ABSTRACT
OBJECTIVE To explore the effects of intensive pharmaceutical intervention led by clinical pharmacists on hypertension patients with medium and high risk of ischemic stroke. METHODS The hypertension outpatients with medium and high risk of ischemic stroke， who were assessed by the modified Framingham stroke scale in Zhengzhou People’s Hospital from Oct. 2019 to Apr. 2020， were randomly divided into control group and intervention group， with 200 cases in each group. Patients in the control group received conventional treatment without pharmaceutical intervention； on the basis of conventional treatment， patients in the intervention group received 12-month intensive pharmaceutical intervention （grading management of compliance+ regular follow-up， involving medication education and guidance， blood glucose， blood pressure， blood lipid management and healthy life guidance） provided by clinical pharmacists. The blood glucose indexes， blood lipid indexes， blood pressure compliance rate， medication compliance， 10-year stroke risk and stroke incidence were compared between two groups at baseline and 12 months after enrollment. RESULTS After 12 months of enrollment， the level of low-density lipoprotein cholesterol （LDL-C） in intervention group was significantly lower than that in the same group at baseline， and the levels of fasting blood glucose， glycosylated hemoglobin， total cholesterol and LDL-C in intervention group were significantly lower than those in control group at the same time points （P＜0.05 or P＜0.01）. The compliance rate of blood pressure and medication compliance in intervention group were significantly higher or better than those in control group （P＜0.01）. There were 12 and 15 patients in control group and intervention group turned into low-risk ones respectively， and the proportion of high-risk patients in intervention group was significantly lower than that in control group（P＜0.01）， while the proportion of medium-risk patients was significantly higher than that in control group（P＜0.05）； the incidence of stroke in intervention group was significantly lower than that in control group （1.0% vs. 4.5%， P＜0.05）. CONCLUSIONS The pharmaceutical intensive intervention led by clinical pharmacists can reduce blood glucose and blood lipid levels of hypertensive outpatients， improve their blood pressure compliance rate and medication compliance， and help reduce the risk of stroke.
ABSTRACT
Objective To improve the quality control of Dilong Shenmai oral liquid. Methods TLC was used for the qualitative identification of Astragali Radix, Ophiopogonis Radix and Schisandrae Chinensis Fructus in Dilong Shenmai oral liquid. HPLC was used to determine the contents of schisandrin and ethylparaben in the preparation. Wondasil C18 column (250 mm×4.6 mm, 5 μm) was used with acetonitrile-water as the mobile phase at the flow rate of 1.0 ml/min for gradient elution. The detection wavelength was set at 254 nm, and column temperature was 30 ℃. Results TLC spots were clear and well-separated without negative interference. The linear ranges of schisandrin and ethylparaben were 5.81−58.06 μg/ml (r=0.999 9) and 25.29−252.94 μg/ml (r=0.999 9). The average recoveries were 99.35% (RSD=1.02%) and 99.72% (RSD=0.76%). Conclusion This method is simple, quick and accurate. It can be used for effective quality control of Dilong Shenmai oral liquid.
ABSTRACT
OBJECTIVE:To establish a method for simultaneous determination of (R,S)-goitrin and chlorogenic acid in Banchai oral liquid.METHODS:The dual-wavelength HPLC method was adopted.The determination was performed on Wondasil C18 column with mobile phase consisted of acetonitrile-0.1％ phosphoric acid (11∶89,V/V) at the flow rate of 1.0 mL/min.The detection wavelengths were 245 nm for (R,S)-goitrin and 327 nm for chlomgenic acid.The column temperature was 30 ℃,and injection volume was 10 μL.RESULTS:The linear ranges were 4.05-40.51 μg/mL for (R,S)-goitrin (r=0.999 9),29.41-294.05 μg/mL for chlorogenic acid (r=0.999 9).The limits of quantification were 3.32,2.45 ng,limits of detection were 1.00,0.74 ng.RSDs of precision,stability and reproducibility tests were lower than 1.0％;the recoveries were 98.46％-101.06％ (RSD=0.98％,n=9) and 98.18％-100.78％ (RSD=0.86％,n=9).CONCLUSIONS:The method is simple,accurate,sensitive and reproducible,and can be used for simultaneous determination of (R,S)-goitrin and chlorogenic acid in Banchai oral liquid.
