简介:摘要目的分析输血前检测8项感染性指标的临床意义。方法选取2015年1月-2015年12月300例医院收诊输血患者的临床资料进行回顾性分析,所有患者在输血前行乙肝病毒5项(HBsAg、HBsAb、HBeAg、HBeAb、HBcAb)、丙肝病毒抗体(HCV)、人免疫缺陷病毒抗体(HIV)以及苍白密螺旋体(TP)等8项感染性指标。结果300例患者中,HBsAg阳性者18例(6.0%)、HBsAb阳性者108例(36.0%)、HBeAg阳性者9例(3.0%)、HBeAb阳性者72例(24.0%)、HBcAb阳性者150例(50.0%)、HCV阳性者9例3.0%、HIV阳性者1例(0.3%)、TP阳性者3例(1.0%)。男性患者在HBsAg、HBeAb、HBcAb方面的阳性率与女性患者相比,差异有统计学意义(P<0.05),其他指标方面的差异无统计学意义。年龄>60岁患者仅在HIV、HBsAb方面与年龄≤60岁患者的差异无统计学意义,其余指标均有统计学意义(P<0.05)。结论输血前感染性指标检测能够发现患者潜在感染疾病,进而做出防治措施,避免出现交叉感染的现象,能够降低医疗纠纷发生率。

简介:摘要目的为了更全面了解并掌握云南省龙陵县儿童碘营养状况,为碘缺乏病以及相关措施与政策的实施提供有效依据。方法抽取龙陵县5个乡(镇)村小学200名8-10周岁儿童的尿样,依据WS/T107-2006方法,检测样本,并采用触诊法或B超法检查儿童甲状腺肿大情况。结果2015年龙陵县8-10岁学龄儿童尿碘中位数为264.74ug/L,大于300ug/L的为75份,占37.5%,小于100ug/L的为22份,占11%;不同年龄及不同性别之间尿碘值差异无统计学意义,P>0.05。结论龙陵县8-10岁学龄儿童的尿碘状况总体良好,已达到消除碘缺乏病标准,但有部分儿童碘营养水平偏高,有补碘过量的分险。
简介:摘要目的分析探讨慢性肾炎应用来氟米特联合糖皮质激素治疗,对患者尿蛋白、血肌酐及尿素氮水平等相关指标的影响。方法选取2010年1月-2016年10月期间我院收治的60例慢性肾炎患者进行研究,并随机分为对照组(30例)和观察组(30例),分别采取常规药物治疗以及来氟米特联合糖皮质激素的治疗方式进行治疗,观察并对比分析两组患者的治疗效果以及治疗前后的尿蛋白、尿素氮及血肌酐等指标。结果两组患者治疗前尿蛋白、尿素氮及血肌酐等指标水平无明显差异性(P>0.05);治疗后两组患者各指标均有所改善,但观察组明显较优,差异具有统计学意义(P<0.05)。结论应用来氟米特联合糖皮质激素的治疗方式,能有效降低慢性肾炎患者的血肌酐、尿蛋白及尿素氮水平,治疗效果显著。
