Objective To observe the cell apoptosis, oxidative stress reaction and expressions of Bcl-2 and Bax in kid?ney of dietary zinc deficiency mice during growth period, and discuss the mechanism of renal cell apoptosis induced by zinc deficiency. Methods Thirty weaning male mice were randomly divided into zinc-deficient group and zinc-adequate group, and 15 mice for each group. Zinc-deficient group was fed with zinc deficiency diet (0.85 mg/kg), while zinc-adequate group was fed with enough zinc diet (30 mg/kg). The TUNEL method was applied to observe the cell apoptosis, and the apoptotic in?dex was measured. The content of SOD and MDA were detected to observe the oxidative stress reaction in kidney. The ex?pression levels of Bcl-2 and Bax protein were detected by Western blot assay. Results Compared with zinc-adequate group, the cell apoptosis and oxidative stress reaction were increased in zinc-deficient group. The expression of Bcl-2 de?creased, and the expression of Bax increased. The ratio of Bcl-2 and Bax declined in kidney of zinc deficiency mice. Conclu?sion Diet zinc deficiency in growth period may result in the decreased antioxidase, the increased oxidative stress reaction, and the changed Bcl-2 and Bax expression, which promote the occurrence of cell apoptosis in kidney.

Objective:To explore the diagnostic value of the serial position effect combined with delayed recall of auditory verbal learning test in diagnosing the elderly patients with different levels of cognitive impairment.Methods:A total of 310 subjects were enrolled and divided into three groups: the normal control group(NC group, n=128), the mild cognitive impairment group(MCI group, n=133)and the mild Alzheimer's disease group(mild AD group, n=149)matched for gender, age and education level.Comprehensive neuro-psychological tests were performed on all subjects, and the Auditory Verbal Learning Test-Huashan version(AVLT-H)was used to analyze the serial position effect.Results:There were significant differences in the primacy effect of the second and third time of immediate recall, short-term and long-term delayed recall among the three groups( P<0.05), but no difference was found in the recency effect between the MCI and mild AD groups( P>0.05). The long-term delayed primacy effect combined with the short-term delayed recall showed a better validity to distinguish those elderly subjects with different levels of cognitive impairment than other memorial indexes, and the correlative sensitivity and specificity were 83.21% and 71.43%(NC group vs.MCI group), 85.71% and 92.86%(NC group vs.mild AD group), 66.67% and 75.57%(MCI group vs.mild AD group), respectively. Conclusions:The long-term delayed primacy effect combined with the short-term delayed recall can assist in distinguishing elderly patients with different levels of cognitive impairment.
