Objective To investigate the effectiveness of transtheoretical model of behavior change in the intervention of childhood obesity. Methods Randomized sampling method was used to select experiment schools and control schools for physical examination from October 2012 to June 2014. The overweight and obesity students of the experiment schools were intervened with the transtheoretical model of behavior change. The authors evaluated the obesity students′ knowledge about the intervention of obesity, healthy behavior methods compliance, and weight control qualified rate. Results Before the intervention, the obesity rate, BMI of overweight students, skinfold thickness, blood glucose and blood lipid had no significant differences between the two groups (P>0. 05). After the intervention, the BMI and skinfold thickness in the experiment group were (27. 7 ± 3. 6) kg/m2 and (21. 7 ± 4. 3)mm, which were significantly better than those in the control group (t=3. 674, 4. 029, respectively;P<0. 05). The blood glucose, total cholesterol, triglyceride,high and low density lipoprotein in the experiment group were(5. 17 ± 0. 8), (3. 47 ± 0. 6), (0. 73 ± 0. 3), (1. 14 ± 0. 1) and (1. 53 ± 0. 2) respectively, which were significantly better than those in the control group ( t=3. 437, 4. 257, 3. 478, 2. 206,3. 759, respectively;P <0. 05). The knowledge of obesity, healthy behavior adherence and weight control rate in the experiment group were significantly better than those in the control group (P<0. 05). Conclusions The application of tanstheoretical model of behavior change for nursing intervention and prevention has a prosperous future for getting the overweight and obesity student to have more knowledge about obesity, enhance the healthy behavior methods compliance, and increase the rate of weight qualified.

Objective To estimate the curative effect of non-gastrointestinal decompression in laproscopic colorectal surgery. Methods By using the single-blind-random test and prospective study, 55 patients were divided into two groups, experimental group and matched group. The difference of operating time, gastrointestinal function recovery time, adverse effect, complication, average length of hospital stay between two groups were observed and evaluated. Results The difference of operating time, gastrointestinal function recovery time, adverse effect, complication, average length of hospital stay between two groups were not statistically significant(P>0.05). The incidence rate of sore throat and cough and expectoration difficulty after operation was significantly lower in the experimental group (the rate was respectively 16.0% vs 77.7% and 8.0% vs 50.0, P<0.05). However, The incidence rate of nausea and vomiting, abdom-inal distension was not statistically significant(P>0.05). Conclusion In the perioperative period of laproscopic colorectal surgery, non-gastrointestinal decompression appears to be security and feasible.
