Objective To investigate the clinical efficacy of drug-eluting stent( DES) combined with clopi-dogrel therapy in patients with coronary heart disease. Methods 123 patients underwent percutaneous coronary intervention (PCI) were randomly divided into observation group (DES) of 60 cases and the control group ( bare-metal stent,BMS) of 63 cases. The observation group was given the treatment of DES combined clopidogrel, the control group was given the treatment of BMS combined clopidogrel. The stent implantation and the follow-up two-year MACE were observed. Results (1) The average implanted stent length of the observation group was longer than that of the control group(P<(0.05) ,the angiography in vascular disease and complexity between the two groups had no significant difference ( P > 0. 05 ) ; the success rate of surgery in the two groups was 100% , after operation the TIMI flow reached grade 3. (2) The incidence of angina pectoris and revascularization rate of the observation group was significantly lower than that of the control group (P < 0.05); the rate of coronary angiography, recurrent myocardial infarction and the incidence of cardiac death between the two groups had no significant difference ( P > 0.05). Conclusion DES combined with clopidogrel maintenance therapy for a year in patients with coronary heart disease had a good long-term efficacy.

Objective:To study dynamic change of brain natriuretic peptide (BNP),left ventricular ejection fraction (LVEF)and prognosis improvement in patients with acute anterior myocardial infarction (AAMI)complicated hy-poxemia after noninvasive mechanical ventilation therapy.Methods:A total of 60 patients with AAMI complicated hypoxemia,who were hospitalized in our hospital from Mar 2011 to Oct 2013,were divided into noninvasive venti-lation group (n=28)and routine treatment group (n=32)according to number table.Dynamic change of BNP, LVEF and prognosis were observed and compared between two groups.Results:After treatment,BNP level and LVEF significantly improved in both groups (P<0.05 all),compared with routine treatment group,there was more significant reduction in BNP level [24h:(263.6±23.3)μmol/L vs.(126.2±21.9)μmol/L]and significant rise in LVEF [(40.6±13.1)% vs.(47.3±14.7)%]in noninvasive ventilation group after treatment (P<0.01 both);af-ter 30d follow-up,there were significant rise in 6min walking distance (percentage of 426~550m,59.3% vs. 75.0%),LVEF [(41.1±11.7)% vs.(49.4±12.5)%]and survival rate (90.6% vs.96.4%),and significant re-duction in rehospitalization rate (12.5% vs.7.1%)in noninvasive ventilation group,P<0.01 all.Conclusion:Ear-ly noninvasive mechanical ventilation therapy can significantly improve cardiac function,exercise tolerance and short-term prognosis in patients with acute anterior myocardial infarction complicated hypoxemia.

In order to determine immunogenicity and protective effect in chickens, we used the IBDV (Infectious bursal disease virus)-Vp2/Lactobacillus casei as antigen transfer system. First, the immunized and control chickens were challenged by IBDV/DQ at lethal dose to determine the protective ratio. Second, chickens were orallyand intranasally vaccinated twice with 10(9) CFU/mL pLA-VP2/L. casei, pLA/L. casei and PBS as negativecontrol and commercial vaccine as positive control. The bursa injury and the lesion score wererecorded post challenge. The level of specific IgG and sIgA in pLA-VP2/L. casei and positive control groups was significantly higher than that in negativecontrol groups. The protection efficacy in pLA-VP2/L. casei oral group was higher than that inintranasal group. The SI. of pLA-VP2/L. casei oral group was significant higher than other groups. The lesion score indicated the pLA-VP2/L. casei was safer than commercial vaccine for bursa. Collectively, the pLA-VP2/L. casei could be a vaccine candidate for IBDV.

Objective: To investigate the expression of long non-coding RNA(lncRNA) uc003jsd.1 in congenital microtia and its clinical significance. Methods: Real-time quantitative polymerase chain reaction (Real-time PCR) was used to detect the expression of lncRNA-NR_028308 in the residual ear cartilage and normal ear cartilage of 8 patients with microtia. Results: The expression of uc003jsd.1 was significantly higher in the residual ear cartilage (P=0.015) than paired normal tissues. Conclusions LncRNA-uc003jsd.1 is up-regulated in the cartilage of the congenital microtia, suggesting a certain relationship with the development of congenital microtia.

Objective: To evaluate whether restricted breathing movement by wearing elastic chest belt within half a year postoperatively could decrease the incidence of chest wall deformity after costal cartilage harvesting. Methods: The contour of chests of the patients receiving the third-stage operation of auricular reconstruction was assessed 1 year after costal cartilage harvesting with history collection and physical examination. The incidence of costal wall deformity was summarized and compared by wearing elastic chest belt or not within half a year postoperatively. Logistic regression was used to analyze the significance of results. Results: Thirty-eight eligible patients were enrolled in the study. The incidence of chest wall deformity in patients wearing chest elastic chest belt as requested for half a year was lower (64.7% vs. 95.2%), and the difference was statistically significant, OR 10.9, 95%CI[1.16, 102.60], P=0.037. Conclusions Restricted breathing movement by wearing elastic chest belt within half a year postoperatively could decrease the incidence of chest wall deformity following costal cartilage harvesting through decreasing the traction force caused by respiratory muscles and intrathoracic negative pressure.

Objective To explore the differential diagnosis of Meige syndrome (MS) with hemifacial spasm (HFS) to strengthen the degree of recognition of MS for clinical workers.Methods The clinical data of 10 patients with MS,misdiagnosed as HFS and received microvascular decompression (MVD) surgery in other hospitals and admitted to our hospital from May 2005 to November 2016,were retrospectively analyzed.The different differential diagnosis methods and treatment methods were analyzed.Results These 10 patients with MS,who were misdiagnosed as different sides of HFS,took oral drugs,acupuncture therapy,botulinum toxin injection and facial nerve MVD treatments before they went into our hospital.Relapse appeared in these patients at about 2 years.However,in our hospital,these 10 patients were diagnosed as having MS.According to their clinical symptoms,corresponding treatment regimens for symptomatic treatment were given:2 patients underwent deep brain stimulation,and 8 patients with oral medication and psychological and behavioral therapies.The eyelid and lips and involuntary symptoms of convulsions improved significantly.Burke-Fahn-Marsden muscular dystonia rating scale indicated that the improvement rate in the 2 patients accepted deep brain stimulation was 54％-89％,and that in the other 8 patients was 23％-59％.Conclusions MS and HFS have a certain degree of similarity in clinical manifestations,and it is easily confused in the clinical work.But the two are completely different in pathogenesis and treatment,and the wrong treatment may bring disastrous consequences to patients,so it's a great challenge for clinicians to make a clear diagnosis.

Objective To evaluate the effect of urapidil on myocardial reperfusion and cardiac function during primary percutenons coronary intervention (PCI) in acute myocardial infarction (AMI) patients.Methods 54 AMI patients undergoing primary PCI were randomized to intracoronary urapidil (n=27) and nitroglycerin (n=27) group.When blood flow grade TIMI-l or more appeared in the infarct related artery (IRA) before or after percutenous transluminal coronary angioplasty (PTCA),urapidil (12.5 mg) or nitroglycerin (0.2 mg) was given intracoronary and then stents were implanted as needed.TIMI blood flow,no reflow/slow floW,corrected TIMl frame count (cTFC),myocardial blush grade (MBG),ST resolution (STR) on ECG, peak of creatine kinase (CK),cardiac troponin T (cTnT) were observed before and after PCI.Left ventricular ejection fraction (LVEF) was measured 24 hours and 30 days after PCI and MACE including death,reinfartion,revascularization in hospital were observed. Resuits Urapidil group compared to the nitroglycerin group,cTFC (18.38±3.30 vs.21.44±4.26,P=0.005) decreased and MBG (P=0.040) improved.STR in the urapidil group improved significantly compred to the nitroglycerin group (93% vs.70%,P=0.038).LVEF of 24 hours and 30 days after PCI in the urapidil group was higher than that ofthe nitroglycerin group (0.55±0.05 vs.0.52±0.06,P=0.021 and 0.58±0.06 vs 0.54±0.06,P=O.041,respectively).Peak CK (1895.26±1239.02 vs.1269.96±515.84,P=0.021) and peak TnT (5.81±5.27 vs 3.64±2.35,P=0.050) in the urapidil group decreased more significantly than that of the nitroglycerin group.No difference of MACE was found in the two groups.Conclusion Intracoronary urapidil administration adjunct to primary PCI in AMI ameliorates coronary blood flow and myocardial perfusion, improves ventricular function,and reduce the infarct size and does not incllase the incidence of complications during hospitalization.

AIM:To investigate the role of Rho-associated kinase ( ROCK) inhibitor fasudil in the formation of rabbit urethral stricture after injury and to observe the cell activity , migration and extracellular matrix synthesis in the rabbit urethra fibroblasts.METHODS:The rabbit model of urethral stricture was established by microsurgical techniques .The rabbits were divided into sham operation group , operation group and fasudil (3 mg/kg, 10 mg/kg, 30 mg/kg) groups.The diameter of the stenosis was measured by retrograde urethrography 3 months after surgery .The fibroblasts were isolated from urethral scar, and then incubated with fasudil (12.5 μmol/L, 25 μmol/L, 50 μmol/L) in the presence of transforming growth factor-β1 (TGF-β1, 10 μg/L).The untreated cells were used for control .The cell activity was measured by MTT assay.The cell migration ability was tested by the method of Transwell chambers .The protein expression of ROCK , α-smooth muscle actin (α-SMA) , collagen I and collagen III was determined by Western blot analysis .RESULTS:Fasudil significantly reduced formation of urethral stricture after injury (P<0.05).Cultured rabbit fibroblasts with different con-centrations of fasudil inhibited the cell activity and cell migration ability (P<0.05).The protein expression of ROCK,α-SMA, collagen I and collagen III was also inhibited by treatment with fasudil in a dose -dependent manner ( P<0.05 ) . CONCLUSION:Fasudil inhibits the formation of extracellular matrix and reduces the incidence of urethral stricture after injury by down-regulating TGF-β1-induced Rho/ROCK pathway activation in the rabbit urethra fibroblasts .

Objective To investigate the safety and clinical efficacies of microvascular decompression(MVD) on cranial neuropathy such as trigeminal neuralgia (TN),hemifacial spasm (HFS)and glossopharyngeal neuralgia(GN)in elderly patients.Methods Clinical data of 72 patients aged 70 years and over diagnosed as cranial neuropathy and undergoing microvascular decompression in our department from January 2015 to August 2017 were retrospectively analyzed.The curative effect and complications were analyzed after treatment.Results All patients successfully underwent MVD under general anesthesia.The facial pain completely disappeared or was significantly improved in 85.7 ％ (30/35)of TN patients one year after operation.The intermittent tonic contractions of the facial muscles were completely disappeared in 94.3％ (33/35)of HFS patients.Clinical symptoms were completely disappeared in 2 patients with GN,4 patients with TN and HFS and 1 patients with TN and GN.Conclusions The surgery goes well and the patients have good postoperative recovery,with no severe complications such as intracranial hematoma,infarction,cerebrospinal fluid leakage,acute hydrocephalus and death.After an adequate preoperative evaluation,MVD is safe and effective with a few complications.It can significantly improve the quality of life in elderly patients with trigeminal neuralgia,hemifacial spasm,and glossopharyngeal neuralgia.

Objective: To summarize the clinical effect of using the composite flap of microtic cartilage and soft tissue in tragus reconstruction to correct preauricular depression. Methods: From January 2015 to November 2016, we corrected preauricular depression of 523 patients with congenital microtia that were treated with tragus reconstruction by using the composite flap of residual ear cartilage and soft tissue. Results: All the composite flap of residual ear cartilage and soft tissue were transplanted successfully. No blood circulation disorder and significant contracture occurred. All patients were followed up for 6-14 months with an average of 10 months. The reconstructed tragus looked projective and the preauricular depression was corrected, demonstrating a similar looking to the healthy side. The patients were satisfied with the results. Conclusions The residual ear tissue could form the composite flap of residual ear cartilage and tissue. Using the composite flap to fill the preauricular depression was effective, which was not easily absorbed. The residual ear tissue is the best resource for filling the preauricular depression. It should not be discarded in ear reconstructive surgery, but reserved for the next operation for tragus reconstruction.
