Methods： Ninety ACS patients were randomized into two groups, the control group treated with conventional therapy and the SMI group treated with SMI. The patients＇ cardiac function was noted and the content of high sensitive C-reactive protein （hs-CRP） in venous blood was measured before treatment and 1 week and 3 weeks after treatment, so as to observe and compare their changes between the two groups. Results： The cardiac output, stroke volume and ejection fraction in the SMI group after 3 weeks of treatment were all higher than those in the control group （P〈0.05）. The serum content of hs-CRP was reduced in both groups （P〈0.05）, but the reduction in the SMI group was more significant than that in the control group （P〈0.05）. Conclusion： SMI could improve the cardiac function and further inhibit the inflammatory reaction in patients with ACS.展开更多

Hubei Province as a large agricultural province is significantly affected by the human capital. The paper selects the correlation data about rural economic growth in Hubei Province as samples to analyze the contribution of physical capital and human capital to rural economic growth by the new C-D function and SPSS22. 0. The results show that the effect of the elasticity of human capital is greater than that of physical capital in rural economic development; the high quality rural human capital storage and the average years of schooling of rural labor force will increase the net income of rural household. Therefore,we should not only increase input of physical capital but also increase the input of human capital to raise the level of human capital in rural areas and promote sustainable development of rural economy.展开更多

There is no indication of any phasetransition or thermal anomaly in this temperature region for the present compound. Theresults have been compared with those reported in [1] in the overlapping temperaturerange. The experimental heat capacity data have been fitted to a smoothed curve by the aidof the effective frequency distribution method, and the heat capacities below 13K have beenobtained by extrapolating the fitting curve down to 0K. The standard molar thermodynamicfunctions between 0 and 400 K have been derived by combining the present heat capacitymeasurements with the previous ones. The values of C_p^o (T), S^o(T) - S^o(0), [H^o(T) -H^o(0)]/T, and - [G^o(T) - H^o(0)]/T at T = 298.15 K are 189.35, 244.60, 112 .45 and 132.15J·K^(-1)·mol^(-1), respectively.展开更多

MicroRNAs（miRNAs） are a class of endogenous 18–24 nucleotide（nt） non-coding RNAs, some of which have been shown to be important regulators of GCs function. miR-34c involved in the regulation of various biological processes and was identified to be a pro-apoptotic and anti-proliferative factor in many cell types. However, the roles of miR-34c in GCs function remain unknown. In this study, we used Annexin V-FITC and Ed U assays to demonstrate that miR-34c exerted pro-apoptotic and anti-proliferative effects in porcine GCs. Dual-luciferase reporter assays, quantitative real-time PCR（q RT-PCR） and Western blotting identified Forkhead box O3a（Fox O3a） as a direct target gene of miR-34c. The overexpression of FoxO3a rescued the phenotypic change caused by miR-34c in porcine GCs. In conclusion, miR-34c regulate the function of porcine GCs by targeting FoxO3a.展开更多

Upon the optimization on different adsorption sites with coverage of 1/20 and 1/5 ML,it was found that the adsorption of C atoms on the α-Fe2O3（001） surface was chemical adsorption. The coverage can affect the adsorption behavior greatly. Under low coverage,the most stable adsorption geometry lied on the bridged site with the adsorption energy of about 3.22 eV; however,under high coverage,it located at the top site with the energy change of 8.79 eV. Strong chemical reaction has occurred between the C and O atoms at this site. The density of states and population analysis showed that the s,p orbitals of C and p orbital of O give the most contribution to the adsorption bonding. During the adsorption process,O atom shares the electrons with C,and C can only affect the outermost and subsurface layers of α-Fe2O3; the third layer can not be affected obviously.展开更多

We previously found that neural control of vasomotor activity could be potentially harnessed to evaluate nerve function. In the present study, five different models of left sciatic nerve injury in rats were established: nerve crush injury, nerve transection/ suturing, nerve defect/autografting, nerve defect/conduit repair, and nerve defect/non-regeneration. Laser Doppler perfusion imaging was used to analyze blood perfusion of the hind feet. The toe pinch test and walking track analysis were used to assess sensory and motor functions of the rat hind limb, respectively. Transmission electron microscopy was used to observe the density of unmyelinated axons in the injured sciatic nerve. Our results showed that axonotmesis-evoked vasodilatation in the foot 6 months after nerve injury/repair recovered to normal levels in the nerve crush injury group and partially in the other three repair groups;whereas the nerve defect/non-regeneration group exhibited no recovery in vasodilatation. Furthermore, the recovery index of axonotmesis-evoked vasodilatation was positively correlated with toe pinch reflex scores and the density of unmyelinated nerve fibers in the regenerated nerve. As C-fiber afferents are predominantly responsible for dilatation of the superficial vasculature in the glabrous skin in rats, the present findings indicate that axonotmesis-evoked vasodilatation can be used as a novel way to assess C-afferent function recovery after peripheral nerve injury. This study was approved by the Ethics Committee for Laboratory Animals of Nantong University of China (approval No. 20130410-006) on April 10, 2013.展开更多
