This paper presents a case of interstitial lung disease(ILD)during anti-tumor therapy in an elderly breast cancer patient,along with the subsequent glucocorticoid treatment course.Based on the patient's symptoms,signs and comprehensive evaluation of laboratory and imaging findings,and review of relevant literature,the ILD was suspected to be associated with abemaciclib.The causal relationship was determined as highly likely,according to the Common Terminology Criteria for Adverse Events,the severity of the ILD was evaluated as grade 2.The abemaciclib were discontinued and glucocorticoids were administered for anti-inflammation,supplemented with rabeprazole for gastric protection.During the treatment,disease recurrence occurred,which was considered related to overly rapid tapering of glucocorticoid dosage,prompting subsequent dose adjustment and slow reduction of glucocorticoids.Follow-up showed that the patient's ILD had improved.Clinical pharmacists assisted physicians in the differential diagnosis of adverse drug reactions and provided pharmaceutical care,participated in adjusting treatment plans,delivered medication education to patients,and ensured the safety and effectiveness of drug therapy.

OBJECTIVE To explore the distribution of pathogens isolated from the thoracoscopic lobectomy patients with postoperative pulmonary infections and observe the expressions of maternal expression gene 3(MEG3)/microribonucleic acid-223(miR-223)/nucleotide-binding oligomerization domain-like receptor protein 3(NLRP3)axis in peripheral blood.METHODS Totally 48 lung cancer patients who underwent thoracoscopic lobec-tomy and had postoperative pulmonary infections in the First Affiliated Hospital of Guangzhou University of Chi-nese Medicine from Jun.2021 to Jun.2024 were assigned as the infection group,meanwhile,31 lung cancer pa-tients who underwent thoracoscopic lobectomy but did not have postoperative infections were chosen as the no in-fection group.The sputum specimens were collected from the infection group,the distribution of isolated patho-gens was analyzed.The clinical data and the expression MEG3,miR-223 and NLRP3 were observed and compared between the two groups.The values of MEG3,miR-223 and NLRP3 in prediction of the postoperative infections were analyzed by receiver operating characteristic(ROC)curves.RESULTS Totally 63 strains of pathogens were i-solated from the 48 thoracoscopic lobectomy patients with postoperative pulmonary infections,33(52.38％)of which were gram-negative bacteria,25(39.68％)were gram-positive bacteria,and 5(7.94％)were fungi.There were significant differences in age,diabetes mellitus,chronic obstructive pulmonary disease(COPD),operation duration,and expression levels of MEG3,miR-223 and NLRP3 between the infection group and the no infection group(P＜0.05).ROC curve analysis showed that the areas under the curves of MEG3,miR-223 and NLRP3 and the joint detection of the three indexes were 0.861,0.760,0.912 and 0.968,respectively,in prediction of the post-operative pulmonary infections,and the predictive efficiency of the joint detection was highest(P＜0.05).CONCLUSIONS The gram-negative bacteria are dominant among the pathogens isolated from the thoracoscopic lo-bectomy patients with postoperative pulmonary infections,the occurrence and progression of the infections may be closely associated with the activation of MEG3/miR-223/NLRP3 axis.The joint detection of the three indexes can effectively predict the postoperative pulmonary infections in the thoracoscopic lobectomy patients.

BACKGROUND:Compared with conventional repetitive transcranial magnetic stimulation,Theta burst transcranial magnetic stimulation(TBS)has attracted extensive attention from scholars in various fields due to its advantages of short stimulation time,high efficiency,good safety and long-lasting effect,and the research popularity continues to rise.OBJECTIVE:Through the visual bibliometrics analysis of international TBS research in the past 20 years,to sort out the development context of TBS research,summarize the research status,reveal research hotspots and development trends,and provide reference for subsequent research.METHODS:Relevant studies on TBS from January 2005 to June 2024 were searched in the Web of Science Core Collection database.CiteSpace software was used to perform annual publication volume analysis,co-occurrence analysis of countries,institutions and authors,and co-citation analysis of references,journals and authors,keywords co-occurrence,clustering,time evolution and emergence analysis,and so on,and draw the visual knowledge map.RESULTS AND CONCLUSION:(1)After screening,a total of 1914 papers were included in the study,and the amount of TBS research has shown an overall increasing trend over the past 20 years,and it is expected to continue to be a hot topic of research in the future.(2)The top three countries in terms of number of publications are the United States,China and Italy,and the top three institutions are the University of Toronto,the University of London and Harvard Medical School.Pascual-leone Alvaro from Harvard Medical School has the most research achievements,and HUANG YZ from Chang Gung University has the most citations.NEURON is the most influential core journal.(3)Analyses of high-frequency keywords,highly cited references and clustering topics showed that the research hotspots of TBS in the past 20 years mainly focus on the mechanism of TBS on synaptic plasticity and neurophysiological activity,the effect of TBS on stimulating targets in different brain regions(including the motor cortex,dorsolateral prefrontal cortex,anterior cingulate cortex and cerebellum,etc.),and the therapeutic effect of TBS on neurological and psychiatric diseases(including depression,Parkinson's disease movement disorder,post-stroke movement disorder and cognitive impairment,and Alzheimer's disease memory disorders).(4)Keyword burst,literature emergence and keyword temporal evolution analyses showed that"major depression,application guidelines,rating scale,efficacy,disorder,refractory depression,meta-analysis,etc."are not only current research hotspots,but also future research trends.(5)In the future,TBS research should strengthen the regional cooperation of core authors and institutions,explore the clinical application in the treatment of refractory diseases,and realize the precision,personalization and optimization of TBS application by combining cutting-edge technologies and optimizing stimulus parameters,so as to solve more clinical problems.
