Allergic rhinitis affects approximately 30% of adults and up to 40% of children in industrialized societies. Medicines available for relief of allergic rhinitis symptoms include antihistamines, decongestants, leukotriene inhibitors, topical hormones, and corticosteroids. However, the negative side-effects of antiallergic medicines cause many patients with allergic rhinitis to choose traditional Chinese medical treatments, such as taking Chinese herbs or treatment with acupuncture.
This study assessed the effect of acupuncture for treatment of allergic rhinitis.
Eighteen (18) patients with allergic rhinitis were treated with acupuncture 8 times over a 4-week period, and peripheral blood of these patients was collected at each visit for analysis of gene expression via cDNA microarray. To estimate the therapeutic effect of acupuncture objectively, patients completed the rhinoconjunctivitis quality of life questionnaire (RQLQ) before and after acupuncture therapy.
Based upon patients' response to the RQLQ, acupuncture therapy significantly reduced allergic rhinitis symptoms, including nasal symptoms, non-hay fever symptoms, and sleep and practical problems (associated with daily activities). In addition, expression of interleukin-1 receptor-alpha (IL1R1) in peripheral blood was significantly decreased at 2 hours, 24 hours, and 4 weeks after acupuncture treatment in these patients.
To our knowledge, this is the first report of cDNA microarray analysis of differential gene expression in the peripheral blood of patients with allergic rhinitis before and after acupuncture treatment. Our data suggest that the balance between T-helper 1 and T-helper 2 cell-derived proinflammatory versus anti-inflammatory cytokines might be improved by acupuncture treatment.

    • "Allergic rhinitis occurs when an allergen is inhaled and generates an immune response in an individual. Its symptoms can be reduced by acupuncture treatment at the EX-HN3, LI4, LI20, and ST36 acupoints [56]. The effectiveness of the treatment could be accounted for by modulation of pro- and anti-inflammatory genes observed through microarray analyses of blood samples. "

    ABSTRACT: Meridians, acupoints, and Chinese herbs are important components of traditional Chinese medicine (TCM). They have been used for disease treatment and prevention and as alternative and complementary therapies. Systems biology integrates omics data, such as transcriptional, proteomic, and metabolomics data, in order to obtain a more global and complete picture of biological activity. To further understand the existence and functions of the three components above, we reviewed relevant research in the systems biology literature and found many recent studies that indicate the value of acupuncture and Chinese herbs. Acupuncture is useful in pain moderation and relieves various symptoms arising from acute spinal cord injury and acute ischemic stroke. Moreover, Chinese herbal extracts have been linked to wound repair, the alleviation of postmenopausal osteoporosis severity, and anti-tumor effects, among others. Different acupoints, variations in treatment duration, and herbal extracts can be used to alleviate various symptoms and conditions and to regulate biological pathways by altering gene and protein expression. Our paper demonstrates how systems biology has helped to establish a platform for investigating the efficacy of TCM in treating different diseases and improving treatment strategies.

    • "Both proinflammatory and inflammatory effects have been observed in acupuncture studies [18]. The postacupuncture sequential change of peripheral blood leukocyte subpopulation and cytokines reveals immuneboosting effects [19] [20]. Based on the previous findings, we hypothesize that acupuncture has the potential to correct CNS injury-induced immunodepression and reduce the infectious complications of stroke patients. "

    ABSTRACT: To reduce the health care burden of strokes, the Taiwan Department of Health launched the Pilot Scheme of the Health Policy in Stroke Adjuvant Acupuncture Therapy (HPSAAT) in 2006. This cross-sectional, hospital-based, match-controlled study at Chang Gung Memorial Hospital-Kaohsiung Medical Center during 2006∼2008 retrospectively evaluated the clinical characteristics of acute and subacute ischemic stroke patients who electively joined the HPSAAT. The study also evaluated the safety and clinical benefits of adjuvant acupuncture in treating acute and subacute ischemic stroke patients. Twenty-six HPSAAT participants and 52 age-sex matched random controls were enrolled. The stroke baseline of the HPSAAT participants was more severe than the non-HPSAAT controls. Although the stroke severity closely correlates to mortality and comorbidity, this study noted no significant complications in the HPSAAT participants during the acupuncture treatment course. Adjuvant acupuncture was considered safe at the acute and subacute stages of ischemic stroke. Due to uneven baseline severity, the clinical benefits in reducing neurological deficits and functional recovery were not concluded in this study.

    • "Several clinical studies have indicated that acupuncture or EA treatment is beneficial for allergic disorders, such as asthma, chronic urticaria and allergic rhinitis (Biernacki and Peake, 1998, Chen and Yu, 1998; Jianli, 2006; Ng et al., 2004; Shiue et al., 2008). In general view, hyperproduction of IgE, in which IL-4, the key Th2-specific cytokine, is mainly involved, promotes the development of those allergic disorders (Maggie, 1998; Woodfolk, 2006). "

    ABSTRACT: Acupuncture is probably the most popular alternative therapy practiced in the United States, Europe and many Asian countries. It has been applied clinically for more than 5 thousand years according to the ancient oriental medical theory. A great deal of acupuncture research has been achieved, with particular efforts toward understanding the pain control effects. In addition to the analgesic effect of acupuncture, an increasing number of studies have demonstrated that acupuncture treatment can control autonomic nerve system functions such as blood pressure regulation, sphincter Oddi relaxation, and immune modulation. Although only a limited number of controlled studies have assessed the efficacy of acupuncture, increasing clinical evidences support that EA treatment is effective for various immunological diseases including allergic disorders, infections, autoimmune diseases and immunodifficiency-syndromes. This review will address the mechanism of acupuncture in modulating various immune responses and the relationship between acupuncture mediated immune regulation and neurological involvement.
