| 2 | SDF-1/CXCR4 axis modulates bone marrow mesenchymal stem cell apoptosis, migration and cytokine secretion显示文摘Bone marrow mesenchymal stem cells(MSCs)are considered as a promising cell source to treat the acute myocardial infarction.However,over 90%of the stem cells usually die in the first three days of transplantation.Survival potential,migration ability and paracrine capacity have been considered as the most important three factors for cell transplantation in the ischemic cardiac treatment.We hypothesized that stromal-derived factor-1(SDF-1)/CXCR4 axis plays a critical role in the regulation of these processes.In this study,apoptosis was induced by exposure of MSCs to H2O2 for 2 h.After re-oxygenation,the SDF-1 pretreated MSCs demonstrated a significant increase in survival and proliferation.SDF-1 pretreatment also enhanced the migration and increased the secretion of pro-survival and angiogenic cytokines including basic fibroblast growth factor and vascular endothelial growth factor.Western blot and RT-PCR demonstrated that SDF-1 pretreatment significantly activated the pro-survival Akt and Erk signaling pathways and up-regulated Bcl-2/Bax ratio.These protective effects were partially inhibited by AMD3100,an antagonist of CXCR4.We conclude that the SDF-1/CXCR4 axis is critical for MSC survival,migration and cytokine secretion. | Xiaolei Liu Biyan Duan Zhaokang Cheng Xiaohua Jia Lina Mao Hao Fu Yongzhe Che Lailiang Ou Lin Liu Deling Kong | 2011 | Protein & Cell2011，2，10： | 53 |

| 4 | The expression of estrogen receptors in thyroid cancer and its significance显示文摘Objective The study aimed to detect the expression of estrogen receptors(ERs) in thyroid cancer and investigate the correlation between their expression and clinical features and different pathological types.Methods The expression of ERs in 56 samples of thyroid cancer tissues was detected by an immunochemical approach. The expression of ERs in thyroid cancer tissues and different pathological types were analyzed using the χ~2 test. Results The number of cases with positive expression of ER in thyroid cancer tissues was 36. The number of papillary thyroid cancers(PTCs) was 48, with positive expression of ERs in 32 cases. The number of follicular thyroid cancers was 4, with positive expression of ERs in 2 cases. The number of medullary thyroid cancers was 4, with negative expression of ERs in all cases. The difference between the expression and different pathological types showed statistical significance. The expression of ERs showed no correlation with sex, age, or TNM stage, with no statistical significance. However, the expression of ERs was correlated with metastasis of lymph nodes, which had statistical significance. The expression of ERs was negatively correlated with pathological types and metastasis of lymph nodes. The correlated coefficient index was –0.313 and –0.334, respectively. Conclusion The expression of ERs showed no correlation with sex, age, or TNM stage, but was negatively correlated with pathological types and metastasis of lymph nodes. | Yuxuan Che Huamin Qin Xiaolei Ding Xiuhua Sun Lifen Wang | 2017 | Oncology and Translational Medicine2017，3，3： | 1 |
| 5 | A joint call for actions to advance taxonomy in China显示文摘Taxonomy plays an important role in understanding the origin, evolution, and ecological functionality of biodiversity. There are large number of unknown species yet to be described by taxonomists, which together with their ecosystem services cannot be effectively protected prior to description. Despite this, taxonomy has been increasingly underrated insufficient funds and permanent positions to retain young talents. Further, the impact factordriven evaluation systems in China exacerbate this downward trend, so alternative evaluation metrics are urgently necessary. When the current generation of outstanding taxonomists retires,there will be too few remaining taxonomists left to train the next generation. In light of these challenges, all co-authors worked together on this paper to analyze the current situation of taxonomy and put out a joint call for immediate actions to advance taxonomy in China. | Chaodong Zhu Arong Luo Ming Bai Michael COrr Zhonge Hou Siqin Ge Jun Chen Yibo Hu Xuming Zhou Gexia Qiao Hongzhi Kong Limin Lu Xiaohua Jin Lei Cai Xinli Wei Ruilin Zhao Wei Miao Qingfeng Wang Zhongli Sha Qiang Lin Meng Qu Jianping Jiang Jiatang Li Jing Che Xuelong Jiang Xiaoyong Chen Lianming Gao Zongxin Ren Chunlei Xiang Shixiao Luo Donghui Wu Dong Liu Yanqiong Peng Tao Su Chenyang Cai Tianqi Zhu Wanzhi Cai Xingyue Liu Hu Li Huaijun Xue Zhen Ye Xuexin Chen Pu Tang Shujun Wei Hong Pang Qiang Xie Feng Zhang Feng Zhang Xianjin Peng Aibing Zhang Taiping Gao Changfa Zhou Chen Shao Libin Ma Zhaoming Wei Yunxia Luan Ziwei Yin Wu Dai Cong Wei Xiaolei Huang Jingxian Liu Xiangsheng Chen Tianci Yi Zhisheng Zhang Zhulidezi Aishan Qin Li Hongying Hu | 2022 | Zoological Systematics2022，47，3： | 1 |
| 6 | Investigation of Voids in Polyacrylonitrile Fibers by USAXS and SAXS显示文摘The void structure of polyacrylonitrile(PAN)fibers was investigated using ultra-small angle X-ray scat-tering(USAXS)and small angle X-ray scattering(SAXS).A quantitative method was developed to analyze connected USAXS/SAXS data and thus determine the void parameters of PAN fibers.The results showed that voids affected the mechanical performance of PAN fibers and were present throughout the entire wet-spinning process.When the abso-lute quantity and size of voids decreased,the tensile strength and modulus of PAN fibers increased.The void para-meters were optimized by controlling the production process,and thus the tensile strength and modulus of PAN fibers were increased.The method for analyzing the void structure developed in this study is useful for analyzing voids over with larger size range,as well as the effect of the void structure on the mechanical performance of fibers. | TANG Haitong MENG Fanling LIU Yan JIN Shi WANG Xiaodong GAO Zhongmin CHE Xiaolei | 2019 | Chemical Research in Chinese Universities2019，35，6： | 1 |

| 8 | Multi-mode Multi-frequency GNSS-IR Combination System for Sea Level Retrieval显示文摘With the development of Global Navigation Satellite Systems(GNSS),geodetic GNSS receivers have been utilized to monitor sea levels using GNSS-Interferometry Reflectometry(GNSS-IR)technology.The multi-mode,multi-frequency signals of GPS,GLONASS,Galileo,and Beidou can be used for GNSS-IR sea level retrieval,but combining these retrievals remains problematic.To address this issue,a GNSS-IR sea level retrieval combination system has been developed,which begins by analyzing error sources in GNSS-IR sea level retrieval and establishing and solving the GNSS-IR retrieval equation.This paper focuses on two key points:time window selection and equation stability.The stability of the retrieval combination equations is determined by the condition number of the coefficient matrix within the time window.The impact of ill-conditioned coefficient matrices on the retrieval results is demonstrated using an extreme case of SNR data with only ascending or descending trajectories.After determining the time window and removing ill-conditioned equations,the multi-mode,multi-frequency GNSS-IR retrieval is performed.Results from three International GNSS Service(IGS)stations show that the combination method produces high-precision,high-resolution,and high-reliability sea level retrieval combination sequences. | Wenyue CHE Xiaolei WANG Xiufeng HE Jin LIU | 2023 | Journal of Geodesy and Geoinformation Science2023，6，2： | 0 |
| 9 | Formation and growth of precipitates in a Mg-7Gd-5Y-1Nd-2Zn-0.5Zr alloy aged at 200℃显示文摘Crystal structures,growth characteristics,and transformation of the precipitates in a Mg-7Gd-5Y-1Nd-2Zn-0.5Zr(wt.%)alloy aged at 200℃for various durations were investigated using transmission electron microscopy(TEM)and high-angle annular dark-field scanning transmission electron microscopy(HAADF-STEM).A detailed Mg-Gd type precipitation sequence for Mg-Gd-Y-Nd-Zn alloys was proposed as follows:supersaturated solid solution→solute clusters→zigzag GP zones+β''(I)→β'→β'+protrusions/joints→pre-β_(1)→β_(1)→β.Solute clusters formed in the early stage of aging consisted of one or more rare-earth(RE)/Zn-rich atomic columns with different configura-tions.RE/Zn-rich solute clusters grew into zigzag GP zones andβ''(I)as aging time extending.The paired-zigzag GP zones might grow up to beβ'precipitates directly.In the peak-and plat-aging stages,the number of solute clusters in the matrix decreased until they disappeared,and most existed as zigzag arrays and super hexagons.Protrusions formed at the end ofβ'at an angle of 120°,then grew into joints when two differentβ'variants encountered together.Protrusions/joints comprise zigzag arrays,super-hexagons,β'F,β''(II),β_(T),and hybrid structures rich in solute atoms,and act as catalysts for the growth of theβ'variants.Largerβ'grow by joints consumption while smallerβ'precipitates dissolve to form joints.β_(1)precipitates essentially evolve from pre-β_(1)precipitates,with four-point diamond structures formed by RE/Zn atomic substitution and atomic migration based on the originalα-Mg structure. | Zhiwei Du Yonggang Peng Hang Teng Zhong Cao Kui Zhang Minglong Ma Xiaolei Han Ting Li Cong Che Yongjun Li | 2023 | Journal of Magnesium and Alloys2023，11，7： | 0 |
