[Expressions of CXCL8, CXCL10 and Th1 /Th2 cytokines in the serum and cerebrospinal fluid of patients with neurosyphilis].

Objective: To investigate the levels of chemokines 8 and 10 (CXCL8 and CXCL10), Th1 cytokines (IL-2, IL-12 and IFN-γ) and Th2 cytokines (IL-6 and IL-10) in the serum and cerebrospinal fluid of patients with neurosyphilis and elucidate their roles in the immune response and pathogenesis of neurosyphilis.

Methods: Using ELISA, we detected the expressions of CXCL8, CXCL10, IL2, IL-2, IFN-γ, IL-6 and IL-10 in the serum and cerebrospinal fluid of 42 cases of neurosyphilis, 44 cases of syphilis and 40 cases of non-inflammatory diseases of the nervous system (the control group).

Results: The serum levels of CXCL8, CXCL10, IL-2, IL-12, IFN-γ, IL-6 and IL-10 were significantly lower in the neurosyphilis group than in the syphilis and control groups (P < 0.

The clinical features, treatment, and prognosis of primary mediastinal malignant melanoma: A case report.

Rationale: Primary malignant melanoma (MM) of the mediastinum is exceedingly rare; a review of the English-language literature reveals only a small number of case reports. In this paper, we discuss a case of primary mediastinal MM and present a review of the relevant literature on its clinical features and treatment.

Patient Concerns: A 52-year-old male presenting with back pain was admitted to our hospital for treatment.

New T cell epitopes identified from an anti-idiotypic antibody mimicking ovarian cancer associated antigen.

Anti-idiotype (Id) antibodies can be used to induce specific cellular immune responses against tumor antigens, but the mechanism of antigenicity is not always clear. We previously reported an anti-Id antibody, 6B11, which mimics human ovarian cancer associated antigen OC166-9. To explore the molecular basis of cellular immune response induced by 6B11, a panel of peptides derived from complementarity determining region (CDR) of 6B11 were synthesized.

Dynamic phosphorus budget for lake-watershed ecosystems.

Lake eutrophication caused by excess phosphorus (P) loading from point sources (PS) and nonpoint sources (NPS) is a persistent and serious ecological problem in China. A phosphorus budget, based on material flow analysis (MFA) and system dynamic (SD), is proposed and applied for the agriculture-dominated Qionghai Lake watershed located in southwestern China. The MFA-SD approach will not only cover the transporting process of P in the lake-watershed ecosystems, but also can deal with the changes of P budget due to the dynamics of watershed.
