Objective: To explore therapeutic effect of individualized cognitive training on improving cognitive function in aged patients with coronary heart disease (CHD) after percutaneous coronary intervention (PCI).Methods: A total of 92 aged CHD patients after PCI, who were diagnosed and treated in our hospital, were selected.According to random number table, they were randomly and equally divided into routine nursing group (n=46) and cognitive training group (n=46, received active individualized cognitive training based on routine nursing), both groups were observed for three months.Scores of Montreal cognitive assessment (MoCA), self-rating anxiety scale (SAS) and self-rating depression scale (SDS), and left ventricular ejection fraction (LVEF) were compared between two groups before and after nursing.Results: Compared with before nursing, after nursing, there were significant rise in LVEF and MoCA score, and significant reductions in scores of SAS and SDS in both groups (P<0.01);compared with routine nursing group, there were significant rise in LVEF [(51.87±4.89)% vs.(58.29±5.13)%] and MoCA score [(24.44±4.10) scores vs.(29.34±3.14) scores], and significant reductions in scores of SAS [(38.22±5.64) scores vs.(32.09±4.11) scores] and SDS [(37.22±4.98) scores vs.(30.56±5.68) scores] in cognitive training group, P<0.01.Training compliance of cognitive training group was significantly higher than that of routine nursing group (95.7% vs.82.6%, P=0.044).Conclusion: Individualized cognitive training can significantly improve training compliance after PCI, significantly improve cognitive function, relieve anxiety and depression, and enhance cardiac function in aged CHD patients.

【Objective】 To explore the relationship between preoperative anemia and perioperative red blood cell (RBC) transfusion and postoperative outcomes in patients undergoing mitral valve surgery. 【Methods】 The clinical data, laboratory findings, blood transfused and outcomes data of 493 patients who underwent mitral valve surgery in Fuwai Hospital in 2017 were collected by blood transfusion management system and retrospectively analyzed by SPSS. The patients were divided into anemia group (n=34, male Hb<120 g/L and female Hb<110 g/L) and non-anemia group (n=459) .The measurement data were statistically analyzed with t test or rank sum test, and enumeration data by Fisher test and Chi-square test, and then all analyzed by binary logistics regression. 【Results】 The incidence of anemia before mitral valve surgery was 6.90% (34/493). Perioperative erythrocyte dosage (U) (median), erythrocyte transfusion rate, ICU stay time (d) (median) and hospital mortality rate(%) in anemia group and non-anemia group were 4.00 vs 0.00 (OR: 2.55, 95% CI: 1.70~3.40, P<0.05), 67.65% vs 21.35% (OR: 12.98, 95% Cl: 5.21~31.15, P<0.05), 2.50 vs 2.00 (B: 0.71, 95% Cl: 0.08~1.33, P<0.05) and 5.88 vs 0.22(P<0.05)respectively. 【Conclusion】 Preoperative anemic is independently associated with perioperative RBC transfusion in patients undergoing mitral valve surgery, and may increase ICU length of stay and hospital mortality.

Objective To analyze the factors related to surgical caused infections in children for reducing the infection of operative site.Methods A total of 120 case-times of operation in this hospital were selected.The dynamical air colony number and colony number of surgical instruments were performed the dynamic monitoring.The bacterial colony in air and surface of operative instruments were performed the bacterial species analysis.Results The dynamical air colony number in class 100,1 000,10 000 operating room all presented as "N" character pattern distribution;at 1 h after operation beginning,the variation of air colony number in class 100 operating room was significantly higher than that in class 1 000 and 10 000 operating rooms(P＜0.05).The surface colony increase rate of sterile towel wrapped sterile operating instruments was significantly slower than that of the operating instruments directly exposing to air(P＜0.05).The surface colony increase rate of operating instruments scrubbed by 1％ povidone-iodine was significantly slower than that of operating instruments without scrubbing bloodstain and with scrubbing bloodstain by normal saline(P＜0.05).The bacterial species distribution in operating room air was consistent with that in operating instrument surface.Conclusion The operation caused infection in children is significantly correlated with the operating room bacterial colony number and operation time.
