OBJECTIVE: To observe the effect of acupoint sticking on clinical symptoms and life quality in patients with bronchial asthma. METHODS: Multicenter randomized double-blind clinical trial was done, one hundred and eighty-eight cases were divided into a medication acupoint sticking group (125 cases) and a placebo group (63 cases). Dazhui (GV 14), Feishu (BL 13), Tiantu (CV 22), etc. were selected in both groups. The medication cakes were made of grinding pepper, brassica alba seeds, asarum, etc. into fine powder mixed with ginger oil and ginger juice, applied on acupoints in the acupoint sticking group. While another compound cakes made of powder of red rice, black rice, maize mixed with small amount of ginger juice, were used in the placebo group. Asthma Quality of Life Questionnaire(AQLQ), symptom scores during the day and night, scores of self effect, and the value of lung function were observed. RESULTS: The value of daily behavior and environmental factors of AQLQ, total scores of AQLQ, daytime symptoms and scores of self effect in the medication acupoint sticking group, were significantly improved compared to those of placebo group (all P<0.05). The lung function of forced expiratory volume in one second (FEV1) and the percentage of forced expiratory volume in one second in predicted value (FEV1/FVC) had no significant diffrence between two groups (both P>0.05). CONCLUSION: The acupoint sticking therapy can significantly improve clinical symptoms of patients with bronchial asthma, and can improve life quality of the patients.

Black cumin seed, Nigella sativa L., and its oils have traditionally been used for the treatment of asthma and other inflammatory diseases. Thymoquinone (TQ) has been proposed to be one of the major active components of the drug. Since leukotrienes (LTs) are important mediators in asthma and inflammatory processes, the effects of TQ on leukotriene formation were studied in human blood cells. TQ provoked a significant concentration-dependent inhibition of both LTC4 and LTB4 formation from endogenous substrate in human granulocyte suspensions with IC50 values of 1.8 and 2.3 microM, respectively, at 15 min. Major inhibitory effect was on the 5-lipoxygenase activity (IC50 3 microM) as evidenced by suppressed conversion of exogenous arachidonic acid into 5-hydroxy eicosatetraenoic acid (5HETE) in sonicated polymorphonuclear cell suspensions. In addition, TQ induced a significant inhibition of LTC4 synthase activity, with an IC50 of 10 microM, as judged by suppressed transformation of exogenous LTA4 into LTC4. In contrast, the drug was without any inhibitory effect on LTA4 hydrolase activity. When exogenous LTA4 was added to intact or sonicated platelet suspensions preincubated with TQ, a similar inhibition of LTC4 synthase activity was observed as in human granulocyte suspensions. The unselective protein kinase inhibitor, staurosporine failed to prevent inhibition of LTC4 synthase activity induced by TQ. The findings demonstrate that TQ potently inhibits the formation of leukotrienes in human blood cells. The inhibitory effect was dose- and time-dependent and was exerted on both 5-lipoxygenase and LTC4 synthase activity.

OBJECTIVES: Bronchial asthma is a chronic inflammatory airways disease. Nutritional intervention is an important tool to decrease the severity of many chronic inflammatory diseases including asthma. The aim of this study is to evaluate the role of omega-3 fatty acids, vitamin C and Zn in children with moderately persistent asthma. PATIENTS AND METHODS: Randomly assigned, placebo-self-controlled 60 children with moderate persistent asthma completed the study, were subjected to alternating phases of supplementation with omega-3 fatty acids, vitamin C and Zn either singly or in combination separated with washout phases. Childhood asthma control test (C-ACT), pulmonary function tests and sputum inflammatory markers were evaluated at the beginning of the study and at the end of each therapeutic phase. RESULTS: There was a significant improvement of C-ACT, pulmonary function tests and sputum inflammatory markers with diet supplementation with omega-3 fatty acids, vitamin C and Zn (p < 0.001*). There was also significant improvement with the combined use of the three supplementations than single use of any one of them (p < 0.001*). CONCLUSION: Diet supplementation with omega-3 fatty acids, Zn and vitamin C significantly improved asthma control test, pulmonary function tests and pulmonary inflammatory markers in children with moderately persistent bronchial asthma either singly or in combination.
