Objective To explore the research hotspots and development trends in the field of cancer treatment in the past decade. Methods The CNKI and Web of Science Core Collection databases were searched for Chinese and English articles related to cancer treatment published over the last 10 years. Bibliometric research methods were employed, including keyword cluster analysis of published literature. Results A total of 45 455 Chinese articles and 866 958 English articles were retrieved. Combining the visualization analysis results and the current research dilemma of tumor treatment revealed that the current research hotspots of tumor treatment domestically and internationally can primarily focus on four key areas. In the realm of targeted therapy, efforts are directed towards the discovery of new drug targets, overcoming resistance to targeted therapy, and the development of monoclonal antibodies and antibody–drug conjugates. In the field of immunotherapy, the emphasis lies in enhancing the response rate to immune checkpoint inhibitors, determining the mechanisms behind resistance to immunotherapy, and improving the safety of treatment. The research in traditional Chinese medicine (TCM) covers evidence-based evaluation studies on TCM treatment, the identification of populations that can gain the most benefit from TCM, and strategies for improving the quality of life. In the area of novel drug development, cutting-edge technologies, such as organoid-based screening for anticancer drugs, synthetic biology, and artificial intelligence, are under investigation. Conclusion New targeted drugs, immune efficacy improvement, multidisciplinary integration, nano-delivery, and TCM innovation are the key research directions in the field of tumor therapy in the future.

Objective:To explore the effects of anshen jieyu decoction on hippocampal morphology and regulation of PI3K/AKT signalling pathway with hypothalamic-pituitary-adrenal axis expression in CUMS depressed rats.Methods:Rats were divided into a control group(Control),CUMS model group(CUMS),and ASJYD treatment group(CUMS+ASJYD).Rats in the CUMS and CUMS+ASJYD groups were exposed to 10 different chronic stressors to induce depressive-like behaviors.After modeling,the CUMS+ASJYD group received ASJYD via gavage.Depressive-like behaviors were assessed using the sucrose preference test and open field test.Serum levels of adrenocorticotropic hor-mone(ACTH)and corticosterone(CORT)were measured by ELISA.Hippocampal neuronal morphological changes were observed via Nissl staining,mitochondrial ultrastructure was examined using transmission electron microscopy,and hippocampal PI3K and AKT protein phosphorylation levels were detected by Western blot.Results:Compared with the Control group,the CUMS group showed significantly reduced sucrose consumption,preference rate,total travel distance in the open field,and central zone activity time(P＜0.01).Serum ACTH and CORT levels were elevated(P＜0.01),with disorganized hippocampal cell arrangement,reduced cell count,mitochondrial swelling,cristae blurring/rupture observed under electron microscopy,and decreased phosphorylation levels of PI3 K and AKT proteins(P＜0.01).After ASJYD treatment,the CUMS+ASJYD group exhibited significant improvements in sucrose consumption,preference rate,locomotor activity,and central zone exploration(P＜0.01),accompanied by reduced ACTH/CORT expression,alleviated hippocampal pathology,restored mitochondrial integrity with clear cristae,and increased PI3K/AKT phosphorylation(P＜0.01).Conclusion:Anshen Jieyu decoction significantly improved the depression-like be-haviour of CUMS rats,which may be achieved by down-regulating the hyperactive hypothalamic-pituitary-adrenal axis,regulating the expression of PI3K/AKT signaling pathway,and ameliorating the damage to hippocampal neurons and mi-tochondria.

Paraplegia caused by spinal cord injury is a serious neurological complication, for which surgery is currently the main treatment method. Due to different surgical approaches, patients are usually expected to maintain a passive prone position for a long time or switch between the supine and prone positions. Affected by multiple factors such as neurogenic sensory disorders, pathological changes in muscle tone and operative duration, the risk of intraoperative acquired pressure injury (IAPI) is significantly increased. Current clinical prevention strategies for IAPI in these patients predominantly focus on localized pressure relief during positioning, lacking systematic, standardized comprehensive prevention protocols or evidence-based guidelines. To address it, Department of Nursing, Orthopedics Branch, China International Exchange and Promotive Association for Medical and Health Care, Spinal Trauma Professional Committee, Orthopedics Branch, Chinese Medical Doctor Association, Nursing Group of Spine and Spinal Cord Professional Committee of Chinese Association of Rehabilitation Medicine organized experts in relevant fields to formulate Guideline for the prevention of intraoperative acquired pressure injury in paraplegic patients with spinal cord injury ( version 2025), based on evidence-based medical evidence and latest research results and clinical practice at home and abroad. Eleven recommendations were put forward from the aspects of preoperative risk assessment, intraoperative prevention strategies, postoperative handover and monitoring, and supportive mechanisms for IAPI prevention, aiming to standardize the prevention measures and management strategies of IAPI in paraplegic patients with spinal cord injury and accelerate the recovery of patients and improve the therapeutic effect.

Objective:To explore the value of fetal heart quantification technology in assessing the morphology and function of the fetal heart during normal pregnancy.Methods:This prospective cohort study selected normal fetuses from healthy pregnant women who underwent prenatal ultrasound examinations at Hunan Provincial People's Hospital from January 2023 to October 2024. Using the GE Voluson E10 color Doppler diasonography, routine obstetric ultrasound and fetal echocardiography were performed to assess fetal growth and development and to exclude intracardiac and extracardiac malformations. Clear four-chamber view (4CV) dynamic images of the heart showing the endocardium (duration ≥3 s) were collected. Speckle-tracking analysis was performed using fetal heart quantification software. The measured indicators included the global spherical index (GSI), end-diastolic length of the heart (L-ED), end-diastolic width of the heart (W-ED), and the global longitudinal strain (GLS), fractional area change (FAC), and 24-segment spherical index (SI) of the left ventricle (LV) and right ventricle (RV). The cases were divided into five groups based on gestational age at the time of prenatal ultrasound: 20 +0 to 23 +6, 24 +0 to 27 +6, 28 +0 to 31 +6, 32 +0 to 35 +6, and 36 +0 to 40 +6 weeks. One-way analysis of variance, two independent samples t-test, univariate linear regression analysis, and Pearson correlation analysis were used to explore the differences in the above indicators among different gestational age groups and their correlation with gestational age. Results:A total of 200 pregnant women were included in the cohort, four cases were excluded due to poor image quality that prevented accurate tracking and measurement of relevant indicators. Ultimately, 196 cases (20 +0 to 23 +6 weeks 40 cases, 24 +0 to 27 +6 weeks 34 cases, 28 +0 to 31 +6 weeks 41 cases, 32 +0 to 35 +6 weeks 48 cases, and 36 +0 to 40 +6 weeks 33 cases) were included in the study, with a successful image analysis rate of 98.0%. (1) There were statistically significant differences in 4CV L-ED, 4CV W-ED, LV-FAC, and RV-FAC among the groups at 20 +0 to 23 +6, 24 +0 to 27 +6, 28 +0 to 31 +6, 32 +0 to 35 +6, and 36 +0 to 40 +6 weeks [4CV L-ED: 28.0±3.0, 32.6±4.3, 40.9±4.3, 46.7±4.8, 53.1±5.8, F=3.72; 4CV W-ED: 21.9±1.8, 25.1±4.2, 31.7±3.0, 37.4±4.0, 42.0±4.9, F=2.61; LV-FAC: (51.4±8.0)%, (49.0±10.4)%, (47.3±7.3)%, (43.1±7.5)%, (40.7±8.2)%, F=2.94; RV-FAC: (49.9±10.8)%, (46.2±12.0)%, (46.3±8.3)%, (43.2±8.0)%, (41.9±5.6)%, F=3.09; all P<0.05].(2) The size of the normal fetal heart gradually increased with gestational age, while the heart morphology remained relatively stable (4CV L-ED and 4CV W-ED were positively correlated with gestational age, with regression coefficients of 1.313 and 1.325, respectively, both P<0.001;LV-FAC and RV-FAC were negatively correlated with gestational age with regression coefficients of -0.783 and -0.552, respectively, both P<0.001; GSI, LV-GLS and RV-GLS had no correlations with gestational age, all P>0.05). (3) The SI of LV segments 1 to 17 were higher than the SI of the corresponding RV segments, and the SI of RV segments 20-24 were higher than that of the corresponding LV segments (all P<0.001). Conclusion:Fetal heart quantification technology has a certain value in the assessment of fetal cardiac morphology and function.

Trihelix transcription factors play important roles in plant light responses, growth and development, and stress responses. However, Trihelix has not yet been reported in Eucommia ulmoides. In this study, bioinformatics methods were used to comprehensively identify and analyze the expression patterns of the Trihelix gene family in E. ulmoides, aiming to provide a basis for further functional studies of EuGTs genes. A total of 9 Trihelix gene family members were identified in E. ulmoides, encoding proteins with 339 to 883 amino acids, with isoelectric points ranging from 5.13 to 9.39 and relative molecular weights between 36 992.06 and 97 871.61. Subcellular localization results showed that only EuGT-2 was localized in chloroplasts, while the others were located in the nucleus. The Trihelix gene family was categorized into six subfamilies: GT-1, GT-2, SH4, SIP1, GTγ, and GTδ. EuGTs were distributed among three subfamilies: SH4, GT-1, and GT-2, containing 1, 6, and 2 Trihelix proteins, respectively, with 2 to 17 exons. The promoters of EuGTs contained various cis-acting elements related to hormones, stress, photoperiod, and growth and development. Collinearity analysis revealed 5 collinear gene pairs between E. ulmoides and Arabidopsis thaliana, and 14 collinear gene pairs between E. ulmoides and Populus. Expression pattern analysis showed that EuGTs exhibited tissue-specific expression: EuGT-1, EuGT-2 had the highest expression levels in leaves, EuGT-4, EuGT-6, EuGT-9 had the highest transcriptional levels in marginal peel, and EuGT-5、EuGT-8 were predominantly expressed in the xylem. As leaves developed, EuGTs showed a trend of asynchronous changes. No significant differences in EuGTs expression were observed between male and female flowers, with high expression levels mainly during the induction stage of flowering. The qRT-PCR analysis indicated that most EuGTs genes were most highly expressed in the leaves of E. ulmoides, while EuGT-5 was highly expressed in the stems. Under 200 mmol·L~(-1) NaCl treatment, most EuGTs genes exhibited an initial increase followed by a decrease in expression, significantly responding to salt stress. This study provides important genetic resources for further exploration of EuGTs gene functions and germplasm innovation in E. ulmoides.

OBJECTIVE: Despite the combination of Scutellaria barbata D. Don and Scleromitrion diffusum (Willd.) R.J. Wang (SB-SD) being a recognized Chinese medicinal herbal pair that is commonly used in the treatment of ovarian cancer, there is a poor understanding of their pharmacological mechanisms. This study examines the antitumor properties and potential mechanisms of SB-SD on human ovarian cancer A2780 cells through a multi-omics approach, establishing a pharmacological basis for clinical utilization. METHODS: A range of mass ratios and reagents were used in the hot reflux extraction of SB-SD. The inhibitory effect of the SB-SD extracts on A2780 cell proliferation was assessed using the cell-counting kit 8 assay. A zebrafish tumor implantation model was used to evaluate the effects of SB-SD extracts on tumor growth and metastasis in vivo. Transcriptomics and proteomics were used to investigate alterations in biological pathways in A2780 cells after treatment with different concentrations of SB-SD extract. Cell cycle, cell apoptosis, intracellular free iron concentration, intracellular reactive oxygen species (ROS) concentration, malondialdehyde (MDA), and mitochondrial membrane potential were measured. Real-time quantitative reverse transcription polymerase chain reaction and Western blotting were utilized to investigate the effects of heme catabolism and ferritinophagy on ferroptosis induced by SB-SD extract in A2780 cells. RESULTS: The 70% ethanol extract of SB-SD (a mass ratio of 4:1) inhibited A2780 cell proliferation significantly with a half maximal inhibitory concentration of 660 μg/mL in a concentration- and time-dependent manner. Moreover, it effectively suppressed tumor growth and metastasis in a zebrafish tumor implantation model. SB-SD extract induced the accumulation of free iron, ROS, MDA, and mitochondrial damage in A2780 cells. The mechanisms might involve the upregulated expression of ferritinophagy-related genes microtubule-associated protein 1 light chain 3, autophagy-related gene 5, and nuclear receptor coactivator 4. CONCLUSION SB-SD extract effectively inhibited the development of ovarian cancer both in vitro and in vivo. Its mechanism of action involved inducing ferroptosis by facilitating heme catabolism and ferritinophagy. This herbal pair holds promise as a potential therapeutic option for ovarian cancer treatment and may be utilized in combination with routine treatment to improve the treatment outcomes of ovarian cancer patients.
