汉字识别的困难在于大量的笔道通常弯曲成一种曲线形状，并存在着一个数量庞大的字符集。要文提出一种建立在隐形Ｍａｒｋｏｖ模型（ＨＭＭ）基础上，能有效处理这类识别问题的识别模型。该模型是一种部首ＨＭＭ和连字符ＨＭＭ的互联网络。借助于ＨＭＭ的各种特征，该模型能在各种弯曲笔道上很限地工作，并具有良好的可伸缩性。为了解决同大量搜索路径引起的识别速度问题，我们利用互不相关的部首ＨＭＭ和连字符ＨＭＭ的组合。

Purpose This study was done to verify the effectiveness of acupuncture treatment on nasal obstruction caused by allergic rhinitis or rhinosinusitis, and to know the clinical effect of a novel acupuncture point named Sim-eui. Method Rhinitis patients with at least two visits to the hospital from September, 2009 to November, 2009 were randomized into either experiment or control group. The experiment group were treated with acupuncture on generally used points of rhinitis, that are GV 22, GV 23, GV 24, ST 8 (both sides), BL 2 (both sides), ST 4 (both sides), as well as Sim-eui point. The control group were treated with the general points and LI20(both sides) instead of Sim-eui point. Acupuncture needles were left in for 15 minutes for both groups. The initial and final symptom scores of SNOT-20 and a modified VAS were used to evaluate the effectiveness. The program used for statistical analysis was SPSS 15.0 for window. Wilcoxon Signed Ranks Test was done to analyze the intra-group symptom score change before and after treatment, and Mann-Whitney Test was used to compare inter-group VAS change. All the statistics were verified at a signifi cance level of 5%. Result The SNOT-20 scores before and after acupuncture treatment showed significant changes on both experiment and control groups, but there was no signifi cant difference between the two groups. All categories of the SNOT-20 showed signifi cant result, except the 'Wake up at night' and 'Lack of a good night's sleep' entries. The modifi ed VAS showed significant improvement of symptom in the experiment group compared with control group. Conclusion Acupuncture treatment using Sim-eui point seems to be helpful in improving quality of life by immediate relief of nasal obstruction.

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。
