Obesity is a growing chronic health problem worldwide. Studies about acupuncture for obesity treatment are many. But there are some doubts about the effectiveness of acupuncture versus sham acupuncture in treating obesity due to its lack of medical evidence. Therefore, the aim of this study is to assess the efficacy of acupuncture for obesity treatment and provide clinic evidence. Four English databases (PubMed, EMBASE, Web of Science and Cochrane Central Register of Controlled Trials) and four Chinese databases (China National Knowledge Infrastructure, Chinese BioMedical Database, Chinese Scientific Journal Database and Wan-Fang Data) were searched from their receptions to August 2019. Randomized controlled trials (RCTs) using the comparison between acupuncture and sham acupuncture to treat simple obesity were included. The primary outcome of body mass index (BMI) would be used to measure the effect of acupuncture on obesity. According to the trial data extraction form based on the Cochrane Handbook, two reviewers separately extracted the data. Risk of bias of the RCTs was assessed by the Cochrane Risk of Bias Tool. The study included 8 RCTs with 403 patients. When compared with sham acupuncture, acupuncture showed obviously effect in BMI reduction (MD=1.0kg/m2, 95% CI=0.6 to 1.4, P<0.001). There was also significant reduction in body weight (MD=1.85kg, 95%CI=0.82 to 2.88, p<0.001), WC (MD=0.97cm, 95%CI=0.24 to 1.71, p=0.01) and body fat mass percentage (MD=1.01, 95%CI=0.25 to 1.77, p<0.05). However, WHR (MD=0.01, 95%CI=0 to 0.03, p>0.05) was not statistically and significantly different between the acupuncture and control groups. Adverse effects were reported in 3 studies. The review suggests that acupuncture is an effective therapy for simple obesity rather than a placebo effect. This potential benefit needs to be further evaluated by longer-term and more rigorous RCTs.
Rheumatoid arthritis (RA) is a systemic and chronic autoimmune inflammatory disease characterized by severe synovial hyperplasia associated with progressive cartilage degradation. Due to the severe pain and disability caused by RA, effective therapeutic strategies that could simultaneously alleviate the inflammatory response and delay the disease progression are urgently needed. As a major alternative therapy in traditional Chinese medicine, moxibustion has been demonstrated that it could reduce the chronic inflammatory responses of a series of musculoskeletal diseases; however, whether moxibustion has protective effects on RA is still unclear. To investigate the effects of moxibustion on RA, moxibustion was applied to Zusanli (ST36) and Shenshu (BL23) acupoints in a RA rabbit model. HE staining of articular cartilage showed that moxibustion alleviated the cartilage degradation and bone destruction. In addition, moxibustion decreased the osteoclast number in RA rabbits. Real-time PCR revealed that moxibustion decreased the expression of RANKL mRNA while increased the expression of OPG mRNA, indicating a restoration of the balance between osteogenesis and osteoclastogenesis. Taken together, our results indicated that moxibustion had promising antiarthritic effects and could be an useful alternative method in RA therapeutics.
Background. This study aims to systematically evaluate the effect of moxibustion on the level of inflammatory cytokines in animal models with rheumatoid arthritis (RA) and to provide evidence for the clinical application of moxibustion to the treatment of RA and related basic researches. Methods. The databases employed in this study include PubMed, EMBASE, Web of Science, China National Knowledge Infrastructure (CNKI), Chinese Science and Technology Periodical Database (VIP), SinoMed, and Wanfang Data Information Site. The retrieval time was from the establishment of these databases to March 2020. The reviewers made use of the CAMARADES 10-item checklist to evaluate the quality of each included study. The inflammatory cytokines were considered as the outcome measure. The Revman 5.3 software was used to conduct meta-analysis on the outcome indicators of the studies included. Results. A total of 648 articles were retrieved and 18 animal experiments were included in this study. The quality scores of the studies ranged from two to eight with a mean of 5.8. Compared with the effect of the control group, moxibustion reduced the expression of TNF-α (SMD 2.95, 95% CI: 1.99–3.92, P<0.00001), IL-1β (SMD 4.10, 95% CI: 2.37–5.84, P<0.00001), IFN-γ (MD 25, 95% CI: 16.17–33.82, P<0.00001), IL-6 (MD 11.83, 95% CI: 6.22–17.44, P<0.0001), and IL-17 (MD 99.3, 95% CI: 86.83–111.76, P<0.00001). At the same time, the level of IL-2 (SMD 8.89, 95% CI: 0.93–16.86, P=0.03), IL-4 (MD 1.79, 95% CI: 0.26–3.32, P=0.02), and IL-10 (MD 5.93, 95% CI: 1.37–10.49, P=0.01) increased after moxibustion treatment. Asymmetric funnel plots indicated that there was publication bias. Conclusion. The findings of the present review indicate that moxibustion can protect the synovium of joint in animal models with RA by upregulation of the level of anti-inflammatory cytokines and downregulation of the level of proinflammatory cytokines. Moxibustion has the potential to relieve inflammation of RA.
Objective. Rheumatoid arthritis (RA) is an autoimmune disease that starts with inflammation of the synovium. The pain and joint dysfunction caused by RA urgently need an effective treatment to alleviate the inflammatory reaction and delay the progression of the disease. The pathological damage of RA is proposed to associate with the dysfunction of the programmed cell death 1/programmed cell death ligand 1 (PD-1/PD-L1) pathway. Moxibustion, as a main complementary therapy of traditional Chinese medicine (TCM), has been proved effective to reduce chronic inflammatory reaction on RA, but whether the anti-inflammatory effects are mediated by PD-1/PD-L1 pathway is still unclear. Therefore, moxibustion was conducted in the rats with RA to investigate its effect on PD-1/PD-L1. Methods. The rats' right hind paws were injected with Freundʼs complete adjuvant (FCA) to establish the model of RA. Seven days after the injection of FCA, moxibustion therapy was performed on the acupoints of Shenshu (BL23) and Zusanli (ST36) once a day for three weeks. Then, ELISA and immunohistochemical methods were used to analyze the influence of moxibustion on the expression of PD-1/PD-L1. If the moxibustion had an effect on the expression of PD-1/PD-L1-related molecules, we would knock down PD-1 with adenovirus vector. After moxibustion therapy, ELISA and histological analysis were performed to observe the anti-inflammatory effect of moxibustion. Results. The results demonstrated that moxibustion had an effect on the expression of PD-1-related molecules. The results of ELISA manifested that moxibustion decreased the level of IFN-γ and increased the level of IL-4 and IL-10. HE staining revealed that moxibustion alleviated the proliferation of synovial tissue. However, the anti-inflammatory effect and pathological improvement were weakened when PD-1 was blocked. Conclusions. The results indicate that moxibustion affected the expression of PD-1/PD-L1-related molecules and can effectively treat RA damage. The anti-inflammatory effect of moxibustion was weakened when PD-1 was knocked down.
Background Rheumatoid arthritis (RA) is a refractory autoimmune disease characterized by chronic synovitis. Moxibustion is a natural therapy that possesses anti-inflammatory bioactivity. However, the anti-inflammatory mechanism of moxibustion for the treatment of RA has not yet been clarified. Macrophage infiltration is a prominent characteristic in the pathological process of RA synovitis. Objective The aim of the present research is to investigate the effect of moxibustion on the polarization of macrophage. Methods The rats' right hind paws were injected with freundʼs complete adjuvant (FCA) to establish the model of RA. Seven days after the injection of FCA, moxibustion therapy was performed on the acupoints of Shenshu (BL23) and Zusanli (ST36) once a day for three weeks. The Immunofluorescence, Western bolt and Elisa were used to analyze the influence of moxibustion on the expression of STAT1/miR-155/SOCS1 signaling pathway and macrophage's marker. Results We observed that moxibustion decreased the thickness of foot pad and arthritis scores. Moxibustion up-regulated the exression of Tim-3, promoted the polarization of macrophages to M2 type and inhibited the polarization of macrophages to M1 type. Treatment with moxibustion decreased the level of interleukin (IL)-23 and increased the level of IL-4, IL-10 and Argininase (Arg)-1. Moreover, moxibustion blocked the activation of STAT1/miR-155/SOCS1 signaling pathway and promoted the polarization of macrophages to M2 type. Furthermore, when Tim-3 was knocked down, the anti-inflammatory effect of moxibustion was reduced and the effect of regulating macrophage polarization was inhibited. Conclusion moxibustion may regulate the expression of related molecules in the STAT1/miR-155/SOCS1 signaling pathway through Tim-3, promote the polarization of macrophages M2, and exhibit anti-inflammatory effects.
