Results The students were able to grasp the most of the contents of the course,and reshaped their opinions on evidence-based medicine,with which,a positive impact on their medical practice was expected. Conclusion The course of evidence-based medicine for graduate students has resulted in a positive consequence.

To study the antiarrhythmic effect of the newly developed alpha/beta-blocker TJ0711, a variety of animal models of arrhythmia were induced by CaCl2, ouabain and ischemia/reperfusion. Glass microelectrode technique was used to observe action potentials of right ventricular papillary muscle of guinea pig. The onset time of arrhythmia induced by CaCl2 was significantly prolonged by TJ0711 at 0.75, 1.5 and 3 mg x kg(-1) doses. TJ0711 (1.5 and 3 mg x kg(-1)) can significantly shorten the ventricular tachycardia (VT) and ventricular fibrillation (VF) duration, the incidence of VF and mortality were significantly reduced. On ischemia-reperfusion-induced arrhythmic model, TJ0711 (0.25, 0.5, 1 and 2 mg x kg(-1)) can significantly reduce the ventricular premature contraction (PVC), VT, VF incidence, mortality, arrhythmia score with a dose-dependent manner. At the same time, rats serum lactate dehydrogenase (LDH) and creatine kinase (CK) activities decreased significantly by TJ0711 (1 and 2 mg x kg(-1)). Ouabain could cause arrhythmia in guinea pigs, when TJ0711 (0.375, 0.75, 1.5 and 3 mg x kg(-1)) was given, the doses of ouabain inducing a variety of arrhythmia PVC, VT, VF, cardiac arrest (CA) were significantly increased with a dose-dependent manner. In the TJ0711 0.1-30 micromol x L(-1) concentration range, guinea pig right ventricular papillary muscle action potential RP (rest potential), APA (action potential amplitude) and V(max) (maximum velocity of depolarization) were not significantly affected. APD20, APD50 and APD90 had a shortening trend but no statistical difference with the increase of TJ0711 concentration. TJ0711 has antiarrhythmic effect on the sympathetic nerve excitement and myocardial cell high calcium animal arrhythmia model. Myocardial action potential zero phase conduction velocity and resting membrane potential were not inhibited by TJ0711. APD20, APD50 and APD90 were shortened by TJ0711 at high concentration. Its antiarrhythmic action mechanism may be besides the action of blocking beta1 receptor, may also have a strong selective blocking action on alpha1 receptor and reducing intracellular calcium concentration.

Objective To study plasma tumor necrosis factor ?(TNF ?) level and its relationship with insulin resistance in familial type 2 DM. Methods Plasma TNF ? were determined by RIA in 32 familial type 2 DM patients, their 37 non diabetic first degree relatives and 40 healthy control subjects. Results Plasma TNF ? was significantly higher in familial type 2 DM patients[(1.19?0.21)?g/L] than in healthy control subjects[(1.00?0.18)?g/L]( P 0.05). Regression analysis indicated that TNF ? was inversely related to ISI and was a significantly independent contributor to variations in ISI. 39% of the variance in ISI was explained by TC, body mass index(BMI)and TNF ?. Conclusion The finding of an association between high plasma levels of TNF ? and insulin resistance suggests that TNF ? may be involved in the pathophysiology of insulin resistance in familial type 2 DM patients.

Objective To investigate the association of ILK expression in human renal interstitium and the pathological injury of renal interstitium in the patients with chronic nephropathy.Methods The expressions of ILK,TGF?1,E-cadherin and fibronectin(FN) in renal tissue were investigated with immunohistochemistry and computer image analysis system in 49 patients with chronic kidney disease.According to the score of the renal interstitial pathologic injury,49 patients were divided into four groups: 4 in no injury group(the normal control group),17 in slight injury group,16 in mild injury group,12 in severe injury group.Results ILK was hardly detected in normal control group,and ILK was observed in tubulointerstitial area in 3 injury groups.The expression of ILK was prominent in tubular epithelial cells,next in the damaged tubulointerstitial area.A significant positive correlation was found between the expression of ILK in renal interstitial tissue and the degree of renal tubulointerstitial pathological injury(r=0.736),as well as that of TGF?1(P

In the study we determined the content of malondialdehyde(MDA) , which is the metabolite of lipid peroxide(LPO) , in plasm and lung homogenate by thiobarbituric acid(TBA) colorimetry, and the content of phosphatidyl-choline(PC), which is the major functional composition of pulmonary surfactant (PS).and total phospholipid (TPL) by thin-layer chromatogra-phy and inorganic phosphorus quantitative analysis in rabbits with lung injury induced by oleic acid. The results showed that the MDA level wasincreased in plasm and lung homogenate; PC and TPL were decreased in lung homogenate. Administrating of 654-2 before and after (0. 5 h)lung injury could both inhibit the production LPO and prevent the decrease of PS. The findings suggest that the decrease of PS may be due to the increase of LPO and that G54-2 could modify the process.

Objective To investigate the effects of OGP (10-14) and its derivate H86A on bone metrology in rats with ovariecto-my-reduced osteoporosis. Methods Thirty-two female Sprague-Dawley rats, three months old, were randomly divided into 4 groups. Rats in groups 1 to 3 were bilaterally ovariectomized(OVX) and the others in group 4 were sham-operated. After the operation, rats in group 1 and group 2 were received derivate of OGP(10-14) H86A daily at different concentration. Group 3 were given placebo. Rats were killed after 12 weeks. Left tibias were disconnected and made into non-decalcified bone slice, and then they were detected and analyzed on indexes which were relative with bone metrology. Results Compared with Group 3, no other indexes except OV/BV was obviously different in rats with high dose H86A (P

We predicted the anti-ulcerative colitis (UC) mechanism of Fructus Amomi based on network pharmacology. The anti-UC activity of Fructus Amomi were investigated by in vivo animal experiment, and the active components of Fructus Amomi were obtained through TCMSP, PubChem database and literature research. Animal welfare and experimental procedures follow the regulations of the Animal Ethics Committee of Institute of Materia Medica of Chinese Academy of Medical Sciences. The potential targets of the active components and UC were predicted by SwissTargetPrediction, GeneCards and TTD databases. The protein-protein interaction (PPI) network was constructed by String database and Cytoscape software was used to construct a visual network of active component-disease target and perform topological analysis. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were performed using Metascape platform. The molecular docking of key components and core targets was carried out by Sybyl X software. We screened out a total of 12 active components and 189 disease-component overlapping targets. Enrichment analyses obtained 227 related GO items and 168 signaling pathways. According to the results of molecular docking, most active components of Fructus Amomi showed good affinity with the JAKs receptor family. Furthermore, Western blot results verified that Fructus Amomi could effectively inhibit JAK/STAT signaling pathway, indicating that Fructus Amomi might exert the anti-UC activity by regulating JAK/STAT signaling pathway.

ObjectiveTo observe and detect the change of invasion and migration about CNE cell line after 5-ALA Photodynamic therapy.MethodsThe relation between the inhibition rate and 5-ALA concentration & energy density of lasers was detected by MTT.Scratch wound assay and matrigel artificial basement membrane invasion assay were perforned after photodynamic therapy with different photosensitizer concentration and energy density of lasers.ResultsThe results showed that photodynamic therapy can inhibit the growth of CNE cells.The migration of CNE cell was inhibited with appropriate photosensitizer concentration and energy density of laser after photodynamic therapy.It exhibited a linear relation between cell migration and the energy density, when the photosensitizer concentration was a maximum effective concentration of 1 mmol/L (P ＜0.05). The invasion of CNE cell was also inhibited after photodynamic therapy,there is a relationship between the change of invasion and 5-ALA concentration & energy density of lasers.It which exhibited a linear relation between cell invasion and the energy density in the same photosensitizer concentration (r ＞0.8, P ＜0.0001). ConclusionThe migration and invasion of CNE cells are both inhibited after photodynamic therapy. The change of migration and invasion is related to 5-ALA concentration & energy density of laser.
