S100A8, an important member of the S100 protein family, is a low-molecular-weight (10.8 kDa) calcium-binding protein containing conserved EF-hand structural motifs. Previous studies have shown that the biological function of S100A8 protein is associated with a variety of inflammatory diseases, for example asthma. S100A8 protein plays important roles in the regulation of inflammation. It can activate inflammatory cells and cytokines via chemotactic activity for neutrophils, and bind to the receptor for advanced glycation end products (RAGE) and Toll-like receptor 4 (TLR4), thus mediating intracellular inflammatory signaling transduction. Additionally, recent studies have reported the anti-inflammation activity of S100A8 protein, which indicates that S100A8 may have a more complex function of biological regulation in the different pathophysiological conditions. In this review, we summarized the studies on the functions and molecular mechanisms of S100A8 protein in inflammation, which would propose a novel strategy for the prophylaxis and treatment of asthma and other inflammatory diseases.

3.Chronic rhinosinusitis with bronchial asthma, what should we concern about?.
Chinese Journal of Otorhinolaryngology Head and Neck Surgery 2016;51(3):235-240
There is a strong association between chronic rhinosinusitis (CRS) and asthma. Approximately 10%-50% of CRS patients also have comorbid asthma. These patients are more likely to have severe CRS and asthma and higher recurrence rates after sinus surgery. Also there may be acute asthma attack during the perioperative period. Therefore, we should pay more attention to these patients. Assessment of the control level of asthma and pulmonary function should be performed preoperatively. And asthma needs to be fully managed in the perioperative period to avoid acute asthma attack. Extensive sinus surgery is recommended in these patients to reduce the inflammation load. Long-term medical treatment and regular follow-up are suggested to achieve well control of CRS and asthma.

4.Research progress on roles of vitamin D in endometriosis.
Journal of Zhejiang University. Medical sciences 2018;47(4):413-418
In addition to regulating calcium and phosphorus metabolism to maintain strong bones, vitamin D also has immune regulating and anti-inflammatory effects. Moreover, it is related to chronic inflammatory diseases, autoimmune diseases and cancer. Many studies indicate the roles of vitamin D in the development and progression of endometriosis including the effects on modulation of immune responses, inflammation reactions, cell proliferation and apoptosis, angiogenesis, adhesion and invasion. Vitamin D supplementation can relieve pain and improve endometrial receptivity associated with endometriosis and play a preventive and therapeutic role. This paper summarizes the roles of vitamin D in endometriosis.

Chinese Journal of Integrated Traditional and Western Medicine 2015;35(2):243-246
The "Cancer Toxin" pathogenesis theory is an innovate theoretical system for cancer pathogenesis of Chinese Medicine, which was built on the basis of "Cancer Toxin" concept initially raised by Professor ZHOU Zhong-ying. The mechanism of the transformation from inflammation to carcinoma has become one of hot-points in the field of cancer research at home and abroad in recent years. We focused on discussing the relevance of the "Cancer Toxin" pathogenesis theory with the transformation mechanism from inflammation to cancer, provided evidence for using "Cancer Toxin" pathogenesis theory in intervening transformation from inflammation to cancer, hoping to guide for Chinese medical prevention and treatment of tumor.

OBJECTIVE:
To investigate the distribution of airway inflammation phenotype in patients with bronchial asthma (asthma), and to analyze clinical characteristics, inflammatory cytokines, pulmonary small vessels remodeling and small airway wall remodeling in patients with neutrophilic asthma.
METHODS:
Sixty-three patients with asthma were enrolled from January 2015 to December 2015 in Peking University Third Hospital. Clinical data including gender, age, body mass index (BMI), pulmonary function tests (PFTs), asthma control test (ACT) were recorded. All the patients underwent sputum induction. The cellular composition of the sputum was evaluatedand the concentration of active MMP-9 in the sputum tested. Blood routine tests were done and the concentration of IgE, periostin, and TGF-beta1 levels were measured in serum by enzyme-linked immunosorbent assay (ELISA). Small airway wall remodeling was measured in computed tomography (CT) scans, as the luminal diameter, luminal area, wall thickness and wall area % adjusted by body surface area (BSA) at the end of the 6th generation airway, in which the inner diameter was less than 2 mm. Small vascular alterations were measured by cross-sectional area (CSA), and the total vessel CSA < 5 mm2 was calculated using imaging software.
RESULTS:
The distributions of airway inflammatory phenotypes of the asthmatic patients were as follows: neutrophilic asthma (34.9%, 22/63), eosinophilic asthma (34.9%, 22/63), mixed granulocytic asthma (23.8%, 15/63), and paucigranulocytic asthma (6.3%, 4/63). The neutrophilic subtype patients had a significantly higher active MMP-9 level in sputum compared with the eosinophilic phenotypepatuents, as 179.1 (74.3, 395.5) vs. 50.5 (9.7, 225.8), P<0.05. Sputum neutrophil count was negatively correlated with FEV1%pred (r=-0.304,P<0.05), and positively correlated with active MMP-9 level in sputum (r=-0.304, P<0.05), and positive correlation trend with airway wall thickness (r=0.533, P=0.06). There was a significantly negative correlation of active MMP-9 level in sputum with FEV1%pred (r=-0.281, P<0.05), in positive correlation with small airway wall area (%)(r=0.612, P<0.05), and inpositive correlation trend with airway wall thickness (r=0.612, P=0.06). Neutrophils count in peripheral blood was positively correlated with neutrophil counts in sputum.
CONCLUSION
Neutrophil count in airway is related to lung function in asthmatic patients. Neutrophils may accelerate small airway wall remodeling through the release of active MMP-9. Neutrophil count in peripheral blood is related to neutrophils count in sputum, which may be used as a substitute for evaluating inflammatory phenotype.

Asthma is a phenotypically heterogeneous chronic disease of the airways. Studies have found that neutrophils are crucial to airway inflammation in acute asthma, persistent asthma, particularly in asthma of poor response to glucocorticoid treatment. The role of neutrophils in development of bronchial asthma is complex, as they can release a potent source of cytokines and inflammatory mediators participating in asthma. Differing from eosinophilic inflammatory asthma, neutrophilic inflammatory asthma is not depend on helper T (Th)2 cells, but may be related to Th1 and Th17 cells. This review highlights the role of neutrophils in the development of asthma, and the treatment of neutrophilic asthma with biological agents and novel small molecules.

9.Research progress on receptor interacting proteins in inflammation.
Journal of Zhejiang University. Medical sciences 2018;47(1):89-96
Receptor interacting proteins (RIPs) are a group of threonine/serine protein kinases, which have relatively conserved kinase domains and different non-kinase domains, and are involved in physiological and pathological processes including innate immune response and inflammation. In recent years, many studies have shown that RIPs mediate cell necroptosis and triggers inflammatory responses by participating in the formation of necrotic complexes, and RIP1 and RIP3 are particularly closely related to cell necrosis. Cell necroptosis is a well-regulated way of cell death. The death signal that transmit through the TNF signaling pathway and the Toll-like receptor signaling pathway can recruit and phosphorylate mixed lineage kinase domain-like protein (MLKL), and eventually leading to disintegration and death of cells, and the release of cells intercellular material after cell disintegration can trigger an inflammatory reaction. This review mainly focuses on the major signaling pathways and molecular mechanisms that are involved in the mediation of necrosis and inflammation by RIPs. It also highlights the importance of RIPs in the development of inflammatory diseases and their potentials as therapeutic targets for inflammatory diseases.
