ABSTRACT
Multiple chronic conditions have become prominent health problems nowadays. There is a positive correlation between the number of chronic diseases and the risk of sleep disorders. Patients with sleep disorders will also be more difficult to control chronic diseases they have. Therefore, more attention should be paid to the sleep problems in patients with multimorbidity. This article discusses the interrelation between multimorbidity and sleep disorders from various dimensions, to provide a new vision for the prevention and treatment of sleep disorders in patients with multimorbidity.
ABSTRACT
Objective To apply accelerated solvent extraction (ASE) technique to extract Achyranthes bidentata and to explore the application of this technique in quality control of Chinese materia medica. Methods Investigation of single factor was used to optimize the conditions that affected the efficiency for ASE from A. bidentata by RP-HPLC using ecdysterone as a quantitative marker. Results The optimized conditions for ASE of A. bidentata were obtained as follows: methanol as solvent, particle size between 0.3 and 0.45 mm, temperature at 100 ℃, pressure under 10.34 MPa, 6 min duration and once extraction. Conclusion ASE technique can be used to extract A. bidentata quickly and effectively.
