Objective To study the clinical characteristics and potential influencing factors of rehabilitation of cognition in post-stroke patients with aphasia.methods Forty-one patients with aphasia after ischemic stroke,admitted to Nanfang hospital and Nanfang Yanling Hospital from June 2015 to November 2016 were included.Their primary clinical information and NIHSS scores were registered.In acute phase,Aphasia Battery of Chinese and Boston Diagnostic Aphasia Examination was used to evaluate language ability and classify the aphasia type.Non-language-based Cognitive assessment (NLCA) was used to assess patients' nonlinguistic cognition.Besides,the assessment of post-stroke depression and dependence degree of daily living activities were performed.3 months later,patients were evaluated again.A total of 30 aphasia patients completed the final follow-up.Result s(1) Compared with the baseline in patients with aphasia after stoke,all domains of language ability were significantly improved after 3 months(P<0.05).(2)Every nonlinguistic cognitive score was significantly increased within 3 months(total NLCA score(65.83±13.02 vs 48.00±25.11),memory(17.23±2.49 vs 13.30±5.42),visual spatial ability(10.67±2.43 vs 8.07±3.75),logical reasoning ability(6.53±1.48 vs 4.97±2.43),attention(25.57±5.79 vs 17.43±12.33),executive function(5.77±3.47 vs 4.20±4.23),all P<0.01).(3)The NLCA total score (62.40±14.23 vs 72.70±6.34)and scores in visual spatial (9.95±2.67 vs 12.10±0.74)and abstract reasoning(6.05±1.54 vs 7.50±0.71) of persisting aphasia patients were significantly lower than that of aphasia recovered group(all P<0.05).(4) Multivariate regression showed that initial NLCA score had a negative predictive effect on cognitive function improvement of aphasia patients 3 months after stroke(β=-0.603,P<0.01).Conclusion The rehabilitation of cognitive function in patients with aphasia after stroke is similar to that of language function.Patients with persisting aphasia may have worse performance on nonlinguistic cognition and ability of daily living,even with more serious depressive emotion.Evaluation of nonlinguistic cognition in post-stroke aphasia patients in acute phase is necessary and the score seems to be an important predicting factor of 3-month cognition.

The number of projects and the amount of sponsoring funds have been increasing during the past years.Conventional research branches are respiratory tumor and digestive tumor.Emerging research branches are lung transplantation and lung preservation.Underdeveloped research branches are acute lung injury and acute respiratory distress syndrome and thymic tumor.The position and academic impact of domestic thoracic surgery has been more valuable with the increasing number,quality and achievements of SCI papers.Therefore,international cooperation and megamergers should be encouraged and more attention should be paid to the censorship,implementation and achievements to optimize the value of projects.The aim of this article is providing important information on projects sponsored by National Nature Science Foundation of China(NSFC) in the field of general thoracic surgery,promoting the development of thoracic surgery of China.
