With the rapid development of new media,medical students' ideological and moral qualities,physical and mental health have been unprecedentedly affected.Traditional ideological and political education modes for medical students encounter great challenges.In order to strengthen the ideological and political education for medical students,we need to focus on three aspects,namely enhancing information qualities of the subjects of ideological and political education,enhancing the supervision of public opinion and guidance on new media and building new interactive environment.

AIM To investigate the protective effect of GSTT on myocardial injury induced by ischemia reperfusion. METHODS The content of lactic dehydrogenase(LDH),creatine kinase(CK),methylenedioxyamphetamine(MDA),superoxide dismutase(SOD),tumor necrosis factor alpha(TNF ?) and interleukine 6(IL 6) were determined in medium after reperfusion by simulating model of ischemia reperfusion; The content of nitric oxide(NO) was determined in medium by TNF ? injury myocardium,and mitochondrial activity was determined by MTT after TNF ? stimulated. RESULTS Compared with the model control,in the GSTT, the content of LDH,CK,MDA,TNF ? and IL 6 in medium decreased and activity of SOD increased after reperfusoin,the level of NO in medium decreased and OD 490 increased after TNF ? injuried. CONCLUSION It is suggested that GSTT can mitigate injury of ischemia reperfusion on myocardium, and has a direct protective effect on injuried myocardium.

Objective To provide the evidence for the clinical prevention and early treatment for the complication by testing microcirculation of the middle fingertip in renal failure patients with hemodialysis.Methods High-frequency ultrasounds combined with E-flow technique were applied to detect the Doppler velocitg index of middle fingertip's nail bed arteriole and ventral arteriole in 35 renal failure patients with hemodialysis.Peak systolic velocity(PSV),end-diastolic velocity(EDV)and vascular resistance index(RI)were separately measured,and comparison were made with healthy adults and renal failure patients without hemodialysis(sex and age matched).Results Compared with normal control,PSV and EDV of middle fingertip's nail bed arteriole and ventral arteriole were degraded statistically(P＜0.05),while RI was increased statistically(P＜0.05)in renal failure patients with and without hemodialysis.Compared with renal failure patients without hemodialysis,PSV and EDV were degraded(P＜0.05)and RI was increased(P＜0.05)in renal failure patients with hemodialysis.Conclusions High-frequency ultrasound combined with E-flow imaging technique can evaluate the microvascular peripheral resistance in renal failure patients with hemodialysis.
