Objective To observe the effect and adverse effect of ultrashort wave combined with Etroricox-ib in treatment of periarthritis of shoulder. Methods 80 cases with periarthritis of shoulder from March 2015 to March 2016 were randomly assigned into treatment group and control group. Etroricoxib therapy was provided in control group while ultrashort wave plus Etroricoxib therapy in treatment group. VAS ,ROM and MBI were applied for the evaluation before and after the treatment. The differences of clinical cure rate ,recurrence rate and adverse reactions were observed between 2 groups. Results There were higher cure rates ,lower recurrence rates and less adverse reactions in 2 groups after the treatment. The shoulder joint pain ,rang of should motion and BI of both groups were improved with significant differences after the treatment ,but treatment group witnessed more improve-ment(P<0.05). Conclusions Ultrashort wave combined with Etroricoxib therapy can relieve shoulder pain ,and further improve the function of shoulder joint activity in the treatment of periarthritis of shoulder. It is recommended for clinical application.

Objective:To determine the content of Chikusetsu saponin Ⅳa in the roots, stems and leaves in Panacis japonici rhizoma, and explore its development value. Methods:By using High Performance Lliquid Chromatography (HPLC) method to determine the content of Chikusetsu saponin Ⅳa in the roots, stems and leave of Panacis japonici rhizoma. Inertsil ODS-sp (4.6 mm×150 mm, 5 μm) was used as the column and the acetonitrile-0.2% phosphoric acid (35:65) as the mobile phase. The flow rate was 1 ml/min with the temperature 35 ℃ under wavelength 210 nm. Results:The linear ranged from 1-10 μg of Chikusetsu saponin Ⅳa was good ( r=0.999 5). The content of Chikusetsu saponin Ⅳa in the roof, stem and leaf were 2.169%, 0.269%, 0.169%, respectively. Conclusions:The roof of Panacis japonici rhizoma contains the highest level of Chikusetsu saponin Ⅳa followed by stem and leaf. The roof part could be used as the medical part and its stem and leaf are also valuable for further development.
