ObjectiveTo explore the effect of elbow-wrist functional orthosis on plantar pressure distribution and balance function in stroke patients with hemiplegia. MethodsFrom June, 2024 to April, 2025, 60 patients with post-stroke hemiplegia were recruited from Huashan Hospital, Fudan University, and Shanghai Hebin Rehabilitation Hospital. They were randomly divided into control group (n = 30) and intervention group (n = 30). The control group received routine neurological rehabilitation, while the intervention group received additional training with an elbow-wrist functional orthosis on the affected side, for eight weeks. Before and after intervention, the Modified Ashworth Scale (MAS) of the elbow joint, plantar pressure symmetry index (SI), plantar contact area and mean plantar pressure were recorded, and balance and mobility were assessed using the Berg Balance Scale (BBS), Timed Up & Go Test (TUGT) and 10-Meter Walk Test (10MWT). ResultsTwo cases dropped out in the control group. After treatment, MAS grades of the elbow joint, forefoot SI, affected side plantar pressure area, BBS scores, TUGT and 10MWT of both groups improved (|Z| > 3.969, |t| > 3.528, P < 0.01), while the hindfoot SI and average pressure of the affected foot improved in the intervention group (∣t∣ > 4.264, P < 0.001). Except for TUGT and 10MWT, the intervention group was superior to the control group (∣Z∣ > 2.030, ∣t∣ > 2.096, P < 0.05). ConclusionThe elbow-wrist functional orthosis can enhance balance function in stroke patients with hemiplegia by reducing upper-limb spasticity, optimizing center-of-gravity distribution, and improving postural control.

Objective To investigate the effect and mechanism of miR-20a-5p on human nephroblastoma cell line WiT49 transplanted tumor in nude mice.Methods The gene expression chip was downloaded from GEO database,and the differential gene miR-20a-5p was obtained by GEO2R.The NF-κB gene was positively correlated with the expression of miR-20a-5p through cBioPortal database.The target gene of miR-20a-5p was predicted to be NFKBIB of the NF-κB transcription factor suppressor protein family by targetscan database,and was verified by dual luciferase assay.Nephroblastoma cell line WiT49 was cultured in vitro and transfected into WiT49 cells with lentiviral vectors constructed with miR-20a-5p mimics and its suppressor gene.Twelve nude mice were randomly divided into three groups:WiT49 model group,WIT49-miR-20a-5p overexpression group and WIT49-miR-20a-5p knockdown group.The tumor mass and volume of each group were detected by tumor formation experiment in nude mice.real time fluorescent quantitative polymerase chain reaction(qRT-PCR)was used to detect the expression of miR-20a-5p,NFKBIB and NF-κB in each group;CCK-8 cell proliferation assay was used to verify the proliferation of tumor cells in each group.Results miR-20a-5p is highly expressed in nephroblastoma and is positively correlated with the expression of NF-κB.miR-20a-5p and NFKBIB have mutual binding sites and binding effects.In the tumor formation experiment of nude mice,the tumor volume and mass of WIT49-miR-20a-5P overexpression group were significantly increased compared with WiT49 model group,and the difference was statistically significant(P<0.05).In the qRT-PCR test,the expressions of miR-20a-5p and NF-κB in the WIT49-miR-20a-5p overexpression group were higher than those in the WiT49 model group,and NFKBIB expression in the WIT49-miR-20a-5p overexpression group was lower than that in the WiT49 model group,with statistical significance(P<0.05).CCK-8 cell proliferation assay showed that the absorbance of WIT49-miR-20a-5p overexpression group at 24 and 48 hours was higher than that of WiT49 model group,and the absorbance of WIT49-miR-20a-5p knockdown group at 24,48 and 72 hours was lower than that of WiT49 model group,and the difference was statistically significant(P<0.05).Conclusion miR-20a-5p may promote the growth of human nephroblastoma cell WiT49 transplanted tumor in nude mice by regulating NFKBIB activation of NF-κB pathway.

Objective To analyse the concept of subjective financial distress in cancer patients.Methods Papers in regarding the subjective financial distress were retrieved from the databases such as China National Knowledge Infrastructure(CNKI),Wangfang Database,PubMed,Cochrane Library,Web of Science,CINAHL,and Embase from the inceptions to 16th October,2022.Walker and Avant's concept analysis was performed to analyse the acquired articles.Results A total of 48 articles were retrieved and included in the study.Walker and Avant's concept analysis showed that the subjective financial distress in the patients was subject to the 3 defining attributes:perceived economic risk,coping behaviours,and negative emotional reactions.The antecedents of this distress included individual factors,disease and treatment factors,and social factors.The consequences of them were the increase in negative health behaviours and poorer quality of life.Conclusions The attributes,antecedents and consequences of subjective financial distress,as identified through the conceptual analysis,can serve as a reference for subsequent researches.In future studies,it would be beneficial by further exploring the connotation by considering China's healthcare system.

Objective To explore the effect of enhanced recovery after surgery(ERAS)in perioperative period of complicated appendicitis in children.Methods A total of 248 children with complicated appendicitis who underwent laparoscopic surgery in Quanzhou Children's Hospital from January 2020 to January 2023 were selected and divided into control group and ERAS group according to random number table method,with 124 cases in each group.Both groups of patients underwent laparoscopic appendectomy.The control group received traditional treatment during perioperative period,while the ERAS group received treatment based on the concept of ERAS.The first postoperative exhaust/defecation time,hospital stay,visual analogue scale(VAS)score,postoperative complications and hospitalization satisfaction were compared between two groups.Results The time of first postoperative exhaust/defecation and hospital stay in ERAS group were significantly shorter than those in control group,total incidence of postoperative complications and postoperative VAS score were significantly lower than those in control group,and hospitalization satisfaction was significantly better than that in control group(P<0.05).Conclusion ERAS implementation during perioperative period of complicated appendicitis in children can promote early postoperative recovery,reduce postoperative pain,reduce the incidence of complications,and improve hospitalization satisfaction,which is worthy of clinical promotion and application.

Objective To investigate the effects of menaquinone-4(MK4)on the activation and function of CD8+T cells.Methods An in vitro culture system for primary mouse CD8+T cells was established by isolating these cells from the spleen using CD8a T cell isolation kit.The isolated CD8+T cells were then incubated and activated in a 96-well plate coated with anti-CD3/CD28 antibodies.The impact of MK4 on the activation and cytokine secretion of CD8+T cells was explored by quantifying the expression levels of CD8+T cell activation receptors and cytokines using flow cytometry.Additionally,the concentrations of these cytokines in the culture supernatant were measured by enzyme-linked immunosorbent assay(ELISA).The influence of MK4 on the anti-tumor function of CD8+T cells was evaluated by co-culturing colorectal cancer MC38 cells of mice with CD8+T cells at different ratios,and the effect of MK4 was assessed by detecting tumor cell apoptosis.Results High-purity primary CD8+T cells of mice(97.5％)were isolated using the magnetic bead,which could be activated by pre-coated CD3/CD28 antibodies and showed proliferation.Compared with the control group,the MK4-treated group exhibited increased expressions of CD25,CD69 and CD44 on CD8+T cells,as well as higher production and secretion levels of interleukin-2(IL-2),interferon-γ(IFN-γ),tumor necrosis factor-α(TNF-α)and granzyme B.In addition,CD8+T cells in the MK4-treated group induced a higher percentage of tumor cell apoptosis(36.7％)compared with the control group(29.1％).Conclusion MK4 can enhance the activation of CD8+T cells and promote anti-tumor functions.

Objective To explore the clinical application value of MRI fat quantification parameter[verte-bral bone marrow fat fraction(FF)]combined with 25-hydroxyvitamin D[25(OH)D]in predicting fracture risk in patients with osteoporosis.Methods A total of 90 patients with osteoporosis who were admitted to the hospital from January 2023 to April 2024 were selected as the subjects.Among them,50 patients with osteoporotic vertebral com-pression fractures were included in the fracture group,and 40 patients without fractures were included in the control group.All patients underwent the iterative decomposition of water and fat with echo asymmetry and least-squares estimation(IDEAL-IQ)method of MRI to measure the FF of each vertebra among L1-5 and the average FF of L1-5.Serum 25(OH)D level was detected by electrochemiluminescence method.FF and serum 25(OH)D levels of the two groups were compared.The correlation of FF,25(OH)D and bone mineral density(BMD)was analyzed.Multi-variate logistic regression analysis was conducted to screen the risk factors for fracture in patients with osteoporosis.Receiver operating characteristic(ROC)curves were used to evaluate the predictive value of FF,25(OH)D,and their combination for fracture in patients with osteoporosis.Results Patients in the fracture group were older than those in the control group.BMD and serum 25(OH)D level were lower than those of the control group(P<0.05).The FF of L2 and average FF of L1-5 in the fracture group were higher than those in the control group(P<0.05).Correlation analysis results showed that the FF of L2 and the average FF of L1-5 were negatively correlated with BMD(P<0.05),while serum 25(OH)D level was positively correlated with BMD(P<0.05).Multivariate logistic regression analysis showed that age and FF of L2 were independent risk factors for fracture in patients with osteoporo-sis,while BMD and 25(OH)D were protective factors(P<0.05).ROC curves indicated that the AUC values of FF of L2 and 25(OH)D for predicting fracture were 0.714(95%CI:0.606～0.822)and 0.774(95%CI:0.672～0.876).The AUC of joint prediction was 0.923(95%CI:0.867～0.978),which was significantly larger than that of separate prediction(P<0.05).Conclusions FF of L2 and serum 25(OH)D are related to fracture in patients with osteopo-rosis.Age and BMD are factors influencing the occurrence of fracture in patients with osteoporosis.FF of L2 and 25(OH)D have certain predictive value for fracture risk in patients with osteoporosis,and combined detection of the two can improve predictive efficiency.

Small nucleolar RNAs (snoRNAs), a type of non-coding RNAs ubiquitous in eukaryotes, can be categorized into two types based on structural characteristics: box C/D snoRNAs and box H/ACA snoRNAs, which mediate the RNA modification of 2′-O-methylation and pseudouridylation, respectively. Recent studies have found that snoRNAs also affect the alternative splicing of mRNA precursors (pre-mRNA), mediate gene silencing by generating miRNA, and interact with proteins to regulate their functional activity. The process of DNA damage and repair always serves as a pivotal biological basis in research on the biological effects of ionizing radiation. Currently, there are rather limited studies on the role of snoRNAs in ionizing radiation-induced DNA damage. Thus, this paper reviews the biological functions of snoRNAs and their potential role in the regulatory repair of ionizing radiation-induced DNA damage, with a view to providing new ideas for exploring the function and mechanism of snoRNAs.
