The assessment of adverse drug events is an important basis for clinical safety evaluation and post-marketing risk control of drugs,and its causality assessment is gaining increasing attention.The existing methods for assessing the causal relationship between drugs and the occurrence of adverse reactions can be broadly classified into three categories:global introspective methods,standardized methods,and probabilistic methods.At present,there is no systematic introduction of the operational details of the various methods in the domestic literature.This paper compares representative causality assessment methods in terms of definition and concept,methodological steps,industry evaluation and advantages and disadvantages,clarifies the basic process of determining the causality of adverse drug reactions,and discusses how to further improve the adverse drug reaction monitoring and evaluation system,with a view to providing a reference for drug development and pharmacovigilance work in China.

Objective This study aimed to investigate the effect of stage Ⅰ comprehensive cardiac rehabili-tation in patients with acute ST elevation myocardial infarction(STEMI)after emergency percutaneous coronary intervention(PCI).Methods A total of 72 patients with acute ST-segment elevation myocardial infarction combined with PCI admitted to the Department of Cardiovascular Medicine of Beijing Electric Power Hospital of State Grid Corporation from June 2021 to June 2022,which were selected as the research objectsand divided into control group and observation group randomly(36 cases in each group).The control group was treated with routine nursing and health education,and the observation group with stage Ⅰ comprehensive cardiac rehabilitation,including initial assessment(cardiovascular comprehensive assessment),exercise training(exercise training and breathing train-ing),daily activity suggestions and health education,discharge assessment(six-minute walking test and Barthel index assessment).The score of Barthel index(BI)at discharge,the 6-minute walking test distance(6MWD)at discharge,the incidence of major adverse cardiovascular event(MACE)during hospitalization and within one month of discharge,and the length of stay were compared between the two groups.Results After intervention,the six-minute walking test distance(6MWD)and Barthel index(BI)score in the observation group were better than those in the control group,the difference was statistically significant(P<0.05).The incidence of major adverse cardiovascular events(MACE)during hospitalization and one month after discharge was lower in the observation group than in the control group,and the difference was statistically significant(P<0.05).The length of hospital-ization in observation group was lower than that in control groupbut there was no statistical difference(P>0.05).Conclusion The application of phase Ⅰ comprehensive cardiac rehabilitation training in patients with acute ST-segment elevation myocardial infarction combined with emergency PCI could improve the patients'exercise ability,improve their ability of daily activity,reduce the incidence of major adverse cardiovascular events(MACE)in the early stage of the disease,facilitate the patients to return to their families and society as soon as possible,and improve their quality of life.It has high clinical application value.

BACKGROUND: The effects of acupuncture have varied in different randomized controlled trials (RCTs), and there are many factors that influence treatment effect of acupuncture in different outcomes, with conflicting results. OBJECTIVE: To identify factors and their impact on the treatment effect of acupuncture in different outcomes. METHODS: Acupuncture RCTs were searched from 7 databases including Medline (PubMed), Embase, Cochrane Central Register of Controlled Trials, China National Knowledge Infrastructure, Wanfang Database, VIP Database, and China Biology Medicine disc between January 1st, 2015 and December 31st, 2019. Eligible studies must compare acupuncture to no acupuncture, sham acupuncture, or waiting lists, and report at least 1 patient-important outcome. A multi-level meta-regression was conducted using a 3-level robust mixed model and univariate analyses were performed for all independent variables, even those excluded from the multivariable model due to collinearities. We used thresholds of 0.2 and 0.4 for the difference of standardized mean differences (SMDs), categorising them as small (<0.2), moderate (0.2-0.4), or large (>0.4) effects. RESULTS: The pain construct analysis involved 211 effect estimates from 153 studies and 14 independent variables. High-frequency acupuncture treatment sessions produced larger effects compared to low-frequency sessions [large magnitude, the difference of adjusted SMDs 0.46, 95% confidence interval (CI) 0.07 to 0.84; P=0.02]. The non-pain symptoms construct analysis comprised 323 effect estimates from 231 studies and 15 independent variables. Penetrating acupuncture showed moderately larger effects when compared to non-penetrating acupuncture (0.30, 95% CI 0.06 to 0.53; P=0.01). The function construct analysis included 495 effect estimates from 274 studies and 14 independent variables. Penetrating acupuncture and the flexible acupuncture regimen showed moderately larger effects, compared to non-penetrating acupuncture and fixed regimen, respectively (0.40, 95% CI 0 to 0.80; P=0.05; 0.29, 95% CI 0.06 to 0.53; P=0.01). CONCLUSIONS High-frequency acupuncture sessions appear to be a more effective approach to managing painful symptoms. Penetrating acupuncture demonstrated greater effect in relieving non-painful symptoms. Both penetrating acupuncture type and flexible acupuncture regimen were linked to significant treatment effects in function outcomes. Future studies should consider the factors that are significantly associated with the effects of acupuncture in patient-important outcomes.

Objective To investigate the attributable risk(AR)of Acinetobacter baumannii(AB)infection in criti-cally ill patients.Methods A multicenter retrospective cohort study was conducted among adult patients in inten-sive care unit(ICU).Patients with AB isolated from sterile body fluid and confirmed with AB infection in each cen-ter were selected as the infected group.According to the matching criteria that patients should be from the same pe-riod,in the same ICU,as well as with similar APACHE Ⅱ score(±5 points)and primary diagnosis,patients who did not infect with AB were selected as the non-infected group in a 1:2 ratio.The AR was calculated.Results The in-hospital mortality of patients with AB infection in sterile body fluid was 33.3％,and that of non-infected group was 23.1％,with no statistically significant difference between the two groups(P=0.069).The AR was 10.2％(95％CI:-2.3％-22.8％).There is no statistically significant difference in mortality between non-infected pa-tients and infected patients from whose blood,cerebrospinal fluid and other specimen sources AB were isolated(P＞0.05).After infected with AB,critically ill patients with the major diagnosis of pulmonary infection had the high-est AR.There was no statistically significant difference in mortality between patients in the infected and non-infec-ted groups(P＞0.05),or between other diagnostic classifications.Conclusion The prognosis of AB infection in critically ill patients is highly overestimated,but active healthcare-associated infection control for AB in the ICU should still be carried out.

Chemokines and their receptors play crucial roles in nervous system diseases,among which the CXC chemokine receptor 3(CXCR3)is an important mediator of intercellular communication.CXCR3 not only participates in inflammatory chemotaxis and malignant behaviors of tumor cells but also regulates the neurologic diseases.CXCR3 and its ligands directly or indirectly contribute to neuroinflammation and neuroimmunity,and potentially serve as therapeutic targets for diseases like multiple sclerosis,Alzheimer's disease,and glioma and so on.This review discusses the expression and impact of CXCR3 and its ligands in neurological diseases such as multiple sclerosis,neurologic tumors,neurodegenerative diseases,and neuropathic pain,as well as their associations with CXCR3 ligands.Understanding the mechanisms linking CXCR3 to these diseases could facilitate its potential as an early diagnostic biomarker and a target for drug intervention,and provide the basis of studying the occurrence and developmant of nervous system disease.

Stress is a non-specific adaptive response of organisms to internal and external stimuli,which helps maintain the homeostasis of the body's internal environment.However,when the stress response exceeds the body's adaptation threshold,a variety of diseases will be induced.The morbidity and mortality of breast cancer rank the highest among female malignant tumors.Professor LIN Yi,the first master of traditional Chinese medicine(TCM)in the field of breast diseases who founded the theory of'treating breast diseases from the perspective of six stagnations',believes that six stagnations are the core pathogenesis of breast cancer,and six stagnations are closely related to the body's stress response system.TCM has unique advantages in adjusting the balance of stress homeostasis.By reviewing the classical TCM theory,the theory of'treating breast diseases from the perspective of six depressions'and the modern stress theory,this paper put forward the theory of'stress-based breast cancer prevention & treatment',and expounded the pathogenesis features,pathogenic characteristics and molecular mechanism of stress factors in mediating the development and progression of breast cancer.Moreover,the core idea and treatment principle based on the regulation of stress homeostasis were proposed,and the prescription and medication guided by the theory of'stress-based breast cancer prevention & treatment'were summarized.The establishment of the theory of'stress-based breast cancer prevention & treatment'enriches the theoretical system of breast cancer in TCM,and is expected to provide a new approach for improving the clinical prognosis of breast cancer patients.

Objective To explore the cut-off value of three dimensional(3D)vena contracta area(VCA)in diagnosing severe tricuspid regrugitation(TR)under different etiologies and its accuracy and practicality in clinical application.Methods From Mar 2019 to May 2021,ninety-two patients with confirmed TR underwent two dimensional(2D)and 3D transthoracic echocardiography.The correlation and consistency between 3D VCA 3D calculated based on the proximal isokinetic surface area(PISA)effective regurgitant orifice area(EROA)was calculated.Comprehensive 2D multi-parameter method was used as a reference method to calculate the cut-off value of the diagnosis of severe TR.Results A total of 85 patients were ultimately included.3D VCA and 3D PISA EROA had similar and acceptable correlations in both primary TR and secondary TR(primary TR:r=0.831,P<0.01;secondary TR:r=0.806,P<0.01).Bland-Altman analysis showed that 3D VCA overestimated TR compared with 3D PISA EROA(62%overestimated in the total patient population,51%overestimated in primary TR,and 74%overestimated in secondary TR).In secondary TR,the cut-off value of 3D VCA for diagnosing severe TR was 0.45 cm2(sensitivity 89%,specificity 82%);combining clinical symptoms,positive 2D PISA EROA results and 3D VCA results for severe TR,the chi-square value was higher than those only included clinical symptoms or incorporated clinical symptoms and positive 2D PISA EROA results(42.168 vs.26.059 and 16.759,P<0.01).Conclusion 3D VCA would overestimate TR,and had high and incremental diagnostic value for evaluating severe TR in secondary TR.

Neurodevelopmental disorders in children have become a significant global public health concern,impacting child health worldwide.In China,the current intervention model for high-risk infants involves early diagnosis and early treatment.However,in recent years,overseas studies have explored novel preventive early intervention strategies for neurodevelopmental disorders in high-risk infants,achieving promising results.This article provides a comprehensive review of the optimal timing,methods,and intervention models of the preventive early intervention strategies for neurodevelopmental disorders in high-risk infants.The aim is to enhance the awareness and knowledge of healthcare professionals regarding preventive early intervention strategies for neurodevelopmental disorders in high-risk infants,facilitate clinical research and application of such interventions in China,and ultimately reduce the incidence of neurodevelopmental disorders in this high-risk population.[Chinese Journal of Contemporary Pediatrics,2024,26(3):297-301]

Objective To investigate the risk factors for bronchopulmonary dysplasia(BPD)in twin preterm infants with a gestational age of<34 weeks,and to provide a basis for early identification of BPD in twin preterm infants in clinical practice.Methods A retrospective analysis was performed for the twin preterm infants with a gestational age of<34 weeks who were admitted to 22 hospitals nationwide from January 2018 to December 2020.According to their conditions,they were divided into group A(both twins had BPD),group B(only one twin had BPD),and group C(neither twin had BPD).The risk factors for BPD in twin preterm infants were analyzed.Further analysis was conducted on group B to investigate the postnatal risk factors for BPD within twins.Results A total of 904 pairs of twins with a gestational age of<34 weeks were included in this study.The multivariate logistic regression analysis showed that compared with group C,birth weight discordance of>25%between the twins was an independent risk factor for BPD in one of the twins(OR=3.370,95%CI:1.500-7.568,P<0.05),and high gestational age at birth was a protective factor against BPD(P<0.05).The conditional logistic regression analysis of group B showed that small-for-gestational-age(SGA)birth was an independent risk factor for BPD in individual twins(OR=5.017,95%CI:1.040-24.190,P<0.05).Conclusions The development of BPD in twin preterm infants is associated with gestational age,birth weight discordance between the twins,and SGA birth.
