Fungal infections have emerged as a critical public health issue endangering human health. However, the existing arsenal of antifungal agents is limited in diversity and is commonly plagued by drawbacks including narrow antimicrobial spectrums and the frequent emergence of drug resistance, which severely compromises the efficacy of clinical treatments. Pathogenic fungi can develop extensive adaptability to currently available drugs through multiple mechanisms, which are mainly manifested in three aspects: drug resistance, tolerance and persistence. The molecular mechanisms and regulatory pathways underlying drug resistance, tolerance and persistence in pathogenic fungi were systematically summarized in this review, and the counteractive strategies such as combination therapy and the development of novel antifungal agents were further discussed, which aimed to provide theoretical basis and practical reference for the precision treatment of fungal infections.

Objective To determine the material basis of the antioxidant activity of Mori Folium by examining the spec-trum-effect relationship.Methods High-performance liquid chromatography(HPLC)was utilized to establish the fingerprints of Mori Folium.The antioxidant activity of Mori Folium was assessed using the 1,1-diphenyl-2-picrylhydrazyl(DPPH)radical scavenging assay and other related indicators.The spectrum-effect relationship of antioxidation was analyzed using gray relational analysis,bivariate correlation analysis,and partial least squares regression analysis.Molecular docking techniques were employed to predict potential interaction targets.Results HPLC fingerprints for 13 batches of Mori Folium were established,and thirteen common peaks were marked,with similarities ranging from 0.932 to 0.998.Nine common peaks were identified by comparing them to reference substances.Differences in antioxidant activity were observed among the different batches of Mori Folium.Based on the analysis of the spectrum-effect relationship,chemical components such as chlorogenic acid,cryptochlorogenic acid,rutin,and iso-chlorogenic acid B were found to contribute significantly to the antioxidant activity.These components may exert their effects by binding to several antioxidant protein targets,such as XOD,NO-1,and PPAR-α.This implies that Mori Folium might exert its an-tioxidant action via multiple components and targets.Conclusions By integrating the fingerprint and antioxidant activity of Mori Folium,the contributions of individual components to its antioxidant activity were determined.This study provides an experi-mental basis for elucidating the substances responsible for the antioxidant activity of Mori Folium and for establishing quality con-trol methods.

Primary aldosteronism(PA) is the most common endocrine cause of secondary hypertension and is characterized by hypertension, hypokalemia, suppressed renin, and inappropriately elevated aldosterone. Increasing evidence indicates disturbances in calcium homeostasis among patients with PA. The calcium-regulatory system encompasses calcium and phosphate, parathyroid hormone(PTH), and vitamin D. Patients with PA frequently exhibit hypocalcemia, hypophosphatemia, elevated PTH, and reduced vitamin D levels. Clarifying the contribution of calcium dysregulation to PA pathogenesis is clinically relevant for mitigating target-organ damage. This review summarizes: (1) the role of aberrant calcium signaling in the development of PA; (2) characteristic features of calcium homeostasis in PA; and (3) the interactions between the renin-angiotensin-aldosterone system(RAAS) and calcium-regulatory pathways. Overall, abnormalities in calcium signaling appear integral to the pathogenesis of PA, and disrupted calcium homeostasis may aggravate target-organ injury in affected patients.

Objective:To investigate the effects and molecular mechanisms of Wilms tumor 1-associated proteins(WTAP)on the cell biological properties of esophageal squamous cell carcinoma(ESCC)cells.Methods:31 pairs of ESCC tissues and their paired paracancerous tissues that were surgically resected at the Second Clinical Medical College of Chuanbei Medical College between September 2019 and April 2021 were collected.The esophageal cancer cells KYSE30,KYSE410,KYSE150,KYSE510,TE-1,and normal human esophageal epithelial cells HET-1A were routinely cultured.Transfection reagents were used to transfect si-NC,si-WTAP#1 and si-WTAP#2 nucleic acids into KYSE150 and KYSE510 cells.The cells were divided into si-NC,si-WTAP#1 and si-WTAP#2 groups.The expressions of WTAP and MAP3K9 mRNA were detected in the cells of each group by qPCR assay.CCK-8 assay,clone formation assay,and scratch healing assay,Transwell assay were employed to detect the effects of knockdown of WTAP expression on ESCC cell proliferation,migration,invasion and apoptosis.WB assay was used to detect the expressions of WTAP,MAP3K9,EMT and MAPK pathway-related proteins in ESCC cells of each group knocked down of WTAP;immunohistochemistry to detect the expression of WTAP proteins in ESCC tissues,immunoprecipitation of methylated RNA(MeRIP)-qPCR assay to detect the level of MAP3K9 m6A in ESCC cells,actinomycin D assay to detect the stability of mRNA of MAP3K9,and database data to analyze the expression,target genes,functional enrichment,and interacting RNA of WTAP.Results:WTAP was highly expressed in ESCC tissues and cells(P<0.05 or P<0.01 or P<0.001)and correlated with the degree of differentiation(P<0.01);the expression of WTAP mRNA and its protein were successfully knocked down in KYSE150 and KYSE510 cells(P<0.01 or P<0.001);the knockdown of WTAP significantly inhibited the proliferation,migration and invasion of KYSE150 and KYSE510 cells(P<0.05 or P<0.01 or P<0.001),and promoted the apoptosis of KYSE150 and KYSE510 cells(P<0.05 or P<0.01).Knockdown of WTAP resulted in a significant decrease in the m6A level of MAP3K9(P<0.05),and its mRNA expression level and mRNA stability were both significantly reduced(P<0.05).Database data analysis showed that WTAP target genes clustered in the MAPK signaling pathway;the expression levels of MAP3K9,p-ERK,N-cadherin,and MMP9 were significantly reduced(P<0.05 or P<0.01),and the expression level of E-cadherin was significantly elevated(P<0.05 or P<0.01)in the KYSE150 and KYSE510 cells after knockdown of WTAP.Conclusions:WTAP is highly expressed in ESCC tissues and cells and correlates with their differentiation.It promotes the stability of MAP3K9 mRNA through m6A modification,activates the MAPK pathway and thus promotes the malignant biological behaviors of ESCC cells.

Objective:To identify the risk factors for acute graft-versus-host disease (aGVHD) in patients with acute myeloid leukemia (AML) undergoing haploidentical hematopoietic stem cell transplantation (HID-HSCT) .Methods:A total of 141 AML patients who underwent HID-HSCT at the Institute of Hematology & Blood Diseases Hospital, Chinese Academy of Medical Sciences, from January 2020 to July 2021 were included. The cumulative incidence of aGVHD was analyzed using the Fine-Gray competing risk model, with relapse and death as competing events, to compare differences between groups. Potential risk factors were evaluated by univariable and multivariable Cox proportional hazards regression analyses to determine their independent effects on aGVHD.Results:Among the 141 patients, 86 (61.0%) were male and 55 (39.0%) were female, with a median age at transplantation of 34 years. Within 100 days post-transplant, 59 patients developed grade Ⅱ-Ⅳ aGVHD, whereas 86 patients experienced no or grade Ⅰ aGVHD (the grade 0-Ⅰ aGVHD group) . Survival analysis showed that the 3-year overall survival was 68.7% (95% CI: 57.7%-81.9%) in the grade Ⅱ-Ⅳ aGVHD group, compared with 78.8% (95% CI: 70.4%-88.3%) in the grade 0 - Ⅰ aGVHD group, with the difference not being statistically significant ( P=0.190) . Univariable analysis identified donor age ( P=0.020, HR=1.020, 95% CI: 1.000-1.040) and the female donor-male recipient sex combination ( P=0.033, HR=1.980, 95% CI: 1.160-3.380) as risk factors for grade Ⅱ-Ⅳ aGVHD. Multivariable analysis confirmed that donor age ( P=0.005, HR=1.026, 95% CI: 1.008-1.047) and the female donor-male recipient sex combination ( P=0.002, HR=2.339, 95% CI: 1.354-4.037) were independent risk factors for aGVHD. Patients receiving grafts from donors aged >45 years had a significantly higher 100-day cumulative incidence of grade Ⅱ-Ⅳ aGVHD compared with those receiving grafts from donors ≤45 years [54.7% (95% CI: 42.3%-67.0%) vs 31.6% (95% CI: 21.0%-42.1%) , P=0.006]. Similarly, patients with the female donor-male recipient sex combination had a higher 100-day cumulative incidence of grade Ⅱ-Ⅳ aGVHD than those with other sex combinations [56.8% (95% CI: 40.4%-73.1%) vs 36.9% (95% CI: 27.5%-46.3%) , P=0.015]. Conclusion:Older donor age and the female donor-male recipient sex combination remain independent risk factors for aGVHD in patients with AML undergoing HID-HSCT.

Objective To apply a random forest model combined with logistic regression in the understudied area of pneumoconiosis complications,and to investigate the incidence and risk factors of pneumoconiosis complicated by bacterial pneumonia,and the effect of concomitant bacterial pneumonia on the survival and prognosis of patients with pneumoconiosis.Methods Pneumoconiosis patients admitted to the West China Fourth Hospital,Sichuan University,between January 2018 and April 2022 were enrolled and divided into a group of those with only pneumoconiosis and another group of those with pneumoconiosis complicated by bacterial pneumonia.Univariate analyses,including chi-squared test,t-test,or rank sum test,were conducted to examine the differences between the groups.A random forest model was used to screen the variables,and the risk factors of pneumoconiosis complicated by bacterial pneumonia were identified by stepwise forward logistic regression method.Cox regression was applied to the survival data to assess the effect of concomitant bacterial pneumonia on the survival and prognosis of pneumoconiosis patients.Results Among the 742 pneumoconiosis patients,536 cases(72.24%)had concomitant bacterial pneumonia.Among the 55 deaths,36 cases(65.45%)had concomitant bacterial pneumonia.Univariate analysis showed statistically significant differences in age,duration of disease,lung function,duration of exposure,lung lavage,pulmonary tuberculosis,and emphysema between the two groups(P<0.05).The variables were screened using the random forest model,and the risk factors were ranked in a descending order of their importance—the types of dust,duration of exposure,lung function,lung lavage,and pulmonary tuberculosis.After screening,multivariate logistic regression analysis showed that the types of dust(compared with silica dust,silicate dust:odd ratio[OR]=8.100,95%CI,1.386-47.331;carbon dust:OR=1.728,95%CI,1.034-2.887;artificial inorganic dust:OR=2.138,95%CI,1.146-3.988),impaired lung function(compared with undamaged lung function group,the group of patients with mild,moderate,and moderately severe damage:OR=2.292,95%CI,1.482-3.544),and pulmonary tuberculosis(OR=1.559,95%CI,1.071-2.271)were risk factors for pneumoconiosis complicated by bacterial pneumonia.The median follow-up was 30.0 months,ranging from 1.0 month to 64.0 months.Cox regression analysis showed that the mortality risk for pneumoconiosis patients with concomitant bacterial pneumonia was 2.369 times higher than that for patients without bacterial pneumonia(95%CI,1.286-4.367).Conclusion Pneumoconiosis patients are susceptible to bacterial pneumonia and are influenced by multiple risk factors.Concomitant bacterial pneumonia markedly affects the patient prognosis.

Objective To develop and validate a"quick self-assessment questionnaire for cochlear implant out-come(QSACI)".Methods A research team,composed of audiologists,otolaryngologists,data analysis experts,and cochlear implant(CI)recipients,was formed to establish objectives,research subject criteria,and framework of the QSACI.An item pool was creaed through literature review and brainstorming.Question items were evaluated and screened,and the framework and answer options of the questionnaire were established.The comprehensibility,etc.,was analyzed and refined through pilot test,interviews,and expert consultation,leading to the development of the final version.A total of 39 post-lingually deafened adults with known stable outcomes completed the question-naire.The split-half and test-retest reliabilty of the questionnaire was analyzed,and the validity was quantitatively analyzed by comparing scores with the categories of auditory performance(CAP)scores.Results The initial item pool of the questionnaire had 18 items,and the final questionnaire consisted of 12 questions in four dimensions:com-munication status,audiological status,medical factors,and other factors.The average score of 39 recipients was 88.81±6.17 and CAP was 6.19±0.94.The questionnaire showed good reliability and validity,with a Cronbach's alpha coefficient of 0.71 and a test-retest reliability of 0.824(P＜0.05).The criterion-related validity,assessed by the correlation between the self-assessment questionnaire scores and CAP scores,showed a significant moderate pos-itive correlation(r=0.512,P＜0.05).The correlation coefficient between self-assessment and professional assess-ment was 0.720(P＜0.05),indicating a significant correlation.The area under the receiver operating characterstic(ROC)curve was 0.82(P＜0.05),the cutoff values corresponding to the maximal Youden index were 82.5 and 88.6,therefore score of 85 was taken as the median threshold score of judgement.Conclusion The QSACI reflects the post-imlplant outcomes,and it can serve as a tool for people with postlingually deafness and their families to un-derstand the eligbility of CI and the expected outcomes,helping to establish realistic expectations before CI surgery.

Alcohol use disorder(AUD)is a common mental disorder and physiological disease impac-ting millions globally.Although multiple studies have explored the causes and treatments of AUD,its exact mechanisms remain poorly understood.The development of lipidomics technology provides a new perspective for studying AUD and can be used to investigate its biological mechanisms.This review summarizes recent ap-plications and progress of lipidomics in AUD research,as well as its potential value in prevention and treat-ment strategies.
