Objective:To investigate the clinicopathological features, treatment and prognosis of patients with angioimmunoblastic T-cell lymphoma (AILT) complicated with Epstein-Barr virus (EBV)-positive diffuse large B-cell lymphoma (DLBCL).Methods:The clinical data of 2 cases of AILT with EBV-positive DLBCL in the Fifth Medical Center of PLA General Hospital were retrospectively analyzed, and the literature was reviewed.Results:One case of complex lymphoma (CL) developed from low fever with systemic superficial lymphadenopathy, the right axillary tumor biopsy showed that AILT complicated with EBV-positive DLBCL. After 8 cycles of chemotherapy, the patient reached unconfirmed complete remission, then received maintenance treatment with chidamide and survived until the deadline. Another case of discordant lymphoma began with subcutaneous nodules and then developed progressive enlargement of superficial lymph nodes. The pathological examination of subcutaneous nodule diagnosed as DLBCL, and the pathological examination of right inguinal lymph node diagnosed as AITL. After 7 cycles of chemotherapy, the patient died of hemophagocytic syndrome.Conclusions:AILT with EBV-positive DLBCL is rare. The main clinical symptom is AITL and the immunophenotypic characteristic indicates the presence of T cells and B cells. At the same time, the prognosis is poor, and the treatment strategy mainly depends on the lymphoma type with unfavorable prognosis.

Objective To establish a method to simultaneously determinate cobalt, nickel, arsenic, molybdenum, silver, cadmium and lead in blood and urine using inductively coupled plasma tandem mass spectrometry (ICP-MS/MS). Methods The blood samples were diluted 20 times with a mixed solution of nitric acid (0.10% V/V) and Triton X-100 (0.02% V/V). The urine samples were diluted 10 times with nitric acid (1.00% V/V). Yttrium-89, rhodium-103, and lutetium-175 were used as internal standards to decrease matrix interference, and either On-Mass mode or Mass-Shift mode was used to decrease mass spectrometry interference, with detection by ICP-MS/MS. Results The linear ranges of the seven elements were 0.100-10.000 μg/L, with the correlation coefficient >0.999 9. The detection limits for the seven elements in the blood and urine were 0.003-0.021 and 0.003-0.031 μg/L, respectively, and the minimum quantification limits were 0.009-0.064 and 0.009-0.094 μg/L, respectively. The recovery rates were 96.64%-102.90% and 96.34%-104.50% for the blood and urine, respectively. The within-run relative standard deviations (RSDs) were 0.32%-2.33% and 0.25%-2.31%, and the between-run RSDs were 1.07%-3.81% and 1.30%-3.62% for blood and urine, respectively. The samples were stable at 4 ℃ for at least 14 days. Conclusion ICP-MS/MS is a simple, sensitive, and accurate method for rapid detection of seven heavy metal elements in the blood and urine of occupational hazard-exposed workers.
