Sickle cell disease (SCD) is an inherited disorder of hemoglobin in which the abnormal hemoglobin S polymerizes when deoxygenated. This polymerization of hemoglobin S not only results in hemolysis and vaso-occlusion but also precipitates inflammation, oxidative stress and chronic organ dysfunction. Oxidative stress is increasingly recognized as an important intermediate in these pathophysiological processes and is therefore an important target for therapeutic intervention. The transcription factor nuclear erythroid derived- 2 related factor 2 (Nrf2) controls the expression of anti-oxidant enzymes and is emerging as a protein whose function can be exploited with therapeutic intent. This review article is focused on triterpenoids that activate Nrf2, and their potential for reducing oxidative stress in SCD as an approach to prevent organ dysfunction associated with this disease. A brief overview of oxidative stress in the clinical context of SCD is accompanied by a discussion of several pathophysiological mechanisms contributing to oxidative stress. Finally, these mechanisms are then related to current management strategies in SCD that are either utilized currently or under evaluation. The article concludes with a perspective on the potential of the various therapeutic interventions to reduce oxidative stress and morbidity associated with SCD.

Liver transplantation is the only life-saving procedure for patients with end-stage liver disease. However, its potential benefits are hampered by many disadvantages, such as the relative shortage of donors, operative risks, and high costs. These issues have prompted the search for new alternative therapies for irreversible liver disease. Stem cell therapy, with the ability for self-renewal and potential for multilineage differentiation, is a promising alternative approach. Several studies have demonstrated that transplantation of hepatic stem/progenitor cells or hepatocyte-like cells derived from multipotent stem cells leads to donor cell-mediated repopulation of the liver and improved survival rates in experimental models of liver disease. However, a registered clinical application based on stem cell technology will take at least an additional 5 to 10 years because of some limitations; e.g. the lack of suitable cell sources and risk of teratoma formation. This review summarizes the general understanding of the therapeutic potentials of stem cells in liver disease, including the sources, mechanisms, and delivery methods of hepatic stem cells in liver regeneration, and discusses some challenges for their therapeutic application.

Diffuse cystic lung diseases are uncommon but can present a diagnostic challenge because increasing number of diseases have been associated with this presentation. Cyst in the lung is defined as a round parenchymal lucency with a well-defined thin wall (<2 mm thickness). Focal or multifocal cystic lesions include blebs, bullae, pneumatoceles, congenital cystic lesions, traumatic lesions, and several infectious processes such as coccidioidomycosis, Pneumocystis jiroveci pneumonia, and hydatid disease. “Diffuse” distribution in the lung implies involvement of all lobes. Diffuse lung involvement with cystic lesions can be seen in pulmonary lymphangioleiomyomatosis, pulmonary Langerhans’ cell histiocytosis, lymphoid interstitial pneumonia, Birt-Hogg-Dubé syndrome, amyloidosis, light chain deposition disease, honeycomb lung associated with advanced fibrosis, and several other rare causes including metastatic disease. High-resolution computed tomography of the chest helps define morphologic features of the lung lesions as well as their distribution and associated features such as intrathoracic lymphadenopathy. Correlating the tempo of the disease process and clinical context with chest imaging findings serve as important clues to defining the underlying nature of the cystic lung disease and guide diagnostic evaluation as well as management.

Pulmonary lymphangioleiomyomatosis (LAM) is a rare cystic lung disease that targets women during their reproductive years. A confident diagnosis can often be based on clinical grounds, but diagnostic certainty requires pathological analysis. Although surgical lung biopsy is considered the gold standard for obtaining tissue in patients with diffuse lung disease, it is also associated with higher morbidity and mortality than alternative, less invasive techniques. The objective of our study was to examine the utility of transbronchial biopsy in the diagnosis of LAM. We conducted two online surveys of over 1 000 LAM patients registered with the LAM Foundation who were accessible by email. Transbronchial biopsy specimens were subsequently collected and reviewed by an expert pathologist to validate the diagnosis. We found that transbronchial biopsy has a yield of approximately 60% in patients with LAM. We conclude that transbronchial biopsy may be a safe and effective method for establishing the diagnosis of LAM, obviating the need for surgical lung biopsy in more than half of LAM patients.

预防和治疗移植物抗宿主病(GVHD)最常见的方法是尝试耗竭或抑制能介导或支持同种异体反应的T细胞;但这会导致T细胞受体功能缺陷,并因此对感染和肿瘤复发高度敏感。通常通过广泛使用反应性抗体来实现耗竭,而功能损坏通常在使用需长期给药(一般为6个月或更长时间)且具有明显副作用的药物后发生,这种药物可能不会导致供体T细胞对耐调节方案且携带宿主同种抗原的细胞产生耐受性(即无反应性)。随着对免疫系统稳态认识的深化,我们已能鉴定和表征具有免疫调节功能的细胞群。虽然这种细胞群通常比较少见,但可通过分离和扩增此类细胞的方法在移植后晚期增补供体移植物或进行输注,来抑制GVHD。本文将探讨GVHD模型中的生物学和临床前概念验证,以及现已发展至临床测试阶段的免疫调节细胞疗法对GVHD的疗效。
