Objective To observe clinical application of the apparent Shikani laryngoscope in difficult airway, so as to provide reference for basic-level hospitals to deal with difficult airway. Methods 50 patients with difficult airway were randomly divided into 2 groups:Shikani laryngoscope group (S) that direct laryngoscope group (M) . After conventional induction, patients in two groups were given endotracheal intubation with different intubation tools by the same anesthesiologist, then the intubation time and the one-time success rate of intubation were compared between two groups. The hemodynamics of patients, were observed in two groups,the HR,SBP,DBP and SPO2 at before (T0),during (T1),2 min after (T2) and 5 min after intubation (T3) were recorded. The complications including gingival and oral mucosa bleeding, sore throat, hoarseness were also recorded in two groups.Results During the process of intubation, the hemodynamic changes of patients had statistically significant difference between T0 and T1, T2,T3 subgroups ( <0.05),T2 and T3 subgroups ( <0.05) . The intubation had less influence on hemodynamics of patients in group S than M group,but the SPO2 and T0 had no significant difference between two groups ( >0.05) .Comared with M group,the one-time success rate of intubation was higher,and the intubation time was shorter in S group and there were significant differences ( <0.05) . There was no significant difference in the intubation complications between the two groups ( > 0.05), and this may be associated with small sample cases. Conclusion Compared with ordinary laryngoscope, Shikani laryngoscope has incomparable advantages in handling difficult airway and is convenient to apply,so it is worth popularizing in basic-level hospitals.

Objective:To study the effect of diammonium glycyrrhizinate (DG) on left ventricular function impairment during myocardial ischemia－reperfusion in rats.　Methods:The left ventricular was cannulated through right common carotid artery on the myocardial ischemia－reperfusion injury model. The left ventricler function was assessed before and 10 minutes after the administration of DG, immediate and 20 minutes after initiation of ischemia, immediate and 30, 60 minutes after reperfusion, by measuring the left ventricular systolic pressure (LVSP), left ventricular end diastolic pressure (LVEDP), ＋dp*dtmax and －dp*dtmax. 　Results:Compared with the baseline, all measurements of LVSP, ＋dp*dtmax and －dp*dtmax decreased (P＜0.05,P＜0.01), while LVEDP increased (P＜0.01) after administration of DG. As the time of ischemia－reperfusion lasting, LVSP, dp*dtmax and －dp*dtmax generally decreased progressively, while LVEDP generally increased progressively. 20 minutes after the initiation of ischemia and immediate, 30 and 60 minutes following reperfusion, LVSP, ＋dp*dtmax and －dp*dtmax in the DG group were significantly higher than those in IR group (P＜0.01), LVEDP significantly lower than that in IR group (P＜0.01) at the same time. 　Conclusion:DG can protect left ventricular function against myocardial ischemia－reperfusion injury in rats.

Objective: To investigate the role of prostate specific antigen(PSA) in screening for prostate cancer. Methods: The serum PSA of 4 848 males over 50-years old for serum PSA was evaluated,respectively out of them 33 cases diagnosed as prostate cancer(screening group) were compared in terms of age distribution,level of PSA,clinical stages,Gleason score and treatment modalities with 28 patients in our hospital(clinical group). Results: In the screening group,the positive percentage account for 9.5%(PSA≥4 ng/ml) and the PCa positive rate was 6.8‰(33/4 848).The average age of the patients(73.2?8.0) was insignificant different between these two groups.The percentage of the cases beyond 20 ng/ml PSA in the screening group was significantly lower than that in clinical group,with 42.4% and 71.5% respectively.Furthermore,the cases with clinical stage A+B accounted for 69.7% in the screening group,while it was 35.7% in the clinical group(P

[Objective]To investigate the diagnosis,surgical procedure and clinical effect for the subdural extramedullary tumor. [Methods]Forty-five patients (28 males and 17 females,age ranged from 24-71 years with an average of 45 years ) were treated with tumour extirpation. MRI showed subdural extramedullary tumor before surgery. The spine was exposed through a standard posterior approach,and the dura matter was opened after lamninectomy. The tumor was separated and removed from the dura matter. Pedicle screw fixation was performed to restore the stability of spine. [Results]The patients were followed up from 6 to 42 months with an average of 26.2 months. The postoperative recovery of neurological function was measured with Otani scores. The clinical result was excellent in 11 patients,good in 18 and fair in 12,resulting in 64.44% of good to excellent rate. The good to excellent rate had an advantage in patients (84.62%) operated on within one month after first visit over that of patients (64.29%) who had a misdiagnosis for 1~6 months and the patients (50.00%) for more than 6 months.[Conclusion]Removal is the method of choice for patients with subdural extramedullary tumor. Early diagnosis and removal are key factors to get a good clinical effect.

Objective To evaluate the effect of radiofrequency catheter ablation treament of supraventricular tachyarrhythmias on spontaneous attack of atrial fibrillation (AF) and to further discuss the electrophysiological mechanisms of AF. Methods Thirty-one patients (20 men, 11 women; mean age 54?12 years, age range 24-69 years) with supraventricular tachyarrhythmias coexisting with AF were included in the study. The mean history of the study group was 9?5 (range 1-19) years and the mean number of AF attack was 6?5 times (range 2-18). Of the 31 cases, 5 supraventricular tachyarrhythmias were electrophysiologically proven to be typical atrial flutter (AFL), 17 atrioventricular reentrant tachycardia (AVRT), 9 atrioventricular nodal reentrant tachycardia (AVNRT). Linear lesions to make bi-directional block were done in cavo-tricuspid isthmus in AFL patients, slow pathway modification in AVNRT and accessory pathway ablation in AVRT. Results After mean follow-up of 39?19 months (range 12-72), of the 31 patients, 23 had no occurrence of AF. In 3 of the 5 AFL patients, no AF occurred after ablation, but 2 still had AF occurrence, of whom one had frequent atrial premature contractions (APCs) and short runs of AF. In 26 patients with supraventricular tachycardia, 20 had no occurrence of AF after ablation. In the remaining 6, 2 had less frequent occurrence, and 4 remained the same, of whom one had hypertention with enlarged left atrium, and another had frequent APCs and short runs of atrial tachycardia. Conclusion AFL may share the same substrate with AF or may be the trigger factor of AF, and AVNRT and AVRT are only trigger factors of AF. So after successful ablation treatment of these tachycardias, no AF occurs. But in some cases, AF substrate still exists, and AF can be triggered by other trigger factors besides tachycardias mentioned above.

Objective To systematically review the short-term and long-term efficacy of eversion carotid endarterectomy (eCEA) and patch carotid endarterectomy (pCEA) for the treatment of carotid artery stenosis.Methods The published literature on eCEA and pCEA control studies in medline,PubMed,Ovid,CNKI and CBM (1970.5-2016.10) databases were retrieved by computers.Two reviewers selected literature and extracted data independently according to the inclusion and exclusion criteria.Cochrane Collaboration Network Special Software Rev Man 5.2 was used to analyze the meta-analysis of short-term and long-term outcome measures.Results A total of 1 137 articles were retrieved.Ten studies were included and analyzed (3 of them were randomized controlled trial).A total of 3 213 patients were enrolled,including surgical intervention 3 299 case/time (1 512 in the eCEA group and 1 787 in the pCEA group).The results of meta-analysis showed that:(1) the mean operative time in the pCEA group was shorter 22±8 min than that in the pCEA group.The intraoperative utilization ratio of shunt tube,eCEA was significantly lower than pCEA,they were 12.6 %(53/421) and 50.2% (357/711) respectively (OR,0.11,95%CI 0.08-0.15,P<0.01).The postoperative incidence of stroke within 30 d (OR,0.42,95%CI 0.23-0.76,P=0.004) and the incidence of stroke after 30 d in eCEA were lower than those in pCEA (OR,0.26,95%CI 0.09-0.78,P=0.02).There was significant difference.(2) eCEA reduced the incidence of restenosis at day 30 after procedure (OR,0.57,95%CI 0.38-0.86,P=0.008).Conclusion Compared with pCEA,eCEA has the advantages of reducing the operation time and lowering the utilization rate of shunt tube.At the same time,eCEA can reduce the occurrence of stroke within 30 d and 30 d after procedure,and significantly reduce the incidence of restenosis.
