Objective To explore the effects of movement on hippocampal β-amyloid protein ( Aβ ) and amyloid precursor protein (APP) in senescence-accelerated and senescence-prone (SAMP8) mice, and the mechanism by which movement improves learning and memory in mice with a model of Alzheimer's disease. Methods Forty 3-month-old SAMP8 mice were divided randomly into a movement group and a control group. The movement group was trained with a running wheel 10 min daily, 5 days a week in the first month, and 20 min daily in the second month. Morphological changes in the hippocampus were observed under the microscope after HE staining. The expression of Aβ in the hippocampus was detected by immumohistochemical methods and APP mRNA expression was detected by RT-PCR two months later. Results HE staining showed neuron degeneration and death, chromatin condensation and vacuolar degeneration in the hippocampus of the 5-mouth-old SAMP8 mice of the control group. The movement group showed less neuron degeneration and death, and the morphology of most cells was normal The expression of Aβ in the hippocampus of the 5-month-old SAMP8 mice in the movement group was significantly lower than that in the control group. APP mRNA expression levels in the movement group were also significantly lower.Conclusions Movement can delay neuron degeneration and down-regulate Aβ and APP mRNA expression levels in the hippocampus of SAMP8 mice. It may be an important mechanism by which movement improves learning and memory in mice with a model of Alzheimer's disease.

Objective To investigate the effects of an enriched environment (EE) on the psychological and behavioral symptoms of senescence and on the level of plasmic adrenocorticotropic hormone (ACTH) and serum corticosteroid (Cor). MethodsTwenty male senescence-prone SAMP8 mice of 3 months old were divided randomly into an enriched environment (EE) group and a standard environment (SE) group.Five male senescence-resistant SAMR1 mice of the same age served as the control group.Behavioral symptoms were assessed after 2 months using autonomic activity and elevated-plus maze (EPM) test performance.Plasma ACTH and serum Cor were detected using radio-immunologic methods. ResultsAverage autonomic activity frequency and EPM open-arm times were significantly lower with the SAMP8 mice than among the control group,and the autonomic activity frequency was significantly higher in the EE group than in the SE group of SAMP8 mice.The average EPM open-arm times of the EE group and the SE were not significantly different.Average ACTH and Cor levels were both significantly lower in the SAMP8 mice,and the level of ACTH was significantly higher in the EE group than in the SE group.There was no significant difference in these groups' average Cor levels. ConclusionsThe SAMP8 mice of 5 months demonstrated significant mental and behavioral abnormalities,as well as down-regulated plasma levels of ACTH and Cor.EE An enhanced environment can reduce behavioral disturbance through up-regulating ACTH.

A 26?year?old male patient presented with facial depigmented patches for 10 years, some of which turned to blue?grey 7 years prior to the presentation. Before the white patches turned blue?gray, the patient developed contact dermatitis due to topical application of self?made drugs. Skin examination showed blue?gray hyperpigmentation on the left upper lip and in the temporal region, with white hairs in the hyperpigmented lesions on the left upper lip. Dermoscopy revealed irregularly shaped, light to dark blue?gray patches on the left upper lip, which were intermingled with white patches in some regions, and white hair stubs were observed in the white patches. Histopathological examination of temporal lesions showed decreased melanocytes in some regions in the epidermis, pigmentation in both basal and suprabasal layers, perivascular infiltration of a small number of chronic inflammatory cells and melanophages in the superficial dermis, and melanophage infiltration around sweat ducts. Finally, the patient was diagnosed with blue vitiligo. He refused to receive any treatments, and follow?up was under way.

A sequential clean-up method was developed for the quantification of 10 plant growth regulators in bean sprout by the gas chromatography / mass spectrometry (GC / MS). The analytes were firstly extracted by the acided acetonitrile. Extraction was concentrated and re-dissovled by methanol. Then, it was divided to two aliquots. One of that was analyzed for 2,4-D-butyl ester and 2,4-D-ethyl ester after the purification by QuECHERS cartridge. Another one was treated by MCS solid phase extraction column including diverse eluting steps. After eluting by 5 mL methanol, composition 1 was obtain, concentrated, and methyl esterified by 10% boron trifluoride methanol solution. The treated extract was used for the determination of 4-chlorophenoxy acetic acid, β-naphthyl acetic acid, 2,4-dichlorophenoxy acetic acid, indole acetic acid and indole butyric acid. Composition 2 collected by eluting with 5 mL 5% amonium methanol was used for the determination of paclobutrazol, Kinetin, 6-Benzylaminopurine. The clean-up procedures are designed according to different chemistry properties of these plant growth regulators. The results showed that after spiking of 0. 01-0. 1 mg / kg selected plant growth regulators, average recovery ranged from 70. 0% to 93. 2%and relative standard deviation were 5. 2% -12. 3% . Limit of quantification (LOQ S / N≥10) and limit of detection (LOD S / N≥3) were 0. 01-0. 025 mg / kg and 0. 003-0. 008 mg / kg respectively. The developed purification method is easy, fast and accurate, and can be applied to routine test of plant growth regulators in bean sprout.
