Objective To set up the quality standard of Shiwei Shujin Huoluo Powder. Methods Rhizoma Polygoni cuspidati and Cortex Cinnamomi, the main ingredients of the powder, were identified by thin layer chromatography ( TLC) , and the content of emodin in the powder was detected by high performance liquid chromatography (HPLC) . Results The spots showed by TLC were clear without interference of the negative control. HPLC results showed that linear range of emodin was 9.30 ~ 46.52 μg·mL-1, the recovery of emodin was 96.22%, and RSD was 1.76% ( N=6) . Conclusion The established method is reliable and accurate, and can be used for quality control of Shiwei Shujin Huoluo Powder.

Objective To constitute a database of chronic wounds for characterizing the patients with chronic wounds.Methods Based on the guideline of chronic wounds defined by international wound healing society,86 outpatients with chronic wounds were selected between January and October in 2013 to set up a wound database using the wound information management system.The parameters including etiology,age distribution,mean time of fracture healing and wound healing time posterior to different treatments were analyzed.Results (1) Statistical difference existed for cause distribution (P ＜0.05).Top three causes were trauma (29％),varicosity (26％) and pressure sore (19％).(2) Age distribution varied significantly among the patients with various causes of chronic wounds (P ＜ 0.05).(3) Statistical difference was observed in healing time of various types of chronic wounds (P ＜ 0.05).Diabetic wound and varicose ulcer took the longest healing time,with average 116.36 days and 88.48 days respectively.(4) Patients treated with novel dressings had shorter healing time than those managed with traditional dressings (P ＜ 0.05).Conclusions Trauma,varicosity and pressure ulcer are relatively common among the outpatients.Etiology of chronic wounds is strongly related to age and novel dressings contributed to a shortened cause of the disorder.
