Objective To investigate the status of social support and job satisfaction of community nurses and their relationship in Wuhan. Methods A total of 230 community nurses from 20 community health service centers in Wuhan were investigated by general information questionnaire, job satisfaction scale of community nurse and social support scale. Results The total score of job satisfaction was (96.14±14.76) points, the highest score of dimension was leadership and management (23.64±4.60) points, and the lowest was pay and welfare (10.83±3.00) points. The total score of social support was (37.17±7.05) points, the highest score of dimension was perceived social support (20.15 ± 4.48) points, the lowest was availability (8.05±1.57) points. There was a positive association between community nurses′social support and job satisfaction (r=0.248, P<0.05). Conclusions Social support is one of the predictors of job satisfaction. In order to make sure the sustainable development of community health services, it is necessary to know the status and take corresponding measures to improve the levels of social support and job satisfaction.

Language is an unique complex psychological activity of human beings.Language barrier is a decline of effective activities and interactions in supporting the cognitive process of language behavior.Cognitive function is affected to a certain degree in patients with post-stroke aphasia.Therefore,accurately identifying these cognitive impairments contribute to the treatment and rehabilitation of the patients with aphasia.The assessment of the severity of cognitive impairment needs to use the cognitive assessment scales.This article reviews the cognitive assessment scales that are applicable for patients with post-stroke aphasia.

Objective To research the neural substracts for the processing of the discourse-level English writing using PET-CT.Method Six healthy people underwent 18F-FDG PET examination in the pseudo-writing condition and the discourse-level English writing condition.statistical parametric mapping(SPM)was used to investigate the activicated focus in english writing thruugh pared-t test.Results The activated foci were observed in left inferior parietal lobule,left postcentral gyrus,left cingulate gyrus,left putamen,fight frontal precentral gyrus,right superior frontal gyrus,right thalamus medial dorsal nucleus,both cerebellum(P＜0.05).Conclusions The writing of English as a second language implicates conical and subcortical structures.Left inferior parietal lobule,right frontal and both cerebellum participate in the language production and processes,and left putamen is more engaged in English learning.

Objective To develop the Non-Language-Based Cognitive Assessment (NLCA) applicable to patients with aphasia and to validate the reliability and validity of NLCA.Methods Seventy-three normal subjects and 32 patients with mild cognitive impairment were evaluated by the NLCA and the Mini-Mental State Examination.Forty subjects were randomly selected from the normal subject samples were assessed with the NLCA,the Auditory Verbal Learning Test,the Rey-Osterrieth Complex Figure Test (Form A),the Stroop Color-Word Interference Test,the Raven's Standard Progressive Matrices (Part A),and the WAIS Digit Span Test.Results The NLCA had high inter-rater agreement (Cronbach's α coefficient 0.836),reliability among the assessors 0.895-0.953,test-retest reliability 0.863-0.952 at at a 2-6 week interval.The years of education was significantly correlated with NLCA (r =0.852,r ＜ 0.01).When the Montreal Cognitive Assessment was used as diagnostic criteria,the area under the receiver operating characteristic curve was 0.899 (95％ confidence interval 0.827-0.972).When cutoff at 70,the NLCA had had high sensitivity,specificity,positive predictive value and negative predictive value in the identification of patients with mild cognitive impairment.Conclusions The NLCA has good reliability and validity.It is an effective cognitive function assessment that meets the basic requirements of the neuropsychological tests.

ObjectiveTo investigate the clinical features of Chinese dysgraphia and then probe into its mechanisms in a patient with semantic dementia(SD).MethodsThe patient with SD finished the writing part of the Aphasia Battery of Chinese (Aphasia Battery of Chinese,ABC) and the Chinese agraphia battery (Chinese agraphia battery,CAB ) in addition to a series of other neuropsychological tests.Results( 1 ) On the Wechsler Adult intelligence scale,the patient performed poorly on information and vocabulary with scores of 6/29 and 8/80,respectively.He spoke out only 11 names totally on the category fluency test within 1 minute,while 25 names or more than were normal.Semantic features test showed he made 37 right answers of 60 questions,with scores of 8/20 on category,7/20 on function and 8/20 on nature features.(2)The writing disorder exhibited Chinese aphasia agraphia with obvious difficulty in forming characters,wrong characters of the same pronunciation or the same form or unrelated errors,and grammatical impairments.Its damage from serious to light occurred in picture writing( 6/40),writing sentences to convey meaning(1/10),dictation(11/40) and automatic writing(35/40).The transcription was relatively preserved (40/40 ). (3)He scored 20 and 19 points on MMSE and MoCA.Executive function was damaged significantly,while recent memory was preserved relatively.ConclusionThe patient with SD shows an impoverished store of general knowledge and poor comprehension of single-word.The nature of SD's dysgraphia presents Chinese aphasia agraphia,undoubtedly due to progressive deterioration in semantic memory.More importantly,its error types and distribution show apparent discrepancy from that of alphabetic script.Presumably because Chinese writing system is logographic in nature and the pathway of comprehension concerning syllable-orthography-morphemes mapping,while alphabetic writing system follows a principle of mapping graphemes on-to phonemes and letters themselves dont stand for any meaning.

Objective To investigate the effectiveness of donepezil in the treatment of early post-stroke aphasia (PSA).Methods PSA patients within one month after onset were randomly assigned into either a donepezil group or a control group.On the basis of conventional medication,the donepezil group was given hydrochloride donepezil 5 mg/d.The patients were followed-up after 4 week.The efficacy was evaluated by the Aphasia Battery of Chinese (ABC),the National Institute of Health Stroke Scale (NIHSS),the Stroke Aphasic Depression Questionnaire (SADQ),Chinese version,and the Treatment Emergent Symptom Scale (TESS) before and after treatment.Results A total of 48 PSA patients were enrolled in the study.Both the donepezil group and the control group had 24 patients and they all completed the study.There were no significant differences in age,years of education,NIHSS score,SADQ score,stroke duration,as well as the proportions of male,hypertension,diabetes,hyperlipidemia,heart disease,previous stroke or history of transient ischemic attack,smoking alcohol consumption,type of stroke,and lesion site (all P ＜ 0.01).There were significant differences in each language score before and after treatment both in the donepezil group and in the control group (all P ＜0.01).The difference values of listening comprehension (47.8 ± 24.7 vs.22.0 ± 15.4; t =4.342,P =0.000)and reading comprehension (20.5 ± 14.0 vs.8.1 ± 10.5; t =3.483,P ＜0.01) scores before and after treatment in the donepezil group were significantly higher than those in the control group,while there were no significant differences in the information quantity of speech,fluency,series language,repetition,naming,and reading scores (all P ＞0.05).As compared with the control group,there were significant differences in the difference values of the SADQ scores before and after treatment in the donepezil group (6.2 ±6.0 vs.2.5 ±3.0; t =2.717,P=0.009).No serious adverse reactions were observed in both groups.Conclusions On the basis of conventional stroke treatment,using hydrochloride donepezil in the early PSA patients has promotion effect on the improvement of listening comprehension and reading comprehension of language function.

Objective To observe activated cerebral areas during the task of writing in second language by early and late acquisition bilinguals and explore the neuropsychological mechanism. Methods Twelve subjects were divided into group of early acquisition high proficiency bilinguals(EAHP) and group of late acquisition high proficiency bilinguals(LAHP). Each subject carried out the task of pseudo-writing and English writing. After functional imaging,statistical parametric mapping was used to compare data of the two tasks through paired- t test in both two groups. A conjunction analysis was conducted between the two groups also. Areas where the metabolism of glucose changed were analyzed. Then, the corresponding images about activated cerebral regions were obtained.Results Cerebral areas where the metabolism of glucose increased in EAHP: bilateral middle frontal gyrus( Z=4.35/2. 01 ), bilateral cerebellum ( Z = 2.97/2.53 ) and left head of caudate nucleus ( Z = 3.07 ), etc. Cerebral areas where the metabolism of glucose increased in LAHP: right superior frontal gyrus(Z=4.06), right cerebellum( Z=4.63), left putamen(Z=2.70) ,etc. Cerebral areas where the metabolism of glucose increased in compared data of LAHP with data of EAHP: right frontal gyrus ( Z = 2.92 ), right temporal lobe( Z = 2.31 ), etc. Conclusion Extensive cerebral cortex and subcortical structures participate the process of writing in the second language. Age of bilingual acquisition is one of the factors affecting cerebral localization of writing in second language.

Ubiquitin-proteasome pathway is one of the primary pathway in intracellular protein degrada-tion,therefore the ubiquitin conjugating enzyme D3(UbE2D3)which involved in the ubiquitin mineralization process can affect the biological effects accordingly to affect some protein and nucleic acid content and activity. The function that participate in modification and degradation of some cancer factors is vital in tumor cells,and followed by tumor biological behavior changing. Researches show that UbE2D3 correlates with human telomer-ase reverse transcriptase( hTERT),radiation sensitivity,aggressive,etc in breast cancer.

Objective To induce adipose-derived mesenchymal stem cells (ADMSCs) differentiation into cardiomyocytes, so as to provide stem cells for myocardial regeneration.Method ADMSCs were isolated and cultured from adult adipose tissue in vitro.They were induced with 10μmol/L 5-azacytidine (5Aza) for 24h.At the 7th, 14th, 21st days after induction, the expression of α-sarcomeric actin, and myosin heavy chain were repeatedly detected by immunocytochemistry.The expression of ANP was detected by RT-PCR.Results At the 7th day after induction, there was no expression of α-sarcomeric actin and MHC.At the 14th day, there was a little expression of α-sarcomeric actin and MHC that could be seen in cells.At the 21st day, there was increased expression of α-sarcomeric and MHC, and the expression of ANP was positive results detected by RT-PCR.Conclusions 5-Aza can induced ADMSCs to differentiate into cardiomyocytes.ADMSCs might be a potential source of cell transplantation for myocardial.

Objective To evaluate the capability of virtual non-contrast (VNC)of the second-generation dual-source CT (DSCT), and to display the adipose tissue of gastric serosa.Methods 48 patients with gastric cancer undergoing preoperative DSCT and sur-gery were enrolled.The true non-contrast (TNC)values and VNC values of perigastric adipose tissue were measured and compared with conventional non-contrast scanning and VNC of arterial phase and venous phase.The VNC values of perigastric adipose tissue were compared between serosal involvement group and non-serosal involvement group.Results There was statistical difference be-tween TNC values and VNC values of perigastric adipose tissue (P <0.05),the absolute differences were under 13 HU.The differ-ence of VNC values between serosal involvement group and non-serosal involvement group was significant (P <0.05).Conclusion VNC of the second-generation DSCT can clearly display the adipose tissue of gastric serosa.It has certain capability in judging sero-sal involvement.VNC has the proficiency to replace conventional non-contrast scanning.
