Objective To investigate the effect of Biyankang Tablets on quality of life and recurrence rate in patients with chronic rhinosinusitis after functional endoscopic sinus surgery (FESS). Methods A total of 78 patients with chronic rhinosinusitis treated in our hospital during October 2014 to November 2016 were selected, and they were randomly divided into the control group and the traditional Chinese medicine (TCM) group according to the order of admission, with 39 cases in each group. Both groups were treated with FESS, and the TCM group was additionally treated with Biyankang Tablets. The clinical efficacy, inflammatory factors [interleukin-4 (IL-4), interleukin-8 (IL-8)], the prognosis [visual analogue scale (VAS) score of rhinosinusitis and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30)], drug safety and recurrence rates in the two groups were observed. Results After treatment, the total effective rate of treatment in TCM group was significantly higher than that in the control group (89.74% vs 71.79%) (χ2=4.044, P<0.05). After treatment, IL-4, IL-8 and VAS scores in the two groups were significantly decreased, and the scores of EORTC and QLQ-C30 were significantly increased, and the changes of scores in TCM group after treatment were more significant than those in the control group (P<0.05). After treatment, there was no significant difference in the incidence of adverse reactions between the two groups, and the recurrence rate in TCM group was significantly lower than that in the control group in 1 year after treatment (P<0.05). Conclusion TCM Biyankang Tablets is significantly effective in the treatment of patients with chronic rhinosinusitis after FESS. It can significantly inhibit the expression of inflammatory factors, effectively improve the prognosis and quality of life, and significantly reduce the recurrence rate.

Objective This study investigates the effect of collectivism-individualism on parenting goals of middle school students' parents. Methods COLINDEX and Kohn's Parental Values Survey were used. 378 parents participated in the study. Results Fathers had higher score(3.23±0.73) on individualism than do mothers (3.05±0.44,F(1,359)=5.25,P <0.05);and highly educated (college or above) parents had higher scores(4.00±0.86) than do those with less education(for senior high school:3.91±0.81; junior high school or below:3.83±0.97,F(2,363)=4.72,P <0.01). Regression analysis indicated that collectivism had significant effects on goals of "take responsibilities and adapt to environment" ( P <0.01) and "conform to norm and obey parent" ( P <0.01). Both collectivism and individualism had significant effects on goal of "explore and be enterprising" ( P <0.05;P <0.01). Conclusion Parents with high collectivistic value expected their children to assume responsibilities,to adapt to the society,to adhere to norms and to obey authority. However,parents with high individualistic value encouraged their children to be independent and enterprising.

Objective To explore the construct validity of collectivism and individualism scale( COLINDEX) and the reliability and construct validity of its Chinese revision;and to study the development of middle school students' value. Methods The revised scale was used and 5875 middle school students were tested. Resuits Two-factor model of COLENDEX was not substantiated by data,while three factors were abstracted by EFA and confirmed subsequently by CFA. Four factors were abstracted from the Chinese revision of COLINDEX, and four-factor model was confirmed. The Cronbach's alpha coefficients of the total scale (0.90) and four sub-scales (0.84,0.76,0.84 and 0.74 )were all significantly high. MANOVA was performed to detect gender and grade differences of means in the four dimensions of the revised scale. The main effects of gender and grade reached the significant level; however, interaction between them did not. Conclusion Collectivism and individualism, two dimensions of Chinese middle school students' value, were not mutually independent. The revised version of COLINDEX was qualified to be used in further research. The grades on collectivistic items of middle school students were higher than those on individualistic items.
