Gastric cancer remains a highly prevalent malignancy worldwide, with surgical resection currently constituting the cornerstone of treatment aimed at improving long-term patient survival. Owing to their notable advantages, including reduced surgical trauma and accelerated postoperative recovery, minimally invasive procedures are progressively supplanting conventional open surgery and have become the mainstream approach in gastric cancer management. Concurrently, the rapid advancement of artificial intelligence (AI) technologies has enabled real-time intraoperative monitoring of surgical scenes, thereby furnishing novel technical support for adjunctive decision-making, surgical navigation, and skill assessment during gastrectomy. This article provides a systematic review of the current status of AI applications in minimally invasive gastric cancer surgery, with a particular focus on research progress pertaining to instrument recognition, surgical phase identification, delineation of normal anatomical structures, detection of metastatic foci, and early warning of intraoperative adverse events. Furthermore, we discuss the potential value of AI in enhancing surgical efficiency, ensuring patient safety, and optimizing surgical education. On this basis, we further analyze the principal challenges and inherent risks confronting current AI systems, with the aim of informing future technological innovation and facilitating clinical translation.

BACKGROUND/AIMS: In recent years, endoscopic submucosal tunnel dissection (ESTD) has gained popularity worldwide. The aim of this study was to evaluate the safety and efficacy of ESTD in treating upper gastrointestinal submucosal tumors (SMTs) in a large-volume endoscopic center. METHODS: Patients with SMTs were enrolled in this study between January 2012 and January 2015. Demographic data, clinical data, and treatment outcome were collected and analyzed. RESULTS: Seventy SMTs originating from the muscularis propria (MP) layer were identified in 69 patients. All patients successfully underwent the ESTD procedure. The mean procedure time was 49.0±29.5 minutes, and the mean tumor size was 18.7±7.2 mm. Among all lesions, the majority (70.0%) were located in the esophagus, 12.9% in the cardia, and 17.1% in the stomach. Complete resection was achieved in 67 lesions (95.7%). Perforation occurred in three patients (4.3%), who were treated by endoclips. Pneumothorax occurred in two patients (2.9%) and was successfully managed by thoracic drainage. During a median follow-up of 18.1 months, patients were free of local recurrence or distant metastasis. CONCLUSIONS: Our results demonstrated the feasibility and safety of ESTD in treating upper gastrointestinal SMTs originating from the MP layer. Large-scale comparative studies with other treatment methods should be conducted in the future.

Objective To investigate the epidemiological characterization , effect of prevention and control measures during an outbreak in a military unit caused by Mycoplasma pneumoniae.Methods All the cases were investigated to learn about their basic characteristics , clinical symptoms and aggregation activities using epidemiological cross-sectional study . Results From May 16 to June 11,2013, forty-nine confirmed cases and thirty-five suspected cases who were all males were found at an attack rate of 7.8%.The epidemic peak period was from May 27 to Jun 2(seven days), and the number of total cases was 66(75.9%).During the outbreak, the attack rate of the 10th cadet team, other cadet teams and a non-student population was 47.5%, 4.5% and 1.2% respectively.The difference was significant (P<0.01).The age of forty-nine confirmed cases ranged from 17 to 26 years old , the attack rate did not differ significantly between different age groups, and no aggregation was found in the place of birth and soldier source .The most frequent clinical symptoms were fever and cough for the confirmed cases , 62.5% of whom showed unilateral or bilateral lung inflammation change , while few positive lung symptoms were present .All the confirmed cases were hospitalized and no severe or critically ill cases were present.The outbreak was controlled effectively after implementation of case surveillance , contact precaution , termination of aggregation activities , dispersed habitation and prescription of azithromycin for disease prevention .Conclusion The confined and crowed environment for learning and training can increase the risk of M.pneumoniae outbreak , making it nec-essary to enhance disease prevention awareness , improve case management , live dispersed , reduce close contact and imple-ment personal hygienic measures .

OBJECTIVE: To improve the checking management of outpatient pharmacy and to reduce the error rates of checking process. METHODS: With the data from "Army No 1" hospital information system, to designe dynamic checking table ordered by fixed location of each drugs in containers, and pending prescription transfer database is established to manage unconfirmed expired prescriptions. RESULTS & CONCLUSIONS: The order of name in the stock table of drugs is identified to the position of each drug in containers. There is no requirement for incorporate check-in operation of the same kind of drugs from various manufactories and identification of their locations. Taken advantage of computer technology, this checking program is more time-saving, simple and easy, and significantly increases the accuracy of results.
