All-inorganic perovskite solar cells(PSCs) have potential to pass the stability international standard of IEC61215:2016 but cannot deliver high performance and stability due to the poor interface contact. In this paper, Sn-doped TiO_(2)(Ti_(1-x)Sn_(x)O_(2)) ultrathin nanoparticles are prepared for electron transport layer(ETL) by solution process. The ultrathin Ti_(1-x)Sn_(x)O_(2) nanocrystals have greatly improved interface contact due to the facile film formation, good conductivity and high work function. The all-inorganic inverted NiOx/CsPbI_(2)Br/Ti_(1-x)Sn_(x)O_(2)p-i-n device shows a power conversion efficiency(PCE) of 14.0%. We tested the heat stability, light stability and light-heat stability. After stored in 85℃ for 65 days, the inverted PSCs still retains 98% of initial efficiency. Under continuous standard one-sun illumination for 600 h,there is no efficiency decay, and under continuous illumination at 85℃ for 200 h, the device still retains 85% of initial efficiency. The 1.0 cm^(2) device of inverted structure shows a PCE of up to 11.2%. The ultrathin Ti_(1-x)Sn_(x)O_(2)is promising to improve the scalability and stability and thus increase the commercial prospect.

It is of great importance to better understand how trees regulate nitrogen(N) uptake under N deficiency conditions which severely challenge afforestation practices, yet the underlying molecular mechanisms have not been well elucidated. Here,we functionally characterized PuHox52, a Populus ussuriensis HD-ZIP transcription factor, whose overexpression greatly enhanced nutrient uptake and plant growth under N deficiency. We first conducted an RNA sequencing experiment to obtain root transcriptome using PuHox52-overexpression lines of P. ussuriensis under low N treatment. We then performed multiple genetic and phenotypic analyses to identify key target genes of PuHox52 and validated how they acted against N deficiency under PuHox52 ***52 was specifically induced in roots by N deficiency, and overexpression of PuHox52promoted N uptake, plant growth, and root development. We demonstrated that several nitrate-responsive genes(PuNRT1.1, PuNRT2.4,PuCLC-b, PuNIA2, PuNIR1, and PuNLP1),phosphate-responsive genes(PuPHL1A and PuPHL1B), and an iron transporter gene(PuIRT1) were substantiated to be direct targets of PuHox52. Among them, PuNRT1.1, PuPHL1A/B, and PuIRT1 were upregulated to relatively higher levels during PuHox52-mediated responses against N deficiency in PuHox52-overexpression lines compared to WT. Our study revealed a novel regulatory mechanism underlying root adaption to N deficiency where PuHox52 modulated a coordinated uptake of nitrate, phosphate, and iron through 'PuHox52-PuNRT1.1', 'PuHox52-PuPHL1A/PuPHL1B', and'PuHox52-PuIRT1' regulatory relationships in poplar roots.

The World Health Organization (WHO) 2017 classifications for neuroendocrine neoplasms (NENs) subdivided grade 3 pancreatic neuroendocrine neoplasms (pNENs) into G3 well-differentiated pancreatic neuroendocrine tumors (G3 pNETs) and poorly differentiated pancreatic neuroendocrine carcinomas (pNECs), according to the mitotic count, Ki-67 index, and cell differentiation. As a new category, G3 pNETs remain a challenging group of tumors to manage by lacking large randomized trials and consensus to support its clinical practice. Therefore, the Chinese Pancreatic Surgery Association, Chinese Society of Surgery, Chinese Medical Association gathered experts in this field to formulate this consensus for the diagnosis and treatment of G3 pNETs.

【目的】探究疏血通及其主要成分水蛭素对Sprague-Dawley(SD)大鼠小脑颗粒神经元(CGNs)凋亡的影响及机制。【方法】体外成熟7 d的CGNs分为存活对照组(用含K+浓度为25 mmol/L的培养基,即25 K组)、凋亡组(用含K+浓度为5 mmol/L的培养基,即5 K组)、以1/50、1/40、1/30、1/20、1/10浓度(稀释50、40、30、20、10倍)疏血通注射液处理组(25 K以及5 K合并疏血通处理组)以及对应不同浓度(2 U/mL、2.5 U/mL、3.34 U/mL、5 U/mL、10 U/mL)水蛭素处理组(25 K以及5 K合并水蛭素处理组),用Hoechst染色法观察并统计凋亡率。在蛋白印迹实验中,在25 K和5 K条件下用1/50、1/10浓度疏血通注射液以及对应2 U/mL、10 U/mL浓度水蛭素处理细胞,用Western blot法检测Cleaved Caspase-3、Bim、VEGF的表达水平。【结果】核染色结果显示,与25 K存活对照组比较,5 K凋亡组凋亡率增加;与25 K存活对照组比较,不同浓度疏血通注射液与水蛭素处理细胞后凋亡率无明显变化;与5 K凋亡组比较,不同浓度疏血通注射液与水蛭素处理细胞后凋亡率下降,且随着浓度的升高,凋亡率下降越明显。Western blot结果显示,与5 K凋亡组比较,不同浓度疏血通与水蛭素处理细胞后Cleaved Caspase-3、Bim蛋白表达水平均下降,VEGF蛋白表达水平升高。【结论】疏血通及其主要成分水蛭素通过抑制Bim表达,进而抑制线粒体依赖的小脑颗粒神经元凋亡。
