ABSTRACT
Objective To observe the effect of intermediate care on recurrence factors and recurrence rate of elderly patients with cerebral infarction.Methods Five Hundred and ninety-eight cases of acute cerebral stroke were divided into two groups,301 cases in the experimental group and 297 cases in the control group.After the acute stage,patients in the experimental group was included into the intermediate care unit.The experimental group was given comprehensive evaluation and multidisciplinary management,including the combination of traditional Chinese and Western medicine treatment,rehabilitation training and physical therapy,medication guidance,nursing and health education.After the acute stage of the disease,the control group patients were in the general ward.The course of treatment was 2 weeks.At baseline(t0),second weeks(t1),sixth months(t2)and twelfth months(t3),the blood pressure(SBP,DBP),fasting blood-glucose(FBG),blood lipid(TC,TG,LDL),serum homocysteine(Hcy)level and the recurrence rate of cerebral infarction in all two groups were observed.Results SBP at t1,t2 and t3 was lower than that at t0 in the experimental group,and the difference was statistically significant(P＜0.05).SBP in the experimental group at t2 and t3 was lower than that in the control group.There was significant difference between the experimental group and the control group(P＜0.05).DBP at t2 and t3 was lower than that at t0 in the experimental group,and the difference was statistically significant(P＜0.05).DP in the experimental group at t2 and t3 was lower than that in the control group.There was significant difference between the experimental group and the control group(P＜0.05).FBG at t1((5.34±0.76)mmol/L),t2(5.86±1.05)mmol/L)and t3(5.62±0.89)mmol/L)were lower than that at t0((7.27±2.34)mmol/L),and the difference was statistically significant(P＜0.05).FBG in the experimental group at t2 and t3 were lower than that in the control group((6.85±0.92)mmol/L,(6.36±1.03)mmol/L).There was significant difference between two groups(P＜0.05).TC at t1((4.86±0.85)mmol/L),t2((4.21±0.76)mmol/L)and t3((3.95±0.64)mmol/L)were lower than that at t0((5.56±1.06)mmol/L),and the difference was statistically significant(P＜0.05).TC in the experimental group at t2 and t3 was lower than that in the control group((5.06±0.93)mmol/L,(4.84±0.76)mmol/L).There was significant difference between two groups(P＜0.05).TG at t3((1.48±0.26)mmol/L)was lower than that at t0((1.86±1.31)mmol/L),and the difference was statistically significant(P＜0.05).TG in the experimental group at t3 was lower than that in the control group((1.71±0.66)mmol/L).There was significant difference between two groups(P＜0.05).LDL at t1((3.76±0.92)mmol/L),t2((3.09±0.62)mmol/L)and t3((2.59±0.51)mmol/L)were lower than that at t0((4.59±1.45)mmol/L),and the difference was statistically significant(P＜0.05).LDL in the experimental group at t2and t3 was lower than that in the control group((4.09±0.75)mmol/L,(4.12±0.64)mmol/L).There was significant difference between two groups(P＜0.05).Hcy at t1((14.16±3.17)μmol/L),t2((10.37±2.59)μmol/L)and t3((10.10±1.86)μmol/L)were lower than that at t0((23.62±5.62)μmol/L),and the difference was statistically significant(P＜0.05).Hcy in the experimental group at t2and t3 was lower than that in the control group((18.52±3.64)μmol/L,(16.37±2.75)μmol/L).There was significant difference between two groups(P＜0.05).The recurrence rate of cerebral infarction within 1 years was 4.7％(14/301)and 7.1％(21/297)in the experimental group and the control group.There was a decreasing tendency,but no statistical significance(P=0.208).Conclusion The intermediate care may affect the blood pressure,FBG,blood lipids,serum Hcy levels in elderly patients with cerebral infarction,so as to reduce the recurrence rate of cerebral infarction.
ABSTRACT
Objective To observe the clinical efficacy of intermediate care in patients with after acute stroke.Methods Six hundred cases patients with after acute stroke were divided into experimental group with 301 cases and control groups with 299 cases according to the opinions of patient and family members.The experimental group was given intermediate care for 2 weeks.The control group was given the basic treatment of cerebral infarction.Activities of Daily Living (ADL) score,fall risk score and geriatric depression scale (GDS) were compared between the two groups at the time of entry,2 weeks after treatment,6 months and 12 months of follow-up.Results There were no significant differences in terms of ADL score,fall risk score and GDS between the two groups at the time of entry(P＞0.05).Compared with at the time of entry,ADL score and fall risk score were decreased of two group after 2 weeks after treatment,6 months and 12 months of follow-up(P ＜0.05),and ADL score and fall risk score of the experimental group both were lower than of the control group after 2 weeks after treatment,6 months and 12 months of follow-up(P＜0.05).Compared with at the time of entry and 2 weeks after treatment,GDS of two groups both were decreased 6 months and 12 months of follow-up (P ＜0.05),but there was no significant difference between the two groups in different time periods(P ＞0.05).Conclusion Intermediate care has a significant effect on improving the activities of daily living and reducing the risk of falls in patients with after acute stroke,and can reduce the GDS score.
ABSTRACT
Objective To determine the relationship between the rennin-angiotensin-aldosterone systems(RAAS)and left atrial structure remodeling in patients with rheumatic mitral stenosis.Methods The patients with rheumatic mitral stenosis were divided into two groups according to atrial fibrillation:sinus rhythm group(SR group,n=25)and atrial fibrillation group(AF group,n=30).17 normal subjects were selected as normal control group(NC).The plasma concentration of renin,angiotonin Ⅱ(Ang Ⅱ)and aldosterone(Ald)were measured by radioimmunoassay(RIA).Results The average value of the left atrial diameter in AF group was significantly greater than that of both SR group and NC group,increased by 16.9%[(57.71±8.07)mm vs.(48.48±5.05)mm,P＜0.01)]and 87.8%(57.71±8.07 mm vs.30.18±2.85 mm,P＜0.01)respectively.Compared with NC group,the left atrial diameter of SR group was also significantly greater,elevated by 60.6%[(48.48±5.05)mm vs.(30.18±2.85)mm,P＜0.01)].The level of plasma rennin activity(PRA),Ang Ⅱ and Aid in AF and SR patients was significantly higher than those of NC subjects(P＜0.01),and compared with SR patients,the level of those in AF patients was also significantly increased(P＜0.01,P＜0.05).Pearson correlation analysis revealed a positive correlation between the plasma level of PRA,Ang Ⅱ or Ald and the value of the left atrial diameter(r=0.277,0.485,0.431,P＜0.05,P＜0.01,P＜0.01).Multiple liner stepwise regression analysis showed that plasma Ang Ⅱ and Ald were the important risk factors that affected left atrial diameter in patients with rheumatic mitral stenosis(Bate=0.362,0.261,P＜0.01,P＜0.05).Conclusion Patients with rheumatic mitral stenosis are characterized by the activation of circulating RAAS,and the plasma Ang Ⅱ and Ald may contribute to left atrial structure remodeling.
