ABSTRACT
Objective To explore the effects of the mouth -muscle strengthening training on the phonetic in-telligibility (PI) of children with functional articulation disorders (FAD) .Methods A total of 80 children of 4 to 7 years old with FAD were randomly divided into the common group (n=40) and comprehensive group (n=40) .Both groups accepted routine speech training ,and the comprehensive group was given mouth muscles training additional-ly .All the children received the assessment of speech before the speech training and 3 months after the training .Re-sults Before the speech training ,the PIs of the common and comprehensive groups were 34 .54％ and 33 .52％ ,re-spectively .The differences between the 2 groups were not statistically significant (P> 0 .05) .After 3 months of speech training ,the PI in the common group increased to 77 .02 ± 4 .21％ from 34 .54 ± 7 .28％ of the baseline ,while in the comprehensive group ,the PI increased to 87 .54 ± 4 .31％ from 33 .52 ± 7 .46％ .In both groups ,the PIs after training were significantly higher than those of before the training respectively .The differences were statistically significant (P<0 .05) .The PIs in the comprehensive group were significantly higher than those of in the common group .The differences were statistically significant (t= -8 .862 ,P<0 .001) .Conclusion Strengthening the mouth muscles is beneficial to improve the PI of children with FAD .
ABSTRACT
@#Objective To investigate the effect of Santong electroacupuncture (EA) on mRNA and protein expression of p75 neurotroph-in receptor (p75NTR) in rats with spinal cord injury (SCI). Methods A total of 72 female Sprague-Dawley rats were randomly assigned to sham operation group (group A, n=8) and model group (n=64). In the model group, Allen's method was used to make SCI rats model, in which 48 survived model rats were further subdivided into model control group (group B, n=12), EA group (group C, n=12), inhibitor Nogo extra cellular peptide residues 1-40 (NEP1-40) group (group D, n=12) and EA+inhibitor NEP1-40 group (group E, n=12) according to de-sign proposal. The treatment groups were electroacupunctured on Dazhui (GV14) and Yaoyangguan (GV3), bilateral Ciliao (BL32) and Zu-sanli (ST36) with loose-tight wave, for 20 minutes every day. After 7 and 14 days of treatment, injured spinal cord tissue was extracted for detecting. The mRNA and protein expression of p75NTR was detected by real-time fluorescent quantitative PCR, in situ hybridization and Western blotting respectively. The hind limb motor function was assessed with Basso-Beattie-Bresnahan (BBB) score. Results The BBB score increased in the treatment groups compared with group B, and was higher in group E than in groups C and D (P<0.05), as well as on the 14th day than on the 7th day in all the treatment groups (t>2.623, P<0.05). The mRNA and protein expression of p75NTR in spinal cord tissues decreased in the treatment groups compared with group B (P<0.05), and no significant difference was found among the treatment groups (P>0.05). Conclusion Santong elerctroacupuncture treatment could improve the hind limb motor function, which may associate with inhibition of the mRNA and protein expression of p75NTR in rats after SCI.
ABSTRACT
Objective To study the phonetic characteristics of patients with abnormal plosive consonant of functional articulation disorders (FAD) and the possible treatment approaches.Methods A total of patients of 4~26 years old with abnormal plosive consonant of FAD received speech assessment and the phonetic characteristics.Incorrect articulation patterns and forms of plosive consonant /b/,/p/,/d/,/t/,/g/ and /k/ were analysed.The targeted speech treatment was established to correct the erroneous places and types of pronunciation.Results The error rate of /t/ (82/87)was the highest,followed by /k/(77/87),/d/(67/87),/g/(60/87),/p/(59/87) and /b/(3/87) which was the lowest.The error rate of fricative was 65.52% as the highest among all the erroneous patterns,followed by unaspiration(63.22%),forward movement of the tongue(54.02%),distortion(33.33%),bilabial(32.18%),and backward movement of the tongue(18.39%).Seventy-one cases were completely cured,and 16 cases partially cured after 2 to 10 times of treatment.The number of incorrect words of plosives decreased to 4.03±2.71 after the speech therapy from 67.97±18.56 prior to that.The differences were statistically significant (t =34.301,P<0.001).Conclusion The articulation errors of plosives occur mainly on /t/,/k/,/d/,/g/and /p/,/b/.The incorrect types of pronunciation are fricatives,unaspiration,distortion and omission.The incorrect places of articulation are forward movement of the tongue,bilabial and backward movement of the tongue.The targeted speech therapy established according to the erroneous places and types of articulation is significantly effective.
