Background: Lysosome is a highly heterogeneous membranous organelle in eukaryotic cells, which regulates many physiological processes in the cell. Studies have found that lysosomal dysfunction disrupts cellular homeostasis and is associated with Parkinson's disease (PD). Transmembrane protein 175 (TMEM175) is a lysosomal cation channel whose activity is essential for lysosomal homeostasis.

This case highlights the effective use of retroperitoneal laparoscopic partial nephrectomy (RLPN) in a 73-year-old female with two large renal carcinomas in her solitary kidney, including a 7 cm deeply infiltrating mass. The RLPN procedure successfully resected both tumors with a thermal ischemia time of 28 minutes, 110 minutes of surgery, and only 30 mL of blood loss. The patient's postoperative recovery was excellent, with no hemorrhage or urine leakage and only a mild increase in serum creatinine levels.

Esmolol has been demonstrated to mitigate inflammation damage and T lymphocyte apoptosis in septic cardiomyopathy. It has been established that the activation of α7 nicotinic acetylcholine receptor (nAChR) by cluster of differentiation 4(CD4) T lymphocytes expressing choline acetyltransferase (ChAT) can prevent excessive inflammation and reduce splenocyte apoptosis in septic cardiomyopathy. Given the similar anti-inflammatory effects, we hypothesized that esmolol might be associated with α7 nAChR and thereby exert its cardioprotective functions.

Objectives: To analyze the association of CHMP2B expression level of with clinicopathological characteristics and prognosis of clear cell renal cell carcinoma (CRCC) and the possible role of CHMP2B in tumorigenesis and progression of CRCC.

Methods: RNAseq data of CRCC were downloaded from the TCGA database for analysis of CHMP2B expression levels in tumor and adjacent tissues and their correlation with clinicopathological characteristics of the patients. Survival outcomes of the patients with high and low CHMP2B expressions were analyzed using the Kaplan-Meier model, and the COX risk regression model was used for identifying the prognostic factors of the patients.

Purpose: To evaluate the efficacy and safety of induction chemotherapy combined with programmed death protein 1 (PD-1) inhibitor (sintilimab) followed by concurrent chemoradiotherapy (CCRT) plus sintilimab, and subsequent maintenance with sintilimab (IC-ICCRT-IO) for patients with unresectable locally advanced esophageal squamous cell carcinoma (ESCC) in a retrospective study.

Methods: Data from patients with histologically confirmed, locally advanced, inoperable ESCC who received IC-ICCRT-IO were retrospectively analyzed. Treatment effects were evaluated after 2 cycles of induction therapy and after CCRT by contrast-enhanced CT scans and esophagograms, followed by subsequent evaluations every 3 months post-treatment.

Background: Esophagojejunal anastomotic fistula (EJF) following radical total gastrectomy is a severe perioperative complication in patients with gastric cancer, particularly as delayed fistula healing increases hospitalization costs and leads to poor prognosis. Numerous factors influence the occurrence and progression of EJF, with inflammation and nutritional status being significant contributors to perioperative complications. Therefore, this study aims to investigate the prediction of delayed EJF healing based on postoperative clinical and imaging-related inflammation-nutrition status.
