Objective To explore the predictive factors of death in patients with AMI after emergency PTCA Methods PTCA were performed in 43 patients with AMI from June 1996 to March 2001, including 30 males and 13 females with aged 27-80 (mean 60 5?12 6) years old 7 Patients died inhospital Results The mortality of patients with killip 3-4, cardiogenic shock (58 3%, 44 4%) is higher than that of patients without such complications Compared with the patients without total occlusion, the patients with total occlusion have higher mortality (20 6% vs 0%) The mortality of patients with acute thrombolysis during PTCA is higher than that of patients without acute thrombolysis (40 0% vs 9 1%) Conclusion Killip 3～4, cardio genic shock, total occlusion, acute thrombolysis are the predictive factors of in hospital death in patients with AMI after PTCA

Objective To assess the impact of patients's sex on outcome in patients with acute myocardial infarction (AMI) treated with percutaneous coronary intervention (PCI). Design: Inception cohort of 232 patients (44 women and 188 men) who were admitted with a diagonosis of AMI to CCU between June 1996 and April 2002 in Heart Center of Dalian Medical University. Results Compared with men, women were older (66?9 vs 58?11, P

Objective To optimize the antibacterial drug regimen in ICU common staphylococcal infection.Methods The pharmacokinetic and pharmacodynamic parameters of antibacterial drugs were collected in combination with the hospital ICU anti-microbial drug resistance monitoring reports from the national antimicrobial resistance investigation net (Mohnarin)of the Ministry of Health and the performance standards for antimicrobial susceptibility testing (2013)issued by the clinical and laboratory stand-ards institute (CLSI),the minimum inhibitory concentration (MIC)of staphylococci was set by using the discrete uniform distribu-tion method and 16 kinds of administration regimens with 6 antimicrobial agents were worked out.The best initially antimicrobial regimen was optimized by using the pharmacokinetic and pharmacodynamic models and Monte Carlo simulations of cumulative frac-tion of response (CFR)from 5 000 patients.Results The alternative initially drug regimens to the infectious bacteria were:linezolid 0.40 g twice daily and vancomycin 0.75 g twice daily for staphylococcus aureus;amikacin 0.60 g once daily and linezolid 0.40 g twice daily,and vancomycin 0.75 g twice daily for hemolytic staphylococci and staphylococcus epidermidis;linezolid 0.40 g twice daily and vancomycin 0.75 g twice daily for methicillin-resistant Staphylococcus aureus;ampicillin/sulbactam 1.50 g 4 times daily, cefuroxime 0.75 g 4 times daily,amikacin 0.60 g once daily,moxifloxacin 0.40 g once daily for methicillin-sensitive staphylococcus aureus.Conclusion In the Staphylococcus aureus infection occurred in ICU,if which being methicillin-sensitive could be deter-mined,ampicillin/sulbactam,cefuroxime,amikacin and moxifloxacin could be selected for treatment,and linezolid or vancomycin could be selected for treating possible methicillin-resistant Staphylococcus aureus infection or undetermined whether being methicil-lin-resistant Staphylococcus aureus infection.

Objective To evaluate the clinical features of in-stent restenosis after drug eluting stent (DES) implantation and investigate the relationship between different patterns of DES restenostic lesions and long-term prognosis.Methods All scoronary heart disease patients who underwent repeated pereutaneous coronary intervention (PCI) for DES in-stent restenosis from September 2006 to December 2009 were enrolled.All patients were divided into focal group and non-focal group according to the pattern of restenosis.All patients were prospectively followed up for major adverse cardiovascular event (MACE) including death,repeat PCI and myocardial infarction.Results Totally 88 patients (40 with focal restenosis,48 with non-focal restenosis) were enrolled.There were no significant differences between two groups in age,gender,risk factors,clinical presentation and medical therapy (P ＞ 0.05).Compared with that in focal group,the patients in non-focal group had a higher portion of in-segment restenosis [58.3％ (28/48) vs.12.5％(5/40),P＜ 0.01],higher stenosis rate [(78.1 ± 10.0)％ vs.(70.0 ± 9.7)％,P ＜ 0.01],more need for another DES[81.2％(39/48) vs.17.5％(7/40),P＜ 0.01],and longer stent implanted [(25.0 ± 7.0) mm vs.(17.4 ±3.4) mm,P ＜0.01].After following up for (2.2 ± 1.0) years,there were no significant differences between two groups in MACE and each component (P ＞ 0.05),however,compared with that in focal group,there was a trend of increase in MACE in non-focal group[22.9％(11/48) vs.10.0％(4/40),P=0.092].Conclusion It suggests that patients with non-focal restenosis have a more severe lesion angiographically,which usually results in another DES implanted,and has a worse long-term prognosis.

Objective To study the prognosis and pre-procedural independent risk factors for pa-tients with no-reflow (NR) phenomenon during percutaneous coronary intervention (PCI). Methods Pa-tients with or without NR phenomenon during PCI procedures from January 2000 to January 2005 were studied retrospectively. The clinical data preoperative and the incidence of major adverse cardiovascular events (MACE) between the two groups were compared. Univariate analysis and multivariate Logistic analysis were used to select the risk factors for NR phenomenon. Retrospectively was reviewed for (35.8 ± 15.3)months. Results The NR group had more significant incidence of MACE. Multivariate Logistic analysis showed that the predictive factors for NR were (1) Smoke index ≥ 300(OR = 2.81,95%CI: 1.61-4.38 ,P =0.007). (2) Fasting blood glucose level before PCI ≥ 11.1 mmol/L (OR = 3.39,95%CI: 1.51-4.89,P = 0.000 ). (3) Absence of angina pectoris attack within one month before PCI (OR = 2.39,95%CI: 1.22-3.78,P = 0.009). Conclusions The prognosis is poor for the PCI patients with NR phenomenon. Those patients whose fasting blood glucose level before PCI ≥ 11.1 mm01/L, smoke index ≥ 300 and absence of angina pec-toffs attack within one month before PCI have higher incidence of NR phenomenon.

Objective:To investigate the intervention effect of binary coping strategy based on systemic interaction model on the postoperative survival quality of patients with oral cancer.Methods:A total of 99 patients with oral cancer admitted to the Department of Oral and Maxillofacial Surgery of a tertiary hospital from Jun 2021 to Jun 2022 was selected.They were randomly divided into the control group(50 cases)and the observation group(49 cases)with random number table method.The control group received routine nursing for oral cancer.On this basis,the observation group also received the binary coping strategy based on the systemic interaction model.The scores of UW-QOL quality of life scale and binary coping scale were compared between the two groups before surgery,at the 3rd and 9th weeks after surgery.Results:The UW-QOL scores of both groups at the 3rd and 9th weeks after surgery were lower than those at admission,and the UW-QOL score in the control group was lower than that in the observation group(P＜0.05).At the 3rd week after surgery,the score of coping with the partner in the observation group was higher than that in the control group(P＜0.05).At the 9th week after surgery,the total score,negative coping,stress communication,coping together,and supportive coping scores in the observation group were higher than those in the control group(P＜0.05).Repeated measures analysis of variance showed that there was an interaction between time and group for the total score of binary coping scale(P＜0.05).And there was a significant main effect of time and group on the total score of binary coping scale(P＜0.05).Conclusions:The quality of life of patients with oral cancer is poor.The binary coping strategy based on the systemic interaction model can improve the quality of life of patients,enhance the intimacy of patients with their partners,and contribute to the disease recovery of patients with oral cancer.
