肿瘤电场治疗是一种新的治疗恶性实体肿瘤的疗法,多采用电场仿真分析不同参数的肿瘤电场治疗在瘤体上产生的电场分布。但目前,由于仿真模型构建技术路线较难复现或实现成本较高,因此本研究采用常用的软件工具建立了易实现的高精度肿瘤电场治疗有限元仿真模型,模型精度在1 mm^(3)水平。本研究利用该仿真模型开展了不同组织电学参数、电极配置等因素分析,研究结果显示,对肿瘤内电场分布存在影响的因素包括:头皮、头骨电导率的变化(瘤体治疗场最高变化21.0%)、肿瘤电导率的变化(瘤体治疗场最高变化157.8%)和不同的电极位置及组合(瘤体治疗场最高变化74.2%)。综上,本文研究结果验证了所提建模方法的可行性与有效性,或可为今后的肿瘤电场治疗仿真分析和临床应用提供重要参考。

2020年区域全面经济伙伴关系协定(RCEP)的签署标志着世界上最具贸易发展潜力的自由贸易区的成立。日韩两国是我国主要的农业贸易出口国,随着贸易壁垒的进一步下降,中日韩三国农产品贸易规模是否进一步扩大值得我们深入研究。本文构建随机前沿贸易引力模型,对日韩实施的绿色贸易壁垒对中国农产品出口两国的影响进行了实证分析,研究表明:绿色贸易壁垒确实抑制了中国农产品出口日韩的贸易规模。本文就如何解决绿色贸易壁垒问题也提出了相应的政策建议。

目的观察壮医莲花针拔罐逐瘀法治疗带状疱疹后神经痛(PHN)的临床效果,以及对瞬时受体电位阳离子通道亚家族Ⅴ成员1(TRPV1)的影响。方法将96例PHN患者随机分为观察组(n=32)、对照1组(n=32)、对照2组(n=32),分别给予壮医莲花针拔罐逐瘀法治疗、中医针灸围刺治疗、加巴喷丁胶囊口服治疗。治疗后第42天评价3组的临床疗效。在治疗前、治疗后第21天、治疗后第42天,评估3组患者的疼痛视觉模拟量表(VAS)评分,检测其静脉血和穴位血的TRPV1含量及TRPV1 mRNA表达水平。结果治疗后,观察组、对照1组、对照2组总有效率分别为93.75%(30/32)、81.25%(26/32)和68.75%(22/32),观察组的总有效率高于对照2组(P<0.05)。3组患者的疼痛VAS评分随治疗时间的延长而降低(P<0.05),其中,治疗后第42天,对照2组、对照1组、观察组患者的疼痛VAS评分依次降低(P<0.05)。观察组和对照1组的静脉血和穴位血TRPV1含量及TRPV1 mRNA表达水平随着治疗时间延长而降低(P<0.05),其中,治疗后第21天、第42天,对照2组、对照1组、观察组静脉血和穴位血TRPV1含量及TRPV1 mRNA表达水平依次降低(P<0.05)。结论壮医莲花针拔罐逐瘀法治疗PHN疗效显著,镇痛效果优于中医针灸围刺及加巴喷丁胶囊口服治疗,其作用机制可能是通过下调TRPV1的表达来抑制炎症介质进一步释放,从而降低痛觉过敏,缓解疼痛。
