| 1 | Diagnostic and prognostic value of minor elevated cardiac troponin levels for percutaneous coronary intervention-related myocardial injury:a prospective,single-center and double-blind study显示文摘Cardiac troponin-I(cTnI) and-T(cTnT) are sensitive and specific markers of myocardial injury.However,the role of increased cTnI and cTnT in percutaneous coronary intervention(PCI)-related myocardial injury remains controversial.In this prospective,single-center and double-blind study,we aimed to determine the diagnostic and prognostic value of cTnI as well as cTnT(cTns) in PCI-related myocardial injury in a Chinese population.A total of 1,008 patients with stable angina pectoris and non-ST-segment elevation acute coronary syndrome were recruited.The levels of cTnI and cTnT were examined before and after PCI.All patients were followed up for26±9 months to observe the incidence of major adverse cardiac events(MACEs).Our results showed that postPCI cTnI and/or cTnT levels were increased to more than the 99^(th) percentile upper reference limit(URL) in 133(13.2%) patients,among which 22(2.2%) were more than 5×99^(th) percentile URL.By univariate analysis,an elevation in cTns after PCI was not an independent predictor of increased MACEs,HR 1.35(P = 0.33,95%CI:0.74-2.46).In conclusion,our data demonstrate that the incidence of PCI-related myocardial injury is not common in a Chinese population and minor elevated cTns levels may not be a sensitive prognostic marker for MACEs. | Min Zhang Huiwei He Ze-Mu Wang Zhihui Xu Ningtian Zhou Zhengxian Tao Bo Chen Chunjian Li Tiebing Zhu Di Yang Liansheng Wang Zhijian Yang | 2014 | The Journal of Biomedical Research2014，28，2： | 12 |
| 2 | A survey on distributed optimisation approaches and applications in smart grids显示文摘Smart grid and smart metering technologies are transforming the utility industry and the customer experience in search of a new energy deal that supports a more collaborative,eco-friendly,stable,reliable and cost-efficient system as a whole.In order to unlock the full benefits,utilities need now to develop new technologies like distributed optimisation methods to excavate the latent value from the magnanimous data.This paper surveys recent advances of distributed optimisation and game algorithms with applications in power systems.In particular,this paper reviews distributed algorithms for model-based offline optimisation solution of dynamic economic dispatch problems,charging control problems for plug-in electric vehicles and risk-averse energy trading as well as model-free online algorithms for demand response problems. | Huiwei Wang Chaojie Li Jueyou Li Xing He Tingwen Huang | 2019 | Journal of Control and Decision2019，6，1： | 2 |
| 3 | Combustion Characteristics of Coal Mine Methane in a Preheated-Burner Packed with Raschig Rings显示文摘The utilization of coal mine methane(CMM)through porous medium combustion(PMC)contributes to energy saving and environmental protection.In this paper,a double-layer porous medium burner with the combination of heat exchangers was designed to recycle the exhausted heat for preheating the inlet gas.The effects of Raschig ring sizes on the temperature distributions and pollutant emissions were studied under different operating conditions.The results indicate that the preheating of inlet gas greatly influenced the temperature distribution and the optimum preheating effect was shown in the burner of spiral heat exchanger together with lower pollutant emissions.With the increasing of inlet velocity and equivalence ratio,the peak temperature was increased significantly.As the Raschig ring size increased,the flame temperature increased first and then decreased gradually.Meanwhile,the highest temperature and lowest average emissions of NOx and CO appeared in the burner of 10 mm Raschig rings.This study will provide the CMM utilization engineering with the theoretical foundation on PMC. | DAI Huaming ZHU Huiwei YANG Pan DAI Hongchao HE Song WANG Zhiqiang | 2021 | Journal of Thermal Science2021，30，5： | 0 |
