Objective:To explore the efficacy of bridging therapy (BT) and direct endovascular therapy (DEVT) in patients with acute ischemic stroke induced by large vessel occlusion (LVO-AIS) within 4.5 h of onset.Methods:The clinical data of 154 patients with LVO-AIS within 4.5 h of onset, admitted to our hospital from January 2017 to July 2019, were retrospectively collected. Among them, 88 patients were hospitalized within 3 h of onset (54 accepted BT and 34 accepted DEVT); 66 patients were hospitalized within 3-4.5 h of onset (39 accepted BT and 27 accepted DEVT). The differences in clinical data and treatment efficacy between patients from the BT group and DEVT group that were hospitalized within 3 h of onset and within 3-4.5 h of onset, respectively, were compared. Multivariate Logistic regression was used to analyze the independent protective factors for favorable outcome 90 d after treatment in patients within 3.0-4.5 h of onset and within 3 h of onset, respectively.Results:(1) In patients within 3 h of onset: as compared with the DEVT group, the BT group had significantly higher improvement rate of neurological function at 24 h after treatment (41.2% vs. 70.4%) and higher percentage of patients enjoying favorable outcome 90 d after treatment (44.1% vs. 66.7%, P<0.05); multivariate Logistic regression analysis showed that BT was an independent protective factor for favorable outcome 90 d after treatment in patients within 3 h of onset ( OR=4.644, 95%CI: 1.238-12.805, P=0.041). (2) In patients within 3-4.5 h of onset: as compared with the BT group, the DEVT group had significantly higher proportion of patients having time from onset to groin puncture≤4 h, and significantly higher proportion of patients with favorable outcome 90 d after treatment ( P<0.05); multivariate Logistic regression analysis showed that the time from onset to groin puncture≤4 h was an independent protective factor for favorable outcome 90 d after treatment in patients within 3-4.5 h of onset ( OR=5.724, 95%CI: 1.192-11.676, P=0.024). Conclusion:For LVO-AIS patients, BT is the first choice in patients hospitalized in the early time window; and BT should be performed within 4 h of onset to the greatest extent for patients hospitalized in the late time window; if time from onset to groin puncture is not within 4 h, DEVT should be the first choice.

Objective To investigate the relationship between serum anticardiolipin antibody-immune globulin G (ACA-IgG),interleukin-10 (IL-10 ),IL-17 levels and intracranial large-artery atherosclerotic stenosis in patients with ischemic stroke. Methods From March 2014 to March 2015,a total of 176 consecutive patients with the first-ever ischemic stroke admitted to the Department of Neurology,Liaocheng People′s Hospital,Shandong Province,China,and performed DSA were enrolled prospectively. Seven of the patients with cardiogenic embolism,5 with moyamoya disease,8 with arteritis,2 with artery dissection,9 with autoimmune diseases or acute and chronic inflammation were excluded,21 with extracranial arterial stenosis were not enrolled,and finally 124 were enrolled in the study. According to the findings of DSA,the degrees of intracranial large artery stenosis were divided into a stenosis-free group (n = 34),a mild-stenosis group (n = 30),a moderate-stenosis group (n = 32),and a severe-stenosis group (n = 28). The differences of serum ACA-IgG,IL-10,IL-17 levels and baseline factors of the 4 groups were compared,and multivariate logistic regression analysis was used to analyze several factors that affected intracranial large-artery stenosis. Results There were no significant differences in sex,age,alcohol consumption rate,smoking rate,and incidence of hyperlipidemia among the 4 groups of patients (all P >0. 05). Compared with the stenosis-free group,there were significant differences in the incidences of hypertension and diabetes among the mild-stenosis,moderate-stenosis and severe-stenosis groups (the incidence of hypertension,80. 0% [n = 24],93. 8% [n = 30],89. 3% [n = 25]vs. 55. 9% [19 cases];χ2 = 8. 271,8. 920,and 10. 877,respectively;P = 0. 038,0. 032,and 0. 014,respectively). The incidences of diabetes were 33. 3% (n = 10),43. 8% (n = 14),60. 7% (n = 17)vs. 8. 8% (n = 3),(χ2 = 7. 960, 8. 733,and 9. 285,respectively;P = 0. 043,0. 035,and 0. 027,respectively). Incidence of diabetes of the severe-stenosis group was higher than that of the mild-stenosis group (χ2 = 9. 348,P = 0. 025). There were no significant differences in the incidences of hypertension and diabetes among other groups (all P >0. 05). There were significant differences in ACA-IgG levels (23 ± 5,39 ± 8,51 ± 9,and 65 ± 10 kU/ L);IL-10 levels (108 ± 33,85 ± 25,77 ± 21,and 62 ± 19 ng/ L),and IL-17 levels (38 ± 10,58 ± 22,63 ± 31, and 75 ± 26 ng/ L)among the stenosis-free,mild,moderate and severe-stenosis groups (F = 17. 754,9. 827, and 12. 656;respectively;all P 0. 05). The results of logistic regression analysis showed that hypertension, diabetes,ACA-IgG level,and IL-17 level were the risk factors for intracranial large-artery stenosis (OR, 3. 043,95% CI 1. 606 -5. 875,P = 0. 003;OR,2. 912,95% CI 1. 513 -5. 824,P < 0. 01;OR,1. 837,95% CI 2. 057-3. 416,P = 0. 037;OR,1. 453,95% CI 1. 346 -2. 721,P = 0. 014). Conclusion ACA-IgG and IL-17 may play an important role in the occurrence and development processes of intracranial large-artery atherosclerotic stenosis.

Objective To observe the effect of dual-task interference on postural sway and hand flexibility of patients with early Parkinson's disease (PD).Methods Twenty-tree patients with early PD and twcnty-three healthy,sex-and age-matched control subjects were examined.Postural sway was measured with an accelerometer at the centre of mass at the lower spine.Two parameters of postural sway were computed from the acceleration signals including root mean square acceleration (RMS) and jerkiness of sway (JERK).Purdue pegboard test,single-task tests and dual-task test were performed respectively to record the numbers of nails inserted with left hand,right hand and both hands within 30 seconds.Results In the usual conditions,no significant differences of postural sway parameters were found between the control group and PD group in eye open and eye closed condition.In dualtask condition,PD patients showed an increase of RMS values (eye open conditions:PD group (0.156±0.112) m/s2,control group (0.086±0.026) m/s2;eye closed conditions:PD group (0.204±0.162)m/s2,control group (0.095±0.023)m/s2) of sway acceleration,compared with control subjects (P＜0.01).These differences reached significance during cognitive task performance in eye open and eye closed with dual task.PD patients showed larger JERK values with increasing difficulty of the sway task which also reached significance during cognitive task performance(P＜0.05).The number of pegs inserted within 30 s in patients with PD (17.33±4.87)was significantly lower than that in controls (20.77±4.13) (P＜0.05).Conclusion The hand flexibility of patients with early PD obviously decrease.The balance of patients with early PD may deteriorate when their attention is diverted or reduced because of attempting to perform cognitive tasks.
