ABSTRACT
Objective@#To examine the impact of physical intelligence teaching on the function of children s sensory integration, so as to provide reference for promoting the development of sensory integration system.@*Methods@#From February to May 2023, the intervention was implemented for 12 weeks among 136 children aged 4-5 (68 in the intervention group and 68 in the control group). The intervention group received situational and game based physical intelligence teaching, the control group received sports game teaching according to the original curriculum objectives of the kindergarten. Intervention was administered 3 times a week for 40 minutes each time. The sensory integration ability of the intervention group and the control group were evaluated before and after the intervention with Chi square test and t test.@*Results@#The vestibular sensation, proprioception and tactile sensation of between boys and girls in the intervention group were significantly improved compared with before intervention (boys：44.14±11.52 vs. 53.34± 9.49 ，44.57±12.76 vs. 50.54±11.86，49.31±12.18 vs. 55.00±10.24,girls：46.00±11.01 vs. 54.58±10.06，48.79±13.17 vs. 53.64±11.97，52.67±11.67 vs. 56.91±10.42, t =-3.24，-2.49，-2.09，-5.24，-12.94，-2.56， P <0.05). There was no significant difference in vestibular sensation between boys and girls in the control group (boys：45.91±11.66 vs. 46.31± 11.20，girls：48.27±13.56 vs. 48.45 ±13.54, t =-0.87，-0.07， P >0.05), but there was a significant improvement in proprioception and tactile sensation in both boys and girls (boys：46.63±11.76 vs. 48.06±11.69，51.63±11.98 vs. 52.40±12.18，girls：50.45±12.16 vs. 51.67± 12.03 ，53.36±12.48 vs. 54.39±12.57， t =-3.36，-2.08，-4.66，-2.86， P <0.05). After the intervention, compared with the control group, the vestibular sensation of both boys and girls significantly improved ( t=2.83, 2.08, P <0.05), with exception of proprioception and tactile sensation ( t =0.88,0.67,0.97,0.88, P >0.05). In the experimental group, the number of normal boys increased from 12 to 24, while the number of dysfunctional boys decreased from 23 to 11, with a statistically significant difference ( χ 2=11.53, P <0.01). There was no statistically significant difference in sensory integration in boys of the control group before and after the experiment ( χ 2= 1.10 , P >0.05). After intervention,the number of normal girls in the experimental group increased from 15 to 27, while the number of dysfunctional girls decreased from 18 to 6, with a statistically significant difference ( χ 2=10.39, P < 0.05 ). There was no statistically significant difference in sensory integration in girls from the control group before and after the experiment ( χ 2=2.08, P > 0.05 ).@*Conclusion@#Physical intelligence teaching can effectively improve children s sensory integration ability, especially for vestibular function.
ABSTRACT
Objective To detect the expressions of two protein factors hypoxia-inducible factor (HIF)-1α and Helicobacter pylori (Hp) in gastric cancer in Mongolian and Han two nationalities respectively,and to explore the relationship of HIF-1α and Hp in the development of gastric cancer.Methods A modified Warthin-Starry (W-S) silver staining method was used to detect Hp infection in 27 Mongolian patients with gastric cancer and 30 Han patients with gastric cancer.Immunohistochemical (S-P) method and reverse transcription polymerase chain reaction (RT-PCR) method were used to detect protein and mRNA expressions of HIF-1α in cancer tissue,paracancerous tissue and normal tissue samples.The relationship of HIF-1α protein and Hp expression was analyzed between gastric carcinoma tissue samples of Mongolian patient group and Han patient group.Results Hp infection rates were 81.5％ (22/27) and 66.7％ (20/30) in Mongolian and Han patients with gastric cancer.The difference in infection rate was not statistically significant between two groups of patients (~=1.608,P ＞ 0.05).The positive expression levels of HIF-1α protein were 62.96％ (17/27) and 70.00％ (21/30) in gastric cancer tissue samples of Mongolian and Han groups.The relative expression levels of HIF-1α mRNA were 0.891 4±0.075 0 and 0.907 4±0.065 5.There was no significant difference in the HIF-1 α mRNA expression between the two nationalities.No positive expressions of HIF-1α protein and mRNA were found in paracancerous tissue and normal tissue samples.There was a positive correlation in the positive expression of HIF-1α protein and Hp infection in gastric cancer tissue samples of Mongolian and Han patient groups (r,=0.424 and 0.617,P ＜ 0.05).Conclusion HIF-1α and Hp are pathogenic factors of gastric cancer.Hp and HIF-1α may promote the occurrence of gastric cancer together.The pathogenic mechanism of HIF-1α and Hp in gastric cancer may be the same for Mongolian and Han patients.
