ABSTRACT
Objective:To investigate the efficacy of ticagrelor combined with atorvastatin in the treatment of unstable angina pectoris and its effects on cardiac function, brain natriuretic peptide (BNP) level, lipoprotein-associated phospholipase A2 (Lp-PLA2) activity, and glycosylated hemoglobin (HbAlc) level in patients with unstable angina pectoris.Methods:A total of 200 patients with unstable angina pectoris who received treatment in the Sahzu International Medical Center from January 2017 to January 2019 were included in this study. These patients were randomly assigned to receive either clopidogrel combined with atorvastatin (control group, n = 100) or ticagrelor combined with atorvastatin (observation group, n = 100) for 1 month. The clinical efficacy,BNP level, Lp-PLA2 activity, HbAlc level, clinical symptom, cardiac function, and adverse reactions were compared between control and observation groups. Results:Effective rate was significantly higher in the observation group than in the control group [95% (95/100) vs. 75% (75/100), χ2 = 15.69, P < 0.001]. After treatment, BNP level and Lp-PLA2 activity in the observation group were (101.21 ± 40.13) ng/L and (105.56 ± 12.56) pg/L, respectively, which were significantly lower than those in the control group [(151.57 ± 37.29) ng/L, (137.52 ± 16.88) pg/L, t = 9.19, 15.19, P < 0.001]. After treatment, the duration and frequency of angina pectoris in the observation group were (1.84 ± 0.49) minutes/time and (1.32 ± 0.21) times/week, respectively, which were significantly lower than those in the control group [(5.23 ± 1.72) minutes/time and (3.58 ± 0.71) times/week, t = 18.95, 30.52, both P < 0.001]. After treatment, the left ventricular end-diastolic diameter and left ventricular end-systolic diameter in the observation group were (33.28 ± 1.21) mm and (47.89 ± 5.61) mm respectively, which were significantly lower than those in the control group [(37.56 ± 2.14) mm, (53.25 ± 5.07) mm, t = 17.41, 7.09, both P < 0.001]. Left ventricular ejection fraction was significantly higher in the observation group than in the control group [(48.59 ± 5.81)% vs. (41.16 ± 5.83)%, t = 9.03, P < 0.001]. The incidence of adverse reactions was significantly higher in the observation group than in the control group [1% (1/100) vs. 12% (12/100), χ2 = 9.96, P = 0.002]. Conclusion:Ticagrelor combined with atorvastatin is highly effective for unstable angina pectoris in coronary heart disease because it greatly decreases BNP level and Lp-PLA2 activity. Therefore, the combined therapy deserves clinical promotion.
ABSTRACT
Objective To explore the application value of liquid chromotography tandem mass spectrometry (LC-MS/MS) in screening of inherited metabolic disease risk children ,and to provide a reference for the scientific prevention and control .Methods 246 cases of patients with inherited metabolic children blood samples were collected through the blood spots ,LC-MS/MS was used to examine blood samples from high risk cases of inherited metabolic who came from general hospital of Ningxia medical university . Results 30 cases were confirmed with inherited metabolic disease by the LC-MS/MS ,the positive rate was 12 .2% ,including 9 ca-ses of methylmalonic academia ,4 cases of isovaleric acidemia ,6 cases of phenylketonuria ,2 cases of propionic acidemia ,2 cases of citrullinemia ,1 cases of very long-chain acyl-CoA dehydrogenase ,1 cases of mitochondrial trifunctional protein deficiency ,1 cases of maple syrup urine disease ,3 cases of homocystinuria ,2 cases of argininesuccinic aciduria .Conclusion Liquid chromatography tan-dem mass spectrometry(L-MS/MS) technology is highly efficient and high reliability method in screening inherited metabolic dis-ease .
