OBJECTIVE To investigate the current status of informatization tools applied to antimicrobial stewardship in county hospitals in China， and to provide a reference for promoting the informatization development of antimicrobial stewardship in county hospitals.METHODS From August to September 2025， an online questionnaire survey was conducted among 1 007 county hospitals across 31 provinces（autonomous regions， and municipalities） in China. The survey focused on the application of four types of informatization tools：the real-time monitoring system for antimicrobial use， the pre-prescription review system， the irrational use warning system， and the electronic prescription evaluation system（hereinafter referred to as the “monitoring system”“review system”“warning system”“evaluation system”，respectively）. Correlation analysis and binary Logistic regression analysis were employed to explore the influencing factors.RESULTS Of the county hospitals， 80.83% were equipped with at least one type of informatization tool for antimicrobial stewardship， while 19.17% had no relevant tool. Only 18.87% of the hospitals were equipped with all four types of tools. The monitoring system exhibited the highest equipped rate （70.80%）， whereas the warning system was equipped in only 33.96% of the hospitals. Four types of tools are evenly and adequately deployed in the eastern region， the central and western regions have far lower deployment rates of intervention tools including review system and warning system， accompanied by prominent intra-provincial gaps. The total number of the health technicians， hospital grade， and prescription review rate of outpatient antibacterial drug were significantly and positively correlated with the deployment rates of the four informatization tools （ P ＜0.05）. The results of the Logistic regression model fitting indicated that the model of the review system was rated “excellent” [area under the receiver operating characteristic curve （AUC）＝0.81]， and the model of the warning system was rated “further improvement” （AUC＝0.67）. The total number of health technicians was significantly positively correlated with the deployment rates of all four types of informatization tools （all P ＜0.05）.CONCLUSIONS The informatization of antimicrobial stewardship in county hospitals in China remains in the initial stage of transitioning from “passive statistics” to “active prevention and control”， with challenges such as structural imbalance and regional disparities. In the future， differentiated support strategies should be implemented， the allocation of resources should be optimized， to enhance the level of refined antimicrobial stewardship.

ObjectiveTo analyze the protective effect of different types of influenza vaccines (InfV) against influenza A among the individuals aged between 3‒17 years old, and to provide a scientific basis for the prevention and control of influenza in the future. MethodsA retrospective cohort study was conducted to collect data on the incidence and InfV vaccination of the individuals aged between 3‒17 years during the influenza epidemic season from 2022 to 2023. Vaccine effectiveness (VE) was calculated, and a log-binomial regression model was used to calculate the corrected VE. ResultsThe incidence rate of influenza in InfV vaccinated and un-vaccinated groups was 7.32% (1 937/ 26 446) and 9.65% (4 421/45 837), respectively. After adjusting for age and gender factors, the unadjusted VE (95%CI) was 54.57% (52.24%‒56.78%). The unadjusted VE (95%CI) was 53.66% (50.36%‒56.74%) for males and 55.60% (52.24%‒58.72%) for females, respectively. The unadjusted VE (95%CI) for the age group of 3‒ years, 6‒ years, 9‒ years, 12‒ years, and 15‒17 years were 64.08% (60.89%‒67.01%), 57.40% (53.71%‒60.80%), 57.77% (52.49%‒62.47%), 24.36% (9.49%‒36.79%), and 24.09% (-17.59%‒51.00%), respectively. The unadjusted VE (95%CI) for quadrivalent split-virion inactivated influenza vaccine, trivalent split-virion inactivated influenza vaccine, trivalent subunit influenza vaccine, and trivalent live attenuated influenza vaccine were 53.84% (51.32%‒56.24%), 62.17% (56.28%‒67.26%), 79.83% (69.94%‒86.46%), and 31.59% (19.07%‒42.18%), respectively. ConclusionThe InfV used during the 2022‒2023 influenza season had a good protective effect against influenza A among the individuals aged between 3‒17 years old, especially in those aged between 3‒11 years old.

BACKGROUND: Lung cancer is the leading malignancy in China in terms of both incidence and mortality. With increased health awareness and the widespread use of low-dose computed tomography (CT), early diagnosis rates have been steadily improving. Surgical intervention remains the primary treatment option for early-stage lung cancer, and video-assisted thoracoscopic surgery (VATS) has become a common approach due to its minimal invasiveness and rapid recovery. However, post-discharge recovery remains incomplete, underscoring the importance of postoperative care. Traditional follow-up methods, lack standardization, consume significant medical resources, and increase the burden of the patients. Artificial intelligence (AI)-driven disease management platforms offer a novel solution to optimize postoperative follow-up. This study followed 463 lung cancer surgery patients using an AI-based platform, aiming to identify common postoperative issues, propose solutions, improve quality of life, reduce recurrence-related costs, and promote AI integration in healthcare. METHODS: Using the AI disease management platform, this study integrated educational videos, collaboration between healthcare teams and AI assistants, daily health logs, health assessment forms, and personalized interventions to monitor postoperative recovery. The postoperative rehabilitation status of the patients was assessed by the Leicester Cough Questionnaire (LCQ-MC). Two independent t-test and one-way ANOVA were used to analyze the causes of postoperative cough in lung cancer. RESULTS: Most issues occurred within 7 d post-discharge, significantly declined on 14 d post-discharge. Factors such as gender, smoking history, and surgical approaches were found to influence cough recovery. The incidence of cough on 7 d post-discharge in females was higher than that in males (P<0.01), while the incidence of cough on 14 d post-discharge in elderly patients was lower than that in young patients (P=0.03). The AI-based platform effectively addressed cough, pain, and sleep disturbances through phased interventions. CONCLUSIONS The AI-based platform significantly enhanced postoperative management efficiency and the self-care capabilities of the patients, particularly in phased cough management. Future integration with wearable devices could enable more precise and personalized postoperative care, further advancing the application of AI technology across multidisciplinary healthcare domains.

Objective:To explore the factors influencing ethical sensitivity of oncology nurses.Methods:Using purposive sampling, 15 oncology nurses from 13 tertiary general hospitals in Foshan, Guangdong Province were selected as research participants from July to September 2023. In-depth semi-structured interviews were conducted, and Colaizzi's seven-step content analysis method was applied to organize and analyze the collected data.Results:A total of 4 themes were summarized: insufficient clinical experience and knowledge reserve; lack of ethical education and management system processes; high-pressure working environment and communication barriers; and the constraints of the cultural concept of "valuing life over death".Conclusions:Oncology nurses have insufficient ethical sensitivity. Nursing managers should establish a systematic ethical education system, improve ethical management systems, optimize the clinical working environment, and integrate cultural sensitivity education to jointly enhance nurses' communication skills. Attention should also be paid to the inheritance of clinical experience from senior nurses, so as to improve the ethical sensitivity of oncology nurses in a multidimensional way.

To investigate the infection status of two arboviruses,akabane orthobunyavirus(AKAV)and bluetongue virus(BTV),in cattle herds of Guizhou Province,we employed the indirect ELISA method to detect AKAV and BTV antibody levels in the present experiment.A total of 1504 bovine serum samples from 37 large-scale farms and 88 free-range households from 26 districts or coun-ties of 7 cities(prefectures)of Guizhou Province were collected to detect AKAV antibody levels.Additionally,1 241 serum samples from 30 large-scale farms and 15 free-range households in 19 districts or counties of 3 cities(prefectures)were tested for BTV antibody levels.Moreover,two influencing factors,breeding mode and sampling season,were statistically analyzed for their effects.The results showed that the overall positive rate of AKAV antibodies was 11.64％(175/1 504),with individual positive rates of 13.20％(123/934)and 9.12％(52/570)in large-scale farms and free-range households,respectively.No significant differences were observed between the two groups.However,the farm positive rate(64.86％,24/37)in large-scale farms was significantly higher than that(26.14％,23/88)in free-range households.Seasonal statistics showed that the positive rate was highest during the summer season at 60.00％(12/20).The total positive rate of BTV antibodies was 25.42％(222/1 241).The farm positive rate and individual positive rate in free-range households were 66.67％(10/15)and 41.91％(57/136),respectively.For large-scale farms,these rates were 60.00％(18/30)and 14.93％(165/1 105),respectively.The individual pos-itive rate in free-range households was significantly higher than that in large-scale farms.Seasonal statistics showed that the positive rates in summer and autumn seasons were 50.00％(5/10)and 72.41％(21/29),respectively,both of which were significantly higher than those in winter and spring seasons.All these findings indicated that both AKAV and BTV were present to a certain ex-tent in Guizhou Province,with seasonality.Furthermore,differences were observed between the different breeding modes.Our results could provide a data reference for the formulation of preven-tion and control measures for the two insect-borne diseases.

Objective To establish a high-throughput method that can simultaneously, quickly, and accurately detect main malaria-transmitting Anopheles species and their resistance genes in China, providing a high-throughput monitoring tool for monitoring the main malaria vectors in China after malaria elimination. Methods In different sampling locations, including Tengchong City, Yunnan Province; Wenchang City, Hainan Province; and Donggang City, Liaoning Province, adult specimens of mosquitoes, including Anopheles sinensis, Anopheles minimus, Anopheles dirus, and Anopheles anthropophagus, were collected. Polymerase chain reaction (PCR) technology and Sanger sequencing were employed to detect the ITS2, kdr (L1014), rdl (A296), and ace-1 (G119) genes in individual mosquitoes. For the analysis of mixed samples, an optimized multiplex PCR reaction system, custom-designed dual barcode primers, and next-generation sequencing (NGS) technology were utilized to detect the aforementioned genes. The consistency was assessed using Kappa consistency tests and Chi-square tests for multiple rates. Sensitivity, specificity, and the Youden index were calculated using a four-grid table calculation method. The costs associated with each step of the normal operational process for each method were statistically summarized, and the optimal quantity of mixed samples for detection was determined by a comprehensive approach. Results Conventional PCR amplification of gDNA from 300 mosquitoes resulted in 144 individuals of Anopheles sinensis, 53 individuals of Anopheles dirus, 62 individuals of Anopheles anthropophagus, and 41 individuals of Anopheles minimus, as identified by Sanger sequencing. The mutation frequencies of resistance genes kdr (L1014), rdl (A296), and ace-1 (G119) were found in 73, 27, and 41 specimens, respectively. Using a newly established multiplex PCR reaction system based on custom dual barcode and NGS sequencing technology, samples corresponding to Sanger sequencing were detected under different sample sizes. The two methods showed high consistency in the results (all Kappa>0.900). Multiple comparison tests showed significant differences in the consistencies of the two methods across different sample sizes N (40, 80, 160), N (120, 200, 240, 280), and N (300) (χ2=26.547, P<0.001). The new method demonstrated high sensitivity and specificity across various sample sizes, with the Youden index ranging from highest to lowest as follows: 1 (40, 80, 160)>0.994 (120)>0.990 (280)>0.988 (200)>0.987 (240)>0.985 (300). With an increase in sample size from 40 to 300, the cost per sequencing site for the new method decreased from 20.0 yuan to 8.3 yuan, while the cost per sequencing site for the conventional method decreased from 16.7 yuan to 15.4 yuan. The optimal mixed sample size for the new method was determined to be 280. Conclusion The newly developed multiplex PCR and barcode NGS detection method enables simultaneous screening of four major malaria vector mosquito species and the presence of mutations in the ace-1, kdr, and rdl resistance genes, exhibiting excellent stability, high sensitivity, and specificity. It allows for the efficient analysis of large sample sizes in a single run, offering a cost-effective alternative compared to other types of detection methods.
