This paper mainly studies the driving system of centrifugal blood pump for extracorporeal circulation, with the core being disc magnetic coupling. Structure parameters of disc magnetic coupling are related to the ability of transferring magnetic torque. Therefore, it is necessary to carry out disc magnetic coupling permanent magnet pole number (n), air gap length (L(g)), permanent magnet thickness (L(m)), permanent magnet body inside diameter (R(i)) and outside diameter (R(o)), etc. thoroughly. This paper adopts the three-dimensional static magnetic field edge element method of Ansys for numerical calculation, and analyses the relations of magnetic coupling each parameter to transmission magnetic torque. It provides a good theory basis and calculation method for further optimization of the disc magnetic coupling.

Background Bevacizumab and triamcinolone acetonide (TA) has been widely used in the treatment of diabetic macular edema (DME) clinically,but the effectiveness of both treatment has disadvantage.Therefore,some researchers try to combine bevacizumab with TA for the management of DME,but its efficacy is controversial.Objective This study was to evaluate the efficacy and safety of intraovitreal injection of bevacizumab combined with TA versus bevacizumab for DME.Methods The randomized controlled trials (RCTs) of bevacizumab combined with TA versus bevacizumab via intraovitreal injection for DME were searched from Pubmed,EMbase,Cochrane Library,CNKI.The methodological quality of the literature was evaluated according to evidencebased medicine (EBM),and the quality of the RCTs was appraised based on the Cochrane Handbook for Systematic Reviews of Interventions Version 5.0.The outcome indicators including the change values of central macular thickness (CMT) and best-corrected visual acuity (BCVA) as well as the safety indicators including topical and system adverse response of RCTs were analyzed with Cochrane Collaboration' s software RevMan 5.0.Results Nine RCTs were included with 665 eyes.The decrease value of CMT was more remarkable in the bevacizumab combined with TA group than that of the only bevacizumab group 12 weeks and 18 weeks after intravitreal injection (WMD =-44.69,95％ CI:25.27-64.11,P ＜ 0.000 001 ; WMD =-66.86,95％ CI:40.67-93.05,P ＜ 0.000 001).However,no significant differences were found in the change value of CMT in 6 weeks and 6 months after injection between the two groups (WMD =-15.40,95％ CI:-4.04-34.85,P =0.12 ; WMD =-2.57,95％ CI:-19.62-24.75,P =0.82).The improvement value of BCVA (LogMAR) in the bevacizumab combined with TA group was superior to that of the only bevacizumab group 6 weeks after injection (WMD =-0.04,95 ％ CI:-0.08--0.00,P =0.05),but there were no significant differences between the two groups at 12weeks,18 weeks and 6 months after treatment (WMD =-0.04,95％ CI:-0.12-0.05,P=0.36;WMD =-0.04,95％ CI:-0.11-0.03,P=0.28; WMD =0.03,95％ CI:-0.05-0.12,P=0.45).The incidence rate of transient anterior response after injection was not significantly different between the two groups (RR =0.89,95％ CI:0.49-1.60,P =0.70).Secondary ocular hypertension after injection occurred in 30 eyes in the bevacizumab combined with TA group,but no hypertension was seen in the only bevacizumab group.Conclusions Compared with only bevacizumab,intravitreal injection of bevacizumab combined with TA has a better efficacy in improving CMT but no obvious dominant in increasing BCVA for early DME.Intravitreal injection of bevacizumab combined with TA seemingly has a higher risk of inducing controllable ocular hypertension than administration of only bevacizumab.

The main causes of early mortality after the earthquake are traumatic shock, hemorrhage and dehydration, and the ratios of shock and hemorrhage are high in patients with abdominal injuries. Prompt triage is very important to persons with abdominal injuries who were rescued in 48 hours after the earthquake. Primary triage should be carried out in the rescue field, and then followed by the secondary triage in the hospital. We improved the efficiency and accuracy of triage by following the principle of "5 steps, 3 categories and 1 indication". Nineteen persons with identified abdominal injuries and unstable vital signs received operation. The false positive rate was 5% (1/19), and the successful rate of the operation was 95% (18/19). During the process of rescue, the lives of the injured persons should be put in the first place. The operation should be performed under the principle of simpleness, rapidity and safeness.

Objective To obtain the specific human scFv basic fibroblast growth factor(bFGF)using phage antibody library technology. Methods The library was panned with human recombinant bFGF for 4 rounds. The antigen binding activities of random clones were tested by ELISA in order to select specific antibodies, which were then examined by DNA sequence analysis. Results The positive clone selected from the 104 random clones was able to bind bFGF specifically, while not able to bind other growth factors,such as aFGF, VEGF(vascular endothelial growth factor). By competition ELISA assay we found one clone 44 could inhibit bFGF binding to FGFR1. Conclusion Seven specific human phage antibody against bFGF was obtained by phage display technique, one clone could inhibit bFGF binding to its high affinity receptor FGFR1.

Objective To explore a new method of parapancreatic abscess treatment and establish an idea of minimally invasive technologies for parapancreatic abscess to improve the recovery rate of acute pancreatitis. Methods The patients had experienced percutaneous puncture and placed drainage tube under the ultrasound guidance first, then the sinus tract was expanded gradually to 24F perimeter by Cook's fascia expender. Finally, the necrotic tissue and pyogenic membrane was removed and repeatedly washed under guidance of choledochoscopy. Results The recovery rate was 91.1 %(33/36). The complication incidence was 10.7% (hemorrage:2 cases, external intestinal fistula:3 cases, and fatal MOF: 1 case). Conclusions The viewpoint which parapancreatic abscess only can be cured by drainage operation can be changed by associating debridement by choledochoscope with percutaneous puncture drainage under the ultrasound guidance. It is a simple, safe and effective method. It can be used to reduce the patients' damage, complication and mortality and accomplish the idea of damage control by minimally invasive technologies.

Objective To explore the clinical efficacy of proximal femoral locking compression plate (LCP)fixation in elderly intertrochanteric fractures patients. Methods 30 cases of intertrochanteric fracture fixed with LCP were collected,and the functional recovery of all hip joints was observed.
