需求电压和需求电流是充电桩对电动汽车安全充电的重要依据。然而,随着电池的老化,电池管理系统的数据可能出现错误,使得电动汽车在充电时存在安全隐患。针对该问题,建立最小二乘支持向量机和深度置信网络的组合预测模型,提出一种基于变权组合模型的电动汽车充电方法。首先,针对数据掉线缺失问题,使用K均值和反距离加权方法对数据进行插值;然后,使用改进的混合核主成分分析算法对完整数据进行主成分提取,并使用改进粒子群优化算法自动确定混合核函数的权重。基于真实电动汽车数据的实验结果表明,所提方法能够准确地预测需求电压和需求电流,具有实际意义和可行性。

目的探讨康复护理在重症监护室(ICU)机械通气患者中的应用效果。方法采用前瞻性病例对照研究, 选取2020年1月至2022年4月义乌市中心医院ICU收治的意识状态良好的患者60例作为研究对象。根据护理方法将患者分为观察组和对照组, 每组30例;对照组实施ICU常规护理, 观察组在此基础上增加实施康复护理, 比较两组的康复效果。结果观察组谵妄发生率[10.00%(3/30)]低于对照组[36.67%(11/30)](χ^(2)=4.56, P=0.033);观察组已发生谵妄的病例持续时间为(1.90±0.74)d, 短于对照组的(3.11±0.85)d(t=-12.23, P<0.001);观察组患者转入普通病房时的英国医学研究理事会(MRC)肌力评分为(52.60±7.75)分, 高于对照组的(47.63±9.02)分(t=10.18, P<0.001);观察组患者ICU获得性肌无力(ICU-AW)发生率[3.33%(1/30)]低于对照组[26.67%(8/30)](χ^(2)=10.70, P<0.001);观察组患者干预后的焦虑自评量表(SAS)、抑郁自评量表(SDS)评分均低于对照组, 差异均有统计学意义(均P<0.05);观察组护理满意率[96.67%(29/30)]高于对照组[80.00%(24/30)](χ^(2)=4.04, P=0.044)。结论康复护理管理能够有效降低ICU机械通气患者谵妄及ICU-AW的发生率, 缩短患者的康复进程并改善患者心理状态, 值得借鉴。

Metastasis-associated drug resistance accounts for high mortality in ovarian cancer and remains to be a major barrier for effective treatment. In this study, SKOV3/T4, a metastatic subpopulation of ovarian cancer SKOV3 cells, was enriched to explore potential interventions against metastaticassociated drug resistance. Quantitative genomic and functional analyses were performed and found that slug was significantly increased in the SKOV3/T4 subpopulation and contributed to the high resistance of SKOV3/T4. further studies showed that slug activated c-Met in a ligand-independent manner due to elevated levels of fibronectin and provoked integrin α V function, which was confirmed by the significant correlation of slug and p-Met levels in 121 ovarian cancer patient samples. Intriguingly,c-Met inhibitor(s) exhibited greatly enhanced anti-cancer effects in slug-positive ovarian cancer models both in vitro and in vivo. Additionally, IHC analyses revealed that slug levels were highly correlated with reduced survival of ovarian cancer patients. Taken together, this study not only uncovers the critical roles of slug in drug resistance in ovarian cancer but also highlights a promising therapeutic strategy by targeting the noncanonical activation of c-Met in slug-positive ovarian cancer patients with poor prognosis.
