Moxibustion therapy for chronic spontaneous urticaria: A protocol for systematic review and meta-analysis

Acupuncture combined with pricking and cupping therapy is effective in patients with chronic spontaneous urticaria

OBJECTIVE

To determine the effects of acupuncture combined with pricking and cupping therapy on the balance of Th1/Th2 cytokines in patients with chronic spontaneous urticaria (CSU).

METHODS

The medical records of 75 patients with CSU treated in The First Affiliated Hospital of Hebei College of Traditional Chinese Medicine from January 10, 2021 to January 10, 2022 were collected and analyzed retrospectively. Among them, 35 patients treated with traditional therapy were assigned to a control group, and 40 patients treated with acupuncture combined with pricking and cupping therapy to an observation group. The clinical efficacy and adverse reactions in the two groups were compared after therapy. The two groups were also compared in terms of the levels of immunoglobulin (Ig)-E, interleukin (IL)-4 and interferon-γ (INF-γ) before and after therapy. In addition, the visual analogue scale (VAS) for pruritus was adopted for recording the pruritus degree of patients before and after therapy. The Dermatology Quality of Life Index (DLQI) was adopted to compare the quality of life between the two groups before and after therapy. The Hamilton anxiety scale (HAMA) and Hamilton depression rating scale (HAMD) were adopted for comparison of the anxiety and depression between the two groups before and after therapy. Moreover, the Pittsburgh sleep quality index (PSQI) was used to compare sleep quality between the two groups before and after therapy.

RESULTS

The control group showed a significantly lower total response rate than the observation group (P<0.05). Compared with the control group, the observation group showed significantly lower levels of IgE and IL-4, and a higher IFN-γ level and had significantly lower pruritus-VAS, DLQI, HAMA, HAMD and PSQI scores (P<0.05). Additionally, the two groups were not greatly different in adverse reactions (nausea, sleepiness, ecchymosis and dizziness) (P>0.05).

CONCLUSION

Acupuncture combined with pricking and cupping therapy is highly effective in CSU, because it can significantly alleviate the symptoms as well as negative emotions, and improve the quality of life, sleep quality and the balance of Th1/Th2 cytokine in patients.

Chemical Fingerprint Profiles and Pharmacodynamic Investigation for Quality Evaluation of Moxa Smoke by UHPLC in a Rat Model of Superficial Infection

Introduction

Moxibustion, a traditional Chinese medicine technique, involves the use of moxa smoke from Folium Artemisia argyi to treat various disorders, especially superficial infections. However, there is a higher health risk for people exposed to high levels of moxa smoke for extended durations. Here, we report the first ultra-high-performance liquid chromatography (UHPLC) fingerprint profiles and pharmacodynamic evaluation of moxa smoke, as well as evaluation of its aqueous solution on a rat model of superficial infection.

Methods

A novel method for moxa smoke fingerprint profiling was developed using UHPLC under characteristic wavelength. Chromatographic peaks were further analyzed by ultra-high-performance liquid chromatography quadrupole-time-of-flight mass spectrometry (UHPLC-QTOF/MS). 12 sample batches obtained from various Chinese provinces were then analyzed using similarity evaluation, clustering analysis, and principal component analysis. The pharmacodynamics of moxa smoke and moxa aqueous solution were investigated on a rat model of acute skin wound infection.

Results

UHPLC fingerprint profiles of 12 batches of moxa smoke were generated at 270 nm wavelength and 21 chromatographic peaks extracted as common peaks. Similarity between the 12 batches ranged from 0.341 to 0.982. Based on cluster analysis, the 12 batches of moxa smoke samples were clustered into five groups. Principal component analysis showed that the cumulative contribution of the three principal components reached 90.17%. Eigenvalues of the first, second, and third principal components were 10.794, 6.504, and 1.638, respectively. The corresponding variance contribution rates were 51.40%, 30.97%, and 7.80%, respectively. Pharmacological analysis found that wound healing was slow in the model group relative to the mupirocin ointment, moxa smoke, and aqueous moxa smoke solution groups. Histological analysis revealed markedly reduced tissue inflammation in rats treated with moxa smoke or its aqueous solution.

Conclusions

Moxa smoke and its aqueous solution significantly promote wound healing upon superficial infection. A novel quality control method for moxa smoke was established and evaluated for the first time. As its main effects are unchanged, the transformation of moxa smoke into aqueous moxa smoke improves safety and is a simple and controllable process.
