Objective To explore the influence from I Ching perception of febrile disease theory to the syndrome differentiation and treatment of Viral myocarditis.Methods Documentary study.Results The febrile disease theory gained certain reference from simple ontology and motion concept in ancient Chinese philosophy.VMC was caused by disorder of five evolutive phases and six climatic factors,transition from Kan diagram to Li diagram,together with the mixture of pathogenic qi.Treatment should mainly focus on eliminating pathogen and nourishing yin to coordinate water and fire,conforming to universe rules,and smoothing Qi to reduce blockage.Conclusion The cognitive perception,pathogenesis and treatment of febrile disease theory are all deeply influenced by I Ching.Therefore,the combination of I Ching and febrile disease theory in diagnosis and treatment of VCM will improve clinical effects,as well as featuring the cultural nature of Traditional Chinese Medicine.

To evaluate the effect of bFGF on the calcium influx in SGCs and its antagonistical effect on streptomycin. The SGCs of guinea pig were isolated using an enzyme machine methods and loaded with 10?mol/L Fluo 3/AM for 30 min at 37℃,then cultured 60min at room temperature. Individual Fluo 3 loaded SGCs were examined with a confocal microscope (ACAS Ultima, USA) using a 20 x objective lens and linear scan mean.The level of SGCs[Ca 2+ ] i was steady within the process of normal extracellular liquid perfusion. SGCs[Ca 2+ ] i was increased when SGCs were perfused with 150mmol/L high potassium media(10/10) and normal media containing 1nmol/L bFGF(8/9), but the level of SGCs[Ca 2+ ] i did not change in high potassium free calcium media(9/9) and free calcium media containing 1nmol/L bFGF(10/11). After the treatment with 1 mmol/L streptomycin, the level of SGCs[Ca 2+ ] i was increased 1/11 and 5/12, respectively, when perfused high potassium media and bFGF media. And after being treated with 1nmol/L bFGF, high potassium media, SGCs[Ca 2+ ] i was increased more obviously and persisted for a longer time. After being treated with 1 mmol/L streptomycin, 0 1nmol/L, 1nmol/L and 10nmol/L bFGF, respectively, and 14/14 the level of SGCs[Ca 2+ ] i was increased 5/11, 9/12, and 14/14 when perfused high potassium media. High potassium media and bFGF perfusion could result in an increase of SGCs[Ca 2+ ] i ,and SGCs[Ca 2+ ] i increase was the result of calcium influx, and there was a synergic effect between high potassium and bFGF. Streptomycin could block the process of calcium influx induced by high potassium media, the blocking effect could be antagonized by bFGF, and the antagonistic effect was bFGF concentration dependent.

The manipulation and direct mechanical measurement of single DNA molecule could give much information about its elastic properties. Single stranded DNA (ssDNA) of 100 bases was adsorbed onto flat gold surface fabricated by depositing gold onto mica surface. Atomic force microscope (AFM) was used to observe the surface topography with different ssDNA concentration. Then the ssDNAs were stretched by AFM tip and in 50% cases ssDNAs could be stretched.Various kinds of force curves have been observed due to the different interaction between AFM tip and ssDNAs.
