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.

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 investigate the manifestations of CT and MRI images of paranasal sinuses sarcoma, improve the accuracy of diagnosis. Methods Make retrospective analysis of our hospital from January 2008 to January 2014,36 patients with pathologically confirmed nasal sinuses sarcoma in patients with CT and MRI imaging data, to explore the value of imaging diagnosis. Results The MRI sarcoma typically presents with slight long T1 and slight long T2 signal,enhanced moderately enhanced. 36 cases of lesions center located in the sphenoid region, in maxillary sinus in 6 cas-es. The CT diagnosis of paranasal sinuses sarcoma of the lesion was a total of 27 cases(75.00%),the MRI can provide the diagnosis of paranasal sinuses sarcoma in 35 cases(97.22%),two methods had significant difference (χ2=7.43,P<0.05). Conclusion CT can effectively show the sinus bone destruction, MRI could clearly display the lesion's extent,the combination of image can provide more comprehensive information for the diagnosis and treatment of the Sinus.

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.

As the search for effective treatments for COVID-19 continues, the high mortality rate among critically ill patients in Intensive Care Units (ICU) presents a profound challenge. This study explores the potential benefits of traditional Chinese medicine (TCM) as a supplementary treatment for severe COVID-19. A total of 110 critically ill COVID-19 patients at the Intensive Care Unit (ICU) of Vulcan Hill Hospital between Feb., 2020, and April, 2020 (Wuhan, China) participated in this observational study. All patients received standard supportive care protocols, with a subset of 81 also receiving TCM as an adjunct treatment. Clinical characteristics during the treatment period and the clinical outcome of each patient were closely monitored and analysed. Our findings indicated that the TCM group exhibited a significantly lower mortality rate compared with the non-TCM group (16 of 81 vs 24 of 29; 0.3 vs 2.3 person/month). In the adjusted Cox proportional hazards models, TCM treatment was associated with improved survival odds (P < 0.001). Furthermore, the analysis also revealed that TCM treatment could partially mitigate inflammatory responses, as evidenced by the reduced levels of proinflammatory cytokines, and contribute to the recovery of multiple organic functions, thereby potentially increasing the survival rate of critically ill COVID-19 patients.
