Objective:To investigate the plastic method of glottis carcinoma in surgery. Method:Retrospectly analyzed 29 patients with T_2 ,T_3 glottis carcinoma who admited in our department From 1996 to 2004. All of them were treated with the displacement of ventricular bands-epiglottis mucosal flap in the surgical management of glot-tis carcinoma. The tumour was primarily from vocal cords, and not exceeded 2cm. Result: All cases were success-fully renovated laryngeal cavity with the displacement of ventricular bands-epiglottis mucosal flap and followed up for 5 years after operation. Three years survival rate was 86.2% ,5 years survival rate was 78.9% ,and tube draw-ing rate was 100%. Conclusion: With this method, surgery would be simplified and the patients would keep the voiced function and swallowing function.

Objective To explore the efficacy of duo positive airway pressure ventilation in treating preterm infant with neonatal respiratory distress syndrome (RDS). Methods 65 preterm infants admitted to the neonatal intensive care unit from December 2012 to December 2013 were randomly divided into DuoPAP group (34 cases) or NCPAP (31 cases) group. Blood gas analysis(pH value, PaO2, PaCO2 and OI) at 1h, 12h, 24h, and 72h, and incidence of apnea, pulmonary air leak, repeated application of pulmonary surfactant and non-invasive ventilation failure at 72h in the two groups were measured and compared after using intubate surfactant extubate (INSURE). Results OI after non-invasive ventilation at 1h, 12h, and 24h was signiifcantly higherin DuoPAP group than that in NCPAP group P<0.01). PaCO2 after non-invasive ventilation at 1h, 12h, 24hand 72h was signiifcantly lower in DuoPAP group than that in NCPAP group (P<0.01). PaO2 after non-invasive ventilation at 1h and 12h was higher in DuoPAP group than that in NCPAP group, and there was signiifcant difference between the two groups (P<0.01). The incidence of non-invasive ventilation failure, apnea in 72h was lower in DuoPAP group than that in NCPAP group, and there was signiifcant difference between the two groups (P<0.05). Conclusions Compared with NCPAP, DuoPAP is more feasible for improving oxygenation, decreasing the need for mechanical ventilation in 72h in preterm infants with neonatal RDS.

Objective To investigate the characteristics and plausible mechanisms of attention network impairments in hyperthyroid patients.Methods 34 hypertyroid patients and 33 normal controls performed the attention network test (ANT),which was used for assessing three components of attentional networks including alerting,orienting,and executive control.Results The mean scores for alerting and orienting networks were significantly shorter (P ＜ 0.01) in hyperthyroid patients (respectively,(20.00 ± 22.47) ms,(35.26 ± 22.65) ms)than those in normal controls (respectively,(35.70 ± 17.62) ms,(50.61 ± 23.66) ms).The mean reaction time for executive control network was significantly longer(P ＜ 0.01) in hyperthyroid patients((116.71 ± 40.36)ms)than those in controls ((93.00 ± 29.34)ms).Triiodothyronine(T3) and thyroxine(T4) were positively correlated with the scores for executive control network (respectively,r=0.350,P＜ 0.05; r=0.417,P＜ 0.05) in hyperthyroid patients,whereas no relationship was found between thyroid stimulating hormone(TSH) and the value of executive control network.T3,T4 and TSH were not correlated with the value of alerting and orienting network in hyperthyroid patients.Conclusion Hypertyroid patients have extensive impairments in various kinds of attentional network,rather than a specific deficit.The recession of executive control network accompanies with enhancement of serum levels of T3,T4 in hyperthyroid patients.

Objective To evaluate the risk of hyperuricemia in patients younger than 45 with coronary artery disease.Methods Six hundred and seventy-seven patients with coronary artery disease under 45 years old at disease onset were recruited retrospectively.The subjects were divided into hyperuricemia group (n=164) and normal uric acid group (n=513).Patients with coronary artery disease with hyperuricemia were analyzed for clinical characteristics.The risk of hyperuricemia was analyzed on the severity of coronary lesions.T-test,x2 test and Logistic regression analysis were used for statistical analysis.Results Comparing with patients with normal uric acid,patients in the hyperuricemia group were male predominant and more prevalent with hypertension [197(38.5％) and 93(56.7％) ; x2=16.85,P＜0.01],hypedipidemia [274(53.4％) and 130 (80.7％); x2=37.58,P＜0.01],and cardiac dysfunction [24 (4.7％) and 17 (10.4％); x2=7.18,P=0.01].Hyperuricemia increased the risk of coronary artery disease complicated with cardiac dysfunction [ORlcorrection=2.66,95％CI (1.28,5.53)],and it also increased the risk of coronary artery disease concurrent with cardiac arrhythmia [OR2correction=1.28,95％CI (1.00,1.65)] revealed by multivariate regression analysis.Conclusion In young patients under 45 years old with coronary artery disease,hyperuricemia is the independent risk factor for coronary artery disease complicated with cardiac dysfunction and arrhythmia.
