本文检测了Ｇｅｍｆｉｂｒｏｚｉｌ（ＧＦ，商品名Ｌｏｐｉｄ降脂灵是一种常用的抗动脉硬化药物，具有降低甘油三脂和升高高密度脂蛋白（ＨＤＬ）的作用）对肝细胞载脂蛋白ＡＩ的合成与分泌的作用以及可能的作用机制。在本研究中我们使用了ＥＬＩＳＡ，免疫沉淀、分子生物学技术（如ｍＲＮＡ定量、半寿期和新ｍＲＮＡ合成率等）和特异性抗体。结果发现，ＧＦ可增加载脂蛋白ＡＩ（ａｐｏＡＩ）的分泌及放射标记蛋氨酸的掺入（合成）。与对照组相比使用２００μｍ的ＧＦ可以增加ａｐｏＡＩ的分泌及合成分别达１５８％和１３０％（短期冲击）。分子生物学结果显示，使用不同浓度的ＧＦ可以增加稳定状态的ｍＲＮＡ表达（最高达２０４％）。ｍＲＮＡ的半寿期由１４．５ｈ延长到３５ｈ。而新的ｍＲＮＡ的合成率无变化。结论：ＧＦ的心脏保护作用是因为该药刺激肝脏增加ａｐｏＡＩ的合成及分泌。其机制则为延长ａｐｏＡＩｍＲＮＡ的半寿期从使ｍＲＮＡ在肝细胞内的含量增加，而与新的ｍＲＮＡ的生成无关。

Psoriasis is capable of presenting in a variety of clinical and pathologic guises including a rarely described variant variably termed hypertrophic or verrucous psoriasis. Herein, we describe the clinical and pathologic attributes of a large series of patients with this unusual variant of psoriasis and distinguish it from other entities in the differential diagnosis. The histopathologic features and clinical and demographic attributes of a series of 12 cases from 12 patients were reviewed by a single dermatopathologist (mm). The 12 patients consisted of 7 males and 5 females with an average age of 61.8 years (males 38- 93 years, females 41- 71 years). Eight of the patients were Caucasian, 3 Hispanic and 1 African- American. Six of the lesions were located on the k.ees, 4 involved the elbows, and 2 were seen on the dorsum of the hands (metacarpal- phalangeal joint). The clinical appearance of the lesions consisted of flesh- toned to white mammillated plaques (8 cases) and coalesced papules (4 cases). Each of the biopsies showed regular psoriasiform epidermal hyperplasia with acanthosis, hyperk.ratosis, and either spongiform neutrophilic or munro micro- abscesses. In addition, each showed papillomatosis with bowing of the peripheral rete ridges toward the center of the lesion (buttressing). At high power, epidermal neutrophils were seen in particular surmounting the tips of the suprapapillary plates with accompanying serum. Hypergranulosis and k.ilocytic change were not observed in any of the lesions. Human papilloma virus (HPV) immunostaining and periodic acid Schiff (PAS) special staining for fungi were negative. Verrucous psoriasis is a distinctive variant of psoriasis with overlapping clinical and pathologic features that might prompt consideration of verruca vulgaris. The presence of epidermal papillomatosis and epidermal buttressing seen in these lesions is reminiscent of the histologic features of verruca vulgaris. Similarly, the presence of coalesced papules m
