论外来词

随着科学技术的迅猛发展以及我国对外交往的日益频繁,外来词（借词）特别是英语词汇越来越多地渗透到我们的日常生活中.不少人对此表现出了很深的忧虑：这会不会破坏汉语文字的纯洁性？本文主要对外来词所涉及的内容、存在的依据、借用的形式以及应用等方面进行探讨,并着重指出外来词不会影响汉语的纯洁性;相反,外来词的借入会不断地丰富我们的语言宝库,因此人们应该以一种更开放的心态来吸纳外来词.     

Studies on Tomato Seedling Quality Indices Under Simulated Shipping and Storage Conditions

Indices of the tomato seedling quality maintenance level after production before field planting were studied through simulated experiments, small--scale operation, indoor analyses and measurements, and field observation. The results showed that under simulated shipping and storage conditions, seedling quality change following different durations (days) of shipping and storage was correlated significantly or even very significantly with certain physiological and morphological indices. With various measured indices following different periods of shipping and storage treatment subjected to multinomial successive regressive correlation analysis, the principal factors influencing seedling quality maintenance level are identified to be chlorophyll content→dry short weight→ leaf freshness index in order of their importance. Significance analysis with multinomial fitted equation indicated that correlations between any one of above three factors and the growth index after field planting reached very significant difference level.     

城镇化水平计算方法比较分析

城镇化是社会经济发展的必然趋势，与小城镇人口、经济实力、社会发展和环境保护等方面密切相关。城镇化判别指标归纳起来分两大类：一类是单一指标法或称主要指标法；另一类是多项指标法、复合指标法或称综合指标法。在常用的、单一指标法的城镇化水平计算方法中，城镇人口比重指标法和带眷系数法两种方法能够比较准确地反映小城镇的城镇化水平，尤其以城镇人口比重指标法计算结果最符合实际。

Effect of bFGF on glucose regulated protein 78 expression and apoptosis in human ovarian cancer CAOV3 cells

AIM: To evaluate the effect of bFGF on the apoptosis and the expression of glucose regulated protein 78 (GRP78) in ovarian cancer CAOV3 cells.METHODS: Starvation induced cell apoptosis was conducted. After treatment with bFGF, the cell cycle and apoptosis were determined by FACS analysis and Annexin V/PI staining, respectively. The expression of protein kinase B (PKB) and GRP78 were detected by Western blotting and RT-PCR. RESULTS: Compared to starvation group, the cells treated with bFGF were still viable and increased activation of PKB and high expression of GRP78 were observed, which were prevented by PKB inhibitor wortmannin effectively (P<0.01). CONCLUSION: bFGF plays a critical role in anti-apoptosis and proliferation in human ovarian cancer through PKB signal transduction pathway, partly by upregulating the expression of GRP78.     

不同稀释液对藏獒精液保存效果的影响

比较了8种稀释液在藏獒精液冷冻保存和低、常温保存(5 ℃,10 ℃,15 ℃,20 ℃)的效果.结果表明:2号和8号稀释液在冷冻保存时效果最好,精子活力和顶体完整率分别达到0.40和49%,与对照组相比差异显著(P<0.05).在藏獒的低温、常温保存试验中,所有稀释液在15 ℃时保存时间最长,综合考虑,7号液保存效果最好;在15℃时精子平均存活时间为103 h,显著高于对照组和其它稀释液(P<0.05).
