Objective: To explore the clinical efficacy of a new drug for acute coronary syndrome (ACS), ticagrelor in treating the patients with acute ST-segment elevation myocardial infarction (STEMI), and to compare the effect between ticagrelor and clopidogrel in order to obtain the prospective information of ticagrelor in clinical practice.
Methods: A total of 307 STEMI patients were divided into 2 groups, Treatment group, the patients received ticagrelor with aspirin, n=157 and Control group, the patients received clopidogrel with aspirin, n=150. With a period of treatment, the major adverse cardiac events (MACE), rate of thrombosis re-formation and routine blood test result were compared between 2 groups.
Results: Treatment group presented the better LVDD, LVEF, platelet level and ST-segment recovery than those in Control group, P<0.05 or P<0.01. Treatment group showed slightly higher rate of side effect such as dififcult breathing and bleeding, while those reaction did not affect the treatment or special management for the patients.
Conclusion: The clinical effect of ticagrelor is similar to clopidogre for improving the platelet level and cardiac function in STEMI patients, while the clinical advantage reported in abroad should be further studied.

Objective To evaluate the safety,biocompatibility and efficacy of transcatheter closure of atrial septal defect(ASD)with no stainless-steel-screw occluder in canine model.Methods The device was constructed from superelastic Nitinol wires tightly woven into two flat disks and sewed with polyester fibers inside,with a pliable loop on the right-atrial-disk of the device,connecting to the delivery cable.ASD was created by transcatheter puncture and balloon dilatation and then closed by occluder under fluoroscopy in the catheterization laboratory.The location and the influence of the implanted device on function of tricuspid valve and mitral valve were evaluated by echocardiography.At 1,2,3 and 6 months after the operation,the animals were killed and autopsy was conducted.Results Eight dogs with puncture-produced ASD underwent ASD closing procedure successfully.The occluder showed no influence on the function of MV and AV demonstrated by echocardiogram.The two disks of the implanted device were covered with a smooth intact neogenesis layer in all dogs.Endocardial cells fully covered the surface of the two disk without inflammating reaction 3 months later. There was no evidence of corrosion on the surface of the nitinol wire removed from the dog after 6 months.Light microscopic examination of the liver,kidney,lung and spleen showed no evidence of embolization and inflammation.Conclusion Transcatheter ASD occlusion with new-type occluder is safe,feasible,effective and good biocompatibility with a good prospective clinical application.

Objective To explore the correlative factors and management of secondary high intraocular pressure(IOP) after vitreoretinal surgery for proliferative diabetic retinopathy(PDR). Methods The data of 51 patients(54 eyes) with PDR after vitreoretinal surgery were collected.The incidence of secondary high IOP was obtained,and the correlative factors leading to high IOP were analysed.Besides,the therapeutic effects of management were observed. Results Twenty-six patients(26 eyes) experienced postoperative high IOP,with the incidence of 48.15%(26/54).It was revealed that the preoperative retinal detachment,the combined performance of crystal phacoemulsification,the practice of intraocular tamponade and the postoperative posterioruveitis were related to the occurrence of high IOP(P

OBJECTIVE: To evaluate the effect of Xiangdan Injection on mRNA expression of the endothelial vaso-active factors of patients with coronary heart disease and blood stasis. METHODS: Fifty-six patients were randomly divided into two groups:twenty-eight patients were treated according to the therapeutic guide for coronary heart disease as the control group and 28 were given the same treatment plus Xiangdan Injection as the treated group. The expressions of ET-1 and eNOS mRNA were examined with RT-PCR before experiment and ten days later. RESULTS: The positive rate of eNOS mRNA of the treated group increased, while the positive rate of ET-1 mRNA of the treated group decreased after ten day's treatment, with significant differences as compared with that before the experiment. Xiangdan Injection up-regulated the eNOS mRNA expression and suppressed the ET-1 mRNA expression. Changes of expression were not observed in the control group. CONCLUSION: Xiangdan Injection improves the endothelial function of patients with coronary heart disease and blood stasis by regulating the expressions of ET-1 and eNOS mRNA.

Objective To evaluate the expression of molecular markers in prostate cancer and to clarify the significance of these markers as prognostic indicators for androgen deprivation therapy. Methods A series of 116 prostate cancer patients under androgen deprivation therapy as a single treatment was reviewed. Expression levels of 7 proteins, including androgen receptor(AR),E-cadherin, Chromogranin A(CgA) , Ki-67, Survivin, EZH2 and hepsin, were measured by immunohistochemical staining. Results Of the 7 molecules. Ki67,EZH2 and Survivin expression were significantly associated with several conventional prognostic factors. Univariate analysis identified clinical stage, Glea-son scores,pretreatment serum PSA level, Ki-67 and Survivin expression as significant predictors for prostate-specific antigen (PSA) progression after endocrine therapy. Of these significant factors, Survivin expression, clinical stage and Gleason scores appeared to be independently related to PSA progression after endocrine therapy by multivariate analysis. Furthermore, there were significant differences in PSA progression-free survival according to positive numbers of these three independent risk factors. Conclusion Survivin could be a useful independent prognostic factor in prostate cancer with endocrine therapy, besides clinical stage and Gleason score.

Aims To investigate the protective effects of noninvasive limb ischemic preconditioning (LIPC) on myocardial ischemia-reperfusion (I /R)injury,and to explore the mechanism.Methods Healthy male Wistar rats were divided randomly into I /R,I /R +LIPC,I /R +5-Hydroxydecanoate (5-HD)and I /R +LIPC +5-HD groups.The I /R +LIPC and I /R +LIPC-5-HD groups of rats were subjected to three cy-cles of LIPC induction per day with 5 min of reperfu-sion after occlusion for 5 min at the left hind limb for 3 days.All rats were subjected to myocardial I /R injury on the fourth day.The I /R +5-HD and I /R +LIPC-5-HD groups of rats were given the inhibitor of ATP-sen-sitive potassium channel 5-HD before and during myo-cardial I /R injury. Results Compared with I /R group,LIPC reduced myocardial infarct size (P <0.05),lowered cardiocyte apoptosis index and Fas, FasL positive cell number (P <0.01 ),increased the reduced nitric oxide (NO)/endothelin (ET)-1 ratio (P <0.05)in serum in I /R +LIPC group.5-HD a-bolished the protective effects induced by LIPC in I /R+LIPC-5-HD group.Compared with normal myocardi-al tissue,expression of mir-30a-3p was increased in I /R group (P <0.01 )and was decreased in LIPC group (P <0.01 ).Conclusion LIPC alleviates myocardial I /R injury and improves endothelial function. The mechanism may be related with the opening of ATP-sensitive potassium channel,regulating the balance be-tween NO and ET-1 and decreasing the expression of myocardial mir-30a-3p.

Objective To explore the characteristics of attenuated plaque (AP) in culprit lesions for acute coronary syndrome (ACS) in elderly patients.Methods This study included 166 ACS patients meeting the conditions from Jan.1, 2013 to Sep.31, 2014.Clinical data, vascular lesions determined by coronary angiography and intravenous ultrasound (IVUS)-demonstrated characteristics of culprit plaque, which included presence of AP, maximum attenuation arc, extravascular elastic membrane area, lumen area, plaque area, plaque burden and remodeling index, were recorded.Results Compared with non-elderly group, elderly group had a higher proportion of multiple coronary-artery lesions (50.0％ vs.35.1％, x2=6.525, P =0.038), more attenuation plaques (62.0 ％ vs.45.9％, x2 =4.245, P=0.039), a larger maximum attenuation arc[(142±80)° vs.(115±54)°, t=5.254, P=0.000], larger plaque area[(14.2±3.9)mm2 vs.(12.3 ± 4.1) mm2, t=2.325, P=0.022], more plaque burden [(81.1±14.2)％ vs.(76.4±13.5)％, t=2.025, P=0.042] and higher remodeling index [(1.19±0.17) vs.(1.09±0.13), t=4.245, P=0.031].Conclusions The onset of ACS is more closely related with the unstable plaque in elderly patients, and strengthening the measures for plaque stabilization will be helpful in the prevention and treatment of ACS in the elderly.
