Rabbits w...The transmural heterogeneous changes of transient outward potassium currents (Ito) in rabbit hypertrophic cardiaomyocytes and the effects of long-term prophylactic treatment with volsartan were investigated. Rabbits were divided into hypertrophy group (left ventricular hypertrophy induced by partial ligation of abdominal aorta), vol-treated group (volsartan was administrated after the ligation), and control group (sham operated). Myocytes were isolated by a two-step enzymatical method. The sub-endocardial (Endo) and sub-epicardium (Epi) tissues were separated from midmyocardium (Mid) with a razor. Whole-cell patch-clamp technique was used to record potassium currents. The results showed that membrane capacitance was larger in hypertrophic cells than those in control and vol-treated cells (P<0.01 vs control cells, n=30). The densities of Ito in hypertrophic cells were reduced by sub-epicardium (Epi) (27.8±2.9) %, midmyocardium (Mid) (41.0±4.7) %, and sub-endocardium (Endo) (20.3±3.4) % compared with those in control cells. The decrease of Ito density was more pronounced in Mid than in Epi and Endo (P<0.01 vs Epi or Endo). There were no significant differences in Ito densities between vol-treated group and control group in three layers separately. In conclusion, volsartan can inhibit the transmural heterogeneous changes of Ito in left ventricular hypertrophic cardiomyocytes in rabbit.展开更多

文摘The Chuan-Dian Block(CDB)is located in the southeastern margin of the Tibetan Plateau,with a complex geological structure and active regional faults.The present tectonic condition with strong crustal deformation is closely related to the ongoing collision of the India and Eurasia plates since 65 Ma.The study of the crustal structure of this area is key to revealing the evolution and deep geodynamics of the lateral collision zone of the Tibetan Plateau.Deep seismic sounding is the most efficient method with which to unravel the velocity structure of the whole crust.Since the 1980s,19 deep seismic sounding profiles have been captured within the CDB area.In this study,we systematically integrate the research results of the 19 profiles in this area,then image the 3D crustal velocity,by sampling with a 5 km spacing and 2D/3D Kriging interpolation.The results show the following.(1)The Moho depth in the study area deepens from 30 km in the south to 66 km in the north,whereas there is no apparent variation from west to east.The Pn wave velocity is higher in stable tectonic units,such as 7.95 km/s in the Lanping-Simao block and 7.94 km/s in the western margin of the Yangtze block,than in active or mobile tectonic units,such as 7.81 km/s in the Baoshan block,7.72 km/s in the Tengchong block and 7.82 km/s in the Zhongdian block.(2)The crustal nature of the Tengchong block,the northern Lanping-Simao block and the Zhongdian block reflects a type of orogenic belt,having relatively strong tectonic activities,whereas the crustal nature of the central Lanping-Simao block and the western margin of the Yangtze block represents a type of platform.The different features of the upper-middle crust velocity,Moho depth and Pn wave velocity to both sides of the Red River fault zone and the Xianshuihe fault zone,reflect that they are clearly ultra-crustal.(3)Based on the distribution of the low velocity zones in the crust,the crustal material of the Tibetan Plateau is flowing in a NW–SE direction to the north of 26°N and to the west of 101°E,then diverting to flowing eastwards to the east of 101°E.

文摘With the further development of economic globalization since the establishment of ties between China and the Association of Southeast Asian Nations(ASEAN) 30 years ago and the continuous increase in the scale of international students in China,the training of international talents has become an important approach to avoiding the risks of transnational investments.We established panel data by selecting variables from the period 2006 to 2017,including the scale of international students coming from ASEAN to China,the gross amount of China’s outward foreign direct investment(OFDI),and the GDP per capita of ASEAN countries to further explore the correlations among these variables.We applied a panel-vector autoregressive(PVAR) model to conducting a Granger causality test,a Gaussian mixture model(GMM) regression analysis,a Monte Carlo-based impulse response analysis,and variance decomposition of the data.The results show that the growth of OFDI exerted an obvious positive impact on the inflow of international students from the countries along the Belt and Road(B&R) within a short period,the growth of the scale of international students coming from these countries to study in China had a strong positive effect on OFDI,the training of international talents was conducive to promoting the scale of transnational investments,but the overall quality was not very high,and its economic contribution rate was low.It is also found that OFDI and the scale of international students from the countries along the B&R promoted the GDP growth to a certain extent and the positive accumulation effect fluctuated due to external factors.Therefore,it is suggested to expanding the scale of OFDI and improving China’s core competitiveness in international student education.Intensive management of investment factors should also be conducted along with sound development of training mechanisms for international talents.
文摘Editor’s note:Recently,official from the Department of Outward Investment and Economic Cooperation of the Ministry of Commerce has made comments on China’s outward investment and economic cooperation as well as foreign investment in JanuaryNovember.China’s Outward Investment and Economic Cooperation In January-November 2015,China’s outward investment and cooperation maintained a sound development momentum.The direct investment
文摘Traditional foreign direct investment (FDI) theory only examines corporate investment motivation while neglectinggovernment roles.China’s outward direct investment (ODI) is of both commercial and strategic significance to leveragedomestic and international resources and markets.ODI is a corporate behavior but also is a means of achieving nationalstrategies and heightening political and economic statuses.As a source of ODI,China should provide strong guidance andbacking to corporate ODI for both commercial and national interests.
文摘The transmural heterogeneous changes of transient outward potassium currents (Ito) in rabbit hypertrophic cardiaomyocytes and the effects of long-term prophylactic treatment with volsartan were investigated. Rabbits were divided into hypertrophy group (left ventricular hypertrophy induced by partial ligation of abdominal aorta), vol-treated group (volsartan was administrated after the ligation), and control group (sham operated). Myocytes were isolated by a two-step enzymatical method. The sub-endocardial (Endo) and sub-epicardium (Epi) tissues were separated from midmyocardium (Mid) with a razor. Whole-cell patch-clamp technique was used to record potassium currents. The results showed that membrane capacitance was larger in hypertrophic cells than those in control and vol-treated cells (P<0.01 vs control cells, n=30). The densities of Ito in hypertrophic cells were reduced by sub-epicardium (Epi) (27.8±2.9) %, midmyocardium (Mid) (41.0±4.7) %, and sub-endocardium (Endo) (20.3±3.4) % compared with those in control cells. The decrease of Ito density was more pronounced in Mid than in Epi and Endo (P<0.01 vs Epi or Endo). There were no significant differences in Ito densities between vol-treated group and control group in three layers separately. In conclusion, volsartan can inhibit the transmural heterogeneous changes of Ito in left ventricular hypertrophic cardiomyocytes in rabbit.

文摘Acutely isolated mouse hippocampal CA3 pyramidal neurons were exposed to 3 mT static magnetic field,and the characteristics of transient outward K+ channel were studied using the whole-cell patch-clamp technique.The experiment revealed that the amplitude of transient outward potassium channel current was reduced.The maximum activated current densities of control group and exposure group were 163.62±20.68 pA/pF and 98.74±16.57 pA/pF(n=12,P<0.01) respectively.The static magnetic field exposure affected the activation and inactivation process of transient outward potassium channel current.Due to the magnetic field exposure,the half-activation voltage of the activation curves changed from 5.59±1.96 mV to 27.87±7.24 mV(n=12,P<0.05) ,and the slope factor changed from 19.43±2.11 mV to 25.87±4.22 mV(n=12,P<0.05) .The half-inactivation voltage of the inactivation curves also changed from-56.09±0.89 mV to-57.16±1.10 mV(n=12,P>0.05) and the slope factor of the inactivation curves from 8.69±0.80 mV to 10.87±1.02 mV(n=12,P<0.05) .The results show that the static magnetic field can change the characteristics of transient outward K+ channel,and affect the physiological functions of neurons.

文摘The electrophysiological properties of potassium ion channels are regarded as a basic index for determining the functional differentiation of neural stem cells.In this study,neural stem cells from the hippocampus of newborn rats were induced to differentiate with neurotrophic growth factor,and the electrophysiological properties of the voltage-gated potassium ion channels were observed.Immunofluorescence staining showed that the rapidly proliferating neural stem cells formed spheres in vitro that expressed high levels of nestin.The differentiated neurons were shown to express neuron-specific enolase.Flow cytometric analysis revealed that the neural stem cells were actively dividing and the percentage of cells in the S+G2/M phase was high.However,the ratio of cells in the S+G2/M phase decreased obviously as differentiation proceeded.Whole-cell patch-clamp recordings revealed apparent changes in potassium ion currents as the neurons differentiated.The potassium ion currents consisted of one transient outward potassium ion current and one delayed rectifier potassium ion current,which were blocked by 4-aminopyridine and tetraethylammonium,respectively.The experimental findings indicate that neural stem cells from newborn rat hippocampus could be cultured and induced to differentiate into functional neurons under defined conditions in vitro.The differentiated neurons expressed two types of outward potassium ion currents similar to those of mature neurons in vivo.
