Objective To explore the effect of nursing of Traditional Chinese Medicine on cognitive function among aged people with mild cognitive impairment in elderly care institution. Methods A total of 66 cases with mild cognitive impairment elderly that previously were screened out from two pension institutions in Taiyuan city as the research objects. According to the endowment institutions where the objects of study dwelled was divided into control group (34 cases) and intervention group (32 cases). The intervention group accepted nursing of Traditional Chinese Medicine plan for four months. The control group received the disease related knowledge health education. The cognitive function of the two groups were assessed using the Montreal Cognitive Scale (MoCA) before and after the intervention. Results Before the intervention, two groups had no statistical significance in each dimension score and total score of MoCA. After the intervention, four dimensions scores including ability of visual spatial and execute , attention , delayed recall , directional force and the total score of the intervention group respectively were (2.67±1.09) points, (4.07±1.08) points, (1.97±0.81) points, (4.83±0.99) points, (18.80±1.74) points while the control group were (2.15 ± 0.71) points, (3.30 ± 0.63) points, (1.39 ± 0.97) points, (4.24 ± 1.41) points, (15.06 ± 2.98) points, and the difference was statistically significant (t=1.91-6.06, P < 0.05 or 0.01) ;Before intervention the language score, delayed recall score and the total score of the intervention group were (1.43±0.77) points, (1.57±1.10) points, (17.27±1.99) points, respectively while after the intervention were (1.80 ± 0.66) points, (1.97 ± 0.81) points, (18.80 ± 1.74) points, there was statistically significant difference (t =-2.16,-2.11,- 4.34, P < 0.05 or 0.01). Conclusions Nursing of Traditional Chinese Medicine can delay the process of cognitive decline of mild cognitive impairment in the elderly, and have a certain effect on prevention and treatment of patients with mild cognitive impairment.

[Abstract] Objective: To investigate the effect of lncRNA SNHG15 targeting miR-153 on cell viability and apoptosis of breast cancer cells and its apoptotic mechanism. Methods:The expression of SNHG15 in breast cancer cell lines(MDA-MB-231, BT-549 and MCF-7)
were detected by Real-time fluorescent quantitative PCR (qPCR). MDA-MB-231 cells were divided into control (Ctrl) group, si-NC group, si-SNHG15 group, si-SNHG15+anti-NC group and si-SNHG15+anti-miR-153 group. Cell viability and apoptosis rate were detected by MTT and Flow cytometry, respectively. The targeting relationship between SNHG15 and miR-153 was verified by Dual luciferase report gene system. Mitochondrial membrane potential fluorescent probe (JC-1) staining method was used to detect cell mitochondrial membrane potential. The expressions of mitochondrial apoptosis-related proteins (Bcl-2, Bax, caspase3, cleaved caspase3
[c-caspase3] and Cyt-C)were detected by Western blotting. Results: The expression of SNHG15 in breast cancer cells was significantly
higher than that in human normal mammary epithelial MCF10A cells (P<0.01). There was a targeting relationship between SNHG15
and miR-153. Compared with the control group, the cell viability and mitochondrial membrane potential of MDA-MB-231 cells in si-SNHG15 group were decreased, while apoptosis rate was increased (all P<0.01); the expressions of Bcl-2 and caspase3 were
decreased while expressions of Bax, c-caspase3 and Cyt-C were increased (all P<0.01). However, co-transfection of si-SNHG15 and
anti-miR-153 significantly attenuated the effects of si-SNHG15 on cell viability, apoptosis, mitochondrial membrane potential and
expressions of Bcl-2, Bax, caspase3, c-caspase3 and Cyt-C (all P<0.01). Conclusion: lncRNA SNHG15 can target miR-153 to induce
apoptosis of MDA-MB-231 cells, and the mechanism may be related to the regulation of apoptosis of mitochondrial pathway.

Objective:To retrieve, evaluate and summarize the best evidence of exercise reversal intervention in the elderly with cognitive frailty, and to provide evidence for guiding exercise in elderly patients.Methods:This study was a summary of evidence-based nursing evidence. Based on the PIPOST (P: Population; I: Intervention; P: Professional; O: Outcome; S: Setting; T: Type of evidence) mode, the evidence of exercise reversal intervention in the elderly with cognitive frailty in 25 relevant guideline network and association websites, Chinese and foreign language comprehensive databases such as PubMed, CINAHL, Web of Science, Embase, Chinese Biomedical Database, China National Knowledge Internet and others were searched, extracted and integrated. The retrieval time was from January 1, 2013 to February 14, 2022.Results:A total of 22 articles were included, including 3 guidelines, 2 expert consensuses, 1 clinical decision-making, 1 evidence summary, 9 Meta analysis, and 6 randomized controlled trials. Finally, 28 pieces of the best evidence including 7 dimensions were namely formulate principles,overall assessment, exercise mode, exercise intensity, exercise time and frequency, exercise management, health guidance.Conclusions:This study summarized the best evidence of exercise intervention in the elderly with cognitive frailty, which are systematic, comprehensive, rigorous, and reliable. It can provide references for healthcare administrators to dynamically evaluate patients′cognitive frailty status, formulate personalized exercise programs, and standardize exercise guidance for patients, so as to delay or even reverse cognitive frailty.

PEP06 is a novel endostatin-Arg-Gly-Asp-Arg-Gly-Asp(RGDRGD)30-amino-acid polypeptide featuring a terminally fused RGDRGD hexapeptide at the N terminus.The active endostatin fragment of PEPO6 directly targets tumor cells and exerts an antitumoral effect.However,little is known about the kinetics and degradation products of PEP06 in vitro or in vivo.In this study,we investigated the in vitro metabolic stability of PEP06 after it was incubated with living cells obtained from animals of different species;we further identified the degradation characteristics of its cleavage products.PEP06 underwent rapid enzymatic degradation in multiple types of living cells,and the liver,kidney,and blood play important roles in the metabolism and clearance of the peptides resulting from the molecular degradation of PEP06.We identified metabolites of PEP06 using full-scan mass spectrometry(MS)and tandem MS(MS2),wherein 43 metabolites were characterized and identified as the degradation metabolites from the parent peptide,formed by successive losses of amino acids.The metabolites were C and N terminal truncated products of PEP06.The structures of 11 metabolites(M6,M7,M16,M17,M21,M25,M33,M34,M39,M40,and M42)were further confirmed by comparing the retention times of similar full MS spectrum and MS2 spectrum information with reference standards for the synthesized metabolites.We have demonstrated the metabolic stability of PEP06 in vitro and identified a series of potentially bioactive downstream metabolites of PEP06,which can support further drug research.
