The main route of metastasis of bladder urothelial carcinoma is through lymph nodes; however, its exact mechanism remains unclear. In this study, we found an association of nucleolar and spindle associated protein 1 (NUSAP1) expression with BUC tissues along with lymph node metastasis and the survival prognosis. A total of 178 pathological specimens following radical bladder cancer resection were obtained. NUSAP1 expression was analyzed by immunohistochemistry. We evaluated the correlation between clinicopathological characteristics and NUSAP1 expression. Logistic regression was used to determine the independent variables that influenced lymph node metastasis. Uni- and multi-factorial Cox regression methods were used to determine the prognostic value of NUSAP1 expression in urothelial carcinoma of the bladder. High expression of NUSAP1 in BUC was not significantly related to the patient’s gender, age, or tumor number (p > 0.05), however was significantly associated with pathological grade, tumor diameter, pathological stage, and lymph node metastasis (p < 0.05). Lymph node metastasis was significantly correlated with pathological stage, pathological grade, tumor number, tumor diameter, and NUSAP1 expression (p < 0.05); only NUSAP1 expression was an independent predictor of lymph node metastasis in BUC (OR:1.786, 95% CI 1.229–2.596, p = 0.002). In addition, high NUSAP1 expression was an independent prognostic predictor for BUC. In BUC, NUSAP1 showed high expression and was significantly associated with lymph node metastasis, pathological stage, pathological grade, and tumor diameter. NUSAP1 was an independent predictor of lymph node metastasis and prognosis in BUC; higher expression indicated poorer prognosis of BUC patients.

Background: Adrenocorticotropic hormone (ACTH)-independent Cushing's syndrome (CS) with right adrenal adenoma combined with HIV infection has rarely been reported. Case presentation: A 39-year-old Chinese male patient with HIV infection was admitted to our hospital due to increased blood pressure in the previous 2 years and weight gain in the previous 6 months. Endocrinological examinations showed that blood cortisol (8 a.m.) was 22.23 µg/dl, the level of ACTH (8 a.m.) was less than 1pg/ml and twenty-four-hour urinary cortisol was 1429 µg/24h. ACTH-independent CS was diagnosed based on low ACTH levels (<1.00 pg/ml), a lack of cortisol circadian rhythms and unsuppressed cortisol levels by dexamethasone. The ultrasonography and multislice spiral computed tomography scan revealed a right adrenal mass. Due to the HIV status of the patient, we measured the count of CD4+ T helper cells. Laparoscopic right adrenal resection was performed after the CD4+ T helper cell count was > 200 cells/µl. Subsequent immunohistochemical staining confirmed right adrenal adenoma. Results: The postoperative recovery was good, and wound healing was possible. After surgical treatment, endocrinological examinations indicated that the level of ACTH increased and the levels of serum cortisol and twenty-four-hour urinary cortisol decreased, which indicated that CS was controlled. CD4/CD8 was 0.47 at reexamination, and the patient's immunity was improved. Conclusion: Due to the potential side effects of steroid drugs, clinicians should use these medications with caution and closely monitor the development of adrenal deficiency.
