| 1 | 悬吊技术在微血管减压术中的应用显示文摘BACKGROUND: The success of microvascular decompression (MVD) depends on the permanent and complete transposition of the offending vessels. This paper describes the stitched sling retraction techniques for treating trigeminal neuralgia (TN), hemifacial spasm (HFS), and glossopharyngeal neuralgia (GPN), focusing on the stitching point for slinging the offending artery in the appropriate direction. Between January 2007 and March 2009, 28 patients with TN, 5 patients with HFS, and 3 patients with GPN underwent MVD with a sling retraction technique. In cases of TN, MVD was performed using the infratentorial lateral supracerebellar approach, and the offending superior cerebellar artery was superomedially transposed with a sling stitched to the tentorium cerebelli. In cases of HFS, MVD was performed using the lateral suboccipital infrafloccular approach, and the offending vertebral artery was superolaterally transposed with a sling stitched to the petrous dura. In cases of GPN, MVD was performed using the transcondylar fossa approach, in which the posterior inferior cerebellar artery was inferolaterally mobilized with a sling secured to the jugular tubercle. No patient suffered recurrence in the follow-up period. For the sling retraction technique to be performed successfully, it is important for a stitch to be placed at a suitable site to sling the offending vessel in the intended direction. An appropriate surgical approach must be used to obtain a sufficient operative field for performing the stitching procedures safely. | Masuoka J Matsushima T Kawashima M Nakahara Y Funaki T Mineta T | 2011 | 中华神经外科疾病研究杂志2011，10，2： | 19 |
| 2 | Usefulness of bispectral monitoring of conscious sedation during endoscopic mucosal dissection显示文摘AIM: To assess the usefulness of bispectral index (BIS) monitoring in order to carry out endoscopic submucosal dissection (ESD) safely and with patients' satisfaction. METHODS: Three hundred sixty-six patients with an early-stage neoplasm of the digestive tract were enrolled. The BIS monitor (A-1050: Aspect medical systems/NIHON KOHDEN, Tokyo, Japan) was used. The appropriate sedative condition was set at 55 to 75 BIS levels (BIS value) during the endoscopic procedures. RESULTS: Among 366 cases, 13 were accompanied by adverse events during and/or after ESD. All episodes occurred in cases with BIS value between 56 and 65. Hypotension was observed in four cases, and bradycardia in six. Respiratory distress was observed in two cases with chronic pulmonary obstructive disease. All patients with adverse events were able to leave the hospital without extension of the hospitalization. CONCLUSION: BIS monitoring is useful to safely perform ESD. A BIS value of 70 to 75 is suitable for ESD. | Kazunori Hata Akira Andoh Kiyoyuki Hayafuji Atsuhiro Ogawa Tamio Nakahara Tomoyuki Tsujikawa Yoshihide Fujiyama Yasuharu Saito | 2009 | World Journal of Gastroenterology2009，15，5： | 9 |
| 3 | Diagnosis of early gastric cancer using narrow band imaging and acetic acid显示文摘AIM: To determine whether the endoscopic findings of depressed-type early gastric cancers(EGCs) could precisely predict the histological type.METHODS: Ninety depressed-type EGCs in 72 patients were macroscopically and histologically identified. We evaluated the microvascular(MV) and mucosal surface(MS) patterns of depressed-type EGCs using magnifying endoscopy(ME) with narrow-band imaging(NBI)(NBI-ME) and ME enhanced by 1.5% acetic acid, respectively. First, depressed-type EGCs were classified according to MV pattern by NBI-ME. Subsequently, EGCs unclassified by MV pattern were classified according to MS pattern by enhanced ME(EME) images obtained from the same angle.RESULTS: We classified the depressed-type EGCs into the following 2 MV patterns using NBI-ME: a fine-network pattern that indicated differentiated adenocarcinoma(25/25, 100%) and a corkscrew pattern that likely indicated undifferentiated adenocarcinoma(18/23, 78.3%). However, 42 of the 90(46.7%) lesions could not be classified into MV patterns by NBI-ME. These unclassified lesions were then evaluated for MS patterns using EME, which classified 33(81.0%) lesions as MS patterns, diagnosed as differentiated adenocarcinoma. As a result, 76 of the 90(84.4%) lesions were matched with histological diagnoses using a combination of NBI-ME and EME.CONCLUSION: A combination of NBI-ME and EME was useful in predicting the histological type of depressedtype EGC. | Ken Matsuo Hidetoshi Takedatsu Michita Mukasa Hiroaki Sumie Hikaru Yoshida Yasutomo Watanabe Jun Akiba Keita Nakahara Osamu Tsuruta Takuji Torimura | 2015 | World Journal of Gastroenterology2015，21，4： | 9 |
| 4 | Safety of hepatectomy for elderly patients with hepatocellular carcinoma显示文摘The number of elderly patients with hepatocellular carcinoma(HCC) has been increasing.Characteristics of elderly HCC patients are a higher proportion of females,a lower rate of positive hepatitis B surface antigen,and a higher rate of positive hepatitis C antibodies.Careful patient selection is vital for performing hepatectomy safely in elderly HCC patients.Treatment strategy should be decided by not only considering tumor stage and hepatic functional reserve,but also physiological status,including comorbid disease.Various assessment tools have been applied to predict the risk of hepatectomy.The reported mortality and morbidity rates after hepatectomy in elderly HCC patients ranged from 0% to 42.9% and from 9% to 51%,respectively.Overall survival rate after hepatectomy in elderly HCC patients at 5 years ranged from 26% to 75.9%.Both short-term and long-term results after hepatectomy for strictly selected elderly HCC patients are almost the same as those for younger patients.However,considering physiological characteristics and the high prevalence of comorbid disease in elderly patients,it is important to assess patients more meticulously and to select them strictly if scheduled to undergo major hepatectomy. | Koichi Oishi Toshiyuki Itamoto Toshihiko Kohashi Yasuhiro Matsugu Hideki Nakahara Mikiya Kitamoto | 2014 | World Journal of Gastroenterology2014，20，41： | 8 |
| 5 | Feasibility of gastric endoscopic submucosal dissection with continuous low-dose aspirin for patients receiving dual antiplatelet therapy显示文摘BACKGROUND Endoscopic submucosal dissection(ESD) for gastric neoplasms during continuous low-dose aspirin(LDA) administration is generally acceptable according to recent guidelines. This retrospective study aimed to investigate the effect of continuous LDA on the postoperative bleeding after gastric ESD in patients receiving dual antiplatelet therapy(DAPT).AIM To investigate the feasibility of gastric ESD with continuous LDA in patients with DAPT.METHODS A total of 597 patients with gastric neoplasms treated with ESD between January2010 and June 2017 were enrolled. The patients were categorized according to type of antiplatelet therapy(APT).RESULTS The postoperative bleeding rate was 6.9%(41/597) in all patients. Patients were divided into the following two groups: no APT(n = 443) and APT(n = 154). APT included single-LDA(n = 95) and DAPT(LDA plus clopidogrel, n = 59)subgroups. In the single-LDA and DAPT subgroups, 56 and 39 patients were received continuous LDA, respectively. The bleeding rate with continuous singleLDA(10.7%) was similar to that with discontinuous single-LDA(10.3%)(P >0.99). Although the bleeding rate with continuous LDA in patients receiving DAPT(23.1%) was higher than that with discontinuous LDA in patients receiving DAPT(5.0%), no significant difference was observed(P = 0.141).CONCLUSION The bleeding rate with continuous LDA in patients receiving DAPT was not statistically different from that with discontinuous LDA in patients receiving DAPT. Therefore, continuous LDA administration may be acceptable for ESD in patients receiving DAPT, although patients should be carefully monitored for possible bleeding. | Hideaki Harada Satoshi Suehiro Daisuke Murakami Ryotaro Nakahara Takuya Nagasaka Tetsuro Ujihara Ryota Sagami Yasushi Katsuyama Kenji Hayasaka Yuji Amano | 2019 | World Journal of Gastroenterology2019，25，4： | 6 |
| 6 | Endoscopic submucosal dissection for small submucosal tumors of the rectum compared with endoscopic submucosal resection with a ligation device显示文摘AIM To evaluate the efficacy and safety of endoscopic submucosal dissection(ESD) for small rectal submucosal tumors(SMTs).METHODS Between August 2008 and March 2016, 39 patients were treated with endoscopic submucosal resection with a ligation device(ESMR-L)(n = 21) or ESD(n = 18) for small rectal SMTs in this study. Twenty-five lesions were confirmed by histological evaluation of endoscopic biopsy prior to the procedure, and 14 lesions were not evaluated by endoscopic biopsy. The results for the ESMR-L group and the ESD group were retrospectively compared, including baseline characteristics and therapeutic outcomes.RESULTS The rate of en bloc resection was 100% in both groups. Although the rate of complete endoscopic resectionwas higher in the ESD group than in the ESMR-L group(100% vs 95.2%), there were no significant differences between the two groups(P = 0.462). In one patient in the ESMR-L group with a previously biopsied tumor, histological complete resection with a vertical margin involvement of carcinoid tumor could not be achieved, whereas there was no incomplete resection in the ESD group. The mean length of the procedure was significantly greater in the ESD group than in the ESMR-L group(14.7 ± 6.4 min vs 5.4 ± 1.7 min, P < 0.05). The mean period of the hospitalization was also significantly longer in the ESD group than in the ESMR-L group(3.7 ± 0.9 d vs 2.8 ± 1.5 d, P < 0.05). Postoperative bleeding was occurred in one patient in the ESMR-L group.CONCLUSION Both ESMR-L and ESD were effective for treatment of small rectal SMTs. ESMR-L was simpler to perform than ESD and took less time. | Hideaki Harada Satoshi Suehiro Daisuke Murakami Ryotaro Nakahara Takanori Shimizu Yasushi Katsuyama Yasunaga Miyama Kenji Hayasaka Shigetaka Tounou | 2017 | World Journal of Gastrointestinal Endoscopy2017，9，2： | 5 |
| 7 | Crowned dens syndrome developed after an endoscopic retrograde cholangiopancreatography procedure显示文摘We present a unique case of crowned dens syndrome(CDS) that developed after endoscopic retrograde cholangiopancreatography(ERCP) in a patient who presented with fever and neck pain. Administration of non-steroidal anti-inflammatory drugs was extremely effective for relieving fever and neck pain, and in the improvement of inflammatory markers. To the best of our knowledge, this is the first case report of CDS caused by an ERCP procedure. In a patient with fever and neck pain after an ERCP procedure, CDS should be considered in the differential diagnosis. | Hiroyasu Nakano Kazunari Nakahara Yosuke Michikawa Keigo Suetani Ryo Morita Nobuyuki Matsumoto Fumio Itoh | 2016 | World Journal of Gastroenterology2016，22，39： | 5 |
| 8 | 血管钙化:血管钙化与主要急性冠状动脉事件的演变关系显示文摘冠状动脉(简称冠脉)钙化是冠脉粥样硬化的明确证据。Agatston评分反映钙化程度和密度,其与患者发生主要急性冠脉事件的风险密切相关。动脉粥样硬化发生后,内皮细胞受损,低密度脂蛋白胆固醇(LDLc)渗透至管壁内膜下,内膜下胶原蛋白中的蛋白聚糖对LDLc具有高亲和力,将脂蛋白胆固醇复合物滞留其中。随着内皮损伤的修复,LDLc被捕获至内膜下,滞留的LDLc诱导上覆内皮的炎性反应,使内皮表达趋化肽,趋化肽吸引血液中的单核细胞,使单核细胞沿浓度梯度进入组织,成为巨噬细胞,巨噬细胞吞噬并消化动脉粥样硬化中刺激性的LDLc。在消化LDLc的过程中,巨噬细胞中的酶使LDLc复合物氧化,氧化的低密度脂蛋白(LDL)对巨噬细胞产生毒性,当其数量充足时,可导致巨噬细胞死亡,促进动脉粥样硬化的炎性反应。在坏死性炎性病灶中,调控组织中钙、磷浓度的机制失调,使得磷酸钙的溶度积过高,从而产生微小的磷酸钙晶体。随着炎性反应的持续存在,更多的磷酸钙晶体形成并聚集。当这些聚集的磷酸钙晶体超过1 mm时,就成为临床CT可识别的冠脉钙化。连续的门控心脏CT扫描证实,一旦形成CT可见的钙化,其大小不会明显减少,但可能会增加。 | H.William Strauss Takehiro Nakahara Navneet Narula Jagat Narula 俞雯吉(译) 王跃涛(审校 | 2021 | 中华核医学与分子影像杂志2021，41，12： | 4 |
| 9 | Need for pancreatic stenting after sphincterotomy in patients with difficult cannulation显示文摘AIM:To investigate the need for pancreatic stenting after endoscopic sphincterotomy(EST)in patients with difficult biliary cannulation.METHODS:Between April 2008 and August 2013,2136 patients underwent endoscopic retrograde cholangiopancreatography(ERCP)-related procedures.Among them,55 patients with difficult biliary cannulation who underwent EST after bile duct cannulation using the pancreatic duct guidewire placement method(P-GW)were divided into two groups:a stent group(n=24;pancreatic stent placed)and a no-stent group(n=31;no pancreatic stenting).We retrospectively compared the two groups to examine the need for pancreatic stenting to prevent post-ERCP pancreatitis(PEP)in patients undergoing EST after biliary cannulation by P-GW.RESULTS:No differences in patient characteristics or endoscopic procedures were observed between the two groups.The incidence of PEP was 4.2%(1/24)and29.0%(9/31)in the Stent and no-stent groups,respectively,with the no-stent group having a significantly higher incidence(P=0.031).The PEP severity was mild for all the patients in the stent group.In contrast,8 had mild PEP and 1 had moderate PEP in the no-stent group.The mean serum amylase levels(means±SD)3 h after ERCP(183.1±136.7 vs 463.6±510.4 IU/L,P=0.006)and on the day after ERCP(209.5±208.7vs 684.4±759.3 IU/L,P=0.002)were significantly higher in the no-stent group.A multivariate analysis identified the absence of pancreatic stenting(P=0.045;odds ratio,9.7;95%CI:1.1-90)as a significant risk factor for PEP.CONCLUSION:In patients with difficult cannulation in whom the bile duct is cannulated using P-GW,a pancreatic stent should be placed even if EST has been performed. | Kazunari Nakahara Chiaki Okuse Keigo Suetani Yosuke Michikawa Shinjiro Kobayashi Takehito Otsubo Fumio Itoh | 2014 | World Journal of Gastroenterology2014，20，26： | 4 |
| 10 | Thrombomodulin in the management of acute cholangitisinduced disseminated intravascular coagulation显示文摘AIM: To evaluate the need for thrombomodulin(r TM) therapy for disseminated intravascular coagulation(DIC) in patients with acute cholangitis(AC)-induced DIC. METHODS: Sixty-six patients who were diagnosedwith AC-induced DIC and who were treated at our hospital were enrolled in this study. The diagnoses of AC and DIC were made based on the 2013 Tokyo Guidelines and the DIC diagnostic criteria as defined by the Japanese Association for Acute Medicine, respectively. Thirty consecutive patients who were treated with r TM between April 2010 and September 2013(r TM group) were compared to 36 patients who were treated without r TM(before the introduction of r TM therapy at our hospital) between January 2005 and January 2010(control group). The two groups were compared in terms of patient characteristics at the time of DIC diagnosis(including age, sex, primary disease, severity of cholangitis, DIC score, biliary drainage, and anti-DIC drugs), the DIC resolution rate, DIC score, the systemic inflammatory response syndrome(SIRS) score, hematological values, and outcomes. Using logistic regression analysis based on multivariate analyses, we also examined factors that contributed to persistent DIC. RESULTS: There were no differences between the r TM group and the control group in terms of the patients' backgrounds other than administration. DIC resolution rates on day 9 were higher in the r TM group than in the control group(83.3% vs 52.8%, P < 0.01). The mean DIC scores on day 7 were lower in the r TM group than in the control group(2.1 ± 2.1 vs 3.5 ± 2.3, P = 0.02). The mean SIRS scores on day 3 were significantly lower in the r TM group than in the control group(1.1 ± 1.1 vs 1.8 ± 1.1, P = 0.03). Mortality on day 28 was 13.3% in the r TM group and 27.8% in the control group; these rates were not significantly different(P = 0.26). Multivariate analysis identified only the absence of biliary drainage as significantly associated with persistent DIC(P < 0.01, OR = 12, 95%CI: 2.3-60). Although the difference did not reach statistical significance, primary diseases(malignancies)(P = 0.055, OR = 3.9, 95%CI: 0.97-16) and the non-use of r TM had a tendency to be associated with persistent DIC(P = 0.08, OR = 4.3, 95%CI: 0.84-22).CONCLUSION: The add-on effects of r TM are anticipated in the treatment of AC-induced DIC, although biliary drainage for AC remains crucial. | Keigo Suetani Chiaki Okuse Kazunari Nakahara Yosuke Michikawa Yohei Noguchi Midori Suzuki Ryo Morita Nozomi Sato Masaki Kato Fumio Itoh | 2015 | World Journal of Gastroenterology2015，21，2： | 4 |
| 11 | Histological changes at an endosonography-guided biliary drainage site:A case report显示文摘Endosonography-guided biliary drainage (ESBD) is a new method enabling internal drainage of an obstructed bile duct. However,the histological conditions associated with fistula development via the duodenum to the bile duct have not been reported. We performed ESBD 14 d preoperatively in a patient with an ampullary carcinoma and histologically confirmed changes in and around the fistula. The female patient developed no complications relevant to ESBD. Levels of serum bilirubin and hepatobiliary enzymes declined quickly,and pancreatoduodenectomy was carried out uneventfully. The resected specimen was sliced and stained with hematoxylin-eosin. Histological evaluation of the puncture site in the duodenum and bile-duct wall,and the sinus tract revealed no hematoma,bile leakage,or abscess in or around the sinus tract. Little sign of granulation,fibrosis,and inflammatory cell infiltration was observed. Although further large-scale confirmatory studies are needed,the findings here may encourage more active use of ESBD as a substitute for percutaneous transhepatic drainage in cases with failed/difficult endoscopic biliary stenting. | Naotaka Fujita Yutaka Noda Go Kobayashi Kei Ito Takashi Obana Jun Horaguchi Osamu Takasawa Kazunari Nakahara | 2007 | World Journal of Gastroenterology2007，13，41： | 4 |
| 12 | Study on the optical property and biocompatibility of a tissue engineering cornea显示文摘AIM: To study the optical property and biocompatibility of a tissue engineering cornea.METHODS: The cross-linker of N-(3-Dimethylaminoropyl)-N'ethylcarbodiimide hydrochloride(EDC)/ N-Hydroxysuccin- imide (NHS) was mixed with Type I collagen at 10% (weight/volume). The final solution was molded to the shape of a corneal contact lens. The collagen concentrations of 10%, 12.5%, 15%, 17.5% and 20% artificial corneas were tested by UV/vis-spectroscopy for their transparency compared with normal rat cornea. 10-0 sutures were knotted on the edges of substitute to measure the corneal buttons's mechanical properties. Normal rat corneal tissue primary culture on the collagen scaffold was observed in 4 weeks. Histopathologic examinations were performed after 4 weeks of in vitro culturing.RESULTS: The collagen scaffold appearance was similar to that of soft contact lens. With the increase of collagen concentration, the transparency of artificial corneal buttons was diminished, but the toughness of the scaffold was enhanced. The scaffold transparency in the 10% concentration collagen group resembled normal rat cornea. To knot and embed the scaffold under the microscope, 20% concentration collagen group was more effective during implantation than lower concentrations of collagen group. In the first 3 weeks, corneal cell proliferation was highly active. The shapes of cells that grew on the substitute had no significant difference when compared with the cells before they were moved to the scaffold. However, on the fortieth day, most cells detached from the scaffold and died. Histopathologic examination of the primary culture scaffold revealed well grown corneal cells tightly attached to the scaffold in the former culturing. CONCLUSION: Collagen scaffold can be molded to the shape of soft contact corneal lens with NHS/EDC. The biological stability and biocompatibility of collagen from animal species may be used as material in preparing to engineer artificial corneal scaffold. | Yukiko Nakahara Dwight Xuan | 2012 | International Journal of Ophthalmology(English edition)2012，5，1： | 3 |
| 13 | Impact of lipoprotein lipase gene polymorphisms on ulcerative colitis显示文摘AIM: To examine the influence of lipoprotein lipase (LPL) gene polymorphism in ulcerative colitis (UC) patients. METHODS: Peripheral blood was obtained from 131 pa- tients with UC and 106 healthy controls for DNA extrac- tion. We determined LPL gene polymorphisms affecting the enzyme at Ser447stop, as well as HindⅢ and Pvu Ⅱ polymorphisms using PCR techniques. PCR products were characterized by PCR-RFLP and direct sequencing. Polymorphisms were examined for association with clini- cal features in UC patients. Genotype frequencies for LPL polymorphisms were also compared between UC patients and controls. RESULTS: In patients with onset at age 20 years or younger, C/G and G/G genotypes for Ser447stop poly- morphism were more prevalent than C/C genotype (OR = 3.13, 95% CI = 0.95-10.33). Patients with H+/- or H-/-genotype for HindⅢ polymorphism also were more nu- merous than those with H+/+ genotype (OR = 2.51, 95% CI = 0.85-7.45). In the group with H+/+ genotype for HindⅢ polymorphism, more patients had serum triglyc- eride concentrations over 150 mg/dL than patients with H+/- or H-/- genotype (P < 0.01, OR = 6.46, 95% CI = 1.39-30.12). Hypertriglycemia was also more prevalent in patients with P+/+ genotypes for PvuⅡ polymorphism (P < 0.05, OR = 3.0, 95% CI = 1.06-8.50). Genotype fre- quency for LPL polymorphism did not differ significantly between UC patients and controls. CONCLUSION: Ser447stop and HindⅢ LPL polymor- phisms may influence age of onset of UC, while HindⅢ and PvuⅡ polymorphisms influence serum triglyceride in UC patients. | Toshihito Kosaka Junji Yoshino Kazuo Inui Takao Wakabayashi Kazumu Okushima Takashi Kobayashi Hironao Miyoshi Yuta Nakamura Shigekazu Hayashi Taizou Shiraishi Masatoshi Watanabe Takayuki Yamamoto Ai Nakahara Takahiko Katoh | 2006 | World Journal of Gastroenterology2006，12，39： | 3 |
| 14 | Percutaneous endoscopic gastrostomy under steadypressure automatically controlled endoscopy:First clinicalseries显示文摘AIM: To elucidate the safety of percutaneous endoscopic gastrostomy(PEG) under steady pressure automatically controlled endoscopy(SPACE) using carbon dioxide(CO_2).METHODS: Nine patients underwent PEG with a modified introducer method under conscious sedation. A T-tube was attached to the channel of an endoscope connected to an automatic surgical insufflator. The stomach was inflated under the SPACE system. The intragastric pressure was kept between 4-8 mmH g with a flow of CO_2 at 35 L/min. Median procedure time, intragastric pressure, median systolic blood pressure, partial pressure of CO_2, abdominal girth before and immediately after PEG, and free gas and small intestinal gas on abdominal X-ray before and after PEG were recorded. RESULTS: PEG was completed under stable pneumostomach in all patients, with a median procedural time of 22 min. Median intragastric pressure was 6.9 mmH g and median arterial CO_2 pressure before and after PEG was 42.1 and 45.5 Torr(NS). The median abdominal girth before and after PEG was 68.1 and 69.6 cm(NS). A mild free gas image after PEG was observed in two patients, and faint abdominal gas in the downstream bowel was documented in two patients.CONCLUSION: SPACE might enable standardized pneumostomach and modified introducer procedure of PEG. | Hiroyuki Imaeda Kiyokazu Nakajima Naoki Hosoe Masanori Nakahara Shinichiro Zushi Motohiko Kato Kazuhiro Kashiwagi Yasushi Matsumoto Kayoko Kimura Rieko Nakamura Norihito Wada Masahiko Tsujii Naohisa Yahagi Toshifumi Hibi Takanori Kanai Tetsuo Takehara Haruhiko Ogata | 2016 | World Journal of Gastrointestinal Endoscopy2016，8，3： | 2 |
| 15 | Primary biliary cholangitis metachronously complicated with combined hepatocellular carcinoma-cholangiocellular carcinoma and hepatocellular carcinoma显示文摘Primary biliary cholangitis(PBC) is a progressive cholestatic liver disease characterized by the presence of highly specific antimitochondrial antibodies, portal inflammation and lymphocyte-dominated destruction of the intrahepatic bile ducts, which leads to cirrhosis. While its pathogenesis remains unclear, PBC that shows histological progression to fibrosis carries a high risk of carcinogenesis; the same is true of viral liver diseases. In patients with PBC, the development of hepatocellular carcinoma(HCC) is rare; the development of combined hepatocellular carcinoma and cholangiocellular carcinoma(c HCC-CCC) is extraordinary. Herein, we report a rare case of PBC metachronously complicated by c HCC-CCC and HCC, which, to the best of our knowledge, has never been reported. We present a case report of a 74-year-old Japanese woman who was diagnosed as PBC in her 40's by using blood tests and was admitted to our department for further management of an asymptomatic liver mass. She had a tumor of 15 mm in size in segment 8 of the liver and underwent a partial resection of the liver. Subsequent pathological findings resulted in the diagnosis of c HCC-CCC, arising from stage 3 PBC. One year after the initial hepatectomy, a second tumor of 10 mm in diameter was found in segment 5 of the liver; a partial resection of the liver was performed. Subsequent pathological findings led to HCC diagnosis. The component of HCC in the initial tumor displayed a trabecular growth pattern while the second HCC showed a pseudoglandular growth pattern, suggesting that metachronous tumors that arise from PBC are multicentric. | Ryuta Ide Akihiko Oshita Takashi Nishisaka Hideki Nakahara Shiomi Aimitsu Toshiyuki Itamoto | 2017 | World Journal of Hepatology2017，9，36： | 2 |
| 16 | Human pluripotent stem cells:Towards therapeutic development for the treatment of lifestyle diseases显示文摘There are two types of human pluripotent stem cells: Embryonic stem cells(ESCs) and induced pluripotent stem cells(iPSCs),both of which launched themselves on clinical trials after having taken measures to overcome problems: Blocking rejections by immunosuppressants regarding ESCs and minimizing the risk of tumorigenicity by depleting exogenous gene components regarding iP SCs.It is generally assumed that clinical applications of human pluripotent stem cells should be limited to those cases where there are no alternative measures for treatments because of the risk in transplanting those cells to living bodies.Regarding lifestyle diseases,we have already several therapeutic options,and thus,development of human pluripotent stem cell-based therapeutics tends to be avoided.Nevertheless,human pluripotent stem cells can contribute to the development of new therapeutics in this field.As we will show,there is a case where only a short-term presence of human pluripotent stem-derived cells can exert long-term therapeutic effects even after they are rejected.In those cases,immunologically rejections of ESC-or allogenic iP SC-derived cells may produce beneficial outcomes by nullifying the risk of tumorigenesis without deterioration of therapeutic effects.Another utility of human pluripotent stem cells is the provision of an innovative tool for drug discovery that are otherwise unavailable.For example,clinical specimens of human classical brown adipocytes(BAs),which has been attracting a great deal of attention as a new target of drug discovery for the treatment of metabolic disorders,are unobtainable from living individuals due to scarcity,fragility and ethical problems.However,BA can easily be produced from human pluripotent stem cells.In this review,we will contemplate potential contribution of human pluripotent stem cells to therapeutic development for lifestyle diseases. | Miwako Nishio Masako Nakahara Akira Yuo Kumiko Saeki | 2016 | World Journal of Stem Cells2016，8，2： | 2 |
