韶关市农村留守儿童孤独感状况调查 总被引:1,自引:0,他引:1
目的了解广东省韶关市农村地区留守儿童孤独感现状及其影响因素。方法对韶关市某地区两所农村小学3~6年级学生中的489名留守儿童采用儿童孤独量表和自编调查表进行问卷调查。结果17.6%留守儿童存在孤独感,不同性别孤独感发生率无差异性,不同年龄及不同年级间孤独感发生率差异均有极显著性(P〈0.01);随年级增加,孤独感发生率呈下降趋势(X^2趋势=5.970,P〈0.05)。留守儿童孤独感与健康状况、学习成绩、学习困难程度、父母教育方式、父母间关系和老师教育方式等因素显著相关(P〈0.01~0.05)。结论农村地区留守儿童中存在一定程度的孤独感问题,老师和家长应以正确的态度和方法对待留守儿童,以减少其孤独感的发生。 相似文献

目的对比观察产科新生儿不同部位经皮胆红素(TCB)报警预值的可靠性。方法132例产科新生儿采取随机数字分组法分为正常产组和剖宫产组各66例,新生儿均于产后第4天同一时间点应用KJ8000经皮测黄仪分别测量额、胸、腹、额胸、额胸腹TCB值,TCB〉12.9mg/dl者,取得亲属同意抽取静脉血检测血清胆红素(SB),对比分析不同部位TCB及其与sB值的差异。结果两组分别有17例或21例达到TCB报警预值。两组TCB或sB相同方法及相同部位比较,差异无统计学意义(P〉0.05);两组TCB不同部位对比,额部值最低、胸部值最高,且与其他部位同组对比差异均有统计学意义(P〈0.01);两组sB值对比差异无统计学意义(t=1.53,P〉0.05),与不同部位TCB对比均以胸部数值差异无统计学意义(P〉0.05),而与其他部位TCB两组差异均有统计学意义(P〈0.01)。结论正常产与剖宫产新生儿术后sB对比差异无意义;TCB动态监测以胸部结果更接近SB。 相似文献

The adequacy of implementation of present proteinuria diagnostic thresholds under examination of pregnant women was examined. The analysis was applied to all urine samples of pregnant women from December 2009 to March 20010. The amount of protein in urine was concurrently evaluated by turbidimetric analysis with sulfosalicylic acid, colorimetric analysis with pyrogallol red, "dry chemistry" technology (the diagnostic strips). It is established that the mentioned techniques of analysis of protein in urine provide independent results. The results of colorimetric analysis are characterized by better precision and adequacy. However, in case of pregnant women the diagnostic threshold of protein concentration should be shifted from 0.120 to 0.150 g/l. 相似文献

目的 探讨超声在评价放疗对颈动脉溃疡斑块形成的影响的价值。方法 回顾性收集经病理学证实为头颈部肿瘤、放疗前后的颈动脉超声资料以及其他基线资料完整的患者93例,比较放疗前后放疗侧颈动脉和非放疗侧颈动脉粥样硬化斑块和溃疡斑块的总数量、平均内膜-中膜厚度、最大斑块面积、最大溃疡斑块的面积、最大溃疡口的面积。结果 放疗前后颈动脉超声检查的平均间隔时间为(6.1±1.9)年;放疗前放疗侧斑块总数量、平均内膜-中膜厚度、最大斑块面积、溃疡斑块的总数量、最大溃疡斑块的面积、最大溃疡口的面积与非放疗侧比较差异均无统计学意义(P均>0.05);放疗后放疗侧斑块总数量、平均内膜-中膜厚度、最大斑块面积、溃疡斑块的总数量、最大溃疡斑块的面积、最大溃疡口的面积均较非放疗侧加重,差异有统计学意义(P均<0.05)。结论 放疗可导致头颈部肿瘤患者颈动脉粥样硬化斑块的形成和进展,且斑块具有易损性特点。 相似文献

Dissection of living brain tissue for in vitro experiments requires the use of a rapid euthanasia method. However, the method must not subject animals to unnecessary pain and must be aesthetically acceptable to experimenters. The purposes of the current study were to assess the aesthetics of 6 euthanasia methods, measure the procedure duration, and evaluate brain for pathology after each procedure. We digitally recorded euthanasia of isoflurane-anesthetized rats by 6 physical methods: anesthetic overdose, cardiac exsanguination, decapitation, closed intrathoracic transection of the great vessels and heart, thoracic percussion, and thoracotomy with rupture of great vessels. Volunteer researchers and animal caretakers watched the video and completed an associated questionnaire. Anesthetic overdose and cardiac exsanguinations were rated most aesthetically pleasing, although these procedures took the longest to complete. In contrast, decapitation and thoracic percussion were the least aesthetically pleasing, but these methods were the quickest. No demographic factor was identified that could predict whether a given euthanasia procedure would be favored for aesthetic reasons, and participants provided a wide variety of rationales for the aesthetic ratings they assigned. Although all of these euthanasia methods meet the criteria of approved methods of euthanasia of anesthetized rats as defined by the AVMA, aesthetic features and the scientific need for rapid euthanasia are both considerations in selecting a method. 相似文献
