中国古代医患关系模式初探

医患关系日益引起重视，参照现代医患关系研究相关理论，对中国古代医患关系模式进行初步研究。古代社会的医患关系同样是一种复杂和多层次的人际关系，医患模式不能一概而论。根据患者的社会地位以及所患疾病对医疗服务的需求程度和医生的社会地位及医术状况等，分为平等型、权威性、主从型，以期从传统中医的医患关系中获取价值，对目前复杂的医患关系有所借鉴。     

Follicular penetration and targeting

In the past, intercellular penetration was assumed to be the most important penetration pathway of topically applied substances. First hints that follicular penetration needs to be taken into consideration were confirmed by recent investigations, presented during the workshop "Follicular Penetration and Targeting" at the 4th Intercontinental Meeting of Hair Research Societies", in Berlin 2004. Hair follicles represent an efficient reservoir for the penetration of topically applied substances with subsequent targeting of distinct cell populations, e.g., nestin-expressing follicular bulge cells. The volume of this reservoir can be determined by differential stripping technology. The follicular penetration processes are significantly influenced by the state of the follicular infundibulum; recent experimental investigations could demonstrate that it is essential to distinguish between open and closed hair follicles. Topically applied substances can only penetrate into open hair follicle. Knowledge of follicular penetration is of high clinical relevance for functional targeting of distinct follicular regions. Human hair follicles show a hair-cycle-dependent variation of the dense neuronal and vascular network. Moreover, during hair follicle cycling with initiation of anagen, newly formed vessels occur. Thus, the potential of nestin-expressing hair follicle stem cells to form neurons and blood vessels was investigated.     

Relationship of tumorigenic malignant melanomas to dermal elastin: an expression of tumor/stromal interaction that may be related to prognosis

Malignant melanomas, which produce a large number of substances active in connective tissue modulation, must contend with the dermis to grow and propagate. We studied the morphologic interactions between tumorigenic malignant melanomas and dermal elastin. Formalin-fixed and paraffin-embedded tissues of 108 tumorigenic malignant melanomas were stained for elastic tissue with the Verhoeff-van Gieson method. Various aspects of the relationship between malignant melanoma and dermal elastin were analyzed in relation to the histologic and clinical data using univariate and multivariate analyses. Tumor thickness, mitotic rate, and the presence of elastin remnants within the tumors were found to be independent negative prognostic factors, the latter with borderline significance. Tumors with more remnants of elastin were associated with higher stage of disease and lymph node and distant metastases. Tumor infiltration between the elastic fibers in the tumor depth was associated with high Clark level, greater tumor thickness, high stage of disease, and lymph node metastases. At least partial preservation of elastic fibers in the tumor depth was a relatively good prognostic factor whereas complete absence of elastin was an adverse factor. Focal or multifocal absence of elastin in the midst of the tumors or in their depth was usually associated with lymphocytic infiltrates. We suggest that tumors with remnants of elastic fibers and/or invasion between elastic fibers in their depth may be fast growing and highly invasive. The absence of elastin within tumors and at their advancing edge may be related to the elaboration of elastin-degrading substances by melanoma cells or various inflammatory cells. Our findings indicate that the relationship between malignant melanomas and dermal connective tissue components, specifically elastin, may have prognostic significance.     

Fracture resistance and 2-body wear of 3-dimensional–printed occlusal devices

Statement of problem

Polymeric material for 3-dimensional printing can be used to fabricate occlusal devices. However, information about fracture resistance and wear is scarce.

Natriuretic peptides in unstable coronary artery disease.

Patients with unstable coronary artery disease (CAD), i.e., unstable angina or non-ST-elevation myocardial infarction, vary widely in clinical presentation, prognosis and response to treatment. To select appropriate therapy, early risk stratification has become increasingly important. This review focuses on the emerging role of natriuretic peptides in the early assessment of patients with unstable CAD. We conclude that levels of brain natriuretic peptide (BNP) and N-terminal pro-brain natriuretic peptide (NT-proBNP) are strongly associated to mortality and the risk of future congestive heart failure, and carry important prognostic information independent from previously known risk factors in unstable CAD. There are some data indicating that these markers can also be helpful in the selection of appropriate therapy in these patients but further studies are needed. Before a routine use of BNP or NT-proBNP in unstable CAD can be recommended, the cost-effectiveness of adding these new markers to the currently routine markers and their impact on selection of treatment needs further evaluation.
