Objective:To explore the short-term efficacy on 3D printing assisted reconstruction of traumatic digit joint defects using rib and costo-osteochondral autograft.Methods:From August 2022 to July 2023, 7 patients with open digit joint defects had undergone emergency primary debridement and fracture fixation in the Department of Orthopaedics, 988th Hospital of the Joint Logistics Support Force of PLA. Patients with more phalangeal defects that could not be aligned were treated with antibiotic bone cement filling in the emergency surgery. In the second stage surgery, bone cement was removed and transfer of rib cartilage graft was performed to reconstruct the digit joint defect. According to a 1∶1 3D printed hand templates, rib cartilage grafts were crafted to the shape of digit joints, and then spliced together the digit joints and bone defects for fixation. Follow-up X-ray examinations were taken and assessment of the healing status of rib and fractures of phalangeal and metacarpophalangeal bones were carried out according to the Paley fracture healing score. At the outpatient follow-up, assessment of transferred joint movement and evaluation of upper limb function were conducted according to the Evaluation Trial Standards of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association. Visual Analogue Scale (VAS) pain scores were evaluated from the affected digits and donor sites.Results:After reconstructive surgery, all 7 patients had primary healing of the wounds of hand. One patient had fat liquefaction at the donor site, and the rest had primary donor site healing. One patient received further surgery for extensor tendon repair after rib cartilage grafting due to the digital extensor tendon injury. All 7 patients were included in postoperative follow-up for 6-11 months, with an average of 9 months. All patients had excellent fracture healing according to the Paley fracture healing score. At the final follow-up, the extension and flexion of the digit joints were found at 40°-80° (average 56.2°) for proximal interphalangeal joints (4 patients), and 10° in extension and 85° in flexion for metacarpophalangeal joint (1 patient). The range of motion of the thumb interphalangeal joint (2 patients) was 20°-35° (average 27.5°). Hand function was assessed according to Evaluation Trial Standards of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association and it was found that 3 patients were in excellent, 3 in good and 1 in fair.Conclusion:This study focused on the treatment of traumatic digit joint defects by transfer of individually crafted rib cartilages in reconstruction of the defected digit joint. It significantly improves the appearance and function of the defected digit joints, especially suitable for the irregular defects of phalangeal bones.

ObjectiveTo analyze the content and psychological measurement indicators of the commonly used motor function assessment tools for children and adolescents, based on the theory and method of International Classification of Function, Disability and Health-Children and Youth Version (ICF-CY). MethodsBased on the ICF-CY classification framework and coding system, four commonly used functional evaluation tools for children and adolescents were selected, and their motor function measurement methods and psychological measurement indicators were analyzed by applying ICF coding rules and matching principles. ResultsFinally, nine English articles and two Chinese articles were included, from four countries including South Korea, Spain, China and Brazil. They were mainly published in the journals of clinical medicine, neuroscience, public health, rehabilitation science and other fields from 2011 to 2021. The age of the subjects was 0 to 16 years old involving 987 subjects; the health condition included spastic cerebral palsy, neurodevelopmental disorder, etc. Among the eleven articles included, six articles used Gross Motor Function Measure (GMFM-88), two articles used Fine Motor Function Measure Scale (FMFM), two articles used Peabody Developmental Motor Scales Second Edition (PDMS-2), and two articles used Pediatric Evaluation of Disability Inventory-Functional Skills Scale (PEDI-FSS), and three articles used Pediatric Evaluation of Disability Inventory (PEDI). The measurement methods were objective evaluation, subjective evaluation, and subjective observation, etc. The number of measurements was two to six. The measurement indicators of motor function mainly involved two levels. The first was the physical activity level, including gross movement, fine movement and motor control ability. The second was the functional level of activities, mainly including activities of daily living and functional independence. ConclusionBased on ICF-CY, the evaluation of children's motor function and activity and participation was mainly divided into two levels. At the body function level, the main evaluation indicators included b730, b760, b770, etc. At the level of activities and participation, the main evaluation indicators were d410, d440, d445, etc. GMFM-88 focuses on the evaluation of children's body movement and activity functions, such as sitting, standing, lying, walking and running, mainly involving b760, d410, d455, etc. FMFM focused on autonomous movement, motor motivation and motor coordination, and was mainly used to assess the functional status of upper limbs of children with cerebral palsy aged 0 to 3 years, mainly involving b760, d155, d440, etc. PDMS-2 payed more attention to evaluating the overall motor development level and motor function status of children and adolescents, mainly involving b750, b760, d415, etc. PEDI-FSS move partition focused on children's actual motor function performance in activities of daily living, and evaluated the application and practicability of children's motor function in activities of daily living, mainly involving b760, d410, d450, etc. In terms of measurement methods, the measurement of motor function mainly included objective evaluation and subjective evaluation; the measurement of activity function mainly included objective evaluation and subjective observation. These assessment tools have established norms varies with different age groups according to the movement development. Evaluators need accept professional training before using the above assessment tools to improve the reliability, validity and adaptability of the assessment.

OX40 is a costimulatory receptor that is expressed primarily on activated CD4+, CD8+, and regulatory T cells. The ligation of OX40 to its sole ligand OX40L potentiates T cell expansion, differentiation, and activation and also promotes dendritic cells to mature to enhance their cytokine production. Therefore, the use of agonistic anti-OX40 antibodies for cancer immunotherapy has gained great interest. However, most of the agonistic anti-OX40 antibodies in the clinic are OX40L-competitive and show limited efficacy. Here, we discovered that BGB-A445, a non-ligand-competitive agonistic anti-OX40 antibody currently under clinical investigation, induced optimal T cell activation without impairing dendritic cell function. In addition, BGB-A445 dose-dependently and significantly depleted regulatory T cells in vitro and in vivo via antibody-dependent cellular cytotoxicity. In the MC38 syngeneic model established in humanized OX40 knock-in mice, BGB-A445 demonstrated robust and dose-dependent antitumor efficacy, whereas the ligand-competitive anti-OX40 antibody showed antitumor efficacy characterized by a hook effect. Furthermore, BGB-A445 demonstrated a strong combination antitumor effect with an anti-PD-1 antibody. Taken together, our findings show that BGB-A445, which does not block OX40-OX40L interaction in contrast to clinical-stage anti-OX40 antibodies, shows superior immune-stimulating effects and antitumor efficacy and thus warrants further clinical investigation.

Activating humoral and cellular immunity in lymph nodes (LNs) of nanoparticle-based vaccines is critical to controlling tumors. However, how the physical properties of nanovaccine carriers orchestrate antigen capture, lymphatic delivery, antigen presentation and immune response in LNs is largely unclear. Here, we manufactured gold nanoparticles (AuNPs) with the same size but different shapes (cages, rods, and stars), and loaded tumor antigen as nanovaccines to explore their disparate characters on above four areas. Results revealed that star-shaped AuNPs captured and retained more repetitive antigen epitopes. On lymphatic delivery, both rods and star-shaped nanovaccines mainly drain into the LN follicles region while cage-shaped showed stronger paracortex retention. A surprising finding is that the star-shaped nanovaccines elicited potent humoral immunity, which is mediated by CD4+ T helper cell and follicle B cell cooperation significantly preventing tumor growth in the prophylactic study. Interestingly, cage-shaped nanovaccines preferentially presented peptide-MHC I complexes to evoke robust CD8+ T cell immunity and showed the strongest therapeutic efficacy when combined with the PD-1 checkpoint inhibitor in established tumor study. These results highlight the importance of nanoparticle shape on antigen delivery and presentation for immune response in LNs, and our findings support the notion that different design strategies are required for prophylactic and therapeutic vaccines.
