Ribs were obtained from 110 individuals undergoing thoracostomy. Bone marrow from these ribswas cultured on agar plates. The average number of cell colonies formed on the agar plates was 164?10.4/2?105 nucleated cells (33.4+-571.6/2?105 nucleated cells). Factors which might affect theculture were counting method for the mono-nucleated cells, the method of cell separation, and the use of horse serum.

This paper reviewed the Methods of evaluation and rehabilitation of mild cognitive impairment (MCI) after stroke. The Results showed that the Methods of evaluation included Mini Mental State Examination(MMSE), three Methods designed by The National Institute for Neurological Disorders and Stroke(NINDS) and The Canadian Stroke Network(CSN), and Montreal Cognitive Assessment (MoCA) and category test. The MoCA as the focus is brief, practical and effective as the major advantages. Many Methods of rehabilitation existed are still lack of evidence to support their efficacy.

Rehabilitation medicine is not the continuation and repetition, but supplement of the clinical medical treatment, and also makes up for its limitations. Medical postgraduate, mastering modern medical theory and clinical skills, should know the basic knowledge and skills of modern rehabilitation medicine well. So it is necessary to bring rehabilitation medicine course into the core curriculum of clinical medicine graduate degree.

Objective To investigate the effect of IGF-I on the apoptosis and the expression of survivin through the signaling pathway of PI-3K/Akt in colon cancer cell line SW480.Methods When colon cancer cell line SW480 was culfured,Western blot was used to detect the expression of survivin protein in SW480 cells after they were stimulated by different concentrations of IGF-I for different lengths of time.The phosphorylation of Akt in SW480 cells was determined by Western blot after SW480 cells were stimulated by 100 ng/mL IGF-I with in 2 h.Before and after the specific inhibitor LY294002 was treated in SW480 cells to block the pathway of PI-3K/Akt,the phosphorylation level of Akt protein was detected by western blot,survivin protein by western blot and cell immunofluorescence and the cell apoptosis rates of different treated-groups were measured by flow cytometry.Results IGF-I up-regulated the expression of survivin in a dose-dependent and time-dependent manner in colon cancer line SW480(when treated with IGF-I for 12h,the expression of Survivin reached the peak and when treated with 100ng/ml IGF-I,the Survivin reached the highest expression level);IGF-I actived the signaling pathway of PI-3K/Akt of SW480 cells quickly(the expression of p-Akt proteins in SW480 reached the maximum level when cultured with IGF-I for 15 and 30min,but after that they quickly decreased);IGF-I induced survivin expression through the PI-3K/Akt in colon cancer line SW480;IGF-I could inhibited the apoptosis of SW480 cells through the PI-3K/Akt[use of flow cytometry for detection in the blank,stimulation and block groups showed the SW480 cell apoptosis rate was(5.18?0.415)%,(0.85?0.052)%,(3.15?0.411)% respectirely,with significant differences between the groups(P

This study examined the effect of integrin cytoplasmic domain-associated protein 1α (ICAP-1α) and its mutatants T38A and I138A on the adhesion, migration and tube formation of 2H-11 cells. rAAV-ICAP-1α, rAAV-T38A and rAAV-I138A were constructed. After infection, the expression of ICAP-1α and p-ERK1/2, p-c-Jun protein was measured by Western blotting. Adhesion ability was evaluated by using MTT. Cell migration was determined by using Boyden chamber method. Tube formation test was conducted on Matrigel. The results showed that in ICAP-1α, T38A and I138A groups, ICAP-1α protein expression was increased. In T38A and I138A groups, phospho-ERK1/2, phospho-c-Jun protein expressions were significantly increased as compared with the control group and the GFP group. ICAP-1α group protein expression was obviously decreased when compared with the control group and the GFP group. Cell adhesion ratio was 0.1429±0.0080 in control group, 0.1434±0.0077 in GFP group and the ratio in T38A and I138A groups increased to 0.3210±0.0082 and 0.3250±0.0079, respectively. In ICAP-1α group, the ratio was decreased to 0.1005±0.0073. In T38A and I138A groups, the number of migrating 2H-11 cells was increased to 31.45±3.20 and 33.10±5.40 against 18.51±2.80 in control group and 20.47±3.12 in GFP group. In ICAP-1α group, the number was decreased to 12.06±1.72. The number of tube-like structures was increased to 20.41±2.54 in T38A and to 22.26±3.07 in I138A groups as compared to those of control group 12.45±1.84 and GFP group 13.63±2.71. In ICAP-1α group, the number of tube-like structures was decreased to 8.32±1.24. It was suggested that rAAV-T38A and rAAV-I138A transfection can substantially increase 2H-11 cell adhesion, migration and angiogenisis, while rAAV-ICAP-1α can greatly inhibit the effect. These effects might be correlated with ERK1/2 and c-Jun protein phosphorylation.

Objective To develop the quality of life questionnaire applicable to the Chinese patients with dysphagia by the translation and modification,as well as psychometric evaluation of the original swallowing quality of life questionnaire (SWAL-QOL).Methods The English version of the SWAL-QOL was translated into Chinese according to the well-accepted scale translation procedure.Then 103 patients with dysphagia were tested using the translated Chinese SWAL-QOL.The inter-rater reliability,test-retest reliability,internal consistency reliability,the content validity and construct validity were tested.Results The inter-rater reliability correlation coefficient of the SWAL-QOL was between 0.945-0.990 (P<0.01).Its test-retest coefficients ranged from 0.965 to 0.992 (P<0.01).The Cronbach coefficients ranged from 0.708 to 0.933 (P<0.01).There revealed significant correlation between each item of SWAL-QOL and its domain,with correlation coefficients between 0.723 and 0.982 (P<0.01).Factor analysis of each item of the 10 domains of SWAL-QOL extracted 10 common factors,which were with a cumulative contribution of 79.029%.Factor analysis of the total score of the 10 dimensions extracted 2 common factors including dysphagia-related quality of life and general quality of life,with a cumulative contribution of 54.718%.Conclusions The Chinese version of SWAL-QOL is reliable and valid.It can be used as an effective measuring tool to evaluate the quality of life of dysphagia patients.

Objective To explore the electrophysiological features of triggering atrial premature contraction(APC) in patients with hypertension combined paroxysmal atrial fibrillation (PAf).Metbods The originating sites and prematurity index (PI) of triggering APC were analyzed in 46 PAf patients with hypertension (hypertension group)and in 35 PAf patients without hypertension( non-hypertension group)from April,2008 to March,2011 in Shanghai Punan Hospital of Pudong New District.Results Triggering APCs in 46 cases with hypertension combined PAf in the hypertension group originated mainly in the left atrium( 81.6% ).The coupling interval (CI)of triggering APC in hypertension group was significantly shorter than that in non-triggering APC ( [ 374.1 ± 31.5 ] ms versus [ 443.6 ± 32.6 ] ms,t =23.361,P < 0.001 ) and that in triggering APC in nonhypertensive group ( [374.1 ±31.5]ms versus [395.7 ±38.2]ms,t =5.549,P <0.001 ).PI in triggering APC was lower than that in non-triggering APC in hypertension group(0.50 +0.05 versus 0.63 ±0.06,t =22.544,P < 0.001 ) and that in triggering APC in non-hypertension group (0.50 + 0.05 versus 0.55 ± 0.08,t =5.849,P < 0.001 ).Conclusion The triggering APC in patients with hypertension combined PAf mainly originates in the left atrium,the PI of triggering APC is significantly lower than that in non-hypertension patients with PAf and PAf occurs more easily in patients with hypertension.Prompt measures should be taken for hypertension patients with lower prematurity index to prevent the occurrence of PAf.
