Background: Outbreaks of silicosis have occurred among workers in the artificial stone (AS) industry, and there is currently no effective antifibrosis treatment for silicosis.

Design: A retrospective cohort study.

Methods: We retrospectively analyzed the clinical data of 89 artificial stone-associated silicosis patients treated in Shanghai Pulmonary Hospital (China).

This study was performed to compare the differences in pH, myofibril fragmentation index (MFI), total protein solubility (TPS), sarcoplasmic protein solubility (SPS), myofibrillar protein solubility (MPS), and the microstructure of seven beef muscles during aging. From the six beef carcasses of Xinjiang brown cattle, a total of 252 samples from (ST), (LT), (RH), (GN), (IN), (PM), and (BF) muscles were collected, portioned, and assigned to six aging periods (1, 3, 7, 9, 11, and 14 day/s) and 42 samples were used per storage period. IN muscle showed the highest pH ( < 0.

Antibody responses can be useful markers of tuberculosis (TB) infection, especially in the screening of extra-pulmonary TB. MPT64 is an important antigen in Mycobacterium tuberculosis (MTB) infection and is used in serological diagnosis. However, large variability in the diagnostic accuracy of MPT64 as a serological tool has limited its application.

Objective: To compare the clinical efficacies of humeral head prosthesis and internal fixation in the treatment of comminuted proximal humeral fractures.

Methods: The clinical data were analyzed for the patients with comminuted proximal humeral fractures undergoing surgeries for humeral head replacement or open reduction plus internal fixation in our hospital between January 2002 and January 2009. Constant scores were used to determine the excellent clinical outcome rates in the two groups, and the operating time, blood loss and postoperative motor scores of the shoulder were compared.

Objective: To identify the Mycobacterium tuberculosis complex by detecting the secretory protein MPT64.

Methods: The gene mpt64 was amplified by polymerase chain reaction (PCR) from the genome of Mycobacterium tuberculosis H(37)Rv strain and cloned into expression vector. Immune sera from rabbits by recombinant proteins MPT64, were used to make enzyme-labeled antibodies and coated antibodies.

Objective: To construct a human phage display single-chain Fv (ScFv) antibody library against Mycobacterium tuberculosis (MTB), for specific ScFv antibody cloning.

Methods: Total RNA was isolated from the lymphocytes of patients with positive serum antibody against MTB and reverse transcribed into cDNA. The heavy chain and light chain variable region gene of human immunoglobulin were amplified individually by PCR and then assembled into ScFv genes.

Resident peritoneal macrophages (pMphi) are found deficient in T cell-stimulating capacity compared with the competent splenic macrophages (sMphi). Macrophages (Mphi)-derived nitric oxide (NO) and IL-12 have been shown to play crucial roles in the interaction between Mphi and T cells. To further understand differential functions between pMphi and sMphi, we focused on the production of NO and IL-12 from LPS plus IFN-gamma-activated Mphi.

Aim: To investigate the effects of triptolide, a diterpenoid triepoxide from Tripterygium wilfordii Hook F (TWHF), on the co-stimulatory molecule expression and interleukin-12 (IL-12) production from THP-1 cells.

Methods: THP-1 cells were differentiated into macrophage-like cells by Me2SO, and then cultured with IFN-gamma (500 kU/L) and lipopolysaccharide (LPS) (1 mg/L) with or without triptolide. The surface molecule expressions were analyzed on a FACScan flow cytometer.

Lymphocytes depend on transmethylation reactions for efficient activation and function. These reactions are primarily catalyzed by S-adenosylmethionine-dependent methyltransferases, which convert S-adenosylmethionine to S-adenosyl-L-homocysteine. S-adenosyl-L-homocysteine is then hydrolyzed by S-adenosyl-L-homocysteine hydrolase to prevent feedback inhibition of transmethylation reactions.

Resveratrol, a polyphenol compound found in grapes and red wines, is a prominent anti-cancer agent. In this study, we demonstrate that resveratrol enhanced TNF-alpha, IL-12 and IL-1beta production from LPS activated phorbol myristate acetate (PMA) differentiated THP-1 human macrophages. Expression of CD86 on macrophages was enhanced by resveratrol alone and with LPS.

Aim: To study the interaction of resveratrol and ethanol on the production of pro-inflammatory factors from activated murine peritoneal macrophages (MPM).

Methods: NO production was measured with Griess assay; IL-1 production was measured through thymocyte co-stimulating assay; IL-6 and TNF-alpha were detected by ELISA method.

Results: Resveratrol (6.

Aim: To study the immune modulating effect of low dose of resveratrol.

Methods: Concanavalin A (ConA) and Staphylococcus aureus Cowan (Sac) were used to induce the activation of T lymphocyte and antigen presenting cell and cytokine production. [3H]-Thymidine incorporation was used to evaluate the proliferation of lymphocyte.
