Objective To analyze the characteristics and drug resistance of pathogenic bacteria isolated from patients undergoing solid organ transplantation(SOT)at West China Hospital,Sichuan University in re-cent years,in order to provide a basis for empirical anti infective treatment after SOT surgery.Methods A retrospective analysis was conducted on the isolation of major pathogens and their resistance to common anti-biotics from various specimens collected from patients undergoing kidney transplantation(KT),liver trans-plantation(LTx),and lung transplantation(LT)at West China Hospital,Sichuan University from 2017 to 2022.Results A total of 1 077 non-duplicate strains of pathogens were isolated from the samples of patients with infections after SOT surgery during the 6-year period,of which approximately 74.8％(806/1 077)were Gram negative bacteria and 25.2％(271/1 077)were Gram positive bacteria.There were differences in the distribution of pathogenic bacteria among different types of SOT groups and different specimens.Compared to E.coli isolated from urine specimens,the strains of E.coli isolated from non-urinary specimens exhibited a higher resistance rate to common antimicrobial drugs(P＜0.05).The resistance rate of E.coli to β-lactam/β-lactamase inhibitor combinations(cefoperazone/sulbactam and piperacillin/tazobactam)in the LTx group was significantly higher than that in the KT group(P＜0.05).The overall proportion of multidrug-resistant bac-teria after SOT surgery was 11.3％(122/1 077).The proportion of carbapenem resistant Acinetobacter bau-mannii and carbapenem resistant Pseudomonas aeruginosa among the same group and type of pathogens in the LTx group(93.8％,37.5％)was significantly higher than that in the KT group(55.8％,9.2％).Conclusion The specimen types and strain distribution of pathogenic bacteria after different types of SOT surgery are different.The same pathogenic bacteria have different antibiotic resistance among different types of SOT groups and specimens.Therefore,it is necessary to strengthen the pathogen examination after different types of SOT and optimize the anti infection treatment plan related to transplantation based on drug sensitivity re-sults.

Objective:To explore the formulation patterns and potential targets of traditional Chinese medicine (TCM) in the treatment of pneumoconiosis using data mining, network pharmacology, and Mendelian randomization (MR) .Methods:In November 2023, prescription data for TCM compound treatments of pneumoconiosis from the past five years were retrieved from the China National Knowledge Infrastructure (CNKI), Wanfang, and VIP databases. The formulation patterns of TCM for pneumoconiosis were analyzed based on drug frequency, association rules, and cluster analysis, followed by the identification of core drugs. Network pharmacology and MR analysis were then applied to determine the potential targets for pneumoconiosis treatment.Results:A total of 100 TCM prescriptions were included, involving 182 herbs, with 15 high-frequency herbs. A total of 24 strong association rules were identified, including 16 herbs. Cluster analysis identified three groups of drug combinations. The core drug combination, "Astragalus Root-Codonopsis Root-Tangkuei-Chinese Magnolia Vine Fruit-Danshen Root-Prepared Rehmannia Root" was determined, which interacted with 47 common targets associated with pneumoconiosis. Further protein-protein interaction (PPI) analysis identified 18 core targets, and MR analysis confirmed that Caspase-3 (CASP3) and Cathepsin B (CTSB) were risk factors for pneumoconiosis ( OR=1.35, 1.44; P=0.038, 0.038) . Conclusion:The core drug combination for the treatment of pneumoconiosis with TCM is "Astragalus Root-Codonopsis Root-Tangkuei-Chinese Magnolia Vine Fruit-Danshen Root-Prepared Rehmannia Root". The medication mainly focuses on tonifying lung qi, moistening dryness and stopping coughing, circulating blood and transforming stasis, which are supplemented with herbs for nourishing yin and moistening dryness, warming yang and dissipating cold. Finally, the key targets for treating pneumoconiosis are screened out, providing an important basis for the development of therapeutic drugs for it.

Objective:To explore different types of psychological reactions of spouses of young and middle-aged breast cancer patients and their influencing factors based on potential profile analysis, so as to provide reference for targeted intervention in clinical practice.Methods:A cross-sectional investigation method was used to select the spouses of middle-aged and young patients with breast cancer who were hospitalized in the Second Affiliated Hospital of Guilin Medical University, Quanzhou County People's Hospital, and Bobai County People's Hospital from January 2023 to June 2024. General Data Questionnaire, Spousal Psychological Response Scale of Breast Cancer Patients, Perceived Partner Responsiveness Scale and Perceptive Social Support Scale were used to investigate. The potential profile analysis of spousal psychological reaction of young and middle-aged breast cancer patients was carried out, and the influencing factors of different categories were analyzed by ordered multiple Logistic regression.Results:A total of 232 questionnaires were distributed, and 211 valid questionnaires were collected, with an effective response rate of 91.0%.The spouses of 211 middle-aged and young patients with breast cancer were 30-59 (43.25 ± 2.58) years old. The total psychological response score was (69.96 ± 8.36). The low psychological response high coping group accounted for 24.6% (52/211), the moderate psychological response group accounted for 33.2% (70/211), and the high psychological response low coping group accounted for 42.2% (89/211). The results of ordered multiple Logistic regression analysis showed that cumulative care time, tumor stage of patients, perceived partner responsiveness, and perceived social support were the influencing factors of potential categories of psychological responses of spouses of young and middle-aged breast cancer patients ( OR values were 0.014-0.304, all P<0.05). Conclusions:There is heterogeneity in the psychological reactions of spouses of young and middle-aged breast cancer patients. According to the characteristics of the classification, the nursing staff should formulate targeted intervention strategies, focusing on improving the perceived partner responsiveness, establishing an effective social support system, and reducing the level of psychological response.

Objective:To evaluate the value of Treponema pallidum ( Tp)-specific antibody index in the diagnosis, staging, and typing of neurosyphilis (NS). Methods:Fifty patients diagnosed with NS at the West China Hospital of Sichuan University from March 2020 to December 2022 were recruited as the experimental group, and 50 non-NS syphilis patients were enrolled during the same period as the control group. Cerebrospinal fluid (CSF) and matched serum samples along with clinical data were collected. Clinical and Laboratory Standards Institute (CLSI) EP06-Ed2 file was used to analyze the linear range of electrochemiluminescence immunoassay for Tp-specific antibody detection, and the Tp antibody index was calculate for all subjects. The correlation of Tp antibody index, IgG index, IgG synthesis rate, and albumin quotient with other clinical indicators was evaluated by the coefficient of correlation, and the diagnostic efficacy of these indicators in NS was analyzed using the receiver operating characteristic (ROC) curve. Results:All the deviations from linearity of electrochemiluminescence immunoassay for detecting Tp antibodies in serum and CSF samples were within the allowable deviation from linearity. Compared with the non-NS group, the NS group showed a significant increase in the Tp antibody index ( P<0.05), with no significant differences observed among the groups of different subtypes, severity, or receiving treatment or not ( P>0.05). Tp antibody index, IgG index, and IgG synthesis rate were positively correlated with serum Tp antibody, CSF Tp antibody, trace protein, and nucleated cell count ( P<0.05). Taking 14.99 as the cut-off value for NS diagnosis, the diagnostic sensitivity of Tp antibody index was 74.0% (95%CI: 60.5%-84.1%), and the specificity was 94.0% (95%CI: 83.8%-98.4%), with the area under the ROC curve of 0.897, which was larger than that of albumin quotient, IgG index, and IgG synthesis rate. Conclusions:This study finds a significant increase in the Tp antibody index in NS patients with good diagnostic sensitivity and specificity, providing reference for the diagnosis of NS.

Cerebrospinal fluid (CSF) laboratory tests are important for diagnosing central nervous system (CNS) diseases. Research on intrathecal immunoglobulin-related indexes has gradually attracted attention. The antibody index, which corrects for the effect of individual blood-brain barrier function on CSF antibody test results, is of great significance in the differential diagnosis, efficacy monitoring and prognostic assessment of CNS diseases. It is expected to become a new index for the diagnosis of CNS diseases. This article reviews the concept of antibody index and the research progress of differential diagnosis and treatment of various CNS diseases in order to provide references for the diagnosis, efficacy monitoring and disease progression assessment of CNS diseases.
