Objective: To investigate the effect of electroacupuncture (EA) on cognitive function in D-galactose (D-gal)-induced aging rats, and the correlation between the effect and nucleotide-binding oligomerization domain (NOD)-like receptor protein 3 (NLRP3)-ASC-Caspase-1 signaling pathway. Methods: Forty-six male Sprague-Dawley (SD) rats were randomly divided into a control group (n=10), a model group (n=12), an EA-7 d group (n=12) and an EA-21 d group (n=12). Except the control group, the other three groups received 42 consecutive days of intraperitoneal injection of D-gal to establish aging rat models with cognitive dysfunction. The control group received the same amount of normal saline via intraperitoneal injection. Two EA groups were given EA therapy for 21 consecutive days (began from the 22nd day of modeling) or 7 consecutive days (began from the 36th day of modeling) accordingly at Dazhui (GV 14), Baihui (GV 20), Shenshu (BL 23) and Zusanli (ST 36). After modeling/ intervention, all four groups received behavioral evaluations by Morris water maze (MWM) test, novel object recognition (NOR) test and step-down passive avoidance (SDPA) test followed by the Western blot (WB) detection of the expression levels of hippocampal NLRP3 inflammasome-associated proteins NLRP3, ASC and Caspase-1. Results: MWM (place navigation test, PNT) results showed that the escape latency in the model group was significantly longer than that in the other three groups (P<0.05), and there was no significant difference among the other three groups on the 1st day of the test (P>0.05). From the 2nd day to the 4th day of the test, there was no significant difference between the EA-21 d group and the control group (P>0.05) in the escape latency; the escape latency was significantly shorter in the EA-21 d group than in the model group and the EA-7 d group (P<0.05). MWM (spatial probe test, SPT) results showed that the time spent in the target quadrant was significantly shorter and platform crossover number was significantly lower in the model group than in the other three groups (P<0.05). The time spent in the target quadrant was longer in the EA-7 d group than in the model group (P<0.05), but was shorter than that in the control group and the EA-21 d group (P<0.05). There was no significant difference in the swimming speed among the four groups (P>0.05). NOR results showed that there was no significant difference in the recognition ratio between the EA-7 d group and the EA-21 d group (P>0.05), and the recognition ratio was significantly higher in the two EA groups than in the model group (P<0.05), but was lower than in the control group (P<0.05). SDPA results showed that the electric shock number was higher in the model group than in the other three groups (P<0.05), and the differences among the other three groups were statistically insignificant (P>0.05). The model group had the shortest step-down latency, followed by the EA-7 d group, the EA-21 d group and the control group in order (P<0.05). The WB results indicated that the expression level of NLRP3 was significantly lower in the control group and the EA-21 d group than in the model group and the EA-7 d group (P<0.05). The expression levels of ASC and Caspase-1 were significantly higher in the model group than in the other three groups (P<0.05), and there was no significant difference among these three groups (P>0.05). Conclusion: NLRP3 inflammasome may be involved in the development of cognitive decline in aging rats; 7 consecutive days of EA intervention can partially improve the cognitive impairment in aging rats though the effect is rather limited; 21 consecutive days of EA intervention may improve the learning and memory abilities in aging rats via downregulating the expression levels of NLRP3 inflammasome-associated proteins in hippocampus.

Objective:To investigate the effectiveness and safety of manual acupuncture for memory loss and sleep quality in chronic insomniacs.Methods:A total of 60 eligible participants were enrolled and randomized into either a treatment group or a control group,with 30 cases in each group.The treatment group was intervened by manual acupuncture whereas the control group was given sham acupuncture.In the two groups,the interventions were offered once every other day and three times a week,for 8 weeks in total.Before and after the treatment,Pittsburgh sleep quality index (PSQI) and eventrelated potentials (ERPs) were used to assess the patients' sleep quality and memory,respectively.Meanwhile,adverse events were monitored and recorded.Results:After 8-week treatment,both the treatment group and the control group showed a significant decrease in the PSQI global score (P＜0.001,P＜0.01),and the decrease in the treatment group was more significant than that in the control group (P＜0.001).The intra-group comparisons of ERPs indicated that,the latencies of N1 and P3 were shortened and the amplitudes of N1 and P3 were increased in the treatment group after the intervention,and the differences were statistically significant (P＜0.05,P＜0.001);in the control group,there were no significant changes in the latency and amplitude after the treatment (P＞0.05).The between-group comparisons of ERPs showed that the treatment group was more effective than the control group in shortening the latency of P3 (P＜0.01).Conclusion:Acupuncture can be a safe and effective treatment option for chronic insomnia coupled with memory impairment.

Objective: To observe the effectiveness and safety of electroacupuncture (EA) plus Luohua Anshen oral liquid for patients with perimenopausal insomnia. Methods: A total of 66 participants who met the inclusion criteria were enrolled in the randomized controlled trial and allocated to a treatment group and a control group at a ratio of 1:1, with 33 cases in each group. Both groups were given Luohua Anshen oral liquid as a basic treatment. The treatment group was additionally given EA every other day, three times a week. Both groups were treated for four weeks and a four-week follow-up was conducted. The scores of Pittsburgh sleep quality index (PSQI), Kupperman index (KI) and traditional Chinese medicine sleep syndrome scale (TCMSSS) were recorded at pre- and post-treatment, and at the follow-up. Meanwhile, adverse effects were monitored and recorded. Results: After four-week treatment, the global scores of PSQI, KI and TCMSSS in both groups declined significantly (all P<0.05), and the decreases in the treatment group were more significant than those in the control group (allP<0.05). The global scores of PSQI, KI and TCMSSS in both groups at the follow-up visit were significantly different from the corresponding baseline (allP<0.05), while insignificantly different from those assessed at post-treatment (allP>0.05). The total effective rate was 93.9％ in the treatment group, significantly higher than 72.2％ in the control group (P<0.05). No significant adverse event was reported in this trial excepted one patient experienced slight dizziness in the first acupuncture treatment. Conclusion: EA plus Luohua Anshen oral liquid is safe for perimenopausal insomnia with satisfactory short- and long-term effectiveness, and it shows certain advantage compared with using Luohua Anshen oral liquid alone.
