CD4+CD25+调节T细胞与全身炎症反应综合征

全身炎症反应综合征（SIRS）是指由外伤、感染、烧伤、手术、胰腺炎以及缺血一再灌注等多种因素引起的一种全身炎症反应。其基本特征是炎症介质“瀑布样释放”，炎症反应失控，机体内促炎一抗炎自稳失衡，免疫防御功能下降，最终导致多器官功能障碍综合征（MODS）。炎性介质和抗炎介质的平衡失调是SIRS发展为MODS的关键环节，因此早期预测和有效干预SIRS，实现炎症介质和抗炎介质的平衡是防治MODS的关键。

The association between systemic inflammatory markers and sarcopenia: Results from the West China Health and Aging Trend Study (WCHAT)

BackgroundIncreased evidence suggests chronic inflammation is significant in the progression of sarcopenia in older adults. In this study, we aimed to compare the level of systemic inflammation markers (White blood cells, neutrophils, lymphocytes, platelets and their derived ratios) between sarcopenic and non-sarcopenic individuals and investigate the association of these inflammatory markers with sarcopenia.MethodsThis cross-sectional study included 4224 adults (1514 men and 2710 women) from the West China Health and Aging Trend (WCHAT) study. Sarcopenia was defined according to the recommended diagnostic algorithm of the Asia Working Group for Sarcopenia (AWGS). The value of systemic inflammatory markers was based on laboratory data. Multiple logistic regression analysis was used to explore the association between inflammatory markers and sarcopenia after adjusting for covariates.ResultsAmong 4224 participants (mean age 62.3 ± 8.2 years, 64.2 % women), 814 (19.3 %) were diagnosed as sarcopenia. After adjusting for potential confounders, logistic regression analysis indicated that neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and systemic immune-inflammation index (SII) were significantly associated with sarcopenia. Participants in the highest NLR, PLR and SII value group had higher odds for sarcopenia than those in the lowest value group (OR [95 %CI]: 1.233 [1.002,1.517], 1.455 [1.177,1.799] and 1.268 [1.029,1.561], respectively).ConclusionsHigher NLR, PLR, and SII level are associated with an increased prevalence of sarcopenia in middle-aged and older adults. Since these systemic inflammatory markers are inexpensive and can be obtained easily from routine blood tests, regular follow-up of NLR, PLR and SII may be an effective strategy in sarcopenia screening and management.     

Helicobacter pylori and neurological diseases: Married by the laws of inflammation

The purpose of this paper is to review current infor-mation about the role of inflammation caused by He-licobacter pylori(H. pylori) infection in neurological diseases such as Parkinson's disease, Alzheimer's dis-ease, Guillain-Barré syndrome, multiple sclerosis, and other inflammatory diseases including ischemic stroke. Infection with H. pylori usually persists throughout life, resulting in a chronic inflammatory response with local secretion of numerous inflammatory mediators includ-ing chemokines [interleukin(IL)-8, macrophage che-motactic protein, growth-regulated oncogene(GRO)-α, chemokine(C-X-C motif) ligand 1] and cytokines [IL-1β, tumor necrosis factor-α, IL-6, IL-12, interferon-g], which can pass into the circulation and have a systemic effect. The persistence of detectable systemic and lo-cal concentrations of inflammatory mediators is likely to alter the outcome of neurological diseases. These proinflammatory factors can induce brain inflammation and the death of neurons and could eventually be asso-ciated to Parkinson's disease and also may be involved in the development of Alzheimer's disease. However,most neurological diseases are the result of a combina-tion of multiple factors, but the systemic inflammatory response is a common component and determinant in the onset, evolution, and outcome of diseases. How-ever, more studies are needed to allow understanding of the effects and mechanisms by which the inflamma-tory response generated by H. pylori infection affects neurological diseases.     

Cholinergic control of inflammation

Cytokine production is necessary to protect against pathogens and promote tissue repair, but excessive cytokine release can lead to systemic inflammation, organ failure and death. Inflammatory responses are finely regulated to effectively guard from noxious stimuli. The central nervous system interacts dynamically with the immune system to modulate inflammation through humoral and neural pathways. The effect of glucocorticoids and other humoral mediators on inflammatory responses has been studied extensively in the past decades. In contrast, neural control of inflammation has only been recently described. We summarize autonomic regulation of local and systemic inflammation through the ‘cholinergic anti‐inflammatory pathway’, a mechanism consisting of the vagus nerve and its major neurotransmitter, acetylcholine, a process dependent on the nicotinic acetylcholine receptor α7 subunit. We recapitulate additional sources of acetylcholine and their contribution to the inflammatory response, as well as acetylcholine regulation by acetylcholinesterase as a means to attenuate inflammation. We discuss potential therapeutic applications to treat diseases characterized by acute or chronic inflammation, including autoimmune diseases, and propose future research directions.     

Clinical forms of cerebrovascular diseases

The clinical manifestations of cerebrovascular diseases observed in the 7th District of Budapest between 1970 and 1976 were analyzed and the patients' further fate followed up between 1981 and 1985. It could be stated that out of the total of 1550 cases of cerebrovascular diseases registered the number of cerebral thromboses was essentially higher and that of cerebral haemorrhage markedly lower as compared to data given in the international literature. Therefore, patients with cerebrovascular diseases treated in the hospital of the 7th District were also included in the analysis. Results showed cerebral haemorrhages to occur more frequently as compared to the number of those treated in the territory; the number of thromboses was also significantly higher in these clinical patients as compared to international data. For the purpose of a more precise diagnosis the autopsy results of patients with cerebrovascular diseases who were treated and died in hospital were also reviewed. The thrombosis-cerebral haemorrhage ratio corroborated the clinically established diagnostic results. Autopsy results revealed the existence of a severe arteriosclerosis. The degree of severity in patients with a cerebrovascular disease revealed no difference as compared to other patients who died primarily because of heart diseases. It showed, however, a pronounced deviation in patients who died because of carcinoma. A more detailed investigation of these findings will be a future task.

Helminth infections and intestinal inflammation

Evidence from epidemiological studies indicates an inverse correlation between the incidence of certain immune-mediated diseases, including inflammatory bowel diseases （IBD）, and exposure to helminths. Helminth parasites are the classic inducers of Th2 responses. The Th2-polarized T cell response driven by helminth infection has been linked to the attenuation of some damaging Th1 driven inflammatory responses, preventing some Th1-mediated autoimmune diseases in the host, including experimentally induced colitis. Helminth parasites （the porcine whipworm, Trichuris suis ） have been tested for treating IBD patients, resulting in clinical amelioration of the disease. As a result, there is a great deal of interest in the research community in exploring the therapeutic use of helminth parasites for the control of immune-mediated diseases, including IBD. However, recent studies have provided evidence indicating the exacerbating effects of helminths on bacterial as well as non-infectious colitis in animal models. Therefore, a better understanding of mechanisms by which helminths modulate host immune responses in the gut may reveal novel, more effective and safer approaches to helminth-based therapy of IBD.
