OBJECTIVE To investigate the pathogens distribution and their antibiotic resistance in critically ill patients with pulmonary infection.METHODS Totally 171 isolates from sputa were studied and the drug sensitive test was analyzed in 103 critically ill patients.RESULTS These results showed that 29 G+ bacteria strains occupied 17.0%,there were 15 Staphylococcus aureus strains,11 S.epidermidis strains and 3 Enterococcus strains,respectively.In 107 G-bacteria strains occupied 62.6% were composed Stenotrophomonas maltophilia,Acinetobacter baumannii,Burkholderia cepacia and Klebsiella pneumoniae,and 35 strains were fungi,accounted for 20.5%,the main fungi were Candida albicans and C.tropicalis.The result of drug sensitive test showed that there were high rates of multiple drug resistance in most bacteria strains,but there were different drug resistance rates to different antibiotics.CONCLUSIONS G-bacilli play an important role in the pulmonary infections of these critically ill patients,the opportunistic pathogens,such as S.maltophilia are the main G-pathogens,and there are high percentages of drug resistance.The other bacteria such as S.aureus,K.pneumoniae,etc,have a multidrug resistance.Inspecting pathogens and studying the trend of their drug resistance are very important in reducing drug abuse and decreasing the rate of infection in hospital.

Objective:To observe the influence of Danhong injection on interleukin-17 (IL-17)expression after percu-taneous coronary intervention (PCI)in patients with ST segment elevation myocardial infarction (STEMI),and ex-plore its protective effect on myocardial ischemia-reperfusion injury (MIRI)after PCI.Methods:A total of 300STEMI patients undergoing PCI in department of cardiology were selected.They were randomly divided into routine treatment group (n=150)and Danhong injection group (n=150).Enzyme linked immunosorbent assay (ELISA) was used to measure levels of IL-17 and IL-6. Results:There were no significant difference in expression levels of IL-17 and IL-6 between two groups before PCI (P >0.05).On 12h after PCI,IL-17 levels of two groups signifi-cantly rose (P <0.05),then gradually declined,IL-17 and IL-6 levels in routine treatment group were still signifi-cantly higher than those of before PCI (P <0.05),but those of Danhong group were not significantly different from before PCI (P >0.05).Total effective rate of Danhong group was significantly higher than that of routine treat-ment group (92.7% vs.81.3%,P <0.05).Compared with routine treatment group on 72h after PCI,there were significant reductions in levels of IL-17 [(31.4±6.1)ng/ml vs.(23.2±4.3)ng/ml]and IL-6 [(60.3±11.6)ng/ml vs.(42.7±8.4)ng/ml],significant rise in left ventricular ejection fraction [(43.6±4.5)% vs.(53.7±5.6)%] and significant reduction in myocardial infarction area [(22.7±4.3)% vs.(17.2±3.7)%]in Danhong injection group,P <0.05 all.Conclusion:Danhong injection decreases expressions of IL-17 and IL-6,it may be mechanism improving MIRI after PCI,thereby diminishes myocardial infarction area,and improves heart function,which is worthy extending.

To determine appropriate surgical methods and flaps to apply plastic surgery of facial defects. Several plastic methods were introduced progressively to eight cases. From simple to complex, we discussed the direct suture, relaxation suture, Z-flap, flap-footed, combined or multiple flaps, and free flap method to decrease the tension in wounds. The skin and flaps were successful in all eight cases and healed the wounds. It is important to choose appropriate surgical techniques and flaps to repair facial injuries.

0.05). CONCLUSIONS The pathogenic bacteria from VAP subglottic secretion are mostly Gram-negative rods, in which the dominant bacteria are A. baumannii, P. aeruginosa, S. maltophilia, K. pneumoniae and Escherichia coli. Most of them are multi-drug resistant. The kinds of pathogenic bacterial strains in subglottic secretion and lower respiratory tract secretion are not only consistent but also similar to each other in terms of composition and drug resistance.

Objective To study the current management strategy for colorectal injuries. Methods The clinical data of 86 consecutively admitted patients with penetrating colorectal injuries were retrospectively reviewed. Results Most injuries were of closed type. Iatrogenic colon injury accounted for 14%. There were 61 patients (71%) associated with other abdominal organ injuries. Operations were performed in all patients. Seventy six patients were treated with primary repair or resection and anastomosis, and 10 with diverting colostomy. In recent 10 years mortality rate dwindled from 10% to 4%(2/46). Mortality was most often caused by hemorrhagic shock, associated organ injuries or severe secondary infection. Conclusions Most colorectal traumas are blunt closed type in China. Primary repair or resection and anastomosis at the time of initial exploration is most often used for colorectal injuries. Indications for diverting colostomy are severe shock, heavy intra abdominal contamination, poor condition, and rectal injury. Fecal peritonitis should be effectively prevented and treated.

Objective To prepare gadolinium-loaded stearic acid grafted chitooligosaccharide (COSSA-DTPA-Gd) and evaluate its micelle properties,cytotoxicity,relaxation rate in vitro,and pancreatic tumor in vivo imaging.Methods Stear ic acid grafted chitooligosaccharide (COSSA) was synthesized by acetylation reaction between stearic acid and chitooligosaccharide.Diethylenetriaminepentaacetic dianhydride (DTPA) was conjugated to the residual amino groups of COSSA,then Gd3+ was chelated to obtain the final product.The micelle properties were measured using an electron microscopy and a laser particle sizer.The MTT assay was adopted to determine cytotoxicity.The in vitro relaxation rate and in vivo imaging of pancreatic tumor were evaluated using an MR scanner.Results COSSA-DTPA-Gd could self-assemble into stable micelles in aqueous solutions with a critical micelle concentration of (5.12±0.43)μg/ml.The micelles had positive charge and exhibited roughly spherical shape with a mean diameter of (58.3± 5.7)nm.The content of Gd3+ in COSSA-DTPA-Gd was 330.31 μmol/g.The nanoprobe and Magnevist,the commercial formulation,showed similar cytotoxicity (P＞0.05).The cell survival rate within 24 h were higher than 85％.The in vitro relaxation rate of COSSA-DTPA-Gd was 8.23 mM-1 ·s-1.After intravenous injection,COSSA-DTPA-Gd showed a better positive contrast-enhancing effect for pancreatic tumor than Magnevist.The MR images at the tumor periphery was rapidly enhanced,while a slow increase in image quality was observed in tumor core.Conclusion The prepared COSSA-DTPA-Gd can be used for efficient MR imaging of pancreatic tumor.

BACKGROUND:Many internal fixations,such as dynamic hip screw,Gamma screw,proximal femoral nail,angle steel plate,as well as locking proximac femoral plate,are utilized in treating intertrochanteric fractures,especially the dynamic hip screw However,the failure rate is gradually increased.OBJECTIVE:To explore the application and clinical efficacy of total hip replacement for the treatment of elderly intertrochanteric fracture fixation after failure of dynamic hip screw.METHODS:A total of four cases with intertrochanteric fractures were treated by total hip replacement after failure of dynamic hip screw fixation was selected.According to Evans typing,one case were type Ⅱ,two cases were type Ⅲ A,and one case was typeⅢB.Internal fixation displacement could be found at half to 1 year after dynamic hip screw fixation.Because of bone disunion,coxa adducta and pain,the patients could not walk.Sequentially,total hip replacement was performed with 45°abduct angle and10°-15°anteversion angle The clinical efficacy was evaluated by Harris scoring criteria.RESULTS AND CONCLUSION:All the cases were operated smoothly,with 1.5-2 hour operation duration and 400-600 mL blood loss.No case appeared allergic response to bone cement.By 3-12 months follow-up,4 successful operative cases do not appear prosthesis loosening,subsidence and are satisfied with well hip function.The average Harris score were 81 points.The results revealed that application of total hip replacement after the failure of DHS in elderly intertrochanteric fracture fixation,which shortened the time patients stay in bed to reduce complications and improved the hip joint function.

OBJECTIVE:To provide reference for further promoting the rational use of antimicrobial drugs in the rural commu-nity health service stations. METHODS:4 800 prescriptions were collected from 8 community health service stations affiliated to our hospital from Jan. 1,2012 to Dec. 31,2014,the use of antimicrobial drugs in the prescriptions was statistically analyzed and the indicators were compared before and after intervention. RESULTS:The proportion of use of antimicrobial drugs in these com-munity health service stations was decreased from 52.88%in 2012 to 30.38%in 2014;the clinical diagnosis of prescription of anti-microbial drug was mainly respiratory infections;what the most used types of antibacterial drugs was cephalosporins;and the pro-portion of antimicrobial drug of irrational use was decreased from 43.50%(368/846)in 2012 to 22.84%(111/486)in 2014. CON-CLUSIONS:The combination of technique and administrative intervention is remarkable. However,the unreasonable use of antibac-terial drugs still exists. Therefore,related training should be organized,and the proportion of use of antimicrobial drugs should in-cluded in the performance appraisal to further improve the use level of antimicrobial drugs in the rural community health service sta-tions.
