ObjectiveTo investigate the effect of different visual inputs and task conditions on balance function and lower limb biomechanical characteristics in children with spastic hemiplegia. MethodsFrom March to July, 2025, 30 children aged six to nine years old with spastic hemiplegia (hemiplegia group) and 30 healthy children (control group) were selected. A 2×2×2 mixed experimental design was employed, involving groups (hemiplegia vs. healthy), tasks (single-task vs. dual-task), and vision (eyes open vs. eyes closed). One week before test, they were evaluated with Fugl-Meyer Assessment-Lower Extremities (FMA-LE), Wee Function Independent Measurement (WeeFIM) and Wechsler Intelligence Scale for Children, Fourth Edition (WISC-Ⅳ). A 3D gait analysis system and a plantar pressure testing system were used to collect spatio-temporal parameters of walking speed, stride length, cadence and step width, kinematic parameters of hip/knee/ankle joint angles, kinetic parameters of forefoot loading ratio, center of pressure (CoP) displacement, while dual-task cost (DTC) was caculated. ResultsSpatio-temporal parameters showed that under dual-task and eyes-closed conditions, walking speed and stride length decreased while step width increased in the hemiplegia group. Significant interaction effects among group, task, and vision were observed for speed, stride length, and step width (F > 4.886, P < 0.05). Kinematic parameters indicated that during dual-tasks, the hemiplegia group exhibited increased hip flexion and decreased ankle dorsiflexion; under eyes-closed conditions, knee flexion increased. The interaction of the three factors significantly affected all joint angles (F > 4.876, P < 0.05). Kinetic parameters showed that under dual-task and eyes-closed conditions, the forefoot loading ratio and anteroposterior CoP displacement decreased, while mediolateral CoP displacement increased. The interaction of the three factors significantly affected CoP displacement (F > 4.355, P < 0.05). All the DTC was significantly higher in the hemiplegia group than in the control group, except DTC of the cadence (|t| > 14.393, P < 0.001). Correlation analysis revealed that the score of FMA-LE was strongly negatively correlated with DTC (|r| > 0.731, P < 0.01). The Functional Independence Measure for Children and Working Memory Index showed moderate negative correlations with the DTC of walking speed and cadence (|r| > 0.462, P < 0.05). ConclusionThe gait and balance of children with spastic hemiplegia are concurrently influenced by dual-tasking and visual input. The superposition of visual deprivation and dual-tasks significantly exacerbates gait abnormalities. Furthermore, is strongly correlated with motor function and working memory.

Objective To study the efficacy of speech training combined with Montessori education on speech problems in children after velopharyngeal insufficiency surgery.Methods A retrospective analysis of 63 cases of children who underwent velopharyngeal repair at Children's Hospital of Soochow University between January 2019 and December 2021 was conducted.Subjects were divided into three groups.A total of 21 patients who received family rehabilitation training after the operation were divided into control group A,42 patients who received regular hospital rehabilitation training after the operation were divided into group B and group C,of which 21 patients in group B received routine speech training,and 21 patients in group C received Montessori education and routine speech training.Nasal resonance status,assessment of dysarthric intelligibility,and cranially positioned lateral radi-ographs when pronouncing/i/sounds were evaluated individually before treatment and 6 months after treatment.The improvement of velopharyngeal function,nasal resonance status,and dysarthric articulation were evaluated.Results After the six-month intervention,the dysarthric speech intelligibility were significantly improved in three groups with improvement of 35.45％in group A,43.66％in group B,and 49.33％in group C,respectively(P＜0.05).The improvement rate of nasality reached 100％in the B and C group with nasality elimination rate of 70％in group B and 95.24％nasality elimination in group C,and the efficacy of the two groups was statistically signifi-cant(P＜0.05).During phonation of the/i/tone,velopharyngeal insufficiency was observed in seven patients in group B and in only one patient in group C,and the efficacy was statistically significant in both groups(P＜0.05).Conclusion Postoperative targeted speech training is necessary in patients with velopharyngeal insufficiency,and speech training combined with Montessori education can significantly improve the function of velopharyngeal clo-sure,thus achieving a good state of nasal resonance and correct articulation as early as possible.

Changes in structure of oral solid dosage forms (OSDF) elementally determine the drug release and its therapeutic effects. In this research, synchrotron radiation X-ray micro-computed tomography was utilized to visualize the 3D structure of enteric coated pellets recovered from the gastrointestinal tract of rats. The structures of pellets in solid state and in vitro compendium media were measured. Pellets in vivo underwent morphological and structural changes which differed significantly from those in vitro compendium media. Thus, optimizations of the dissolution media were performed to mimic the appropriate in vivo conditions by introducing pepsin and glass microspheres in media. The sphericity, pellet volume, pore volume and porosity of the in vivo esomeprazole magnesium pellets in stomach for 2 h were recorded 0.47, 1.55 × 10⁸ μm³, 0.44 × 10⁸ μm³ and 27.6%, respectively. After adding pepsin and glass microspheres, the above parameters in vitro reached to 0.44, 1.64 × 10⁸ μm³, 0.38 × 10⁸ μm³ and 23.0%, respectively. Omeprazole magnesium pellets behaved similarly. The structural features of pellets between in vitro media and in vivo condition were bridged successfully in terms of 3D structures to ensure better design, characterization and quality control of advanced OSDF.

Objective:To investigate the dynamic changes of mitochondrial fission and fusion in the heart of cardiac arrest (CA) rats after return of spontaneous circulation (ROSC), and to explore the role of mitochondrial fission and fusion in the myocardial injury after ROSC.Methods:Healthy male SD rats were randomly random number assigned into the post-resuscitation (PR) 4 h ( n=12), PR 24 h ( n=12), PR 72 h ( n=12), and sham groups ( n=6). The rat CA model was induced by asphyxia, and cardiopulmonary resuscitation (CPR) was performed 6 min after CA. The protein expressions of mitochondrial Drp1, Fis1, Mfn1, and Opa1 were determined by Western blot in each group at 4, 24 and 72 h after ROSC. The mRNA expressions of Drp1, Fis1, Mfn1, and Opa1 were determined by RT-PCR. Myocardial ATP content and mitochondrial respiratory function were measured. The histopathologic changes of myocardial tissue were observed under light microscope. One-way analysis of variance (ANOVA) was use to compare quantitative data, and LSD- t test was used for comparison between groups. Results:Compared with the sham group, the protein and mRNA expressions of Drp1 and Fis1 were increased (all P<0.05) and the protein and mRNA expressions of Mfn1 and Opa1 were decreased (all P<0.05) in the PR 4 h and PR 24 h groups. However, there were no statistical differences in the protein and mRNA expressions of Drp1, Fis1, Mfn1, and Opa1 in the PR 72 h group compared with the sham group (all P>0.05). Compared with the sham group, the levels of ATP content [(4.53±0.76) nmol/g protein vs. (8.57±0.44) nmol/g protein and (5.58±0.58) nmol/g protein vs. (8.57±0.44) nmol/g protein] and mitochondrial respiratory control rate [(2.47±0.38) vs. (3.45±0.32) and (2.97±0.24) vs. (3.45±0.32)] were obviously decreased in the PR 4 h and PR 24 h groups (all P<0.05). There were no statistically significant differences in the ATP content [(7.73±0.95) nmol/g protein vs. (8.57±0.44) nmol/g protein] and mitochondrial respiratory control ratio [(3.39±0.34) vs. (3.45±0.32)] between the PR 72 h group and the sham group (all P>0.05). The pathological damage of myocardial tissue was obvious in the PR 4 h group, and was improved significantly in the PR 72 h group. Conclusions:The imbalance of mitochondrial fission and fusion is probably involved in the pathological process of myocardial injury after ROSC, which may be related to mitochondrial dysfunction.

Objective:To explore the effect of the implantation of absorbable stents on the prognosis of patients with inferior knee artery balloon dilatation.Methods:From March 2018 to January 2021, twenty-five patients with drug absorbable stent implantation after inferior knee artery balloon dilatation (stent group) and 25 patients without absorbable stent implantation after inferior knee artery balloon dilatation (control group) were included in Qingdao Haici Medical Group Affiliated to Qingdao University. The improvement of symptoms, ankle brachial index, Rutherford classification and claudication distance before and after operation were compared. The symptoms, ankle brachial index, Rutherford grade, claudication distance and patency rate of the two groups were compared 6 months after operation. The preoperative and postoperative data were analyzed by independent sample t-test, and the patency rate was analyzed by χ 2 test. Results:The ankle brachial index in the stent group and the control group on the first day after operation was significantly higher than that before operation (0.18±0.11 vs. 0.85±0.15, t=18.5, P<0.05, 0.22±0.15 vs. 0.87±0.10, t=20.8, P<0.05), and the Rutherford classification decreased significantly (4.66±0.21 vs. 2.1±0.11, t=9.2, P<0.05, 4.58±0.33 vs. 2.3±0.22, t=12.9, P<0.05), the limp distance increased significantly ((27±8) m vs. (300±43) m, t=20.8, P<0.05, (42±14) m vs. (320±18) m, t=32.6, P<0.05). There was no significant difference in preoperative ankle brachial index, postoperative ankle brachial index, Rutherford grade and claudication distance between the two groups ( P>0.05). Six months after operation, the ankle brachial index (0.72±0.03 and 0.54±0.12; t=10.2, P<0.05), Rutherford classification ((1.72±0.17) and (3.23±0.22); t=12.8, P<0.05) and claudication distance ((580.00±137.00) m and (267.00±54.00) m; t=8.2, P<0.05) in the stent group and the control group were significantly better than those in the control group. The patency rate of stent group at 6 months was 68% (17/25), which was better than that of ordinary balloon dilatation group by 56% (14/25). Conclusion:Implantation of drug absorbable stents can significantly improve the prognosis of patients undergoing arterial balloon dilatation.

Objective To explore the clinical efficacy of artificial liver technique - double plasma molecular adsorption(DPMAS) combined with continuous renal replacement therapy(CRRT) in the treatment of multiple organ dysfunction syndrome(MODS) patients with liver failure. Methods From April 2014 to October 2016, in the Qinghai Provincial People's Hospital emergency ICU hospitalized MODS combined with liver failure patients were enrolled in this study. On the basis of comprehensive medical treatment, these patients were randomly(random number) divided into CRRT control group(23 cases) and DPMAS + CRRT treatment group(22 cases). Blood biochemical, coagulation index, inflammatory factor and severity score of two groups were comparied before and 72 h after treatment. Results The levels of alanine aminotransferase(ALT), aspartate aminotransferase(AST), blood amine(NH3), creatinine(CREA), interleukin-6(IL-6), tumor necrosis factor-α(TNF-α), heart rate(HR),APACHE Ⅱ score and SOFA score in CRRT control group were statistically different before and after treatment (P<0.01). However, there was no significant difference in the levels of total bilirubin(TBIL), direct bilirubin(DBIL), bile acid(TBA), prothrombin activity(PTA) and international standardized ratio(INR) (P> 0.05); In the DPMAS + CRRT treatment group, the levels of ALT, AST, NH3, CREA, IL-6, TNF-α, HR, APACHEⅡand SOFA scores were significantly different before and after treatment (P<0.01), as well as the levels of DBIL, TBA, PTA, INR(P<0.01). There was significant differences in ALT, AST, TBIL, DBIL, TBA PTA, INR, IL-6, TNF-α, APACHE Ⅱ and SOFA scores between the two groups (P<0.05), while the levels of CREA, NH3, MAP, HR of these two groups had no significant difference (P>0.05). Conclusions Because of the combination of double plasma adsorption, besides the advantages of CRRT, DPMAS+CRRT can remove bilirubin and bile acid which can not be removed by CRRT, also improve coagulation function. The clearance efficiency of inflammatory factors is also higher, and the severity score is reduced more significantly.
