In addition, the TCM topical preparations has the disadvantages of large particle diameter and unfavorable penetration of skin barrier.

Objective: In this study, chitosan nanocrystalline drug delivery system was used to prepare Chitosan Nanocrystalline Qinteng Huoxue Runji Ointment, and the efficacy and safety of Chitosan Nanocrystalline Qinteng Huoxue Runji Ointment in the intervention of psoriasis with blood stasis syndrome was investigated through multi-center, randomized, double-blind, self-controlled bilateral skin lesions and placebo-controlled clinical trials.

Methods: A total of 96 patients with plaque psoriasis with blood stasis syndrome of were enrolled in 4 research centers, and bilateral symmetrical rashes on limbs or trunk were selected, and randomly divided into experimental group and control group.

Results Indicators: The main efficacy indicators were targeted psoriasis area and severity index (tPASI), and the secondary efficacy indicators included: Psoriasis physician global assessment (PGA), target lesion area, numerical rating scale (NRS), TCM syndrome score, dermatology life quality index (DLQI), MOS 36 item short from health survey (SF-36)), and the morphology and number of vascular globules under dermoscopy. tPASI, PGA, target lesion area, NRS were assessed at baseline, at 2, 4, 6, 8, 10, 12 weeks of treatment, and at 16 and 20 weeks of follow-up. TCM syndrome score, DLQI, SF-36, and dermoscopy were assessed at baseline, 12 and 20 weeks. Safety assessment includes vital signs monitoring, blood routine, urine routine, liver and kidney function tests, and adverse events and adverse reactions. SPSS 20.0 was used for data analysis.
