical applications of these new strategies. | Chikako Shibata Motoyuki Otsuka Takahiro Kishikawa Motoko Ohno Takeshi Yoshikawa Akemi Takata Kazuhiko Koike | 2015 | World Journal of Hepatology2015，7，1： | 7 |
| 4 | Novel therapeutic approaches for hepatitis B virus covalently closed circular DNA显示文摘Hepatitis B virus(HBV) infection is a major global health problem. Although current therapies, such as the use of nucleos(t)ide analogs, inhibit HBV replication efficiently, they do not eliminate covalently closed circular DNA(ccc DNA), which persists in hepatocyte nuclei. As HBV ccc DNA is a viral transcription template, novel therapeutic approaches to directly target HBV ccc DNA are necessary to completely eradicate persistent HBV infections. HBV ccc DNA levels in HBV-infected human liver cells are extremely low; thus, more reliable and simple measurement methods are needed to correctly monitor their levels during therapeutic treatment. Although reverse transcription-polymerase chain reaction or Southern blot procedures are currently used in research studies, these methods are not completely reliable and are also time-consuming and labor-intensive. Genome editing technologies, such as zinc finger nucleases, transcription activator-like effector nucleases, and the clustered regularly interspaced short palindromic repeats/Cas9(CRISPR/Cas9) system, which are designed to target specific DNA sequences, represent highly promising potential therapeutic tools. In particular, the CRISPR/Cas9 system is an easily customizable sequencespecific nuclease with high flexibility and may be the most feasible approach to target HBV ccc DNA. Further research to develop easier, safer, and more effective protocols should be pursued. | Motoko Ohno Motoyuki Otsuka Takahiro Kishikawa Takeshi Yoshikawa Akemi Takata Kazuhiko Koike | 2015 | World Journal of Gastroenterology2015，21，23： | 5 |
| 5 | Association between tear film break up time and blink interval in visual display terminal users显示文摘AIM:To investigate the association between tear film break up time(TBUT)and blinking interval in visual display terminal(VDT)users.METHODS:Nine hundred and thirty VDT users underwent dry eye testing,and functional visual acuity(FVA)test.The blinking interval during FVA was compared with TBUT.Subjects with longer blinking interval than TBUT were considered as unstable tear film.Logistic regression analysis revealed the risk factors for unstable tear group.RESULTS:Among 930 workers,858 subjects(92.3%)participated in this study.Almost 80% of the subjects were categorized into the unstable tear group.Unstable tear group has significantly lower Schirmer values and TBUT(17.5±11.6 vs 21.1±11.5 mm,3.7±2.6 vs 5.7±2.7s,both P<0.001).There were no significant differences in epithelial staining or severity of symptoms.Logistic regression showed that over 40y was a risk for being unstable tear group[odds ratio(OR)=1.53;95%confidence interval(CI)=1.06-2.20].Contact lens use was protective factor for being in the unstable tear group(OR=0.37;95%CI=0.26-0.53).CONCLUSION:Subjects with shorter TBUT than blinking interval are prevalent among VDT users.Subjects over the age of 40 shows an increased risk for unstable tear film. | Miki Uchino Motoko Kawashima Yuichi Uchino Kazuo Tsubota Norihiko Yokoi | 2018 | International Journal of Ophthalmology(English edition)2018，11，10： | 5 |
| 6 | Gender differences in adolescent dry eye disease:a health problem in girls显示文摘AIM: To evaluate the signs and symptoms of dry eye disease(DED) in adolescents. METHODS: This was a cross-sectional, case-control study and outpatients aged 10 to 19y were recruited from six eye clinics of various practices and locations in Japan, and 253 non-DED subjects and 70 DED patients were enrolled. Participants were examined for DED-related signs. Patients were also interviewed to ascertain the presence or absence of six common DED-related symptoms: dryness, irritation, pain, eye fatigue, blurring, and photophobia. Main outcome measures were differences in signs and symptoms of dry eye disease between boys and girls.RESULTS: Of the 323 adolescents recruited, 70(21.7%) were diagnosed with DED. Significant differences between the non-DED and DED groups were found for short tear break-up time(BUT; ≤5s; P=0.000) and superficial punctate keratopathy(SPK; staining score ≥3; P=0.000). Late adolescent girls reported fewer symptoms than late adolescent boys, although their DED-related signs were worse compared to other groups. The prevalence and severity of DED were similar in the Tokyo area compared with suburban and local areas but myopic errors were worse. CONCLUSION: We find that adolescents reported symptoms of DED similar to those found in adults, and the majority have short BUT-type DED. The prevalence and severity of DED in late adolescent girls is comparable with adults. Adolescents with DED are underserved and we believe that DED is a hidden but potentially serious health problem for this age group. | Masahiko Ayaki Motoko Kawashima Miki Uchino Kazuo Tsubota Kazuno Negishi | 2018 | International Journal of Ophthalmology(English edition)2018，11，2： | 5 |

| 9 | Primary localized malignant biphasic mesothelioma of the liver in a patient with asbestosis显示文摘We report a case of primary localized malignant biphasic mesothelioma of the liver in a 66-year-old man associated with asbestosis. The tumor was detected as a hepatic nodule, 4 cm in diameter, in the right lobe (S8 segment) on CT scan. Histopathological examination demonstrated an intrahepatic tumor with central necrosis consisting of a papillary epithelioid pattern on the surface of the liver, microcystic (microglandular or adenomatoid) pattern mainly in the subcapsular area and sarcomatoid pattern intermingled with microcystic pattern in the major part of the hepatic nodular tumor. Tumor cells, especially of epithelioid type, showed distinct immunoreactivity for mesothelial markers (WT-1, calretinin, D2-40, CK5/6, mesothelin, thrombomodulin) and no immunoreactivity for epithelial (adenocarcinoma) markers (CEA, CD15, BerEP4, BG8, MOC31). P53 immunoreactivity was detected focally in papillary epithelioid tumor cells and extensively in microcystic and sarcomatoid components, suggesting that the papillary epithelioid mesothelioma arose on the surface of the liver, and tumor cells showing microcystic and sarcomatoid patterns invaded and grew into the liver. To date, this is the first case of primary localized malignant biphasic mesothelioma of the liver, since all three primary hepatic mesotheliomas reported so far were epithelioid type. | Motoko Sasaki Ichiro Araki Toshiaki Yasui Masaru Kinoshita Keita Itatsu Takayuki Nojima Yasuni Nakanuma | 2009 | World Journal of Gastroenterology2009，15，5： | 3 |
| 10 | Participation of peribiliary glands in biliary tract pathophysiologies显示文摘AIM:To investigate the roles of peribiliary glands around the bile ducts in the pathophysiology of the biliary tract.METHODS:The expression of fetal pancreatic markers,pancreatic duodenal homeobox factor 1(PDX1)and hairy and enhancer of split 1(HES1)and endodermal stem/progenitor(S/P)cell markers[CD44s,chemokine receptor type 4(CXCR4),SOX9 and epithelial cell adhesion molecule(EpCAM)]were examined immunohistochemically in 32 normal adult livers(autopsy livers)and 22 hepatolithiatic livers(surgically resected livers).The latter was characterized by the proliferation of the peribiliary glands.Immunohistochemistry was performed using formalin-fixed,paraffin-embedded tissue sections after deparaffinization.Although PDX1and HES1 were expressed in both the nucleus and cytoplasm of epithelial cells,only nuclear staining was evaluated.SOX9 was expressed in the nucleus,while CD44s,CXCR4 and EpCAM were expressed in the cell membranes.The frequency and extent of the expression of these molecules in the lining epithelia and peribiliary glands were evaluated semi-quantitatively based on the percentage of positive cells:0,1+(focal),2+(moderate)and 3+(extensive).RESULTS:In normal livers,PDX1 was infrequently expressed in the lining epithelia,but was frequently expressed in the peribiliary glands.In contrast,HES1was frequently expressed in the lining epithelia,but its expression in the peribiliary glands was focal,suggesting that the peribiliary glands retain the potential of differentiation toward the pancreas and the lining epithelia exhibit properties to inhibit such differentiation.This unique combination was also seen in hepatolithiatic livers.The expression of endodermal S/P cell markers varied in the peribiliary glands in normal livers:SOX9 and EpCAM were frequently expressed,CD44s infrequently,and CXCR4 almost not at all.The expression of these markers,particularly CD44s and CXCR4,increased in the peribiliary glands and lining epithelia in hepatolithiatic livers.This increased expression of endodermal S/P cell markers may be related to the increased production of intestinal and gastric mucin and also to the biliary neoplasia associated with the gastric and intestinal phenotypes reported in hepatolithiasis.CONCLUSION:The unique expression pattern of PDX1and HES1 and increased expression of endodermal S/P cell markers in the peribiliary glands may be involved in biliary pathophysiologies. | Saya Igarashi Yasunori Sato Xiang Shan Ren Kenichi Harada Motoko Sasaki Yasuni Nakanuma | 2013 | World Journal of Hepatology2013，5，8： | 3 |

| 14 | 多丽丝·莱辛获诺贝尔文学奖显示文摘莱辛是个多产的作家,作品题材广泛,形式不拘一格,其中既有写实作品,也有太空小说、探险故事,着力反映的则是当代生活及活跃于其中的各种观念;她笔下的人物形形色色,多是女性、精神病患者、畸形儿、老人、恐怖分子等'边缘人';她视野开阔,其作品受到前苏联的马克思主义、伊斯兰教的苏非派神秘主义和西方精神分析的影响;她对普通读者、同行作家和专业评论家都影响至深。莱辛的创作紧紧抓住'粗糙的、未完成的'现实生活,表面上平淡,却很难从总体上把握,稍不留神就与其中的精妙擦肩而过。这恰恰是其作品魅力所在,也因此对文学批评传统提出了挑战。莱辛独立不羁,代表作《金色笔记》被视为女性主义的《圣经》,然而即使是女性主义这样的标签也束缚不了作家的个性。得知多丽丝·莱辛获得诺贝尔奖,很多熟悉她的人的第一反应就是:她早该得奖了! | Motoko Rich Sarah Lyall 姜红 | 2007 | 英语文摘2007，0，12： | 2 |
| 15 | Phantom bite syndrome:Revelation from clinically focused review显示文摘Phantom bite syndrome(PBS),also called occlusal dysesthesia,is characterized by persistent non-verifiable occlusal discrepancies.Such erroneous and unshakable belief of a“wrong bite”might impel patients to visit multiple dental clinics to meet their requirements to their satisfaction.Subsequently,it takes a toll on their quality of life causing,career disruption,financial loss and suicidal thoughts.In general,patients with PBS are quite rare but distinguishable if ever encountered.Since Marbach reported the first two cases in 1976,there have been dozens of published cases regarding this phenomenon,but only a few original studies were conducted.Despite the lack of official classification and guidelines,many authors agreed on the existence of a PBS“consistent pattern”that clinicians should be made aware.Nevertheless,the treatment approach has been solely based on incomplete knowledge of etiology,in which none of the proposed theories are fully explained in all the available cases.In this review,we have discussed the critical role of enhancing dental professionals’awareness of this phenomenon and suggested a comprehensive approach for PBS,provided by a multidisciplinary team of dentists,psychiatrists and exclusive psychotherapists. | Trang Thi Huyen Tu Motoko Watanabe Gayatri Krishnakumar Nayanar Yojiro Umezaki Haruhiko Motomura Yusuke Sato Akira Toyofuku | 2021 | World Journal of Psychiatry2021，11，11： | 2 |
