Objective To explore the independent risk factors for the 1 year stroke event in Chinese patients with atrial fibrillation (AF) and hypertension (HT).Methods Data of AF and HT patients in the Chinese Emergency Atrial Fibrillation Registry Study were retrospectively analyzed.The eligible patients were divided into the stroke group and the non-stroke group according to the result of 1 year follow-up.The predictors for the 1 year stroke event were identified by uni-and multi-variate Cox regression analysis with the baseline and therapeutic variables.Results A total of 1 118 AF and HT patients were enrolled in the study with the incidence of 1 year stroke event of 8.7%.All patients were divided into the stroke group (n =97) and the non-stroke group (n =1 021).Compared with the non-stroke group,more female patients were in the stroke group (68.0% vs 54.5%,P < 0.05) and the patients in the stroke group were older [(76.0 ± 9.4) years vs (71.9 ± 10.6) years,P < 0.01] with higher proportion of previous history of stroke (38.1% vs 23.8%,P <0.01).More patients were observed on the antihypertensive treatment in the non-stroke group (91.6% vs 85.6%,P < 0.05),while more patients on statins in the stroke group(45.4%vs 34.5%,P < 0.05).Multi-variate Cox regression analysis showed that age (HR =1.036,95% CI 1.010-1.062),female (HR =1.908,95% CI 1.170-3.110),previous stroke history (HR =1.680,95% CI 1.084-2.603),and no antihypertensive treatment (HR =1.955,95% CI 1.008-3.791) were independent risk factors for the 1 year stroke event in patients with AF and HT.Conclusion Age,female,previous stroke history and no antihypertensive treatment are the independent risk factors for the 1 year stroke event in patients with AF and HT.

PURPOSE: Studies have shown that diabetes mellitus (DM) is a risk factor for cardiovascular disease, including atrial fibrillation (AF); however, the clinical characteristics and prognostic impact of DM in patients with nonvalvular AF have not been well understood in China. MATERIALS AND METHODS: Included were 1644 consecutive patients with nonvalvular AF. Endpoints included all-cause mortality, cardiovascular mortality, stroke, major bleeding, and combined endpoint events (CEE) during a 1-year follow-up. RESULTS: The prevalence of DM was 16.8% in nonvalvular AF patients. Compared with non-diabetic AF patients, diabetic AF patients were older and tended to coexist with other cardiovascular diseases. Most patients with DM (93.5%) were eligible for anticoagulation, as determined by CHADS2 scores. However, only 11.2% of patients received anticoagulation. During a 1-year follow-up, the all-cause mortality and CEE rate in the DM group were significantly higher than those of the non-DM group, while the incidence of stroke was comparable. After multivariate adjustments, DM was still an independent risk factor for 1-year all-cause mortality [hazard ratio (HR)=1.558; 95% confidence interval (CI) 1.126-2.156; p=0.007], cardiovascular mortality (HR=1.615; 95% CI 1.052-2.479; p=0.028), and CEE (HR=1.523; 95% CI 1.098-2.112; p=0.012), yet not for stroke (HR=1.119; 95% CI 0.724-1.728; p=0.614). CONCLUSION: DM is a common morbidity coexisting with nonvalvular AF and is associated with an increased risk of 1-year all-cause mortality, cardiovascular mortality, and CEE. However, no increased risk of stroke was found during a 1-year follow-up in patients with AF and DM.

Objective:To investigate the baseline characteristics and 1-year follow-up prognosis of elderly (age ≥75 years) emergency department (ED) patients with atrial fibrillation (AF).Methods:From 2009 to 2011, patients with AF aged ≥75 years were continuously enrolled in the ED in 20 hospitals. The baseline characteristics and treatment status of the patients were collected and followed up for 1 year. The primary endpoint was all-cause death; Secondary endpoints were cardiovascular death, stroke, major bleeding and major adverse events. Uni- and multivariate Cox regression models were used to analyze the independent risk factors for the above events.Results:A total of 766 elderly ED patients with AF were enrolled, the average age was 80.76±4.66 years old, and 56.9% were female. The 1-year all-cause mortality was 24.3%, cardiovascular mortality was 12.8%, stroke rate was 10.6%, major adverse event rate was 33.6%, and the readmission rate was 32%. Multivariate Cox regression analysis showed that age ( HR1.073, 95% CI 1.042-1.105), heart rate ( HR1.008, 95% CI 1.002-1.013), history of dementia/cognitive impairment ( HR1.849, 95% CI 1.016) ~3.365), and history of chronic obstructive pulmonary disease ( HR1.824, 95% CI 1.303-2.551) were independent risk factors for death in elderly patients with AF in 1-year follow-up; female (HR1.664, 95% CI 1.036-2.675), and history of hypertension ( HR2.035, 95% CI 1.080-3.836), history of dementia/cognitive impairment ( HR2.773, 95% CI 1.220-6.302) were independent risk factors for 1-year stroke in elderly patients with AF. Conclusions:The prognosis of elderly ED patients with AF is poor. Age, heart rate, history of dementia/cognitive impairment, and history of chronic obstructive pulmonary disease are independent risk factors for 1-year all-cause death and major adverse events in elderly ED patients with AF. Female, history of hypertension, and history of dementia/ cognitive impairment are independent risk factors for stroke in elderly ED patients with AF.

ObjectiveTo observe the clinical effectiveness and safety of Xuandi Ziyin Mixture (玄地滋阴合剂) for central precocious puberty (CPP) in girls with syndrome of yin deficiency and fire exuberance, and to analyse the effect of body mass index (BMI) on the effectiveness. MethodsA total of 236 girls with CPP of yin deficiency and fire exuberance syndrome were included, and all of them were given Xuandi Ziyin Mixture, 30 ml each time, twice a day, for a total treatment period of 6 months. Before and after treatment, children's weight, height and bone age were measured, BMI and BMI Z-score (BMI Z) and the difference between bone age and actual age were calculated; ultrasound was used to detect uterine and ovarian sizes, and to calculate uterine volume (Vuterus), bilateral ovarian volume (Vleft ovary, Vright ovary), and bilateral maximal follicle diameters (rleft follicle and rright follicle); and serum sex hormones were measured, including follicle-stimulating hormone (FSH), luteinising hormone (LH), prolactin (PRL), estradiol (E2), and testosterone (T), and were scored for traditional Chinese medicine (TCM) syndrome. Multiple linear regression was used to analyse the influence factors of the difference between bone age and actual age, and changes in uterine volume. The children were divided into the normal weight group and the overweight/obesity group according to baseline BMI, and the bone age, the difference between bone age and actual age, Vuterus and BMI Z scores before and after treatment were compared between the two groups. ResultsFinally, 199 children entered the statistical analysis. Compared with pre-treatment, the bone age, BMI and BMI Z scores of the children increased after treatment, and the difference between bone age and actual age, TCM syndrome scores, Vuterus, Vleft ovary, Vright ovary, rleft follicle and rright follicle decreased; and the levels of serum FSH, LH, E2, and T significantly decreased (P<0.05 or P<0.01). The difference between bone age and actual age was negatively correlated with LH and Vuterus (P<0.05), and changes in uterine volume were positively correlated with LH (P<0.01). Comparing between the groups before and after treatment, the bone age, difference between bone age and actual age, and BMI Z scores of children in the normal weight group (100 cases) were significantly smaller than those in the overweight/obesity group (99 cases) (P<0.01). Compared with pre-treatment, the bone age of the children in both groups increased, but the difference between bone age and actual age and Vuterus were significantly smaller (P<0.01). Further comparison of Δ bone age and actual age difference and ΔVuterus (Δ = post-treatment value

Nerve regeneration in adult mammalian spinal cord is poor because of the lack of intrinsic regeneration of neurons and extrinsic factors - the glial scar is triggered by injury and inhibits or promotes regeneration. Recent technological advances in spatial transcriptomics (ST) provide a unique opportunity to decipher most genes systematically throughout scar formation, which remains poorly understood. Here, we first constructed the tissue-wide gene expression patterns of mouse spinal cords over the course of scar formation using ST after spinal cord injury from 32 samples. Locally, we profiled gene expression gradients from the leading edge to the core of the scar areas to further understand the scar microenvironment, such as neurotransmitter disorders, activation of the pro-inflammatory response, neurotoxic saturated lipids, angiogenesis, obstructed axon extension, and extracellular structure re-organization. In addition, we described 21 cell transcriptional states during scar formation and delineated the origins, functional diversity, and possible trajectories of subpopulations of fibroblasts, glia, and immune cells. Specifically, we found some regulators in special cell types, such as Thbs1 and Col1a2 in macrophages, CD36 and Postn in fibroblasts, Plxnb2 and Nxpe3 in microglia, Clu in astrocytes, and CD74 in oligodendrocytes. Furthermore, salvianolic acid B, a blood-brain barrier permeation and CD36 inhibitor, was administered after surgery and found to remedy fibrosis. Subsequently, we described the extent of the scar boundary and profiled the bidirectional ligand-receptor interactions at the neighboring cluster boundary, contributing to maintain scar architecture during gliosis and fibrosis, and found that GPR37L1_PSAP, and GPR37_PSAP were the most significant gene-pairs among microglia, fibroblasts, and astrocytes. Last, we quantified the fraction of scar-resident cells and proposed four possible phases of scar formation: macrophage infiltration, proliferation and differentiation of scar-resident cells, scar emergence, and scar stationary. Together, these profiles delineated the spatial heterogeneity of the scar, confirmed the previous concepts about scar architecture, provided some new clues for scar formation, and served as a valuable resource for the treatment of central nervous system injury.
