Objective To explore the efficacy of low tidal volume ventilation strategy in children with acute hypoxia respiratory failure (AHRF).Methods A total of 79 hospitalized children with AHRF from Aug 2006 to Jul 2011 in PICU of Kunming Children's Hospital were enrolled in this study.The observation group in-cluded 55 children who received low tidal volume ventilation strategy (6-8 ml /kg),while the other 24 children (control group)were given traditional mechanical ventilation (10-12 ml /kg).Oxygenation situations such as PaO2 ,PaCO2 ,PaO2 /FiO2 ,oxygen index and blood gas pH value,organ function,mechanical ventilation complica-tions,hospitalization days and expenses in PICU and the mortality were observed.Results (1)PaO2 ,PaO2 /FiO2 and oxygen index in the observation group were better than those in control group after 24 h mechanical ventilation [(68.51 ±7.53)mmHg(1 mmHg =0.133 kPa)vs.(61.64 ±9.28)mmHg,(162.9 ±21.84)mmHg vs.(152.1 ± 19.03)mmHg,and 18.85 ±4.1 vs.26.53 ±5.2,respectively],and there were significant differences between two groups (P ﹤0.05);and there were also significant differences between two groups in the results after 48 h and 72 h mechanical ventilation.(2)The PaCO2 was (47.48 ±10.52)mmHg after 24 h in observation group,while the PaCO2 in control group was (30.17 ±6.59)mmHg,and it suggested excessive ventilation.(3)Mechanical venti-lation time (7.6 ±3.1)d and hospitalization days (12.8 ±3.6)d were shorter in observation group(P ﹤0.01). Barotrauma (7.3%)and mortality (20.0%)in observation group was significantly lower than those in control group (29.2%,41.6%;P ﹤0.01).The number of damaged organs in observation group was lower than that in control group (P ﹤0.05).Conclusion Low tidal volume ventilation with appropriate positive end expiratory pressure could improve oxygenation,prevent alveolar collapse,reduce complications and mortality for children with AHRF,it should be applied for the treatment of children with AHRF.

Objective To explore the effect of experimental design in the experimental teaching of fundamental nursing. Methods 168 and 199 baccalaureate nursing students were in the control and experimental group respectively, the control group received traditional experimental teaching method, and the experimental group must complete the experimental design before entering the lab. The teaching effect between the two groups were compared. Results The mean operation score of the experimental group was significantly higher than the control group, the proportion of those students who reflected their teaching method could enhance creative ability, problem-solving ability and practical ability was higher in the experimental group, 100% teachers reflected experimental design could improve operation level, strengthen theoretical knowledge, animate teaching atmosphere. Conclusions Experimental design could arouse students' enthusiasm and initiative to study, advocate them to think and ask.

7.Prone positioning ventilation for treatment of acute lung injury and acute respiratory distress syndrome.
Chinese Journal of Traumatology 2009;12(4):238-242
Patients who are diagnosed with acute lung injury/acute respiratory distress syndrome (ALI/ARDS) usually have ventilation-perfusion mismatch, severe decrease in lung capacity, and gas exchange abnormalities. Health care workers have implemented various strategies in an attempt to compensate for these pathological alterations. By rotating patients with ALI/ARDS between the supine and prone position, it is possible to achieve a significant improvement in PaO2/FiO2, decrease shunting and therefore improve oxygenation without use of expensive, invasive and experimental procedures. Prone positioning is a safe and effective way to improve ventilation when conventional strategies fail to initiate a patient response. Because a specific cure for ARDS is not available, the goal is to support the patients with therapies that cause the least amount of injury while the lungs have an opportunity to heal. Based on current data, a trial of prone positioning ventilation should be offered to the patients who have ALI/ARDS in the early course of the disease. Published studies exhibit substantial heterogeneity in clinical results, suggesting that an adequately sized study optimizing the duration of proning ventilation strategy is warranted to enable definitive conclusions to be drawn.

Objective To investigate the changes of lead,zinc,copper,iron and calcium in blood of chronic poisoned infantal mice.(Methods) Forty-eight 21 day-old kunzea mice were randomly divided into 4 groups,each having 12 mice.Distilled water group was as control group and other three lead acetate poisoning groups had a dose of 10,20,40 mg/kg,respectively.The poisoning was carried out by lavage once a day,and consecutively for 46 days.Eyeballs of mice were picked then for blood sampling,and BS trace element analysis grapher was used to determine level of lead,zinc,copper and iron.Level of calcium was measured by Dimentional-RXL auto-biochemistry analysis meter.Results The lead and zinc levels in poisoned mice blood were increased with increasing lead acetate level administration,while zinc level changed inversely with lead acetate level.Significant differences were shown among control group and poisoning groups in terms of lead(P0.05).Conclusion Lead posioning can lead to zinc decreasing and copper(increa)-sing,which suggests that zinc works as a poential antidote of lead poisoning.

Objective:
To understand the relationship between mental health status and vision-related quality of life( VRQL ) of students with moderate and high myopia, and to provide basis for the optimization of VRQL.
Methods:
Using convenient sampling method, the 8-18 years old students with moderate and high myopia were selected from Sichuan, Chongqing and Zhejiang. The mental health status and VRQL of students with moderate and high myopia were evaluated with Hospital Anxiety and Depression Scale and Quality of Life Scale for Ametropia. The multiple linear regression model was used to analyze the influencing factors for VRQL.
Results:
A total of 360 questionnaires were sent out and 354 were effectively recovered, with an effective rate of 98.33%. There were 116 ( 32.77% ) boys and 238 ( 67.23% ) girls; the median age was 16.65 years old. There were 211 ( 59.60% ) cases of moderate myopia and 143 (40.40%) cases of high myopia.There were 141 ( 39.83% ) found to be anxious and 176 ( 49.72% ) depressed. The median score of Quality of Life Scale for Ametropia was 64. The results of multiple linear regression analysis showed that sex ( β'= -0.179 ), diopter ( β'= 0.208 ), eyesight with glasses ( β'= -0.229 ) and anxiety ( β'= 0.439 ) were influencing factors for VRQL.
Conclusion
The mental health problems of the students with medium and high myopia are prominent; anxiety has a significant impact on the VRQL of the students.

Objective To investigate the effects of radix salviae militiorrhizae (RSM) on acute lung injury induced by"two hits"and to study its probable mechanism.Method Thirty Wister rats were randomly divided into three groups:namely normal control group,model group and RSM treatment group.The model was created by"two-hits"in which 0.2 ml/kg oleic acid was injected into tail vein first,and then 2 mg/kg lipopolysaccharide was administered four hours later.After model rats sacrificed,the pathological changes of lung were observed,and lung wet/dry weight ratio,protein content,and the ratio of neutrophiles in brochoalveolar lavage fluid (BALF) were calculated.In addition,the expression of Fas,FasL protein and apoptosis were evaluated by immunohistochemical studies and TUNEL technique.Results The acute lung injury rat model was successfully induced by"two hits".The gross and micrographic injury of lung was milder in RSM treatment rats than in model rats.The W/D ratio,protein contents and the ratio of neutrophiles in BALF were also markedly reduced in comparison with model rats,while the expression of Fas and Fasl,and the apoptosis index in model rats were significantly increased compared with other two groups.Furthermore,it showed a positive correlation between the expression of Fas,FasL,and the number of cell with apoptosis.Conclusions RSM shows a protective effect on ALT rats caused by"two hits"likely reaulted from inhibiting the expressions of Fas and Fasl,which are associated with the cell apoptosis of lung tissue.
