High mobility group box-1 protein (HMGB1) has recently been shown as a crucial late mediator of inflammation and sepsis, and is involved in mediating multi-organ functional lesions, including acute lung, liver, and intestine injuries. As a delayed inflammatory cytokine, HMGB1 provides a wider therapeutic time window for clinical intervention. HMGB1 has been proven to be a promising therapeutic target to prevent the development of multiple organ dysfunction syndrome in experimental models of severe sepsis. The pharmacological strategies include neutralization of antibodies or specific HMGB1 antagonists, suppression of HMGB1 secretion (ethyl pyruvate, agonists for alpha7-nicotinic acetylcholine receptors), and down-regulation of HMGB1 expression (sodium butyrate, signaling inhibitors for Janus kinase/signal transducer and activator of transcription).

Melanin is formed by oxidative polymerization of phenolic compounds,basically different kinds of melanin come from different organisms.DOPA melanin and DHN melanin have same physical and chemical characters although they have different biosynthetic pathway.DHN melanin is common in plant fungi and plays an important role on infection.The melanin accumulates in the fungal cell walls and prevents organic and inorganic molecules penetrating out,that insures appressorium's pressure and infection ability.This paper has reviewed the kinds and characters,especially discussed the role of melanin during pathogen infection based on our some research.

BACKGROUND: High mobility group box 1 protein (HMGB1) is a highly conserved, ubiquitous protein in the nuclei and cytoplasm of nearly all cell types. HMGB1 is secreted into the extracellular milieu and acts as a proinflammatory cytokine. In this article we reviewed briefly the cellular immune response mediated by HMGB1 in inflammation and sepsis. METHODS: This systemic review is mainly based on our own work and other related reports. RESULTS: HMGB1 can actively affect the immune functions of many types of cells including T lymphocytes, regulatory T cells (Tregs), dendritic cells (DCs), macrophages, and natural killer cells (NK cells). Various cellular responses can be mediated by HMGB1 which binds to cell-surface receptors [e.g., the receptor for advanced glycation end products (RAGE), Toll-like receptor (TLR)2, and TLR4]. Anti-HMGB1 treatment, such as anti-HMGB1 polyclonal or monoclonal antibodies, inhibitors (e.g., ethyl pyruvate) and antagonists (e.g., A box), can protect against sepsis lethality and give a wider window for the treatment opportunity. CONCLUSION: HMGB1 is an attractive target for the development of new therapeutic strategies in the treatment of patients with septic complications.

During the washing process of coarse bear gall powder extracts, it is necessary to adjust the amount of ethyl acetate according to the properties of raw materials, which aims to improving the yield and purity of the final product. In the research, using NIR spectra to reflect the comprehensive properties of coarse bear gall powder extracts, the process is optimized in a flexible way. Forty batches experiments are designed according to the weight ratio of ethyl acetate and coarse extracts of bear gall powder. The NIR spectra of the coarse extracts of bear gall powder are collected and processed using principal component analysis (PCA) method. The first 8 principal components combined with the amount of the ethyl acetate are used as the input variables, and calibration models are established to predict the yield and purity of the final product 30 batches are used as calibration set, which is used to establish the models, and other 10 batches are used as validation set, which is used for the performance appraisal of the established models. The correlation coefficients of the calibration, inner cross-validation and external validation for the purity model are 0.902, 0.896 and 0.883, respectively, and the RMSEC, RMSECV and RMSEP are 1.22%, 1.48% and 1.59%, respectively. The correlation coefficients of the calibration, inner cross-validation and external validation for the yield model are 0.921, 0.859 and 0.916, respectively, and the RMSEC, RMSECV and RMSEP are 1.39%, 1.65% and 1.53% respectively. This work demonstrated that NIR spectra combined with technology parameter could be used to predict the yield and purity of the final product. Using the established models, the most appropriate amount of the ethyl acetate can be determined according to the properties of the coarse bear gall powder extracts, and the yield and purity of the final product can be improved.
