Objective To explore the effects of CYP2C19, CYP2C9 and CYP3A5 genotypes on the plasma concentration of voriconazole in children. Methods Collected blood samples from 50 hospitalized children with invasive fungal infections who received intravenous voriconazole from January 2020 to December 2020. High performance liquid chromatography was used to detect the blood trough concentration of voriconazole, and the time-of-flight mass spectrometry detection system was used to detect the genotypes of CYP2C19, CYP2C9 and CYP3A5, and the effects of children’s genotyping on the plasma concentration, efficacy and adverse reactions of voriconazole were analyzed. Results The total effective rate of 50 children with IFI was 84% (42/50 cases) after voriconazole treatment. The incidence of adverse reactions was 20% (10/50 cases). The measured plasma concentration of voriconazole ranged from 0.56~7.62 μg/ml. Combined with the different mutation types of CYP2C19 gene loci, three metabolic activities were produced: fast, medium and slow, and the test results showed that there were 16 cases of fast metabolism, 27 cases of intermediate metabolism and 7 cases of slow metabolism. There was a significant difference in plasma concentrations among the three groups (F=15.359, P<0.001), and the drug concentrations in the fast metabolic group were significantly lower than those in the intermediate metabolic and slow metabolic groups. The mutations of CYP2C9 and CYP3A5 had no significant effect on the plasma concentrations of the drugs, which were (F=2.213, P=0.086 and F=0.757, P=0.475). Conclusion Voriconazole had significant efficacy in the treatment of invasive fungal infections in children, and the adverse reactions were mild. CYP2C19 genotype was significantly related to the rate of drug metabolism and was an important factor affecting blood drug concentration, the detection of drug concentration and genotype of voriconazole was helpful to adjust the effective drug dose clinically and would achieve more scientific and individualized treatment.

Autoimmune hepatitis (AIH) is an immune-mediated chronic liver inflammatory disease with unknown pathogenesis, and intestinal barrier dysfunction is considered an important factor. Meanwhile, there are sex and age differences in the incidence rate of AIH, suggesting that hormone may be involved in regulation. On this basis, this article focuses on the association between estrogen, intestinal barrier, and immune homeostasis, systematically reviews the evidence that estrogen deficiency disrupts intestinal barrier homeostasis, and further summarizes the potential mechanism of estrogen in regulating the development and progression of AIH via intestinal barrier.

Bombesin receptor subtype-3 (BRS3) is an orphan G protein-coupled receptor (GPCR) that plays critical roles in energy homeostasis, glucose metabolism, and insulin secretion. Recent structural studies have elucidated BRS3 signaling mechanisms using synthetic ligands, including BA1 and MK-5046. However, the molecular basis of BRS3 activation by bioactive natural compounds and their derivatives, particularly those derived from traditional Chinese medicine, remains unclear. Here, we present high-resolution cryogenic electron microscopy (cryo-EM) structures of the human BRS3-Gq complex in both unliganded and active states bound by two herb-derived compounds (DSO-5a and oridonin), at resolutions of 2.9, 2.8, and 2.9 Å, respectively. These structures display distinct ligand recognition patterns between DSO-5a and oridonin. Although both compounds bind to the orthosteric pocket, they differentially engage the interaction network of BRS3, as demonstrated by mutagenesis studies assessing calcium mobilization and inositol phosphate 1 (IP1) accumulation. These findings enhance our understanding of BRS3 activation and provide valuable insights into the development of small-molecule BRS3 modulators with therapeutic potential.

Acute lateral ankle sprain (ALAS) is one of the most common sport injuries, with high incidence, recurrence and disability rates. Currently, exercise rehabilitation-based non-surgical treatment is the primary management approach for ALAS. However, there remain improper practices such as excessive immobilization or uncontrolled activity, which contribute to recurrent sprains and chronic ankle instability, significantly impairing patients′ athletic function and quality of life. To standardize the non-surgical management of ALAS, improve the cure rates, and reduce the recurrence and disability rates, Chinese Sports Rehabilitation Medicine Training Project of Chinese Medical Association, Foot and Ankle Basics and Orthopedics Group, Orthopedic Branch of Chinese Medical Doctor Association, and Sports Medicine Branch of Jiangsu Medical Association organized relevant experts to formulate Expert consensus on non-surgical treatment for acute lateral ankle sprain ( version 2025), following the principles of scientific vigor, practicality, and innovation. Thirteen recommendations were proposed for standardized treatment protocols across different healing phases, aiming to provide references for standard management of ALAS and improve the therapeutic outcomes.

Large inter-individual and intra-individual differences in the expression and activity of drug-metabolizing enzymes(DMEs)contribute to unpredictable drug response and toxicity,which is a challenge facing precision medicine.Nuclear receptor-mediated transcriptional regulation and epigenetic mechanisms including histone modifications,non-coding RNAs,and DNA methylation can help to explain the individual variability in DME expressions.However,several questions remain unanswered.Recently,epitranscriptomics,an emerging field,provides new insights into the regulation of gene expression.As the most abundant RNA modification in eukaryotes,N6-methyladenosine(m6A)modifi-cation plays key roles in various physiological and pathological processes.This review summarizes the recent progress in m6A modification-mediated individual variability in DME expression in terms of the role of m6A modification in regulating basal expression of DMEs,crosstalk between m6A modification and nuclear receptors during the ontogeny of DMEs,and the contribution of m6A modification to xenobi-otic exposure-mediated changes in DME expression.This review aims to provide data for the elucida-tion of individual variations in drug metabolism in clinic.
8.Advances in the Application of Repetitive Transcranial Magnetic Stimulation for Acute and Maintenance Treatment of Major Depressive Disorder
Medical Journal of Peking Union Medical College Hospital 2025;16(2):321-329
Major depressive disorder (MDD) is a prevalent psychiatric condition characterized by high rates of prevalence and recurrence. Repetitive transcranial magnetic stimulation (rTMS) has been widely utilized in the acute phase treatment of MDD and has shown potential in maintenance therapy. However, the factors influencing the efficacy of rTMS during the acute phase and the sustainability of its long-term therapeutic effects remain incompletely understood. Additionally, a consensus on the optimal maintenance treatment protocol has yet to be established. This article reviews recent evidence on the application of rTMS in both acute and maintenance treatment of MDD, aiming to summarize current research progress and provide insights for the further promotion and application of rTMS in clinical practice.

ObjectiveTo investigate the protective effects and mechanisms of Bushen Zhuyun prescription (BSZY) on abortion rats with kidney deficiency-corpus luteum inhibition syndrome. MethodsAn abortion rat model with kidney deficiency-corpus luteum inhibition syndrome was constructed. Pregnant mice aged 8-10 weeks were randomly divided into a control group (Control), a model group (Model), low-dose BSZY (BSZY-L), medium-dose BSZY (BSZY-M), and high-dose BSZY (BSZY-H) groups (2.57, 5.14, 10.28 g·kg-¹), and a Zishen Yutai Pill (ZSYT) group (1.575 g·kg-¹). Hematoxylin-eosin (HE) staining was used to evaluate histopathological changes in ovarian and decidual tissue of rats in each group. Enzyme-linked immunosorbent assay (ELISA) was employed to measure levels of estrogen (E₂), progesterone (P), luteinizing hormone (LH), prolactin (PRL), and follicle-stimulating hormone (FSH) in serum. The candidate targets of BSZY were obtained from the Traditional Chinese Medicine System Pharmacology Platform (TCMSP) and Integrative Pharmacology-based Research Platform of Traditional Chinese Medicine (TCMIP) v2.0 databases, while disease targets for recurrent spontaneous abortion (RSA) were retrieved from GeneCards, DrugBank, Online Mendelian Inheritance in Man (OMIM), and Therapeutic Target Database (TTD). The intersection targets were identified by the Venny 2.1.0 platform. Pathway enrichment analysis was conducted based on the Metascape database to predict the potential mechanisms of BSZY. Additionally. Western blot was used to verify the effects of BSZY on the expression of estrogen receptor (ERα), phosphatidylinositol 3-kinase (PI3K), and protein kinase B (Akt) and explore its protective mechanism on RSA rats. ResultsCompared with the control group, the model group exhibited significantly decreased uterine, ovarian, and embryonic wet weights (P<0.05, P<0.01), with an abortion rate of 57.18%. The ovarian tissue showed varying degrees of reduction in primordial follicles, primary follicles, mature follicles, and corpora lutea, along with a large number of atretic follicles. The endometrium was thinner, and decidual tissue exhibited cellular edema and disorganized arrangement. In contrast, compared with the model group, the BSZY groups at all doses and the ZSYT group demonstrated increased uterine, ovarian, and embryonic wet weights, along with a reduced abortion rate. The number of primordial follicles, primary follicles, mature follicles, and corpora lutea increased, while atretic follicles decreased. The endometrium thickened, and decidual tissue displayed normal cellular structure with tight arrangement. Additionally, the model group showed significantly decreased levels of E₂, P, PRL, and FSH in serum (P<0.05, P<0.01), along with a decreasing trend in LH level. In contrast, the BSZY groups at all doses exhibited significantly elevated levels of E₂, P, LH, PRL, and FSH in serum (P<0.05, P<0.01). Network pharmacology predictions suggested that BSZY may exert protective effects against abortion in rats by activating the ERα/PI3K/Akt signaling pathway. Western blot results confirmed that BSZY significantly upregulated the expression of ERα, PI3K, and p-Akt proteins (P<0.05, P<0.01). ConclusionBSZY has a protective effect on the abortion rats with kidney deficiency-corpus luteum inhibition syndrome, possibly by activating the ERα/PI3K/Akt signaling pathway to reduce ovarian apoptosis and regulate endocrine function, thereby lowering the abortion rate.

Objective To investigate the cardiac protective effect of Taohong Tongluo granules on coronary microvascular dysfunction(CMD)rats.Methods SD rats were randomly assigned to sham-operated group,CMD group,nicorandil group(5 mg/kg),or Taohong Tongluo granule group(50 mg/kg).Animals were administered corresponding drugs for 7 d according to the grouping,and the CMD model was prepared 2 h after the last administration.The rat CMD model was induced by injecting embolization microspheres(diameter 40-120 μm,approximately 1 000 microspheres)into the left ventricular cavity.Twenty-four hours after modeling,echocardiography was performed to measure the left ventricular ejection fraction(EF),fractional shortening(FS),and end-diastolic volume(EDV).The damaged myocardial area was assessed by 2,3,5-triphenyltetrazolium chloride(TTC)staining.Myocardial morphological changes were observed by hematoxylin-eosin(H-E)staining.The protein expression levels of NOD-like receptor family pyrin domain containing protein 3(NLRP3),apoptosis-associated speck-like protein(ASC),and cysteine aspartic acid specific protease(caspase)-1 in rat myocardial tissue were detected by immunohistochemical staining and Western blotting.Results Echocardiography showed that the EF and FS values in the Taohong Tongluo granule group,CMD group,and nicorandil group were significantly lower than those in the sham-operated group(all P<0.001).The EF and FS values in the Taohong Tongluo granule group and nicorandil group were significantly higher than those in the CMD group(all P<0.01).However,there were no significant differences in EDV among the groups(all P>0.05).H-E staining showed no abnormalities in the myocardium in the sham-operated group.The CMD group exhibited microsphere embolism in the myocardium,myocardial cell dissolution and rupture,and inflammatory infiltration.The lesions in the nicorandil group and the Taohong Tongluo granule group were relatively milder,and the number of thrombi in both groups was lower than that in the CMD group(both P<0.01).The results of TTC staining indicated that the areas of damaged myocardial regions in both the nicorandil group and the Taohong Tongluo granule group were smaller than that in the CMD group(P<0.05 or P<0.01).Moreover,the area in the Taohong Tongluo granule group was smaller than that in the nicorandil group(P<0.05).The results of immunohistochemical staining showed that in the CMD model,the expression of ASC and caspase-1 proteins,as well as the number of positive cells for these proteins,was increased and was distributed in myocardial and interstitial cells.The numbers of ASC and caspase-1 positive cells in the Taohong Tongluo granule group were lower than that in the CMD group(both P<0.01).The Western blotting showed that the expression levels of NLRP3,ASC,and caspase-1 proteins in the Taohong Tongluo granule group were all lower than those in the CMD group(all P<0.05).Conclusion Taohong Tongluo granules can improve cardiac function,ameliorate hemodynamic parameters,and reduce myocardial infarction area in rats with CMD induced by microsphere embolism.The mechanism is related to the inhibition of myocardial inflammasome activation,thereby attenuating the myocardial injuries.
