Research advances in chronic inflammatory demyelinating polyradiculoneuropathy / 中华神经科杂志

Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is a chronic autoimmune disease affecting the peripheral nervous system mediated by cellular and humoral immunity, characterized by limb weakness and sensory impairment. The main feature of CIDP by electrophysiological and pathological examinations is the demyelination of peripheral nerves. First-line treatment for CIDP includes glucocorticoids, intravenous immunoglobulins, and plasmapheresis. Some patients respond to current treatment not well and have a poor prognosis. Progress in the pathogenesis, diagnosis, and treatment of CIDP worldwide was reviewed in this article, aiming to provide references for the clinical diagnosis and treatment of CIDP.

Magnetic resonance imaging evaluation of cerebral amyloid angiopathy / 国际脑血管病杂志

Cerebral amyloid angiopathy (CAA) is a common cerebral small vessel disease, mainly caused by β-amyloid deposition on the small vessels less than 200 μm in diameter in cortex and leptomeninges. CAA is a major cause of spontaneous intracerebral hemorrhage in the elderly, especially lobar location. Early symptoms are insidious, and as the disease progress, they manifest as cerebral hemorrhage, cognitive decline, transient focal neurological episodes, cerebral infarction, epilepsy, headache, etc. MRI revealed that CAA is a disease in which bleeding and ischemia coexist, and even inflammation and immune responses are involved. MRI findings of CAA include cerebral hemorrhage, cerebral microbleeds, convexity subarachnoid hemorrhage and cortical superficial siderosis, cortical microinfarcts, CAA-associated inflammation, white matter hyperintensities, enlarged perivascular spaces, cerebral atrophy and lacune, etc. The same patient often has several of the above manifestations, and each manifestation has different specificity for the diagnosis of CAA. The rapid development of MRI technology has led to the improvement of the diagnostic level of CAA, and it is of great clinical significance to understand these imaging findings. This article reviews the MRI findings of sporadic CAA.

Animal models of Guillain-Barré syndrome / 中华神经科杂志

Guillain-Barré syndrome (GBS) is an autoimmune-mediated peripheral neuropathy. The main therapeutic strategies for GBS are intravenous immunoglobulin and plasma exchange; however, a part of patients respond not well to current strategies. The definite mechanism of GBS remains not clear and animal models are powerful tools to investigate the pathogenesis of GBS and explore new treatments. Till now, a series of animal models have been established. This paper is aimed to review these models with focus on their characteristics, advantages and disadvantages, which will be helpful for the further experimental studies of GBS.

Preliminary compilation and structural analysis of personality lexicon in southern China / 中华行为医学与脑科学杂志

Objective:To preliminarily compile the words list of personality in southern China, and structurally analyse the words with natural personality traits.Methods:A semi-structured questionnaire was used to obtain 603 valid questionnaires in six provinces in southern China, and the lexical collation, consolidation, deletion, lexicographic analysis and structural analysis were conducted.Results:(1)After three rounds of collation and merging of 8 022 natural words describing personality traits, a personality trait word list containing 136 words was obtained.(2)Econometric analysis of words according to positivity, neutrality and negativity, showed that all negative words involving moral evaluations (ruthless, vicious, evil, cunning, narrow-minded and so on) were used to describe others, while negative words describing oneself were mainly non-virtuous words (capricious, stubborn, impatient, impetuous, pessimistic and so on). (3) The proportion of desirability and virtue dimensions in the words list was highest(23.20%, 16.80%); and the proportion of desirability and extroversion in total words frequency was highest(24.39%, 19.96%).Conclusion:A personality word list containing 136 personality traits in southern China is compiled from primary sources; and a 7-factor personality structure was latent in the word list.Subjects are richer in describing the content of the vocabulary of agreeable, virtuous, pioneering, and persevering personality traits, while agreeable and extroverted personality traits are most easily perceived in interpersonal interactions.

MD-ME-SEM and MD-MF-LM allowed more thorough tissue digestion than SD-CE-LM. MD-ME-SEM resulted in the highest total recovery rate of diatom, followed by MD-MF-LM and then by SD-CE-LM (P<0.05); the recover rate of different diatom species was the highest with MD-ME-SEM, followed by MD-MF-LM and SD-CE-LM (P<0.05).</p><p><b>CONCLUSION</b>SD-CE-LM has a low recovery rate of diatoms especially for those with lengths shorter than 40 µm or densities less than 1/5. With a high recovery rate and accuracy in diatom test, MD-ME-SEM is suitable for diagnosis of suspected drowning cases. MD-MF-LM is highly efficient, sensitive and convenient for forensic diatom test.</p>
