RESUMO
OBJECTIVE:To systematically evaluate therapeutic efficacy and safety of Yupingfeng powder in adjavant therapy of allergic rhinitis,and to provide evidence-based reference for clinical treatment. METHODS:Retrieved from Wanfang database,VIP,CJFD,CBM,Cochrane Library,EMBase and PubMed,RCTs about Yupingfeng powder combined with chemical medicine (trial group)vs. chemical medicine alone in the treatment of allergic rhinitis were collected. Meta-analysis was conducted by using Rev Man 5.2 statistical software after data extraction and quality evaluation according to Cochrane system evaluation method 5.1.0. RESULTS:A total of 15 RCTs were included,invovling 1366 patients. The results of Meta analysis showed that response rate [OR=3.95,95%CI(2.80,5.58),P<0.001],recurrence rate [OR=0.37,95%CI(0.22,0.63),P<0.001] and the incidence of ADR [OR=0.15,95%CI(0.06,0.35),P<0.001] in trial group were significantly higher than control group,with statistical significance. CONCLUSIONS:Yupingfeng powder in adjuvant therapy of allergic rhinitis show good therapeutic efficacy and can reduce recur-rence rate with good safety.
RESUMO
OBJECTIVE@#To investigate whether the inflammation response and K(ATP) channel damage happened because of acute injury after functional electrical stimuli (FES) act on the recurrent laryngeal nerve (RLN).@*METHOD@#Thirty rabbits were divided into 3 groups by 10 rabbits for each group. The unilateral RNL were stimulated by FES with cuff electrode in first group. There was electrode on the RNL without FES in second group. The third group was normal control. The electrical generator and isolation unit provide electrical stimulation to the RLN at 50 Hz, with 4 mA current, for 2ms pulse duration. The total train duration was 5 seconds (2 seconds on; 3 seconds off). The RLN were collected in 1 hour after 3 hours electrical stimuli. We measured mRNA expression of injury acute response inflammation cytokine IL-10, TGF-beta1, TNF-alpha and K(ATP) Subunit protein Kir6.1, Kir6.2, SUR2AB, using real-time reverse transcribed-polymerase chain reaction. PCR products were verified by electrophoresis in agarose gels. We investigated the vocal synchronic adductive movement with RLN FES by endoscopy. We investigated the nerve local RNL morphological burn. Data were analyzed with the One-way ANOVA analysis of SPSS version 13.0 for Windows.@*RESULT@#There were no significance difference among three groups in mRNA expression of inflammation cytokines IL-10, TGF-beta1, TNF-alpha and K(ATP) channel protein Kir6.1, Kir6., SUR2AB. We did not find the nerve morphological burn in all rabbits RLN. The vocal synchronic adductive movement were normal during stimuli time.@*CONCLUSION@#The short duration functional electrical stimuli do not cause mRNA expression change of K(ATP) channel and acute inflammation cytokine in recurrent laryngeal nerve.
