Objective To observe the effects of neuregulin‐1 (NRG‐1)on calcium transients in mouse ventricular myo‐cytes.Methods Nine C57BL/6 mice of male were randomly dived into 3 groups :the blank control group ,NRG‐1 group ,and iso‐proterenol(ISO)group.Their hearts were removed and immediately cannulated via the aorta and retrogradely perfused with en‐zymatic isolation solution to get single ventricular cell by Langendorff system.Myocytes were loaded with the Ca2+ indicator Fluo‐4 and subjected to electrical field stimulation at 0.5 or 1 Hz by using living cells workstation.The change of fluorescene in‐tensity was recorded simultaneously in each group.Results Compared with the blank control group ,NRG‐1 group had signifi‐cantly increased Ca2+ transient amplitude ΔF/F0 (n=10 ,P<0.05) ,and reduced Ca2+ transient recovery time RT50 (n=10 ,P<0.05).There were no significant differences in Ca2+ transient amplitude ,Ca2+ transient recovery time and the time to peak be‐tween NRG‐1 and ISO groups(n=10 ,P>0.05).Conclusion NRG‐1 can increase Ca2+ transient amplitude and Ca2+ transients and reduce the time interval of Ca2+ transients.

OBJECTIVE:To investigate the pharmacokinetic profiles of baicalin(a constituent in Sanhuang decoction) in rats.METHODS:Blood samples were collected as schedule from rats after intragastrically administration of Sanhuang decoction, then the content of baicalin was determined by HPLC and the chief pharmacokinetic parameters were computed.RE SU1TS:The chief pharmacokinetic parameters of baicalin in rats were as follows:t_(max1)=(15?4.23) min;t_(max2)=(6.8?0.54) h;C_(max1) =(4.49?1.56)?g?mL~(-1);C_(max2)=(3.25?1.23)?g?mL~(-1);AUC =(35.52?12.35)?g?h?mL ~(-1);t_(12)=(5.12?0.23)h;CL=(3.86?0.91) 1?h~(-1).CONCLUSION:The method is simple in sample treatment,rapid and accurate,specific and sensitive,and it can be used as a means for the monitoring of the serum concentration of baicalin containing Chinese patent medicines and so as to provide reference for clinical rational drug use.

There is a regular pattern in the diagnosis and treatment of exogenous high-grade fever, of which the key point is formula syndrome identification. Syndrome differentiation of the six channels is appropriate for not only exogenous cold but also various other conditions. The diagnosis and treatment of high-grade fever can also follow the law of syndrome differentiation of the six channels. The theory of epidemic febrile diseases stems from and elaborates on an understanding of exogenous febrile conditions, so many effective formulas used to treat epidemic febrile diseases also have great value in the treatment of high-grade fever. Deteriorated syndrome, which is central to this condition, is very commonly seen in cases of high-grade fever, the key therapeutic principle of which is established according to syndromes. Allowing analysis that does not rigidly adhere to either established modern diagnosis or traditional Chinese syndromes, prominent achievements could be made in treating high-grade fever by summarizing the regular presenting patterns in terms of the constitution and symptoms.

BACKGROUND:Stem cells under appropriate conditions can be induced to differentiate into neuron-like cells. Chinese herbs can function in cellproliferation and differentiation.
OBJECTIVE:To investigate the interventional effects of traditional Chinese medicine on stem celltransplantation in the treatment of cerebrovascular diseases.
METHODS:Experimental studies concerning traditional Chinese medicine intervention for stem celltransplantation were retrieved and analyzed. Under specific conditions, stem cells can proliferate in vitro in a suspended or monolayer manner, and can be potential y induced to differentiate into neurons, oligodendrocytes and astrocytes, thereby providing basis for stem celltransplantation in the treatment of cerebrovascular diseases. We observed expressions of nestin, glial fibril ary acidic protein, and microtubule-associated protein expression for analysis of stem cellproliferation and differentiation.
RESULTS AND CONCLUSION:Baicalin or Astragalus saponin Ⅳ can stimulate stem cells to differentiate into nerve cells in vitro. Naomaitong or danshen combined with bone marrow mesenchymal stem celltransplantation can promote neurological recovery from cerebrovascular diseases in rats. Buyang Huanwu Decoction can significantly promote the proliferation of neural stem cells in the subventricular zone and neurological recovery after cerebral ischemia. Chinese herbs, such as Zhichan Decoction and Panax notoginseng, can promote survival of transplanted cells and prevent most cellapoptosis in the stem celltherapy for treatment of Parkinson’s disease. Therapy of benefiting qi and elevating yang or ginsenosides Rg1 combined with stem celltherapy can improve memory ability of dementia rats. Traditional Chinese medicine exerts a catalytic role in the stem celltherapy for cerebrovascular diseases.

Objective: To investigate the effect and mechanism of liraglutide on vasodilatation of thoracic aortic ring in experimental rats.
Methods: The thoracic aortic rings were isolated from 32 male SD rats and divided into 2 groups: Without endothelium group and With intact endothelium group, n=16 in each group. The contractile force of vascular ring was detected and the effect of liraglutide (1×10-5 mol/L) on vasodilatation of norepinephrine (NE, 1×10-6 mol/L) pre-contracted ring was observed. The aortic ring in With intact endothelium group was further divided into 2 sub-groups:①the aortic ring was pre-treated by the inhibitor of nitric oxide synthase (NOS) (L-NAME at 10-4 mol/L),② the aortic ring was pre-treated by non-specific ATP-sensitive-potassium (KATP) channel (Glibenclamide at 10-5 mol/L), n=8 in each group. The impacts of liraglutide on those 2 sub-groups were studied.
Results: Liraglutide had no effect on isolated aortic ring at basic condition. Liraglutide at (10-5 mol/L) had vasodilatation effect in both Without endothelium and With intact endothelium groups, the effect was stronger in With intact endothelium group and the maximum vasodilatation reached 17%, P<0.05. In both pre-treated sub-groups, the effect of liraglutide on vasodilatation in sub-group①reached 4%, P<0.05, and the effect in sub-group②
reached 14%, P>0.05.
Conclusion: Liraglutide had obvious effect of vasodilatation on NE pre-contracted thoracic aortic ring in experimental rats, the mechanism might be related to NOS, while KATP channel could not block the vasodilatation effect of liraglutide.
