Relationship between hyperuricemia and metabolic syndrome

Objective: To investigate the relationship between metabolic syndrome and hyperuricemia. Methods: A total of 2 374 subjects who received health examination in our hospital from Jan. 2004 to Dec. 2006 were enrolled in our study. Hyperuricemia is defined as ≥7 mg/dl (in men) or ≥6.0 mg/dl (in women). Metabolic syndrome was defined using AHA/NHLBI (American Heart Association/National Heart, Lung, and Blood Institute) criteria. Results: (1) The overall prevalence of hyperuricemia was 13.10%. The condition was more common in men than in women (19.07% vs 3.42%). (2) Among men, uric acid concentration is statistically significantly positively correlated with waist circumference, blood pressure, and triglyceride. Uric acid is negatively correlated with serum high-density lipoprotein-cholesterol (HDL-C). Uric acid concentration is most strongly correlated with serum triglyceride (r=0.379) and waist circumference (r=0.297). Among women, statistically significant positive correlations were noted for the serum uric acid concentrations with waist circumference, triglyceride and fasting plasma glucose. Serum triglyceride (r=0.329) and waist circumference (r=0.234) are most strongly correlated with uric acid concentrations. (3) Men with hyperuricemia had a 1.634-fold increased risk of metabolic syndrome as compared with those without hyperuricemia odds ratio (OR)=1.634, P=0.000. Women with hyperuricemia had a 1.626-fold increased risk of metabolic syndrome (OR=1.626, P=0.000) as compared with those without hyperuricemia. Conclusion: Hyperuricemia is prevalent among Chinese population. Additionally, serum uric acid is positively associated with metabolic syndrome.     

民族高校细胞生物学实验教学改革探索

为了进一步培养民族高校学生的实验技能,在细胞生物学实验课程教学中,实验课教学小组通过不断改革教学方法,适应新的教学体系,及时调整实验教学内容和形式,以及建立完善的成绩评定体系,把好教学质量关,充分发掘学生的潜能,增强学生学习的自信心和兴趣,从而达到提高学生实验技能的目的.通过对近4年的细胞生物学实验成绩的分析,结果显示,实验对绝大多数学生在提高专业技能、培养独立工作能力、提高分析问题和解决问题能力、提高自主学习意识和能力、增强团队协作意识等方面有很大帮助.

论民主教育的目的与原则——自由主义政治哲学的视角

自治与权利平等是民主的基本属性。作为政治制度的民主,赋予公民平等的权利,信任公民的自治能力。民主的属性决定了民主教育不仅仅是一种公民教育,其根本目的是促使人成为自由、平等的人。民主的属性与价值追求决定了民主教育需要遵循自由原则、平等原则和教育与生活相统一原则。     

“序换”格续貂

根据谭永祥先生1983年首创的序换辞格论述,结合近期的语言材料,用吴士文辞格结构理论,对序换格进行了分析研究。以语法单位为标准划分出序换格的类别,并归纳出序换格的修辞作用,从而进一步认识这个比较常见常用的修辞手段。

学前师范类高职高专化学教学困境与对策探讨

学前师范教育专注于培养幼儿教师,使幼儿教师能够通过不同的方法、实物,系统化地对幼儿进行教育。高等职业教育学院和高等专科学科教育的师范类专业,是培养实用型幼教人才的重要基地。在培养幼儿教师的各类课程中,化学是非常重要的一门课程,高职高专应重视对化学教师的教育改革问题。本文对学前师范类高职高专化学教育的困境提出合理建议,为其未来发展寻求新的出路。     

Development of a space cold atom clock

Atomic clocks with cold atoms play important roles in the field of fundamental physics as well as primary frequency standards. Operating such cold atom clocks in space paves the way for further exploration in fundamental physics, for example dark matter and general relativity. We developed a space cold atom clock (SCAC), which was launched into orbit with the Space Lab TG-2 in 2016. Before it deorbited with TG-2 in 2019, the SCAC had been working continuously for almost 3 years. During the period in orbit, many scientific experiments and engineering tests were performed. In this article, we summarize the principle, development and in-orbit results. These works provide the basis for construction of a space-borne time-frequency system in deep space.     

集训对舞龙队女大学生血常规及内皮祖细胞的影响

目的:分析舞龙运动对女大学生血常规及内皮祖细胞含量的影响。方法:选取2017级舞龙队女大学生10人为训练组,2017级普通女大学生10人作为对照组。舞龙队女大学生备战比赛进行连续4周,每周3次,每次90min的赛前集训,普通女大学生除日常活动外,没有额外进行任何其他运动队的集训。集训结束后,在受试者都处于空腹状态下对两组受试者进行静脉采血并进行血常规、早期内皮祖细胞和晚期内皮祖细胞的检测。所得数据进行统计学分析。结果:参加舞龙集训的女大学生的血常规指标与普通女大学生的血常规指标无显著差异,早期EPCs和晚期EPCs无显著性差异,但在数值上显示出不同的趋势。结论:参加舞龙集训的女大学生身体处于健康状态。参加舞龙集训有可能增强运动员血管的自我修复能力。
