目的回顾性研究帕金森病(PD)患者跌倒的危险因素。方法选择香港3所医院133例的神经科专科门诊PD患者纳入研究。收集患者的人口学及临床资料,并进行躯体功能、精神、智能及跌倒方面的评估。应用logistic多元回归分析研究PD患者跌倒的危险因素。结果 44例(33.1%)患者在最近1年内有1次以上的跌倒,平均跌倒的次数为(1.9±0.7)次。logistic多元回归显示,婚姻状况(丧偶、离异或未婚)(OR=1.965,95%CI1.203～3.208,P=0.007)、Schwab和England日常生活能力评分低(OR=0.973,95%CI 0.955～0.991,P=0.003)及服用3种以上抗PD药物(OR=0.973,95%CI 0.955～0.991,P=0.026)是跌倒的独立危险因素。结论跌倒是PD患者一个很常见的问题。服用多种抗PD药物、日常生活能力及婚姻状况对跌倒均有明显的影响,提示在跌倒的预防与评估中,疾患内在因素和社会因素均需考虑。

Cyclin-dependent kinase 9(CDK9) activity is correlated with worse outcomes of triplenegative breast cancer(TNBC) patients. The heterodimer between CDK9 with cyclin T1 is essential for maintaining the active state of the kinase and targeting this protein-protein interaction(PPI) may offer promising avenues for selective CDK9 inhibition. Herein, we designed and generated a library of metal complexes bearing the 7-chloro-2-phenylquinoline CN ligand and tested their activity against the CDK9cyclin T1 PPI. Complex 1 bound to CDK9 via an enthalpically-driven binding mode, leading to disruption of the CDK9-cyclin T1 interaction in vitro and in cellulo. Importantly, complex 1 showed promising anti-metastatic activity against TNBC allografts in mice and was comparably active compared to cisplatin. To our knowledge, 1 is the first CDK9-cyclin T1 PPI inhibitor with anti-metastatic activity against TNBC. Complex 1 could serve as a new platform for the future design of more efficacious kinase inhibitors against cancer, including TNBC.

目的对一项随机研究进行分析,探讨无症状大脑中动脉狭窄患者脑白质改变(white matter changes,WMC)发生和进展的危险因素。方法对无中风症状,但存在动脉硬化危险因素的患者进行磁共振检查,入选大脑中动脉(middle cerebral artery,MCA)狭窄的患者。记录临床特点和基础血生化指标,随访2年,随访结束时再次行磁共振检查。WMC采用定量分析,体积增加超过所有患者WMC体积增加的平均值被定义为有进展。Logistic回归分析确定WMC发生和进展的独立危险因素。结果 220例无症状MCA狭窄者患中,69例存在WMC,Logistic回归分析显示年龄(OR=1.096,P<0.001)和高血压(OR=2.370,P=0.024)是WMC发生的独立危险因素。在进入研究时,69例的WMC平均体积为4.23cm3,经过两年时间增加至5.49cm3,有6例未能完成随访。随访结束时发现63例中24例(38.1%)WMC有进展。Logistic回归分析发现仅有基础WMC体积是预测WMC进展的独立危险因素(OR=1.329,P=0.003)。结论年龄和高血压是WMC发生的独立预测因素,而对于WMC的进展则是基础WMC体积更有预测意义,也就是说发现时WMC越严重,进展的机会越多,尽早发现WMC可能对于预防进展更有意义。
