ABSTRACT
Objective:To investigate any effect of combining mirror visual feedback (MVF) training with robot-assisted gait training (RGT) in promoting the recovery of lower limb motor function among stroke survivors.Methods:Sixty stroke survivors were randomly divided into a combined treatment group, an RGT group and a control group, each of 20. In addition to traditional rehabilitation, the RGT group received 30min of RGT 5 days a week for 4 weeks, while the combined treatment group underwent 30min of RGT and also 20min of MVF training with the same frequency and duration. Before and after the treatment, the lower extremities motor functioning and walking ability of all of the patients were assessed using the Fugl-Meyer Assessment for the lower extremities (FMA-LE), the Berg Balance Scale (BBS) and Functional Ambulation Categories (FAC).Results:There were no systematic differences in any of the measurements before the treatment. After the 4 weeks, however, the average FMA-LE, BBS and FAC scores of the combined treatment and RGT groups were significantly better than the control group′s averages, and those of the combined treatment group were significantly superior to the RGT group′s. All of the groups had, however, improved significantly compared with before the treatment.Conclusions:Robot-assisted gait training is more effective in enhancing the motor functioning of the lower extremities and walking ability when it is combined with MVF.
ABSTRACT
Objective To explore the differences in autophagic expression levels between hypertrophic scar (HS) tissue and normal skin tissue,and further investigate the relationship between hypertrophic scar formation and autophagy protein expression through the rabbit ear hypertrophic scar model.Methods 30 patients with hypertrophic scar were collected.One hypertrophic scar tissue and one normal skin tissue were harvested.The relative expressions of LC3,P62 and Beclin-1 in each tissue specimen were detected by immunohistochemistry and Western blot.Western blot was used to detect the autophagic-associated protein LC3 (MAPLC3),P62 and Beclin-1 in the hypertrophic scar tissue of rabbit ear and the corresponding normal tissue of rabbit ears at 4 weeks,8 weeks,12 weeks,and 24 weeks,and further explore their clinical significance.Results In vivo,the expression of hypertrophic scar tissue protein LC3 and Beclin-1 was significantly stronger than that in normal skin tissue (P ＜ 0.05).The expression of P62 was significantly weaker than that in normal skin tissue (P ＜ 0.05).In animal experiments,during the process of HS formation,the protein expression of LC3 gradually increased,while the protein expression of P62 gradually decreased;the protein expression of Beclin-1 was higher than that of normal rabbit ears tissue,with statistically significant differences (P ＜ 0.05).Conclusions The expression of LC3 and Beclin-1 in human hypertrophic scar tissues is higher than that in normal tissues.While the expression of P62 is lower than that in normal tissues.That is,the expression of autophagy in human hypertrophic scar tissue showed an upward trend in a certain period of time,and was significantly higher than that in normal tissue.
ABSTRACT
The prevention and treatment of scars has always been an important task in the field of wound repair.Humans have started treatment for scars long time ago and have created a series of treatments.At the same time,with the development of science and technology,the diagnosis and treatment of scars have made great progress.Through the basic research for new therapeutic targets and innovative of treatment methods,treatment for scar turns more diversified and integrated.As a result,clinicians will suffer many challenges while having more options for scars treatment.Combined with traditional treatment,developing new treatments,and the comprehensive therapy of multiple treatment methods is the mainstream trend of scar treatment.
ABSTRACT
Post-stroke depression (PSD) is the most common psychological disorders in stroke patients. PSD not only seriously affects patients' functional recovery, quality of life and ability to return to society,but also increases the recurrence rate and mortality of stroke. In recent years,some researchers have applied non-invasive brain stimulation(NIBS) technology to treat PSD,and achieved certain curative effect. The authors reviewed current research progress of noninvasive brain stimulation for the treatment of post-stroke depression.
ABSTRACT
With the development of modern medical technology,accurate resection of tumor and timely repair and repair of defective tissues and organs are important concerns in the field of tumor research.The precise excision of tumor,refers to the preoperative assessment of systemic and local detection based on detailed to personalized surgical planning,the use of precise operation in operation,ensure as much as possible while minimizing surgical trauma to patients after removal of the lesions,creating the optimal conditions of recovery for trauma patients.Repair and regeneration of defective tissues and organs refers to the deletion or damage of tissues and organs,and gradually resume its anatomical structure and function process under the action of a variety of cells,extracellular mechanisms and related regulatory factors.Then from the tumor resection,tumor resection and accurate regeneration after three point repair technology to change rapidly in the tissue of tumor plastic organ regeneration in tissue of origin.
ABSTRACT
Objective To investigate the effect of cathodal transcranial direct current stimulation (ctDCS)on upper limb motor function in patients with stroke. Methods From July 2016 to February 2017,45 patients with first-ever stroke hemiplegia treated with rehabilitation at the Department of Rehabilitation Medicine,Xuanwu Hospital,Capital Medical University were enrolled prospectively. Their course of disease was 1 -6 months. They were randomly divided into a 1. 0 mA group,a 2. 0 mA group,and a control group (n =15 in each group)according to the random number table. The 3 groups of patients received traditional rehabilitation training,2 times a day,once for 45 min,5 days a week for 2 weeks. On this basis,the 1. 0 mA group and 2. 0 mA group were treated with 1. 0 mA and 2. 0 mA ctDCS for two weeks,once a day,once for 20 min,5 days a week at the same time,while the control group was only treated with sham stimulation. The upper limb function was evaluated before treatment and 2 weeks after treatment. Fugl-Meyer Assessment (FMA)score and Action Research Arm Test (ARAT)were used to assess the upper limb motor function. The modified Barthel index (MBI)was used to evaluate the activities of daily living. Paired t test was used to compare before and after treatment in the groups. Single factor analysis of variance was used to compare between the groups. Results (1)There were no significant differences in the upper limb FMA score, ARAT score,and MBI score before treatment among the three groups of patients (all P >0. 05). Two weeks after treatment,the upper limb FMA score,ARAT score,and MBI score of the patients in the 3 groups were significantly improved compared with those in the same groups before treatment. The differences in the 1. 0 mA group were 12 ±3,10 ±2,and 22 ±9,respectively,those in the 2. 0 mA group were 12 ±3,10 ±3, and 20 ±6,respectively,and those in the control group were 9 ±3,7 ±3,and 18 ±7,respectively in control group (all P <0. 01). (2)Two weeks after treatment,the upper limb FMA scores and ARAT scores in the 1. 0 mA group and 2. 0 mA group were superior to the control group (the FMA scores all P < 0. 01 and ARAT scores all P <0. 05),while there was no significant difference in scores between the 1. 0 mA group and 2. 0 mA group (P > 0. 05). The were no significant differences in the MBI scores among the three groups (P >0. 05). Conclusion Cathodal transcranial direct current stimulation may have a trend of improving the upper limb motor function and promote the improvement of activity of daily living in patients with stroke,however,there was no significant difference in treatment effect of ctDCS intensity between the 1. 0 mA and 2. 0 mA treatment.
