To explore the effects of remote ischemic preconditioning on myocardial injury and prognosis after percutaneous coronary intervention (PCI) in patients with acute coronary syndrome.The study was a single center, prospective, randomized, controlled study. A total of 184 patients with unstable angina undergoing elective PCI were randomly assigned to remote ischemic preconditioning group (induced by four times of 5-min inflations of a blood pressure cuff to 200 mmHg around the upper arm, followed by 5-min intervals of reperfusion at 1 h before PCI therapy) or control group (an uninflated cuff around the arm). Successful completion of the PCI eventually included 130 cases of patients, including 72 cases in the remote ischemic preconditioning group and 58 cases in the control group. CK-MB, cTnI, sICAM-1, sVCAM-1 and Hs-CRP levels were measured at 6 am. of the day operating PCI and at 24 h after PCI in the two groups. Major adverse cardiac events were recorded of two groups of patients in the postoperative 6 months. (MACE, including recurrence of angina pectoris, myocardial infarction and death).There were no statistically significant differences in baseline indicators between the 2 groups. CK - MB, cTnI, sICAM-1, sVCAM-1 and Hs-CRP levels in patients with remote ischemic preconditioning group were significantly lower than those form the control group after PCI (p0.05), but there were no significant differences between the occurrence of MACE in the postoperative 6 months (p0.05).Remote ischemic preconditioning can reduce PCI related myocardial injury and protect vascular endothelial function.

Acinetobacter baumannii is one of the most important nosocomial pathogens, and its multiple antibiotic resistance has emerged as an obstacle in the treatment of these infections worldwide.To identify risk factors of mortality for A. baumannii bacteraemia.A retrospective cohort study of 72 patients with significant A. baumannii bacteraemia was conducted to evaluate risk factors for mortality.The median age of the 72 enrolled patients was 48 years, 96% of the cases were hospital-acquired, and the bacteraemia-related mortality rate was 29% (21 of 72 patients). Univariate analysis revealed that the risk factors for mortality included: an elevated acute physiology and chronic health evaluation (APACHE II) score, receipt of in vitro ineffective definitive antimicrobial therapy, in vitro A. baumannii resistance to cefoperazone/ sulbactam, neutropenia, and presentation with septic shock. Multivariate analysis reveals that the independent risk factors for mortality are neutropenia and elevated APACHE II scores.Risk factors such as neutropenia and elevated APACHE II scores are found to be associated with higher mortality rates of A. baumannii bacteraemia. Further study is necessary for the determination of optimal strategies for both the prevention and treatment of these infections.

A series of 18 patients of transaxillary incision augmentation mammoplasties has been presented. The axillary incision was 3.5 to 4 cm long and healed inconspicuously. The silicon gel implants were put in under pectoral major muscle. Follow-up time was six months to 4 1/2 years. The results of all patients were satisfactory. All patients were graded into Baker's I. No capsular contraction was developed. This obvious difference between Chinese women and western women of capsular contraction after augmentation mammoplasties may be due to the difference of human race. But a future research should be designed and performed.
