Abstract
BACKGROUND Immunotherapy has been shown to reduce relapses in patients with myelin oligodendrocyte glycoprotein antibody-associated disorder (MOG-AD); however, the superiority of specific treatments remains unclear. AIM: To identify the efficacy and tolerability of different treatments for MOG-AD. METHODS Systematic search in Pubmed, Embase, Web of Science, and Cochrane Library databases from inception to March 1, 2021, were performed. Published articles including patients with MOG-AD and reporting the efficacy or tolerability of two or more types of treatment in preventing relapses were included. Reported outcomes including incidence of relapse, annualized relapse rate (ARR), and side effects were extracted. Network meta-analysis with a random-effect model within a Bayesian framework was conducted. Between group comparisons were estimated using Odds ratio (OR) or mean difference (MD) with 95% credible intervals (CrI). RESULTS Twelve studies that compared the efficacy of 10 different treatments in preventing MOG-AD relapse, including 735 patients, were analyzed. In terms of incidence of relapse, intravenous immunoglobulins (IVIG), oral corticosteroids (OC), mycophenolate mofetil (MMF), azathioprine (AZA), and rituximab (RTX) were all significantly more effective than no treatment (ORs ranged from 0.075 to 0.34). On the contrary, disease-modifying therapy (DMT) (OR=1.3, 95% CrI: 0.31 to 5.0) and tacrolimus (TAC) (OR=5.9, 95% CrI: 0.19 to 310) would increase the incidence of relapse. Compared with DMT, IVIG significantly reduced the ARR (MD=-0.85, 95% CrI: -1.7 to -0.098). AZA, MMF, OC and RTX showed a trend to decrease ARR, but those results did not reach significant differences. The combined results for relapse rate and adverse events, as well as ARR and adverse events showed that IVIG and OC were the most effective and tolerable therapies. CONCLUSIONS Whilst DMT should be avoided, IVIG and OC may be suited as first-line therapies for patients with MOG-AD. RTX, MMF, and AZA present suitable alternatives.

Abstract
OBJECTIVE To summarise evidence of the effects of blood pressure (BP)-lowering interventions after acute spontaneous intracerebral haemorrhage (ICH). METHODS A prespecified systematic review of the Cochrane Central Register of Controlled Trials, EMBASE and MEDLINE databases from inception to 23 June 2020 to identify randomised controlled trials that compared active BP-lowering agents versus placebo or intensive versus guideline BP-lowering targets for adults <7 days after ICH onset. The primary outcome was function (distribution of scores on the modified Rankin scale) 90 days after randomisation. Radiological outcomes were absolute (>6 mL) and proportional (>33%) haematoma growth at 24 hours. Meta-analysis used a one-stage approach, adjusted using generalised linear mixed models with prespecified covariables and trial as a random effect. RESULTS Of 7094 studies identified, 50 trials involving 11 494 patients were eligible and 16 (32.0%) shared patient-level data from 6221 (54.1%) patients (mean age 64.2 [SD 12.9], 2266 [36.4%] females) with a median time from symptom onset to randomisation of 3.8 hours (IQR 2.6-5.3). Active/intensive BP-lowering interventions had no effect on the primary outcome compared with placebo/guideline treatment (adjusted OR for unfavourable shift in modified Rankin scale scores: 0.97, 95% CI 0.88 to 1.06; p=0.50), but there was significant heterogeneity by strategy (p(interaction)=0.031) and agent (p(interaction)<0.0001). Active/intensive BP-lowering interventions clearly reduced absolute (>6 ml, adjusted OR 0.75, 95%CI 0.60 to 0.92; p=0.0077) and relative (≥33%, adjusted OR 0.82, 95%CI 0.68 to 0.99; p=0.034) haematoma growth. INTERPRETATION Overall, a broad range of interventions to lower BP within 7 days of ICH onset had no overall benefit on functional recovery, despite reducing bleeding. The treatment effect appeared to vary according to strategy and agent. PROSPERO REGISTRATION NUMBER CRD42019141136.

Abstract
OBJECTIVE To explore the effect of individualized blood pressure (BP)-lowering treatment on the outcomes of elderly patients with severe intracerebral hemorrhage (ICH). METHODS We performed an exploratory analysis of Controlling Hypertension After Severe Cerebrovascular Event (CHASE) trial, which was a multicenter, randomized, controlled clinical trial. Patients with severe ischemic or hemorrhagic stroke (defined as GCS ≤ 12 or NIHSS ≥ 11) were randomized into individualized versus standard BP-lowering treatment in CHASE trial. In this exploratory analysis, patients with severe ICH were included. The primary outcome was the percentage of patients with 90-day functional independence defined as modified Rankin Scale (mRS) ≤2. RESULTS We included 242 patients with severe ICH in the present analysis, consisting of 142 patients aged <65 years and 100 patients aged ≥65 years. There were significant differences between patients aged ≥65 years and <65 years in the proportion of functional independence (47.9% vs. 15.0%, P < 0.001) and good outcome (73.9% vs. 50.0%, P < 0.001) at day 90. In patients aged ≥65 years, the adjusted individualized BP-lowering treatment had an unequivocal effect on the functional independence at day 90 (21.6% vs. 8.2%, odds ratio [OR]: 4.309, 95% confidence interval [CI]: 1.040-17.859, P = 0.044) and improved the neurological deficits at discharge (∆ NIHSS ≥ 4: 64.7% vs. 34.7%, OR: 4.300, 95% CI: 1.599-11.563, P = 0.004). INTERPRETATION Compared with the younger counterparts, the elderly patients (≥65 years) with acute severe ICH might benefit more from individualized BP-lowering treatment.

Abstract
INTRODUCTION Reports vary on how sex influences the management and outcome from acute intracerebral haemorrhage. We aimed to quantify sex disparities in clinical characteristics, management, including response to blood pressure lowering treatment, and outcomes in patients with acute intracerebral haemorrhage, through interrogation of two large clinical trial databases. PATIENTS AND METHODS Post-hoc pooled analysis of the Intensive Blood Pressure Reduction in Acute Cerebral Haemorrhage trials 1 and 2, where patients with a hypertensive response (systolic, 150-220 mmHg) after spontaneous intracerebral haemorrhage (<6 h) were randomised to intensive (target <140 mmHg <1 h) or guideline-recommended (<180 mmHg) blood pressure lowering treatment. The interaction of sex on early haematoma growth (24 h), death or major disability (modified Rankin scale scores 3-6 at 90 days), and effect of randomised treatment were determined in multivariable logistic regression models adjusted for baseline confounding variables. RESULTS In 3233 participants, 1191 (37%) were women who were significantly older, had higher baseline National Institutes of Health Stroke Scale scores and smaller haematoma volumes compared to men. Men had higher three-month mortality (odds ratio 1.48, 95% confidence interval 1.10-2.00); however, there was no difference between women and men in the combined endpoint of death or major disability. There were no significant sex differences on mean haematoma growth or effect of randomised blood pressure lowering treatment. DISCUSSION Men included in the Intensive Blood Pressure Reduction in Acute Cerebral Haemorrhage trials had more comorbidities, larger baseline haematoma volumes and higher mortality after adjustment for age, as compared with women. CONCLUSION Men included in the Intensive Blood Pressure Reduction in Acute Cerebral Haemorrhage trials had a greater odds of dying after intracerebral haemorrhage than women, which could not be readily explained by differing casemix or patterns of blood pressure management. CLINICAL TRIAL REGISTRATION The Intensive Blood Pressure Reduction in Acute Cerebral Haemorrhage trials studies are registered with ClinicalTrials.gov (NCT00226096 and NCT00716079).

Abstract
NaoXueShu oral liquid invigorates Qi and promotes blood circulation, which is mainly used for treating the acute stage of the meridian of hemorrhagic apoplexy and acute blood stasis syndrome during early convalescence. Its main clinical manifestations include hemiplegia, mouth askew, hemianesthesia, and inarticulateness. It is used mainly in patients with lobar hemorrhage, basal ganglia, and thalamus of the small amount of bleeding without disturbing consciousness of hypertensive cerebral. The purpose of this study was to evaluate the efficacy and adverse effects of NaoXueShu oral liquid on the treatment of cerebral hemorrhage. In this study, literature on randomized controlled trials was collected from seven databases to evaluate the clinical efficiency of the treatment of cerebral hemorrhage alone or combined with Western medicine. The methodologic quality of the included studies was assessed using a standard Cochrane system review and analyzed using RevMan 5.3.0 software. The study included 14 eligible randomized controlled trials. The results showed that the use of NaoXueShu oral liquid alone or combined with other drugs or auxiliary methods can play a significant role in the treatment of cerebral hemorrhage, especially hypertensive intracerebral hemorrhage.
