Modern Clinical Nursing 2016;15(2):34-37
Objective To explore the effect of different infusion speeds on prevention phlebitis caused by lavofloxacin hydrochloride. Methods One hundred and sixty patients treated with intravenous infusion of lavofloxacin hydrochloride were randomized by simple digital table into one observation group and three control groups with 40 in each group. The infusion velocities in the observation group and other three control groups were 61~70 gtt/min, 30~40 gtt/min, 41~50 gtt/min and 51 to 60 gtt/min, respectively. The incurrence rate of phlebitis was compared among the four groups. Results The incidence rate of phlebitis in the observation group was significantly lower than that of the respective control group (all P<0.05). There were no differences among the three control groups in terms of phlebitis rate. Conclusion Intravenous infusion of lavofloxacin hydrochloride at the infusion velocity of 61~70 gtt/min can reduce the incidence of phlebitis.
2.Impact of gender role and gender traits on depression in adolescents
Chinese Journal of Behavioral Medicine and Brain Science 2013;(6):550-552
Objective To study the impact of gender,gender role and gender traits on depression in adolescents.Methods A sample of 1330 middle school students from seven provinces in China completed Beck Depression Inventory (BDI) and Gender Traits Inventory.Results 27.1 percents of participants displayed the symptoms of depression.The mean score of males of BDI was 10.04 ± 8.38 while that of females was 10.33 ± 8.37,indicating that there was no sex differences in depression of adolescents(P=0.535).The participants could be classified into 4 sex role types:masculine,feminine,androgynous and undifferentiated,and the BDI mean score of each type was 9.51 ± 7.66,12.30 ± 8.81,9.14 ± 8.10,10.72 ± 8.66,and significant differences were found among adolescents with different gender roles (P =0.000).BDI scores of the feminine adolescents were the highest among the four gender roles,which were significantly higher than scores of the masculine and androgynous adolescents (P =0.000).Regression analysis indicated that adolescents with more positive masculine traits tended to be less depressive (t =-4.966,P < 0.01) while adolescents with more negative masculine (t =2.574,P < 0.01) or feminine (t =10.566,P < 0.01)traits tended to be more depressive.Conclusion Gender role rather than gender has greater impacts on adolescent depression,and specifically,positive masculine traits represent protective factors for depression.

Chinese Journal of General Surgery 2001;16(2):110-112
Objectiver To establish murine breast precancerous model and evaluate the effect of exogenous estrogen and tamoxifen. Method 50 female Wistar rats were divided into contol group (n=12), the other 38 received low dose carcinogen (DMBA) by gastrogavage, and then divided into DMBA group (common diet,n=8); DMBA+DES group(DES added chow,n=15); and DMBA+TAM group (TAM added chow,n=15). 3 months later, the status of breast hyperplasia, AgNOR and DNA content were measured. Results All indexs in control group and DMBA+TAM group were normal.However,in DMBA group and DMBA+DES group,the breast hyperplasia rate was 75%, 93.3%, AgNOR was 3.71±0.76, 5.60±0.42, DNA was 88.59±7.17, 137.75±3.13 respectively.Compared with control group and DMBA+TAM group, the differences of indexes in DMBA and in DMBA+DES group were significant (P<0.01). Conclusion Low dosage DMBA administered by gastrogavage established breast precancerous model. Exogenous estrogen promotes the development of breast precancerous disease induced by DMBA, while TAM suppresses the canceration.
