BACKGROUND:The favorable structure and biological characteristics of al ogeneic temporomandibular joint become an effective solution for condylar defect, but immunologic rejection and slow ossification are the main problem for the presence of bone al ograft. OBJECTIVE:To meet the requirements of rebuilding mandible defect by lyophilizing canine mandible. METHODS:The periosteum, soft tissue, and cartilage of 12 canine mandibles were removed. 1 mm diameter hole was dril ed with 1 to 2 cm intervals in their cortical bones with a fissure bur. After washing, they were placed into a-4 ℃ refrigerator for 12 hours, and then stored at-80℃gradual y for 1 week. The mandibles were put in a drier. When the moisture content of osseous tissue decreased to 5%, the bones were packed in aseptic environment, radio pasteurized, and stored in vacuum container at atmosphere temperature. A biomechanical test was conducted after the lyophilization. RESULTS AND CONCLUSION:The maximum shifts of lyophilized mandibles in compression and bending tests were slight according to the steep load-shift curve. The plastic zone was insignificant and fractures appeared immediately when the pressure exceeded the plastic zone. The maximum load, maximum shift, and rigidity in the compression test were (5 163.10±730.16) N, (0.78±0.19) mm and (11 069.17±1 758.12) N/mm, respectively. The data in bending test were (486.67±134.12) N, (0.67±0.15) mm and (1 151.67±256.46) N/mm, respectively. It is concluded that the dehydrated and lyophilized canine mandibles have good shape and support ability and can meet the mechanical requirements in repairing and reconstructing mandibular defect.

Objective:To investigate the frequency and severity of systemic adverse reactions in children with allergic rhinitis (AR) undergoing subcutaneous immunotherapy (SCIT).Methods:The clinical data of 321 children with allergic rhinitis receiving SCIT at Department of Otorhinolaryngology, Changzhou Third People′s Hospital from January 2016 to January 2020 were retrospectively analyzed. There were 180 boys and 141 girls aged 5 to 14 years. Patients were injected subcutaneously with standardized dust mites allergen extract. The onset time, symptoms and signs and treatment of adverse reactions were documented. The relationship of adverse reactions with gender, age, treatment course and dosage of allergen injection were analyzed.Results:Patients received total 13 053 injections, and 115 adverse reactions (0.88%) occurred in 56 cases (17.45%). The incidence of adverse reactions in children aged 5-9 years was higher than in those aged 10-14 years, for both the number of cases and injections (χ2=4.41, P=0.04; χ2=9.13, P<0.01), but no significant differences were observed in gender of patients. The incidence of adverse reactions in the age group 2-3 years was lower than that in age groups<1 year and 1-<2 years in both of cases and injections (χ2=22.86, P<0.01; χ2=6.43, P=0.01; χ2=12.14, P<0.01; χ2=13.74, P<0.01). The incidence of adverse reactions in the high-dosage phase (100 000 SQ-U) was higher than that in the low-dosage phase (<100 000 SQ-U) (χ2=4.35, P=0.04). Conclusions:The study shows that the incidence of adverse reactions in children with allergic rhinitis receiving subcutaneous immunotherapy is less than 1% in the number of injections and most of them are grade Ⅰ adverse reactions. The study also shows that younger age, the early course of treatment and the high dosage of allergens are risk factors for adverse reactions.

BACKGROUND:Al ogeneic bone has anatomical appearance and biological features similar to autogenous bone, which is an excel ent biological scaffold material. Mesenchymal stem cel s originating from autogenous bone marrow have mutli-lineage differentiation potential, can differentiate into osteoblasts and chondrocyte, and thus can accelerate the formation of bone tissue and cartilage tissue. OBJECTIVE:To establish the osteogenic ability of al ogeneic bone with autogenous bone marrow mesenchymal stem cel s for repairing major mandibular defects. METHODS:The left mandibular teeth of 24 beagles were extracted, and at 2 months after wound healing, mandibular defects were made artificial y. The beagles were divided into two groups:control group treated with lyophilized al ogeneic bone, and experimental group with autogenous bone marrow mesenchymal stem cel s and lyophilized al ogeneic bone. Densitometry with CT and Micro-CT was conducted 4, 12, and 24 weeks after surgery. RESULTS AND CONCLUSION:Compared with the control group, the bone density of the mandible was significantly higher in the experimental group at 12 weeks after transplantation (P<0.05). Over time, the bone densities in the two groups were both increased, but the bone density in the experimental group was always higher than that in the control group. Bone structure parameters were progressively increased or decreased in the two groups, especial y in the experimental group. At 24 weeks after surgery, the degree of trabecular separation in regions of interest was higher in the experimental group than the control group (P<0.05), but the bone volume fraction, number of trabecular bone, and bone trabecular thickness were significantly lower in the experimental group than the control group (P<0.05). These findings indicate that bone marrow mesenchymal stem cel s are capable of accelerating the reconstruction of al ogeneic bones.
