RESUMEN
Objective To determine whether the candidates who are disqualified because of arrhythmia during medical selection of flying cadets in China are qualified or not according to United States Air Force ( USAF ) Medical Standards Directory( MSD) , in order to raise suggestions on revising PLAAF medical selection of flying cadets.Methods ECG was performed on all candidates who participated in the final stage of medical selection of flying cadets, and they were considered qualified or not according to USAF MSD.Results Arrhythmia accounted for the largest proportion of cardiovascular diseases( CVDs) in PLAAF medical selection of flying cadets,the constituent ratios of CVDs from 2012 to 2015 were significant different (P<0.01).There were differences between the two countries and the outcome of 81.48%of the candidates disqualified for premature systole in PLAAF was unknown according to USAF MSD.Conclusion There are some differences in medical selection standards of flying cadets between PLAAF and USAF, and we could revise PLAAF standards with reference to USAF standards.
RESUMEN
Objective To assess the inlfuence and safety of early atorvastatin sequential therapy in coronary heart disease (CHD) patients underdoing elective percutaneous coronary intervention on selected indicators of inflammation and serum lipids. Methods A total of 88 CHD patients who got ready to receive the elective percutaneous coronary intervention (PCI) were divided in two groups at random:The sequential dose group was called group A (atorvatatin 80mg as loading dose ,40 mg/d for 1 month after PCI and 20 mg/d subsequently, n=43), and the ordinary dose group was called group B ( atorvastatin 20 mg/d, n=45). During the follow-up, blood samples were taken at baseline, 3 days,1 month, 3 months and 6 months for myeloperoxidase (MPO), matrix metalloproteinase-9(MMP-9), serum lipids, serum alanine aminotransferase (ALT), glutamyl endopeptidase (GGT) and creatine kinase (CK) levels. Main adverse cardiac events and adverse effects were also analyzed. Results Compared with the baseline, the level of low-density lipoprotein-cholesterol (LDL-C) and total cholesterol (TC) was signiifcantly decreased in both two groups after treatment (P 0.05). Reduction in MMP-9 also showed signiifcant in both groups after treatment (group A:F=46.911, P=0.00;group B:F=19.156, P=0.00). The adverse effects had no signiifcant differences between the 2 groups (P>0.05). Conclusions The atorvastatin sequential theapy in CHD patients undergoing elective percutaneous coronary intervention could decrease serum lipids signiifcantly. Pretreatment with atorvastatin for patients undergoing PCI could inhibit inlfammation. The MACE and adverse effects were similar between the two groups.
RESUMEN
OBJECTIVE: Computer has become an important tool in medical works. However, application ability of clinical physicians is imbalanced with the fast development of information technology (IT) system. Therefore, it is necessary to explore a bridge between researchers and integrate decentralized IT resources. Based on this survey, we provide some views concerning IT applying in medical procedures. METHODS: The correlated computer information was collected from a patient with coronary heart disease from early diagnosis, interventional therapy to coronary bypass surgery, until rehabilitation. The medical staffs were investigated from the general status, computer skills, knowledge structure, as well as the acceptance degree of computer application to measure computer skills. RESULTS: The correlated computer information was characterized by large soft variability, a large time span, and various date categories with more dynamic data or three-dimensional data. The investigation of computer knowledge demonstrated that the lack of IT knowledge resulted in poor outcome in their appointed tasks. From the view of self-assessment of IT knowledge, nursing staff and technician exhibited deficiency IT knowledge than doctors, who learned from department training, self-study or internet. Resident physicians and attending physicians were familiar with office system, so they were satisfied with IT skills. In contrary, nurses and majority of high-ranking professor or chief physicians were found difficult to study IT skills. However, most nurses were fond of their office system. The results also demonstrated that people aged 31 -40 years were easy to receive IT system. CONCLUSION: It is very important to enhance the cooperation between computer researchers and medical users for the treatment of coronary atherosclerotic heart disease.
RESUMEN
The arterial lesions of lower extremities in patients with diabetic foot ulcers were extensive.The majority of below-knee arteries showed severe stenosis, even complete occlusion.Interventional therapy of femoral artery was effective in improving arterial blood perfusion and remission of the pain and numbness.After therapy, the skin temperature and ankle brachial index (ABI) were increased, healing of ulcer was enhanced and intermittent claudication was ameliorated.Percutaneous transluminal angioplasty of femoral artery was effective in improving arterial blood perfusion of the lower extremities with foreseen curing efficacy.
RESUMEN
@#Objective To observe the effect of intraaortic balloon pump (IABP) on tolerance of percutaneous coronary intervention (PCI), life signs of patients with acute myocardial infarction (AMI) during emergency PCI performed.Methods46 AMI patients complicated with or without cardiogenic shock were put on IABP at same time of coronary angiography when emergency PCI performed, and tolerance of PCI, blood pressure, heart rate and immediate death rate of patients were observed before and after operation.Results45 cases had IABP successful and 1 case failed. 40 patients (86.96%) could endure whole emergency PCI process, the total death rate was 10.87%. 66.67% of patients with obvious cardiogenic shock could endure emergency PCI, the death rate was 33.33%; 94.12% of patients without cardiogenic shock could endure PCI treatment and the death rate was 2.94%. 35 cases completed PCI treatment and the successful rate was 85.36%.ConclusionPCI supported by IABP can prevent AMI patients from cardiogenic shock, ease symptoms of patients complicated with cardiogenic shock, improve the tolerance and successful rate of the PCI treatment, and decrease immediate death rate.

Objective To observe the changes in plasma C type natriuretic peptide(CNP) and C reaction protein(CRP) levels and the preventive effect of exogenous CNP on vascular stenosis in a diabetic rabbit model after femoral artery injury.Methods After setting up an animal model of diabetes,the rabbits were divided into the control group(n=8),artery injury group(n=8) and CNP treatment group(n=8).Enzyme-linked immunosorbent assay was used in determination of plasma CRP and CNP concentration.Histological changes in the femoral artery wall were evaluated by HE staining to determine the degree of stenosis.Results The post operative CRP concentration of the artery injury group compared with CNP treatment group was 13.81?4.30 ?g/mL vs 8.43?0.61 ?g/mL(P
