Objective To study the effects of allopurinol in different dose on the cardiac function of chronic heart failure rats induced by adrimycin. To explore dose-dependency of allopurinol in improving blood vessel endothe-lium function and cardiac ventricle remodeling of the rats heart, as to supply evidence and new sight in clinical treat-ment of congestive heart failure. Methods 40 Sprague-Dawley male rats were randomly divided into four groups: normal control group (group A)、model control group (group B)、low-dose allopurinol group (group C)、high-dose allopurinol group (group D). The heart failure model was made by administering adriamycin to rats. After the model myocardial pathological changes were detected. Results Compared with the normal control group, the weight and heart weight of rats in model control group and allopurinol groups were obviously lessen (group A=(300.10± 9.85)g,group B=(200.67±9.91)g, group C=(233.14±9.42)g,group D=(248.25±13.34) g;group A= (828.30±50.97) nag, group B=(681.50±16.97) mg, group C=(743.00±17.20) nag, group D=(784.88± 36.83) mg,P<0.05). Heart weight indexes were all incerased ( group A=(2.76±0.15) mg/g, group B=(3.41± 0.17) mg/g, group C=(3.26±0.76) mg/g, group D=(3.11±0.65) mg/g, P<0.05). The hemedynamics resuh showed that myocardial contractile force were enhanced in drug groups. The level of NO, SOD were increased in the allopurinol groups compared with the model control group (group B: NO=(41.55±6.28) μmol/L, group C: NO= (52.47±5.59) μmoL/L,group D:NO=(61.04±4.26) μmoL/L; group B:SOD=(63.83±6.40) U/ml,group C: SOD=(76.29±7.99) U/ml, group D: SOD=(100.13±7.43) U/ml, P<0.05) and MDA levels were obviously decreased (group B: MDA=(9.70±1.08) μmol/L, group C: MDA=(6.64±0.34) μmol/L, group D: MDA= (5.72±0.71)p.moVL,P<0.05). The level of NO, SOD were obviously increased in the allopurinol of high-dose group compared with low-dose allopurinol group(P<0.05). MDA levels were obviously decreased(P<0.05). The myocardial pathological changes were relieved obviously in the allopufinol groups. Conclusion Allopurinol improves blood vessel endothelium function dose-dependently. High-dese allopurinol obviously decreases MDA, improve NO, SOD, thereby can improve the cardiac function of heart failure.

Objective To study the influence of Noradrenergic systems in Lateral Hypothalamus Area (LHA) on small intestine moving. Methods The effect of noradrenalin、noradrenalin+phentolamine、noradrenalin+propolol、phentolamine on small intestines electro-activity of rats was detected by external alimentary canal electrodes and central nervous system stereo-configuration technology. Results After injecting 2 g/L noradrenaline (NE) the cyclic period of MMC extended, the ratio of the active time to the cyclic period and the number of the fast wave within the active time per minute reduced. NE inhibited the electro-activity of small intestine of rats, and the average effective time was (36.86?7.39)min. Hence injecting 5 g/L PE alone to LHA raised the ratio of the MMC active time to the cyclic period. Phentolamine presented a slight excitability on the electro-activity of small intestine of rats. Conclusion The NE in LHA showed the inhibitive myoelectric activity on small intestines, and this effect was introduced through a acceptor,The reacceptor in LHA may function in the inhibition of the electro-activity in small intestines.

Objective To investigate the molecular mechanism of Loureirin A mediated anti-hepatic fibrosis by evaluting its effects on proliferation , secretion ofα-smooth muscle actin (α-SMA) and transforming growth factor-beta1 (TGF-β1), and expression of rat hepatic stellate cells in vitro . Methods Primary hepatic stellate cells were isolated and cultured from Sprague-Dawley rats. After activating and inducing primary hepatic stellate cells from qHSC to aHSC, the activated hepatic stellate cells model in vitro was established. Then we observed the morphological changes of static hepatic stellate cells and activated hepatic stellate cells with inverted phase contrast microscope. Cultured hepatic stellate cells were treated with different concentrations of loureirin A and the inhibitory rate of HSCs proliferation was measured by MTT assay. The expression of Frizzled-4 was measured by western blot analysis. The content ofα-SMA and TGF-β1 in the cultured HSCs'supernatant were measured by enzyme-linked immunosorbent assay (ELISA) . Results Loureirin A the proliferation of inhibited activated hepatic stellate cells in a time-dose-dependent manner compared with the control group,IC50=0.30 μg/μL. After loureirinA treatment of the HSCs, western blot analysis showed that Frizzled-4 expression level was obviously lower than control group. Loureirin A also inhibitedα-SMA and TGFβ1 (P<0.05) secretion in the cultured HSCs'supernatant in different degree by the assay of ELISA. Conclusions The molecular mechanism of Loureirin A and Wnt signaling pathway mediated anti-hepatic fibrosis and anti-angiogenesis may involve down-regulation the expression of Frizzled-4, inhibiting the synthesis and secretion ofα-SMA,TGF-β1and the proliferation of HSCs.
