Objective To report and analyze the changes of bacterial species and resistance to antibiotics in the burn center from 1993 to 2007. Methods Bacterial identification and susceptibility test were performed by applying VITEK-AMS system. Results A total of 4 762 strains were isolated,including 60 species of 21 genera. Pseudomonas aeruginoasa (PA) was the most common organism (36. 79%), and its isolating rate was 36. 79%; in 2006, the highest isolating rate of PA was 51.6%.The isolating rate of Staphylococcus aureus was 14.09 %, next to that of PA; followed by Enterococci faecalis, Acinetobacter, Escherichia coli, Enterococci faecium, Enterobaeter cloacae and Staphylococ-cus epidermidis, and the 8 kinds of germs shared 78. 12% of bacterial isolates (3 746/4 762). The an-tibiotic resistance rate of Pseudomonas aeruginosa was increasing year by year; it was vitally resistant to the third generation eephalosporins and imipenem. Conchtsion The predominant species of bacteria from burn center is Pseudomonas aeruginosa, and RA isolates are multi-resistant to antibiotics. The i-solating rates of Enterococeus faeealis and Acinetobacter are increasing. This implied the importance of rational and correct use of antibiotics about control of burn infections as well as avoidance of abusage of broad-spectrum antibiotics.

BACKGROUND:Mental material has shadow intervention effects on multi-slice helical CT (MDCT).Mental wall thickness and lumens inner diameter in stent structure can significantly affect longitudinal axis imaging quality of MDCT target vessel stent.However.there are few studies involved in this aspect.OBJECTIVE:To analyze the effect of various coronary stent materials and structures on patency images of target vessel by MDCT evaluation,and to provide clinical evidences for improving stent technique.DESIGN,TIME AND SETTING:The comparison observation was conducted at the Shenzhou Hospital,Shenyang Medical College.and Shengjing Hospital,China Medical University from January 2006 to December 2008.PARTICIPANTS:A total of 139 patients with coronary heart disease who were treated with stent implantation were divided into material and construct groups (227 stents were implanted).There were 92 stainless steel stents,135 nick-eltitanium alloy stents,85 thin mental wall stents (<140μm).142 thick mental wall stents (≥140μm).71 small diameter stents (<3 mm),and 156 big diameter stents (≥3mm).METHODS:During following up,patients were checked using 64-slice helical CT and routine coronary arteriongraphy to compare patency images of target vessels in the two groups.MAIN OUTCOME MEASURES:MDCT was scored by four-mark standard to evaluate sensitivity,specificity,accuracy,positive and negative predictive values of MDCT.RESULTS:A total of 227 stents were implanted into 139 patients.CT images of stainless steel stent group were poorer than nickel-titanium alloy group,and the indicators including image score,sensitivity,specificity,positive and negative predictive values of the stainless steel stent group were significantly less than nickel-titanium alloy group (P<0.05).CT images of thick-wall stent were poorer than thin-wall stent,while the indicators including image score,sensitivity,specificity,positive and negative predictive values of the thick-wall stent were significantly less than thin-wall stent (P<0.05).CT images of small-diameter stent were poorer than large-diameter stent,while the indicators including image score,sensitivity,specificity,positive and negative predictive values of the small-diameter stent were significantly less than large-diameter stent (P<0.05).CONCLUSION:Materials,wall thickness and diameter of coronary stent may influence images of target vessels via MDCT evaluation.

Objective To evaluate the efficacy of gabapentin for prevention of post-thoracotomy pain syndrome (PTPS).Methods Sixty-nine ASA physical status Ⅰ or Ⅱ patients of both sexes,aged 46-69 yr,weighing 47-78 kg,scheduled for elective resection for lung cancer under general anesthesia combined with epidural block,were randomly divided into 2 groups using a random number table:group A (n =36) and group B (n =33).In group A,gabapentin 300 mg was given orally at 2 h before operation and gabapentin 100 mg was given orally three times a day from 1st day after operation until 10th day after operation.Group B received placebo instead of gabapentin.Epidural blockade with ropivacaine and sufentanil was performed before induction of anesthesia and the level of block was controlled at T4-10.Patient-controlled epidural analgesia (PCEA) was performed within 3 days after operation and VAS scores were maintained ≤ 3.The development of pain (numeric rating scale score ＞ 4) within 6 months after operation and the duration were recorded.The consumption of propofol and remifentanil during operation and the number of attempts for PCEA after operation were recorded.The adverse reactions such as postoperative drowsiness,dizziness,fatigue were also recorded.Results Compared with B group,the incidence of pain within 6 months after operation was significantly decreased,the duration of pain was shortened (P ＜ 0.05),and no significant changes were found in the consumption of propofol and remifentanil during operation and the number of attempts for PCEA after operation in A group (P ＞ 0.05).No adverse reactions developed in group B.Mild dizziness and fatigue occurred in 2 patients in group A.Conclusion Gabapentin (continuous application at 2 h before operation and 10 days after operation) can reduce the development of PTPS in patients with no obvious adverse reactions.
