Geological carbon dioxide (CO_(2)) utilization and storage have been widely recognized as one of the important options to deliver greenhouse gas emissions reduction. Reasonable planning is critical to promote CO_(2) utilization and storage. However, CO_(2) emissions gas collection exhibits a stochastic probability distribution, and CO_(2) utilization and storage features fluctuation demands, which have gone beyond current determine planning techniques. To fulfill the current research gap, this study develops an interval-parameter two-stage programming-based CO_(2) collection, distribution, transportation, utilization, and storage optimization model, integrating interval parameter planning and two-stage planning into a general framework. Therefore, the model can address uncertainties expressed as random probabilistic distributions and discrete intervals, tackle dynamic facilities capacity expansion issues, develop optimal predefined CO_(2) distribution policy, and generate recourse schemes to address gas shortage or gas surplus issues. The model is examined by a typical hypnotical case study in China. The results revealed that the model could generate a set of first-stage reasonable CO_(2) distribution and facilities capacity expansion schemes to maximum system beneﬁts and the highest feasibility. Besides, a set of two-stage CO_(2) outsourcing purchases and facilities capacity expansion in reserve storage regions solutions were also generated to address the gas oversupplies and shortage issues. The modeling approach enriches the current CO_(2) utilization and storage distribution research content under multiple uncertainties.

Objective To explore the effectiveness of renal denervation (RDN) on blood pressure with the appropriate dosage of phenol/ethanol solution in spontaneously hypertensive rats (SHRs). Methods RDN was performed on the bilateral renal artery. Forty SHRs were divided into four groups according on the dosage of phenol (10% phenol in absolute ethanol): sham group, 0.5 mL phenol group, 1 mL phenol group and 1.5 mL phenol group (n = 10 in each group). Blood pressure was measured by tail-cuff plethysmography. Plasma creatinine was determined four weeks after the treatment. The kidneys and renal arteries were collected and processed for histological examination. Results A sustained decrease in systolic blood pressure (SBP) was only observed after the application of 1 mL phenol for four weeks, while SBP was lowered during the first week after RDN and increased in the following three weeks in the 0.5 mL and 1.5 mL phenol groups compared with the sham group. Renal norepinephrine (NE) was significantly decreased four weeks after RDN in the 1 mL and 1.5 mL phenol group compared with the sham group, but not in the 0.5 ml group. RDN with 1 mL phenol obviously reduced glomerular fibrosis. Histopathological analysis showed that tyrosine hydroxylase immunoreactivity was lower in the 1 mL and 1.5 mL phenol groups compared with the sham group. Moderate renal artery damage occurred in the 1.5 mL phenol group. Conclusion Chemical denervation with 1 ml phenol (10% phenol in absolute ethanol) effectively and safely damaged peripheral renal sympathetic nerves and contributed to the sustained reduction of blood pressure in SHRs.

采用1.0×10^(7)~2.0×10^(8)cfu/mL的鳗鲡爱德华氏菌感染美洲鳗鲡以确定其半数致死量(LD_(50)),然后采用略低于LD_(50)的菌浓度(3.3×10^(6)cfu/尾)感染鳗鲡,并于感染后12、24、36、48、60、72 h等6个时间点检测鳗鲡肝脏、肾脏和血液的载菌量,同时观察感染后36、60 h鳗鲡肝脏、肾脏和脾脏的病理变化。此外,采用qRT-PCR方法探究感染前和感染后12、36、60 h等4个时间点细菌外膜蛋白A(OmpA)和宿主抗鳗鲡爱德华氏菌感染的16个免疫相关基因表达。结果表明:感染鳗鲡爱德华氏菌后,美洲鳗鲡的LD_(50)为2.5×10^(5)cfu/g(5.0×10^(6)cfu/尾);美洲鳗鲡肾脏的载菌量于感染后36、48、60 h均显著高于在肝脏和血液中的载菌量,且感染后36 h菌浓度在肾脏和血液中均达到峰值,而在肝脏中的峰值则为感染后72 h。感染后36 h鳗鲡肝脏血管充血,肾小球萎缩且肾小管上皮细胞脱落,脾脏血管内形成血栓;感染后60 h肝血管出现血栓且部分肝细胞坏死,肾小管上皮细胞空泡变性并脱落入肾小管管腔,脾脏出现大量因细菌感染而导致的坏死性结节。与感染前相比,感染后12 h细菌OmpA基因在肝脏的表达量显著(P<0.05)升高;感染后OmpA基因在脾脏的表达量先下降后急剧上升,在肾脏的表达量则先上升后下降再上升。鳗鲡抗爱德华氏菌感染的5个免疫球蛋白相关的基因,在肝脏和肾脏不同时间点的表达量均无明显差异,而感染后早期在脾脏的表达量显著高于晚期;感染后3个肿瘤坏死因子相关基因在早期的表达量相对较高;此外,感染后12 h多个免疫相关基因表达量显著上升。

A series of new antitumor compounds having indolecarbazole structures were designed and synthesized. The methoxy substituted indolecarbazole parent nucleus, which was firstly synthesized, is condensed with bromine substituted amino acid methyl ester to produce the target compounds. The target compounds were performed with methylthiazolyldiphenyl-tetrazolium bromide（MTT） in vitro cytotoxin activity test and the results showed that compounds CZ-1, CZ-3 and CZ-6 have higher activity against human colon cancer（HT-29） and（HCT-8）, hepatocellular carcinoma（Bel-7402）, NSCLC（A549） and breast cancer（MCF-7） cells as compared to the positive control JDC-108.
