[ABSTRACT]OBJECTIVETo investigate the phoenix roebelenii pollen as the allergen of allergic rhinitis in Hainan Province and provide guidance for prevention and treatment of allergic rhinitits.METHODSA total of 2054 patients with allergic rhinitis were tested with the allergen of phoenix roebelenii pollen by skin prick test, and then choose 30 positive cases to give the nasal mucosa provocation test. RESULTSThe total positive rate of allergen of phoenix roebelenii pollen by skin prick test was 67.38% (1384/2054). The 30 cases with positive skin prick test were all positive in nasal mucosa provocation test and the cases in control group were all negative.CONCLUSIONPhoenix roebelenii pollen is an important allergen in Hainan Province. There is a correlation between skin prick test and nasal mucosa provocation test. The allergen skin prick test can provide clue for the patients to avoid the pathogenic allergens and for the specific immunotherapy.

Objective:To test the validity and reliability of the Chinese version of the Cyberbullying Bystand-er Scale(CBS)in Chinese college students.Methods:Totally 722 college students were randomly divided into sample 1(n=356)and sample 2(n=366).Exploratory factor analysis was performed on sample 1,and confirma-tory factor analysis,criterion validity,and internal consistency reliability were performed on sample 2.The criterion validity was tested with the Short Form of Moral Disengagement Scale(MDS).Thirty-seven students of sample 2 were randomly selected and retested 2 week later.Results:The Chinese version of CBS contained 6 distinct factors(40 items),named passive outsider online,defender of the cybervictim online,reinforcer of the cyberbully online,passive face-to-face outsider,face to face defender of the cybervictim,face-to-face reinforcer of the cyberbully.The results of confirmatory factor analysis confirmed that the fitting index of the six-factor modelis good(x2/df=2.83,CFI=0.90,TLI=0.89,RMSEA=0.07,SRMR=0.06).The scores of passive outsider online,reinforcer of the cyberbully online,passive face-to-face outsider and face-to-face reinforcer of the cyberbully were positively correla-ted with the moral disengagement(ICC=0.11-0.28,Ps＜0.05).The internal consistency reliabilities of the scale were from 0.89 to 0.96,the retest reliabilities(ICC)of the scale were between 0.75 to 0.89.Conclusion:The Chinese version of the Cyberbullying Bystander Scale(CBS)shows good validity and reliability in Chinese college students.
