ABSTRACT
Objective To investigate the effect of enhanced external counterpulsation (EECP) on plasma lipoprotein phospholipase A2 (LP-PLA2) levels, vascular endothelial diastolic function in patients with unstable angina. Methods One hundred patients with unstable angina treated in our hospital were randomly divided into routine treatment group (control group n-49) and external counterpulsation group (observation group n = 51, routine treatment plus external counterpulsation therapy, 60 min/time, a total of 30 times). All selected subjects were tested for LP-PLA2 levels on the day of enrollment and on the 30 th day after treatment, and color Doppler ultrasonography was used to detect arterial blood flow-mediated vasodilation (FMD) and nitroglycerin-mediated vasodilation (NMD). Results After treatment in the observation group, LP-PLA2 decreased compared with before treatment, the difference was statistically significant (P < 0.05) , but FMD, NMD were higher than those before treatment, which had statistical difference (P < 0.05). In control group treatment afterwards, LP-PLA2, endothelium-dependent vasodilatation and non-endothelium-dependent vasodilatation did not change significantly before treatment (P> 0.05). Observations between groups showed that the increase in FMD and NMD in the observation group was significantly greater than that in the control group. P < 0.01) , plasma LP-PLA2 levels in the observation group also decreased compared with the control group (P < 0.05). Conclusion Enhanced external counterpulsation can reduce the level of LP-PLA2 in patients and improve endothelial diastolic function under the action of blood flow shear stress.
ABSTRACT
Objective To observe the effect of sequential therapy of butylphthalide injection and soft capsules for acute cerebral infarction and its influence on plasma lipoprotein phospholipase A2.Methods 120 patients with cerebral infarction were selected in the study,and they were divided into observation group (64 cases) and control group(56 cases) according to the digital table.The control group received conventional therapy plus placebo,the observation group received the sequential administration of butylphthalide injection and butylphthalide soft capsule treatment based on the conventional treatment.Before and after treatment,the plasma lipoprotein phospholipase A2 of the two groups was detected,and the National Institutes of Health Stroke Scale (NIHSS) was evaluated,compared neurological deficit improvement between the two groups and recorded adverse drug reactions of the two groups.Results There were no significant differences in NIHSS score and plasma lipoprotein phospholipase A2 level between the two groups before treatment(all P ＞ 0.05).After treatment,the NIHSS score of neurological impairment,plasma lipoprotein phospholipase A2 level in the observation group were (6.40 ± 5.22) points,(203.26 ± 29.33) ng/mL,those in the control group were (8.59 ± 6.22) points,(253.10 ± 52.99) ng/mL,the differences were statistically significant(t =-1.36,-2.089,P =0.039,0.000).The total effective rate of the observation group was 90.6％,which was higher than 67.9％ of the control group,the difference was statistically significant (x2 =9.676,P =0.002).The incidence rate of adverse reactions was similar in the two groups (P ＞ 0.05).Conclusion Sequential therapy of butylphthalide for acute cerebral infarction can improve the neurological function,decrease the level of plasma lipoprotein phospholipase A2,inhibit the inflammation of blood vessels,improve the prognosis of patients.
ABSTRACT
Objective To investigate the predictive value of plasma lipoprotein phospholipase A2 (Lp -PLA2 )and D -dimer in patients with hypertension complicated with stroke.Methods 70 hypertensive patients with stroke were selected as A group,72 patients with simple hypertension were selected as B group,and 71 healthy sub-jects were selected as C group.The light transmitting method was used to detect serum Lp -PLA2 ,and immunoturbi-dimetry was used to detect plasma D -dimer.The clinical value of the two joint detection and single detection in prediction of hypertension complicated with stroke was analyzed.Results The plasma Lp -PLA2 and D -dimer levels of A group were (471.88 ±181.49)ng/mL,(982.54 ±373.28)μg/mL,which were higher than those of B group[(195.17 ±34.74)ng/mL,(263.57 ±29.70)μg/mL]and C group[(122.94 ±46.25)ng/mL,(96.44 ± 8.49)μg/mL](F =189.7,171.1,all P =0.000).The plasma Lp -PLA2 level of A group was positively correlated with D -dimer(r =0.692,P 252g/mL forecast hypertension stroke risk sensitivity was 83.3% and specificity was 98.6%,the plasma Lp -PLA2 >176.36ng/mL forecast hypertension stroke risk sen-sitivity was 92.9% and specificity was 83.1%,and the combined prediction of hypertension stroke risk sensitivity was 87.6%,specificity was 93.5%.Conclusion The plasma levels of Lp -PLA2 and D -dimer are significantly increased in hypertensive patients with stroke,and the combined detection of the two indicators can improve the prediction of stroke risk in patients with hypertension.
