【Objective】 To explore the application value of different language assessment tools in the assessment of language development of 12-month-old high-risk infants, and to screen out simple and valid language assessment tools. 【Methods】 A total of 217 11- to 13-month-old high-risk infants who were followed up at the outpatient service for high-risk infants at the child health clinic of Guiyang Maternal and Child Health Hospital from March 2022 to May 2023 were selected as the study subjects. Their language was evaluated by Early Language Milestone Scale (ELMS), Putonghua Communicative Development Inventory (PCDI) and Ages and Stages Questionnaire-Third Edition (ASQ-3). With Gesell as the gold standard for the assessment of language, the area under receiver operating characteristic curve (AUC), sensitivity, specificity, accuracy, positive predictive value, negative predictive value, Youden index and Kappa value of the three tools were calculated. Spearman correlation analysis was used to analyze the correlation between the different language assessment scales. The Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) was used to evaluate the three tools. 【Results】 1)Among 217 high-risk infants, 78 preterm infants was the most (35.94%). The rate of delayed language development detected by Gesell, ELMS, PCDI-comprehension, PCDI-expression, ASQ-3 were 5.5%, 7.8%, 36.4%, 30.0% and 11.5%, respectively. 2)ASQ-3 had the strongest correlation with Gesell language region (rs=0.607, P<0.01) and it had the most AUC (AUC=0.812, P<0.05). The consistency between ASQ-3 and Gesell was moderate (Kappa=0.56, P<0.01). ASQ-3 had the highest sensitivity(91.7%), accuracy(93.1%), negative predictive value(99.5%) and Youden index(0.85), and ELMS had the highest specificity(94.6%). 3) Comprehensive evaluation of three tools by the TOPSIS indicated that ASQ-3 was the best, followed by ELMS and PCDI-comprehension was the worse. 【Conclusion】 Among the three assessment tools, ASQ-3 has the highest value in assessing the language development of 11- to 13-month-old high risk infants, and it may be necessary to expand the age range and establish a national norm of ELMS and PCDI in the future.

Chimeric antigen receptor (CAR)-T cell therapy has achieved remarkable success in the treatment of hematological malignancies. Based on the immunomodulatory capability of CAR-T cells, efforts have turned toward exploring their potential in treating autoimmune diseases. Bibliometric analysis of 210 records from 128 academic journals published by 372 institutions in 40 countries/regions indicates a growing number of publications on CAR-T therapy for autoimmune diseases, covering a range of subtypes such as systemic lupus erythematosus, multiple sclerosis, among others. CAR-T therapy holds promise in mitigating several shortcomings, including the indiscriminate suppression of the immune system by traditional immunosuppressants, and non-sustaining therapeutic levels of monoclonal antibodies due to inherent pharmacokinetic constraints. By persisting and proliferating in vivo, CAR-T cells can offer a tailored and precise therapeutics. This paper reviewed preclinical experiments and clinical trials involving CAR-T and CAR-related therapies in various autoimmune diseases, incorporating innovations well-studied in the field of hematological tumors, aiming to explore a safe and effective therapeutic option for relapsed/refractory autoimmune diseases.

Objective:To evaluate the efficacy of SedLine Brain Function Monitor-guided total intravenous anesthesia for children undergoing hypospadias surgery.Methods:This was a randomized controlled trial. A total of 161 children, aged 1-10 yr, with American Society of Anesthesiologists Physical Status classification ⅠorⅡ, scheduled for elective hypospadias surgery, were divided into SedLine group (S group, n=83) and control group (C group, n=78) using a random number table method. In group S, 95% spectral edge frequency (SEF 95) was maintained at 14-18 Hz, and the patient state index (PSI) was maintained at 25-50 during surgery. In group C, mean arterial pressure was maintained at 60-80 mmHg, and heart rate was maintained at 80-110 beats/min during surgery. PSI and SEF 95 were recorded before induction (T 1), at 0, 5 and 10 min after intubation (T 2-4), at the beginning of surgery (T 5), at 30 min and 1 h after surgery (T 6, 7), and at the end of surgery (T 8). The anesthetic duration, operation time, time from withdrawal to extubation, postanesthesia care unit duration, consumption of propofol and remifentanil, intraoperative adverse events, 5-point Likert scale scores, and emergence delirium scores were recorded. Results:Compared to C group, the total anesthesia time, time from withdrawal to extubation and postanesthesia care unit duration were significantly shortened, the consumption of propofol for both induction and maintenance was reduced, the PSI at T 5-8, SEFL 95 at T 2-6, and SEFR 95 at T 2-8 were increased, and the incidence of intraoperative body movement and incidence of emergence agitation were decreased in S group ( P<0.05). Conclusions:SedLine Brain Function Monitor-guided total intravenous anesthesia provides better efficacy when used for the children undergoing hypospadias surgery.

Objective To investigate the correlation between serum levels of brain natriuretic peptide (BNP), cancer antigen 125 (CA125) and interleukin-6 (IL-6) with the severity of acute myocardial infarction (AMI) and to evaluate their predictive value for major adverse cardiovascular events (MACE) after percutaneous coronary intervention (PCI). Methods A total of 100 AMI patients who underwent PCI were enrolled in this study. Patients were divided into MACE group (n=36) and non-MACE group (n=64) based on the occurrence of MACE. Clinical data and serum levels of BNP, CA125 and IL-6 were compared between the two groups. The correlations of serum BNP, CA125 and IL-6 levels with the severity of AMI were analyzed. Factors influencing the occurrence of MACE after PCI in AMI patients were examined. Receiver operating characteristic (ROC) curves were used to assess the predictive value of serum BNP, CA125 and IL-6 for MACE after PCI. Conventional predictive scheme combined risk factors served as the conventional prediction model, while a new prediction model was developed by incorporating serum BNP, CA125 and IL-6 into the conventional model. The area under the curve (AUC), net reclassification improvement (NRI) and integrated discrimination improvement (IDI) were used to compare the predictive values of the two models. Results Among the 100 AMI patients, 36 experienced MACE within three months after PCI. The MACE group had significantly higher age, white blood cell (WBC) count, prevalence of prior myocardial infarction and severity of AMI compared to the non-MACE group (P < 0.05). Serum levels of BNP, CA125 and IL-6 were significantly higher in the MACE group than in the non-MACE group (P < 0.05). Serum BNP, CA125 and IL-6 levels were positively correlated with the severity of AMI (r=0.513, 0.406, 0.320; P < 0.05). Age, WBC count, history of myocardial infarction, and serum BNP, CA125 as well as IL-6 were identified as significant predictors for MACE after PCI (P < 0.05). The AUC for the combined prediction for MACE using BNP, CA125 and IL-6 was greater than that of each individual marker (Z=2.134, 2.005, 2.087; P < 0.05). When age, WBC count and history of myocardial infarction were combined as the conventional prediction model, and serum BNP, CA125 and IL-6 were added to form the new prediction model, the AUC of the new model was significantly higher than that of the conventional model (Z=2.321, P < 0.05). Compared with the conventional prediction scheme, the new prediction scheme had both NRI and IDI greater than zero P < 0.05). Conclusion Elevated serum levels of BNP, CA125 and IL-6 in AMI patients are associated with the severity of AMI and have predictive value for MACE after PCI. The new prediction model with BNP, CA125 and IL-6 demonstrates superior predictive performance for MACE after PCI compared to the conventional model.

Remdesivir-loaded liposomes for inhalation were prepared and the in vitro properties were evaluated. Firstly, preparation methods of remdesivir-loaded liposomes were screened, and single-factor experiments were conducted to optimize the prescription and preparation process. Then the physical property, deposition ratio and aerodynamic particle size distribution of remdesivir-loaded liposomes suspension for inhalation were comprehensively evaluated. As a result, the optimal liposomes were prepared by the thin-film dispersion method with pH 6.5 phosphate-buffered saline as the hydration medium. In the prescription, the ratio of drug to DPPC was 1∶20; the cholesterol accounted for 10% of total lipids; and 20% DSPE-mPEG 2000 was added as stabilizer.4% trehalose was added as lyoprotectant when lyophilizing to obtain ideal appearance, good stability and a small particle size change after reconstitution. Remdesivir-loaded liposomes were spherical with smooth surface and uniform particle size distribution under transmission electron microscope. In vitro release tests showed no significant change for release curves of remdesivir-loaded liposomes suspension before and after nebulization. Deposition experiments indicated that the fine particles fraction of liposomes was 51.4%, and the mass median aerodynamic diameter was less than 5 μm measured by next generation impactor. To sum up, remdesivir-loaded liposomes for inhalation with high encapsulation efficiency and stability can achieve a suitable particle size distribution to effectively deposit in the lung after nebulization, which provides a new approach for the treatment of COVID-19.
