Methods： Cancellated bone were made as 30 mm × 3 mm × 3 mm bone blocks from inferior extremity of pig femur along bone trabecula. The deproteinized bone was prepared with an improved method. Their morphological features, components, cell compatibility, mechanical and immunological properties were investigated respectively. Results： Deproteinized bone maintained natural re-ticular pore system. The main organic material is collagen I and inorganic composition is hydroxyapatite. It has good mechanical properties, cell adhesion rate and histocompatibility. Conlusion： This deproteinized bone can be applicable as scaffold for reparation of big segmental defect in long bone.展开更多

Methods: 120 cases of patients with corneal epithelial defect caused by mechanical injury were selected and randomly divided into observation group (60 eyes, deproteinized calfblood extract eye gel in use) and control group (0.3% ofloxacin eye drops in use). Both two groups of patients were given eye gel or eye drops 4 times per day. Moreover, the two groups of eye symptoms and corneal epithelial healing were observed on the 3rd day and the 7th day after drug usage respectively. Results: The effective rates of 20% deproteinized calfblood extract eye gel on the treatment of mechanical corneal epithelial defect on the 3rd day and the 7th day were 78.33% and 93.33% respectively. Meanwhile, the effective rates of 0.3% ofloxacin eye drops were 55.00% and 71.67%. The difference in the comparison of the effective rate between two groups was of statistical significance (p < .05). Conclusions: 20% deproteinized calfblood extract eye gel can significantly promote the healing of corneal epithelium in a short time, and it is worthy to be widely applied clinically.展开更多

According to the results of the airtight hypoxia experiment, mice in the model+DECB group had a signifi? cantly prolonged time of hypoxia tolerance compared with the model group. The biochemical test indicated that DECB could significantly increase the level of sugar, ATP and proteins and reduce the amount of lactic acid in mice. It also revealed that Hmgcs2, Cptla, Angptl4, Cyp8b], and Ehhadh genes were involved in mice energy metabolism, and were closely associated witli metabolic signaling pathway. These results suggest that DECB might be a potential drug to treat metabolic diseases. Among the genes with differential expression under hypoxia, Angptl4, Cyp8bl, and Ehhadh were critical factors for sugar metabolism. Hmgcs2 provided energy directly, and Cptla regulated cellular inflammatory responses, promoting energy metabolism.展开更多
