羟氨苄青霉素引起大疱性类天疱疮样疹

Applications of nanotechnology for treatment, diagnosis, monitoring, and control of biological systems has recently been referred to as "nanomedicine" by the National Institutes of Health. Research into the rational delivery and targeting of pharmaceutical, therapeutic, and diagnostic agents is at the forefront of projects in nanomedicine. These involve the identification of precise targets (cells and receptors) related to specific clinical conditions and choice of the appropriate nanocarriers to achieve the required responses while minimizing the side effects. Mononuclear phagocytes, dendritic cells, endothelial cells, and cancers (tumor cells, as well as tumor neovasculature) are key targets. Today, nanotechnology and nanoscience approaches to particle design and formulation are beginning to expand the market for many drugs and are forming the basis for a highly profitable niche within the industry, but some predicted benefits are hyped. This article will highlight rational approaches in design and surface engineering of nanoscale vehicles and entities for site-specific drug delivery and medical imaging after parenteral administration. Potential pitfalls or side effects associated with nanoparticles are also discussed.

Nanomedicine: current status and future prospects

Guidelines and Expert Consensus documents aim to present management and recommendations based on all of the relevant evidence on a particular subject in order to help physicians to select the best possible management strategies for the individual patient, suffering from a specific condition, taking into account not only the impact on outcome, but also the risk benefit ratio of a particular diagnostic or therapeutic procedure. The ESC recommendations for guidelines production can be found on the ESC website†.

In brief, the ESC appoints experts in the field to carry out a comprehensive and critical evaluation of the use of diagnostic and therapeutic procedures and to assess the risk–benefit ratio of the therapies recommended for management and/or prevention of a given condition. The strength of evidence for or against particular procedures or treatments is weighed according to predefined scales for grading recommendations and levels of evidence, as outlined below. Once the document has been finalized and approved by all the experts involved in the Task Force, it is submitted to outside specialists for review. If necessary, the document is revised once more to be finally approved by the Committee for Practice Guidelines and selected members of the Board of the ESC.

The ESC Committee for Practice Guidelines ( CPG ) supervises and coordinates the preparation of new Guidelines and Expert Consensus Documents produced by Task Forces, expert groups, or consensus panels. The chosen experts in these writing panels are asked to provide disclosure statements of all relationships they may have, which might be perceived as real or potential conflicts of interest. These disclosure forms are kept on file at the European Heart House, headquarters of the ESC. The Committee is also responsible for the endorsement of these Guidelines and Expert Consensus Documents or statements.

 
| Classes of recommendations |
|:-------------------------- | ------------------------------------------------------------------------------------------------------------------------ |
| Class I | Evidence and/or general agreement that a given diagnostic procedure/treatment is beneficial, useful, and effective |
| Class II | Conflicting evidence and/or a divergence of opinion about the usefulness/efficacy of the treatment or procedure |
|  Class IIa | Weight of evidence/opinion is in favour of usefulness/efficacy |
|  Class IIb | Usefulness/efficacy is less well established by evidence/opinion |
| Class III | Evidence or general agreement that the treatment or procedure is not useful/effective and, in some cases, may be harmful |

Myocarditis in systemic lupus erythematosus.

Lymphedema is a complication of cancer treatment occurring in approximately 50% of patients who undergo lymph node resection. Despite its prevalence, the etiology of this disorder remains unknown. In this study, we determined the effect of soft tissue fibrosis on lymphatic function and the role of transforming growth factor (TGF)-β1 in the regulation of this response. We determined TGF-β expression patterns in matched biopsy specimens collected from lymphedematous and normal limbs of patients with secondary lymphedema. To determine the role of TGF-β in regulating tissue fibrosis, we used a mouse model of lymphedema and inhibited TGF-β function either systemically with a monoclonal antibody or locally by using a soluble, defective TGF-β receptor. Lymphedematous tissue demonstrated a nearly threefold increase in the number of cells that stained for TGF-β1. TGF-β inhibition markedly decreased tissue fibrosis, increased lymphangiogenesis, and improved lymphatic function compared with controls. In addition, inhibition of TGF-β not only decreased TGF-β expression in lymphedematous tissues, but also diminished inflammation, migration of T-helper type 2 (Th2) cells, and expression of profibrotic Th2 cytokines. Similarly, systemic depletion of T-cells markedly decreased TGF-β expression in tail tissues. Inhibition of TGF-β function promoted lymphatic regeneration, decreased tissue fibrosis, decreased chronic inflammation and Th2 cell migration, and improved lymphatic function. The use of these strategies may represent a novel means of preventing lymphedema after lymph node resection.
