对高血压性心脏病病人实施心脏彩色多普勒超声诊断意义探讨

目的:分析高血压性心脏病病人实施心脏彩色多普勒超声诊断的临床意义。方法:挑选我院收入的高血压性心脏病病人(80例)为分析目标,时间集中于2020年1月—6月。然后按照“计算机表法”实施分组,其中参照组(n=40例)实施心电图检查;分析组(n=40例)实施心脏彩色多普勒超声检查。结果:(1)检查指标。分析组的射血分数与参照组无差异(P>0.05);分析组的左房内径、左房/主动脉内径、E/A与参照组比较呈现很大差异(P<0.05)。(2)诊断结果:分析组的诊断结果(a.主动脉扩张、b.左房增大、c.左室肥厚、d.主动脉弹性减退)高于参照组(P<0.05)。结论:针对高血压性心脏病病人相关诊断的方式之中,能够获得更高的诊断结果,临床意义重大,值得借鉴。     

高空低气压对佩戴软性角膜接触镜的透明度和视觉功能的影响

目的 研究高空低气压环境对角膜接触镜、佩戴者视力和角膜的影响.方法 8名(16眼)男性近视受试者,屈光度为-0.5～-4.25 D,先后佩戴1种含水量为55%和2种含水量为38%的角膜接触镜,进行3次低压舱模拟高空环境实验,每次上升速率25 m/s,升至2500 m和5300 m各停留20 min,7000m停留20 ...     

航空生理训练成绩不同者个性特征比较

目的 了解航空生理训练参训人员的个性特征,探讨在大型航空生理训练中,影响训练成绩的心理因素,为今后指导航空生理训练提供帮助.方法 采用卡特尔16种个性因素问卷(16 personality factor questionnaire,16PF)、艾森克人格问卷简式量表中国版(Eysenck personality questionnaire-revised,short scale for Chinese,EPQ-RSC)和应付方式问卷,对参加离心机试验和低压舱试验的35名健康志愿者进行心理测查.根据离心机试验结果将受试者分为+Gz耐力7 G以上组与6 G以下组;根据低压舱试验结果将受试者分为16 km以上高空加压供氧试验完成组与未完成组.结果在离心机试验中,12名受试者完成了7 G以上抗荷耐力试验,23名未完成;16PF的聪慧性、实验性、独立性和紧张性4个因素,EPQ的内外向维度、应付方式问卷的求助、合理化和退避,两组相比差异具有统计学意义(P＜0.05或P＜0.01).低压舱试验中,24名受试者完成了16 km以上高空加压供氧试验,11名未完成;16PF的稳定性、恃强性、怀疑性、世故性,以及次级因素的适应与焦虑性和心理健康者的人格因素,EPQ的内外向维度、应付方式问卷的退避,两组相比差异有统计学意义(P＜0.05或P＜0.01).结论 参训人员的不同个性特征对航空生理训练效果有影响. Abstract： Objective To investigate the personality characteristics of trainees in aeromedical physiological training and probe into the psychological factors influencing on training performance so as to provide help for instructing future aeromedical physiological training.Methods Sixteen personality factor questionnaire(16PF), Eysenck personality questionnaire-revised, short scale for Chinese, (EPQ-RSC) and coping behaviors questionnaire were adopted for psychological test on 35 volunteers who participated in centrifuge and hypobaric chamber trainings.Subjects were both divided into above 7 G and below 6 G groups based on the G-tolerance of centrifuge training and into finished and unfinished groups based on the result of 16 km decompression training in hypobaric chamber.Results Twelve volunteers completed centrifuge training above 7 G and other 23 were not.The 16PF tested factors such as reaoning, openness to change,self-reliance and tension, and EPQ tested extraversion dimensionality, the appeal, rationalization and retreat of coping behaviors questionnaire showed significant difference between two G-tolerance groups (P＜0.05 or P＜0.01).In decompression training, 24 volunteers out of 35 accomplished the exposure above 16 km.Significances were observed between groups on emotional stability, dominance, vigilance and privateness,adaptability and anxiety of sub-factors and personality factors of psychological healthy person that tested by 16PF, and on extraversion dimensionality and retreat of coping behaviors that tested by EPQ in hypobaric chamber training (P＜0.05 or P＜0.01).Conclusions The differences of trainees' personality characteristic would influence the effect of aeromedical physiological training.Implementing the principle of combining physiological with psychological training will enable the training more scientific and effective.     

血清SF、HbA1c水平对妊娠期糖尿病孕妇围产结局的预测价值

目的 探讨血清铁蛋白(SF)、糖化血红蛋白(HbA1c)水平对妊娠期糖尿病(GDM)孕妇发生不良围产结局的预测价值。方法 选取2021年3月至2023年2月于邛崃市妇幼保健院(下称该院)行产前检查并住院分娩的GDM孕妇97例为观察组,另选取同期于该院产检的健康孕妇116例为对照组。比较两组的空腹血糖(FBG)、SF、HbA1c水平,对比分析观察组中不同围产结局孕妇的临床特征以及SF、HbA1c水平,分析GDM孕妇不良围产结局的影响因素以及血清SF、HbA1c水平预测GDM孕妇不良围产结局的价值。结果 观察组的FBG、总胆固醇(TG)、三酰甘油(TC)、低密度脂蛋白胆固醇(LDL-C)、SF、HbA1c水平均高于对照组,差异有统计学意义(P<0.05)。GDM孕妇中围产结局不良组的FBG、TG、TC、SF、HbA1c水平高于良好组,差异有统计学意义(P<0.05)。多因素Logistic回归分析显示,FBG、TG、TC、SF、HbA1c是不良围产结局的独立影响因素(P<0.05)。受试者工作特征(ROC)曲线分析结果显示,SF、HbA1c及二者联合预测曲线下面积(AUC...
