Objective:To observe the effect of speech training based on mirror neuron theory on children with functional articulation disorder (FAD).Methods:Fifty children with FAD were randomly divided into a training group and a control group, each of 25. Both groups received 30 minutes of conventional speech training 5 times a week for 24 weeks, while the training group was additionally given 20 minutes of speech training based on mirror neuron theory simultaneously. Before and after the intervention, both groups were evaluated using the articulation speech ability assessment scale and the oral motor ability assessment scale.Results:Before the treatment, there were no significant differences between the 2 groups in any of the measurements. After the treatment, significant improvement was observed in all of the measurements for both groups, but at that point the training group′s articulation, motor ability of the lower jaw, tongue and lips were all significantly superior to the control group′s averages.Conclusions:Speech training based on mirror neuron theory can significantly improve the articulation, intelligibility and oral motor functioning of children with functional articulation disorder.

Objective:To subdivide clinical classification of refractory atlantoaxial dislocation, and evaluate the reliability of new subdivide clinical classification of refractory atlantoaxial dislocation.Methods:From January 2010 to December 2018, 48 patients with refractory atlantoaxial dislocation were treated, including 19 males and 29 females, aged 16 to 65 years, with an average of 39.2±13.3 years. According to the changes of relative anatomical position of C 1 and C 2 under general anesthesia with heavy traction of 1/6 body weight, subdivide clinical classification of refractory atlantoaxial dislocation were proposed, and refractory atlantoaxial dislocation was divided into traction loosening type (atlantoaxial angle&ge;5°) and traction stabilization type (atlantoaxial angle<5°). The traction loosening type was directly reduced by posterior atlantoaxial screw-rod fixation and fusion without anterior or posterior soft tissue release. For traction stabilization type, transoral soft tissue release was performed first, and then transoral anterior reduction plate fixation and fusion or posterior atlantoaxial screw-rod fixation and fusion were performed. Atlantodental interval (ADI) and atlantoaxial angle (AAA) were measured and collected before and after surgery to evaluate atlantoaxial reduction. The space available for the spinal cord (SAC) were measured to evaluate spinal cord compression. Visual analogue score (VAS) was used to evaluate the neck pain levels, and Japanese Orthopaedic Association (JOA) scores was used to evaluate the neurological function. American Spinal Cord Injury Association impairment scale (AIS) was used to evaluate the degree of spinal cord injury. One week, 3, 6, 12 months postoperatively and the annual review of the X-ray and CT scan were checked, in order to evaluate the reduction, internal fixation and bone graft fusion. Results:Among all 48 cases, 22 cases were traction loosening type, of which posterior atlantoaxial screw-rod fixation and fusion were performed in 16 cases and occipitocervical fixation and fusion in 6 cases. 26 cases were traction stabilization type, and they all underwent anterior transoral release, and then, anterior TARP fixation and fusion were performed in 24 cases and posterior screw-rod fixation and fusion in the other 2 cases. X-ray, CT and MRI images and of all patients 1 week after surgery showed good atlantoaxial reduction and decompression of spinal cord. In each of the two types, there was one case lost to follow-up. For 46 cases in follow-up, the follow-up time ranged from 6 to 72 months, with an average of 38.0±17.2 months. Among 46 cases, 21 cases of traction loosening type showed that, ADI reduced from preoperative 9.9±2.2 mm to 2.3±0.9 mm at 3 months after surgery and 2.3±1.0 mm at the last follow-up, AAA increased from preoperative 57.9°±12.3° to 91.0°±2.2° at 3 months after surgery and 90.9°±2.2° at the last follow-up, SAC increased from preoperative 9.8±1.3 mm to 15.1±0.7 mm at 3 months after surgery and 14.9±0.7 mm at the last follow-up, VAS score reduced from preoperative 1.5±2.1 to 0.7±1.0 at 3 months after surgery and 0.3±0.6 at the last follow-up, and JOA score increased from preoperative 10.2±1.7 to 13.3±1.3 at 3 months after surgery and 14.9±1.5 at the last follow-up. Twenty-five cases of traction stabilization type presented that, ADI reduced from preoperative 9.7±2.0 mm to 2.1±1.4 mm at 3 months after surgery and 2.1±1.3 mm at the last follow-up, AAA increased from preoperative 55.8°±9.2° to 90.9°±1.4° at 3 months after surgery and 90.9°±1.3° at the last follow-up, SAC increased from preoperative 10.5±1.0 mm to 15.4±0.5 mm at 3 months after surgery and 14.8±2.8 mm at the last follow-up, VAS score reduced from preoperative 1.7±2.1 to 0.7±0.9 at 3 months after surgery and 0.3±0.5 at the last follow-up, and JOA score increased from preoperative 10.1±1.3 to 12.9±1.5 at 3 months after surgery and 14.4±1.3 at the last follow-up. In the traction loosening type, all the 10 grade D patients were improved to grade E at the last follow-up. In the 2 grade C patients of traction stabilization type before surgery, 1 patient was improved to grade E, 1 patient was improved to grade D, and all 11 patients with grade D were improved to grade E at the last follow-up. Bony fusion was obtained in all patients from 3 to 6 months, with an average of 4.4±1.5 months. During follow-up period, no looseness of internal fixation or redislocation happened.Conclusion:Refractory atlantoaxial dislocation can be divided into traction loosening type and traction stabilization type. For traction loosening type, satisfactory reduction can be achieved by using posterior atlantoaxial screw-rod system without soft tissue release. For traction stabilization type, anterior release is preferable, and then anterior TARP or posterior screw-rod can be used to achieve satisfactory reduction.

BACKGROUND: Immune-related adverse events (irAEs) are commonly occurred in patients treated with immune checkpoint inhibitors. However, evidence of irAEs derived from the Chinese population is relatively lacking. The aim of this study was to investigate the incidence and outcomes of irAEs in Chinese patients with lung cancer after receiving immune checkpoint inhibitors (ICIs). METHODS: Clinical and follow-up data from lung cancer patients who received at least one time of ICIs from January 2018 to September 2021 at Huadong Hospital, Fudan University were included. Statistical descriptions and Kaplan-Meier method were used to analyze the overall incidence of irAEs, as well as the incidence and outcomes of each type of irAEs. RESULTS: 135 patients were included in the study. 106 patients (78.5%) presented at least one type of irAEs, and the median time to first irAEs onset was 28 d. Most irAEs occurred at early time after treatment, and most irAEs were mild-moderate and reversible. 57 patients (42.2%) died at the study cutoff. The mortality rate of severe irAEs was 12.6% (n=17), and among them 7 patients (41.2%) died of pneumonitis. The median progression-free survival (PFS) and overall survival (OS) time of the total population was 505 d (95%CI: 352-658) and 625 d (95%CI: 491-759), respectively. Patients who presented any irAEs achieved a longer PFS than those who did not (median PFS: 533 d vs 179 d, P=0.037, HR=0.57), while patients who presented skin toxicities achieved a longer OS than patients who did not (median OS: 797 d vs 469 d, P=0.006, HR=0.70). CONCLUSIONS In real-world settings, irAEs in lung cancer patients were commonly observed, with pneumonitis as the most common fatal irAEs. In addition, patients who presented any irAEs may tend to achieve a longer PFS.

【Objective】 To observe the effects of mirror neuron system theory(MNST) on hand dexterity and fine motor function in preschool children with developmental coordination disorder(DCD), so as to provide reference for the rehabilitation of children with DCD. 【Methods】 A total of 51 children with DCD treated at Nantong Maternal and Child Health Care Hospital from June 2021 to April 2023 were enrolled in this study, and were randomly assigned to treatment group (n=26) and control group (n=25) except for 5 cases who missed in the follow-up. Both groups received conventional rehabilitation training, while the treatment group received MNST additionally. The hand dexterity and fine motor function of both groups were assessed using the hand dexterity subscale of the Movement Assessment Battery for Children-Second Edition (MABC-2), Peabody Developmental Motor Scale-Fine Motor (PDMS-FM), and Function Independence Measure for Children (WeeFIM) before and after 12 weeks of treatment. 【Results】 Before treatment, there were no significant differences in hand dexterity subscale of MABC-2, PDMS-FM, and WeeFIM scores between the two groups (P>0.05). After treatment, both groups showed improvements in hand dexterity subscale of MABC-2, PDMS-FM, and WeeFIM scores (treatment group: t=35.620, 42.084, 40.072; control group: t=14.000, 12.017, 14.054, P<0.001), with the treatment group showing significantly greater improvements compared to the control group (t=2.611, 3.120, 2.331, P<0.05). 【Conclusion】 MNST combined with conventional rehabilitation training can enhance hand dexterity and fine motor function in children with DCD, thereby improving children′s activities of daily living.
