The Juhugeng Sag,located in northwest of the Muli Basin,Tibetan Plateau,has been investigated for coal and petroleum resources during the past several *** have been successful recoveries of gas hydrates during recent years from the Middle Jurassic Yaojie Formation that offer insight into the origin of the hydrocarbon gases from the complex sag *** study examines the organic geochemical and stable carbon isotopic characteristics of shale and coal samples from the Middle Jurassic Yaojie Formation of the Juhugeng Sag,as well as compares with carbon isotopes,gas amounts and components of hydrate-bound gas.A total of 19 samples from surface mining,including 12 samples of black shale and 7 samples of coal,were analysed using a micro-photometer,a gas chromatograph,Rock–Eval and isotope *** the shale samples contained 100%type I kerogen,and the random vitrinite reflectance values vary from 0.65%to 1.32%and achieve thermal pyrolysis *** values of methane(δ13C ranging from−52.6‰to−39.5‰andδD ranging from−285‰to−227‰)in the hydrate bound gases suggest that the methane originates mainly from thermogenic *** is proposed that ethane from the gas hydrate is thermogenic-produced,and this conjecture is supported by the fact that most of the gas hydrate also contains more than 30%of thermogenic C2+hydrocarbons and is similar to structure II *** isotope data from the gas hydrates show a positive carbon isotope series(δ13C1<δ13C2<δ13C3),with ethaneδ13C values being lighter than−28.5‰,as high consistency with source rocks from the Jurassic period indicate thermal oil-prone gas.A model of the accumulation of gas hydrate is ***,the gaseous sources of gas hydrates may be a subject for more research.

从医务人员、承运人及社会公众三重视角出发对“高铁急救”事件中所蕴含的法律问题进行解析可知:医务人员在院外实施紧急医疗救助时,既不会被认定为非法行医而面临行政法律风险,也不会因过失承担任何不利的民事赔偿风险。承运人对乘客患者具有救治义务,但无需达到医疗专业人员的救治水平。此外,承运人注意义务内容不应包括查验救助者职业身份。于公共场所配备急救设备并通过培训使现场第一目击者掌握急救技能,应当成为当前社会提升自救互救能力的最佳选择。

Effect of dopamine and metaraminol on the renal function of patients with septic shock

引用

Chinese Medical Journal 2007年第8期120卷 680-683页

作者： HOU Li-chao LI Shu-zhi XIONG Li-ze CHEN Shao-yang CHEN Min ZHANG Xi-jing huo ting-ting WANG Qiang WANG Ya-li HU Wen-neng Department of Anaesthesiology Xijing Hospital Fourth Military Medical University Xi＇an 710032 China

Background Vasoactive drugs are often necessary for reversing hypotension in patients with severe infection. The standard for evaluating effects of vasoactive drugs should not only be based on the increase of arterial blood pressure, but also on the blood flow perfusion of internal organs. The effects of dopamine and metaraminol on the renal function of the patients with septic shock were investigated retrospectively in this study. Methods Ninety-eight patients with septic shock were divided into three groups according to the highest infusing rate of metaraminol, with the lightest infusing rate of （0.1-0.5, 0.6-1.0, 〉1.0） pg · kg^-1 · min^-1 in group A, B and C respectively. Urine output, mean arterial blood pressure （MAP）, heart rate （HR）, urine output, blood urea nitrogen （BUN）, creatinine （CRE）, urine albumin （U-ALB）, urine β2-microglubulin （Uβ2-MG） and Apache Ⅲ scores were recorded. Results Before antishock therapy, hypotension, tachycardia and oliguria occurred to all the 98 patients with septic shock and CRE, BUN, U-ALB, Uβ2-MG and Apache Ⅲ scoring were abnormal in most cases. With the antishock therapy, MAP, HR, urine output, BUN and CRE in all patients returned gradually to normal （P〈0.05 or 〈0.01 compared to those before antishock therapy）. U-ALB, Uβ2-MG output and Apache Ⅲ scoring also reverted but remained abnormal （P〈0.01 compared to those before antishock therapy）. No statistically significant differences in the changes of these indices with the time existed among the three groups （P〉0.05）.Conclusion Dopamine and metaraminol when applied to the patients with septic shock could effectively maintain the circulatory stability and promote restoration of renal function.

低碳经济是发达国家为应对气候变化而提出的新的经济发展模式,它正成为一种新的国际潮流,影响着各国的经济社会发展进程。本文从低碳经济与经济增长、低碳经济实现的制度安排和不同国家的低碳经济进程三个方面,对国外相关文献进行梳理,分析认为:影响一国碳排放量的因素有人口、GDP、能源强度、碳强度及国际贸易等,且从长期来看,碳减排不会对经济增长造成负面影响;征收碳税和碳交易制度是目前实现低碳经济的主要制度安排;无论是发达国家还是发展中国家都在努力行动,实现经济发展模式向低碳经济转型。

By detecting the influence of six main ingredients of PM2.5 mineral dusts on the A549 cell morphology, proliferation inhibition rate, micronuclei and DNA damage, to explore the genotoxicity of PM2.5 mineral dusts. (1) After exposure to six kinds of dusts of 200 μg/mL concentration for 24 hours, the morphology of A549 cells were observed using Wright-Giemsa staining. (2) After exposure to different concentrations of mineral dusts for 24 hours, the proliferation inhibition rate of A549 cells was detected by MTT assay. (3) Cells were exposed to PM2.5 mineral dusts at a concentration of 200 μg/mL for 24 h. After Wright-Giemsa staining, the rates of micronucleus cells were counted under oil microscope. (4) Observe Comet phenomenon by SCGE electrophoresis, the degree of DNA damage was observed by OTM. (1) Compared to the control group, membrane destruction, nuclear pyknosis and mineral surface adhesion were mainly seen in the Sericite group and Albite group. In the Quartz group and Montmorillonite group, enlarged cell gaps, loosely arranged cells, absorption of a large number of minerals on the cell surface, and cell pyknosis were observed. (2) The proliferation inhibition rate of the six kinds of dusts to A549 cells were (from large to small): KWC-M>Nano-SiO2>KWC-S>KWC-Q>KWC-A>*** dust concentration was positively related to the inhibition of cell proliferation rate. (3) With the dusts concentration increased, the incidence of micronuclei gradually increased. The rate was positively correlated to exposure concentration. (4) The six mineral dusts can damage DNA of the A549 cells by dose-response *** higher concentration of the mineral dusts, the more obvious of the DNA damagenation. There’s statistically significant compared with the control group. The six main ingredients of the PM2.5 mineral dusts can change A549 cell morphology from varying degrees, improve proliferation inhibition rate of the cells, increase the number of micronuclei cells, damage D

矿物学报 2013年第S1期33卷 134-134页

Detect the change of the Expression of oncoprotein on the Chinese hamster lung cells (V79 cells) which effect with two main district of China and four alternative chrysotile fiber to investigate the factors of lung cancer. V79 cells were exposed to the suspension of Chrysotile and its substitute with different powder content, the survival rate of cells was monitored by MTT. After 48 h, the location, distribution and expression of Survivin, Cap43, Bcl-2, p16 and p53 in V79 cell were examined by immunohistochemistry and compared. In the six kinds of powder, the inhibition of rockwool on the growth of cells was weakest, the inhibition of Chrysotile from Xinkang Sichuan and Southern Shanxi on the growth of cells was strongest. Chrysotile from Xinkang Sichuan, Chrysotile from Southern Shanxi, glass fiber, ceramic fiber, rockwool and wollastonite had a certain influence on the survival rate of V79 cells. As the concentration of powder increased the survival rate of cells decreased, which showed dose-effect relationship. The expression of Survivin, Cap43 and Bcl-2 was upregulated and the expression of P16 and P53 was downregulated in V79 cells, which was obviously in the powder suspension of Chrysotile from Southern Shanxi and Xinkang Sichuan and glass fiber. The expression was mainly in cytoplasm. The influence of different kind of powder on the cells differed in degree. Chrysotile and its substitute can induce the development of cancer by upregulating the expression of Survivin, Cap43 and Bcl-2 and downregulating the expression of p16 and p53.
