ObjectiveTo explore the relationship between negative life events and depression severity in adolescent patients with depressive disorder， as well as the chain mediating role of insomnia symptoms and quality of life. Methods374 outpatient patients and hospitalized patients with adolescent depressive disorders were enrolled. The Adolescent Life Event Scale （ASLEC）， the Insomnia Severity Index （ISI）， the World Health Organization Quality of Life Questionnaire Short Form （WHOQOL-BREF）， and the Center for Epidemiology Depression Scale （CES-D） were used to evaluate the negative life event situation， insomnia symptoms， quality of life level and depression severity of the subjects， respectively. In addition， the PROCESS 4.0 macroprogram was used to analyze the chain mediating effect of insomnia symptoms and quality of life between negative life events and depression severity in patients with adolescent depressive disorder. ResultsThe results of correlation analysis showed that there was a significant correlation between negative life events and insomnia symptoms， quality of life， and depression severity （all P<0.05）. In addition， the results of chain mediation showed that negative life events had a significant direct effect on depression severity， with an effect size of 0.12 （P<0.001）. Insomnia symptoms and quality of life played a mediating role in the relationship between negative life events and depression severity in patients with adolescent depressive disorders， with indirect effect sizes of 0.062 （95%CI： 0.040-0.087） and 0.091 （95%CI： 0.059-0.123）， respectively. It could also play a chain mediation role， and the effect size was 0.039 （95%CI： 0.024-0.057）. ConclusionNegative life events experienced by patients with adolescent depressive disorder not only directly affect the severity of depressive symptoms， but may also indirectly exacerbate depression through insomnia symptoms and quality of life.

In recent years, with the continuous development and increasing maturity of interventional techniques, interventional treatment for congenital heart disease (CHD) has been progressively disseminated to county- and city-level hospitals in China. Concurrently, the standardized management of adult CHD (particularly patent foramen ovale) and the lifelong management of complex CHD are gaining increasing clinical attention, while the emergence of new techniques and products continuously advances the discipline. This article aims to review the new progress made in the field of interventional treatment for congenital heart disease in China during 2024. It specifically reviews and analyzes the following key aspects: (1) annual statistics on interventional closure procedures for CHD; (2) recent insights into patent foramen ovale closure; (3) advances in transcatheter pulmonary valve replacement; (4) interventional treatment and lifelong management strategies for complex CHD; (5) new interventional techniques for acquired heart disease; and (6) the application of artificial intelligence in CHD management.

Objective:To compare the efficacy of neuroendoscopy-assisted small bone window craniotomy and large bone flap craniotomy for acute subdural hematoma (ASDH) evacuation in elderly patients.Methods:A retrospective cohort study was conducted to analyze the clinical data of 57 elderly patients with ASDH admitted to Chongqing University Fuling Hospital from November 2020 to November 2023, including 27 males and 30 females, aged 65-89 years [(75.0±7.0)years]. The preoperative Glasgow coma scale (GCS) ranged 8-15 points [11.0(11.0, 12.0)points]. Among them, 27 patients were treated with neuroendoscopy-assisted small bone window craniotomy to evacuate ASDH (small bone window group) and 30 received large bone flap craniotomy to evacuate ASDH (large bone flap group). The following parameters were compared between the two groups: surgical duration, intraoperative blood loss, and length of hospital stay; residual subdural hematoma volume before surgery and at 1 day after surgery; GCS before surgery, at 1 and 3 days after surgery; good rate of Glasgow outcome scale (GOS) at 7 days and 6 months after surgery; and postoperative complication rate.Results:All the patients were followed up for 6 months. The surgical duration, intraoperative blood loss, and length of hospital stay were 89.0(85.0, 96.0)minutes, 65.0(55.0, 85.0)ml, and 15.0(14.0, 16.0)days, respectively in the small bone window group, which were shorter or less than 135.0(127.5, 150.0)minutes, 332.0(308.0, 367.5)ml, and 18.5(16.0, 20.0)days in the large bone flap group ( P<0.01). There was no statistically significant difference in the residual subdural hematoma volume between the two groups before surgery and at 1 day after surgery ( P>0.05). No statistically significant difference was found in GCS scores between the two groups before surgery ( P>0.05), while the GCS scores in the small bone window group at 1 and 3 days after surgery [12.0(12.0, 13.0)points and 15.0(14.0, 15.0)points] were higher than 11.5(11.0, 12.0)points and 13.0(12.8, 14.0)points in the large bone flap group ( P<0.01). The good rate of GOS in the small bone window group at 7 days after surgery was 100% (27/27), higher than 77% (23/30) in the large bone flap group ( P<0.05), but no statistically significant difference was found in the good rate of GOS between the two groups at 6 months after surgery ( P>0.05). Two patients in the small bone window group had pulmonary infection after surgery, with a complication rate of 7% (2/27), while in the large bone flap group, four patients had pulmonary infection, two epidural hematoma, one intracranial infection, one delayed wound healing, one subcutaneous fluid accumulation, and one epilepsy after surgery, with a complication rate of 33% (10/30) ( P<0.05). Conclusion:Compared with the conventional large bone flap craniotomy, neuroendoscopy-assisted small bone window craniotomy can shorten the surgical duration and length of hospital stay, reduce the intraoperative bleeding volume, promote early functional recovery, improve prognosis, and reduce the complication rate in elderly patients with ASDH.

Objective To elucidate the correlation between specific nucleocapsid(N)protein mutant of the SARS-CoV-2 B.1.1.7 variant and clinical stratification in COVID-19 patients,revealing their impact on N protein liquid-liquid phase separation(LLPS)and host innate immune response.Methods Based on whole-genome sequencing data of the SARS-CoV-2 B.1.1.7 lineage from the GISAID database,non-synonymous mutation sites significantly associated with mild/severe clinical phenotypes were screened.For high-frequency N protein mutant,IFN-β promoter transcriptional activity was quantitatively measured using a dual-luciferase reporter system.qPCR was used to detect the mRNA expression levels of interferon(IFN)-β,interleukin(IL)-6 and tumor necrosis factor(TNF)-α.LLPS characteristics were observed by confocal microscopy.The ubiquitination status of host MAVS was detected by Western blot assay.Results A total of 17 640 non-synonymous mutation sites were identified,among which 65 were associated with mild cases and 20 were related to severe cases,with a mutation frequency>1%.The N protein mutation sites associated with severe cases were D3L,M234I and R203K-G204R-T205I.N protein and the mutants NM234I,NR203K-G204R-T205I inhibited the promoter activity of IFN-β(P＜0.05).Compared to the wild type N protein,NR203K-G204R-T205I mutation significantly reduced the mRNA levels of IFN-β,IL-6 and TNF-α(P＜0.05),and altered the phase separation state by dispersing the formation of LLPS condensates.However,N mutant did not affect the ubiquitination modification of host MAVS.Conclusion N protein mutants of the SARS-CoV-2 B.1.1.7 variant can influence the clinical prognosis of COVID-19 patients by altering LLPS status and suppressing the innate immune responses.These finding provides a theoretical basis for the design of antiviral drugs targeting the N protein.

This paper reported a type 1 diabetes patient who had severe diabetic nephropathy, retinopathy, hypertension, and hypothyroidism before pregnancy. The patient's blood glucose control was poor before pregnancy, and the complications were not properly treated. This was an unintended pregnancy, with a pre-pregnancy glycated hemoglobin A1c of 7.8% and early pregnancy urine protein of 3.81-4.53 g/24 h. Considering the patient's poor blood glucose control before pregnancy and the lack of proper treatment for multiple complications including nephropathy, a multidisciplinary consultation at an external hospital recommended termination of the pregnancy. However, the patient was determined to continue the pregnancy and was referred to Peking University First Hospital. Through strict blood glucose control, monitoring and evaluation of complications, and comprehensive management, the patient's blood glucose and blood pressure were well controlled during pregnancy. Regular monitoring of urine protein, renal function, and ocular fundus was conducted. At 31 weeks and 4 days of gestation, the patient's 24-hour urine protein significantly increased. After promoting fetal lung maturity, a cesarean section was performed at 34 weeks and 1 day of gestation, resulting in a successful delivery with good maternal and neonatal outcomes. At the 42-day postpartum follow-up, the patient's blood glucose and blood pressure were stable, urine protein returned to pre-pregnancy levels, and the infant was in good general condition.
