Objective To investigate the hemostatic effect of the radial hemostatic compression device(TR Band hemostatic gasbag)after transradial coronary intervention and discuss the optimal hemostasis time.Methods 266 patients who received transradial coronary angiography and used TR Band hemostatic gasbag for hemostasis were divided into group A,B and C,according to the compression time,the compression time in group A (90 cases)was 8 h,10 h in group B (87cases),12 h in group C (89 cases).The condition of bleeding,changes in blood oxygen saturation,and hand swelling in each group were compared.Results The bleeding rates of group A,B and C were respectively 16.7％,3.4％ and 9.0％,the difference was statistically significant.The incidence of hand swelling after operation in group A,B and C were respectively 27.8％,12.6％ and 21.3％,the difference was statistically significant.No significant difference was seen in blood oxygen saturation between three groups.Conclusions Application of radial hemostatic compression device after transradial coronary intervention proved good hemostasis effect,compression time for 10 h has the best effect and less adverse effect.

Objective To investigate the advantage and safety of the concept of fast-track surgery (FTS)applied in perioperative patients with biliary calculi and liver cirrhosis.Methods Fifty-two patients undergoing operation for biliary calculi and liver cirrhosis from January 2011 to September 2013 were included in this study.These patients were randomly divided into FTS group (n =30)and control group (n =22).Patients in the FTS group received perioperative care measures guided by FTS concept,while patients in the control group re-ceived traditional perioperative management measures.The intraoperative situation of patients,time to postoperative recovery of intestinal function,length of postoperative hospital stay,total medical expenses during hospitalization,and postoperative complications were compared between the two groups.Continuous data and categorical data were compared by t-test and χ2 test,respectively.Results As compared with the control group,the FTS group had significantly time to postoperative recovery of intestinal function (t =2.239,P =0.045),a significantly shortened length of postoperative stay (t =4.246,P =0.038),and significantly reduced total medical expenses during hos-pitalization (t =3.045,P =0.033).No significant difference in postoperative complications was observed between the two groups (P>0.05).Conclusion The concept of FTS can be safely and effectively applied in perioperative patients with biliary calculi and liver cirrho-sis,which can accelerate rehabilitation without increasing the risk of surgery.

0.05). Conclusion Mb-MGM have good properties of drug-targeting and sustained drug releasing properties. Mb-MGM could be used for targeting spinal cord dorsal ganglia for nerve blocking after being injected into the subarachnoid space and under effect of magnet. The motor function is not affected.

[Objective] To observe the effect of Leweiyin of traditional Chinese compounds prescription on gastrointestinal hormones and oxygen free radicals in IBS rabbits of spleen deficiency,and to explore the possible mechanism for the treatment of IBS with spleen deficiency.[Methods] 36 two-month-old rabbits with white feather and black eyes(WHBE rabbit),half male and half female,were randomly divided into 6 groups:normal group,model group,Xiangsha Liujun pill group,Lizhu Changle group,low-dose Leweiyin-treated group,high-dose Leweiyin-treated group.Except the normal group,others were made into IBS model of spleen deficiency which was induced by damp heat stress and gavage with Fanxieye as well as method of either hunger or gorge.The drug groups were administered preventively from the medium-term of the model reproduction to the end of modeling.The rabbits of each group were observed.NO,NOS,MDA,SOD in serum and SP in colonic membrane were detected.[Results] NO,NOS,MDA in serum and SP in colonic membrane significantly more increased than the normal group(P

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.

Objective To explore the significance and important measure of integrative treatment of multiple trauma patients with severe craniocerebral injury in emergency center. Methods One hundred and forty-eight multiple trauma patients with severe craniocerebral injury in emergency center from November 2002 to February 2006 were analysed retrospectively. Result In total 148 cases, 72 were cured and 26 dead, 7 were in status of plant man, 17 experienced severe deformity, and 26 did mild deformity. Conclusion Multiple trauma patients with severe craniocerebral injury usually experience a serious situation and rapid development. Therefore emergency doctors are required for organizing salvage of such patients, at the same time treatment and diagnosis are implemented. Firstly the most important key to successful salvage is appropriate disposal of fatal injury and early elimination of shock. Proper surgical choice, especially at the first time, inspection and protection of visceral functions, and attention to nutritional support are other vital methods to gain more successful salvage. ICU is also emphasized for its essentiality.

OBJECTIVE:To observe the curative effects of compound glycyrrhizin injection in treatment of primary sjogren syndrome(PSS).METHODS:68 patients with PSS were randomized into the treatment group and control group,and treated for 4wk with hydroxypiperaquine,bromhexine and carmellose.The treatment group also received compound glycyrrhizin injection in addition to the three agents for the control group.RESULTS:After treatment for 4wk,both groups saw some declines in IgG,IgM,IgA,ESR and RF,and improvement in indicators such as schemer test and saliva flow rate,with the treatment group showing more significant improvement than the control group(P

OBJECTIVE: To study the curative effect of Sodium Ferulate( SF) on rheumatoid arthritis( RA) and its effects on the levels of serum vascular endothelial growth factor( VEGF) and tumor necrosis factor- ? ( TNF- ? ) . METHODS: A total of 43 patients with RA were randomly divided into trial group and the control group: conventional treatment was adopted in both groups, but the trial group was treated additionally with SF injection for 4 consecutive weeks. Serum levels of VEGF and TNF- ? before and after treatment were determined by the enzyme linked immunosorbent assay( ELISA) . RESULTS: The total effective rate in the trial group the control group were 91. 30% vs. 75. 00% ( P
