Objective: To analyze the drug resistance of multidrug-resistant organism (MDRO) among hospitalized children in a children's hospital in Hebei Province from 2019 to 2023, so as to provide the basis for the rational clinical application of antibacterial drugs. Methods: Specimens including sputum, blood, urine, pus, bronchoalveolar lavage fluid, secretions, pleural fluid, and peritoneal fluid of hospitalized children from January 2019 to December 2023 were collected. Pathogen identification and drug susceptibility tests were performed on methicillin-resistant Staphylococcus aureus (MRSA), extended-spectrum β-lactamase-producing Escherichia coli (ESBLs-EC), extended-spectrum β-lactamase-producing Klebsiella pneumoniae (ESBLs-KP), carbapenem-resistant Klebsiella pneumoniae (CRKP), carbapenem-resistant Acinetobacter baumannii (CRAB), carbapenem-resistant Pseudomonas aeruginosa (CRPA) and carbapenem-resistant Escherichia coli (CREC). The department distribution, specimen distribution, and drug resistance of MDROs were analyzed. Results: A total of 279 086 samples were submitted for testing, with 3 512 MDROs detected. Among these, MRSA and ESBLs-EC had relatively high detection rates of 35.76% and 41.50%, respectively. In the internal medicine pediatric patients, 1 869 MDROs were detected, accounting for 53.22%. The main departments were respiratory medicine, neonatology, and intensive care. In the surgical department, 1 643 MDROs were detected, accounting for 46.78%, with the main sources being general surgery and cardiac surgery. The highest numbers of MDROs were detected in sputum, pus, and urine samples, with 1 372, 527, and 494 isolates, representing 39.07%, 15.01%, and 14.07%, respectively. The resistance rates of MRSA to penicillin, oxacillin, and erythromycin were between 81.76% and 100.00%. ESBLs-EC and ESBLs-KP had a resistance rate of 100.00% to ceftriaxone. CRKP had a resistance rate of 100.00% to ampicillin/sulbactam and imipenem. CRAB had a resistance rate of 100.00% to cefoxitin, imipenem, and meropenem. CRPA had a resistance rate of 100.00% to ampicillin/sulbactam, ceftriaxone, cefoxitin, and imipenem. CREC had a resistance rate of 100.00% to imipenem. Conclusions In a children's hospital in Hebei Province, infections with MDROs among hospitalized pediatric patients are primarily caused by MRSA and ESBLs-EC. These infections are mainly distributed in the departments of respiratory medicine, neonatology, intensive care, general surgery, and cardiac surgery, with the highest detection rates in sputum, pus, and urine samples. Additionally, MRSA, ESBLs-EC, ESBLs-KP, CRKP, CRAB, CRPA, and CREC show high resistance rate to most antimicrobial agents.

Depression is increasingly prevalent among adolescents and can profoundly impact their lives. However, the early detection of depression is often hindered by the time-consuming diagnostic process and the absence of objective biomarkers. In this study, we propose a novel approach for depression detection based on an affective brain-computer interface (aBCI) and the resting-state electroencephalogram (EEG). By fusing EEG features associated with both emotional and resting states, our method captures comprehensive depression-related information. The final depression detection model, derived through decision fusion with multiple independent models, further enhances detection efficacy. Our experiments involved 40 adolescents with depression and 40 matched controls. The proposed model achieved an accuracy of 86.54% on cross-validation and 88.20% on the independent test set, demonstrating the efficiency of multimodal fusion. In addition, further analysis revealed distinct brain activity patterns between the two groups across different modalities. These findings hold promise for new directions in depression detection and intervention.

The 5-hydroxytryptamine 2A receptor (5-HT_2AR) is one of the key targets in the development of novel antidepressants. To develop new antidepressants targeting the 5-HT_2A receptor, this study established a high-throughput screening method for drugs targeting the 5-HT_2A receptor based on the principle of detecting calcium flux signals. The immunofluorescence assay and western blotting were employed to evaluate receptor expression levels in the 5-HT_2AR-CHO cell line. The reaction system parameters, including cell seeding density, DMSO concentration, and dye incubation time, were optimized with Z'-factor and signal window values as evaluation indicators. The specificity, precision, stability, and applicability of the method were assessed. Results indicated that the 5-HT_2AR-CHO cell line stably expressed high levels of the 5-HT_2A receptor. The optimized screening method involved a reaction system with 10 000 cells/well, 0.2% DMSO, and 2 h incubation with Calcium 6 dye. The method demonstrated excellent specificity, with inter-batch precision below 10% for the detection of 5-hydroxytryptamine (5-HT) at low, medium, and high concentrations. Testing four compounds that target the 5-HT_2A receptor- agonists 2,5-dimethoxy-4-iodoamphetamine (DOI), 5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT), and lysergic acid diethylamide (LSD), along with the antagonist MDL100907-yielded Z'-factors (at EC₈₀) greater than 0.85 and signal window values over 0.91. The EC₅₀ values of these compounds were in the nanomolar range, and their potency rank order aligned with previously reported data, confirming the reliability of the established method. When being applied to the detection of 38 known active compounds, the method efficiently identified 5-HT_2A receptor agonists and antagonists while showing no response to non-target compounds. In conclusion, this study successfully constructs a high-throughput screening approach for 5-HT_2A receptor-targeting drugs based on calcium flux signals. The method possesses strong specificity, high sensitivity, and robust stability, being suitable for screening antidepressants targeting the 5-HT_2A receptor.

Objective To investigate the distribution of dense fine speckled(DFS)antinuclear antibody(ANA)in different ages,genders,and diseases,and to explore its clinical significance in the diagnosis of auto-immune disease(AID).Methods A retrospective summary was conducted on the clinical basic data of 53520 patients who visited the hospital from January 2022 to April 2024,as well as the results of indirect immunoflu-orescence(IIF)ANA fluorescence karyotype and titer,and immunoblotting ANA spectrum,and the relation-ship between DFS positivity and AID was analyzed.Results Of the 53 520 serum samples,the rate of ANA fluorescence positivity was 32.40％,with DFS-positive samples accounting for 1.18％of all ANA fluores-cence-positive samples.The male-to-female ratio of DFS positives was 1∶1.94,with the highest percentage of 51.9％in the 21-40 age group.Among DFS positive individuals,only 12.14％were clinically diagnosed with AID disease,significantly lower than other ANA fluorescent karyotype positive individuals(23.31％,P＜0.001).The overall positivity rate of ANA spectra using immunoblotting in DFS-positive individuals was 23.54％,which was significantly lower than that in other fluorescent karyotype positive ANA individuals(73.26％,P＜0.001).Moreover,DFS positive individuals were mainly accompanied by antibody positivity such as anti-Ro52 antibodies,which had no diagnostic specificity in AID diagnosis.When comparing DFS posi-tive individuals with similar fluorescence morphology to those with homogeneous nuclear granules and nuclei,at an ANA titer of 1∶100,the proportion of AID patients in homogeneous nuclear granules and nuclei was 20.04％,significantly higher than the proportion of AID patients in DFS positive individuals(9.44％,P=0.001).With the increase of ANA titer,the proportion of AID diseases significantly increased in both karyo-type samples.When the ANA titer of DFS positive samples was increased to ≥ 1∶320,the proportion of AID diseases significantly increased to 30.77％(P=0.002).Conclusion DFS is a rare ANA fluorescent karyo-type,and DFS positive individuals are mainly found in females aged 21-40,mostly non AID patients.Howev-er,high titers of DFS cannot rule out the possibility of AID.In clinical work,special attention should be paid to distinguishing it from the homogeneous nuclear granule type to avoid misdiagnosis.

Objective To investigate the factors influencing the development of extra-pulmonary tuberculosis(EPTB)in patients with viral hepatitis complicated by pulmonary tuberculosis(PTB).Methods A retrospective analysis was conducted on 427 patients with Hepatitis B Virus(HBV)and Hepatitis C Virus(HCV)infections complicated by PTB admitted to the tuberculosis department of Kunming Third People's Hospital from January 2015 to December 2020.Patients were divided into the EPTB complication group(n=72)and the non-EPTB complication group(n=355)based on the presence of EPTB.Clinical treatment data of patients were collected.Univariate and multivariate Logistic regression analyse were used to screen independent risk factors for EPTB as predictive factors.A nomogram prediction model was established for Extrapulmonary Tuberculosis(EPTB)complications in patients with viral hepatitis and Pulmonary Tuberculosis(PTB),evaluated using the Hosmer-Lemeshow test and ROC curve analysis.Results Among the 427 patients,292(68.3%)were male and 135(31.7%)were female,with 72 cases of EPTB,resulting in an incidence rate of 16.86%.In the EPTB group,there were 34 males(47.2%)and 38 females(52.8%).The types of EPTB included tuberculous pleuritis(21 cases,29%),tuberculous peritonitis(16 cases,22%),lymph node tuberculosis(13 cases,18%),tuberculous encephalitis(5 cases,6%),intestinal tuberculosis(6 cases,8%),bone tuberculosis(5 cases,6%),pelvic tuberculosis(3 cases,4%),and genitourinary tuberculosis(3 cases,4%).Multivariate logistic regression analysis showed that gender(OR=0.425,95%CI:0.250-0.722,P=0.02),low triglyceride(TG)levels(OR=0.837,95%CI:0.717-0.978,P=0.025),the tuberculosis-specific antigen A(ESAT-6)(OR=1.007,95%CI:1.003～1.011 were independent influencing factors for EPTB in patients with PTB complicated by HBV and HCV infections.The optimal cutoff value for the nomogram model is 0.192,with a sensitivity of 0.611,specificity of 0.710,Youden index of 0.741,positive likelihood ratio of 2.103,and negative likelihood ratio of 0.548.The Hosmer-Lemeshow test yielded χ2=2.631,P=0.955.ROC curve analysis showed an AUC of 0.693,95%CI:0.629 1～0.7574.Conclusion The prediction model based on gender,low TG levels and ESAT-6 can well predict the occurrence of EPTB to some extent,providing a reference for clinical treatment.

This study aims to evaluate the accuracy of portable hemoglobinometer (Hemocue Hb 201+ hemoglobin analyzer) in patients with maintenance hemodialysis (MHD) and its diagnostic value for anemia. The data of venous hemoglobulin (Hb) and fingertip capillary hemoglobulin (DHb) in MHD patients from Lingnan Hospital, the Third Affiliated Hospital of Sun Yat-sen University were retrospectively analyzed, and the correlation and difference between DHb and Hb and the accuracy of DHb in the diagnosis of anemia were evaluated. A total of 105 patients were included in the study. There was no significant difference between the paired DHb and Hb [(109±21) g/L vs. (108±20) g/L, t=-1.284, P=0.202]. Pearson correlation analysis showed that DHb was positively correlated with Hb ( r=0.929, P<0.001). Linear regression analysis showed that DHb and Hb met the regression equation Hb=0.88×DHb+12.23, and P<0.001. Bland-Altman analysis showed that the differences between the paired DHb and Hb was (1.0±7.8) g/L with the limit of agreement as (-14.2, 16.2) g/L. The mean percentage of the differences in Hb was 1% with limit of agreement as (-13.7%, 15.7%). A DHb of >110 g/L was 0.90 sensitive and 0.83 specific to identify patients with an Hb >110 g/L and its positive and negative predictive values were 0.84 and 0.90, respectively. It suggests that, in MHD patients, Hemocue Hb 201+ analyzer shows good accuracy, and can be used to monitor the Hb trend and serve as a screen method for those reaching target Hb.

Objective To study the clinical and electrophysiological characteristics about ictal facial dystonia of medial temporal lobe epilepsy.Method Data was collected from patients with mesial temporal lobe epilepsy originating from unilateral temporal lobe structures through preoperative evaluation at the Functional Neurology Department of the Second People's Hospital of Shenzhen between July 1,2019 and September 1,2023.All patients did not have seizures for at least 1 year after operation.The ictal symptoms of each patient were analyzed and the patients with ictal facial dystonia were selected and the clinical and electrophysiological characteristics of ictal facial dystonia were summarized.Results Nineteen of 47 patients diagnosed as mesial temporal lobe epilepsy had ictal facial dystonia,of which the electroencephalogram starting at the right side in 11 cases and at the left side in 8 cases.Fifteen patients had the symptom in the first 1/3 period of seizure.Fifteen patients had bilateral symmetrical muscle contraction.Thirteen patients showed with negative expression,5 with neutral expression,and 1 with negative or positive expression in different seizures.None of the patient had the drop of the corners of the mouth.Five patients underwent stereotactic-electroencephalogram(SEEG),including 3 patients with bilateral implantation and 2 patients with unilateral implantation.SEEG showed that the medial temporal structure,insula and orbital lobes were all involved in the onset of ictal facial dystonia.Conclusion The medial temporal lobe epilepsy often present ictal facial dystonia in the first 1/3 period of seizure,with bilaterally symmetrically facial contraction,often accompanied by negative expression,but without drop of the corners of the mouth.The lateralization value of ictal facial dystonia is limited and this symptom involves a wide brain network structure.

Objective To summarise a clinical experience of nursing care for 3 children who were treated with ECMO for sepsis and complicated with fulminant myocarditis.Methods Clinical data in nursing cares for 3 children treated with ECMO for sepsis and complicated with fulminant myocarditis were collected and analysed,with the spotted difficulties in nursing care and proposed coping strategies.Results The 3 children survived and were transferred out of the(pediatric intensive care unit,PICU)with stable vital signs and haemodynamics after emergency treatment with ECMO and continuous renal replacement therapy(CRRT).Conclusion Children with sepsis leading to myocardial depression and subsequent heart failure require close observation of the changes and consequently specialised cares after having initiated an ECMO in emergency treatment.This includes ensuring proper fixation of the cannulas,managing anticoagulation,monitoring the speed,flow rate and pressure of ECMO,management of body temperature,skin care,sedation and pain,as well as prevention of complications.These nursing care measures would improve the survival rate after the treatment of ECMO.

Objective To summarize the clinical,electrophysiological and imaging features of frontal opercular epilepsy.Methods A retrospective analysis was conducted on 5 cases with frontal opercular epilepsy,who were treated at the Department of Functional Neurology,Shenzhen Second People's Hospital from December 2020 to December 2022.Among these cases,4 cases were underwent stereotactic-EEG(SEEG)guided radiofrequency thermocoagulation.The clinical,electrophysiological,and imaging characteristics of these 5 cases were summarized.Results The 5 cases had an onset age ranging from 2 to 17 years and a disease duration ranging from 1 to 20 years.All of them experienced daily seizures,especially at night.The seizure duration was less than 30 seconds,and consciousness recovered rapidly.Among the cases,3 exhibited hypermotor seizures of typeⅠorⅡ,characterized by body turning along the horizontal body axis.Two of them experienced laughter during the seizures,while 1 showed a fearful expression.The remaining 2 cases presented with symmetric tonic seizures,involving the facial muscles.One case reported indescribable aura,and 2 cases had autonomic symptoms.During the interictal period,all 5 cases showed epileptic discharges predominantly in the frontal region on EEG,with lateralization value present in only 2 cases.During the ictal period,4 cases demonstrated general low volatility and fast activity(LVFA),while 1 case showed low-frequency rhythmic sharp and slow waves originating from the lesioned side.Four cases underwent SEEG,which revealed seizure starting from the frontal operculum and adjacent electrodes with LVFA,rapidly spreading to the insula,insular opercular,and medial frontal lobe.Positive changes were observed in the MRI of 4 cases,including 2 cases with possible cortical dysplasia,1 case with tuberous sclerosis,and 1 case with encephalomalacia foci.All 4 cases underwent SEEG guided radiofrequency thermocoagulation,resulting in seizure frequency reduction.Conclusions Frontal opercular epilepsy is mainly characterized by hypermotor seizure with body turning along the horizontal body axis or symmetric tonic seizure.These seizure may be accompanied by emotional symptom or facial muscle tonic,but aura and autonomic symptom are less common.The lateralization value of EEG is limited in frontal opercular epilepsy.SEEG indicates early involvement of the insula,insular opercular,and medial frontal lobe.
