| 2 | Differential protein expression in spinal cord tissue of a rabbit model of spinal cordischemia/reperfusion injury显示文摘New Zealand rabbits were randomly divided into an ischemia group(occlusion of the abdominal aorta for 60 minutes),an ischemia-reperfusion group(occlusion of the abdominal aorta for 60 minutes followed by 48 hours of reperfusion) and a sham-surgery group.Two-dimensional gel electrophoresis detected 49 differentially expressed proteins in spinal cord tissue from the ischemia and ischemia/reperfusion groups and 23 of them were identified by mass spectrometry.In the ischemia group,the expression of eight proteins was up regulated,and that of the remaining four proteins was down regulated.In the ischemia/reperfusion group,the expression of four proteins was up regulated,and that of two proteins was down regulated.In the sham-surgery group,only one protein was detected.In the ischemia and ischemia/reperfusion groups,four proteins overlapped between groups with the same differential expression,including three that were up regulated and one down regulated.These proteins were related to energy metabolism,cell defense,inflammatory mechanism and cell signaling. | Qi Gao Yonghui Liang Xiaoyu Yang Guifeng Liu Xiaoxue Li Benqing Zhu Jian Liu Maoguang Yang Weiwei Xia Jian Dong Jianhang Jiao | 2012 | Neural Regeneration Research2012，7，20： | 4 |
| 3 | STABILITY OF DISCRETE-TIME COHEN-GROSSBERG BAM NEURAL NETWORKS WITH DELAYS显示文摘In this paper, we study the existence and stability of an equilibrium of discrete-time Cohen-Grossberg BAM Neural Networks with delays. We obtain several sufficient conditions ensuring the existence and stability of an equilibrium of such systems, using discrete Halanay-type inequality and vector Lyapunov methods. In addition, we show that the proposed sufficient condition is independent of the delay parameter. An example is given to demonstrate the effectiveness of the results obtained. | Zhao Yong (School of Science, Beijing University of Aeronautics and Astronautics, Beijing 100191) Xia Yonghui (College of Math. and Computer Science, Fuzhou University, Fuzhou 350002) | 2008 | Annals of Differential Equations2008，24，4： | 3 |
| 4 | Ginsenoside Rb1 prevents high glucose-induced Schwann cell injury through the mitochondrial apoptosis pathway显示文摘OBJECTIVE: To investigate the effects of ginsenoside Rb1 on high glucose-induced neurotoxicity and the underlying molecular mechanism in primary cultured Schwann cells(SCs).METHODS: Cultured SCs were divided into six groups that received(a) normal glucose,(b) osmotic control,(c) high glucose,(d) high glucose plus 1μM ginsenoside Rb1,(e) high glucose plus 10 μM ginsenoside Rb1, or(f) high glucose plus 100 μM alpha lipoic acid(ALA). Intracellular reactive oxygen species(ROS) generation and mitochondrial transmembrane potential(ΔΨm) were detected by flow cytometric analyses. Apoptosis was confirmed by the annexin V-FITC/propidium iodide(PI) method,and the concentration of 8-hydroxy-2-deoxy guanosine(8-OHd G) was detected by an enzyme-linked immunosorbent assay. Western blotting was performed to analyze the expression levels of important transcription factors such as cytochrome c, bcl-2, bax, activated caspase-3, and activated poly(ADP-ribose) polymerase(PARP).RESULTS: Ginsenoside Rb1 inhibited high glucose-induced oxidative stress by decreasing ROS and 8-OHd G levels as well as mitochondrial depolarization in SCs. 3-(4,5)-dimethylthiahiazo(-z-y1)-3,5-di-phenytetrazoliumromide and annexin V-FITC/PI assays showed that incubating SCs with high glucose decreased cell viability and increased the number of apoptotic cells, whereas treatment with ginsenoside Rb1 protected SCs against high glucose-induced cell damage. Furthermore, ginsenoside Rb1 down-regulated the expression of high glucose-induced bax and cytochrome c release but up-regulated bcl-2 expression. In addition, ginsenoside Rb1 attenuated high glucose-induced activation of caspase-3 and minimized cleavage of PARP in SCs.CONCLUSION: These results suggest that ginsenoside Rb1 antagonizes high glucose-induced oxidative stress and activation of the mitochondrial apoptosis pathway in SCs. | Li Xiaogang Zhang Zhe Wang Rui Xia Xinxin Liu Yonghui Sun Lianqing | 2017 | Journal of Traditional Chinese Medicine2017，37，6： | 3 |
| 5 | In Vivo Study on Degradation Behavior and Histologic Response of Pure Magnesium in Muscles显示文摘When an orthopedics device is implanted into bone injury site, it will contact the soft tissue(skeletal muscle, fascia, ligament etc.) except for bone. Magnesium based biodegradable metals are becoming an important research object in orthopedics due to their bioactivity to promote bone healing. In this study,pure Mg rods with and without chemical conversion coating were implanted into the muscle tissue of rabbits. Implants and their surrounding tissues were taken out for weight loss measurement, crosssectional scanning electron microscopy observation, elemental distribution analysis and histological examination. The results showed that the chemical conversion coating would increase the in vivo corrosion resistance of pure Mg and decrease the accumulation of calcium(Ca) and phosphorus(P) elements around the implants. For the bare magnesium implant, both Ca and P contents in the surrounding tissues increased at the initial stage of implantation and then decreased at 12 weeks implantation, while for the magnesium with chemical conversion coating, Ca and P contents in the surrounding tissues decreased with the implantation time, but were not significant. The histological results demonstrated that there was no calcification in the muscle tissue with implantation of magnesium for up to 12 weeks. The chemical conversion coating not only increased the in vivo corrosion resistance of pure Mg, but also avoided the depositions of Ca and P in the surrounding tissues, meaning that pure magnesium should be biosafe when contacting with muscle tissues. | Shanshan Chen Lili Tan Bingchun Zhang Yonghui Xia Ke Xu Ke Yang | 2017 | Journal of Materials Science & Technology2017，33，5： | 2 |

| 7 | Chiral phase diagram of strongly interacting matter at finite volume显示文摘At extremely high temperature T~200 Me V and low chemical potentialμ,the quarks and gluons get released from the nucleon and form the quark-gluon plasma(QGP)state,which is accessible in the heavy ion collisions(HIC)globally[1,2].Theoretically,ab initio lattice QCD simulation found the transition from hadrons to QGP at lowμis continuous crossover instead of phase transition.In this connection,RHIC is running the beam energy scan program to look into the territory with higherμ[3].One important goal is to determine if there is the first order phase transition as expected by many model studies and locate the critical end point(CEP)if it exists. | Chao Shi YongHui Xia WenBao Jia HongShi Zong | 2018 | Science China(Physics,Mechanics & Astronomy)2018，61，8： | 1 |
