1Seasonal variability in CDOM absorption and fluorescence properties in the Barataria Basin,Louisiana,USA显示文摘Absorption and fluorescence properties of chromophoric dissolved organic matter(CDOM) along a 124 km transect in the Barataria Basin,a large estuary located in Louisiana,USA,were investigated during high and low flow periods of the Mississippi River in the spring and winter of 2008-2009. Mean CDOM absorption at 355 nm from the marine to the freshwater end member stations ranged from(3.25 ± 0.56) to(20.76 ± 2.43) m-1 for the three month high flow period whereas it varied from(1.48 ± 1.08) to(25.45 ± 7.03) m-1 for the same stations during low flow period. Corresponding salinity values at these stations indicated the influence of river and shelf exchanges in the lower basin and precipitation and runofl in the upper basin. An inverse relationship of CDOM absorbance and fluorescence with salinity observed in the basin could be a useful indicator of salinity. CDOM fluorescence also varied over a large range showing an approximately 8 to 12-fold increase between the marine and freshwater end members for the two flow seasons. Excitation-emission matrix spectral plots indicated the presence of various fluorescence components with highest being the A-peak,lowest the T-peak,and the C and M-peaks showing similar trends along the transect. During low flow season the A/C ratio were well correlated with station locations indicating increased terrestrial influence towards the upper basin. CDOM absorption and fluorescence at 355 nm were highly correlated and independent of CDOM sources suggesting that fluorescence could be used to characterize CDOM in the basin.Shatrughan Singh Eurico D'Sa Erick Swenson 2010Journal of Environmental Sciences2010,22,10:8
2曲马多治疗糖尿病性神经疼痛的双盲随机试验显示文摘目的 :本研究旨在评价曲马多治疗糖尿病性神经痛的有效性和安全性。背景 :糖尿病性神经痛是糖尿病患者的主要症状 ,其治疗和其他的末梢神经病变一样 ,不能令人满意。曲马多是作用于中枢的镇痛剂 ,用于治疗中到重度疼痛。方法 :多中心、门诊病例、随机、双盲、安慰剂做对照、设置平行组的研究 ,包括清洗期 (在此期间停用所有镇痛剂 )和一个为期 42天的双盲治疗期。总共有 1 31名患糖尿病性神经痛的患者按每日 4次接受了曲马多 (n =65)或看上去与曲马多相同的安慰剂胶囊治疗 (n =66)。 42天的治疗结束后或治疗中断后比较曲马多组和安慰剂组平均疼痛强度评分作出主要有效性分析 ;次要有效性分析为疼痛缓解率评分和根据日常活动和睡眠状况作出的对生活质量的评估。结果 :曲马多平均剂量为 2 1 0mg/天 ,治疗糖尿病性神经痛较安慰剂有显著疗效 (P≤ 0 .0 0 1 )。曲马多组患者生理(P =0 .0 2 )和社会功能 (P =0 .0 4 )的评分显著优于安慰剂组。未发现对睡眠有显著治疗作用。曲马多最常见的不良反应是恶心 ,便秘 ,头疼和嗜睡。结论Harati Y Gooch C Swenson M Green D Raskin P Donofrio P Cornblath D Sachdeo R Siu CO Kamin M 2001中国疼痛医学杂志2001,7,1:2
