Abstract Peritoneal metastasis (PM) is considered one of the most dreaded forms cancer metastases for both patients and physicians. Aggressive cytoreductive surgery (CRS) primary treatment peritoneal metastasis. Unfortunately, this intensive frequently causes clinical complications, such as postoperative recurrence, metastasis, adhesion formation. Emerging evidence suggests that neutrophil extracellular traps (NETs) released by inflammatory neutrophils contribute to these complications....

Abstract Pyogenic liver abscess (PLA) is a common intra-abdominal infection in adults. In this study, we aim to explore demographic and clinical characteristics of PLA focusing on Klebsiella pneumoniae (K. ) induced (KP-PLA) mainland China. A retrospective review medical records from all patients with KP-PLA admitted tertiary teaching hospital over 21-year period (1994–2015) was performed. Among 296 cases confirmed culture-positive data, K. revealed as the predominant pathogen ( n = 189,...

Nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used but often cause small intestinal ulcers (SIUs), for which effective therapies lacking. Sishen Pill (SSP), a traditional Chinese medicine, shows therapeutic promise, yet its mechanisms remain unclear. This study integrates network pharmacology, molecular docking, and experimental validation to systematically investigate SSP's protective against NSAID-induced SIUs. Active SSP ingredients were screened using the Traditional Medicine...

With an increasing trend of patients with young-onset colorectal cancer (CRC), risks second primary cancers (SPCs) among them become a concerning issue. We aimed to define the detailed risk and site-distributed patterns SPCs in young CRC individuals (age ≤50). A population-based cohort were identified from Surveillance, Epidemiology, End Results database between 1973 2013. Standardized incidence ratios (SIRs) absolute excess (AER) calculated assess for compared general population. total...

Though methods for the diagnosis of pancreatic masses are various, such as ultrasonography (US), computed tomography (CT), endoscopic (EUS), and contrast-enhanced (CE-CT), their sensitivity, specificity, accuracy not quite satisfying. Contrast-enhanced (CE-EUS), a new technique, has its own unique advantages in diagnosing disease. However, still controversial. To evaluate CE-EUS differential between benign malignant mass lesions. Eighteen relevant articles systemically searched from PubMed,...

During liver regeneration after partial hepatectomy, the function and metabolic pathways governing transient lipid droplet accumulation in hepatocytes remain obscure. Mammalian target of rapamycin 2 (mTORC2) facilitates de novo synthesis hepatic lipids. Under normal conditions tumorigenesis, decreased levels triglyceride (TG) fatty acids (FAs) are observed mTORC2-deficient liver. However, during regeneration, their increase absence mTORC2.Rictor liver-specific knockout control mice underwent...

Abstract Apoptosis is a dynamic process regulated by mitochondrion critical for cellular respiration and survival. Execution of apoptosis mediated multiple protein signaling events at mitochondria. Initiation progression require numerous apoptogenic factors that are either released from or sequestered in mitochondria, which may transform the biomolecular makeup organelle. In this communication, using Raman microspectroscopy, we demonstrate transformation composition be used as marker an...

Alcohol, tobacco smoke and Barrett's oesophagus as a consequence of gastro-oesophageal reflux are the main risk factors in oesophageal carcinogenesis. All may induce oxidative stress. Manganese superoxide dismutase (MnSOD) is one important repair enzyme for reactive stress (ROS)-induced damage. MnSOD polymorphisms -9 position signal sequence protein lead to critical deficiency.
