Objective To observe the clinical effect of Jinchuang Ointment (JO) for treatment of refractory pressure ulcers. Methods Totally 306 patients with phase II , IIl, IV refractory pressure ul- cers were randomly assigned to the traditional Chinese herbal medicine ointment group, the JO group, the MepilexAg group,102 cases in each group. Each ulcer was scored using pressure ulcer scale for healing (PUSH) designed by National Pressure Ulcer Advisory Panel (NPUAP) before treatment, at day 7, 14, and 21 after treatment, respectively. The healing rate of pressure ulcer was observed at day 21. Results There was significant difference in PUSH score of the 3 groups between before treatment and at day 7/14)21 after treatment (P0. 01). PUSH score was better in the JC group, as compared with that in the other two groups (P0. 05) at day 14 and 21 after treatment. There was no significant difference in PUSH score between the traditional Chinese herbal medicine ointment group and the MepilexAg group (P0. 05). Conclusions JO had significant effect in treatment of patients with phase II , III, IV pressure ulcers. The rate of wound healing at day 14/21 was significantly higher than that of traditional Chinese herbal medicine ointment and MepilexAg.

The traditional Chinese medicine (Tripterygium wilfordiiHook.f., TWH) has been clinically used to treat primary and secondary renal diseases and proteinuria for nearly 40 years. However, there is a rare literature about the effect of triptolide (the main active ingredient of TWH) on the expression of oxidative carbonyl protein (OCP) in diabetic nephropathy (DN). This study aimed to provide experimental evidence for triptolide treatment on DN through its effect on the expression of OCP, in order to investigate the effects of triptolide on the expression of OCP in rats with DN. Sixty SD rats were randomly divided into five groups: control group, high-dose triptolide (Th) group, low-dose triptolide (Tl) group, DN model group, and positive control (benazepril) group. The DN model was established using streptozotocin. Urinary protein excretion, fasting blood glucose (FBG), superoxide dismutase (SOD) in renal homogenate, malondialdehyde (MDA) in renal homogenate and renal nitrotyrosine by immunohistochemistry, and the expression of OCP by oxyblotimmune blotting were detected. In the DN model group, rat urinary protein excretion and renal MDA were significantly increased, while renal SOD significantly decreased and nitrotyrosine expression was obviously upregulated in the kidney. After triptolide treatment, 24-h urinary protein excretion (61.96±19.00 vs. 18.32±4.78 mg/day, P
