由醉酒驾驶引发的系列恶性交通事故震惊了全社会,强大的民意和社会舆论是醉酒驾驶刑法规范的立法契机。用刑法调整酒后驾驶机动车尤其是醉驾行为是有效保护公民的合法权益和社会公共利益,消除社会的恐慌心理的最佳途径。治理醉酒驾驶犯罪国外有丰富的经验和完备的立法,可资我国借鉴。探究醉酒驾驶刑法规制的依据十分必要,这种法学原理的分析将为立法机关正在进行的规范酒驾犯罪的立法提供理论支持。  相似文献

This study aimed to analyse the association of different components of physical fitness, body composition, cardiometabolic markers and the Mediterranean diet with bone mineral density (BMD) in perimenopausal women, and to test which of these components are independently associated with BMD. The sample comprised 197 perimenopausal women (52.6 ± 4.5 years). Physical fitness was assessed with the “Senior Fitness Test” battery and the handgrip strength and Bruce tests. Fat and lean mass and BMD were measured using dual-energy X-ray absorptiometry. We analysed the markers of metabolic syndrome, C-reactive protein, and components of the Mediterranean diet. Handgrip muscle strength (β = 0.212, P = 0.005), body weight (β = 0.244, P = 0.001), BMI (β = 0.180, P = 0.011) and lean mass (β = 0.379, P < 0.001) were positively associated with BMD. No associations were observed between cardiometabolic markers or the Mediterranean diet with BMD (all P > 0.05). When all relevant indicators of BMD were simultaneously considered, lean mass was the only 1 showing an independent association with BMD (β = 0.392, P < 0.001), explaining 14% of the BMD variability. In conclusion, muscle strength might be a marker of BMD in perimenopausal women. However, lean mass was the only factor independently associated with BMD. Future research to determine whether increasing lean mass through specific exercise-based interventions contributes to increasing BMD is warranted.  相似文献

离子色谱法同时分离测定三种麻黄碱类药物   总被引:2,自引:0,他引:2  
用离子色谱法同时分离测定三种麻黄碱类药物.在Metrohm cation 1-2阳离子交换上,用2.0mmol/L HNO3和1%乙腈混合溶液作为流动相,在20分钟内同时分离测定了麻黄碱、伪麻黄碱和去甲麻黄碱三种药物.去甲麻黄碱在0.08μg/ml-40μg/ml浓度范围内与色谱峰面积成正比麻黄碱、伪麻黄碱在0.2μg/ml-40μg/ml浓度范围内与峰面积成线性关系,线性相关系数分别为0.9996,0.9999,0.9999.去甲麻黄碱的检出限为0.04μg/ml.麻黄碱及伪麻黄碱的检出限均为0.08μg/ml.  相似文献

This study examined drinking motives, alcohol use, and alcohol‐related problems among White college athletes and college athletes of color (N = 113). Results indicated no differences in drinking motives between the 2 groups. White athletes reported higher levels of alcohol use, whereas athletes of color reported higher levels of alcohol‐related problems. Athletes of color with high levels of coping and conformity motives reported the highest level of alcohol‐related problems.  相似文献

酒源于自然界,后来经过人类的加工而成,与社会生活紧密相连,从魏晋隋唐时人们普遍嗜酒可以看出各时代酒风的盛行。回顾酒的历程,它产生过消极作用,蕴含着深刻的治国安邦的道理。鉴于历史教训,统治者们采取了相应的禁酒政策。酒的利弊不是出于本身特性,而是出于人们理性与非理性的选择。  相似文献

在"竹林七贤"中,善于操琴的嵇康与嗜酒如命的刘伶格外引人注目,他们或以"琴"或以"酒"为载体,通过自己一种"特立独行"的行为来表达对司马氏政治重压的无声反抗,体现了追求人格独立、精神自由与解放的"魏晋风度"。  相似文献

Background

It is still uncertain whether or not avoidance to let disinfectant alcohol dry at the site of venipuncture is a source of spurious hemolysis when drawing venous blood.

Methods:

In a consecutive series of 52 outpatients referred for routine laboratory testing, venous blood was drawn by direct venipuncture with (odd group) or without (pair group) wiping 70% isopropyl alcohol at the site of venipuncture. A 3.5 mL evacuated tube with clot activator and gel separator was drawn from a vein of the upper limb, serum was immediately separated with standard centrifugation and tested for potassium, lactate dehydrogenase (LD), aspartate aminotransferase (AST) and hemolysis index (HI) on Roche Cobas.

Results:

No specimen was discarded for unsatisfactory venipuncture. No differences for age and gender were observed between groups. As regards the four parameters investigated, no significant differences could be observed between patients in whom blood was drawn with or without letting the alcohol dry. It is also noteworthy that no sample in both groups exceeded the conventional sample rejection threshold of cell-free hemoglobin.

Conclusions:

The results of our prospective, randomized study attest that failure to wipe alcohol at the site of venipuncture should not be considered as a potential source of spurious hemolysis when drawing blood.  相似文献
