Objective:Taking Inflammatory Bowel Disease(IBD)patients as an example,to explore the impact of disparities in regional outpatient security policies on medication reimbursement benefits for patients,and to provide insights for promoting the reform and development of equal outpatient security policy.Methods:39 cities from 9 provinces in China were selected as research samples to analyze the types,coverage,and benefits of their outpatient security policies.Indicators such as the individual out-of-pocket ratio,deductible,and specified reimbursement rate were used to simulate the actual reimbursement ratio for IBD patients using negotiated drugs.Results:Under the general outpatient coordination policy,the average actual reimbursement rate for medications in IBD patients was 26.36%for residents and 36.47%for employees.Under the outpatient chronic and special disease policy,the average actual reimbursement rate was 42.49%for residents and 50.94%for employees,while patients receiving drug treatment under the outpatient special drug policy have an average actual reimbursement rate of 51.62%(for residents)and 64.92%(for employees).Conclusion:Under China's outpatient security policies,there are significant disparities in reimbursement benefits for IBD patients across different regions.Therefore,it is recommended to strengthen the coordination of outpatient security policies across regions,optimize policy design,and provide patients with more equitable and accessible medical coverage.

Objective:To identify the risk factors and their predictive value for complications in neonates with early-onset group B streptococcus (GBS) sepsis. Methods:This case-control study retrospectively analyzed 96 neonates with early-onset GBS sepsis (age of onset<7 days) admitted to Children's Hospital of Soochow University between January 1, 2007, and December 31, 2022. Patients were categorized into complication ( n=36) and non-complication ( n=60) groups. Receiver operating characteristic (ROC) curves determined optimal cutoff values of Pediatric Sequential Organ Failure Assessment (pSOFA) and Pediatric Logistic Organ Dysfunction Score 2 (PELOD-2) for predicting complications in the neonates with early-onset GBS sepsis. Independent t-tests, Mann-Whitney U tests, Chi-square tests and Fishe exact tests were used for group comparison of general information, clinical manifestations, auxiliary examinations, and treatment during hospitalization. Multivariate logistic regression identified independent risk factors, and ROC curves evaluated their predictive performance for complications in the neonates with early-onset GBS sepsis. Results:ROC analysis identified pSOFA>4.5 scores and PELOD-2>5.5 scores as optimal thresholds for complication prediction in neonates with early-onset GBS sepsis. (1) The complication group exhibited higher rates of preterm birth [30.6% (11/36) vs. 5.0% (3/60), χ2=11.80], maternal clinical chorioamnionitis [25.0% (9/36) vs. 5.0% (3/60), χ2=6.50], prolonged rupture of membranes≥18 h [22.2% (8/36) vs. 5.0% (3/60), χ2=4.99], invasive mechanical ventilation [36.1% (13/36) vs. 13.3% (8/60), χ2=6.83], fever [22.2% (8/36) vs. 3.3% (2/60), χ2=6.70], lethargy [77.8% (28/36) vs. 51.7% (31/60), χ2=6.48], mottled skin as the initial clinical manifestation [38.9% (14/36) vs. 20.0% (12/60), χ2=4.07], leukopenia [44.4% (16/36) vs. 18.3% (11/60), χ2=7.59], hypoalbuminemia [27.8% (10/36) vs. 3.3% (2/60), χ2=10.16], pSOFA>4.5 [83.3% (30/36) vs. 35.0% (21/60), χ2=21.11], PELOD-2>5.5 [50.0% (18/36) vs. 5.0% (3/60), χ2=26.66], and dual-positive blood and cerebrospinal fluid cultures [25.0% (9/36) vs. 0.0% (0/60), Fisher exact test] compared to the non-complication group (all P<0.05). Serum creatinine [(88.4±17.7) vs. (61.9±17.7) μmol/L, t=－6.02], urea nitrogen [(3.7±0.4) vs. (3.4±0.6) mmol/L, t=－3.18], and lactate [(7.5±3.4) vs. (5.8±2.2) mmol/L, t=－2.80] were elevated, while fibrinogen [(2.2±1.1) vs. (2.7±1.0) g/L, t=2.03], pH (7.3±0.2 vs. 7.4±0.1, t=2.04), and albumin [(28.2±3.9) vs. (31.9±4.2) g/L, t=4.32] were reduced in the complication group (all P<0.05). (2) Multivariate analysis identified preterm birth ( OR=6.642, 95% CI: 1.210-36.473), along with hypoalbuminemia ( OR=8.202, 95% CI: 1.184-56.811), pSOFA>4.5 scores ( OR=5.284, 95% CI: 1.573-17.749), and PELOD-2>5.5 scores ( OR=8.464, 95% CI: 1.922-37.279) assessed on admission day 1 as independent risk factors (all P<0.05). The area under the curve for predicting complications in early-onset GBS sepsis neonates was 0.628 (95% CI: 0.523-0.724) for preterm birth, and 0.622 (95% CI: 0.517-0.719), 0.742 (95% CI: 0.642-0.826), and 0.725 (95% CI: 0.624-0.811) for hypoalbuminemia, pSOFA>4.5 scores, and PELOD-2>5.5 scores assessed on admission day 1, respectively. The combined predictive model integrating all four risk factors achieved the highest area under the curve of 0.868 (95% CI: 0.784-0.929). Conclusion:Preterm birth as well as hypoalbuminemia, pSOFA>4.5 scores, and PELOD-2>5.5 scores at admission are critical risk factors for complications in early-onset GBS sepsis, warranting heightened clinical vigilance.

With the rapid development of radiological diagnosis and treatment technology, the construction of radiation diagnosis and treatment machine room and radiation safety management have become an important part of the daily management of hospitals. Due to the large number of laws and regulations involved, some hospitals still have problems such as imperfect construction of management systems, and insufficient professional competence of personnel, which leads to a lack of experience in the construction of radiation diagnosis and treatment room and radiation safety management in hospitals. This paper analyzed the practical experience of construction of radiological diagnosis and treatment machine room and radiation safety management. This paper analyzed the experience in constructing protective facilities for radiation diagnosis and treatment rooms in a medical institution, and provides the basis and reference for relevant units in room construction and radiation safety management.

Objective:To study the application value of vacuum drainage technology in radioactive wastewater discharge system of hospitals, and provide theoretical basis and reference for relevant institutes to design or renovate their radioactive wastewater discharge systems.Methods:Based on the composition of vacuum drainage system and gravity drainage system, the differences in water consumption and other factors of different systems were theoretically evaluated. To take the radioactive wastewater discharge system in a hospital as a research example, the storable periods of the fixed decay pool were calculated by using the two different drainage techniques.Results:Compared with the traditional gravity drainage technology, the vacuum drainage technology could save a lot of water and significantly reduce wastewater discharge. The water consumption was 16% of that of ordinary toilets with gravity drainage. By using the vacuum drainage technology to reform the radioactive wastewater discharge system of the hospital under the same amount of diagnosis and treatment workload, the storable period of radioactive wastewater could be extended by nearly three times, from 92.5 d before the renovation to 297 d after the renovation, without increasing the capacity of the decay pool. After the transformation, the total activity and volumetric activity concentration of 131I when discharging wastewater from each decay tank could be reduced to 4 096 Bq and 0.17 Bq/L, respectively, and the volumetric activity concentration was much lower than the national emission requirements. Conclusions:Vacuum drainage can significantly reduce wastewater production, and is worth promoting and applying in nuclear medicine departments.

Objective To evaluate the effectiveness and safety of inferior oblique transposition combined with medial and lateral rectus surgery in the treatment of inferior oblique hyperfunction combined with V-type strabismus.Methods Thirty-nine patients with inferior oblique hyperfunction combined with V-type strabismus admitted to Jiaxing Hospital of Traditional Chinese Medicine Affiliated to Zhejiang Chinese Medical University from November 2020 to September 2021 were selected as study objects,and were divided into combined operation group(n=28)and multiple operation group(n=11)according to different surgical programs.The visual acuity,eye position,cure rate of V sign,correction rate of inferior oblique hyperfunction,oculocardiac reflex,oculogastric reflex and complications were compared between two groups.Results One month after surgery,patients of two groups recovered the first eye position,and there were no statistical significances in the number of V sign cured and the number of inferior oblique hyperfunction corrected(P>0.05).Visual acuity returned to preoperative level in both groups.There were no significant differences in oculocardiac reflex and oculogastric reflex between two groups(P>0.05).There were no inflammatory reaction,massive subconjunctival hemorrhage,subcutaneous hematoma of eyelid,retrobulbar hemorrhage and other complications in two groups.Conclusion The effect of inferior oblique transposition combined with medial and lateral rectus surgery in the treatment of inferior oblique hyperfunction combined with V-type strabismus is not inferior to that of conventional divided operation,but it can reduce the number of operations and avoid the pain caused by the second operation,which is worthy of clinical application.

Dry eye disease(DED)refers to a condition characterized by reduced stability of the tear film or an imbalance in the microenvironment of the ocular surface, resulting from abnormalities in quality, quantity and kinetics of tear. This condition leads to various ocular discomforts and even visual impairment. The pathogenesis of DED is multifactorial and current treatment mainly focuses on symptom relief and preservation of visual function. Acupuncture has shown effectiveness in treating dry eye, although its underlying mechanism remains incompletely understood. Proteomics technology offers a comprehensive and systematic approach to studying the functions, structures and interactions of proteins. Its application in DED research can provide valuable insights into the dynamic changes in protein levels associated with different etiology or the course of DED and facilitate the identification of potential biomarkers. Furthermore, proteomics can systematically explore the regulatory mechanisms underlying acupuncture treatment for DED, providing a theoretical basis for acupuncture treatment research and contributing to the understanding of its effects at a fundamental level. This paper aims to explore the potential application of proteomics in both clinical and basic research on DED. Ultimately, it strives to offer scientific and effective strategies for the diagnosis and treatment of DED and advance our knowledge of the mechanisms underlying acupuncture therapy.
