| 1 | Effect of electroacpuncture of Neiguan(PC 6)and Tianquan(PC 2)on skin temperature,blood perfusion,and adrenoceptor response in rats with acute myocardial ischemia显示文摘OBJECTIVE: To investigate the effect of electroacupuncture(EA) of acupoints Neiguan(PC 6) and Tianquan(PC 2) on the skin temperature, blood perfusion, and alpha1-and beta2-adrenoreceptor(α1-AR and β2-AR) protein and m RNA level in rats with acute myocardial ischemia.METHODS: Thirty male adult Wistar rats [(230 ±20) g] were randomly assigned into five groups(n = 6 each): a control group, sham operation group, model group, model group treated with EA at low frequency(L-EA, 2 Hz, 1 m A) and model group treated with EA at high frequency(H-EA, 100 Hz, 1 m A). The rat model was prepared by ligating the left anterior descending coronary artery. Electroacupuncture was performed at the left Neiguan(PC 6) for 20 min daily for 3 d. After the 3 rd time of the treatment, measurements of skin blood perfusion and temperature in Neiguan(PC 6) and Tianquan(PC 2) in all groups were made by laser speckle contrast imaging and infrared thermal image instrument. Real-time PCR and ELISA were used to measure m RNA level and protein level of α1-AR andβ2-AR in the skin tissues of Neiguan(PC 6) and Tianquan(PC 2), respectively. Serum levels of c Tn T and electrocardiogram were used to identify the state of myocardium.RESULTS: In the group receiving electroacupunture at Neiguan(PC 6), compared with control group,the skin temperature, blood perfusion, and β2-AR m RNA and protein level of model group significantly decreased(P < 0.05), α1-AR m RNA and protein level of model group significantly increased(P < 0.05);compared with model group, the skin temperature,blood perfusion, and β2-AR m RNA and protein level of L-EA significantly increased(P < 0.05), α1-AR m RNA and protein level of L-EA and H-EA significantly decreased(P < 0.05). The same trend has taken place in the former four groups of the Tianquan(PC 2).CONCLUSION: Low-or high-frequency electroacupuncture can improve the skin temperature and blood perfusion which may be induced by decreasingthelevelofα1-ARandincreasingthelevelofβ2-AR of the Neiguan(PC 6) and Tianquan(PC 2) in the rat with acute myocaidial ischemia. | Wang Dan Ji Bo Zhao Guozhen Yan Mingna Bai Hongxin Sun Xiaomin Dai Jian Lu Yawen Liu Yitian You Min Wu Jiaojuan Ge Yunpeng Su Hang Cheng Kai | 2017 | Journal of Traditional Chinese Medicine2017，37，6： | 3 |

| 6 | Effects of Nickel on the Microstructure,Mechanical properties and Corrosion Resistance of CoCrFeNi_(x)Al_(0.15)Ti_(0.1)High Entropy Alloy显示文摘The present work investigates the effect of Ni on the microstructure,mechanical properties,and corrosion resistance of CoCrFeNi_(x)Al_(0.15)Ti_(0.1)high-entropy alloys.It was found that the appropriate addition of Ni element in the alloy is beneficial to reduce the average grain size of the alloy.The yield strength and tensile strength of the alloy underfine-grain strengthening have also been increased,whilethe ductility of the system in this study has not been significantly affected.In terms of corrosion resistance,CoCrFeNi_(x)Al_(0.15)Ti_(0.1)high-entropy alloys form a dense passive film at open circuit potential,possessing good corrosion resistance.However,with the excessive addition of Ni content in the alloy,the pitting corrosion resistance of the alloy in the environment of chloride ions will decrease due to the relative decrease of the relative content of Cr element.This work also canprovide guidancesfor the design and development of new precipitation-strengthened CoCrFeNi-based high-entropy alloys with excellent comprehensive properties. | Wu QI Yitian SU Xiao YANG Guannan ZHANG Yi ZHAO Ya ZHANG Wenrui WANG | 2022 | Research and Application of Materials Science2022，4，2： | 0 |
