Objective To explore the effect of feeding training based on solution-focused brief therapy on swallowing function in stroke patients with dysphagia.Methods Patients with dysphagia after stroke who were hospitalized in Wuxi Central Rehabilitation Hospital from January 2021 to February 2022 were selected in this study.They were divided into control group and observation group according to the time of admission,with 55 patients in each group.The control group received routine nursing.The observation group received routine nursing and feeding training based on solution-focused brief therapy.The negative emotions,swallowing function and quality of life of patients were evaluated before and after nursing intervention.Results There was no significant difference in the scores of anxiety,depression,water drinking test,or swallowing scale between the two groups before nursing intervention(P>0.05).The scores of anxiety,depression,and water drinking test in the observation group were significantly lower than those in the control group after nursing intervention(P<0.05),and the scores of the quality of life in the observation group were significantly higher than those in the control group(P<0.05).Conclusion Feeding training based on the solution-focused brief therapy can alleviate anxiety and depression,and improve swallowing function,the recovery and the quality of life for stroke patients with dysphagia.

Objective To establish evaluation indicators of nutrition care ability for carrying out oral feeding by caregivers of patients with post-stroke dysphagia (PSD) so as to provide references for nursing staff in evaluation of the nutritional care ability of caregivers and for the targeted health education. Methods Based on the caregiver skill model proposed by Farran et al,literature review and analysis,semi-structured interview,Delphi expert inquiry,analysis with the Analytic Hierarchy Process and pre-survey were conducted to establish a pool of evaluation indicators for nutrition care ability in carrying out oral feeding by caregivers of patients with PSD and to determine the weights of indicators. Results The two rounds of inquiry questionnaires achieved effective response rates of 90.00％ and 100.00％,respectively. The expert authority coefficients were at 0.869 and 0.910,and the coefficients of variation ranged 0.035 to 0.162 and 0.025 to 0.078 for the first and second rounds. The Kendall coordination coefficients were between 0.205 and 0.276 for the first round and between 0.278 and 0.364 for the second round (P<0.01). Based on expert consultations,the evaluation indicators were finalised,comprising 6 primary indicators and 38 secondary indicators,with consistency coefficients of each level indicator is less than 0.05. The primary indicators consisted of the knowledge of oral feeding nutrition care,attitude of oral feeding nutrition care,care skills,personal qualities of the caregiver,management of own emotions,and management of family and social resources. Conclusion The evaluation indicators for nutrition care ability to carry out oral feeding by caregivers of patients with PSD has been established. They are scientifically sound and rational,with strong practicality,and are able to provide a reference for nursing staff in evaluation of the nutrition care ability of caregivers and the health education.

BACKGROUND: The formation of an inhibitory inflammatory microenvironment after spinal cord injury (SCI) remains a great challenge for nerve regeneration. The poor local microenvironment exacerbates nerve cell death; therefore, the reconstruction of a favorable microenvironment through small-molecule drugs is a promising strategy for promoting nerve regeneration. METHODS: In the present study, we synthesized curcumin-loaded micelle nanoparticles (Cur-NPs) to increase curcumin bioavailability and analyzed the physical and chemical properties of Cur-NPs by characterization experiments. We established an in vivo SCI model in rats and examined the ability of hind limb motor recovery using Basso–Beattie– Bresnahan scoring and hind limb trajectory assays. We also analyzed neural regeneration after SCI using immunofluorescence staining. RESULTS: The nanoparticles achieved the intelligent responsive release of curcumin while improving curcumin bioavailability. Most importantly, the released curcumin attenuated local inflammation by modulating the polarization of macrophages from an M1 pro-inflammatory phenotype to an M2 anti-inflammatory phenotype. M2-type macrophages can promote cell differentiation, proliferation, matrix secretion, and reorganization by secreting or expressing pro-repair cytokines to reduce the inflammatory response. The enhanced inflammatory microenvironment supported neuronal regeneration, nerve remyelination, and reduced scar formation. These effects facilitated functional repair in rats, mainly in the form of improved hindlimb movements. CONCLUSION Here, we synthesized pH/temperature dual-sensitive Cur-NPs. While improving the bioavailability of the drug, they were also able to achieve a smart responsive release in the inflammatory microenvironment that develops after SCI. The Cur-NPs promoted the regeneration and functional recovery of nerves after SCI through anti-inflammatory effects, providing a promising strategy for the repair of SCIs.

BACKGROUND: Intervertebral disk (IVD) degeneration, which can cause lower back pain, is a major predisposing factor for disability and can be managed through multiple approaches. However, there is no satisfactory strategy currently available to reconstruct and recover the natural properties of IVDs after degeneration. As tissue engineering develops, scaffolds with embedded cell cultures have proved critical for the successful regeneration of IVDs. METHODS: In this study, an integrated scaffold for IVD replacement was developed. Through scanning electron microscopy and other mechanical measurements, we characterized the physical properties of different hydrogels. In addition, we simulated the physiological structure of natural IVDs. Nucleus pulposus (NP) cells and annulus fibrosusderived stem cells (AFSCs) were seeded in gelatin methacrylate (GelMA) hydrogel at different concentrations to evaluate cell viability and matrix expression. RESULTS: It was found that different concentrations of GelMA hydrogel can provide a suitable environment for cell survival. However, hydrogels with different mechanical properties influence cell adhesion and extracellular matrix component type I collagen, type II collagen, and aggrecan expression. CONCLUSION This tissue-engineered IVD implant had a similar structure and function as the native IVD, with the inner area mimicking the NP tissue and the outer area mimicking the stratified annulus fibrosus tissue. The new integrated scaffold demonstrated a good simulation of disc structure. The preparation of efficient and regeneration-promoting tissueengineered scaffolds is an important issue that needs to be explored in the future. It is hoped that this work will provide new ideas and methods for the further construction of functional tissue replacement discs.
