| 1 | Neoadjuvant chemotherapy for locally advanced cervical cancer显示文摘Neoadjuvant chemotherapy followed by surgery(NCS) has not been fully evaluated clinically. Currently, the main regimen of neoadjuvant chemotherapy(NAC) used in NCS includes cisplatin. The antitumor effects of NAC reduce lymph node metastasis and the tumor diameter in patients prior to surgery, and this can reduce the number of high risk patients who require postoperative radiation therapy. Many randomized controlled trials(RCTs) have examined the long-term prognosis of NCS compared to primary surgery, but the utility of NCS remains uncertain. The advent of concurrent chemoradiotherapy(CCRT) has markedly improved the outcome of radiotherapy(RT), and CCRT is now used as a standard method in many cases of advanced bulky cervical cancer. NCS gives a better treatment outcome than radiation therapy alone, but it is important to verify that NCS gives a similar or better outcome compared to CCRT. | Takashi Iwata Azumi Miyauchi Yukako Suga Hiroshi Nishio Masaru Nakamura Akiko Ohno Nobumaru Hirao Tohru Morisada Kyoko Tanaka Hiroki Ueyama Hidemichi Watari Daisuke Aoki | 2016 | Chinese Journal of Cancer Research2016，28，2： | 20 |

| 3 | Clinical utility of the platelet-lymphocyte ratio as a predictor of postoperative complications after radical gastrectomy for clinical T2-4 gastric cancer显示文摘AIM To identify simple and sensitive markers for postoperative complications after gastrectomy, the predictive values were compared among candidate preoperative factors. METHODS Three-hundred and twelve patients with previously untreated clinical T2-4 gastric cancer who underwent a D2 standard gastrectomy(distal gastrectomy or total gastrectomy) were included in the analysis.Correlations between 21 parameters that can be determined by preoperative routine blood tests and clinically relevant postoperative complications(grade Ⅱ or higher according to the Clavien-Dindo classification) were evaluated. The optimal cutoff values and clinical significance of the selected markers were further evaluated by subgroup analyses according to age, body mass index, operative procedure and clinical disease stage.RESULTS Sixty-six patients(21.1%) experienced grade Ⅱ or higher postoperative complications. The plateletlymphocyte ratio(PLR, total lymphocyte count/platelet count × 100) exhibited the highest area under the curve value(0.639) for predicting postoperative complications among the 21 parameters, and the optimal cutoff value was determined to be 0.71(sensitivity = 70%, specificity = 56%). In the univariate analysis, the odds ratio of a low PLR for the occurrence of postoperative complications was 2.94(95%CI: 1.66-5.35, P < 0.001), and a multivariate binomial logistic analysis involving other potential risk factors identified a low PLR as an independent risk factor for postoperative complications(OR = 3.32, 95%CI: 1.82-6.25, P < 0.001). In subgroups classified according to age, body mass index, operative procedure and clinical disease stage, the low PLR group exhibited an increased incidence of postoperative complications. CONCLUSION The preoperative PLR is a simple and useful predictor of complications after curative gastrectomy in patients with clinical T2-4 gastric cancer. | Kenichi Inaoka Mitsuro Kanda Hiroaki Uda Yuri Tanaka Chie Tanaka Daisuke Kobayashi Hideki Takami Naoki Iwata Masamichi Hayashi Yukiko Niwa Suguru Yamada Tsutomu Fujii Hiroyuki Sugimoto Kenta Murotani Michitaka Fujiwara Yasuhiro Kodera | 2017 | World Journal of Gastroenterology2017，23，14： | 13 |
| 4 | Elevation of the glycated albumin to glycated hemoglobin ratio during the progression of hepatitis C virus related liver fibrosis显示文摘AIM: To analyze the relationship between the glycated albumin (GA) to glycated hemoglobin (HbA1c) ratio and the histological grading of liver fibrosis.METHODS: The study retrospectively included consecutive hepatitis C virus positive chronic liver disease patients (n = 142) who had undergone percutaneous liver biopsy between January 2008 and March 2010 at our institution. The ratios of GA/HbA1c were calculated in all patients to investigate the relationship with the degree of the liver fibrosis. The values of the aspartate aminotransferase-to-platelet ratio index (APRI), an excellent marker for the evaluation of liver fibrosis, were also calculated. In addition, we combined the ratio of GA/HbA1c and the APRI in order to improve our ability to detect the presence of significant liver fibrosis. RESULTS: Sixty-one (43%) patients had either no fibrosis or minimal fibrosis (METAVIR score: F0-F1), while 25 (17%) had intermediate fibrosis (F2). Fifty-six (39%) patients had severe fibrosis (F3-F4) and 27 of them had cirrhosis (F4). The mean values of the GA/HbA1c increased with the progression of the fibrosis (F0-1: 2.83 ± 0.24, F2: 2.85 ± 0.24, F3: 2.92 ± 0.35, F4: 3.14 ± 0.54). There was a significant dif- ference between the F0-F1 vs F4, F2 vs F4, and F3 vs F4 groups (P < 0.01, P < 0.01, P < 0.01 and P < 0.05, respectively). The GA/HbA1c ratio was significantly higher in the patients with cirrhosis (F4) than in those without cirrhosis (F0-F3) (3.14 ± 0.54 vs 2.85 ± 0.28, P < 0.0001). The GA/HbA1c ratio was also significantly higher in the patients with severe fibrosis (F3-F4) than in those without severe liver fibrosis (F0-F2) (3.03 ± 0.41 vs 2.84 ± 0.24, P < 0.001). Furthermore, the GA/ HbA1c ratio was also significantly higher in the patients with significant fibrosis (F2-F4) than in those without significant liver fibrosis (F0-F1) (2.98 ± 0.41 vs 2.83 ± 0.24, P < 0.001). The diagnostic performance of the increased GA/HbA1c ratio (> 3.0) was as follows: its sensitivity and specificity for the detection of liver cirrhosis (F4) were 59.3% and 70.4%, respectively and its sensitivity and specificity for the detection of severe liver fibrosis (F3-F4) were 50.0% and 74.4%,respectively. With regard to the detection of significant fibrosis (F2-F4), its sensitivity was 44.4% and its specificity was 77.0%. Although even the excellent marker APRI shows low sensitivity (25.9%) for distinguishing patients with or without significant fibrosis, the combination of the APRI and GA/HbA1c ratio increased the sensitivity up to 42.0%, with only a modest decrease in the specificity (from 90.2% to 83.6%). CONCLUSION: The GA/HbA1c ratio increased in line with the histological severity of liver fibrosis, thus suggesting that this ratio is useful as a supportive index of liver fibrosis. | Nobuhiro Aizawa Hirayuki Enomoto Hiroyasu Imanishi Masaki Saito Yoshinori Iwata Hironori Tanaka Naoto Ikeda Yoshiyuki Sakai Tomoyuki Takashima Takashi Iwai Ei-ichiro Moriwaki Soji Shimomura Hiroko Iijima Hideji Nakamura Shuhei Nishiguchi | 2012 | World Journal of Hepatology2012，4，1： | 10 |

| 7 | Body mass index is associated with age-at-onset of HCV-infected hepatocellular carcinoma patients显示文摘AIM: To identify factors associated with the age at onset of hepatitis C virus (HCV)-related hepatocellular carcinoma (HCC). METHODS: Five hundred and fifty-six consecutive patients positive for HCV antibody and treatment-nafive HCC diagnosed between 1995 and 2004 were analyzed. Patients were classified into three groups according to age at HCC onset: < 60 years (n = 79), 60-79 years (n = 439), or ≥ 80 years (n = 38). Differences among groups in terms of sex, body mass index (BMI), lifestyle characteristics, and liver function were assessed. Factors associated with HCC onset in patients < 60 or ≥ 80 years were analyzed by logistic regression analysis. RESULTS: Significant differences emerged for sex, BMI, degree of smoking and alcohol consumption, mean bilirubin, alanine aminotransferase (ALT), and γ-glutamyl transpeptidase (GGT) levels, prothrombin activity, and platelet counts. The mean BMI values of male patients > 60 years old were lower and mean BMI values of female patients < 60 years old were higher than those of the general Japanese population. BMI > 25 kg/m2 [hazard ratio (HR), 1.8, P = 0.045], excessive alcohol consumption (HR, 2.5, P = 0.024), male sex (HR, 3.6, P = 0.002), and GGT levels > 50 IU/L (HR, 2.4, P = 0.014) were independently associated with HCC onset in patients < 60 years. Low ALT level was the only factor associated with HCC onset in patients aged ≥ 80 years. CONCLUSION: Increased BMI is associated with increased risk for early HCC development in HCV-infected patients. Achieving recommended BMI and reducing alcohol intake could help prevent hepatic carcinogenesis. | Takumi Akiyama Toshihiko Mizuta Seiji Kawazoe Yuichiro Eguchi Yasunori Kawaguchi Hirokazu Takahashi Iwata Ozaki Kazuma Fujimoto | 2011 | World Journal of Gastroenterology2011，17，7： | 6 |
| 8 | Human PBMC-transferred murine MHC class I/II-deficient NOG mice enable long-term evaluation of human immune responses显示文摘Immunodeficient mice engrafted with human peripheral blood cells are promising tools for in vivo analysis of human patient individual immune responses.However,when human peripheral blood mononuclear cells(PBMCs)are transferred into NOG(NOD/Shi-scid,IL-2rg null)mice,severe graft versus host disease(GVHD)hinders long term detailed analysis.Administration of human PBMCs into newly developed murine MHC class I-and class II-deficient NOG(NOG-dKO;NOG-Iab,B2m-double-knockout)mice showed sufficient engraftment of human immune cells with little sign of GVHD.Immunization with influenza vaccine resulted in an increase in influenza-specific human IgG Ab,indicating induction of antigen-specific B cells in the NOG-dKO mice.Immunization with human dendritic cells pulsed with HLA-A2 restricted cytomegalovirus peptide induced specific cytotoxic T cells,indicating the induction of antigen-specific T cells in the NOG-dKO mice.Adoptive cell therapies(ACTs)using melanoma antigen recognized by T cells(MART-1)-specific TCR-transduced activated T cells showed strong tumor growth inhibition in NOG-dKO mice without any sign of GVHD accompanied by preferential expansion of the transferred MART-1-specific T cells.ACTs using cultured human melanoma infiltrating T cells also showed anti-tumor effects against autologous melanoma cells in NOG-dKO mice,in which changes in human cancer phenotypes by immune intervention,such as increased CD271 expression,could be evaluated.Therefore,NOG-dKO mice are useful tools for more detailed analysis of both the induction and effector phases of T-cell and B-cell responses for a longer period than regular NOG mice. | Tomonori Yaguchi Asuka Kobayashi Takashi Inozume Kenji Morii Haruna Nagumo Hiroshi Nishio Takashi Iwata Yuyo Ka Ikumi Katano Ryoji Ito Mamoru Ito Yutaka Kawakami | 2018 | Cellular & Molecular Immunology2018，15，11： | 6 |
| 9 | Disruption of Dhcr7 and Insig1/2 in cholesterol metabolism causes defects in bone formation and homeostasis through primary cilium formation显示文摘Human linkage studies suggest that craniofacial deformities result from either genetic mutations related to cholesterol metabolism or high-cholesterol maternal diets. However, little is known about the precise roles of intracellular cholesterol metabolism in the development of craniofacial bones, the majority of which are formed through intramembranous ossification. Here, we show that an altered cholesterol metabolic status results in abnormal osteogenesis through dysregulation of primary cilium formation during bone formation. We found that cholesterol metabolic aberrations, induced through disruption of either Dhcr7(which encodes an enzyme involved in cholesterol synthesis) or Insig1 and Insig2(which provide a negative feedback mechanism for cholesterol biosynthesis), result in osteoblast differentiation abnormalities. Notably, the primary cilia responsible for sensing extracellular cues were altered in number and length through dysregulated ciliary vesicle fusion in Dhcr7 and Insig1/2 mutant osteoblasts. As a consequence, WNT/β-catenin and hedgehog signaling activities were altered through dysregulated primary cilium formation.Strikingly, the normalization of defective cholesterol metabolism by simvastatin, a drug used in the treatment of cholesterol metabolic aberrations, rescued the abnormalities in both ciliogenesis and osteogenesis in vitro and in vivo. Thus, our results indicate that proper intracellular cholesterol status is crucial for primary cilium formation during skull formation and homeostasis. | Akiko Suzuki Kenichi Ogata Hiroki Yoshioka Junbo Shim Christopher AWassif Forbes DPorter Junichi Iwata | 2020 | Bone Research2020，8，1： | 5 |
| 10 | Si nanowire FET and its modeling显示文摘Because of its ability to effectively suppress off-leakage current with its gate-around conffguration, the Si nanowire FET is considered to be the ultimate structure for ultra-small CMOS devices to the extent that the devices would be approaching their downsized limits. Recently, several experimental studies of Si nanowire FETs with on-currents much larger than those of planar MOSFETs have been published. Consequently, Si nanowire FETs are now gaining significant attention as the most promising candidate for mainstream CMOS devices in the 2020s. To enable the introduction of the Si nanowire FETs into integrated circuits, good compact models, which circuit designers can easily handle, are essential. However, it is a very challenging task to establish such a compact model, because the ID - VD characteristics of Si nanowire FETs are affected by the band structure of the nanowire, which is very sensitive to the nanowire diameter, cross-sectional shape, crystal orientation, mechanical stress and interface states. In this paper, the recent status of research on Si nanowire FETs in experimental and theoretical studies is described. | IWAI Hiroshi NATORI Kenji SHIRAISHI Kenji IWATA Jun-ichi OSHIYAMA Atsushi YAMADA Keisaku OHMORI Kenji KAKUSHIMA Kuniyuki AHMET Parhat | 2011 | Science China(Information Sciences)2011，54，5： | 4 |
| 11 | Vitamin K and hepatocellular carcinoma: The basic and clinic显示文摘Vitamin K(VK), which was originally identified as a cofactor involved in the production of functional coagulation factors in the liver, has been shown to be involved in various aspects of physiological and pathological events, including bone metabolism, cardiovascular diseases and tumor biology. The mechanisms and roles of VK are gradually becoming clear. Several novel enzymes involved in the VK cycle were identified and have been shown to be linked to tumorigenesis. The VKs have been shown to suppress liver cancer cell growth through multiple signaling pathways via the transcription factors and protein kinases. A VK2 analog was applied to the chemoprevention of hepatocellular carcinoma(HCC) recurrence after curative therapy and was shown to have beneficial effects, both in the suppression of HCC recurrence and in patient survival. Although a large scale randomized control study failed to demonstrate the suppression of HCC recurrence, a meta-analysis suggested a beneficial effect on the long-term survival of HCC patients. However, the beneficial effects of VK administration alone were not sufficient to prevent or treat HCC in clinical settings. Thus its combination with other anti-cancer reagents and the development of more potent novel VK derivatives are the focus of ongoing research which seeks to achieve satisfactory therapeutic effects against HCC. | Xia Jinghe Toshihiko Mizuta Iwata Ozaki | 2015 | World Journal of Clinical Cases2015，3，9： | 3 |

| 18 | Mechanisms and anatomical risk factors of pneumothorax after Bevacizumab use:A case report显示文摘BACKGROUND Bevacizumab is an antiangiogenic agent,and that synergizes with chemotherapeutic drugs.When used in combination therapies,Bevacizumab is associated with adverse events such as hemorrhage,gastrointestinal perforation,delayed wound healing,and pneumothorax.However,the molecular mechanisms underlying these adverse events are not fully understood.CASE SUMMARY A 45-year-old female with multiple lung metastases that were derived from primary breast cancer,was placed on Bevacizumab+paclitaxel therapy,since this combination has a potent antitumor effect.She reported dyspnea before cycle 3,day 1 and we therefore ran a chest X-ray,which detected a right pneumothorax.The coronal plane computed tomography revealed that one solid mass rapidly necrosed and was replaced by a cavity that passed through the bronchus in the right lower lobe.The cavity eventually ruptured the pleura and made the bronchopleural fistula that led to this pneumothorax.Thoracic cavity drainage using an intercostal catheter was performed.On the 7th day of drainage,the patient was discharged from our hospital on recovery.Recurrence of pneumothorax was not reported,and continuation of chemotherapy was made possible by changing the regimen.CONCLUSION Patients with lung metastases surrounding the bronchi and on the pleura should be monitored for pneumothorax by Bevacizumab-containing chemotherapies. | Yuri Ozaki Akiyo Yoshimura Masataka Sawaki Masaya Hattori Naomi Gondo Haruru Kotani Yayoi Adachi Ayumi Kataoka Kayoko Sugino Nanae Horisawa Yuka Endo Kazuki Nozawa Shoko Sakamoto Hiroji Iwata | 2020 | World Journal of Clinical Oncology2020，11，7： | 2 |
| 19 | Acetylene Vacuum Carburizing显示文摘Almost 30 years has passed since the publication of materials on vacuum carburizing technology, and is attracting a great deal of attention as a technology capable of being used as a substitute for gas carburizing technology. However, the technology was not popular except in specific fields. The main reason for this is due to a variety of harmful influences accompanying the sooting problems caused by CH4 or C3H8. We have succeeded in that the occurrence of sooting was suppressed by utilizing acetylene, at extremely low pressure for carburizing (below 1 kPa). This process is now showing the excellent quality and prospects for this technology in terms of quality, economy and safety. At present almost 70 practical mass production furnaces are used in production lines, in Japan and abroad. At this time, we will report summary of the present acetylene vacuum carburizing process and the actual results obtained by these acetylene vacuum carburizing furnaces for mass production. | Hitoshi Iwata | 2004 | 材料热处理学报2004，25，5： | 2 |
| 20 | First-principles calculation of phase equilibria and phase separation of the Fe-Ni alloy system显示文摘Theoretical investigation of the phase equilibria of the Fe-Ni alloy has been performed by combining the FLAPW total energy calculations and the Cluster Variation Method through the Cluster Expansion Method. The calcula- tions have proved the stabilization of the L12 phase at 1:3 stoichiometry, which is in agreement with the experimental result, and predicted the existence of L10 as a stable phase below 550 K; this L10 phase has been missing in the conventional phase diagram. The calculations are extended to the Fe-rich region that is characterized by a wide range phase separation and has drawn considerable attention because of the intriguing Invar property associated with a Fe concentration of 65%. To reveal the origin of the phase separation, a P-V curve in an entire concentration range is derived by the second derivative of free energy functional of the disordered phase with respect to the volume. The calculation confirmed that the phase separation is caused by the breakdown of the mechanical-stability criterion. The newly calculated phase separation line combined with the L10 and L12 order-disordered phase boundaries provides phase equilibria in the wider concentration range of the system. Furthermore, a coefficient of thermal expansion (CTE) is attempted by incorporating the thermal vibration effect through harmonic approximation of the Debye–Gruneisen model. The Invar behavior has been reproduced, and the origin of this anomalous volume change has been discussed. | Ying Chen Shuichi Iwata Tetsuo Mohri | 2006 | Rare Metals2006，25，5： | 2 |
