With the continuous intensification of aging， chronic diseases among the elderly have become a widely concerned public health issue. In the terminal stage， they often lose the ability to express their medical care wishes autonomously， leading to a disconnect between medical decision-making and the actual needs of the patients and increasing their physical and psychological suffering. With the rapid aging process in China， the incidence of chronic diseases in the elderly is continuously rising， which has become a serious public health problem. Studies have shown that advance care planning （ACP） has achieved remarkable results in maintaining the dignity of life for terminal chronic disease patients， improving patients’ quality of life， as well as alleviating the physical， mental， and economic burdens on their families. Therefore， the implementation of ACP is crucial for elderly patients with chronic diseases. This paper reviewed the concept of ACP， as well as application effects， challenges and limitations， and corresponding recommendations and countermeasures of ACP in elderly patients with chronic diseases， with a view to providing a solid theoretical and practical basis for the application of ACP in elderly population with chronic diseases in China.

BACKGROUND: Neoadjuvant chemoradiotherapy followed by radical surgery has been a common practice for patients with locally advanced rectal cancer, but the response rate varies among patients. This study aimed to develop a ResNet-Vision Transformer based magnetic resonance imaging (MRI)-endoscopy fusion model to precisely predict treatment response and provide personalized treatment. METHODS: In this multicenter study, 366 eligible patients who had undergone neoadjuvant chemoradiotherapy followed by radical surgery at eight Chinese tertiary hospitals between January 2017 and June 2024 were recruited, with 2928 pretreatment colonic endoscopic images and 366 pelvic MRI images. An MRI-endoscopy fusion model was constructed based on the ResNet backbone and Transformer network using pretreatment MRI and endoscopic images. Treatment response was defined as good response or non-good response based on the tumor regression grade. The Delong test and the Hanley-McNeil test were utilized to compare prediction performance among different models and different subgroups, respectively. The predictive performance of the MRI-endoscopy fusion model was comprehensively validated in the test sets and was further compared to that of the single-modal MRI model and single-modal endoscopy model. RESULTS: The MRI-endoscopy fusion model demonstrated favorable prediction performance. In the internal validation set, the area under the curve (AUC) and accuracy were 0.852 (95% confidence interval [CI]: 0.744-0.940) and 0.737 (95% CI: 0.712-0.844), respectively. Moreover, the AUC and accuracy reached 0.769 (95% CI: 0.678-0.861) and 0.729 (95% CI: 0.628-0.821), respectively, in the external test set. In addition, the MRI-endoscopy fusion model outperformed the single-modal MRI model (AUC: 0.692 [95% CI: 0.609-0.783], accuracy: 0.659 [95% CI: 0.565-0.775]) and the single-modal endoscopy model (AUC: 0.720 [95% CI: 0.617-0.823], accuracy: 0.713 [95% CI: 0.612-0.809]) in the external test set. CONCLUSION The MRI-endoscopy fusion model based on ResNet-Vision Transformer achieved favorable performance in predicting treatment response to neoadjuvant chemoradiotherapy and holds tremendous potential for enabling personalized treatment regimens for locally advanced rectal cancer patients.

Objective To explore the immune mechanism of Tibetan medicine Twelve Flavors Yishou San in intervening with acute lung injury.Methods Construct a lipopolysaccharide(LPS)-induced acute lung injury rat model and treated it with Twelve Flavors Yishou San.The intervention effect of Twelve Flavors Yishou San on LPS induced acute lung injury was determined through lung pathological sections and blood gas analysis.Enzyme linked immunosorbent assay(ELISA)was used to detect the expression of pro-inflammatory cytokine tumor necrosis factor-α(TNF-α)and anti-inflammatory cytokine interleukin(IL)-10 in rat's bronchoalveolar lavage fluid.Flow cytometry was used to detect changes in immune cells in rat's bronchoalveolar lavage fluid,lungs,spleen and peripheral blood.Results LPS successfully induced an acute lung injury model in rats,and Twelve Flavors Yishou San could alleviate the exudation of inflammatory cells,elevated oxygen partial pressure in LPS induced acute lung injury to varying degrees.The ELISA results of rat bronchoalveolar lavage fluid showed that compared with normal control group,the TNF-α level in the bronchoalveolar lavage fluid of rats with acute lung injury was increased and the IL-10 level was decreased,while the Twelve Flavors Yishou San could alleviate this effect.The results of flow cytometry showed that Twelve Flavors Yishou San could significantly reduce neutrophil infiltration in rat bronchoalveolar lavage fluid,but had no significant effect on macrophages and adaptive immune response.Conclusion Twelve Flavors Yishou San can alleviate LPS induced acute lung injury by inhibiting neutrophil infiltration,providing an important experimental basis for fully understanding the therapeutic mechanism of Twelve Flavors Yishou San.

BACKGROUND: The effect of intra-operative chemotherapy (IOC) on the long-term survival of patients with colorectal cancer (CRC) remains unclear. In this study, we evaluated the independent effect of intra-operative infusion of 5-fluorouracil in combination with calcium folinate on the survival of CRC patients following radical resection. METHODS: 1820 patients were recruited, and 1263 received IOC and 557 did not. Clinical and demographic data were collected, including overall survival (OS), clinicopathological features, and treatment strategies. Risk factors for IOC-related deaths were identified using multivariate Cox proportional hazards models. A regression model was developed to analyze the independent effects of IOC. RESULTS: Proportional hazard regression analysis showed that IOC (hazard ratio [HR]=0.53, 95% confidence intervals [CI] [0.43, 0.65], P  < 0.001) was a protective factor for the survival of patients. The mean overall survival time in IOC group was 82.50 (95% CI [80.52, 84.49]) months, and 71.21 (95% CI [67.92, 74.50]) months in non-IOC group. The OS in IOC-treated patients were significantly higher than non-IOC-treated patients ( P  < 0.001, log-rank test). Further analysis revealed that IOC decreased the risk of death in patients with CRC in a non-adjusted model (HR=0.53, 95% CI [0.43, 0.65], P  < 0.001), model 2 (adjusted for age and gender, HR=0.52, 95% CI [0.43, 0.64], P  < 0.001), and model 3 (adjusted for all factors, 95% CI 0.71 [0.55, 0.90], P  = 0.006). The subgroup analysis showed that the HR for the effect of IOC on survival was lower in patients with stage II (HR = 0.46, 95% CI [0.31, 0.67]) or III disease (HR=0.59, 95% CI [0.45, 0.76]), regardless of pre-operative radiotherapy (HR=0.55, 95% CI [0.45, 0.68]) or pre-operative chemotherapy (HR=0.54, 95% CI [0.44, 0.66]). CONCLUSIONS: IOC is an independent factor that influences the survival of CRC patients. It improved the OS of patients with stages II and III CRC after radical surgery.
