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)
A variety of obstacles have hindered the ultrastructural localization of hyaluronan (HA). These include a lack of adequate fixation techniques to prevent the loss of HA, the lack of highly sensitive and specific probes, and a lack of accessibility due to the masking of HA by HA-binding macromolecules such as proteoglycans and glycoproteins. Despite these(More)
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)

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)
OBJECTIVES To find and compare the levels of acceptance of and barriers to voluntary counselling and testing (VCT) among adults in two different counties of Guizhou province, China, one in which the China CARES project was operating and the other in which it was not. DESIGN A longitudinal design with two-stage cluster sampling was employed. METHODS A(More)
We present the complete sequence of the mitochondrial genome (mitogenome) of the cotton bollworm Helicoverpa armigera. The 15,347-bp mitogenome of H. armigera was arranged in the same order described for all other sequenced lepidopterans, which differs from the most common type found in insects, due to the movement of trnM to a position 5'-upstream of trnI.(More)
Hyaluronan matrices are ubiquitous in normal and pathological biological processes. This remarkable diversity is related to their unique mechanism of synthesis by hyaluronan synthases. These enzymes are normally activated in the plasma membrane and utilize cytosolic substrates directly to form these large polyanionic glycosaminoglycans, which are extruded(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)
