Progress on the pathogenesis and treatment of IgG4-related disease / 药学学报

IgG4-related disease (IgG4-RD) is a newly recognized fibro-inflammatory condition of autoimmune etiology in recent twenty years, mainly manifesting as mass-forming lesions in single or multiple organs. In the past, it was often missed or misdiagnosed as inflammation or tumor. Patients may die from multiple organ failure due to end-stage fibrosis if they are not treated promptly. However, the number of clinically confirmed cases has gradually increased with the improvement of diagnostic level in recent years, and these patients have benefited greatly after receiving early treatment. Although patients generally respond well to traditional immunosuppressors including glucocorticoids and disease-modifying anti-rheumatic drugs, refractory and recurrent cases, even patients with glucocorticoid contraindication are common. Important mechanistic insights have been derived from studies of B-cell depletion therapy, but greater awareness of the pathophysiology of IgG4-RD is still badly needed to identify novel therapeutic targets. In this article, we reviewed the pathogenesis progress and promising therapy of IgG4-RD to seek better clinical management of IgG4-RD.

Essence of meridians based on neural electric field / 中国针灸

The physiological and pathological phenomenon along the running courses of meridians such as enrichment of small charged molecular, low-resistance, isotope migration, electromyography phenomenon, acoustical conductivity, thermal radiation, magnetic phenomenon and optical-electrical characteristics, etc. are explored in this article. And based on the above mentioned studies, it is concluded that as a physiological sensation along meridians, propagated sensation could only be the result of the reflection of nerve excitation. The direct stimulator of the neural electrical activities of the propagated sensation is the enrichment of charged small biological molecular at the corresponding site of the organism. The root cause of the enrichment is the unique electrophysiological mechanism and distribution discipline of the human nerve fiber, which formed an electric field of biological source for the concentration of the small molecular. Thus, it is concluded that the electric field along the running courses of meridians is an isopotential balanced line formed by multiple neural bioelectrical activities in different spaces closed to meridians.

Analysis of the risk factors of community-acquired pneumonia in patients with primary Sjogren's syndrome / 南方医科大学学报

<p><b>OBJECTIVE</b>To investigate the risk factors of community-acquired pneumonia (CAP) in patients with primary Sjogren's syndrome (pSS).</p><p><b>METHODS</b>The clinical data were collected from 121 inpatients with pSS and univariate analysis and logistic regression were conducted to analyze the risk factors of CAP.</p><p><b>RESULTS</b>The incidence of CAP in the 121 patients with pSS was 27.3%. Age, disease course, low while blood cells, low complement levels, liver and kidney dysfunction, low albumin, hyperglobulinaemia, renal tubule acidosis, interstitial lung disease (ILD) and immunosuppressive agents were closely related to CAP in these patients. Logistic regression analysis identified ILD, low complement levels and hyperglobulinemia as the risk factors for CAP in patients with pSS.</p><p><b>CONCLUSION</b>Vigorous control of pSS and minimizing the risk factors may prove effective to lower the incidence of CAP in patients with pSS.</p>
