沈阳汉族群体HLAⅠ类基因座PCR-序列特异性寡核苷酸探针分型研究

目的检测和分析沈阳汉族HLA-A、-B、-Cw位点等位基因的多态性。方法采用聚合酶链反应．寡核苷酸探针杂交分型方法对108名沈阳籍健康献血员进行HLA-A、-B、-Cw等位基因分型。结果检出等位基因HLA-A位点21个，B位点43个，Cw位点23个；所有位点的等位基因频率分布符合Hardy—Weinberg平衡。结论从基因水平分析了HLA Ⅰ类基因的群体分布特征，提供了沈阳汉族群体HLA Ⅰ类基因座更准确的基因频率。     

Identification of a new HLA-Cw*01 variant, Cw*0121, by sequence-based typing in a Chinese patient

HLA-Cw^*0121 allele was identified in a Chinese patient. It is identical to Cw^*0104 except for five nucleotides changes.     

Pustulosis palmaris et plantaris with prominent hyperkeratosis of the soles

A 50-year-old woman developed prominent hyperkeratosis on the soles and erythema of her extremities. In this instance it was clinically difficult to distinguish the palmoplantar lesions from psoriasis vulgaris. However, our case proved to be palmoplantar pustulosis (PPP) because, on histology, the extra-palmoplantar lesions showed none of the typical findings of psoriasis vulgaris, there was a history of sternoclavicular joint pain, and the lesions improved after tonsillectomy. Herein, we consider the relationship between prominent hyperkeratosis of the sole or palm in PPP and bacterial infection.
