Objective To translate the Water Orientation Test of Alyn 1 (WOTA1) into Chinese and investigate the test-retest reliability, inter-rater reliability and validity of this Chinese Version. Methods The Water Orientation Test of Alyn 1 was translated from English into Chinese. 25 children with cerebral palsy were tested with Chinese Version of WOTA1 by 2 raters. One of the raters accessed the same children again after 2 days. While the children were assessed with Brief Assessment of Motor Function (BAMF). The scores from both raters, twice of one rater, and of WOTA1 and of BAMF were analyzed with Pearson correlation coefficient. Results The correlation coefficient of test-retest of WOTA1 total score is 0.992 (95% CI: 0.982-0.996), and it was 0.887 to 1.000 of the scores of items. The correlation coefficient of inter-rater of total score is 0.992 (95% CI: 0.980-0.998), and it was 0.748 to 1.000 of the scores of items. The correlation coefficient between scores of WOTA1 and BAMF was 0.926 (P<0.01). Conclusion The Chinese Version of WOTA1 is good reliable and valid to assess the motor function in hydrotherapy pool.

Objective To evaluate the effect of microRNA-182-5p (miR-182-5p) on proliferation and apoptosis of non-small cell lung cancer (NSCLC) A549 cells by targeting forkhead box O3a (FOXO3a).Methods The difference of miR-182-Sp expression between human normal lung epithelial cells BEAS-2B and NSCLC cells A549 was compared.The A549 cells were chosen,and miR-182-Sp mimic (miR-182-Sp mimic group),miR-182-Sp inhibitor (miR-182-5p inhibitor group),negative control mimic (NC mimic group) and negative control inhibitor (NC inhibitor group) were transfected respectively.The expression of miR-182-Sp was detected by reverse transcription-polymerase chain reaction (RT-PCR).The protein expression of FOXO3a was detected by Western blotting.The cell proliferation activity was detected by methyl thiazolyl tetrazolium (MTT) method.The cell apoptosis was detected by flow cytometry.The targeted relationship between miR-182-5p and FOXO3a was detected by dual-luciferase experiment.Results The miR-182-5p expression of A549 cells and BEASo2B cells respectively was 3.21 ±0.24 and 1.01 ±0.11,and the difference was statistically significant (t =14.209,P＜0.001).The miR-182-5p expression of NC mimic group,miR-182-5p mimic group,NC inhibitor group and miR-182-5p inhibitor group respectively was 1.09 ± 0.20,12.80 ± 1.10,1.03 ± 0.11and 0.47 ± 0.08,and the difference was statistically significant (F =87.872,P ＜ 0.001).The FOXO3a expression of the above four groups respectively was 118.34 ± 16.71,50.89 ± 11.58,125.33 ± 20.87 and 289.26 ± 34.51,and the difference was statistically significant (F =62.125,P ＜ 0.001).The 72 h proliferation activity of the four groups respectively was 1.12 ± 0.13,1.70 ± 0.14,1.07 ± 0.13 and 0.71 ± 0.11,and the difference was statistically significant (F =31.336,P ＜ 0.001).The proliferation activity of miR-182-5p mimic group was significantly higher than that of NC mimic group (P ＜ 0.05),and the proliferation activity of miR-182-5p inhibitor group was significantly lower than that of NC inhibitor group (P ＜0.05).The apoptosis rate of the four groups respectively was (5.51 t±1.80)％,(1.41 ±0.50)％,(6.24 ± 1.71)％ and (47.93 ± 5.12) ％,and the difference was statistically significant (F =211.081,P ＜ 0.001).The apoptosis rate of miR-182-5p mimic group was significantly lower than that of NC mimic group (P ＜ 0.05),and the apoptosis rate of miR-182-5p inhibitor group was significantly higher than that of NC inhibitor group (P ＜0.001).The miRNA target genes prediction software test results showed that miR-182-5p could act on FOXO3a 3' untranslated region (UTR).Compared with transfection NC mimic,co-transfection miR-182-5p mimic and FOXO3a-Wt could make luciferase activity of A549 significantly decreased (1.20 ±0.14 vs.0.62 ±0.10;t =5.839,P =0.004).Conclusion miR-182-5p can enhance proliferation and inhibit apoptosis of A549 cell by targeting FOXO3a.

Objective To observe the effects of Traditional Chinese Medicine bubble bath on the children with spastic diplegia cerebral palsy. Methods 13 children with spastic diplegia cerebral palsy received routine rehabilitation and bubble bath (control group), while 14 children received routine rehabilitation and Traditional Chinese Medicine bubble bath (experimental group). All the children were assessed with Gross Motor Function Measure (GMFM-66) and Modified Ashworth Scale (MAS) of triceps surae muscle before and 10 weeks after treatment.Results The total score of GMFM-66 increased (P<0.001) and the MAS score decreased in both groups (P<0.01) after treatment. The dimensions B, D, and E of GMFM-66 only increased in the experimental group (P<0.05). The MAS score decreased more in the experimental group than in the control group after treatment (P<0.05). Conclusion Traditional Chinese Medicine bubble bath can improve gross motor function and reduce triceps surae muscle tension of the children with spastic diplegia cerebral palsy.

Objective To translate the Water Orientation Test of Alyn 2 (WOTA2) into Chinese, and to study its reliability and validity for patients with spinal cord injury. Methods After authorizing, the English version WOTA2 scale and its training package were translated into Chinese. From January to September, 2018, 137 patients with spinal cord injury were evaluated with the Chinese version WOTA2 by two evaluators independently, and evaluated again three days later by one of the evaluators. The Cronbach's α, Spearman-Brown coefficient, intra-group correlation coefficient (ICC) and Kappa coefficient were calculated to evaluate the reliability. Content Validity Index (CVI) of items (I-CVI) and scale (S-CVI) were used to evaluate the content validity, and factors analysis was used to evaluate the structure validity. Results The Cronbach's α was 0.947 in all items of the scale, 0.890 in mental adjustment items and 0.954 in aquatic skills items. Pearson correlation coefficient of the half scales separated by odd and even items was 0.948, and the Spearman-Brown coefficient was 0.973. The ICC of test-retest was 0.965 in total score, 0.965 in centesimal system total score, 0.847 in mental adjustment score and 0.970 in aquatic skills score. The ICC of inter-testers was 0.964 in total score, 0.965 in centesimal system total score, 0.847 in mental adjustment score and 0.970 in aquatic skills score. The Kappa coefficient was 0.528 to 0.927 in test-retest and 0.528 to 0.927 in inter-testers. The I-CVI was 0.8 to 1.0 and S-CVI was 0.63. Factors analysis extracted four factors, which met the theory, and contributed 67% of cumulative variance. Conclusion The Chinese version WOTA2 is good in reliability and validity for patients with spinal cord injury, and can be used in the clinical practice of aquatic therapeutic exercise in China.
