ObjectiveTo analyze the reliability and validity of Chinese version of Dysarthria Impact Profile (DIP) in assessment of the psychosocial impact of dysarthria in Parkinson's disease (PD). MethodsFrom May, 2021 to March, 2022, 43 PD patients from Department of Rehabilitation Medicine, the First Affiliated Hospital of Sun Yat-sen University were selected, and 43 age matched healthy controls were enrolled. The process of translation and adaptation was used to develop the Chinese version of DIP, and two groups were evaluated. The internal consistency reliability and intra-rater reliability were analyzed as well as the correlation between each item and its subscale, DIP scores to the Voice Handicap Index (VHI) and 36-item Short Form Health Survey (SF-36). DIP scores of two groups were compared. ResultsThe Cronbach's α was 0.732 to 0.942. The intra-rater correlation coefficient of subsection four was the highest (r = 0.670, P < 0.001). The correlation coefficients were 0.315 to 0.871, which were correlated (P < 0.05), except items 1, 6, 11 of subsection three and item 11 of subsection four. The correlation coefficient between DIP and VHI was -0.821 (P < 0.01), and it was 0.684 (P < 0.01) between DIP and SF-36. DIP scores were significant different between PD patients and the control group (P < 0.01). ConclusionThe Chinese version of DIP shows good reliability and validity, and can be used as a tool to measure the psychosocial impact of dysarthria in PD patients.

Objective:To investigate the vitamin D level of pulmonary tuberculosis patients in Qinghai Province, and to explore the correlation between vitamin D level and pulmonary tuberculosis.Methods:From May to September 2020, 208 bacterial confirmed pulmonary tuberculosis patients who were admitted to The 4th People′s Hospital of Qinghai Province were enrolled as the pulmonary tuberculosis group, and 129 healthy people who underwent physical examination during the same period were enrolled as the healthy control group. Independent sample t test and chi-square test were used for statistical analysis. Results:The deficiency rate of vitamin D was 11.06%(23/208) in the pulmonary tuberculosis group, which was higher than that (3.10%(4/129)) in the healthy control group, and the difference was statistically significant ( χ2=6.840, P=0.009). The vitamin D level was (56.84±20.03) μg/L in the pulmonary tuberculosis group, which was lower than that ((67.39±17.07) μg/L) in the healthy control group, and the difference was statistically significant ( t=5.154, P<0.01). The vitamin D levels were not different between the newly treated ((56.66±20.02) μg/L)) and retreated pulmonary tuberculosis patients ((59.11±20.81) μg/L) ( t=0.468, P=0.650). The vitamin D level of simple pulmonary tuberculosis patients ((57.82±20.01) μg/L) was higher than that of pulmonary tuberculosis patients combined with other diseases ((48.08±18.46) μg/L), and the difference was statistically significant ( t=2.132, P=0.034). Conclusion:Pulmonary tuberculosis is associated with decreased vitamin D levels, and patients with pulmonary tuberculosis are more likely to suffer from decreased or deficient vitamin D, which suggests clinicians considering the vitamin D status when treating pulmonary tuberculosis patients.

Objective:To investigate the effect of Lee Silverman voice therapy (LSVT) on the speech and life quality of Chinese persons with Parkinson′s disease (PD).Methods:A total of 16 Chinese PD patients were enrolled and given standard LSVT for 4 weeks. Their acoustic data were analyzed using PRAAT software before and after the treatment. Their voice quality was evaluated using the Japanese GRBAS voice scale and their quality of life was quantified using the Voice Handicap Index (VHI) scale.Results:After 4 weeks of LSVT the patients′ average voice and life quality had improved significantly. The average maximum duration of sustained vowel phonation had increased significantly, as had the vowels′ mean loudness, reading and monologue delivery. The GRBAS grading indicated that hoarseness had decreased significantly. The average total voice handicap index had also decreased significantly.Conclusion:Lee Silverman therapy can significantly improve maximum phonation time and loudness of Chinese-speakers, which enhances sensory feedback. The quality of their speech and of their life also improve significantly. This technique is recommended for clinical application.

@#Objective To investigate the neural mechanisms of speech motor control in individuals with Parkinson's disease (PD) under different strategies of motor execution control.MethodsThe techniques of the psychoacoustic and event-related potentials (ERPs) based on the altered auditory feedback paradigm were used in the present study. Two groups, including 17 PD patients and 17 healthy controls, were instructed to produce sustained vowels under the internal and external cueing tasks while hearing their voice randomly pitch-shifted downwards. The vocal responses and associated ERPs were recorded and compared across the groups and tasks.ResultsBehavioral results showed that the amplitude of acoustic compensation response was larger in PD patients than in the healthy controls (F=5.415, P=0.027), however, the main effect was not significant in the tasks (F=0.039, P=0.840). At the cortical level, PD patients produced significantly larger N1 responses to pitch perturbations in the internal cueing task related to the external cueing task (F=8.634, P=0.006), while such task effect was not observed in the healthy controls (F=1.550, P=0.231). Also, PD patients produced significantly larger N1 responses than the healthy controls in the internal cueing condition (F=5.476, P=0.026), but not in the external cueing condition (F=0.249, P=0.621). Conclusion Speech motor control in PD can be influenced by the strategies of motor execution control. Compared to the internal cueing task, the external cueing task can increase neural efficiency in the encoding of speech auditory feedback PD patients that improve auditory-motor integration for speech production.

Objective To evaluate the damaged level of auditory processing and diagnose the type of language impairment in an audito-ry agnosia patient using Psycholinguistic Assessment in Chinese Aphasia (PACA), and predict the outcome of the language function. Meth-ods A patient with a bilateral damage involving the temporal lobe could physically hear the sounds, but was unable to recognize or differenti-ate between the sounds. Speech and language evaluations were taken with PACA 4 weeks, 8 weeks and 3 months after the onset of disease. Results At 4 weeks, the correct rates were 2.5%and 95.0%in spoken word-picture matching and written word-picture matching (P<0.001), and were 5.6%and 80.6%in spoken semantic knowledge and written semantic knowledge (P<0.001). The scores of auditory input process-ing function score were low, including phoneme discrimination, spoken word matching with minimal differences, environmental sounds identification. The correct rates were 67.5%in oral picture naming, 0 in word repetition, 70.0%in word reading, 0 in dictation, 100.0%in di-rectly copy writing. At 8 weeks and 3 months, there was complete recovery in written word-picture matching (both 100%) and written se-mantic knowledge (97.2%, 100%), and improvement in oral picture naming (87.5%, 90%), word repetition (87.5%, 97.5%), picture name writing (77.5%, 87.5%) and copy writing (both 100%) (P<0.05). But no change was found in auditory input processing function examina-tions, spoken word-picture matching (5.0%, 7.5%), spoken semantic knowledge (2.8%, 5.6%), word repetition (0, 3.3%) and dictation (both 0). Conclusion The patient was diagnosed as auditory agnosia with the inability to distinguish sounds. PACA can well identify the impaired level of auditory comprehension disorder and the outcome of language function recovery for aphasics.

Objective: To investigate influence of isometric exercise (IE) training on number of endothelial progenitor cells (EPCs) and level of vascular endothelial growth factor (VEGF) of circulating blood in patients with coronary chronic total occlusion (CTO). Methods: A total of 20 CTO patients were divided into training group (n=10) and control group (n=10). Both groups received routine medication for three months, training group also received three-month IE training (maximal handgrip was used to induce maximum IE of upper limb muscles, leading to temporary physiological ischemia of skeletal muscle),while control group remained sedentary without exercise training. Flow cytometry was used to measure number of blood EPCs, and enzyme linked immunosorbent assay (ELISA) was used to measure serum concentration of VEGF. Results: Before treatment, the differences of levels of blood EPCs and VEGF between two groups were no significant(P>0.05). Compared with before treatment, there were significant increase in blood number of EPCs [(0.028±0.009)% vs. (0.044±0.016)%] and VEGF concentration [(65.3±15.1) pg/ml vs. (98.5±17.4)pg/ml] after three-month treatment in training group (P=0.015, P0.05. The blood numbers of EPCs were positively correlated with VEGF concentration in training group and control group (r=0.727, r=0.785, P<0.05 both). Conclusions: Isometric exercise training can increase blood number of EPCs and VEGF concentration in coronary CTO patients, which may contribute to collateral angiogenesis in remote ischemic myocardium.
