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.

Objective To investigate the detection rate and related influencing factors of gastrointestinal diseases in grass-roots personnel.Methods A total of 481 grass-roots personnel were enrolled and examined by magnetic-controlled capsule endoscopy(MCCE).Multivariate logistic regression were used to analyze the influencing factors of gastrointestinal diseases detected by MCCE.Results All personnel completed MCCE,and gastrointestinal diseases were detected in 154(32.0%)cases,including 106 cases of erosive gastritis,25 cases of chronic atrophic gastritis,17 cases of digestive tract polyp,16 cases of gastric ulcer,5 cases of reflux esophagitis,4 cases of cardia,1 case of duodenitis,and 1 case of enteritis.Gastrointestinal diseases was correlated with special operation posts,long-term tasks within recent 6 months,abdominal distension,belching,nausea and vomiting,diarrhea and other symptoms(all P＜0.05).Multivariate logistic regression analysis showed that the risk factors of gastrointestinal diseases were working in special operation posts,performing long tasks within 6 months,belching,nausea and vomiting symptoms(all P＜0.05).Conclusion The overall detection rate of gastrointestinal diseases(mainly acid related diseases)is relatively high,and its incidence is closely related to working in special operation posts and performing long-term tasks within recent 6 months.Personnel working in special operation posts should be more alert to gastrointestinal diseases.Gastrointestinal symptoms have reference value for the prediction of lesions,but more attention should be paid to the identification of functional gastrointestinal diseases with endoscopy.

Objective To compare the effects of desflurane inhalation anesthesia versus propofol total intravenous anesthesia on postoperative recovery quality in patients undergoing endoscopic transnasal pituitary adenoma resection,and to provide evidence-based recommendations for optimizing anesthetic management in this surgical population.Methods This single-center,prospective,randomized controlled trial enrolled 112 patients scheduled for endoscopic transnasal pituitary adenoma resection,who were randomly assigned to either the desflurane group(n=56)or the propofol group(n=56).The desflurane group received desflurane[0.7-1.0 minimum alveolar concentration(MAC)]combined with remifentanil for anesthesia maintenance,whereas the propofol group received propofol(4-6 mg·kg-1·h-1)with remifentanil.The primary outcome was defined as the time from discontinuation of anesthetics to achieving an Aldrete score of 9.Secondary outcomes included emergence time,extubation time,and incidences of postoperative agitation and vomiting.Results Patients receiving desflurane achieved an Aldrete score of 9 significantly faster than those in the propofol group(13.0 min vs 16.5 min,P=0.003).Similarly,both emergence time(14.0 min vs 16.5 min,P=0.009)and extubation time(13.0 min vs 16.5 min,P=0.003)were significantly shorter in the desflurane group.However,the desflurane group had higher incidences of postoperative agitation(17.9%vs 3.6%,P=0.015)and vomiting(19.6%vs 5.4%,P=0.022).No significant difference was observed in severe agitation rates or 24 h postoperative recovery quality[Quality of Recovery-15(QoR-15)scores]between groups.Conclusion Desflurane anesthesia significantly accelerates postoperative recovery in patients undergoing endoscopic transnasal pituitary adenoma resection,however,it may increase risks of mild agitation and vomiting.In clinical applications,it is necessary to balance recovery benefits against potential adverse effects,and take targeted prophylactic measures.

Objective:To investigate the association of urinary cadmium level with body mass index (BMI) and body circumferences among the older adults over 65 years old in 9 longevity areas of China.Methods:Subjects were older adults over 65 years old from the Healthy Aging and Biomarkers Cohort Study (HABCS) between 2017 and 2018 conducted in 9 longevity areas in China. A total of 1 968 older adults were included in this study. Information including socio-demographic characteristics, lifestyles, diet intake, and health status was collected by using questionnaires and physical examinations. Urine samples were collected to detect urinary cadmium and creatinine levels. Body circumferences included waist circumference, hip circumference and calf circumference. Subjects were divided into three groups (low:<0.77 μg/g·creatinine, middle:0.77-1.69 μg/g·creatinine, high:≥1.69 μg/g·creatinine) by tertiles of creatinine-adjusted urinary cadmium concentration. Multiple linear regression models were used to analyze the association of creatinine-adjusted urinary cadmium level with BMI and body circumferences. The dose-response relationship of creatinine-adjusted urinary cadmium concentration with BMI and body circumferences was analyzed by using restrictive cubic splines fitting multiple linear regression model.Results:The mean age of subjects was (83.34±11.14) years old. The median (Q1, Q3) concentration of creatinine-adjusted urinary cadmium was 1.13 (0.63, 2.09) μg/g·creatinine, and the BMI was (22.70±3.82) kg/m 2. The mean values of waist circumference, hip circumference, and calf circumference were (85.42±10.68) cm, (92.67±8.90) cm, and (31.08±4.76) cm, respectively. After controlling confounding factors, the results of the multiple linear regression model showed that for each increment of 1 μg/g·creatinine in creatinine-adjusted urinary cadmium, the change of BMI, waist circumference, hip circumference, and calf circumference in the high-level group was -0.28 (-0.37, -0.19) kg/m 2, -0.74 (-0.96, -0.52) cm, -0.78 (-0.96, -0.61) cm, and -0.20 (-0.30, -0.11) cm, respectively. The restrictive cubic splines curve showed a negative nonlinear association of creatinine-adjusted urinary cadmium with BMI ( Pnonlinear<0.001) and negative linear associations of creatinine-adjusted urinary cadmium with waist circumference ( Plinear<0.001), hip circumference ( Plinear<0.001), and calf circumference ( Plinear<0.001). Conclusion:Urinary cadmium level is significantly associated with decreased BMI, waist circumference, hip circumference and calf circumference among older adults over 65 years old in 9 longevity areas of China.

Objective To investigate the effect of N6-methyladenosine (m⁶A) reading protein human antigen R (HuR) on the migration, invasion and glycolysis of colorectal cancer cells and its relationship with 6-phosphofructokinase 1 (PFK1). Methods The tissue samples of 33 patients who were first diagnosed as colorectal cancer in Zhengzhou Central Hospital Affiliated to Zhengzhou University from April to December 2022 were collected. Real-time fluorescent quantitative polymerase chain reaction (qRT-PCR) was used to detect the expression levels of HuR and PFK1 mRNA in colorectal cancer tissues and adjacent tissues. The expression of HuR mRNA in normal intestinal epithelial cells NCM460 and colorectal cancer cells HCT8, SW480, SW620, HCT116, LoVo, RKO and COLO205 was detected. Small interfering RNA (siRNA) was used to construct a HuR knockdown colorectal cancer cell model. The effects of HuR on the migration and invasion of colorectal cancer cells were detected by cell scratch assay and Transwell assay. The expression of PFK1 mRNA and protein was detected by qRT-PCR and Western blot. Glucose intake and pyruvate production were detected by glucose content kit and pyruvate content kit, respectively. The relationship between HuR and PFK1 was analyzed by bioinformatics analysis, and the effect of HuR on the stability of PFK1 mRNA was evaluated by actinomycin D assay. Results In colorectal cancer tissues, HuR and PFK1 were highly expressed at mRNA level; HuR was highly expressed at mRNA level in colorectal cancer cell lines. Down-regulation of HuR significantly inhibited the migration and invasion of colorectal cancer cells, as well as glucose consumption and pyruvate production. Knockdown of HuR could reduce the stability of PFK1 mRNA and its expression at mRNA and protein levels. There were m⁶A modification sites on PFK1. Conclusion The m⁶A reading protein HuR may regulate the migration, invasion and glycolysis of colorectal cancer cells by recognizing the m⁶A site on PFK1 and reducing the stability of PFK1 mRNA.

Objective To compare the effectiveness of Defocus Incorporated Multiple Segments (DIMS) and High Aspheric Lenslet (HAL) defocus lenses in controlling myopia. Methods A total of 214 children and adolescents who were fitted with defocus lenses (DIMS or HAL) in our hospital from January to June 2023 were selected, including 100 cases in DIMS group and 114 cases in the HAL group. Changes in parameters such as spherical lens power, cylindrical lens power, spherical equivalent (SE), corneal curvature (K), axial length (AL), binocular accommodative response (BCC), positive/negative relative accommodation (PRA/NRA), distance/near latent phoria (DLP/NLP), and accommodative convergence to accommodation ratio (AC/A) were compared between the two groups before wearing and after wearing the lenses for 6 months, and the effectiveness of myopia control between DIMS and HAL was further compared. Results After wearing the lenses (DIMS or HAL) for 6 months, the average increase in axial length was (0.09±0.14) mm, the average increase in spherical lens power was (-0.11±0.23) D, the average increase in astigmatism was (-0.07±0.16) DC, and the average increase in spherical equivalent was (-0.15±0.24) D, with statistically significant differences observed for all these changes (t=9.24, -7.27, -6.60, -9.03, respectively, P < 0.001). Compared with parameters before wearing the lenses, statistically significant differences were noted after wearing for 6 months in spherical lens power, cylindrical lens power, SE, BCC, PRA, DLP, average K, and AL (P≤0.001), except for NRA (t=-0.12, P>0.05), NLP (t=-0.28, P>0.05), and AC/A (t=0.33, P>0.05). The differences in parameters between the two groups after wearing the lenses for 6 months showed a statistically significant difference only in the AL difference (t=4.38, P≤0.001), with no statistically significant differences observed for other parameter differences (P>0.05). Conclusion Wearing defocus lenses has a positive effect on controlling myopia, delaying axial length elongation, and maintaining binocular visual function balance.
