目的:迄今为止,吸烟对脑血流量的影响机制尚不清楚。本研究旨在通过使用磁共振血管成像(MRA)定量评估吸烟对脑血管血流动力学的动态影响。方法:本研究纳入15名45岁以下且吸烟史超过3年的健康男性吸烟者。使用相位对比MRA测量11个脑血管段的血流率(CFR,mL/s)和流速(FV,cm/s),用于评估血管血流动力学变化。并对吸烟前后血管内血流量和流速的数据进行配对t检验。随后从15名志愿者中随机选取3名作为对照组,实验过程中不吸烟,MRA检查序列及测量方法同实验组。结果:吸烟后,远端脑血管(大脑前动脉、大脑中动脉和大脑后动脉)总的脑血流率从847mL/s降低至785mL/s,降幅为7.3%,差异有统计学意义(P=0.024);且前循环(大脑前动脉和大脑中动脉)的血流量变化较后循环(大脑后动脉)更为显著。然而,所有远端脑血管内血液流速均无明显变化,收缩期峰值速度和平均速度分别下降7.4%和4.3%,颈内动脉的搏动指数下降10.9%。此外,吸烟后脑血管远端分支的横截面面积减少,尤以大脑中动脉为著,从9.9mm 2减低至9.3mm 2,差异有统计学意义(P=0.016)。结论:吸烟后,健康青年男性吸烟者的脑血流率降低显著,尤以前循环为著。综合考虑流速和横截面面积的动态演变,可得出结论为吸烟后脑血管阻抗增加,特别是颅内远端脑血管主干。

良性的无神经症状的骨质疏松患者的压缩性骨折本质上是稳定的骨折,常采用非手术治疗。鉴于其治疗方式通常包括佩戴矫形器,本研究比较了刚性支撑、软支撑矫形器和无支撑的治疗效果。60例患者的平均年龄为72.25岁,都是急性一个节段的骨质疏松性压缩性骨折,随机分组后分别佩戴软支撑、刚性支撑和无支撑的矫形器。指导患者持久穿戴,平躺时除外,共八周。主要预后判断为骨折后12周进行Oswestry功能障碍指数（ODI）评分。

AIM:To investigate the current seroprevalence of hepatitis A virus(HAV) antibodies in patients with chronic viral liver disease in *** also tried to identify the factors affecting the prevalence of HAV antibodies. METHODS:We performed an analysis of the clinical records of 986 patients(mean age:49±9 years,714 males/272 females) with chronic hepatitis B virus(HBV) or hepatitis C virus(HCV) infection who had undergone HAV antibody testing between January 2008 and December ***:The overall prevalence of IgG anti-HAV was 86.61%(854/986) in patients with chronic liver disease and was 88.13%(869/986) in age-and gendermatched patients from the Center for Health *** anti-HAV prevalence was 80.04%(405/506) in patients with chronic hepatitis B,86.96%(20/23) in patients with chronic hepatitis C,93.78%(422/450) in patients with HBV related liver cirrhosis,and 100%(7/7) in patients with HCV related liver *** anti-HAV prevalence according to the decade of age was as follows:20s(6.67%) ,30s(50.86%) ,40s(92.29%) ,50s(97.77%) ,and 60s(100%) .The antiHAV prevalence was significantly higher in patients older than 40 years compared with that in patients younger than 40 years of *** analysis showed that age≥40 years,female gender and metropolitan cities as the place of residence were independent risk factors for IgG anti-HAV seropositivity. CONCLUSION:Most Korean patients with chronic liver disease and who are above 40 years of age have already been exposed to hepatitis A virus.

Background Delayed facial palsy ( DFP) after microvascular decompression ( MVD) in patients with hemifacial spasm ( HFS) is not uncommon,but the cause remains unknown. Objectives To assess whether intraoperative electromyography ( EMG) and brainstem auditory evoked potential ( BAEP) can predict DFP after MVD. Methods Between September 2009 and February 2011 we examined 86 patients,9 of whom ( 10. 4% ) developed DFP after MVD on the same side. All patients underwent MVD and were followed - up for a median period of 13 months ( range 6-22) . We retrospectively examined intraoperative facial EMG and BAEP findings using our MVD patients' registry. We excluded secondary HFS and immediate postoperative facial palsy after MVD in this study. We assessed the prevalence and clinical characteristics of DFP and compared EMG and BAEP findings between DFP and non-DFP groups. Results: All pa- tients recovered completely,with a mean time to recovery of 37. 8 days ( range 22-57) . There were no significant differences between DFP and non - DFP patients in terms of the amplitude and latency of intraoperative EMG and BAEP. Conclusion The usefulness of intraoperative facial EMG and BAEP is limited and cannot predict DFP after MVD for HFS. We speculate that DFP after MVD is not associated with permanent nerve damage according to the EMG findings.
