Background: and Purpose Limited evidence exists on the effectiveness of endovascular treatment (EVT) for acute posterior circulation tandem lesion (PCTL). This study aimed to explore the role of extracranial vertebral artery (VA) stenting in patients with PCTL stroke undergoing EVT. Methods: Individual patient data were pooled from the BASILAR (EVT for Acute Basilar Artery Occlusion Study) and PERSIST (Posterior Circulation Ischemic Stroke) registries. Patients with PCTLs who underwent EVT were included in the present cohort and divided into the stenting and nonstenting groups based on the placement of extracranial VA stents. The primary efficacy outcome was the modified Rankin Scale (mRS) scores at 90 days and 1 year. Safety outcomes included 24-hour symptomatic intracranial hemorrhage (sICH) and all-cause mortality at 90 days and 1 year post-surgery. Results: A combined dataset of 1,320 patients with posterior circulation artery occlusion, including 263 (19.9%) with tandem lesions, of whom 217 (median age, 65 years; 82.9% male) met the inclusion criteria for the analysis. The stenting group had 84 (38.7%) patients, while the non-stenting group had 133 (61.3%). After adjustment for the potential confounders, extracranial VA stenting was associated with favorable shifts in mRS scores at both 90 days (adjusted common odds ratio [OR], 2.30; 95% confidence interval [CI], 1.23–4.28; P<0.01) and 1 year (adjusted OR [aOR], 2.04; 95% CI [1.05–3.97]; P=0.04), along with lower rate of mortality at both 90 days (aOR, 0.45; 95% CI [0.21–0.93]; P=0.01) and 1 year (aOR, 0.36; 95% CI [0.16–0.79]; P=0.01), with no significant difference in sICH incidence (aOR, 0.35; 95% CI [0.06–1.98]; P=0.24). Conclusion Extracranial VA stenting during EVT may improve functional outcomes and reduce mortality in patients with PCTL strokes.

Background: and Purpose The optimal management of patients with acute basilar artery occlusion (BAO) is uncertain. We aimed to evaluate the safety and efficacy of endovascular thrombectomy (EVT) compared to medical management (MM) for acute BAO through a meta-analysis of randomized controlled trials (RCTs). Methods: We performed a systematic review and meta-analysis of RCTs of patients with acute BAO. We analyzed the pooled effect of EVT compared to MM on the primary outcome (modified Rankin Scale [mRS] of 0–3 at 3 months), secondary outcome (mRS 0–2 at 3 months), symptomatic intracranial hemorrhage (sICH), and 3-month mortality rates. For each study, effect sizes were computed as odds ratios (ORs) with random effects and Mantel-Haenszel weighting. Results: Four RCTs met inclusion criteria including 988 patients. There were higher odds of mRS of 0-3 at 90 days in the EVT versus MM group (45.1% vs. 29.1%, OR 1.99, 95% confidence interval [CI] 1.04–3.80; P=0.04). Patients receiving EVT had a higher sICH compared to MM (5.4% vs. 0.8%, OR 7.89, 95% CI 4.10–15.19; P<0.01). Mortality was lower in the EVT group (35.5% vs. 45.1%, OR 0.64, 95% CI 0.42–0.99; P=0.05). In an analysis of two trials with BAO patients and National Institutes of Health Stroke Scale (NIHSS) <10, there was no difference in 90-day outcomes between EVT versus MM. Conclusion In this systematic review and meta-analysis, EVT was associated with favorable outcome and decreased mortality in patients with BAO up to 24 hours from stroke symptoms compared to MM. The treatment effect in BAO patients with NIHSS <10 was less certain. Further studies are of interest to evaluate the efficacy of EVT in basilar occlusion patients with milder symptoms.

Objective:To investigate the expression and clinical significance of peptide/histidine transporter solute carrier family 15 member 4 (SLC15A4) in peripheral blood mononuclear cells (PBMCs) of patients with systemic lupus erythematosus (SLE).Methods:Fifty-five patients with SLE were divided into active SLE group and stable SLE group according to SLE disease activity index (SLEDAI) score, and 13 healthy volunteers were used as controls. The expression of SLC15A4 in PBMCs were detected by Western blot method. Moreover, the correlation between the expression of SLC15A4 and clinical and laboratory parameters of SLE patients were analyzed. The expression of SLC15a4 in the three groups was compared based on one-way analysis of variance (ANOVA), and the correlation between SLC15A4 expression level and clinical indicators was analyzed by Pearson correlation.Results:The expression levels of SLC15A4 in active SLE group, stable SLE group and healthy control group were (0.96±0.19), (0.88±0.14), (0.78±0.24), respectively. The expression level of SLC15A4 in SLE with active disease was higher than that in healthy controls ( F=4.47, P=0.015). In addition, the expression of SLC15A4 in PBMCs of SLE patients was positively correlated with the quantity of anti-double stranded DNA (anti-dsDNA) antibody, erythrocyte sedimentation rate (ESR) and systemic lupus erythematosus disease activity index (SLEDAI) ( r=0.29, P=0.031; r=0.36, P=0.007; r=0.32, P=0.017, respectively). However, the expression of SLC15A4 in PBMCs had no significant correlation with 24-h urinary protein ( r=0.45, P=0.127) and C3 ( r=0.20, P=0.133). Conclusion:SLC15A4 is involved in the pathogenesis of SLE and its expression in PBMCs of SLE patients can be used as an index to evaluate disease activity.

Objective To assess clinical efficacy of comprehensive treatment on chronic sinusitises (CRS) with neutro?phils infiltration and eosinophilic infiltration as pathological features. Methods A total of 256 CRS patients whose symp?toms were not been improved after surgery (visual analog scale>6,3 months after surgery) were included in this study. Dif?ferent comprehensive treatments were given to the patients according to the different types of cell infiltration. The visual ana?log scale (VAS), Lund-Kennedy and nasal histopathological examination were observed after treatment in patients. Results After different comprehensive treatments, the VAS and Lund-Kennedy were improved in patients with eosinophils infiltra?tion, but the number of eosinophils was not reduced. The VAS, Lund-Kennedy and the number of neutrophils were signifi?cantly improved in patients with mainly neutrophils infiltration. Conclusion According to different immune pathological characteristics, patients of CRS should be given different comprehensive treatments. There is a obvious efficacy for patients with neutrophil infiltration.

Objective Clinical studies show that the level of C-reactive protein ( CRP ) markedly increases in the acute phase of cerebral hemorrhage .However , the correlation of the CRP level with early neurological deterioration ( END) in patients with basal ganglia hemorrhage remains unclear .This study investigated the correlation between CRP and END in basal ganglia hemorrhage . Methods This study included 142 cases of basal ganglia hemorrhage diagnosed by cranial CT between Jan 2010 and Dec 2012 .END was defined as any decrease in Canadian Stroke Scale ( CSS) score≥1 point in the first 48 hours after stroke onset .We compared the baseline data between the END and non-END patients and evaluated the correlation between CRP and END by logistic regression analy -sis. Results END was found in 31 (21.8%) of the 142 patients.Univariate analysis of the END versus non-END cases showed that hyperglycemia (29.03 vs 11.71%, P=0.018), neutrophil count ([11.8 ±1.2] vs [7.8 ±7.7] ×109/L, P=0.019), CRP (P=0.001), hematoma expansion (54.83 vs 19.81%, P=0.001), hematoma volume ([23.6 ±21.9] vs [14.8 ±12.7] mL, P=0.005), and intraventricular hemorrhage (68.75 vs 28.83%, P<0.001) were significantly associated with END .Logistic regression a-nalysis indicated that the CRP level (OR=1.072, 95%CI:1.034-1.112, P=0.001), intraventricular hemorrhage (OR=4.162, 95%CI: 1.498 -11.564, P =0.006), and hematoma expansion (OR=5.297, 95%CI:1.906-14.723, P=0.001) were correlated with END in the patients during their hospital stay .ROC analysis man-ifested the predictive value of the CRP level for END in basal ganglia hemorrhage (OR=0.812, 95%CI: 0.732 -0.891, P <0.001). Conclusion The elevated level of CRP is significantly correlated with END in patients with basal ganglia hemorrhage and therefore can be re-garded as a predictive factor for this condition .

Objective To investigate the effect of progressive neurological deterioration ( PND) of cerebral watershed infarction on early prognosis. Methods The consecutive patients with cerebral watershed infarction admitted in the Department of Neurology,Jinling Hospital,Nanjing University School of Medicine and their cerebral watershed infarctions confirmed by the imaging examination from March 2009 to March 2014 were enrolled. The clinical features, laboratory indicators and imaging features of internal watershed infarction,cortical-type watershed infarction,and mixed watershed infarction were identified and analyzed. The National Institutes of Health Stroke Scale was used to score neurological deficit. The modified Rankin scale ( mRS) was used to score the prognosis of patients. Single factor analysis was used to compare the differences between the groups. At the same time,the correlation between PND and poor prognosis of cerebral watershed infarction at day 90 was analyzed by multivariable Logistic regression analysis. Results A total of 89 patients with cerebral watershed infarction were enrolled,including 43 cortical-type watershed infarctions,36 internal watershed infarctions, and 10 mixed watershed infarctions. Single factor analysis indicated that the incidences of PND of internal watershed infarction and mixed watershed infarction were significantly higher than the cortical-type watershed infarction (36. 1% [n=13],50. 0% [n=5], and 16. 3% [n=7],respectively;P=0. 018). At day 90,28 patients had poor prognosis,and mRS was (3.4±1. 0) scores at day 90. There was significant difference in the types of infarction between the patients with poor prognosis and patients with good prognosis (P<0. 05). In patients with poor prognosis, most of them were internal watershed infarctions,accounting for 50. 0% (14/28),while in patients with good prognosis,most of them were cortical-type watershed infarctions(57. 4% [35/61]). The incidence of PND in patients with poor prognosis was significantly higher than that in patients with good prognosis (57.1% [16/28] vs. 14. 8% [9/61];P<0. 05). The result of multivariate Logistic regression analysis showed that after adjustment for confounding factor, PND was independently associated with the poor prognosis of cerebral watershed infarction at day 90 (OR 6. 969,95%CI 2. 451-19. 869;P<0. 01). Conclusion Compared with the cortical-type watershed infarction, the patients with internal watershed infarction is more prone to have PND, and PND is independently correlate with the poor prognosis at day 90.
