Background:Pulmonary arterial hypertension(PAH)is characterized by excessive proliferation of small pulmonary arterial vascular smooth muscle cells(PASMCs),endothelial dysfunction,and extracellular matrix remodeling.G protein-coupled receptor kinase 2(GRK2)plays an important role in the maintenance of vascular tone and blood ***,the role of GRK2 in the pathogenesis of PAH is ***:GRK2 levels were detected in lung tissues from healthy people and PAH patients.C57BL/6 mice,vascular smooth muscle cell-specific Grk2-knockout mice(Grk2^(∆SM22)),and littermate controls(Grk2^(flox/flox))were grouped into control and hypoxia mice(n=8).Pulmonary hypertension(PH)was induced by exposure to chronic hypoxia(10%)combined with injection of the SU5416(cHx/SU).The expression levels of GRK2 and Yes-associated protein(YAP)in pulmonary arteries and PASMCs were detected by Western blotting and immunofluorescence *** mRNA expression levels of Grk2 and Yes-associated protein(YAP)in PASMCs were quantified with real-time polymerase chain reaction(RT-PCR).Wound-healing assay,3-(4,5)-dimethylthiahiazo(-z-y1)-3,5-di-phenytetrazoliumromide(MTT)assay,and 5-Ethynyl-2′-deoxyuridine(EdU)staining were performed to evaluate the proliferation and migration of ***,the interaction among proteins was detected by immunoprecipitation ***:The expression levels of GRK2 were upregulated in the pulmonary arteries of patients with PAH and the lungs of PH ***,cHx/SU-induced PH was attenuated in Grk2^(∆SM22) mice compared with littermate *** amelioration of PH in Grk2^(∆SM22) mice was accompanied by reduced pulmonary vascular *** vitro study further confirmed that GRK2 knock-down significantly altered hypoxia-induced PASMCs proliferation and migration,whereas this effect was severely intensified by overexpression of *** also identified that GRK2 promoted YAP expression and nuclear translocation in PASMCs,resulting in excessive PA

【目的】MAX2能抑制植物的分枝,且是独角金内酯信号传导途径的关键调控因子。MAX2同时还参与多种激素间的交叉互作,在植物抵御生物和非生物胁迫中发挥至关重要的作用。前期研究发现胡杨PeMAX2能调控拟南芥的离子平衡和耐盐性,但对于PeMAX2的耐旱功能还知之甚少,本文将探索胡杨PeMAX2调控拟南芥耐旱性的作用机制。【方法】将胡杨PeMAX2在拟南芥中异源表达,进行渗透胁迫和干旱胁迫,研究过表达PeMAX2拟南芥的生理和分子响应机制。【结果】(1)在长期干旱胁迫下,胡杨叶片PeMAX2基因表达水平升高。(2)甘露醇处理后,PeMAX2转基因拟南芥的种子萌发率和根长均高于野生型拟南芥(WT)和max2突变体,并且转基因株系细胞膜受损较轻。渗透胁迫后,转基因株系超氧化歧化酶、过氧化物酶、过氧化氢酶活性及其编码基因上调表达的升高幅度均显著高于拟南芥WT和max2突变体,转基因株系调控根细胞H_(2)O_(2)水平的能力更强。(3)土壤干旱处理10 d后,转基因株系叶绿素含量下降幅度低于WT和max2突变体,而且过表达株系在干旱胁迫下能维持较高水平的PSⅡ最大光化学效率、相对电子传递效率和实际光合量子产量;在碳同化和气孔导度方面,转基因拟南芥叶片的净光合速率和气孔导度均高于WT和突变体,说明过表达PeMAX2提高了拟南芥转基因植株在干旱条件下光合作用的能力。土壤复水后WT和突变体叶绿素含量、荧光和光合作用的恢复程度也明显低于转基因株系。【结论】过表达胡杨PeMAX2可以提高拟南芥的耐旱性,主要是由于过表达Pe MAX2提高了转基因拟南芥活性氧平衡的调控能力,减弱了干旱胁迫对生物膜的氧化损伤和光合作用的抑制。

目的评估血管内超声(IVUS)指导药物洗脱支架(DES)置入对急性冠脉综合征(ACS)患者长期临床结局的影响。方法研究对象来源于ULTIMATE研究,该研究是一项前瞻性、多中心、随机对照研究,于2014年8月—2017年5月在国内8家医院入选1448例置入DES的冠心病患者。本研究为ULTIMATE研究的亚组分析,将冠心病患者分为ACS组和非ACS组,2组患者均在IVUS或冠状动脉造影指导下置入DES。主要终点是术后3年靶血管失败(TVF)率,包含心原性死亡、靶血管心肌梗死和临床驱动的靶血管血运重建。结果1448例冠心病患者中,ACS组1136例(78.5%),1423例(98.3%)患者完成术后3年随访。ACS组患者术后3年的TVF发生率为9.6%(109/1136),高于非ACS组的4.5%(14/312),log-rankP=0.005。ACS组中IVUS指导下置入DES者的TVF发生率低于冠状动脉造影指导下置入DES架者[7.6%(43/569)比11.6%(66/567),log-rankP=0.019]。ACS组中IVUS指导下DES置入达标组患者术后3年的TVF发生率为5.4%(16/296),低于IVUS未达标组的9.9%(27/273),log-rankP=0.041。结论ACS患者置入DES后3年的TVF事件率高于无ACS患者;相比于冠状动脉造影,IVUS指导DES置入可以降低ACS患者术后3年的TVF事件,尤其是IVUS指导下DES置入达标的患者获益更明显。

Photonics Research 2024年第1期12卷 40-50页

作者： YUAN SHEN XIAOQIAN SHU LINGMEI MA shaoliang YU GENGXIN chen LIU LIU RENYOU GE BIGENG chen YUNJIANG RAO Research Center for Optical Fiber Sensing Zhejiang LaboratoryHangzhou 311100China Research Center for Intelligent Optoelectronic Computing Zhejiang LaboratoryHangzhou 311100China International Research Center for Advanced Photonics College of Optical Science and EngineeringZhejiang UniversityHangzhou 310058China Fiber Optics Research Center(FORC) Key Laboratory of Optical Fiber Sensing and CommunicationsUniversity of Electronic Science and Technology of ChinaChengdu 611731China

We experimentally demonstrate ultra-high extinction ratio(ER)optical pulse modulation with an electro-optical modulator(EOM)on thin film lithium niobate(TFLN)and its application for fiber optic distributed acoustic sensing(DAS).An interface carrier effect leading to a relaxation-tail response of TFLN EOM is discovered,which can be well addressed by a small compensation component following the main driving *** ultrahigh ER>50 dB is achieved by canceling out the tailed response during pulse modulation using the EOM based on a cascaded Mach–Zehnder interferometer(MZI)*** modulated optical_(√)pulses are then utilized as a probe light for a DAS system,showing a sensitivity up to-62.9 dB·rad∕Hz~2(7 pε/Hz)for 2-km single-mode sensing *** crosstalk suppression of 24.9 dB along the fiber is also obtained when the ER is improved from 20 dB to 50 dB,clearly revealing its importance to the sensing performance.
