Objective: To analyze the relationship between asthma and nocturia in women based on the National Health and Nutrition Examination Survey (NHANES) database from 2005 to 2018,so as to provide reference for the prevention and treatment of female nocturia. Methods: Female respondents aged ≥20 years with nocturia or asthma were selected from the 2005-2018 NHANES database.Those with both diabetes stroke and obstructive sleep apnea syndrome were excluded.A weighted analysis was conducted using a complex sampling design.The association between asthma and nocturia in women was evaluated with univariate analysis，propensity score matching (PSM)，and multivariate logistic regression models. Results: A total of 14 718 respondents were selected，of whom 1426 (9.7%) were diagnosed with asthma，and 4664 (31.7%) with nocturia.There is a significant correlation between asthma and nocturia (χ =39.846，P<0.01). Age，body mass index (BMI)，smoking and race were also associated with nocturia (P<0.01).Multivariate logistic regression analysis showed that，the age，BMI，smoking，race and asthma were correlated with the risk of nocturia，before PSM matching (P<0.05).To eliminate confounding bias，PSM was applied，and generalized linear mixed model analysis after matching showed that the risk of nocturia remained high in asthma patients (OR=1.540，95% CI：1.320-1.800，P<0.01). Conclusion: Asthma is associated with nocturia in women，indicating that it may be an important risk factor for female nocturia.

Objective To analyze the characteristics of real-world adverse drug events(ADEs)of trabectedin based on the FDA Adverse Event Reporting System(FAERS)database in order to provide references for clinical drug safety management.Methods A total of 1 349 trabectedin-related reports were extracted from the FAERS database from Q1 2007 to Q4 2024.Using the MedDRA coding classification system for system organ class(SOC)and preferred term(PT),signal detection was performed through 4 proportional imbalance methods,including reporting odds ratio(ROR)and proportional reporting ratio(PRR).Subgroup analyses by gender,age,and temporal trends were also conducted.Results Hematological and lymphatic system disorders and hepatobiliary system disorders were the primary SOCs involved.High-frequency PTs included neutropenia(123 cases)and anemia(117 cases).Eight potential ADEs that have not been listed in the drug product instruction were identified.The median onset time of ADEs was 21 d,showing an early failure pattern,with differences observed by gender(females more prone to hematological toxicity)and age(elderly more susceptible to febrile neutropenia).Conclusion Trabectedin requires close attention to hematological toxicity,hepatotoxicity,and newly identified multi-system potential risks.Clinically,monitoring should be strengthened based on time windows and population characteristics to optimize drug regimens.Countermeasure It is recommended to strengthen the full cycle monitoring of anti-tumor drugs,standardize the reporting of adverse reactions,and establish a multi-departmental collaborative research platform.

Objective To discuss the factors influencing the occurrence of frailty in patients with acute myocardial infarction(AMI)after receiving interventional treatment,and to construct a prediction model,to draw a nomogram,and to make the validation of the model.Methods Using convenient sampling method,a total of 462 patients with AMI,who were admitted to the Department of Cardiovascular Medicine of three Grade Ⅲ-A hospitals in Shandong Province of China from July 2023 to January 2024,were selected as the study subjects.Among them,324 AMI patients encountered from July 2023 to November 2023 were selected as modeling group,and logistic regression was used to construct a risk prediction model and draw a nomogram to visualize the model.The remaining 138 AMI patients encountered from December 2023 to January 2024 were used as the validation group.The receiver operating characteristic(ROC)curve and Hosmer-Lemeshow testing were adopted to verify the predictive effect of the model.Results Of 324 patients in the modeling group,170(52.47％)developed frailty.Univariate analysis showed that significant differences in age,education level,body mass index(BMI),Charlson comorbidity index,grip strength,walking speed,brain natriuretic peptide precursor level,physical exercise,multiple medication,and kinesophobia existed between the two groups(all P＜0.05).Multivariate logistic regression analysis revealed that age,BMI,Charlson comorbidity index,grip strength,walking speed,NT-ProBNP precursor level,physical exercise,multiple medication,and kinesophobia were the influencing factors of frailty in patients with AMI after receiving interventional treatment,with an OR value of 1.061,0.630,1.529,0.931,0.005,0.358,1.783,2.929,and 0.497 respectively.The above nine factors were used as independent variables to draw the nomogram,the area under ROC curve of the model was 0.851(95％CI:0.809-0.892),the optimal critical value was 0.562,the sensitivity was 84.1％,and the specificity was 72.1％.Hosmer-Lemeshow goodness of fit testing showed that the model had anx2=12.957 and P=0.113.Conclusion The frailty condition of AMI patients after receiving interventional treatment is at a low to medium levels.The frailty risk prediction model constructed in this study has good prediction effect,which can provide guidance for clinical nurses to timely identify high-risk patients and to promptly adopt interventional measures.

Objective To investigate the expression of CD4+T cell subtypes and related inflammatory factors in patients with neutrophil-predominant frequent acute exacerbation chronic obstructive pulmonary disease(NE-FE-COPD).Methods COPD patients who were treated in the hospital from March 2019 to March 2021 were selected as the research objects.According to different phenotypes,they were divided into the infrequent exacerbator COPD group(IECOPD group,n=11),the eosinophilic dominant frequent acute plus severe COPD group(Eos-FE-COPD group,n=13),and the neutrophil dominant frequent exacerbator COPD group(NE-FE-COPD group,n=15).Patients with normal lung function and smoking history＞10 packs/year were the control group(CTRL group,n=9).Bronchoalveolar lavage fluid(BALF)was collected from each group,and the expression of CD4+T cell subtypes and inflammatory factors were detected by flow cytometry.The correlation between BALF and lung function and the frequency of acute exacerbation was ana-lyzed.CD4+CD28nullT cells and CD4+CD28+T cells were co-cultured with human airway epithelial cells(hAECs)and divided into co-culture group and Control group.The damage of hAECs was observed by immu-nofluorescence staining,and the mRNA and protein expression levels of ZO-1 and occludin were detected by RT-qPCR and Western blot.Results The proportion of CD4+CD28nullT cells and IL-1β level in BALF in the NE-FE-COPD group were higher than those in the CTRL group,the IE-COPD group,and the Eos-FE-COPD group,and the difference was statistically significant(P＜0.05).The proportion of CD4+CD28nullT cells and IL-1βlevel were negatively correlated with lung function(P＜0.05),and positively correlated with acute ex-acerbation frequency(P＜0.05).Compared with the Control group,hAECs tight junctions were damaged in the co-culture group,and mRNA and protein expression levels of ZO-1 and occludin decreased,with statistical significance(P＜0.05).Conclusion CD4+CD28nullT cells and IL-1β may be involved in the occurrence and de-velopment of NE-FE-COPD.

Objective:To investigate the DMD genetic variants of the Chinese population with Duchenne (DMD) and Becker muscular dystrophies (BMD).Methods:A cross-sectional study was conducted on 2 690 unrelated patients with DMD and BMD aged 0-18 who visited the Genetic and Prenatal Diagnosis Center of the First Affiliated Hospital of Zhengzhou University from January 2005 to February 2022. The clinical data, such as gender, age, clinical manifestations, and address, were collected. Multiplex ligation-dependent probe amplification, next generation sequencing panel, Sanger sequencing, and PCR amplification were used to detect the variants of the DMD gene in the patients, whose clinical information and gene detection results were descriptively analyzed.Results:The 2 690 patients included 2 648 males and 42 females, with an age of 6.0 (4.0, 9.0) years. The serum creatine kinase increased in all patients. Pathogenic DMD gene variants were detected in the 2 618 patients, including 1 875 cases (71.6%) large deletions, 231 cases (8.8%) duplications, and 512 cases (19.6%) small variants. Among the deletion variants, the deletion of 3 exons was the most common, accounting for 15.4% (288/1 875); and hotspot deletion involved exons 45 to 50, accounting for 6.3% (119/1 875). Exon 2 was the most common type duplication region, accounting for 13.0% (30/231). Small variants were distributed in all 79 exons of the DMD gene, with no hotspots. In addition, the 46 small variants were previously unreported.Conclusion:Exon deletion is the most common type of DMD gene variant, followed by small variants and exon duplication.

Objective:To explore the practical effects of achieving transformative learning in students based on the "case-based+problem-oriented" teaching method for the course of "orthopedic rehabilitation".Methods:A "case-based+problem-oriented" method was introduced in clinical courses for students in the rehabilitation therapy program at Tianjin Medical University. The students in the class were randomly divided into the "case-based+problem-oriented" teaching group (56 students) and the traditional teaching group (57 students). This study compared students' exam scores for different types of theoretical questions at the end of the semester. A self-filled anonymous questionnaire survey was conducted to evaluate the effectiveness of transformative learning, including the understanding of rehabilitation theory, learning interest, doctor-patient communication ability, disease analysis and judgment ability, and rehabilitation practice ability. SPSS 20.0 was used for t test and χ2 text. Results:The "case-based+problem-oriented" teaching group achieved significantly higher scores in various types of questions and total scores compared with the traditional teaching group [(85.67±4.78) vs. (72.98±6.49), t=8.78, P=0.004)]. Students in the "case-based+problem-oriented" teaching group showed higher interest in transformative learning and a considerably increased awareness of knowledge acquisition and innovative transformation. Students in the "case-based+problem-oriented" teaching group demonstrated higher abilities in theoretical learning, communication, disease exploration, and analytical judgment in this major and course. Conclusions:The "case-based+problem-oriented" clinical transformative teaching method integrates the theoretical teaching, clinical thinking, and medical training, promotes the students' enthusiasm for learning, and improves their proactive learning of knowledge and ability to transform and innovate.

The declining fertility has emerged as a significant concern impacting national welfare, with obesity identified as a major contributing factor. In the hypothalamus, gonadotropin-releasing hormone(GnRH) neurons release GnRH, which regulates the secretion of estrogen and testosterone via the hypothalamic-pituitary-gonadal(HPG) axis, thereby influencing sexual development and fertility. The proper function of GnRH neurons is crucial for maintaining normal sexual development and fertility. Research indicates that obesity can impact GnRH neuron function through several pathways, such as disrupting pulsatile secretion core kisspeptin neurons, causing imbalance in energy sensing and metabolic factor secretion, and triggering hypothalamic inflammation. These pathways directly or indirectly influence GnRH neuron function in the hypothalamus, which ultimately affects sexual development and impairs fertility. Therefore, this review consolidates recent advancements in understanding the mechanisms by which obesity induces dysfunction in hypothalamic GnRH neurons, offering new perspectives for early clinical interventions aimed at enhancing fertility outcomes in obese individuals.

For wild natural medicine, unanticipated biodiversity as species or varieties with similar morphological characteristics and sympatric distribution may co-exist in a single batch of medical materials, which affects the efficacy and safety of clinical medication. DNA barcoding as an effective species identification tool is limited by its low sample throughput nature. In this study, combining DNA mini-barcode, DNA metabarcoding and species delimitation method, a novel biological sources consistency evaluation strategy was proposed, and high level of interspecific and intraspecific variations were observed and validated among 5376 Amynthas samples from 19 sampling points regarded as "Guang Dilong" and 25 batches of proprietary Chinese medicines. Besides Amynthas aspergillum as the authentic source, 8 other Molecular Operational Taxonomic Units (MOTUs) were elucidated. Significantly, even the subgroups within A. aspergillum revealed here differ significantly on chemical compositions and biological activity. Fortunately, this biodiversity could be controlled when the collection was limited to designated areas, as proved by 2796 "decoction pieces" samples. This batch biological identification method should be introduced as a novel concept regarding natural medicine quality control, and to offer guidelines for in-situ conservation and breeding bases construction of wild natural medicine.

Currently， evidence on the efficacy and risk of traditional Chinese medicine （TCM） injections is seriously insufficient， and it is difficult to evaluate TCM injections comprehensively， truly and objectively using available efficacy evaluation indicators. Therefore， establishing a clinical efficacy evaluation system that can effectively reflect TCM injections is imperative. Core outcome set （COS） has played an important role in screening TCM efficacy evaluation indicators， however， there are still certain problems， such as large differences in efficacy indicators， non-standardization， and lack of featured and specific TCM indicators. Mixed method research （MMR） has the advantages of looking at problems from both quantitative and qualitative perspectives. It is thereby proposed to use COS and MMR integrated model to establish a clinical efficacy evaluation indicator system that not only fully considers the cha-racteristics of TCM injections， but also highlights the efficacy and advantages of TCM injections from the perspective of TCM intervention. Simultaneously， an indicator screening method using MMR to optimize COS research model is formulated， which can provide ideas for the research on efficacy evaluation indicators of TCM injections.
