Background Laparoscopy-assisted radical gastrectomy is gaining acceptance for treating early gastric cancer. However, few reports concerning the effectiveness of laparoscopy-assisted D2 radical distal gastrectomy （LADG） for advanced gastric cancer or data comparing the results obtained after open distal gastrectomy （ODG） are yet available. The aim of this study was to evaluate the method, feasibility and clinical result of LADG for advanced gastric cancer. Methods A retrospective study was performed comparing LADG and ODG for advanced gastric cancer. Seventy-eight patients who underwent LADG were compared with 90 patients who underwent ODG in terms of pathologic findings, operative outcome, and complications. Results There was no conversion to open surgery in the LADG group and no postoperative mortality of any patients. There were no significant differences between LADG and ODG in operative time （（245±35） vs （220±620） minutes）, complication rate （7.7% vs 10.0%）, and number of lymph nodes （23.5±6.0 vs 21.0±7.5）, while the blood loss was less after LADG （（110±25） vs （196±30） ml, P 〈0.05）. The time to postoperative flatus and postoperative hospital stay were shorter after LADG （（73.0±8.5） vs （102.0±10.5） hours, and （8.6±1.2） vs （12.1 ±2.5） days, P 〈0.05, respectively）. Conclusion LADG for advanced gastric cancer is feasible, safe, and minimally invasive.

Methane, an abundant one-carbon（C1） resource, is extensively used in the industrial production of vital fuels and value-added chemicals. However, current industrial methane conversion technologies are energy-and carbon-intensive, mainly due to the high activation energy required to break the inert C–H bond, low selectivity, and problematic side reactions, including CO2emissions and coke deposition. Electrochemical conversion of methane（ECM） using intermittent renewable energy offers an attractive solution, due to its modular reactor design and operational flexibility across a broad spectrum of temperatures and pressures. This review emphasizes conversion pathways of methane in various reaction systems, highlighting the significance and advantages of ECM in facilitating a sustainable artificial carbon cycle. This work provides a comprehensive overview of conventional methane activation mechanisms and delineates the complete pathways of methane conversion in electrolysis contexts. Based on surface/interface chemistry, this work systematically analyzes proposed reaction pathways and corresponding strategies to enhance ECM efficiency towards various target products, including syngas, hydrocarbons, oxygenates, and advanced carbon materials. The discussion also encompasses opportunities and challenges for the ECM process, including insights into ECM pathways, rational electrocatalyst design, establishment of benchmarking protocols, electrolyte engineering, enhancement of CH4conversion rates, and minimization of CO2emission.

Ovarian endometrioma（OE）, also known as “chocolate cysts,” is a cystic mass that develops in the ovaries due to endometriosis and is a common gynecological condition characterized by the growth of endometrial tissue outside the uterus, leading to symptoms such as dysmenorrhea, pelvic pain, and infertility. However, the precise molecular and cellular mechanisms driving this pathophysiology remain largely unknown, posing challenges for diagnosis and treatment. Here, we employed integrated single-cell transcriptomic profiling of over 52,000 individual cells from endometrial tissues of OE patients and healthy donors and identified twelve major cell populations. We identified notable alterations in cell type-specific proportions and molecular signatures associated with OE. Notably, the activation of IGFBP5+macrophages with pro-inflammatory properties, NK cell exhaustion, and aberrant proliferation of IQCG+and KLF2+epithelium are key features and may be the potential mechanisms underlying the pathogenesis of OE. Collectively, our data contribute to a better understanding of OE at the single cell level and may pave the way for the development of novel therapeutic strategies.
