Objective:To explore the effects of sandplay combined with sensory integration therapy on cognitive function in children with attention deficit hyperactivity disorder (ADHD).Methods:60 children with ADHD diagnosed in Baoji Maternal and Child Health Hospital from June 2018 to June 2019 were randomly divided into study group and control group.The children in the control group were treated by sandplay, while the patients in the study group were treated by sandplay combined with sensory integration.Results:There was no significant difference in Parent Symptom Questionnaire (PSQ) score, Combined Raven Test (CRT) results and attention test results between the two groups before treatment ( P>0.05), and there was no significant difference in PSQ score of control group after treatment ( P>0.05); The behavioral problems (0.92±0.23), anxiety (0.51±0.26), impulse/hyperactivity (1.06±0.31) and hyperactivity index (0.88±0.14) in the study group were significantly lower than those in the control group [behavioral problems (1.12±0.21), anxiety (0.79±0.45), impulse/hyperactivity (1.42±0.34) and hyperactivity index (1.16±0.17) ( P<0.05)]. There was no significant difference in the scores of mental disorders and learning problems between the two groups [(0.42±0.20), (1.28±0.44) vs (0.52±0.28), (1.37±0.48)] ( P>0.05). The results of CRT in the study group were (6.6±0.3, 7.3±0.2, 9.1±0.1, 5.5±0.2, 2.7±0.1, 117.3±4.4), which were higher than those in the control group (6.2± 0.1, 6.7±0.1, 8.7±0.1, 5.0±0.1, 2.2±0.1, 110.0±3.8) ( P<0.05). The slip time (52.4±0.1), error number (55.9±0.2) and missed report number (60.2 ±0.1) of the study group were significantly lower than those of the control group [slip time (56.1±0.2), error number (60.3±0.1) and missed report number (70.8±0.3)] ( P<0.05). Conclusions:Combination of sandplay and sensory integration can significantly improve the cognitive and behavioral abilities of children with attention deficit hyperactivity disorder, and improve the balance function of children, which is conducive to clinical application.

BACKGROUND AND OBJECTIVES: The purpose of this study was to compare the nasality and acoustic variables of control subjects and those of patients with deviated nasal septum (DNS), preoperatively and postoperatively. SUBJECTS AND METHOD: Twenty patients who underwent septoturbinoplasty (DNS group) and ten control subjects (control group) who did not complain of nasal obstruction or did not show any anatomic or pathologic abnormality were selected. Performed for these subjects were acoustic rhinometry, rhinomanometry, nasality test and long-term average spectrum analysis of nasal sound sentence. Data were collected and analyzed prior to and 4 weeks after the surgery. RESULTS: In DNS group, the volume of nasal cavity was significantly increased and the nasal resistance was decreased significantly after operation. There were no statistically significant differences in the nasality of all sentences in the DNS group compared to those in the preoperative and the postoperative group. However, alternations of several acoustic variables in the final consonant were detected. CONCLUSION: Alternation of nasality and acoustic variables was observed after septoturbinoplasty, however, the changes of nasal resistance have been shown to contribute to the results.

Objective:To explore our self-designed classification system of irreducible intertrochanteric fractures based on reduction stage and bone block position and to evaluate the reduction techniques guided by the classification system.Methods:A retrospective study was conducted to analyze the data of 115 patients with irreducible intertrochanteric fracture who had been admitted to Department of Orthopedics, Beijing Hospital from September 2014 to November 2022. There were 24 males and 91 females with a mean age of (80.9±11.0) years. The reduction for the fractures was divided into a diaphysis reduction stage (Phase Ⅰ) and a cortical reduction stage (Phase Ⅱ). Based on the relative positions of the intraoperative bone blocks, Phase Ⅰ was divided into an anterior and posterior interlocking type (Phase Ⅰa) and a distal bone block sinking displacement type (Phase Ⅰb) while Phase Ⅱ into a proximal lifting type (Phase Ⅱa), a posterior angulation type (Phase Ⅱb), a positive support type (Phase Ⅱc), and a negative support type (Phase Ⅱd). Depending on the difficulties encountered in different reduction stages, corresponding close reduction strategies (such as top rod support, percutaneous prying, and Joystick technique) were adopted to restore the proximal femoral neck shaft angle, anteversion angle, anterior medial cortex, and length of the affected limb before fixation with intramedullary nails. Recorded were the patient's surgical time, intraoperative bleeding, quality of postoperative reduction, fracture union time, and complications.Results:The surgical time for this group of patients was 70.0(60.0, 92.0) minutes, and the intraoperative blood loss 200.0 (170.0, 200.0) mL. According to the standards by Baumgaertner et al., the quality of postoperative reduction was evaluated as excellent in 103 cases and as good in 12 cases, with an excellent and good rate of 100.0% (115/115). Of the 115 patients, 86 were followed up for more than 6 months to reveal fracture union in all after a duration of 6.0 (4.0, 8.0) months. One patient died of an acute cardiovascular event in the hospital 5 days after surgery. Two patients lost their mobility within 3 months after surgery due to acute cerebral infarction. There was no internal fixation failure requiring secondary surgery or no incision infection.Conclusion:Guided by our self-designed classification system of irreducible intertrochanteric fractures based on the intraoperative reduction stage and the relative position of bone block, real time intraoperative fluoroscopy images can be used to effectively clarify the difficulty of fracture reduction in stages so that corresponding reduction strategies can be adopted, leading to fine clinical efficacy.
