Objective To monitor the antifungal resistance of clinical isolates of Candida spp.in the East China region.Methods MALDI-TOF MS or molecular methods were used to re-identify the strains collected from January 2018 to December 2022.Antifungal susceptibility testing was performed using the broth microdilution method.The susceptibility test results were interpreted according to the breakpoints of 2022 Clinical and Laboratory Standards Institute(CLSI)documents M27 M44s-Ed3 and M57s-Ed4.Results A total of 3 026 strains of Candida were collected,65.33％of which were isolated from sterile body sites,mainly from blood(38.86％)and pleural effusion/ascites(10.21％).The predominant species of Candida were Candida albicans(44.51％),followed by Candida parapsilosis complex(19.46％),Candida tropicalis(13.98％),Candida glabrata(10.34％),and other Candida species(0.79％).Candida albicans showed overall high susceptibility rates to the 10 antifungal drugs tested(the lowest rate being 93.62％).Only 2.97％of the strains showed dose-dependent susceptibility(SDD)to fluconazole.Candida parapsilosis complex had a SDD rate of 2.61％and a resistance rate of 9.42％to fluconazole,and susceptibility rates above 90％to other drugs.Candida glabrata had a SDD rate of 92.01％and a resistance rate of 7.99％to fluconazole,resistance rates of 32.27％and 48.24％to posaconazole and voriconazole non-wild-type strains(NWT),respectively,and susceptibility rates above 90％to other drugs.Candida tropicalis had resistance rates of 29.55％and 26.24％to fluconazole and voriconazole,respectively,resistance rates of 76.60％and 21.99％to posaconazole and echinocandins non-wild-type strains(NWT),and a resistance rate of 2.36％to echinocandins.Conclusions The prevalence and species distribution of Candida spp.in the East China region are consistent with previous domestic and international reports.Candida glabrata exhibits certain degree of resistance to fluconazole,while Candida tropicalis demonstrates higher resistance to triazole drugs.Additionally,echinocandins resistance has emerged in Candida albicans,Candida glabrata,Candida tropicalis,and Candida parapsilosis.

Objective:To validate and compare the value of the Status Epilepticus in Pediatric Severity Score (STEPSS) versus PEDSS in assessing the short-term prognosis of children with status epilepticus (SE).Methods:Clinical data of 152 children with SE hospitalized at the First Affiliated Hospital of Zhengzhou University from January 2020 to December 2022 were retrospectively analyzed.According to the STEPSS and PEDSS scores, children with SE were scored and their prognosis was predicted.Receiver operating characteristic (ROC) curves of the 2 scales in assessing the short-term prognosis of SE in children were plotted, and the area under the curve (AUC), optimal cut-off, sensitivity and specificity were calculated, thus validating and comparing the value of the STEPSS versus PEDSS in assessing the short-term prognosis of children with SE.Results:Of the 152 children with SE, 90 were male and 62 were female, with the age of (5.8±3.9) years (1 month to 15 years). There were 112 cases with good prognosis and 40 cases with poor prognosis, involving 13 deaths.The AUC of STEPSS and PEDSS scores in predicting the death in children with SE were 0.908(95% CI: 0.848-0.967) and 0.887(95% CI: 0.831-0.942), respectively, both with the optimal cut-off value of 4.The sensitivity of STEPSS and PEDSS scores in predicting the death in children with SE were 0.740 and 0.846, respectively, and the specificity were 0.745 and 0.835, respectively.There was no significant difference in predicting the death in children with SE between the 2 scales ( P>0.05). In predicting adverse outcomes, the AUC of the STEPSS and PEDSS scores were 0.869(95% CI: 0.800-0.937) and 0.926(95% CI: 0.873-0.979), respectively, both with the optimal cut-off value of 3.The sensitivity of STEPSS and PEDSS scores in predicting adverse outcomes in children with SE were 0.827 and 0.900, respectively, and the specificity were 0.732 and 0.866, respectively.There was significant difference in predicting the adverse outcomes in children with SE between the 2 scales ( P<0.05). Conclusions:Compared with the STEPSS, the PEDSS has a higher application in predicting the short-term treatment outcome of children with SE, which can be used as a routine method to assess the prognosis of children with SE.

Objective:To investigate the rates of low disease activity and clinical remission in patients with systemic lupus erythematosus(SLE)in a real-world setting,and to analyze the related factors of low disease activity and clinical remission.Methods:One thousand patients with SLE were enrolled from 11 teaching hospitals.Demographic,clinical and laboratory data,as well as treatment regimes were collec-ted by self-completed questionnaire.The rates of low disease activity and remission were calculated based on the lupus low disease activity state(LLDAS)and definitions of remission in SLE(DORIS).Charac-teristics of patients with LLDAS and DORIS were analyzed.Multivariate Logistic regression analysis was used to evaluate the related factors of LLDAS and DORIS remission.Results:20.7％of patients met the criteria of LLDAS,while 10.4％of patients achieved remission defined by DORIS.Patients who met LLDAS or DORIS remission had significantly higher proportion of patients with high income and longer disease duration,compared with non-remission group.Moreover,the rates of anemia,creatinine eleva-tion,increased erythrocyte sedimentation rate(ESR)and hypoalbuminemia was significantly lower in the LLDAS or DORIS group than in the non-remission group.Patients who received hydroxychloroquine for more than 12 months or immunosuppressant therapy for no less than 6 months earned higher rates of LLDAS and DORIS remission.The results of Logistic regression analysis showed that increased ESR,positive anti-dsDNA antibodies,low level of complement(C3 and C4),proteinuria,low household in-come were negatively related with LLDAS and DORIS remission.However,hydroxychloroquine usage for longer than 12 months were positively related with LLDAS and DORIS remission.Conclusion:LLDAS and DORIS remission of SLE patients remain to be improved.Treatment-to-target strategy and standar-dized application of hydroxychloroquine and immunosuppressants in SLE are recommended.

Objective: To understand the association of maternal emotional symptoms and parent-child relationship with emotional and behavioral problems (EBPs) in primary school students, so as to provide a reference for the prevention of EBPs in primary school students. Methods: In May 2023, a convenient cluster sampling method was used to select 1 324 students from two primary schools in Hefei City, Anhui Province as the study subjects. The Generalized Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire (PHQ-9), Family Adaptation and Cohesion Evaluation ScalesⅡ (FACES Ⅱ), and Strengths and Difficulties Questionnaire (SDQ) of parental version were used to investigate maternal emotional symptoms, parent-child relationship, and EBPs of primary school students, respectively. Multivariate Logistic regression analysis model was used to analyze the association of different maternal emotional symptoms and parent-child relationship with EBPs of primary school students. Results: The abnormal detection rates of emotional symptoms, conduct problems, hyperactivity disorder, peer problems, prosocial behavior and total difficulties in primary school students were 13.6%, 19.4%, 20.2%, 36.5%, 20.9% and 51.9%, respectively. Multivariate Logistic regression analysis showed that the detection rates of EBPs in primary school students whose mothers had anxiety and depression symptoms with low level of parent-child relationship increased ( OR=1.52-6.97, P <0.01). The combined effect of mothers who had anxiety and depression symptoms with low level of parent-child relationship increased the risk of EBPs in all dimensions of primary school students ( OR=4.07-10.14, P <0.01). After gender stratification, the combined effect of mothers who had anxiety and depression symptoms with low level of parent-child relationship increased the risk of EBPs in all dimensions of boys and girls ( OR=3.71- 10.95 , P <0.01). Conclusions Maternal emotional symptoms and parent-child relationship are associated with EBPs in primary school students. Reducing maternal anxiety and depression symptoms, and improving parent-child relationship are beneficial to reduce the incidence of EBPs problems in primary school students.

Objective:To investigate the role of dopamine receptors in the central amygdala (CeA) in reduction of the anxiety level by propofol in a mouse model of post-traumatic stress disorder (PTSD).Methods:Fifty-six SPF healthy adult male C57BL/6 mice, aged 10 weeks, weighing 20-25 g, were divided into 7 groups ( n=8 each) using a random number table method: control group (C group), PTSD group (P group), PTSD+ propofol group (PP group), PTSD+ fat emulsion group (PF group), PTSD+ propofol+ normal saline group (PPN group), PTSD+ propofol+ dopamine receptor D1 (DRD1) antagonist group (PP+ DRD1-Ant group), and PTSD+ propofol+ DRD2 antagonist group (PP+ DRD2-Ant group). The PTSD model was developed by continuous plantar electric shock for 3 days. Propofol 120 mg/kg was intraperitoneally injected after successful establishment of the model in PP group, and the equal volume of fat emulsion was intraperitoneally injected in PF group. In PPN group, PP+ DRD1-Ant group and PP+ DRD2-Ant group, the equal volume of normal saline, DRD1 antagonist hydrochloride and DRD2 antagonist eticlopride hydrochloride were injected in bilateral CeA regions, respectively, 30 min later the efficacy of drugs reached the peak, and then propofol 120 mg/kg was intraperitoneally injected. The anxiety levels were measured at 4 h (T 1) and day 3 after propofol injection (T 2) by the open field test and elevated cross maze test. Results:Compared with C group, the time spent entering the open and central areas was significantly shortened at T 1, 2, and the number of entering the open and central areas was decreased at T 1, 2 in P group ( P<0.001). Compared with P group, the time spent entering the open and central areas was significantly prolonged at T 1, the number of entering the open and central areas was increased at T 1 ( P<0.001), and no significant change was found at T 2 in PP group ( P>0.05), and no significant change was found in the aforementioned parameters at T 1, 2 in PF group ( P>0.05). Compared with PPN group, the time spent entering the open and central areas was significantly shortened at T 1, and the number of entering the open and central areas was decreased at T 1 in PP+ DRD2-Ant group ( P<0.001), and no significant change was found at T 1 in PP+ DRD1-Ant group ( P>0.05). Conclusions:Activation of DRD2 in the CeA is involved in the process by which propofol reduces the anxiety level of mice with PTSD.
