《智血》中的圣经文学传统探究

作为一名天主教作家,奥康纳深受圣经文学的影响,在创作过程中援引了大量圣经文学资源。在长篇小说《智血》中,奥康纳将圣经文学中的U形叙事结构,血、光、石头、路等意象以及罪恶与救赎的主题巧妙而完美地融入作品中。主人公黑兹尔的罪与赎之路也因此有了特殊的意义。     

浅析运动强度对运动员血氨值的影响及相关研究

血氨作为一项新的运动生化检测指标已经广泛应用到体育实践中,尤其是在体育科学领域受到了广泛关注。针对我院20名足球专项运动员进行了两次不同运动强度的训练:短跑—400m全速跑;足球赛—90min的足球对抗赛。实验结果表明:运动员完成相应负荷运动后血氨值显著高于安静状态测值(P<0.01),表明其与运动强度的高度相关性。实验结果提示:血氨指标能够较精确地评价运动员的运动负荷强度、机体的机能状态、疲劳程度及恢复情况。

Assessment of glycemic potential of<Emphasis Type="Italic">Musa paradisiaca</Emphasis> stem juice

The present study reveals the effect of Musa paradisiaca stem juice on blood glucose level (BGL) of normal & diabetic rats. The dose of 500 mg/kg bodyweight produces a significant rise of 28.3% in blood glucose level after 6h of oral administration in normal rats. Whereas, in sub diabetic rats the same dose produces a rise of 16.4% in blood glucose levels within 1h during glucose tolerance test (GTT) and a rise of 16% after 4 h in fasting blood glucose levels of severe diabetic cases. These results were unexpected and important to report as other species of Musa like Musa sapientum has been reported for its hypoglycemic effect.     

6周有氧运动改善不同程度肥胖青少年体质健康的研究

目的:研究有氧运动对不同程度肥胖青少年形态、机能、糖脂代谢及身体素质的影响,探索非医疗运动手段治疗青少年肥胖的可行性方法。方法:招募50名13~19岁肥胖青少年,依据BMI值分别纳入中度或重度肥胖组,每组25人。两组受试者进行6周有氧运动(5days/week,50min/day),在运动前、运动3周和6周后分别测试受试者的身体形态、基础生理机能、糖脂代谢和身体素质等指标,并对以上数据进行统计学分析。结果:3周和6周运动均显著降低两肥胖组的体重、BMI、腰围、臀围、脂肪量、体脂率、血脂、甘油三酷、血清胰岛素水平和胰岛素抵抗指数(P＜0.05或P＜0.01),下调重度肥胖组的低密度脂蛋白水平(P＜ 0.01),提高两组肺活量、肺活量指数和50 m跑、俯卧撑、坐位体前屈成绩(P＜ 0.05);6周运动还能进一步提高两组的1 000 m跑、平衡能力以及重度肥胖组的瘦体重和高密度脂蛋白水平(P＜0.05或P＜0.01),下调两组的基础代谢率(P＜0.05)。结论:3周有氧运动就能有效改善肥胖青少年的体质健康,运动改善体质健康的效应呈时间依赖性增加的模式,并且重度肥胖者相比中度肥胖者对有氧运动更加敏感。     

Blood lactate response and critical speed in swimmers aged 10–12 years of different standards

It has previously been shown that measurement of the critical speed is a non-invasive method of estimating the blood lactate response during exercise. However, its validity in children has yet to be demonstrated. The aims of this study were: (1) to verify if the critical speed determined in accordance with the protocol of Wakayoshi et al. is a non-invasive means of estimating the swimming speed equivalent to a blood lactate concentration of 4 mmol·l^-1 in children aged 10-12 years; and (2) to establish whether standard of performance has an effect on its determination. Sixteen swimmers were divided into two groups: beginners and trained. They initially completed a protocol for determination of speed equivalent to a blood lactate concentration of 4 mmol·l^-1. Later, during training sessions, maximum efforts were swum over distances of 50, 100 and 200 m for the calculation of the critical speed. The speeds equivalent to a blood lactate concentration of 4 mmol·l^-1 (beginners = 0.82±0.09 m·s^-1 , trained = 1.19±0.11 m·s^-1; mean±s) were significantly faster than the critical speeds (beginners = 0.78±0.25·s^-1 , trained = 1.08±0.04 m·s^-1) in both groups. There was a high correlation between speed at a blood lactate concentration of 4 mmol·l^-1 and the critical speed for the beginners (r = 0.96, P ? 0.001), but not for the trained group (r = 0.60, P > 0.05). The blood lactate concentration corresponding to the critical speed was 2.7±1.1 and 3.1±0.4 mmol·l^-1 for the beginners and trained group respectively. The percent difference between speed at a blood lactate concentration of 4 mmol·l^-1 and the critical speed was not significantly different between the two groups. At all distances studied, swimming performance was significantly faster in the trained group. Our results suggest that the critical speed underestimates swimming intensity corresponding to a blood lactate concentration of 4 mmol·l^-1 in children aged 10-12 years and that standard of performance does not affect the determination of the critical speed.     

Heart rate and match analysis in pre-pubescent soccer players

The aim of this study was to compare match analysis (using video recordings) and the physiological load (heart rate measured every 5s, blood lactate measured after the warm-up, first half and second half) of six 11-year-old soccer players during official games of eleven-a-side on a regular-sized pitch (100×65m) and of seven-a-side on a smaller pitch (60×40m). In both games, heart rate exceeded 170 beats·min-1 84% of the time, while blood lactate ranged from 1.4 to 8.1 mmol·l-1 . No significant differences were recorded for the physiological parameters. For both matches, walking comprised 38% of total time, running 55%, inactivity 3% and jumping 3%. Although there were no significant differences between halves or matches, running for less than 10s was 10% more frequent in the seven-a-side game. In the seven-a-side game, there were significantly more passes and significantly fewer tackles, suggesting that seven-a-side matches played on smaller pitches may be more suitable for pre-pubescent soccer players.

高血压中医证型与血液指标的相关性研究进展

近些年来关于高血压中医证型与客观血液生化指标的相关性研究广泛开展并已取得一些进展,血液指标能反映出高血压中医辨证分型的分布规律,文章就高血压中医证型与血液指标的相关性研究作一综述,但由于采用的证型缺乏统一性,与高血压发病密切相关的一些血液指标与中医证型相关性研究仍缺乏可比性。     

冰片对血脑屏障P-糖蛋白功能的影响

观察冰片对血脑屏障(BBB)P-糖蛋白功能的影响。取NIH小鼠,随机分为冰片高、中、低剂量组,维拉帕米组和溶剂对照组。灌胃给药,每日2次,共7次。末次给药后,分别从尾静脉和脑室注射罗丹明123(Rho-123)。注射Rho-123后取血浆和脑组织,荧光分光光度法测定血浆及脑组织中Rho-123含量。结果表明:尾静脉注射Rho-123后,冰片对小鼠血浆Rho-123含量无明显影响;5,10,20和30min冰片高、中剂量组小鼠脑组织Rho-123浓度均显著高于溶剂对照组(P0.01)。脑室注射Rho-123后5,10,20和30 min,冰片高剂量组小鼠血浆Rho-123浓度均显著低于溶剂对照组(P0.05);20,30min冰片中剂量组小鼠血浆Rho-123浓度亦显著低于溶剂对照组(P0.05);1,5,10和20 min冰片高剂量组小鼠脑组织Rho-123浓度显著高于溶剂对照组(P0.01或P0.05);5,10 min冰片中剂量组小鼠脑组织Rho-123浓度亦显著高于溶剂对照组(P0.05)。说明冰片能抑制BBB P-gp功能。
