RESUMO
BACKGROUND: Hepatocellular carcinoma (HCC) (about 85-90% of primary liver cancer) is particularly prevalent in China because of the high prevalence of chronic hepatitis B infection. HCC is the fourth most common malignancy and the third leading cause of tumor-related deaths in China. It poses a significant threat to the life and health of Chinese people. SUMMARY: This guideline presents official recommendations of the National Health and Family Planning Commission of the People's Republic of China on the surveillance, diagnosis, staging, and treatment of HCC occurring in China. The guideline was written by more than 50 experts in the field of HCC in China (including liver surgeons, medical oncologists, hepatologists, interventional radiologists, and diagnostic radiologists) on the basis of recent evidence and expert opinions, balance of benefits and harms, cost-benefit strategies, and other clinical considerations. KEY MESSAGES: The guideline presents the Chinese staging system, and recommendations regarding patients with HCC in China to ensure optimum patient outcomes.
RESUMO
OBJECTIVE: To examine the nephrotoxicity induced caused by combined effect of arsenic and cadmium in exposed workers. METHODS: Urinary cadmium and arsenic were used as the exposure biomarkers of cadmium and arsenic. Urinary beta2-microglobulin (Ubeta2-MG), albumin (UALB) and N-acetyl-beta-D-glucosaminidase (UNAG) were measured as the effective biomarkers of tubular and glomerular dysfunction induced by cadmium and arsenic. RESULTS: The combination of cadmium and arsenic induced more severe renal injury than that caused by either of the chemicals given alone. There were positive correlations and significant dose-effect among the concentrations of urinary cadmium, arsenic and levels of Ubeta2-MG, UALB, UNAG (P<0.05, P<0.01). CONCLUSION: Cadmium combined with arsenic may have additive effect on renal dysfunction in workers exposed to arsenic and cadmium.
