This study investigates the expression pattern and functional significance of EF-hand domain-containing protein 2 (EFHD2) in hepatocellular carcinoma (HCC), with particular focus on its regulatory effects on tumor proliferation, migration, and invasion. Cellular experimental study was completed from June 2024 to January 2025 in the Basic Laboratory of the General Hospital of Southern Theater Command. TCGA database to determine EFHD2 expression and its clinicopathological correlations. GSCA database to assess methylation patterns and immune infiltration. Model of transient overexpression and knockdown of EFHD2 was constructed in hepatocellular carcinoma cells Hep3B, then RT-qPCR and Western blot were applied to verify the transfection efficiency. CCK-8 and colony formation assays for proliferation assessment, Transwell chambers for migration/invasion quantification. Protein-protein interaction networks were constructed via STRING, followed by GO/KEGG enrichment analysis. Statistical analysis was performed using the two independent samples t-test. The results showed that EFHD2 demonstrated significant upregulation in HCC tissues versus normal controls ( P<0.05). Elevated EFHD2 expression correlated with advanced clinical stage ( P<0.05) and poor differentiation ( P<0.05). In the CCK-8 assay, the EFHD2 overexpression group demonstrated significantly higher cell viability than the control group, as evidenced by 450 nm relative absorbance values on Day 1 (0.529±0.019 vs. 0.515±0.016, F=0.041, P=0.320), Day 2 (1.356±0.019 vs. 1.094±0.042, F=3.833, P<0.001), Day 3 (2.817±0.049 vs. 2.143±0.124, F=3.833, P<0.001), and Day 4 (3.848±0.015 vs. 3.430±0.021, F=0.469, P<0.001). The EFHD2 knockdown group showed reduced cell viability compared to controls: Day 1 (0.541±0.020 vs. 0.552±0.015, F=0.098, P=0.423), Day 2 (1.154±0.009 vs. 1.326±0.029, F=2.485, P<0.001), Day 3 (2.453±0.041 vs. 2.653±0.031, F=0.479, P<0.001), and Day 4 (3.685±0.038 vs. 3.836±0.021, F=6.804, P<0.001). In colony formation assays, the overexpression group displayed a significant increase in colony numbers (254.667±23.861 vs. 186.000±16.703, F=0.865, P=0.015), whereas the knockdown group exhibited decreased colony formation (229.000±24.637 vs. 306.667±36.501, F=0.988, P=0.038). In Transwell assays, the EFHD2 overexpression group revealed enhanced migratory capacity [ (605.000±72.670) cells vs. (472.667±28.095) cells, F=2.462, P=0.042] and invasive potential [(767.333±21.221) cells vs. (414.333±16.623) cells, F=0.331, P<0.001]. The knockdown group showed attenuated migration [(311.000±71.084) cells vs. (479.667±50.846) cells, F=0.718, P=0.029] and invasion [(247.667±48.263) cells vs. (345.667±32.130) cells, F=0.727, P=0.043] compared to controls. The network of EFHD2-interacting proteins was further constructed by the STRING database, and the GO and KEGG analysis were used to perform bioinformatics analysis reveal that EFHD2 is mainly involved in actin cytoskeleton regulation. In conclusion, EFHD2 is highly expressed in HCC and is involved in the process of proliferation, migration and invasion of HCC.

Changes in hair follicle stem cells (HFSCs) can affect scalp aging and hair growth. With increasing age, HFSCs exhibit a decrease in quiescence maintenance and self-renewal capacity, as well as differentiation potential, leading to shortened hair growth cycles and even hair loss. This review summarizes recent research advances in the multifactorial interactions underlying hair loss, including the regulatory mechanisms of HFSC quiescence, the impact of aging on HFSC function, and aging of the stem cell microenvironment. Additionally, this review discusses the relationship between stem cells and hair shafts, and the mechanisms of action of stem cells in scalp aging, including alterations in signaling pathways, chromatin remodeling, and epigenetic regulation, etc. Furthermore, stem cell-based therapeutic strategies are summarized, such as the use of stem cells or their secreting exosomes, modulation of the stem cell microenvironment, and pharmacological interventions.

Objective To explore the expression level of serum long non-coding RNA(lncRNA)T342620 in patients with hepatocellular carcinoma(HCC)and the clinical value of single or combined detection with al-pha-fetoprotein(AFP)for HCC.Methods Case-control studies were conducted.A total of 69 patients with primary hepatocellular carcinoma(HCC group),32 patients with hepatitis B(hepatitis B group),20 patients with liver cirrhosis(liver cirrhosis group),30 patients after transcatheter hepatic arterial chemoembolization(TACE)for primary hepatocellular carcinoma(HCC postoperative group)and 50 healthy patients(health ex-amination group)treated in the General Hospital of Southern Theatre Command of PLA from April 2021 to May 2023 were selected as the study objects.The serum total RNA was extracted and the relative expression level of lncRNA T342620 in serum was detected by real-time quantitative PCR.Combined with the clinical di-agnosis and treatment data of patients,the correlation between its expression and pathological characteristics and serological indexes was analyzed,and the specificity and sensitivity of lncRNA T342620 alone and in com-bination with AFP in the diagnosis of HCC were analyzed by receiver operating characteristic(ROC)curve.The diagnostic efficacy was judged according to the area under the curve,and its application value in the diag-nosis of HCC was evaluated.The chi-square test was used for comparison between groups,and the Spearman method was used for correlation analysis.Results The serum expression levels of lncRNA T342620 in liver cancer group and postoperative liver cancer group were higher than those in healthy physical examination group,hepatitis B group and liver cirrhosis group,and the differences were statistically significant(P＜0.001).Clinical pathological and serological index analysis revealed that as the tumor size increased,the serum lncRNA-T342620 expression level also increased.In the HCC group,the serum lncRNA T342620 expression level was negatively correlated with albumin(ALB)and the A/G ratio(P＜0.05),while it was positively cor-related with α-L-fucosidase(AFU)and HBV-DNA(P＜0.05).In patients from the HCC postoperative group,the serum lncRNA T342620 expression level was positively correlated with total bile acid(TBA)(P＜0.05).ROC curve analysis demonstrated that when using serum lncRNA T342620 to distinguish,the sensitivi-ty and the specificity were 55.1％and 94.1％,respectively,indicating good diagnostic value.When combined with AFP detection,the sensitivity and the specificity improved to 91.3％and 91.2％,respectively,which were higher than those of individual indicators and had a superior diagnostic efficiency with area under the cuve(AUC)of 0.954 compared to AUC of AFP or lncRNA-T342620 alone(0.906,0.758),and the differ-ences were statistically significant(P＜0.05).Conclusion Serum lncRNA T342620 may be a new serological index for the auxiliary diagnosis of HCC.

Objective To analyse the experience of out-of-hospital self-management in patients with temporary enterostomy after colorectal cancer surgery,aiming to provide a guidance for developing an effectively continuous nursing plan. Methods In this descriptive qualitative study,the purpose sampling method was applied to include 11 patients with temporary enterostomy discharged after colorectal cancer surgery as the study participants between January and October 2023. NVivo12 software and content analysis method were used to analyse the data acquired from interview and to extract the themes. Results Totally,4 themes and 8 sub-themes were extracted,including the lack of stoma management skills and low willingness to learn the skills ( lack of stoma management skills and unwillingness to actively learn skills for stoma management),difficulty in living with stoma (difficulty in living with changes of daily life brought by stoma,and expectations for the life advices of care providers),insufficient psychological and social support (negative emotions towards the life with stoma and lack of psychological support from family,friends and medical staff),and a gap between patients' expectations and actual effects on continuous nursing management (poor effectiveness of continuity of care and the high expectations for continuity of care). Conclusion Further improvement are required for the out-of-hospital self-management skills for the patients with temporary colostomy after colorectal cancer surgery. The skills can be improved by taking multiple measures such as education of nursing skills,advice on daily life,psychological support,and improvement of nursing effectiveness,therefore to enhance the out-of-hospital self-management behaviour of patients with colostomy.
