Objective To summarize and analyze the clinical efficacy of negative pressure suction bell in the treatment of young children (≤6 years) with pectus excavatum. Methods The relevant clinical medical records of the children with pectus excavatum who received negative pressure suction bell treatment in the Outpatient Department of Children’s Hospital of Chongqing Medical University from May 2019 to January 2023 were collected. The age, sex, type, severity, depth of depression, duration of use and prognosis of children with pectus excavatum were retrospectively analyzed. Results A total of 100 pediatric patients were ultimately included in the study, comprising 74 males and 26 females. The age distribution was 57 patients aged 0-3 years and 43 patients aged 3-6 years. All patients were prescribed and used a negative pressure suction device for at least 3 months, after which they returned to our department's outpatient clinic for follow-up. The treatment demonstrated clinical effectiveness in 99 patients, yielding an efficacy rate of 99.00%. The excellent/good rate was 52.00%, and the complication rate was 8.00%. After treatment, the Haller index and the depth of sternal depression were reduced compared with those before treatment (P<0.001), and there was no statistical difference in the effective rate and excellent/good rate between different genders, different ages, different types of pectus excavatum, or different severity (P＞0.05). Conclusion Negative pressure suction bell is safe and effective in the treatment of young children (≤6 years) with pectus excavatum, and the correction effect has nothing to do with gender, type and severity.

Standardized clinical trial reporting is crucial for ensuring the scientific validity,reproducibility,and clinical translational value of reported results.The Consolidated Standards of Reporting Trials(CONSORT)statement,an internationally recognized guideline for randomized controlled trials(RCTs),has become an important reference standard for writing research papers in medicine since the 2010 version of CONSORT was published.With advancements in scientific research methodologies and the emergence of new forms of clinical trials,the CONSORT working group released an updated version in April 2025,published in journals such as The BMJ.Herein,we provide a systematic interpretation of the core revisions of CONSORT 2025,as well as a comparison with CONSORT 2010 to highlight the key differences.By providing practical,example-based recommendations,we aim to help domestic researchers apply the new guidelines efficiently,thereby improving the quality of clinical trial reports authored by domestic researchers.

A high-quality clinical trial protocol is the cornerstone for ensuring the scientific integrity and ethical compliance of a study.The Standard Protocol Items:Recommendations for Interventional Trials(SPIRIT)has become the international benchmark for developing clinical trial protocols since its release in 2013.To adapt to the developing trends of open science and patient-centered principles,the SPIRIT group completed a comprehensive update in 2025.While retaining its core structure,this updated guideline introduces a new open science module and incorporates several new elements,including patient and public involvement,trial monitoring,and data sharing,alongside substantial revisions of five pre-existing items.In this article,we critically examine the core revisions in SPIRIT 2025 and,through analysis of representative case studies,illustrate the practical application of the new reporting guideline in drafting trial protocols.Our goal is to to provide Chinese researchers with a valuable reference for understanding and implementing this new reporting guideline,thereby enhancing the quality and rigor of clinical trial protocols developed in the country.

Objective To construct an age prediction model for adolescents using radiomics from oral panoramic radiographs.Methods Panoramic radiographic images of 441 adolescent patients aged 11.00～13.99 years were imported into the open-source software 3D Slicer for segmentation of regions of interest(ROI).Python was used to extract all features from the ROIs of all patients.The patients were randomly divided into a training set and a test set at a ratio of 7∶3.Machine learning methods were applied to analyze the correlation between radiomics features and age characteristics to build the age prediction model.Results Out of 863 two-dimensional radiomics features,10 were selected.Three machine learning methods—support vector machine,random forest,and logistic regression—were used to train the model on the training set,and the best machine learning model was chosen.The performance of the machine learning models was evaluated using the Area Under Curve(AUC).In the test set,the AUCs for females were 0.795,0.830,and 0.795 for the three methods respectively,while for males,they were 0.830,0.864,and 0.846.Conclusion The radiomics model based on oral panoramic radiographs demonstrates good diagnostic efficacy and can be used for age prediction.

Objective:To establish the sensitive quality indicators for cardiovascular nursing based on the RAND Corporation University of California, Los Angeles (RAND-UCLA) expert consensus method, so as to lay the foundation for scientific and standardized quality management of cardiovascular nursing.Methods:Relevant literature was searched on China National Knowledge Infrastructure, WanFang Data, VIP, China Biomedical Literature Database, Cochrane Library, PubMed, EMbase and CINAHL. The search period was from database establishment to August 31, 2021. We used the Johns Hopkins evidence-based nursing practice model for evidence-based analysis and summary, and referred to documents on cardiovascular nursing quality indicators to form an indicator pool. From May 23 to July 12, 2022, 17 experts were selected to apply the RAND-UCLA expert consensus method to inquire about the indicators.Results:The effective response rates of the first and third rounds of the questionnaire were both 100.00% (17/17) , and the authority coefficients of the experts were 0.87 and 0.88, respectively. Among the 18 indicators in the third round of expert consultation, the consistency degree of importance and operability of all indicators was less than 1.00. Finally, 18 sensitive quality indicators for cardiovascular nursing were established.Conclusions:The consistency and coordination of experts in this study are good, and the nursing sensitive indicators formed have scientific characteristics, cardiovascular specialty characteristics, and good operability.

Objective:To investigate the predictive value of thrombus enhancement (TE) and thrombus permeability in cardioembolic thrombus with acute middle cerebral artery occlusion based on CT.Methods:The clinical and image data of 93 patients with acute middle cerebral artery occlusion who were admitted to the First Affiliated Hospital of Soochow University within 12 hours after onset from January 2020 to July 2022 were retrospectively analyzed. According to the TOAST criteria, the patients were divided into the cardioembolism (CE) group (43 cases) and the large artery atherosclerosis (LAA) group (50 cases). All patients received noncontrast CT and CT angiography, and then thrombus permeability [thrombus attenuation increase (TAI), void fraction (ε)] and TE were assessed. Independent sample t-test, Mann-Whitney U test and χ2 test were used in univariable analysis between two groups. Multivariable logistic regression analysis was used to explore the independent influencing factors for cardioembolic stroke and establish a logistic model. The receiver operating characteristic (ROC) curve and the area under the curve (AUC) were used to evaluate the predictive value of TAI, ε, TE and the logistic model in cardioembolic thrombus with acute middle cerebral artery occlusion. Results:There were statistically significant differences in sex, atrial fibrillation, hypertension, diabetes mellitus, smoking, baseline National Institutes of health stroke scale (NIHSS), TAI, ε and TE between the CE group and the LAA group ( P<0.05). Binary logistics regression analysis showed that TAI (OR=1.300, 95%CI 1.147-1.473, P<0.001), hypertension (OR=0.116, 95%CI 0.025-0.535, P=0.006) and baseline NIHSS (OR=1.165, 95%CI 1.040-1.304, P=0.008) were independent influencing factors for cardioembolic thrombus. The ROC curve indicated that the logistic model predicted cardioembolic thrombus with the highest AUC of 0.907 (95%CI 0.848-0.966). TE predicted cardioembolic thrombus with the highest sensitivity of 90.7%. Conclusion:TE and thrombus permeability have application value for predicting cardioembolic thrombus with acute middle cerebral artery occlusion based on CT.

Background::Sepsis is a serious disease caused by infection. Aminophylline has anti-asthma and anti-inflammatory effects. We aimed to explore the safety and effect of aminophylline in sepsis.Methods::We conducted a clinical randomized controlled trial involving 100 patients diagnosed with sepsis within 48 h after intensive care unit (ICU) admission in two sites. All patients were randomized in a 1:1 ratio to receive standard therapy with or without aminophylline. The primary clinical outcome was all-cause mortality at 28 days.Results::From September 27, 2018 to February 12, 2020, we screened 277 septic patients and eventually enrolled 100 patients, with 50 assigned to the aminophylline group and 50 to the usual-care group. At 28 days, 7 of 50 patients (14.0%) in the aminophylline group had died, compared with 16 of 50 (32.0%) in the usual-care group ( P = 0.032). Cox regression showed that the aminophylline group had a lower hazard of death (hazard ratio = 0.312, 95% confidence interval: 0.129-0.753). Compared with the usual-care group, patients in the aminophylline group had a longer survival time ( P = 0.039 by the log-rank test). The effects of aminophylline on vasopressor dose, oxygenation index, and sequential organ failure assessment score were time-dependent with treatment. There were no significant differences in total hospitalization days, ICU hospitalization days, and rates of serious adverse events (all P > 0.05). No adverse events were observed in the trial. Conclusions::Aminophylline as an adjunct therapy could significantly reduce the risk of death and prolong the survival time of patients with sepsis.Trial registration::ChiCTR.org.cn, ChiCTR1800019173.

This study is to improve the quality standard and supply the scientific basis for Anemarrhenae Rhizoma and its raw processed products. Steroidal saponin including timosaponin BⅡ, timosaponin AⅢ and flavonoids including neomangiferin and mangiferin were selected as the indicative components. Silica gel G thin layer chromatography(TLC) and polyamide TLC were used to detect the two types of compounds, respectively. The contents of timosaponin BⅡ and timosaponin AⅢ were determined by HPLC-ELSD and the content of neomangiferin, mangiferin and isomangiferin were determined by HPLC-UV. Moisture, total ash and acid insoluble ash were determined according to Chinese Pharmacopoeia(2015 edition). And 80% ethanol was selected as the solvent and the content determination of total extract were determined. The fingerprints of Anemarrhenae Rhizoma and its raw processed products were established by HPLC-UV and HPLC-ELSD. The results showed that the methods of TLC and HPLC have been successfully stablished. There are 2 and 3 peaks which have been identified by HPLC-ELSD and HPLC-UV, respectively. The HPLC fingerprint methods are specific and can be used to identify and quality control for Anemarrhenae Rhizoma and its raw processed products in the mass. Comparing to Chinese Pharmacopoeia(2015 edition), the TLC identification and content determination were revised and the total extract determination and HPLC fingerprints were added in the present study. Our results can be used as the scientific basis of quqlity control for Anemarrhenae Rhizoma and its raw processed products.
