国医大师王琦教授中医体质学理论在疼痛性疾病诊疗中的临床应用

慢性疼痛涉及临床各科的多种疾病，包括一些重大疾病和疑难疾病。中医体质学是中医学的新兴学科，其体质分类、体病相关思想以及“辨体论治”的诊疗方法已广泛应用到临床各科疾病的诊疗中。文章探讨了以中医体质学思想指导疼痛性疾病诊疗的若干理论问题，认为疼痛性疾病的发生与患者体质类型存在密切的关系。因此，在临床辨治疼痛性疾病时要考虑患者体质因素。所施方药不仅要符合病证特点，也要针对患者体质类型。并列举国医大师王琦教授辨体论治慢性前列腺炎盆腔疼痛综合征、偏头痛、过敏性头痛等疼痛性疾病的案例加以分析，以期为相关领域同仁提供参考。     

Careful assistance? Personal assistance within the family as hybridization of modern welfare policy and traditional family care

The aim of this article is to examine how different ideological perspectives on Swedish disability policy, are reflected in the experiences of disabled people and their families personal assistants. Personal assistance provided within the family can be seen as a hybridization between publicly regulated and paid work performed in the private family sphere, and thus conflicting norms and practices may coexist. In Sweden, family members of the assistant user can be employed as paid personal assistants. Many users combine personal assistance from family members with non-family assistance. Approximately 20–25% of the employed personal assistants are relatives of the assistance users. The empirical data consists of qualitative interviews with seventeen adult users and twenty-three family members employed as PAs with different types of family ties; parent-child relationships, sibling relationships and partner relationships. The findings show that family assistance could entail advantages such as personalised services, to combine instrumental and emotional assistance as well as achieving a power-balance between the parties. But there were also disadvantages, such as unwanted or enforced dependency, with a risk for both parties to be ‘locked up’ in the family. In an overall analysis, we distinguished three broad approaches towards family assistance, family as a substitute, family as a supplement and family first.     

Understanding the Influence of Nanocarrier-Mediated Brain Delivery on Therapeutic Performance Through Pharmacokinetic-Pharmacodynamic Modeling

This study aimed at evaluating how encapsulation in a regular nanocarrier (NC) (providing extended circulation time) or in a brain-targeting NC (providing prolonged circulation time and increased brain uptake) may influence the therapeutic index compared with the unformulated drug and to explore the key parameters affecting therapeutic performance using a model-based approach. Pharmacokinetic (PK) models were built with chosen PK parameters. For a scenario where central effect depends on area under the unbound brain concentration curve and peripheral toxicity relates to peak unbound plasma concentration, dose-effect and drug-side effect curves were constructed, and the therapeutic index was evaluated. Regular NC improved the therapeutic index compared with the unformulated drug due to reduced peripheral toxicity, while brain-targeting NC enhanced the therapeutic index by lowering peripheral toxicity and increasing central effect. Decreasing drug release rate or systemic clearance of NC with drug still encapsulated could increase the therapeutic index. Also, a drug with shorter half-life would therapeutically benefit more from a NC encapsulation. This work provides insights into how a NC for brain delivery should be optimized to maximize the therapeutic performance and is helpful to predict if and to what extent a drug with certain PK properties would obtain therapeutic benefit from nanoencapsulation.     

Renal Denervation for Treatment of Cardiac Arrhythmias: State of the Art and Future Directions

Renal Denervation for Treatment of Cardiac Arrhythmias . It has now been more than a quarter of a century since modulation of the sympathetic nervous system was proposed for the treatment of cardiac arrhythmias of different origins. But it has also been some time since some of the early surgical attempts have been abandoned. With the development of ablation techniques, however, new approaches and targets have been recently introduced that have revolutionized our way of thinking about sympathetic modulation. Renal nerve ablation technology is now being successfully used for the treatment of resistant hypertension, but the indication spectrum might broaden and new therapeutic options might arise in the near future. This review focuses on the possible impact of renal sympathetic system modulation on cardiac arrhythmias, the current evidence supporting this approach, and the ongoing trials of this method in electrophysiological laboratories. We will discuss the potential roles that sympathetic modulation may play in the future.     

High-definition optical magnification with digital chromoendoscopy detects gastric mucosal changes in dyspeptic-patients

BACKGROUND Accurate detection of gastric infection by Helicobacter pylori(H.pylori) and premalignant lesions are important for effective provision of treatment,preventing the development of gastric neoplasia.Optical enhancement systems with optical magnification improved the identification of mucosal superficial and vascular patterns in patients with dyspepsia.AIM To evaluate an optical enhancement system with high-definition magnification,for diagnosis of normal gastric mucosa,H.pylori-associated gastritis,and gastric atrophy.METHODS A cross-sectional,nonrandomized study from November 2015 to April 2016 performed in a single-tertiary academic center from Ecuador.Seventy-two consecutive patients with functional dyspepsia according to the Rome III criteria,were tested for H.pylori using a stool antigen test and were assigned to an Hp+group or an Hp-control group.Esophagogastroduodenoscopy with highdefinition optical magnification and digital chromoendoscopy was performed,and patients were classified into 4 groups,in accordance to the microvasculararchitecture pattern of the mucosa.Interobserver and intraobserver agreement among operators were calculated.RESULTS Of the 72 participants,35 were Hp+ and 37 were Hp-.Among 10 patients with normal mucosal histology in biopsy samples,90% had a Type I pattern of microvascular architecture by endoscopy.Among participants with type IIa and type IIb patterns,significantly more were Hp+ than Hp-(32 vs 8),and most(31 out of 40) had histological diagnoses of chronic active gastritis.Two of the three participants with a histological diagnosis of atrophy had a type III microvascular pattern.The type I pattern predicted normal mucosa,type IIa–IIb predicted H.pylori infection,and type III predicted atrophy with sensitivities of 90.0%,91.4%,and 66.7%,respectively.The intraobserver and interobserver agreements had kappa values of 0.91 and 0.89,respectively.CONCLUSION High-definition optical magnification with digital chromoendoscopy is useful for diagnosis of normal gastric mucosa and H.pylori-associated gastritis with high accuracy,but further studies are needed to determine whether endoscopic diagnosis of gastric atrophy is feasible.
