目的探讨161例22～45岁的子宫内膜异位症(endometriosis,EM)患者术前生活质量及工作效率的调查分析。方法采用问卷调查对术后诊断为EM年龄在22～45岁的161例患者进行定量研究,包括3个量表:SF-12、Eh.-5、WPAI。结果术前4周,EM影响身体健康导致不能完成预期工作103例(64.0%),影响情绪健康导致不能完成预期工作100例(62.1%),身体健康导致工作活动受限105例(65.2%)。疼痛影响工作69例(42.9%),步行困难67例(41.6%)。疼痛控制她们的生活66例(41.0%)。情感改变109例(67.7%),感到缺乏理解的96例(59.6%)。因健康受到的EM的影响,每周损失平均工作时间8.34h.WPAI量表显示:68%的EM患者工作效率受到影响,63.3%的患者日常活动受到干扰。关于Eh.-5量表三方面的高影响与低影响在WPAI的范围内其余指标(工作效率降低、干扰日常生活、缺勤、出勤)差异均有统计学意义(P<0.05)。结论 161例22～45岁的EM患者的症状对生活质量及工作效率有负面影响。

目的探讨急性下肢缺血(ALLI)的临床特点及治疗方法。方法回顾性分析2003年1月至2009年12月收治的ALLI患者的临床资料,根据病因将其分为急性动脉栓塞组(AE组)和急性血栓形成组(AT组),比较两组起病特点和治疗方法的异同,分析影响保肢的因素。结果共收治130例ALLI,其中AE组82例,发病率略高,合并冠心病、风湿性心脏病、房颤者多,起病情况急,症状重,就诊时间多较短;AT组48例,冬季发病率较高,男性较多,平均年龄大,多有吸烟史,就诊时间相对较迟,并且多数有肢体慢性缺血病史。AE组脉搏消失、运动障碍症状出现率较AT组为高(P值分别为0.001和0.031),其他症状发生率两组之间差别无统计学意义。死亡9例,死亡率6.9%。一期截肢13例,二期截肢8例,总体保肢率为80.70%(88/109),AT组的总体截肢率、一期截肢率和二期截肢率均高于AE组(P值分别为1.0×10-4,4.2×10-3,0.051)。吸烟史、合并糖尿病和起病时间超过24 h.影响保肢的独立危险因素。结论 ALLI应当尽早治疗,动脉切开导管取栓是治疗急性动脉栓塞的有效方法,而治疗急性血栓形成应尽可能地完善术前评估,选择合适的综合治疗方案,必要时联合置管溶栓和(或)旁路治疗。

Th. first search.for th. doubly h.avyΩ^(0)_(bc)baryon and a search.for th. E^(0)_(bc)baryon are performed using pp collision data collected via th. Lh.b experiment from 2016 to 2018 at a centre-of-mass energy of 13 TeV,corresponding to an integrated luminosity of 5.2 fb^(-1).Th. baryons are reconstructed via th.ir decays to Λ^(+)_(c)π^(-)and E^(+)_(c)π^(-).No significant excess is fbund for invariant masses between 6700 and 7300 MeV/c^(2),in a rapidity range from 2.0 to 4.5 and a transverse momentum range from 2 to 20 MeV/*** limits are set on th. ratio of th. Ω^(0)_(bc)and E^(0)_(bc)production cross-section times th. branch.ng fraction to Λ^(+)_(c)π^(-)(E^(+)_(c)π^(-))relative to th.t of th. Λ^(0)_(b)(E^(0)_(b))baryon,for different lifetime h.poth.ses,at 95%confidence *** upper limits range from 0.5 x 10^(-4)to 2.5 x 10^(-4)for th.Ω^(0)_(bc)→Λ^(+)_(c)π^(-)(E^(0)_(bc)→Λ^(+)_(c)π^(-))decay,and from 1.4x 10^(-3)to 6.9 x 10^(-3)for th.Ω^(0)_(bc)→E^(+)_(c)π^(-)(E^(0)_(bc)→E^(+)_(c)π^(-))decay,depending on th. considered mass and lifetime of th.Ω^(0)_(bc)(E^(0)_(bc))baryon.
