行云流水，画卷如歌——沟口健二电影中的东方意境美

沟口健二作为日本现代女性电影大师，作品中体现出他对东方文化、女性命运的关怀和思考。主要从沟口健二电影中的镜头语言特点——长镜头美学、女性主义以及古典文化意蕴中包含的现代性三个方面简要分析其电影中展现的东方意境美。     

不同架式对设施葡萄光合特性及果实品质的影响

以设施红提葡萄为试材,研究不同的整形方式对葡萄叶片光合特性和光合关键酶活性的影响。结果表明:与扇形整形方式相比,L形和FI形整形方式可明显提高叶面积;在果实迅速发育时期,L形整形方式显著提高了叶绿素含量,Rubisco及Rubisco活化酶活性显著升高;同时,叶片质膜ATPase和叶绿体膜ATPase活性也显著升高,从而提高了叶片的光合速率。L形、FI形和V形整形方式均不同程度提高了平均单果质量、可溶性固形物含量,降低了可滴定酸含量,而L形则显著地提高了果实的品质。因此,适当的整形方式可通过调节提高设施葡萄的叶绿含量、光合关键酶和ATPase活性来提高光合速率,最终提高果实的品质。     

红皮洋葱新品种‘西葱1号’的“一道清”高效栽培技术研究

将“一道清”的高产长效施肥技术在激光诱变选育出的红皮洋葱新品种‘西葱1号’上施用，通过与’常规施肥试验的对比，得出使用这种施肥技术可显著提高肥料利用率25％左右，能满足洋葱生长全过程的需要；还能降低洋葱早期抽薹率50％左右，改善洋葱品质，产量提高5％以上，施肥上用工减少5／4以上。在生产应用上有极好的前景。     

民办学校国民待遇问题探析

民办学校和公办学校的同等地位问题一直是严重困扰民办学校办学者和教师学生的主要问题之一。虽然《民办教育促进法》已经明确规定了民办学校与公办学校具有同等的法律地位,但是在现实中民办学校无法获得与公办学校同等的法律地位,民办学校教师、受教育者的平等地位和合法权益也得不到充分保障,造成这一现象的根本原因是立法对民办学校法人定位的缺失。

高效液相色谱-质谱法测定猪组织中硝基咪唑类药物残留量

建立了一种高灵敏度和高选择性的检测猪组织中硝基咪唑类药物残留的高效液相色谱-大气压化学电离质谱(APCI)法,可同时进行猪组织中3种硝基咪唑类药物残留的确证分析.本方法检测猪肌肉、肝脏、肾脏和皮下组织中硝基咪唑类药物的检测限为0.5～1μg/kg;空白组织添加硝基咪唑类药物水平为0.5、1、2或4μg/kg时,测得回收率:肌肉为61.1%～85.4%,肝脏为62.3%～80.4%,肾脏为61.6%～82.0%,皮下组织为63.6%～84.1%.     

Relationship between serum concentrations of IL-18, IL-10, IL-6 and acute coronary syndrome

AIM: To examine the relation between serum concentrations of interleukin-18, interleukin-10, interleukin-6 and acute coronary syndrome (ACS). METHODS: Serum concentrations of IL-18, IL-10, IL-6 were measured in 17 patients with acute myocardial infarction (AMI), 30 patients with unstable angina pectoris (UAP), 15 patients with stable angina pectoris (SAP) and 20 controls by enzyme-linked immunosorbent assay (ELISA) and radioimmunoassay (RIA).The relation between IL-18, IL-6 and IL-10 was compared. RESULTS: Serum concentrations of IL-18, IL-6 were significantly increased in the AMI and UAP groups in comparison with the SAP and control groups. Conversely, serum concentrations of IL-10 were significantly decreased in the AMI and UAP groups in comparison with the SAP and control groups. The correlation of concentrations of IL-18 and IL-6 had no significance; but the levels of IL-18 and IL-6 were negatively correlated with IL-10. CONCLUSION: Serum IL-18, IL-6 concentrations increase while serum IL-10 concentration decreases in patients with acute coronary syndromes. The inflammatory imbalance between IL-18, IL-6 and IL-10 may play an important role in the instability of atherosclerotic plaque.     

Cytocompatibiltiy of degradable calcium metaphosphate with human marrow mesenchymal stem cells

AIM: To screen the cytotoxicity of degradable calcium metaphosphate (dCMP) compared with hydroxyapatite (HA). The proliferation and differentiation abilities of human marrow mesenchymal stem cells (MSC) were used to exhibit the cytotoxicity. METHODS: The cell morphology of MSC was analysed after direct contact with dCMP at different time points by scanning electron microscopy analysis. The degradation products of dCMP and HA were analysed with inductively coupled plasma torch and ion chromatography. The cytotoxic effect of degradation products of dCMP was evaluated by FACS, quantitative assay of ALP and ARS, respectively. RESULTS: dCMP enhanced the proliferation of MSC, but didn't interfere the osteogenic differentiation process of MSC and its mineralization. HA inhibited the proliferation of MSC and the mineralization of osteogenic differentiated MSC, while it did not interfere the osteogenic differentiation process of MSC. CONCLUSION: dCMP had a better cytocompatibility with MSC than HA, which might allow for its use as skeleton scaffolds.
