目的探讨星状神经节阻滞联合吗啡对晚期癌症患者癌性疼痛及抗肿瘤因子的影响。方法选取晚期癌症患者84例,按随机数字表法分为2组,各42例。对照组予以吗啡治疗,观察组在对照组基础上加用星状神经节阻滞治疗,均于治疗30 d后评价疗效。比较2组疼痛评分、吗啡使用量、自我效能感、抗肿瘤因子水平、疼痛因子水平及不良反应。结果观察组治疗15 d、30 d时VAS评分及吗啡使用量为(2.32±0.24)分、(1.89±0.24)分和(38.96±3.25)mg、(42.36±3.37)mg,低于对照组,差异有统计学意义(P0.05)。结论星状神经节阻滞联合吗啡可提高晚期癌症患者镇痛效果,减少疼痛因子分泌,减轻疼痛对患者自我效能的影响,且还可提升IFN-γ、TNF-α水平,安全可靠。

群桩基础的横向动力响应一直是岩土工程抗震领域研究的热点问题,为此开展了干砂与饱和砂土场地条件下2×2直斜群桩的离心机振动台试验,然后基于FLAC3D软件引入砂土液化大变形本构建立三维数值模型,将试验结果与数值模拟结果进行对比验证,深入分析试验和模拟中直斜群桩横向动力响应规律。结果表明:在干砂场地中,直群桩承台加速度总大于斜群桩承台加速度;在饱和砂土场地中,直斜群桩承台加速度均出现了一定程度的衰减现象,而直群桩承台的加速度衰减现象较斜群桩承台更为明显;干砂场地中桩身弯矩随桩间距的增大而减小,饱和砂土场地中桩身弯矩随着桩间距的增加呈现先增大后减小的趋势;干砂场地中承台加速度相对于输入台面加速度的放大倍数小于1时所需的桩间距大于饱和砂土场地。

Time series forecasting plays an important role in various fields, such as energy, finance, transport, and weather. Temporal convolutional networks (TCNs) based on dilated causal convolution have been widely used in time series forecasting. However, two problems weaken the performance of TCNs. One is that in dilated casual convolution, causal convolution leads to the receptive fields of outputs being concentrated in the earlier part of the input sequence, whereas the recent input information will be severely lost. The other is that the distribution shift problem in time series has not been adequately solved. To address the first problem, we propose a subsequence-based dilated convolution method (SDC). By using multiple convolutional filters to convolve elements of neighboring subsequences, the method extracts temporal features from a growing receptive field via a growing subsequence rather than a single element. Ultimately, the receptive field of each output element can cover the whole input sequence. To address the second problem, we propose a difference and compensation method (DCM). The method reduces the discrepancies between and within the input sequences by difference operations and then compensates the outputs for the information lost due to difference operations. Based on SDC and DCM, we further construct a temporal subsequence-based convolutional network with difference (TSCND) for time series forecasting. The experimental results show that TSCND can reduce prediction mean squared error by 7.3% and save runtime, compared with state-of-the-art models and vanilla TCN.
