Objective To explore the effect of Shu-mu acupoint catgut embedding (ACE) on appetite in abdominal obesity (AO) patients. Methods This is a secondary analysis of a multicenter, double-blind, randomized controlled trial. Which was conducted in China between July 2018 and June 2022. Eighty AO participants who received Shu-mu ACE intervention were divided into moderate appetite (MA) and strong appetite (SA) subgroups, according to the appetite at baseline. While 79 AO participants who received NACE intervention were also divided into MA and SA subgroups. All participants were given a 12-week actual intervention period and a 4-week follow-up. Appetite was assessed at baseline and after 6, 12 and 16 weeks. Results 71 participants who received Shu-mu ACE and 74 participants who received NACE were included in the final analysis. After the Shu-mu ACE, at 16 weeks, the appetite of the SA subgroup decreased to the same level as the MA subgroup (p > 0.05). All 36 AO participants’ appetite had decreased in the SA subgroup. While in the MA subgroup, 22 AO participants had a decrease in appetite, 7 increased, 4 had no change, and 2 had appetite data missing. During the NACE intervention and follow-up, the appetite of the SA subgroup was always higher than the MA subgroup (p < 0.01). In the SA subgroup, 32 decreased, 4 increased, 5 had no change, and 2 appetite data missing. While in the MA subgroup, 14 decreased, 7 increased, and 10 had no change. Conclusions Catgut embedding at Shu-mu acupoint could regulate the appetite of AO to the normal level, rather than dramatically inhibit the appetite.

BACKGROUND Obesity is an increasing worldwide problem. Previous studies suggested that acupoint catgut embedding (ACE) may be an effective obesity treatment. However, the evidence for the efficacy of ACE in abdominal obesity (AO) remains inadequate due to the paucity of high-quality studies. OBJECTIVE This study aims to investigate the difference in the effectiveness of catgut embedding at acupoints and catgut embedding at non-acupoints in AO patients. METHODS This is a multicenter, double-blind, 16-week randomized controlled trial (RCT). A total of 92 eligible AO participants will be randomly divided into two groups (1:1 allocation ratio). The ACE group will receive catgut embedding at acupoints and the control group will receive catgut embedding at non-acupoints. The intervention will be performed every two weeks for a total of 6 sessions. Follow-up will be performed every two weeks for a total of 2 visits. The primary outcome is waist circumference (WC). Secondary outcomes include body weight (BW), body mass index (BMI), hip circumference (HC), and visual analog scale (VAS) of appetite. RESULTS This trial protocol was approved by the Institutional Review Board in June 2018. The start of recruitment began in August 2019 and is expected to end in September 2023. Upon completion of the trial, we will evaluate the effect of catgut embedding in acupoints or non-acupoints on obesity indicators in patients with AO. For treatment outcomes, an intention-to-treat analysis will be performed. CONCLUSIONS Although studies have been conducted to demonstrate the effectiveness of ACE in the treatment of obesity. However, the evidence for the efficacy of ACE in AO remains insufficient due to the quality of the studies. This rigorous normative randomized controlled trial will verify the effect of catgut embedding in acupoints or non-acupoints for AO. The findings will provide credible evidence as to whether ACE is an effective and durable treatment for AO.

Background Obesity is an increasing problem worldwide. The effective treatments for obesity mainly include diet, physical activity, behavioral intervention, pharmacotherapy, and bariatric surgery, which all have certain limitations. As a specific type of acupuncture therapy, acupoint catgut embedding (ACE) has gained substantial attention in the management of obesity in recent years. Previous studies suggested that ACE may be an effective obesity treatment. However, the evidence for the efficacy of ACE in abdominal obesity (AO) remains inadequate due to the paucity of high-quality studies. Objective This study aims to investigate the difference in the effectiveness of catgut embedding at acupoints and catgut embedding at nonacupoints in patients with AO and to further validate the efficacy and safety of ACE for AO. Methods This is a multicenter, double-blind, 16-week randomized controlled trial. A total of 92 eligible participants with AO will be randomly divided into 2 groups (1:1 allocation ratio). The ACE group will receive catgut embedding at acupoints and the control group will receive catgut embedding at nonacupoints. The intervention will be performed every 2 weeks for a total of 6 sessions. Follow-up will be performed every 2 weeks for a total of 2 visits. The primary outcome is waist circumference. Secondary outcomes include body weight, BMI, hip circumference, and the visual analog scale of appetite. Upon the completion of the trial, we will evaluate the effect of catgut embedding at acupoints or nonacupoints on obesity indicators in patients with AO. For treatment outcomes, an intention-to-treat analysis will be performed. Results The start of recruitment began in August 2019 and is expected to end in September 2023.

Background Suicide is a devastating and major medical and social problem, and effective management of depression with suicidal ideation (DWSI) is of significant importance in reducing suicide rates. Acupuncture has been less studied in DWSI, and its central mechanisms have not been elucidated. This study aims to carry out a clinical trial using multimodal brain imaging techniques to investigate the mechanism of brain network regulation of DWSI by acupuncture. Method A total of 70 patients with DWSI and 30 healthy subjects will be recruited for this study. This trial will include a 1-week baseline phase, a 12-week treatment phase, and a 8-week follow-up phase. Patients in the acupuncture group will receive 36 sessions of acupuncture, 3 times a week for 12 weeks. Patientsin the paroxetine control group will receive paroxetine 10 mg per day (week 1), 20 mg per day (weeks 2); and 30 mg per day (weeks 3-12). The primary outcomes are the mean change in the Hamilton Depression Rating Scale-24 scores and the Beck scale for suicide ideation. The secondary outcomes include the Depression Self-Rating Scale, Clinical Global ImpressionsScale, Asberg Antidepressant side effect scale and World Health Organization Quality of Life Questionaire abbreviated version. Magnetic resonance imaging data will be collected from each participant at baseline and each patient at the end of treatment. Conclusions This study hypothesised that acupuncture therapy could treat DWSI by restoring the pathological center of suicidal ideation in brain. This study will clarify the mechanism of brain network regulation of DWSI by acupuncture. Trial registration number ChiCTR2200059267, registered on April 7, 2022.
