Objective To investigate the diagnostic value of masseter muscle thickness fraction(MMTF)measured by ultrasound for the occurrence of dysphagia in patients with Parkinson's disease(PD).Methods A total of 100 patients were selected as the study group,and another 50 healthy individuals who received medical checkups with matched age,gender and body mass index(BMI)in our hospital during the same period were selected as the control group.The demographic data and disease characteristics of PD patients were recorded,and patients were divided into the dysphagia group(n=34)and the non-dysphagia group(n=66)according to the occurrence of dysphagia.The demographic data,and disease characteristics such as Hoehn-Yahr(H&Y)stage,Unified Parkinson's Disease Rating Scale(UPDRS)Ⅲ score,levodopa equivalent daily dose(LEDD)and MMT-related parameters measured by ultrasound were compared between the two groups.The indicators with P＜0.05 in univariate analysis were used as independent variables,and the influencing factors of dysphagia in patients with PD were investigated by binary Logistic regression analysis.The diagnostic efficacy of each index for dysphagia in patients with PD was evaluated by constructing receiver operating characteristic(ROC)curves,and the area under the curve(AUC)was calculated.Results The MMT during forceful biting and MMTF were lower in the study group than those in the control group(all P＜0.05).Compared with the non-dysphagia group,the dysphagia group was older and had higher H&Y stage and UPDRS III scores(all P＜0.05).The MMT during forceful biting and MMTF in the dysphagia group were lower than those in the non-dysphagia group(all P＜0.05).Multivariate Logistic regression analysis showed that increased UPDRSⅢ score was the risk factor for dysphagia in patients with PD,and increased MMT during forceful biting and MMTF were protective factors.The ROC curve analysis indicated that the AUC(95%CI)of UPDRS Ⅲ score,MMT during forceful biting and MMTF for diagnosing dysphagia in patients with PD were 0.714(0.615-0.800),0.744(0.647-0.826)and 0.888(0.809-0.942),respectively.The AUC of MMTF for diagnosing dysphagia in patients with PD was higher than those of UPDRS Ⅲscores and MMT during forceful biting(Z values were 2.611 and 2.208,respectively,P＜0.05).Conclusion MMTF is an independent influencing factor for dysphagia in patients with PD and can be used as a screening indicator for dysphagic patients.

Objective:To summarize and compare the characteristics of orthostatic hypotension (OH)　in　patients　with　Parkinson′s disease and multiple system atrophy (MSA).Methods:The active standing test data of 210 Parkinson′s disease patients (Parkinson′s disease group) and 85 MSA patients (MSA group) admitted to the Department of Neurology, Xuanwu Hospital, Capital Medical University from January 2021 to March 2022 were retrospectively analyzed. Demographic information, clinical data, Hoehn-Yahr staging, and Unified Parkinson′s Disease Rating Scale (UPDRS), Non-Motor Symptoms Questionnaire (NMSQ), Montreal Cognitive Assessment Scale and Mini-Mental State Examination scores were collected. The comparative analysis of OH was conducted according to the changes of heart rate and blood pressure during the active standing test.Results:Among the 85 patients with MSA, 52 were found with MSA parkinsonism variant (MSA-P) and 33 with MSA cerebellar variant (MSA-C). The 210 Parkinson′s disease patients were aged (61.5±11.0) years, with 116 males (55.2%). The 85　MSA　patients　were aged (60.1±6.8) years, with 44 males (51.8%). Compared with the Parkinson′s disease group, the Hoehn-Yahr staging [2.0(2.0, 3.0) vs 3.0(2.0, 3.0), Z=-5.278, P<0.001], NMSQ[ 25.0(11.0,46.5) vs 45.0(24.0,70.0), Z=-3.632, P<0.001] and UPDRS scores [50.0(32.0,68.0) vs 65.5(44.5,78.5), Z=-3.073, P=0.003] in the MSA group were higher. The incidence of OH in the MSA group was higher than that in the Parkinson′s disease group [63.5% (54/85) vs 25.7%(54/210), χ 2= 37.284, P<0.001], but there was no statistically significant difference between the MSA-P and MSA-C groups . Compared with the Parkinson′s disease group, the MSA group had a higher incidence of classical OH [54.1%(46/85) vs 12.9%(27/210), χ 2=55.316, P<0.001] and neurogenic OH [36.5%(31/85) vs 9.0%(19/210), χ 2=32.326, P<0.001],but there was no statistically significant difference in the incidence of initial OH and delayed OH between the two groups. The incidence of severe OH in the MSA group was also higher than that in the Parkinson′s disease group [57.6%(49/85) vs 16.7%(35/210), χ 2=49.894, P<0.001], but there was no statistically significant difference in the incidence of pre-clinical OH and mild OH between the two groups. Conclusions:The incidence, time change, severity and pathophysiological basis of OH in Parkinson′s disease and MSA patients are different. Different types of OH may help to distinguish MSA from Parkinson′s disease.

Objective:To evaluate the clinical value of four dimensional ultrasound combined with pelvic floor surface electromyography in the assessment of bladder prolapse in primipara with different delivery modes.Methods:A total of 413 primipara 6-8 weeks after full-term delivery were selected from the obstetrics clinic of the Second Affiliated Hospital of Hainan Medical College from October 2021 to September 2023. They were divided into natural delivery group(349 cases) and cesarean section group(64 cases ). The characteristics of 4D pelvic floor ultrasound in the two groups were analyzed and summarized. Then 64 cases of primipara with pelvic floor surface electromyography were divided into bladder prolapse group (46 cases) and no bladder prolapse group(18 cases). The characteristics of four dimension ultrasound combined with pelvic floor surface electromyography in the two groups were analyzed, and the related risk factors of bladder prolapse were analyzed.Results:The bladder neck mobility and urethral rotation angle in the natural delivery group were higher than those in the cesarean section group (all P<0.05). Compared with the cesarean section group, the incidence of obvious prolapse and urethral infundibulation was higher in the natural delivery group, while the incidence of mild prolapse was lower than that in the cesarean section group (all P<0.05). Bladder neck mobility, urethral rotation angle and levator ani hiatal area in the prolapsed bladder group were higher than those in the non-prolapsed bladder group (all P<0.05). The maximum value of fast muscle stage and the mean value of slow muscle stage in the group with prolapse were lower than those in the group without prolapse (both P<0.05). Univariate Logistic regression analysis found that the risk factors for bladder prolapse were increased birth weight, natural delivery, increased bladder neck mobility, posterior bladder angle was opened, increased urethral rotation angle, increased levator ani hiatal area, decreased maximum value of fast muscle stage and decreased mean value of slow muscle stage. Multivariate Logistic regression analysis showed that increased ani hiatal area ( OR=2.216, P=0.015) and decreased maximum value of tater muscle stage ( OR=0.847, P=0.035) were risk factors for bladder prolapse. Conclusions:Pelvic floor ultrasound combine with pelvic floor surface electromyography can qualitatively and quantitatively evaluate the changes of pelvic floor muscle structure and function in postpartum women, and diagnose bladder prolapse and its degree. The increase of levator ani hiatal area and the decrease of maximum value of tater stage may be the risk factors for bladder prolapse at 6-8 weeks postpartum in primiparas.

Objective: To evaluate the interventional effects of music therapy on pain and anxiety of burn patients in wound dressing change. Methods: The meta-analysis method was adopted. Databases including China National Knowledge Internet, Wanfang Database, and VIP database were retrieved with the search terms in Chinese version of ", , /, /", and PubMed, Embase, and Cochrane Library were retrieved with the search terms in English version of "music, burn, dressing change/wound dressing, pain/ache/sore" to obtain the publicly published randomized controlled trials on the application of music therapy for wound dressing change in burn patients from the establishment of each database to May 2021. The outcome indexes included pain score/percentage and anxiety score after dressing change. Rev Man 5.4 and Stata 14.0 statistical software were used to conduct a meta-analysis of eligible studies. Results: A total of 520 burn patients from 7 studies were included, including 260 patients in music therapy group who received music therapy and 260 patients in routine dressing change group who received routine dressing change. The bias risk of all the 7 included studies was uncertain. Compared with those in routine dressing change group, the pain percentages (relative risk=0.06, 95% confidence interval=0.01-0.41, P<0.01) and pain scores after dressing change (standardized mean difference (SMD)=-0.91, 95% confidence interval=-1.61--0.22, P<0.05) of patients in music therapy group were significantly lower. Subgroup analysis showed that music type and timing of intervention might be the source of heterogeneity in pain scores after dressing change. The anxiety scores of patients in music therapy group were significantly lower than those in routine dressing change group (SMD=-0.64, 95% confidence interval=-1.09--0.19, P<0.01). There was no publication bias in pain or anxiety scores after dressing change. Conclusions: Music therapy can relieve the pain and anxiety of burn patients during dressing change.
