Objective To explore the surgical methods and clinical applications of single operation hole for thorascopic surgery in treatment of encapsulated effusion with atelectasis after thoracic injury.Methods From October 2011 to October 2013,using single operation hole for thorascopic surgery treating encapsulated effusion with atelectasis in 56 cases after thoracic injury,35 males and 21 females,aged 21-68,mean 34 years old.The left encapsulated effusion with atelectasis in 31 cases,the right of encapsulated effusion with atelectasis in 25 cases,atelectasis in 43 cases,partial atelectasis in 9 cases,total atelectasis in 4 cases.Before thorascopic surgery,routine thoracentesis or (and) closed thoracic drainage were performed,but ineffective.Surgical approach for anesthesia with the thorascopic surgery encapsulated effusion dissection + suction drum lung surgery.Thorascopic surgery were completed in single operation hole,postoperative chest tube into the hole from observation.Results The operation time was 55-120 min,average 75 min; blood loss was 25-150 ml,average 65 ml.All patients underwent in single operation hole.The postoperative hospital stay was 7-19 d,average 11.2 d.There were no perioperative mortality and major complications.Conclusions The single operation hole for thorascopic surgery in treatment of encapsulated effusion with atelectasis after thoracic injury is exactly effective and simple.It can be used as an effective treatment.

Objective To characterize differences within facial profile esthetic evaluations among three groups of evaluators and the influences of sagittal or vertical skeletal patterns on facial profile esthetics. Methods A total of 114 silhouettes,from the pre?or post?treatment facial profiles of 57 patients,were scored by three groups of evaluators(professionals,patients'parents,and laypersons)to characterize differences within facial es?thetics evaluation among evaluators. The highest?scoring 30 silhouettes and the lowest?scoring 30 silhouettes were selected as the high score group and the low score group,respectively. Sixteen indices of the relative lateral cephalometric films were measured. Data were analyzed by SPSS 21.0. Results Facial profiles following orthodontic treatment scored higher than pre?treatment(P<0.05). There were significant differences between professionals and laypersons in facial profile scoring. Different sagittal skeletal patterns had no effect on esthetic evaluation ,but lower facial height significantly influenced whether a patient received a high or low esthetic score(P<0.05). Conclusion Orthodontic treatment can improve the fa?cial profile significantly,and lower facial height is the most sensitive index for facial profile evaluation in our study. However,all three evaluator groups have different esthetic standards that don't overlap. Notably,the expectations of laymen are higher than those of orthodontists.

Objective Explore the individual difference in carbon monoxide (CO) poisoning and analyze whether females were be more resistant to CO poisoning.Methods We collected 207 cases of CO poisoning deaths, and then we analyzed the Carbonyl Hemoglobin (COHb) results sorted by different sources of CO.Results The source of CO had significant impact on the fatal COHb level, but gender was not significant in affecting COHb level. In addition, it is possible that children and elders were less resistant to COHb than adults.

OBJECTIVE To investigate the distribution and drug resistance of nosocomial infection pathogens.METHODS The data of pathogen′s origin and antibacterial resistance of Intensive Care Unit(ICU) inpatients from Apr 2008 to Mar 2009 in a Hospital were analyzed.RESULTS There were 226 strains pathogens isolated from 116 nosocomial infection cases,from which the Gram-negative bacteria were predominate(63.27%).The resistance rates of Acinetobacter baumannii was the highest in Gram-negative bacteria,more than 70% isolates resistant to almost antibacterial.The main Gram-positive bacteria were Staphylococcus aureus,and the rate of meticillin-resistant S.aureus(MRSA) was 41.3%.All S.aureus were sensitive to vancomycin and Linezolid.CONCLUSIONS To control the antibacterial resistance of pathogens and decrease the nosocomial infection,it is important to strengthen the appropriate use of antibiotics.

OBJECTIVE To investigate a case of nosocomial infection incident in a hospital,analyze the reasons and put forward preventive measures.METHODS Investigation was carried out on the related people and environment in the department where the incident occurred.Analysis was made on the reasons and processing.RESULTS The nosocomial infection incident was caused by Norovirus;fecal-oral transmission and contact transmission were 2 main pathways of Norovirus.There were 7 persons who had been contaminated by Norovirus,included 5 old inpatients,1 doctor and 1 nurse.CONCLUSIONS Many people should work to prevent and control the infections in hospital,such as doctors,nurses,inpatients,hospital works etc.Hand-washing and disinfection isolation should be enhanced among the hospital staffs in the normal works.

YKL-40 (human cartilage glycoprotein 39) is a newly discovered inflammatory cytokine, which belongs to the member of 18 glycosyl hydrolase of mammal family. Previous studies have indicated that YKL-40 is associated with the acute or chronic inflammatory diseases and tumors. Studies in recent years have suggested that YKL-40 may be involved in the occurrence and development of atherosclerotic plaques, and it is correlated with the plaque instability. The physiological function and the mechanisms of YKL-40 are not fully understood. It may have the roes of promoting vascular smooth muscle migration and proliferation, promoting cell adhesion and proliferation, as well as regulating extracellular matrix remodeling The detection of YKL-40 may have some significance in the aided diagnosis, predicting prognosis, prevention of cardiocerebrovascular diseases, and even the establishment of new therapeutic strategies.

Tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) can be induced in ischemia and other pathological states and mediate neuronal apoptosis after cerebral ischemia.Understanding the upregulation mechanism of TRAIL in ischemic brain tissue is promising to develop new treatment for stroke.

Objective This study compared the cleaning effect of gastroscope by different cleaning mehtods and discuss practical and reliable evaluation method for the cleaning degree of gastroscope.Methods Three cleaning methods were selected and used in the cleaning of gastroscope.The Endocheck lumen was used to examine the cleaning degree of gastroscope and the effects of different methods were compared. Results The qualification rate by using ordinary cleaning method was 50.0%and it reached 60.0%and 73.3%by elevation of polyenzyme concentration and adding bedside pre-washing.which Was statistically different from that by using ordinary cleaning method(P＜0.05).Conclusions Bedside pre-washing could increase the cleaning degree of gastroscope;Endocheck lumen could be regarded as an evaluation method for the cleaning degree of gastroscope.

Objective To explore the effect of comprehensive intervention measure on antimicrobial use and incidence of healthcare-associated infection(HAI)in patients in sports medicine department.Methods Antimicrobial use and incidence of HAI in hospitalized patients in the surgical departments (sports medicine department and other surgical departments)of a hospital between January 2006 and December 2010 were analyzed retrospectively(before intervention),from January 2011, comprehensive intervention based on clinical-centered multi-department cooperation was adopted by sports medicine depart-ment,the other surgical departments over the same period were not comprehensively intervened;antimicrobial use and inci-dence of HAI in patients in surgical departments between January 2012 and December 2013 were monitored prospectively (after intervention ),effectiveness of intervention was evaluated.Results Antimicrobial use and incidence of HAI in pa-tients in sports medicine department after intervention were both lower than before intervention (55.75% vs 95.26%,χ2=753.42;0.10% vs 0.32% ,χ2 =15.13,both P <0.01).Antimicrobial use in patients in other surgical departments after intervention was lower than that before intervention(65.63% vs 73.79% ,χ2 =251.57,P <0.01 );incidence of HAI was higher than that before intervention(0.55% vs 0.42% ,χ2 =19.04,P <0.01).Conclusion Comprehensive in-tervention measure based on clinical-centered multi-department cooperation is safe and effective,it can reduce antimicrobial use and incidence of HAI in patients in sports medicine department.
