Abstract

AIM: To explore the neuro-ophthalmological characteristics of acute macular neuroretinopathy(AMN)after SARS-CoV-2 infection.METHODS: A total of 8 patients(14 eyes), including 6 females and 2 males, who were diagnosed with AMN in the neuro-ophthalmology department of Xi'an No.1 Hospital(The First Affiliated Hospital of Northwest University)from December 27, 2022 to February 1, 2023 were included in the study. All patients had a history of SARS-CoV-2 infection before the disease, and the results of best corrected visual acuity(BCVA), non-contact indirect intraocular pressure measurement, fundus color photography, near infrared(IR), spectral-domain optical coherence tomography(SD-OCT), OCT angiography(OCTA), fundus fluorescein angiography(FFA), indocyanine green angiography(ICGA), visual field, visual evoked potential(VEP), and electroretinogram(ERG)were collected. Furthermore, the neuro-opthalmology characteristics of the included patients were analyzed and summarized.RESULTS: The included 8 patients aged from 20 to 43, with an average age of(30±6.63)years old. The patients had a history of SARS-CoV-2 infection 3 to 11(mean 5±3.51)d before the disease, and 6 out of 8 patients developed visual symptoms within 5 d of infection with SARS-CoV-2, with manifestated with decreased vision or visual scotoma. The visual acuity varied from 0.08 to 1.0, with visual field defect characterized by central, paracentral or peripheral scotoma. VEP showed prolongation latency of P100 or P2, and ERG revealed impaired function of retinal photoreceptor cell. In the early stage of the disease, the size and shape of early visual acuity, visual field, and extraretinal lesions in patients with AMN associated with SARS-CoV-2 infection may not match, and the lower the visual acuity, the later the VEP peaks.CONCLUSION: The neuro-ophthalmic features of SARS-CoV-2 infection-associated AMN require the attention of clinicians. In addition to multi-mode fundus imaging, clinicians should use a variety of methods to comprehensively evaluate visual function and prognosis of patients.

Abstract

目的 探讨动脉内溶栓（intra-arterial thrombolysis，IAT）治疗视网膜中央动脉阻塞（central retinal artery occlusion，CRAO）患者的临床特征及功能性视觉恢复情况。 方法 纳入2018年1月—2023年8月西北大学附属第一医院神经内科和神经眼科连续收治的非动脉炎性CRAO患者，根据入院后是否进行IAT治疗分为IAT组和非IAT组。功能性视觉定义为 视力≥20/100。比较分析两组患者的临床特征和不同时间段（入院、出院时和出院1个月时）功能性视觉恢复情况。 结果 共纳入131例（131只眼）非动脉炎性CRAO患者，男性93例（71.0%），平均年龄为（61.6±12.6）岁， 其中IAT组57例（43.5%），非IAT组74例（56.5%）。与非IAT组患者相比，IAT组患者年龄更低[（58.4±12.5）岁 vs.（64.1±12.2）岁，P=0.011]、合并卒中病史者比例更低[10（17.5%）vs. 25（33.8%）， P=0.037]、发病至就诊时间更短[10.0（6.0～24.0）h vs. 55.0（20.2～162.0）h，P＜0.001]、醒后发病者比例更高[26（45.6%）vs. 15（20.3%），P=0.002]和患侧颈内动脉血管状态更佳（无狭窄∶轻度狭窄∶中-重度狭窄∶闭塞=41∶7∶7∶2 vs. 32∶11∶21∶10，P=0.006）。IAT组患者出院1个月时功能性视觉比例较非IAT组患者更高[25（43.9%）vs. 18（24.3%），P=0.018]，而入院和出院时差异无统计学意义 （P＞0.05）。多因素logistic回归分析显示，IAT组患者出院1个月时的功能性视觉较非IAT组患者显著改善（OR 3.24，95%CI 1.08～9.69，P=0.036）。IAT组患者术中发生眼动脉痉挛2例（3.5%）、穿刺部位皮肤出血2例（3.5%）和新发脑栓塞（均为无症状性栓塞）事件4例（7.0%）。 结论 是否进行IAT治疗的CRAO患者部分临床特征存在差异，IAT治疗可显著提高CRAO患者出院1个月时的功能性视觉，且手术安全性较好。提示临床医师需重视CRAO患者的IAT治疗，以期改善患者的视觉功能。 Abstract: Objective To investigate the clinical characteristics and functional visual recovery of patients with central retinal artery occlusion (CRAO) treated with intra-arterial thrombolysis (IAT). Methods The non-arteriotic CRAO patients admitted to the Department of Neurology and Neuro-ophthalmology of the First Affiliated Hospital of Northwest University from January 2018 to August 2023 were included. They were divided into IAT group and non-IAT group according to whether IAT was performed after admission. Functional vision is defined as visual acuity≥20/100. The clinical features and functional visual recovery at different time periods (admission, discharge and 1 month after discharge) were compared and analyzed between the two groups. Results A total of 131 patients (131 eyes) with non-arteriotic CRAO were included, including 93 males (71.0%) with a mean age of (61.6±12.6) years. There were 57 patients (43.5%) in IAT group and 74 patients (56.5%) in non-IAT group. Compared with patients in non-IAT group, patients in IAT group had younger age [(58.4±12.5) years vs. (64.1±12.2) years, P=0.011], lower proportion of stroke history [10 (17.5%) vs. 25 (33.8%), P=0.037], shorter time from onset to visit [10.0 (6.0-24.0) h vs. 55.0 (20.2-162.0) h, P0.05). Multivariate logistic regression analysis showed that the functional vision of CRAO patients in the IAT group at 1 month after discharge was significantly improved compared with those in the non-IAT group (OR 3.24, 95%CI 1.08-9.69, P=0.036). In the IAT group, ophthalmic artery spasm occurred in 2 cases (3.5%), skin bleeding at the puncture site in 2 cases (3.5%), and new cerebral embolism (all asymptomatic embolism) occurred in 4 cases (7.0%). Conclusions Some clinical features of CRAO patients who were treated with or without IAT were different. IAT can significantly improve the functional vision of CRAO patients at 1 month after discharge, and the surgical safety is good. This suggests that clinicians should pay more attention to IAT in CRAO patients in order to improve their visual function.

Abstract

Introduction: The triglyceride-glucose (TyG) index is reported to be related to poor functional outcomes and all-cause mortality post-stroke. However, the association between TyG index and recurrent stroke after acute ischemic stroke (AIS) has not been well described. We aimed to identify whether the TyG index was associated with 1-year recurrent stroke after AIS. Methods: Baseline patient information was collected at admission, and the TyG index was calculated. Recurrent stroke events were followed up at 1, 3, 6, and 12 months after diagnosis. We then examined the association between the TyG index and risk of 1-year recurrent stroke using multivariable Cox regression models and restricted cubic spline analyses. Results: Among 2,288 participants, the mean TyG index was 8.8 ± 0.7. Those in the fourth quartile (Q4) demonstrated higher recurrent stroke risk than those in Q1 (adjusted hazard ratio [HR] = 1.63; 95% confidence interval [CI], 0.98–2.72; p = 0.059). Subgroup analysis revealed a sex-specific association between TyG index and recurrent stroke (p for interaction = 0.022). Additionally, restricted cubic splines analyses showed a nonlinear association between the TyG index and 1-year recurrent stroke. In females, patients in the Q4 had a 2.95-fold increased recurrent stroke risk than did patients in the Q1 (adjusted HR = 2.95; 95% CI: 1.09–7.94; p = 0.032); the risk increased when the TyG index was >8.73. However, no significant correlation was observed in males. Conclusion: A nonlinear association was found between the TyG index and 1-year recurrent stroke risk. Subsequently, a high TyG index could predict an increased 1-year recurrent stroke risk in female AIS patients. [ABSTRACT FROM AUTHOR]

Abstract

Background: Stroke is an important cause of death and disability worldwide, ranking second in the cause of death, and it is thought to be related to genetic factors. The purpose of our study is to investigate the association between CASZ1, WNT2B and PTPRG single nucleotide polymorphisms (SNPs) and stroke risk in the Chinese population. Methods: We recruited 1418 volunteers, comprised of 710 stroke cases and 708 controls in this study. We used MassARRAY iPLEX GOLD method to genotype the three SNPs on CASZ1, WNT2B and PTPRG. Logistic regression was used to analyse the association between these SNPs and stroke, and odds ratios (ORs) and 95% confidence intervals (CIs) were then calculated. What's more, the interactions among SNPs were predicted by multi‐factor dimensionality reduction (MDR) analysis. Results: This research demonstrated that CASZ1 rs880315 and PTPRG rs704341 were associated with reduced stroke susceptibility. More precisely, CASZ1 rs880315 was associated with reduced stroke susceptibility in people aged ≤64 years and women. PTPRG rs704341 was associated with reduced stroke susceptibility in people aged >64 years, women, non‐smokers and non‐drinkers. Conversely, WNT2B rs12037987 was related to elevated stroke susceptibility in people aged >64 years, women and non‐smokers. In addition, CASZ1 rs880315, WNT2B rs12037987 and PTPRG rs704341 had a strong redundancy relationship. Conclusion: Our study concludes that CASZ1 rs880315, WNT2B rs12037987 and PTPRG rs704341 are associated with stroke, and the study provides a basis for assessing genetic variants associated with stroke risk in the Han Chinese population.

Abstract

S100B is an essential biomarker in the early diagnosis and treatment monitoring of brain injury. However, the traditional clinical diagnostic assay for S100B detection requires a complex operation or large equipment, which limits its application for rapid point-of-care tests (POCT). This study aimed to establish a lateral-flow immunoassay (LFIA) strip test system for S100B determination. PSS-MA-GoldMag nanoparticles were conjugated with anti-S100B antibodies as probes. Using this antibody-nanoparticle composite, an LFIA system based on magnetic quantification was established for S100B detection. For the evaluation of the performance of this LFIA system in clinical practice, 216 clinical samples were assayed using the LFIA test system and a commercial ECLI kit. Using the LFIA system, reliable results could be obtained in 30 min with a detection limit of 0.05 ng mL−1. The coefficient of variation (CV) was <13.8% and <14.03% for intra- and inter-assay precision, respectively. The recoveries were between 95.1 and 107.3%. The relative deviation of the interference experiments was <10%. In the analysis of clinical samples, the result indicated that the sera level of S100B in the detection group did not correlate with gender (p = 0.564 > 0.05) or age (p = 0.083 > 0.05). There is a good correlation between the novel method and the Elecsys®, with a determination coefficient of R2 0.9566, p > 0.05. The Bland–Altman analysis between the two ways shows that the 95% confidence bands between the two methods in measuring S100B were −0.27 ng mL−1 to +0.29 ng mL−1 with a mean difference of +0.006 ng mL−1. These results indicated that the novel LFIA system could be a simple, rapid, convenient, and accurate method for S100B determination. [ABSTRACT FROM AUTHOR]

Abstract

BackgroundAlkaline phosphatase (ALP) is associated with an increased risk of cardiovascular events and is closely related to adverse outcomes after stroke. However, the regional investigation into the associations of ALP with acute stroke (AS) outcomes is limited. This study aimed to identify the association between serum ALP levels and clinical outcomes 3 months after AS in the Xi'an district of China.MethodsWe enrolled all patients with AS from 4 hospitals in the Xi'an district from January to December 2015. ALP levels and related patient information were collected at admission, and the events of stroke outcomes were followed up 1 and 3 months after diagnosis. ALP levels were analyzed as continuous variables and quartiles (Q1–Q4). The outcomes included all-cause mortality, recurrent stroke, and poor functional outcomes (modified Rankin Scale score of 3–6) within 3 months. A multivariate logistic regression and interaction analyses were performed to evaluate the independent association between serum ALP level and 3-month stroke outcomes.ResultsOverall, 2,799 patients with AS were enrolled in this study. The mean age was 63.9 ± 12.5 years. In the Q4 (≥93.0 U/L) group, the incidences of all-cause mortality, recurrent stroke, and poor functional outcomes were 7.8, 2.7, and 24.9%, respectively. After being adjusted for confounding variables, patients in Q4 (≥93.0 U/L) were related to an increased risk of all-cause mortality [odds ratio (OR) = 2.17, 95% CI: 1.19–3.96; P = 0.011] and patients in Q3 (76.8–92.9 U/L) were related to a lower risk of recurrent stroke (OR = 0.37, 95% CI: 0.14–0.97; P = 0.043) at the 3-month time point, compared to those in Q2 (63.0–76.7 U/L). The optimal range of ALP for all-cause mortality was seen in Q2, with a nadir level of 70 U/L. However, differences were statistically insignificant between ALP levels and poor functional outcomes (P > 0.05). Moreover, there was no significant interaction between ALP levels and age, gender, drinking status, smoking status, or pneumonia (P > 0.05) for all outcomes.ConclusionNon-linear associations were observed between serum ALP levels and 3-month outcomes in patients with AS. It might be beneficial to reduce the risk of all-cause mortality and recurrent stroke by maintaining ALP at optimal ranges.

Abstract

A nine-year-old boy manifested with headache, progressive mild cognitive decline and hemiparesis, but without clinical epileptic seizures (with abnormal EEG waves). Brain magnetic resonance imaging (MRI) showed bilateral cortical lesions mainly on the right hemisphere, and new lesions developed in frontal, parietal, occipital and temporal lobes around the old lesions presenting as a lace-like or ring-like enhancement in T1 with contrast over a disease course of five years. A suspected diagnosis of primary angiitis of the central nervous system was initially considered. Treated with high-dose corticosteroids, intravenous immunoglobulins and monthly pulse cyclophosphamide, his symptoms worsened with the intracranial lesion progression. Brain biopsy of the right frontal lobe was performed nearly five years after onset; prominent neuronal loss, a microglial nodule, as well as parenchymal and perivascular lymphocytic infiltrate within the cortex were found, which coincided with RE pathology changes. Encouragingly, after a regimen of rituximab, lesions on the follow-up brain MRI tended to be stable. Apparently, it was immune-mediated, but did not strictly fit any known disease entity, although it was similar to RE. We summarize this unique case, including clinical characteristics, imaging and pathology findings. We also discuss the diagnosis and treatment, focusing on comparison to RE as well as other possible neurological diseases. [ABSTRACT FROM AUTHOR]

42. Psoralidin protects against cerebral hypoxia/reoxygenation injury: Role of GAS6/Axl signaling.

Author

Abstract

Psoralidin (PSO) is a natural phenolic coumarin extracted from the seeds of Psoralea corylifolia L. Growing preclinical evidence indicates that PSO has anti‐inflammatory, anti‐vitiligo, anti‐bacterial, and anti‐viral effects. Growth arrest‐specific gene 6 (GAS6) and its receptor, Axl, modulate cellular oxidative stress, apoptosis, survival, proliferation, migration, and mitogenesis. Notably, the neuroprotective role of the GAS6/Axl axis has been identified in previous studies. We hypothesize that PSO ameliorates cerebral hypoxia/reoxygenation (HR) injury via activating the GAS6/Axl signaling. We first confirmed that PSO was not toxic to the cells and upregulated GAS6 and Axl expression after HR injury. Moreover, PSO exerted a marked neuroprotective effect against HR injury, represented by restored cell viability and cell morphology, decreased lactate dehydrogenase (LDH) release, and reactive oxygen species (ROS) generation. Furthermore, PSO pretreatment also elevated the levels of nuclear factor‐related factor 2 (Nrf‐2), NAD(P)H dehydrogenase quinone‐1 (NQO1), heme oxygenase‐1 (HO‐1), silent information regulator 1 (SIRT1), peroxisome proliferator‐activated receptor coactivator 1α (PGC‐1α), nuclear respiratory factor 1 (NRF1), uncoupling protein 2 (UCP2), and B‐cell lymphoma 2 (BCl2) both in the condition of baseline and HR injury. However, GAS6 siRNA or Axl siRNA inhibited the neuroprotective effects of PSO. Our findings suggest that PSO pretreatment attenuated HR‐induced oxidative stress, apoptosis, and mitochondrial dysfunction in neuroblastoma cells through the activation of GAS6/Axl signaling.

Abstract

Abstract Background There are a variety of treatment options for Bell's palsy. Evidence from randomized controlled trials indicates corticosteroids can be used as a proven therapy for Bell's palsy. Acupuncture is one of the most commonly used methods to treat Bell's palsy in China. Recent studies suggest that staging treatment is more suitable for Bell's palsy, according to different path-stages of this disease. The aim of this study is to compare the effects of prednisolone and staging acupuncture in the recovery of the affected facial nerve, and to verify whether prednisolone in combination with staging acupuncture is more effective than prednisolone alone for Bell's palsy in a large number of patients. Methods/Design In this article, we report the design and protocol of a large sample multi-center randomized controlled trial to treat Bell's palsy with prednisolone and/or acupuncture. In total, 1200 patients aged 18 to 75 years within 72 h of onset of acute, unilateral, peripheral facial palsy will be assessed. There are six treatment groups, with four treated according to different path-stages and two not. These patients are randomly assigned to be in one of the following six treatment groups, i.e. 1) placebo prednisolone group, 2) prednisolone group, 3) placebo prednisolone plus acute stage acupuncture group, 4) prednisolone plus acute stage acupuncture group, 5) placebo prednisolone plus resting stage acupuncture group, 6) prednisolone plus resting stage acupuncture group. The primary outcome is the time to complete recovery of facial function, assessed by Sunnybrook system and House-Brackmann scale. The secondary outcomes include the incidence of ipsilateral pain in the early stage of palsy (and the duration of this pain), the proportion of patients with severe pain, the occurrence of synkinesis, facial spasm or contracture, and the severity of residual facial symptoms during the study period. Discussion The result of this trial will assess the efficacy of using prednisolone and staging acupuncture to treat Bell's palsy, and to determine a best combination therapy with prednisolone and acupuncture for treating Bell's palsy.

Abstract

Although the opening of Tianjin was forced, it actually accelerated the connection of Tianjin and its hinterland with the international market. The opening brought great changes to the structure of agriculture, animal husbandry, and industry and commerce in the hinterland; encouraged the development of market orientation and international orientation in the hinterland’s economy; and greatly improved the occupational organization and income of most farmers and herdsmen. The opening resulted in great progress for the whole modern economy of the hinterland and thereby provided an exemplary case for the study of problems related to the economic modernization process of China.
