RESUMEN

ObjectiveTo observe the effect of enriched environment (EE) combined with acupuncture at head point (HA) on behavior in rats with autism spectrum disorder. MethodsHealthy female Wistar rats were given peritoneal injection of sodium valproate at 12.5 days of gestation. Twenty-four male offspring rats were randomly selected and then randomly divided into model group (n = 6), EE group (n = 6), HA group (n = 6) and EE combined with HA group (the combined group, n = 6). Six male offspring rats born from female mice injected with the same amount of saline intraperitoneally were as control group. After four weeks of treatment, all the five groups were tested with three-chamber test and marble burying test, and the sociability index, the social novelty index and the number of buried marbles were recorded. The levels of interleukin (IL)-1β and IL-6 in peripheral blood were determined by enzyme-linked immunosorbent assay (ELISA). ResultsAfter treatment, compared with the model group, the sociability index and the social novelty index improved (P < 0.05), the number of buried marbles reduced (P < 0.05), and the levels of IL-6 and IL-1β in peripheral blood decreased in EE group, HA group and the combined group (P < 0.05); while the combined group was the best (P < 0.01). ConclusionBoth EE or acupuncture at HA could improve behavioral symptoms, and reduce the expression of inflammatory factors in rats with autism spectrum disorder. The combination of the two methods showed the best result.

RESUMEN

Objective To investigate the efficacy of acupuncture and rehabilitation therapy on lower limb motor function, and to explore a cortical mechanism using functional near infrared spectroscopy (fNIRS). Methods From December, 2020 to July, 2021, 24 stroke patients with lower limb motor dysfunction in our hospital were randomly divided into rehabilitation group (n = 12) and acupuncture-rehabilitation group (n = 12), and received routine rehabilitation training and acupuncture-rehabilitation intervention for four weeks, respectively. The control group included ten healthy subjects matched the patients. Before and after intervention, the lower limb motor function of the patients was assessed with Fugl-Meyer Assessment-Lower Extremities (FMA-LE), and all the subjects accepted fNIRS examination. The functional intensity and lateralization index (LI) of supplementary motor area (SMA), premotor cortex (PMC) and sensory motor cortex (SMC) were calculated based on oxygenated hemoglobin (HbO2). Results There was no significant difference in FMA-LE score between the rehabilitation group and the acupuncture-rehabilitation group before the intervention (P > 0.05). After four weeks of intervention, FMA-LE scores improved in both groups (t > 3.770, P 0.05). After intervention, the average functional connection increased in both groups (t > 2.178, P < 0.05), and the functional connection of the affected PMC of acupuncture-rehabilitation group increased (P < 0.05). The LI in SMC increased in the acupuncture-rehabilitation group (P < 0.05). There was a significant positive correlation between the change of functional connection of the affected PMC and the change of FMA-LE scores in the acupuncture-rehabilitation group (r = 0.579, P < 0.05). Conclusion Acupuncture with rehabilitation therapy can significantly improve the lower limb motor function and asymmetrical activation of SMC in stroke patients. The recovery of lower limb motor function may be related to the enhanced activation of affected PMC.
