ObjectiveTo investigate the mechanism of salt processing of Psoraleae Fructus （PF） through modern analytical techniques and biotechnology， focusing on its effects related to hepatotoxicity and anti-osteoporosis activity. MethodsThe zebrafish model was utilized to evaluate the impact of PF and salt-processed Psoraleae Fructus （SPF） on the hepatotoxicity （using 134.17 ， 178.89， 268.34 mg·L^-1 as low， medium， and high dose groups of PF， 135.04， 180.06， 270.08 mg·L^-1 as low， medium， and high dose groups of SPF， respectively） and anti-osteoporotic activity （using 33.54 ， 67.08 and 134.17 mg·L^-1 as low， medium， and high dose groups of PF， 33.76， 67.52， 135.04 mg·L^-1 as low， medium， and high dose groups of SPF， respectively）， which was using alizarin red skull staining of zebrafish as an indicator of different batches of PF. The specific dosage of a batch of PF was taken as an example. Then ultra-performance liquid chromatography-quadrupole-time of flight-mass spectrometry（UPLC-Q-TOF-MS） analysis was employed to identify the chemical composition of PF before and after salt processing， and PCA， OPLS-DA， and independent sample t-test were used to elucidating the compositional changes associated with the effects of salt processing on hepatotoxicity and anti-osteoporosis activity. ResultsUnder specific conditions， PF induced notable hepatotoxicity in zebrafish while simultaneously demonstrating protective effect against prednisolone-induced osteoporosis. In comparison to PF， SPF showed alleviated hepatotoxicity while retaining significant anti-osteoporosis activity. UPLC-Q-TOF-MS analysis revealed that after salt processing， the overall chemical composition of PF showed a downward trend， with 69 components showing a decrease in content， represented by psoralen， and 13 components showing an increase， represented by 4′-O-methyl psoralen B. Further multivariate statistical analysis revealed 11 key differential components before and after salt processing of PF， including psoralen and bakuchiol. ConclusionSalt processing effectively diminishes hepatotoxicity without impairing therapeutic efficacy against osteoporosis of PF， which may be related to the compositional changes before and after salt processing of PF and provides key evidence to reveal the scientific significance of salt processing of PF.

In modern society， the comorbidity of insomnia with amnesia has shown a significantly increasing incidence and become increasingly severe， emerging as a public health issue that endangers people's physical and mental health and quality of life. Anmei Dan （AMD）， originally recorded in the Shishi Milu by CHEN Shiduo in the Qing Dynasty， possesses profound theoretical foundations and distinct clinical advantages in ameliorating insomnia with amnesia. Basic research has unequivocally confirmed its definite therapeutic effects on insomnia with amnesia and revealed partial mechanisms. AMD is therefore a veritable classic prescription embodying the principle of treating different diseases with the same method for insomnia and amnesia. However， few researchers have reviewed the related research progress. This article systematically summarized the theoretical connotations of traditional Chinese medicine in treating insomnia with amnesia， delineated the multi-component material basis of AMD in ameliorating insomnia with amnesia （including various chemical components such as ginsenosides， jujubosides， and salvianolic acids）， and evaluate its multi-dimensional clinical efficacy （e.g.， prolonging total sleep time， improving sleep efficiency， and enhancing memory）. Moreover， it systematically summarizes the multi-pathway mechanisms of action. The results indicate that AMD has a clear material basis， definite clinical efficacy， and a favorable safety profile in ameliorating insomnia and amnesia. AMD may exert the therapeutic effect by regulating sleep-wake rhythms， enhancing synaptic plasticity， inhibiting neuroimmune inflammation， and modulating autophagy， oxidative stress， and energy metabolism. In conclusion， AMD exerts synergistic effects through multi-component， multi-dimensional， and multi-pathway approaches， serving as an important prescription for enriching and developing the theory of treating different diseases with the same method for insomnia with amnesia.

Objective:To investigate the clinical phenotype and genetic etiology of a patient with tall stature and primary amenorrhea presenting with 47, XYY Disorder of sex development (DSD).Methods:A female patient presenting with " tall stature and primary amenorrhea" at Nanjing Drum Tower Hospital in July 2024 was selected as the study subject. A retrospective study design was employed to collect the patient′s clinical data. Peripheral venous blood sample was collected. Following the extraction of genomic DNA, genetic testing was performed including chromosomal karyotyping analysis, copy number variation sequencing (CNV-seq), multiplex PCR for the AZF regions and sex-determining genes Y ( SRY), and whole-exome sequencing (WES). Candidate variants were validated by Sanger sequencing and classified for pathogenicity based on the guidelines from the American College of Medical Genetics and Genomics (ACMG). This study was approved by the Medical Ethics Committee of Nanjing Drum Tower Hospital (Ethics No.: 2022-451-01). Results:The patient had a height of 188 cm and a body weight of 50 kg, in addition with infantile uterus, absent ovaries, and primary amenorrhea. G-banded karyotyping analysis of peripheral blood sample revealed 47, XYY. CNV-seq indicated Seq[GRCh37]Yp11.32q12×2. No deletion was detected in the AZF regions of Y chromosome, and SRY was positive. WES identified a heterozygous c. 86C>A (p.Thr29Lys) variant of the NR5A1 gene, leading to substitution of threonine with lysine at position 29 of the encoded protein. Sanger sequencing confirmed the presence of the variant. According to the ACMG guidelines, this variant was classified as variant of uncertain significance (VUS) with supporting evidence (PS3_Moderate+ PM5+ PP3+ PM2_Supporting+ PS4_Supporting). Reviewing the nearly 60 years of previously reported cases, all 7 documented 47, XYY DSD patients were assigned a female social gender and presented with abnormal gonadal and external genitalia development. Among them, 5 cases underwent SRY testing, all of which were positive. Only 1 case underwent whole-exome sequencing (WES), but no pathogenic or likely pathogenic variants were identified. Conclusion:This DSD patient presented with the clinical features of tall stature and primary amenorrhea. The NR5A1 gene variant c. 86C>A (p.Thr29Lys) probably underlay the disorder of sex development in this patient. Above finding has enriched the spectrum of pathogenic variants of the NR5A1 gene.

Tooth development is a complex biomineralization process formed through the interaction between epithelial tissue and mesenchymal tissue. The Ca 2+ transport channel is the intrinsic regulatory mechanism of this process, which regulates the concentration of Ca 2+ inside and outside the cell in time and space, thereby affecting the biological functions of various cells and the growth of extracellular hydroxyapatite. This article reviews the researches on the effects of Ca 2+ transport in tooth biomineralization and corresponding cell development in recent years, with the aim of providing ideas and basis for the prevention of tooth developmental defects, assisting in early clinical diagnosis, and improving treatment methods.

Objective:To investigate the clinical characteristics and risk factors associated with secondary systemic capillary leak syndrome (SSCLS) induced by acute organophosphorus pesticide poisoning (AOPP). The goal is to enhance clinical understanding of this complication and provide a theoretical foundation for the early identification of high-risk patients and the optimization of individualized treatment strategies.Methods:Clinical data were collected from patients admitted to the Emergency Department of Fuyang People’s Hospital Affiliated to Anhui Medical University between October 2019 and October 2024, who were diagnosed with acute dichlorvos poisoning. The clinical features of SSCLS were described, and patients were categorized into SSCLS and non-SSCLS groups. Binary multivariate logistic regression analysis was conducted on statistically significant indicators to identify independent risk factors for SSCLS. Receiver operating characteristic (ROC) curves were generated to evaluate the predictive value of these factors.Results:Among the 96 patients studied, 37 (38.5%) developed SSCLS. The median time from toxin ingestion to the onset of SSCLS was 3.0 (2.0-5.0) hours. In the 14 SSCLS survivors, the median duration of SSCLS was 50.0 (24-72) hours, whereas in the 23 non-survivors, it was 24.0 (12.0-35.0) hours. The mortality rate in the SSCLS group (62.16%, 23/37) was significantly higher than that in the non-SSCLS group (1.69%, 1/59) ( χ2=44.343, P<0.001). Blood toxin analysis detected trichlorfon components in 92 patients (95.83%). Binary multivariate logistic regression identified APACHE Ⅱ score and trichlorfon concentration (≥706.35 ng/mL) as independent risk factors for SSCLS ( P<0.05). ROC analysis revealed that the combination of these two factors had a higher predictive value ( P<0.05). Conclusions:In the diagnosis and treatment of acute dichlorvos (organophosphorus pesticide) poisoning, particular attention should be given to the combined toxic effects of dichlorvos and trichlorfon, which can lead to SSCLS. The onset and progression of SSCLS are rapid, and the condition is associated with a high mortality rate. Both APACHE Ⅱ scores and trichlorfon concentrations (≥706.35 ng/mL) are independent risk factors for the development of SSCLS, and their combined use enhances predictive accuracy. Early identification of high-risk patients and timely administration of individualized treatment are critical for reducing mortality rates. This revised abstract maintains the original meaning while improving clarity, flow, and readability. It ensures that the key points are presented in a structured and professional manner, suitable for a clinical audience.
