Another 72 subjects without coronary heart disease (CHD) ,who received physical examination in our hospital during the same period ,were selected as non‐CHD con‐trol group .Serum concentrations of APN and HO‐1 were measured in all groups . The correlation among serum APN ,HO‐1 concentrations and severity of coronary lesion were analyzed .Results:Compared with non‐CHD con‐trol group ,there were significant reductions in serum concentrations of APN [ (15.27 ± 2.31) mg/L vs .(5.73 ± 0.88) mg/L] and HO‐1 [ (55.09 ± 8.63)μg/L vs .(23.17 ± 3.09)μg/L] in ACS group ,P<0.01 both .Compared with single vessel group ,there were significant reductions in serum concentrations of APN [(9.72 ± 1.13) mg/L vs . (7.05 ± 0.93) mg/L vs .(4.23 ± 0.52) mg/L] and HO‐1 [(38.16 ± 7.52)μg/L vs .(28.17 ± 5.31)μg/L vs .(20.32 ± 3.28)μg/L] in double‐vessel group and multi‐vessel group ,and those of multi‐vessel group were significantly low‐er than those of double‐vessel group ,P<0.05 or <0.01 .Linear regression analysis indicated that serum concentra‐tions of APN and HO‐1 were significant inversely correlated with severity of coronary lesion (B= -2.869 , -2.742 , P<0.05 ,<0.01 respectively) .Conclusion:Serum concentrations of APN and HO‐1 significantly reduce in ACS patients ,and their levels are significant inversely correlated with severity of coronary lesion ,so they are help‐ful to judging patient's condition and guiding treatment .

Objective: To analyze the correlation among serum adiponectin (APN), heme oxygenase-1 (HO-1) concentrations and severity of coronary lesion in patients with acute coronary syndrome (ACS). Methods: A total of 78 ACS patients, who hospitalized and received therapy in our hospital from Oct 2013 to Oct 2014, were enrolled as ACS group. According to severity of coronary lesion, they were further divided into single vessel coronary disease group (single vessel group, n=15), double-vessel coronary disease group (double-vessel group, n=37) and multi-vessel coronary disease group(multi-vessel group, n=26). Another 72 subjects without coronary heart disease (CHD), who received physical examination in our hospital during the same period, were selected as non-CHD control group. Serum concentrations of APN and HO-1 were measured in all groups. The correlation among serum APN, HO-1 concentrations and severity of coronary lesion were analyzed. Results: Compared with non-CHD control group, there were significant reductions in serum concentrations of APN [(15.27±2.31) mg/L vs. (5.73±0.88) mg/L] and HO-1 [(55.09±8.63) μg/L vs. (23.17±3.09) μg/L] in ACS group, P<0.01 both. Compared with single vessel group, there were significant reductions in serum concentrations of APN[(9.72±1.13) mg/L vs. (7.05±0.93) mg/L vs. (4.23±0.52) mg/L] and HO-1 [(38.16±7.52) μg/L vs. (28.17±5.31) μg/L vs. (20.32±3.28) μg/L] in double-vessel group and multi-vessel group, and those of multi-vessel group were significantly lower than those of double-vessel group, P<0.05 or <0.01. Linear regression analysis indicated that serum concentrations of APN and HO-1 were significant inversely correlated with severity of coronary lesion (r=-2.869, -2.742, P<0.05 both). Conclusion: Serum concentrations of APN and HO-1 significantly reduce in ACS patients, and their levels are significant inversely correlated with severity of coronary lesion, so they are helpful to judging patient’s condition and guiding treatment.

Objective To investigate the features of vascular damage in metabolic syndrome (MS) by a comparison of changes in vascular structure and function between spontaneous hypertension (SH) and MS in rats. Methods Pathological study of changes in arteries was carried out. The contractile response of aorta ring and the expression of RhoA, ROCK, eNOS and iNOS were also determined. Results Besides the thickening of arterial wall and proliferation of both intima and smooth muscle layer, marked infiltration of inflammatory cell appeared in large and medium arteries of MS rats, and obvious hyaline degeneration was found in mesenteric arterioles. Moreover, the relaxant response of aorta ring was weakened markedly in MS rats, while the contractile response increased in SH rats dramatically. The expression of RhoA, ROCK increased and that of NOS decreased in MS rats, but the up-regulation of the RhoA, ROCK expression was not as much as in SH rats. Conclusion The damage to both arterial structure and function was much more serious in MS rats than that in SH rats. Activation of RhoA/ROCK system and reduction of NOS expression might be involved in the mechanism.
