RESUMO
Objective: To investigate the effect and mechanism of brain-derived neurotrophic factor (BDNF) pretreatment for reducing myocardial ischemia/reperfusion (I/R) injury in experiment rats. Methods: Rat’s myocardial I/R model was established by left anterior descending artery ligation for 30min followed-by reperfusion for 180 min. The rats were divided into 5 groups:Sham operation group, I/R group and IR with BDNF pretreatment (1, 10, 100) nmol/(kg·ml) groups respectively. The LVSP, LVEDP, ±dp/dtmax were recorded after I/R;serum levels of LDH, CK and the cardiac tissue levels of MDA, SOD were examined;the ratios of left ventricular myocardial infarction area in different groups were observed by by Evans blue staining;cell apoptosis rates were evaluated by Tunel staining;the total-TrkB and p-TrkB in myocardium were detected by Western-blot analysis. Result: Compared with I/R group, in 3 IR with BDNF pretreatment groups, LVSP, ±dp/dtmax were gradually increasing and LVEDP were gradually decreasing, all P Conclusion: BDNF pretreatment could maintain the cardiac function in experiment rats after I/R injury, it may reduce MI area, decrease oxidative damage and apoptosis, therefore, protect myocardial cells for reducing IR injury.
RESUMO
Objective To observe the effect and nursing measures of treating diabetic peripheral nerve dis-ease with method of Fuming and washing formula of Strengthening Qi to Dredging combined with point massage.Methods 68 DPN patients who were confirmed to the diagnostic criteria were randomly divided into the observation group and the control group with 34 patients in each,they were treated by conventional treatment but additional Fuming and washing formula of Strengthening Qi to Dredging combined with point massage was used in the observation group.The course for both groups was 4 weeks.The curative effects obtained were compared after treatment.Results The total effective rate was higher in the observation group(94.1%) than that in the control group(67.6%).Conclusions Fuming and washing formula of Strengthening Qi to Dredging combined with point massage treatment on DPN has better effect than western medicine alone in promoting DPN restoration.
