中药材X-射线衍射图谱研究

为探讨中药材道地性的客观规律,以期建立相应的评估指标系统,本文选择常用中药材茜草类、贝母类、山药类三组样品,应用X-射线粉末衍射法进行图谱分析,获得了可用于标识中药材的衍射图形几何拓扑规律与图谱特征标记峰,由此观察到:不同产地茜草样品的相似性及其与欧茜草的差别;同属不同种贝母样品的相似性与差异;不同产地山药样品的相似性及与伪品的区别。本文结果预示着这一方法在揭示中药材道地性客观规律方面的广阔应用前景。     

Health-related quality of life in autoimmune hepatitis

Autoimmune hepatitis (AIH) is a severe chronic autoimmune disease and has a significant impact on the patient’s quality of life, in particular regarding psychological problems such as anxiety and depression. Consistent evidence on which patient-related, disease-related or physician-related factors cause health-related quality of life (HRQoL) impairment in patients with AIH is lacking. Current studies on HRQoL in AIH are mainly single-centered, comprising small numbers of patients, and difficult to compare because of the use of different questionnaires, patient populations, and cutoff values. Literature in the pediatric field is sparse, but suggests that children/adolescents with AIH have a lower HRQoL. Knowledge of HRQoL and cohesive factors in AIH are important to improve healthcare for AIH patients, for example by developing an AIH-specific chronic healthcare model. By recognizing the importance of quality of life beyond the concept of biochemical and histological remission, clinicians allow us to seek enhancements and possible interventions in the management of AIH, aiming at improved health.
