ABSTRACT
Objective:To investigate the prevalence of the decline of intrinsic capacity(IC)and to explore the effect of intrinsic capacity decline on falls and hospital readmission during 1 year follow-up.Methods:A total of 311 elderly patients treated in Geriatrics Department of Zhejiang Hospital were enrolled.General information and intrinsic ability data, including cognitive(simple mental state inventory), motor(Tinetti-Balance Scale and 4 m test), vitality(grip strength and mini-nutrition assessment table), perception(self-rated vision or hearing impairment), and psychosocial(Geriatric depression scale), were collected at admission.Falls and hospital readmission within 1 year after discharge were followed up.Multivariate Logistic regression analysis was used to investigate the relationship of baseline intrinsic ability at admission with falls and hospital readmission during 1-year follow-up.Results:Of 311 elderly hospitalized patients, 282(90.7%)had intrinsic capacity decline.During 1 year follow-up, 38 elderly patients(12.2%)had falls and 69 elderly patients(22.2%)were hospital readmitted.After adjusting for confounding factors such as age, gender, education level, comorbidities, multiple medications, fear of falling, and assistive tool use and so on, Logistic regression analysis showed that decreased balance ability was a risk factor for falls within 1 year in elderly patients( OR=3.515, 95% CI: 1.089-11.346, P=0.036), and slow walking speed was a risk factor for one-year hospital readmission( OR=2.426, 95% CI: 1.181-4.983, P=0.016). Conclusions:Decreased motor capacity is closely associated with falls and hospital readmission within 1 year in older patients.Great attention should be paid to the assessment and intervention of motor ability in elderly patients.
ABSTRACT
This study aims to explore the impact of Rehmannioside D (RD) on ovarian functions of rats with diminished ovarian reserve (DOR) and its underlying mechanisms of action. A single injection of cyclophosphamide was performed to establish a DOR rat model, and fourteen days after the injection, the rats were intragastrically administrated with RD for two weeks. Rat estrus cycles were tested using vaginal smears. Ovarian tissues were histologically evaluated, the number of primordial, mature, and atretic follicles was calculated, and the apoptotic rate of granulosa cells. Follicle-stimulating hormone (FSH), luteinizing hormone (LH), and estradiol (E2 ) levels were determined by ELISA assays. Protein levels of Forkhead Box O1 (FOXO1), KLOTHO, Bcl-2, and Bax were investigated in ovarian tissues of DOR rats. The binding between FOXO1 and KLOTHO was verified by ChIP assay. High-dose administration of RD into DOR rats improved their estrus cycles, increased ovarian index, enhanced the number of primordial and mature follicles, reduced the number of atretic follicle number, and ovarian granulosa cell apoptosis in addition to inhibiting FSH and LH levels and upregulating E2 expression. FOXO1 and KLOTHO were significantly suppressed in DOR rats. FOXO1 knockdown partially suppressed the protective effects of RD on DOR rats, and KLOTHO overexpression could restore RD-induced blockade of DOR development despite knocking down FOXO1. FOXO1 antibody enriched KLOTHO promoter, and the binding between them was reduced in DOR group compared to that in sham group. RD improved ovarian functions in DOR rats and diminished granulosa cell apoptosis via the FOXO1/KLOTHO axis.
ABSTRACT
Objective:To explore the effect of medical care, elderly care and nursing management mode on self-care ability and blood pressure management in elderly patients with hypertension.Methods:From July 2018 to June 2019, 164 elderly patients with hypertension admitted into the outpatient department of the ZhejiangHospital were selected as the study objects by convenience sampling method, and randomly divided into the control group and the experimental group, 82 cases in each group. Routine hypertension management mode was given in the control group and medical care, elderly care and nursing management mode was given in the experimental group for 6 months. The Exercise of Self-Care Agency Scale (ESCA) scores and blood pressure control of the two groups were compared before and after intervention.Results:The ESCA total score and self-concept, self-care responsibility, self-care skills, and health knowledge scores of the experimental group were higher than those before intervention [(123.3±17.2) vs. (88.3±10.4) points, (26.8±3.7) vs. (20.6±3.0) points, (22.3±4.2) vs. (16.6±2.1) points, (29.3±4.1) vs. (17.6±2.4) points, (44.9±5.4) vs. (33.5±4.5) points], and higher than those of the control group [(90.0±10.2) points, (21.2±3.2) points, (16.1±2.1) points, (18.2±2.5) points, (34.5±4.2) points] (all P<0.05). The systolic blood pressure and diastolic blood pressure of the two groups after the intervention were lower than those before the intervention [control group: (142.5±7.8) vs. (161.6±8.5) mmHg (1 mmHg=0.133 kPa), (91.3±6.2) vs. (98.6±10.2) mmHg, experimental group: (132.2±8.5) vs. (160.6±8.1) mmHg, (84.2±7.4) vs. (98.1±10.3) mmHg], and the experimental group was lower than the control group (all P<0.05). The blood pressure control rate of patients in the experimental group was 88.8%, which was higher than the control group of 48.6% ( P<0.05). The satisfaction rate of quality of life in the experimental group was higher than that in the control group (28.8% vs. 18.1%), and the dissatisfaction rate was lower than in the control group (18.8% vs. 34.7%) ( P<0.05). Conclusion:The medical care, elderly care and nursing management mode can effectively improve the self-care ability and blood pressure management ability of elderly patients with hypertension.
ABSTRACT
Objective To investigate the detection rate of motoric cognitive risk syndrome (MCR)and explore the possible risk factors.Methods A total of 429 elderly patients from geriatric department of Zhejiang Hospital from October 2014 to September 2018 were recruited in the crosssectional study.General information and functional assessment including fall history,self-reported visual impairment and hearing impairment,depressive symptom,cognitive function and gait speed were collected.Patients with MCR were screened out according to the MCR diagnostic criteria.Multiple logistic regression analysis was used to analyze the associated risk factors.Results Seventeen patients(4.0％)met the MCR diagnostic criteria.The proportions of obesity,polypharmacy,cerebral vascular diseases,self-reported hearing impairment,depressive symptoms and slow gait were higher in MCR patients than in non-MCR patients(P＜0.05).Compared with non-MCR patients,MCR patients had lower mini mental state examination (MMSE) scores (P ＜ 0.01).After adjusting for associated confounding factors,multiple logistic regression analysis showed obesity (OR =3.74,95 ％ CI:1.14-12.23,P ＜ 0.05) and depressive symptoms (OR =5.79,95％ CI:1.76-19.06,P ＜ 0.01) were risk factors for MCR.Conclusions MCR is not uncommon in elderly patients.Obesity and depressive symptoms are closely associated with an increased risk of MCR.

ABSTRACT
Cyclophosphamide (CPA) is the most common alkylating antineoplastic agent, as well as a strong immunosuppressant that is frequently applied to autoimmune diseases and organ transplantation. It is metabolized by cytochrome P450 oxidases (CYPs) to its active metabolite which played a critical role in therapy. CPA has serious and even fatal side effects, and its efficacy and adverse reactions are significantly varied among individuals. In this review, the association of the genetic polymorphisms in the metabolic enzymes and transporters involved in the disposition of CPA with the efficacy and adverse effects of CPA were summarized, thereby providing fundamental reference for further pharmacogenomic study of CPA.
