体育隐性课程在高校校园文化中的作用

体育隐性课程是指受教育者通过学校体育环境以间接的、内隐的方式所获得的体育教育性经验的总和。加强体育隐性课程建设,对高校校园体育文化,促进学生素质的全面发展具有重要的作用,是构建良好的高校体育文化氛围的有效措施。

整体思维培养在牙体牙髓病科实习教学中的实践

目的　探讨整体思维培养在牙体牙髓病科实习教学中帮助学生建立临床整体思维的有效性。方法　在牙体牙髓病科临床实习中对中山大学光华口腔医学院2013级（A组,174人）和2014级（B组,92人）学生采用整体思维培养。通过出入科考核和问卷调查,并与历史同期2012级（C组,88人）学生的成绩对比等方法,评价该方法的有效性。使用SPSS 20.0进行单因素方差检验和t检验。结果　A、B组入科、出科考核成绩及病例汇报分项成绩差异无统计学意义,整体性思维分项成绩在实习后提高。与C组相比,A、B组出科考核成绩及病例汇报分项成绩均提高。问卷结果显示,87.9%（153/174）的学生认为该模式有利于整体思维建立,但77.6%（135/174）的学生认为该模式在内容和时间分配上仍需进一步改进。结论　整体思维培养模式在牙体牙髓病科实习中效果肯定,进一步完善后值得在其他科室推广应用。

Ultrasensitive determination of ascorbic acid by using cobalt oxyhydroxide nanosheets to enhance the chemiluminescence of the luminol–H2O2 system

Ascorbic acid (AA) as an essential vitamin in the human body participates in various physiological reactions and plays a key role in many biochemical processes. Therefore, it is of vital importance to monitor and quantify AA in commercial tablets, beverages and food. In this work, a rapid and ultrasensitive chemiluminescence (CL) system for the detection of AA was developed, in which ultrathin cobalt oxyhydroxide (CoOOH) nanosheets were applied in the conventional luminol–H₂O₂ CL system. The results showed that ultrathin CoOOH nanosheets as a catalyzer remarkably improved the CL intensity of the CoOOH–luminol–H₂O₂ system, up to about 1400-fold. Under the optimized conditions, the CL inhibition efficiencies increase linearly with the concentrations of AA in the range of 1–500 pmol L⁻¹, and the limit of detection was 39 fmol L⁻¹. Moreover, the proposed CL system was successfully applied in the determination of AA in medicinal tablets with satisfactory results.

An ultrasensitive CL system for the determination of ascorbic acid in medicinal tablets was developed based on the enhancement effect of cobalt oxyhydroxide nanosheets on the luminol–H₂O₂ system.     

TLR4及Hs-CRP对早产亚临床绒毛膜羊膜炎的诊断价值

目的:检测Hs-CRP及TLR4在早产亚临床绒毛膜羊膜炎孕妇外周血、脐血血清中的表达,探讨两者与早产亚临床绒毛膜羊膜炎的关系,评价其预测早产亚临床绒毛膜羊膜炎的可行性.方法:应用流式细胞术检测孕妇外周血、脐血血清中的CDl4+单核细胞上TLR4分子的表达率和平均荧光强度;用胶乳增强免疫比浊法检测外周血及分娩后脐血Hs-CRP含量.结果:早产亚临床绒毛膜羊膜炎孕妇外周血清及脐血中CDl4+单核细胞上TLR4分子的表达率和平均荧光强度及Hs-CRP水平明显高于对照组和早产非感染组,差异均有显著性.亚临床感染组孕妇外周血清及脐血TLR4的MFI与Hs-CRP成正相关.结论:TLR4联合Hs-CRP可作为早期预测感染性早产的指标.
