Objective:To observe the effect of wrist-ankle acupuncture combined with electroacupuncture on neurological function and limb motor function in patients with ischemic stroke. Methods:A total of 106 eligible subjects were divided into a treatment group and a control group according to the random number table method,with 53 cases in each group.Patients in the control group were treated with conventional rehabilitation.The treatment group was treated with wrist-ankle acupuncture and electroacupuncture in addition to the treatment used in the control group.The National Institute of Heath stroke scale(NIHSS)score,Fugl-Meyer assessment scale score,Berg balance scale score,lower limb main nerve conduction velocity,and total response rate were compared between the two groups. Results:The total response rate of the treatment group was higher than that of the control group(P<0.05).After treatment,the NIHSS score,Fugl-Meyer assessment scale score,and Berg balance scale score of the two groups were improved compared with those before treatment(P<0.05),and the treatment group was significantly better than the control group(P<0.05).After treatment,only the conduction velocity of femoral nerve in the control group was better than that before treatment(P<0.05),and the conduction velocity of femoral nerve,tibial nerve,sural nerve,and common peroneal nerve in the treatment group was better than that before treatment(P<0.05),and was better than that in the control group(P<0.05). Conclusion:Wrist-ankle acupuncture and electroacupuncture combined with conventional rehabilitation therapy can significantly improve nerve and muscle function and the motor and living ability of patients with ischemic stroke,and its therapeutic effect is superior to that of conventional rehabilitation therapy alone.

OBJECTIVE:To evaluate the efficacy of exosomes derived from mesenchymal stem cells on animal models of acute liver failure. METHODS:PubMed,Web of Science,Embase,The Cochrane Library,CBM,CNKI,WanFang,and VIP databases were retrieved from inception to January 16,2023.A series of animal experiments on the treatment of acute liver failure animal models by exosomes derived from mesenchymal stem cells were collected.Two evaluators screened the literature and extracted the data independently.The bias risk was evaluated by the SYRCLE tool.The extracted data were analyzed by Revmen 5.4.1 software and Stata 17.0 software. RESULTS:A total of 241 articles were retrieved and 9 animal experiments were included,with 219 animals:110 animals in the model group and 109 animals in the exosome group.The results showed that the survival rate of animals in the exosome group improved significantly[RR=9.34,95%CI(3.91,22.29),P<0.001],the levels of serum alanine transaminase[SMD=-5.31,95%CI(-7.43,-3.19),P<0.001]and aspartate aminotransferase[SMD=-4.47,95%CI(-5.85,-3.10),P<0.001]were reduced obviously.The expressions of interleukin-1β[SMD=-11.54,95%CI(-18.12,-4.95),P=0.000 6],interleukin-6[SMD=-5.75,95%CI(-8.08,-3.41),P<0.001]and tumor necrosis factor-α[SMD=-4.46,95%CI(-6.83,-2.09),P=0.000 2],were suppressed obviously. CONCLUSION:Exosomes derived from mesenchymal stem cells effectively inhibit the inflammatory response,ameliorate liver function of animals with acute liver failure,and improve their survival rate.The results of subgroup analysis showed that the shorter survival time of animals(≤24 hours),the lower dose of transplanted exosomes(<1 mg/kg)and the source of exosomes(adipose-derived mesenchymal stem cells)may affect the efficacy of the exosomes derived from mesenchymal stem cells in the animal model of acute liver failure.This conclusion and its clinical transformation still need to be confirmed by randomized controlled studies with large sample sizes and high quality.
