ObjectiveTo systematically synthesize the illness experiences and unmet needs of patients with stroke during the rehabilitation phase. MethodsQualitative studies focusing on the illness experiences and needs of stroke patients in the rehabilitation period were retrieved from the databases of Cochrane Library, PubMed, Embase, Web of Science, CINAHL, CNKI, CBM, Wanfang data and VIP. The search timeframe was from database inception to December, 2024. Methodological quality was evaluated using the Joanna Briggs Institute Qualitative Assessment and Review Instrument. A meta-synthesis method was adopted to categorize and integrate the findings. ResultsA total of ten studies were included. Forty-nine themes were extracted and further grouped into ten categories, which were finally integrated into three overarching themes: negative illness perceptions, multifaceted rehabilitation motivations and unmet multidimensional needs. ConclusionPatients with stroke undergo complex physical and psychological experiences during rehabilitation and present diverse and multidimensional needs.

Myofascial trigger points， as hyperirritable spots within taut bands of skeletal muscle， can induce local or referred pain， and show a high degree of similarity to acupoints in traditional Chinese medicine （TCM）， particularly the so-called sinew knot lesion point. From the perspective of channel sinew theory， and by examining the correlations of myofascial trigger points with acupoints and channel sinew disorders， this study aims to compare the similarities and differences between MTrPs and sinew knot lesion points in terms of pathological mechanisms， needling analgesic mechanisms， and therapeutic approaches. The goal is to deepen the understanding of MTrPs and dry needling， and provide a modern scientific perspective on channel sinew theory and the sinew knot lesion point.

ObjectiveTo construct an interleukin-9 （Il9） gene knockout mouse model on a C57BL/6N background， establish a reliable genotyping method， and provide a standardized animal model for investigating Il9-related immune mechanisms and diseases. MethodsIl9 knockout mouse strain （C57BL/6N-Il9^em1Cya） was generated using conventional gene knockout technology. The method for DNA extraction from mouse tails was optimized to ensure template quality. Two sets of specific primers （F1/R1 and F1/R2） were designed to amplify target fragments by PCR， and mouse genotypes were determined by agarose gel electrophoresis. Specifically， primer pair F1/R1 targeted the knockout sequence with an expected product of 465 bp， while F1/R2 targeted the wild-type sequence with an expected product of 703 bp. Subsequently， Western blot was performed to verify the knockout efficiency of Il9 in primary immune cells and key organs of the offspring mice， and flow cytometry was used to assess the effects of Il9 deficiency on the function of the immune system in major immune cell populations. ResultsIl9 knockout mice were successfully bred and genotyped. PCR identification showed that homozygous mice （-/-） exhibited only a 465 bp band， wild-type mice （+/+） displayed only a 703 bp band， and heterozygous mice （+/-） showed both bands simultaneously. Meanwhile， Western blot analysis revealed significantly decreased IL-9 expression in various organs of the offspring mice （P<0.001）. Flow cytometric results demonstrated that Il9 deficiency exerted no obvious effects on the proportions of peripheral blood lymphocytes， splenic lymphocytes， and peritoneal macrophages. ConclusionAn Il9 gene knockout mouse model on a C57BL/6N background is successfully constructed. The established PCR genotyping system is highly efficient and accurate， which can effectively distinguish mice of different genotypes. This model provides a stable and reliable experimental basis for subsequent functional studies of Il9 and exploration of the mechanisms underlying Il9-related diseases.

ObjectiveTo construct a chimeric antigen receptor macrophage （CAR-M） targeting interleukin-13 receptor α （IL-13Rα） and intracellular domain integration， which can double activate the signal adaptor protein OX40L of macrophages and T cells. MethodsThe CAR molecule targeting IL-13Rα （IL-13Rα-OX40L-CAR） with OX40L as the intracellular signal domain was designed and synthesized， and it was cloned into the adenovirus expression vector. After THP-1 cells were induced to differentiate into macrophages （THP-1-M） by phorbol ester， the cells were infected with recombinant adenovirus to construct THP-1 macrophages stably expressing green fluorescent protein （GFP） labeled anti-IL-13RαCAR. The expression efficiency of CAR molecules was monitored by flow cytometry. The empty vector group was used as the negative control， the CD3ζ group was used as the positive control， and the CD3ζ-OX40L group was used as the experimental group. The phagocytic function of macrophages in each group on IL-13Rα high expression glioma cells （U251） and low expression glioma cells （T98G） was detected by in vitro co-culture experiments. ResultsCAR adenovirus was efficiently transfected into THP-1-M to obtain anti-IL-13RαCAR-M. After co-cultured with glioma cells with different expression levels of IL-13Rα， the results of flow cytometry showed that there was no significant difference among the three groups for T98G cells with low expression of IL-13Rα. After co-culture with U251 cells with high expression of IL-13Rα， the CD3ζ group showed enhanced phagocytosis compared with the empty vector group （P<0.05）. Compared with the CD3ζ group， the phagocytosis ability of the CD3ζ-OX40L group was further enhanced （P<0.05）. ConclusionAnti-IL13Rα- OX40L-CAR-M is successfully constructed by constructing IL-13Rα-OX40L-CAR adenovirus and transfecting PMA-induced differentiated THP-1-M. It can engulf glioma cells with high expression of IL-13Rα by specific targeting， and shows activation of intracellular domain superior to traditional CD3ζ.

Objective: To evaluate the feasibility of dynamic contrast-enhanced MRI (DCE-MRI) in differentiating tumor deposits (TDs) from metastatic lymph nodes (MLNs) in rectal cancer. Materials and Methods: A retrospective analysis was conducted on 70 patients with rectal cancer, including 168 lesions (70 TDs and 98 MLNs confirmed by histopathology), who underwent pretreatment MRI and subsequent surgery between March 2019 and December 2022. The morphological characteristics of TDs and MLNs, along with quantitative parameters derived from DCE-MRI (K trans , kep, and v e) and DWI (ADCmin, ADCmax, and ADCmean), were analyzed and compared between the two groups.Multivariable binary logistic regression and receiver operating characteristic (ROC) curve analyses were performed to assess the diagnostic performance of significant individual quantitative parameters and combined parameters in distinguishing TDs from MLNs. Results: All morphological features, including size, shape, border, and signal intensity, as well as all DCE-MRI parameters showed significant differences between TDs and MLNs (all P < 0.05). However, ADC values did not demonstrate significant differences (all P > 0.05). Among the single quantitative parameters, v e had the highest diagnostic accuracy, with an area under the ROC curve (AUC) of 0.772 for distinguishing TDs from MLNs. A multivariable logistic regression model incorporating short axis, border, v e, and ADC mean improved diagnostic performance, achieving an AUC of 0.833 (P = 0.027). Conclusion The combination of morphological features, DCE-MRI parameters, and ADC values can effectively aid in the preoperative differentiation of TDs from MLNs in rectal cancer.
