Based on the surface temperature measured by the infrared camera on the experimental advanced superconducting tokamak （EAST）, the heat fluxes on the lower outer divertor target plate during H-mode with the lower-hybrid wave current drive （LHCD） only and with the LHCD combined with the neutral beam injection （NBI） are calculated by the DFLUX code and compared. The analyzed discharges are lower single null divertor configuration discharges. In the case with the LHCD only （Ip ~ 400kA, PLHCD ~ 2 MW）, ELM-free appears after L-H transition with the peak heat flux on the lower outer target plate less than 1 MW/m2. However, there is no ELM- free appearing after the L-H transition in the case with the LHCD＋NBI （Ip ~ 300 kA, PLHCD ＋ PNBI ~ 2 MW）. The results show that the peak heat fluxes on the lower outer target plate in the LHCD＋NBI H-mode cases are larger than those in the LHCD H-mode under the similar auxiliary heating power. This is because the heat flux profiles of the lower outer target plate as a function of plate location in ELMing with the LHCD＋NBI are narrower than those with the LHCD only. The results are consistent with the results in terms of the scrape-off layer width observed in the EAST.

In the presence of Rh（COD）（dppe）Cl （COD=1, 5-cyclootadiene, dppe=1,2-bis-（diphenylphosphino）ethane） and CO, we studied the H/Cl exchange reaction between CH4 and o-dichlorobenzene, and observed that the active species of the reaction is a complex containing dppe and carbonyl ligands. We suggest that the mechanism of exchange reaction may be described by the elementary reaction of oxidative addition and reductive elimination. In the presence of trans-PtHL2X （L=PEt3, P（n-Pr）3, P（n-Bu）3, PPh3; X=Cl-, Br-, I-, CN-） complexes, we have studied the oxidative chlorination reaction of methane. The catalytic activity was found to be related to the electron-donating properties and the cone angle of tertiary phosphine, as well as the trans-effect of X anionic ligands. In addition to the above reactions, we have also studied the insertion reaction of acetylene into C-H bond of methane catalyzed by organotransition-metal complexes containing heterocyclic chelate ligands, such as bipy, phen and TMEDA, in

目的:本研究探讨基于高分辨率CT(HRCT)密度阈值法、密度直方图法和综合分析法的不同肺定量评估方法对结缔组织病(CTD)相关间质性肺疾病(ILD)患者严重程度的诊断能力和评估价值。方法:对连续接受HRCT胸部扫描和肺功能检查(PFT)的CTD-ILD患者进行回顾性分析。两位放射科医生使用Goh评分在HRCT上对ILD严重程度进行视觉半定量评分,并通过20%的Goh评分阈值和70%的用力肺活量(FVC%)阈值对ILD的严重程度进行分组(局限性组/弥漫性组)。记录基于HRCT密度阈值法与密度直方图法的定量指标并通过主成分分析法计算新指标-计算机综合化指数(CII)。采用t检验或Mann-Whitney U检验分析局限性/弥漫性组间各参数差异,使用单因素方差分析(ANOVA)或Kruskal-Wallis H检验比较不同CTD类型之间各参数的差异,使用Spearman相关分析评价各变量间的相关关系,采用受试者操作特征(ROC)曲线分析不同肺定量评估方法区分CTD-ILD严重程度的能力。结果:93例患者纳入研究,其中局限性组42例(45.16%),弥漫性组51例(54.84%)。结果表明,局限性组与弥漫性组间HRCT定量指标、视觉半定量评分及PFT参数差异均具有统计学意义(P<0.05),除MLA-4与DLCO%外,HRCT定量指标、视觉半定量评分及PFT参数之间存在显著相关性。ROC分析显示CII-4和CII-5对CTD-ILD严重程度的区分能力最强,AUC分别为0.886(95%CI:0.813~0.959)、0.883(95%CI:0.807~0.958)。结论:HRCT密度阈值法、密度直方图法和综合分析法等定量方法为评估CTD-ILD患者肺功能损害严重程度提供了客观指标,对区分预后较差的弥漫性CTD-ILD患者有潜在的重要意义,可作为视觉半定量评分有潜力的替代方法。

Enhancing the concentration of exogenous molecular drugs within the tumor microenvironment through enzyme-catalyzed polymerization presents a novel strategy for cancer therapy. Nonetheless, the optimization of the catalytic efficiency is often impeded by the inefficient expression of enzymes. Herein, we reported a self-amplifying fluorescent molecular probe, Bis-HTPICG, for photodynamic therapy(PDT) and subsequent PDT-induced immunoreaction. The Bis-HTP-ICG probe possesses a noticeable enzyme-catalyzed polymerization facilitated by myeloperoxidase(MPO), a crucial enzyme secreted by neutrophils at inflammation sites. Upon exposure to laser irradiation, Bis-HTP-ICG showed a high PDT efficacy, inducing an acute inflammatory response that stimulates further recruitment of neutrophils and then elevated MPO secretion. The heightened level of MPO enhances the accumulation of the Bis-HTP-ICG via self-polymerization or binding with intratumoral proteins following MPO enzyme catalysis, instigating a self-amplifying chain reaction cycle involving Bis-HTP-ICG, neutrophils and ***, PDT efficiently incites immunogenic cell death(ICD) in tumor cells, initiating an anti-tumor immune response including dendritic cells(DCs) maturation, T cell proliferation and reprogramming of tumor-associated neutrophils(TANs). This work portrays a promising strategy for self-amplification of fluorescent molecular probes through adjustable enzyme levels,potentially offering a unique avenue to enhance the tumor accumulation of molecular drugs for improved tumor therapy.
