Object To develop a method for the determination of flavonoids from the tender stem and leaf of Ampelosis grossedentata (Hand. Mazz.) W. T. Wang, and for its quality control. Methods Differential spectrophotometry was used at the wavelength of (318?1) nm, while taking dihydromyricetin as index. Results The regression equation, within the range of the control concentration in 4 576~22 88 ?g/mL, was A=29 56 C+0 005 5, with a good linearity (r=0 999 8) between the absorbance and concentration. The average recovery rate was 100 8% and RSD was 1 9% (n=5). Conclusion The method is simple, reliable and easy to operate and suitable for the quality control of Chinese medicinal materials with a better reproducibility.

Abstract: Objective To explore the efficacy and safety of photodynamic therapy (PDT) using 5-aminolevulinic acid (ALA) combined with antifungal drugs combined and comprehensive nursing intervention in the treatment of refractory kerion. Methods From January 2019 to December 2022,6 cases of refractory kerion who were treated at the Fifth People's Hospital of Hainan Province with photodynamic therapy (PDT) using 5-aminolevulinic acid (ALA) combined with antifungal drugs. A solution with 20% concentration of ALA solution was uniformly dropped on the cotton sheet, shielded from light for 3 h, and irradiated with (633±10) nm LED red light for 20-30 min. The treatment was performed once a week, with one treatment course consisting of three sessions. Prior to treatment, debridement and fire needles pre-treatment were performed. Provide timely and targeted psychological care during treatment to alleviate psychological negative disorders and health education. Follow-up examinations were conducted 6 months after the treatment to evaluate clinical efficacy, safety and patient satisfaction. Results Six children received standard ALA-PDT combined with antifungal drugs, supplemented by comprehensive nursing intervention. The cure rate of children reached 100%, and no disease relapse or atrophic scar was found. The satisfaction rate of patients and their families was 100%. Conclusions PDT combined with antifungal drugs has obvious clinical efficacy in the treatment of kerion, especially when combined with comprehensive nursing intervention. This approach can help to relieve patients' anxiety, improve treatment outcomes, enhances patient compliance, and further improve patients' satisfaction.

Objective To establish a method for the determination of tetrahydropalmatine in Fuyantai Capsule. Methods TLC Scanning was used. with n-hexane ∶chloroform ∶methanol(7 ∶3 ∶0.5)as developer,scanned by double-wavelength reflection,?S=275 nm,?R=370 nm,slit 1.2?1.2 mm,SX=3.Results The linear range of tetrahydropalmatine concentration was 0.2~1.0 ?g and r=0.9992. The average recovery was 96.7 %and RSD was 1.92 %.Conclusion This method is accurate with a good reproducibility and can be used for the quality control of Fuyantai capsule.
