ABSTRACT
Objective To study the effect of autogeneic platelet-rich fibrin (PRF) on proliferation and adipogenic differentiation of human adipose-derived stem cells (ADSCs) in vitro.Methods ADSCs were isolated from adipose tissue obtained from donors undergoing liposuction and were cultured,and underwent identification.ADSCs at passage 3 were divided into three groups:test groups were cultured with 1PRFM and 2PRFM,and control group was cultured without PRF membrane.Then the growth of the cells was observed by inverted microscope.MTT method was used to observe cell proliferation activity at days 1,2,3,4,5,6 and 7 after culture.Adipogenic differentiation of ADSCs was observed and quantified by oil red O staining at days 3,5,7,9,11 and 14.Results Cell proliferation and adipogenic differentiation would be increased with the PRFM,There were significant differences among three groups.Conclusions PRF could significantly promote proliferation and adipogenic differentiation of ADSCs.
ABSTRACT
Objective To explore a better method to repair cervical cicatricle contracture deformity.Methods The cervicai cicatrical contraction deformity was repaird by the cervico-shoulder island skin flap with blood supply crossing and abundant anastomotic branches of the neck-shoulder blood vessels. After removing the cervical scar, the flaps were designed according to the size of the wound to be repaired, and the clinical anatomy of crossing and abundant anastomotic branches of the neck-shoulder blood vessels. The secondary wound of donor site was closed directly if the donor region was small, or closed by skin graft. Results Sixteen patients in this clinic were operated with this method, and venous return dysfunction occurred in 1 case, but blood circulation was improved after treatment. All the flaps survived with good appearance and texture. The extensive flap was created and transferred to the anterior neck by one stage without pre-expansion which met some patients'requirement of repairing cervical cicatricle contracture deformity. Conclusion The cervico-shoulder island skin flap, with abundant blood supply, is a new method to repair cervical cicatricle contracture deformity.
ABSTRACT
@# Objective To explore the effect of body-weight support treadmill training (BWSTT)on ambulatory capacity in individuals following incomplete spinal cord injury (ISCI).Methods 36 cases of incomplete SCI patients were divided randomly into control and BWSTT groups who were classified as ASIA C or D.All received comprehensive rehabilitation, and patients in BWSTT group also received BWSTT for 3 months when the physical condition was permitted.They were assessed before and after treatment.The evaluation items included measurement of ASIA lower-extremity motor assessment, functional independence measure (FIM) ambulatory function measure, 10meter ambulatory velocity and modified Barthel Index.Results The scores of ASIA lower-extremity motor assessment, FIM ambulatory function, the ambulatory 10-meter velocity in BWSTT group improved significantly when compared with the control group (P<0.05).The scores of modified Barthel Index were no difference between two groups before and after treatment (P<0.05).Conclusion BWSTT could improve ambulatory capacity for incomplete SCI patients
ABSTRACT
@#Objective To observe the effects of comprehensive rehabilitation treatment on ambulation and balance function in patients with heavy brain injury when the starting time of rehabilitation was delayed.Methods Twelve heavy brain-injured patients received comprehensive rehabilitation treatment,including ambulation and balance training.They were evaluated with Fugl-Meyer Lower Extremity Assessment Scale,Functional Independence Measure(FIM)Ambulation Function Scale,Berg Balance Scale and Modified Barthel Index(MBI).One-way ANOVA was used to assess the functional status of patients during the course of treatment.Results After 3～6 months of treatment,All the scores of the assessment items above scales in all of the patients increased significantly compared with those at first evaluation(P<0.05).Conclusion The heavy brain-injured patients can still acquire contented ambulation and balance function after accepting comprehensive rehabilitation,though the starting time of rehabilitation is delayed.
