Objective In order to provide best nursing services to transfusion patients in OPD, demands of transfusion patients in OPD and cognition of nurses to these demands were investigated. Methods By us-ing self- designed questionnaires which were modified and evaluated by specialists. Its coefficients of relia-bility and validity were above 0.91. Information about demands of transfusion patients in OPD and cognition of nurses to these demands were gathered and statistically analyzed. Results The investigation results showed that demands of patients in OPD were much higher than nurses' perceptibility. And there were dif-ferences among all kinds of patients. Conclusions Transfusion patients in OPD need better services. There exists differences between demands of patients and cognition of nurses to these demands. In order to give better nursing services, nurses should give intensive care to patients on safe, love and home, respect and self- actualization.

Objective To evaluate the Chinese version of Benefit Finding Scale (BFS) for breast cancer patients.Methods After consent of the author,according to the flow path of scales,we established the psychometric properties of the Chinese version of BUS,a convenience sample of 293 patients were recruited for evaluation.Results The Chinese version of BFS was comprised of 19 items,Cronbach's α coefficient was 0.911,test-retest reliability was 0.812,I-CVI was 0.833～1.000,S-CVI was 0.955.Meanwhile,exploratory analysis showed that the most interpretable solution consisted of 3 factors,the accumulative variance contribution which explained 55.101％ of variance of the total scale.The related validity showed that the correlative coefficient of Chinese version of BUS and Posttraumatic Growth Inventory (PTGI) was 0.745.Conclusions It suggests that the 19-item Chinese version of the BFS has good reliability and validity,which could be used as a research tool for measuring breast cancer patients' benefit finding.

Objective To explore the influence of Azithromycin on helper T lymphocyte cell(Th)1/Th2 in peripheral blood of children with bronchitic asthma.Methods Twenty-four asthmatic children and 20 healthy children were selected.Peripheral blood mononuclear cells (PBMC) were isolated from venous blood and made into cells suspension in aseptic condition.0.2 mg/L,0.1 mg/L,0.05 mg/L and 0 mg/L Azithromycin were added into the cultures in asthmatic group.The control group was not interfered with Azithromycin.The supernatant was collected after 48 h.The levels of IFN-?,IL-4 and IL-10 in the supernatant were determined by enzyme-linked immunosobent assay(ELISA).SPSS 11.5 software was used to analyze data.Results 1.The level of IL-4 produced from PBMC of asthmatic group was significantly higher than that of control group(P0.05).2.Azithromycin 0.1 mg/L more promoted the secretion of IL-4 than the other 3 concentrations(Pa0.05).3.Azithromycin 0.2 mg/L and 0.1 mg/L more increased the level of IL-10 than the control group(P0.05).Conclusions The routine drug level of Azithromycin(0.1 mg/L) had no effects on the imbalance of Th1/Th2 of asthmatic children,but could modulate the immunological function by up-regulating the level of IL-10.

Objective To study the expression and pathologic significance of CD147,cyclophilin A (CyPA)and cyclophilin B(CyPB)in psoriatic lesions.Methods Immunohistochemical method was ap- plied to detect the expression of CD147,CyPA and CyPB in skin specimens of 15 patients with psoriasis pustulosa(PP),20 patients with progressive psoriasis vulgaris(PPV),and 20 patients with inactive psori- asis vulgaris(IPV).Immunoreactivity intensity distribution index(IRIDI)was calculated to assess the expres- sion intensity of CD147,CyPA and CyPB.Results CD147,CyPA and CyPB were detected in all speci- mens.The IRIDI scores of CD147 and CyPA were significantly higher in keratinocytes of psoriatic lesions than in those of the control specimens(all P0.05).The IRIDI score of CyPB in T lymphocytes of PP lesions was significantly elevated than that in PPV lesions,which was in turn higher than that in IPV lesions(all P0.05).Conclusion CD147,CyPA and CyPB may play a role in the occurrence and development of psoriasis.

Objective:To explore the validity of a function assessing tool based on the International Classification of Functioning, Disability and Health′s (ICF′s) rehabilitation set in assessing aging-related disability.Methods:A total of 1610 elderly people from 15 nursing homes across China were assessed using the tool based on the ICF′s rehabilitation set and with the 12-item short form health survey (SF-12). The structural validity of the responses was analyzed using factor analysis, and criterion-related validity was also evaluated.Results:The factor analysis yielded three factors with eigenvalues greater than 1. Their cumulative explanatory power was 74.4%. Item d550 eating had double loading in the factor analysis. The item scores and the total scores of the disability assessment tool were significantly negatively correlated with the physiological function domain scores and the psychological function domain scores.Conclusion:The function assessment tool based on the ICF′s rehabilitation set when combined with a numerical rating scale has good structural and criterion-related validity in the assessment of disability due to aging.

Objective To investigate the effects of PM2.5 on tear film function and corneal epithelial structure in mice.Methods Totally 24 male BALB/c mice (24 eyes) were divided into two groups:group A (with PBS eye drops,n =12),group B (5 mg · mL-1 PM2.5 eye drop group,n =12).PBS and PM2.5 eye drop were given with four times per day for 7 consecutive days in right eye.Tear secretion level was measured with phenol red thread.Break-up time (BUT) of tear film was tested,and corneal fluorescein staining (FL) was scored before therapy and 1 day,4 days and 7 days after droppings and HE staining was performed 7 days after droppings,respectively.Results There was no significant difference in the tear secretion levels,BUT,FL between the groups A and B before treatment (all P ＞ 0.05).At 4 days,7 days after treatment with PM2.5,the mean differences of the group B showed all items significantly changed compared with those before treatment (all P ＜ 0.05).For the group A,there was no statistical change in tear secretion levels,BUT,FL at 7 days after treatment (all P ＞ 0.05).There were statistical differences in all items between group A and B at each time point (all P ＜ 0.05).At 7 days after therapy,the mean layers of corneal epithelial cells in the group A (4 ± 1) was significantly lower than that in the group B (7 ±l) (P ＜0.05).The group B showed that the whole corneal fluorescein staining obviously increased,and corneal epithelial cell layer was thickened.Conclusion PM2.5 can influence tears film function and damage the corneal epithelial structure in mice.
