人感染 HIV-1 后一般经 7-12年进入发病期。 照现行的诊疗标准, 对于无症状且 CD+T细胞数尚未大幅度降低(例如, 仍处于 300个每微升以上)的 HIV病毒携带者, 不建议给予抗病毒疗法, 否则会使病人和社会承担诱发严重抗药性的巨大风险。 根据 近十年的临床实践,对于进入发病期特别是发病早、中期的艾滋病患者,在实施 HAART 主流疗法的同时, 同时加服中药进行辅助治疗, 已见到在改善乏力、 腹泻、 恶寒等并 发症状、 减少西药引起的毒副作用、 提高患者治疗依从性、 提高患者生存质量等方面 的效果。 中药应该能够成为艾滋病治疗的选项。
天然有机化合物 Euphorbiasteroid是本发明人发现具有抗 HIV作用的一种续随子 垸型二萜化合物,单独使用显示具有一定的抗 HIV作用。经美国国家肿瘤研究所 (NCI) 测定, 在体外对艾滋病病毒(HIV-1 ) 的复制具有较强的抑制作用, 治疗指数(半数细 胞毒浓度 /半数病毒复制抑制浓度) 为 600。
