Objective To investigate the prevalence of thyroid nodules in the physical examination population in Mianyang region and analyze its association with metabolic syndrome. Methods A retrospective study was conducted on 9 978 individuals who underwent health examinations at our hospital from January 2024 to May 2025. Thyroid examinations were performed using color Doppler ultrasound to analyze the prevalence of thyroid nodules in this population. Clinical data of all subjects were collected, and logistic regression analysis was employed to assess the association between metabolic syndrome and the risk of thyroid nodule development. Results The prevalence of thyroid nodules in the physical examination population of Mianyang region was 17.98% (1 794/9 978). The logistic regression results showed that after adjusting for gender, age, BMI, occupation, consumption of non-iodized salt, staying up late, daily sleep duration, anxiety, and depression, metabolic syndrome (OR=6.593, 95% CI: 3.961-10.975) was associated with thyroid nodules (P<0.05). Conclusion The prevalence of thyroid nodules among the physical examination population in the Mianyang area is 17.98%, and metabolic syndrome remains associated with the risk of thyroid nodules after effectively controlling for confounding factors.

Objective:This study aimed to achieve the early diagnosis and active treatment of adult hemophagocytic syndrome (HPS) and investigate the clinical characteristics and prognostic factors of this syndrome. Methods:A single-center retrospective analysis was performed to analyze clinical characteristics, laboratory findings, and survival data. Results:In 58 patients, the most common clinical manifestations were fever (100%) and splenomegaly (89.7%). The most common laboratory parameters were serum ferritin 500 g/L (100%) and peripheral cytopenia in two or more lineages (96.6%). platelet count, fibrinogen, and lactate dehydrogenase in the death group were significantly lower than in the survival group (P=0.000, 0.001, and 0.000). Survival analysis results showed that infections in the rheu-matological group exhibited good prognosis [the overall survival (OS) time was not reached in 190 d]. Patients with unexplained causes had moderate prognosis (OS time was 60 d);tumor-associated HPS patients had poor prognosis (the OS time was only 30 d). Univariate analysis results showed that patients with Fbg<1.5 g/L, PLT<40×109/L, and LDH≥2000 U/L also exhibited poor prognosis (P=0.000). Multivariate analysis results showed that PLT<40 × 109/L was an independent adverse factor (HR=6.472, 95%CI:1.526-26.065, P=0.011). Conclusion:HPS exhibits complex clinical manifestations and varied etiology. Patients with infection and rheumatism-related HPS had good prognosiss compared with those manifesting tumor-associated HPS. Fbg<1.5 g/L, PLT<40×109/L, and LDH≥2 000 U/L were the univariate factors that affected the survival time of patients. PLT<40×109/L is an independent adverse factor. These patients need systemic treatments as early as possible.

Objective To explore the validity of simulative employment training course on enhancing the core competitiveness of university students.Method We investigate the students with simulative employment trainin, graduates and recruiters through interview, symposium and questionnaire survey. Results The comprehensive quality and occupational capacity of students that completed simulative employment training had been improved. In the simulative employment training course,98%students thought their interview skills had been promoted, 90%recruiters were satisfied with the students,95%graduates who had worked consider that the simulative employment training were helpful. Conclusions Simulative employment training is effective for enhancing the core competitiveness of university students.
