目的考察大学生人性观对网络攻击行为的影响以及主观幸福感在其中的中介作用。方法采用人性的哲学修订量表、幸福感指数量表和少年网络攻击行为评定量表对247名大学生进行问卷调查。结果大学生的主观幸福感与人性观的值得信任维度呈正相关(r=0.403, P<0.01),与愤世嫉俗维度呈负相关(r=-0.189,P<0.01);主观幸福感与网络攻击行为呈负相关(r=-0.182, P<0.01);人性观的愤世嫉俗维度与网络攻击行为呈正相关(r=0.198, P<0.01)。大学生主观幸福感在人性观的愤世嫉俗维度与网络攻击行为之间起部分中介作用,中介效应占总效应的15.9%。结论愤世嫉俗的人性观可以通过主观幸福感的中介作用影响大学生的网络攻击行为。

目的评估术前白细胞与淋巴细胞比值(WLR)及p16蛋白表达检测对阴茎癌患者生存情况的预测价值。方法本研究为回顾性队列研究,选取2018年1月至2020年1月在咸阳市第一人民医院治疗的91例阴茎癌患者作为研究对象,所有患者均行阴茎部分切除术,术后对患者进行为期3年的随访,根据预后情况分为生存组(58例)和死亡组(33例)。生存组年龄(61.12±7.13)岁;死亡组年龄(60.88±7.22)岁。对比两组患者基线资料及术前影像学检查结果(肿瘤部位、肿瘤长径、神经侵犯、淋巴结转移、分化程度),测定血管内皮生长因子(VEGF)、肿瘤坏死因子受体相关蛋白1(TRAP1),并检测切除组织中p16蛋白表达情况,计算术前WLR、外周血中性粒细胞与淋巴细胞比值(NLR)、血小板与淋巴细胞比值(PLR)、单核细胞与淋巴细胞比值(MLR)。通过logistic回归分析评估患者生存情况的影响因素,并利用受试者操作特征曲线(ROC)评估WLR联合p16蛋白表达对阴茎癌患者术后死亡的预测价值。统计学方法采用t检验、χ^(2)检验。结果两组患者基线资料及肿瘤部位、肿瘤长径、分化程度比较,差异均无统计学意义(均P>0.05)。死亡组神经侵犯、淋巴结转移及p16蛋白阳性表达占比均高于生存组[63.64%(21/33)比32.76%(19/58)、57.58%(19/33)比31.03%(18/58)、66.67%(22/33)比32.76%(19/58)],差异均有统计学意义(χ^(2)=8.140、6.141、9.769,均P<0.05)。死亡组患者术前WLR、NLR、PLR、MLR及VEGF、TRAPl水平均高于生存组[(5.62±0.91)比(4.11±0.75)、(5.27±0.88)比(3.91±0.71)、(181.06±25.13)比(145.32±20.64)、(0.58±0.20)比(0.32±0.12)、(539.03±52.48)ng/L比(442.18±47.36)ng/L、(58.01±6.63)ng/L比(45.25±5.82)ng/L],差异均有统计学意义(t=8.537、8.044、7.331、7.761、9.016、9.556,均P<0.05)。logistic回归分析显示,阴茎癌患者术前肿瘤神经侵犯和淋巴结转移情况,以及p16蛋白、VEGF、TRAPl、WLR、NLR、PLR、MLR均是影响其预后的重要因素(均P<0.05)。ROC显示,WLR联合p16蛋白表达对患者死亡的预测准确度为0.943(0.896~0.990)。结论术前检测WLR及p16蛋白表达有助于评估阴茎癌患者术后生存情况。

Cold-rolled metastable β-type Ti–38Nb-0.2O alloy was subjected to annealing treatment to obtain different precipitates and grain sizes. The influence of annealing on microstructure and mechanical properties was investigated. The alloy annealed at 673 K or 773 K exhibited a single-stage yielding with high strength and low uniform elongation, due to the residual work hardening and the precipitation of ω or α phases. The alloy annealed at above873 K exhibited an obvious double yielding behavior resulting from the stress-induced martensitic transformation. The grain growth kinetics of single β phase alloy is sensitive to temperature, and it is suggested that the existence of oxygen decreases the grain growth exponent and increases the required activation energy for grain growth. The critical stress for slip decreased monotonously with the increase of grain size, following the classic Hall-Petch relationship. However, the critical stress for martensitic transformation decreased to a minimum and then increased again, as the grain size increased. The results are worth for design of the heat-treatment parameters of the Ti–38Nb-0.2O alloy for engineering applications.
