Background: Postoperative gastrointestinal dysfunction (PGD) is one of the most common complications among patients who have undergone thoracic surgery. Acupuncture has long been used in traditional Chinese medicine to treat gastrointestinal diseases and has shown benefit as an alternative therapy for the management of digestive ailments. This study aimed to explore the therapeutic effectiveness of acupuncture as a means to aid postoperative recovery of gastrointestinal function in patients undergoing thoracoscopic surgery.

Methods: In total, 112 patients aged 18-70 years undergoing thoracoscopic surgery between 15 June 2022 and 30 August 2022 were randomized into two groups. Patients in the acupuncture group (AG) first received acupuncture treatment 4 h after surgery, and treatment was repeated at 24 and 48 h. Patients in the control group (CG) did not receive any acupuncture treatment. Both groups received the same anesthetic protocol. Ultrasound-guided thoracic paravertebral block (TPVB) was performed in the paravertebral spaces between T4 and T5 with administration of 20 mL of 0.33% ropivacaine. All patients received patient-controlled intravenous analgesia (PCIA) after surgery.

Results: Median time to first flatus [interquartile range] in the AG was significantly less than in the CG (23.25 [18.13, 29.75] vs 30.75 [24.13, 45.38] h, p < 0.001). Time to first fluid intake after surgery was significantly less in the AG, as compared with the CG (4 [3, 7] vs 6.5 [4.13, 10.75] h, p = 0.003). Static pain, measured by visual analog scale (VAS) score, was significantly different on the third day after surgery (p = 0.018). Dynamic pain VAS scores were lower in the AG versus CG on the first three postoperative days (p = 0.014, 0.003 and 0.041, respectively).

Conclusion: Addition of acupuncture appeared to improve recovery of postoperative gastrointestinal function and alleviate posteoperative pain in patients undergoing thoracoscopic surgery. Acupuncture may represent a feasible strategy for the prevention of PGD occurrence.

Background/objective: Tobacco use remains the leading cause of preventable death in the United States. The most widely available treatment options to assist patients in smoking cessation are limited by side effects and moderate efficacy at best. Acupuncture may be an effective option for smoking cessation. The goal of this study was to establish the need for and interest in acupuncture therapy to potentially assist with smoking cessation from a patient perspective.

Methods: We conducted a cross-sectional survey study among patients aged 18 years or older whose medical record reported current tobacco use with English as their preferred language. REDCap surveys were administered to patients during office visits and included questions regarding opinions and use of all treatments available for smoking cessation (including acupuncture) as well as perceived barriers to acupuncture treatment.

Results: A total of 57 surveys were distributed, and 42 (74%) were completed. Most patients reported previous attempts at quitting (76%) and had tried a variety of treatments including nicotine replacement (45%), Chantix (varenicline; 23%), Wellbutrin (bupriopion; 19%), "cold turkey" (65%) and hypnosis (3%). No respondents reported having tried acupuncture for smoking cessation.

Conclusion: When comparing treatment options, patients reported more interest in acupuncture than other treatment options with a statistically significant difference in the level of interest between acupuncture and bupropion. All barriers (cost, time and effectiveness) were equally rated on a Likert-type scale with a median of 50 on a 101-point scale.

Background: Acupuncture is a potentially effective non-pharmacological treatment for insomnia.

Objective: We observed the responses of patients with insomnia to acupuncture in routine clinical practice. In addition, we explored patient characteristics that might affect the treatment response to acupuncture for insomnia.

Methods: Medical records of patients with insomnia in a Korean medicine clinic with baseline Insomnia Severity Index (ISI) scores ⩾8 and Pittsburgh Sleep Quality Index (PSQI) scores ⩾5 were reviewed. Acupuncture was applied at ST43, GB41, ST41, SI5, HT3, KI10, HT7 and ST3, for 1-2 months. The ISI and PSQI were measured monthly to assess insomnia severity. The effect of acupuncture over time was analyzed using a multilevel linear model for repeated measures. In addition, logistic regression was used to explore predictors of treatment response.

Results: A total of 91 patients with insomnia aged 59.2 ± 12.5 years (mean ± standard deviation (SD)) (90.1% female) were included in the analysis. After the acupuncture treatment, ISI scores were significantly reduced by -3.75 (95% confidence interval (CI) = -4.99, -2.50) and -4.69 (95% CI = -6.22, -3.16) after the first and second month, respectively. The PSQI global scores also improved, and sleep duration showed a tendency to increase by 0.35 h (95% CI = -0.17, 0.86) after acupuncture treatment. Three cases of mild fatigue were reported. In addition, higher baseline pain/discomfort predicted a greater likelihood of response after acupuncture treatment (odds ratio (OR) = 1.66, 95% CI = 1.10, 2.60).

Conclusion: In a real-world setting, the insomnia of outpatients in a clinic was slightly alleviated after acupuncture treatment. These findings require validation by randomized controlled trials.

Objective: The aim of this study was to explore the role and mechanisms of electroacupuncture (EA) in the regulation of chemokines in endogenous stem cell mobilization and myocardial regeneration after myocardial infarction (MI).

Methods: An MI model was constructed in adult male Sprague-Dawley rats by ligating the left anterior descending coronary artery. After 4 weeks of treatment, echocardiography was used to detect changes in cardiac function, and Masson's trichrome staining was used to detect collagen deposition. In addition, immunofluorescence staining was applied to examine von Willebrand factor (vWF)-positive vessels, the expression of cardiac troponin T (cTnT) and proliferation marker Ki67, and the number of c-kit-positive, C-X-C chemokine receptor type 4 (CXCR4)-positive, and Sca-1-positive endogenous stem cells in the infarcted area. In addition, the expression of stromal cell-derived factor (SDF)-1 and stem cell factor (SCF) was detected.

Results: EA increased the ejection fraction after MI, reduced collagen deposition and cellular apoptosis, and increased the number of blood vessels compared with an untreated model group. EA significantly promoted cellular proliferation, except for myocardial cells, and significantly increased the number of c-kit-, CXCR4- and Sca-1-positive stem cells. Moreover, the expression of SDF-1 and SCF in myocardial tissue in the EA group was significantly higher than that in the (untreated) MI group.

Conclusions: EA appears to promote angiogenesis and reduce collagen deposition, thus improving the cardiac function of rats with MI. The underlying mechanism of action may involve endogenous stem cell mobilization mediated by SDF-1/CXCR4 and SCF/c-kit.

Objective: Insomnia is the most common sleep disorder and is often comorbid with mental and physical diseases. The present study was designed to investigate the hypnotic effect of electroacupuncture (EA) of the cymba concha to stimulate the auricular branch of the vagus nerve (ABVN).

Methods: Mice were intraperitoneally injected with p-chlorophenylalanine (PCPA, 300 mg/kg·d) for 2 days to induce insomnia and subsequently received EA or manual acupuncture (MA) of the cymba concha for 30 min once daily for 5 consecutive days, or no treatment. The phenobarbital-induced sleep test was used to analyze the hypnotic effects and the open field test was used to analyze the locomotor activities and anxiolytic effects of EA/MA of the cymba concha. In addition, the levels of gamma-aminobutyric acid (GABA) and glutamate (Glu) in the hypothalamus and peripheral blood were determined by enzyme-linked immunosorbent assay (ELISA).

Results: PCPA injection significantly decreased sleep duration, increased sleep latency and induced anxiety-like behaviors in mice. In PCPA-insulted mice, EA of the cymba concha improved the sleep disturbance by significantly prolonging sleep duration, while no change in sleep latency was observed. Moreover, EA of the cymba concha improved PCPA-induced anxiety-like behaviors without decreasing locomotor activities in the open field test. EA of the cymba concha increased the level of GABA in the hypothalamus and peripheral blood, while Glu concentrations remained unchanged.

Conclusion: These findings indicate that EA of the region innervated by the ABVN upregulates GABA levels in the hypothalamus and ameliorates the symptoms of insomnia and anxiety, suggesting that EA of the cymba concha might have potential value as an intervention for insomnia.
