RESUMO
Brown and white adipose tissue mediate thermogenesis through the thermogenetic centre of the brain, but safe methods for activating thermogensis and knowledge of the associated molecular mechanisms are lacking. We investigated body surface electroacupuncture stimulation (ES) at ST25 (targeted at the abdomen) induction of brown adipose thermogenesis and the neural mechanism of this process. Inguinal white adipose tissue (iWAT) and interscapular brown adipose tissue (iBAT) were collected and the thermogenic protein expression levels were measured to evaluate iBAT thermogenesis capacity. The thermogenic centre activating region and sympathetic outflow were evaluated based on neural electrical activity and c-fos expression levels. iWAT sensory axon plasticity was analysed with whole-mount adipose tissue imaging. ES activated the sympathetic nerves in iBAT and the c-fos-positive cells induced sympathetic outflow activation to the iBAT from the medial preoptic area (MPA), the dorsomedial hypothalamus (DM) and the raphe pallidus nucleus (RPA). iWAT denervation mice exhibited decreased c-fos-positive cells in the DM and RPA, and lower recombinant uncoupling orotein 1 peroxisome proliferator-activated receptor, ß3-adrenergic receptor, and tyrosine hydroxylase expression. Remodelling the iWAT sensory axons recovered the signal from the MPA to the RPA and induced iBAT thermogenesis. The sympathetic denervation attenuated sensory nerve density. ES induced sympathetic outflow from the thermogenetic centres to iBAT, which mediated thermogenesis. iWAT sensory axon remodelling induced the MPA-DM-RPA-iBAT thermogenesis pathway.

This study investigates the therapeutic potential of electroacupuncture (EA) on obesity, focusing on its influence on autophagy and energy metabolism, utilizing a high-fat diet (HFD)-induced mouse model. Treatment with EA significantly reduces body weight, fat deposition, and lipid accumulation in HFD-fed mice. Additionally, EA effectively ameliorates metabolic imbalances, reducing blood glucose levels and plasma markers of liver function. At the molecular level, EA enhances the expression of thermogenesis-associated genes in brown adipose tissue and decreases p53 expression, suggesting a decrease in apoptosis. Autophagy in white adipose tissue is inhibited by EA, as demonstrated by the suppression of key autophagy-related proteins. Further experiments highlight the critical role of Sirtuin 3 (Sirt3) in EA's anti-obesity effects. Sirt3 supplementation combined with EA results in reduced body weight, fat deposition, and lipid accumulation, along with modulations in key metabolic indicators. Moreover, EA's modulatory effect on uncoupling protein 1 (Ucp1), Peroxisome proliferator-activated receptor gamma coactivator 1-alpha (Pgc-1α), and p53 is found to be Sirt3 dependent. In conclusion, EA exerts beneficial effects against obesity through Sirt3-dependent modulation of autophagy and energy metabolism, indicating a potential therapeutic approach for obesity and related metabolic disorders.

Long-term high-fat diet (HFD) in adolescents leads to impaired hippocampal function and increases the risk of cognitive impairment. Studies have shown that HFD activates hippocampal microglia and induces hippocampal inflammation, which is an important factor for cognitive impairment. Electroacupuncture stimulation (ES), a nerve stimulation therapy, is anti-inflammatory. This study explored its therapeutic potential and mechanism of action in obesity-related cognitive impairment. 4-week-old C57 mice were given either normal or HFD for 22 weeks. At 19 weeks, some of the HFD mice were treated with ES and nigericin sodium salt. The cognitive behavior was assessed through Morris water maze test at 23 weeks. Western blotting was used to detect the expression levels of pro-inflammatory molecules IL-1ß and IL-1R, synaptic plasticity related proteins synaptophysin and Postsynaptic Density-95 (PSD-95), and apoptotic molecules (Caspase-3 and Bcl-2), in the hippocampus. The number, morphology, and status of microglia, along with the brain-derived neurotrophic factorï¼BDNFï¼ content, were analyzed using immunofluorescence. ES treatment improved cognitive deficits in HFD model mice, and decreased the expressions of microglial activation marker, CD68, and microglial BDNF. Inhibition of proinflammatory cytokine, IL-1ß, and IL-1R promoted PSD-95 and synaptophysin expressions. Peripheral NLRP3 inflammasome agonist injections exacerbated the cognitive deficits in HFD mice and promoted the expressions of IL-1ß and IL-1R in the hippocampus. The microglia showed obvious morphological damage and apoptosis. Collectively, our findings suggest that ES inhibits inflammation, regulates microglial BDNF, and causes remodeling of hippocampal function in mice to counteract obesity-like induced cognitive impairment. Overexcitation of peripheral inflammasome complexes induces hippocampal microglia apoptosis, which hinders the effects of ES.

Integrated traditional Chinese medicine (TCM) and Western medicine (WM) is a new medical science grounded in the knowledge bases of both TCM and WM, which then forms a unique modern medical system in China. Integrated TCM and WM has a long history in China, and has made important achievements in the process of clinical diagnosis and treatment. However, the methodological defects in currently published clinical practice guidelines limit its development. The organic integration of TCM and WM is a deeper integration of TCM and WM. To realize the progression of "integration" to "organic integration", a targeted and standardized guideline development methodology is needed. Therefore, the purpose of this study is to establish a standardized development procedure for clinical practice guidelines for the organic integration of TCM and WM to promote the systematic integration of TCM and WM research results into clinical practice guidelines in order to achieve optimal results as the whole is greater than the sum of the parts.

OBJECTIVE: To screen for differentially expressed serum microRNAs (miRNAs) in patients with diarrhea-predominant irritable bowel syndrome (IBS-D) compared with healthy participants and explore the mechanism of acupuncture in the treatment of IBS-D based on miRNAs. METHODS: IBS-D patients that met the Rome III diagnostic criteria and age- and sex-matched healthy participants were enrolled between April 2017 and December 2017. Serum miRNA levels were initially determined using a TaqMan low-density array (TLDA) in pooled samples. Markedly altered miRNAs in IBS-D patients were subsequently validated using quantitative real-time polymerase chain reaction (qRT-PCR) on individual samples. All IBS-D patients accepted the acupuncture therapy for 6 weeks. The disease severity was assessed using the IBS symptom severity scale (IBS-SSS) questionnaire before and after treatment. After acupuncture, the patients' serum was re-analyzed for altered expression of the miRNAs by qRT-PCR. RESULTS: TLDA and qRT-PCR analysis revealed six upregulated miRNAs (miR-1305, miR-575, miR-149-5p, miR-190a-5p, miR-135a-5p, and miR-148a-3p; P < 0.05) and two downregulated miRNAs (miR-194-5p, miR-127-5p; P < 0.05) in IBS-D patients compared with healthy controls. Post acupuncture treatment, total IBS-SSS scores, severity of abdominal pain, duration of abdominal pain, severity of abdominal distention, dissatisfaction with bowel habits and disruption in quality of life decreased significantly (P < 0.001). Furthermore, the upregulated miR-148a-3p levels in IBS-D patients also decreased significantly after acupuncture (P < 0.05). CONCLUSIONS: The over-expression or reduced expression of several miRNAs may contribute to IBS-D pathogenesis. Acupuncture might downregulate miR-148a-3p through multiple pathways to alleviate or relieve IBS-D symptoms. TRIAL REGISTRATION NUMBER: ChiCTR-IOR-17010860 (Chinese Clinical Trials Registry).

OBJECTIVE: To observe the effect of acupuncture combined with rehabilitation training on cognitive function and amino acid metabolism in children with cerebral palsy. METHODS: Twenty children with cerebral palsy (cerebral palsy group) were randomly divided into an acupuncture and rehabilitation group (11 cases) and a rehabilitation group (9 cases), and 10 healthy children were included as the normal group. The rehabilitation group was treated with rehabilitation training, 30 min each time; on the basis of rehabilitation training, the acupuncture and rehabilitation group was treated with acupuncture at Sishenzhen, Zhisanzhen, Naosanzhen, Niesanzhen, Dazhui (GV 14), Shenzhu (GV 12), Mingmen (GV 4), etc. The Sishenzhen (left and right points) and the ipsilateral Niesanzhen were respectively connected with a group of electrodes, intermittent wave, frequency of 2 Hz for 30 min. Both groups were treated once every other day, three times a week, totaling for 3 months. The Gesell developmental diagnostic scale (GESELL) was used to evaluate the developmental quotient (DQ) scores before and after treatment, and the blood samples of children with cerebral palsy before and after treatment and normal children were collected for amino acid metabolomics. RESULTS: Compared before treatment, the DQ scores of adaptation, fine motor and social in the acupuncture and rehabilitation group was increased after treatment (P<0.05), and the DQ score of fine motor in the rehabilitation group was increased after treatment (P<0.05). Compared with the normal group, the serum L-glutamate, L-ornithine, L-tyrosine, L-methionine and L-arginine in the cerebral palsy group were down-regulated, and L-histidine, L-citrulline, 5-hydroxylysine and L-glutamine were up-regulated before treatment. The functional pathways mapped by different metabolites between the cerebral palsy group and the normal group included arginine biosynthesis, arginine and proline metabolism, etc. Compared with the cerebral palsy group, the serum L-histidine was decreased, and L-citrulline showed decreasing trend in the acupuncture and rehabilitation group after treatment. CONCLUSION: Acupuncture combined with rehabilitation training could improve cognitive function in children with cerebral palsy, and the effect may be related to the down-regulation of L-histidine and L-citrulline metabolism.

Chronic low-grade inflammation of visceral adipose tissue can cause obesity-associated insulin resistance, leading to metabolic syndrome. However, anti-inflammatory drugs and those for obesity management can lead to serious side effects such as abnormal heart rate and blood pressure. Consequently, this study aimed to explore the therapeutic potential of electroacupuncture stimulation (ES) for obesity and associated chronic inflammation. Sprague-Dawley male rats were fed a high-fat diet (HFD) for ten weeks to build an obesity model, and half of the diet-induced obesity (DIO) rats were received ES. The levels of inflammatory factors were detected by ELISA and qPCR analysis. The nerve-associated macrophages were marked with immunofluorescence staining. The molecular mechanism of NLRP3 inflammasome in ES was determined by the NLRP3 inflammasome activation model. Compared to HDF rats, ES showed decreased body weight and chronic inflammatory damage. Specifically, this occurred via a decrease in monoamine oxidase-A (MAOA) expression, which suppressed noradrenaline degradation. MAOA is expressed in nerve-associated macrophages (NAMs), and ES attenuated NAMs by suppressing the NLRP3 inflammasome. The NLRP3 agonist blocked the noradrenaline degradation-reducing effect of ES, and an increase in lipolysis via the inhibition of the NLRP3 inflammasome attenuated NAMs. Thus, our findings suggest that ES induced lipolysis via activation of the NLRP3 inflammasome in nerve-associated macrophages (NAMs), independently of sympathetic nervous system activity.

INTRODUCTION: Cerebral palsy is the most common motor disability of childhood. Spastic cerebral palsy accounts for 60% to 70% of cases. Research has shown that acupuncture can improve the quality of life of children with cerebral palsy, but the mechanism of action remains unclear. This study aims to determine the effectiveness of acupuncture for treatment of children with spastic cerebral palsy and to assess the value of multimodal magnetic resonance imaging (MRI) and ambulatory electroencephalogram (EEG) for evaluation of treatment effect. METHODS AND ANALYSIS: This randomized controlled trial will enroll a total of 72 children with CP from 2 hospitals-Jiangsu Province Hospital of Chinese Medicine and Nanjing State Hospital of Pediatric-with 36 participants from each hospital. Patients will be randomly assigned (1:1 ratio) to receive "Tonifying Kidney and Invigorating Brain" acupuncture treatment plus standardized physical rehabilitation treatment (treatment group) or only standardized physical rehabilitation (control group). All participants will receive 3 treatment sessions per week for 3 consecutive months; they will then be followed up for another 3 months. The primary outcome measures will include multimodal magnetic resonance imaging (MRI), ambulatory electroencephalogram (EEG), and Gesell Developmental Diagnostic Schedules. The secondary outcome measures will include Gross Motor Function Classification System (GMFCS), Gross Motor Function Measure (GMFM), Functional Independence Measure (WeeFIM), and Modified Ashworth Scale score. Outcome measures (including primary and secondary outcome measures) were collected at the baseline, 3 months and 6 months prior to the intervention.Ethics and dissemination PATIENTS CONSENT:: Obtained. ETHICS APPROVAL: The central independent ethics committee of Jiangsu Province Hospital of Traditional Chinese Medicine approved the protocol (2017NL-115-02). SAFETY CONSIDERATIONS: Routine blood tests and liver and kidney function tests will be conducted to exclude patients with severe heart, liver, or kidney diseases. The same examinations will be performed again at the end of the study to detect any possible side effects. Possible acupuncture-related adverse events (e.g., fainting, needle stick injury, local infection, subcutaneous hematoma, and low-grade fever) will be documented. Serious adverse events will be reported to the principal investigator immediately. All unexpected and unintended responses, even those not necessarily related to the acupuncture intervention, will be documented as adverse events. CASE DROPOUT MANAGEMENT: Participants have a right to withdraw from the study at any time if they feel uncomfortable upon receiving the treatments or being diagnosed with serious complications or diseases. They will then be referred to the preferred department for further treatment and management. If cases of dropout, the researcher need to contact the participant to reason the problem out, collect and record all the necessary assessments on the last visit as well as the date of last visit. All data available until the date of withdrawal will be stored for further statistical analysis. DISCUSSION: This research is being conducted to assess the value of acupuncture as an intervention for rehabilitation of children with spastic cerebral palsy and also to evaluate the usefulness of multimodal MRI and ambulatory EEG for identifying changes in brain function. TRIAL REGISTRATION: This trial is registered with Chinese Clinical Trials Register, ChiCTR 1900024546 (registered 15 July 2019; retrospective registration, http://www.chictr.org.cn/showproj.aspx?proj=35763).

OBJECTIVE: To investigate the effect of electroacupuncture (EA) on irritable bowel syndrome (IBS) in mice through regulating nucleotide-binding oligomerization domain protein-like receptor family pyrin domain containing 6 (NLRP6). METHODS: Water-avoidance stress (WAS) mice model was used to investigate the effects and the mechanism of EA. Abdominal withdrawal reflex test, open field test, and intestinal motility test were used to evaluate visceral sensitivity, anxiety, and intestinal motility in mice. The expressions of NLRP6, Mucin-2 (MUC2) and E-cadherin were determined using immunofluorescence and Western blotting assays. RESULTS: EA significantly upregulated the expression of NLRP6 in the intestine of mice. Moreover, EA increased the expressions of MUC2 and E-cadherin in WAS mice. CONCLUSION: Our study found that the relief of IBS symptoms by EA may involve the increase in the expression of NLRP6 in WAS mice.

There is evidence to show that electro-acupuncture (EA) has a promotive effect on both lipolysis and thermogenesis, and that these mechanisms underlie the anti-obesity effect of EA. The sympathetic nervous system (SNS) is known to play a role in thermogenesis. Additionally, obesity is characterized by a chronic low-grade inflammatory state. Based on these findings, the aim of the present study is to investigate the potential neuro-immune mechanisms underlying the therapeutic effect of EA in obesity. In the experiment, we used a high fat diet (HFD) rats model to study the effect of EA in reducing body weight. EA increases the activity of sympathetic nerves in inguinal white adipose tissue (iWAT), especially in the HFD group. Compared to HFD rats, EA can decrease sympathetic associated macrophage (SAM) and the level of norepinephrine transporter protein (Slc6a2). The relative uncoupling protein 1 expression shows EA increases thermogenesis in iWAT, and increases ß3 receptors. Interestingly, injecting ß antagonist in iWAT increases Slc6a2 protein levels. Additionally, the SNS-macrophage cross-talk response to EA showed in iWAT but not in epididymis white adipose tissue. The results of the present study indicate that EA exerts its anti-obesity effect via three mechanisms: (1) inhibition of SAMs and the norepinephrine transporter protein SlC6a2, (2) promoting SNS activity and thermogenesis, and (3) regulating immunologic balance.
RESUMO
Post inflammatory irritable bowel syndrome (PI-IBS), a subset of IBS, is characterized by symptoms of visceral pain, bloating, and changed bowel habits that occur post initial episode of intestinal infection. Gut microbial dysbiosis or inflammation plays a key role in the pathogenesis of abdominal hypersensitivity of PI-IBS. Electroacupuncture (EA) stimulation results in an alleviated PI-IBS-associated symptom. This study investigated the effect of EA on IL-18 and gut microbial dysbiosis in one visceral hypersensitive rat models with PI-IBS. A trinitrobenzene sulfonic acid (TNBS)-induced visceral hypersensitivity rat model was developed. EA stimulation was applied to the ST25 and ST36 acupoints. Animals were assessed using abdominal withdrawal reflex (AWR) scores to determine the development of colonic visceral hypersensitivity. The 16S rRNA was used to correlate microbial diversity. IL-18 expression in colon was quantified by quantitative real-time PCR and western blotting. We identified that model rats had an increased visceral hypersensitivity to colorectal distention at different distention pressures compared with the normal group. Sensitivity to colorectal distention decreased after EA stimulation. The composition of the fecal microbiota was different between groups. Specifically, in the model group Empedobacter, Psychrobacter, Enterococcus, Butyricimonas, Vampirovibrio, Kurthia, Intestinimonas, Neisseria, Falsiporphyromonas, Bilophila, Fusobacterium, Alistipes, Veillonella, Flavonifractor, Clostridium XlVa were more abundant affected genera, whereas Lactobacillus was enriched in normal rats. EA stimulation was correlated with significant decrease in the phyla of Fusobacteria. The mRNA and protein levels of IL-18 were higher in the model group. Meanwhile, EA stimulation attenuated this response. In a word, our findings suggest that PI-IBS is associated with significant increase in IL-18 levels as well as an alteration in microbiome diversity. These changes can be reversed with EA treatment. EA stimulation has a positive effect in alleviating symptoms of visceral hypersensitivity and protecting the gastrointestinal tract.

Professor SHENG Can-ruo is a well-known national veteran doctor with over 70 years of clinical experience. He has unique academic thoughts and clinical experience for common diseases and some difficult and complicated diseases. This paper mainly introduces professor SHENG 's syndrome-differentiation thought and experience of acupoint selection for hot flashes. It is emphasized that common hot flashes, such as hot flashes and night sweats, are different between yin and yang. While regulating yin and yang, more attention should be paid to ying-wei harmony, which is not only suitable for women's perimenopausal syndrome, but also for a series of clinical diseases caused by refractory drugs such as endocrine therapy after breast cancer surgery. At the same time of acupoint selection based on syndrome differentiation, a more rational prescriptions should be made according to the duration of the disease and the experience acupoints to improve the clinical efficacy.

BACKGROUND: The role of protease-activated receptor 2 (PAR2) in the analgesic effect of electroacupuncture (EA) on visceral hypersensitivity (VH) in postinfectious irritable bowel syndrome (PI-IBS) has yet to be elucidated. AIM: In this study, we investigated the molecular mechanisms underlying the analgesic effect of EA in a rat model of PI-IBS. METHODS: Visceral hypersensitivity was evaluated by the abdominal withdrawal reflex test before and after administration of the PAR2 agonist, PAR2-AP, and/or EA. The protein expression and mRNA levels of PAR2, CGRP, SP, and TPSP in colon tissues were measured by immunofluorescence, western blot, and RT-PCR. RESULTS: We found that EA could alleviate VH and significantly decrease protein and mRNA levels of PAR2, TPSP, CGRP, and SP in PI-IBS rats. The analgesic effect of EA on VH was slightly reduced in the presence of PAR2-AP. CONCLUSIONS: These results suggest that EA alleviates VH symptoms through downregulation of the levels of the TPSP/PAR2/SP/CGRP signaling axis in colon tissues in PI-IBS rats. Together, our data suggests that PAR2 plays a critical role in the analgesic effect of EA on VH in PI-IBS.
RESUMO
BACKGROUND: Gastrointestinal motility disorder has been demonstrated to be regulated by acupuncture treatment. The mechanisms underlying the effects of acupuncture stimulation of abdominal and lower limb acupoints on gastrointestinal motility have been thoroughly studied; however, the physiology underlying the effects of acupuncture on the forelimbs to mediate gastrointestinal motility requires further exploration. The aim of this study was to determine whether electroacupuncture (EA) at LI11 promotes jejunal motility, whether the parasympathetic pathway participates in this effect, and if so, which somatic afferent nerve fibres are involved. METHODS: A manometric balloon was used to observe jejunal motility. The effects and mechanisms of EA at LI11 were explored in male Sprague-Dawley rats with or without drug administration (propranolol, clenbuterol, acetylcholine, and atropine) and with or without vagotomy. Three types of male mice (ß1ß2 receptor-knockout [ß1ß2-/-] mice, M2M3 receptor-knockout [M2M3-/-] mice and wild-type [WT] mice) were also studied by using different EA intensities (1, 2, 4, 6, and 8 mA). A total of 72 rats and 56 mice were included in the study. RESULTS: EA at LI11 increased the contractile amplitude of jejunal motility in the majority of both rats and mice. However, EA at LI11 did not enhance jejunal motility in rats administered atropine, rats that underwent vagotomy, and M2M3-||/- mice (at all intensities). In WT mice, EA at LI11 significantly increased jejunal motility at all intensities except 1 mA, and a plateau was reached at intensities greater than 4 mA. CONCLUSION: Our results suggest that EA at LI11 promotes jejunal motility primarily by exciting the parasympathetic pathway, and that Aδ-fibres and C-fibres may play important roles in the process.

Background. The roles of the sympathetic and parasympathetic systems in mediating the effect of electroacupuncture (EA) at ST37 on jejunal motility have yet to be demonstrated. Aim. We used rats and mice to investigate the effect and mechanism of action of EA at ST37 on jejunal motility. Methods. Jejunal motility was recorded by a balloon placed in the jejunum and connected to a biological signal collection system through a transducer. The effects of EA (3 mA) at ST37 were evaluated in Sprague-Dawley rats without drugs and with the administration of clenbuterol, propranolol, acetylcholine, and atropine. Further, the efficacy of EA at different intensities (1/2/4/6/8 mA) was measured in wild-type mice and ß1ß2-/- mice and M2M3-/- mice. Results. In Sprague-Dawley rats, the excitatory effect of EA at ST37 on jejunal motility disappeared in the presence of the muscarinic receptor antagonist atropine. EA at ST37 was less effective in M2M3-/- mice than in wild-type mice. Furthermore, to a certain extent, there existed "intensity-response" relationship between jejunal motility and EA. Conclusions. EA at ST37 can enhance jejunal motility in rats and mice mainly via excitation of the parasympathetic pathway. There is an "intensity-response" relationship between EA and effect on jejunal motility.
RESUMO
OBJECTIVE: To observe the clinical effect of acupuncture on obesity complicated with hyperlipidemia, and to explore the therapeutic differences among patients with different obesity levels. METHODS: A total of 1528 patients of obesity complicated with hyperlipidemia were enrolled into the study. According to the clinical symptoms and signs, they were treated with acupuncture according to the syndrome differentation. According to their obesity levels (A), body mass index (BMI) and body fat percentage (F%) before treatment, they were assigned into a mild obesity group, a moderate obesity group and a severe obesity group. The obesity index of body weight, A, BMI and F%, the blood lipid levels of total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL-C) and high density lipoprotein (HDL-C) were observed before and after treatment. The total efficacy, weight loss effect and lipid-lowering effect were evaluated. RESULTS: â The constituent ratio of severe obesity in male patients overweighted that of female patients (P<0.01), and the obesity was positively correlated with age and disease duration (r=0.145 and 0.164, both P<0.01). â¡ After treatment, the total effective rate was 98.9% (461/466), the weight loss rate was 99.4% (463/466) and lipid-lowering rate was 99.1% (462/466) in the mild obesity group, which were the all highest among three groups, indicating the lower obesity level achieved the better acupuncture efficacy. ⢠Acupuncture can significantly regulate the obesity index and blood lipid levels (all P<0.01); the obesity was negatively correlated with BMI and HDL-C (all P<0.01), and positively correlated with F%, TC, TG and LDL-C (all P<0.01). CONCLUSIONS: Acupuncture has dual effects on obesity and hyperlipidemia, which is significantly effective for patients with different obesity levels; acupuncture has the optimal effect on mild obesity, and had the optimal regulation on F% and blood lipid levels on severe obesity; acupuncture has superior overall regulation effects on obesity complicated with hyperlipidemia.
