简介:目的探讨特勤人员S_ⅠS_ⅡS_Ⅲ综合征特点。方法选取Ⅰ、Ⅱ、Ⅲ标准导联同时存在S波的患者心电图,分析Ⅰ、Ⅱ、Ⅲ、aVR、V1、V5导联R波与S波比值、心电轴及年龄、体型以及病史等相关参数。结果(1)S_ⅠS_ⅡS_Ⅲ综合征发生率低,仅0.9%(51/5639人);(2)51例S_ⅠS_ⅡS_Ⅲ综合征患者心电轴偏移范围宽,在-110°~+178°,平均(27.49±79.74)°,其中心电轴正常19例(37.3%)、右偏15例(29.4%)、左偏13例(25.5%)、心电轴不确定4例(7.8%);(3)S_ⅠS_ⅡS_Ⅲ综合征多见于体质量指数偏低即呈瘦长体型年轻人,体质量指数〈24.0者占58.8%(30/51);(4)疗养体检无其他异常发现。结论健康特勤人员可出现S_ⅠS_ⅡS_Ⅲ综合征,多见于瘦长体型年轻人,可能系正常心电图变异,但诊断要慎重,须经心脏超声及X射线等检查排除器质性疾病。

简介:摘要目的了解beagle犬垂体Rathke′s囊肿及甲状旁腺Küerstriner′s囊肿发生率与性别关系,为垂体及甲状旁腺毒性病理诊断提供参考。方法以460只成年beagle犬为研究对象,雌雄各半。以10%中性福尔马林固定垂体及甲状旁腺,石蜡包埋,5μm切片,HE染色,光学显微镜下观察,统计垂体Rathke′s囊肿及甲状旁腺Küerstriner′s囊肿发生率,并比较雌、雄性动物间区别。结果显示雌、雄beagle犬垂体Rathke′s囊肿发生率均为10.87%,而甲状旁腺Küerstriner′s囊肿发生率为8.70%,其雌雄犬Rathke′s囊肿及Küerstriner′s囊肿发生率差异无统计学意义。且无动物同时发生上述两种囊肿。结论成年雌雄beagle犬Rathke′s囊肿发生率均为为10.87%,甲状旁腺Küerstriner′s囊肿发生率为8.70%,且雌雄间无差异,两种囊肿发生无关联性。

简介:AbstractThroughout the past 2020, the pandemic COVID-19 has caused a big global shock, meanwhile it brought a great impact on the public health network. Trauma emergency system faced a giant challenge and how to manage trauma under the pandemic of COVID-19 was widely discussed. However, the trauma treatment of special population (geriatric patients and patients taking anticoagulant drugs) has received inadequate attention. Due to the high mortality following severe traumatic hemorrhage, hemostasis and trauma-induced coagulopathy are the important concerns in trauma treatment. Sepsis is another topic should not be ignored when we talking about trauma. COVID-19 itself is a special kind of sepsis, and it may even be called as serious systemic infection syndrome. Sepsis has been become a serious problem waiting to be solved urgently no matter in the fields of trauma, or in intensive care and infection, etc. This article reviewed the research progress in areas including trauma emergency care, trauma bleeding and coagulation, geriatric trauma and basic research of trauma within 2020.
