ABSTRACT
Objective:To affirm the importance of clinical trial kick-off meeting and improve the meeting quality.Methods:According to the literature review of latest laws and regulations, combined with working experiences in clinical trial management, this article tried to identify possible problems that might occur before, during and after the kick-off meeting, analyze how to better manage the kick-off meeting, and propose suggestions for possible solutions.Results:Newly approved clinical trial institutions may face challenges such as lack of training, unclear responsibilities, lack of attention to quality control of professional department and post-meeting management. Thus, a series of suggestions were proposed, including more substantial communication and tailored training should be in place before the kick-off meeting, responsibilities for each stakeholder should be clarified during the meeting with specific concern of the professional quality control, in addition, meeting minutes and related materials should be well documented after the meeting.Conclusions:Clinical trial kick-off meeting is crucial that clinical trials institutions should pay more attention and work for better administration of such meetings.
ABSTRACT
OBJECTIVE@#To observe the curative effect of Jieminqufeng decoction to the rats of allergic rhinitis and study the mechanism by which it treats allergic rhinitis.@*METHOD@#Forty wistar rats were divided into 4 groups at random. There are Jieminqufeng decoction group, cetirizine group, model control group and normal control group. The rats of allergic rhinitis were established with ovalbumin. We surveyed the behavioral changes of rats, searched eosinophilic granulocytes in the nasal secretion, detected the contents of cAMP and cGMP in the blood plasma and nasal mucosa.@*RESULT@#The model control group had typical symptoms of allergic rhinitis and the eosinophilic granulocytes could be found more frequently. The contents of cAMP and cAMP/cGMP rose in the blood plasma and nasal mucosa (P < 0.01). However, the changes of jieminqufeng decoction group were small.@*CONCLUSION@#The jieminqufeng decoction is an effective drug to allergic rhinitis. Its possible mechanism is that it changes the contents of cAMP and cGMP, lessens inflammatory reaction and blocks up the allergy.

OBJECTIVE To observe the curative effect of Jieminqufeng decoction to the rats with allergic rhinitis. METHODS Fourty Wistar rats were randomly divided into 4 groups. There were Jieminqufeng decoction group (A),cetirizine group (B),model control group(C) and normal control group (D). The rats with allergic rhinitis were established with ovalbumin. The behavioral changes of the rats were observed. The histological and cellular morphological changes were studied with light microscope and transmission electron microscope. RESULTS The model control (C) group had typical symptoms of allergic rhinitis. By light microscope and transmission electron microscope,a lot of eosinophilic granulocytes were found in nasal mucosa. The mucosal cells were lost or destroyed. However,the histological and cellular morphological changes of nasal mucosa in Group A,B were similar to that in Group D. CONCLUSION The Jieminqufeng decoction is an effective drug to treatment of allergic rhinitis. It can decrease the aggregation and activation of eosinophilic granulocytes,lessen inflammatory reaction and block up the allergy.
