用统计学方法对14年来(1977~1990年)我校6746名新生(13492只眼)的视力状况进行分析。结果表明;新生正常视力逐年减少,视力不良率相应上升(P<0.001)。城市学生的视力比农村学生差,男生的视力优于女生(P<0.001)。17~19岁组的视力明显低于其他年龄组(P<0.001)。高考分数线升高与正常视力者减少呈明显负相关;而与视力不良者增加呈正相关(P<0.001,<0.05)。本文认为近距离用眼持续时间过长及环境视域小等是引起视力不良的主要原因。 相似文献

目的评价规范化的献血健康教育在无偿献血工作中的作用。方法把2001年实施单一、局限、泛化的卫生宣传教育时参加献血的30036名献血者设为对照组;自2002年开始实施规范化的献血健康教育程序两年后即2004年参加献血的47891名献血者定为干预组,对两组无偿献血各项指标及献血者主动退出、延期献血及不宜献血人数进行比较、评价。结果干预组的自愿献血人数、再次献血人数、一次献血400毫升人数、脂肪血人数、献血投诉人数、主动退出人数、延期献血及不宜献血人数等统计结果均明显优于对照组(P<0.01)。结论实施规范的献血健康教育,可有效提高无偿献血工作质量,确保献血者健康,用血者安全。 相似文献

《The Clinical Supervisor》2013,32(3):91-106
This paper attempts to answer the question of why social caseworkers have ongoing supervision by exploring the historical evolution of social work supervision. Supervision has withstood the many changes in the field since its beginning in the late 1800s and has been reinterpreted to fit the prevailing theories guiding practice, thus avoiding obsolescence. Supervision began as an educational device, then evolved into a practice tool, later became a therapeutic method, and then became a separate entity from therapy. 相似文献

BackgroundNeuropsychiatric complications of surgical coronary revascularization are inconspicuous but frequent and clinically relevant. So far, attempts to reduce their occurrence, such as the introduction of off-pump coronary artery bypass (OPCAB) grafting method, have not brought the desired results. The aim of this trial was to determine whether using any of the 2 selected modifications of OPCAB could decrease the incidence of these undesired sequelae.MethodsIn this single-center, assessor- and patient-blinded, superiority, randomized controlled trial, 192 patients scheduled for elective isolated OPCAB were randomized to 3 parallel arms. The control arm underwent “conventional” OPCAB with vein grafts. The first study arm underwent anaortic OPCAB (ANA) with total arterial revascularization. The second study arm underwent OPCAB with vein grafts using carbon dioxide surgical field flooding (CO2FF). Outcomes included the incidence of postoperative delirium (PD) and early postoperative cognitive dysfunction (ePOCD).ResultsThe incidence of PD was 35.9% in the control (OPCAB) arm, 32.8% in the CO2FF arm, and 12.5% in the ANA arm (χ2 [2, N = 191] = 10.17; P = .006). Post hoc tests revealed that the incidence of PD in the ANA arm differed from that in the OPCAB arm (odds ratio [OR], 0.26; 95% confidence interval [CI], 0.09-0.68; P = .002). The incidence of ePOCD was 34.4% in the OPCAB arm, 28.1% in the CO2FF arm, and 9.5% in the ANA arm (χ2 [2, N = 191] = 11.58; P = .003). Post hoc tests revealed that the incidence of ePOCD differed between the ANA and OPCAB arms (OR, 0.20; 95% CI, 0.06-0.58; P < .001).ConclusionsPerforming ANA significantly decreases the incidence of PD and ePOCD compared with “conventional” OPCAB with vein grafts, whereas CO2FF is inconsequential in this regard. These results, which probably reflect decreased delivery of embolic load to the brain in ANA, may have practical applicability in daily practice to improve clinical outcomes. 相似文献

目的通过比较医用棉纸与弹力绷带作为电动气压止血带衬垫的方法,观察不同衬垫材料在电动气压止血带中的应用效果。方法将2018年1月至12月镇江市中西医结合医院骨科收治的100例患者采用随机数字表分为弹力绷带组(50例)和棉纸组(50例),分别采用弹力绷带和医用棉纸作为电动气压止血带衬垫材料,观察比较两组的止血效果、皮肤损伤发生率以及对电动气压止血带袖带的保护情况。结果弹力绷带组患者的皮肤压痕、瘀斑、水泡等皮肤损伤发生率低于棉纸组,差异有统计学意义(P<0.05);两组止血效果比较差异无统计学意义;弹力绷带组的袖带污染发生率(4%)明显少于棉纸组(16%),差异有统计学意义(P<0.05)。结论弹力绷带作为止血带衬垫材料止血效果明显,而且能有效降低患者受压处皮肤的损伤率,同时减少了止血带袖带的污染,有利于袖带的清洁消毒。 相似文献

BackgroundIn a multi-center extension study, children 2–10 years of age, initially vaccinated with one or two doses (2–5 year-olds) or one dose (6–10 year-olds) of quadrivalent meningococcal CRM197-conjugate vaccine (MenACWY-CRM), were assessed five years later for antibody persistence and booster response using serum bactericidal assay with human complement (hSBA).MethodsChildren 7–10 and 11–15 years of age, who received MenACWY-CRM in the original study, and age-matched vaccine-naïve children, were enrolled in this extension study. After an initial blood draw, children received one dose of MenACWY-CRM as booster or primary dose, with a second blood draw 28 days later.ResultshSBA titers decreased five years after primary vaccination, but were higher than in non-vaccinated controls against serogroups C, W and Y, with substantial proportions having titers ≥8: 7–22% for A, 32–57% for C, 74–83% for W, and 48–54% for Y. Previously-vaccinated children demonstrated booster responses to revaccination against all four serogroups. Responses to primary vaccination in vaccine-naïve controls were lower and similar to primary responses observed in the original study. All vaccinations were generally well tolerated, with no safety concern raised.ConclusionsApproximately half the children vaccinated as 2–10 year-olds maintained protective antibodies against serogroups C, W and Y five years later, but fewer did against serogroup A. Declining titers five years after vaccination and robust booster responses suggest that five years may be an appropriate interval to revaccinate children, subject to epidemiology and delivery considerations. 相似文献

海南省吸毒人群HIV感染状况调查 总被引:5,自引:0,他引:5
目的摸清海南省吸毒人群艾滋病病毒(HIV)感染的相关行为的信息,为针对这组人群开展艾滋病干预措施提供依据。方法采用筛查的方法,在规定的时间内,对全省强制戒毒所的4243名戒毒人员进行HIV检测和问卷调查。结果在4243名戒毒者中,检出35名HIV抗体阳性者,平均检出率为0.82%。35名阳性者分布在东方(6.45%)、乐东(4.29%)、儋州(3.03%)、三亚(2.30%)等6个市县;有注射毒品行为者占50.3%~82.9%。感染的主要原因是通过共用针具静脉注射毒品引起,共用针具率14.2%~24.9%。结论海南省吸毒人员HIV总体上虽处于低流行水平,但是在东方、乐东、儋州、三亚等市县存在着局部流行现象,与艾滋病相关的危险行为依然存在,必须引起相关部门的关注。 相似文献
