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.

Objective:To explore the classification of bilobar anterolateral thigh perforator flaps assisted by color Doppler ultrasonography and its impact on their donor sites.Methods:A retrospective analysis was conducted of the data of 67 patients with large soft tissue defects who had been repaired with anterolateral thigh perforator flaps at Department of Orthopaedics, The Hospital Affiliated to The Second Medical University of Shandong, Department of Orthopaedics, The 80th Group Army Hospital of the People's Liberation Army, and Department of Orthopaedics, Weifang Traditional Chinese Medicine Hospital. The patients were divided into 2 groups according to their flaps used: a unilobar group and a bilobar group. In the unilobar group, 36 cases [25 males and 11 females with an age of (40.3±8.3) years] were repaired with a unilobar anterolateral thigh perforator flap from March 2015 to April 2019. In the bilobar group, 31 cases [22 males and 9 females with an age of (38.9±7.4) years] were repaired with a bilobar anterolateral thigh perforator flap from May 2019 to August 2023. Color Doppler ultrasonography was used to classify the bilobar flaps into 4 types according to the different distributions of perforating vessels: common trunk type, separate trunks type, fascia dependent type, and composite mixed type. The number of perforating vessels and type of perforator flap found by preoperative color Doppler ultrasound were compared with the intraoperative findings in the bilobar group. One year after operation, recovery rate of donor muscle strength, rate of skin paresthesia, scar length at the donor site, the widest scar width and motor function were compared between the 2 groups.Results:The number of perforating vessels and type of perforator flap found by preoperative color Doppler ultrasound were consistent with the intraoperative findings ( P<0.05). There was no significant difference in the preoperative general data between the 2 groups, indicating comparability ( P>0.05). One year after operation in the bilobar group, the recovery rate of donor muscle strength was 96.8% (30/31), significantly higher than that in the unilobar group [77.8% (28/36)], the rate of skin paresthesia 6.5% (2/31), significantly lower than that in the unilobar group [27.8% (10/36)], the scar length at the donor site (22.18±5.02) cm, significantly longer than that in unilobar group [(17.35±3.11) cm], the widest scar width (7.26±1.58) mm, significantly narrower than that in the unilobar group [(43.72±9.81) mm], and the scores of Vancouver Scar Assessment Scale and Fugl-Meyer lower limb motor function scale were (1.95±0.57) points and (8.39±2.17) points, respectively, significantly lower than those in the unilobar group [(6.38±1.72) points and (14.02±3.54) points] ( P<0.05). Conclusions:Preoperative classification of bilobar anterolateral thigh perforator flaps assisted by color Doppler ultrasonography may provide guidance for flap harvesting and lobe layout of the flap. Compared to traditional unilobar flaps, bilobar ones may minimize tissue damage at a donor site.

It is recommended that nurses comprehensively consider the clinical situation when applying evidence, selectively apply the best evidence, extend breastfeeding time, and promote maternal and infant health.

In recent years, the medical insurance coverage of China has been increased significantly, and the medical insurance policies have been launched continuously, so the traditional manual audit method is unable to support medical institutions to effectively supervise the medical insurance fund. In view of this situation, a tertiary hospital in Beijing had successfully built an intelligent medical insurance audit system for drugs, diagnosis and treatment projects under key supervision, realized the prior audit and in-process control of the illegal use of medical insurance funds, through the establishment of intelligent audit rules, the design of audit trigger points and the interception level of illegal medical orders, and the establishment of a pre-operational preparation system and continuous improvement mechanism. In March 2021, the hospital officially launched the system. After the application of the system, the amount and quantity of outpatient medical insurance refusal from April to September 2021 were 10 587 yuan and 72 respectively, which decreased by 79.21% and 77.50% compared with the same period in 2020. This system effectively improved the quality and efficiency of medical insurance fund supervision.

Background: The benefits and risks of eradicating Helicobacter pylori (Hp) should be balanced in aged people. Aims: To investigate the efficacy, safety and antibiotic resistance status of Hp eradication treatment in the elderly. Methods: Four cohorts of subjects who received Hp eradication treatment in randomized controlled trials conducted in Chongqing Daping Hospital were reviewed; the demographic and clinical data were extracted and recorded. Propensity score matching was performed to select comparable elderly group (≥60 years old) and non-elderly group (<60 years old). The eradication rate, compliance, adverse events, antibiotic resistance, and the influencing factors of eradication were analyzed in these two groups. Results: A total of 994 subjects receiving Hp eradication treatment were enrolled initially, among them, 224 were categorized as elderly group and non-elderly group by propensity score matching, with 122 subjects in each group. The Hp eradication rates were higher than 90% in both elderly and non-elderly groups, and no significant differences were observed in compliance, drug-related adverse events, and antibiotic resistance rates between these two groups (all P>0.05). Furthermore, there were no significant differences in the Hp eradication rates in terms of gender, cigarette smoking, alcohol consumption, comorbidities (hypertension, diabetes, surgical history, and inflammation), compliance, etc. in the elderly group (all P> 0.05). But in retreated elderly subjects, the resistance rate of clarithromycin was higher than that in naïve elderly subjects (P<0.05). Smoking and poor compliance were identified as independent risk factors for Hp eradication by multivariate Logistic regression analysis. Conclusions: Hp eradication in the elderly demonstrates comparable efficacy and safety with non-elderly subjects. Clarithromycin-containing regimens are not recommended for empirical retreatment in aged people.

Objective:To explore the changes of neuron specific enolase (NSE) concentration in serum samples of patients with silicosis.Methods:In January 2020, 455 cases of silicosis diagnosed in Yantaishan Hospital from January 2018 to December 2019 were collected, and 60 healthy cases and 120 cases of lung cancer were selected as the healthy group and the lung cancer group. The serum levels of NSE were detected by chemical immunofluorescence assay and compared.Results:The serum NSE level of silicosis patients was [(22.88±7.86) ng/ml], higher than that of healthy group [(17.96±4.42) ng/ml] ( P<0.05) . Serum NSE levels in the first, second and third stage silicosis groups were higher than those in the healthy group ( P<0.05) , but there was no statistically significant difference between the silicosis groups at different periods ( P>0.05) . The serum NSE level of silicosis patients was lower than that of the small cell lung cancer group ( P<0.05) , but there was no statistically significant difference between silicosis group and non-small cell lung cancer group ( P>0.05) . The area under curve of silicosis NSE was 0.718 ( P<0.01) when the cut-off was 17.49 ng/ml, the sensitivity and specificity of NSE was 78% and 57% respectively. Conclusion:The serum NSE level of patients with silicosis is significantly increased, which can be used as an important reference index for the diagnosis and the differential diagnosis of silicosis.
