新型冠状病毒(SARS-CoV-2,简称新冠病毒)感染可对部分患者构成重大威胁。罹患血液系统恶性肿瘤及接受抗肿瘤治疗的患者均可出现免疫抑制状态,其感染新冠病毒后出现严重并发症的风险增加,重症发生率和死亡率明显增加。本文详述了1例滤泡型淋巴瘤患者感染新冠病毒后的治疗过程。该患者在入院治疗期间反复进行核酸检测(RT-PCR),结果显示持续阳性近90天,经过5轮抗病毒治疗及糖皮质激素抗炎、低分子肝素抗凝、抗生素抗感染治疗,并辅以呼吸机支持治疗等,最终患者核酸转阴,顺利脱机出院。本研究总结了该病例的救治过程,以期为临床诊治提供参考和经验。

目的:探究高强度聚焦超声(high intensity focused ultrasound,HIFU)治疗子宫腺肌病对卵巢储备能力的影响。方法:回顾性分析2019年5月至2020年12月在某院进行HIFU治疗的106例子宫腺肌病患者的临床资料。所有患者均行HIFU治疗,分别于治疗前和治疗6个月后行彩色多普勒超声检查,并获取阻力指数、搏动指数、血管化指数、血流指数、血管化血流指数及窦卵泡数目,检测血清抗苗勒氏管激素(anti-Müllerian hormone,AMH)、卵泡刺激素(folliclestimulating hormone,FSH)及黄体生成激素(luteinizing hormone,LH)水平,并分析血清AMH水平与FSH、LH水平的相关性。采用SPSS 21.0统计学软件进行数据分析。结果:与治疗前相比,治疗6个月后血清FSH、LH、FSH/LH值、阻力指数及搏动指数均显著降低,血管化指数、血流指数、血管化血流指数、窦卵泡数目及血清AMH水平均显著升高,差异有统计学意义(P<0.05)。治疗6个月后,血清AMH水平与FSH、LH水平均呈负相关(r=-0.448、-0.527,P<0.05)。结论:HIFU治疗能够降低性激素水平、提升血清AMH水平和窦卵泡数目,从而改善子宫腺肌病患者的卵巢储备能力。

Glycerol carbonate,an important glycerol value-added product,has been widely used as an active intermediate and inert solvent in the synthesis of cosmetics,detergents,chemical intermediates,polymers,and so *** direct carbonylation from glycerol with CO_(2)is considered a promising route,but still tough work due to the thermodynamic stability and the kinetic inertness of CO_(2).In this work,highlyselective direct carbonylation of glycerol and CO_(2)into glycerol carbonate has been achieved over highly dispersed MgInCe-mixed metal oxides(MgInCe-MMO),which were prepared through the topological transformation derived from the MgInCe-layered double hydroxides(MgInCe-LDHs).By precisely modulating the surface basic-acidic properties and the oxygen vacancies,an efficient carbonylation of glycerol with CO_(2)has been achieved with a selectivity of up to>99%to glycerol *** investigation into the synergistic catalysis of base-acid sites and oxygen vacancies has been clarified.

A method of designing broad angular phase retarders in the extreme ultraviolet （EUV） region is presented. The design is based on a standard Levenberg-Marquardt algorithm combined with a common merit function. Using this method, a series of broad angular EUV phase retarders were designed using aperiodic Mo/Si multilayers. At photon energy of 90 eV, broad angular phase retarders with 30°, 60°, and 90° phase retardations have been realized in the angular range of 39°-51°. By analyzing and comparing the performances of the designed broad angular phase retarders, we found that the Mo/Si multilayer with more layers could obtain higher phase retardation in broader angular range when used to design the broad angular phase retarder. Broad angular phase retarders possess lower sensitivity toward changing incident angle compared with the traditional phase retarders designed with transmission periodic multilayers, and can be used for the polarization control of broad angular EUV sources.

To accurately obtain the waveform template of gravitational waves, substantial computational resources and extremely high precision are often required. In a previous study, we employed the confluent Heun function to obtain an exact solution to the Teukolsky equation. This approach allowed us to efficiently and accurately calculate the gravitational wave flux for a particle in circular orbits around a Schwarzschild black hole. Building on this method, we now extend its application to calculate the asymptotic gravitational wave fluxes from a particle in generic orbits around a near-extreme Kerr black hole. Our extended method proves particularly effective in handling computational challenges associated with large eccentricities(e = 0.9), higher spins(a = 0.999), higher harmonic modes, and strong-field regions. The results we obtained significantly outperform those derived from the numerical integration method based on the Mano-Suzuki-Takasugi method.
