Objective To compare the efficacy of the laryngeal mask airway Classic (CLMA), Streamlined Liner of Pharyngeal Airway (SLIPA) and laryngeal mask airway ProSeal (PLMA) in patients undergoing laparoscopic surgery. Methods One hundred and twenty-three ASA Ⅰ or Ⅱ patients aged 20-64 yr undergoing elective laparoscopic surgery were randomly divided into 3 groups: CLMA group (group C, n =41 ), SLIPA group (group S, n =42) and PLMA group (group P, n =40). Laryngeal mask was inserted after induction of anesthesia with sufentanil 0.3 μg/kg, atracurium 0.5 mg/kg and propofol 2 mg/kg. Mll the patients were ventilated with intermittent positive-pressure ventilation. Anesthesia was maintained with contiunous infusion of propofol 6-8 mg· kg-1· h-1 and with supplementary administration of sufentsnil 0.1-0.2 μg/kg and atracurium 0.2 mg/kg as required. The degree of difficulty in inserting the laryngeal mask was evaluated. The rate of successful placement at first attempt, device placement time, recovery time and complications were recorded . Peak inspiratory pressure (PIP) and the number of patients with an airway sealing pressure less than PIP were recorded before pneumoperitoneum and when intra-abdominal pressure achieved 12 mm Hg. Results The placement was easier and the placement time and recovery time were significantly shorter in group S, and the placement time was significantly longer,the airway sealing pressure was significantly higher and the number of patients with an airway sealing pressure less than PIP was lower in group P than in group C ( P < 0.05). The placement time and recovery time were significantly longer, the placement was harder, the airway sealing pressure was significantly higher, and the number of patients with an airway sealing pressure less than PIP was lower in group P than in group S ( P < 0.05). PIP was significantiy higher when intra-abdominal pressure achieved 12 mm Hg than that before pneumoperitoneum in all the three groups ( P < 0.05). There was no significant difference in the incidence of complications and rate of successful placement at first attempt among the three groups ( P > 0.05). Conclusion All the three airway devices can provide adequate ventilation during operation, with fewer complications. SLIPA placement is easiest. PLMA can assure good airway sealing and is most suitable for patients undergoing laparoscopic surgery.

OBJECTIVETo investigate the association between pulmonary vascular remodeling and expression of hypoxia-inducible factor-1α (HIF-1α), endothelin-1 (ET-1) and inducible nitric oxide synthase (iNOS) in pulmonary vessels in neonatal rats with hypoxic pulmonary hypertension (HPH).
METHODSA neonatal rat model of HPH was established as an HPH group, and normal neonatal rats were enrolled as a control group. The mean pulmonary arterial pressure (mPAP) was measured. The percentage of medial thickness to outer diameter of the small pulmonary arteries (MT%) and the percentage of medial cross-section area to total cross-section area of the pulmonary small arteries (MA%) were measured as the indicators for pulmonary vascular remodeling. The immunohistochemical reaction intensities for HIF-1α, ET-1 and iNOS and their mRNA expression in lung tissues of neonatal rats were measured. Correlation analysis was performed to determine the relationship between pulmonary vascular remodeling and mRNA expression of HIF-1α, ET-1 and iNOS.
RESULTSThe mPAP of the HPH group kept increasing on days 3, 5, 7, 10, 14, and 21 of hypoxia, with a significant difference compared with the control group (P<0.05). The HPH group had significantly higher MT% and MA% than the control group from day 7 of hypoxia (P<0.05). HIF-1α protein expression increased significantly on days 3, 5, 7 and 10 days of hypoxia, and HIF-1α mRNA expression increased significantly on days 3, 5 and 7 days of hypoxia in the HPH group compared with the control group (P<0.05). ET-1 protein expression increased significantly on days 3, 5 and 7 days of hypoxia and ET-1 mRNA expression increased significantly on day 3 of hypoxia in the HPH group compared with the control group (P<0.05). Both iNOS protein and mRNA expression were significantly higher on days 3, 5 and 7 days of hypoxia than the control group (P<0.05). Both MT% and MA% were positively correlated with HIF-1α mRNA expression (r=0.835 and 0.850 respectively; P<0.05).
CONCLUSIONSPulmonary vascular remodeling is developed on day 7 of hypoxia in neonatal rats. HIF-1α, ET-1 and iNOS are all involved in the occurrence and development of HPH in neonatal rats.

BACKGROUNDThe aim of this study was to clarify the electrocardiographic characteristics of repetitive monomorphic ventricular tachycardia (RMVT) originating from the left ventricular outflow tract, and to describe the results of treatment with radiofrequency catheter ablation (RFCA).
METHODSRoutine 12-lead surface electrocardiography and electrophysiological studies were performed on 11 RMVT patients with no organic heart disease, who were subsequently treated with RFCA directed at targets identified by pace mapping.
RESULTSThe surface electrocardiogram QRS characteristics of RMVT included an atypical left bundle branch block and right axis deviation, with a low amplitude "rs" or "rS" pattern in lead I, an "rS" or "RS" pattern in V1, and a precordial R wave transition zone in V2 or V3. In 1 patient, a small S wave was observed in V5. Using pace mapping techniques, we selected the left coronary cusp as the ablation target. RMVT was eliminated in all 11 patients immediately after radiofrequency energy delivered. During a follow-up of 13 +/- 7 months, RMVT recurred in only 1 patient.
CONCLUSIONRMVT originating from the left ventricular outflow tract has specific electrocardiographic characteristics, and can be successfully and safely cured using RFCA directed at the left coronary cusp.
