目的探究血小板计数(PLT)、癌胚抗原(CEA)和蛋白基因产物9.5(PGP9.5)水平对晚期非小细胞肺癌(NSCLC)患者疗效和预后的预测价值。方法本研究为回顾性队列研究。采用非随机抽样的方法纳入2016年1月至2022年12月在空军军医大学唐都医院确诊并接受紫杉类+顺铂化疗方案治疗的62例晚期NSCLC患者。采用电话和门诊随访的方式对患者的预后情况进行追踪调查,随访时间至少半年,随访截止日期为2023年6月。评估所有患者化疗后6个月的疗效,根据实体瘤疗效评价标准将所有患者分为进展组(疾病进展,37例)和缓解组(完全缓解+部分缓解+疾病稳定,25例)。收集患者的一般资料(性别、年龄、吸烟史、手术史、临床分期和病理类型),化疗前1周PLT、肿瘤标志物[鳞状细胞癌相关抗原(SCC)、铁蛋白(FRT)、细胞角蛋白19片段(CYFRA21-1)、CEA、肿瘤标志物糖类抗原50(CA50)、神经元特异性烯醇化酶(NSE)、糖类抗原125(CA125)]水平和肺癌自身抗体(抑癌基因53(P53)、PGP9.5、肿瘤/睾丸抗原G抗原7(GAGE7)、三磷酸腺苷结合RNA解旋酶自身抗体4-5(GBU4-5)、性别决定基因家族2(SOX2)、黑色素瘤抗原A1(MAGEA1)、肿瘤相关基因(CAGE))水平。比较2组患者一般资料,化疗前PLT、肿瘤标志物和肺癌自身抗体的水平。采用受试者操作特征(ROC)曲线分析化疗前PLT、肿瘤标志物和肺癌自身抗体对晚期NSCLC患者疗效的预测效能。采用多因素logistic回归分析确定影响晚期NSCLC患者疗效的独立危险因素。采用Kaplan-Meier法绘制生存曲线,Log-rank检验比较不同表达水平的各独立危险因素患者的生存状态。结果缓解组中男17例,女8例,年龄62.0(53.0,69.0)岁;进展组中男27例,女10例,年龄63.0(56.0,69.0)岁。2组患者的临床分期比较差异有统计学意义(χ^(2)=1.98,P=0.048);性别、年龄、吸烟史、手术史和病理类型比较,差异均无统计学意义(均P>0.05)。进展组患者化疗前PLT、CEA、CA125、PGP9.5、GBU4-5和CAGE的表达水平均高于缓解组,差异均有统计学意义(均P0.05)。ROC曲线分析显示,PLT、CEA、CA125、PGP9.5、GBU4-5和CAGE预测NSCLC患者疗效的曲线下面积分别为0.756(95%CI:0.614~0.874)、0.854(95%CI:0.746~0.947)、0.760(95%CI:0.633~0.887)、0.788(95%CI:0.664~0.912)、0.739(95%CI:0.604~0.875)和0.741(95%CI:0.608~0.875),最佳截断值分别为221.00×10^(9)/L、5.00 U/L、35.00 U/L、3.08 U/ml、9.91 U/ml和0.37 U/ml,预测效能良好。多因素logistic回归分析显示,PLT>221.00×10^(9)/L、CEA>5.00 U/L和PGP9.5>3.08 U/ml是影响晚期NSCLC患者疗效的独立危险因素(OR值分别为1.015、1.191、1.906,均P221.00×10^(9)/L)患者的中位生存时间为22.00个月(95%CI:18.65~25.35),PLT低表达(≤221.00×10^(9)/L)的中位生存时间为27.00个月(95%CI:19.28~34.73),化疗前PLT低表达患者的生存状态优于PLT高表达患者(χ^(2)=9.00,P=0.003)。CEA高表达(>5.00 U/L)患者的中位生存时间为18.80个月(95%CI:13.12~22.89),CEA低表达(≤5.00 U/L)的中位生存时间为27.30个月(95%CI:24.31~29.69),化疗前CEA低表达患者的生存状态优于CEA高表达患者(χ^(2)=7.29,P=0.016)。PGP9.5高表达(>3.08 U/ml)患者的中位生存时间为7.76个月(95%CI:4.76~9.24),PGP9.5低表达(≤3.08 U/ml)的中位生存时间为25.31个月(95%CI:22.81~27.16),化疗前PGP9.5低表达患者的生存状态优于PGP9.5高表达患者(χ^(2)=21.66,P<0.001)。结论PLT、CEA和PGP9.5的表达水平可用于晚

对撞球机器人的母球控制问题展开研究,设计了一种基于神经网络(NN)的控制器,使机器人能够控制母球在击打目标球后按照预定的模式运动至目标点——即完成走位。针对该问题非线性且非光滑的特点,对坐标系进行阐述并给出机器人击球的模型;在光滑的假设下使用理论分析的方法建立母球的运动学模型与边库反弹的理想镜像模型;进而使用神经网络方法对理想模型进行修正,并对不同的轨迹模式进行分析与分类。测试结果表明:经过训练的机器人能够掌握各种模式的走位,统计结果与模型分析结果相吻合;相比于单一使用神经网络方法,本文使用理论分析与神经网络相结合的方法能够有效地提升网络的品质,降低训练的误差。

作为"五四"新文化运动的主将,鲁迅力主"以白话取代文言",自己却始终不放弃旧体诗创作,这是意味深长的事实存在。这既是一种个人趣味的体现,又是一种语言意识的彰显。鲁迅旧体诗的美学特征主要体现在以理性节制情感、士传统下的文人趣味以及诗意模糊形成的多义阐释空间三个方面,这些旧体诗记录了自己过往的生活和相对私密的情感经历,并从语言层面、内容层面、思想层面全方位、多角度拓宽了旧体诗的表达疆界,具有独特的美学价值,有助于我们深化对鲁迅文学创作与美学思想的理解。
