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.

Immunotherapy has become a pivotal modality in clinical cancer treatment. However, its effectiveness is limited to a small subset of patients due to the low antigenicity, impaired innate response, and various adaptive immune resistance mechanisms of the tumor microenvironment (TME). Accumulating evidence reveals the critical roles of metal elements in shaping immunity against tumor progression and metastasis. The marriage of metalloimmunotherapy and nanotechnology further presents new opportunities to optimize the physicochemical and pharmacokinetic properties of metal ions in a precise spatiotemporal control manner. Several metallodrugs have demonstrated encouraging immunotherapeutic potential in preliminary studies and are currently undergoing clinical trials at different stages, yet challenges persist in scaling up production and addressing long-term biosafety concerns. This review delineates how metal materials modulate biological activities across diverse cell types to orchestrate antitumor immunity. Moreover, it summarizes recent progress in smart drug delivery-release systems integrating metal elements, either as cargo or vehicles, to enhance antitumor immune responses. Finally, the review introduces current clinical applications of nanomedicines in metalloimmunotherapy and discusses potential challenges that impede its widespread translation into clinical practice.

The theory of fetal metabolic programming indicates that an adverse developmental environment during the mother's pregnancy can significantly increase the risk of chronic metabolic diseases such as obesity,diabetes mellitus and cardiovascular diseases in the offspring in adulthood.Exercise during pregnancy can effectively improve and even reverse the disorders of glycolipid metabolism in offspring caused by poor nutritional environment during pregnancy.The placenta serves as a crucial interface facilitating the exchange of substances and signal molecules between mother and baby,and also plays an important role in mediating fetal metabolic programming and early life intervention.This article reviews the regulatory role of placental function in maternal motion-mediated fetal metabolic programming.

OBJECTIVE: To explore the clinical phenotype and genetic characteristics of a child with Progressive familial intrahepatic cholestasis type 8 (PFIC8). METHODS A child with PFIC diagnosed at Beijing Children's Hospital Affiliated to Capital Medical University in September 2025 was selected as the study subject. Peripheral venous blood samples were collected from the child and her parents. Following extraction of genomic DNA, whole-exome sequencing (WES) was carried out. Candidate variants were validated by Sanger sequencing. The pathogenicity of the candidate variants was classified based on the guidelines from American College of Medical Genetics and Genomics (ACMG). This study was approved by the Medical Ethics Committee of Beijing Children's Hospital Affiliated to Capital Medical University (Ethics No.: 2023-E-126-Y). RESULTS: The proband, a 2-month-old female infant, had manifested jaundice of the skin and sclera, and slightly distended abdomen. She had no visible abdominal wall varicose veins, soft abdomen, and no palpable masses. Biliary atresia was ruled out by intraoperative cholangiography. WES revealed that she has harbored compound heterozygous variants of KIF12 gene, namely c.809C>T (p.Ala270Val) and c.1313G>A (p.Arg438Lys), which were verified by Sanger sequencing to have derived from her mother and father, respectively. According to the ACMG guidelines, both variants were classified as variants of uncertain significance (VUS). Based on the pre-defined search strategy, 10 articles were retrieved, which involved 25 PFIC cases, including 5 from China. Together with the proband of this study, the 26 PFIC patients have primarily presented with high GGT cholestasis, with the genetic cause in all cases attributed to variants of the KIF12 gene. CONCLUSION The c.809C>T and c.1313G>A compound heterozygous variants of the KIF12 gene probably underlay the pathogenesis of cholestatic liver disease in this child. Above findings have enriched the mutational and phenotypic spectra of PFIC8.

ObjectivesTo summarize the clinical and pathological features of patients with congenital liver fibrosis （CHF）， and to investigate the differences in clinical and pathological features between patients in different age groups. MethodsA retrospective analysis was performed for the clinicopathological data of 26 patients with pathologically confirmed CHF in China-Japan Friendship Hospital from August 2005 to June 2023， and the patients were stratified by age to investigate the clinical and pathological features of patients in different age groups. ResultsAmong the 26 patients， there were 12 male patients and 14 female patients， with an age of onset of 4 — 61 years. There were 19 patients with portal hypertension type （73.08%）， 2 patients with cholangitis type （7.69%）， 4 patients with mixed type （15.38%）， and 1 patient with occult type （3.85%）. Of all 26 patients， 4 had unknown clinical symptoms， and among the 22 patients with clear clinical symptoms， 10 （45.45%） attended the hospital due to upper gastrointestinal bleeding caused by portal hypertension. Pathological manifestations included roughly normal liver parenchyma separated by fibrous septa in the portal area， with the presence of abnormal reactive bile duct hyperplasia. Denser fibrous septa and a lack of portal veins with the corresponding caliber were observed in 4 pediatric patients with disease onset before the age of 10 years， with a significant reduction or even disappearance of compensatory thin-walled blood vessels. ConclusionPortal hypertension-type CHF is the most common type in clinical practice. Patients with an early age of onset have certain histopathological features of the liver， with the presence of serious complications associated with portal hypertension. Therefore， liver biopsy should be performed for patients suspected of CHF in clinical practice， and genetic testing should be performed when necessary. Early identification and diagnosis are of great importance for improving the prognosis of patients.

AIM:The purpose of this paper is to study whether the precise administration of vanco-mycin under the guidance of the model can achieve better clinical treatment effect by imple-menting the precise medication model in Sichuan Provincial People's Hospital,so as to promote its wide application in practice.METHODS:A prospec-tive cohort study was conducted.The experimental group was patients who used the Model-informed Precision Dosing to determine the vancomycin dos-ing regimen,and the control group was patients who only decided the vancomycin dosing regimen based on the existing diagnosis and treatment pro-cess.Two sets of data were matched to compare whether there were significant differences be-tween the two groups of patients in the TDM steady-state trough concentration or the steady-state AUC compliance ratio,and to evaluate the ap-plication value of the model software.RESULTS:Ac-cording to the inclusion and exclusion criteria,the steady-state blood concentration data of vancomy-cin in a total of 280 patients were used for analysis.The final result of the experiment was that the number of people in the experimental group was 10,and the compliance rate was 62.50％.There were 64 cases in the control group,and the compli-ance rate was 24.24％(P=0.002).CONCLUSION:The study found that the model-guided precise dos-ing regimen can more accurately control the blood concentration of vancomycin in patients,and signif-icantly improve the patient's steady-state trough concentration compliance rate.Therefore,it is rec-ommended to increase the research on the pro-gram and promote its wide application in clinical practice.

Objective To explore the influence of different bone quality around the implant on the implantation accuracy,the com-puter-aided design of implant guide plate was used for patients with poor bone quality to evaluate its accuracy.Methods Retrospective analysis of relevant clinical data from 29 single-tooth implant patients with relatively poor bone quality meeting inclusion criteria was conducted.Using 3Shape Implant Studio software,implant plans were designed and fully guided digital templates were fabricated before surgery.Implantation was guided by the templates throughout,with torque and ISQ values recorded to evaluate the initial stability of the implant.Postoperative implant positions were reconstructed using CBCT images,and the three-dimensional deviation of implant place-ment was evaluated in conjunction with the preoperative design.Bone quality around the implants was also recorded and analyzed before and after surgery.Results In this study,digital guide plates were used in patients with poor bone quality,and the initial stability of implants was≥20 N·cm except for three cases.In cases of poor bone quality,the accuracy of the fully guided digital templates was as follows:cervix deviation(0.94±0.59)mm,apex deviation(1.40±0.81)mm and angle deviation 4.10°±2.99°.Bone quality had a greater impact on angle deviation(P＜0.05).The higher the proportion of D3 bone was around the implant body 1/3,the smaller the deviation of neck,apex and angle was,while the higher the proportion of D5 bone,the greater the deviation of implantation.Conclu-sion For patients with poor bone quality,under the premise of restoration-oriented,the proportion of D3 bone around the implant can be increased by computer-aided design,and the initial stability of the implant can be improved by guiding the implantation with digital guide plate.Attention should be paid to the influence of bone on the angle deviation of implant during the application of guide plate.

Lung cancer is the leading type of cancer death, and most patients with lung cancer are diagnosed at an advanced stage and have a very poor prognosis. Although low-dose computed tomography (LDCT) has entered the clinic as a screening tool for lung cancer, its false-positive rate is more than 90%. As one of the epigenetic modifications of research hotspots, DNA methylation plays a key role in a variety of diseases, including cancer.Hypermethylation of tumor suppressor genes and hypomethylation of proto-oncogenes are important events in tumorigenesis and development. Therefore, DNA methylation analysis can provide some useful information for the early screening, diagnosis, treatment and prognosis of lung cancer. Although invasive methods such as tissue biopsy remain the gold standard for tumor diagnosis and monitoring, they also have limitations such as inconvenience in sampling. In recent years, there has been a rapid development of liquid biopsy, which can detect primary or metastatic malignancies and reflect the heterogeneity of tumors. In addition, the blood sample can be collected in a minimally invasive or non-invasive format and is well tolerated in older and frail patients. This article explores some of the emerging technologies for DNA methylation analysis and provides an overview of the application of DNA methylation in the diagnosis and treatment of lung cancer.
