Background:Among the previous studies about the ADL recovery and its predictors, the researches and resources used to study and protect the baseline-independent older patients from being permanently ADL-dependent was few. We aimed to describe the level of activities of daily living (ADL) at discharge and ADL change within 6 months after discharge in older patients who were ADL-independent before admission but became dependent because of acute illness, and to identify the predictors of early rehabilitation,so as to provide the basis to early intervention. Methods: Stratified cluster sampling was used to recruit 520 hospitalised older patients who were ADLindependent from departments of internal medicine at two tertiary hospitals from August 2017 to May 2018. Demographics, clinical data, and ADL status at 1, 3, and 6 months after discharge were collected. Data were analysed using descriptive statistics, Student's t-test, Pearson's chi-square test,Spearman's correlation analysis, binary logistic regression analysis, and receiver operating characteristic (ROC) curve analysis. Results: There were 403 out of 520 patients completing the 6-month follow-up, and 229 (56.8%) regained independence at 6 months after discharge. There was an overall increasing trend in ADL with time. The recovery rate was the highest within the first month after discharge, gradually declined after 1 month, and changed less obviously from 3 to 6 months after discharge (p < 0.001). ADL score at discharge (OR = 1.034, p < 0.001), age (OR = 0.269, p = 0.001), post-discharge residence (OR = 0.390, p < 0.05), and cognition status at discharge (OR = 1.685, p < 0.05) were predictors of ADL recovery. The area under the curve of the four predictors combined was 0.763 (p < 0.001). Conclusion: Studying ADL recovery rate and its predicting indicators of the baseline independent inpatients at different time points provide a theoretical reference for the formulation of nursing plans and allocation of care resources.

Objective. To investigate the role and mechanism of aspirin in myocardial injury induced by myocardial ischemia-reperfusion in rats through STAT3 signaling pathway. Methods. Sixty rats were randomly divided into three groups: the sham operation group, MI/R group, and MI/R+aspirin group (aspirin group). The rats in the sham operation group did not ligate the LAD coronary artery, while the aspirin group ligated the LAD coronary artery, which caused the suture to be loosened after 30 minutes ischemia, and 60 mg/kg aspirin was injected into the tail vein 10 minutes before reperfusion. After three hours of reperfusion, the ultrasound system was used to collect hemodynamic parameters, including ejection fraction (EF%), shortening fraction (FS%), and left ventricular end-systolic pressure (LVESP%) and left ventricular end-diastolic pressure (LVEDP%). Finally, the rats were euthanized; then, blood samples were taken for biochemical examination, myocardial tissue was collected, and the left ventricle was used for subsequent experiments. The gene expression levels of Bax and Bcl-2 were detected by PCR. The protein expression levels of Bcl-2, Bax, p-JAK2, total JAK2, p-STAT3, and total STAT3 were detected by Western blot. Results. Compared with the sham operation group and the aspirin group, the area of myocardial infarction in the MI/R was significantly increased ( p < 0.05 ). In terms of hemodynamic parameters, LVEDP was significantly elevated in the MI/R group. The results of PCR showed that compared with the MI/R group, the mRNA expression of Bax in the aspirin group was significantly decreased, while that of Bcl-2 was significantly increased ( p < 0.05 ). Western blot analysis showed that compared with the MI/R group, aspirin pretreatment significantly increased the expression levels of p-STAT3 and p-JAK2 ( p < 0.05 ). Conclusion. The mechanism of aspirin preconditioning to protect the heart from MI/R injury appears to be related to JAK2/STAT3 and related to the activation of the signaling pathway.

Tetrastigma hemsleyanum Diels et Gilg. (T. hemsleyanum) is an economically and medicinally valuable species within the genus Tetrastigma. However, the material basis of its pharmacological action and the biomarkers associated with its anti-cancer and anti-inflammatory effects are still unclear. Additionally, the T. hemsleyanum industry cannot grow because there is a lack of a scientific, universal, and measurable quality control system. This study aimed to explore the chemical basis quality markers related to the anti-cancer and anti-inflammatory effects of T. hemsleyanum to establish an effective quality evaluation method. UPLC-Q-TOF-MSE fingerprint profiles of T. hemsleyanum from different origins were established. Pharmacodynamic studies used HepG2 and HuH-7 cells and LPS-induced RAW264.7 to evaluate the anti-tumor and anti-inflammatory effects of the active ingredients. The spectrum-effect relationships between UPLC fingerprints and anti-cancer and anti-inflammatory activities were evaluated using PCA and PLSR statistical methods. Moreover, docking analysis was performed to identify specific active biomarkers with molecular targets associated with cancer and inflammation. Chlorogenic acid, quinic acid, catechin, kaempferol 3-rutinoside, apigenin-8-C-glucoside, and linolenic acid were associated with anticancer activity, while chlorogenic acid, quercetin, quinic acid, kaempferol 3-rutinoside, rutinum, apigenin-8-C-glucoside, and linolenic acid were associated with anti-inflammatory activity. The spectrum-effect relationship of T. hemsleyanum was successfully established, and the biomarkers for anti-cancer and anti-inflammatory effects were preliminary confirmed. These findings provide a theoretical basis for the elucidation of the substance basis of T. hemsleyanum and lay the foundation for its rapid identification, quality control, industrial research, and utilization.

Aims: To investigate the change and associated factors of care needs within 6 months post-discharge in older people with hospital-associated disability, and the relationship between time-varying care needs and physical function.Background: Older people with hospital-associated disability will have various care needs post-discharge. Understanding their care needs will help to improve their health. However, studies on this population are still limited.Design: A longitudinal study. Methods:The older people who met the inclusion and exclusion criteria were selected in 2 tertiary hospitals in Zhejiang Province, China. The questionnaire survey method was used to collect data about socio-demographic characteristics, physical function and care needs. The data of 375 older people who completed follow-up were analysed using logistic regression analysis, generalised estimating equations and generalised additive mixed model. We followed STROBE checklist for reporting the study. Results:The care needs of the older people with hospital-associated disability declined unevenly, it decreased rapidly in the first three months, and then flattening out. The percentage of people with care needs in each dimension decreased over time, but daily care and rehabilitation needs were consistently more important. Sociodemographic factors and physical function had different effects on need at different time points, the physical function was the main factor among them. There were non-linear relationships between the physical function and different care needs with different inflection points. Conclusion:This research revealed change patterns of the care needs of older people with hospital-associated disability post-discharge and the non-linear relationship between physical function and care needs. These findings may help healthcare professionals and caregivers to provide accurate care.
