Objective To understand the influence of nursing home service experience on humanistic caring ability of nurses.Methods Using the phenomenological method,15 clinical nurses after participation of nursing home service were interviewed,and the data were analyzed using 7 step Colaizzi method.Results 3 themes were extracted:service experience,the understanding of humanistic nursing care,influence of service experience on humanistic caring ability of nursing.Conclusions The participation of nurses in the nursing home services can promote the humanistic caring ability of nursing,which is a positive way of cultivating the ability of humanistic care ability.

Objective To investigate the serum levels of biochemical indexes such as calcium,phosphorus,iron,zinc,and alkaline phosphatase of children in Kaschin-Beck disease areas and control areas in Qinghai Province.Methods According to the results of Kaschin-Beck disease monitoring in Qinghai Province,Tangnaihai Township of Xinghai County and Gandu Town of Hualong County were chosen as Kaschin-Beck disease areas and Qushian Township of Xinghai Country was chosen as a control.Children aged 7 to 15 in boarding schools in these areas were chosen as the study subjects in June 2014.Serum alkaline phosphatase level was determined by enzyme colorimetry and the serum iron,zinc,calcium and phosphorus levels were determined by colorimetry.Calcium to phosphate ratio was calculated at the same time.Results Fifty-nine qualified serum samples of children were sampled in Kaschin-Beck disease areas and 45 in control area.Serum alkaline phosphatase levels in Kaschin-Beck disease areas and control area were (311.34 ± 85.31) and (264.09 ± 73.44)U/L,respectively,and the difference was statistically significant (t =-2.97,P ＜ 0.05).Children's serum phosphorus levels in Kaschin-Beck disease areas and control area were (1.62 ± 0.17) and (1.43 ± 0.13)mmol/L,respectively,and the difference was statistically significant (t =-6.29,P ＜ 0.05).Calcium to phosphorus ratio were 1.62 ± 0.17 and 1.82 ± 0.21,respectively,and the difference was statistically significant (t =5.53,P ＜ 0.05).Compared with the control area,the level of children's serum zinc was (19.96 ± 1.70) and (20.59 ± 2.45)μmol/L;the level of serum calcium was (2.59 ± 0.11) and (2.57 ± 0.11)mmol/L;and the level of serum iron was (15.06 ± 7.02) and (17.01 ± 6.70)μmol/L.The differences between these three biochemical indicators were not statistically significant between Kaschin-Beck disease areas and control area (t =1.39,-0.64,1.44,all P ＞ 0.05).Conclusion In Kaschin-Beck disease areas in Qinghai Province,the level of children's serum alkaline phosphatase and phosphorus have increased markedly and the calcium to phosphate ratio has decreased obviously.

Objective Inflammatory bowel disease(IBD)is an unexplained chronic and recurrent inflammatory disease of the intestine,including ulcerative colitis(UC)and Crohn′s disease(CD).At present, the etiology and pathogenesis of IBD are still not clear,and it is believed to be related to the environment, inheritance,infection,immunity and other factors.With the increase of people′s living standard and the economic and social development,the incidence of IBD in China is a rising trend year by year,the impact of diet on the incidence of IBD and the influence of nutritional support on the prognosis of IBD have attracted more and more attention.Vitamin is one of the seven nutrients and is an indispensable part of the health of the body.In recent years,some vitamins have been proved to be related with the occurrence and development of IBD.
