The purpose of this study was to determine the relationships of the anterior cruciate ligament (ACL) femoral insertion site with femoral bony landmarks and develop a new method of location. Sixteen unpaired normal Chinese human cadaveric knees were used. Femoral insertion sites of the ACL were marked with metal wires. Four pairs of bony landmarks were(More)
Addition of an organophosphate source to UMR osteoblastic cultures activates a mineralization program in which BSP localizes to extracellular matrix sites where hydroxyapatite crystals are subsequently nucleated. This study identifies for the first time novel extracellular spherical structures, termed biomineralization foci (BMF), containing bone acidic(More)
OBJECTIVE To study the technical conditions of the extraction and purification of the active composition from Polygonum orientale and Crataegus pinnatifida Bge. in Hongye Xingtong soft capsules with the macroporous resin. METHOD The orientm, isorientm and hyperoside were used as index to screen the five kinds of resins. And the technical conditions of the(More)
Ag/AgBr/TiO2 was prepared by the deposition-precipitation method and was found to be a novel visible light driven photocatalyst. The catalyst showed high efficiency for the degradation of nonbiodegradable azodyes and the killing of Escherichia coli under visible light irradiation (lambda>420 nm). The catalyst activity was maintained effectively after(More)

Mesangial expansion, the principal glomerular lesion in diabetic nephropathy, is preceded by a phenotypic activation and transient proliferation of the glomerular mesangial cells and by a prominent glomerular infiltration of monocytes and macrophages. Because this infiltration seems to play a key role in the subsequent mesangial matrix expansion, we tested(More)
MicroRNAs (miRNAs) are non-coding RNAs that regulate the expression of target mRNAs. Altered expression of specific miRNAs in several tumor types has been reported. However, the expression levels of miR-126 in colorectal cancers are unclear. In this study, we compared the expression of miR-126 between colorectal cancer tissues and non-tumor tissues. The(More)
Previous work has suggested that "calcospherulites" actively participate in the mineralization of developing and healing bone. This study sought to directly test this hypothesis by developing a method to isolate calcospherulites and analyzing their capacity to seed mineralization of fibrillar collagen. The periosteal surface of juvenile rat tibial diaphysis(More)
BACKGROUND Wound excision is the standard treatment for firearm wounds. However, achieving a satisfactory curative effect is difficult because of the traumatic mechanism of high-velocity projectiles. We propose a new therapy by using topical bromelain as a supplement to wound incision for the debridement of firearm wounds. We clarified the debriding effect(More)
OBJECTIVE To examine the feasibility and safety of gastric submucosal tunnel dissection of gastric submucosal tumors (SMTs) by double tunnel and double flex endoscope. METHODS Fifty patients with gastric SMTs detected by gastric endoscopy and endoscopic ultrasonography between January, 2012 and August, 2013 were enrolled in this study. Using carbon(More)
