OBJECTIVE To determine the rationality of application of antibiotic prophylaxis in perioperative period in Department of Orthopedics in order to find evidence for clinical proper practice.METHODS A total of 150 patients with perioperative administration of antibiotics were included for the clinical analysis of rationality use of the drugs.RESULTS All of the 150 patients were given antibiotics in the perioperative period.All together 26 kinds of drugs belonged to 8 categories were used.Only 4% of the patients started antibiotic administration 2 hours just before operation,while 88% were

OBJECTIVE To analyze and evaluate the comsumption of the antibacterial drugs during surgery operation in our hospital objectively.METHODS To carry out statistical analysis of antibacterial drugs from May to Dec in 2007.RESULTS The 93 percent of preventive usage of antibacterial drugs were in 2 hours after operation.The most was cephalosporins.CONCLUSIONS It is important to enhance the education of rational use and supervision.

BACKGROUND: The area of myocardial infarction is the determinative factor of acute myocardial infarction prognosis. Amelioration of blood transportation and replacement therapy can reduce infarction area. Bone marrow mesenchymal stem cells can differentiate into cardiovascular tissue and are easy to obtain. After cultured and expanded in vitro, they can become the ideal cells for cardiovascular replacement therapy.OBJECTIVE: To evaluate the therapeutic effect of intracoronary transplantation of bone marrow mesenchymal stem cells in the treatment of myocardial infarction. DESIGN: Self-control observation taking the patients as subjects.SETTING: Department of Cardiology, Department of Nuclear Medicine,Echocardiogram Room, Nanjing First Hospital Affiliated to Nanjing Medical University.PARTICIPANTS: Totally 20 patients with acute myocardial infarction who received the therapy of bone marrow mesenchymal stem cells transplantation in the Department of Cardiology, Nanjing First Hospital Affiliated to Nanjing Medical University during March 2003 to March 2004 were recurited. Informed consents were obtained from the patients, and the complete postoperative follow up was over 3 months. The patients include 15 male and 5 female, and they were aged (64±10) years.METHODS: All the patients underwent percutaneous coronary intervention (PCI) to treat infarction-related blood vessel. Autologous bone marrow was taken from the patients, then stem cells were extracted to be performed in vitro induction, differentiation and proliferation, and transplanted infarction-related blood vessel through coronary artery at the mean number of (21.7±30.14)× 107 within 2 weeks. Before and 3 months after transplantation of stem cells, patients underwent gated dual-isotopic myocardial perfusion/metabolic imaging (18-fluoro-2-deoxy-glucose, 18F-FDG) examination. Survived and necrotic myocardia were predicted and infarction area was obtained. At the same time, wall motion and heart function index were evaluated with ultrasound cardiography (UCG)examination, and they were re-checked 3 months after operation to evaluate the amelioration of wall motion and heart function index. A 5-point scale was used in the evaluation of gated dual-isotopic myocardial perfusion/metabolic imaging (18F-FDG) examination: point 0: normal, 1: sparse, 2:obviously sparse, 3: defected. Evaluative standard of UCG: point 1: normal,2: reduced, 3: obviously reduced, 4: no ventricular wall motion or paradoxical motion; Wall motion with 2 points or more than 2 points suggests it is improved.MAIN OUTCOME MEASURES: ① Results of gated dual-isotopic myocardial perfusion/ metabolic imaging (18F-FDG-SPECT); ②Infarctionrelated myocardial segment score and heart function index before and after stem cell transplantation of patients in ECG follow-up observation.RESULTS: All the 20 patients participated in the result analysis.Results of gated dual-isotopic myocardial perrusion/metabolic imaging (18F-FDG-SPECT): The myocardial perfusion defect area of 20 patients was significantly reduced after therapy than before therapy [(33±15)%,-(44±18)% ,P ＜ 0.05]; Metabolie defect area was significantly reduced after therapy than before therapy [(33±17)%, (43±21)% ,P ＜ 0.05];Before therapy, there were 199 segments, in which blood flow reperfusion was matched to glycometabolism defect, and they were determined as necrotic myocardium. After therapy, blood flow perfusion metabolism was improved in 79 segments, but blood flow perfusion and glycometabolism were not improved significantly in 120 segments (P ＜ 0.05). Results of UCG: ejection fraction of patients was significantly larger after therapy than before therapy [(53±8)%, (42±7)% ,P ＜ 0.05].CONCLUSION: Intracoronary transplantation of human bone marrow mesenchymal stem cells for treating myocardial infarction is simple to operate. After therapy, the infarction area is obviously reduced, myocardial blood flow perfusion and metabolism of necrotic area improve, myocardial segments without survival determined before operation reduce sigrificantly and the heart function of patients improve.

Objective:To learn about the cognition of iodine deficiency disorders (IDD) prevention knowledge among key population in the IDD area of Jilin Province, and to evaluate the effect of health education.Methods:From 2015 to 2019, 10 counties (cities, districts, hereinafter referred to as counties) in Jilin Province were selected as project counties every year. Public health education covered the entire project county. In each project county, 3 project townships were selected, and students of grades 4-6 were selected from the central primary schools of each project township for school health education. In each project township, 3 project villages were selected to carry out community health education. Before and after health education, 30 fifth-grade students were selected from the central primary school of each project township, and 15 housewives were selected from the vicinity of each primary school to conduct a questionnaire survey on IDD prevention knowledge.Results:After health education, the overall awareness rate of IDD prevention knowledge among primary school students and housewives in Jilin Province was 96.26% (13 324/13 842) and 96.40% (6 819/7 074), which was significantly higher than that before the intervention [65.36% (9 032/13 818) and 71.26% (5 039/7 071)], and the differences were statistically significant (χ 2 = 4 258.34, 1 647.92, P < 0.001), and the awareness rates of primary school students and housewives increased by 30.90% and 25.14%, respectively. Conclusion:Health education has significantly increased the awareness rate of IDD prevention knowledge among key populations in Jilin Province, and is an important measure to ensure the continuous elimination of IDD.
