Influence of the spray adjuvant on the toxicity effects of a glyphosate formulation

In the present study, the influence of the spray adjuvant on the toxicity effects of a glyphosate formulation was examined in HEp-2 cell line. We determined the median lethal concentration (LC₅₀) of Atanor® (glyphosate formulation), Impacto® (spray adjuvant) and the mixture of both agrochemicals. We also compared the toxicities of the pesticides individually and in mixture and we analyzed the effects on oxidative balance from each treatment.Our results showed that all the agrochemicals assayed induce dose and time-dependent cytotoxicity and that the toxicity of Impacto® with Atanor® (mixture) was additive on HEp-2 cell line.All the agrochemicals assayed produced an increase in catalase activity and glutathione levels, while no effects were observed for superoxide dismutase and glutathione-S-transferase activities. We found an important increase in ROS production in cells treated with Atanor® and mixture. Besides, all the agrochemicals used triggered caspase 3/7 activation and hence induced apoptosis pathway in this cell line. In conclusion, our results demonstrated that the addition of adjuvant to glyphosate formulation increase the toxicity of the mixture in cell culture. Furthermore, cell culture exposed to agrochemical mixture showed an increased ROS production and antioxidant defenses.     

不同剂量阿托伐他汀在症状性颅内动脉粥样硬化性狭窄中的影像学评估

目的 观察不同剂量阿托伐他汀在症状性颅内动脉粥样硬化性狭窄（intracranial arterial stenosis,ICAS）中的疗效。方法 选择120例症状性ICAS患者,采用随机表法,分为低剂量组（10 mg/d）、标准剂量组（20 mg/d）和强化组（40 mg/d）,每组患者各40例。临床随访52周,观察治疗前后脑血流灌注值及血管狭窄程度的变化,评价强化降脂疗效。结果 三组在治疗后26周和52周,相对脑血流量（rCBF）、相对脑血容量（rCBV）较治疗前均明显升高;低剂量组和标准剂量组相对达峰时间（rTTP）与治疗前比较,均有不同程度的延长,但差异无统计学意义,强化组rTTP与治疗前比较明显缩短,差异有统计学意义;强化组平均狭窄率与治疗前相比明显降低,与治疗后低剂量组和标准剂量组相比差异也有统计学意义。结论 长期他汀强化降脂治疗（40 mg/d）可以降低颅内动脉狭窄程度及提高脑血管的血流灌注。

Effects of Statins on High-Density Lipoproteins: A Potential Contribution to Cardiovascular Benefit

PURPOSE: The objective was to systematically review clinical trial data on the effects of statins on high-density lipoproteins (HDL) and to examine the possibility that this provides cardiovascular benefits in addition to those derived from reductions in low-density lipoproteins (LDL). METHODS: The PubMed database was searched for publications describing clinical trials of atorvastatin, pravastatin, rosuvastatin, and simvastatin. On the basis of predefined criteria, 103 were selected for review. RESULTS: Compared with placebo, statins raise HDL, measured as HDL-cholesterol (HDL-C) and apolipoprotein A-I (apo A-I); these elevations are maintained in the long-term. In hypercholesterolemia, HDL-C is raised by approximately 4% to 10%. The percentage changes are greater in patients with low baseline levels, including those with the common combination of high triglycerides (TG) and low HDL-C. These effects do not appear to be dose-related although there is evidence that, with the exception of atorvastatin, the changes in HDL-C are proportional to reductions in apo B-containing lipoproteins. The most likely explanation is a reduced rate of cholesteryl ester transfer protein (CETP)-mediated flow of cholesterol from HDL. There is some evidence that the statin effects on HDL reduce progression of atherosclerosis and risk of cardiovascular disease independently of reductions in LDL. CONCLUSION: Statins cause modest increases in HDL-C and apo A-I probably mediated by reductions in CETP activity. It is plausible that such changes independently contribute to the cardiovascular benefits of the statin class but more studies are needed to further explore this possibility.

川芎平喘合剂治疗支气管哮喘急性发作期患者临床疗效及对炎性因子水平的影响

目的探讨川芎平喘合剂对支气管哮喘急性发作期患者血清炎性因子水平的影响。方法将66例哮喘急性发作期患者随机分为2组。对照组给予西医常规治疗,治疗组在常规治疗基础上给予川芎平喘合剂,每次20 mL,每日3次。疗程均为14 d。观察2组临床疗效及治疗前后肺功能的变化,采用酶联免疫吸附法（ELISA）检测血清肿瘤坏死因子（TNF-α）、白细胞介素-6（IL-6）水平。结果治疗组临床疗效优于对照组,但无明显差异。经治疗,治疗组咳嗽、喘息、胸闷、气短症状积分明显低于对照组（P〈0.05）,血清TNF-α、IL-6水平均较对照组明显下降（P〈0.05）,1秒用力呼气容积（FEV1）、呼气峰值流速（PEF）改善均优于对照组（P〈0.05）。结论川芎平喘合剂具有缓解哮喘急性发作期患者临床症状、改善肺功能的作用,其机制可能与降低体内TNF-α、IL-6过度表达,抑制炎性反应有关。
