Review
Radiofrequency ablation (RFA) offers a minimally invasive solution for benign, autonomously functioning (AFTN), and malignant thyroid nodules. The technique utilizes high-frequency alternating current to induce coagulative necrosis, effectively destroying target tissue. RFA is performed in the outpatient setting with local anesthesia and sonographic guidance. RFA is effective in producing substantial volume reduction rates in benign nodules and is emerging as a favorable option in AFTN and papillary thyroid microcarcinoma. RFA's advantages include lower complication rates, minimal scarring, and improved quality-of-life outcomes compared to surgery. However, its efficacy in larger and recurrent malignancies requires further investigation.

Review
Thyroid carcinoma of follicular cell origin exists on a histopathologic and clinical spectrum. The authors focus on the category of tumors that fall between the very favorable well-differentiated thyroid carcinomas and the very unfavorable anaplastic thyroid carcinomas. These intermediately aggressive tumors include poorly differentiated thyroid carcinoma and the newly defined differentiated high-grade thyroid carcinoma. Both diagnoses require certain histopathologic requirements be met in order to accurately identify these tumors post-operatively. Management remains primarily surgical though adjunctive treatments such as molecular targeted therapies (eg, tyrosine kinase inhibitors) and differentiation therapy (to restore tumor response to radioactive iodine) are also becoming available.

Review
Molecular testing for cytologically indeterminate thyroid nodules has demonstrated benefit by reducing the need for diagnostic thyroidectomies and reducing costs. Its use is currently recommended in practice guidelines from the American Thyroid Association and the American Association of Endocrine Surgeons when clinically appropriate. Moreover, there is growing evidence that molecular testing may provide prognostic information and can detect targetable genetic alterations which may expand treatment options for refractory advanced thyroid cancers.

Breast cancer (BC) remains the most prevalent cancer among women worldwide, despite significant advancements in its prevention and treatment. The escalating incidence of BC globally necessitates continued research into novel diagnostic and therapeutic strategies. Metabolomics, a burgeoning field, offers a comprehensive analysis of all metabolites within a cell, tissue, system, or organism, providing crucial insights into the dynamic changes occurring during cancer development and progression. This review focuses on the metabolic alterations associated with BC, highlighting the potential of metabolomics in identifying biomarkers for early detection, diagnosis, treatment and prognosis. Metabolomics studies have revealed distinct metabolic signatures in BC, including alterations in lipid metabolism, amino acid metabolism, and energy metabolism. These metabolic changes not only support the rapid proliferation of cancer cells but also influence the tumour microenvironment and therapeutic response. Furthermore, metabolomics holds great promise in personalized medicine, facilitating the development of tailored treatment strategies based on an individual's metabolic profile. By providing a holistic view of the metabolic changes in BC, metabolomics has the potential to revolutionize our understanding of the disease and improve patient outcomes.

BACKGROUND
The lack of specific molecular targets and the rapid spread lead to a worse prognosis of triple-negative breast cancer (TNBC). Therefore, identifying new therapeutic and prognostic biomarkers helps to develop effective treatment strategies for TNBC.
METHODS
Through preliminary bioinformatics analysis, FOXCUT was found to be significantly overexpressed in breast cancer, especially in TNBC. Tissue samples were collected from 15 TNBC patients, and qRT-PCR was employed to validate the expression of FOXCUT in both TNBC patient tissues and TNBC cell lines. We also carried out the GSEA analysis and KEGG enrichment analysis of FOXCUT. Additionally, the effects of FOXCUT knockdown on TNBC cell malignant behaviors, and aerobic glycolysis were assessed by methods including CCK-8, Transwell, western blot, and Seahorse XF 96 analyses. Moreover, utilizing databases predicting interactions between ceRNAs, corresponding lncRNA-miRNA binding relationships, and miRNA-mRNA interactions were predicted. These predictions were subsequently validated through RNA immunoprecipitation and dual-luciferase reporter assays.
RESULTS
FOXCUT exhibited high expression in both TNBC tissues and cell lines, fostering cell malignant behaviors and glycolysis. FOXCUT was found to sponge miR-337-3p, while miR-337-3p negatively regulated the expression of ANP32E. Consequently, FOXCUT ultimately facilitated the malignant phenotype of TNBC by upregulating ANP32E expression.
CONCLUSION
This study elucidated the role of FOXCUT in elevating aerobic glycolysis levels in TNBC and driving malignant cancer cell development via the miR-337-3p/ANP32E regulatory axis.

Review
Biological sex disparities manifest at various stages of drug addiction, including craving, substance abuse, abstinence, and relapse. These discrepancies are underpinned by notable distinctions in neurobiological substrates, encompassing brain structures, functions, and neurotransmitter systems implicated in drug addiction. Neuronal biomarkers, such as neurotransmitters, signaling proteins, and genes may be associated with the diagnosis, prognosis, and treatment outcomes in both biological sexes afflicted by drug abuse. Sex differences in the neural reward system, mainly through dopaminergic transmission during drug abuse, can be attributed to modifications in neurotransmitter systems and signaling pathways. This results in distinct patterns of neural activation and responsiveness to addictive substances in males and females. Sex hormones, the estrus/menstrual cycle, and cerebral neurochemistry contribute to the progression of psychological and physiological dependence in both male and female individuals grappling with addiction. Moreover, the alteration of sex hormone balance and neurotransmitter release plays a pivotal role in substance use disorders, subsequently modulating cognitive functions pertinent to reward, including memory formation, decision-making, and locomotor activity. Comparative investigations reveal distinctions in brain region volume, gene expression, neuronal firing, and circuitry in substance use disorders affecting individuals of both biological sexes. This review examines prevalent substance use disorders to elucidate the impact of sex hormones as therapeutic biomarkers on the mesocorticolimbic neurotransmitter systems via diverse mechanisms within the addicted brain. We underscore the imperative necessity of considering these variations to gain a deeper comprehension of addiction mechanisms and potentially discern sex-specific neuronal biomarkers for tailored therapeutic interventions.

OBJECTIVE
This study aimed to compare the difference in perioperative outcomes and prognosis between neoadjuvant immunochemotherapy (nICT) and neoadjuvant chemoradiotherapy (nCRT) for locally advanced esophageal squamous cell carcinoma (LA-ESCC).
METHODS
The LA-ESCC patients receiving nICT or nCRT were identified from a prospectively maintained database at Zhongshan Hospital of Fudan University between Jan 2018 and March 2022. Propensity score matching (PSM) was performed to balance the two groups.
RESULTS
A total of 124 patient pairs were enrolled in the final analysis. The complete pathological response rate (20.2% vs. 29.0%, p=0.140) was similar in the two groups while the lower major pathological response rate (44.4% vs. 61.3%, p=0.011) was observed in the nICT group. nICT was associated with a lower rate of adverse events (42.7% vs. 55.6%, p=0.047) without additional postoperative complications (38.7% vs. 35.5%, p=0.693). The nICT group had lower distant metastasis (6.5% vs. 16.1%, p=0.027) and overall recurrence (11.3% vs. 23.4%, p=0.019) in the postoperative 1 year. Also, nICT was associated with better progression-free survival (HR=0.50; 95% CI: 0.32-0.77; p=0.002). Cox proportional hazard analysis showed that nICT (univariable: HR=0.55; 95% CI: 0.37-0.82; p=0.003; multivariable: HR=0.44; 95% CI: 0.29-0.65; p<0.001) was one of the independent prognostic factors for progression-free survival. The two groups had similar overall survival (HR=0.62; 95%CI: 0.36-1.09; p=0.094) at the latest follow-up.
CONCLUSION
This retrospective study showed that nICT was safe and effective for LA-ESCC patients. Further verification is needed in the randomized controlled trials.

The 26S proteasome non-ATPase regulatory subunit 11 is a multiprotein complex involved in the ATP-dependent degradation of ubiquitinated proteins, and PSMD11 plays a key role in the regulation of embryonic stem cell proteasome activity. However, the role of PSMD11 in hepatocellular carcinoma has not been studied. In this study, it was found that the expression of PSMD11 in HCC tissues was significantly higher than that in para-cancerous tissues, and was associated with poor prognosis. The results of in vitro experiments showed that PSMD11 knockdown could effectively inhibit the proliferation and apoptosis of hepatoma cell lines, and flow cytometry showed that the G0/G1 phase was significantly prolonged. Through protein spectrometry, immunoprecipitation and in vitro experiments, it was found that PSMD11 can promote the proliferation of hepatocellular carcinoma through regulating the ubiquitination of CDK4 and enhancing its protein stability. This study explores the mechanism of action of PSMD11 in hepatocellular carcinoma and provides new insights for the treatment of hepatocellular carcinoma.

Review
Cognitive challenges and brain structure variations are common in autism spectrum disorder (ASD) but are rarely explored in middle-to-old aged autistic adults. Cognitive deficits that overlap between young autistic individuals and elderlies with dementia raise an important question: does compromised cognitive ability and brain structure during early development drive autistic adults to be more vulnerable to pathological aging conditions, or does it protect them from further decline? To answer this question, we have synthesized current theoretical models of aging in ASD and conducted a systematic literature review (Jan 1, 1980 - Feb 29, 2024) and meta-analysis to summarize empirical studies on cognitive and brain deviations in middle-to-old aged autistic adults. We explored findings that support different aging theories in ASD and addressed study limitations and future directions. This review sheds light on the poorly understood consequences of aging question raised by the autism community to pave the way for future studies to identify sensitive and reliable measures that best predict the onset, progression, and prognosis of pathological aging in ASD.

Malignant renal rhabdoid tumor (MRTK) is an aggressive and rare malignancy primarily affecting infants and young children. The intricate interactions within the Tumor Microenvironment (TME) are crucial in shaping MRTK's progression. This study elucidates the significance of tumor-associated macrophages(TAMs) within this milieu and their interplay with eukaryotic translation initiation factor 4E-binding protein 1 (EIF4EBP1) in tumor cells, collectively contributing to MRTK's malignant advancement. Through comprehensive analysis of clinical samples and the TARGET database, EIF4EBP1 emerges as a central macrophage-associated gene with robust prognostic implications. Elevated EIF4EBP1 expression correlates with poor prognosis and heightened infiltration of TAMs. Functional validation demonstrates that EIF4EBP1 knockdown in G401 cells significantly attenuates self-proliferation, migration, and invasion. Moreover, EIF4EBP1 regulates macrophage recruitment and M2 polarization through the ERK/P38 MAPK-MIF axis. Notably, M2 macrophages reciprocally foster the malignant behavior of MRTK tumor cells. This study unveils the pivotal role of EIF4EBP1 in propelling MRTK's malignant progression, unraveling a complex regulatory network involving EIF4EBP1 and TAMs. These findings underscore EIF4EBP1 as a promising biomarker and highlight its therapeutic potential in MRTK management.
