Objective:To explore the clinical characteristics, diagnosis and treatment strategies, and prognosis of pulmonary embolism (PE) complicating childhood rheumatic diseases.Methods:A retrospective case series study was performed on the demographic data, laboratory indicators, imaging features, treatment regimens, and follow-up data of 8 children with rheumatic diseases complicated by PE who were admitted to the Department of Rheumatology and Immunology, Capital Center for Children′s Health, Capital Medical University from January 2014 to October 2023.Results:Among the 8 children, there were 4 boys and 4 girls, with an age of 12.0 (7.5, 13.0) years. Among the primary diseases, there were 3 cases of systemic lupus erythematosus, 2 cases of Beh?et′s disease, 2 cases of Takayasu arteritis, and 1 case of antiphospholipid syndrome. All children developed PE during the active phase of the primary disease. PE was detected at the onset of the primary disease in 3 cases, and the median time from the diagnosis of the primary disease to the development of PE was 10.0 (6.0, 25.0) months in the remaining 5 cases. Fever was present in all 8 children, 4 cases were accompanied by chest tightness, dyspnea, etc., and 2 cases only presented with fever. Laboratory examinations revealed the following results: erythrocyte sedimentation rate was 42.0 (17.0, 78.0) mm/1 h, high-sensitivity C-reactive protein was 12.7 (2.6, 78.7) mg/L, white blood cell count was 9.6 (7.2, 18.7)×10 9/L; D-dimer was 2.3 (0.9, 6.2) mg/L; and hemoglobin was (109±16) g/L.Imaging examinations revealed that 5 cases had involvement of the bilateral lower pulmonary arteries, 5 cases had peripheral embolism, and 3 cases had central PE. Complications included 3 cases of deep vein thrombosis, 2 cases of intracranial venous sinus thrombosis, and 1 case of mild pulmonary hypertension.In terms of treatment, 7 cases received anticoagulation with heparin followed by warfarin. Immunomodulation was mainly based on glucocorticoids combined with immunosuppressants, and 4 cases were combined with biological agents. The follow-up time of 4.17 (1.75, 7.17) years, the time for complete absorption of PE was 10.5 (6.0, 18.0) months; all 8 children had no target events, with no recurrence or chronic thromboembolic pulmonary hypertension, and the pulmonary artery remodeling was good. Conclusions:PE complicating childhood rheumatic diseases is closely related to the activity of the primary disease. The clinical manifestations are insidious, with fever as the main symptom. Imaging examination is the key to diagnosis.Early adoption of heparin followed by warfarin anticoagulation and glucocorticoids combined with immunosuppressants and (or) biological agents to control the primary disease can achieve a favorable prognosis.

OBJECTIVE: Exposure to polycyclic aromatic hydrocarbons (PAHs) or metal(loid)s individually has been associated with neural tube defects (NTDs). However, the impacts of PAH and metal(loid) co-exposure and potential interaction effects on NTD risk remain unclear. We conducted a case-control study in China among population with a high prevalence of NTDs to investigate the combined effects of PAH and metal(loid) exposures on the risk of NTD. METHODS: Cases included 80 women who gave birth to offspring with NTDs, whereas controls were 50 women who delivered infants with no congenital malformations. We analyzed the levels of placental PAHs using gas chromatography and mass spectrometry, PAH-DNA adducts with ³²P-post-labeling method, and metal(loid)s with an inductively coupled plasma mass spectrometer. Unconditional logistic regression was employed to estimate the associations between individual exposures and NTDs. Least absolute shrinkage and selection operator (LASSO) penalized regression models were used to select a subset of exposures, while additive interaction models were used to identify interaction effects. RESULTS: In the single-exposure models, we found that eight PAHs, PAH-DNA adducts, and 28 metal(loid)s were associated with NTDs. Pyrene, selenium, molybdenum, cadmium, uranium, and rubidium were selected through LASSO regression and were statistically associated with NTDs in the multiple-exposure models. Women with high levels of pyrene and molybdenum or pyrene and selenium exhibited significantly increased risk of having offspring with NTDs, indicating that these combinations may have synergistic effects on the risk of NTDs. CONCLUSION Our findings suggest that individual PAHs and metal(loid)s, as well as their interactions, may be associated with the risk of NTDs, which warrants further investigation.

Objective:To investigate the prevalence of baseline dyslipidemia in HIV-infected people before starting antiviral therapy (ART) in China.Methods:The data were collected from HIV/AIDS ART database of Chinese Disease Prevention and Control Information System. A national sample of HIV- infected people who initiated ART from 2018 to 2023 was used to collect baseline information, including sociodemographic characteristics and laboratory test results. According to the Chinese Lipid Management Guidelines (2023) and the National Cholesterol Education Program Adult Treatment Panel Ⅲ guidelines, triglyceride (TG) ≥1.7 mmol/L or total cholesterol (TC) ≥5.2 mmol/L were identified as dyslipidemia. Statistical analysis was performed with software SAS 9.4. An unconditional logistic regression model was used to analyze the factors influencing TG and TC abnormalities in HIV-infected patients before ART.Results:A total of 359 952 adults infected with HIV were included in this study, the prevalence rate of dyslipidemia was 38.41% (138 263/359 952). The abnormal rates of TG and TC were 31.40% (113 041/359 952) and 13.75% (49 494/359 952), respectively. In all age groups except for the 25-44 age groups, the abnormal rates of TG and TC were higher in HIV-infected women than in HIV-infected men. In HIV-infected patients, women, those aged 45-64 years, those lived in northeast region, those had heterosexual transmission, and those with BMI ≥28.0 kg/m 2, CD4 +T lymphocytes counts ≥500 cells/μl had higher rates of baseline dyslipidemia (all P<0.05). Conclusions:The abnormal rate of TG in HIV-infected people before ART was higher in China from 2018 to 2023, especially in HIV-infected women, and the abnormal rate of TG and TC increased with age. Attention should be paid to the clinical diagnosis and ART selection in the treatment of HIV infection.

Alexithymia refers to a deficiency of emotional structure, but the neurologic and psychological mechanisms of non-suicidal self-injury (NSSI) in adolescents are still unclear. The neural basis of alexithymia may play a role in adolescents′ NSSI by affecting the function of emotion regulation and emotion expression. At the same time, NSSI is also considered to be a non-adaptive emotional regulation mode for alexithymia individuals, which interacts with personality factors and psychosocial factors. This study explored the neuropsychological mechanism of alexithymia in adolescent NSSI from the perspective of emotional function, and provided theoretical basis for early identification and precise intervention of alexithymia and adolescent NSSI.
