Objective To investigate the correlation between hepatitis B virus(HBV)markers and AFU,ALT,GGT.Methods 570 eases of HBV-infected people were divided into 4 groups according to the different performance modes.150 healthy people were considered as control group.rate method was used to detect AFU,ALT and GGT.Estimate the differences between the groups were compared.Results The comparison between the AFU,ALT,GGT in different performance mode of HBV and the control group showed:the differences of group 1,group 2 and group 3 were statistically significant(P＜0.01),the difference of group 4 was not significant(P＞0.01).The correlation between AFU,ALT,GGT of different performance mode showed:the changes of AFU and ALT,GGT in group 1,group 2 and group 3 were positively change-related.But the changes of AFU,ALT and GGT were not clearly related.The distribution of the rise of serum enzyme activity in different performance mode showed:the AFU,ALT and GGT rised in different proportion in group 1,group 2 and group 3.Conclusions The AFU,ALT and GGT activity of HBVinfected persons should be detected at the same time,and evaluate the damage of liver cells.This will do help to predict the progression of hepatitis.

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).

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.

AIM:To investigate the changes of Wnt signaling pathway in catalpol-induced proliferation of rat bone marrow mesenchymal stem cells (BMSCs).METHODS:The BMSCs were isolated from SD rats , purified by differ-ential time adherent method and divided into control group and catalpol (1.0 mg/L) group.Flow cytometry was used to de-tect the proliferation index of BMSCs .The mRNA levels of Wnt3a, Wnt5a, Wnt11 and β-catenin was evaluated by real-time PCR.In addition, the protein expression level of β-catenin was determined by Western blotting .RESULTS:Prolife-ration index was increased from 8.90%±0.46% to 17.93%±1.68% after treatment with catalpol (P<0.01).Com-pared with control group , the mRNA expression of Wnt5a, Wnt11 andβ-catenin was all increased with catalpol treatment . No difference of Wnt3a mRNA expression between control group and catalpol group was observed .Meanwhile, the protein expression of β-catenin was increased in catalpol group compared with control group .CONCLUSION:Catalpol promotes BMSCs going into the cell cycle .Classical and non-classical Wnt signaling pathways are activated in this process .

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.

Objective To explore the expression levels of RAS-interacting protein 1 (RASIP1) mRNA and protein in hepatocellular carcinoma (HCC) tissues and its cell lines,and to analyze the relationship between RASIP1 and tumorigenesis and progression of hepatocellular carcinoma.Methods The expression levels of RASIP1 mRNA and protein in 29 hepatocellular carcinoma tissues and the corresponding adjacent non-cancer liver tissues (ANLTs),as well as those in the HCC cell lines such as LO2,HEPG2,MHCC97-H and HCCLM3 were detected using real-time PCR and western blot.Results The RASIP1 expression levels decreased significantly in HCC tissues when compared with the corresponding ANLTs; The expression levels of RASIP1 mRNA and protein in LO2 were significantly higher than those in other HCC cell lines (P ＜ 0.05) ; The expression levels of RASIP1 mRNA and protein in MHCC97-H and HCCLM3 were significantly lower than those in HepG2 (P ＜ 0.05).Conclusions HCC tissues had lower expression than those in ANLTs.On analyzing the RASIP1 levels of HCC tissues and its cell lines,we speculated that RASIP1 might suppress recurrence and metastasis of HCC.

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.
