Objective To study the protective effects of the compound with low molecular weight of anti free radical on brain ischemic and hypoxic injuries in rats.Methods The model of brain ischemic and hypoxic injuries in rats was established by unilateral carotid artery ligature just for 2 h. The compound was injected 30 minutes after the rats act on hypoxic state (10% O2+90%N2) for 1 h. Then the serum of rats was separated and the value of the superoxide dismutase (SOD) activity and malondiade (MDA) were determined, and the pathological changes were observed in brain tissue.Results Compared with rats in the model group, the compound decreased the concentrations of MDA in serum (P<0.05), and raised the level of SOD (P<0.05) significantly in therapy group. Otherwise, the pyramidal cells remained organized order, with only a few cells degenerated occasionally in rats of therapy group. Conclusion The compound has SOD like activity. It can scavenge the free radical and inhibit peroxidation of lipid, so it can prevent brain cells from the damage.

ObjectiveTo synthesize metal complex that exhibits superoxide dismutase (SOD)-like activity and determine its structure.MethodsThis chemical compound was synthesized by means of reflux in laboratory.Its structure was examined by infrared spectra (IR),nuclear magnetic resonance hydrogen spectra(H-NMR) and mass spectra (MS).The activity of the SOD was determine by xanthine oxidase (XOD).ResultsThe IR indicted that this complex showed a typical absorption band of -OH,C=N and benzene. The H-NMR reveals the existence of metal ion manganese (Mn3+ ,paramagnetic). The molecular weight was 365, which was obtained by EI-MS analysis. And this complex showed SOD-like activity.ConclusionA metal complex with low molecular weight and SOD-like activity has been synthesized.

Objective To evaluate the diagnostic value of high frequency echocardiography on mice with doxorubicin-induced cardiotoxicity and find out the most valuable monitoring indexes for early doxorubicin-induced myocardial damage.Methods Forty mice were divided into doxorubicin-injection group (ADM group) and control group randomly.Twenty mice in each group were injected with doxorubicin and saline at the same dose for 5 weeks continuously.The parameters of cardic function of ADM group and contol group were observed by high-frequency echocardiography after infection.Brain natriuretic peptide (BNP) tested by euzymelinked immunosorbent assay(ELISA) and pathological findings were used as the golden standard.Results ①The left ventricular long axis view and the apical four chamber view could be displayed clearly by transthoracic high-frequency echocardiography.②After 5 weeks intervention,weight,heart rate,left ventricular ejection fraction (LVEF),left ventricular fractional shortening (LVFS),E/A,E wave deceleration time(EDT) and other parameters showed marked difference between ADM group and control group(P ＜0.05).③The decrease of diastolic function was earlier than systolic function in ADM group.④LVEF and E/A presented good negative linear correlation to BNP(r =-0.622,P ＜0.05; r =-0.593,P ＜0.01).EDT showed positive linear correlation to BNP(r =0.501,P ＜0.05).Conclusions Cardic function of mice with doxorubicin-induced myocardial damage could be early evaluated accurately by high-frequency echocardiography,which contained good relativity with BNP.

Successful pain management of perioperative shoulder arthroscopy may allow patients to go home earlier, improve the quality of life in perioperative period, and facilitate rehabilitation. A comprehensive method to perioperative pain control has three stages including preoperative, intraoperative and postoperative phase. Successful pain reduction should begin preoperatively because of an excellent communication between patient and physician, moreover, preoperative analgesia also should be administered. Intraoperative efforts should include local wound infiltration and the administration of anesthetic medication intra-articularly. Postoperative management should include oral analgesics, constant infusion devices, Patient Controlled Analgesia (PCA), sedative-hypnotic drug, continuous cryotherapy and vicarious treatment.
