Serum level of soluble transferrin receptor in children with hemoglobin H disease / 中国当代儿科杂志

OBJECTIVE@#To investigate the serum level of soluble transferrin receptor (sTfR) and its association with the degree of anemia in children with hemoglobin H (HbH) disease.@*METHODS@#A total of 55 children with HbH disease were enrolled as the HbH group, and 30 healthy children were enrolled as the control group. The HbH group was further divided into a deletional HbH disease group and a non-deletional HbH disease group. A retrospective analysis was performed for hematological parameters and serum sTfR level in all groups.@*RESULTS@#Of the 55 children with HbH disease, 39 had deletional HbH disease and 16 had non-deletional HbH disease. Compared with the control group, the deletional and non-deletional HbH disease groups had significantly lower hemoglobin (Hb), mean corpuscular volume (MCV), and mean corpuscular hemoglobin (MCH) and a significantly higher serum level of sTfR. Compared with the deletional HbH disease group, the non-deletional HbH disease group had significantly lower red blood cell count (RBC) and Hb level and significantly higher MCV, MCH, and serum sTfR level. In children with HbH disease, serum sTfR level was negatively correlated with RBC and Hb level (r=-0.739 and -0.667 respectively, P<0.05) and positively correlated with MCV and MCH (r=0.750 and 0.434 respectively, P<0.05).@*CONCLUSIONS@#Serum sTfR level is associated the degree of anemia in children with HbH disease, and sTfR may be a target for the treatment of HbH disease.

A study on the Life quality and its influencing factors among the elderly with cardiovascular diseases in rural areas / 预防医学

Objective To evaluate the life quality among the rural elderly residents with cardiovascular diseases and to explore the influencing factors in order to provide evidences for developing prevention measures.Methods A random sampling technique was employed,a total of 620 residents with hypertension and coronary heart disease (CHD)aged over 60 years in Jinhua City was selected.And an investigation including questionnaire and life quality SF -36 scale was conducted.The influencing factors were analyzed by multiple linear regression.Results The average score of life quality among the rural residents with cardiovascular diseases was 69.10 ±17.86.Scores of all dimensions were significantly lower in the elderly (>=70 years)than that among the <70 years (P <0.05).There was significant difference on the scores in seven dimensions (PF,RP,BP,GH,VT,SF,RE)(P <0.05).Scores of patients with annual income of 5 000 yuan were significantly lower than those with annual income of 5 000 -20 000 yuan,while scores decreased when above 20 000 yuan.Smoking,alcohol and tea were the influencing factors of scores in each dimension (P < 0.05 ).Multiple linear regression analysis showed that age,family income,smoking and drinking were the risk factors of life quality (P <0.01). Conclusion The life quality of the elderly with cardiovascular diseases in rural areas is almost on a normal level,but scores of general health and mental health is lower.It's urgent to strengthen the chronic disease management in order to improve the life quality of rural elderly residents with chronic diseases.
