Objective To investigate the effect of cognitive intervention on language function and quality of life (QOL) in elderly patients with post-stroke aphasia.Methods Fifty-five elderly patients with post-stroke aphasia were randomly divided into the control group (n =27) and the experimental group (n=28).The control group received comprehensive treatment including speech-language therapy (SLT),while the experimental group was subjected to additional cognitive intervention.All patients were enrolled in an eight-week rehabilitation program.The mini-mental state examination (MMSE) was used to assess cognitive function,a device for diagnosis and treatment of language disorders,ZM 2.1,was used to evaluate language function,and the 36-item short-form health survey (SF-36) (Chinese version) was used to assess quality of life (QOL),before and after treatment.Results After treatment,MMSE scores,language function scores in all categories and QOL scores in all dimensions improved in both groups (P＜0.05 for both).Furthermore,after treatment,there were significant differences between the two groups in MMSE scores of orientation,recall,attention and calculation,and in scores of overall language ability and the individual categories (P＜0.05 for all).Scores of the experimental group vs.the control group for the individual categories of language function were as follows:simple instructions (76.6 ± 14.1 vs.67.4± 19.3),complex instructions (66.1±12.8 vs.58.2±14.9),yes or no (72.5±12.1 vs.63.0±14.1),naming (55.0 19.5 vs.43.3±22.2),simple comprehension (67.5±21.4 vs.55.620.6),complex comprehension (44.8±17.0 vs.35.0±18.9),listening and reading words (65.4±16.7 vs.53.7±19.3),calculation (39.3±25.8 vs.25.9±19.2),memory (36.4±18.7 vs.26.3±17.8),matching (75.9±18.6 vs.65.3±17.1),simple general knowledge (68.3±18.2 vs.58.0±19.5),complex general knowledge (58.7±17.4 vs.50.0±13.3),orientation (70.7±19.6 vs.60.5±17.2) and comparison (59.9± 14.6 vs.50.2±17.5) (P＜0.05 for all).There were significant differences between the two groups in emotional function (66.7±18.2 vs.53.1±21.2),general health (67.2±12.6 vs.60.7±9.8),mental health (71.0±5.6 vs.63.1±4.2),social functioning (64.7±9.0 vs.59.3±10.2) and vitality (55.4±14.8 vs.46.9±15.6) (P＜0.05 for all).Conclusions Cognitive intervention combined with SLT can contribute to the recovery of language function and the improvement of QOL in elderly patients with post-stroke aphasia.

Objectives To investigate the process and the result of the repair of the sciatic nerve in rat by chitosan tube and polyglycolic fiber Methods The left sciatic nerves of rats were transected with 10 mm gap, then repaired with the nerve grafts in combination of NRF Walking track analysis, immunohistochemical and transmission electron microscopic examinations were carried out at different time after the operation Results Fibrous membrane and capillary could be observed on the surface of the grafts at the first week after the operation; at the 4th week, the regenerated nerve fibers grew more than half of the distances of the gap; at the 8th week, regenerated nerve fibers overcame the gap, many myelinated nerve fibers and thick myelin sheathes could be observed; at the 16th week, the grafts almost degraded and were substituted by the regenerated nerve Walking track analysis showed that sciatic nerve function recovery appeared at the 8th week, and that at the 16th week, approximately 60% of the sciatic nerve function was recovered Conclusion The nerve graft with NRF can stimulate the growth of vessels and the formation of the fibrous membrane, and is useful to the migration of Schwann cells and regeneration of axons, and degrade after the nerve regeneration

Objective To analyse the diagnosis and treatment of the single tubular type of diastematomyelia. Methods Clinical scoring and posterior tibial nerve cortical somatosensory evoked potential (PTNCSEP) were performed in 23 cases to define surgical indications and investigate the results of treatment. Results Seven cases without clinical symptoms and 11 cases without progressive neural deficit showed no significant change in terms of clinical scoring and PTNCSEP P40 latent period; while other 5 cases with progressive neural deficit improved after the surgical intervention, and operative findings confirmed that there were fibrous septum or band and other malformations. Conclusion Patients with progressive neural deficit need surgical intervention while those without progressive neural deficit and clinical symptoms only need conservative treatment and routine follow-up.
