Objective To investigate the differential gene expression in chronic hepatitis B (CHB) patients with typical syndromes of traditional Chinese medicine ( TCM) syndromes, and to explore the relationship between TCM syndromes and gene expression. Methods Peripheral blood samples were collected from CHB patients and healthy volunteers before treatment. After total RNA of leukocytes was isolated, the gene expression profiles were detected by microarray. The expression levels of partial genes were tested by real-time quantitative reverse transcription-polymerase chain reaction (RT-PCR) . Results Microarray analysis results showed that there were significant differences of gene expression between CHB patients and healthy volunteers, and among CHB patients with the syndrome of liver-qi stagnation and spleen deficiency, syndrome of damp-heat accumulation, and syndrome of liver-kidney yin deficiency. The results of gene ontology ( GO) and signal pathway analysis between the healthy control and CHB patients with various syndromes showed that the specially-regulated genes of CHB patients with liver-qi stagnation and spleen deficiency were mainly related to cytokinetic process, those in patients with dampness-heat accumulation were mainly related to the positive regulation of lipid storage, and those of patients with liver-kidney yin deficiency were mainly related to the activities of nitric oxide synthase regulator. The real time RT-PCR for partial genes presented the similar results with those of gene microarray. Conclusion There are specific expression profiles of differential genes and significant differential genes in CHB patients with the syndrome of liver-qi stagnation and spleen deficiency, syndrome of damp-heat accumulation, and syndrome of liver-kidney yin deficiency, which may be the molecular foundation for the classification of TCM syndromes of CHB patients.

The absorption process is an important factor in determining the bioavailability of orally administered drugs. however, the absorption mechanism of many drugs is not clear. Caco-2 cell model is the best in vitro absorption model nowadays. It is widely used in the research on drug absorption process and absorption mechanism, especially in the aspect of traditional Chinese medicine absorption, the use of Caco-2 cell model has become the hot spot recently. Mo- reover, Caco-2 cell model is also applied in the research on drug metabolism. Therefore, Caco-2 cell model will become an important method in the research of drug absorption, and will be helpful to accelerate the process of new drug screening and development.

BACKGROUND:Mesenchymal stem cells are found to have the immunoregulatory activities and a potential application prospect in the treatment of autoimmune diseases.
OBJECTIVE:To explore the mechanism of transplanting mesenchymal stems cells on the treatment of multiple sclerosis.
METHODS:The mouse mesenchymal stems cells were prepared, and injected into the al ogenic and syngenic normal mice, to detect the frequency of CD4+CD25+Foxp3+T cells in the spleen, thymus, and lymph nodes by flow cytometry, and to detect the Foxp3, transforming growth factor-β1, and interleukin-10 mRNA in the spleen, thymus, and lymph nodes by reverse transcription-PCR.
RESULTS AND CONCLUSION:Transplantation of mesenchymal stem cells on normal mice led to a significant up-regulation of CD4+CD25+Foxp3+T cells, Foxp3, transforming growth factor-β1, and interleukin-10 mRNA in the spleen, thymus, and lymph nodes both in the al ogenic and syngenic transplant groups. Transplantation of mesenchymal stem cells may be an available method in the treatment of autoimmune diseases, and CD4+CD25+Foxp3+T cell, Foxp3, transforming growth factor-β1, and interleukin-10 may be involved in this process.

Objective To analyze the airflow characteristics and investigate the relationship of the structure and the function of nasal cavity by the three?dimensional reconstruction of nasal airway of patients with structural abnormalities(nasal septum deviation)and healthy people and the estab?lishment of finite element model by computer. Methods On the basis of CT imaging of the nasal cavity in patients with structural abnormalities(na?sal septum deviation,n=20)and healthy people(n=20),three?dimensional reconstruction of nasal airway was conducted by resurfacing finite ele?ment subdivision to simulate the characteristics of airflow in nasal cavity. Results The airflow mainly went through the commodious side of the nose in patients with nasal septum deviation and the maximum fluence appeared in the middle part of meatus nasi communis. The airway pressure de?creased most significantly in the most flank?curvature part of nasal septum deviation,accounting approximately 79.65%of the total pressure. In healthy people,the bilateral airflow was affected by nasal cycle and was mainly characterized by one nasal cavity,and the maximum fluence was ob?served in the middle and the inferior part of meatus nasi communis. The airway pressure decreased most significantly in limen nasi,accounting ap?proximately 58.78%of the total pressure. Conclusion Numerical modeling of nasal cavity can be used to analyze the relationship between the nasal structural abnormalities and the airflow characteristics,which is a scientific method to analyze the association of nasal structure and function with dis?ease and can be used for pre?and post?operative individual evaluation of operative therapeutic regimen targeting at optimizing airway and altering air?flow distribution.
