Minimal clinically significant difference for postoperative VAS between groups was accepted as one (estimated standard deviation was 1,5). Cohen's d was 0,66 and the minimum number of patients for each groups was 38 for 80% power. Nonparametric variables of the patients were expressed as a percentage, and parametric variables were expressed as mean ± standard deviation. The normal distribution was assessed by the Kolmogorov-Smirnov test. When comparing groups, independent-sample t-test was used when the distribution was normal, while when it was not normal Mann–Whitney U test was used. The χ² test was used to compare the nonparametric data of the groups. Fisher's exact test was preferred when the nonparametric variables were below 5 during the comparisons. For evaluating effects of the operation on the SF-36 quality of life index, when the distribution was normal the paired-sample t-test was used; otherwise Wilcoxon Rank Sum test was used. A value of p < 0.05 was considered statistically significant. All analyses were performed using the SPSS 15.0 program for Windows (SPSS Inc., Chicago, IL, USA).

All analyses were performed using the SPSS 15.0 program for Windows software package (SPSSInc., IL, USA). Statistical significance between groups within experiments was determined using the one-way analysis and Student t test. The chi-square test was used to determine whether two groups had distinct gene expression levels. The Spearman’s rank correlation test was used to determine the correlations between LIMK1 and destrin. The survival was estimated using the Kaplan–Meier method and compared using the log-rank test. A P value of < 0.05 was considered statistically significant.
