Review of Policy Research, EarlyView.ABSTRACT In the face of increasingly complex environmental challenges, subnational governments play a critical role in implementing climate policies. This study investigates how intergovernmental interactions—specifically formal authority interactions and informal competitive interactions—shape the adoption of climate policies by Chinese provincial ...

血管紧张素Ⅱ1型受体抑制剂对人子宫内膜癌裸鼠皮下移植瘤的实验研究
Zhongguo shiyan zhenduanxue, 2012 目的探讨血管紧张素Ⅱ1型受体（angiotensin Ⅱ type 1receptor,AT1R）抑制剂对人子宫内膜癌移植瘤的影响。方法选择6～8周龄的雌性裸鼠,注射人子宫内膜癌HEC-1B细胞悬液,建立人子宫内膜癌移植瘤模型后,随机平均分为肿瘤组和肿瘤抑制组。观察成瘤情况,并对瘤组织进行病理组织学检查,肿瘤微血管密度（microvessel density,MVD）和VEGF阳性率测定。结果细胞株被成功接种于裸鼠体内,裸鼠皮下移植瘤和AT1R抑制剂模型成功建立。两组模型中移植瘤的大小比较有明显差异 ...

People and Nature, Volume 8, Issue 2, Page 270-282, February 2026.Abstract Chinese consumer demand for ivory threatens vulnerable African elephant populations, despite long‐standing efforts to combat the illegal wildlife trade. Behavioural science approaches have been proposed to address these systemic behaviours. However, their robust use remains uncommon in demand management interventions.

Zhongshan Daxue xuebao. Yixue kexue ban, 1989 本文探讨大脑皮层联合区对电针抑制隐神经C类纤维皮层诱发电位(C-CEP)的影响。结果表明,电针“足三里”穴对C-CEP有明显的抑制作用,并可分为早期抑制和后期抑制;电刺激大脑皮层前外侧回联合区(ALA)也可以抑制C-CEP;电针的传入信号可以到达ALA,诱发电反应;用普鲁卡因局部阻滞ALA后,电针对C-CEP的后期抑制作用减弱,提示大脑皮层联合区可能参与对C-CEP的调制过程,也可能参与电针对C-CEP的抑制作用,主要是后期抑制作用。

Flavopiridol联合Bortezomib对多发性骨髓瘤的细胞增殖抑制作用
Zhongguo shiyan zhenduanxue, 2013 目的探讨细胞蛋白激酶抑制剂Flavopiridol及蛋白酶抑制剂Bortezomib在体内抑制多发性骨髓瘤细胞U266的细胞增殖作用及其机制。方法以不同浓度的Flavopiridol及Bortezomib分别、联合作用于U266细胞,用MTT法检测细胞增殖抑制作用。采用western blot法检测Bcl-2及Mcl-1表达变化;结果①Flavopiridol比Borte-zomib对U266细胞增殖抑制作用更强,IC50值分别为52.5nM,25nM。②与单独用药相比 ...

Mechanistic Analysis of Immunomodulation by Human Induced Pluripotent Stem Cells Derived Mesenchymal Stem Cells in Mice [PDF]
, 2015 背景：间充质干细胞是具有自我更新能力和分化能力的组织细胞前体细胞，能够分化为一系列的间质细胞，包括成骨细胞、成软骨细胞、脂肪细胞、肌细胞和内皮细胞等。细胞治疗是再生医学发展的一个重要分支。越来越多的研究发现，间充质干细胞能够修复组织损伤，达到一定治疗效果。因此，间充质干细胞被视为天然组织工程材料的重要种子细胞，具有广阔的应用前景。此外，间充质干细胞具有负性免疫调节能力。在体外共培养条件下，间充质干细胞能够抑制免疫细胞功能，包括抑制T细胞反应，抑制树突状细胞的成熟和抗原提成，抑制B细胞激活和增殖 ...

SWEET1‐mediated glucose transport is crucial for energy availability in Arabidopsis
New Phytologist, Volume 249, Issue 4, Page 1816-1830, February 2026.Summary The stress‐responsive hormone abscisic acid (ABA) is known for its inhibitory effects on various physiological processes, including seed germination, often resulting in energy deprivation. Interestingly, ABA‐induced germination inhibition can be alleviated by exogenous glucose (Glc), mimicking a functional interplay between ABA and sugar ...
