To investigate the effect of electroacupuncture (EA) on cognitive dysfunction in rats with hepatic encephalopathy and its underlying mechanism. Methods. Fifty Wistar rats were randomly divided into a normal group (n\u2009=\u200910) and model group (n\u2009=\u200940). Rat models of hepatic encephalopathy were established by administration of carbon tetrachloride and thioacetamide for a total of 12 weeks. At the 9th week after modeling, rats with cognitive impairment in the model group were identified by conducting the Morris water maze test, which were then randomly divided into a control group (CCl4) and treatment groups including EA group (CCl4\u2009+\u2009EA), lactulose group (CCl4\u2009+\u2009Lac), and EA plus lactulose group (CCl4\u2009+\u2009CM), with 9 rats in each group. At the end of the 9th week, rats in CCl4\u2009+\u2009Lac and CCl4\u2009+\u2009CM groups had lactulose gavage at a dose of 10\u2009mL\/kg body weight, while normal control and CCl4 groups had gavage with the same volume of normal saline once a day for 21 days until the end of the experiment. Rats in CCl4\u2009+\u2009EA and CCl4\u2009+\u2009CM groups underwent acupuncture at Baihui (GV[DU]20), Shenting (GV[DU]24), and Zusanli (ST36) acupoints, among which EA at Baihui and Shenting acupoints were given once daily for 30\u2009min lasting for 21 consecutive days. The effect of the treatment was measured by the Morris water maze test for learning and memory ability and magnetic resonance spectroscopy (MRS) for neuronal metabolism in the hippocampus of rats with hepatic encephalopathy. Pathological change in the rat hippocampus was observed by HE staining, while serum ammonia and liver function markers were detected. Western blot and real-time fluorescent quantitative PCR were used to detect the expressions of specific genes and proteins in the brain tissue. Results. Compared with those in the control group, rats undergoing EA had significantly shortened escape latency and increased number of platform crossing. H&amp;E staining confirmed that EA improved brain tissue necrosis and ameliorated nuclear pyknosis in rats with hepatic encephalopathy. Significantly decreased levels of serum ammonia, alanine aminotransferase (ALT), aspartate transaminase (AST), total bilirubin (TBil), and total bile acid (TBA) were observed in rats undergoing EA, as well as improved levels of total protein (TP) and albumin (ALB). In addition, EA inhibited the brain expressions of TNF-\u03b1, IL-1\u03b2, IL-6, iNOS, TLR4, MyD88, NF-\u03baB, p38MAPK, phosphorylated (p)-p38MAPK, STAT3, and p-STAT3 genes, as well as protein expressions of TNF-\u03b1, IL-6, TLR4, MyD88, NF-\u03baB, p38MAPK, p-p38MAPK, STAT3, and p-STAT3. MRS showed increased Glx\/Cr and decreased NAA\/Cr, Cho\/Cr and mI\/Cr in the control group, and EA significantly reversed such changes in Glx\/Cr and mI\/Cr values. Conclusion. EA ameliorated the production of excessive proinflammatory cytokines in the hippocampus of rats with cognitive dysfunction secondary to hepatic encephalopathy, which also gave rise to subsequent changes such as reduced blood ammonia level, brain-protective activated astrocytes, and lower degree of brain tissue injury. The p38MAPK\/STAT3 and TLR4\/MyD88\/NF-\u03baB signaling pathways may be involved. EA can also improve the metabolism of NAA and Cho in the rat hippocampus and thereby improve learning and memory abilities.<\/jats:p>","DOI":"10.1155\/2021\/7992688","type":"journal-article","created":{"date-parts":[[2021,10,1]],"date-time":"2021-10-01T19:11:16Z","timestamp":1633115476000},"page":"1-15","source":"Crossref","is-referenced-by-count":9,"title":["Electroacupuncture Synergistically Inhibits Proinflammatory Cytokine Production and Improves Cognitive Function in Rats with Cognitive Impairment due to Hepatic Encephalopathy through p38MAPK\/STAT3 and TLR4\/NF-\u03baB Signaling Pathways"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9650-0557","authenticated-orcid":true,"given":"Jiling","family":"Huang","sequence":"first","affiliation":[{"name":"Department of Radiology, Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine, Shanghai 201203, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhigang","family":"Gong","sequence":"additional","affiliation":[{"name":"Department of Radiology, Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine, Shanghai 201203, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yingnan","family":"Kong","sequence":"additional","affiliation":[{"name":"Department of Radiology, Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine, Shanghai 201203, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yanwen","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Radiology, Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine, Shanghai 201203, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hui","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Radiology, Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine, Shanghai 201203, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7709-6587","authenticated-orcid":true,"given":"Yingjie","family":"Kang","sequence":"additional","affiliation":[{"name":"Department of Radiology, Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine, Shanghai 201203, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7482-290X","authenticated-orcid":true,"given":"Songhua","family":"Zhan","sequence":"additional","affiliation":[{"name":"Department of Radiology, Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine, Shanghai 201203, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1515\/hsz-2021-0172"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.12688\/f1000research.11938.1"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1007\/s40265-018-1018-z"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1161\/strokeaha.109.559880"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1016\/j.jceh.2014.06.004"},{"issue":"13","key":"6","doi-asserted-by":"crossref","first-page":"6772","DOI":"10.3390\/ijms22136772","article-title":"The dual role of the GABA receptor in peripheral inflammation and neuroinflammation: a study in hyperammonemic rats","volume":"22","author":"M.
