Effect of Hyperbaric Oxygen on the Growth of Intracranial Glioma in Rats

Chinese Medical Journal 2015年第23期128卷 3197-3203页

Background： Numerous studies have confirmed that hyperbaric oxygen （Hbo） in combination with radiotherapy or chemotherapy may increase the efficacy of radiotherapy or chemotherapy in patients with glioma. However, whether Hbo therapy alone may inhibit or promote the growth of malignant tumors remains controversial. This study aimed to investigate the effect of Hbo on the growth of glioma in rats, and the impact of Hbo on the expression of vascular endothelial growth factor （VEGF） and hypoxia-inducible factor 1-alpha （HIF-1α）, angiogenesis, and apoptosis of glioma cells. Methods： Male Sprague-Dawley rats were treated with or without Hbo after glioma cell inoculation and followed for up to 16 days postinoculation. Rats were randomized to receive bilateral forelimb function tests （n = 20 per group） and head magnetic resonance imaging （n = 5 per group）. Differences between Hbo and control groups were tested using 2-sample independent t-tests and changes over time within treatment groups were analyzed using a repeated measurement analysis of variance with bonferroni correction. The effect of H bo on the expression of VEGF, HIF-1α, yon Willebrand factor, angiogenesis, and tumor cell apoptosis were also examined （n = 5 per group）. Results： Forelimb function scores were reduced in both Hbo-treated and control groups. Hbo-treated rats had significantly larger tumor volume and more water in the cerebellum compared with control rats. The intratumoral expression of VEGF was significantly higher in Hbo-treated rats compared with control rats （23.2% vs. 13.3%, P = 0.002）. HIF-1α was significantly increased in Hbo-treated rats compared with controls in the expression of both intratumoral （72.7% vs. 54.9%, P= 0.001） and peritumoral （2.6% vs. 1.9%, P = 0.003） cells. The intratumoral microvessel density （MVD） was significantly higher in the Hbo group （15.6 vessels/field vs. 4.4 vessels/field. P 〈 0.001 ）, and the peritumoral MVD was not significantly different between the two groups

The Large sky Area Multi-Object Fiber Spectroscopic Telescope（LAMOST） general survey is a spectroscopic survey that will eventually cover approximately half of the celestial sphere and collect 10 million spectra of stars, galaxies and QSOs. Objects in both the pilot survey and the first year regular survey are included in the LAMOST DR1. The pilot survey started in October 2011 and ended in june 2012, and the data have been released to the public as the LAMOST Pilot Data Release in August 2012. The regular survey started in September 2012, and completed its first year of operation in june 2013. The LAMOST DR1 includes a total of 1202 plates containing 2 955 336 spectra, of which 1 790 879 spectra have observed signalto-noise ratio（SNR） ≥ 10. All data with SNR ≥ 2 are formally released as LAMOST DR1 under the LAMOST data policy. This data release contains a total of 2 204 696 spectra, of which 1 944 329 are stellar spectra, 12 082 are galaxy spectra and 5017 are quasars. The DR1 not only includes spectra, but also three stellar catalogs with measured parameters： late A,FGK-type stars with high quality spectra（1 061 918 entries）, A-type stars（100 073 entries）, and M-type stars（121 522 entries）. This paper introduces the survey design, the observational and instrumental limitations, data reduction and analysis, and some caveats. A description of the FITS structure of spectral files and parameter catalogs is also provided.

Disappearance of Superconductivity and a Concomitant Lifshitz Transition in Heavily Overdoped Bi_2Sr_2CuO_6 Superconductor Revealed by Angle-Resolved Photoemission Spectroscopy

引用

Chinese Physics Letters 2019年第1期36卷 60-64页

作者： Ying ding Lin Zhao hong-Tao Yan Qiang Gao Jing Liu cheng Hu jian-Wei Huang Cong Li Yu xu yong-qing Cai hong-Wao Rong ding-Song Wu Chun-Yao Song Hua-xue Zhou Xiao-Li Dong Guo-Dong Liu qing-Yan Wang Shen-Jin Zhang zhi-Min Wang Feng-Feng Zhang Feng Yang qin-junPeng Zu-Yan xu Chuang-Tian chen X.J.Zhou Beijing National Laboratory for Condensed Matter Physics Institute of Physics Chinese Academy of Sciences Technical Institute of Physics and Chemistry Chinese Academy of Sciences Collaborative Innovation Center of Quantum Matter

By partially doping Pb to effectively suppress the superstructure in single-layered cuprate Bi_2Sr_2CuO_(6+δ)(Pb-Bi2201) and annealing them in vacuum or in high pressure oxygen atmosphere, a series of high quality Pb-Bi2201 single crystals are obtained with T_c covering from 17 K to non-superconducting in the overdoped region. High resolution angle resolved photoemission spectroscopy measurements are carried out on these samples to investigate the evolution of the Fermi surface topology with doping in the normal state. Clear and complete Fermi surfaces are observed and quantitatively analyzed in all of these overdoped Pb-Bi2201 samples. A Lifshitz transition from holelike Fermi surface to electron-like Fermi surface with increasing doping is observed at a doping level of ~0.35. This transition coincides with the change that the sample undergoes superconducting-to-non-superconducting *** results reveal the emergence of an electron-like Fermi surface and the existence of a Lifshitz transition in heavily overdoped Bi2201 samples. This provides important information in understanding the connection between the disappearance of superconductivity and the Lifshitz transition in the overdoped region.

目的观察高压氧预处理（Hyperbaric oxygen preconditioning,HboP）对大鼠脑出血后脑水肿和血肿周围炎症反应及神经细胞凋亡的影响.方法选用36只雄性Sprague-Dawley大鼠（体质量300～350 g）,其中18只大鼠接受连续5次HboP（HboP组：3个绝对大气压,100%O2,每次1 h,1次/d,连续5 d）,另18只大鼠接受连续五次假预处理（对照组：1个绝对大气压,空气,每次1 h,1次/d,连续5d）.预处理结束24 h后,立体定向基底节内注射自体股动脉血100μL建立基底节脑出血模型,72 h后处死,采用干湿重法测定脑组织水含量（24只大鼠,HboP组及对照组各12只）;采用HE染色镜下观察血肿周围炎症细胞浸润,采用缺口末端标记法（TUNEL）检测神经细胞凋亡（12只大鼠,HboP组及对照组各6只）;统计学分析采用stata 7.0统计软件对脑组织水含量值进行成组设计资料的t检验.结果 HboP组脑出血72 h后血肿周围基底节脑组织水含量显著低于对照组[（81.6±0.7）%vs.（82.8±0.9）%,（P〈0.01）];血肿周围炎症细胞浸润程度显著轻于对照组,血肿周围凋亡细胞显著少于对照组.结论 HboP显著减轻脑出血后脑水肿,显著抑制脑出血后炎症反应以及减少神经细胞凋亡.
