| 2 | Use of angiotensin-converting enzyme inhibitors and angiotensin Ⅱ receptor blockers in context of COVID-19 outbreak:a retrospective analysis显示文摘The possible effects of angiotensin-converting enzyme inhibitors(ACEIs)or angiotensin Ⅱ receptor blockers(ARBs)on COVID-19 disease severity have generated considerable debate.We performed a single-center,retrospective analysis of hospitalized adult COVID-19 patients in Wuhan,China,who had definite clinical outcome(dead or discharged)by February 15,2020.Patients on anti-hypertensive treatment with or without ACEI/ARB were compared on their clinical characteristics and outcomes.The medical records from 702 patients were screened.Among the 101 patients with a history of hypertension and taking at least one anti-hypertensive medication,40 patients were receiving ACEI/ARB as part of their regimen,and 61 patients were on antihypertensive medication other than ACEI/ARB.We observed no statistically significant differences in percentages of in-hospital mortality(28%vs.34%,P=0.46),ICU admission(20%vs.28%,P=0.37)or invasive mechanical ventilation(18%vs.26%,P=0.31)between patients with or without ACEI/ARB treatment.Further multivariable adjustment of age and gender did not provide evidence for a significant association between ACEI/ARB treatment and severe COVID-19 outcomes.Our findings confirm the lack of an association between chronic receipt of reninangiotensin system antagonists and severe outcomes of COVID-19.Patients should continue previous antihypertensive therapy until further evidence is available. | Jiuyang Xu Chaolin Huang Guohui Fan Zhibo Liu Lianhan Shang Fei Zhou Yeming Wang Jiapei Yu Luning Yang Ke Xie Zhisheng Huang Lixue Huang Xiaoying Gu Hui Li Yi Zhang Yimin Wang Frederick G.Hayden Peter W.Horby Bin Cao Chen Wang | 2020 | Frontiers of Medicine2020，14，5： | 2 |
| 3 | Method for measuring the steering wheel angle of paddy field agricultural machinery by integrating RTK-GNSS and dual-MEMS gyroscope显示文摘Aiming at the application environment of paddy agricultural machinery with bumpy and undulating changes,the problems affecting the method for steering wheel angle measurement by MEMS gyroscope were analyzed,and a wheel angle measurement method combining Dual-MEMS gyroscope(dual MEMS gyroscope)and RTK-GNSS was designed.The adaptive weighting method was used to fuse the heading angle differentiation of RTK-GNSS,the MEMS gyroscope angle rate,and velocity data,and the rod-arm compensation was performed to accurately obtain the angle rates of the body and steering wheels of agricultural machinery;the difference between the combined angular rate of the steering wheel of the agricultural machinery and the angular rate of the agricultural machinery body was obtained,and the integrator is used to integrate the difference to get the wheel steering angle value,and the Kalman filter was designed to make feedback correction for the integration process of angle calculation to eliminate the errors caused by the gyroscope zero bias,random drift,and gyroscope rod arm effect,and to obtain the accurate value of wheel steering angle.A comparative test with the connecting rod wheel angle sensor was designed,and the results show that the maximum deviation is 4.99°,the average absolute average value is 1.61°,and the average standard deviation is 0.98°.The method in this study and the connecting rod wheel angle sensor were used on paddy farm machinery.The wheel angle measurement deviation of the proposed method and the connecting rod wheel angle sensor was not more than 1°,which is relatively small.It has good stability,speed adaptability,and dynamic responsiveness that meets the accuracy requirements of steering wheel angle measurement for paddy field agricultural machinery unmanned driving and can be used instead of connecting rod angle sensors for unmanned agricultural machinery. | Pei Wang Lian Hu Jie He Siqi Ke Zhongxian Man Tuanpeng Tu Luning Yang Yuanyuan Li Yanling Yi Weicong Li Xiwen Luo | 2022 | International Journal of Agricultural and Biological Engineering2022，15，6： | 1 |

| 5 | Shen-Qi-Wan Protects the Renal Peritubular Capillary Injury from Adenine-mediated Damage by Upregulating Aquaporin 1显示文摘Background:Shen-Qi-Wan(SQW),a commonly used prescription against chronic kidney disease(CKD)in Tradi-tional Chinese Medicine(TCM),has a nephroprotective action in adenine-induced kidney injury.However,the mechanism of SQW in renal injury remains unclear.Objective:This study was undertaken to measure the effect of SQW on peritubular capillary injury both in vivo and in vitro assays.Methods:The effect of SQW on the peritubular capillary injury was evaluated according to measuring hypothalamic-pituitary-adrenal(HPA)function,inflammatory cytokines,VEGF(vascular endothelial growth fac-tor),CD34(Cluster of differentiation 34),and AQP1(Aquaporin 1)levels in the kidney,cell migration,and lumen forming capacity.Results:SQW supplementation could ameliorate dysfunction of the HPA and renal function loss induced by adenine.SQW also significantly inhibited the inflammatory cytokines including MCP-1(monocyte chemotactic protein-1)and VCAM-1(vascular cell adhesion molecule-1)level.Alternatively,SQW administration showed an ameliorating effect from the toxicity and alleviated the injury of capillaries around renal tubules instigated by adenine through increasing AQP1 mRNA and protein level.SQW medicated the serum enhanced the migration and lumen formation ability of HMEC-1 cells,and significantly increased AQP1 protein level.Moreover,AQP1 knockdown efficiently inhibited the migration and lumen formation ability in HMEC-1 cells,and weakened the effect of SQW medicated serum.Conclusion:These results suggested that SQW attenuated peritubular capillary injury in adenine-induced CKD model rats through boosting angiogenesis in endothelial cell,and AQP1 may be a potential target of SQW for treating the renal injury. | Yuting Bao Yehui Zhang Yuanxiao Yang Xueming Chen Luning Lin Yunbo Fu Liting Ji Changyu Li | 2022 | Clinical Complementary Medicine and Pharmacology2022，2，1： | 1 |

| 7 | Vapor Phase Polymerization Deposition Conducting Polymer Nanocomposites on Porous Dielectric Surface as High Performance Electrode Materials显示文摘We report chemical vapor phase polymerization(VPP) deposition of poly(3,4-ethylenedioxythiophene)(PEDOT) and PEDOT/graphene on porous dielectric tantalum pentoxide(Ta_2O_5) surface as cathode films for solid tantalum electrolyte capacitors. The modified oxidant/oxidant-graphene films were first deposited on Ta_2O_5 by dip-coating, and VPP process was subsequently utilized to transfer oxidant/oxidant-graphene into PEDOT/PEDOT-graphene films. The SEM images showed PEDOT/PEDOT-graphene films was successfully constructed on porous Ta_2O_5 surface through VPP deposition, and a solid tantalum electrolyte capacitor with conducting polymer-graphene nano-composites as cathode films was constructed. The high conductivity nature of PEDOT-graphene leads to resistance decrease of cathode films and lower contact resistance between PEDOT/graphene and carbon paste. This nano-composite cathode films based capacitor showed ultralow equivalent series resistance(ESR) ca. 12 m? and exhibited excellent capacitance-frequency performance, which can keep 82% of initial capacitance at 500 KHz. The investigation on leakage current revealed that the device encapsulation process has no influence on capacitor leakage current, indicating the excellent mechanical strength of PEDOT/PEDOT-gaphene films. This high conductivity and mechanical strength of graphene-based polymer films shows promising future for electrode materials such as capacitors, organic solar cells and electrochemical energy storage devices. | Ya jie Yang Luning Zhang Shibin Li Zhiming Wang Jianhua Xu Wenyao Yang Yadong Jiang | 2013 | Nano-Micro Letters2013，5，1： | 1 |
| 8 | N-doped carbon shell encapsulated PtZn intermetallic nanopartides as highly efficient catalysts for fuel cells显示文摘The high cost and poor durability of Pt nanoparticles(NPs)have always been great challenges to the commercialization of proton exchange membrane fuel cells(PEMFCs).Pt-based intermetallic NPs with a highly ordered structure are considered as promising catalysts for PEMFCs due to their high catalytic activity and stability.Here,we reported a facile method to synthesize N-doped carbon encapsulated PtZn intermetallic(PtZn@NC)NPs via the pyrolysis of Pt@Zn-based zeolitic imidazolate framework-8(Pt@ZIF-8)composites.The catalyst obtained at 800℃(10%-PtZn@NC-800)was found to exhibit a half-wave potential(Ev2)up to 0.912 V versus reversible hydrogen electrode(RHE)for the cathodic oxygen reduction reaction in an acidic medium,which shifted by 26 mV positively compared to the benchmark Pt/C catalyst.Besides,the mass activity and specific activity of 10%-PtZn@NC-800 at 0.9 V versus RHE were nearly 3 and 5 times as great as that of commercial Pt/C,respectively.It is worth noting that the PtZn@NC showed excel Ient stability in oxygen reducti on reacti on(ORR)with just 1 mV of the Ev2 loss after 5,000 cycles,which is superior to that of most reported PtM catalysts(especially those disordered solid solutions).Furthermore,such N-doped carb on shell encapsulated PtZn intermetallic NPs showed significa ntly enha need performances towards the anodic oxidation reaction of organic small molecules(such as methanol and formic acid).The synergistic effects of the N doped carbon encapsulation structure and intermetallic NPs are responsible for outstanding performances of the catalysts.This work provides us a new engineering strategy to acquire highly active and stable multifunctional catalysts for PEMFCs. | Yakun Xue Huiqi Li Xieweiyi Ye Shuangli Yang Zhiping Zheng Xiao Han Xibo Zhang Luning Chen Zhaoxiong Xie Qin Kuang Lansun Zheng | 2019 | Nano Research2019，12，10： | 0 |
| 9 | Characteristics of crustal variation and extensional break-up in the Western Pacific back-arc region based on a wide-angle seismic profile显示文摘The marginal sea and back-arc basins in the Western Pacific Ocean have become the focus of tectonics due to their unique tectonic location.To understand the deep crustal structure in the back-arc region,we present a 545-kmlong active-source ocean bottom seismometer(OBS)wide-angle reflection/refraction profile in the East China Sea.The P wave velocity model shows that the Moho depth rises significantly,from approximately 30 km in the East China Sea shelf to approximately 16 km in the axis of the Okinawa Trough.The lower crustal high-velocity zone(HVZ)in the southern Okinawa Trough,with V_(p) of 6.8-7.3 km/s,is a remarkable manifestation of the mantle material upwelling and accretion to the lower crust.This confirms that the lower crustal high-velocity mantle accretion is developed in the southern Okinawa Trough.During the process of back-arc extension,the crustal structure of the southern Okinawa Trough is completely invaded and penetrated by the upper mantle material in the axis region.In some areas of the southern central graben,the crust may has broken up and entered the initial stage of seafloor spreading.The discontinuous HVZs in the lower crust in the back-arc region also indicate the migration of spreading centers in the back-arc region since the Cenozoic.The asthenosphere material upwelling in the continent-ocean transition zone is constantly driving the lithosphere eastward for episodic extension,and is causing evident tectonic migration in the Western Pacific back-arc region. | Jianghao Qi Xunhua Zhang Zhiqiang Wu XiangjunMeng Luning Shang Yang Li Xingwei Guo Fanghui Hou Enyuan He QiangWang | 2021 | Geoscience Frontiers2021，12，3： | 0 |
