[Research progress of neuroendocrine mechanism of acupuncture for dyspnea].

Zhen Ci Yan Jiu 2022 Jun;47(6):559-64

Department of Integrated Traditional Chinese and Western Medicine, West China Hospital, Sichuan University, Chengdu 610041.

The paper reviewed the relevant studies on dyspnea treated with acupuncture over the past 20 years, as well as the underlying neuroendocrine mechanism from the perspective of central and peripheral vagus nerves, neurotransmitter, respiratory muscle function and anti-depression-anxiety function. It revealed that the central response area was regulated by acupuncture in treatment of dyspnea, which is similar to the area affected in acupuncture analgesia. Additionally, acupuncture generates its therapeutic effects on dyspnea through promoting the release of endogenous opioid peptides and the regulation of autonomic nerve, amygdale and hypothalamic-pituitary-adrenal axis.

Acupuncture for Patients With Chronic Tension-Type Headache: A Randomized Controlled Trial.

Neurology 2022 Jun 22. Epub 2022 Jun 22.

The Third Hospital/Acupuncture and Tuina School, Chengdu University of Traditional Chinese Medicine, Chengdu, China

Background And Objectives: Whether acupuncture is effective for chronic tension-type headache (CTTH) is inconclusive. We aimed to examine the effectiveness of acupuncture with a follow-up period of 32 weeks.

Methods: We conducted a randomized controlled trial, and 218 participants who were diagnosed with CTTH were recruited from June 2017 to September 2020. The participants in the intervention group received 20 sessions of true acupuncture (TA group) over 8 weeks. The acupuncture treatments were standardized across participants, and each acupuncture site was needled to achieve sensation. Each treatment session lasted 30 minutes. The participants in the control group received the same sessions and treatment frequency of superficial acupuncture (SA group)-defined as a type of sham control by avoiding sensation at each acupuncture site. The main outcome was the responder rate at 16 weeks after randomization (week 16) and was followed up at week 32. A responder was defined as a participant who reported at least a 50% reduction in the monthly number of headache days (MHDs).

Results: Our study included 218 participants (mean age: 43.1 years, mean disease duration: 130 months, MHDs: 21.5 days). The responder rate was 68.2% in the TA group (n=110) versus 48.1% in the SA group (n=108) at week 16 (odds ratio, 2.65; 95%CI, 1.5 to 4.77; p<0.001); and it was 68.2% in the TA group versus 50% in the SA group at week 32 (odds ratio, 2.4; 95%CI, 1.36 to 4.3; p<0.001). The reduction in MHDs was 13.1±9.8 days in the TA group versus 8.8±9.6 days in the SA group at week 16 (mean difference, 4.3 days; 95%CI, 2.0 to 6.5; p<0.001), and the reduction was 14±10.5 days in the TA group versus 9.5±9.3 days in the SA group at week 32 (mean difference, 4.5 days; 95%CI, 2.1 to 6.8; p<0.001). Four mild adverse events were reported; three in the TA group versus one in the SA group.

Conclusion: The 8-week TA treatment was effective for the prophylaxis of CTTH. Further studies might focus on the cost-effectiveness of the treatment.

Trial: Registration : NCT03133884 ( CLASSIFICATION OF EVIDENCE: This study provides Class I evidence that acupuncture (achieving deqi sensation) reduces mean headache days (per month) in patients with chronic tension-type headache.

Altered Resting Brain Functions in Patients With Irritable Bowel Syndrome: A Systematic Review.

Front Hum Neurosci 2022 29;16:851586. Epub 2022 Apr 29.

Acupuncture and Tuina School, Chengdu University of Traditional Chinese Medicine, Chengdu, China.

Background: The neural activity of irritable bowel syndrome (IBS) patients in the resting state without any intervention has not been systematically studied. The purpose of this study was to compare the resting-state brain functions of IBS patients with healthy controls (HCs).

Methods: The published neuroimage studies were obtained from electronic databases including PubMed, EMBASE, PsycINFO, Web of Science Core, CNKI Database, Wanfang Database, VIP Database, and CBMdisc. Search dates were from inception to March 14th, 2022. The studies were identified by the preidentified inclusion and exclusion criteria. Two independent reviewers compiled the studies and evaluated them for quality and bias.

Results: Altogether 22 fMRI studies were included in this review. The risk of bias of the included studies was generally low. The findings indicated that in IBS patients, increased or decreased brain areas were mostly associated with visceral sensations, emotional processing, and pain processing. According to brain network research, IBS may exhibit anomalies in the DMN, CEN, and emotional arousal networks. The fluctuations in emotion (anxiety, sadness) and symptoms in IBS patients were associated with alterations in the relevant brain regions.

Conclusion: This study draws a preliminary conclusion that there are insufficient data to accurately distinguish the different neurological features of IBS in the resting state. Additional high-quality research undertaken by diverse geographic regions and teams is required to reach reliable results regarding resting-state changed brain regions in IBS.

Electroacupuncture Alleviates Visceral Hypersensitivity in IBS-D Rats by Inhibiting EGCs Activity through Regulating BDNF/TrkB Signaling Pathway.

Evid Based Complement Alternat Med 2022 14;2022:2497430. Epub 2022 Feb 14.

Acupuncture and Tuina School of Chengdu University of Traditional Chinese Medicine, Chengdu, Sichuan 610075, China.

Objective: To determine whether electroacupuncture (EA) could alleviate visceral hypersensitivity in diarrhea-predominant irritable bowel syndrome (IBS-D) rats by inhibiting EGCs activity via the BDNF/TrkB signaling pathway.

Methods: Sprague Dawley rats were randomly divided to a control group ( = 8) and a model preparation group ( = 32), which received Senna solution by gavage and CUMS (chronic unpredictable mild stress) for 14 consecutive days and was further divided to a Model group, an EA group (only electroacupuncture), an EA + TrkB agonist group (electroacupuncture and TrkB), and an EA + DMSO group (electroacupuncture and DMSO,  = 8 for each). Rats in the three EA groups were acupunctured at ST25, ST36, and LR3 for 20 min every day for 14 days. Abdominal withdrawal reflex (AWR) was used to quantify visceral sensitivity; reverse transcription polymerase chain reaction (RT-PCR) and double immunofluorescent staining were used to detect the colocalized expression of GFAP/BDNF and GFAP/TrkB. Western Blot (WB) was used to detect the expression of PLC and SP in the colon. Flow cytometry was used to detect the expression of Ca.

Results: EA effectively alleviated visceral hypersensitivity in IBS-D rats ( < 0.05). Compared to the control group, the expression of BDNF, TrkB, PLC, SP, and Ca and the colocalized expression of GFAP/BDNF and GFAP/TrkB increased in the Model group ( < 0.05), while all these parameters decreased in the EA group following EA intervention ( < 0.05). In addition, no significant difference was found between the EA + TrkB agonist group and the control group ( > 0.05).

Conclusions: EA alleviates visceral hypersensitivity of IBS-D rats possibly by inhibiting the activity of EGCs through the BDNF/TrkB-PLC-Ca signaling pathway in the colon.

Cupping therapy for patients with chronic urticaria: A systematic review and meta-analysis.

J Integr Med 2020 Jul 28;18(4):303-312. Epub 2020 May 28.

Graduate School, Chengdu University of Traditional Chinese Medicine, Chengdu 610000, Sichuan Province, China. Electronic address:

Background: Chronic urticaria (CU) is a common skin disease, which has a negative effect on quality of life. Current treatments do not fully control the symptoms of urticaria for many CU patients, thus effective and safe treatments for CU are still needed.

Objective: This review aims to evaluate the effectiveness and safety of cupping therapy in patients with CU.

Search Strategy: The search strategy looked for the presence of related keywords, such as "chronic urticaria" and "cupping therapy," in the title and abstract of research articles indexed in major databases. Randomized controlled trials (RCTs) were selected after querying nine electronic databases from their inception to May 2019 with the above search terms.

Inclusion Criteria: RCTs were included if they recruited patients with CU who were intervened with dry or wet cupping. Publications could be written in Chinese or English.

Data Extraction And Analysis: Data were extracted, and the studies were assessed for the quality of their methodological design and risk of bias. Meta-analyses of the RCT data were conducted to assess the total effective rate of the treatment as the primary outcome. Skin disease quality of life index score, recurrence rate, and adverse events were assessed as secondary outcomes. Subgroup analyses were conducted based on different interventions.

Results: Thirteen comparisons from 12 RCTs involving 842 participants were included. There were no significant differences between wet cupping and medications in total effective rate (n = 372; risk ratio [RR] = 1.10, 95% confidence interval [CI] 0.97 to 1.25; P = 0.14) or recurrence rate (n = 240; RR = 0.56, 95% CI 0.23 to 1.36; P = 0.20). Cupping therapy, in combination with antihistamine treatment was more efficacious than antihistamines alone, with a greater total effective rate (n = 342; RR = 1.18, 95% CI 1.01 to 1.39; P = 0.03) and lower recurrence rate (n = 342; RR = 0.52, 95% CI 0.32 to 0.84; P = 0.007). Cupping therapy combined with acupuncture was more effective than acupuncture alone (n = 156; RR = 1.25, 95% CI 1.07 to 1.46; P = 0.006). No serious adverse events were reported.

Conclusion: Wet cupping may be as effective as treatment with antihistamines. When cupping therapy is used as an adjuvant therapy to antihistamines or acupuncture, it may enhance the efficacy. Results drawn from these studies should be interpreted with caution and applied with care to clinical practice, because of the poor quality among the studies that were reviewed.

Methodological and reporting quality evaluation of systematic reviews on acupuncture in women with polycystic ovarian syndrome: A systematic review.

Complement Ther Clin Pract 2018 Nov 11;33:197-203. Epub 2018 Oct 11.

Graduate School, Chengdu University of Traditional Chinese Medicine, Chengdu, Sichuan, China. Electronic address:

Purpose: To evaluate the methodological and reporting quality of systematic reviews (SRs) on acupuncture treatment for women with polycystic ovarian syndrome (PCOS).

Methods: A comprehensive search on multiple databases was performed. Methodological and reporting quality of reviews were assessed by revised assessment of multiple systematic reviews (AMSTAR 2) and preferred reporting items for SRs and meta-analyses (PRISMA), respectively.

Results: Ten SRs were included. Among the SRs using AMSTAR 2, two achieved a good overall rating (percentage of items with "yes" > 50%) and severe limitation existed in eleven items (percentage of items with "yes" < 50%). Among the SRs using PRISMA, six reviews achieved a good overall rating (percentage of items with "yes" > 50%), while twelve items were poorly reported (percentage of items with "yes" < 50%).

Conclusion: There were many deficiencies in the methodological and reporting quality of SRs assessing acupuncture in women with PCOS.
