Objective To investigate the effects of vitamin D deficiency in early life on growth and development and subclinical bone health in neonatal rats. Methods Twenty-seven healthy adult SD rats (9 males and 18 females) were selected. All female SD rats were randomly divided into the control group, vitamin D deficiency group (VDD group) and vitamin D supplement group (VDS group), with 6 rats in each group. Rats in the VDD and VDS groups were fed with vitamin D deficiency diet, while rats in the control group and all male mice were fed with standard diet. They were fed for 4 weeks and mated at a male-to-female ratio of 2∶1. After successful mating, rats in the control group and VDS group were fed with standard diet and illuminated by incandescent light, and rats in the VDD group continued to be fed with vitamin Ddeficient diet and illuminated by white LED light. After delivery, rats in the VDD group continued to be fed with vitamin D deficient diets and illuminated by bright white LED lighting, while rats in the control and VDS groups continued to be fed with standard diets and illuminated by incandescent lighting. The young mice were fed 21 days after lactating and were fed according to the above conditions until the 7th weekend of birth. At the 1st,2nd,3rd and 4th weekends after birth, the body mass and tail length were measured. At the 7th weekend after birth, blood was taken from the heart after anesthesia and serum was retained by centrifugation. Serum Ca2+ was detected by azo-arsenic Ⅲ method, serum parathyroid hormone (PTH) was detected by two-site enzyme immunoassay, and serum 25 hydroxyvitamin D［25-(OH) D］ was detected by ELISA. The whole body bone mineral content and bone mineral density were measured by dual-energy X-ray bone densitometer. Serum phosphorus was detected by enzyme assay, serum insulin-like growth factor 1(IGF-1) was detected by ELISA, and serum type I procollagen N-terminal lengthening peptide (P1NP) and alkaline phosphatase (ALP) were detected by chemiluminescence immunoassay. Results The body weight, body length and tail length of rats in the control group and VDS group were higher than those in the VDD group at the 1st to 4th weekends after birth (all P<0. 05), and the body weight, body length and tail length of rats in the VDS group were higher than those in the VDD group at the 1st to 4th weekends after birth (all P<0. 05). At the end of the 7th week, serum Ca2+,25-(OH) D, ALP, phosphorus, IGF-1 levels, bone mineral content and density of rats in the control group and VDS group were higher than those in the VDD group, while serum PTH and P1NP levels were lower than those in the VDD group (all P<0. 05). Serum ALP, phosphorus, IGF-1, bone mineral content and density of the VDS group were higher than those of the control group, and serum P1NP level was lower than that of the control group (all P<0. 05). Conclusion Vitamin D deficiency in early life can affect the growth and development of offspring rats and lead to subclinical bone health, while timely supplementation of vitamin D can promote the growth and development, and reverse the subclinical bone health.

Porous material structures have been widely used in civil engineering, mechanical engineering, aerospace engineering and other fields due to their high specific strength and specific stiffness. The stochastic response analysis of porous material structures under random excitations deserves more attention. The multiscale governing differential equations for porous material structures were derived based on the multiscale asymptotic-homogenization method (AHM), and the macroscale and microscale explicit time-domain expressions of structural responses were further established. On this basis, the statistical moments of dynamic responses of porous material structures under non-stationary random excitations were achieved with the explicit time-domain method (ETDM). The proposed method combines the advantages of the AHM for high-efficiency explicit formulation of macroscale and microscale dynamic responses of porous material structures and the benefits of the ETDM for fast analysis of non-stationary random vibration problems. A numerical example shows the computation accuracy and efficiency of the presented approach for non-stationary random vibration analysis of porous material structures. [ABSTRACT FROM AUTHOR]

BACKGROUND: In recent years, distraction osteogenesis has become an important alternative option to the reconstruction of mandibular segmental bone defects. OBJECTIVE: To explore the clinical feasibility and efficiency of transport distraction osteogenesis for reconstruction of segmental mandibular bone defect and later dental implantation. METHODS: Six patients with ameloblastoma or keratocystic odontogenic tumor were included in this study. Computed tomography and panoramic film were performed for preoperative evaluation and surgical planning. Transport distraction osteogenesis was used to reconstruct the defect after tumor resection. The fixation period after distraction varied from 16 to 25 weeks, depending on the degree of ossification in the distraction space after operation. The second operation was performed to remove the traction device and restore the gap between the delivery disc and the residual bone defect with bone graft and rigid internal fixation. Finally, the occlusal relationship was restored by dental implantation on the new bone in the distraction space. RESULTS AND CONCLUSION: All patients successfully completed the whole treatment period without traction failure or tumor recurrence. The stretch length ranged from 45 to 57 mm. Satisfactory new bone formation and high calcification in the distraction space were confirmed by imaging examination and intraoperative observation. Of the six patients, one developed infection, and the symptoms were controlled by surgical dressing change; two had salivary leakage, and were cured by pressure bandaging and atropine. All patients eventually achieved satisfactory facial appearance and occlusal function. The findings of this study indicate that transport distraction osteogenesis can be used to reconstruct segmental mandibular bone defect and further used in clinical dental implant treatment, and moreover, the therapeutic effect is satisfactory.
