Chinese Medical Journal 2015年第11期128卷 1483-1489页

作者： yan xiao kun-qi yang yan-kun yang ya-xin liu tao tian lei song xiong-jing jiang xian-liang zhou Department of Cardiology State Key Laboratory of Cardiovascular Disease Fuwai Hospital National Center for Cardiovascular Disease Chinese Academy of Medical Sciences and Peking Union Medical College Beijing 100037 China

Background： End-stage hypertrophic cardiomyopathy （HCM） is complicated by substantial adverse events. However, few studies have focused on electrocardiographic features and their prognostic values in HCM. This study aimed to evaluate the clinical manifestations and prognostic value of electrocardiography in patients with end-stage HCM. Methods： End-stage HCM patients were enrolled from a total of 1844 consecutive HCM patients from April 2002 to November 2013 at Fuwai Hospital. Clinical data, including medical history, electrocardiography, and echocardiography, were analyzed. Cox hazards regression analysis was used to assess the risk factors for cardiovascular mortality. Results： End-stage HCM was identified in 99 （5.4%） patients, averaged at 52 ± 16 years old at entry. Atrial fibrillation was observed in 53 patients and mural thrombus in 19 patients. During 3.9 ±3.0 years of follow-up, embolic stroke, refractory heart failure, and death or transplantation were observed in 20, 39, and 51 patients, respectively. The incidence of annual mortality was 13.2%. Multivariate Cox hazards regression analysis identified New York Heart Association Class （NYHA） Ill/IV at entry （hazard ratio [HR]： 1.99; 95% confidence interval [C/I： 1.05-3.80; P = 0.036）, left bundle branch block （LBBB）（HR： 2.80; 95% CI： 1.47-5.31; P = 0.002）, and an abnormal Q wave （HR： 2.21; 95% CI： 1.16-4.23; P = 0.016） as independent predictors of cardiovascular death, in accordance with all-cause death and heart failure-related death. Conclusions： LBBB and an abnormal Q wave are risk factors of cardiovascular mortality in end-stage HCM and provide new evidence for early intervention. Susceptibility of end-stage HCM patients to mural thrombus and embolic events warrants further attention.

Objective Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains *** A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients’ medical records. Multivariable logistic regression models were used to estimate the odds ratio(OR) and 95% confidence interval(95% CI) of the associations between comorbidities(cardiometabolic or non-cardiometabolic diseases), clinical severity, and treatment outcomes of *** Overall, 158(13.6%) patients were diagnosed with severe illness and 32(2.7%) had unfavorable outcomes. Hypertension(2.87, 1.30–6.32), type 2 diabetes(T2 DM)(3.57, 2.32–5.49),cardiovascular disease(CVD)(3.78, 1.81–7.89), fatty liver disease(7.53, 1.96–28.96), hyperlipidemia(2.15, 1.26–3.67), other lung diseases(6.00, 3.01–11.96), and electrolyte imbalance(10.40, 3.00–26.10)were independently linked to increased odds of being severely ill. T2 DM(6.07, 2.89–12.75), CVD(8.47,6.03–11.89), and electrolyte imbalance(19.44, 11.47–32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission(5.46,3.25–9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes(6.58, 1.46–29.64) within two *** Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome.

The Large sky Area Multi-Object Fiber Spectroscopic Telescope（LAMOST） general survey is a spectroscopic survey that will eventually cover approximately half of the celestial sphere and collect 10 million spectra of stars, galaxies and QSOs. Objects in both the pilot survey and the first year regular survey are included in the LAMOST DR1. The pilot survey started in October 2011 and ended in June 2012, and the data have been released to the public as the LAMOST Pilot Data Release in August 2012. The regular survey started in September 2012, and completed its first year of operation in June 2013. The LAMOST DR1 includes a total of 1202 plates containing 2 955 336 spectra, of which 1 790 879 spectra have observed signalto-noise ratio（SNR） ≥ 10. All data with SNR ≥ 2 are formally released as LAMOST DR1 under the LAMOST data policy. This data release contains a total of 2 204 696 spectra, of which 1 944 329 are stellar spectra, 12 082 are galaxy spectra and 5017 are quasars. The DR1 not only includes spectra, but also three stellar catalogs with measured parameters： late A,FGK-type stars with high quality spectra（1 061 918 entries）, A-type stars（100 073 entries）, and M-type stars（121 522 entries）. This paper introduces the survey design, the observational and instrumental limitations, data reduction and analysis, and some caveats. A description of the FITS structure of spectral files and parameter catalogs is also provided.

We present the observational results from a detailed timing analysis of the black hole candidate EXO 1846-031 during its outburst in 2019 with the observations of Insight-HXMT,NICER and *** outburst can be classified roughly into four different ***-C quasi-periodic oscillations(QPOs)observed by NICER(about 0.1-6 Hz)and Insight-HXMT(about 0.7-8 Hz)are also reported in this ***,we study various physical quantities related to QPO *** QPO rms-frequency relationship in the energy band 1-10 keV indicates that there is a turning pointing in frequency around2 Hz,which is similar to that of GRS 1915+105.A possible hypothesis for the relationship above may be related to the inclination of the source,which may require a high inclination to explain *** relationships between QPO frequency and QPO rms,hardness,total fractional rms and count rate have also been found in other transient sources,which can indicate that the origin of type-C QPOs is non-thermal.

在基于白光中子源的中子核反应测量中,伴随中子束的伽马射线是重要的实验本底之一.本文对中国散裂中子源反角白光中子源的束内伽马射线进行了研究.通过蒙特卡罗模拟,得到了伽马射线的能量分布和时间结构.通过直接测量和间接测量两种方法测得低能中子区的束内伽马射线的时间结构.直接测量实验中,将载6Li的ZnS(Ag)闪烁体探测器置于束流线上,通过飞行时间法直接测量束内的中子和伽马射线的时间结构,并利用波形甄别技术进行粒子鉴别.间接测量法是将铅样品置于束流线上,利用C6D6闪烁体探测器测量样品上的散射伽马射线,从而得到入射伽马射线的时间结构.实验测量结果与模拟结果在12μs—2.0 ms的时间区间内具有较好的一致性.

目前国内外的质子标定终端较少,且普遍为单能质子束流.基于中国散裂中子源的反角白光中子源的eV—200 MeV中子能量区间的白光中子束流,以及中子与氢的~1H(n, el)反应,可以获得宽能谱的能量连续次级质子.利用1 GSps采样率、12 bit的波形数字化获取系统采集探测器输出波形信号,通过对波形信号的分析,得到中子及反冲质子的飞行时间,进而得到反冲质子的动能.利用该方法得到的质子,为探测器质子标定等研究提供了新的研究平台.在该研究平台已经开展了带电粒子望远镜的标定实验.研究了CsI (Tl)探测器不同的信号读出方式对望远镜的DE-E二维谱、幅度-质子动能二维谱等粒子鉴别方法得到的粒子鉴别的效果,得到了较优的探测器信号读出方案.该研究为带电粒子望远镜的建设提供了实验依据,也说明了基于反角白光中子源的宽能谱质子标定的可行性.
