This study was aimed to investigate the protective effect of catalpol against high glucose induced injury on vascular endothelial cells (ECV-304). ECV-304 cells were culturedin vitro. MTT method was applied to detect cell viability. NO and LDH level were measured by spectrophotometer method. The effect of catalpol against high glucose induced injury on ECV-304 was observed. The results showed that there were no obvious changes in cell viabilities of ECV-304 cultured in normal concentration of glucose medium among groups with different concentrations of catalpol. Compared with the control group, cell viability was significantly decreased (P< 0.01), the NO secretion was significantly reduced (P< 0.01), the LDH level was increased obviously (P< 0.01) in the high glucose (30 mmol·L-1 glucose) injury model group. The high osmotic (24.5 mmol·L-1 mannitol) group was set up as a positive control. Comparison between the low dose (1 ng·μL-1 catalpol + 30 mmol·L-1 glucose), middle dose (10 ng·μL-1 catalpol+ 30 mmol·L-1 glucose), and high glucose (30 mmol·L-1 glucose) injury model group showed no changes on cell viability and NO (P> 0.05); while the LDH level was reduced (P< 0.01). Comparison between the high dose catalpol (100 ng·μL-1 catalpol + 30 mmol·L-1 glucose) group and the high glucose model group showed that the cell viability was obviously increased (P< 0.01); NO secretion was increased (P< 0.05); and the LDH level was obviously reduced (P< 0.01). It was concluded that catalpol had protective effect against high glucose induced ECV-304 injury through the regulation of NO and LDH level. The effect of high dose was obvious.

Functional analysis concisely summarizes and concentrates on the therapeutic characteristics and features of Chinese herbal medicine. Standardization of the terms for Chinese herbal functions not only plays a key role in modern research and development of Chinese herbal medicine, but also has far-reaching clinical applications. In this paper, a new method for standardizing the terms for Chinese herbal function was proposed. Firstly, functional targets were collected. Secondly, the pathological conditions and the mode of action of every functional target were determined by analyzing the references. Thirdly, the relationships between the pathological condition and the mode of action were determined based on Chinese medicine theory and data. This three-step approach allows for standardization of the terms for Chinese herbal functions. Promoting the standardization of Chinese medicine terms will benefit the overall clinical application of Chinese herbal medicine.

To reduce the mismatching and non-matching in the protein two-dimension electrophoresis (2-DE) images, we proposed an auto-matching algorithm based on gray hierarchical and geometric blocking in this study. Firstly, protein spots in the gel images were divided into groups by gray level and geometric position, and then a method based on shape context and normalized correlation was used for coarse matching in protein spots. Secondly, matched pairs in coarse matching were set as feature points, and the precise matching in the rest of not matched protein spots was accomplished by the method of geometric correlation and similarity criterion. Finally, local affine transformation was used in the verification of matching results to remove non-matching and mis-matching points. The algorithm was applied to different 2-DE gel images. The results showed that the new matching algorithm could reduce the non-matching and mis-matching spots, and increase the matching accuracy.

Purpose:To investigate the relationship between cell apoptosis and dephosphorylated RB protein in human breast cancer. Methods:In our work,human breast cell lines (MCF-7/S,the chemosensitive cell line and MCF-7/ADR,the chemoresistent cell line)were evaluated. Chemosensitivity of two cell lines was evaluated by the MTT colorimetric assay;the expressive levels of dephosphorylated RB protein were detected with immunocytochemistry. Apoptosis rates were determined by flow cytometry(FCM). Results:ADR inhibited proliferation of chemosensitive cell line MCF-7/S ,the 50% inhibition concentration (IC 50 ) was 0.128 ?g/ml;And IC 50 of MCF-7/ADR was 10.89 ?g/ml. The chemotherapeutic sensitivity of MCF-7/S was more than that of MCF-7/ADR by 86 times . Before treatment with ADR,phosphorylated RB protein was positive in two cell lines,but dephosphorylated RB protein was negative;After treatment of different concentration ADR,when the concentration of ADR was increased,expression of dephosphorylated RB protein elevated accordingly in MCF-7/S,but no significant change in MCF-7/ADR. Apoptosis and cell cycle was detected by FCM assays shows ADR induced apoptosis of MCF-7/S more than MCF-7/ADR(P0.05).
