Methods Mouse models of tibia fracture healing were established, and callus samples were collected 1, 3, 7, 14, 21 and 28 days after fracture. The development of callus and new bone formation were evaluated with roentgenology, Micro-CT and tetracycline double labeling method, and the expression of HIF-1α, vascular endothelial growth factor, Runx2 and ALP in callus were detected with RT-PCR, Western blotting and immunohistochemistry. The relationship between HIF-1α and fracture healing was analysed.

This paper reviewed its pathogenesis, forms, clinical manifestations, differential diagnosis, treatment and prognosis. Here a case of neonatal hypophosphatasia is reported. This baby was female (30 minutes old). Prenatal ultrasound showed disproportionate biparietal diameter and long bones of limbs in the baby. After birth, she presented with obvious craniomalacia, respiratory distress and cyanosis. Serum alkaline phosphatase level was significantly reduced. Both X-ray and autopsy showed extremely insufficient skeletal mineralization. Four days later she died of respiratory failure.

Methods: Thirty adult male Wistar rats were randomly divided into three groups: the operation group, the transplantation of MSCs group and the injection of saline group. Functional outcome measurements were performed based on the modified neurological severity score at day 1, 7, 14, 21 and 28 after MACO. The survival, migration, expression of Nestin, glial fibriliary acidic protein and neuronspecific enolase of 5bromo2deoxyuridinelabeled MSCs were detected by immunohistochemical double staining.
