The growing microbial resistance to traditional medicines necessitates in-depth analysis of medicine-microbe interactions (MMIs) to develop new therapeutic strategies. Widely used artificial intelligence models are limited by sparse observational data and prevalent noise, leading to over-reliance on specific data for feature extraction and reduced generalization ability. To address these limitations, we integrate Kolmogorov-Arnold Networks (KANs), independent subspaces, and collaborative decoding techniques into the masked graph autoencoder (Mask GAE) framework, creating an innovative MMI prediction model with enhanced accuracy, generalization, and interpretability.

Cancer Biol Ther

December 2024

Department of Anorectal Surgery, The Quzhou Affiliated Hospital of Wenzhou Medical University, Quzhou People's Hospital, Quzhou, Zhejiang, PR China.

Article Synopsis
  • Papillary thyroid cancer (PTC) is increasing in incidence, and this study investigates the role of TM4SF4 in its progression, finding it significantly upregulated in PTC cases.
  • TM4SF4 is identified as a potential diagnostic marker for PTC, with analyses indicating its involvement in cell junctions and immune activation related to the disease.
  • Experimental results show that reducing TM4SF4 levels decreases cell growth and spread of PTC, while reactivating the AKT pathway can reverse these effects, underscoring TM4SF4's role in promoting PTC progression.

November 2024

Zhejiang Provincial Clinical Research Center for Obstetrics and Gynecology, Department of Obstetrics and Gynecology, The Second Affiliated Hospital of Wenzhou Medical University, No. 109 Xueyuan Xi Road, Wenzhou, Zhejiang, 325027, China.

Article Synopsis
  • Cisplatin (DDP) is a common chemotherapy drug used for treating cervical cancer, particularly in advanced cases or for patients wishing to preserve fertility; TRAIL is a protein that can selectively induce death in cancer cells.
  • Human chorion-derived mesenchymal stem cells (hCD-MSCs) were modified to enhance TRAIL production and their exosomes (hCD-MSCs-Exo) were developed as delivery vehicles for DDP via a method called electroporation.
  • The combination of DDP and hCD-MSCs-Exo demonstrated improved effectiveness in reducing cancer cell proliferation and promoting apoptosis in vitro and in vivo, with minimal toxicity, indicating a promising therapeutic approach for cervical cancer treatment.

Int J Nanomedicine

November 2024

Department of Obstetrics, The Quzhou Affiliated Hospital of Wenzhou Medical University, Quzhou People's Hospital, Quzhou, 324000, People's Republic of China.

Background: Diabetes Mellitus (DM) is a substantial health concern worldwide, and its incidence is progressively escalating. Conventional pharmacological interventions frequently entail undesirable side effects, and while probiotics offer benefits, they are hindered by constraints such as diminished stability and effectiveness within the gastrointestinal milieu. Given these complications, the advent of bioengineered probiotics is a promising alternative for DM management.

Current views on mechanisms of the FLASH effect in cancer radiotherapy.

Natl Sci Rev

October 2024

State Key Laboratory of Nuclear Physics and Technology, School of Physics, Peking University, Beijing 100871, China.

FLASH radiotherapy (FLASH-RT) is a new modality of radiotherapy that delivers doses with ultra-high dose rates. The FLASH effect was defined as the ability of FLASH-RT to suppress tumor growth while sparing normal tissues. Although the FLASH effect has been proven to be valid in various models by different modalities of irradiation and clinical trials of FLASH-RT have achieved promising initial success, the exact underlying mechanism is still unclear.

Article Synopsis
  • A study investigated the relationship between chronic lymphocytic thyroiditis (CLT) and lymph node (LN) metastases in papillary thyroid carcinoma (PTC), as previous research showed conflicting results on this connection.
  • Clinical data from 773 PTC patients were analyzed, revealing that those with CLT had a significantly lower incidence of LN metastasis and a higher number of LNs dissected compared to those without CLT, both before and after using propensity score matching (PSM).
  • The findings suggest that CLT may play a protective role against LN metastases in PTC patients, demonstrated by lower odds of metastasis in both matched and unmatched groups.

Study Question: What is the significance of visceral adipose tissue (VAT) in the pathogenesis of polycystic ovary syndrome (PCOS) and its impact on the regulation of metabolic disorders in women with PCOS?

Summary Answer: We revealed a potentially causal relationship between increased genetically predicted VAT and PCOS-related traits, and found that VAT exhibited impaired glucose metabolism and mitochondrial oxidative phosphorylation (OXPHOS) in women with PCOS.

What Is Known Already: PCOS is a common reproductive endocrine disorder accompanied by many metabolic abnormalities. Adipose tissue is a metabolically active endocrine organ that regulates multiple physiological processes, and VAT has a much stronger association with metabolism than subcutaneous adipose tissue does.

Background: Low peak expiratory flow (PEF) rate is common in patients with stroke. Studies on changes in PEF rates in patients with stroke often have small sample sizes, limiting the generalizability of their findings.

Aim: This study aimed to compare the PEF rates between patients who were post-stroke with or without pneumonia and age- and sex-matched healthy controls and explore the PEF-pneumonia association among stroke survivors.

To analyze the clinical efficacy and its influencing factors of vedolizumab (VDZ) in the treatment of ulcerative colitis (UC). The patients with moderately-to-severely active UC, who underwent VDZ treatment at the Second Affiliated Hospital of Wenzhou Medical University from November 2020 to November 2023 were retrospectively included. Based on whether 5-aminosalicylic acid (5-ASA) was used in combination with VDZ treatment, the patients were divided into combination group (received combination therapy of VDZ and 5-ASA) and monotherapy group (received monotherapy of VDZ).

  • Hemorrhage after tonsil surgery in children poses serious risks, leading to a study aimed at creating a risk warning model for predicting bleeding post-surgery.
  • The study analyzed data from 8,854 children who underwent tonsillectomy, ultimately focusing on 2,724 cases, to distinguish between those who experienced bleeding and those who did not.
  • Using a random forest algorithm, the model achieved a high prediction accuracy of 98.72% for postoperative bleeding, demonstrating potential for improving clinical decision-making despite needing to enhance the recall rate.

Article Synopsis
  • The study investigates the relationship between sedentary behavior, physical activity, and chronic back pain, aiming to understand how these factors might predict chronic pain and brain changes.
  • Over an 8-year follow-up, the research found that individuals sitting for more than 6 hours a day had a 33% increased risk of chronic back pain compared to those sitting 2 hours or less, alongside effects on grey matter volume in various brain regions.
  • Engaging in moderate physical activity and reducing sedentary time were linked to lower back pain risk and improved brain health, indicating that replacing sedentary behavior with physical activity can be beneficial.

Article Synopsis
  • Researchers studied the toxicity of 6PPD-Q, an antioxidant used in rubber production, on zebrafish larvae at varying concentrations, finding that while hatchability remained normal, there were significant reductions in body length and swimming distance.
  • At the highest tested concentration, 6PPD-Q negatively affected the development of dopaminergic neurons and altered neurotransmitter levels, highlighting potential impacts on neurological function.
  • The study also indicated that ghrelin's upregulation could mitigate some of the behavioral deficits caused by 6PPD-Q, suggesting a possible therapeutic pathway to address its toxic effects.

Article Synopsis
  • Albumin-bound paclitaxel (PTX@Alb) struggles to effectively accumulate in tumors due to dense collagen and acquired immune resistance linked to increased PD-L1 expression post-treatment.
  • Researchers discovered that tamoxifen (TAM), a breast cancer treatment, can act as a dual inhibitor of PD-L1 and TGF- while promoting a beneficial protein phosphorylation effect.
  • By creating TPP-TAM@Alb nanoparticles, which combine tamoxifen with mitochondria-targeting and albumin, they successfully reduced collagen expression, improved PTX@Alb accumulation in tumors, and enhanced immune response for better cancer treatment outcomes.
