Objective To investigate the role and regulatory mechanism of LINC00657 in the progression of cervical cancer. Methods Bioinformatics analysis predicted potential binding sites between LINC00657 and miR-30a-5p and between miR-30a-5p and Skp2. These sites were verified by using RNA immunoprecipitation and dual-luciferase reporter experiments. LINC00657, miR-30a-5p, and Skp2 mRNA expression levels in cervical cancer tissues and cell lines were assessed by utilizing RT-qPCR. Western blot analysis was employed to examine the protein levels of Skp2 in cells and subcutaneous xenograft tumor models in nude mice. Immunohistochemistry was applied to analyze Skp2 expression in animal tissues. The cellular processes of cervical cancer cell lines were evaluated through CCK-8, scratch, and Transwell assays. Results LINC00657 and Skp2 presented binding sites for miR-30a-5p. In cervical cancer, LINC00657 and Skp2 showed high expression levels (P<0.05), whereas miR-30a-5p displayed low expression (P<0.05). Functional experiments demonstrated that linc00657 upregulates Skp2 expression, a process that is dependent on its sequestration of miR-30a-5p. Conclusion LINC00657 promoted the malignant progression of cervical cancer by upregulating Skp2 expression through specifically sequestering miR-30a-5p, thereby relieving its inhibitory effect on the target gene Skp2.

Lung cancer is a leading cause of cancer-related morbidity and mortality worldwide. Coupled with the substantial workload, the clinical management of lung cancer is challenged by the critical need to efficiently and accurately process increasingly complex medical information. In recent years, large language models (LLMs) technology has undergone explosive development, demonstrating unique advantages in handling complex medical data by leveraging its powerful natural language processing capabilities, and its application value in the field of lung cancer diagnosis and treatment is continuously increasing. The paper systematically analyzes that the exceptional potential of LLMs in lung cancer auxiliary diagnosis, tumor feature extraction, automatic staging, progression/outcome analysis, treatment recommendations, medical documentation generation, and patient education. However, they face critical technical and ethical challenges including inconsistent performance in complex integrated decision-making (e.g., TNM staging, personalized treatment suggestions) and "black box" opacity issues, along with dilemmas such as training data biases, model hallucinations, data privacy concerns, and cross-lingual adaptation challenges ("data colonization"). Future directions should prioritize constructing high-quality multimodal corpora specific to lung cancer, developing interpretable and compliant specialized models, and achieving seamless integration with existing clinical workflows. Through dual drivers of technological innovation and ethical standardization, LLMs should be prudently advanced for holistic lung cancer management processes, ultimately promoting efficient, standardized, and personalized diagnosis and treatment practices.

Objective:To explore the effectiveness, safety, and cost among urinary follicle-stimulating hormone (u-FSH), recombinant FSH (r-FSH)α, and r-FSHβ in the early follicular phase prolonged protocol for patients under 35 years old with normal ovarian function.Methods:It was a retrospective cohort study. Patients under 35 years old with normal ovarian function who underwent early follicular phase prolonged protocol for ovulation stimulation and using in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) for fertilization in Reproductive Health Hospital of the Third Affiliated Hospital of Zhengzhou University from January 2018 to December 2023 were recruited, including the fresh and frozen-thawed embryo transfer (FET) cycles. Patients were divided into u-FSH group, r-FSHα group, and r-FSHβ group. A total of 1 048 ovarian stimulation cycles were included, with 150 cycles, 490 cycles and 408 cycles in the three groups respectively. A total of 710 FET cycles with fresh cycle cancellation were included, with 95 cycles, 320 cycles and 295 cycles in the three groups respectively. The baseline data, pregnancy outcomes, safety, and cost were compared among the three groups. The main observation indicators were cumulative pregnancy rate and cumulative live birth rate (CLBR). A binary logistic regression model was used to control confounding factors, and to analyze the relationship between three ovulation inducing medicine and CLBR. Results:The difference in the number of oocytes retrieved among the u-FSH group, r-FSHα group, and r-FSHβ group was statistically significant [13.0 (10.0, 16.0), 14.0 (11.0, 18.0), 15.0 (11.0, 19.0), respectively, P=0.012], and the difference in the number of 2PN embryos was statistically significant [9.0 (6.0, 12.0), 10.0 (7.0, 13.0), 10.0 (7.0, 13.0), respectively, P=0.046]. There were no statistically significant differences in the number of available embryos, available embryo rate, the number of high-quality embryos, high-quality embryo rate, available blastocyst formation rate, fresh cycle clinical pregnancy rate, live birth rate in fresh cycle, cumulative pregnancy rate of frozen embryos with fresh cycle cancellation, CLBR of frozen embryos with fresh cycle cancellation, cumulative clinical pregnancy rate, CLBR, moderate to severe ovarian hyperstimulation syndrome incidence, ectopic pregnancy rate, multiple pregnancy rate and neonatal malformation rate among the three groups (all P>0.05). In terms of economy, the u-FSH group had the lowest total gonadotropin cost for each patient, while the r-FSHα group had the highest. The differences among the three groups were statistically significant [u-FSH group 4 429.08 (3 198.78, 5 044.23) yuan, r-FSHα group 6 023.72 (5 433.75, 7 529.65) yuan, r-FSHβ group 5 480.00 (4 550.90, 6 437.86) yuan, P<0.001]. Binary logistic regression analysis was conducted, using u-FSH as a control. The CLBR of the r-FSHα group and r-FSHβ group showed no statistically significant difference compared with the u-FSH group (a OR=0.95, 95% CI: 0.57-1.58, P=0.838; a OR=0.89, 95% CI: 0.54-1.48, P=0.654). Conclusion:For patients under 35 years old with normal ovarian function undergoing long protocol ovarian stimulation, the effectiveness and safety of the three ovarian-stimulating medicine are similar, but u-FSH has economic advantages.

PURPOSE:
The secondary damage of spinal cord injury (SCI) starts from the collapse of the blood spinal cord barrier (BSCB) to chronic and devastating neurological deficits. Thereby, the retention of the integrity and permeability of BSCB is well-recognized as one of the major therapies to promote functional recovery after SCI. Previous studies have demonstrated that activation of hypoxia inducible factor-1α (HIF-1α) provides anti-apoptosis and neuroprotection in SCI. Endogenous HIF-1α, rapidly degraded by prolylhydroxylase, is insufficient for promoting functional recovery. Dimethyloxalylglycine (DMOG), a highly selective inhibitor of prolylhydroxylase, has been reported to have a positive effect on axon regeneration. However, the roles and underlying mechanisms of DMOG in BSCB restoration remain unclear. Herein, we aim to investigate pathological changes of BSCB restoration in rats with SCI treated by DOMG and evaluate the therapeutic effects of DMOG.
METHODS:
The work was performed from 2022 to 2023. In this study, Allen's impact model and human umbilical vein endothelial cells were employed to explore the mechanism of DMOG. In the phenotypic validation experiment, the rats were randomly divided into 3 groups: sham group, SCI group, and SCI + DMOG group (10 rats for each). Histological analysis via Nissl staining, Basso-Beattie-Bresnahan scale, and footprint analysis was used to evaluate the functional recovery after SCI. Western blotting, TUNEL assay, and immunofluorescence staining were employed to exhibit levels of tight junction and adhesion junction of BSCB, HIF-1α, cell apoptosis, and endoplasmic reticulum (ER) stress. The one-way ANOVA test was used for statistical analysis. The difference was considered statistically significant at p < 0.05.
RESULTS:
In this study, we observed the expression of HIF-1α reduced in the SCI model. DMOG treatment remarkably augmented HIF-1α level, alleviated endothelial cells apoptosis and disruption of BSCB, and enhanced functional recovery post-SCI. Besides, the administration of DMOG offset the activation of ER stress induced by SCI, but this phenomenon was blocked by tunicamycin (an ER stress activator). Finally, we disclosed that DMOG maintained the integrity and permeability of BSCB by inhibiting ER stress, and inhibition of HIF-1α erased the protection from DMOG.
CONCLUSIONS
Our findings illustrate that the administration of DMOG alleviates the devastation of BSCB and HIF-1α-induced inhibition of ER stress.
