目的分析脑卒中后偏瘫患者吞咽功能与膈肌运动的相关性。方法采用标准吞咽功能评价量表(SSA)评估51例脑卒中后偏瘫患者的吞咽功能。其中,吞咽障碍31例(吞咽障碍组),非吞咽障碍20例(非吞咽障碍组)。采用超声测定膈肌功能,分析SSA评分与膈肌运动的相关性。结果吞咽障碍组患侧膈肌活动度、呼气末膈肌厚度、膈肌增厚率低于非吞咽障碍组(P<0.05)。吞咽障碍组SSA评分与患侧膈肌活动度、呼气末膈肌厚度和膈肌增厚率呈负相关(r=-0.72、-0.67和-0.55,P<0.05)。结论脑卒中后偏瘫患者吞咽功能可能与膈肌运动密切相关,患侧膈肌活动度越差,吞咽功能越差。

Revisiting the mechanisms of mid-Tertiary uplift of the NE Tibetan Plateau

引用

National Science Review 2023年第4期10卷 169-190页

作者： hong-hong Wei Guo-Li Wu Lin Ding Long-Gang Fan Lin Li Qing-Ren Meng State Key Laboratory of Tibetan Plateau Earth System Environment and Resources (TPESER) Institute of Tibetan Plateau Research Chinese Academy of Sciences Institute of Geomechanics Chinese Academy of Geological Sciences State Key Laboratory of Lithospheric Evolution Institute of Geology and Geophysics Chinese Academy of Sciences Department of Geosciences University of Arizona University of Chinese Academy of Sciences

Contrasting views exist on timing and mechanisms of Tertiary crustal uplift in the NE Tibetan Plateau based on different approaches, with many models atributing surface uplift to crustal shortening. We carry out a comprehensive investigation of mid-Tertiary stratigraphy, sedimentology, and volcanism in the West Qinling, Hoh Xil and Qaidam basin, and the results challenge previous views. It was held that the discordance between Oligocene and Miocene strata is an angular unconformity in the West Qinling, but our field observations show that it is actually a disconformity, indicative of vertical crustal uplifting rather than crustal shortening at the Oligocene to Miocene transition. Widespread occurrence of synsedimentary normal faults in mid-Tertiary successions implicates supracrustal stretching. Miocene potassic–ultrapassic and mafic–ultramafic volcanics in the Hoh Xil and West Qinling suggest a crucial role of deep thermomechanical processes in generating crust-and mantle-sourced magmatism. Also noticeable are the continuity of mid-Tertiary successions and absence of volcanics in the Qaidam basin. Based on a holistic assessment of stratigraphic–sedimentary processes, volcanic petrogenesis, and spatial variations of lithospheric thicknesses, we speculate that small-sale mantle convection might have been operating beneath northeast Tibet in the mid-Tertiary. It is assumed that northward asthenospheric flow was impeded by thicker cratonic lithosphere of the Qaidam and Alxa blocks, thereby leading to edge convection. The edge-driven convection could bring about surface uplift, induce supracrustal stretching, and trigger vigorous volcanism in the Hoh Xil and West Qinling in the mid-Tertiary period. This mechanism satisfactorily explains many key geologic phenomena that are hardly reconciled by previous models.

中国MET异常非小细胞肺癌临床诊疗现状调研

循证医学 2024年第2期24卷 97-106页

作者：甘彬刘思阳严红虹吴一龙广东省肺癌研究所南方医科大学附属广东省人民医院(广东省医学科学院)广州510080 暨南大学附属第一医院血液科广州510630

目的非小细胞肺癌(non-small cell lung cancer,NSCLC)中间充质上皮转化因子(mesenchymal epithelial transition factor,MET)异常主要包括MET基因第14号外显子(MET exon 14)跳跃突变(简称METex14跳突)、MET基因扩增及MET蛋白过表达等。METex14跳突是NSCLC的原发致癌驱动变异,在NSCLC患者中的发生率约为0.9%~4%,目前国内外已有多个针对METex14跳突的靶向药物获批上市。NSCLC中原发MET基因扩增发生率约为1%~5%,与不良预后相关。MET基因扩增更常继发于其他驱动基因阳性NSCLC患者靶向治疗后,是表皮生长因子受体酪氨酸激酶抑制剂(epidermal growth factor receptor-tyrosine kinase inhibitor,EGFR-TKI)耐药的重要机制之一。本调研旨在了解国内MET异常NSCLC患者的诊疗现状、受访医师对MET抑制剂的认知、对于MET异常NSCLC患者治疗决策的考量,同时探求临床实践中未被满足的需求。方法限定时间内诊治过MET异常的医师通过在线问卷形式参与调研,并对结果进行汇总和描述性分析。结果调研共回收140份有效问卷。对于METex14跳突NSCLC,无论初治还是经治,超过50%的受访医师首选MET-TKI单药治疗。≥3级不良事件发生率是最为关注的安全性指标,最关注的不良反应有肺炎、肝毒性和胃肠道不良反应等,对于MET-TKI导致的外周水肿关注度不高。对于EGFR-TKI耐药后MET扩增NSCLC,受访医师首选MET-TKI和EGFR-TKI双靶联合的治疗方案。大型随机对照研究更充分证据、检测有待规范和临床共识是EGFR-TKI耐药后MET扩增NSCLC主要的未被满足的需求。结论MET-TKI在METex14跳突NSCLC的首选比例仍有待提升,对于METTKI导致的外周水肿的关注度需提高以帮助更科学地进行管理。针对不同类型的MET变异的检测还需进一步标准化和规范化。

The transcription factor NAC102 confers cadmium tolerance by regulating WAKL11 expression and cell wall pectin metabolism in Arabidopsis

引用

Journal of Integrative Plant Biology 2023年第10期65卷 2262-2278页

Cadmium(Cd) toxicity severely limits plant growth and development. Moreover, Cd accumulation in vegetables, fruits, and food crops poses health risks to animals and humans. Although the root cell wall has been implicated in Cd stress in plants, whether Cd binding by cell wall polysaccharides contributes to tolerance remains controversial, and the mechanism underlying transcriptional regulation of cell wall polysaccharide biosynthesis in response to Cd stress is unknown. Here, we functionally characterized an Arabidopsis thaliana NAC-type transcription factor, NAC102, revealing its role in Cd stress responses. Cd stress rapidly induced accumulation of NAC102.1, the major transcript encoding functional NAC102, especially in the root apex. Compared to wild type(WT) plants, a nac102 mutant exhibited enhanced Cd sensitivity, whereas NAC102.1-overexpressing plants displayed the opposite phenotype. Furthermore, NAC102 localizes to the nucleus, binds directly to the promoter of WALL-ASSOCIATED KINASE-LIKE PROTEIN11(WAKL11), and induces transcription, thereby facilitating pectin degradation and decreasing Cd binding by pectin. Moreover, WAKL11 overexpression restored Cd tolerance in nac102mutants to the WT levels, which was correlated with a lower pectin content and lower levels of pectin-bound Cd. Taken together, our work shows that the NAC102-WAKL11 module regulates cell wall pectin metabolism and Cd binding, thus conferring Cd tolerance in Arabidopsis.
