Application of Large Language Models in Medical Training Evaluation-Using ChatGPT as a Standardized Patient: Multimetric Assessment.

Background: With the increasing interest in the application of large language models (LLMs) in the medical field, the feasibility of its potential use as a standardized patient in medical assessment is rarely evaluated. Specifically, we delved into the potential of using ChatGPT, a representative LLM, in transforming medical education by serving as a cost-effective alternative to standardized patients, specifically for history-taking tasks.

Objective: The study aims to explore ChatGPT's viability and performance as a standardized patient, using prompt engineering to refine its accuracy and use in medical assessments.

Persist or resist: Immune checkpoint inhibitors in EGFR-mutated NSCLC.

Although epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs), especially third-generation TKIs, have significantly improved the progression-free survival and overall survival of non-small cell lung cancer (NSCLC) patients with EGFR mutation, TKI resistance is inevitable for most patients. Over the past few years, immune checkpoint inhibitors (ICIs) have significantly improved the survival for EGFR-wild type NSCLC patients. However, no significantly improved benefits were observed with ICI monotherapy in EGFR-mutated patients.

CircINADL promotes nasopharyngeal carcinoma metastasis by inhibiting HuR ubiquitin degradation and disrupting the hippo signaling pathway.

Distant metastasis is a primary factor contributing to the low survival rate of patients with nasopharyngeal carcinoma (NPC). Circular RNAs (circRNAs) are increasingly recognized for their roles in cancer initiation and progression. However, the mechanisms underlying the abnormal expression and biological function of circRNA in NPC remain unclear.

Balloon guide catheters for endovascular thrombectomy in patients with acute ischaemic stroke due to large-vessel occlusion in China (PROTECT-MT): a multicentre, open-label, blinded-endpoint, randomised controlled trial.

Background: The effectiveness of using a balloon guide catheter during endovascular thrombectomy in patients with acute ischaemic stroke due to large vessel occlusion of the anterior circulation remains uncertain. We aimed to assess the effectiveness and safety of using a balloon guide catheter during endovascular thrombectomy, compared with using a conventional guide catheter, in this patient population.

Methods: We conducted a multicentre, open-label, blinded-endpoint, randomised controlled trial at 28 hospitals in China.

Hollow Bismuth Nanoparticle-Loaded Gelatin Hydrogel Regulates M2 Polarization of Macrophages to Promote Infected Wound Healing.

Open wounds face severe bacterial infection, which affects the quality of healing. Photothermal antimicrobial therapy has received increasing attention as a broad-spectrum antimicrobial treatment that can avoid drug resistance. A variety of metallic materials have been used in the development of photothermal agents.

Skin Microbiota, Immune Cell, and Skin Fibrosis: A Comprehensive Mendelian Randomization Study.

Background: Microbiota dysbiosis has been reported to lead to leaky epithelia and trigger numerous dermatological conditions. However, potential causal associations between skin microbiota and skin fibrosis and whether immune cells act as mediators remain unclear.

Methods: Summary statistics of skin microbiota, immune cells, and skin fibrosis were identified from large-scale genome-wide association studies summary data.

A splicing isoform of PD-1 promotes tumor progression as a potential immune checkpoint.

The immune checkpoint receptor, programmed cell death 1 (PD-1, encoded by PDCD1), mediates the immune escape of cancer, but whether PD-1 splicing isoforms contribute to this process is still unclear. Here, we identify an alternative splicing isoform of human PD-1, which carries a 28-base pairs extension retained from 5' region of intron 2 (PD-1^28), is expressed in peripheral T cells and tumor infiltrating lymphocytes. PD-1^28 expression is induced on T cells upon activation and is regulated by an RNA binding protein, TAF15.

A versatile natural gelatin-based hydrogel for emergency wound treatment through hemostasis, antibacterial, and anti-inflammation.

Emergency wounds are often accompanied by bacterial infection, oxidative stress, and excessive inflammation due to the inability to quickly close and stop bleeding, resulting in chronic wounds that are difficult to heal. Clinically, surgical suturing is the fastest method for wound closure, but it is only suitable for wounds with small bleeding volumes and causes unsightly scar formation. Consequently, there is a critical need for hemostatic dressings versatile enough to address a spectrum of diverse and intricate wounds, especially in emergency scenarios.

Epigenetic modifications in hematopoietic ecosystem: a key tuner from homeostasis to acute myeloid leukemia.

Hematopoietic stem cells (HSCs) maintain homeostasis in the hematopoietic ecosystem, which is tightly regulated at multiple layers. Acute myeloid leukemia (AML) is a severe hematologic malignancy driven by genetic and epigenetic changes that lead to the transformation of leukemia stem cells (LSCs). Since somatic mutations in DNA methylation-related genes frequently occur in AML, DNA methylation is widely altered and functions as a starting engine for initiating AML.

Successful carinal reconstruction with right main bronchial flap rotational embedded augmentation: a case report.

Background: Tracheo-carinal resection and reconstruction in cases of extensive malignant tumors present a significant surgical challenge, often complicated by high anastomotic tension and potential for incomplete anastomosis.

Case Description: We report on a 45-year-old male with a primary adenoid cystic carcinoma. The tumor was about 3 cm in size and invaded about 1 cm of the lower trachea, 2 cm of the left main bronchus (LMB), and 1 cm of the right main bronchus (RMB), blocking about 70% of the tracheal lumen, 90% of the LMB, and 50% of the RMB.

U-shaped association between hemoglobin levels and albuminuria in US adults: a cross-sectional study.

Purpose: This study aimed to explore the correlation between hemoglobin levels and albuminuria in US adults.

Methods: This cross-sectional investigation analyzed the National Health and Nutrition Examination Survey (NHANES) information from 2011 to 2020. Data on hemoglobin, albuminuria, and other variables were collected from all participants.

Fallopian tube cancer with inguinal lymph node metastasis as the first symptom: A case study and review of the literature.

Introduction And Importance: Fallopian tube cancer that is characterized only by inguinal lymph node metastasis without intra-abdominal widespread is rare. Here we report a patient with primary Fallopian tube cancer with bilateral inguinal metastases as the first symptom.

Case Presentation: A 68-year-old patient with primary Fallopian tube cancer, with painless bilateral inguinal enlargement (7 × 6 cm on the right side, 3 × 2 cm on the left side) as the only manifestation, was confirmed by preoperative biopsy as metastatic high-grade serous denocarcinoma, consider the adnexal or peritoneal source.

The value of G-CSF in women experienced at least one implantation failure: a systematic review and meta-analysis.

Objective: Despite the developments of fertilization (IVF) protocols, implantation failure remains a challenging problem, owing to the unbalance between the embryo, endometrium, and immune system interactions. Effective treatments are urgently required to improve successful implantation. Recently, many researchers have focused on granulocyte colony-stimulating factor (G-CSF) to regulate immune response and embryo-endometrium cross-talk.
