Objective To investigate the distribution of water fluoride and the present status of water-improving defuoridation projects in the endmie fluorosis areas in Gansu Province in 2006. Methods The content of fluoride in drinking water in 18 endemic disease counties was screened, and the defluoridation projects built after the 1980s were supervised and inspected. The content of fluoride in drinking water was assessed by F-ion selective electrode. Results Fluoride content was determined in water of 6260 sources in 1252 fluorosis villages in 18 counties, with 63.50% (3975/6260)≤1.0 mg/L and 36.50%(2285/6260)>1.0 mg/L. Nine hundred and ninty-seven water-improving and clefluoridation projects had been investigated in 16 counties, among which 95.49% (952/997) were function well, and projects intermittently running or abandoned respectively accounted for 3.11% (31/997) and 1.40%(14/997). Nine hundred and eighty-three sources of water treated by the water-improving and defluoridation projects had been determined for fluoride content, it turned out that 91.76% (902/983) were within the standard, only 8.24% (81/983) were not; as for outlet and leftover water of 934 water-improving and defluoridatian projects determined for water fluoride content, qualified projects accounted for 92.08% (860/934) and 91.97%(859/934), leaving 7.92%(74/934) and 8.03%(75/934) disqualified, respectively. Water-improving and defluoridation projects mostly relied on drilling a well in gaining under-ground water or collecting surface-ground water, so under-ground water and surface-ground water are the majority. Conclusions Water fluoride content exceeds the standard in some of the villages. A few projects do not function well. Fluorosis damage still exists in Gansu Province, therefore countermeasures for endemic fluorosis must be carried out as promptly as possible and surveillance on water-improving and defluoridation projects must be strengthened and managed.

Objective: To set up a new method - quantitative analysis of multi-components by single-marker(QAMS) to determine eight components - notoginsenoside R1, ginsenoside Rg1, Re, Rb1 and Rd, harpagoside, cryptotanshinone and tanshinone I in Fufang Xueshuantong(FX) capsule simultaneously, and validate its accuracy and feasibility for application in preparation. Methods: FX capsule was used as the research object, notoginsenoside R1 was selected as marker under 203 nm to evaluate the quality of ginsenoside Rg1, Re and Rb1, Rd, and cryptotanshinone as marker under 270 nm to evaluate the quality of harpagoside and tanshinone I. The relative correction factors (RCF) of components were calculated. The method was validated by comparison of the quantitative results between external standard method and QAMS method. Results: No significant differences were found in the quantitative analysis of components by external standard method and QAMS method. Conclusion: It is a convenient and accurate method to determine multi-components when authentic standard substances are not available. It can be used to control the quality of FX capsule.

PURPOSE: The purpose of this study was to identify a causal relationship among major satisfaction, career decision autonomy, and career search behavior of nursing college students in clinical practice experience. METHODS: Data were collected using a self-reported questionnaires from 197 nursing students in S city from December 1 to 23, 2016. These were then analyzed by descriptive statistics, ANOVA, t-test, Pearson correlation coefficient, and multiple regression using SPSS/PC+ program. RESULTS: The results suggest that major satisfaction was correlated with career decision autonomy; likewise, major satisfaction was correlated with career search behavior. The factors influencing career search behavior were grades and major satisfaction. CONCLUSION: It is necessary to develop a learning method considering interest and aptitude to increase the satisfaction of the major and to apply the various programs to understand the self and the work environment so as to determine how desirable the course will be.

The cause of essential hypertension is yet unknown, but in general is caused by interaction of hereditary factors, diet, obesity, lack of exercise and stress. The aging process influences various physiological mechanism related to regulation of blood pressure. So elderly hypertensives have a tendancy to consider the disease as a result of the physiological aging process. This attitude causes many complications, worsening of the disease and even early death because of inappropriate care. In order to improve self-management of elderly hypertensives in this study the researcher examined the effect of blood pressure regulation by an education program that improves self-care behavior, through increasing self-efficacy. The education program consisted of group education on hypertension and self-care strategies, and encouraging and reinforcing self-efficacy resources such as verbal persuation, performance accomplishment and vicarious experiences. A quasi-experimental pre-and post-test design was used. Thirty-two elderly hypertensives participated in the study. Eighteen in the education group and fourteen in the control group. The education program consisted of eight sessions twice a week for four weeks. There was no intervention for the control group. Data were analysed using SPSS for Windows(Version 8.0). The results were as follows. 1. There was a significant decrease in systolic and diastolic blood pressure between the experimental group and control group over three different times, and interaction by groups and over time. 2. There was no significant difference in the level of self-care behavior between the experimental group and control group over three different times, and interaction by groups and over time. 3. There was significant difference in self-efficacy of experimental and control group, depending on the measuring period, but there was no difference between these groups on interaction by groups and over time. 4. There was positive correlation between self efficacy and self care behavior depending on the measuring period. There was negative correlation between diastolic blood pressure and self-care behavior on the posttest of the program, and between systolic blood pressure and self-care behavior on the follow-up test of the program. Findings indicate that this study will contribute to develop nursing strategies for the regulation of blood pressure for the elderly, which is easy for the elderly to learn as a nonpharmacologic approach.

PURPOSE: This study was performed to explore the effect of senior simulation on nurses' attitudes toward the elderly. METHOD: Twenty-seven nurses working in various settings such as acute hospitals, community health centers, geriatric hospitals, and clinics were recruited. Among them, 25 subjects completed the whole experimental protocol. Aging Semantic Differential Scaling was utilized to evaluate attitudes toward the elderly and 'Suit for Experiencing Being Aged' from the Sakamoto Model was provided for the experiment. Before and after the experiment subjects filled out questionnaires. RESULT: Attitude score before experiment was 4.36, which indicates neutral attitude. Objective attitude scores were not different significantly after experiment. However subjective statements indicated attitude changes in a positive way. CONCLUSION: Senior simulation can affect nurses' attitude toward elderly in subjective way. That is, nurses became more empathetic and understanding to elderly's physical limitations and felt more initiative nursing approach were needed in caring elderly.

PURPOSE: This study aims to examine the influence of vitamin D and calcium on depression and cognitive function of the elderly living alone in a city. METHODS: The participants were registered in eight senior centers in S city and they had lived alone. Data were collected between November 28, 2014 and March 7, 2015. A total of 155 people participated in data collection to measure the serum vitamin D, the serum calcium, depression, and cognitive function. The data were analyzed with t-test, ANOVA, Pearson's correlation and multiple regression analysis. RESULTS: There were significant differences in depression according to gender and perceptions of health status. Depression correlated significantly with the serum calcium and perceptions of health status, and a stepwise regression analysis showed that the perceptions of health status were significant. There were significant differences in cognitive function according to education level and age. Cognitive function correlated significantly with the serum vitamin D and a stepwise regression analysis showed that education level and age were significant. CONCLUSION: Consequently, elderly people with poor perceptions of their health status need a depressive intervention program and those with a higher age and lower level of education need a cognitive function intervention program.

The photolytic behavior of deoxyadenosylcobalamin and methylcobalamin in water solution was investigated with high performance liquid chromatography. The results indicated that the photolytic cleavage rate increased with the light intensity, according to which a new method was developed to determine the concentration of vitamin B12 in fermentation broth. The samples were completely photolyzed after cell disruption. The content of vitamin B12 was obtained by determining the content of the hydroxycobalamin. The method shows many advantages, such as rapidness, high accuracy and low sample quantity needed, over traditions methods. The developed method may be used in the field of vitamin B12 fermentation.
