[PMID: 38402930 DOI: 10.1016/j.ejphar.2024.176440] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2023] [Revised: 02/19/2024] [Accepted: 02/19/2024] [Indexed: 02/27/2024]
Abstract
This study investigated the effects of semaglutide (Sema) on the gut microbiota of obese mice induced with high-fat diet (HFD). Male C57BL/6 J mice aged 6 weeks were enrolled and randomly distributed to four groups, which were provided with a normal control diet (NCD,NCD + Sema) and a 60% proportion of a high-fat diet (HFD,HFD + Sema), respectively. HFD was given for 10 weeks to develop an obesity model and the intervention was lasted for 18 days. The results showed semaglutide significantly reduced body weight gain, areas under the curve (AUC) of glucose tolerance test and insulin resistance test, as well as adipose tissue weight in mice. Semaglutide effectively reduced lipid deposition and lipid droplet formation in the liver of obese mice, and regulated the expression of genes related to abnormal blood glucose regulation. Additionally, semaglutide influenced the composition of gut microbiota, mitigating the microbial dysbiosis induced by a high-fat diet by impacting the diversity of the gut microbiota. After the high-fat diet intervention, certain strains such as Akkermansia, Faecalibaculum, and Allobaculum were significantly decreased, while Lachnospiraceae and Bacteroides were significantly increased. However, the application of semaglutide restored the lost flora and suppressed excessive bacterial abundance. Moreover, semaglutide increased the content of tight junction proteins and repaired the damage to intestinal barrier function caused by the high-fat diet intervention. Furthermore, correlation analysis revealed inverse relationship among Akkermansia levels and weight gain, blood glucose levels, and various obesity indicators. Correlation analysis also showed that Akkermansia level was negatively correlated with weight gain, blood glucose levels and a range of obesity indicators. This phenomenon may explain the anti-obesity effect of semaglutide, which is linked to alterations in gut microbiota, specifically an increase in the abundance of Akkermansia. In summary, our findings indicate that semaglutide has the potential to alleviate gut microbiota dysbiosis, and the gut microbiota may contribute to the obesity-related effects of this drug.

Electroacupuncture for weight loss by regulating microglial polarization in the arcuate nucleus of the hypothalamus. Life Sci 2023; 330:121981. [PMID: 37516430 DOI: 10.1016/j.lfs.2023.121981] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2023] [Revised: 07/21/2023] [Accepted: 07/24/2023] [Indexed: 07/31/2023]
Abstract
Electroacupuncture (EA) has a weight loss effect, but the underlying molecular mechanisms of weight loss with EA have not been fully elucidated. This study aimed to investigate the modulatory effects of EA on the phenotype of hypothalamic microglia in obese mice. A total of 50 male C57BL/6J mice were used in this study. There were three groups in this experiment: The conventional diet group (Chow group), the high-fat diet group (HFD group), and the EA intervention group (HFD + EA group). EA was applied at "Tianshu (ST25)", "Guanyuan (RN4)", "Zusanli (ST36)" and "Zhongwan (RN12)" every day for 10 min. Hematoxylin and eosin (H&E) staining, immunohistochemical staining, and real-time PCR were applied in this study. The results showed that EA intervention was associated with a decrease in body weight, food intake, adipose tissue weight, and adipocyte size. At the same time, EA induced microglia to exhibit an M2 phenotype, representing reduced iNOS/TNF-α and increased Arg-1/IL-10/BDNF, which may be due to the promotion of TREM2 expression. EA also reduced microglia enrichment in the hypothalamic arcuate nucleus and declined TLR4 and IL-6, inhibiting microglia-mediated neuroinflammation. In addition, EA treatment promoted POMC expression, which may be associated with reduced food intake and weight loss in obese mice. This work provides novel evidence of EA against obesity. However, further study is necessary of EA as a therapy for obesity.

Abstract
The prevalence of obesity has reached pandemic dimensions. It is associated with multiple comorbidities and is becoming a clinical and public health threat. Obesity is a multifactorial disease with a complex pathophysiology and interplay of various systems. A strong interplay exists between the neuro-endocrine system, the immune system with systemic chronic low-grade inflammation, and microbiome dysbiosis that can lead to the development of obesity, which in turn can exacerbate each of these factors, hence creating a vicious cycle. The conventional treatment with lifestyle modifications such as diet, physical exercise, pharmacotherapy, and bariatric surgery does not always result in sufficient weight control thus paving the way for other strategies. As one such strategy, acupuncture is increasingly used worldwide to treat obesity. This narrative review outlines the evidence for this neuro-endocrine-immune interplay in the pathophysiology of obesity. Furthermore, the existing experimental and clinical evidence of acupuncture as a multi-targeted therapy for obesity is explained and future research perspectives are discussed.

Abstract
Objective Obesity is an epidemic with an increasing prevalence in developing countries. The condition affects almost all physiologic functions of the body and is a significant threat to public health. Treatment of obesity is often difficult and expensive. Pharmacologic therapy has many side-effects. Acupuncture, a nonpharmacologic therapy, has shown promising results for treating obesity. Electroacupuncture (EA) and thread-embedded acupuncture (TEA) can be used. The aim of this study was to analyze the therapeutic effects of EA and TEA, using polydioxanone (PDO), on weight loss, waist circumference, and plasma-leptin concentrations in obese patients undergoing a dietary intervention. Materials and Methods This single-blinded, randomized clinical trial randomized 34 subjects into 2 groups: EA and TEA. In the EA group, EA was administered 3 times per week for 4 weeks (a total of 12 sessions). In the TEA group, EA was administered only once. Body weight and waist circumference were measured at baseline, and on days 3, 7, 14, 21, and 28 (end) of the trial. Plasma-leptin concentrations were measured at the beginning and end of the trial. Results There was a significant decrease in body weight and waist circumference in the groups before and after treatment (P < 0.001), and a significant decrease in plasma-leptin concentrations in the EA (P = 0.012) and TEA groups (P = 0.001). There were no significant differences between the groups in weight loss (P = 0.621), waist circumference (P = 0.545), and plasma-leptin concentration (P = 0.784). Conclusions EA and PDO TEA are equally effective for reducing body weight, waist circumference, and plasma-leptin concentrations in obese patients undergoing dietary interventions. However, TEA is more time-efficient than EA.

Abstract
Lipid metabolism disorder plays a fundamental role in the pathogenesis of atherosclerosis. As the largest metabolic organ of the human body, liver has a key role in lipid metabolism by influencing fat production, fat decomposition, and the intake and secretion of serum lipoproteins. Numerous clinical and experimental studies have indicated that the dysfunction of hepatic lipid metabolism is closely tied to the onset of atherosclerosis. However, the identity and functional role of hepatic lipid metabolism responsible for these associations remain unknown. This review presented that cholesterol synthesis, cholesterol transport, and the metabolism of triglyceride, lipoproteins, and fatty acids are all associated with hepatic lipid metabolism and atherosclerosis. Moreover, we also discussed the roles of gut microbiota, inflammatory response, and oxidative stress in the pathological association between hepatic lipid metabolism and atherosclerosis. These significant evidences support strongly that hepatic lipid metabolism disorders may increase the risk of atherosclerosis.

Abstract
Obesity and related diseases are considered as pandemic representing a worldwide threat for health. Animal models are critical to validate the effects and understand the mechanisms related to classical or innovative preventive and therapeutic strategies. It is, therefore, important to identify the best animal models for translational research, using different evaluation criteria such as the face, construct, and predictive validity. Because the pharmacological treatments and surgical interventions currently used for treating obesity often present many undesirable side effects, relatively high relapse probabilities, acupuncture, electroacupuncture (EA), and related therapies have gained more popularity and attention. Many kinds of experimental animal models have been used for obesity research studies, but in the context of acupuncture, most of the studies were performed in rodent obesity models. Though, are these obesity rodent models really the best for acupuncture or related therapies research studies? In this study, we review different obesity animal models that have been used over the past 10 years for acupuncture and EA research studies. We present their respective advantages, disadvantages, and specific constraints. With the development of research on acupuncture and EA and the increasing interest regarding these approaches, proper animal models are critical for preclinical studies aiming at developing future clinical trials in the human. The aim of the present study is to provide researchers with information and guidance related to the preclinical models that are currently available to investigate the outcomes of acupuncture and related therapies.

Abstract
The underlying mechanism of electroacupuncture (EA) in relieving obesity, anti-inflammation and the interaction with metabolic pathways in obese mice has not been elaborated. The aim of this study was to investigate the regulation of EA on macrophage polarization in obesity tissue of diet-induced obesity mice. Mice were divided in 6 groups: normal control group, model group, EA-7 group, EA-14 group, EA-21 group and EA-28 group. Low-frequency EA was applied at "Tianshu (ST 25)", "Guanyuan (CV 4)", "Zusanli (ST 36)" and "Sanyinjiao (SP 6)" for 10 min. Adipose tissue was assessed with hematoxylin and eosin staining. Adipocytokines and pro-inflammatory factors expression was measured by ELISA. The protein and mRNA levels of macrophage markers were examined by immumohistochemical staining and RT-PCR, respectively. EA treatment was associated with a decrease of adipose tissue and large adipocytes, and an increase of small adipocytes. After EA treatment, the levels of Leptin, Chemerin, TNF-α, F4/80, iNOS, and CD11c decreased obviously in adipose tissue, while IL-4, IL-10 and CD206 levels increased significantly. Besides, TNF-α in spleen tissue was also downregulated, but IL-4 and IL-10 were upregulated. EA prevents weight gain through modulation inflammatory response and macrophage polarization in obese adipose tissues.

Abstract
PURPOSE To assess the effects of electro-acupuncture (EA) on glycemic control, myocardial inflammation, and the progression of diabetic cardiomyopathy in mice with type 2 diabetes. METHODS Db/Db mice received EA at PC6+ST36 (DM-Acu), non-acupoint simulation (DM-Sham), or no treatment (DM). EA was applied for 30 min per day, 5 days a week for 4 weeks. Heart function was assessed by echocardiography. Myocardium was assessed by RT-PCR, immunoblotting, and histology. Serum TNF-α, IL-1α, IL-1β, IL-6, and IL-8 were measured. RESULTS DM-Acu, but not DM-Sham, reduced fasting blood glucose without affecting body weight. DM decreased systolic function. DM-Acu, but not DM-Sham, attenuated the decrease in systolic function. Heart weight was significantly smaller in the DM-Acu than in the DM and DM-Sham groups. Percent fibrosis and apoptosis were reduced in the DM-Acu, but not the DM-Sham, group. Serum levels of IL-1α, IL-1β, IL-6, IL-8, ICAM-1, MCP-1, and TNF-α were significantly lower in the DM-Acu than in the DM or DM-Sham groups. Protein levels of P-Akt and P-AMPK and mRNA levels of phosphoinositide-3-kinase regulatory subunit 6 (PIK3r6) were significantly higher in the DM-Acu group. Myocardial mRNA and protein levels of insulin-like growth factor 1 receptor (IGF1R) were significantly lower in the DM and DM-Sham groups compared with the DM-Acu group. CONCLUSIONS EA reduced serum glucose; prevented DM-induced hypertrophy and deterioration of systolic function, inflammation, and fibrosis; and restored IGF1R, P-Akt, and P-AMPK levels in mice with type 2 diabetes mellitus.

Abstract
OBJECTIVE The aim of this study was to examine the effect of acupuncture on obesity-related parameters with regard to metabolomics. METHODS This two-arm parallel, patient- and assessor-blind, sham-controlled randomized clinical trial included 120 obese participants. Participants were randomized into two groups. The treatment group received a combined intervention of manual acupuncture (MA) plus electroacupuncture (EA), while the control group received a combination of sham acupuncture interventions consisting of sham MA plus sham EA for 6 weeks. The serum lipid levels were measured as the primary outcome measure and anthropometric parameters and serum metabolic profiles including amino acids and carnitines were measured as secondary outcome measures. RESULTS The serum lipid levels and anthropometric measurements did not significantly differ between groups, while body weight, body mass index (BMI), and waist circumference were improved within each group and the level of high-density lipoprotein cholesterol increased over time in the treatment group. There were no significant differences in amino acid levels between groups, while certain carnitine (C2, C4, C6, and l-carnitine) levels were significantly increased (p < 0.05) in the treatment group compared to the control group. CONCLUSION In summary, 6 weeks of acupuncture treatment did not affect anthropometric and serum metabolic parameters, with the exception of certain carnitines, when compared to sham acupuncture. The observation of increased carnitine levels in the acupuncture group could result in potential long-term benefits to obese individuals. Additional studies are needed to investigate the long-term effects of acupuncture on lipid metabolism and the underlying mechanism of action. TRIAL REGISTRATION NUMBER This study is registered at ClinicalTrials.gov (NCT02066090).

Abstract
OBJECTIVE To investigate whether auricular acupuncture (AA) attenuates bodyweight and obese inflammation through the release of irisin from muscle tissue in mice. METHODS Sixty 4-week-old mice were fed a high fat diet (HFD) for 4 weeks. These animals were divided into six groups that remained untreated (HFD) or underwent electrical AA (HFD+EAA), sham EAA (HFD+SEAA), adrenalectomy (HFD+AD), adrenalectomy and EAA (HFD+AD+EAA), or adrenalectomy and injection of recombinant lentivirus expressing fibronectin type III domain-containing protein 5 (rFNDC) (HFD+AD+rFNDC) in the ninth week. The EAA and SEAA were performed at two traditional auricular acupuncture points daily for 4 weeks. An additional 10 mice fed a control diet were included as a normal control (NC) group. At the end of the study, norepinephrine (NE) in the serum, tumour necrosis factor α (TNFα) and interleukin 1β (IL-1β) in the serum and white adipose tissue, irisin in the serum and muscle, uncoupling protein-1 (UCP-1) in the brown adipose tissue (BAT), and FNDC5 in the muscle, were analysed. RESULTS The AD+EAA group exhibited better control of bodyweight and inflammation compared with the AD+SEAA and untreated HFD model groups (P<0.05), especially regarding the increased expression of NE, FNDC5, irisin and UCP-1 (P<0.05). After adrenalectomy, mice receiving EAA had less NE, FNDC5, irisin and UCP-1 as well as greater expression of inflammatory cytokines and bodyweight. However, lentiviral overexpression of rFNDC successfully reversed this situation in the AD mice and mimicked the effects of EAA on bodyweight, inflammation and expression of FNDC5, irisin and UCP-1, although it did not impact NE. CONCLUSIONS EAA promoted NE release from the adrenal gland leading to further expression of FNDC5, irisin and UCP-1, which contributed to weight management and inflammatory inhibition.

Electroacupuncture Upregulated Ghrelin in Rats with Functional Dyspepsia via AMPK/TSC2/Rheb-Mediated mTOR Inhibition. Dig Dis Sci 2020; 65:1689-1699. [PMID: 31863340 PMCID: PMC7225202 DOI: 10.1007/s10620-019-05960-5] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/14/2018] [Accepted: 11/13/2019] [Indexed: 02/07/2023]
Abstract
BACKGROUND Gastrointestinal motility disorder is an important pathological basis for functional dyspepsia (FD). Epigastric ache and discomfort are the main symptoms of FD, and ghrelin deficiency is closely related to the occurrence and development of FD. While electroacupuncture (EA) alleviated the symptoms of FD patients and improved their quality of life, there is a lack of sufficient mechanistic evidence to support these beneficial effects. METHODS An in vivo FD model was established in wild-type and mammalian target of rapamycin (mTOR) knockout (-/-) rats. FD rats were subjected to EA with or without mTOR agonists or inhibitors. Gastric emptying and intestinal propulsion were assessed, and pathological changes in the hypothalamus, gastric antrum, and small intestine were examined histologically. In addition, ghrelin expression and AMPK/TSC2/Rheb/mTOR activation were detected by quantitative reverse transcription polymerase chain reaction and western blot. RESULTS EA alone or in combination with mTOR inhibitors improved gastrointestinal function in FD rats by increasing the rates of intestinal propulsion and gastric emptying, and pathological changes in the hypothalamus, gastric antrum, and small intestine were alleviated. This may be related to the significant upregulation of ghrelin expression and the effective activation of the AMPK/TSC2/Rheb/mTOR signaling pathway. Interestingly, EA also improved gastrointestinal function and ghrelin expression in mTOR (-/-) KO FD rats. CONCLUSION Altering the level of ghrelin by regulating AMPK/TSC2/Rheb-mediated mTOR inhibition is an important way through which EA treats FD. The complex EA-mediated regulatory mechanisms of the brain-gut axis still require further exploration.

Acupuncture for type 2 diabetes mellitus: A systematic review and meta-analysis of randomized controlled trials. Complement Ther Clin Pract 2019; 36:100-112. [PMID: 31383426 DOI: 10.1016/j.ctcp.2019.04.004] [Citation(s) in RCA: 28] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2019] [Revised: 04/12/2019] [Accepted: 04/24/2019] [Indexed: 12/11/2022]
Abstract
BACKGROUND Acupuncture has been used to treat type 2 diabetes (T2DM) for 2000 years and there are emerging clinical evidence and animal studies for its efficacy. However, we are unable to conclude the effectiveness and safety on this issue yet. OBJECTIVES To assess the effects and safety of acupuncture for T2DM. METHODS We systematically searched 5 databases and 2 clinical registry platforms from inception to 2018-6-4. RCTs for acupuncture or its variants compared with sham acupuncture or no acupuncture controls for T2DM were included. The primary outcomes were glycemic control and adverse events. RESULTS A total of 21 studies, which comprised a total of 1943 participants, were included in the final meta-analysis. Compared with sham acupuncture or no acupuncture plus baseline treatments, acupuncture plus baseline treatments yield reduction in FBG(MD 1.21 mmol/l, 95%CI 1.56 to 0.87), 2 h BG(MD 2.13 mmol/l, 95%CI 2.79 to 1.46), HA1c (MD 1.12%, 95%CI 1.62 to 0.62). Our results also show acupuncture can improve blood lipids and blood pressure control, and reduce weight. CONCLUSIONS As one type of multifactorial intervention, acupuncture could be recommended as a supplementary treatment in the management of T2DM, especially in those with obesity or metabolic disorders. However, due to the small sample size, poor methodological quality of trials reviewed, the amount of evidence is not fully convincing. There is a need for well-planned, long-term studies.

The Effectiveness of Acupoint Catgut Embedding Therapy for Abdominal Obesity: A Systematic Review and Meta-Analysis. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2019; 2019:9714313. [PMID: 31341504 PMCID: PMC6612388 DOI: 10.1155/2019/9714313] [Citation(s) in RCA: 32] [Impact Index Per Article: 6.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/23/2019] [Revised: 04/25/2019] [Accepted: 05/09/2019] [Indexed: 11/18/2022]
Abstract
Acupoint catgut embedding is a useful therapy for weight management and widely applied in China. This review aimed to systematically evaluate the effects of acupoint catgut embedding on abdominal obesity. We searched the PubMed, Cochrane-Library, Embase, OVID, MEDLINE, ISI (web of science), Wanfang, VIP, CBM, and CNKI for randomized controlled trials that used acupoint catgut embedding to treat abdominal obesity before April 2019 with the language restriction of Chinese and English. The combination subject terms of abdominal obesity (or central obesity) and acupoint catgut embedding (or catgut implantation, catgut embedding) were used. We found 15 studies involving 1584 individuals. When acupoint catgut embedding plus electroacupuncture is compared with electroacupuncture alone, significant reductions in improvement rate (RR = 1.03, 95% CI = 0.99~1.08), body weight (MD = 5.20, 95%CI = 1.16~9.25), body mass index (MD = 1.73, 95%CI = 0.70~2.76), waist circumference (MD = 2.91, 95%CI = 1.36~4.46), and hip circumference (MD = 1.06, 95%CI = -0.18~2.30) were found. Mean values of body weight by acupoint catgut embedding were 1.35 kg compared with electroacupuncture. Less adverse events were reported in all included articles. In summary, pooled outcomes of acupoint catgut embedding presented a tendency of equal effects to other kinds of acupuncture, whereas acupoint catgut embedding plus electroacupuncture is more effective for abdominal obesity. This study is registered with PROSPERO 2017 (CRD42017082357).

Abstract
Objectives: To investigate the anti-atherogenic effect of moxibustion and whether it is mediated through the reverse cholesterol transport process. Methods: 8-week-old male apolipoprotein E deficient (ApoE−/− knockout) mice were randomly divided into two groups (n=10 per group): atherosclerosis (AS) and AS plus moxibustion (AS+M). C57BL/6J mice of the same background (n=10) were selected as controls. Mice in the AS+M group received indirect moxibustion with an ignited moxa stick held over CV4. Mice of the AS and control groups were restrained in the same holder with an unlit moxa stick held over CV4. All treatments were performed for 20 min per day, 6 days per week for 12 weeks. After the treatment, the mice were euthanased and their serum lipids were measured. The aortic roots and thoracic aortas were collected for haematoxylin and eosin and red oil O staining, respectively, to analyse the atherosclerotic lesions. Expression of adenosine triphosphate binding cassette (ABCA)A1/G1 and liver X receptor α (LXRα) in the thoracic aorta were examined with Western blotting. Results: The moxibustion-treated (AS+M) mice showed a significantly lower plaque area percentage in the aortic root and thoracic aorta, and higher expression of LXRα and ABCA1 in the thoracic aorta compared with the AS mice. No significant differences were found in average lipid area percentage in the thoracic aorta, or ABCG1 expression in the thoracic aorta, between mice in the AS+M and AS groups. Conclusion: Moxibustion treatment at CV4 suppressed the progression of atherosclerotic lesions in ApoE−/− mice. The anti-atherogenic effect of moxibustion may be achieved by: (1) regulation of lipid metabolism, and thus prevention of lipid accumulation; and (2) upregulation of LXRα- and ABCA1-mediated cholesterol efflux in the lesion area.

Abstract
Simple obesity is a worldwide epidemic associated with rapidly growing morbidity and mortality which imposes an enormous burden on individual and public health. As a part of Traditional Chinese Medicine (TCM), acupuncture has shown the positive efficacy in the management of simple obesity. In this article, we comprehensively review the clinical and animal studies that demonstrated the potential mechanisms of acupuncture treatment for simple obesity. Clinical studies suggested that acupuncture regulates endocrine system, promotes digestion, attenuates oxidative stress, and modulates relevant molecules of metabolism in patients of simple obesity. Evidence from laboratory indicated that acupuncture regulates lipid metabolism, modulates inflammatory responses, and promotes white adipose tissue browning. Acupuncture also suppresses appetite through regulating appetite regulatory hormones and the downstream signaling pathway. The evidence from clinical and animal studies indicates that acupuncture induces multifaceted regulation through complex mechanisms and moreover a single factor may not be enough to explain the beneficial effects against simple obesity.

Abstract
OBJECTIVE To investigate the effect of electroacupuncture (EA) on endothelial dysfunction related to high fat diet (HFD)-induced insulin resistance through the phosphatidylinositol 3-kinase (PI3K)-protein kinase B (Akt) signalling pathway. METHODS Twenty-four male Sprague-Dawley rats were fed a regular diet (Control group, n=8) or a HFD (n=16) for 12 weeks to induce an insulin resistance model. HFD-fed rats were divided into two groups that remained untreated (HFD group, n=8) or received electroacupuncture (HFD+EA group, n=8). EA was applied at PC6, ST36, SP6 and BL23. At the end of the experiment, fasting blood glucose (FBG), serum insulin (FINS), serum C-peptide (C-P) and homeostatic model assessment of insulin resistance (HOMA-IR) indices were determined. Pancreatic islet samples were subjected to histopathological examination. The thoracic aorta was immunostained with anti-rat insulin receptor substrate (IRS)-1, Akt and endothelial nitric oxide synthase (eNOS) antibodies. mRNA and protein expression of IRS-1, PI3K, Akt2 and eNOS in the vascular endothelium were determined by real-time PCR and Western blot analysis, respectively. RESULTS The bodyweight increase of the HFD+EA group was smaller than that of the untreated HFD group. Compared with the HFD group, the levels of FBG, FINS, C-P and HOMA-IR in the HFD+EA group decreased significantly (P<0.01). Histopathological evaluation indicated that EA improved pancreatic islet inflammation. The expression of endothelial markers, such as IRS-1, PI3K, Akt2 and eNOS, decreased in the HFD group, while EA treatment appeared to ameliorate the negative impact of diet. CONCLUSION EA may improve insulin resistance and attenuate endothelial dysfunction, and therefore could play a potential role in the prevention or treatment of diabetic complications and cardiovascular disease through the PI3K/Akt signalling pathway.

Abstract
Addressing the global obesity epidemic requires innovative approaches that are also acceptable to affected individuals. There is growing evidence suggesting that food addiction, one contributor to obesity, bears many similarities to drug and alcohol addiction, presenting a potential role for addiction-focused acupuncture as a novel treatment modality. In this perspective article, we begin by briefly reviewing the evidence linking food and drug/alcohol addiction. We then describe the development of an acupuncture-based protocol for treating opioid addiction in Hong Kong in the 1970s and discuss the evidence base for acupuncture's efficacy in treating a range of substance use disorders. Next, we describe acupuncture's proposed mechanism of action in attenuating withdrawal and promoting abstinence. Finally, we note the dearth of studies specifically examining the effectiveness of acupuncture in treating food addiction and suggest that more research should focus in this area as part of the effort to combat rising rates of obesity worldwide.

Abstract
BACKGROUND Complementary therapies may increase the success rate of weight loss via a calorie-restricted diet. Acupuncture is a popular complementary therapy for obesity management. To our knowledge, no studies have summarised the effects of laser acupuncture (LA) on obesity. OBJECTIVE To evaluate the efficacy of LA, in particular with respect to its impact on anthropometric features and appetite in obese adults, by conducting a systematic review of previous clinical trials. METHODS We searched PubMed/Medline, Scopus, Web of Science, the Cochrane Library, Embase and Google Scholar electronic databases for papers published through October 2016. All clinical trials in English containing either anthropometric indices or appetite parameters were included. Two reviewers independently examined studies based on a predefined form for data extraction and the Jadad scale for quality assessment in order to minimise bias throughout the evaluation. RESULTS After screening the papers, seven clinical trials met the criteria and were included in the systematic review. Positive effects of LA therapy were seen in body weight (n=3), body mass index (n=5), waist circumference (n=4), hip circumference (n=3), waist to hip ratio (n=4) and % fat mass (n=3). Appetite parameters were reported in one study, which showed that LA can reduce appetite and increase the sensation of feeling full. CONCLUSION Although some studies have indicated beneficial effects for LA on obesity, the lack of evidence with high methodological quality made it impossible to reach a definitive conclusion about the efficacy of LA for obesity management. Further high-quality, randomised, sham-controlled clinical trials with a larger sample size are needed to shed light on the efficacy of LA for obesity management and weight maintenance.

Abstract
Fructus schisandrae (Wuweizi in Chinese), a common traditional Chinese herbal medicine, has been used for centuries to treat chronic liver disease. The therapeutic efficacy of Wuweizi has also been validated in clinical practice. In this study, molecular docking and network analysis were carried out to explore the hepatoprotective mechanism of Wuweizi as an effective therapeutic approach to treat liver disease. Multiple active compounds of Wuweizi were docked with 44 protein targets related with viral hepatitis, fatty liver, liver fibrosis, cirrhosis, and liver cancer. A compound-target network was constructed through network pharmacology analysis, predicting the relationships of active ingredients to the targets. Our results demonstrated that schisantherin, schisandrin B, schisandrol B, kadsurin, Wuweizisu C, Gomisin A, Gomisin G, and angeloylgomisin may target with 21 intracellular proteins associated with liver diseases, especially with fatty liver disease. The CYP2E1, PPARα, and AMPK genes and their related pathway may play a pivotal role in the hepatoprotective effects of Wuweizi. The network pharmacology strategy used provides a forceful tool for searching the action mechanism of traditional herbal medicines and novel bioactive ingredients.

Abstract
Acupuncture is reported to be effective in treating obesity related illnesses, but its mechanism is still unclear. To investigate this mechanism we applied electro-acupuncture (EA) in a mouse model of obesity and used RNA-seq to identify molecular consequences. Deletion of the transcription factor STAT5 from neurons (Stat5NKO) led to obesity. Acupuncture, in turn, reduced body weight and the ratio of epididymal white adipose tissue (Epi-WAT) to body weight, and it also decreased plasma concentrations of glucose, triglyceride, and cholesterol. In addition, EA increased cold endurance of Stat5NKO obese mice. EA reversed altered gene expressions in the hypothalamus and Epi-WAT, especially in the hypothalamus in Stat5NKO obese mice. This study provides, for the first time, insight into genomic networks of obesity and their modulation by electro-acupuncture, which in turn reveals potential mechanisms that explain acupuncture-induced weight-loss.
