ObjectiveTo study the anatomical abnormalities of basal ganglia and research their influence on depression status in patients with post stroke depression (PSD)by diffusion tensor imaging (DTI) of MRI.MethodsPatients with basal ganglia infarction were recruited,and divided into groups of PSD and non depression control group by Hamilton Depression Rating Scale (HAMD) assessment. All the patients were evaluated with National Institute of Health Stroke Scale ( NIHSS). And the patients were checked by DTI sequence.Fractional anisotropy (FA),average diffusion coefficient (ADC) values and the number of nerve fiber were measured in bilateral caudatum,pallidum,putamen and thalamus.ResultsThe score of NIHSS (6.29 ± 3.45 ) was significantly higher in PSD group than that in non-depression group (3.95 ± 1.90 ;t =2.219,P =0.036). No significant difference was found between the two groups for the DTI data of the basal ganglia nuclei ( t =0.056-1.618,all P > 0.05 ). Compared with contralateral construction (0.40 ± 0.02 ),the FA value decreased in the left putamen ( 0.37 ± 0.03 ) in the PSD group ( t =2.243,P =0.045 ).By Spearman correlations analysis,the HAMD score was positively correlated with NIHSS score ( r =0.464,P =0.017 ),and negatively correlated with the FA values of left pallidum (r=-0.563,P=0.005),right pallidum (r=-0.416,P=0.035) and left putamen (r =-0.428,P =0.029).Conclusions The occurrence of PSD was associated with neurological functional deficit following basal ganglia infarction.The depression level was correlated with the increasing of NIHSS score,the reductions in bilateral pallidum and left putamen FA values.This research contributes to evaluation of the PSD status in patients with basal ganglia infarction.

Objective To investigate the effect of nano-silver antibacterial dressing on infection control in the patients with diabetic foot. Methods 60 patients with diabetic foot who were treated in our hospital from January 2017 to January 2018 were selected as the study subjects. They were randomly divided into intervention group and control group, with 30 cases in each group. Both groups strictly controlled blood glucose levels. After debridement, the intervention group was given nano-silver antibacterial dressing. The control group was given vaseline dressing. The degree of wound pain, the severity of wound ulcer, and the area of ulcer were evaluated at the time of enrollment and 4 weeks after treatment. The ulcer healing time and the number of dressing changes were counted in both groups. Results After intervention, the Wagner grading of the two groups was significantly improved compared with that before treatment, and the difference was statistically significant (P<0.05); after treatment, the Wagner grading in the intervention group was significantly better than that in the control group, and the difference was statistically significant (P<0.05). After intervention, the ulcer area of the two groups was significantly lower than that before the intervention (P<0.05); the ulcer area in the intervention group was smaller than that in the control group after intervention (P<0.05). The VAS in the two groups after intervention was significantly lower than that before the intervention (P<0.05); the VAS in the intervention group was significantly lower than that in the control group after intervention (P<0.05). The ulcer healing time in the intervention group was significantly shorter than that in the control group, and the difference was statistically significant (P<0.05); the number of dressing changes was significantly lower than that in the control group, and the difference was statistically significant (P<0.05). Conclusion The application of nano-silver antibacterial dressing can promote the healing of ulcers, reduce the ulcer area, improve the Wagner grading and reduce the number of dressing changes.
