The purpose of our study was to retrospectively evaluate the clinical efficacy and safety of laparoscopy assisted distal gastrectomy (LADG) performed by one operating and advising surgeon in patients with gastric cancer over a period of 10 years. We examined the choice of anastomosis techniques, and compared the duration of surgery, blood loss, number of dissected lymph nodes and intraoperative complications for LADG and open distal gastrectomy (ODG). We studied 254 patients who underwent laparoscopic gastrectomy and 36 patients who underwent ODG. 169 of 254 patients received LADG. Duration of surgery was significantly longer for LADG than that for ODG, blood loss was significantly smaller, and numbers of dissected lymph nodes were similar. With LADG, there was anastomotic leakage in 2 patients and postoperative obstruction in 2 patients. No recurrence of disease and no deaths have been reported to date. Though previous clinical trials have shown that LADG is less invasive, our study of LADG in the real world did not show superiority, but rather equivalence to ODG in terms of other outcomes. This study could be advantageous to evaluate the clinical efficacy and safety of LADG without having to take into account multiple surgeons’ technical levels and the background differences between the facilities.

Early Pulsed Dye Laser Treatment for Infantile Hemangiomas: An Open Study for 50 Japanese Infancies

引用

Journal of Cosmetics, Dermatological Sciences and Applications 2013年第3期3卷 216-221页

作者： Hideki endo naoki Oiso Akira Kawada Department of Dermatology Kinki University Faculty of Medicine Osaka-Sayama Japan Department of Dermatology Kinki University Faculty of Medicine Osaka-Sayama Japan.

Infantile hemangiomas, occurring at birth or during the first weeks of life, are benign vascular tumors with an initial proliferative phase and a later involutional phase. The massive proliferation on the key regions and unpredicted regression may threaten?life. Thus, early management of infantile hemangiomas is necessary for affected infancies. Recent studies showed that propranolol for infantile hemangiomas had high efficacy for disappearance or reduction of infantile hemangiomas. However, a most recent study demonstrated existence of propranolol-resistant infantile hemangiomas. Therefore, we retrospectively evaluated efficacy of established early pulsed dye laser treatment for infantile hemangiomas in the 50 Japanese infancies which were applied in the period from 2000 to 2005, because our series included from the plaque subtype to the more proliferative tumor subtype. High efficacy in both subtypes suggests that early pulsed dye laser treatment can still be included as the first option for the mixed type of infantile hemangiomas and that pulsed dye laser treatment may be useful as the second line for the propranolol-resistant mixed type of infantile hemangiomas.

Luminescence of Eu ^(3+) in LnAlO_3 (Ln=Gd,Y) under UV and VUV Excitation

引用

Journal of Rare Earths 2004年第1期22卷 95-99页

作者：王育华 endo Tadshi 李峰 Department of Materials Science Department of Materials Chemistry

Single phases of LnAlO 3:Eu 3+ (Ln=Gd,Y) were obtained by the process of evaporation of their nitric acid solution, and then pyrolysis of their nitrate salts. On monitoring by 613 nm emission, broad bands at around 270 and 170 nm were observed in the excitation spectrum of Gd 0.95Eu 0.05AlO 3. These peaks could be assigned to charge transfer (CT) transitions of Eu 3+-O 2- and Gd 3+-O 2- respectively. All the transitions observed in Gd 0.95Eu 0.05AlO 3 are faithfully reproduced in the Y 0.95Eu 0.05AlO 3, but with an exception of the 8S 7/2→ 6I 11/2 transition of Gd 3+. The 153 nm broad band could be the CT transition of Y 3+-O 2-. Accordingly, the efficiency luminescence of (Gd,Y)BO 3:Eu 3+ was explained as a result of CT transitions of Gd 3+-O 2- and Y 3+-O 2- under 147 nm excitation. Under VUV excitation, Gd 0.95Eu 0.05AlO 3 exhibits a bright red luminescence with CIE chromaticity coordinates of (0.623, 0.335) with a PL intensity of 30 of the commercial phosphor (Gd,Y)BO 3:Eu 3+ (KX-504A). The PL spectrum of Y 0.95Eu 0.05AlO 3 is similar to that of Gd 0.95Eu 0.05AlO 3. Calculation of the color coordinates gives x=0.636, y=0.340 with a PL intensity of 50 of the (Gd,Y)BO 3:Eu 3+ (KX-504A) for Y 0.95Eu 0.05AlO 3, and confirms that it has the appearance of pure spectral red, corresponding approximately to 608 nm. It can be concluded that LnAlO 3:Eu 3+ is a promising red VUV phosphor.

A QUANTITATIVE MODEL FOR INTRADAY STOCK PRICE CHANGES BASED ON ORDER FLOWS

引用

Journal of Systems Science & Complexity 2014年第1期27卷 208-224页

This paper proposes a double Markov model of the double continuous auction for describing intra-day price changes. The model splits intra-day price changes as the repetition of one tick price moves and assumes order arrivals are independent Poisson random processes. The dynamic process of price formation is described by a birth-death process of the double M/M/1 server queue corresponding to the best bid/ask. The initial depths of the best bid and ask are defined as different constants depending on the last price change. Thus, the price changes in the model follow a first-order Markov process. As the initial depth of the best bid/ask is originally larger than that of the opposite side when the last price is down/up, the model may explain the negative autocorrelations of the price of the best bid/ask. The estimated parameters are based on the real tick-by-tick data of the Nikkei 225 futures listed in Osaka Stock Exchanges. The authors find the model accurately predicts the returns of Osaka Stock Exchange average.

One Case of Suspected Angiostenosis Revealed by MRA Following Carotid Endarterectomy Due to a Rare Cause

引用

Open Journal of Modern Neurosurgery 2018年第3期8卷 276-281页

作者： Yuji endo naoki Sato Hidekazu Takahashi Mamoru Ota Toshihito Ishikawa Katsuhiro endo Kenichi Ebihara Department of Neurosurgery Masu Memorial Hospital Fukushima Japan Department of Neurosurgery Ageo Central General Hospital Saitama Japan

We herein report on a case in which magnetic resonance angiography (MRA) following carotid endarterectomy revealed the appearance of angiostenosis due to an artifact of metallic powder, which was thought to have come from an old surgical instrument. The patient was a 77-year-old male. Carotid endarterectomy (CEA) was performed for stenosis in the internal carotid artery of his left neck (82%). Upon observing a decline in renal function following CEA surgery, a postoperative cervical MRA revealed the appearance of high-grade stenosis at the common carotid artery on which surgery was performed. No stenosis was revealed upon carotid ultrasonography and angiography. In the original MRA image, an orbicular low intensity area was observed in concordance with the narrow segment. 3D computed tomography (3D-CT) revealed a metallic finding, suggesting it was an artifact caused by metal powder. Close inspection of the metal surgical instruments used during surgery revealed slight damage to a suture snare which had been used for 30 years. Going forward, it is necessary to pay attention to old surgical instruments, introduce a system by which the number of years and the frequency of use of each surgical instrument can be learned, and replace them with new equipment as necessary.

Effect of Water Content on Crystalline Structure of Ionic Liquids Mixture Pretreated Microcrystalline Cellulose (MCC)

引用

Materials Sciences and Applications 2014年第4期5卷 183-192页

作者： Qingyue Wang Qiyu Chen Hiroki Niida naoki Mitsumura Takumi endo Department of Environmental Science and Technology Graduate School of Science and Engineering Saitama University Saitama City Japan

Microcrystalline cellulose (MCC) was pretreated by using ionic liquids (ILs)-water mixtures solvent with solid acid catalysts. Different amount of water was considerate as the main variable. The peak shift of pretreated sample was determined by FT-IR related to the water content. The XRD was applied to characterize the change in MCC crystalline structure. Thermal decomposition technique was applied to investigate the thermal stability of pretreated MCC. The result indicated that three state of samples were occurred in pretreated MCC sample which was related the amount of water in ILs mixture system. XRD result suggested that the raw sample was distorted and transformed into a less ordered intermediate structure and the smaller crystallite size in lump state sample was obtained which could lead to lower thermal stability. This study revealed the physical chemicals properties, characteristic of molecular structures in MCC using ILs-water mixtures.
