To research the heat transfer characteristics and thermogravimetric change of coal-based activated carbon during oxidation, and collected three kinds of coals in the production process of coal-activated carbon: briquette, carbonized materials, activate material. Laser thermal conductivity meter and thermogravimetric-differential thermal simultaneous thermal analyzer were used to measure the thermophysical properties and thermal weight loss parameters in the sample oxidation process, combined with the nonlinear oxidation thermodynamic method, and the apparent activation energy is calculated. The results demonstrated that the total heat release and maximum heat release rate of the activated material and the carbonized material are greater than briquette material. Thermal physical parameters show obvious stage characteristics. The order of thermophysical parameters to temperature sensitivity of the sample is: specific heat capacity > thermal diffusion coefficient > thermal conductivity; the apparent activation energy of activated materials and carbonized materials is less than that of pressed materials, the oxidized spontaneous combustion tendency increases after carbonization and activation process.

Objective To investigate the alterations of soluble molecule programmed death 1 (sPD-1) and soluble programmed death ligand 1 (sPD-L1), as well as related Th1 cytokines IFN-γ and Th2 cytokines IL-4 in patients infected with Brucella. Methods The study enrolled 56 patients infected with Brucella and 48 healthy controls. Serum sPD-1 and sPD-L1 were detected by ELISA and the levels of Th1/Th2 cytokines were measured with cytometric bead array (CBA). Among them, 37 patients received follow-up. Results Compared with the control group, the serum levels of sPD-1/sPD-L1 and IL-4 increased significantly, while the level of IFN-γ decreased significantly. In the 37 patients receiving follow-up after treatment, serum levels of sPD-1/sPD-L1 and IL-4 were remarkably lower than those in pretherapy, while the level of IFN-γ was obviously higher than that in pretherapy. Conclusion The increase of sPD-1 and sPD-L1 may be involved in the process of Brucella infection.

Objective To oberseve the expressions of B cell lymphoma 6 (Bcl-6) and B lymphocyte-induced maturation protein 1 (Blimp-1) in the decidua of patients with unexplained recurrent spontaneous abortion (URSA), and investigate the roles that Bcl-6 and Blimp-1 act in URSA. Methods Decidual tissues were collected from patients with URSA (URSA group) and normal pregnant women (control group). Then, we detected the expressions of Bcl-6 and Blimp-1 in the deciduas of the two groups using real-time fluorescent quantitative PCR and immunohistochemistry. The relationship between Blimp-1 and Bcl-6 was estimated by Pearson's correlation analysis. Results Compared with the control group, the levels of Blimp-1 mRNA and protein, Bcl-6 mRNA significantly increased in the URSA group. However, Bcl-6 protein was raised insignificantly in URSA group. Furthermore, there was a positive correlation between Bcl-6 and Blimp-1 at the level of mRNA. Conclusion The expressions of Bcl-6 and Blimp-1 are enhanced in the deciduas of URSA patients.
