OBJECTIVE To evaluate the clinical efficacy of Chaihu anxin capsules in the treatment of mild-to-moderate depression， analyze the influencing factors of its efficacy, construct a nomogram prediction model.METHODS Patients with mild-to-moderate depression treated at The First Hospital of Hebei Medical University from May 1， 2023 to March 10， 2025 were retrospectively included and categorized into Chaihu anxin capsules group and milnacipran group according to treatment regimen. Propensity score matching （PSM） was used to balance baseline characteristics， and treatment efficacy was compared after 8 weeks， including 24 Hamilton Depression Scale （HAMD-24） scores and changes， Hamilton Anxiety Scale （HAMA） scores and changes， and treatment response rate after 8 weeks of treatment. Patients receiving Chaihu anxin capsules were further classified as responders or non-responders based on the occurrence of treatment response. Univariate and multivariate Logistic regression analyses were conducted to identify the influencing factors of treatment response， and a nomogram model was constructed to predict the probability of treatment response， its predictive performance was evaluated using receiver operating characteristic （ROC） curves， calibration curves， and decision curve analysis.RESULTS A total of 297 patients were included before PSM， including 196 patients in the Chaihu anxin capsules group and 101 patients in the milnacipran group. After PSM， each group included 44 patients. After PSM， the HAMD-24 scores and HAMA scores at 8 weeks after treatment in the Chaihu anxin capsules group， as well as the HAMD-24 scores in the milnacipran group， were significantly lower than their respective baseline values （ P ＜0.05）； the change in HAMA score in the Chaihu anxin capsules group was significantly greater than that in the milnacipran group （ P ＝0.04）. Multivariable Logistic regression identified age， total bilirubin， and baseline HAMD-24 score as independent predictors of treatment response （ P ＜0.05）. The area under the ROC curve of the constructed nomogram prediction model was 0.72 （95% confidence interval： 0.637-0.799）， and the corrected Brier score was 0.143 （95% confidence interval： 0.112-0.176）； compared with the “all intervention” and “all non intervention” strategies， applying this nomogram prediction model could achieve higher net benefits within the threshold probability range of 8% to 37%.CONCLUSIONS The efficacy of Chaihu anxin capsules in improving mild-to-moderate depression is comparable to that of milnacipran， and it has certain advantages in improving anxiety symptoms； age， total bilirubin， and baseline HAMD-24 score are independent influencing factors for the treatment response of Chaihu anxin capsules. The nomogram prediction model constructed based on these factors has good discrimination， calibration， and clinical applicability.

Objective:To investigate the impact of metformin on the Beh?et's disease (BD) mice model via the Treg/Th17 axis.Methods:The BD mice model was established by subcutaneous injection of HSV-1. Four groups were established, including healthy control group, model group, high-dose metformin group, and low-dose metformin group. The HSV-1 DNA copy number in the peripheral blood was measured using qRT-PCR. Plasma levels of TGF-β 1, IL-10, IL-17, IL-23, IL-6, and TNF-α were assessed by ELISA. Flow cytometry was employed to determine the proportion of Treg and Th17 cells in the spleen. One-way analysis of variance was used for inter-group comparisons, pairwise comparisons were performed using SNK- q test. Results:Thirty-eight BD models were successfully established, with 28 survived. Compared to the BD model group, the metformin treatment groups showed faster healing of genital ulcers, joint redness/swelling, and skin ulcers, along with better mental status. HSV-1 copy numbers decreased in the metformin groups compared to the model group at 20 and 30 days post-treatment. Compared to the healthy control group, the model group exhibited elevated levels of TGF-β 1, IL-17, IL-6, IL-23, and TNF-α, but a decrease in IL-10. Following high-dose metformin treatment, TGF-β 1, IL-17, IL-6, IL-23, and TNF-α were significantly reduced ( q=16.17, P<0.001; q=8.76, P<0.001; q=6.78, P=0.004; q=4.45, P=0.020; q=12.08, P<0.001), accompanied by elevated IL-10 (specific value) ( q=6.28, P<0.001). Compared with the control group [Treg: (1.82±0.68)%; Th17: (2.12±0.86)%], the model group showed significantly elevated proportions of Treg cells[(6.03±2.42)%] ( q=5.01, P<0.001) and Th17 cell [(3.40±0.58)%] ( q=2.96, P=0.017). After high-dose metformin treatment, both Treg cell proportion [(3.20±1.66)%] and Th17 cell proportion [(2.16±0.78)%] decreased compared to the model group ( q=3.05, P=0.014). No significant differences were observed between the high-and low-dose metformin groups across all measured indicators, indicating similar efficacy. Conclusion:Metformin could reduce HSV-1 virus replication, reduce the levels of inflammatory cytokines and regulate Treg/Th17 axis to alleviate the BD symptoms. This study provides evidence for repurposing metformin in the treatment of Beh?et's disease.

Objective To explore the predictive value of heel blood thyrotropin stimulating hormone(TSH)and insulin-like growth factor-1(IGF-1)for congenital hypothyroidism(CH).Methods A total of 83 children with CH admitted to the Seventh Medical Center of the Chinese People's Liberation Army General Hospital from January 2021 to January 2024 were selected as the study group,and 53 healthy newborns born and examined in the center during the same period were selected as the control group.Heel blood TSH,IGF-1 and thyroid function were measured in both groups.Heel blood TSH,IGF-1 and thyroid function indexes were compared between the two groups,and the correlation between heel blood TSH,IGF-1 and thyroid function indexes was analyzed,the influencing factors of CH occurrence were analyzed,and the predictive value of heel blood TSH,IGF-1 and thyroid indexes for CH was analyzed.Results Pearson correlation analysis showed that heel blood TSH was negatively correlated with FT4,TT3,FT3 and TT4(r=-0.522,-0.468,-0.539,-0.667,all P＜0.05).IGF-1 was positively correlated with FT4,TT3,FT3,TT4(r=0.394,0.427,0.511,0.562,all P＜0.05).The results of receiver operating characteristic curve analysis showed that the area under the curve of TSH,IGF-1 and their combination were 0.800,0.794 and 0.822,respectively.Univariate and multiple Logistic regression analysis showed that birth weight,family history,TSH,IGF-1,FT4,FT3 were the influencing factors for the occurrence of CH(P＜0.05).Conclusion The combined detection of TSH and IGF-1 levels in heel blood has a certain predictive value for the occurrence of CH,and can provide a basis for the disease assessment of children.

Glioma represents the most prevalent malignant tumor of the central nervous system, with chemotherapy serving as an essential adjunctive treatment. However, most chemotherapeutic agents exhibit limited ability to penetrate the blood-brain barrier (BBB). This study introduced a novel dual-targeting strategy for glioma therapy by modulating the formation of nanobody-driven protein coronas to enhance the brain and tumor-targeting efficiency of hydrophobic cisplatin prodrug-loaded lipid nanoparticles (C8Pt-Ls). Specifically, nanobodies (Nbs) with fibrinogen-binding capabilities were conjugated to the surface of C8Pt-Ls, resulting in the generation of Nb-C8Pt-Ls. Within the bloodstream, Nb-C8Pt-Ls could bound more fibrinogen, forming the protein corona that specifically interacted with LRP-1, a receptor highly expressed on the BBB. This interaction enabled a "Hitchhiking Effect" mechanism, facilitating efficient trans-BBB transport and promoting effective brain targeting. Additionally, the protein corona interacted with LRP-1, which is also overexpressed in glioma cells, achieving precise tumor targeting. Computational simulations and SPR detection clarified the molecular interaction mechanism of the Nb-fibrinogen-(LRP-1) complex, confirming its binding specificity and stability. Our results demonstrated that this strategy significantly enhanced C8Pt accumulation in brain tissues and tumors, induced apoptosis in glioma cells, and improved therapeutic efficacy. This study provides a novel framework for glioma therapy and underscores the potential of protein corona modulation-based dual-targeting strategies in advancing treatments for brain tumors.

Nonalcoholic fatty liver disease(NAFLD)is the chronic liver disease with the highest global preva-lence.It has multiple causes and complex mechanisms,and its prevalence is increasing year by year.Currently,there are still no drugs that are widely promoted and used.Quercetin possesses multiple pharmacological activities such as antioxida-tion,anti-inflammation,lipid-lowering and regulation of intestinal flora.Recent studies have shown that it can intervene in the progression of NAFLD through multiple pathways,including anti-inflammation,promotion of autophagy,inhibition of oxidative stress,attenuation of insulin resistance,regulation of endoplasmic reticulum stress and improvement of cogni-tion.In addition,quercetin can also inhibit diabetes mellitus complicated with NAFLD lesions.This article reviews the mechanism by which quercetin alleviates NAFLD,with the aim of providing a reference for the clinical prevention and treatment of NAFLD.

UNLABELLED: OBJECTIVE：To explore the clinical characteristics and genetic etiology of a child with CAKUTHED syndrome. METHODS: A child who was admitted to the neonatal department of Gansu Provincial Maternal and Child Health Care Hospital due to "neonatal asphyxia" in May 2021 was selected as the study subject. Genomic DNA was extracted from peripheral venous blood samples from the child and his parents, and whole exome sequencing (WES) was carried out. Sanger sequencing was used to verify the candidate variant of the PBX1 gene. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the pathogenicity of candidate variants was rated. This study was approved by the Medical Ethics Committee of the Hospital [Ethics No.: 2021GSFY (65)]. RESULTS: The proband, a male neonate, manifested renal dysplasia, congenital heart disease, pulmonary dysplasia, mediastinal hernia, cryptorchidism, and clavicle dysplasia. WES revealed that he had harbored a heterozygous c.863G>A (p.Arg288Gln) missense variant in exon 6 of PBX1 gene, which resulted substitution of Arginine at position 288 by Glutamine, for which both parents were of the wild type. The variant was unreported previously and rated as pathogenic (PS2+PM1+PM2_Supporting+PP2+PP3) based on the ACMG guidelines. CONCLUSION The c.863G>A variant of the PBX1 gene probably underlay the pathogenesis in the proband. Above finding has enriched the mutational spectrum of the PBX1 gene.
