RESUMO
Objective The article aimed to identify health-related quality of life(HRQOL) themes of patients with Crohn's disease(CD) and establish a HRQOL model by a meta synthesis of qualitative studies on CD patients′ HRQOL. Methods A retrieval of HRQOL-related qualitative studies on CD patients was conducted in databases including DirectPsycINFO, VIP, etc and the results were integrated by integrating method. Results A total of 8 researches were included to refine 44 results which were integrated into 15 themes. The themes were further grouped into 6 HRQOL domains: physical function, psychological function, social function, study and work skills, sexual function, perception of health and well-being. Conclusion HRQOL themes of CD have been identified and a preliminary HRQOL concept model has been established, which will provide a reference for the development of HRQOL evaluation tools in CD patients.
RESUMO
A high-performance liquid chromatographic (HPLC) method with ultraviolet (UV) detector had been developed for simultaneous quantification of danshensu, protocatechuic aldehyde, caffeic acid, salvianolic acid D, rosmarinic acid, salvianolic acid B and salvianolic acid A in Danshen injection. According to the UV spectra of these components, three detection wavelengths have been selected as follows: 280 nm for danshensu and protocatechuic aldehyde, 326 nm for caffeic acid, salvianolic acid D and rosmarinic acid, 286 nm for salvianolic acid B and salvianolic acid A. The limit of detection (LOD) was improved to be in the range of 0.008-0.160 microg/ml. Moreover, excellent linear behavior over the investigated concentration range was observed, with R>0.999 for all the analytes.
