| 3 | 高强度聚焦超声治疗不能手术胰腺癌的1年生存分析:中国和保加利亚的多中心临床研究显示文摘目的:通过多中心临床研究分析高强度聚焦超声治疗不能手术胰腺癌的1年生存情况。方法:2013年1月到2014年1月,中国和保加利亚的不能手术的胰腺癌患者32例,男/女=20/12,年龄41~81(59.8±9.1)岁。胰腺癌病灶最大径20~60(39.3±9.6)mm,远处转移/无转移的患者18/14例。接受HIFU和/或化疗。记录术后并发症,疼痛变化和生存情况。使用Kaplan-Meier法计算总生存率和中位生存时间,比较化疗与否、是否发生远处转移的患者生存率有无差异(Log-Rank检验)。结果:术后1月,皮肤浅Ⅱ°烧伤者2例,经保守处理后1~2周愈合。伴有胰腺癌相关性疼痛症状的患者30例与术前比较,减轻的24例(80.0%),不变的5例(16.7%),加重的1例(3.3%)。所有患者的1年生存率为38.4%,中位生存时间为12个月。接受辅助化疗的患者1年生存率为57.4%,中位生存时间12月;未接受辅助化疗的患者1年生存率为20.8%,中位生存时间为6月;二者间比较有显著性差异。伴有远处转移的患者1年生存率为0%,中位生存时间为7月;无远处转移的患者1年生存率为49.2%,中位生存时间为12月;二者间比较无统计学差异。结论:中国和保加利亚的不能手术胰腺癌患者均能安全完成HIFU治疗,1年生存率和中位生存时间优于其它非手术治疗手段。辅助化疗能增加生存受益,远处转移是预后不良因素。 | 周崑 Dobromir Dimitrov Dimitrov Tihomir Vencislavov Andreev 汪亮 Hyuliya Erdzhanova Feradova Grigor Angelov Gorchev 朱辉 王智彪 | 2015 | 重庆医科大学学报2015,40,3: | 11 |
| 4 | 掺硫硒化镓晶体在太赫兹波段的光学特性显示文摘利用太赫兹时域光谱技术测量了掺硫硒化镓(GaSe1-xSx)晶体在太赫兹波段的光学参数,包括折射系数、吸收系数等。使用自由空间电光取样法获得了太赫兹电磁波的脉冲波形,对不同硫掺杂量的硒化镓晶体进行了研究,在硫的掺杂量为0,0.01,0.14,0.26,0.37时,在0.22.0 THz测得了GaSe1-xSx的折射系数、吸收系数等光学参数。此外还在吸收光谱上观察到E′^(2)和E″^(2)两个声子振动模态,其强度与频率会随着硫的掺杂量而改变,且即使是微量的硫掺杂也会影响吸收光谱上的声子振动模态。最后,在相位匹配ee-e的条件下,模拟了利用锁模钛蓝宝石激光使此类晶体产生太赫兹辐射的可能性。 | 罗志伟 古新安 朱韦臻 唐维聪 ANDREEV YURY LANSKII Grigory MOROZOV Alexander ZUEV Vladimir | 2011 | 光学精密工程2011,19,2: | 10 |
| 5 | Estrogen-mediated downregulation of HIF-1αsignaling in B lymphocytes influences postmenopausal bone loss显示文摘In the bone marrow, B cells and bone-resorbing osteoclasts colocalize and form a specific microenvironment. How B cells functionally influence osteoclasts and bone architecture is poorly understood. Using genetically modified mice and highthroughput analyses, we demonstrate that prolonged HIF-1α signaling in B cells leads to enhanced RANKL production and osteoclast formation. In addition, deletion of HIF-1α in B cells prevents estrogen deficiency-induced bone loss in mice.Mechanistically, estrogen controls HIF-1α protein stabilization through HSP70-mediated degradation in bone marrow B cells.The stabilization of HIF-1α protein in HSP70-deficient bone marrow B cells promotes RANKL production and osteoclastogenesis.Induction of HSP70 expression by geranylgeranylacetone(GGA) administration alleviates ovariectomy-induced osteoporosis.Moreover, RANKL gene expression has a positive correlation with HIF1 A expression in human B cells. In conclusion, HIF-1αsignaling in B cells is crucial for the control of osteoclastogenesis, and the HSP70/HIF-1α axis may serve as a new therapeutic target for osteoporosis. | Xianyi Meng Zhen Lin Shan Cao Iga Janowska Koshiro Sonomoto Darja Andreev Knab Katharina Jinming Wen Karl Xaver Knaup Michael Sean Wiesener Gerhard Krönke Marta Rizzi Georg Schett Aline Bozec | 2022 | Bone Research2022,10,2: | 6 |
| 6 | GaSe:AgGaSe_2晶体的光学性能及应用(英文)显示文摘从GaSe:AgGaSe2熔体(质量掺杂浓度为10%)中生长的非线性光学晶体ε-GaSe:Ag晶体(质量掺杂浓度≤0.04%)是一种非中心对称晶体,可用于相位匹配频率转换。Ag的掺入使GaSe晶体的显微硬度提高了30%,从而使其可以在任意方向上进行切割和抛光。本文研究了GaSe:AgGaSe2晶体在可见、中红外及太赫兹波段的光学性能。实验证明:GaSe:AgGaSe2晶体的吸收系数是纯GaSe晶体的2倍,其CO2激光倍频效率是ZnGeP2晶体的1.7倍。 | 古新安 朱韦臻 罗志伟 ANGELUTS A A EVDOKIMOV M G NAZAROV M M SHKURINOV A P ANDREEV Y M LANSKII G V SHAIDUKO A V KOKH K A SVETLICHNYI V A | 2012 | 中国光学2012,5,1: | 5 |
| 7 | Major Trends in Population Growth Around the World显示文摘Summary The world’s population continues to grow,albeit at a slower pace.The decelerating growth is mainly attributable to fertility declines in a growing number of countries.However,there are substantial variations in the future trends of populations across regions and countries,with sub-Saharan African countries being projected to have most of the increase. | Danan Gu Kirill Andreev Matthew E.Dupre | 2021 | China CDC weekly2021,3,28: | 3 |
| 8 | 掺碲硒化镓晶体的光学性能(英文)显示文摘采用水平区熔法生长了碲(Te)掺杂浓度(质量百分比)分别为0.05%,0.1%,0.5%,1%,2%的硒化镓(GaSe)晶体,并分别对掺杂浓度为0.01%,0.07%,0.38%,0.67%,2.07%的GaSe∶Te晶体的光学性能进行了表征。首次研究了GaSe∶Te晶体中刚性层声子模式的转换。吸收光谱测试结果表明:当Te掺杂浓度小于0.38%时,振动中心位于0.59 THz附近的E'(2)刚性模式吸收峰强度可达最大值,这一过程与GaSe∶Te晶体光学性能的提高密切相关。但Te掺杂浓度的进一步提高会导致E'(2)刚性模式吸收峰强度逐渐减弱,当Te掺杂浓度为1%时,E'(2)刚性模式吸收峰基本消失。这两个过程与GaSe∶Te晶体光学质量的下降密切相关。因此,E'(2)刚性模式吸收强度达到最高时对应的掺杂浓度即是GaSe∶Te晶体中Te的最佳掺杂浓度,光整流产生太赫兹过程证实了此结论的正确性。 | 古新安 朱韦臻 罗志伟 ANDREEV Y M LANSKII G V SHAIDUKO A V IZAAK T I SVETLICHNYI V A VAYTULEVICH E A ZUEV V V | 2011 | 中国光学2011,4,6: | 3 |

| 11 | Assessments of mortality at oldest-old ages by province in China's 2000 and 2010 censuses显示文摘This study examined the possible underestimation and age-trajectories of mortality at oldest-old ages in China’s 2000 and 2010 censuses.By linking logit-transformed conditional probabilities of dying from 13 countries with the highest data quality in the world,this study found that many Chinese provinces had underestimations of mortality at oldest-old ages when a relatively lenient criterion was applied.When a relatively strict criterion was applied,most provinces had a 30%or more underestimation in the probability of dying.We also investigated age trajectories of death rates after age 80 in these two censuses by applying the Kannisto model.Results showed that the age trajectories were distorted in most provinces after age 95.Overall,eastern-coastal provinces had higher data quality—in terms of low underestimation rates and less distorted age trajectories—whereas western China had provinces with problematic data.Females had greater rates of underestimation yet less distorted age-trajectories than males;and the 2010 census had greater rates of underestimation yet less distorted age-trajectories than the 2000 census.We conclude that appropriate adjustments with simultaneous applications of the Kannisto model are needed for direct estimates of mortality at oldest-old ages in the 2000 and 2010 censuses for China and for its provinces. | Danan Gu Runlong Huang Kirill Andreev Matthew E.Dupre Yaer Zhuang Hongyan Liu | 2016 | International Journal of Population Studies2016,2,2: | 2 |
| 12 | GaSe晶体的CO_2激光倍频及其色散特性研究显示文摘为了研究GaSe晶体的倍频(SHG)及色散性质,采用声光调Q可调谐线偏振CO2脉冲激光器,在250 Hz重频脉冲下以共线oo-e相位匹配方式作用于GaSe晶体,得到CO2激光的可调谐SHG输出。测量了基频波长为9.3、9.6、10.3和10.6μm时的相位匹配角,并通过对比现有文献中色散方程的相位匹配角计算结果和测量结果,确定出最适用于GaSe晶体的色散方程。实验对SHG信号与晶体中光束方位角φ的关系进行测量。本文实验可以作为间接测量晶体色散关系的方法,为GaSe晶体的进一步研究打下基础;同时也可为其它非线性晶体的研究提供参考。 | 姜可 谢冀江 张来明 李殿军 谢京江 Yury Andreev | 2013 | 光电子.激光2013,24,5: | 2 |
