Objective To retrospectively study the clinical and electrodiagnostic features in subacute combined degeneration of spinal cord (SCD)patients. Methods The clinical and electrodiagnostic recordings of all SCD patients conformed in our Neurology Department from Janu?ary 2013 to July 2015 were retrospectively reviewed. Totally 29 patients diagnosed as SCD,whom received no treatment before admitted in our hos?pital,were recruited for the study. Correlation analysis between serum level of vitamin B12(VB12),course of disease and degree of neural lesion was performed,and the electrodiagnostic features were summarized and analyzed. Results The course of disease had significant correlation with the degree of neural lesion(P=0.001),but there was no significant relevance between serum VB12 level and neural damage(P>0.05). Electrodi?agnostic examination revealed:The abnormal rate of motor nerve(15.20%)was lower than that of sensory nerve(42.75%,P<0.001)and the up?per limb nerve(27.1%)was lower than that of lower limb nerve(30.87%,P=0.578). There was no remarkable difference of abnormal rate in all kinds of nerves of motor and sensory nerve(P1=0.320,P2=0.755). In the analysis of the parameters of electromyograph,there was statistical signif?icance of the abnormal rates of compound muscle action potential(CAMP)between each motor nerve(P=0.005). There was statistical signifi?cance of the abnormal rates of CAMP and no function between each sensory nerve(all P<0.001). Conclusion The course of disease has signifi?cant correlation with the degree of neural lesion. Sensory nerve is tended to be betreffend than motor nerve. Phil.always nervous are more likely to be affected than others in motor nerve at CAMP. Tibial nerve is easier to be influenced at CAMP in sensory nerve ,and the lesion is more serious.

Objective To study the correlation between the electrophysiological features and mechanical ventilation and long?term outcome in Guil?lain?Barré syndrome(GBS)patients. Methods Electrophysiological and clinical data were retrospectively collected,and compared between venti?lated and not ventilated patients,as well as among each subtype of GBS. Results Totally 38 GBS patients were included in the study,among which 12(32%)were ventilated. The p/d CMAP ratio of the common peroneal nerve was significantly lower in ventilated group compared to not ventilated group(48.7±15.3 vs 80.8±24.0,P=0.005). AIDP was the most common subtype in ventilated patients compared with AMAN and undetermined (46%vs 0%and 9%,P=0.027). The long?term outcome score of AMAN was significantly lower than AIDP(4.3±1.3 vs 2.5±0.9,P=0.028). Conclusion Electrophysiological testing was predictive for mechanical ventilation and long?term outcome:low p/d CMAP ratio of the common pero?neal nerve was helpful for predicting mechanical ventilation,AIDP was prone to develop respiratory failure and had a worse outcome compared to AMAN.

Innate immune cells are highly represented in the tumor microenvironment,and among the most abundant of these are macrophages.However,macrophages are broadly categorized as"classically activated"pro-inflammatory M1 macrophages and"alter-natively activated"anti-inflammatory M2 macrophages,which might be too simplified to describe the various phenotypes and func-tions of tumor-associated macrophages(TAMs).Most TAMs are now reclassified into CD68+TAM,CD163+TAM,CD204+TAM,CD169+TAM,and CCL18+TAM,among others,according to the different expression of surface proteins.These surface proteins have different types of ligands and regulate different signaling pathways and cytokines.Therefore,even if these subtypes of TAMs have similar ef-fects of promoting or inhibiting tumors,the mechanisms involved and the induced clinical manifestations are different.In this paper, the effects of various phenotypes of TAMs on tumor growth,metastasis,prognosis,and clinical relevance are reviewed.

The etiology of tumors is complex and influenced by multiple factors, including the host and environmental conditions. Allergy is primarily driven by the immune response of helper T cell 2 (Th2). Research has shown that the Th2 immune response is closely related to tumors, which is specifically manifested through Th2 antibodies, allergy-related effector cells and mediators within the tumors, as well as tumor immune-related functions. This internal interaction mechanism will increase the complexity and challenges associated with the clinical diagnosis and treatment of tumors and allergy. The formation of allergic constitution is shaped by both congenital and acquired factors, and its physical state is closely linked to the occurrence and progression of allergic diseases. Therefore, this paper aims to explore the relationship between tumors and allergic reactions from the perspective of traditional Chinese medicine (TCM) constitution theory. Based on the four basic principles of the TCM constitution, including endowment inheritance theory, environment constraint theory, body-spirit composition theory, and life process theory, this exploration will focus on four aspects: genetic factors and internal disease causes, inflammatory environments and functional regulation, psychological disorders and emotional pathogenesis, as well as age structure and disease risk. Furthermore, from the perspective of constitution-disease relation of chronic disease prevention, this paper will discuss the significant importance of adjusting allergic constitution to improve both subjective symptoms and objective indicators of allergic reactions in tumor patients.
