少数民族地区自治与发展关系的哲学思考

发展与自治是少数民族地区的两个重要主题，发展离不开自治，自治推动和促进民族地区的发展，离开发展谈自治是错误的，同样，离开自治谈发展也是不正确的。当前，民族地区应当加强自治制度的建设，加快各项事业发展的步伐。     

Synergistic effect of acute hypoxia on flow-induced release of ATP from cultured endothelial cells

Human umbilical vein endothelial cells (HUVECs) in primary cultures were perfused under normoxic or hypoxic conditions. These cells were stimulated twice for 3 min by increased flow (from 0.5 to 3.0 ml/min). Under hypoxic conditions the basal release of ATP was the same as under normoxic conditions, but during increased flow the release was greater (0.58±0.07>0.32±0.04 pmoles/ml/10⁶ cells (+78%), for the first period of stimulation; 0.39±0.05>0.22±0.03 pmoles/ml/10⁶ cells (+79%) for the second period). Further experiments with sequential increments in flow rate showed that under both normoxic and hypoxic conditions, a positive correlation existed between ATP release and the rate of flow but there was always more ATP released under hypoxic conditions regardless of the flow rate.HUVECs in secondary culture (second passage) were similarly stimulated. No differences were observed between normoxic and hypoxic conditions. In both cases, the quantity of ATP released during high flow (0.050±0.004 pmoles/ml/10⁶ cells) was significantly smaller than the quantity of ATP released during low flow (0.09±0.01 pmoles/ml/10⁶ cells).To conclude, since hypoxia alone did not affect ATP release, there appears to be a synergistic relationship between increased shear stress and hypoxia in the stimulation of ATP release from HUVECs. Moreover, the release of ATP under these conditions seems to be a property of highly differentiated endothelial cells.

补充丙酮酸盐对运动能力的影响

用文献资料法、对比法、逻辑分析法等研究了补充丙酮酸盐对身体一般功能和运动能力的影响.结果表明:丙酮酸盐补充可以降低体重和增加利用脂肪供能;有关丙酮酸盐补充对身体其他机能的影响也有报道,但仅有一些初步的证据证明它在运动员中使用的有效性;丙酮酸盐补充对人体影响的机制和有效性还有争议,推荐运动员使用丙酮酸盐的剂量还不明确.     

Ultrastructural localisation of substance P and choline acetyltransferase in endothelial cells of rat coronary artery and release of substance P and acetylcholine during hypoxia

Substance P and choline acetyltransferase have been localised in a small proportion of endothelial cells of rat coronary arteries using electron microscopic immunocytochemistry. During a hypoxic period of 1 min, coronary vasodilatation was produced in the Langendorff heart preparation and increased levels of substance P and acetylcholine were released into the perfusate. The possibility that these substances are released from endothelial cells during hypoxia and contribute to the hyperaemic response is discussed.

耐力运动对尿成分影响的测评分析

本文通过文献资料法、实验测试法、数理统计法及逻辑分析法对耐力运动前后的尿样成分进行测试、统计和分析,结果发现耐力运动可导致尿成分发生改变,且运动前、后及次日晨尿三组尿样成分具有显著性差异（P〈0.01）,在运动后次日的尿成份检测中发现因运动负荷过大,部分测试对象处于疲劳状态,未能完全恢复。

对体育锻炼和认知干预提高贫困大学生心理健康的探究

通过心理量表、问卷、试验干预和数理统计等方法对贫困大学生进行调查，试验研究发现：认知行为疗法较体育锻炼能更有效地提高贫困生的心理健康；体育锻炼和认知行为疗法手段的综合运用，比单一采用一种干预方式也更加有效。并提出了一些解决贫困生心理健康的建议。
