Spatial memory is crucial for survival within external surroundings and wild *** hippocampus,a critical hub for spatial learning and memory formation,has received extensive investigations on how neuromodulators shape its functions(Teixeira et al.,2018;Zhang et al.,2024).However,the landscape of neuromodulations in the hippocampal system remains poorly understood because most studies focus on classical monoamine neuromodulators,such as acetylcholine,serotonin,dopamine,and *** neuropeptides,comprising the most abundant neuromodulators in the central nervous system,play a pivotal role in neural information processing in the hippocampal ***(CCK),one of the most abundant neuropeptides,has been implicated in regulating various physiological and neurobiological statuses(Chen et al.,2019).CCK-A receptor(CCK-AR)and CCK-B receptors(CCK-BR)are two key receptors mediating the biological functions of CCK,both of which belong to class-A sevenfold transmembrane G protein-coupled receptors(Nishimura et al.,2015).CCK-AR preferentially reacts to sulfated CCK,whereas CCK-BR binds both CCK and gastrin with similar affinities(Ding et al.,2022).The expression patterns of CCK-AR and CCK-BR are distinct,implying that CCK has various functions in target *** instance,CCK-AR is widely expressed in the GI and brain subregions and is hence implicated in the control of digestive function and satiety ***,CCK-BR is abundantly and widely distributed in the central nervous system,which majorly regulates anxiety,learning,and memory(Ding et al.,2022).However,the roles of endogenous CCK and CCK receptors in regulating hippocampal function at electrophysiological and behavioral levels have received less attention.

OBJECTIVE: To examine the effect of electroacupuncture(EA) application on postoperative pain levels and the amount of analgesic use in patients who underwent periodontal flap surgery. METHODS: In this prospective, randomized and controlled study, patients planned for periodontal surgery were divided into two groups [EA group(n = 22): patients who received electroacupuncture and control group(n = 22): patients who did not receive electroacupuncture]. Electroacupuncture was applied bilaterally to the Hegu(LI4), Daying(ST5), and Jiache(ST5) points of the patients in the EA group immediately before and after the flap surgery for 30 min at a frequency of 50 Hz to each point at a current that the patient could tolerate. The patients in the control group underwent flap surgery without applying electroacupuncture. Patients were asked to record their pain levels on the visual analog scale and the number of analgesic tablets they took during the 7 postoperative days on the given form. RESULTS: The total mean score of pain felt in the EA group(16.60 ± 2.78) was found to be significantly lower than that in the control group(31.37 ± 2.78)(P = 0.001). No significant difference was found between the groups regarding the amount of analgesics taken(4.77 ± 4.72, 5.82 ± 3.11)(P = 0.111). CONCLUSIONS: Our study shows that electroacupuncture application is beneficial in reducing pain after periodontal flap surgery. Overall, more research is needed to fully understand the effects of electroacupuncture on postoperative pain.
