RESUMO
PURPOSE: Many epidemiological studies have reported that elder abuse and neglect were prevalent in rural areas. However, none of them has synthesized the literature in this field. Therefore, we aimed to estimate the overall prevalence of elder abuse and neglect in rural areas through a systematic review and meta-analysis. METHODS: PubMed, EMBASE, Web of Science, and Cochrane Library were systematically searched to identify eligible articles, with no language restrictions. Statistical analyses were conducted using Review Manager software (version 5.3). Meta-analyses and sensitivity analysis were performed using a random-effects model. All results were reported as the pooled prevalence of elder and neglect with their 95% confidence intervals (CIs). The quality of the included studies was evaluated by strengthening the reporting of observational studies in epidemiology (STROBE) checklist. Potential publication bias was assessed by the funnel plot. RESULTS: 13 cross-sectional studies involving 10,313 participants were eligible. The prevalence of elder abuse and neglect ranged from 4.5 to 61.7% across the rural areas, and pooled prevalence estimate was 33% (95% CI 23-43). The prevalence of physical abuse was estimated at 7% (95% CI 5-9), financial abuse at 5% (95% CI 4-7), psychological/emotional abuse at 17% (95% CI 11-23), and neglect at 26% (95% CI 17-35). There was significant heterogeneity among the included studies. Stratified analyses revealed that sampling design was part of the heterogeneity source. WHO regions, gender, countries' income classification, and study quality could not explain the potential reasons for heterogeneity. CONCLUSIONS: The pooled prevalence of elder abuse and neglect was relatively high in rural areas. Early and targeted screening and prevention are needed. There is an urgent need for high quality studies using agreed definition of elder abuse and neglect to protect the potential high risk populations.

OBJECTIVE: To investigate the mechanism of hematopoietic reconstruction in mice treated with Danggui Buxue Decoction (DBD) combined with the muscle-derived stem cell transplantation (MDSCT). METHODS: Female Kunming mice were randomly divided into the 6 groups: irradiation model, the bone marrow transplantation, the MDSC transplantation, the DBD 1 (4.5 g/kg), 2 (13.5 g/kg), and 3 (22.5 g/kg) + MDSC transplantation. After a week of oral administration of normal saline or different doses of DBD, The mice were exposied to 8 Gy 137Cs γ ray and were followed by bone marrow or MDSC transplantation. The expression levels of Notch1, Jagged1 and Hes1 in bone marrow, thymus and spleen were measured at 3 and 8 weeks after irradiation and transplantation. RESULTS: In the bone marrow, 3 weeks after above-mentioned treatment, the expression of Notch1 mRNA increased obviously and the expression of Jagged1, Hes1 mRNA decreased obviously in each intervention group, compared with the irradiation model group. 8th week after treatment, the expression of Notch1 mRNA decreased obviously in each intervention group, the Jagged1 mRNA expression decreased obviously except the bone marrow group, and Hes1 mRNA expression increased (Pï¼0.05) in each intervention group. 3 weeks after treatment, compared with the irradiation model group, the expression of Notch1 mRNA in the thymocytes increased only in DBD1+MDSC group, Jagged1, Hes1 mRNA was increased in the MDSC transplantation group and the DBD1ã2+MDSC group. 8th week after treatment, the expression of Notch1, Jagged1 mRNA expression decreased in each intervention group, the expression of Hes1 mRNA increased obviously in the MDSC transplantation group and the DBD1ã2+MDSC group (Pï¼0.05). In the spleen, 3 weeks after treatment, the expression of Notch1, Jagged1 mRNA in the spleen of each intervention group decreased obviously, compared with the irradiation model group. The expression of Jagged1, Hes1 mRNA in each intervention group were increased obviously 8th week after treatment (Pï¼0.05). CONCLUSION: MDSC transplantation after pretreatment of DBD can improve the hematopoietic reconstitution in mice with lethal dose radiation damage. Notch1ãJagged1 and Hes1 play different roles in this process, but the concrete mechanism needs to be further studied.
