China Journal of Traditional Chinese Medicine and Pharmacy 2005;0(08):-
Type 2 Diabetes Mellitus(T2DM) is classified as two types according to somatotype,one is obesity or overweight,the other is normal or emaciation.It can also be classifi ed as two types according to symptoms,one is accompanied with typical syndromes(polyuria,polydipsia,polyphagia and weight loss),the other one is not.Generally speaking,the typical syndrome is not obvious among the patients with obesity or overweight,which is coincident with the theory about stuffy and fully sensation in the middle energizer and interior heat mentioned in emperor’s internal classic.So the therapeutic method is regulating the function of the middle energizer,evacuating full and stagnation,resolving phlegm and removing pathogenic heat.The typical syndrome is obvious among the patients with normal bodily form or emaciation,which is according with the traditional theory about defi ciency of yin and dryness-heat.So the therapeutic method is nourishing yin and clearing heat.The two types above are absolutely different.

BACKGROUND:It is discovered recently that miRNA is a new regulator that is able to have an impact on gene expression and miRNA contributes to proliferation, differentiation and self-renewal of pluripotent stem cels.
OBJECTIVE:To investigate the mechanism by which miR-155 regulates chondrogenic differentiation of bone marrow mesenchymal stem cels.
METHODS: Sixty healthy Sprague-Dawley aged 12 weeks were randomized into study group and control group, with 30 in each group. Under anesthesia, rats were sacrificed to harvest bone marrow of the lower limbs. Then bone marrow mesenchymal stem cels were isolated, cultured, and transfected with miR-155 mimics in the study group and a negative control sequence in the control group. After chondrogenic induction, RT-PCR was used to detect the expressions of Sox9, Colagen II, Aggrecan and Colagen X gene, and western blot assay to detect the expression of Sox9 and Runx2 proteins.
RESULTS AND CONCLUSION:Compared with the control group, the mRNA expressions of Sox9, Colagen II and Aggrecan were higher, but the mRNA expression of Colagen X was lower in the study group (P < 0.05); the protein expression of Sox9 was higher, but the protein expression of Runx2 was lower in the study group (P < 0.05). These findings indicate that miR-155 promotes the chondrogenic differentiation of bone marrow mesenchymal stem cels and moreover, it can suppress the hypertrophy trend of bone marrow mesenchymal stem cels differentiating into chondrocytes.

AIM: To investigate the effects of antagonistic peptide specifically binding to the second extracellular loop of CC chemokine receptor 5 (CCR5) on inflammatory cell infiltration and TNF-α expression in lung tissues of asthmatic mice.METHODS: The asthmatic model of BALB/c mice was induced by ovalbumin (OVA) and the optimal sensitization concentration of OVA was screened.After modeling, the mice were intervened by gradual concentrations of antagonistic peptide via tail-vein injection.The pathocytological analysis and grading were performed in the lung tissues with HE staining.The expression of TNF-α at mRNA and protein levels in the lung tissues was determined by real-time PCR and Western blot.RESULTS: The optimal concentration of OVA was 500 mg/L (0.1 mL) as this concentration of OVA stably induced moderate degree of inflammation in the BALB/c mice.Treatment with different concentrations (1.5 g/L, 2.5 g/L and 3.5 g/L) of antagonistic peptide at 0.2 mL through tail-vein injection inhibited the expression of TNF-α, and markedly reduced the degree of inflammation in the lung tissues.The optimal concentration of antagonistic peptide was 2.5 g/L as the lung inflammation degree in 2.5 g/L group alleviated by 2 grades, and the number of inflammatory cells was also significantly reduced.Moreover, the mRNA expression abundance of TNF-α was nearly decreased by 90%, and the protein expression of TNF-α was decreased by 70% compared with model group.Meanwhile, the use of antagonistic peptide at 2.5 g/L before OVA stimulation confirmed the preventive function to some degree.In this group, the lung inflammation degree alleviated by 1 grade, and the expression of TNF-α at both mRNA and protein levels decreased by nearly 50%.CONCLUSION: The antagonistic peptide of CCR5 effectively inhibits the expression of TNF-α and relieves the inflammation in the asthmatic mouse lung tissues in a concentration-dependent manner.

The inheritance of prestigious TCM doctors' experiences is not only important for improving the level of health protection and developing the academic level of TCM in our country, but also an urgent research topic that need to be worked on. In this paper, the contents and methods of research on the inheritance of prestigious TCM doctors' experiences are discussed. There are three main research issues: the clinical experiences, the academic thoughts, and the ethics of prestigious TCM doctors. And when doing research on the methods, these problems should be paid attention to: study prestigious TCM doctors' clinical experiences, academic thoughts and ethics at the same time; start the research with trying to find a doctor's own character by comparison; understand the origin and development of a doctor's academic thought from the culture background; pay attention to the process of making tacit knowledge explicit; do more researches on the evaluation, promotion and application of prestigious TCM doctors' experiences based on EBM (evidence-based medicine).
