经直肠超声引导前列腺靶向活检的应用进展

超声引导下系统性活检为目前前列腺癌诊断的金标准，然而由于系统性穿刺难以定位病灶，因此阴性率较高。近年来，随着新技术的发展，前列腺靶向穿刺活检越来越多的应用于临床。本文就前列腺靶向活检的临床应用进展做一综述。     

目标教学在前列腺超声诊断技术带教中的应用价值研究

目的探讨目标教学在前列腺超声诊断技术带教中的应用效果。方法选择2017年1月-2018年12月于我院进行前列腺超声诊断技术培训的影像学专业学生80例,根据入院时间先后顺序分为研究组与对照组,每组40例。对照组医学生采用常规教学法带教,研究组医学生采用目标教学法带教,比较两组带教效果。结果研究组医学生的超声诊断仪使用(94.12±2.73)分、超声扫查技巧(92.81±5.06)分、操作技能(90.83±5.11)分、超声图像表现掌握(91.96±3.67)分均高于对照组(P<0.05)。研究组医学生的总体满意度CEQ评分(8.22±0.24)分高于对照组的(5.25±0.30)分,两组比较差异具有统计学意义(P<0.05)。结论目标教学在前列腺超声诊断技术带教中的应用效果良好,可有效提高医学生的操作能力,提高医学生对带教模式的肯定度。     

拂尘落花

正芙蓉树繁枝成荫,花漫绿叶间。远望去若粉雪落枝。信步树下,仰慕一树花开,不禁驻足不前,那纤若细丝的花瓣,无风时,静如一幅淡定的水粉画;微风掠过,袅娜微摆,宛如翩若惊鸿的灵动,无须故作姿态却亦妩媚自生。俯身拾起一枚飘落的芙蓉花,这树上开的花果然与别花不同。尘世间的百花,哪个不是花瓣相拥,花蕊玉立。唯有这芙蓉,花     

某部官兵3km体能训练前后血尿酸等水平变化观察

目的:观察某部官兵3km体能训练前后血尿酸(SUA)、肌酸激酶(CK)和肌酸激酶同工酶(CK-MB)水平变化。方法:选择参加年度体能训练的某部官兵483例,检测前均至少3个月未进行长跑训练。分别于训练前、训练后即刻、训练后6h、训练后24h、训练后48h,取静脉血测定其SUA、CK和CK-MB水平,分析其变化趋势及与年龄、性别、体重的关系。结果:3km体能训练后即刻,SUA水平非常显著高于训练前(P<0.01);训练后即刻及训练后6h、24h,血CK水平显著或非常显著高于训练前(P<0.05,P<0.01);训练后即刻及训练后6h,血CK-MB水平显著或非常显著高于训练前(P<0.05,P<0.01),年龄、性别、体重亦是重要影响因素。结论:年度首次3km长跑体能训练对血SUA、CK和CK-MB水平有显著影响,应注意及时充分休息,避免引起肾、骨骼肌及心肌的持续损害。     

急性心血管事件院前急救的应急策略及流程探讨

Objective To study the strategy and process of out-hospital emergency care of acute cardiovascular events. Methods One hundred and eighty-three patients in the Second Affiliated Hospital of Baotou Medical College were prospectively studied. The patients were divided into two groups according to the different ways of out-hospital care, one group consisted of patients who received first-aid care after calling " 120" (94 cases), another was self-aid group consisting of patients sent to hospital by relatives (89 cases). The proportion of persons with higher than high school education and better knowledge for emergency care of patients with heart disease in first-aid group was higher than self-aid group (50. 0% vs. 29. 2%, 83.0% vs. 60. 7%, both P<0. 05). When the patients were brought to the emergency room, they were all treated according to our standard procedure and then registered. All patients were followed up at the end of first and third month after illness. Results Cardiovascular events were mainly myocardial infarction (61.7%) among 183 patients. There were statistically significant differences between two groups in self-aid response time, first disposal time and out-hospital rescuing time [(32.3 ± 5.6) minutes vs. (89.6±8.4) minutes, (47.3±7.3) minutes vs. (149.8±13.5) minutes, (61.7±8.3) minutes vs. [(149.8±13.5) minutes, all P<0. 01], but no difference was found in in-hospital rescuing time [(29. 9±5.3) minutes vs. (31.1±4.5) minutes, P>0. 05]. Morbidity rate was lower in first-aid group than self-aid group in 1st and 3rd month, respectively (2.1% vs. 9. 0%, 4. 2% vs. 12.4%, both P<0. 05). Conclusion Excellent emergency system and procedure can shorten initial disposal time and out-hospital rescuing time, thus improve patients' prognosis. The education level and health knowledge of patients and their raletives directly affect their mode of arriving hospital and prognosis.

氧气湿化液应用及预防污染的研究进展

氧气疗法（简称氧疗）是临床上常用的一种护理技术及抢救治疗手段。氧气湿化液在氧疗中起湿化作用,避免干燥的氧气刺激呼吸道黏膜,以提高氧疗效果和患者的舒适度。文献报道,氧气湿化液是导致氧疗患者院内感染频发的原因之一。     

＂比＂字最残酷

汉语里“比”字最残忍，因为是两把匕首并肩走，左边的藏在鞘里，暗藏杀机；右边的明晃晃地亮出来，让人不寒而栗。生活中，“比”这件事最残酷，它可以比掉人的自信，比丢人的幸福感。甚至因攀比不过，心生嫉恨，产生邪念。

茶水红颜

若茶以水为母,拜器为父,那么生命因此缘起,茶水亦应得一知己,情深之处只为伊人。托腮凝思,谁才是茶水的倾心红颜。 朝暮相处,两情依依,唯有筝曲与茶情意浓浓。试想独自品茶,纵使茶舞清杯,还是少去几许韵味。纵使清茶入口,口舌生津,也难免滋生寂寥,且耳鼓愈发倍感孤寂。而独赏筝乐,心灵与之轻重缓急,宛若过高山,轻流水,可是不知目光该落何处,手足该如何搁置,才不辜负了这婉转美妙的清音。
