Atherosclerosis is a chronic inflammatory disease, and vascular smooth muscle cells(VSMC) play a central role in its pathological process. Single-cell RNA sequencing reveals the central role of VSMC in the atherosclerotic microenvironment. Inflammatory factors and oxidized lipids in the atherosclerotic plaque microenvironment affect VSMC phenotype switching and function in various ways, thereby affecting plaque stability. This article summarizes the phenotypic transformation rules, biological behaviors, and interaction mechanisms of VSMC with immune cells in the inflammatory microenvironment of atherosclerosis, and reviews the progress of new anti-inflammatory strategies and models targeting the VSMC-inflammatory axis, in order to provide a theoretical basis and translational direction for the precise treatment of atherosclerosis.

"Sinew prescription correspondence" is the principle of selecting prescriptions for channel sinew diseases. On the basis of the theory of syndrome differentiation and treatment， the pulse manifestation corresponds to the channel sinew syndrome， which can improve the flexibility and standardization of clinical prescriptions. From the perspective of systematic dialectical sphygmology， this paper explains the dialectical relationship between channel sinew theory and pulse body elements， pulse wall elements， pulse elements and blood flow elements， and clarifies the internal relationship between pulse manifestation and prescriptions at the level of channel sinew disease. The prescription is derived from the method， while the method is established with the syndrome， and the prescription is unified by the method. According to the theory of "sinew prescription correspondence"， the treatment ideas of channel sinew diseases were analyzed from the perspective of channel sinew distribution， functional characteristics and structural changes. On this basis， the diagnosis of channel sinew disease and the application of prescriptions are expanded， and the research on the internal treatment and diagnosis mode of "pulse manifestation-channel sinew-zang fu （脏腑）" is prospected， so as to expand the differentiation and treatment methods of channel sinew theory.

Objective·To explore the clinical efficacy and safety of sticky bone[deproteinized porcine bone mineral granules combined with advanced platelet-rich fibrin(A-PRF)and liquid platelet-rich fibrin(L-PRF)]in the repair of unilateral alveolar cleft.Methods·Patients diagnosed with unilateral alveolar cleft who met the inclusion and exclusion criteria were recruited from December 1,2023 to August 31,2024.The patients were randomly divided into 2 groups.The experimental group received sticky bone grafts,and the control group received autologous iliac cancellous bone grafts for alveolar cleft repair.The primary efficacy index was the bone resorption rate at 6 months post-surgery,calculated by measuring the grafted bone volume immediately after surgery and at 6 months using Simplant Pro 17.01 software based on patients'computed tomography data collected before surgery,immediately after surgery,and 6 months post-surgery.Secondary efficacy indices included bone density at 6 months after surgery,the occurrence of postoperative complications in patients,and the scores on the oral health-related quality of life scale.Prism 10 software was used for data analysis,and t-test and Pearson correlation analysis methods were adopted.Results·Seventeen patients with unilateral alveolar cleft were included in the experimental group,and 15 in the control group.The remaining bone volume in the experimental group at 6 months after surgery was more than that in the control group.The bone resorption rate in the experimental group was 33.24%±17.16%,significantly lower than 66.31%±17.98%in the control group(P<0.001).One patient in the experimental group had vestibular mucosal dehiscence accompanied by bone powder discharge 2 weeks after surgery;3 patients in the control group had vestibular mucosal dehiscence accompanied by cancellous bone discharge 1 month after surgery,with one case of grafted bone necrosis 4 months after surgery.The bone density in the experimental group at 6 months after surgery was significantly higher than that in the control group(P<0.001),and the scores on the oral health-related quality of life scale were lower.Conclusion·Compared with iliac cancellous bone,when sticky bone is used in the treatment of patients with unilateral alveolar cleft,it shows a lower bone resorption rate and higher bone density,indicating better osteogenic ability.Fewer number of complications and lower scores on the oral health-related quality of life scale suggest greater safety,thereby supporting its strong potential for clinical promotion and application.

Objective:To explore the training experiences of palliative care nurses participating in a prognosis disclosure workshop based on Kolb's experiential learning model, and to provide references for future educational programs in palliative care nursing.Methods:Using purposive sampling, 11 nurses were recruited who had participated in the "Palliative Care Competency Training Program for Nurses" in Shanghai between March and May 2025 and selected the Third Affiliated Hospital of Naval Medical University as their clinical training site. Semi-structured interviews were conducted, and data were analyzed using Colaizzi's seven-step method.Results:A total of three major themes emerged: a sense of benefit from enhanced competencies; complex emotional experiences; recommendations for course optimisation.Conclusions:Workshops based on Kolb's experiential learning model offer positive value in palliative care education. They effectively improve core competencies such as communication and empathy. However, the emotional experiences of nurses must also be considered, and multifaceted optimizations to the training design are recommended to further enhance training outcomes.

Rice (Oryza sativa L.) is an important food crop. The appearance of lesion mimics in rice leads to phytohormone disorders, which affects rice adaptation to environmental stresses and ultimately reduces the yield and quality. To explore whether the changes in the adaptability of rice lesion-mimic mutants to stressful environments are caused by the disorder of phytohormone metabolism in plants. In this study, we screened an ethyl methane sulfonate-treated population of the japonica cultivar 'Taipei 309' for a mutant with rust-like spots on leaves at the early tillering stage and brown-red spots at maturity and named it rsl1 (rust spotted leaf 1). Compared with the wild type, rsl1 showed decreases in plant height, panicle length, primary branch number, secondary branch number, filled grains per panicle, seed-setting rate, and 1 000-grain weight, and an increase in number of effective panicles. Genetic analysis indicated that rsl1 was controlled by a single recessive nuclear gene. RSL1 was localized between two molecular markers, B7-7 and B7-9, on rice chromosome 7 by map-based cloning. PCR sequencing of the annotated genes in this interval revealed a mutation of C1683A on the eighth exon of SPL5 (LOC_Os07g10390) in rsl1, which resulted in premature termination of protein translation. Exogenous phytohormone treatments showed that rsl1 was less sensitive to salicylic acid (SA), abscisic acid (ABA), and indo-3-acetic acid (IAA) and more sensitive to methyl jasmonate (MeJA) and gibberellin acid (GA) than the wild type. In addition, the survival rate of rsl1 was lower than that of the wild type under salt, alkali, drought, and high temperature stresses, and it was higher than that of the wild type under cold stress. Quantitative real-time polymerase chain reaction (qRT-PCR) results showed that RSL1 was involved in the regulation of ABA, SA, MeJA, IAA, and GA-related genes under abiotic stresses. The present study showed that the RSL1 mutation led to the appearance of lesion mimics and affected the growth, development, and stress resistance of rsl1 under abiotic stresses. The study of the functional mechanism of this gene can provide theoretical guidance for the research on rice stress resistance.

Digital simulation and three-dimensional (3D) printing technology-assisted treatment of mandibular fractures in children has good clinical application value. During the surgery, attention should be paid to the fixation of dentition defects, jawbone development, and the protection of permanent tooth germs. This article reports a case of a 7-year-old male patient with a mandibular chin fracture, treated with digital simulation of fracture reduction and 3D printing of mandible model, along with implantable occlusal splint, then underwent open reduction and internal fixation surgery. After 3 and 6 months, the 3D printed splint and internal fixation titanium plate were removed. The mandibular fracture healed well, without affecting jawbone development, and the tooth germs remained undamaged, the occlusal relationship recovered well. The case suggests the use of computer digital simulation and 3D printing technology facilitates precise reduction of mandibular fractures and reduces the impact on the jawbone and tooth germs, which provids valuable clinical reference.

AIM:To investigate the role of serum high-sensitivity C-reactive protein(hsCRP)in the pathogenesis and progression of diabetic retinopathy(DR)in patients with type 2 diabetes mellitus(T2DM).METHODS:A nested case-control study was conducted involving 187 T2DM patients(187 eyes)who attended at Eye Center, Beijing Tongren Hospital, Capital Medical University from June 2017 to October 2024. Patients were categorized into three groups: the diabetes mellitus(DM)group, non-proliferative DR(NPDR)group, and proliferative DR(PDR)group. Baseline information was collected, including age, sex, duration of DM, and duration of hypertension. All patients underwent fasting biochemical tests and comprehensive ophthalmic examinations.RESULTS: A positive correlation was observed between hsCRP and fasting blood glucose(FBG; P=0.004)and glycated hemoglobin A1c(HbA1c; P=0.048)by Spearman's rank correlation coefficient analysis. After adjusting for confounding factors, multivariable Logistic regression identified hsCRP as a significant risk factor for DR(OR=2.67, 95% CI: 1.19-5.96, P=0.017). CONCLUSION:Serum hsCRP is positively correlated with FBG and HbA1c and can serve as an important predictor of the severity of DR.
