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.

Group A,the differences among the three groups were statistically significant(P0.05). TCR,CCR,DAP,OD,BRC in Groups B and C showed trends of increasing,the differences in terms of the contents of BMP-RⅠamong the 3 phases were statistically significant(P0.05);the ER in Group B and C showed a trend of decreasing,thee difference between 4- and 8-week and 4- and 12-week were signifieantly dif- ferent(P0.05).Conclusion After application of glucocorticoid for a short term,pathological changes maintained and showed trends of inereasing in early stage.HBO can reverse these changes.The outcome of 3-course HBO therapy is better than that of 1-course therapy.

The aim of this study is to develop the Tripterygium glycosides nanoemulsion gels and investigate its pharmacodynamics. Oleic acid was used as oil phase, polyoxyethylene castor oil as surfaetant, and 1,2-propanediol as cosurfactant to screen the formula of Tripterygium glycoside nanoemulsion using the pseudo-temary phase diagrams. Then the nanoemulsion gels was prepared. The ICR mouse ears were sensitazated by 7% DNCB, and then were excited by 0.3% DNCB to stimulate the model of mouse chronic dermatitis and eczema. The concentrations of IFN-γ, IL-4 and IL-8 in mouse blood were determined by ELISA. The results showed that Tripterygium glycosides nanoemulsion gels could significantly inhibit the swelling of mouse ears(P < 0.01) and ameliorate the edama and erythema of model mouse ears skin. Also it could significantly decrease the expression of IFN-γ and IL-4 in model mouse blood. Tripterygium glycosides nanoemulsion gels had a good therapeutic effect on mouse model of dermatitis and eczema. It was expected to provide a new and long-acting exterernal preparation for the treatment of dermatitis and eczema.

This study examined the osteogenic effect of electromagnetic fields (EMF) under the simulated in vivo conditions. Rat bone marrow mesenchymal stem cells (BMSCs) and rat osteoblasts were co-cultured and exposed to 50 Hz, 1.0 mT EMF for different terms. Unexposed single-cultured BMSCs and osteoblasts were set as controls. Cell proliferation features of single-cultured BMSCs and osteoblasts were studied by using a cell counting kit (CCK-8). For the co-culture system, cells in each group were randomly chosen for alkaline phosphatase (ALP) staining on the day 7. When EMF exposure lasted for 14 days, dishes in each group were randomly chosen for total RNA extraction and von Kossa staining. The mRNA expression of osteogenic markers was detected by using real-time PCR. Our study showed that short-term EMF exposure (2 h/day) could obviously promote proliferation of BMSCs and osteoblasts, while long-term EMF (8 h/day) could promote osteogenic differentiation significantly under co-cultured conditions. Under EMF exposure, osteogenesis-related mRNA expression changed obviously in co-cultured and single-cultured cells. It was noteworthy that most osteogenic indices in osteoblasts were increased markedly after co-culture except Bmp2, which was increased gradually when cells were exposed to EMF. Compared to other indices, the expression of Bmp2 in BMSCs was increased sharply in both single-cultured and co-cultured groups when they were exposed to EMF. The mRNA expression of Bmp2 in BMSCs was approximately four times higher in 8-h EMF group than that in the unexposed group. Our results suggest that Bmp2-mediated cellular interaction induced by EMF exposure might play an important role in the osteogenic differentiation of BMSCs.

[ Objective] To explore the variation features of contrast enhanced ultrasound ( CEUS) quantitative parameters and its correlation with tumor microvessel density ( MVD ) , after the treatment of living liver cancer using high intensity focused ultrasound ( HIFU ) . [ Methods ] A group of 30 New Zealand white rabbits were made into VX2 liver cancer models, that were randomly divided into control group ( n =15, not HIFU treatment) and treatment group ( n =15, HIFU treatment).CEUS was performed, then obtaining ascending slope(AS),arrival time(AT),time-to-peak(TTP),peak intensity ( PI) ,area under curve ( AUC ) .And correlation analysis was performed with MVD obtained by immune histochemical method. [ Results ] Compared with those in the control group, AS, PI, AUC were significantly decreased in treatment group (P <0.05) and so was MVD (P <0.05).AT,TTP were significantly delayed than those in the control group (P<0.05).The AS, PI, AUC of CEUS quantitative parameters were positively correlated with MVD (P<0.05).The AT, TTP respectively showed a negative correlation with MVD ( P<0.05) . [ Conclusion] CEUS quantitative parameters of liver cancer tissue have high correlation with MVD.It can reflect the microvessel structure change of the liver cancer tissue and help to judge the curative effect and prognosis of HIFU for liver cancer.
