Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Indwelling urinary catheterization is one of the most widely used invasive procedures in clinical practice, playing a critical role in disease diagnosis, treatment, and monitoring. In 2024, the European Association of Urology Nurses (EAUN) released the Best Practice Guidelines for Indwelling Urinary Catheterization in Adults-Transurethral and Suprapubic Catheterization (hereinafter referred to as the Guideline), aiming to provide evidence-based clinical guidance and health education information for healthcare professionals. This article interprets the section on "Nursing Principles" within the Guideline, which spans the entire process of catheter management. Key aspects covered include pre-insertion preparation, catheter insertion procedure, catheter maintenance and securement, observation of urine color, prevention of constipation, and catheter removal. The aim is to help urology nurses and related healthcare personnel gain an in-depth understanding of the recommendations in the Guideline, promote its standardized application in clinical practice, improve the quality of indwelling catheter care, and ensure patient safety.

To evaluate the value of forward-return way in endoscopic resection for the treatment of gastric fundus stromal tumor, patients with gastric fundus stromal tumor in muscularis propria diagnosed by endoscopy and endoscopic ultrasonography at the Department of Digestive Endoscopy of the Fourth Affiliated Hospital of China Medical University from June 2020 to June 2021 were prospectively enrolled in the study. All patients were treated with endoscopic full-thickness resection under general anesthesia with endotracheal intubation. The success of forward-return way, endoscopic procedure, operation performance, pathological classifications and complications were analyzed. A total of 12 patients were enrolled. All of them were confirmed as having stromal tumor by postoperative pathology, with 10 of very low risk and 2 of low risk. Forward-return way was successful in 9 patients and failed in 3 patients. Nine patients were successfully treated with endoscopic procedure eventually. No intraoperative bleeding occurred in any patient. In endoscopic resection, the scores of same direction of forward and backward, endoscopic field of view, and endoscopic body stability were all 2.00 points. Forward-return way has clinical application value for the endoscopic treatment of gastric fundus stromal tumor.

This study examined the mechanism by which the gastric cancer cells lead to early peritoneal metastasis. HMrSV5 cells, a human peritoneal mesothelial cell line, were co-incubated with the supernatants of gastric cancer cells. Morphological changes of HMrSV5 cells were observed. The cell damage was quantitatively determined by MTT assay. The apoptosis of HMrSV5 cells was observed under transmission electron microscope. Acridine orange/ethidium bromide-stained condensed nuclei was detected by fluorescent microscopy and flow cytometry. The expressions of Bcl-2 and Bax was immunochemically evaluated. The results showed that conspicuous morphological changes of apoptosis were observed in HMrSV5 cells 24 h after treatment with the supernatants of gastric cancer cells. The supernatants could induce apoptosis of HMrSV5 cells in a time-dependent manner. The supernatants could up-regulate the expression of Bax and suppress that of Bcl-2 in HMrSV5 cells. These findings demonstrated that gastric cancer cells can induce the apoptosis of HPMCs through supernatants in the early peritoneal metastasis. The abnormal expressions of Bcl-2 and Bax may contribute to the apoptosis. Anti-apoptosis drugs promise to be adjuvant chemotherapeutic agents in the treatment of peritoneal metastasis of gastric cancer.
