This study was conducted to identify the origin, hydrogeochemical processes and evolution of groundwater in a tectonic valley. This study was carried out with the aim of quantifying the proportions of groundwater flows contributing to the water chemistry abstracted in a zone of convergence favored by the presence of active faults. The study area is located in the Trans-Mexican Volcanic Belt. End members methodology was applied to identify the mixing of hydrothermal with fresh groundwater, where changes in the aquifer geology result in distinct groundwater chemical signatures. Ternary mixing was quantified using conservative elements. Moreover, other evolutionary processes, such as ion exchange and silicate weathering occur due to changes in the geology of the area. In ternary mixing, each of the end members is associated with the lithology through which it circulates. The local flow contributes 70% of the water to the system, the intermediate flow contributes 14%, and the regional flow contributes 16%. Three types of water are produced: na-HCO3, due to the interaction of water with volcanic rocks of rhyolitic composition, na-Mg-HCO3, due to the interaction of water with volcanic rocks of basaltic-andesite composition, and Ca-HCO3, due to the interaction of water with sedimentary calcareous rocks.

目的探讨3种七氟烷吸入麻醉诱导方式的临床效果。方法诱导开始前，打开七氟烷挥发罐，根据分组情况不同，分别选定9％（A组、B组）和4％（C组），同时氧流量3 L/min预充连接管道。完成后，A组（肺活量呼吸法）嘱咐患者尽力呼气后，面罩紧密置于口鼻部，再尽力吸气，并且连续用肺活量呼吸方式呼吸数次；B组（潮气量呼吸法）将面罩紧密置于患者口鼻部，嘱咐患者正常呼吸；C组（逐渐增加浓度法）用4％七氟烷预充连接管道后，将面罩紧密置于患者口鼻部，嘱咐患者正常呼吸，每25秒增加七氟烷吸入浓度1．5％。设定潮气量为7～9 mL/kg ，呼吸频率为13次/min ，异丙酚60～90μg/kg · min静脉泵注射进行麻醉维持，同时可加用瑞芬太尼0．2～0．3μg/kg · min。结果 A组、B组和C组在不同时间点的收缩压、舒张压和平均压力都得到了抑制（P＜0．05），并且在时间点T3抑制效果显著（P＜0．01）。A组、B组和C组在不同时间点与心率变化和肌肉松弛效果无密切关联（P＞0．05）。结论通过实验得出3种不同浓度和吸入方式的七氟烷吸入诱导方式均能取得理想的临床效果，都体现出了七氟烷诱导快、刺激性小、对血流动力学影响较平稳的优点。

在地理学、生态学、景观生态学等相关学科知识的影响下,美国、加拿大、欧洲等西方国家的风景园林规划设计方法及样式均出现了生态化的转向。通过文献研究及实地踏勘,对西方近现代风景园林设计的美学价值取向及审美观的变化进行了系统性地梳理,揭示了风景园林美学范式转向的背景、过程,以及对风景园林设计样式的影响,并在此基础上探寻了新世纪风景园林美学可能的发展趋势。推演的结果表明,在新世纪美学运动的影响下,西方近现代风景园林美学由人文主义、古典主义、浪漫主义、现代主义美学转向了生态主义美学,并将发生伦理化美学的范式转向。

Although inter-laboratory validation efforts of the flow cytometry(FCM) based in vivo micronucleus (Mn) assay have taken place in the EU and US,none have been organized in China.

Objective: To assess the effect of using 2 throat swabs vs 1 on rapid detectio n of group A streptococcus by the STREP A OIA MAX (hereafter, OIAMAX) test. meth ods: Children aged 5 to 18 years with acute pharyngitis were randomizedto 1 of 2 study groups. In group 1, one throat swab was obtained, streaked first on sheep blood agar, and then used for OIA MAX testing. In group 2, two throat swabs wer e obtained simultaneously. One swab was streaked first on sheep blood agar and t hen joined with the other swab for OIA MAX testing. In both groups, the pledgets in the collection-transport tube were incubated in Todd-Hewitt broth. A posit ive group A streptococcus culture either by sheep blood agar or Todd-Hewitt bro th was confirmed by a latex agglutination test. Results: Three hundred sixtythre e patients were enrolled, 177 in group 1 and 186 in group 2. Cultures were posit ive for group A streptococcus in 154 (42.4%) of 363 patients. The sensitivity a nd specificity of OIA MAX testing were 94.7%and 100.0%, respectively, in group 1, and 92.4%and 96.3%, respectively, in group 2. There was no statistical dif ference between the sensitivity, the specificity, and the predictive values of t he OIA MAX test performed with 1 swab compared with those performed with 2 swabs (P>.10). There was no association between OIA MAX test sensitivity and the seve rity of pharyngitis as measured by the modified Centor criterion (history of fev er, absence of cough, presence of pharyngeal or tonsillar exudates, and presence of cervical lymphadenopathy) scores. Conclusions: The OIA MAX test yielded comp arable sensitivity and specificity in both study groups. The use of 2 throat swa bs instead of 1 swab did not increase the sensitivity of the OIA MAX test. The p erformance of the OIA MAX test did not depend on the severity of pharyngitis.
