The influence of help-seeking behavior in people with subjective memory complaints / 中华护理杂志

Objective To explore the influence factors of help-seeking behavior in people with subjective memory complaints (SMCs).Methods A total of 305 eligible SMCs people were recruited and investigated with illness perception questionnaire-memory (IPQ-M),GDS-15,Mini-mental State Examination (MMSE),auditory verbal learning test(AVLT).Subjects were comprised of two groups:help-seeking group(n=44) and non-help-seeking group(n=261).Results The ratio of SMCs people for help-seeking was very low,only accounted for 14.4％.The ratio for going to hospital to see a specialist memory clinic accounted for only 2.0％.Logistic regression analysis showed 6 related factors were prime motivators for help-seeking behavior,which were symptom (OR=1.455),treatment control (OR=2.456),emotional representation (OR=2.268),accepting dementia education (OR=1.576),lacking of blood supply to the brain(OR=1.115),not using brain(OR=2.079).Three causal attributions were obstructive factors for help-seeking behavior,which were loneliness (OR=0.253),aging (OR=0.450),and chance or bad luck (OR=0.374).Conclusion Illness perception-memory in subjects with SMCs had some prediction for help-seeking behavior.Community nurses should attach importance to illness perception-memory of SMCs people and help them promote help-seeking,so as to facilitate earlv screening,identification and prevention of dementia.

Primary active components in sepia: A qualitative and quantitative analysis / 第二军医大学学报

Objectives: To establish a method for qualitative and quantitative analysis of the major active components in sepia. Methods: Melanin was identified by dissoving it in a basic solution to see whether there was segregation of a black substance. Glycine, asparagines, glutamic acid and alanine in sepia were determined by HPLC-AccQ-Tag method and iron was determined by atomic absorption spectrophotometer. Results: Melanin in sepia was dissolved in 2 mol/L NaOH solution and black substance was obtained in 2 mol/L HCl solution. The recoveries of the above 4 amino acids and iron were within the range of 95%-105% with RSD<5% (n=6). The mean contents of glycine, asparagines, glutamic acid, alanine and iron in 3 batches of sepia samples were 7.37, 11.23, 12.05, 7.32 and 0.206 mg · g-1, respectively. Conclusion: The method in this article is feasible for quantitative and qualitative analysis of bioactive contents in sepia; it has good repeatibility and may be used for the quality control of sepia.
