In order to study on the theory of " phlegm and blood stasis having same source" and effects of drugs for resolving phlegm on blood rheology, effects of Ban Xia, Gua Lou, Zhe Bei Mu and Shi Chang Pu on whole blood viscosity, erythrocyte deformation index and plasma fibrinogen content in normal rats. Results indicated that the drugs.for resolving phlegm had functions of decreasing whole blood viscosity, inhibiting hemoagglutination (except Gua Lou) and increasing capability of erythrocyte deformation; at high shearing rate, Shi Chang Pu and Zhe Bei Mu could slightly increase whole blood viscosity: Shi Chang Pu increased slightly plasma fibrinogen content. It is suggested that resolving phlegm also can removing blood stasis, and the mechanism of the drug for resolving phlegm in decreasing blood viscosity is related with decrease of blood lipids and anti - peroxidation of lipids.

This review focuses on the fetal origins of adult disease hypothesis put forward by David Barker and his colleagues,recent advances in epidemiological studies and experimental research in this field.Barker Hypothesis states that environmental factors,particularly intrauterine nutrition,as indicated by birth weight,operate in early life to program the risks for adverse health outcomes in adult life.A large growing body of reports described the association between the early development and adult diseases,such as diabetes,hypertension,coronary heart disease,abnormal lipids metabolism,obesity and cancer,etc.Experimental studies show that the changes of some key genes' expression,caused by epigenetic modifications,lead to a permanent alteration of cellular proliferation and differentiation and finally the genesis in key tissues and organs.These results bring about the impairment in structures and functions and the increased susceptibility to chronic diseases in adult life.The hypothesis provides a new perspective for the prevention and therapy of chronic diseases.

BACKGROUND:It is reported that tailless-like protein (TLX) plays critical roles in the regulation of early developmental processes in vertebrates, and it plays a key role in stem cells proliferation and differentiation into neurons. OBJECTIVE: To construct recombinant plasmid pEGFPN1-TLX and study the transfection into dermal multipotential stem cells. DESIGN, TIME AND SETTING: Cytogene experiment was performed at the Department of Pathogen Biology, School of Basic Medical Science, the Third Military Medical University of Chinese PLA from March to December 2007. MATERIALS: An adult SD was obtained from the Experimental Animal Center of the Third Military Medical University of Chinese PLA; dermal moltipotential stem cells (DMSCs) were cultured by the Institute of Combined Injury of the Third Military Medical University of Chinese PLA; pEGFPN1 and DH5α was gifted by professor Xu.METHODS: Total RNA was extracted from rat brain tissue to amplify TLX-coded cDNA sequence using RT-PCR. T/A was cloned on pMD18-T vector and determined using BamHI and Hindlll. The products were positive recombinant plasmid pMD18-T-TLX segments, which were sub-cloned in pEGFPN1 to construct recombinant plasmid pEGFPN1-TLX. Finally, pEGFPN1-TLX was transfected into DMSCs.MAIN OUTCOME MEASURES: The fluorescence protein expression was observed under fluorescence microscope at 24 hours after transfection; TLX mRNA expression was detected using RT-PCR; neuronal differentiation was observed using immunohistochemical staining.RESULTS: TLX full length cDNA was successfully cloned into pEGFPN1, and pEGFPN1-TLX was successfully constructed by means of sequence analysis and enzyme cutting identification. As compared with non-transfected DMSCs, pEGFPN1-TLX transfected DMSCs were observed after 10 days, formed resistant clones after 15 days, and shown a green fluorescent protein expression. However, non-transfected DMSCs died at day 10. RT-PCR indicated that pEGFPN1-TLX transfected DMSCs could express TLX mRNA. At day 3 after induction, NF200 positive cells were increased, but glial fibrillary acidic protein positive cells were decreased after induction of pEGFPN1-TLX transfected DMSCs.CONCLUSION: TLX was successfully constructed and transfected into DMSCs. After transfection, neuronal differentiation of DMSCs was enhanced, and the differentiation to gliocytes was inhibited.

Objective To prospectively evaluate the sensitivity and specificity of ankle brachial index (ABI) in the diagnosis of lower extremity arterial disease(LEAD)by using conventional digital subtraction angiography (DSA) as the reference standard, and to research the threshold value of ABI screening test for diagnosis. Methods A total of 383 consecutive patients (245 men and 138 women, mean age (64.1±11.7) years] underwent conventional DSA and ABI measurement. Receiver operator characteristics (ROC) analysis was performed to assess possible threshold values for predicting the LEAD in these patients. Results Conventional DSA was used as the gold standard in defining≥50% luminal stenosis for the diagnosis of LEAD. 0. 95 was the overall cutoff of ABI which was associatcd with 93.0% sensitivity, 85.0% specificity, 8.81 positive likelihood ratio(+LR) and 0. 23 negative likelihood ratio(-LR) for detection of hemodynamically significant stenosis (lesions>≥50%) in all 383 subjects (P<0.01). The area under the ROC curve was 0. 953(95%CI 0.920~0.985). Conclusions ABI measurement is an accurate and reliable non-invasive alternative to conventional DSA in the diagnosis of lower extremity arterial disease. And the cut-off 0.95 is the threshold ABI value for detecting LEAD in Chinese population.
