Comprehensive study of gene fusions in sarcomas.

Sarcomas, including bone sarcomas and soft tissue sarcomas (STSs), are a heterogeneous group of mesenchymal malignancies. Recent advancements in next-generation sequencing (NGS) have enabled the identification of novel chromosomal translocations and fusion genes, which play a critical role in sarcoma subtypes. Our study focuses on gene fusions in sarcomas among Chinese patients, comparing their genomic profiles to those of Western populations.

We report a case of a 72-year female with erythematous pemphigus who developed erythema, swelling and ulceration on right vulva, groin, and thigh. The early clinical manifestations of the patient were nonspecific and easily misdiagnosed as cellulitis.

Sequential Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitor-Induced Radical Surgery in Oligometastatic Non-Small Cell Lung Cancer: A Case Report.

Sequential regimens in patients with epidermal growth factor receptor (EGFR) mutation-positive non-small cell lung cancer (NSCLC) can overcome tyrosine kinase inhibitor (TKI) resistance and maximize clinical benefit. Patients with advanced NSCLC can achieve excellent tumor control after a period of EGFR-TKI treatment. Patients may benefit from additional local treatment, such as surgery or radiation therapy, once the tumor is under control.

Molecular profiling and prognostic analysis in Chinese cholangiocarcinoma: an observational, retrospective single-center study.

The study aimed to improve the understanding of molecular characteristics and its association with prognosis in Chinese CCA.

Favorable impact of a novel endoscopic auxiliary system (NEAS) on fluoroscopy-guided lithotripsy for difficult bile duct stones: A pilot study.

Objectives: Laser lithotripsy under fluoroscopic guidance is difficult to perform and risky due to its invisibility. In this study we aimed to investigate the efficacy and safety of a novel endoscopic auxiliary system (NEAS)-assisted lithotripsy under fluoroscopy for treating difficult common bile duct (CBD) stones.

Methods: Patients with difficult CBD stones who were treated with NEAS-assisted laser lithotripsy (NEAS group) or conventional mechanical lithotripsy (ML) under fluoroscopy (ML group) were retrospectively evaluated.

Pharmacodynamic study of chitosan in combination with salvianolic acid B in the treatment of CC1 -induced liver fibrosis in mice.

Liver fibrosis is a chronic liver lesion caused by excessive deposition of the extracellular matrix after liver damage, resulting in fibrous scarring of liver tissue. The progression of liver fibrosis is partially influenced by the gut microbiota. Chitosan can play a therapeutic role in liver fibrosis by regulating the gut microbiota based on the 'gut-liver axis' theory.

Comprehensive genomic analysis of primary bone sarcomas reveals different genetic patterns compared with soft tissue sarcomas.

Introduction: Sarcomas are classified into two types, bone sarcoma and soft tissue sarcoma (STS), which account for approximately 1% of adult solid malignancies and 20% of pediatric solid malignancies. There exist more than 50 subtypes within the two types of sarcoma. Each subtype is highly diverse and characterized by significant variations in morphology and phenotypes.

Case report: Unique FLT4 variants associated with differential response to anlotinib in angiosarcoma.

CMI was measured and statistical analysis was performed to determine the optimal threshold for predicting acute exacerbation of chronic obstructive pulmonary disease.

Molecular and clinicopathological characteristics of gene fusions in 32,131 Chinese patients with solid tumors.

amplification is one of the most important and mature targets for HER2-targeted drug therapy. Somatic mutations of in the tyrosine kinase domain have been studied extensively, and play a role in response to anti-HER2 therapy among different cancer types. However, fusion has not been got attention and its relevance to HER2-targeted therapy is unclear.

The Effect of Teach-Back Combined with King Interactive Standard Mode on the Life of COPD Patients.

Background: COPD is a common clinical chronic airway inflammatory disease that occurs mostly in middle-aged and older adults over the age of 40. The incidence of COPD is increasing year by year and the onset of age is gradually becoming younger.

Objective: To observe the effect of teach-back combined with king interaction on the life of patients with chronic obstructive pulmonary disease (COPD).

The entry of unclosed autophagosomes into vacuoles and its physiological relevance.

It is widely stated in the literature that closed mature autophagosomes (APs) fuse with lysosomes/vacuoles during macroautophagy/autophagy. Previously, we showed that unclosed APs accumulated as clusters outside vacuoles in Vps21/Rab5 and ESCRT mutants after a short period of nitrogen starvation. However, the fate of such unclosed APs remains unclear.

Study on the Mental Health Service Behavior of Medical Staff Based on Electrocardiogram.

Acquired Immune Deficiency Syndrome (AIDS) is a fatal infectious disease caused by human immunodeficiency virus, which poses a serious threat to human health. The contagion of AIDS has greatly increased the psychological pressure of frontline medical staff. The mental health service behavior of medical staff based on electrocardiograms is analyzed.

Vps21 Directs the PI3K-PI(3)P-Atg21-Atg16 Module to Phagophores via Vps8 for Autophagy.

Phosphatidylinositol 3-phosphate (PI(3)P) serves important functions in endocytosis, phagocytosis, and autophagy. PI(3)P is generated by Vps34 of the class III phosphatidylinositol 3-kinase (PI3K) complex. The Vps34-PI3K complex can be divided into Vps34-PI3K class II (containing Vps38, endosomal) and Vps34-PI3K class I (containing Atg14, autophagosomal).

Case report: Identification of a novel heterozygous germline mutation in a patient with dermatofibrosarcoma protuberans.

Dermatofibrosarcoma protuberans (DFSP) is a kind of soft tissue sarcoma, mostly occurs in the trunk, followed by proximal extremities and head and neck. Surgical resection is the most important treatment for DFSP, but the local recurrence rate of DFSP is high. Except reported specific chromosomal tran7slocations occurred in DFSP, the association between DNA repair gene mutations and DFSP still unknown.

A novel TMTC2-NTRK3 fusion in undifferentiated high-grade pleomorphic sarcoma.

Undifferentiated high-grade pleomorphic sarcoma (UHPS) is a rare soft tissue sarcoma (STS) originated from mesenchyme. UHPS is mostly advanced, aggressive and has poor prognosis. Patients with UHPS tend to have a lower 5-year survival rate than patients with other types of STS.

Yeast phospholipase D, Spo14, is not required for macroautophagy.

Autophagy-related gene (Atg) proteins are key players in autophagy. Some proteins that function in vesicle trafficking and lipid metabolism are also involved in autophagy. The SPO14 in yeast, which encodes phospholipase D (PLD), is involved in membrane trafficking and plays a vital role in sporulation during meiosis.

Immune Checkpoint Blockade in Chinese Patients With Hepatocellular Carcinoma: Characteristics and Particularity.

More than half of new cases of hepatocellular carcinoma (HCC) and associated deaths occurring annually worldwide are recorded in China. Chinese patients with HCC exhibit special characteristics in terms of etiology, leading to differences in prognosis versus Western patients. In recent years, several angiogenesis inhibitors were approved, and immune checkpoint blockers (ICBs) were recommended as second-line therapy for advanced HCC.
