A UHPLC-Q-Orbitrap/MS method was developed to identify the related substances in apixaban tablets. Complete separation was accomplished with a Waters Xbridge C18 (250 mm×4.6 mm, 5 μm) column by linear gradient elution using a mobile phase consisting of 30 mmol/L ammonium acetate buffer solution (pH 4.50) and acetonitrile. The related substances were successfully characterized through the accurate mass and elemental composition of the parent ions and their product ions determined by electrospray positive ionization high-resolution Q-Orbitrap/MS methods. Under the established analytical condition, apixaban and its related substances were well separated, and 30 related substances were detected and identified by hyphenated techniques in apixaban tablets and their stressed samples. Among them, 11 were known impurities and the rest 19 were unknown related substances identified for the first time in this study. The results obtained are valuable for apixaban manufacturing process optimization and quality control.

BACKGROUND:
The hepatitis B virus (HBV) vaccine has been efficiently used for decades. However, hepatocellular carcinoma caused by HBV is still prevalent globally. We previously reported that interferon (IFN)-induced tripartite motif-containing 25 (TRIM25) inhibited HBV replication by increasing the IFN expression, and this study aimed to further clarify the anti-HBV mechanism of TRIM25.
METHODS:
The TRIM25-mediated degradation of hepatitis B virus X (HBx) protein was determined by detecting the expression of HBx in TRIM25-overexpressed or knocked-out HepG2 or HepG2-NTCP cells via Western blotting. Co-immunoprecipitation was performed to confirm the interaction between TRIM25 and HBx, and colocalization of TRIM25 and HBx was identified via immunofluorescence; HBV e-antigen and HBV surface antigen were qualified by using an enzyme-linked immunosorbent assay (ELISA) kit from Kehua Biotech. TRIM25 mRNA, pregenomic RNA (pgRNA), and HBV DNA were detected by quantitative real-time polymerase chain reaction. The retinoic acid-inducible gene I (RIG-I) and pgRNA interaction was verified by RNA-binding protein immunoprecipitation assay.
RESULTS:
We found that TRIM25 promoted HBx degradation, and confirmed that TRIM25 could enhance the K90-site ubiquitination of HBx as well as promote HBx degradation by the proteasome pathway. Interestingly, apart from the Really Interesting New Gene (RING) domain, the SPRY domain of TRIM25 was also indispensable for HBx degradation. In addition, we found that the expression of TRIM25 increased the recognition of HBV pgRNA by interacting with RIG-I, which further increased the IFN production, and SPRY, but not the RING domain is critical in this process.
CONCLUSIONS
The study found that TRIM25 interacted with HBx and promoted HBx-K90-site ubiquitination, which led to HBx degradation. On the other hand, TRIM25 may function as an adaptor, which enhanced the recognition of pgRNA by RIG-I, thereby further promoting IFN production. Our study can contribute to a better understanding of host-virus interaction.

Objective:
To explore the relationship between adolescent depressive symptoms, childhood psychological trauma and maternal illness during pregnancy, so as to provide scientific busis for the development of adolescent mental health.
Methods:
A stratified cluster random sampling method was employed to select 2 092 primary and secondary school students in Wuhan City from January to July 2022. Questionnaires were administered to investigate adolescent depressive symptoms, childhood psychological trauma, and maternal illness during pregnancy. The influencing factors of adolescent depression were analyzed.
Results:
A total of 139 adolescents reported depressive symptoms. The childhood trauma questionnaire (CTQ) score of the depression group was (57.49± 6.85 ), and the score in adolescents without depression group was (46.28±5.96)( t =21.14, P <0.05). Among the maternal diseases during pregnancy, hypertension accounted for 11.51% , diabetes 9.35%, cholestasis 7.19%, hypothyroidism/hyperthyroidism 7.91% , anemia 9.35% and viral hepatitis 3.60% in depression group, 5.79%, 4.71%, 3.64%, 3.07%, 4.30%, 1.18% in the group without depression, respectively, and the differences were statistically significant ( χ 2=7.35, 5.87, 4.42, 9.28, 7.49, 5.75, P <0.05). The proportion of academic stress in the depressed group and non-depressed group were 61.15% and 46.34%, respectively, and was statistically significant ( χ 2=16.04, P <0.05). Multivariate Logistic regression analysis showed that gestational hypertension ( OR=5.04, 95%CI =2.07-12.24), diabetes mellitus ( OR=4.49, 95%CI =1.85-10.91), anemia ( OR=3.68, 95%CI =1.51-8.94), high academic stress ( OR=3.52, 95%CI =1.45-8.56) and the Childhood Trauma Questionnaire ( OR=4.63, 95%CI = 1.91 -11.26) were the risk factors of depression in adolescents ( P <0.05).
Conclusion
Adolescent depression may be due to high academic stress, childhood psychological trauma, maternal hypertension, diabetes, thyroid dysfunction and anemia in pregnancy. It is suggested that relevant departments provide appropriate measures to reduce the risk of adolescent depression.

Women with gestational hyperglycemia tend to encounter breastfeeding difficulties, which may lead to breastfeeding failure or short duration of breastfeeding. Antenatal breastmilk expression, stimulating or massaging the breasts during pregnancy to produce milk and to collect and store colostrum, is beneficial to lactogenesis, thereby reducing formula feeding, promoting the transition to exclusive breastfeeding and increasing the exclusive breastfeeding rate. This review summarizes the safety and feasibility of antenatal breastmilk expression for women with gestational hyperglycemia, aiming to provide breastfeeding guidance for this population.
