Background: The purpose of this study was to investigate the effect of a simple laparoscopic common bile duct exploration (LCBDE) simulator and corresponding practicing program on the application of performing LCBDE in a low volume center.
Methods: A retrospective review was performed by analyzing data from the electronic medical record for 4118 patients with choledocholithiasis in Changxing County Hospital (Huzhou, Zhejiang, China) between January 2013 and December 2018. From January 2016, we have developed a simple LCBDE-specific simulator and corresponding practicing program in our hospital. The percentage of patients with choledocholithiasis managed by LCBDE before and after the introduction of a simple LCBDE-specific simulator and corresponding practicing program was compared.
Results: There were 8.9% (367/4118) patients with a diagnosis of choledocholithiasis confirmed by MRCP. Single-stage management with LC+LCBDE was performed in 23.7% (87/367) patients. Among them, 23 cases were performed between January 2013 and December 2015, and 64 cases were performed between January 2016 and December 2018. The introduction of simulator-enhanced practicing program in January 2016 has resulted in an increase in the percentage of performed LCBDE, from 12.9% to 33.9%. In addition, there was an 29.5% reduction in the mean operating time (from 193 min to 136 min) needed for LCBDE with T-tube when compared these two periods.
Conclusions: LCBDE simulator can improve the application in a low volume center, and help to increase the utilization of this effective, one stage treatment for choledocholithiasis and reduce the need for costlier ERCP.

Identifying novel, high-yield drug targets is challenging and often results in a high failure rate. However, recent data indicates that leveraging human genetic evidence to identify and validate these targets significantly increases the likelihood of success in drug development. Two recent papers from Open Targets claimed that around half of FDA-approved drugs had targets with direct human genetic evidence.

The type I interferon (IFN-I) response is a critical component of the immune defense against various viral pathogens, triggering the expression of hundreds of interferon-stimulated genes (ISGs). These ISGs encode proteins with diverse antiviral functions, targeting various stages of viral replication and restricting infection spread. Beyond their antiviral functions, ISGs and associated immune metabolites have emerged as promising broad-spectrum biomarkers that can differentiate viral infections from other conditions.

Non-viral vectors have gained recognition for their ability to enhance the safety of gene delivery processes. Among these, polyethyleneimine (PEI) stands out as the most widely utilized cationic polymer due to its accessibility. Traditional methods of modifying PEI, such as ligand conjugation, chemical derivatization, and cross-linking, are associated with intricate preparation procedures, limited transfection efficiency, and suboptimal biocompatibility.

Psoriasis, a chronic inflammatory dermatosis, represents a significant clinical challenge due to its complex pathogenesis and the limitations of existing therapeutic strategies. Current psoriasis diagnoses are primarily clinician-dependent, with instrumental diagnostics serving as adjuncts. Ongoing research is progressively deciphering its molecular underpinnings; the future of psoriasis diagnostics may involve genetic and immunological profiling to pinpoint biomarkers, enabling more accurate and timely interventions.

Proline, a critical osmoregulatory compound, is integral to various plant stress responses. The gene, which encodes the rate-limiting enzyme in proline biosynthesis, known as ∆1-pyrroline-5-carboxylate synthetase, is fundamental to these stress response pathways. While the functions of genes in plants have been extensively documented, their specific roles in cotton remain inadequately characterized.
