For the diathermancy of the seawater is much bigger than that of the air, and the heat dispersed from the body exceeds the heat produced by the body, the heat would be lost immediately when people fell into the cold seawater. The temperature of people would drop instantly to frozen stiff. So it has great signification to rescue the people dropped into the cold water at once. This paper will introduce how to rescue, examine, stabilize, insulate, finally transport the patient to the hospital, and some things that should be paid attention to during the whole process.

Objective To explore the relations between UA and serum hs-CRP, the effects of early intervention with atovastatin on serum hs-CRP in patients with UA and its clinical significance in the early management of UA. Methods T 60 patients with UA (UA group),53 patients with stable angina (SA group) and 50 healthy controls (control group) were enrolled to the study. The serum hs-CRP levels were measured by particle enhanced immunoturbidimetric assay. UA group were randomly assigned to the atovastatin group and the routine group for a 4-week treatment immediately after admission. Selected coronary artery angiography was performed in 78 patients and 29 healthy controls with Judkin's technique. Results Baseline of hs-CRP in patients with UA was significantly higher than those in SA group and control group ( P

were obviously increased. Conclusion HIF-1α was successfully cloned. HIF-1α-pcDNA3.1 can be effectively transfected into MSCs with liposome-mediated method, which can result stable expression of HIF-1αin transfected MSCs.

Objective To investigate the effect of ulinastatin (UTI) on the expression of brainderived neurotrophic factor ( BDNF ) and remyelination in mice with experimental autoimmune encephalomyelitis ( EAE).Methods Twenty-four C57BL/6 mice were randomly divided into UTI group (U),normal saline treated group (S) and normal control group (N,n = 8,respectively).Demyelinations in the spinal cord were observed by solochrome cyanin staining.The expression of BDNF,myelin basic protein (MBP),and 2',3 '-cyclic nucleotide 3'-phosphodiesterase (CNP) in brain tissue of each group were evaluated by Western blot.Results Average clinical scores in group U at the 12,13,14,22,23,31,33,34 and 35 days were 0,0.25,0.38,0.63,0.63,0.40,0.40,0.40 and 0.40 respectively.They were significantly lower than group S at the same time ( U= 16.00,15.00,14.50,7.50,0.00,14.50,14.50,12.00 and 14.50,all P ＜0.05).Solochrome cyanin staining showed that demyelination of spinal cord in group U was also significantly improved than group S.Expressions of BDNF ( 1.96 ± 0.29),MBP (2.67 ± 0.48 ) and CNP ( 1.75 ± 0.20) in group U were all significantly higher than group S ( There were 0.80 ± 0.15,1.36 ± 0.38 and 1.06 ± 0.18 respectively,all P ＜ 0.05).Conclusions UTI has protective effect on EAE.The possible mechanism is that it could promote remyelination,and protect oligodendrocytes and neurons in EAE model by increasing BDNF expression in brain.

Objective To explore effects of doctor-nurse integrated care management model on fast track (FT) perioperative management of colorectal cancer patients.Methods Between January 2014 and September 2014,112 colorectal cancer patients (innovation group) underwent doctor-nurse integrated care and FT management in West China Hospital were analyzed retrospectively;who were compared with 96 patients (control group) underwent FT management from the same period of 2011.Early postoperative rehabilitation indicators,length of hospital stay,30d readmission rates,total hospitalization costs and patients satisfaction were compared.Results Innovation group of patients for the first time of post-operative flatus,defecation,oral feeding,ambulation,gastric and drainage tubes removal time were all earlier than those in control group,P ＜0.05,while the difference of urinary catheter tube removal time between the two groups was not statistically significant,P ＞ 0.05;the length of hospital stay in innovation group(6.05±2.05) d was significantly shorter than that in control group (7.85±3.22) d,P ＜ 0.05;preoperative hospital stay in innovation group was (1.35±0.45) d,shorter than that in control group (2.56±0.63)d,P ＜ 0.05;the patients satisfaction points in innovation group was (94.t2±3.12) points,which was higher than that in control group (86.36±5.51) points,t=2.589,P ＜0.05.Conclusion Doctor-nurse integrated care management model can improve postoperative rehabilitation effects,can reduce average hospital stay,total hospitalization costs and improve patients satisfaction.

Objective To summarize the clinical treatment experience of blood culture-negative infective endocarditis,and to explore the surgery chance and therapeutic strategy of blood culture-negative endocarditis. Methods One hundred and sixty-six patients who were diagnosed blood culture-negative endocarditis in the Aisa Heart Hospital of Wuhan from Jul. 2008 to Dec. 2012 were recruited in the study. Broad-spectrum antibiotics including cefuroxime axetil and levofloxacin were used before the result of blood culture,and sensitive antibiotics were selected to control patient's condition when getting the result of blood culture. But broad-spectrum antibiotics were continuously used to the blood culture-negative endocarditis until stable condition. When the conditions were stable,active preparation before surgery should be carried out. Thoroughly clear the vegetation and protect the cardiorespiratory function during operating. Kata-step antibiotics were used to control patient's condition until normal temperature,as well as the number of leukocytes decreased,blood sedimentation normalized and C-reaction protein decreased. Then,the narrow-spectrum antibiotics were selected including cephalosporin until discharged from hospital,and continued treatment of antibiotics for 4 - 6 weeks. Results Five patients died after the operation,including 1 case died of low cardiac output syndrome,2 cases died of multiple organ failure,1 case died of septicemia and the 1 case died of cerebral embolism. All the other patients discharged from hospital successfully. Conclusion The patients with blood culture-negative IE should be controlled rapidly. The duration and dose of antibiotics should be enough. Active operative preparation should be taken and then surgery timely. Thus,the hospital mortality could decrease and prompt the long-term outcome.

This paper investigated contamination situation of Listeria monocytogenes(Lm). To compare dif- ferent selectivity enrichment broth for detectable effect of Lm and compare detectable effect in different samples by using different methods, furthermore, choose the best enrichment broth for specific food. One hundred and thirty five random samples from raw meat, aquatic product, fruit and vegetable, quick-frozen food in Baoding. Applied LB enrichment broth, EB enrichment broth, new modification FDA enrichment broth and Fraser enrichment broth before separated by PALCAM selective agar, then identified by interna- tional standard method after PCR. Results: Four methods showed that there were 23 Lm positive, detected 5 Lm by LB method, 6 Lm by Fraser method, 5 Lm by EB method and 7 Lm by new modification FDA method. The total detectable rate of four methods had no large specificity, but to specific kind of food was different.
