Objective To evaluate the application value of artificial intelligence (AI) in the quality control of mammographic images and explore its feasibility for improving image quality. Methods A retrospective analysis was conducted on 500 mammographic images from 125 female patients. These images were acquired in December 2024 at the Department of Radiology, Obstetrics and Gynecology Hospital of Tongji University by two junior technologists with qualification certificate for junior radiologic technologists and ≤ 2 months of independent operation. The reference standard was the evaluation by a panel of senior experts comprising one associate chief radiologist and two intermediate radiologic technologists with over 10 years of experience in mammography. The evaluation was based on nine criteria within an AI quality control system. The correlation and consistency (Kappa test) of the assessment outcomes were compared among the junior technologist group, the AI quality control group, and the panel group. Additionally, the differences in the proportions of high-, medium-, and low-quality images rated by the three groups were analyzed. After one month of AI assistance, 200 images from 50 additional patients acquired by the same two junior technologists in January 2025 were collected. The area under the receiver operating characteristic curve and 95% confidence interval (95%CI) were calculated for the assessment performance of the junior technologist group before and after AI assistance. Differences were compared using the DeLong test. Changes in the disqualification rates for the nine criteria were analyzed. Results In consistency analysis, the AI quality control group showed high consistency with the panel group across multiple key criteria, with Kappa values ranging from 0.41 to 1.00. In contrast, the consistency between the junior technologist group and the panel group was generally low, with Kappa values ranging from 0.13 to 0.49. In comparison of image quality classification, no significant differences were observed in image quality classification between the AI group and the panel group (P>0.05). However, the proportion of images rated as high quality by the junior technologist group was significantly higher, while the proportions rated as medium and low quality were significantly lower, compared to those rated by the panel group (P<0.05). After AI assistance, the area under the receiver operating characteristic curve for the assessment performance of junior technologist group increased significantly from 0.56 (95%CI: 0.51-0.61) to 0.91 (95%CI: 0.87-0.94) (P<0.001). The disqualification rates for skin folds, incomplete inclusion of the pectoralis major muscle, and nipple not in profile decreased significantly. Conclusion AI demonstrates assessment capability comparable to the panel group in mammographic quality control. AI effectively enhances the quality of images acquired by junior technologists through real-time, objective feedback.

AIM: To evaluate clinical efficacy of recombinant human epidermal growth factor(rhEGF)combined with adjuvant amniotic membrane transplantation in corneal alkaline burns. METHODS:In the prospective, randomized controlled study, patients with corneal alkaline burns treated in the hospital were enrolled between November 2022 and November 2024. After emergency treatment, patients were divided into combined treatment group and routine treatment group by random number table method. The routine treatment group was given basic treatment(rhEGF), while combined treatment group additionally underwent adjuvant amniotic membrane transplantation. The clinical efficacy, healing time of corneal epithelium, best corrected visual acuity, VAS scores, corneal neovascularization area, break-up time, score of corneal opacity, and levels of inflammatory factors(IL-6, hs-CRP, TNF-α)in the two groups were observed and compared. RESULTS:There were 110 patients(110 eyes)in this study, including 55 cases(55 eyes)in each group. The combination group had a mean age of 46.82±10.38 y, including 26 males and 29 females. The routine treatment group had a mean age of 45.13±11.57 y, with 31 males and 24 females. The total response rate of combined treatment group [94.5%(52/55)] was significantly higher than that of routine treatment group [81.8%(45/55), P<0.05]. The healing time of corneal epithelium in combined treatment group was significantly shorter than that in routine treatment group(P<0.001), and VAS score for pain severity after treatment was significantly lower than that in routine treatment group(P<0.001). The corneal neovascularization area in combined treatment group was significantly smaller than that in routine treatment group(P<0.001), break-up time was significantly longer than that in routine treatment group(P<0.001),and score of corneal opacity was significantly lower than that in routine treatment group(P<0.001). After treatment, levels of inflammatory factors in combined treatment group were significantly lower than those in routine treatment group(all P<0.05). CONCLUSION:Adjuvant amniotic membrane transplantation combined with rhEGF presents prominent clinical advantages in the treatment of alkaline corneal burns. It can enhance therapeutic efficacy, accelerate wound healing, relieve pain, reduce corneal neovascularization, prolong tear film break-up time, alleviate corneal opacification, and reduce the levels of inflammatory factors.

Objective To provide a reference for the establishment, development and application of the adverse drug reaction (ADR) automated monitoring system, through verifying and quantifying the research hotspots and advantages of the system by CiteSpace software and systematic review. Methods Literature on ADR automated monitoring up to December 2023 were retrieved and screened from CNKI and web of science databases. CiteSpace 6.4.R1 software was used to conduct co-occurrence, clustering and emergence analysis, and to visualize and comparatively analyze the research hotspots, rules and distribution in the field of automated monitoring of ADR at home and abroad. In compliance with the preferred reporting items for systematic reviews and Meta-analyses (PRISMA), literature covering publications in English and Chinese including detection rates of ADR collected using Incident Reporting Systems (IRSs) and/or automated monitoring systems were retrieved and screened. The advantages and disadvantages of automated monitoring systems were analyzed by comparing the differences between these two systems in terms of the number of ADR reports and the types of positive signals. Results A total of 56 articles in English and 80 articles in Chinese were indexed by CiteSpace. The research hotspots in recent years included data mining, deep learning, text classification techniques, machine learning and so on. A total of seven studies compiled with the inclusion criteria for the systematic evaluation, all of which were completed between 1991 and 2021 in hospitals in four countries. 150 526 medical records were reviewed from 15 institutions. A total of 194 ADR reports were collected by IRSs. A total of 2 090 ADR reports were collected by the automated monitoring system over the same period, indicating a 977% increase in the number of ADR reports (P=0.0156) compared with the IRSs. Conclusion The ADR automatic monitoring system had significantly improved the level of drug risk identification and reduced costs, but it was necessary to optimize the algorithm, expand the data source and carry out standardization construction to overcome the current limitations.

Objective:To investigate the application value of gastric suspension method in supra-pancreatic lymph node dissection of laparoscopic radical gastrectomy of gastric cancer.Method:The retrospective cohort study was conducted. The clinicopathological data of 84 patients who under-went laparoscopic radical gastrectomy of gastric cancer at Zhejiang Cancer Hospital from August 2023 to July 2024 were collected. There were 61 males and 23 females, aged (64±11)years. Of the 84 patients, 42 patients undergoing supra-pancreatic lymph node dissection during laparoscopic radical gastrectomy of gastric cancer with traditional method for surgical field exposure were divided into the control group, and 42 patients undergoing supra-pancreatic lymph node dissection during laparoscopic radical gastrectomy of gastric cancer with gastric suspension method for surgical field exposure were divided into the suspension group. Observation indicators: (1) surgical conditions; (2) postoperative conditions. Comparison of measurement data with normal distribution between groups was conducted using the independent sample t test. Comparison of measurement data with skewed distribution between groups was conducted using the Mann-Whitney U test. Comparison of count data between groups was conducted using the chi-square test. Results:(1) Surgical condi-tions. The time for supra-pancreatic lymph node dissection of the control group was (78±14)minutes. Number of grasping operations was 116±34, number of bleeding sites caused by grasping operations was 7.8±2.7, and operation time was (3.9±0.8)hours. The above indicators of the suspension group were (59±12)minutes, 68±19, 2.1±1.5, and (3.3±0.7)hours, respectively. There were significant diffe-rences in the above indicators between the two groups ( t=5.42, 8.10, 8.31, 3.14, P<0.05). (2) Post-operative conditions. The tumor diameter was 2.5(2.0,3.5)cm for patients of the control group, versus 3.0(2.4, 4.4)cm for patients of the suspension group, showing a significant difference between the two groups ( Z=-1.98, P<0.05). Conclusion:Compared with the traditional non-suspension method, the gastric suspension method in laparoscopic radical gastrectomy of gastric cancer for supra-pancreatic lymph node dissection is associated with shorter operation time and less trauma.

Objective:To establish a dose-response curve of dicentric chromosomes and centromeric rings (dic+ r) in γ-ray irradiation-induced chromosomal aberrations in human peripheral blood lymphocytes through automated analysis.Methods:Peripheral blood samples from three healthy donors were irradiated in vitro at doses of 0, 0.5, 0.75, 1, 1.5, 2, 3, 4, and 5 Gy and a dose rate of 0.80 Gy/min using a 137Cs γ-ray source. Post-irradiation, lymphocytes were cultured based on standard protocols, harvested using an automatic cell harvester, and prepared on slides using an automatic slide preparation system. dic+ r were analyzed fully automatically using the DCScore software, and a dose-response curve of dic+ r was established through fitting and then validated using the CABAS software. Results:The dose-response curve followed a linear-quadratic model, i. e., y = 0.093 65+ 0.030 21 D+ 0.025 31 D2 ( R2 = 0.999 2), where y was the quantity of dic+ r and D was the absorbed dose of γ-ray irradiation (Gy). Doses to samples for blind validation were estimated using this curve, yielding deviations of less than 24% from the actual irradiation doses. Conclusions:The fully automated analysis of dic+ r in 137Cs γ-ray irradiation-induced chromosomal aberrations, followed by the construction of the dose-response curve, holds significant potential for rapid, high-throughput biodosimetry in large-scale nuclear emergencies.
