Na3V2（PO4）2O2F （VP） is recognized as a promising cathode material for sodium-ion batteries due to its stable structural framework and high specific *** functional theory （DFT） and finite element simulations show that incorporating SO42-into VP decreases its band gap,lowers the migration energy barrier,and ensures a uniform Na+concentration gradient and stress distribution during charge and discharge ***,the average Na+diffusion coefficient of Na3V2（PO4）1.95（SO4）0.05O2F（VPS-1） is roughly double that of VP,leading to enhanced rate capability (80 C,75.5 mAh g-1) and cycling stability (111.0 mAh g-1capacity after 1000 cycles at 10 C current density) for ***-1 exhibits outstanding fast-charging capabilities,achieving an 80%state of charge in just 8.1 *** assembled VPS-1//SbSn/NPC full cell demonstrated stable cycling over 200 cycles at a high 5 C current,maintaining an average coulombic efficiency of 95.35%.

Peroxynitrite（ONOO-） is a highly reactive nitrogen species that plays pivotal roles in cell signal transduction and physiological or pathological progresses. However, commonly used ONOO-optical imaging probes are still hampered by high background/autofluorescence（fluorescence probe）, short emission wavelength, or poor selectivity in the case of chemiluminescence. Herein,we report a facile method to prepare an activatable chemiluminescence probe（PPA-PEG） with good biocompatibility and functionality for in vivo autofluorescence-free imaging of ONOO-. The PPA-PEG consists of pyropheophorbide-a（PPA）, a typical deep red photosensitizer that acts as both the recognition and signaling element, and 4-arm poly（ethylene glycol）(4-arm PEG), which improves the biosafety and water solubility of probe. These components can self-assemble into nanoparticles（namely PPA-PEG nanoprobe） in aqueous solution. The PPA-PEG nanoprobe showed an ultra-low chemiluminescence signal before interacting with ONOO-, but exhibited good selectivity, high sensitivity and a fast response toward ONOO-. The PPAPEG was successfully applied to image cellular ONOO-changes, as well as the endogenous ONOO-changes in inflammation models and subcutaneous or orthotopic hepatocellular carcinoma（HCC） tumors models in living mice. In vitro and in vivo studies verified the good detection and imaging capabilities of PPA-PEG for peroxynitrite, demonstrating suitable tissue penetration and a high signal-to-background ratio（SBR）. Thus, our nanoprobe can serve as a valuable activatable chemiluminescence imaging tool for studying important peroxynitrite-related chemical and biological applications.

目的：探讨2型糖尿病（ type 2 diabetes mellitus, T2DM）患者血糖控制与肱踝脉搏波传导速度（ brachial-ankle pulse wave velocity, baPWV）的关系。方法：采用横断面研究设计,对北京市某社区40岁及以上的T2DM患者及非患者进行问卷调查、体格检查、糖化血红蛋白（ glycated hemoglobin, HbA1c）及血脂等实验室指标检测、baPWV测量。根据HbA1c结果将患者分为血糖控制良好组和血糖控制不良组,分析血糖控制情况与baPWV之间的相关性。结果：共纳入1341名研究对象,包括733名T2DM患者及608名非患者。与非患者相比,T2DM患者中baPWV异常（baPWV≥1700 cm/s）率较高（40.8% vs.26.8%, P〈0.001）。分别以HbA1c〈6.5%和HbA1c〈7.0%为血糖控制目标时,非患者、血糖控制良好的T2DM患者组、血糖控制不良的T2DM患者组之间的baPWV异常率差异有统计学意义（non-diabetes vs. HbA1c〈6.5% T2DM vs. HbA1c≥6.5% T2DM：26.8% vs.32.8% vs.42.6%,P〈0.001；non-diabetes vs. HbA1c〈7.0% T2DM vs. HbA1c≥7.0% T2DM：26.8% vs.36.0% vs.43.4%,P〈0.001）。控制性别、年龄、吸烟、糖尿病家族史、2型糖尿病病程、心血管疾病史、腰臀比、收缩压、舒张压、总甘油三酯、高密度脂蛋白胆固醇、低密度脂蛋白胆固醇等因素后进行多重Logistic回归分析,结果显示与非糖尿病人群相比,HbA1c〈6.5%的糖尿病患者baPWV异常的OR值为0.927（95%CI 0.560～1.537）,HbA1c≥6.5%的糖尿病患者baPWV异常的OR值为1.826（95%CI 1.287～2.591）；与非糖尿病人群相比,HbA1c〈7.0%的糖尿病患者OR值为1.210（95%CI 0.808～1.811）,HbA1c≥7.0%的糖尿病患者baPWV异常的OR值为1.898（95%CI 1.313～2.745）。结论：社区2型糖尿病患者血糖控制情况与baPWV间存在显著的关联关系,血糖控制不良是baPWV异常的危险因素,良好控制血糖可能能够降低糖尿病患者发生心血管疾病的风险。
