Objective:To explore influence of preoperative tirofiban usage and using time on blood flow of infarct re-lated artery (IRA) in patients with acute ST elevation myocardial infarction (ASTEMI ) undergoing emergency di-rect percutaneous coronary intervention (PCI ) .Methods:A total of 266 ASTEMI patients undergoing direct PCI from Jan 2009 to Oct 2012 ,were randomly divided into tirofiban group (n=134 ,received preoperative tirofiban us-age for PCI) and routine treatment group (n=132 ,didn't receive tirofiban during PCI) .According to percutaneous using time of tirofiban tirofiban group was divided into <3h group (n= 63) and ≥3h group (n= 71) ;TIMI blood flow of IRA ,before and after PCI were compared among different groups .Results:Compared with routine treat-ment group before PCI ,there were significant rise in percentages of TIMI grade 3 (10.6% vs .20.9% ) in tirofiban group ,P=0.028 ;after PCI ,percentage of TIMI grade 3 in tirofiban group was more significantly rose than that of routine treatment group (78.8% vs .92.5% ,P=0.001);in tirofiban group ,blood flow of IRA before PCI in <3h group was significantly improved compared with ≥3h group (TIMI grade 2 + 3 ,63.5% vs .29.6% , P<0.01) . Conclusion:Early tirofiban usage can improve TIMI blood flow of IRA before and after PCI in ASTEMI patients , the earlier it′s used ,the more significant effect it has .

Aim To determine TAT-Tcntf penetration ability and to investigate the effects of the fusion protein on SH-SY5Y cells against toxicity induced by β-amyloid peptide 25-35(Aβ_(25-35) ).Methods The conjugate(TAT-tCNTF)of TAT(47-57)of HIV-1 and the truncated human CNTF active fragment was genetic engineered and expressed in E.Coli.Immunofluorescence was used to identify cell permeation ability across membrane.MTT assay was used to measure the survival of SH-SY5Y cells injured by Aβ_(25-35).And Hoechst 33342/PI double staining was used to observe the morphology of cell apoptosis and necrosis.LDH was measured by spectrophotometric method.Results The expression vector of pBV220-TAT-tCNTF was constructed successfully.Western blot showed the recombinant fusion protein could bind specifically with CNTF antibody.The immunofluorescence assay clearly demonstrated that TAT-tCNTF did penatrate into the cells while little rhCNTF pass across the cells.Double staining and LDH release assay demonstrated that TAT-tCNTF could promote significantly the survival of the cells.Conclusion sTAT-tCNTF with high activities and effective transmembrane ability is obtained for the first time.The fusion protein protects SH-SY5Y cells from death after Aβ25-35 exposure.

Objective To improve the detail of the surgery for cicatricial ectropion,and the the effect was investigated. Methods Based on 46 patients withⅡ,Ⅲdegree cicatricial ectropion admitted to our department,choose the junction of normal skin and scar tissue as the incision line according to the degree of ectropion and local situation,and to reserve and recover the orbicularis oculi muscle as possible. The released areas exceeded separately the external canthus and reached the level of eye fissure,take advantage of full-thickness skin graft to correct the parallel lines and make fixation to the eyelid ectropion fusion skin graft on external canthal ligament. Results After followed up for 6 months to 2 years,46 cases of eyelid skin grafts survived completely and eyelids were in good reduction,with none case of incomplete eyelid closure. Conclusion Choose the surgical incision and the released areas in a proper way to reserve the structural integrity of orbicu-laris muscle and make skin graft fixation to inner and external canthal skin can prevent effectively the recurrence of ectropion and improve surgical progress.

Objective To explore the efficiency of continuous glucose monitoring system(CGMS) and blood glucose self-monitoring (SMBG)in evaluating blood glucose excursion in type 1 diabetes mellitus (T1DM) complicated with pregnancy. Methods Twenty-five patients having suffered from T1DM complicated with pregnancy were selected randomly during June 2012 to July 2015. All subjects underwent blood glucose monitoring by CGMS and SMBG for 72 h, including the data of blood glucose before meal, 2 h post-meal blood glucose (2hBG) and blood glucose at 2:00 AM. Results The level of the highest blood glucose in CGMS was significantly higher than that in SMBG:(10.60 ± 2.11) mmol/L vs. (7.50 ± 1.18) mmol/L, P<0.01. The level of the lowest blood glucose in CGMS was significantly lower than that in SMBG:(3.60 ± 1.06) mmol/L vs. (4.50 ± 1.15) mmol/L, P<0.01. The level of mean blood glucose in CGMS and SMBG had no significant difference:(7.20 ± 1.18) mmol/L vs. (7.30 ± 1.15) mmol/L, P>0.05. The rate of hypoglycemia(blood glucose<3.3 mmol/L) in CGMS was 4.6%, and in SMBG was 1.9%. Through adjusting the treatment by CGMS, the blood glucose before meal, 2hBG and blood glucose at 2:00 AM at 49-72 h were significantly lower than that at 0-24 h (P<0.05). Conclusions Compared with SMBG, CGMS has a relatively larger blood glucose monitoring range and can sensitively evaluate blood glucose excursion, CGMS provides a scientific basis to develop a more rational and effective strategies for controlling diabetes.
