目的 探讨长期吸烟史对高危脑卒中患者口服阿司匹林二级预防效果的影响。方法 将2012年8月—2014年8月医院口服阿司匹林二级预防的高危脑卒中患者115例作为研究对象,根据有无吸烟史分为无吸烟史组(34例)和吸烟史组(81例),其中36例吸烟时间≥20 a(长期吸烟史组)、45例吸烟时间1～19 a(短期吸烟史组)。随访12个月,测定血小板颗粒膜蛋白(GMP-140)、D-二聚体(D-D)、纤维蛋白原(FIB)、组织型纤溶酶原激活物(t-PA)、血小板膜糖蛋白CD61、CD62p,记录1年阿司匹林抵抗和临床终点事件发生率。结果 长期吸烟史组治疗前后GMP-140、D-D、FIB、CD61、CD62p高于短期吸烟史组和无吸烟史组,t-PA低于短期吸烟史组和无吸烟史组,且短期吸烟史组和无吸烟史组组间比较,差异有统计学意义(P＜0.05);长期吸烟组阿司匹林抵抗发生率和临床终点事件发生率分别为33.33%、30.56%,高于无吸烟史组的8.82%、8.82%,差异有统计学意义(P＜0.05),其余组组间比较差异无统计学意义(P＞0.05)。结论 长期吸烟史会使脑卒中患者存在血栓前状态,增加阿司匹林抵抗和临床终点事件的发生几率。

Objective To explore effects of long-term smoking on secondary prevention for oral aspirin in high-risk stroke patients. Methods A total of 115 high-risk stroke patients who orally took aspirin for secondary prevention in our hospital from August 2012 to August 2014 were selected as the study subjects. According to smoking or not, they were divided into non smoking history group (34 cases) and smoking history group (81 cases). Among them, 36 cases whose smoking time was ≥ 20 years were included in the long-term smoking history group, and 45 cases whose smoking time was 1 to 19 years were included in the short-term smoking history group. The patients were followed up for 12 months. The platelet granule membrane protein (GMP-140), D-dimer (D-D), fibrinogen (FIB), tissue plasminogen activator (t-PA), platelet membrane glycoprotein CD61 and CD62p were determined. The incidence rates of 1-year aspirin resistance and clinical outcome events in the three groups were recorded. Results Before and after treatment, GMP-140, D-D, FIB, CD61 and CD62p in long-term smoking history group were higher than those in short-term smoking history group and non smoking history group while T-PA was lower, and there were significant differences between short-term smoking history group and non smoking history group (P<0.05). The incidence rates of aspirin resistance and clinical outcome events in long-term smoking history group (33.33%, 30.56%) were higher than those in non smoking history group (8.82%, 8.82%)(P<0.05), but there was no significant difference among other groups (P>0.05). Conclusion Long-term smoking history will cause prethrombotic state in stroke patients and increase the incidence rates of aspirin resistance and clinical outcome events.

目的 探讨妇科门诊宫颈癌高危人群采取阴道镜检查后配合宫颈细胞学检查对宫颈癌筛查价值。方法 选取2016年2月—2017年4月我院妇科门诊就诊合并宫颈癌高危患者387例为研究对象,所有患者均行阴道镜检查和宫颈细胞学检查,以最终病理检查为诊断“金标准”,探究阴道镜、宫颈细胞学检查在宫颈癌中筛查灵敏度、特异度及阳性符合率。结果 387例纳入研究宫颈癌高危患者,经病理诊断后明确诊断为宫颈癌51例,占13.18%。细胞学检查在宫颈癌中筛查灵敏度为72.55%,特异度为90.48%,阳性符合率为88.11%。阴道镜检查在宫颈癌中筛查灵敏度为50.98%,特异度为94.64%,阳性符合率为88.89%。宫颈癌筛查中,细胞学检查灵敏度高于阴道镜检查,特异度低于阴道镜检查(P＜0.05),两者检查阳性符合率比较差异无统计学意义(P＞0.05)。结论 妇科门诊宫颈癌高危患者宫颈筛查中,阴道镜筛查具有较高特异度,细胞学检查具有较高灵敏度,联合检查能提高筛查价值。

目的 评价围术期目标导向液体治疗用于老年高危患者的优越性。方法 50例行择期全髋关节置换术的老年患者,随机分成传统液体治疗组(C组)和目标导向治疗组(GDT组),每组25例。C组以MAP和CVP为指导进行围术期液体管理,GDT组以每搏量(SV)和氧供指数(DO₂I)最大化进行围术期液体管理。观察和比较两组患者围术期液体出入量、MAP、HR、SV和CI等参数。结果 GDT组总输液量、晶体液和胶体液的输注总量均高于C组(P＜0.05);GDT组各时点MAP、HR、SV和CI高于C组(P＜0.05),与基础值比较,GDT组无变化,而C组在麻醉后和应用骨水泥后,MAP、HR、SV和CI一过性下降(P＜0.05)。结论 与传统围术期液体管理方案相比,以SV和DO₂I最大化为目标的GDT方案用于高危病人全髋置换手术,能使心脏前负荷处于更理想的充盈状态,血流动力学更稳定,并能有效预防骨水泥引起的循环抑制作用。

Objective To evaluate the priority of goal-directed fluid therapy(GDT) in high risk elderly patients. Methods Fifty elderly patients undergoing total hip replacement were randomly divided into traditional fluid therapy group(group C) and goal-directed fluid therapy group(group GDT). Group C received perioperative fluid management based on MAP and CVP, while Group GDT received goal-directed fluid therapy based on SV and DO₂I optimization. MAP, HR, SV, and CI were recorded at different time points; the intraoperative blood loss, fluid volume, and urine volume were also recorded. Results The total fluid volume, colloid volume and crystal volume of group GDT were much more than group C(P＜0.05); the intraoperative MAP, HR, SV, and CI in group GDT were much higher than group C(P＜0.05); compared withbaseline of MAP, HR, SV, and CI, there were no obvious change in group GDT, while there were significant decline in group C, especially after anesthesia and implantation of bone cements(P＜0.05). Conclusion Compared with traditional fluid management strategy, SV and DO₂I optimization based goal-directed fluid therapy has a significant priority in high risk elderly patients undergoing total hip replacement.It can maintain better preload and provide more stable hemodynamic status, and prevent cardiac side effect induced by implantation of bone cements
