This study aims to explore whether Guzheng playing training has a positive impact on the brain functional state of children with Autism Spectrum Disorder (ASD) based on power spectral and sample entropy analyses. Eight ASD participants were selected to undergo four months of Guzheng playing training, with one month as a training cycle. Electroencephalogram (EEG) signals and behavioral data were collected for comparative analysis. The results showed that after Guzheng playing training, the relative power of the alpha band in the occipital lobe of ASD children increased, and the relative power of the theta band in the parietal lobe decreased. The differences compared with typically developing (TD) children were narrowed. Moreover, some channels exhibited a gradual increase or decrease in power with the extended training period. Meanwhile, the sample entropy parameter also showed a similar upward trend, which was consistent with the behavioral data representation. The study shows that Guzheng training can enhance the brain function of ASD patients, with better effects from longer training. Guzheng playing training could be used as a daily intervention for autism.

OBJECTIVE To explore the practicality of the pharmaceutical pathway for prophylactic use of antibiotics during the perioperative period of class Ⅰ neurosurgery incisions. METHODS The previously established pharmaceutical pathway for the prophylactic use of antibiotics in the perioperative period of class Ⅰ neurosurgery incisions was used to retrospectively evaluate the prophylactic use of antibiotics in 127 cases. The “antibiotics prophylactic use scoring system” in the pharmaceutical pathway was used to conduct preoperative scoring， and the patient’s actual antibiotics use was compared and analyzed in combination with existing Guiding Principles for Clinical Application of Antibiotics （2015 Edition） （hereinafter referred to as the Guiding Principles）. The pharmaceutical pathway also innovatively proposes key points for improvement in terms of the frequency of adding antibiotics during surgery and the duration of prophylactic use of antibiotics after surgery. By comparing with the actual medication situation of patients， the direction for updating the Guiding Principles was explored. RESULTS According to the retrospective analysis results， for neurosurgery class Ⅰ incision surgery， in addition to the preoperative prophylactic use of antibacterial drugs for skull mass resection and carotid endarterectomy recommended in the guidelines， endoscopic trigeminal microvascular decompression， arthroscopy and other specific joint examinations， spinal nerve Radical decompression， endoscopic lumbar nucleectomy， dural repair， and spinal canal decompression can also be further explored about the situation of not using antibacterial prophylaxis before surgery； at the same time， for the patients undergoing class Ⅰ neurosurgery incisions， the use of antibiotics during and after surgery may be considered for a second addition of antibiotics， taking into account the surgical time. If cerebrospinal fluid leakage occurred after surgery， it is recommended to extend the duration of prophylactic use of antibiotics appropriately. CONCLUSIONS The application of pharmaceutical pathways can provide more targeted analysis of key points in the prevention of antibiotic use， which promotes the transformation of perioperative antibiotics management for class Ⅰ incisions from “qualitative， empirical” management to “quantitative， scientific” management.

With the implementation of the Healthy China Strategy, the value of care has become increasingly prominent. It has become an important nursing topic to strengthen the theoretical and practical research of nurse-patient communication, especially to understand the current state, and explore the essential characteristics, the influencing factors and the differences in interdisciplinary perspectives of nurse-patient communication. Through systematic analysis of 100 real clinical nurse-patient communication cases, this paper found that the problem of poor nurse-patient communication still existed widely, which is prominently manifested as the inhibition of communication willingness, the dislocation of communication topics and the lack of communication consensus. The causes of poor nurse-patient communication were nurses’ poor communication skills, negative emotional distress, the lack of humanistic literacy and insufficient energy investment in communication, as well as the patient’s fragile state, the limitation of knowledge and cultural level, and insufficient trust in nurses. The interdisciplinary perspective analysis of ethics, psychology and law is conducive to enriching and developing the theoretical basis and research methods of nurse-patient communication, and can also provide useful suggestions for improving nurse-patient communication in clinical.

Objective To systematically evaluate the efficacy of β-blocker in pediatric patients with congestive heart failure and congenital heart disease,and to provide evidence for clinician.Methods Before-and-after self-control study and randomized controlled trials were retrieved from PubMed,EMbase,the Cochrane Library,CNKI,WanFang,VIP databases,and the search time was from the establishment of the database to October 31,2023.All outcomes included left ventricular ejection fraction(LVEF),left ventricular fraction shortening,LVFS),left ventricular end-diastolic dimension(LVDD),Left ventricular end-systolic dimension(LVSD),N-terminal proB brain natriuretic peptide(NT-proBNP),heart rate,blood pressure and cardiac function improvement.Results A total of 20 trials involving 1 068 children with heart failure(dilated cardiomyopathy and endocardial fibroelastosis were included.Meta-analysis results showed that the addition of β-blockers(metoprolol succinate,bisoprolol and carvedilol)on the basis of conventional drug therapy for heart failure had significant effects on LVEF[MD=13.06,95%CI(11.67,14.45),P<0.001],LVFS[MD=6.96,95%CI(6.54,7.37),P<0.001],LVDD[MD=-6.43,95%CI(-7.58,-5.28),P<0.001]and LVSD[MD=-8.30,95%CI(-8.83,-7.76),P<0.001]were significantly improved.In addition,blood pressure,heart rate,NT-proBNP and cardiac function could also be improved.Conclusion The combination regimen of β-blockers on the basis of conventional drug therapy for heart failure can improve cardiac function and symptoms of heart failure in children with congestive heart failure.Therefore,it is recommended that β-blockers should be actively used in the conventional treatment regimen for children with congestive heart failure.

Objective To assess inter-observer variations(IOV)in the delineation of target volumes and organs-at-risk(OAR)for intensity-modulated radiotherapy(IMRT)of nasopharyngeal carcinoma(NPC)among physicians from different levels of cancer centers,thereby providing a reference for quality control in multi-center clinical trials.Methods Twelve patients with NPC of different TMN stages were randomly selected.Three physicians from the same municipal cancer center manually delineated the target volume(GTVnx)and OAR for each patient.The manually modified and confirmed target volume(GTVnx)and OAR delineation structures by radiotherapy experts from the regional cancer center were used as the standard delineation.The absolute volume difference ratio(△V_diff),maximum/minimum volume ratio(MMR),coefficient of variation(CV),and Dice similarity coefficient(DSC)were used to compare the differences in organ delineation among physicians from different levels of cancer centers and among the 3 physicians from the same municipal cancer center.Furthermore,the IOV of GTVnx and OAR among physicians from different levels cancer centers were compared across different TMN stages.Results Significant differences in the delineation of GTVnx were observed among physicians from different levels of cancer centers.Among the 3 physicians,the maximum values of △V_diff,MMR,and CV were 97.23%±83.45%,2.19±0.75,and 0.31±0.14,respectively,with an average DSC of less than 0.7.Additionally,there were considerable differences in the delineation of small-volume OAR such as the left and right optic nerves,chiasm,and pituitary,with average MMR>2.8,CV>0.37,and DSC<0.51.However,relatively smaller differences were observed in the delineation of large-volume OAR such as the brainstem,spinal cord,left and right eyeballs,and left and right mandible,with average△V_diff<42%,MMR<1.55,and DSC>0.7.Compared with the differences among physicians from different levels cancer centers,the differences among the 3 physicians from the municipal cancer center were slightly reduced.Furthermore,there were also differences in the delineation of target volumes for NPC among physicians from different levels cancer centers,depending on the staging of the disease.Compared with the delineation of target volumes for earlier stage patients(stages I or II),the differences among physicians in the delineation of target volumes for advanced stage patients(stages III or IV)were smaller,with average △V_diff and DSC of 98.31%±67.36%vs 69.38%±72.61%(P<0.05)and 0.55±0.08 vs 0.72±0.12(P<0.05),respectively.Conclusion There are differences in the delineation of GTVnx and OAR in radiation therapy for NPC among physicians from different levels of cancer centers,especially in the delineation of target volume(GTVnx)and small-volume OAR for early-stage patients.To ensure the accuracy of multicenter clinical trials,it is recommended to provide unified training to physicians from different levels of cancer centers and review their delineation results to reduce the effect of differences on treatment outcomes.

Objective:To develop a prediction model using machine learning to identify anxiety and depression in elderly individuals.Methods:This study collected data from 15079 elderly individuals in Shanxi Province, including their social demographic factors and disease status.Anxiety and depression were evaluated using GAD-7 and PHQ-9 scales to understand the characteristics of mental illness in the elderly.The evaluation indexes included accuracy, recall, precision, F1 score, Receiver Operating Characteristic Curve(ROC), and area under the curve(AUC), which were derived from the confusion matrix and several models.Results:The output of our study clearly demonstrates that the full feature prediction based on LightGBM is highly accurate, with an AUC of 0.805[95% CI: 0.794-0.811]. This outperforms the Random Forest model, which achieved an AUC of 0.730[95% CI: 0.702-0.741], and the XGboost model, which achieved an AUC of 0.802[95% CI: 0.780-0.807]. Therefore, LightGBM algorithm proves to be a strong prediction model.Our simplified model, based on eight selected features, also achieves a respectable AUC of approximately 0.75. Conclusions:The new prediction model for anxiety and depression specifically designed for the elderly can be effectively utilized in grassroots health surveys or for self-examinations to efficiently predict anxiety and depression levels among the elderly population in the community.

Objective To investigate the current status,evolving hotspots,and emerging trends in the field of human re-source allocation research in public hospitals,both domestically and internationally,to provide a reference for future research di-rections in China.Methods CiteSpace was used to conduct a visual analysis of the research literature on human resource alloca-tion in public hospitals based on China National Knowledge Infrastructure(CNKI)and the Web of Science(WOS).The analysis encompassed co-authorship,institutional collaboration,keyword co-occurrence and clustering,and burst detection.Results A total of 1 417 Chinese articles and 981 international articles were included.Domestic research in this field focused more on healthcare reform and management,resource allocation,hierarchical diagnosis,and treatment,and informatization and efficiency improvement.On the contrary,international research primarily centered on the employee satisfaction,healthcare system quality,work environment and medical staff.Future trends in domestic research included cost reduction,efficiency enhancement,and a greater emphasis on public welfare in public hospitals,while international research was beginning to explore the influence of polit-ical concepts in this field.Conclusion Compared to international research,domestic research needs to further improve its theo-retical and localized understanding,broaden its research scope,explore the interdisciplinary collaboration opportunities,and delve into research directions such as the application of artificial intelligence and automation technology in healthcare services,management of a diverse workforce,and innovative management techniques and applications.

The leukocyte immunoglobulin-like receptor LILRB4(ILT3 or CD85k),a member of the immunosuppressive re-ceptor family,is expressed predominantly on the cell membranes of immune cells of myeloid origin,and exerts an immunosuppressive effect in immune regulation by activating either the autoinhibitory motif(ITIM)or by inhibiting Fc receptor activation motif(ITAM).In tumors,activation of LILRB4 receptor generates an immunosuppressive tumor microenvironment that assists in tumor invasion and metastasis,and in inflammatory diseases,LILRB4 is expressed on a variety of cells,such as monocytes,macrophages,mast cells,etc.,and attenuates inflammatory responses.Currently,LILRB4 has become a therapeutic target for tumors and various inflammatory diseases,and anti-LILRB4 monoclonal antibodies against acute myeloid leukemia(AML)have entered clinical trials.This review dis-cusses LILRB4 in terms of its structural distribution,signaling,therapeutic targets,and new drug development.

Objective:To analyze the clinical, genetic mutation characteristics, and treatment prognosis of type 2A hereditary hemochromatosis (HH) in China.Methods:Peripheral blood samples and clinical data of patients with primary iron overload were collected through the China Registry of Genetic/Metabolic Liver Disease from June 2015 to November 2023. HH-related genes were detected by Sanger sequencing. Clinical characteristics and gene mutation characteristics of HH patients carrying HJV gene mutations were analyzed.Results:Among the 37 cases with primary iron overload, ten cases (27.0%, 10/37) had detectable HJV gene mutations, which included four homozygous mutations, five compound heterozygous mutations, and one monoheterozygous mutation. p.Q6H and p.C321X (80.0%, 8/10) were the most common mutated sites. The average age of onset was 30.7±14.7 years. The age of diagnosis was 35.7±16.2 years, with male-to-female ratio of 7:3. Ferritin and transferrin saturation were (5 267±905) ng/ml, and 94.3%±1.2%, respectively. Magnetic resonance imaging showed iron overload in the liver, pancreas, and myocardium. Liver biopsy showed diffuse iron deposition within hepatocytes. All ten cases had elevated transaminases; one case (1/10, 10.0%) had liver cirrhosis; four cases (4/10, 40.0%) had heart failure and arrhythmia; five cases (5/10, 50.0%) had diabetes; six cases (6/10, 60.0%) had hypogonadism; six cases (6/10, 60.0%) had skin pigmentation; and six cases (6/10, 60.0%) had fatigue symptoms. All six cases underwent bloodletting therapy, and ferritin levels dropped to about 100 ng/ml. Two cases of oral administration of the iron chelator deferasirox did not meet the ferritin level standard, and one case died from acute heart failure following a confirmed diagnosis during hospitalization.Conclusion:The HJV gene may be one of the main pathogenic genes of HH in China. The p.Q6H and p.C321X mutations were one of the hotspot mutations. The onset age of HJV gene-related HH was between 20 and 30 years old, and their condition was severe. Therefore, early bloodletting treatment can have a favorable outcome.
