Maternal health during pregnancy has a direct impact on the risk and severity of neurodevelopmental disorders (NDDs) in the offspring, especially in the case of drug exposure. However, little progress has been made to assess the risk of drug exposure during pregnancy due to ethical constraints and drug use factors. We collected and manually curated sub-pathways and pathways (sub-/pathways) and drug information to propose an analytical framework for predicting drug candidates. This framework linked sub-/pathway activity and drug response scores derived from gene transcription data and was applied to human fetal brain development and six NDDs. Further, specific and pleiotropic sub-/pathways/drugs were identified using entropy, and sex bias was analyzed in conjunction with logistic regression and random forest models. We identified 19 disorder-associated and 256 regionally pleiotropic and specific candidate drugs that targeted risk sub-/pathways in NDDs, showing temporal or spatial changes across fetal development. Moreover, 5443 differential drug-sub-/pathways exhibited sex-biased differences after filling in the gender labels. A user-friendly NDDP visualization website ( https://ndd-lab.shinyapps.io/NDDP ) was developed to allow researchers and clinicians to access and retrieve data easily. Our framework overcame data gaps and identified numerous pleiotropic and specific candidates across six disorders and fetal developmental trajectories. This could significantly contribute to drug discovery during pregnancy and can be applied to a wide range of traits.

Iron is an essential trace element in the human body, crucial in maintaining normal physiological functions. Recent studies have identified iron ions as a significant factor in initiating the ferroptosis process, a novel mode of programmed cell death characterized by iron overload and lipid peroxide accumulation. The iron metabolism pathway is one of the primary mechanisms regulating ferroptosis, as it maintains iron homeostasis within the cell. Numerous studies have demonstrated that abnormalities in iron metabolism can trigger the Fenton reaction, exacerbating oxidative stress, and leading to cell membrane rupture, cellular dysfunction, and damage to tissue structures. Therefore, regulation of iron metabolism represents a key strategy for ameliorating ferroptosis and offers new insights for treating diseases associated with iron metabolism imbalances. This review first summarizes the mechanisms that regulate iron metabolic pathways in ferroptosis and discusses the connections between the pathogenesis of various diseases and iron metabolism. Next, we introduce natural and synthetic small molecule compounds, hormones, proteins, and new nanomaterials that can affect iron metabolism. Finally, we provide an overview of the challenges faced by iron regulators in clinical translation and a summary and outlook on iron metabolism in ferroptosis, aiming to pave the way for future exploration and optimization of iron metabolism regulation strategies.

Objective To analyze the characteristics of brain functional networks in patients with post-stroke aphasia(PSA)during a Chinese word-picture matching task.Methods A total of 18 PSA patients in Dongzhimen Hospital from January,2018 to December,2021 were enrolled as PSA group,and nine healthy controls matched for sex,age and education were included as the control group.The Chinese Rehabilitation Research Center Aphasia Examination(CRRCAE)and task-state electroencephalogram(EEG)data based on a Chinese word-picture matching paradigm were collected.Source-space reconstruction was applied to EEG signals to construct functional connectivity matrices.Graph-theoretical analysis was used to com-pute global network properties,and network-based statistics were used to identify subnetwork differences be-tween groups.Correlations between global network properties and CRRCAE subscales were further analyzed.Results The global properties of each frequency band were higher in the control group(unmatched)than in PSA group and the control group(matched)(P<0.01).Subnetworks connections enhanced in the alpha band in the frontal,temporal,parietal,occipital lobes and limbic system(23 nodes,31 edges,P<0.05),and weakened connections in the frontal,temporal,limbic system and basal ganglia(20 nodes,26 edges,P<0.01)in PSA group;in the beta band,subnetwork connections enhanced in the frontal,temporal lobes,basal ganglia and limbic system(15 nodes,23 edges,P<0.01);in the theta band,subnetwork connections weakened in the left frontal and temporal lobes(10 nodes,11 edges,P<0.05),and enhanced in the right frontal and temporal lobes(7 nodes,7 edges,P<0.05).Under the matched condition,the global properties of the alpha and beta bands in PSA group were positive-ly correlated with reading(r=0.511 to 0.650,all P<0.05),and the local efficiency and average clustering coeffi-cient of the theta band were negatively correlated with repetition(r=-0.500 to-0.505,all P<0.05);under the unmatched condition,the local efficiency and average clustering coefficient of the alpha and beta bands in PSA group were positively correlated with reading(r=0.522 to 0.642,all P<0.05),and the global efficiency and lo-cal efficiency of the alpha band were positively correlated with auditory comprehension(r=0.486 to 0.496,all P<0.05).The comparison between the task state and the resting state further revealed that compensatory connec-tion enhanced in the alpha band in the frontal lobe and limbic system(6 nodes,5 edges,P<0.05)and in the beta band in the frontal,temporal,parietal,occipital lobes and limbic system(38 nodes,52 edges,P<0.01)in PSA pa-tients.Conclusion The core network damage characteristics of PSA patients are abnormally decreased global properties across multiple frequency bands and frequency-specific abnormal network reorganization,suggesting the overall brain network efficiency decline coexists with local compensation.This provides an objective basis for the neuroelec-trophysiological evaluation and targeted intervention of PSA.

Objective·To assess the levels of pregnancy-related stress,pre-pregnancy health care behaviors,and coping styles among pregnant women,analyze the influencing factors of pregnancy stress and provide insights for the management of pregnancy health in expectant mothers.Methods·A total of 265 pregnant women receiving treatment at the Obstetrics Clinic of the Affiliated Hospital of Zunyi Medical University from April to August 2022 were included as participants.General information questionnaires,pre-pregnancy health care behavior questionnaires,pregnancy stress scales and simple coping style questionnaires were utilized for data collection.After obtaining the consent of the patients,assessments on pregnancy stress levels,pre-pregnancy health care behaviors,and coping styles were conducted.Results·The overall average score for pregnancy stress among pregnant women was 1.05±0.41.Multiple linear regression analysis revealed that age,number of pregnancies,history of threatened abortion,fetal gender expectations,attending prenatal education classes or reviewing relevant manuals significantly influenced pregnancy-related stresses(P<0.05).The score of pre-pregnancy health care behavior was 10.09±2.63 with proportions indicating high-level,medium-level,and low-level adherence at 17.36%,54.34%,and 28.30%.In pregnant women,the total score for coping styles was 27.22±9.68,with a positive coping dimension score of 17.79±9.84 and a negative coping dimension score of 9.42±7.39.Pearson correlation analyses demonstrated a negative association between pregnancy-related stresses and pre-pregnancy health care behaviors(r=-0.313,P<0.01),and a negative correlation between pregnancy-related stresses and coping styles(r=-0.163,P<0.01),while a positive relationship existed between pre-pregnancy health care behaviors and coping styles(r=0.220,P<0.01).Conclusion·Pregnant women experience moderate levels of pressure during their pregnancies and have suboptimal engagement in preconceptional healthcare practices.Nursing staff should intensify efforts towards disseminating knowledge on preconceptional healthcare practices,thereby empowering women of childbearing age to actively acquire pertinent reproductive-health knowledge prior to conception so that minimizing adverse maternal-infant outcomes,optimizing maternal-infant healthcare strategies,and enhancing overall well-being can be achieved through these measures.

Objective:To assess the methodological and measurement quality of comprehensive assessment tools for evaluating senile dementia, in order to provide evidence-based guidance for clinical selection of the best assessment tool.Methods:Manually searched CNKI, Wanfang Database, VIP Database, SinoMed, PubMed, Embase, Web of Science, Cochrane Library, CINAHL, ProQuest, Ovid and Scopus databases to collect and evaluate comprehensive assessment tool measurements forsenile dementia. For research on academic attributes, the search time limit was from the establishment of the database to January 4th, 2024. Two researchers independently screened the literature and extracted information, used the COSMIN guidelines to evaluate the included assessment tools, and formed final recommendations.Results:A total of 14 articles were included, including 9 comprehensive assessment tools for the elderly with dementia. Among them, the Care Needs Assessment Scale for Alzheimer′s Disease Patients had moderate and above evidence proving that its content validity and internal consistency were "sufficient", so it was a category A strong recommendation. The remaining 8 evaluation tools were all category B recommendations.Conclusions:Among the existing comprehensive assessment tools for the elderly with dementia, the Care Needs Assessment Scale for Alzheimer′s Disease Patients has good reliability and validity. This scale has 4 dimensions and 16 items. However, there are uncertainties and unmentioned measurement properties of the scale in terms of cross-cultural validity/measurement equivalence, stability, measurement error, hypothesis testing, calibration validity, and responsiveness. More evidence is needed in the future to further comprehensively validate and improve it, providing a basis for selecting a more effective, comprehensive and high-quality comprehensive assessment tool for the elderly with dementia.

Objective:To assess the clinical effectiveness and safety of Omalizumab for treating pediatric allergic asthma in real world in China.Methods:The clinical data of children aged 6 to 11 years with allergic asthma who received Omalizumab treatment in 17 hospitals in China between July 6, 2018 and September 30, 2020 were retrospectively analyzed.Such information as the demographic characteristics, allergic history, family history, total immunoglobulin E (IgE) levels, specific IgE levels, skin prick test, exhaled nitric oxide (FeNO) levels, eosinophil (EOS) counts, and comorbidities at baseline were collected.Descriptive analysis of the Omalizumab treatment mode was made, and the difference in the first dose, injection frequency and course of treatment between the Omalizumab treatment mode and the mode recommended in the instruction was investigated.Global Evaluation of Treatment Effectiveness (GETE) analysis was made after Omalizumab treatment.The moderate-to-severe asthma exacerbation rate, inhaled corticosteroid (ICS) dose, lung functions were compared before and after Omalizumab treatment.Changes in the Childhood Asthma Control Test (C-ACT) and Pediatric Asthma Quality of Life Questionnaire (PAQLQ) results from baseline to 4, 8, 12, 16, 24, and 52 weeks after Omalizumab treatment were studied.The commodity improvement was assessed.The adverse event (AE) and serious adverse event (SAE) were analyzed for the evaluation of Omalizumab treatment safety.The difference in the annual rate of moderate-to-severe asthma exacerbation and ICS reduction was investigated by using t test.The significance level was set to 0.05.Other parameters were all subject to descriptive analysis.A total of 200 allergic asthma patients were enrolled, including 75.5% ( n=151) males and 24.5% ( n=49) females.The patients aged (8.20±1.81) years. Results:The median total IgE level of the 200 patients was 513.5 (24.4-11 600.0) IU/mL.Their median treatment time with Omalizumab was 112 (1-666) days.Their first dose of Omalizumab was 300 (150-600) mg.Of the 200 cases, 114 cases (57.0%) followed the first Omalizumab dosage recommended in the instruction.After 4-6 months of Omalizumab treatment, 88.5% of the patients enrolled ( n=117) responded to Omalizumab.After 4 weeks of treatment with Omalizumab, asthma was well-controlled, with an increased C-ACT score [from (22.70±3.70) points to (18.90±3.74) points at baseline]. Four-six months after Omalizumab administration, the annual rate of moderate-to-severe asthma exacerbation had a reduction of (2.00±5.68) per patient year( t=4.702 5, P<0.001), the median ICS daily dose was lowered [0 (0-240) μg vs. 160 (50-4 000) μg at baseline] ( P<0.001), the PAQLQ score was improved [(154.90±8.57) points vs. (122.80±27.15) points at baseline], and the forced expiratory volume in one second % predicted (FEV 1%pred) was increased [(92.80±10.50)% vs. (89.70±18.17)% at baseline]. In patients with available evaluations for comorbidities, including allergic rhinitis, atopic dermatitis or eczema, urticaria, allergic conjunctivitis and sinusitis, 92.8%-100.0% showed improved symptoms.A total of 124 AE were reported in 58 (29.0%) of the 200 patients, and the annual incidence was 0(0-15.1) per patient year.In 53 patients who suffered AE, 44 patients (83.0%) and 9 patients (17.0%) reported mild and moderate AE, respectively.No severe AE were observed in patients.The annual incidence of SAE was 0(0-1.9) per patient year.Most common drug-related AE were abdominal pain (2 patients, 1.0%) and fever (2 patients, 1.0%). No patient withdrew Omalizumab due to AE. Conclusions:Omalizumab shows good effectiveness and safety for the treatment of asthma in children.It can reduce the moderate-to-severe asthma exacerbation rate, reduce the ICS dose, improve asthma control levels, and improve lung functions and quality of life of patients.

Objective:To investigate the application of "three-dimensional knowledge-objective" teaching combined with immersive clinical experience in nursing practice teaching in the operating room of department of ophthalmology and otorhinolaryngology.Methods:A total of 86 nursing students who received practice teaching in the operating room of Department of Ophthalmology and Otorhinolaryngology in our hospital were selected as research subjects and were divided into control group and observation group using a simple random number table, with 43 students in each group. The students in the control group received traditional teaching, and those in the observation group received "three-dimensional knowledge-objective" teaching and immersive clinical experience. The two groups were assessed in terms of the effectiveness of classroom teaching, nursing quality score, and the score of the ability to handle nurse-patient dispute. SPSS 22.0 was used to perform the chi-square test and the t-test. Results:After training, both groups had significant increases in the scores of basic nursing, specialized nursing, equipment management, equipment coordination ability, patrol coordination ability, and document recording ability and the total score of all dimensions, and the observation group had significantly higher scores than the control group ( P<0.05). After training, both groups had significant increases in the scores of dispute identification ability, the ability of emergency response to dispute, nurse-patient communication skills, the awareness of nursing laws and regulations, and psychological stress adjustment ability and the total score of all dimensions, and the observation group had significantly higher scores than the control group ( P<0.05). Conclusion:In the nursing practice teaching in the operating room of the department of ophthalmology and otorhinolaryngology, "three-dimensional knowledge-objective" teaching combined with immersive clinical experience can improve the effectiveness of classroom teaching, enhance nursing quality, and strengthen the ability to handle nurse-patient dispute.
