Front Neurosci 2023; 17:1211044. [PMID: 37397457 PMCID: PMC10309044 DOI: 10.3389/fnins.2023.1211044] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2023] [Accepted: 05/30/2023] [Indexed: 07/04/2023] Open
Abstract
Stroke is one of the important causes of both disability and death worldwide, which is very common in older adults. Post-stroke cognitive impairment (PSCI) is a common secondary damage of stroke, which is the main cause of long-term disability and decreased quality of life in stroke patients, which brings a heavy burden to society and families. Acupuncture, as one of the oldest and widely used worldwide techniques in Chinese medicine, is recommended by the World Health Organization (WHO) as an alternative and complementary strategy for improving stroke care. This review comprehensively summarizes literature from the last 25 years, showing that acupuncture can exert strong beneficial effect on PSCI. The mechanisms of acupuncture on PSCI involves anti-neuronal apoptosis, promoting synaptic plasticity, alleviating central and peripheral inflammatory reactions, and regulating brain energy metabolism disorders (including improving cerebral blood flow, glucose utilization and mitochondrial structure and function, etc.), etc. The effects and mechanisms of acupuncture on PSCI reviewed in this study provides scientific and reliable evidence for acupuncture application for PSCI.

Chin Med 2023; 18:8.

Abstract
Cognitive impairment is a prevalent neurological disorder that burdens families and the healthcare system. Current conventional therapies for cognitive impairment, such as cholinesterase inhibitors and N-methyl-d-aspartate receptor antagonists, are unable to completely stop or reverse the progression of the disease. Also, these medicines may cause serious problems with the digestive system, cardiovascular system, and sleep. Clinically, stimulation of acupoints has the potential to ameliorate the common symptoms of a variety of cognitive disorders, such as memory deficit, language dysfunction, executive dysfunction, reduced ability to live independently, etc. There are common acupoint stimulation mechanisms for treating various types of cognitive impairment, but few systematic analyses of the underlying mechanisms in this domain have been performed. This study comprehensively reviewed the basic research from the last 20 years and found that acupoint stimulation can effectively improve the spatial learning and memory of animals. The common mechanism may be that acupoint stimulation protects hippocampal neurons by preventing apoptosis and scavenging toxic proteins. Additionally, acupoint stimulation has antioxidant and anti-inflammatory effects, promoting neural regeneration, regulating synaptic plasticity, and normalizing neural circuits by restoring brain functional activity and connectivity. Acupoint stimulation also inhibits the production of amyloid β-peptide and the phosphorylation of Tau protein, suggesting that it may protect neurons by promoting correct protein folding and regulating the degradation of toxic proteins via the autophagy-lysosomal pathway. However, the benefits of acupoint stimulation still need to be further explored in more high-quality studies in the future.

Feasibility of electroacupuncture at Baihui (GV20) and Zusanli (ST36) on survival with a favorable neurological outcome in patients with postcardiac arrest syndrome after in-hospital cardiac arrest: study protocol for a pilot randomized controlled trial. Pilot Feasibility Stud 2023; 9:8.

Abstract
BACKGROUND At present, even the first-line medication epinephrine still shows no evidence of a favourable neurological outcome in patients with sudden cardiac arrest (SCA). The high mortality of patients with postcardiac arrest syndrome (PCAS) can be attributed to brain injury, myocardial dysfunction, systemic ischaemia/reperfusion response, and persistent precipitating pathology. Targeted temperature management, the only clinically proven method in the treatment of PCAS, is still associated with a series of problems that have not been completely resolved. Acupuncture is a crucial therapy in traditional Chinese medicine. On the basis of the results of previous studies, we hypothesize that electroacupuncture (EA) might provide therapeutic benefits in the treatment of PCAS. This study will explore the feasibility of EA on SCA patients. METHODS This is a prospective pilot, randomized controlled clinical trial. Eligible patients with PCAS after in-hospital cardiac arrest (IHCA) admitted to our department will be randomly allocated to the control group or the EA group. Both groups will receive standard therapy according to American Heart Association guidelines for cardiopulmonary resuscitation. However, the EA group will also receive acupuncture at the Baihui acupoint (GV20) and Zusanli acupoint (ST36) with EA stimulation for 30 min using a dense-dispersed wave at frequencies of 20 and 100 Hz, a current intensity of less than 10 mA, and a pulse width of 0.5 ms. EA treatment will be administered for up to 14 days (until either discharge or death). The primary endpoint is survival with a favourable neurological outcome. The secondary endpoints are neurological scores, cardiac function parameters, and other clinical parameters, including Sequential Organ Failure Assessment (SOFA) scores and Acute Physiology and Chronic Health Evaluation (APACHE) II scores, on days 0 to 28. DISCUSSION This study will provide crucial clinical evidence on the efficacy of EA in PCAS when used as an adjunctive treatment with AHA standard therapy.

JOURNAL OF INTEGRATIVE MEDICINE 2023; 21:89-98. [PMID: 36424268 DOI: 10.1016/j.joim.2022.11.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/07/2021] [Accepted: 09/06/2022] [Indexed: 11/11/2022]
Abstract
OBJECTIVE The study explores the effects of electroacupuncture (EA) at the governing vessel (GV) on proteomic changes in the hippocampus of rats with cognitive impairment. METHODS Healthy male rats were randomly divided into 3 groups: sham, model and EA. Cognitive impairment was induced by left middle cerebral artery occlusion in the model and EA groups. Rats in the EA group were treated with EA at Shenting (GV24) and Baihui (GV20) for 7 d. Neurological deficit was scored using the Longa scale, the learning and memory ability was detected using the Morris water maze (MWM) test, and the proteomic profiling in the hippocampus was analyzed using protein-labeling technology based on the isobaric tag for relative and absolute quantitation (iTRAQ). The Western blot (WB) analysis was used to detect the proteins and validate the results of iTRAQ. RESULTS Compared with the model group, the neurological deficit score was significantly reduced, and the escape latency in the MWM test was significantly shortened, while the number of platform crossings increased in the EA group. A total of 2872 proteins were identified by iTRAQ. Differentially expressed proteins (DEPs) were identified between different groups: 92 proteins were upregulated and 103 were downregulated in the model group compared with the sham group, while 142 proteins were upregulated and 126 were downregulated in the EA group compared with the model group. Most of the DEPs were involved in oxidative phosphorylation, glycolipid metabolism and synaptic transmission. Furthermore, we also verified 4 DEPs using WB technology. Although the WB results were not exactly the same as the iTRAQ results, the expression trends of the DEPs were consistent. The upregulation of heat-shock protein β1 (Hspb1) was the highest in the EA group compared to the model group. CONCLUSION EA can effect proteomic changes in the hippocampus of rats with cognitive impairment. Hspb1 may be involved in the molecular mechanism by which acupuncture improves cognitive impairment.

Front Neurol 2022; 13:855362.

Abstract
Cerebral ischemic stroke is a huge threat to the health and life of many people. Electroacupuncture (EA) at Baihui (GV20) and Shenting (GV24) acupoints can notably alleviate cerebral ischemia/reperfusion injury (CIRI). However, the molecular basis underlying the effectiveness of EA at the GV20 and GV24 acupoints for CIRI remains largely unknown. Our present study demonstrated that EA treatment at the GV20 and GV24 acupoints markedly alleviated middle cerebral artery occlusion/reperfusion (MCAO/R)-induced cognitive deficits and cerebral infarction in rats. Proteomics analysis revealed that 195 and 218 proteins were dysregulated in rat hippocampal tissues in the MCAO/R vs. sham group and thhhe EA vs. MCAO/R group, respectively. Moreover, 62 proteins with converse alteration trends in MCAO/R vs. sham and EA vs. MCAO/R groups were identified. These proteins might be implicated in the EA-mediated protective effect against MCAO/R-induced cerebral injury. GO enrichment analysis showed that 39 dysregulated proteins in the MCAO/R vs. sham group and 40 dysregulated proteins in the EA vs. MCAO/R group were related to brain and nerve development. Protein–protein interaction analysis of the abovementioned dysregulated proteins associated with brain and nerve development suggested that Pten/Akt pathway-related proteins might play major roles in regulating EA-mediated protective effects against MCAO/R-induced brain and nerve injury. Western blot assays demonstrated that Pak4, Akt3, and Efnb2 were expressed at low levels in the MCAO/R group vs. the sham group but at high levels in the EA group vs. the MCAO/R group. In conclusion, multiple proteins related to the protective effect of EA at the GV20 and GV24 acupoints against CIRI were identified in our study.

Abstract
Surgical pain is associated with delirium in patients, and acupuncture can treat pain. However, whether electroacupuncture can attenuate the surgical pain-associated delirium via the gut-brain axis remains unknown. Leveraging a mouse model of foot incision-induced surgical pain and delirium-like behavior, we found that electroacupuncture stimulation at specific acupoints (e.g., DU20+KI1) attenuated both surgical pain and delirium-like behavior in mice. Mechanistically, mice with incision-induced surgical pain and delirium-like behavior showed gut microbiota imbalance, microglia activation in the spinal cord, somatosensory cortex, and hippocampus, as well as an enhanced dendritic spine elimination in cortex revealed by two-photon imaging. The electroacupuncture regimen that alleviated surgical pain and delirium-like behavior in mice also effectively restored the gut microbiota balance, prevented the microglia activation, and reversed the dendritic spine elimination. These data demonstrated a potentially important gut-brain interactive mechanism underlying the surgical pain-induced delirium in mice. Pending further studies, these findings revealed a possible therapeutic approach in preventing and/or treating postoperative delirium by using perioperative electroacupuncture stimulation in patients.

Abstract
OBJECTIVE To systematically research the impact of warming needle moxibustion (WNM) for Alzheimer's Disease (AD). METHODS Four Chinese databases and six English databases were systematically searched. Randomized controlled trials (RCTs) involving the use of WNM to intervene in AD patients were included. Data were extracted from the included studies and methodological quality was evaluated according to the Cochrane Handbook for Systematic Reviews of Intervention 5.1.0. Meta-analysis was performed using RevMan 5.4 software. RESULTS 8 RCTs comprising 524 patients were included. Most studies had no significant bias. The study showed that WNM was more effective in the treatment of AD than acupuncture or pharmacotherapy. The findings were as follows: MMSE (MD = 1.01, 95%CI: 0.13, 1.90, P = 0.03) and CDR (MD = -0.73, 95%CI: -0.84, -0.61, P < 0.00001) for global cognitive function, ADL (MD = -1.84, 95%CI: -2.47, -1.22, P < 0.00001) for activities of daily living, Syndrome Differentiation Scale of Dementia (SDSD) (MD = -2.67, 95%CI: -3.62, -1.72, P < 0.00001), and the total effective rate of patients (OR = 3.20, 95%CI: 1.90 to 5.38, P < 0.0001). The differences in all indicators were statistically significant. CONCLUSION WNM might have a significant effect on improving cognitive function and daily living ability, reducing the symptoms of AD, and increase the total effective rate. WNM is an effective non-pharmacological therapy for patients with AD.

Abstract
Interleukin 10 (IL-10) is a synthetic inhibitor of human cytokines with immunomodulatory and anti-inflammatory effects. This study was designed to investigate the expression variation of IL-10 in the multiple sites including cortex, hippocampus, and lung tissues of neonatal hypoxic-ischemic (HI) rats and explore the crucial role of IL-10 in alleviating HI brain damage. In this study, neonatal Sprague-Dawley rats were subjected to the right common carotid artery ligation, followed by 2 h of hypoxia. The expression of IL-10 in the cortex, hippocampus, and lung tissues was measured with immunohistochemistry, real-time quantitative polymerase chain reaction (RT-qPCR), and western blot (WB). Immunofluorescence double staining was performed to observe the localization of IL-10 in neurons and astrocytes. Moreover, not-targeting and targeting IL-10 siRNA lentivirus vectors were injected into the rats of the negative control (NC) and IL-10 group, respectively, and the mRNA levels of B-cell lymphoma 2 (Bcl-2) and endoplasmic reticulum protein 29 (ERp29) were detected by RT-qPCR following IL-10 silence. The results demonstrated that the IL-10 expression was markedly increased after HI and IL-10 were colocalized with neurons and astrocytes which were badly injured by HI insult. In addition, Bcl-2 and ERp29 were remarkably decreased following IL-10 mRNA interference compared with the NC group. Our findings revealed that IL-10 exerted its antiapoptotic and neuroprotective effects by regulating the expression of Bcl-2 and ERp29, indicating that IL-10 may be a promising molecule target for HIE treatment.

Abstract
Background Cerebral ischemia-reperfusion (I/R) injury, the most common form of stroke, has high mortality and often brings persistent and serious brain dysfunction among survivors. Administration of adipose-derived mesenchymal stem cells (ASCs) has been suggested to alleviate the I/R brain injury, but the mechanism remains uncharacterized. Here, we aimed at investigating the mechanism of ASCs and their extracellular vesicles (EVs) in the repair of or protection from I/R injury. Methods We established the middle cerebral artery occlusion (MCAO) model and oxygen-glucose deprivation/reperfusion (OGD/RP) neuron model. ASCs or ASC-derived EVs (ASC-EVs) were co-cultured with neurons. RT-qPCR and Western blot analyses determined microRNA (miRNA)-22-3p, BMP2, BMF, and KDM6B expression in neurons upon treatment with ASC-EVs. Bioinformatics analysis predicted the binding between miR-22-3p and KDM6B. Using gain- and loss-of-function methods, we tested the impact of these molecules on I/R injury in vivo and in vitro. Results Treatment with ASCs and ASC-derived EVs significantly alleviated the I/R brain injury in vivo, elevated neuron viability in vitro, and decreased apoptosis. Interestingly, miR-22-3p was upregulated in ASC-EVs, and treatment with EV-miR-22-3p inhibitor led to increased apoptosis and decreased neuronal. Of note, miR-22-3p bound to and inhibited KDM6B, as demonstrated by dual-luciferase reporter gene assay and Western blot assay. Overexpression of KDM6B enhanced apoptosis of neurons in the OGD/RP model, and KDM6B bound to BMB2 and promoted its expression by binding to BMP2. Silencing of BMF reduced infarct volume and apoptosis in the stroke model. Conclusion Results support a conclusion that ASC-EV-derived miR-22-3p could alleviate brain ischemic injury by inhibiting KDM6B-mediated effects on the BMP2/BMF axis. These findings compelling indicate a novel treatment strategy for cerebral ischemic injury.

Abstract
Acute focal cerebral ischemic stroke (IS) is a leading cause of morbidity and mortality worldwide. Acupuncture is an emerging alternative therapy that has been beneficial to acute brain ischemia. However, the underlying protective mechanism of its neuroprotective effect remains unclear. Human original circadian rhythm will be lost after IS, which seriously affects the quality of life and functional recovery of stroke patients. We hypothesize that acupuncture treats IS by regulating the balance of Clock and Bmal1. This study aims to explore the effect of acupuncture at acupoints GV20 and BL23 on neuroprotection and anti-apoptosis in middle cerebral artery occlusion (MCAO) rats and expression of apoptosis and circadian rhythm related proteins. Male Sprague-Dawley (SD) rats were randomly divided into five groups: normal group (Normal), sham model group (Sham MCAO), MCAO model group (MCAO), sham electroacupuncture group (Sham EA) and electroacupuncture group (EA). The MCAO model was prepared by electrocoagulation. The first acupuncture treatment was performed within 2 h after surgery, and then acupuncture therapy was performed on 1st day, 2nd day and 3rd day respectively. After their neurological examination at 72 h of ischemia, the rats from each group were sacrificed. Triphenyltetrazolium chloride (TTC) staining was used to evaluate the brain infarct size. Ultrastructural observation on cerebral ischemic cortex and serum inflammatory cytokines were evaluated. TUNEL staining was used to detect cell apoptosis of brain tissue. The expression levels of proteins Bax, bcl-2, caspase-3, Clock and Bmal1 in the cerebral ischemic region were detected by immunofluorescence staining. Here, we presented evidence that EA at GV20 and BL23 could significantly improve the neurological deficit score and infarct size, and alleviate the cell apoptosis of brain tissue. Moreover, acupuncture treatment upregulated the anti-apoptotic Bcl-2/Bax ratio and reversed the upregulation of caspase-3 following 72-h cerebral ischemia. In addition, the expression levels of circadian proteins Clock and Bmal1 were upregulated in EA group while compared with MCAO group. Our study demonstrated that acupuncture exerted neuroprotective effect against neuronal apoptosis after stroke and the mechanism might be related with regulation of circadian rhythm proteins Clock and Bmal1.

Inhibition of esophageal-carcinoma cell proliferation by genistein via suppression of JAK1/2-STAT3 and AKT/MDM2/p53 signaling pathways. Aging (Albany NY) 2020; 12:6240-6259.

Abstract
Esophageal carcinoma (EsC) is a clinically challenging neoplastic disease. Genistein, a natural isoflavone product, has anti-tumor properties. Through in vitro and in vivo studies, we found that genistein suppressed EsC cell proliferation in a time- and concentration-dependent manner. In addition, genistein markedly promoted apoptosis and arrested cell cycle at the G0/G1 phase in a concentration-dependent manner. Furthermore, high concentrations of genistein have no adverse effect on normal esophageal epithelial cells. Mechanistically, genistein treatment strikingly reduced the expression of cell cycle-associated genes, and up-regulated the expression of cell apoptosis-related genes in EsC cells. Additionally, genistein dramatically decreased epidermal growth factor receptor (EGFR) expression and attenuated its down-stream signaling molecules STAT3, MDM2, Akt and JAK1/2 phosphorylation, resulting in inhibited nuclear translocation of STAT3 and MDM2, thereby inhibiting the JAK1/2-STAT3 and AKT/MDM2/p53 signaling pathways. In xenograft nude mice, genistein administration strikingly impaired tumor growth in a dose-dependent manner. Moreover, similar disturbances in molecular mechanisms were observed in vivo. Taken together, genistein suppressed the JAK1/2-STAT3 and AKT/MDM2/p53 signaling pathways by decreasing EGFR expression, leading to cell apoptosis, cell cycle arrest, and proliferation inhibition in EsC cells. Our findings suggest that genistein may be a promising alternative adjuvant therapy for patients with EsC.

Abstract
In this article, we review how acupuncture regulates oxidative stress to prevent ischemia–reperfusion injury. We electronically searched databases, including PubMed, Clinical Key and the Cochrane Library, from their inception to November 2019 by using the following medical subject headings and keywords: acupuncture, ischemia-reperfusion injury, oxidative stress, reactive oxygen species, and antioxidants. We concluded that acupuncture is effective in treating oxidation after ischemia-reperfusion injury. In addition to increasing the activity of antioxidant enzymes and downregulating the generation of reactive oxygen species (ROS), acupuncture also repairs the DNA, lipids, and proteins attacked by ROS and mediates downstream of the ROS pathway to apoptosis.

Abstract
BACKGROUND Mild cognitive impairment (MCI) is defined as an intermediate stage between normal aging and Alzheimer's disease (AD), and early and easily available interventions to delay the progress of MCI to AD are necessary. Feasible complementary and alternative therapies such as electroacupuncture (EA), exercise, and cognitive training have shown some beneficial effects on MCI and AD. Here we report the protocol for a randomized controlled trial of the efficacy and safety of EA combined with computer-based cognitive rehabilitation (EA-CCR) for the treatment of MCI. METHODS The study will be a prospective, outcome assessor-blinded, parallel-arm, single-center (DongShin University Gwangju Korean Medicine Hospital, Republic of Korea), pilot randomized controlled clinical trial with a 1:1 allocation ratio. Participants with MCI will be randomized to a computer-based cognitive rehabilitation (CCR) or an EA-CCR group (n = 18 each). The CCR group will receive RehaCom cognitive rehabilitation once (30 min) a day, 3 days per week (excluding Saturday and Sunday) for 8 weeks. The EA-CCR group will receive EA at Baihui (GV20), Sishencong (EX-HN1), Fengchi (GB20), and Shenting (GV24) in addition to RehaCom cognitive rehabilitation once (EA:30 min, CCR:30 min) a day, 3 days per week (excluding Saturday and Sunday) for 8 weeks. The primary outcome will be an improvement in cognitive function assessed using the Korean version of the Alzheimer's Disease Assessment Scale-cognitive subscale. Scores for the Korean version of the Montreal Cognitive Assessment scale, Center for Epidemiological Studies Depression Scale, Korean Activities of Daily Living scale, Korean Instrumental Activities of Daily Living scale, and European Quality of Life Five Dimension Five Level Scale will be recorded as secondary outcome measures. All scores will be recorded at baseline (before intervention), 8 weeks after the first intervention (i.e., at the end of the intervention), and 12 weeks after completion of the intervention. DISCUSSION The study is expected to provide preliminary evidence regarding the efficacy, safety, and usefulness of EA-CCR for the treatment of MCI.

Abstract
Electroacupuncture is known as an effective adjuvant therapy in ischemic cerebrovascular disease. However, its underlying mechanisms remain unclear. Studies suggest that autophagy, which is essential for cell survival and cell death, is involved in cerebral ischemia reperfusion injury and might be modulate by electroacupuncture therapy in key ways. This paper aims to provide novel insights into a therapeutic target of electroacupuncture against cerebral ischemia/reperfusion injury from the perspective of autophagy. Here we review recent studies on electroacupuncture regulation of autophagy-related markers such as UNC-51-like kinase-1 complex, Beclin1, microtubule-associated protein-1 light chain 3, p62, and autophagosomes for treating cerebral ischemia/reperfusion injury. The results of these studies show that electroacupuncture may affect the initiation of autophagy, vesicle nucleation, expansion and maturation of autophagosomes, as well as fusion and degradation of autophagolysosomes. Moreover, studies indicate that electroacupuncture probably modulates autophagy by activating the mammalian target of the rapamycin signaling pathway. This review thus indicates that autophagy is a therapeutic target of electroacupuncture treatment against ischemic cerebrovascular diseases.

Abstract
Objectives To evaluate regulation of the endoplasmic reticulum stress (ERS) response by acupuncture and to investigate its neuroprotective effect on brain injury caused by heroin addiction. Methods A total of 48 male Sprague-Dawley rats were randomly divided into a healthy control group (Control), an untreated heroin exposed group (Heroin) and a heroin exposed group receiving electroacupuncture (EA) treatment at GV14 and GV20 (Heroin+acupuncture) with n=16 rats per group. A rat model of heroin addiction was established by intramuscular injection of incremental doses of heroin for 8 consecutive days. A rat model of heroin relapse was established according to the exposure (addiction) → detoxification method. Apoptotic changes in nerve cells in the hippocampus and ventral tegmental area (VTA) were evaluated in each group of rats using terminal deoxynucleotidyl transferase dUTP nick end labelling (TUNEL) assay. PERK, eIF2a, CHOP, IRE1 and JNK gene expression and protein expression were measured using quantitative real-time PCR (RT-qPCR) assay and immunohistochemical assay, respectively. Results The total number of positive nerve cells in the hippocampus and VTA was significantly lower in the Heroin+acupuncture group than in the Heroin group (p<0.01). Compared with the Heroin group, mRNA and protein expression of PERK, eIF2a, CHOP, IRE1 and JNK in the hippocampus and VTA were significantly downregulated in the Heroin+acupuncture group (p<0.05). Conclusion The acupuncture-regulated ERS response appears to mediate the neuroprotective effect of acupuncture in heroin-addicted rats with brain injury. Inhibition of CHOP and JNK upregulation and reduction of nerve cell apoptosis may be the main mechanisms underlying the effects of acupuncture on heroin addiction-induced brain injury.

Abstract
Background The hippocampus is vulnerable to severe damage after cerebral ischaemia–reperfusion (I/R) injury. This study aimed to explore the effect of electroacupuncture (EA) on cognitive impairment and its relationship with Ca2+neurotoxicity in a rat model of I/R injury induced by middle cerebral artery occlusion (MCAO). Methods 60 adult male Sprague-Dawley rats were randomly divided into three groups: control (sham surgery) group, untreated MCAO group and EA-treated MCAO+EA group. Rats in the MCAO and MCAO+EA groups underwent modelling of poststroke cognitive impairment by MCAO surgery. EA was performed for 30 min daily at GV20 and GV24 (1–20 Hz) for 1 week. The Morris water maze experiment was used to assess cognitive function. 2,3,5-triphenyl tetrazolium chloride staining was used to measure infarct volume. The intracellular Ca2+content in the Cornu Ammonis (CA)1 area of the hippocampus was assessed by laser confocal scanning microscopy. ELISA was performed to evaluate the concentration of glutamate (Glu) in the hippocampus, and the protein expression of two Glu receptors (N-methyl-D-aspartic acid receptor (NMDAR) 2A and NMDAR2B) were analysed by Western blotting. Results Compared with the untreated MCAO group, EA effectively ameliorated cognitive impairment (P=0.01) and shrunk the infarct volume (P=0.032). The content of intracellular Ca2+, Glu and NMDAR2B in the hippocampus was significantly raised by MCAO (P=0.031-0.043), while EA abrogated these effects. NMDAR2A was decreased by MCAO (P=0.015) but increased by EA (P=0.033). Conclusions EA had a beneficial effect on cognitive repair after cerebral I/R, and its mechanism of action likely involves a reduction of Ca2+influx via inhibition of Glu neurotoxicity and downregulation of NMDAR2B expression.

MicroRNA-96 is responsible for sevoflurane-induced cognitive dysfunction in neonatal rats via inhibiting IGF1R. Brain Res Bull 2018; 144:140-148.

Abstract
Sevoflurane is an experimental potent yet volatile anesthesia agent characterized by a low blood/gas partition coefficient. However, exposure to sevoflurane in neonatal mice has been speculated to result in learning deficits and abnormal social behavior. The aim of the present study was to investigate the relationship between sevoflurane and miR-96, in an attempt to identify the means by which it mediates IGF1R to influence the cognitive dysfunction (CD) in neonatal rats. Relationship between differentially expressed miRNAs and sevoflurane concentration was identified. The potential underlying regulatory mechanisms involved with sevoflurane were investigated through the administration of varying concentrations of the agent (1%, 2% and 4%), combined with miR-96 mimic or an inhibitor. A target prediction program was utilized, while the luciferase activity was determined in order to verify whether miR-96 targets IGF1R. The mRNA and protein levels of IGF1R, Bcl-2, Bax, and caspase-3 were measured followed by the determination of hippocampal neuron apoptosis. Learning and memory performance was assessed using the Morris water maze (MWM) test and step-down test. The obtained results highlighted a positive correlation between miR-96 and the concentration of sevoflurane, while miR-96 was confirmed to negatively target IGF1R. Our analyses indicated that 4% sevoflurane had a significantly stronger effect on reducing the levels of IGF1R and Bcl-2, while elevating the levels of miR-96, Bax and caspase-3 more so than that of 1% or 2% sevoflurane, which resulted in increased hippocampal neuron apoptosis but diminished the learning and memory performance of the rats. The addition of miR-96 mimic was demonstrated to exacerbate the influence of sevoflurane on hippocampal neurons as well as the cognitive function of the rats. The key findings of our study highlighted the role of miR-96 in the potential mechanism of sevoflurane anesthesia-induced CD in neonatal rats through the downregulation of IGF1R.

Abstract
BACKGROUND To evaluate whether electroacupuncture (EA) at Baihui (DU20) and Shenting (DU24) acupoints could improve cognitive function and enhance spontaneous low-frequency brain activity in rats with ischemic stroke. METHODS Total 36 rats were randomly divided into 3 groups-the sham surgery (Sham) group, the middle cerebral artery occlusion induced cognitive deficit (MICD) group, and the MICD with EA (MICD + EA) treatment group. The rats in MICD + EA group received EA treatment at DU20 and DU24 acupoints for 14 consecutive days after the surgery. The Morris water maze test was performed to assess the spatial learning and memory ability of the rats. Magnetic resonance imaging (MRI) was used to investigate the infarction volume and spontaneous low-frequency brain activity of each group. RESULTS After EA for 14 days, the learning and memory ability of the MICD rats was improved, and the brain infarction volume was reduced. Furthermore, basing on the fMRI amplitude of low-frequency fluctuation (ALFF) analysis, the decreased ALFF of the MICD rats was found in auditory cortex, cingulate gyrus, lateral nucleus group of dorsal thalamus, hippocampus, motor cortex, prelimbic cortex, retrosplenial cortex, and sensory cortex compared with the rats in sham group. However, these suppressive regions were notably attenuated after EA treatment. CONCLUSIONS Our results suggested that EA at DU20 and DU24 acupoints could ameliorate cognitive impairment in rats with ischemic stroke, and the protective effect of EA may attribute to reactivating the cognition-related brain regions, such as hippocampus, retrosplenial cortex, cingulate gyrus, prelimbic cortex, and sensory cortex.

Abstract
OBJECTIVE The aim of this systematic review was to assess the efficacy/effectiveness and safety of electroacupuncture (EA) in the treatment of post-stroke depression (PSD). METHODS A comprehensive literature search in the Pubmed, Embase, CENTRAL, ISI Web of Science, CNKI and Wanfang databases was conducted, and all relevant randomised controlled trials (RCTs) were screened for eligibility by two independent reviewers. The Cochrane Collaboration's tool and Jadad score were used to assess the risk of bias of included studies, and only RCTs scoring ≥3 were included in a meta-analysis. RESULTS 18 RCTs involving a total of 813 participants (mean age 61.6 years) in the EA groups and 723 participants (mean age 61.9 years) in the control groups were included. The included studies had an average 3 point Jadad score. PSD was diagnosed according to the Chinese Classification of Cerebrovascular Disease (CCCD) and the Chinese Classification of Mental Disease (CCMD) criteria. There was no significant difference between EA and antidepressants (fluoxetine 10-40 mg/day, citalopram 20 mg/day, sertraline 50 mg/day) in terms of the Hamilton Depression Rating Scale (HAMD) scores at week 4 after treatment (standardised mean difference (SMD) -0.11, 95% CI -0.31 to 0.10), at week 6 after treatment (SMD 0.04, 95% CI -0.43 to 0.51) or at week 8 after treatment (SMD -0.01, 95% CI -0.23 to 0.22). However, the combined incidence of adverse events in the EA groups was significantly lower than in the antidepressant groups (RR 0.21, 95% CI 0.14 to 0.33). CONCLUSION There was no significant difference between EA and antidepressants in the severity of depression, however EA caused fewer adverse events than antidepressants. Additional larger scale RCTs with rigorous study design are required.

Abstract
Although acupuncture therapy is increasingly used to treat diverse symptoms and disorders in humans, its underlying mechanism is not known well. Only recently have experimental studies begun to provide insights into how acupuncture stimulation generates and relates to pathophysiological responsiveness. Acupuncture intervention is frequently used to control pathologic symptoms in several visceral organs, and a growing number of studies using experimental animal models suggest that acupuncture stimulation may be involved in inducing anti-inflammatory responses. The vagus nerve, a principal parasympathetic nerve connecting neurons in the central nervous system to cardiovascular systems and a majority of visceral organs, is known to modulate neuroimmune communication and anti-inflammatory responses in target organs. Here, we review a broad range of experimental studies demonstrating anti-inflammatory effects of electroacupuncture in pathologic animal models of cardiovascular and visceral organs and also ischemic brains. Then, we provide recent progress on the role of autonomic nerve activity in anti-inflammation mediated by electroacupuncture. We also discuss a perspective on the role of sensory signals generated by acupuncture stimulation, which may induce a neural code unique to acupuncture in the central nervous system.

Abstract
Apoptosis, known as programmed cell death, plays a significant role in the pathogenesis of neurological diseases. Most of these diseases can be obviously alleviated by means of acupuncture treatment. Current research studies have shown that the efficacy of acupuncture to these medical conditions is closely associated with the anti-apoptotic potentials. Mainly based on the acupuncture's anti-apoptotic efficacy in prevalent neurological disorders, including cerebral ischemia-reperfusion injury, Alzheimer's disease, depression or stress related-modes, spinal cord injuries, etc., this review comes to a conclusion that the anti-apoptotic effect of acupuncture treatment for neurological diseases, evidently reflected through Bcl-2, Bax or caspase expression change, results from regulating mitochondrial or autophagic dysfunction as well as reducing oxidative stress and inflammation. The possible mechanisms of acupuncture's anti-apoptotic effect are associated with a series of downstream signaling pathways and the up-regulated expression of neurotrophic factors. It is of great importance to illuminate the exact mechanisms of acupuncture treatment for neurological dysfunctions.

Abstract
Using four-channel photoplethysmography (PPG) for acquiring peripheral arterial waveforms, this study investigated vascular and autonomic impacts of combined acupuncture-far infrared radiation (FIR) in improving peripheral circulation. Twenty healthy young adults aged 25.5 ± 4.6 were enrolled for 30-minute measurement. Each subject underwent four treatment strategies, including acupuncture at ST36 (Zusanli), pseudoacupuncture, FIR, and combined acupuncture-FIR at different time points. Response was assessed at 5-minute intervals. Area under arterial waveform at baseline was defined as AreaBaseline, whereas AreaStim referred to area at each 5-minute substage during and after treatment. AreaStim/AreaBaseline was compared at different stages and among different strategies. Autonomic activity at different stages was assessed using low-to-high frequency power ratio (LHR). The results demonstrated increased perfusion for each therapeutic strategy from stage 1 to stage 2 (all p < 0.02). Elevated perfusion was noted for all treatment strategies at stage 3 compared to stage 1 except pseudoacupuncture. Increased LHR was noted only in subjects undergoing pseudoacupuncture at stage 3 compared to stage 1 (p = 0.045). Reduced LHR at stage 2 compared to stage 1 was found only in combined treatment group (p = 0.041). In conclusion, the results support clinical benefits of combined acupuncture-FIR treatment in enhancing peripheral perfusion and parasympathetic activity.

Abstract
OBJECTIVE To explore the effects of electroacupuncture (EA) on the phosphorylated extracellular signal regulated kinase (p-ERK) pathway of the cerebral cortex in a rat model of focal cerebral ischaemia/reperfusion (I/R). METHODS 160 adult Sprague-Dawley rats underwent middle carotid artery occlusion (MCAO) to establish I/R injury and were randomly divided into four groups (n=40 each) that remained untreated (I/R group) or received EA at LU5, LI4, ST36 and SP6 (I/R+EA group), the ERK inhibitor PD98059 (I/R+PD group), or both interventions (I/R+PD+EA groups). An additional 40 rats undergoing sham surgery formed a healthy control group. Eight rats from each group were sacrificed at the following time points: 2 hours, 6 hours, 1 day, 3 days and 1 week. Neurological function was assessed using neurological deficit scores, morphological examination was performed following haematoxylin-eosin staining of cortical tissues, and apoptotic indices were calculated after terminal deoxyribonucleotidyl transferase (TdT)-mediated biotin-16-dUTP nick-end labelling. Cortical protein and mRNA expression of p-ERK and ERK were measured by immunohistochemistry and real-time quantitative PCR, respectively. RESULTS Compared with the I/R group, neurological deficit scores and apoptotic indices were lower in the I/R+EA group at 1 and 3 days, whereas mRNA/protein expression of ERK/p-ERK was higher in the EA group at all time points studied. CONCLUSION Our results suggest that EA can alleviate neurological deficits and reduce cortical apoptosis in rats with I/R injury. These anti-apoptotic effects may be due to upregulation of p-ERK. Moreover, apoptosis appeared to peak at 1 day after I/R injury, which might therefore represent the optimal time point for targeting of EA.

Abstract
BACKGROUND Acupuncture is a traditional method that has been widely used in various fields of medicine with therapeutic effect. However, evidence of effectiveness to support the application of electroacupuncture (EA) during the process of ischaemia is scarce. OBJECTIVES To investigate dynamic changes in hypoxia-inducible factor (HIF)-1α expression as well as its association with neurological status in rats subjected to acute ischaemic stroke and EA intervention. METHODS Forty adult male rats were randomly divided into three groups that received sham surgery (Control group, n=10) or underwent middle cerebral artery occlusion and EA (MCAO+EA group, n=15) or minimal acupuncture as a control treatment (MCAO+MA group, n=15). The rats in the MCAO+EA and MCAO+MA groups received EA or acupuncture without any electrical current, respectively, during 90 min of ischaemia. Rats in the Control group received the same surgical procedure but without MCAO. EA involved electrical stimulation of needles inserted into the quadriceps at 50 Hz frequency and 3 mA current intensity. Neurological status was evaluated on postoperative day 1, and cerebral infarction volume (IV) and HIF-1α expression 24 hours later. RESULTS Neurological scores were improved and cerebral IV was decreased in the MCAO+EA group compared to the MCAO+MA group (both p<0.05). Moreover, HIF-1α expression was higher in the MCAO+EA group versus the MCAO+MA group (p<0.05). CONCLUSIONS EA enhanced recovery of neurological function, decreased cerebral IV and increased HIF-1α expression in ischaemic rats. Further research is needed to determine whether EA is effective for stroke treatment through the stimulation of muscle contraction.

Abstract
Inflammation after stroke is the main cause of cerebral ischemia/reperfusion injury. Cascading events after injury can lead to cell death. Heat shock protein 70 and other endogenous injury-signaling molecules are released by damaged cells, which can lead to systemic stress reactions. Protecting the brain through repair begins with the stress-injury-repair signaling chain. This study aimed to verify whether acupuncture acts through this chain to facilitate effective treatment of ischemic stroke. Rat models of cerebral ischemia/reperfusion injury were established by Zea Longa's method, and injury sites were identified by assessing neurological function, 2,3,5-triphenyltetrazolium chloride staining, and hematoxylin-eosin staining. Electroacupuncture at acupoints Baihui (DU20) and Zusanli (ST36) was performed in the model rats with dilatational waves, delivered for 20 minutes a day at 2–100 Hz and an amplitude of 2 mA. We analyzed the blood serum from the rats and found that inflammatory cytokines affected the levels of adrenotrophin and heat shock protein 70, each of which followed a similar bimodal curve. Specifically, electroacupuncture lowered the peak levels of adrenocorticotrophic hormone and heat shock protein 70. Thus, electroacupuncture was able to inhibit excessive stress, reduce inflammation, and promote the repair of neurons, which facilitated healing of ischemic stroke.

Abstract
Vascular dementia (VaD) is the second leading type of dementia after Alzheimer's disease plaguing the aging population. Acupuncture has served as alternative and complementary medicine in the world for a long time and its use for VaD is based on a large body of preclinical and clinical researches. The mechanisms that underlie the protective effects of acupuncture are slowly beginning to be understood. Acupuncture influences multiple aspects of the pathological process of VaD. It improves cognitive function through protecting cerebral neurons from oxidative stress, apoptosis, and neuroinflammation, regulating glucose metabolism and neurotransmitters. Acupuncture may also improve synaptic plasticity and blood vessel function. It is likely that no single factor can explain the protection provided by acupuncture. This review provides a comprehensive overview of established and recent findings in animal-based researches aiming to elucidate the complex mechanisms of acupuncture on VaD.

Abstract
Objective
Herein, we evaluated the efficacy and safety of intra-arterial mild hypothermia in combination with arterial thrombolysis to treat acute cerebral infarction due to middle cerebral artery occlusion. Methods A total of 26 patients with acute middle cerebral artery occlusion were divided into a normothermia group (n = 15) and a mild hypothermia group (n = 11). The infarct volumes at 24 h and 7 days after the operation were compared between the normothermia group and the mild hypothermia group. Additionally, we compared neurological deficit scores between the two groups at 24 h, 7 days, and 1 mo after the operation. Results The infarct volumes and neurological deficit scores of the mild hypothermia group were significantly reduced compared to those in the normothermia group (p < 0.05). Furthermore, no adverse reactions or complications occurred in the mild hypothermia group. Conclusion Intra-arterial mild hypothermia reduced infarct volume after ischemia–reperfusion injury in the arterial thrombolysis of an acute cerebral infarction. Additionally, it improved the prognosis of patients with an acute middle cerebral artery occlusion, suggesting that this procedure is safe and effective for treating acute cerebral infarction.

Abstract
Angelicin is a member of a well-known class of chemical photosensitizes that have anticancer proper-ties in several cancer cell lines. However, the effects and the potential underlying mechanisms of angelicin action on human lung cancer cells remain unclear. Here, we report that angelicin has an essential role in inhibiting human lung carcinoma growth and metastasis. We found that angelicin markedly induced cell apoptosis and arrested the cell cycle in vitro. Angelicin also inhibited the migration of non-small cell lung cancer (NSCLC) A549 cells in a Transwell assay in a dose-dependent manner. In addition, after angelicin treatment, the expression levels of Bax, cleaved caspase-3 and cleaved caspase-9 were increased, and Bcl-2 expression was decreased. Moreover, our results indicate that angelicin inhibits NSCLC growth not only by downregulating cyclin B1, cyclin E1 and Cdc2, which are related to the cell cycle, but also by reducing MMP2 and MMP9 and increasing E-cadherin expression levels. Furthermore, extracellular signal-regulated kinase (ERK)1/2 and c-Jun NH2-terminal protein kinase (JNK)1/2 phosphorylation increased in parallel with the angelicin treatments. The inhibition of ERK1/2 and JNK1/2 by specific inhibitors significantly abrogated angelicin-induced cell apoptosis, cell cycle arrest and migration inhibition. We established in vivo A549 cell transplant and metastasis models and found that angelicin exerted a significant inhibitory effect on A549 cell growth and lung metastasis. Overall, our results suggested that angelicin is able to inhibit NSCLC A549 cell growth and metastasis by targeting ERK and JNK signaling, which demonstrates potential for NSCLC therapy.

Abstract
Background. The therapeutic mechanisms of cerebral ischemia treatment by acupuncture are yet not well addressed. Objective. We investigated the effects of electroacupuncture (EA) at GV26 observing the expression of autophagy-related proteins Beclin-1 and LC3B and proportion of apoptotic cells and Bcl-2 positive cells in MCAO/R model rats. Methods. Sprague-Dawley (SD) male rats were randomly assigned to 7 groups: model groups (M6h, M24h, and M72h), EA treatment groups (T6h, T24h, and T72h), and sham operation group (S). Neurological deficit and cerebral infarction volume were measured to assess the improvement effect, while the expression of Beclin-1 and LC3B and proportion of Tunel-positive and Bcl-2 positive cells were examined to explore EA effect on autophagy and apoptosis. Results. EA significantly decreased neurological deficit scores and the volume of cerebral infarction. Beclin-1 was significantly decreased in T24h, while LC3B-II/LC3B-I ratio markedly reduced in 6th hour. EA groups markedly reduced the number of Tunel positive cells, especially in T24h. Meanwhile, the number of Bcl-2 positive cells obviously increased after EA treatment, especially in T6h and T24h. Conclusions. The alleviation of inadequate autophagy and apoptosis may be a key mechanism involved in the reflex regulation of EA at GV26 to treat cerebral ischemia.

Abstract
Accumulating evidence demonstrates that acupuncture and electroacupuncture (EA) can exert a neuroprotective role for cerebral ischemia, but their precise mechanism remains largely unknown. Therefore, in this study, the effects of EA stimulation on cerebral ischemia reperfusion and its neuroprotective mechanisms were investigated. A rat model of middle cerebral artery occlusion (MCAO) was developed, and EA stimulation (2Hz, 1mA) at Baihui and Siguan acupoints was applied 30min after MCAO and then once daily for 7 consecutive days. The results indicated that EA stimulation significantly reduced the cerebral infarct area and neurological deficit scores, decreased the number of apoptotic cells, up-regulated Bcl-2 protein expression, and down-regulated Bax protein expression. EA stimulation resulted in a significant increase of proliferative cells in the cerebral tissues. Additionally, EA stimulation significantly down-regulated the expression levels of matrix metalloproteinase -9 (MMP-9) mRNA and protein, and simultaneously up-regulated the expression levels of tissue inhibitor of metalloproteinases-1 (TIMP-1) mRNA and protein, which resulted in an imbalance of MMP-9/TIMP-1expression, although it did not significantly change MMP-2 and TIMP-2 expression. These findings indicate that EA stimulation at Baihui and Siguan acupoints exerts a neuroprotective role against cerebral ischemia-reperfusion injury, which is probably associated with the inhibition of apoptosis and altering the balance of MMP-9/TIMP-1 expression.

Abstract
OBJECTIVE Mild cognitive impairment (MCI) is a pre-dementia state; 5-10% of cases per year will evolve into dementia. MCI can be amnestic (AMCI) or non-amnestic. AMCI is associated with a higher risk of progression. In recent years, interest in acupuncture as a potential treatment for AMCI has grown. The aim of this meta-analysis was to estimate the clinical effectiveness and safety of acupuncture for AMCI. METHODS Randomised controlled trials (RCTs) of acupuncture versus medical treatment for AMCI were identified using the following databases from inception to July 2015: PubMed; Medline; CENTRAL; Chinese Scientific Journal Database; The Chinese Acupuncture Trials Register; China National Knowledge Infrastructure (CNKI); and Wanfang database. Data were extracted from RCTs meeting the inclusive criteria according to Cochrane methods. Meta-analyses were conducted using Rev Man V.5.3 software. RESULTS Five trials involving 568 subjects were included. Meta-analysis showed that participants receiving acupuncture had better outcomes than those receiving nimodipine with greater clinical efficacy rates (odds ratio (OR) 1.78, 95% CI 1.19 to 2.65; p<0.01), mini-mental state examination (MMSE) scores (mean difference (MD) 0.99, 95% CI 0.71 to 1.28; p<0.01), and picture recognition score (MD 2.12, 95% CI 1.48 to 2.75; p<0.01). Meta-analysis also showed acupuncture in conjunction with nimodipine significantly improved MMSE scores (MD 1.09, 95% CI 0.29 to 1.89; p<0.01) compared to nimodipine alone. Three trials reported adverse events. Methodological quality of the included studies was judged to be generally poor. CONCLUSIONS Acupuncture appears effective for AMCI when used as an alternative or adjunctive treatment; however, caution must be exercised given the low methodological quality of included trials. Further, more rigorously designed studies are needed.
