Objective To assess the quality of randomized controlled trials (RCTs) of delirium prevention of elderly published in China.Methods The literatures from China National Knowledge Infrastructure(CNKI),WANFANG Data and VIP Database for Chinese Technical Periodicals were evaluated according to Cochrane collaboration's tool for assessing risk of bias and Jadad scale.Results A total of 53 RCTs were included,14 (26.4％,14/53) described radom number table used to generate the random allocation sequence,4 (7.5％,4/53) conducted experiments in a blinded manner,7 (13.2％,7/53) did not use intentionto-treat to analyse those who did not complete the study,9 (17.0％,9/53) had high risk of other bias,none described allocation concealment mechanism and blinding to participants and intercention implementers.Based on Jadad scales,the score was 1-4,average score was (2.3±0.8),19 (35.8％,19/53) were high-quality literatures.Conclusions The quality of present published literatures is not high,the further domestic studies should be designed high-quality to better improve clinical practice.

Objective To explore the action mechanism of basic fibroblast growth factor (bFGF) on vascular smooth muscle cells (VSMCs) in spontaneously hypertensive rats (SHR).Methods Ts were obtained from SHR and SD rats.The aortic VSMCs were cultured in vitro by tissue explant method.VSMCs were treated with different concentration of exogenous bFGF (0 ng/ml,20 ng/ml,40 ng/ml,60 ng/ml,80 ng/ml,100 ng/ml) for 48 h,then cell proliferation was detected by 3 (4,5 dimethylthiazol)2,5 diphenyltetrazolium bromide (MTT) colorimetric assay.VSMCs from SHR in control group were treated with bFGF (100 ng/ml) for 48h.VSMCs from SHR in treatment group were treated with bFGF (100 ng/ml) plus Proteinkinase C(PKC) inhibitor (staurosporine) for 48 h.Results After treatment with different concentration (0 ng/ml,20 ng/ml,40 ng/ml,60 ng/ml,80 ng/ml,100 ng/ml) of bFGF for 48 h,the values measured by MTT colorimetric method were 0.402 ± 0.103,0.605 ±0.090,0.696 ± 0.131,0.812 ± 0.080,0.901 ± 0.065,1.056±0.078 respectively in aortic VSMCs from SD rats,and 0.404±0.065,0.507±0.078,0.608±0.057,0.704 ± 0.107,0.812 ± 0.097,0.908 ± 0.032 respectively in aortic VSMCs from SHR.Compared with control group,the values measured by MTT colorimetric method were decreased in treatment group (P＜0.05).The proliferative effect of bFGF in aortic VSMCs from SHR was attenuated after administration of PKC inhibitor staurosporine.Conclusions Exogenous bFGF administration promotes VSMCs proliferation in SHR and SD rats in a concentration-dependent manner.PKC plays an important role in the signal transduction mechanism in VSMCs proliferation by exogenous bFGF.

This paper introduced the basic concept, development background, development situation and pattern of acute care of the elderly unit, so as to improve the public cognition and development of acute care of the elderly unit.The practices of acute care of the elderly unit could improve the hospital outcome of elderly patients and enhance the quality of life.

Objective:To summarize the nursing experience of an elderly patient with anorexia and weight loss.Methods:The patient was admitted to the acute care for the elderly unit(ACE) after the acute assessment, and multidisciplinary team care was performed on the patient. To recovery patient to a healthy level and to return quickly the family and society, the team applied the comprehensive assessment technology for the elderly to comprehensively assess the patient′s situation, including multidisciplinary team rounds, routine ACE meetings, implementation of patient-centered care.Results:The anorexia and nutritional status were improved, to be discharged after 8 days. There were no functional declines and hospital-related complications during hospitalization.Conclusion:ACE improves the quality of care and patient outcomes in elderly patients.

Objective To translate the 3-minute diagnostic confusion assessment method(3D-CAM)into Chinese,to revise it,and to test its reliability and validity in elderly patients.Methods We translated and culturally adapted 3D-CAM into Chinese.The sample was formed by 230 elderly patients over 65 years of age.We tested inter-assessors reliability and criterion validity (diagnostic validity)and then computed the sensitivity,specificity,positive predictive value,and negative predictive value of the Chinese version of 3D-CAM.Results Correlation analyses between each item and its total score showed that the correlation coefficients ranged between 0.290 and 0.724,all reaching statistical significance(P＜0.01).Inter-assessor reliability in a sample size of 30 patients resulted in a kappa value of 0.78 (P ＜ 0.001).Compared with the gold standard,the diagnostic and statistical manual of mental disorders(DSM-5)by American Psychiatric Association(APA),the sensitivity of the Chinese version of 3D-CAM was 94.73％,the specificity was 97.92％,the positive predictive value was 90.00％,and the negative predictive value was 98.95％.Conclusions The Chinese version of 3D-CAM has achieved satisfactory reliability and validity through pilot runs in surgery and internal medicine inpatients,proved to be easy and convenient to administer,and can be used as an assessment tool for delirium in elderly surgery and internal medicine patients.

Objective Summing up the care experience about a patients with acute illness and frailty. Methods Taking care of the patients based on the acute care for the elderly unit model (ACE), using the methods of admission assessment, interdisciplinary team, function-centered care model, ward environment design, early care transition planning and meeting with family members. Results The patient was discharged 10 days later, without function decline or complication related to admission. Conclusions ACE unit model is a successful care model which take a holistic care for old patients in order to maintain the function during hospitalization.

Gut microbiota plays an important role in development of diabetes with frailty. Therefore, it is of great significance to study the structural and functional characteristics of gut microbiota in Chinese with frailty. Totally 30 middle-aged and the aged participants in communities with diabetes were enrolled in this study, and their feces were collected. At the same time, we developed a metagenome analysis to explore the different of the structural and functional characteristics between diabetes with frailty and diabetes without frailty. The results showed the alpha diversity of intestinal microbiota in diabetes with frailty was lower.
