RESUMO
Objective To investigate the association between β2-adrenergic receptor gene polymorphism and coronary atherosclerotic heart disease, and to provide reference for clinical disease prevention and treatment.MethodsThe clinical data of 200 patients with coronary atherosclerotic heart disease confirmed by coronary angiography were selected and included in the study group, and 200 healthy subjects without coronary atherosclerotic heart disease group.The polymorphism of β2 adrenergic receptor gene was detected and the frequency of each gene was analyzed.ResultsThe genotype frequencies of β2-adrenergic receptor gene were in accordance with Hardy-Weinberg equilibrium, the difference was not statistically significant.According to dominant genetic model, the frequency of AA+AG was 46.0% vs 58.0% lower than that of the control group, and had statistical significance, The genotype frequency of GG genotype in study group was significantly lower than that in control group 14.0% vs 26.0%, χ2=26.20, P=0.00.The frequency of GG genotype in study group was significantly higher than that in control group 54.0% vs 42.0%, χ2=5.76, P=0.01.The frequency of A gene was 38.0% compared with 44.0% in control group, χ2=1.48, P=0.22;the frequency of AA gene in study group was 30.0%, and the frequency of gene A was 38.0%, compared with 56.0% Compared with 32.0% in the control group, χ2=0.18, P=0.66.ConclusionThe A/G polymorphism of β2-adrenergic receptor gene is closely related to the clinical pathogenesis of coronary atherosclerotic heart disease, and the A allele may be a protective factor in patients with coronary atherosclerotic heart disease.
RESUMO
Objective To investigate the impact of carvedilol on plasma cytokines in patients with chronic congestive heart failure(CHF) and its efficacy analysis.Methods 72 hospitalized patients with CHF were randomly divided into observation group and control group.The two groups were given standard therapy after admission.The observation group were given addition of carvedilol with an initial dose of 3.125mg,2 times daily,gradually increasing amount until the maintenance dose of 25mg,2 times daily for 12 weeks.Results After 12 weeks of treatment,plasma TNF-α,IL-1 and IL-6 in both groups were significantly decreased than before (t =3.02,3.17,2.97,2.26,2.25,2.21,all P ＜ 0.05) and the decline in the observation group was more significant than those in the control group(t =2.32,2.35,2.29,all P ＜ 0.05);The total clinical efficiency in the observation group(94.44％) was significantly higher(77.78％)(x2 =4.18,P ＜ 0.05),and there were no significant adverse drug reactions during treatment in both groups.During 1-year follow-up after treatment,re-hospitalization rate in the observation group (61.11％) was significantly lower than that in the control group (36.11％) (x2 =4.50,P ＜ 0.05),but there was no statistically significant difference in mortality between two groups (x2 =0.26,P ＞ 0.05).Conclusion Carvedilol is a safe and effective drug for the treatment of CHF,which can lower plasma cells factor TNF-α,IL-1 and IL-6 levels,reduce patient re-hospitalization rates,and help to improve the patients' prognosis.
RESUMO
Objective To screen the plasma differential expressed proteins in patients with Crohn's disease(CD)and ulcerative colitis(UC)using surface-enhanced laser desorption ionizationtime of flight mass spectrometry,and to establish decision trees algorithms.Methods The plasma samples from 24 UC patients,25 CD patients and 25 healthy controls were analyzed with CM10 protein chip.The proteomic spectra of CD,UC and inflammatory bowel disease(IBD)were compared with controls respectively.The differential proteins that significantly altered expression levels were selected to establish decision trees algorithms of CD.UC and IBD and then blind validations were tested.Results In the range of m/z 2000-30 000,differential expressed proteins that changed at least 2-fold between CD and controls were 9.between UC and controls were 5,and between IBD and controls were 11(P＜0.05).The software automatically picked up the m/z 8208 and 8837 as decision trees algorithms for differentiating CD from controls and m/z 6985 for differentiating UC from controls as well as m/z 8208,1752,28840 and 1702 for differentiating IBD from controls.The sensitivities of decision trees algorithms for CD,UC and IBD were 96%,82%and 91%respectively,and the specificities were 100%,85%and 100%respectively.Conclusions The protein of m/z 8208 which has high sensitivity in differentiating CD from controls is worthy of further study.
