ABSTRACT
Objective To establish a UPLC-MS/MS method for simultaneous determination of 19 chemical drugs in Traditional Chinese Medicines and health products for treating rhinitis. Methods Separation was performed on Waters ACQU-ITY UPLC BEH-C18column(2.1 mm×100 mm,1.7 μm) with 0.1% formic acid acetonitrile solution and 0.1% formic acid aque-ous solution as the mobile phase by gradient elution.The flow rate was 0.3 mL·min-1.The column temperature was set at 35 ℃. The detection was performed by the positive ion electrospray ionization (ESI+) under multiple reactions monitoring (MRM) mode. Results The linear relationships of 19 chemical drugs were good in respective ranges with correlation coefficients higher than 0.995.The average recoveries of the low,medium,and high level were in the range of 84.9%-111.1%,and the RSDs were less than 5.2%.The limits of detection (LOD) and the limits of quantitation (LOQ) were in the range of 0.03-0.78 ng·mL-1 and 0.13-1.82 ng·mL-1,respectively. Conclusion The method is convenient,rapid,accurate,and sensitive,which can be used for the determination of chemical drugs added illegally in traditional Chinese medicines and health products for treating rhini-tis.
ABSTRACT
Objective To explorer the effect of midnight-noon ebb-flow of five elements of music therapy on anxiety and depression in type 2 diabetic patients.Methods A total of 60 type 2 diabetic patients with anxiety and depression in our hospital were divided into the experiment group and the control group according to the order of admission,with 30 patients in each group.The control group received routine nursing care and general music therapy.The experiment group received routine nursing care and midnight-noon ebb-flow of five elements of music therapy.After four weeks,the results of the two groups were compared using HAMD and HAMA scales.Result Four weeks after intervention,there was improvements in the two groups ((P＜0.01) and the anxiety and depression levels in the experiment group were significantly improved than those in the control group (P＜0.01).Conclusion The midnight-noon ebb-flow of five elements of music therapy can alleviate the levels of anxiety and depression in patients with type 2 diabetes.
