摘　　要：鼻唇沟特征的异常变化是脑卒中面诊的重要依据。为了量化表征鼻唇沟特征,解决传统中医面诊时难以发现精细特征变化和信息交流困难的问题,采用了偏振参数非直观光学成像(PIMI)方法,利用非直观成像的斯托克斯S_(1)参量图谱,取得了不同年龄的健康人员和脑卒中患者病中、预后的鼻唇沟对称性量化表征数据。结果表明,健康人员鼻唇沟S_(1)图谱特征具有较好的对称性,鼻肌横部区与上唇提肌区的左右峰值均较为接近;脑卒中患者患病期鼻唇沟的S_(1)图谱明显不对称,左右峰值大多相差20以上,预后状态鼻唇沟S_(1)图谱特征更接近健康人群。该方法有望应用于脑卒中疾病的病情评估及疗效评价,促进中医数字化的发展。Abnormal changes of the nasolabial sulcus characteristics are important symptoms of stroke,usually as the basis for the stroke facial diagnosis by traditional Chinese medicine with naked-eye observation.In order to quantify the characteristics of nasolabial sulcus and to solve the problem that it is difficult to find fine feature changes and difficult to communicate information in traditional Chinese medicine facial diagnosis,the polarization parametric indirect macroscopic imaging(PIMI)method was adopted by using the Stokes S_(1)parametric image.The nasolabial sulcus characteristics of healthy people,stroke patients,and prognostic people were obtained.The results show that the nasolabial sulcus S_(1)data of healthy people has good symmetry,while it is obviously asymmetrical for the stroke patients,and the difference between the left and right peaks is more than 20.It becomes more symmetrical when the stroke patient gets better.This method is expected to be applied to the digital diagnosis of stroke diseases and the evaluation of the treatment process,promoting the development of digital Chinese medicine.
