1外周神经母细胞性肿瘤临床病理特点显示文摘外周神经母细胞性肿瘤(peripheralneuroblastictumors,pNT)由神经母细胞瘤(neuroblastoma)、节细胞性神经母细胞瘤(ganglioneuroblastoma,GNB)和节细胞神经瘤(ganglioneuroma,GN)组成,是起源于交感神经系统的胚胎性肿瘤,也是儿童最常见的颅外恶性实体瘤。据报道,美国每年新增pNT诊断病例约有650例,病死率占儿童恶性肿瘤的15%。pNT的临床生物学行为具有高度异质性,预后取决于患儿诊断时的年龄、临床分期、组织学类型以及特异性遗传学异常情况。Larry Wang 何乐健 Hiroyuki Shimada 2012中华病理学杂志2012,41,4:13
2Effects of lysedEnterococcus faecalis FK-23 on experimental allergic rhinitis in a murine model显示文摘In the current study,we sought to investigate whether lysed Enterococcus faecalis FK-23(LFK),a heat-killed probiotic preparation,attenuated eosinophil influx into the upper airway and had immunomodulatory activity in a murine allergic rhinitis model.Eighteen BALB/c mice were divided into three groups;the ovalbumin(OVA)-sensitized/challenged group,which received saline orally for 6 weeks(OVA group),the OVA-sensitized/challenged group,which received LFK orally for 6 weeks(LFK-fed group),and the non-sensitized group,which received saline for 6 weeks(saline control group).Nasal rubbing and sneezing were monitored during the study.After the final challenge,interleukin(IL)-4,interferon(IFN)-γ,and OVA-specific IgE levels in the sera and splenocyte culture supernatants were determined,eosinophilic infiltrate into the upper airway was quantified,and splenic CD4+CD25+ regulatory T cells(Tregs) were examined by flow cytometry.We found that nasal rubbing was significantly reduced in LFK-fed mice compared to the OVA group on d 27 and 35,and sneezing was significantly inhibited by LFK administration for 35 d.LFK-fed mice had significantly less eosinophil influx into the nasal mucosa than the OVA group.There were no significant differences between the LFK-fed group and OVA group in the serum and splenocyte culture supernatant levels of IL-4,IFN-γ,and OVA-specific IgE.Interestingly,the LFK-fed mice had a significantly greater percentage of splenic CD4+CD25+ Tregs than OVA group.Our results indicate that oral administration of LFK may alleviate nasal symptoms,reduce nasal eosinophilia,and increase the percentage of CD4+CD25+ Tregs in experimental allergic rhinitis.Luping Zhu Takashi Shimada Ruoxi Chen Meiping Lu Qingzhao Zhang Wenmin Lu Min Yin Tadao Enomoto Lei Cheng 2012The Journal of Biomedical Research2012,26,3:11
3Systematic review of laparoscopic vs open surgery for colorectal cancer in elderly patients显示文摘AIM: To verify the safety and validity of laparoscopic surgery for the treatment of colorectal cancer in elderly patients.METHODS: A meta-analysis was performed of a systematic search of studies on an electronic database. Studies that compared laparoscopic colectomy(LAC) in elderly colorectal cancer patients with open colectomy(OC) were retrieved, and their short and long-term outcomes compared. Elderly people were defined as 65 years old or more. Inclusion criteria were set at: Resection of colorectal cancer, comparison between laparoscopic and OC and no significant difference in backgrounds between groups.RESULTS: Fifteen studies were identified for analysis. LAC was performed on 1436 patients, and OC performed on 1810 patients. In analyses of short-term outcomes, operation time for LAC was longer than for OC(mean difference = 34.4162, 95%CI: 17.8473-50.9851, P < 0.0001). The following clinical parameters were lower in LAC than in OC: Amount of estimated blood loss(mean difference =-93.3738, 95%CI:-132.3437 to-54.4039, P < 0.0001), overall morbidity(OR = 0.5427, 95%CI: 0.4425-0.6655, P < 0.0001), incisional surgical site infection(OR = 0.6262, 95%CI: 0.4310-0.9097, P = 0.0140), bowel obstruction and ileus(OR = 0.6248, 95%CI: 0.4519-0.8638, P = 0.0044) and cardiovascular complications(OR = 0.4767, 95%CI: 0.2805-0.8101, P = 0.0062). In analyses of long-term outcomes(median follow-up period: 36.4 mo in LAC, 34.3 mo in OC), there was no significant difference in overall survival(mean difference = 0.8321, 95%CI: 0.5331-1.2990, P = 0.4187) and disease specific survival(mean difference = 1.0254, 95%CI: 0.6707-1.5675, P = 0.9209). There was also no significant difference in the number of dissected lymph nodes(mean difference =-0.1360, 95%CI:-4.0553-3.7833, P = 0.9458).CONCLUSION: LAC in elderly colorectal cancer patients had benefits in short-term outcomes compared with OC except operation time. The long-term outcomes and oncological clearance of LAC were similar to that of OC. These results support the assertion that LAC is an effective procedure for elderly patients with colorectal cancer.Shoichi Fujii Mitsuo Tsukamoto Yoshihisa Fukushima Ryu Shimada Koichi Okamoto Takeshi Tsuchiya Keijiro Nozawa Keiji Matsuda Yojiro Hashiguchi 2016World Journal of Gastrointestinal Oncology2016,8,7:10
4Acute appendicitis following endoscopic mucosal resection of cecal adenoma显示文摘Endoscopic mucosal resection(EMR) allows the removal of flat or sessile lesions, laterally spreading tumors, and carcinoma of the colon or the rectum limited to the mucosa or the superficial submucosa. Acute appendicitis is the most common abdominal emergency requiring emergency surgery, and it is also a rare complication of diagnostic colonoscopy and therapeutic endoscopy, including EMR. In the case presented here, a 53-year-old female underwent colonoscopy due to a positive fecal occult blood test and was diagnosed with cecal adenoma. She was referred to our hospital and admitted for treatment. The patient had no other symptoms. EMR was performed, and 7 h after the surgery, the patient experienced right-lower abdominal pain. Laboratory tests performed the following day revealed a WBC count of 16000/mm3, a neutrophil count of 14144/mm3, and a C-reactive protein level of 2.20 mg/d L, indicating an inflammatory response. Computed tomography also revealed appendiceal wall thickening and swelling, so acute appendicitis following EMR was diagnosed. Antibiotics were initiated leading to total resolution of the symptoms, and the patient was discharged on the sixth post-operative day. Pathological analysis revealed a high-grade cecal tubular adenoma. Such acute appendicitis following EMR is extremely rare, and EMR of the cecum may be a rare cause of acute appendicitis.Yukako Nemoto Junya Tokuhisa Nagasato Shimada Tatsuya Gomi Iruru Maetani 2015World Journal of Gastroenterology2015,21,27:9
5病理性近视患者视乳头周围脱离的特征显示文摘目的:在一组高度近视患者中,评估新近认识的视乳头周围病变。即病理性近视视乳头周围脱离(PD-PM)的患病率和临床特征。 方法:共纳入324位高度近视患者(632只眼)。在这些患者中观察PDPMD的发病率、病变范围、荧光素和吲哚青绿造影检查结果及OCT结果。并对有PDPM的患者进行视野检查(Goldmann动态视野检查法和Humphrey 30-2程序)。结果:632只高度近视眼中有31只眼(4.9%)存在视乳头周围脱离。PDPM病变部位的OCT扫描显示视神经邻近部位视网膜色素上皮层的局限性脱离。PDPM常位于视盘下方。但一些患者的病变几乎环绕整个视盘。邻近PDPM的下方近视弧形斑有陡峭的凹陷。且颞下视网膜静脉在跨过PDPM和凹陷的近视弧形斑时明显弯曲。PDPM眼常被检出存在青光眼性视野缺损(71.0%)。 结论:本研究表明PDPM在高度近视眼中并非罕见。虽然其发病机制和病理学意义尚需进一步分类。高度近视PDPM的出现提示可能存在视野缺损。Noriaki Shimada Kyoko Ohno-Matsui Takeshi Yoshida Kenjiro Yasuzumi Ariko Kojima Kanako Kobayashi Soh Futagami Takashi Tokoro Manabu Mochizuki 刘亮(译) 2006美国医学会眼科杂志(中文版)2006,18,4:9

8Recent advances in ultrasonic-assisted machining for the fabrication of micro/nano-textured surfaces显示文摘Shaolin XU Tsunemoto KURIYAGAWA Keita SHIMADA Masayoshi MIZUTANI 2017Frontiers of Mechanical Engineering2017,12,1:7
9Analysis of Machinable Structures and Their Wettability of Rotary Ultrasonic Texturing Method显示文摘Tailored surface textures at the micro- or nanoscale dimensions are widely used to get required functional performances.Rotary ultrasonic texturing(RUT) technique has been proved to be capable of fabricating periodic micro- and nanostructures. In the present study, diamond tools with geometrically defined cutting edges were designed for fabricating different types of tailored surface textures using the RUT method. Surface generation mechanisms and machinable structures of the RUT process are analyzed and simulated with a 3D-CAD program. Textured surfaces generated by using a triangular pyramid cutting tip are constructed. Different textural patterns from several micrometers to several tens of micrometers with few burrs were successfully fabricated, which proved that tools with a proper two-rake-face design are capable of removing cutting chips efficiently along a sinusoidal cutting locus in the RUT process. Technical applications of the textured surfaces are also discussed. Wetting properties of textured aluminum surfaces were evaluated by combining the test of surface roughness features. The results show that the real surface area of the textured aluminum surfaces almost doubled by comparing with that of a flat surface, and anisotropic wetting properties were obtained due to the obvious directional textural features.XU Shaolin SHIMADA Keita MIZUTANI Masayoshi KURIYAGAWA Tsunemoto 2016Chinese Journal of Mechanical Engineering2016,29,6:6
10Significance of functional hepatic resection rate calculated using 3D CT/^(99m)Tc-galactosyl human serum albumin singlephoton emission computed tomography fusion imaging显示文摘AIM: To evaluate the usefulness of the functional hepatic resection rate(FHRR) calculated using 3D computed tomography(CT)/^(99m)Tc-galactosyl-human serum albumin(GSA) single-photon emission computed tomography(SPECT) fusion imaging for surgical decision making. METHODS: We enrolled 57 patients who underwent bi- or trisectionectomy at our institution between October 2013 and March 2015. Of these, 26 patients presented with hepatocellular carcinoma, 12 with hilar cholangiocarcinoma, six with intrahepatic cholangiocarcinoma, four with liver metastasis, and nine with other diseases. All patients preoperatively underwent three-phase dynamic multidetector CT and ^(99m)Tc-GSA scintigraphy. We compared the parenchymal hepatic resection rate(PHRR) with the FHRR, which was defined as the resection volume counts per total liver volume counts on 3D CT/^(99m)Tc-GSA SPECT fusion images.RESULTS: In total, 50 patients underwent bisectionectomy and seven underwent trisectionectomy.Biliary reconstruction was performed in 15 patients, including hepatopancreatoduodenectomy in two. FHRR and PHRR were 38.6 ± 19.9 and 44.5 ± 16.0, respectively; FHRR was strongly correlated with PHRR. The regression coefficient for FHRR on PHRR was 1.16(P < 0.0001). The ratio of FHRR to PHRR for patients with preoperative therapies(transcatheter arterial chemoembolization, radiation, radiofrequency ablation, etc.), large tumors with a volume of > 1000 m L, and/or macroscopic vascular invasion was significantly smaller than that for patients without these factors(0.73 ± 0.19 vs 0.82 ± 0.18, P < 0.05). Postoperative hyperbilirubinemia was observed in six patients. Major morbidities(Clavien-Dindo grade ≥ 3) occurred in 17 patients(29.8%). There was no case of surgeryrelated death.CONCLUSION: Our results suggest that FHRR is an important deciding factor for major hepatectomy, because FHRR and PHRR may be discrepant owing to insufficient hepatic inflow and congestion in patients with preoperative therapies, macroscopic vascular invasion, and/or a tumor volume of > 1000 m L.Yosuke Tsuruga Toshiya Kamiyama Hirofumi Kamachi Shingo Shimada Kenji Wakayama Tatsuya Orimo Tatsuhiko Kakisaka Hideki Yokoo Akinobu Taketomi 2016World Journal of Gastroenterology2016,22,17:6
11Evaluating 3D position and velocity of subject in parabolic flight experiment by use of the binocular stereo vision measurement显示文摘A practical method for evaluating the three-dimensional(3D) position and velocity of a moving object used in the parabolic flight experiment is developed by using the binocular stereo vision measurement theory. The camera calibration mathematic model without considering the lens distortion is introduced.The direct linear transformation(DLT) algorithm is improved to accomplish the camera calibration.The camera calibration result and optimization algorithm are used to calculate the object's world coordinate from image coordinate.The 3D position and the velocity of the moving object are obtained.The standard uncertainty in estimating the velocity is 0.0024 m/s,which corresponds to 1%level of the velocity of the object in the experiment.The results show that this method is very useful for the parabolic flight experiments.金涛 贾宏志 侯文玫 Ryo Yamamoto Norihiro Nagai Yusaku Fujii Koichi Maru Naoya Ohta Kazuhito Shimada 2010Chinese Optics Letters2010,8,6:6
12Role of hepatectomy for recurrent or initially unresectable hepatocellular carcinoma显示文摘As a result of donor shortage and high postoperative morbidity and mortality after liver transplantation,hepatectomy is the most widely applicable and reliable option for curative treatment of hepatocellular carcinoma(HCC).Because intrahepatic tumor recurrence is frequent after loco-regional therapy,repeated treatments are advocated provided background liver function is maintained.Among treatments including local ablation and transarterial chemoembolization,hepatectomy provides the best long-term outcomes,but studies comparing hepatectomy with other nonsurgical treatments require careful review for selection bias.In patients with initially unresectable HCC,transarterial chemo-or radio-embolization,and/or systemic chemotherapy can down-stage the tumor and conversion to resectable HCC is achieved in approximately 20%of patients.However,complete response is rare,and salvage hepatectomy is essential to help prolong patients’survival.To counter the short recurrence-free survival,excellent overall survival is obtained by combining and repeating different treatments.It is important to recognize hepatectomy as a complement,rather than a contraindication,to other nonsurgical treatments in a mul-tidisciplinary approach for patients with HCC,including recurrent or unresectable tumors.Yoji Kishi Kazuaki Shimada Satoshi Nara Minoru Esaki Tomoo Kosuge 2014World Journal of Hepatology2014,6,12:5

14Derivatization in Liquid Chromatography/Mass Spectrometric Analysis of Neurosteroids显示文摘Liquid chromatography/mass spectrometry (LC/MS) is now considered to be the most promising analytical method for the determination of biological substances, especially nonvolatile or highly polar substances However, some compounds do not show enough sensitivity in LC/MS and soft ionization methods commonly used in LC/MS, such as electrospray ionization (ESI) and atmospheric pressure chemical ionization (APCI), sometimes do not give satisfactory structural information This report presents an overview of the derivatization methods in the LC/MS analysis of neurosteroids or neuroactive neurosteroids, which are synthesized and accumulated in the nervous system The derivatization of pregnenolone 3 sulfate, one of these steroids, with 4 ( N,N dimethylaminosulfonyl) 7 hydrazino 2,1,3 benzoxadiazole gave a satisfactory sensitivity during the quantitative analysis using LC/ESI MS The obtained results are much lower than those previously obtained using gas chromatography/mass spectrometry or radioimmunoassay On the other hand, the derivatization to acetate was useful for the treatment of labile catechol estrogens in rat brains and gave enough structural information in LC/APCI MS, which confirmed the existence of catechol estrogens in mammalianKuniko MITAMURA, Kazutake SHIMADA (Faculty of Pharmaceutical Sciences, Kanazawa University 13 1, Takara machi, Kanazawa 920 0934, Japan) 2001色谱2001,19,6:5
