Asian Agricultural Research 2017年第3期9卷 93-95,105页

作者： Xiaoxia LIU Zhe ZHANG guangfeng WANG Lingli lu Junjun WANG Yiding CHEN Zhejiang Agricultural Technology Extension Center Soil and Fertilizer Station of Lanxi Municipal Bureau of Agriculture Zhejiang Zhenong Agricultural Science and Technology Co. Ltd. Zhejiang AMP International Co. Ltd.

By the field experiment,we set up the treatments of non-application of potash fertilizer,conventional fertilization,balanced fertilization and halved application of potash fertilizer,and studied the effect of different treatments on rice yield and soil nutrient content. The results showed that compared with non-application of potash fertilizer,conventional fertilization and balanced fertilization significantly increased the spike length,thousand kernel weight,yield and total potassium content of the stalk,as well as soil organic matter,total nitrogen and available phosphorus content; compared with conventional fertilization,the balanced fertilization did not significantly increase the rice growth and yield,but effectively increased rice grain total nitrogen,stalk total nitrogen and total phosphorus content,as well as soil available phosphorus and available potassium content. It could be found that potash fertilizer played a certain role in increasing rice yield and soil nutrient content,and the balanced fertilization had the most significant effect.

Asherman's syndrome(AS) is a common disease that presents endometrial regeneration disorder. However, little is known about its molecular features of this aregenerative endometrium in AS and how to reconstruct the functioning endometrium for the patients with AS. Here, we report that ΔNp63 is significantly upregulated in residual epithelial cells of the impaired endometrium in AS; the upregulated-ΔNp63 induces endometrial quiescence and alteration of stemness. Importantly, we demonstrate that engrafting high density of autologous bone marrow mononuclear cells(BMNCs) loaded in collagen scaffold onto the uterine lining of patients with AS downregulates ΔNp63 expression, reverses ΔNp63-induced pathological changes, normalizes the stemness alterations and restores endometrial regeneration. Finally, five patients achieved successful pregnancies and live births. Therefore, we conclude that ΔNp63 is a crucial therapeutic target for AS. This novel treatment significantly improves the outcome for the patients with severe AS.

飞机发动机进气道前缘唇口积冰将会严重威胁航空安全,仿生研究表明具有微纳结构的疏水表面可以起到良好的抑冰效果。针对飞机唇口材料TC4,采用飞秒脉冲激光诱导制备TC4微结构表面,利用三维形貌仪和扫描电镜对TC4合金表面三维形貌和微纳结构进行观测,应用接触角测量仪分析表面浸润改性,依托结冰特性实验系统测试微结构表面抑冰抑霜性能,并分析飞秒脉冲激光加工工艺参数对表面微观结构和抑霜特性的影响机制。研究结果表明:随着激光扫描速度的增大,TC4合金表面形成的拱形沟壑深度增加,沟壑上方出现干涉条纹以及圆形凸起且微纳凸起的尺寸随扫描速度的增大而增大,接触角先减小后增大再减小;加工后表面液滴冻结时间比未加工表面延迟30s;扫描速度2000mm/s时的液滴冻结时间最长,霜层质量最小,高度最低。飞秒激光加工TC4合金表面形成的微纳结构以及表面吸附的有机物能够改变表面接触角;粗糙度和表面形貌能够影响表面结冰时间和结霜量。

铝作为目前最经济且应用最为广泛的材料之一,具有重量轻、耐腐蚀、导热性好、导电性好等优点。然而,金属铝在氯离子环境中容易发生点蚀。根据中性溶液中铝表面点蚀反应机理,结合液体流动和相变特性,建立了三维格子Boltzmann铝点蚀模型,研究了中性溶液中铝表面的点蚀现象,弥补了传统实验方法的不足。采用建立的腐蚀模型对整个铝点蚀过程进行了模拟,得到了不同组分的浓度分布以及不同参数与腐蚀程度的关系。结果表明:铝的腐蚀程度随接触时间的增加而增加。随着初始氯离子浓度的增加和腐蚀反应速率的增大,铝被腐蚀得更严重。三维格子Boltzmann铝点蚀模型为金属腐蚀数值研究提供了新的思路。
