Objective: To investigate the killing activity of cytokine-induced killer (CIK) cells after incubation with autologous tumor cell lysate-pulsed dendritic cells (Ag-DC) and to evaluate the immune functions of patients, the clinical efficacy and side effect of Ag-DC in combination with CIK on hepatocellular carcinoma. Methods: Peripheral blood mononuclear cells were isolated from 24 patients with hepatocellular carcinoma, and cultured with granulocyte-macrophage colony-stimulating factor and interleukin-4 to produce dendritic cells (DCs). The DCs were pulsed with autologous tumor cell lysate. T lymphocytes from PBMC were cultured with interferon-Y (IFN-γ), IL-2, CD3-moAb, and IL-1α to prepare CIK. The killing effect of CIK on SMMC-7721 was investigated after CIK was incubated with Ag-DC. After immunotherapy with Ag-DC and CIK, immunolog-ic and clinical responses of the 24 patients were evaluated. Results: The killing effect of CIK was remarkably improved after CIK was incubated with Ag-DC. The immunotherapy with DC and CIK alleviated symptoms and improved the immune functions of the patients. Except for transient fever and chill, no remarkable adverse events were observed. Conclusion: Ag-DC in combination with CIK shows short-term efficacy on hepatocellular carcinoma through inducing specific anti-tumor immunity and can be an effective adjuvant therapy for hepatocellular carcinoma.

Objective:To explore the relevant predictive indicators of fever course > 7 days in children with infectious mononucleosis.Methods:The clinical data of 163 children with infectious mononucleosis who received treatment in Xi'an Children's Hospital from January 2018 to October 2020 were retrospectively analyzed. According to the heat duration, the children were divided into the fever course > 7 days group ( n = 55) and the fever course ≤ 7 days group ( n = 108). The clinical manifestations and laboratory indexes on admission were compared between the two groups. A logistic regression model was used to analyze the influential factors of fever course in children. A receiver operating curve was used to evaluate the predictive value of heat course > 7 days for infectious mononucleosis. Results:The majority of children with infectious mononucleosis had a heat course of 7 days (21.5%). There were no significant differences in clinical manifestations between the fever course > 7 days group and the fever course ≤ 7 days group (all P > 0.05). Neutrophil count, the proportion of monocytes, aspartate aminotransferase, and the proportion of suppressor T (Ts) cells in the fever course > 7 days group were (15.97 ± 7.60) × 10 9/L, 7.75 (4.93, 10.75)%, 53.00 (22.00, 91.50) U/L, 70.00 (57.00, 75.00)%, respectively, which were significantly higher than (15.21 ± 5.29) × 10 9/L, 5.40 (3.40, 9.60)%, 40.00 (30.00, 63.75) U/L, 63.50 (55.00,70.75)% in the fever course ≤ 7 days group ( t = -5.10, Z = -2.31, Z = -2.26, Z = -2.12, all P < 0.05). The proportion of helper T (Th) cells and the ratio of Th/Ts cells in the fever course > 7 days group were 13.00 (9.00, 17.00)% and 0.19 (0.12, 0.30)%, respectively, which were significantly lower than 16.00 (12.25, 20.75)%, 0.26 (0.18, 0.37)% in the fever course ≤ 7 days group ( Z = 2.44, 2.48, both P < 0.05). Multivariate logistic regression analysis showed that the increased proportion of Ts cells ( OR = 0.96, 95% CI 0.922-0.978, P < 0.05) was an influential factor of the prolonged course of fever. The area under the receiver operating characteristic curve of the proportion of Ts cells was 0.637. The cut-off value, sensitivity, and specificity were 67.50%, 61.3%, and 64.3%, respectively. Conclusion:Children with infectious mononucleosis with a longer heat course have more severe immune responses. The proportion of Ts cells > 67.5% can be used as a risk factor for the fever course > 7 days in children with infectious mononucleosis.
