Objective To investigate the clinical significance and potential mechanism of NAT10 in hepatocellular carcinoma.Meth-ods A total of 50 normal and 374 tumor samples were obtained based on The Cancer Genome Atlas(TCGA),and the data were pro-cessed by R 4.2.1.Results The expression of NAT10 in tumor samples was significantly higher than that in normal samples(P＜0.001).Compared with patients with low expression of NAT10,patients with high expression of NAT10had worse prognosis(P＜0.001).Logistic regression analysis showed that high NAT10 expression was associated with adverse clinical prognostic factors,and pa-tients with high NAT10 expression were more likely to progress to the advanced stage.Gene set enrichment analysis(GSEA)results showed that the genes related to heterobiotic metabolism,blood coagulation and fatty acid metabolism were differentially enriched in the samples with high expression of NAT10.The protein interaction analysis results showed that NAT10may interact with genes such as IGF2,SST,MUC2,CHGA,AGR2,etc.Conclusion NAT10 is highly expressed in hepatocellular carcinoma,and the expression level is cor-related with the clinical characteristics and survival rate of patients with hepatocellular carcinoma.NAT10may be a potential molecular bio-marker for hepatocellular carcinoma prognosis.

Objective To evaluate the efficacy of loose-leaf textbooks in nursing risk education for nursing interns.Methods A random number table was used to divide 120 nursing interns in the geriatric oncology department into intervention and control groups,with 60 in each group.The control group received standard clinical nursing instruction,while the intervention group was taught using loose-leaf teaching materials in addition to standard clinical instruction.Occupational risk cognition,pa-tient safety perception,theoretical scores,clinical skills scores,and teaching satisfaction were compared between the two groups.Results The intervention group showed significantly higher scores in occupational risk cognition,patient safety perception,theo-retical achievement,clinical skills achievement,and teaching satisfaction compared to the control group(P＜0.05).Conclu-sion Loose-leaf textbooks enhance nursing interns' learning of occupational risks,improve patient safety perception,boost theo-retical and clinical skills performance,and increase teaching satisfaction.

Depression and circadian rhythms exhibit bidirectional interactions,suggesting a close association with the biological clock system.The biological clock in the suprachiasmatic nucleus of the hypothalamus is regulated by circadian genes.Recent clinical and basic research has revealed multifaceted associations between depression and circadian genes.For instance,significant phase abnormalities in BMAL1,PER2,and PER3 were detected in brain tissue from depressed patients,while plasma levels of CRY1,ARNTL,and PER1 proteins showed marked reduction,demonstrating good diagnostic value.Mice with CLOCK and BMAL1 knockouts exhibited depression-like behaviors.Single nucleotide polymorphisms(SNPs)in genes such as PER1 and PER3 directly influence depression susceptibility.Methylation levels of BMAL1,PER3,and CLOCK genes correlate closely with depressive symptoms.Antidepressant mechanisms like ketamine exert their effects by downregulating PER2 and other genes.This review summarizes the differential expression patterns of circadian clock genes in depression and associated therapeutic approaches,aiming to provide new theoretical foundations for precision diagnosis and personalized treatment strategies for depression.

Aim To explore the effect and mechanism of annexin A1 mimic peptide Ac2-26 on ferroptosis in hu-man umbilical vein endothelial cells(HUVEC).Methods Induction of HUVEC ferroptosis was achieved by the clas-sical ferroptosis agonist RSL3,with subsequent intervention by the annexin A1 mimtic peptide Ac2-26.The cell number and viability were detected by CCK-8 kit,the levels of malondialdehyde(MDA)and glutathione(GSH)were detected by ELISA,the expression of ferroptosis-related molecules and adhesion molecules was detected by Western blot,the lipid re-active oxygen species(ROS)levels were detected by C11-BODIPY fluorescent probe,and the mitochondrial reactive oxy-gen species(mtROS)levels were detected by MitoSOX probe.FeRhoNOX-1 fluorescent probe was used to detect intra-cellular Fe2+content,perspective microscopy was used to observe mitochondrial morphology,JC-1 fluorescent probe was used to detect mitochondrial membrane potential,kit was used to detect ATP levels,the Scratch assay was used to detect cell migration ability,and nitrate reductase assay was used to detect nitric oxide(NO)level.Results Ac2-26 inhibi-ted RSL3-induced decrease in HUVEC viability,up-regulated the expression of suppressor of ferroptosis proteolytic carrier family 7 member 11(SLC7A11),GPX4,and ferritin heavy chain 1(FTH1),increased the GSH content,decreased the MDA content,reduced the generation of intracellular lipid ROS,and decreased the intracellular Fe2+aggregation(P＜0.05 or P＜0.01);Ac2-26 inhibited RSL3-induced damage to HUVEC mitochondrial morphology and function,up-regulated ATP content(P＜0.05)and mitochondrial membrane potential(P＜0.001);Ac2-26 inhibited RSL3-induced decrease in HUVEC migratory ability,up-regulated NO levels,inhibited intercellular adhesion molecule-1(ICAM-1)and interleukin-1β(IL-1β)protein expression(P＜0.05 or P＜0.01).Conclusion Ac2-26 inhibits RSL3-induced ferroptosis in HUVEC and maintains mitochondrial morphology and function,as well as HUVEC function.

Objective:To investigate the prognostic effect of femoral resection on patients with soft tissue sarcoma of the thigh with cortical bone involvement.Methods:This retrospective study included patients with soft tissue sarcoma of the thigh diagnosed and treated in the Second Affiliated Hospital of Zhejiang University School of Medicine from January 2014 to December 2021. Patients were divided into two groups based on whether femoral resection and reconstruction were performed with 20 in the resection group and 86 in the non-resection group. Propensity score matching (PSM) was used to control confounding variables. Overall Survival, recurrence free survival, metastasis free survival, and postoperative functional outcomes were compared between groups before and after PSM. Cox proportional hazards regression was used to identify risk factors for death, recurrence, and metastasis.Results:Before PSM, the 5-year overall survival (OS) and recurrence-free survival (RFS) rates were 46.7% and 36.7% in the resection group, compared to 69.7% and 60.3% in the non-resection group without significant differences ( P>0.05). However, the 5-year metastasis-free survival (MFS) rate was significantly lower in the resection group (40.0%) compared to the non-resection group (73.1%) ( P=0.021). After PSM, the 5-year OS, RFS, and MFS in the resection group were 46.7%, 36.7%, and 35.9%, respectively, compared to 45.0%, 39.4%, and 67.7% in the non-resection group, with no significant differences ( P>0.05). The median postoperative MSTS functional score after PSM was significantly lower in the resection group 23(18, 25) points than in the non-resection group 26.5(24.3, 27.8) points ( U=43.000, P=0.007). Multivariate Cox regression analysis identified grade III histology ( HR=3.794, P=0.002) and tumor involvement angle around the femur greater than 180° ( HR=2.729, P=0.030) as independent risk factors for death. Age over 55 years ( HR=4.185, P=0.015), tumor diameter greater than 8 cm ( HR=4.290, P=0.014), and involvement of the intermuscular compartment ( HR=3.794, P=0.017) were associated with increased risk of local recurrence. Grade III histology ( HR=3.848, P=0.006) and involvement of the intermuscular compartment ( HR=2.500, P=0.045) were associated with distant metastasis. Conclusion:For patients with thigh soft tissue sarcoma involving femoral cortex involvement but no medullary cavity invasion, bone resection did not improve survival, recurrence or metastasis compared with patients in non-resection group. A relatively more conservative surgical approach may be advisable to preserve limb function without compromising oncological prognosis.

Collagen-based materials, renowned for their biocompatibility and minimal immunogenicity, serve as exemplary substrates in a myriad of biomedical applications. Collagen-based micro/nanogels, in particular, are valued for their increased surface area, tunable degradation rates, and ability to facilitate targeted drug delivery, making them instrumental in advanced therapeutics and tissue engineering endeavors. Although extensive reviews on micro/nanogels exist, they tend to cover a wide range of biomaterials and lack a specific focus on collagen-based materials. The current review offers an in-depth look into the manufacturing technologies, drug release mechanisms, and biomedical applications of collagen-based micro/nanogels to address this gap. First, we provide an overview of the synthetic strategies that allow the precise control of the size, shape, and mechanical strength of these collagen-based micro/nanogels by controlling the degree of cross-linking of the materials. These properties are crucial for their performance in biomedical applications. We then highlight the environmental responsiveness of these collagen-based micro/nanogels, particularly their sensitivity to enzymes and pH, which enables controlled drug release under various pathological conditions. The discussion then expands to include their applications in cancer therapy, antimicrobial treatments, bone tissue repair, and imaging diagnosis, emphasizing their versatility and potential in these critical areas. The challenges and future perspectives of collagen-based micro/nanogels in the field are discussed at the end of the review, with an emphasis on the translation to clinical practice. This comprehensive review serves as a valuable resource for researchers, clinicians, and scientists alike, providing insights into the current state and future directions of collagen-based micro/nanogel research and development.

Objective:To explore an initial target rate for resuscitation attempted by bystanders for patients experiencing out-of-hospital cardiac arrest in China.Methods:We searched seven electronic databases, including CNKI, VIP, Wanfang, CBM, PubMed, Cochrane, EMBase, for Utstein-style reports of out-of-hospital cardiac arrest, containing data on bystander resuscitation and survival to discharge or 30 days after arrest. All patients with cardiac arrest diagnosed at prehospital emergency medical services were included. Meta-analysis was performed to pool rate ratios (RR) with 95% confidence intervals (CI) of the rate of survival to discharge or 30 days. The population attributable risk percent (PARP) was calculated with RR, and the growth rate curve of PARP following bystander cardiopulmonary resuscitation rate was plotted. We established a multiple linear regression model to show the change in survival to discharge or 30 days with increasing rates of resuscitation attempted by bystanders.Results:We included 24 cohorts with 279 641 patients experiencing out-of-hospital cardiac arrest. The median rates of bystander cardiopulmonary resuscitation and survival to discharge or 30 days after arrest in seven cohorts from China were 2.8% and 0.47%, respectively, both far below the first tertiles in all cohorts worldwide (10.0% and 2.70%, respectively). The meta-analysis showed that resuscitation attempts by bystanders increased the chance of survival to discharge or 30 days ( RR=5.91, 95% CI 3.28-10.66; I2=0, P=0.990). The growth rate curve on PARP showed a rapid attenuation in the increase of PARP after the bystander resuscitation rate reached 10%. The multiple linear regression showed that resuscitation attempted by bystanders could explain 74.4% of the variation in the rates of survival to discharge or 30 days. By increasing the bystander resuscitation rate to 10%, the rate of survival to discharge or 30 days could increase to 1.40% (95% CI 0.76%-2.05%), and the PARP could increase from 19.7% to 32.9%. Conclusions:Low rate of resuscitation attempted by bystanders is currently the main reason for the poor survival rate of out-of-hospital cardiac arrest in China. It is recommended to increase the rate of resuscitation attempted by bystanders in stages with an initial target rate of 10%.
