ABSTRACT
Objective:To develop a questionnaire on perimenopausal cognition and behavior and verify its reliability and validity, in order to provide an effective tool for evaluating perimenopausal women's cognition, doctor-seeking and doctor-following behaviors.Methods:Baseline survey, literature analysis and brainstorming were formed in the initial items, and group discussion and expert interview were performed to identify items of the form. By convenience sampling method, A survey was conducted on perimenopausal women in the communities around Chongqing Health Center for Women and Children from July to August 2019. Project analysis, exploratory factor analysis, confirmatory factor analysis, Pearson correlation analysis and reliability test were used to evaluate the questionnaire.Results:Two rounds of questionnaires were distributed in this study. In the first round, 260 questionnaires were distributed, 249 valid questionnaires were recovered, and the effective recovery rate was 95.8% (249/260). In the second round, 249 questionnaires were distributed, and the effective recovery rate was 96.4% (240/249). The questionnaire on perimenopausal cognition and behavior included 4 dimensions and 24 items. The cumulative contribution of variance was 66.330%, the Cronbach α coefficient was 0.893 and the spearman-brown half-fold coefficient was 0.773. Regarding to the construct validity, the correlation coefficient between factors and total score of the questionnaire was 0.567-0.860 ( P < 0.01). Confirmatory factor analysis showed that the approximate error root mean square was 0.055, the normal fitting index was 0.801, and the goodness of fit index was 0.828. Conclusions:The questionnaire has been proved to be reliable and valid. It can be used to evaluate perimenopausal women′s cognition, doctor-seeking and doctor-following behaviors.
ABSTRACT
Objective To investigate the role of sFas and sFasL in the development and progression of uterine cervix cancer(UCC)and the clinical significance of detecting them.Method Serum sFas and sFasL levels of 30 UCC patients were detected by enzyme-linked immunosobent assay (ELISA) before and after treatment (operation or chemotherapy),at the same time serum sFas and sFasL levels of 20 healthy volunteers were also detected by ELISA.Results Serum sFas and sFasL levels of UCC patients[(8.60±0.27),(2.96±0.65)μg/L] were obviously higher than those of healthy volunteers[(6.27±0.25),(0.21±0.05)μg/L],there was statistical significance (P＜0.05).Serum sFas and sFasL levels of those who had operations decreased obviously 2 weeks after the operation,serum sFas and sFasL levels of those who had chemotherapy 3 weeks later increased,there was statistical significance when compared before and after treatment (P＜0.05).Conclusions sFas and sFasL may play important roles in the development and progression of UCC,detection of serum sFas and sFasL levels may conduce to observe the changes of pathogenetic condition.
ABSTRACT
Southern blotting with a labeled and linearized pUC 19 DNA containing a specific fragment of 0. 24 kb DNA of Plasmodium vivax asexual blood stages (kindly offered by Dr. C. Kidson )was used for further identification of blood samples showing positive reaction by dot-blot hybridization. The results showed that those with positive reaction from patients with P. vivax, with P. falciparum or with fever but with negative microscopic findings were also positive by Southern blotting. It was confirmed that some of those positive with P. falciparum were likely to infect P. vivax at the same time. So did a part of those with fever but negative in the blood films (Figs. 1,2).
