Abstract: AIM:To observe the effects of Buqiyangyinlianhan(BQYYLH) decoction on patients with night sweat. METHODS:A total of 73 patients in our hospital in 2007 were randomly divided into two groups:BQYYLH decoction-treated group (n =37) and Yupingfeng (YPF) granule-treated group (n = 36). After the confirmation of differentiation of symptoms and signs for classification of syndrome of the slected patients, two weeks of treatment above mentioned were performed to observe the changes in clinical symptoms such as sweating volume, sample tests in blood, urine and stool, and liver and renal functions. At the same time, side effects of the drugs were also recorded. The responding standard is the improvement of sweating. RESULTS:Compared with YPF granuletreated group, BQYYLH decoction significantly improved night sweating (P <0. 01), and only the therapeutic effects on patients with insufficiency in heartblood had no significant difference to those of YPF granule-group(P >0. 05), the therapeutic effects on the other two syndrome types were better than those of YPF granule-group(P <0. 01). Neither BQYYLH decoction nor YPF granule caused adverse effects such as changes in liver and renal functions and sample tests in blood, urine and stool. CONCLUSION:BQYYLH decoction may be a choice to treat night sweating with few side effect, its therapeutic effect was better than that of YPF granule.
