Objective To estimate the effect of glycoprotein (transmembrane) nonmetastatic melanoma protein B (GPNMB) on the proliferation and migration of as well as melanogenesis in melanoma cells.Methods The expression of GPNMB was detected by immunofluorescence assay in two melanoma cell lines M14 and G-361,as well as in primary human melanocytes.Then,the three kinds of cells each were classified into three groups:experimental group treated with small interfering RNA targeting GPNMB (GPNMB-siRNA),negative control group treated with the negative control siRNA,blank control group remaining untreated.Methyl thiazolyl tetrazolium (MTT) assay,transwell invasion assay and spectrophotometry were performed to evaluate cell proliferation activity,invasion potential and melanin levels,respectively.Statistical analysis was done using Student's t test.Results GPNMB was expressed in both melanoma cells and melanocytes.The transfection with GPNMB-siRNA down-regulated the mRNA and protein expressions of GPNMB in,and markedly suppressed the proliferation and migration of,melanoma cells.In detail,the proliferative activity (expressed as the absorbence value at 570 nm) of M14 and G361 cells was reduced by 35％ and 40％ respectively,the migration activity of M14 and G361 cells by 49％ and 51％ respectively,and the melanin levels in melanocytes,M14 cells and G361 cells by 73％,82％ and 69％ respectively,in the experiment group compared with those in the blank control group.Conclusions The siRNA-mediated silencing of GPNMB could effectively inhibit the proliferation of,invasion of and melanogenesis in melanoma cells,which suggests that GPNMB plays critical roles in the initiation and progression of melanoma.

Objective To explore the effect of occupational therapy (OT) on hemianesthesia and hand function after stroke. Methods 50 stroke patients with hemianesthesia were divided into OT group (n=25) and control group (n=25). The OT group accepted OT combined with routine therapy and the control group accepted routine therapy only. They were assessed with upper extremity sense of Fugl-Meyer Assessment (FMA) and evaluation of hand function before and after treatment. Results The scores of FMA and hand function improved significantly in both groups 2 months after treatment, and improved more in the OT group than in the control group (P<0.05). Conclusion OT can improve the sense and the hand function in stroke patients with hemianesthesia

Objective To explore the effect of occupational therapy (OT) on the depressive mood and activity of daily living (ADL) in patients with post stroke depression (PSD). Methods 42 patients with PSD were divided into OT group (n=21) and control group (n=21).Both 2 groups received routine therapy, and OT group received ADL training, selective recreation and sport and appreciation of music in addition.They were evaluated by modified Bathel index (MBI) and Hamilton Self-rating Scale for Depression (HAMD) before and after treatment.Results The scores of MBI increased and the scores of HAMD decreased significantly after 4 weeks in both 2 groups (P<0.001), especially in the OT group (P<0.01). Conclusion OT can improve not only ADL, but also the depressive mood in patients with PSD.

Objective To study the effect of stable expression of reconstructed human transforming growth factor-β3 ( hTGF-β3) on proliferation of precartilaginous stem cells ( PSCs) and their differentiation into cartilage chondrocytes.Methods After isolated and purified by immunological microbeads,PSCs of rats were transfected with pcDNA3.1 ( + )-hTGF-β3.MTT reduction assay ( MTT) and flow cytometry were performed to investigate the effect of transduction on proliferation and DNA synthesis.Biosynthesis of hTGF-β3 and expressions of cartilage associated genes and proteins were examined by qRT-PCR,immunohistology and Western blot.Results hTGF-β3 was expressed in PSCs stably.Compared with non-transfection group,PSCs' DNA synthesis level and proliferation rate were significantly increased after transfection.Quantitative real-time PCR and immunological investigation suggested up-regulated expression of specific genes and proteins of chondrocyte and increase of deposition of chondrocyte typical extracellular matrices proteoglycan and collagen type Ⅱ .Conclusions Gene enhanced PSCs can stably express hTGF-β3 protein to promote proliferation of PSCs and induce differentiation of PSCs in to chondrocytes,which provides a fresh approach to cartilage tissue engineering.

Objective To evaluate the radiation dose and image quality of MinDose techniques in dual-source CT coronary artery angiography.Methods 120 consecutive patients undergoing cardiac CT scans were randomly assigned into 2 groups: Group A1 with the tube current reduced to 20% of the normal tube current outside the pulsing window,and Group A2 with the tube current reduced to 4% of the normal tube current outside the pulsing window (MinDose).The image quality,noise,volume CT dose index (CTDIvol),and effective dose (E) of these two groups were evaluated.Results The mean score of imaging quality of Group A1 was (4.3 ± 0.3 ),not significantly different from that of Group A2 [(4.5 ±0.4),t=0.16,P＞0.05].The value of CTDIvol of Group A1 was (40.2 ±9.6) mGy,significantly higher than that of Group A2 [( 36.4 ± 9.1 ) mGy,t = 3.2,P ＜ 0.05].The E value of Group A1 was (9.1± 2.2) mSv ,significantly higher than that of A2 [( 8.1 ± 1.9) mSv,t = 2.7,P ＜ 0.05].Conclusion Application of the MinDose technique not only reduces the radiation dose to the patient,but also meets the requirement of diagnosis.

BACKGROUND: Myelination following axonal regeneration is a key factor affecting the recovery of spinal cord injury. Oligodendrocyte survival directly affects the myelination following axonal regeneration. OBJECTIVE: To investigate the feasibility of differentiation of rat bone marrow mesenchymal stem cells (BMSCs) into oligodendrocytes induced by neurotrophic factors. DESIGN, TIME AND SETTING: The cell molecular biology in vitro study was performed at the Laboratory of Department of Orthopaedics, Tongji Hospital from September 2006 to June 2007. MATERIALS: A total of 5 Sprague Dawley rats aged 2-4 weeks, of both gender were selected. Bilateral femur and tibia bone marrow was obtained to harvest BMSCs. METHODS: At passage 4, BMSCs were incubated in serum-free medium, supplemented with N2, 20 ng/mL basic fibroblast growth factor, 20 ng/mL epidermal growth factor for 48 hours, and incubated in medium containing 500 ng/mL insulin-like growth factor I and N2 for 3 days. MAIN OUTCOME MEASURES: Morphological changes were observed using an phase contrast microscope. Semiquantitative RT-PCR was utilized to detect specific marker mRNA expression of oligodendrocytes. Using neuron marker anti-microtubule-associated protein, astrocyte marker anti-glial fibrillary acidic protein, oligodendrocyte marker anti-galactocerebroside, anti-myelin basic protein antibody, immunocytochemical staining was performed to detect the positive rate of the differentiation of BMSCs into oligodendrocytes. RESULTS: Morphological changes in BMSCs during the differentiation into oligodendrocytes: After the induction, a majority of BMSCs presented the morphological characteristics of oligodendrocytes. Cytoplasm retraction towards nucleus, cell process extension towards outwards, and strong refraction were found. With the prolongation of time, several cell processes connected and formed a typical net-shape structure. Specific marker mRNA expression of oligodendrocytes: Following induction, specific strap of myelin basic protein mRNA and galactocerebroside mRNA could be detected. Positive rate of oligodendrocytes: During induction, the positive rates of galactocarebroside, myelin basic protein and microtubule-associated protein were 65%, 45% and 10%, respectively. CONCLUSION: The combination of epidermal growth factor, basic fibroblast growth factor and insulin-like growth factor can effectively promote the directional differentiation of BMSCs into oligodendrocytes.
