dear Editor,Industrial Internet of things(IIoT) is a typical application of cyberphysical system(CPS). In the IIoT, wireless communication is an inevitable trend to replace the deployment-limited wired transmission for cases with large-scale and mobile devices. However, wireless communication gives rise to critical issues related to physical security, such as malicious detections and attacks [1].

目的使用药物靶向孟德尔随机化的方法探索前蛋白转换酶枯草溶菌素9(PCSK9)抑制剂的应用与消化道肿瘤发生风险的因果关系。方法应用药物靶向孟德尔随机化分析,探讨PCSK9抑制剂的应用对消化道肿瘤(包括食管癌、胃癌和结直肠癌)发病率的因果关系。进行两样本孟德尔随机化研究,评估脂质[包括低密度脂蛋白胆固醇(LDL-C)、高密度脂蛋白胆固醇(HDL-C)、载脂蛋白(Apo)A-1和ApoB]与消化道肿瘤发病率之间的潜在关系,并以此判断PCSK9抑制剂抑癌作用的途径。结果通过药物靶向孟德尔随机化的方法,结果发现PCSK9抑制剂的应用与胃癌风险的下降显著相关(OR=0.36,95%CI:0.18~0.72,P=0.004),未发现PCSK9抑制剂与其他类型癌症之间存在显著的因果关系。单因素两样本孟德尔随机化分析未发现脂质成分的变化与胃癌发生率之间存在显著因果关系的关联,而多因素孟德尔随机化分析表明ApoB的水平下降与胃癌发生率的升高存在弱的因果关系关联(P=0.03,β=0.17,95%CI:0.01~0.32)。结论PCSK9抑制剂的应用有助于降低患者罹患胃癌的风险。然而,这种保护作用独立于PCSK9抑制剂的降脂作用,单纯的血脂下降无法降低胃癌的发生风险。本研究观测到的抑癌作用可能归因于PCSK9抑制剂除降脂作用外的其他机制。

In the intricate process of natural product biosynthesis, a metabolon can enhance metabolic flux by associating sequential enzymes. A fungal metabolon, comprising of flavin-dependent monooxygenase Spe F and P450 monooxygenase Spe G, is identified in the biosynthesis of spiro polycyclic alkaloids(+)-notoamide B and its diastereomer(+)-versicolamide B. Using notoamide E as a substance, Spe F/Spe G metabolon can control the stereoselectivity of its 2,3-epoxidation, followed by hydrogen atom ion at C-17 to generate reactive epoxide tau-m A with dienyl iminium unit. Subsequently,(+)-notoamide B and(+)-versicolamide B are produced via tandem nonenzymatic inverse-electron-demand Diels-Alder reaction and semipinacol rearrangement. This provides the first example of metabolon in the biosynthesis of spiro-prenylated indole alkaloids.

目的探讨脓毒性休克并发急性肾损伤(AKI)的危险因素。方法回顾性分析2016年1月至2019年12月在首都医科大学附属北京友谊医院就诊的108例脓毒症患者的临床资料,按有无AKI损伤将其均分为两组:AKI组为脓毒性休克并发急性肾损伤的患者,非AKI组为脓毒性休克未并发AKI的患者,每组各54例。比较两组患者的临床资料,包括平均动脉压(MAP)、氧合指数、血清肌酐(SCR)、乳酸、血尿素氮(BUN)、24 h液体净入量等指标。比较两组患者的白蛋白、血小板、血钾、血钠、C反应蛋白(CRP)等相关实验室指标。采用多因素logistic回归分析确定脓毒性休克并发AKI的危险因素。结果AKI组氧合指数均显著低于非AKI组,差异有统计学意义(P0.05)。将单因素分析中有统计学意义的6个影响脓毒性患者并发AKI的危险因素,包括MAP、氧合指数、血BUN、动脉血乳酸、SCR、24 h液体净入量作为协变量后进入logistic回归模型,得出SCR、24 h液体净入量、MAP及动脉血乳酸是脓毒性休克患者并发AKI的危险因素。结论SCR、24 h液体净入量、MAP及动脉血乳酸是脓毒性休克患者并发急性肾损伤的危险因素,有助于临床医生诊断早期脓毒性休克并发急性肾损伤。

新质生产力的蓬勃发展呼唤新质人才并为其培养提供了重要的时域与场域,面向新质人才需求的学校教育供给变革成为教育的基础性命题。当前面向新质人才需求的学校供给变革存在“传统型”供给主体与“新质型”主体需求、“标准化”供给内容与“个性化”内容需求、“统一性”供给方式与“数智化”方式需求之间的矛盾。鉴于此,提出面向新质人才需求的学校教育供给遵循从“人类教师主体”到“人机智能联合主体”、从“统一与他主内容”到“开放与自主内容”、从“前置性预设方式”到“发展性按需方式”的变革理路,以期为学校教育供给变革与新质人才培养提供一定的理论借鉴和实践启示。
