Open Journal of Modern Neurosurgery 2024年第1期14卷 64-71页

Cervical myelopathy is a consequence of spinal cord compression in the cervical spine. Degenerative cervical spondylosis, osteophytes, discosteophyte complex, degenerative spondylolisthesis and hypertrophy of ligamentum flavum are the main etiologies of cervical myelopathy. Metastasis to cervical spine could be a rare cause of cervical myelopathy. The present study is a case report;presented a 36-year-old male with severe pain in cervical region, gait disability and impairment in sensory and motor function of upper left extremity. The patient had a history of thyroidectomy and cervical lymph node dissection due to follicular thyroid carcinoma (FTC) with improper follow-ups. He was diagnosed with metastatic cervical myelopathy and underwent surgical treatment. Cervical myelopathy due to metastasis is a rare condition and only few cases have been reported so far. So myelopathies can be a complication of metastatic cancers, and it should be considered by health professionals.

采用十二烷基硫酸钠(SDS)表面活性剂和SiO_(2)纳米颗粒作为发泡体系,在不同原油沥青质含量下进行泡沫稳定性实验,测量CO_(2)泡沫半衰期;采用扫描电子显微图像、紫外分光光度法测试和Zeta电位测量,分析沥青质降低CO_(2)泡沫稳定性的机理。研究表明:当合成油与发泡体系质量比为1∶9时,合成油沥青质质量分数从0增至15%,SDS稳定泡沫半衰期从751 s减少至239 s,SDS-SiO_(2)稳定泡沫半衰期从912 s缩短至298 s;当合成油与发泡体系质量比为2∶8时,随着沥青质质量分数增大,SDS稳定泡沫半衰期从526 s缩短至171 s,SDS-SiO_(2)稳定泡沫半衰期从660 s缩短至205 s。由于沥青质与SDS和SiO_(2)纳米颗粒在水相中的相互作用,Zeta电位绝对值减小,颗粒表面电荷降低,导致薄液膜两侧界面之间的排斥力减小,从而破坏泡沫稳定性。

微生物介导砷甲基化是砷生物地球化学循环中的重要过程.已有研究表明,腐殖质添加能促进稻田土壤厌氧微生物砷甲基化,但其关键机制尚不明确.本研究以砷污染稻田土壤中分离的一株砷甲基化功能厌氧发酵梭菌Clostridium sporogenes LHA6为对象,探究富里酸对梭菌细胞代谢活性的影响,并解析其与砷甲基化效率的内在关系.结果表明,相比对照处理,特定浓度(0.5~2 g·L^(-1))富里酸处理中菌株LHA6的水溶态和细胞结合态甲基砷生成量分别增加25.7%~84.4%和39.8%~60.4%,挥发性甲基砷产物增加0.68~1.86倍,主要产物形态为二甲基砷及其氢化物.综合电化学、代谢物和基因表达定量等方法证实:富里酸可作为胞外电子受体,抑制梭菌胞内发酵产氢活性,增加NADH/NAD+比率;同时,富里酸存在时梭菌显著上调S-腺苷甲硫氨酸(SAM)合成相关基因转录活性,增强SAM合成代谢通量,很可能是富里酸促进梭菌产生甲基砷及其氢化物的关键机制.本研究系统揭示了富里酸调控梭菌细胞代谢,进而强化其砷甲基化及挥发的砷解毒机制,获得了对砷的生物地球化学循环的新认知,有望为土壤砷污染控制提供新思路.

随着中国人口结构老龄化，公共卫生领域迫切需要应对阿尔茨海默病（Alzheimer’s disease， AD）带来的重大社会发展问题。AD临床治疗能够使用的药物十分有限且使用一段时间后治疗效果不佳。尽管全球投入大量物力和财力进行药物研发，但药物治疗临床试验进展十分缓慢。近30年来，仅有7款AD药物获得美国食品药品监督管理局（food and drug administration， FDA）批准。传统药物治疗价格昂贵且只能起到延缓AD病情作用，而无法阻止神经元退化进行性过程。因此，探究发展AD新兴治疗手段刻不容缓。光生物调节（photobiomodulation， PBM）是一种非侵入性的治疗方法，利用红光或近红外光刺激细胞代谢和细胞学反应。PBM可以改善脑部代谢和血液循环，修复脑部受损神经元，激发触突和神经元生长，有望发展成为与药物治疗互补的无创伤神经治疗手段。本文阐述了AD病理学特征、致病机理与现有治疗策略面临的难题，综述了PBM治疗AD细胞与动物模型和临床研究，总结了光疗历史与先进PBM光疗设备研发现状，最后对发展PBM治疗AD先进光子技术与光疗器械装备进行了展望。

微生物锑还原成矿有助于降低土壤锑的生物有效性和移动性,是土壤锑污染修复的重要策略之一。电子穿梭体AQDS能够加速土壤富集菌群锑还原速率,可能与其促进微生物呼吸及细胞生长有关。理解电子穿梭体(ES)介导微生物锑还原过程与机制可为土壤锑污染控制提供关键理论支撑。醌类和黄素类电子穿梭体(AQDS和FMN)存在时可能改变微生物呼吸代谢中的电子传递过程,然而ES介导下的微生物锑还原过程及转录响应机制尚不清楚。利用锑污染稻田土壤分离的兼性厌氧锑还原细菌Mesobacillus jeotgali PS1作为研究对象,探究醌类和黄素类电子穿梭体(AQDS和FMN)对菌株PS1锑还原过程及关键功能基因转录活性的影响。结果表明,菌株PS1驱动Sb(Ⅴ)还原为Sb(Ⅲ)过程中水溶态Sb(Ⅲ)随培养时间先累积后下降,培养72 h后水溶态锑去除率为64%,生成十四面体方锑矿,表明菌株PS1驱动锑还原成矿有助于锑的钝化。两种ES能够加速细菌锑还原反应,而对胞外生成的方锑矿晶型没有影响。通过定量分析菌株PS1潜在功能基因转录表达活性,结果表明AQDS相比FMN更能促进菌株PS1细胞膜二甲基亚砜还原酶(DMSOR)基因和胞内解毒型砷还原基因(arsC)转录活性,有助于增加菌株PS1呼吸代谢活性和胞内锑解毒从而加速锑还原,所以AQDS可能在强化微生物锑还原钝化中更具有优势。该研究揭示了不同电子穿梭体介导锑还原的微生物机制,为锑污染土壤生物修复提供重要理论支撑。
