关于国民经济和社会信息化的思考

信息化是当今世界经济和社会发展的大趋势，它引起社会经济生活一系列根本性变化。大力推进国民经济和社会信息化，以信息化带动工业化，是加速我国现代化进程的战略举措和应对日益激烈的国际竞争的迫切要求。推进我国国民经济信息化应遵循以下基本原则抓住机遇，发挥后发优势，努力实现信息产业的跨越式发展；重视运用信息技术改造和提高传统产业；以人为本，着眼于人民生活消费水平的提高和全面发展。     

角色扮演法在国际贸易课程中的应用研究

＂行为导向＂一词最早出现于20世纪80年代,它是世界职业教育教学理论发展过程中的一种新思潮。角色扮演法是行为导向教学法中最具代表性的教学方法之一,它强调通过模拟实景,让学生身临其境地参与到教学过程中,通过自己的实践或行动来培养和提高职业能力。国际贸易作为中职学校商贸类专业的必修课程之一,通过引入角色扮演法使学生充分发挥其形象思维的优势,将复杂的国际贸易过程、国际贸易关系变得更加直观,从很大程度上降低了课程的难度,提高了学生的学习效率。

制造链中合作研发的契约设计研究

在考虑制造链中一个制造商和多个供应商的努力水平下,构建其合作研发的一般契约和利益共享契约模型。结果表明,在一般契约中转移支付价格与供应商努力水平和制造商成本系数呈正相关,与制造商努力水平、供应商成本系数和供应商数量呈负相关;在利益共享契约中转移支付价格与制造商分配比例和供应商努力水平呈正相关,而与制造商努力水平呈负相关。最后得出在合理的利益分配区间内共享契约是较优选择的结论。     

Synthetic biology in the view of European public funding organisations

We analysed the decisions of major European public funding organisations to fund or not to fund synthetic biology (SB) and related ethical, legal and social implication (ELSI) studies. We investigated the reaction of public organisations in six countries (Austria, France, Germany, the Netherlands, Switzerland and the U.K.) towards SB that may influence SB's further development in Europe. We examined R&D and ELSI communities and their particular funding situation. Our results show that the funding situation for SB varies considerably among the analysed countries, with the U.K. as the only country with an established funding scheme for R&D and ELSI that successfully integrates these research communities. Elsewhere, we determined a general lack of funding (France), difficulties in funding ELSI work (Switzerland), lack of an R&D community (Austria), too small ELSI communities (France, Switzerland, Netherlands), or difficulties in linking existing communities with available funding sources (Germany), partly due to an unclear SB definition.     

中国薯蓣属根状茎组系统分类的初步研究

   本文根据我国薯蓣属(Dioscorea L．)根状茎组(Sect.  Stenophora Uline)的外部形态特征、细胞染色体数、花粉形态、植物化学成分、地理分布等的规律，证明根状茎组是该属中的一个比较原始的自然类群：1．具横走的多年生地下根状茎，其它组是一年生或多年生的块茎；2．大部分是2倍体，其它组是多倍体；3．花粉粒单沟型，外壁纹饰网纹或颗粒条纹，其它组为双沟型，外壁纹饰网纹；4．含甾体皂甙元(steroidal sapogenin)，其它组不含。   我们的研究观察证明，N．N．TepaCNMeHKO根据R.Knuth系统(1924)提出的薯蓣皂甙元在该属中无分布规律的说法是无充分依据的。   本文讨论了某些组或种的划分及系统位置：取消sect.Illigerestrum Prain et Burk.；将马    肠薯蓣(D．simulans Prain et Burk．)改属根状茎组；触丝薯蓣(D．tentaculigera Prain et Burk.)应列入顶生翅组  (Sect．shannicorea Prain et Burk．)，  并提出了盾叶薯蓣  (D. zingiberensis  Wright)和穿龙薯蓣(D．nipponica Makino)种的划分和定名的意见。

Ecological principle meets cancer treatment: treating children with acute myeloid leukemia with low-dose chemotherapy

Standard chemotherapy regimens for remission induction of pediatric acute myeloid leukemia (AML) are associated with significant morbidity and mortality. We performed a cohort study to determine the impact of reducing the intensity of remission induction chemotherapy on the outcomes of selected children with AML treated with a low-dose induction regimen plus granulocyte colony stimulating factor (G-CSF) (low-dose chemotherapy (LDC)/G-CSF). Complete response (CR) after two induction courses was attained in 87.0% (40/46) of patients receiving LDC/G-CSF. Post-remission therapy was offered to all patients, and included standard consolidation and/or stem cell transplantation. During the study period, an additional 94 consecutive children with AML treated with standard chemotherapy (SDC) for induction (80/94 (85.1%) of the patients attained CR after induction II, P = 0.953) and post-remission. In this non-randomized study, there were no significant differences in 4-year event-free (67.4 vs. 70.7%; P = 0.99) and overall (70.3 vs. 74.6%, P = 0.69) survival in the LDC/G-CSF and SDC cohorts, respectively. After the first course of induction, recovery of white blood cell (WBC) and platelet counts were significantly faster in patients receiving LDC/G-CSF than in those receiving SDC (11.5 vs. 18.5 d for WBCs (P < 0.001); 15.5 vs. 22.0 d for platelets (P < 0.001)). To examine the quality of molecular response, targeted deep sequencing was performed. Of 137 mutations detected at diagnosis in 20 children who attained hematological CR after two courses of LDC/G-CSF (n = 9) or SDC (n = 11), all of the mutations were below the reference value (variant allelic frequency <2.5%) after two courses, irrespective of the treatment group. In conclusion, children with AML receiving LDC/G-CSF appear to have similar outcomes and mutation clearance levels, but significantly lower toxicity than those receiving SDC. Thus, LDC/G-CSF should be further evaluated as an effective alternative to remission induction in pediatric AML.
