OBJECTIVE: To investigate the clinical features of primary biliary cirrhosis (PBC) and its treatment by integrated traditional Chinese and western medicine. METHODS: 16 PBC patients were observed. Ursodeoxycholic acid (UDCA) was used in the dose of 13 to 15 mg.kg(-1).d(-1), with some traditional Chinese herb prescription. Results (1) The proportion of women to men was 15:1, the mean age was 52.5 years. AMA-M2 was positive in 14 subjects (87.5%). Biliary tract enzymes and ESR were elevated in all subjects. The ratio of hypercholesterolemia (CHOL) and abnormality in IgM was high (62.5%). Fatigue, pruritus, arthralgia, jaundice, splenomegaly were noted in more than half cases. Every patient had one to four complications. (2) ALP, GGT and Glb declined evidently after 3 months' treatment by western medicine associated with traditional Chinese medicine, and declined markedly after 12 months' treatment (P<0.05 respectively). TBIL and CHOL declined gradually during the treatment course. Symptoms and signs were lightened. CONCLUSION: PBC has complicated and especial clinical features. UDCA therapy is effective in PBC, while traditional Chinese medicine has extraordinary effect in treating the symptoms and signs.

The property theory of Chinese herbal medicine (CHM) is regarded as the core and basic of Chinese medical theory, however, the underlying mechanism of the properties in CHMs remains unclear, which impedes a barrier for the modernization of Chinese herbal medicine. The properties of CHM are often categorized into cold and heat according to the theory of Chinese medicine, which are essential to guide the clinical application of CHMs. There is an urgent demand to build a cold/heat property classification model to facilitate the property theory of Chinese herbal medicine, as well as to clarify the controversial properties of some herbs. Based on previous studies on the cold/heat properties of CHM, in this paper, we described a novel strategy on building a cold/heat property classification model based on herbal bio-effect. The interdisciplinary cooperation of systems biology, pharmacological network, and pattern recognition technique might lighten the study on cold/heat property theory, provide a scientific model for determination the cold/heat property of herbal medicines, and a new strategy for expanding the Chinese herbal medicine resources as well.

Objective To investigate the molecular mechanism underlying lymphocyte functionassociated antigen-1 (LFA-1) / intercellular adhesion molecule-1 (ICAM-1) mediated anti-neoplastic effects of cytokine induced killer (CIK) cells. Methods Lymphocytes isolated from peripheral blood of children leukemia were induced with interferon-gamma (IFN-y), anti-CD3 monoclonal antibody (CD3McAb) and interleukin-2 (IL-2) and co-cultured with dendrite cells (DC) to generate DC-CIK cells. When treated with LFA-1 monoclonal antibody, cytotoxicity of DC-CIK cells against leukemia cell lines was measured by the MTT assay, while RT-PCR and Western blotting were used to determine mRNA and protein expressions of GATA-3 and T-bet in DC-CIK cells, respectively. IL-12, IFN-γ and tumor necrosis factor-α (TNF-α) levels released by DC-CIK cells were quantified by ELISA. Results Induced DC-CIK cells were regular, round and transparent with variable cell volume and cellular aggregation. When treated with mouse anti-human LFA-1 monoclonal antibody, the cytotoxicity decreased mostly towards B95 cells under administration of 20 μg/ml LFA-1 monoclonal antibody in comparison with the control group(t =10.138, P ＜0.05). It led to a highest elevation of GATA-3 mRNA and protein levels (t =16.386, P ＜ 0.05; t =22.652, P ＜ 0.05) and a most decrease of T-bet mRNA and protein levels (t =17.728, P ＜0.05; t =17.452, P ＜0.05) under 20 μg/ml LFA-1 monoclonal antibody in B95 cells group in comparison with the control group. The expression levels of IL-12,IFN-γ, and TNF-o in supernatant were the lowest under 20 μg/ml LFA-1 monoclonal antibody in B95 cells group in comparison with the control group (t =21.621, P ＜0.05; t =13.739, P ＜0.05; t =15.278, P ＜0.05).Conclusion GATA-3 and T-bet were implicated in the LFA-1/ICAM-1 mediated anti-neoplastic effects of DC-CIK cells via activation of the Th1 pathway, with high secretion of Th1 cytokines, such as IL-12, IFN-γ and TNF-α.
