高频超声在寻常型银屑病中医辨证分型中的应用

Application of high-frequency ultrasound in TCM syndrome differentiation of vulgaris psoriasis

目的:运用高频超声技术研究寻常型银屑病患者皮损厚度与中医辨证分型的关系,探求无创、有效的评价银屑病中医辨证分型的客观依据。方法:将87例寻常型银屑病患者按中医辨证分为血热证组、血燥证组、血瘀证组,应用高频超声检测各组患者靶皮损及周围正常皮肤的表皮及真皮厚度。结果:银屑病患者皮损区表皮和真皮均较周围正常皮肤增厚,真皮增厚尤为明显;血瘀证组的皮损区真皮厚度指数大于血热证组及血燥证组, 差别有统计学意义(P<0.05)。结论: 血瘀证患者的皮损区皮肤增厚程度较血热证及血燥证明显。应用高频超声检测银屑病皮损厚度可能成为血瘀证银屑病患者与非血瘀证银屑病患者中医辨证分型的客观指标。

Objective： To study the correlation between the thickness of psoriasis skin and TCM syndromes, and to find an uninjurious and effective way to determine TCM syndromes by high-frequency ultrasound. Methods： Eighty-seven patients were divided into three groups： blood-heat syndrome group, blood-dryness syndrome group and blood-stasis syndrome group. The patients＇ epidermal and dermal thickness of targeted psoriasis skin and surrounding normal area was measured by high-frequency ultrasonic apparatus. Results： The thickness of epidermal and dermal of psoriasis skin was thicker than that of surrounding skin, and it was more obviouse of derma. The dermal thickness indexes of blood-stasis patients was the biggest in the three groups （ P〈0.05 ） . Conclusion： Blood-stasis syndrome patient＇ skin was thicker as compared to that of the other two groups. Psoriasis skin＇s thickness may be the evidence to discriminate blood-stasis syndrome and no-blood-stasis syndrome.
