Objective：To explore the effect of lower limb exoskeleton robot gait training on walking function and gait in children with spastic diplegia cerebral palsy. Method：A total of 21 cerebral palsy children with spastic diplegia who visited the Rehabilitation Department of the Children's Hospital Affiliated to Zhejiang University Medical College from August 2022 to January 2023 were recruited as the treatment group. A matched control group of 21 children was selected based on age, gender, and functional status. Both groups underwent 8 weeks of conventional motor rehabilitation training (including exercise therapy, suspension training, and isokinetic strength training) five times per week. The treatment group additionally received lower limb exoskeleton robot gait training. Before and after 8-week treatment, the 6-minute walk test (6MWT), the Gross Motor Function Measure (GMFM-88) in domains D and E, and gait parameters such as walking of the children such as gait speed, stride frequency, stride length, and support phase duration was evaluated using the IDEEA motion capture system. Result：There was no significant difference (P>0.05) between the two groups of children in terms of 6MWD, GMFM-88 D-zone score, E-zone score, stride speed, stride frequency, stride length, and the proportion of bilateral support phase before treatment. After treatment, both groups showed improvements in 6MWD, GMFM-88 domain D and E score, stride speed, stride frequency, and stride length, while the proportion of bilateral support phase decreased. However, there were no significant differences between the groups in these post-treatment parameters (P>0.05). There were significant differences between groups in 6MWD difference (P<0.01), GMFM-88 domain D score (P<0.01), domain E score (P<0.01), stride speed difference (P<0.05), stride length difference (P<0.05), and bilateral support ratio difference (P<0.01) before and after treatment. The improvement in the treatment group was better than that in the control group. Conclusion：The combination of exoskeleton robot training and routine rehabilitation therapy can effectively improve walking function and gait in children with spastic cerebral palsy.

Objective: To investigate the effect of lower limb exoskeleton robots on balance function in children with spastic diplegia. Method: Twenty children with spastic diplegia who were admitted to the Department of Rehabilitation of the Children's Hospital of Zhejiang University School of Medicine from July 2022 to December 2022 were included in the treatment group. The other 20 children matched with age, gender and functional status were included in the control group. Both groups were given conventional rehabilitation training (exercise therapy, suspension training, isokinetic muscle strength training), and the treatment group were received the 30- min lower limb exoskeleton robot training 5 times a week for 8 weeks. Before and after treatment, the two groups were tested with surface electromyography (sEMG) data, dynamic balance response displacement, static balance score, and Pediatric Balance Scale (PBS) . Result: Before treatment, there was no statistically significant difference (P>0.05) in sEMG values (gluteus maximus, gluteus medius, quadriceps femoris and tibialis anterior muscle), dynamic balance reaction displacement, static balance score, and PBS score between the two groups. There were significant improvements in the scores of these measurements (P<0.05) in both group before and after treatment. Compared with the control group, there were statistically significant differences in sEMG values (gluteus maximus P=0.021；gluteus medius P=0.016；quadriceps femoris P=0.004), dynamic balance reaction displacement (anterior P=0.014；left P=0.003；right P=0.003), static balance score (P=0.005), and PBS score (P=0.004) in the treatment group after treatment. Conclusion： Lower limb exoskeleton robot gait training combined with conventional rehabilitation treatment can effectively improve the balance function of cerebral palsy children with spastic diplegia.

To compare the therapeutic effect of posterolateral and posteromedial approaches internal fixation in the treatment of supination and external rotation type Ⅳ degree ankle fracture. The clinical data of 89 patients with supination and external rotation type IV degree ankle fracture who were treated in our hospital from May 2019 to May 2021 were retrospectively analyzed. They were grouped according to different surgical approaches of plate screw internal fixation, including 41 cases of posteromedial approach (control group), and 48 cases of posterolateral approach (observation group). In the control group, there were 24 males and 17 females, aged from 23 to 65 years, with an average of (39.88±9.36) years. Affected side: 23 cases on the left, and 18 cases on the right. Causes of injury: 26 cases of traffic accidents, and 15 cases of falling from height. In the observation group, there were 27 males and 21 females, aged from 22 to 67 years, with an average of (41.47±9.27) years. Affected side: 28 cases on the left, and 20 cases on the right. Causes of injury: 32 cases of traffic accidents, and 16 cases of falling from height. The fracture healing, operation indexes, ankle function, quality of life and complications were compared between the two groups at 6 months after operation. The excellent and good rate of fracture healing in the observation group was 95.83%, which was significantly higher than 80.49% in the control group (P＜0.05). Compared with the control group, the observation group had less intraoperative blood loss, shorter operation time, fracture healing time and hospitalization time (P＜0.05). There were no differences in ankle function and Short-Form-36 health survey (SF-36) between the two groups before operation (P>0.05). The ankle function and quality of life were improved after operation, while the ankle hindfoot function, Mazur (ankle symptoms and function) score and SF-36 score of the observation group were higher than those of the control group (P＜0.05). The total incidence of complications in the observation group was 4.16%, which was significantly lower than 17.07% in the control group (P＜0.05). The posterolateral approach is more effective than posteromedialapproach in the treatment of supination and external rotation type Ⅳ degree ankle fracture. It can improve the fracture healing rate, ankle function and quality of life, and help to reduce the incidence of postoperative complications. [ABSTRACT FROM AUTHOR]

The apparent dip angle and the distribution parameter are comprehensively analyzed to correct Grasselli’s 3 D morphology parameters system as well as get a new prediction model reflecting the shear behavior of rock joints. The single-valued distribution function Aθ** is used as the weight function to calculate the average apparent dip angle. By defining the relative distribution parameters C*, revealing the control function of distribution parameters on resisting shear. A new peak shear strength prediction model is proposed. Compared with Grasselli’s model, the prediction accuracy of the new model is better verified through 50 sets of published data. The physical and mathematical boundary of distribution parameter C is proposed, and the phenomenon that the value of C from experiments is not less than 1 is explained. The distribution law of apparent dip angle and the composition of initial dilatancy angle are summarized, and the Grasselli’s model is classified into a unified form. The new prediction model has concise parameters, clear physical meaning and mathematical definition, and reveal the shear mechanism of rock joints. [ABSTRACT FROM AUTHOR]

BACKGROUND: Papain inducing knee osteoarthritis has no direct effect on collagen and chondrocyte compared with other chemical inducers. OBJECTIVE: To evaluate the effectiveness of early osteoarthritis model of knee joint in rats by the surface morphology, radiology and histopathology of cartilage. METHODS: Twenty adult male Wistar rats were provided by Qinglongshan Animal Breeding Farm of Jiangning District, Nanjing, and the study was approved by the Ethics Committee of Liuhe Hospital Affiliated to Yangzhou University Medical College. The rats were randomly divided into control and experimental groups. At 1, 4 and 7 days, 4% normal saline and 4% papain were injected into the rat right knee joint cavity in the control and experimental groups, respectively. Rats were killed at 10 days. The articular cartilage morphology,X-ray and three-dimensional CT images were observed before the execution. Histopathological examination was performed immediately after the execution, and the results were verified by Mankins and OARSI scores. RESULTS AND CONCLUSION: (1) Compared with the control group, in the experimental group, the limp was obvious, the knee joint swelling on the injection side was obvious, and the hind limbs were unwilling to land. Radiological examination showed that the joint space narrowed obviously, and the value of three-dimensional CT joint space was significantly decreased [(0.680 0±0.016 3)vs.(0.558 0±0.033 9) mm, P < 0.05]. (2) Microscopic examination showed early stage inflammation characteristics at the right knee joint in the experimental group. There were significant differences in the Mankins and OARSI scores (P < 0.05). (3) In summary, early knee osteoarthritis induced by intra-articular injection of papain into the right knee joint of rats can be used in relevant clinical studies, because it provides measurable changes in joint motion, tactile abnormal pain, progressive radiodegeneration and micro-inflammation of articular cartilage, representing the evaluation of osteoarthritis, and providing a basis for studying the pathogenesis of early knee osteoarthritis.

Taking the gravity anomalies of regular shape bodies as conversion model, this paper summarizes the features three potential field data processing algorithms, and operates model calculation using gradient algorithm, analytical continuation algorithm, boundary extraction algorithm, respectively, based on Matlab. The gradient algorithm is able to recognize and separate the anomalies coming from different sources. The analytical continuation algorithm contributes to suppress and highlight the information of deep or shallow sources. The boundary extraction algorithm is skilled at reflecting the borders of sources in the form of gradient zone and phase step. Finally, the methods are applied to the processing and interpretation of the actual Bouger gravity anomalies data in Tarim Basin from the perspective of data mining. It is concluded that the major fracture systems that orientate NE, NW and NEE are parallel to the borders of the basin. [ABSTRACT FROM AUTHOR]
