七氟醚联合丙泊酚对老年患者腹腔镜胆囊切除术后早期认知功能的影响

目的:观察七氟醚联合丙泊酚对老年患者腹腔镜胆囊切除术后早期认知功能的影响。方法:将72例行腹腔镜胆囊切除术的老年患者均分为对照组和观察组。对照组患者采用靶控静脉注射模式于术中静脉持续泵入顺苯磺酸阿曲库铵0.1 mg/(kg·h)并维持肌肉松驰,静脉+吸入丙泊酚共2 mg/kg。观察组患者在对照组给药的基础上联合给予七氟醚,呼气末浓度1.0%~2.0%。两组患者均在切皮前追加枸橼酸芬太尼注射液2μg/kg,术中每小时追加枸橼酸芬太尼注射液2μg/kg;脑电双频指数(BIS)监测麻醉深度,并根据检测结果对七氟醚的浓度和丙泊酚剂量进行控制,使BIS控制在40~60。观察两组患者入室时(T0)、插管后(T1)、切皮时(T2)、关腹时(T3)、拔管时(T4)的心率(HR)、平均动脉压(MAP)、血氧饱和度(Sp O2)及术后苏醒时间,术前及术后第1、2、7天神经精神功能指标和术后认知功能障碍发生率,并记录不良反应发生情况。结果:对照组患者T2时MAP显著高于同组其他时间点;观察组患者T1时MAP显著低于同组其他时间点,且观察组显著低于对照组(P<0.05)。两组患者术后苏醒时间比较,差异无统计学意义(P>0.05)。两组患者术后第1、3天除循迹连线指标显著高于同组术前、观察组高于对照组(P<0.05)外,其他指标均显著低于同组术前,且观察组低于对照组(P<0.05)。观察组患者术后认知功能障碍发生率显著低于对照组(P<0.05)。两组患者给药期间均未见明显不良反应发生。结论:七氟醚联合丙泊酚静脉麻醉较单用丙泊酚可更有效地改善老年患者腹腔镜胆囊切除术后早期认知功能,安全性较好。     

二烯丙基二硫下调DJ-1抑制人白血病HL-60细胞增殖及诱导分化

目的研究二烯丙基二硫(DADS)通过下调DJ-1对人白血病细胞系HL-60增殖抑制及诱导分化的影响。方法通过细胞形态法观察细胞分化;Western blot及免疫细胞化学检测DADS对HL-60细胞DJ-1表达的影响;针对DJ-1mRNA序列设计合成siRNA转染人白血病细胞HL-60,Western blot检测基因干扰效果;利用MTT法及间接免疫荧光检测DADS及DJ-1沉默对HL-60细胞的生长及细胞分化的影响。结果 DADS可以诱导HL-60细胞向成熟粒细胞系样分化。DADS呈时间依赖性抑制DJ-1的表达(P<0.05),DJ-1干扰组细胞生长减慢(P<0.05),与DADS共同作用后可诱导HL-60细胞分化。检测细胞生长情况发现干扰组细胞生长减慢(P<0.05)。结论 DADS通过下调DJ-1抑制细胞增殖并诱导HL-60细胞分化;干扰DJ-1基因可以增强DADS对HL-60细胞的增殖抑制诱导分化作用。

The Effect of Age on Outcomes After Destination-Therapy Left Ventricular Assist Device Implantation: An Analysis of the IMACS Registry

BackgroundAs patients with advanced heart failure are living longer, defining the impact of left ventricular assist devices (LVADs) on outcomes in an aging population is of great importance. We describe overall survival, rates of adverse events (AEs), and post-AE survival in patients age ≥ 70 years vs age 50-69 years after destination-therapy (DT) LVAD implantation.MethodsA retrospective analysis was conducted with the use of the International Society for Heart and Lung Transplantation Mechanically Assisted Circulatory Support (IMACS) registry. All adults age ≥ 50 years with a continuous-flow DT LVAD from 2013 to 2017 were included. The primary outcome was all-cause mortality. The secondary outcomes were the incidence of and survival after gastrointestinal (GI) bleeding, infection, stroke, pump thrombosis, pump exchange, and right-side heart failure. Mortality and AEs were assessed with the use of competing risk models.ResultsAt total of 5,572 patients were included: 3,700 aged 50-69 and 1,872 aged ≥ 70. All-cause mortality by 42 months was 55.8% in patients aged ≥ 70 and 44.8% in patients aged 50-69 (P = 0.001). Patients aged ≥ 70 had a 37.8% higher risk of death after DT LVAD implantation (hazard ratio 1.378, 95% CI 1.251-1.517). Patients aged ≥ 70 had higher risk of GI bleeding but lower risk of right-side heart failure. There was no difference between age groups for risk of infection or stroke. Experiencing any AE was associated with an increased risk of death that did not vary with age.ConclusionsPatients aged ≥ 70 years have reduced survival after DT LVAD, in part because of increased GI bleeding, while the incidence of other AEs is similar to that of patients aged 50-69 years. Careful patient selection beyond age alone may allow for optimal outcomes after DT LVAD implantation.     

上海市徐汇区和长宁区老年2型糖尿病患者结核分枝杆菌潜伏感染筛查情况及影响因素分析

目的: 分析上海市老年2型糖尿病患者结核分枝杆菌潜伏感染(latent tuberculosis infection,LTBI)筛查情况及其影响因素。方法: 顺序纳入2019年9—12月在上海市徐汇区和长宁区参加公共卫生服务项目体格检查且符合入组标准的60岁及以上老年2型糖尿病患者,共计885例(长宁区430例,徐汇区455例),采用γ-干扰素释放试验检测其LTBI状况。采用调查问卷收集研究对象社会人口学信息、行为生活方式、既往糖尿病和其他慢性病病史及肺结核患者接触史,以及体格检查情况等信息。采用非条件二分类logistic回归分析的方法分析老年糖尿病患者发生LTBI的影响因素。结果: 885例研究对象检出LTBI阳性者130例,阳性率为14.7%;其中,长宁区研究对象LTBI阳性率(17.4%,75/430)高于徐汇区研究对象(12.1%,55/455),差异有统计学意义(χ²=5.057,P=0.025);吸烟者LTBI阳性率(22.5%,20/89)明显高于不吸烟者(13.8%,110/796),差异有统计学意义(χ²=4.783,P=0.039)。logistic回归分析显示,吸烟是老年糖尿病患者发生LTBI的危险因素[OR(95%CI)=1.891(1.031~3.468)]。结论: 上海市老年2型糖尿病患者LTBI阳性率处于较低水平,可对检测阳性患者采取增加随访频次及加强健康教育等措施,并对有吸烟史的老年糖尿病患者开展LTBI筛查。
