Body composition,work capacity,and work efficiency of active and inactive young men

On 46 healthy young men, of whom 18 took part in strenuous sport at least once a week, height, weight, total body fat (as % of body mass) and lean body mass (LBM) were determined. The subjects performed submaximal exercise on a bicycle ergometer and climbing on an upwardly inclined treadmill at work loads of 60, 110, and 140 watts. Oxygen consumption ( ), respiratory quotient (RQ), energy expenditure (), and heart rate (f _H) were measured at rest and at each work load, and maximum oxygen intake ( max) and physical work capacity (PWC₁₅₀, PWC₁₇₀) were calculated.Anthropometric parameters did not differ significantly between sportsmen and sedentary subjects. max, PWC₁₅₀, and PWC₁₇₀ had higher correlations with LBM than with the other anthropometric parameters. max expressed in terms of LBM (ml/kg LBM/min) was the parameter which showed the clearest distinction between sportsmen and sedentary individuals. The sportsmen had higher max on the treadmill test than on the bicycle ergometer. PWC₁₅₀ and PWC₁₇₀ were higher on the bicycle than on the treadmill and had high correlations with max. Work efficiency was of the same order in both groups and showed negative correlation with the degree of obesity on the bicycle ergometer and positive correlation on the treadmill.

磁性阿霉素纳米微球的制备及在高频磁场中的发热研究

制备一种在高频磁场中能感应发热的用于治疗肿瘤的阿霉素纳米微球，研究其在磁场中的热效应。用超声搅拌冷冻干燥的方法制备药物微球，平均粒径200nm左右。电镜观察其形态为球囊状。将其置于不同介质中于高频磁场中测其温度变化值，实验表明该微球在交变磁场中使介质升温。升温速度与平稳时的温度和微球的量及磁场强度成正比，介质流动性好，升温快。     

Group treatment for pain and discomfort

Rheumatic patients very often suffer from chronic pain and impairment and show psychological reactions as a consequence of their physical condition. These reactions may vary from psychophysiological symptoms to anger, anxiety, or depression. We developed a cognitive-behavioral treatment programme in a group setting format with components of relaxation, cognitive restructuring, and the promotion of well-being. Subjects included in the study were given diagnoses of low back pain, tension headache, rheumatoid arthritis, and ankylosing spondylitis. Treatment effects in different diagnostic groups were compared to each other, supporting the assumption that pain reduction is greatest in low back pain and least in ankylosing spondylitis. Subjects with inflammatory rheumatic diseases showed some improvement in self-reported physical complaints and in their feelings of well-being.     

Effect of megestrol caproate on the reproductive function of laboratory animals

In vivo experiments on rats and rabbits showed that megestrol caproate, a 17-alpha-hydroxyprogesterone derivative exhibits 10-fold higher gestagenic activity compared to progesterone and possesses no androgenic, anabolic, and estrogenic activities.     

评“McCall观察方法”——对一种色谱系统分配效果观察方法的商榷

本文通过理论分析和文献数据的分析,对McCall提出的色谱系统分配效果的观察方法提出了不同的看法,认为McCall方法中的所谓logK并不是常数。McCall的方法无论在理论上和实践上都是不妥的。     

正常分娩综合性实验在产科护理教学中的应用研究

目的探讨在产科护理教学中应用正常分娩综合性实验教学取得的效果研究。方法选取2018年9月—2019年6月在该院实习120名护理本科生作为研究对象,依据奇数偶数分配原则分为两组,其中对照组60名学生进行常规的消毒操作和外阴清洁考核,观察组的60名学生应用正常分娩综合性实验进行考核,对比两组学生护理技能测试成绩以及取得的教学效果。结果观察组优良率(98.33%)高于对照组(88.33%),差异有统计学意义(P<0.05);观察组团队协作能力、学习兴趣、解决问题能力、沟通能力及操作能力评分高于对照组,差异有统计学意义(P<0.05)。结论产科护理教学中应用正常分娩综合性实验教学取得的效果显著,能提升教学成绩,让实习护理本科生更快掌握护理技巧,为医院输送优质护理人才,能缓解产科护理人员缺乏的现象,正常分娩综合性实验教学方案值得应用。     

自我角色认同护理在躁狂症护理中的应用效果分析

目的探讨自我角色认同护理在躁狂症中的应用效果。方法选取2017-2019年沈阳市铁西区精神卫生中心收治的成人躁狂症发作期患者50例,随机分为对照组和干预组各25例。对照组给予常规护理,干预组给予自我角色认同护理。分别采用激越行为量表和社交技能量表对两组的干预效果进行评价。结果干预后两组激越行为量表和社交技能评定目录量表各维度评分及总分差异均有统计学意义(P<0.05)。结论自我角色认同护理能进一步改善躁狂症患者的激越行为和社交技能,值得临床推广应用。     

多学科协作诊疗助力直肠癌手术质量提升

目的探讨多学科协作诊疗在直肠癌手术中的开展成效。方法将进入多学科协作的患者和未进入多学科协作的患者分别设为观察组和对照组,通过多项指标量化分析直肠癌多学科协作开展成效。结果观察组的术后住院时长短于对照组,差异有统计学意义（P<0.05）;术后首次下床时间短于对照组,差异有统计学意义（P<0.05）;手术总费用、检查费、床位费少于对照组,差异有统计学意义（P<0.05）。观察组低位直肠癌手术有效保肛率高于对照组;在术后早期并发症中,观察组病例数少于对照组;在Ⅲ期直肠癌患者术后无进展生存时间上,观察组要高于对照组,差异有统计学意义（P<0.05）。观察组在生存量表总分、生理领域、心理领域得分均高于对照组,差异有统计学意义（P<0.05）。结论多学科协作在直肠癌诊疗中效果明显,能够确保直肠癌患者手术安全,缩短术后住院时长,降低手术费用,并减少术后并发症发生率,提升低位直肠癌有效保肛率,延长Ⅲ期直肠癌患者术后无进展生存时间,改善患者生存质量。
