检索并纳入1995-2016年发表的治疗糖尿病相关文献755篇，涉及中药处方755首，单味中药367味，共治疗糖尿病及其并发症的有效例数为33 330例，探讨中医药治疗糖尿病及其并发症的用药规律。采用Microsoft Excel 2010软件和Clementine 12.0软件，分析与比较各病症类型的单味中药使用频次、功效和组方配伍规律。中医药在治疗糖尿病及其并发症方面，治疗病症类型排名前4位的分别是糖尿病、糖尿病神经系统并发症、糖尿病肾病和糖尿病心血管并发症，分别占总有效病例数的31.62%、29.82%、8.87%和6.47%。进一步对治疗排名前4位的病症进行分析，发现治疗糖尿病的常用单味药为黄芪、山药、地黄、天花粉和麦冬等，常用中药类别依次为补虚药、清热药和活血化瘀药；治疗糖尿病的神经系统并发症常用单味药为黄芪、当归、川芎、丹参和桂枝等，常用中药类别依次为补虚药、活血化瘀药和清热药；治疗糖尿病肾病的常用单味药为黄芪、山药、丹参、茯苓和山茱萸等，常用中药类别依次为补虚药、活血化瘀药和利水渗湿药；治疗糖尿病心血管并发症的常用单味药为黄芪、丹参、当归、红花和川芎等，常用中药类别为活血化瘀药、补虚药和清热药。中医药治疗糖尿病、糖尿病神经系统并发症、糖尿病肾病和糖尿病心血管并发症的用药规律具有一定的相似性，均以补虚药为主，兼以活血化瘀、清热和利水渗湿药等，但具体用药侧重点不同，糖尿病和糖尿病神经系统并发症侧重补虚药，兼以活血化瘀药和清热药的使用，糖尿病肾病侧重于补虚药，兼以活血化瘀药和利水渗湿药的使用，而糖尿病心血管并发症侧重于活血化瘀药和补虚药并重，兼以清热药使用。
