Objective To investigate whether BNP(brain natriuretic peptide) could be relatively objective index for comprehensive risk stratification of exercise rehabilitation nursing in young and middle myocardial infarction patients. Methods BNP concentration and LVEF were measured respctively in young and middle myocardial infarction patients. Then the risk stratification was administrated based these index respectively and Barther Scores and significant statistical differences were calculated according to homogeneity test for variance. Results Blood BNP concentrations in acute phase among the divided group based on EF risk stratification were significant difference,hence the standard deviation is large,which led to variance nonhomogeneity,and stracification difference between groups is not clear and across-talking. Exercise rehabilitation nursing scores based on echocardiography EF value had significant difference even veariance is nonhomogeneity,hence the differ-ence is not clear beween groups.Exercise rehabilitation nursing scores based on BNP was administrated and significance is clear beween groups. Conclusions BNP concentration and LVEF value had certain relationship and cross-talking among them.Risk stratification based on BNP concentration had objective instructions for exercise rehabili tation nursing in actue infarction myocardial pa-tients.

Objective To evaluate the changes of morphology, hemodynamics and endothelial function of the dorsal artery of foot in patients with early-stage type 2 diabetic mellitus (T2DM) by high-resolution ultrasound. Methods The changes of morphology, homodynamics and endothelial function of the dorsal artery of foot were measured in 25 elderly and 35 non-elderly T2DM patients and 35 elderly and 30 non-elderly healthy persons. Results (1) The change percentage of inside diameter of foot dorsal artery under reactive hyperemia situation was obviously reduced in elderly T2DM patients compared with elderly healthy controls [(10.52±2.79)% vs. (15.43±4.69)%, P<0.01] and there was significant difference between non-elderly T2DM versus healthy persons [(12.89±4.68)% vs. (17.97±4.61)%, P<0.01],and it was lower in elderly versus non-elderly T2DM ones (P<0.05). The change percentage of inside diameter of foot dorsal artery wassignificantly lower in elderly T2DM versus healthy subjects after taning nitroglycerin [(12.40± 3.23)% vs. (16.11±5.74)% , P<0.01]. (2) Compared with control groups, the intima-medial thickness (IMT) of dorsal artery of foot was thickened significantly, and the peak reverse velocity (PRV) in early diastole, the velocity in end diastole (EDV) and pulsatility index(PI) were reduced significantly in T2DM groups (P<0.05). The peak systolic velocity (PSV) had no significant differences among all the groups (P>0. 05). (3) In T2DM groups, the PI was correlated positively with the change percentage of inside diameter of dorsal artery of foot under reactive hyperemia situation (r=0.79, P<0.01) and after having taken nitroglycerin (r=0.71, P<0.01), respectively. Conclusions The changes of morphology, hemodynamics and the injuries of endothelial function of the dorsal artery of foot can be detected in patients with early-stage T2DM byhigh-resolution ultrasound, which has clinical significance and applicable value.

Plaque rupture,platelet aggregation,and thrombogenesis are the main mechanisms of acute coronary syndrome (ACS),and inflammation factors play key roles in plaque unstability.Psychological stress promotes acute inflammatory response,leading to increased circulating levels of C-reactive protein (CRP),IL-6,and serum intercellular adhesion molecule (sICAM)-1.But it is not clear that whether psychological stress has a direct effect on atherosclerotic plaque stability.The purpose of this study was to investigate effects of chronic psychological stress on inflammatory marker (ICAM-1 ) in atherosclerotic plaque,and inflammatory markers in peripheral blood.Materials and methods Sixty male rabbits were randomized into 2 groups:the control group (n =10) and the atherosclerotic group (n =50).The latter were fed on high fatty diet and were given a large dose of vitamin D3 (3 600 000IU/kg) via intraperitoneal injection.After 8 weeks,the atherosclerotic model was estaslished.Then the 50 atherosclerotic model rabbits were divided into 3 subgroups:no-stress subgroup (n = 16),physiological stress subgroup (n = 16) and psychological stress subgroup (n =18).In physiological stress subgroup and psychological stress subgroup,drinking was cut from twice a day to once a day.At the same time,psychological stress subgroup was given empty bottle stress,and this process lasted for 2 weeks.One hour after the last stress,the blood samples were collected and the serum levels of CRP,IL-6 amd ICAM-1 were tested by radioimmunoassay or enzyme linked immunosorbent assay.The aorta and heart were extracted for pathology examination,and the express of ICAM-1 was tested by immunohistochemical examination.Results (1) After effective atherosclerotic animal model construction,the expression of ICAM-1 in aorta was higher in atherosclerotic group than that in control group (P<0.01),and was notably higher in psychological stress subgroup than that in no-stress subgroup or in physiological stress subgroup (2.18±0.17 vs 1.58±0.22,1.22±0.15,P<0.001,respectively).The expression in physiological stress subgroup was higher than that in no-stress subgroup (584±0.22 vs 1.22±0.15,P=0.001).(2) The serum level of IL-6 (51.80±4.60 pg/ml vs 27.60±4.19 pg/ml,8.01±1.39 pg/ml,7.83±1.37 pg/ml),sICAM-1 ( 1.24±0.25 vs 0.85±0.09,0.62±0.17,0.57±0.11),CRP ( 1.004±0.37 vs 0.90±0.29,1.01±0.22,0.71±0.13) in psychological stress group were significantly higher than that in other groups (All P<0.05).There was a positive relationship between the serum level of CRP,IL-6 and ICAM-1 and the expression of ICAM-1 in aorta wall ( r =0.59,r =0.75,r =0.87,P<0.01,respectively).Conclusions Psychological stress induces an increased expression of ICAM-1 in aortic atherosclerotic plaque,a higher serum level of CRP,IL-6,and sICAM-1 expression.Psychologial stress has a direct effect on the transition from stability to unstability through in-plaque and out-plaque inflammation.The serum level of CRP,IL-6 and ICAM-1 can reflex the inflammatory degree in atherosclerotic plaque.(J Geriatr Cardiol 2008;5:235-242)

Objective To analyze the severity of coronary artery lesions and the prognosis in patients with low levels of free triiodothyronine (fT3)undergoing coronary angiography (CAG). Methods From August 2011 to August 2012, 600 consecutive suspected patients with coronary heart disease (CHD) who undergone CAG were selected. The patients were divided into two groups based on thyroid function prior to CAG:euthyroidism group (450 patients) and low T3 group (150 patients). All the patients underwent elective coronary angiography, then the severity of coronary artery lesions was assessed by the Gensini scores , and the patients were followed up for cardiovascular events. Results The incidence rate of CHD in low T3 group was significantly higher than that in euthyroidism group (P=0.01). Multiple variables logistic regression analysis showed that fT3 was a protective factor for CHD (OR = 0.351,P < 0.001); The severity of coronary artery lesions was greater in low T3 group than in euthyroidism group (P < 0.001). The mean duration of follow-up was (15.4 ± 3.6) months; the incidence of the composite end-point (death, non-fatal myocardial infarction and target vessel revascularization ) was significantly higher in low T3 group than in euthyroidism group (P=0.023). Conclusions Patients with a decreased T3 level has a higher incidence rate of CHD , an increase in the severity of coronary artery lesions , and a poorer prognosis.
