| 2 | Efficacy on rabbits with arrhythmia: needling acupoint of Neiguan(PC6) at shallow or deep depth, and retaining needles for 10, 20, or 30 min显示文摘OBJECTIVE:To compare the effects of Neiguan(PC6)acupuncture at different depths and retention time on arrhythmia duration,myocardial tissue morphology,mRNA expression level of L-type calcium channelα1C subunit and Ca^(2+)-Mg^(2+)-At Pase activity in tachirrhythmia model of rabbits.METHODS:The tachyarrhythmia model was made by intravenous injection of barium chloride into the ears of rabbits.A total of 56 healthy adult male New Zealand big-eared white rabbits,apply the random number table method,divided into normal control group(group A),model group(group B),shallow needling Neiguan(PC6)10 min group(group C),shallow needling Neiguan(PC6)20 min group(group D),shallow needling Neiguan(PC6)30 min group(group E),deep needling Neiguan(PC6)10 min group(group F),deep needling Neiguan(PC6)20 min group(group G),deep needling Neiguan(PC6)30 min group(group H),7 animals in each group.Electrocardiograms were used to collect the duration of arrhythmia;hematoxylin-eosin staining method was performed on myocardial tissue,RT-PCR tested the expression ofα1C subunit mRNA,and the activity of Ca^(2+)-Mg^(2+)-ATPase were quantified by phosphorus determination method.RESULTS:The duration of arrhythmia in each acupuncture treatment group was shortened to varying degrees.Compare to the model group,the tissue damage from barium chloride inducing was improved in the acupuncture group.Compared to the model group,except for group E,most treatment groups had varying degrees of improvement with significantly down-regulated L-type calcium channelα1C subunit mRNA expressions level and increased Ca^(2+)-Mg^(2+)-ATPase activity.CONCLUSIONS:The effect of acupuncture at Neiguan(PC6)with different depths and retention time can reduce the duration of arrhythmia induced by barium chloride relatively,improve the induced pathological changes,down regulate L-type calcium channelα1C subunit mRNA expressions level and increase Ca^(2+)-Mg^(2+)-ATPase activity.Both the shallow and deep tissues of Neiguan(PC6)may be involved in transmitting acupuncture information.There is an optimal induction period for shallow needling at Neiguan(PC6)to reach the best therapeutic effect. | GU Chunling CHENG Kai YANG Shouqin RAN Shaofeng TAI Hengyap GAO Xiaofeng PANG Dandan | 2021 | Journal of Traditional Chinese Medicine2021，41，6： | 1 |
| 3 | Novel confinement combustion method of nanosized WC/C for efficient electrocatalytic oxygen reduction显示文摘Nanosized tungsten carbide(WC)/carbon(C)catalyst was synthesized via a novel ultra-rapid confinement combustion synthesis method.The amount of activated carbon(AC)plays an important role in the morphology and structure,controlling both the precursor and final powder.The WC particles synthesized inside the pores of the AC had been 10-20 nm because of the confinement of the pore structure and the large specific surface area of AC.When used for oxygen reduction performance,the half-wave potential was−0.24 V,and the electron transfer number was 3.45,indicating the main reaction process was the transfer of four electrons.The detailed electrocatalytic performance and underlying mechanism were investigated in this work.Our study provides a novel approach for the design of catalysts with new compositions and new structures,which are significant for promoting the commercialization of fuel cells. | Pengqi Chen Yunxiao Tai Huan Wu Yufei Gao Jiayu Chen Jigui Cheng | 2022 | International Journal of Minerals,Metallurgy and Materials2022，29，8： | 1 |

| 5 | Taxoids from the Needles of Taxus×media Hicksii显示文摘A new taxane diterpenoid, named 7-deacetoxy taxinine J, together with ten knowncompounds were isolated from the needles of Taxus × media Hickiii. The structures of allcompounds were elucidated and identified by spectroscopic methods. T’he structure of 7-deacetoxytaxinine J was further confirmed by X-ray crystallographic analysis. The structure of the knowncompound, taxinine E, was also revised. | Yong Li GAO Jin Yun ZHOU Di An SUN Qi Cheng FANG Nan WU Yang LU Qi Tai ZHENG(Institute of Materia Medica, Chinese Academy of Medical Sciences andPeking Union Medical College, Beding 100050) | 1998 | Chinese Chemical Letters1998，9，12： | 0 |
