| 1 | Preface to the Special Issue on Advanced Analog and Mixed- Mode Integrated Circuits显示文摘High performance analog and mixed signal circuits are strongly demanded in todays’system on chip systems.They found pervasive applications in A/D or D/A conversion,power management,radio frequency(RF)signal sensing and processing,clock generation,etc.In this special issue,we collected 7 comprehensive reviews and 2 research articles from leading research groups,which presented state-of-art design techniques and insight forecast of development trend in this hot area. | Baoyong Chi Nan Sun Liyuan Liu Yan Lu | 2020 | Journal of Semiconductors2020，41，11： | 0 |
| 2 | Expression of CXCL12-CXCR4 in osteosarcoma and its correlation with angiogenesis显示文摘Objective The expression of CXCL12(stromal cell-derived factor-1)-CXCR4(chemokine receptors-4) in osteosarcoma and its role in angiogenesis were examined.Methods The expression of CXCR4 and CXCL12 in 40 cases of osteosarcoma was detected by immunohistochemistry and real-time fluorescence quantitative PCR.The expression of CD34 in osteosarcoma was detected by immunohistochemistry.Morphometric image analysis was performed to measure microvessel density(MVD).Additionally,the relationship between CXCL12 and CXCR4 expression and MVD of osteosarcoma and pulmonary metastasis were analyzed.Results The positive rates of CXCL12 and CXCR4 protein expression in osteosarcoma were 40.0%(16/40) and 60.0%(24/40),respectively.Fluorescence quantitative real-time PCR indicated that the expression level of CXCR4 m RNA in pulmonary metastatic osteosarcoma was higher than that in nonpulmonary metastatic osteosarcoma(P < 0.01).The level of MVD in pulmonary metastatic osteosarcoma was higher than that in non-pulmonary metastatic osteosarcoma(P < 0.01).Conclusion The expression level of CXCR4 was significantly associated with pulmonary metastasis and angiogenesis of osteosarcoma. | Lu Han Yangyang Shen Wenhua Zhao Baoyong Sun Xin Zhang Kai Cui Lei Zhou Sheng Li | 2017 | Oncology and Translational Medicine2017，3，6： | 0 |
| 3 | A Ka-band calibratable phased-array front-end chip with high element-consistency显示文摘Dear editor,Active phased arrays are widely used in radar and communication systems due to their characteristics such as rapid wave beam steering, agile beamforming, and spatial power synthesis. The phased-array system contains a large number of elements. Three critical components in each element are precise amplitude control, precise phase control, and signal amplification. | Shiyan SUN An'an LI Yingtao DING Zipeng CHEN Wei WANG Sijia JIANG Zhiming CHEN Baoyong CHI | 2022 | Science China(Information Sciences)2022，65，12： | 0 |
