Effect of Low Molecular Weight Heparin Calcium on Prevention of Lower Limb Deep Venous Thrombosis in Oral Cancer Patients With Anterolateral Thigh Flap Reconstruction.

Background: This study aimed to evaluate the effect of low molecular weight heparin calcium (LMWH-Ca) on the prevention of deep venous thrombosis (DVT) in patients with anterolateral thigh (ALT) flap reconstruction.

Methods: In total, 1001 patients with oral cancer who underwent ALT flap reconstruction were recruited. Based on the postoperative use of LMWH-Ca, the patients were divided into case (n = 633) and control groups (n = 368).

Spatial Transcriptomic and Metabolomic Landscapes of Oral Submucous Fibrosis-Derived Oral Squamous Cell Carcinoma and its Tumor Microenvironment.

In South and Southeast Asia, the habit of chewing betel nuts is prevalent, which leads to oral submucous fibrosis (OSF). OSF is a well-established precancerous lesion, and a portion of OSF cases eventually progress to oral squamous cell carcinoma (OSCC). However, the specific molecular mechanisms underlying the malignant transformation of OSCC from OSF are poorly understood.

Spatially Resolved Transcriptomics Technology Facilitates Cancer Research.

Single cell RNA sequencing (scRNA-seq) provides a great convenience for studying tumor occurrence and development for its ability to study gene expression at the individual cell level. However, patient-derived tumor tissues are composed of multiple types of cells including tumor cells and adjacent non-malignant cells such as stromal cells and immune cells. The spatial locations of various cells in situ tissues plays a pivotal role in the occurrence and development of tumors, which cannot be elucidated by scRNA-seq alone.

Potential applications of N -methyladenosine modification in the prognosis and treatment of cancers via modulating apoptosis, autophagy, and ferroptosis.

N -methyladenosine (m A) is one of the most abundant modifications determining the fate of RNA. Currently, m A modification is tightly connected with tumorigenesis and presents novel promise in clinical applications. Regulated cell death (RCD) is a programmed mechanism that plays a complicated role in malignant transition.

Reconstruction of Complex Lateral Skull Base Defects After Oral Cancer Resection With Individualized Anterolateral Thigh Flap.

Objectives: Complex lateral skull base defects resulting from advanced or recurrent oral cancer resection are continuously challenging reconstructive surgeons. This study aimed to use reconstructive methods for lateral skull base defects, explore their feasibility, and evaluate the efficacy of defect reconstruction using anterolateral thigh (ALT) flaps.

Patients And Methods: We performed a retrospective case series of 37 patients who underwent lateral skull base defect reconstruction using the ALT/anteromedial thigh (AMT) flap between March 2016 and May 2021 at the Second Xiangya Hospital.
