AIM: To observe the effect of oxymatrine on sodium channel in isolated cardiomyocytes of guinea pig. METHODS: Single ventricular myocytes of guinea pigs were obtained by enzymatic dissociation. The whole - cell patch clamp recording technique was used to record the change of sodium current by different dosage of oxymatrine from 1 to 1 000 ?mol?L-1 . RESULTS: Oxymatrine decreased sodium current in a dose - dependent manner. Oxymatrine (100 ?mol?L-1) decreased the current density by 40% (P

The apparatus for intrinsic dissolution test recorded in United States Pharmacopeia (USP) integrating with fiber-optic drug dissolution test system (FODT) were used to real-time monitor intrinsic dissolution processes of alliin in four media which were water, solution of HCl with pH 1.2, buffer solution of acetate with pH 4.5, and buffer solution of phosphate with pH 6.8. The intrinsic dissolution rate (IDR) and the similarity factor (f2) of two intrinsic dissolution curves with two apparatuses were calculated. The IDR values of alliin with rotating disk system were 28.1.3, 33.55, 28.38 and 30.95 mg x cm(-2) x min(-1) in four media, respectively. And the IDR values of alliin with stationary disk system were 44.16, 47.07, 45.11 and 51.34 mg x cm(-2) x min(-1), respectively. The similarity factors were 56.42, 50.75, 40.30 and 40.64, respectively. The results showed that the intrinsic alliin dissolution rates were much greater than 1 mg x cm(-2) x min(-1). It inferred that alliin dissolution would not be the rate limiting step to absorption.

AIM:To investigate the effect of atorvastatin on myocardial apoptosis , ventricular remodeling and cardiac function after acute myocardial infarction (AMI) in diabetic rats, and to explore whether the effect is mediated by hepatocyte growth factor ( HGF)/c-Met signaling pathway .METHODS:Diabetes in 70 male SD rats was induced by in-traperitoneal injection of streptozotocin (STZ, 65 mg/kg).After 8 weeks, AMI was induced by the ligation of the left ante-rior descending coronary artery in the diabetic rats , and 32 surviving rats were divided into AMI group (n=16) and AMI+atorvastatin group ( n=16, 20 mg· kg -1 · d-1 ) at random.The similar surgical procedure was completed in sham group (n=11) without coronary ligation.Atorvastatin was given daily by gavage from the first day after AMI .Two weeks later, the cardiac function , pathological changes of myocardial tissues , myocardial apoptosis , and the expression of HGF and c-Met were compared among groups .RESULTS: AMI significantly reduced cardiac function , increased collagen volume fraction ( CVF) and myocardial apoptotic index , and up-regulated the expression of HGF and c-Met at mRNA and protein levels in AMI control group (P<0.05).The cardiac function was improved , and CVF and myocardial apoptotic index were reduced by the treatment with atorvastatin , which also up-regulated the expression of HGF and c-Met (P<0.05).CON-CLUSION:Atorvastatin significantly attenuates myocardial apoptosis and cardiac remodeling , and improves cardiac func-tion after AMI in diabetic rats by further enhancing the activation of HGF /c-Met pathway .

Objective To find an effective CT-MRI image fusion protocol in brain tumor by analyzing the registration accuracy of different methods. Methods The simulation CT scan and MRI T1 WI imaging of 10 brain tumor patients obtained with same position were registered by Tris-Axes landmark 、Tris-Axes landmark + manual adjustment、 mutual information and mutual information + manual adjustment method. The clinical tumor volume (CTV) were contoured on both CT and MRI images respectively. The accuracy of image fusion was assessed by the mean distance of five bone markers ( d1-5 ), central position of CTV ( dCTV ) the percentage of CTV overlap ( PCT-MRI ) between CT and MRI images. The difference between different methods was analyzed by Freidman M non-parameter test. Results The difference of the means d1-5 between the Tris-Axes landmark、Tris-Axes landmark plus manual adjustment、mutual information and mutual information plus manual adjustment methods were 0. 28 cm ±0. 12 cm, 0. 15 cm ±0.02 cm, 0. 25 cm± 0. 19 cm, 0. 10 cm ± 0. 06 cm, ( M = 14. 41, P = 0. 002 ). the means dCTV were 0. 59 cm ± 0. 28 cm,0. 60 cm± 0. 32 cm, 0. 58 cm ± 0. 39 cm, 0. 42 cm± 0. 30 cm( M = 9. 72, P = 0. 021 ), the means PCT-MRI were 0.69% ±0. 18%, 0.68% ±0. 16%, 0.66% ±0. 17%, 0.74% ±0. 14% (M = 14.82,P=0.002),respectively.

Objective:To identify the cerebral activation patterns associated with the processes that occur during viewing Chinese and English words in native Chinese English learners.Methods:12 right-handed Chinese English hamers were divided into two groups equally,namely English majors and non-English majors,and took semantic judgement tasks of both English and Chinese words,for whom the fMRI images were coUected.Results:To various degrees,all subjects demonstrated activation of associated cerebral regions in both hemispheres and the left hemisphere activation was more significant for most subjects.Except for elassieal regions involved in language processing,such as Wemicke areas and Broca areas,there were other activated cerebral regions,including cerebellum,limbic system and basal ganglia nucleus,etc.To sum up,there were apparent overlap for cerebral activation distribution and no specific processing areas for both tasks.The analysis of ROI(region of interest)suggested that subjects in specialized group were more dependent on right hemisphere to perform English words task.Conclus/on:Language cognition is dominated by left hemisphere,which is also shared by the right hemisphere to various degrees and thus two hemispheres work by ways of both dissociation and coordination.It is possible that working strategy of the right hemisphere in English task is related to proficiency of the second language.A variety of distinctions are shared by each subject for language cognitive patterns.
