AIM:To evaluate complement activation in patients with all forms of acute coronary syndromes(ACS)and to examine the relationship between the degree of complement activation and myocardial injury.METHODS:The subjects were divided into 2 groups:110 ACS patients(group ACS)and 18 healthy persons(group control).One hundred and ten patients with ACS were divided into 3 sub-group:51 patients with ST-segment elevated myocardial infarction(STEMI),28 patients with non-ST-segment elevated myocardial infarction(NSTEMI)and 31 patients with unstable angina(UA).Complement 3(C3),complement 4(C4),troponin T(TnT)as well as creatine kinase MB(CK-MB)were evaluated.RESULTS:Plasma C3 and C4 peak levels were significantly higher in patients with STEMI [(1 525?302)mg/L and(423?123)mg/L] and NSTEMI [(1 516?289)mg/L and(396?68)mg/L] than those in patients with UA [(1 275?172)mg/L and(356?91)mg/L] and the control subjects [(1 072?196)mg/L and(182?73)mg/L](P

Objective To identify the prevalence and profile of psychological difficulties in a sample of women seeking the breast reconstruction, and to study the effect of the reconstructive surgery on their psychology.

The proportion of the abnormally psychological patients was counted, their personality characters were analyzed, and the postoperative psychological changes were obverved. Results It was found that the 64 percent of the breast-loss patients were in anxiety, 30 percent were in depression, and 18 percent were in body dysmorphic disorder. The characteristics of their personality were more extravert, sociable and easily emotional agitation. The scores in SES of the preoperative patients were 27.46±8.95, and those of the postoperative patients were 33.05±6.12 (P＜0.05). The scores in SBDDS of the preoperative patients were 25.74±13.23, and those of the postoperative patients were 18.22±8.08 (P＜0.05).Conclusion The proportion of the anxiety, depression and BDD is high in the breast-loss women, and the postoperative psychology of esteem and body dysmorphic disorder is improved effectively.
