ABSTRACT
@# Objective To explore the effects of transcutaneous electrical acupoint stimulation (TEAS) on upper limbs function in chronic stroke patients. Methods From March, 2016 to May, 2018, 53 patients were randomly divided into control group (n = 27) and research group (n = 26). All the patients received conventional rehabilitation, and the research group received additional intervention of TEAS, for six weeks. They were assessed with Manual Muscle Test (MMT) on upper limbs, modified Ashworth Scale (MAS), Fugl-Meyer Assessment-upper extremities (FMA-UE), Hand Motor Status Scale and modified Barthel Index (MBI) before, at the end of 6-week treatment and twelve weeks after treatment. Results There was no significant difference in all the scores between two groups at the end of 6-week treatment (t < 1.511, P > 0.05). The scores of MMT of wrist dorsal extension, FMA-UE and MBI were better in the research group than in the control group twelve weeks after end of treatment (t > 2.312, P < 0.05). Conclusion TEAS may promote the recovery of hands and upper limbs function in chronic stroke patients.
ABSTRACT
Objective To observe the effect of liraglutide, an analogue of glucagon like peptide-1 (GLP-1), on the expression of PDX-1 gene in the islet beta cells of type 2 diabetes rats. Methods Sixty male SD rats were divided into 3 groups:normal control group, diabetic model group and GLP-1 group. Normal control group was given normal diet and diabetic model group and GLP-1 group were given high fat diet. After the eighth weekend, the high fat diet group was intraperitoneally injected with streptozotocin (STZ) 30 mg/(kg·bw), and the GLP-1 group was subcutaneously injected with liraglutide 200μg/kg with 2 times per day for 8 weeks. The other groups were treated with normal saline by subcutaneous injection. Real-time fluorescent quantitative reverse transcription polymerase chain reaction (Real-Time RT-PCR) was used to detect the expression of PDX-1 gene in rat pancreatic islet cells. Results The expressions of PDX-1 mRNA in the GLP-1 group and untreated group were significantly lower (P <0.001) than that in the normal control group, but significantly higher than that after GLP-1treatment (P < 0.001). Conclusion GLP-1 can upregulate the expression of PDX-1 gene in the islet beta cells of type 2 diabetes rats.
