Objective: To evaluate the effects of thermochemotherapy on the immunologic function of lip cancer patients and to provide a theoretical basis for the clinical application of thermochemotherapy.
Methods: Twenty patients were heated by microwave at (42.5 +/- 0.2) degree C for 40 minutes after venoclysis of Pingyangmycin (8 mg) and Methotrexate (20 mg). Each of the patients received the therapy twice a week for 5 weeks. Venous blood was obtained before the first thermochemotherapy and after the tenth thermochemotherapy. Lymphocyte transformation index was examined by 3H-TdR method, and CD4+ and CD8+ T cells were assayed by flow cytometry.
Results: The tumors of the 20 patients were completely extinctive. The lymphocyte transformation index after treatment was significantly higher than that before treatment (P < 0.01). The CD4+ T cells and CD4+/CD8+ after treatment were significantly higher than those before treatment (P < 0.05); the CD8+ T cells after treatment was lower than that before treatment, but there was no statistically significant difference (P > 0.05).
Conclusion: Thermochemotherapy can enhance the lip cancer patient's T lymphocyte immunologic function, which possibly plays an important role in the treatment of lip cancer.

Hemophagocytic lymphohistiocytosis (HLH) is a rare but potentially fatal entity characterized by an unregulated activation of the immune system. In the adult population, it is most commonly secondary to infectious, autoimmune, or neoplastic diseases. We present a case of a 23-year-old female diagnosed with infectious mononucleosis and hospitalized due to a persistent three-week fever and malaise with a new onset of jaundice and findings compatible with acute hepatitis and hepatosplenomegaly.

The proliferation of CAR-T cells was hindered and cannot play its killing function well in solid tumors. And yet the regulatory mechanism of CAR-T cell proliferation is not fully understood. Here, we showed that recombinant expression of CD19CAR in T cells significantly increased the basal activation level of CAR-T cells and LCK activation.

BACKGROUND Recipient hepatic arteries are generally used for arterial reconstructions in living donor liver transplantation. When the hepatic arteries are not feasible, the right gastroepiploic artery is one of the options for arterial reconstructions. In this study, we evaluate the feasibility of using the right gastroepiploic artery and report the analyzed retrospective patient outcomes.

Introduction: We have reanalyzed the genomic data from the International Collaboration for the Genomics of HIV (ICGH), focusing on HIV-1 Elite Controllers (EC).
Methods: A genome-wide association study (GWAS) was performed, comparing 543 HIV-1 EC individuals with 3,272 uninfected controls (CTR) of European ancestry. 8 million single nucleotide polymorphisms (SNPs) and HLA class I and class II gene alleles were imputed to compare EC and CTR.
