Objective To understand the effect of diabetes on the nerve cells injury in hippocampal region by observing the nerve cells changes in this region of ischemia after focal cerebral ischemia reperfusion for rats with diabetes.Methods Sixty healthy male Wister rats were randomly divided into four groups:the control group,sham operation group,normal cerebral ischemia-reperfusion(NIR)group,and diabetic cerebral ischemia-reperfusion(DIR)group.The model of local cerebral ischemia and reperfusion was established by the thread-embolism and cerclage of rats with STZ-induced diabetes.Hematoxylin-eosin(HE)-stained neurons in hippocampal CA1 region were observed by selecting 8 un-overlapped fields under light microscope(?400);the total number of the normal pyramidal neurons with whole cellular organ structure were counted within 100 ?m length in CA1 region.The numbers of positive neurons were presented as mean with standard errors(?s).Significant differences between groups were analyzed by t-test.Results Neuronal loss or apoptotic cells were not found in the control group or sham operation group after observing under light microscope.There were neuronal losses in both NIR and DIR groups,neuronal loss of DIR group being more serious than that of NIR group(P

Objective: To explore the relationship between strain rate parameter and left ventricular diastolic function (LVDF) in patients with cardiac resynchronization therapy (CRT) by two-dimensional speckle tracking echocardiography (2D-STE).
Methods: A total of 70 heart failure (HF) patients with CRT were studied. The early left ventricular diastolic strain rate was obtained by 2D-STE technology, the differences of left ventricular diastolic functional parameters to various CRT echocardiographic responses were observed. The area of relevant parameters under ROC curve was calculated by early left ventricular diastolic strain rate for predicting CRT echocardiographic response.
Results: There were 41 patients presented as CRT echocardiographic responders at 12 months of follow-up period, 29 patients were non-responders. The most parameters of LVDF were signiifcantly improved than the base line in 41 responders. The maximum area of 2D-STE derived parameters under ROC curve was obtained by LSRE predicted CRT echocardiographic response
Conclusion: LSRE had greater value for predicting CRT echocardiographic response, it might be used as a sensitive index for evaluating LVDF in HF patients.

OBJECTIVE:To observe the clinical efficacy and safety of Kangfuxin solution combined with rhEGF solution for external use in the treatment of vitamin B12 deficiency atrophic glossitis. METHODS:Totally 94 patients with vitamin B12 deficien-cy atrophic glossitis in Xinjiang Production and Construction Corps Hospital during Jul. 2012-Jun. 2015 were divided into observa-tion group and control group according to random number table,with 47 cases in each group. Both groups received etiological treat-ment of vitamin B12 supplement. Control group was additionally given rhEGF solution for external use on tongue surface,qid. Based on control group,observation group was additionally given Kangfuxin solution and applied medical gauze saturated with liq-uid medicine to the affected area,more than 30 min each time,tid. Treatment course of 2 groups lasted for 4 week,a referral of the week. Clinical efficacies were compared between 2 groups as well as average pain indexes and lesion areas of tongue before and after treatment,and the occurrence of ADR. RESULTS:Cure rate(76.6% vs. 57.4%)and total response rate(97.9% vs. 83.0%) of observation group were significantly higher than those of control group,with statistical significance (P<0.05). Before treat-ment,there was no statistical significance in average pain indexes and lesion areas of tongue between 2 groups (P>0.05). 1-4 weeks after treatment,average pain indexes and lesion areas of tongue in 2 groups were significantly decreased,with statistical sig-nificance compared to before treatment (P<0.05). The average pain indexes of observation group were significantly lower than those of control group (3,4 weeks after treatment),and lesion areas of tongue was significantly smaller than control group (2-4 weeks after treatment),with statistical significance(P<0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:For vita-min B12 deficiency atrophic glossitis,Kangfuxin solution combined with rhEGF solution for external use can significantly improve tongue lesion and have good analgesic effect and safety.
