Objective To compare the efficacy of the streamlined liner of the pharynx airway (SLIPA) and the proseal laryngeal mask airway (PLMA) in airway management in elderly patients undergoing laparoscopic cholecystectomy.Methods One hundred and twenty patients aged 60-75 years with American Society of Anesthesiologists (ASA) grade] or Ⅱ undergoing laparoscopic cholecystectomy were randomly divided into three groups:the endotracheal intubation group (Group T,n=40),the SLIPAgroup (GroupS,n=40) and the PLMA group (GroupP,n=40).Endotracheal intubation and laryngeal mask airway insertion were conducted after induction of anesthesia.All the patients were ventilated with intermittent positive pressure ventilation.Mean arterial pressure and heart rate were recorded at before induction (T0),successful insertion (T1),ten minutes after pneumoperitoneum (T2),successful extubation (T3),and ten minutes after extubation (T4).The rate of successful placement at first attempt,time taken for placement,airway sealing pressure,and side effects were recorded.The incidences of post-extubation cough,backflow,aspiration,larynogospasm,bleeding,gastric distension and sore throat within 2 days after intubation were also recorded.Results The successful rates of insertion were 92.5 ％,92.5 ％,95.0 ％,respectively,at first attempt and 100.0％ at second attempt in the three groups (x2 =0.268,P＜0.05).Changes in hemodynamic parameters were significantly different between Group T and Group S or P after induction (t=4.076,P＜0.05).Time taken for placement was shorter in Group S than in Groups T and P,meaning that the placement of SLIPA was easier than that of endotracheal intubation or PLMA (t=43.561,P＜0.05).The airway sealing pressure was higher in Group P than in Group S,but had no statistically significant difference between the two groups (t=0.363,P＞0.05).There was no significant difference in post extubation complications,including backflow,aspiration,laryngospasm and gastric distension (t=0.321,P＞0.05),among the three groups,but incidences of postextubation cough and pharyngalgia were higher in Group T than in Group S and Group P (x2 =26.674,10.568,P＜0.05).Conclusions SLIPA and PLMA can both provide adequate ventilation during operation,with few complications.SLIPA placement is the easiest,while PLMA has good airway sealing and thus is more suitable for elderly patients undergoing laparoscopic cholecystectomy.

This paper focus on conductive education approach during exercise therapy of cerbral palsy childrens, which emphasis the children active participation in the exercises and their phsycological reactions. Its main feature is using the rythmicl intention, task analysis and task series as the tools to perform the goal - directed activities in group setting and carry it out in the children' s daily life. The current studies on the motor control and motor learning are reviwed in this paper as well.

Chlorella pyrenoidosa No.2 was screened from five species of microalga Chlorella sp. for its higher lipid yield. Effects of medium components and culture conditions on cell growth as well as lipid ac-cumulation of C. pyrenoidosa No.2 were investigated and the results showed that the optimum medium rec-ipe was 20.0 g/L glucose,0.08 g/L glycine,1.0 g/L K2HPO4?3H2O,0.4 g/L MgSO4?7H2O and 0.004 g/L FeSO4?7H2O. The optimum culture temperature,initial pH,shaking rate and light intensity were 28℃,6.0,130 r/min and 650 Lux,respectively. Biomass and lipid content increased from 3.73 g/L and 40.15% to 6.56 g/L and 59.90% when Chlorella pyrenoidosa No.2 was cultivated under the above optimal conditions for 7 days,with lipid yield raised by 162%. Chlorella pyrenoidosa No.2 could produce lipid with xylose as carbon source,and so is potential for lipid production from renewable materials such as lignocellulose. GC analysis demonstrated that the fatty acid composition of the lipid was similar to that of vegetable oil and its unsaturated fatty acid content reached around 71%,thus it is a promising material for biodiesel production.

Objective To assess the predictive value of plasma level of calcitonin gene related peptide for cardiovascular events and operational stent restenosis after coronary stent implantation in 6 months.Methods Plasma level of CGRP was measured in 53 cases of coronary stent implantation before and after the operation.The cardiovascular events and the stent restenosis were observed and recorded in 6 months after the procedure.Results The plasma level of CGRP was significantly lower in patients with cardiovascular events and stent restenosis(166.36?10.18,182.5?11.36,P

ObjectiveTo investigate the feasibility and influence factors of a new silver salt method for determination of arsenic in drinking water. Methods Arsenic was determined at different reaction temperature,acidity, specification and addition of zinc granular, fill weight of lead acetate cotton, and the effect of these factors on assay results was observed. Arsenic in drinking water was determined in accordance with standard test methods (GB/T 5750.6) of the new silver method. Results The recoveries of the arsenic were 75.3％ - 93.6％(F =9.21,P ＜ 0.01 ) with reaction temperature at 10 - 30 ℃, and the best reaction temperature was 25 ℃. The recoveries of the arsenic ranged from 80.3％ - 91.6％(F =4.67, P＜ 0.05) when sulfuric acid was 3.0 - 6.0 ml and the best value was 5.0 ml. The recoveries of the honeycomb structural zinc granular(diameter 0.2 - 0.3, 0.3 - 0.4 mm) and button zinc granular were 87.2％, 90.7％ and 83.0％, respectively; the best specification was 0.3 - 0.4 mm. The recoveries of zinc granular weight(3 - 5 g ) were 74.6％ - 91.7％, respectively; the best was 5 g. The recoveries ranged from 79.6％ - 91.3％ with fill weight of lead acetate cotton at 25 - 100 mg, the best fill weight was 50 mg.The recoveries of the arsenic were 90.7％, 92.5％, 81.5％ and 74.2％ with lead acetate cotton length at 0.5 - 2.0 cm,and the best loose-tight degree was 1.0 cm. The stability time of arsine solution was 5.0, 4.0, 2.5 h with corresponding temperature at 20, 25, 30 ℃, respectively. ConclusionsIn order to ensure precision and accuracy of the measurement, it is necessary to control reaction temperature, acidity, specification and addition of zinc granular free from arsenic, fill weight of lead acetate cotton and loose-tight degree in the reaction system.
