Background::Intrauterine growth restriction (IUGR) is associated with adverse metabolic outcomes during adulthood. Histone modifications and changes in DNA methylation-affected genes are important for fetal development. This study aimed to investigate the epigenetic mechanisms in IUGR.Methods::IUGR models were established in Sprague–Dawley rats using a maternal nutritional restriction approach during pregnancy. The abundance of insulin-like growth factor 2 (IGF2), phosphoinositide 3-kinase (PI3K), AKT serine/threonine kinase 2 (AKT2), and peroxisome proliferators-activated receptor gamma coactivator 1 alpha (PGC-1α) was examined by real-time polymerase chain reaction (RT-PCR) and Western blotting analysis. Chromatin immunoprecipitation RT-PCR was employed to analyze histone modification in CCCTC-binding factor (CTCF) 1–4 binding sites of the Igf2/H19 imprinting control region (ICR). The methylation states of CTCF1–4 binding sites were studied by pyrosequencing. Results::The IUGR models were constructed successfully. Igf2 mRNA abundance in the placenta, fetal liver, and newborn liver was decreased in the IUGR group ( P <0.01). Meanwhile, as compared with the control group, the expression levels of AKT2, PI3K, and PGC-1α were lower in newborn and 8-week-old livers in the IUGR group ( P <0.05). In addition, knocking down Igf2 reduced the protein expression levels of AKT2-phosphorylation and PGC-1α ( P <0.05). In CTCF binding sites 1-4 of the Igf2/ H19 ICR, acetylated histones H3 (AcH3) enrichment was significantly lower in CTCF1-3 in newborn and 8-week-old IUGR rats. Histone H3 tri-methylated lysine 4 (H3K4me3) enrichment was significantly lower in the CTCF1–4 of newborn and 8-week-old IUGR groups ( P <0.01). H3K9me2 enrichment was significantly higher in the IUGR group ( P <0.01). The CpG dinucleotide methylation levels of CTCF1 and CTCF3, but not those of CTCF2 and CTCF4 binding sites in IUGR rat fetal, 4-week old, and 8-week-old livers decreased significantly ( P <0.05). Conclusion::The methylation status and histone modification in the Igf2/H19 ICR are related to growth and lipid metabolism via the PGC-1α/PI3K/AKT2 pathway in IUGR rats.

OBJECTIVE:
To analyze the phenotype and genotype of a family with hereditary coagulation factor Ⅹ (FⅩ) deficiency and preliminarily explore its molecular pathogenesis.
METHODS:
A hereditary FⅩ deficiency pedigree presented at the First Affiliated Hospital of Wenzhou Medical University on August 13, 2024 was selected as the study subject. Coagulation parameters of the proband and her family members (7 individuals from 3 generations) were measured using a one-stage clotting assay. All of the 8 exons and flanking sequences of the F10 gene were amplified by PCR and directly sequenced. Bioinformatics software was used to analyze the functional impact and pathogenicity of the variant proteins, as well as the spatial conformational changes and evolutionary conservation of the mutation sites. This study has been approved by the Medical Ethics Committee of the First Affiliated Hospital of Wenzhou Medical University (Ethics No.: KY2022-R193).
RESULTS:
The proband exhibited significantly abnormal prothrombin time (PT, 33.3 s), activated partial thromboplastin time (APTT, 47.7 s), and FⅩ activity (FⅩ:C, 3%), while other coagulation parameters remained normal. The plasma thromboplastin generation test (PTGT) demonstrated that the proband and her children had lower thromboplastin generation levels compared with the healthy control group, and the proband's thromboplastin generation capacity was more severely impaired. Genetic analysis revealed that the proband, her daughter, and grandson have all harbored a heterozygous missense variant c.212T>C (p.Phe71Ser) in exon 2 of the F10 gene, which was located in the β-sheet core region of the Gla domain. The variant has altered surrounding hydrogen bonds and disrupted calcium-binding sites. Additionally, the proband, her son, and granddaughter have all carried a heterozygous missense variant c.1270G>T (p.Val424Phe) in exon 8, which increased the side-chain volume, leading to steric hindrance in the catalytic domain and impaired coagulation function. Bioinformatics analysis confirmed that both p.Phe71Ser and p.Val424Phe were pathogenic variants, with Phe71 and Val424 being highly conserved residues.
CONCLUSION
The reduced FⅩ levels in this hereditary FⅩ-deficient family may be attributed to the heterozygous missense variants c.212T>C (p.Phe71Ser) in the exon 2 and c.1270G>T (p.Val424Phe) in the exon 8 of the F10 gene.

Objective:
To investigate the effect of neurite outgrowth inhibitor extracellular peptide residues 1-40 (NEP1-40) combined with poly (lactic-co-glycolic acid) (PLGA) and gelatin electrospun fiber membrane on facial nerve repair in rats.
Methods:
According to the principle of random grouping, 108 male SD rats were divided into four groups (n = 27 in each group, approved by the ethics committee), namely, the sham group, control group, PLGA group, and NEP1-40 + PLGA group. A facial nerve fracture model was established for all of the groups except for the sham group. The control group received no further treatment, the PLGA group and the NEP1-40+PLGA group were supported by PLGA membrane, and the NEP1-40+PLGA group received one immediate local injection of NEP1-40 (5 μg/μL) at a dose of 10 μL. Facial nerve function analysis, electrophysiological examination, transmission electron microscope observation, HE staining, and immunohistochemical staining of myelin marker S100β and axonal marker β3-tubulin were used to evaluate the recovery of injured facial nerves of rats at 2, 4 and 8 weeks.
Results :
At 8 weeks, the facial nerve function score of the NEP1-40+PLGA group was better than that of the control group and PLGA group (P < 0.001), and facial nerve function was significantly restored. Electrophysiological examination of nerve action potentials at the injured facial nerve showed that the amplitude in the NEP1-40+PLGA group was higher than that of the control group and PLGA group (P < 0.001), but there was no significant difference in latency and conduction velocity results between the groups (P > 0.05). At 2, 4, and 8 weeks, transmission electron microscopy showed that the number of myelinated nerve fibers and myelin sheath thickness in the cross-section of the injured facial nerve in the NEP1-40+PLGA group were greater than those in the other groups (P < 0.05). At 8 weeks, HE staining showed that the facial nerves in the control group had partially recovered, but the overall cell distribution was uneven and the boundary with surrounding tissues was slightly blurred. In contrast, the NEP1-40+PLGA group had a relatively uniform cell distribution and a clearer boundary with surrounding tissues. At 2, 4, and 8 weeks, the immunohistochemical results showed that in the cross-section of the injuried facial nerve, NEP1-40 increased the expression of neural markers S100 β and β3-tubulin, especially β3-tubulin, which was close to normal levels (P > 0.05)
Conclusion
NEP1-40 is beneficial for the generation of new myelin sheaths and axons at the site of injury, and it can promote the repair and regeneration of injured facial nerves to a certain extent, thus accelerating the recovery of injured nerve function.

Mycophenolic acid (MPA), the active moiety of both mycophenolate mofetil (MMF) and enteric-coated mycophenolate sodium (EC-MPS), serves as a primary immunosuppressant for maintaining solid organ transplants. Therapeutic drug monitoring (TDM) enhances treatment outcomes through tailored approaches. This study aimed to develop an evidence-based guideline for MPA TDM, facilitating its rational application in clinical settings. The guideline plan was drawn from the Institute of Medicine and World Health Organization (WHO) guidelines. Using the Delphi method, clinical questions and outcome indicators were generated. Systematic reviews, Grading of Recommendations Assessment, Development, and Evaluation (GRADE) evidence quality evaluations, expert opinions, and patient values guided evidence-based suggestions for the guideline. External reviews further refined the recommendations. The guideline for the TDM of MPA (IPGRP-2020CN099) consists of four sections and 16 recommendations encompassing target populations, monitoring strategies, dosage regimens, and influencing factors. High-risk populations, timing of TDM, area under the curve (AUC) versus trough concentration (C0), target concentration ranges, monitoring frequency, and analytical methods are addressed. Formulation-specific recommendations, initial dosage regimens, populations with unique considerations, pharmacokinetic-informed dosing, body weight factors, pharmacogenetics, and drug-drug interactions are covered. The evidence-based guideline offers a comprehensive recommendation for solid organ transplant recipients undergoing MPA therapy, promoting standardization of MPA TDM, and enhancing treatment efficacy and safety.

OBJECTIVES:
To explore the relationship between the Observer's Assessment of Alertness/Sedation (OAAS) score and the bispectral index (BIS) during propofol titration for general anesthesia induction and analyze the impact of BIS monitoring delay on anesthetic depth assessment.
METHODS:
This study was conducted among 90 patients (ASA class I-II) undergoing elective surgery under general anesthesia. For anesthesia induction, the patients received propofol titration at the rate of 0.5 mg·kg-1·min-1 till OAAS scores of 4, 3, 2, and 1 were reached. After achieving an OAAS score of 1, remifentanil (2 μg·kg⁻¹) and rocuronium (0.6 mg·kg⁻¹) were administered, and tracheal intubation was performed 2 min later. BIS values, mean arterial pressure (MAP), heart rate (HR), and propofol dosage at each OAAS score were recorded, and the correlation between OAAS scores and BIS values was analyzed. The diagnostic performance of BIS values for determining when the OAAS score reaches 1 was analyzed using ROC curve.
RESULTS:
All the patients successfully completed tracheal intubation. BIS values of the patients at each of the OAAS scores differed significantly (P<0.01), and the mean BIS value decreased by 4.08, 8.32, 5.43 and 5.24 as the OAAS score decreased from 5 to 4, from 4 to 3, from 3 to 2, and from 2 to 1, respectively. There was a significant correlation between the OAAS score and BIS values (ρ=0.775, P<0.001). The median BIS value for an OAAS score of 1 was 76, at which point 83.33% of the patients had BIS values exceeding 60. ROC curve analysis showed that for determining an OAAS score of 1, BIS value, at the optimal cutoff value of 84, had a sensitivity of 88.9%, a specificity of 73.3%, and an area under the curve of 0.842 (0.803-0.881).
CONCLUSIONS
OAAS score during induction of general anesthesia is strongly correlated with BIS value and is a highly sensitive and timely indicator to compensate for the delay in BIS monitoring.

Pulpotomy, which belongs to vital pulp therapy, has become a strategy for managing pulpitis in recent decades. This minimally invasive treatment reflects the recognition of preserving healthy dental pulp and optimizing long-term patient-centered outcomes. Pulpotomy is categorized into partial pulpotomy (PP), the removal of a partial segment of the coronal pulp tissue, and full pulpotomy (FP), the removal of whole coronal pulp, which is followed by applying the biomaterials onto the remaining pulp tissue and ultimately restoring the tooth. Procedural decisions for the amount of pulp tissue removal or retention depend on the diagnostic of pulp vitality, the overall treatment plan, the patient's general health status, and pulp inflammation reassessment during operation. This statement represents the consensus of an expert committee convened by the Society of Cariology and Endodontics, Chinese Stomatological Association. It addresses the current evidence to support the application of pulpotomy as a potential alternative to root canal treatment (RCT) on mature permanent teeth with pulpitis from a biological basis, the development of capping biomaterial, and the diagnostic considerations to evidence-based medicine. This expert statement intends to provide a clinical protocol of pulpotomy, which facilitates practitioners in choosing the optimal procedure and increasing their confidence in this rapidly evolving field.
