Objective Statistics and analyze the effect of comprehensive prevention measures for the ventilator associated pneumonia (VAP) morbidity and mortality,and investigate its actual applicate situation in the clinical.Methods Statistics and analyze the clinical date of 183 cases of our ICU mechanical ventilation patients in 2012 (group A),including morbidity,mortality,time of endotracheal intubation,length of stay and the primary pathogenic bacteria,and to compared with the relevant clinical data of 192 cases of our ICU mechanical ventilation patients in 2011 (group B),summarize and analysis the actual applicate situation of the comprehensive prevention measures in the clinical through the data contrast.Results The incidence of VAP in group A was lower than that in group B [31.7％(58/183) vs.58.3％(112/192)] (P ＜ 0.05),but the mortality was no statistical difference in both groups (P ＞ 0.05) ; the endotracheal intubation time and the average length of stay in group A were less than those in group B [6.3 d vs.10.6 d,7.6 d vs.11.9 d](P＜0.05); the main pathogenic bacterium of VAP with mainly gram-negative bacilh.Conclusions Comprehensive prevention measures can effectively reduce the incidence of VAP,but the mortality rate has no significant effect,need further clinical research;comprehensive prevention measures to reduce patients with tube time also confirm its effectiveness.Comprehensive prevention measures are economical and practical,is worth in clinical promotion.

It is common in bacterial genomes of the integration of prophages. As an important participant of the vital movement of their hosts, prophages affect closely the biological properties of the hosts. Therefore, if we want to comprehend a bacterial genome fully, it is essential to recognize and understand accurately prophages in it. This article is a compendious review about the classification, distribution, identification, evolution of prophages and the interaction with their hosts.

Objective To compare the effect of enteral administration and intravenous infusion of hypertonic electrolyte glucose solution (HEGS) in the resuscitation of burn shock. Methods Fifteen beagle dogs with 35% TBSA third degree burn were used in present study, and divided into three groups randomly: noresuscitation group, intravenous infusion resuscitation group and enteral administration resuscitation group. For the animals in the latter two groups, 1.8% HEGS was administrated intravenously or enterally for resuscitation 30 min after burn. The volume of fluid infusion in the first 8h was 1ml/(kg?1% TBSA), and the transfusion velocity was equilibrated. The mean arterial pressure (MAP), cardiac index (CI), plasma volume (PV), and sodium concentration in plasma were obtained to evaluate the effect of resuscitation used HEGS. Results The MAP, CI and PV were similar in both enteral and intravenous groups, which were higher than those in noresuscitation group. In both enteral and intravenous groups, MAP was raised after burn and then lowered after resuscitation, meanwhile CI and PV were raised and then lowered after resuscitation, but there were no differences between the two groups. The sodium concentration in plasma was stable in the noresuscitation group and increased in enteral and intravenous groups, and it was higher in intravenous groups than in enteral group. Conclusion In the resuscitation of early shock of 35% TBSA three degree burns, the effect of 1.8% HEGS administrated enterally on CI, PV, MAP and sodium concentration in plasma was similar to that of intravenous infused.

Rheological properties of poloxamer 407 (brand named Pluronic F127) were examined by changing shear rate, temperature and the recovery properties of apparent viscosity after heating for several times. The results indicated that poloxamer 407 aqueous solution showed a Newtonian behavior at a low concentration while it might be a pseudoplastic fluid when the concentration reached a certain point. The thixotropy and the sol-gel transition temperature decreased with increasing the concentration (it could be an in situ gel at body temperature when the concentration of poloxamer 407 up to 15.25%). The results that obtained from the theological data would be useful in the application of poloxamer 407 such as in situ gel preparation.

Objective To evaluate the application of ZEEK thrombus aspiration catheter in treatment of acute myocardial infarction (AMI) in elderly patients. Methods The 52 patients with ST-elevation myocardial infarction(STEMI)were treated with percutaneous coronary intervention (PCI) plus thrombus aspiration by using ZEEK thrombus aspiration catheter (ZEEK group), and 42 STEMI patients were treated only with PCI (control group). The regression rate of ST segment, left ventricular ejection fraction (LVEF), incidence of no-reflow and mortality were followed up after PCI during hospitalization. Results No-reflow occurred in 5 (11.9%) patients and 1 (1.9 %) patient in the control group and ZEEK group, respectively. And 2 deaths were encountered only in the control group. The differences between the two groups were statistically significant (P＜0.05).Conclusions AMI treatments with PCI and application of ZEEK aspiration thrombus catheter are safe and effective. The two methods could lower thrombosis burden, may improve distal myocardium perfusion and cardiac function after the procedure.

With the advances in techniques of localization, numerous minimally invasive parathyroid surgery were developed including open minimal incision and endoscopic approaches. According to the research results and the experiences from Peking Union Medical College Hospital, the indication and preoperative preparation were discussed in this paper. Some suggestions were given for minimally invasive parathyroid surgery in China.

OBJECTIVE: To develop a network management system needed by infusion drugs’ disposition center in hospital. METHODS: Based on “Army No. 1” hospital Information, the infusion drugs’ disposition management system was studied and developed by applying PowerBuilder 6.5 and barcode management. RESULTS: The infusion drugs’ disposition management system consisted of 2 subsystems, which have the function of printing and identifying bar code labels, automatic checking infusion drug prescriptions, conducting information exchange within the local area network and improving management efficiency of infusion drugs’ disposition and meanwhile improving drug quality. CONCLUSION: Fully understanding and optimization of the business flow-sheet are keys in the successful development and application of infusion drugs’ management system. To improve the management level, the application of new technology is essential.

[Objective] To observe the effect of medical ozone on cartilage in the model of osteoarthritis(OA)to explore its therapeutic mechanism.[Method] Forty healthy adult SD rats were randomly divided into five groups :A(group normal)、B(group model)、C(group air),D(group O2~O3 35 ?g/ml)and E(group O2~O3 70 ?g/ml)(n=8 in each group).The OA model was duplicated by performed anterior eruciate ligament transection(ACLT)and partial meniscectomy of 1/3 inside.Air was injected into joints of group C,according to concentration different,which O2~O3 35 ?g/ml and O2~O3 70 ?g/ml were respectively injected into joints to D and E group every other day,every time 1～1.5 ml,and after a week injected again.After the model was successfully made,the condylar cartilage of femur was excised after 4 weeks for the observation by transmissive microscope of HE staining.Mankin's index was recorded.At the end of the experiment,douche fluid of the diseased joints were obtained for the measurements of superoxide dismutase(SOD)and malondialdehyde(MDA).[Result]The OA model in B group founded obviously degenerative changes under microscopy,resulting in mostly blue and green color destaining of Masson staining at superficial cartilage.The activity of SOD in the douche fluid of the diseased joints degraded and the quantity of MDA in the serum in the OA model group increased.The Mankin's index in the group D was significantly higher than that in the group B、 C(P
