Objective To investigate the expression of inducible co-stimulator (ICOS) on T lymphocytes in peripheral blood from the patients with systemic lupus erythematosus (SLE). Methods Two-color immunofluorescent staining and flow cytometric assay were used to analyze the level of ICOS expression on T lymphocytes in peripheral blood from 33 SLE patients and 16 healthy volunteers. The data of systemic lupus erythematosus diseases activity index (SLEDAI) in SLE patients were also collected. Results The level of ICOS expression on T cells from active SLE group was markedly higher than that in the control group and the inactive SLE group (P 0.05). However, a positive correlation between the expression level of ICOS and the SLEDAI score was found in both active SLE group and inactive SLE group(r = 0.711,P = 0.001?r = 0.561,P = 0.03). Conclusions The expression of ICOS on T cell in peripheral blood from active SLE is increased, which might play a role in the pathogenesis of SLE.

The expression of inducible co-stimulator (ICOS) in peripheral blood T lymphocytes from the patients with systemic lupus erythematosus (SLE) and the role in the pathogenesis of SLE was investigated. By using two-color immunofluorescent staining and flow cytometric assay, the expression levels of ICOS in peripheal blood T lymphocytes from 33 patients with SLE and 16 healthy volunteers were detected. SLE diseases activity index (SLEDAI) of the patients with SLE was used to evaluate the disease activity. The correlation between the ICOS expression and SLEDAI was analyzed among the groups. The results showed that the expression levels of ICOS in T lymphocytes in active SLE group was markedly higher than those in the control and inactive SLE groups (both P< 0.01). There was no significant difference in the expression levels of ICOS between the inactive SLE and the control groups (P>0.05). In active SLE and inactive SLE groups, positive linear correlation was found between the levels of the ICOS expression in T lymphocytes and SLEDAI (r=0. 711, P=0.001; r=0.561, P=0.03). It was suggested that the expression of ICOS in peripheral blood T lymphocytes from the patients with active SLE was up-regulated and and ICOS might be related to the pathogenesis of SLE.

Anti-Sry-like high mobility group box (SOX) 1 antibodies (abs) are partly characterized onconeural autoantibodies (autoabs) due to their correlation with neoplastic diseases. AntiSOX1 abs are associated with various clinical manifestations, including Lambert-Eaton myasthenic syndrome (LEMS) and paraneoplastic cerebellar degeneration (PCD). However, the clinical characteristics of patients with anti-SOX1 abs have not been described in detail. This review systematically explores the reported patients with anti-SOX1 abs and analyzes these cases for demographic characteristics, clinical features, coexisting neuronal autoabs, neuroimaging findings, treatment, and clinical outcomes. In addition, considering that PCD is the most common paraneoplastic neurological syndrome and that the association between PCD and anti-SOX1 abs remains unclear, we focus on the presence of autoabs in relation to PCD and associated tumors. PCD-associated autoabs include various intracellular autoabs (e.g., anti-Hu, anti-Yo, anti-Ri, and anti-SOX1) and cell-surface autoabs (anti-P/Q-type voltage-gated calcium channel). Commonly involved tumors in PCD are small-cell lung cancer (SCLC), gynecological, and breast tumors. LEMS is the most common clinical symptom in patients with antiSOX1 abs, followed by PCD, and multiple neuronal autoabs coexist in 47.1% of these patients.SCLC is still the predominant tumor in patients with anti-SOX1 abs, while non-SCLC is uncommon. No consistent imaging feature is found in patients with anti-SOX1 abs, and there is no consensus on either the therapy choice or therapeutic efficacy. In conclusion, the presence of anti-SOX1 abs alone is a potential predictor of an uncommon paraneoplastic neurological disorder, usually occurring in the setting of LEMS, PCD, and SCLC. The detection of anti-SOX1 abs contributes to an early diagnosis of underlying tumors, given the diversity of clinical symptoms and the absence of characteristic neuroimaging features.

Objective:To investigate the impact of group-based rehabilitation exercise on motor and non-movement symptoms of Parkinson's disease(PD).Methods:A total of 88 patients from out-patient and in-patient services at our hospital were randomly assigned to an early exercise group(E-EG), a late exercise group(L-EG), and a control group(CG)using a randomized delayed-start design.Patients in the E-EG carried out a rigorous, formal group exercise program, one hour per session, twice per week, for 18 months(May 2018-November 2019). Patients in the L-EG took part in the exercise program in the final 6-12 months of the study.We assessed outcomes using the Unified Parkinson's Disease Rating Scale(UPDRS), Parkinson's disease questionnaire-39(PDQ-39 Q), trail-making test part A & B, nine-hole peg test(9-HPT), 30 second sit to stand test(30s SST), 10 m walk test(10 m W), mini-balance evaluation systems test(Mini-BEST), Fullerton Advanced Balance(FAB)Scale and time up and go(TUG)test.Results:Compared with pre-exercise levels, patients with PD in the E-EG had lower performance in UPDRS(17.5±8.3 vs.20.0±8.6, t=-2.2, P=0.02)and lower performance in PDQ-39(27.2±2.1 vs.29.0±9.8, t=-2.6, P=0.001)after exercise.Moreover, compared with pre-exercise levels, patients with PD in the E-EG showed decreased post-exercise performance in trail-making test part B(114.2±25.5 vs.129.8±28.4, t=-2.3, P=0.02)and in 9-HPT(33.7±7.3 vs.39.6±9.3, t=-2.6, P=0.001). Conclusions:The practice of group-based rehabilitation exercise can improve movement abilities and quality of life in PD patients, especially if implemented early.Targeted rehabilitation exercise should be taken as part of the treatment strategy for PD patients as early as possible to deliver the best benefits.
