科技创新对科技人才聚集的影响及其空间溢出效应——基于空间面板Durbin模型的实证研究

基于2000-2017年省际面板数据和空间面板Durbin模型,研究了地区科技创新能力对科技人才聚集的影响及其空间溢出效应。结果表明：地区科技创新能力提升不仅有助于本地区科技人才的聚集,也有利于通过溢出效应促进邻近地区的科技人才聚集;科技创新能力提升对科技人才聚集的影响具有显著的地区差异;科技创新与科技人才聚集均具有空间相关性。因此,应强化科技创新与科技人才聚集的结合,在完善多方联动机制的基础上共建跨区科技人才流动平台,科学构建科技人才自由流动机制,并引导科技人才向科技创新优势和创新特色地区聚集。     

CT-VRT测量西南地区汉族人胸骨柄体和与身高的相关性

目的采用CT容积再现技术(CT volume rendering technique,CT-VRT)测量西南地区汉族人胸骨柄体和,建立其与身高的回归方程。方法 160例(男、女性各80例)西南地区汉族成年体检者通过CTVRT(重建层厚1 mm)分别测量胸骨柄长和体长,二者的代数和即为柄体和。同时测量受检者真实身高,分别建立男、女性柄体和与身高的回归方程。结果分别建立了男、女性胸骨柄体和(x3)与身高(y)之间关系的一元回归方程(男性:y=135.000+2.118 x3;女性:y=120.790+2.808 x3)。两方程均具有统计学意义(P0.05),且预测准确性均为100%。结论 CT-VRT能作为胸骨指标测量的有效方法。采用CT-VRT测量的胸骨柄体和能应用于西南地区汉族人身高推算。     

Distinguishing the viewers,downloaders, and exchangers of Internet child pornography by individual differences: Preliminary findings

The current study assessed the relationship between personality and cognitive differences and the respondents' level of engagement in child pornography (searching for/viewing, downloading, or exchanging). 273 respondents completed the anonymous online survey; 257 respondents (94%) were classified as non-child pornography consumers, and 16 respondents (6%) were classified as Internet child pornography consumers. When only considering the child pornography users, 63% (n = 10) were categorized as searchers/viewers, 18.5% (n = 3) were categorized as downloaders, and 18.5% (n = 3) were categorized as exchangers. When discriminating between child pornography consumers, those individuals who only searched for and viewed child pornography were less extraverted than those individuals who reported exchanging Internet child pornography. Higher scores on extraversion may reflect the offender's ability to socially network on the Internet in order to gain access to child pornography (i.e., exchanging/sharing). Significant correlations also suggested a relationship between child pornography behaviors, conscientiousness, and excitement-seeking. Future research suggestions and limitations are discussed.     

化瘀温经利湿法治疗慢性盆腔炎20例临床观察

目的观察化瘀温经利湿中药对慢性盆腔炎患者的疗效及对外周血CD4^＋CD25^＋CD127^lo调节性T细胞（regulative Tcells，Treg）的影响。方法将40例慢性盆腔炎患者按随机数字表法分为化瘀温经利湿中药治疗组20例和西药对照组20例，两组均以1个月为1个疗程，均治疗1个疗程，观察临床疗效及对症状出现率的影响；采用流式细胞术检测患者治疗前后外周血CD4^＋CD25^＋CD127^loTreg的数量及其在CD4^＋T淋巴细胞中所占的比例；并检测治疗前后血沉（erythrocyte sedimentation rate，ESR）和C反应蛋白（C—reactive peptide，CRP）水平。结果与对照组比较，治疗组总有效率和CD4^＋CD25^＋CD127^loTreg表达水平显著升高，ESR、CRP及症状出现率显著降低（P〈0．05）。结论化瘀温经利湿中药治疗慢性盆腔炎的作用机制，可能与其上调CD4^＋CD25^＋CD127^loTreg表达水平，促进免疫调节，降低炎症反应有关。
