Objective To explore the dual coping experience of nursing dependence among middle-aged and young patients with enterostomy and their primary caregivers from the perspective of family resilience,in order to provide evidence for improving the experience of nursing dependence and promoting family resilience.Methods Us-ing the phenomenological research method in qualitative research,18 young and middle-aged enterostomy patients and their primary caregivers were selected for semi-structured interviews with purpose sampling method,and the in-terview data were analyzed by content analysis method.Results A total of 4 themes and 8 sub-themes were ex-tracted.Theme 1:heavy dependence-elastic fatigue-weak resilience(patients avoid stomas,depression,caregivers help-lessly accepting;patients role reinforcement,excessive dependence,caregivers exhaustion);theme 2:moderate depen-dence-elastic adjustment-strong resilience trend(active exploration,mutual understanding,perceived support;focus ad-justment,mutual dependence,positive relationship);theme 3:mild dependence-elastic space-strong resilience(self-con-trollable feeling,quick adaptation,mutual growth;facing calmly,cherishing life,reshaping value);theme 4:no depen-dence-gradual loss of elasticity-weak resilience trend(refusal to seek help,self isolation,relationship cracks;frustration in seeking help,self-protection,relationship alienation).In this article,we proposed a preliminary family resilience model for patients with enterostomy.Conclusion The dual coping and family resilience of the patients with en-terostomy and their primary caregivers are different and dynamic.Family-centered support should be applied to strengthen the positive coping and improve the level of family resilience.In addition,this study also tried to pro-pose a family resilience model for patients with enterostomy based on nursing dependence,in order to enrich the connotation of family resilience.

Objective By systematically reviewing the development of policies related to rural doctors and their evolution patterns,and by quantitatively analyzing the policy tools and their effectiveness levels,it aim to provide a strategic basis and reference for the high-quality development of China's rural doctor workforce.Methods 60 policies related to rural doctors enacted at the national level from March 2009 to May 2024 were collected,and a three-dimensional analysis framework based on"policy tool-policy period-policy effectiveness"was adopted to analyse the development of rural doctors in China.Results Among the 245 coded policy instruments,demand-type policy instruments accounted for the highest proportion (38.38％),followed by supply-type (31.02％) and environment-type is the least (30.61％).The types of policies are mainly circular,and the number of policies issued fluctuates significantly,with the number of policies issued during the period of high-quality development being the highest in the four periods,and the policies issued during the period of deepening and consolidation being the most specific.Conclusion It is necessary to scientifically grasp the law of evolution of policy orientation and the trend of evolution of policy instruments,rationally adjust the internal structure of policy instruments,and enhance the relevance and synergy of the policy system in order to improve the cohesion of policy effectiveness.

Objective:To investigate the adjunctive diagnostic value of retinal imaging structural parameters combined with apolipoprotein E (ApoE) gene polymorphisms for Alzheimer′s disease (AD).Methods:It was a case-control study, 71 confirmed AD patients who attended the Department of Neurology in Sichuan Provincial People′s Hospital from May 2023 to June 2024 and 156 healthy medical checkups who participated in medical checkups in the Health Management Center were continuously with convenience sampling method; the subjects were included as the AD case group and healthy control group, respectively. Optical coherence tomography (OCT) was used to measure the structural parameters of retinal imaging such as the thickness of the retinal nerve fiber layer (RNFL) and the retinal nerve fiber layer-inner plexiform layer (RNFL-IPL) in the study subjects. Information on demographic characteristics and disease history of the study participants were collected through a questionnaire, and venous blood was collected to test for ApoE gene polymorphisms. The retinal imaging structural parameters, ApoE gene polymorphisms and other related indicators were included in a multifactorial logistic regression model to analyze the main factors affecting the risk of AD. Based on the results of the multifactorial analysis, the receiver operating characteristic (ROC) curves were plotted and the areas under the curve (AUC) were calculated to evaluate the efficacy of different models in the adjunctive diagnosis of AD.Results:Of the 227 study subjects included in the analysis, 153 were females and 74 were males; there were 71 cases in the AD case group with a mean age of (66.73±8.83) years, and there were 156 subjects in the healthy control group with an average age of (61.95±8.21) years. Educational attainment of elementary school and below ( OR=4.683, 95% CI: 2.133-10.282), living visual acuity<0.5 ( OR=2.716, 95% CI: 1.12-6.583), and carrying ≥1 ApoE ε4 genes ( OR=5.331, 95% CI: 2.309-11.891) were positively correlated with the risk of AD. RNFL thickening ( OR=0.923, 95% CI: 0.854-0.998) was negatively associated with the risk of AD (all P<0.05). The AD risk assessment model (Model 4), which included fundus imaging features and ApoE gene polymorphisms, had the highest predictive efficacy (AUC=0.857, P<0.001). Conclusion:Retinal imaging structural parameters differ significantly between AD patients and healthy examinees, and a risk assessment model combining retinal imaging structural parameters and ApoE gene polymorphisms has high predictive value and is expected to serve as an auxiliary diagnostic tool for AD.

How to effectively reduce the size of infant pose estimation network models is a key issue restricting the"home-use"of infant pose estimation technology. Therefore,a lightweight method for infant pose estimation in home scenarios is proposed. The method takes the lightweight network MobileNetV3 as the encoding backbone and utilizesa PixelShuffle up-sampling module in the decoder for reducing the quantity of model parameters. Meanwhile,coordinate attention mechanism is used to better capture location information and channel feature information,highlighting the feature information of small targets and occluded human keypoints. Besides,the parallel cross-correlation convolution is further modified to enhance the capability of feature information extraction. The method's performance is verified on the general pose estimation dataset (COCO) and the dedicated infant pose estimation dataset (SyRIP). The results show that,with a calculation volume (GFLOPs) of only 0.96,the method achieves average accuracies of 73.5％ and 91.0％ on COCO and SyRIP datasets,respectively,proving that it can significantly reduce the quantity of model parameters and calculation volume without sacrificing pose estimation accuracy. The proposed lightweight estimation model is expected to be deployed on home appliances such as smart terminals,thereby realizing intelligent estimation of abnormal infant poses in home scenarios.
