Objective To explore the effect of rehabilitation training on self-care ability of patients with senile dementia. Methods One hundred and one senile dementia patients were divided into two groups with 53 cases in experimental group receiving targeted rehabilitation training besides routine nursing and 48 in control group only receiving routine nursing.Self-care ability of patients in the two groups was comparatively evaluated according to the activity of daily living scale (ADL).Result The ADL score and the total score of the experimental group were both higher than those of the control group (P<0.05).Conclusion Rehabilitation training according to the specific conditions of patients with senile dementia can improve their self-care ability in adapting to the society, delaying the progress of the disease and improving the quality of life.

Objective To identify primary gout biomarkers. Methods Isobaric tags for relative and absolute quantitation (iTRAQ) technique combined with liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used to screen differentially expressed proteins, and to identify potential biomarkers by analysis of the biological process, cellular components, molecular functions, KEGG pathways and protein-protein interactions. Difference between two groups were measured byt test. Results We identified 95 differentially expressed proteins (50 up-regulated proteins and 45 down-regulated proteins, respectively), and 20 significant KEGG pathways. Among them, glyceraldehyde-3-phosphate dehydrogenase (GAPDH), α-enolase (ENOA), phosphoglycerate kinase (PGK1), glucose-6-phosphate isomerase (G6PI) and moesin might play a role in the pathogenesis of primary gout. Conclusion iTRAQ technology can detect differentially expressed proteins from proteome, provides a strong theoretical basis for the study of biomarkers and evidence for the mechanisms in primary gout. However, further studies are needed.

OBJECTIVE:
To explore the regulatory mechanism of human hepatocyte apoptosis induced by lysosomal membrane protein Sidt2 knockout.
METHODS:
The Sidt2 knockout (Sidt2-/-) cell model was constructed in human hepatocyte HL7702 cells using Crispr-Cas9 technology.The protein levels of Sidt2 and key autophagy proteins LC3-II/I and P62 in the cell model were detected using Western blotting, and the formation of autophagosomes was observed with MDC staining.EdU incorporation assay and flow cytometry were performed to observe the effect of Sidt2 knockout on cell proliferation and apoptosis.The effect of chloroquine at the saturating concentration on autophagic flux, proliferation and apoptosis of Sidt2 knockout cells were observed.
RESULTS:
Sidt2-/- HL7702 cells were successfully constructed.Sidt2 knockout significantly inhibited the proliferation and increased apoptosis of the cells, causing also increased protein expressions of LC3-II/I and P62(P < 0.05) and increased number of autophagosomes.Autophagy of the cells reached a saturated state following treatment with 50 μmol/L chloroquine, and at this concentration, chloroquine significantly increased the expressions of LC3B and P62 in Sidt2-/- HL7702 cells.
CONCLUSION
Sidt2 gene knockout causes dysregulation of the autophagy pathway and induces apoptosis of HL7702 cells, and the latter effect is not mediated by inhibiting the autophagy-lysosomal pathway.
