lncR-GAS5 upregulates the splicing factor SRSF10 to impair endothelial autophagy, leading to atherogenesis / 医学前沿

Long noncoding RNAs (lncRNAs) play a critical role in the regulation of atherosclerosis. Here, we investigated the role of the lncRNA growth arrest-specific 5 (lncR-GAS5) in atherogenesis. We found that the enforced expression of lncR-GAS5 contributed to the development of atherosclerosis, which presented as increased plaque size and reduced collagen content. Moreover, impaired autophagy was observed, as shown by a decreased LC3II/LC3I protein ratio and an elevated P62 level in lncR-GAS5-overexpressing human aortic endothelial cells. By contrast, lncR-GAS5 knockdown promoted autophagy. Moreover, serine/arginine-rich splicing factor 10 (SRSF10) knockdown increased the LC3II/LC3I ratio and decreased the P62 level, thus enhancing the formation of autophagic vacuoles, autolysosomes, and autophagosomes. Mechanistically, lncR-GAS5 regulated the downstream splicing factor SRSF10 to impair autophagy in the endothelium, which was reversed by the knockdown of SRSF10. Further results revealed that overexpression of the lncR-GAS5-targeted gene miR-193-5p promoted autophagy and autophagic vacuole accumulation by repressing its direct target gene, SRSF10. Notably, miR-193-5p overexpression decreased plaque size and increased collagen content. Altogether, these findings demonstrate that lncR-GAS5 partially contributes to atherogenesis and plaque instability by impairing endothelial autophagy. In conclusion, lncR-GAS5 overexpression arrested endothelial autophagy through the miR-193-5p/SRSF10 signaling pathway. Thus, miR-193-5p/SRSF10 may serve as a novel treatment target for atherosclerosis.

Advances in neuroimaging studies of cerebral small vessel disease combined with depression / 中华行为医学与脑科学杂志

Depression is a common psychiatric symptom in cerebral small vessel disease (CSVD), which has a certain relationship with impairment of cognitive function and can significantly increase the mortality and morbidity of CSVD patients. The occurrence of CVSD-associated depression is less related to psychological stress, but is associated with the impairment of the brain's emotional circuit. This article reviewed the correlation between the imaging features of CVSD and the occurrence and development of depression in recent years, and the neuroimaging mechanism of depression associated with CVSD. Many literatures have shown that deep white matter hyperintensities and asymptomatic lacunar infarction in the basal ganglia are independent risk factors for depression in CSVD, and the reduction of local brain volume is associated with depression. The neuroimaging mechanism of depression associated with CSVD suggests that the occurrence of depressive symptoms is related to the neural circuits in the lobar cortex-subcortical limbic area. These findings provide clues for exploring the neuropathological mechanisms and specific treatment methods of depression associated with CVSD.

Diagnosis, treatment and prevention of cerebral venous thrombosis / 中华神经科杂志

Cerebral venous thrombosis is a rare type of cerebrovascular diseases. Its etiology and risk factors are different from those of cerebral artery occlusive disease, which are mainly related to prethrombotic state caused by various reasons. The clinical symptoms are complex and diverse, lacking of characteristic manifestations. Neuroimaging examination is the main basis for the diagnosis. Magnetic resonance imaging/magnetic resonance venography is the best way to diagnose the disease and follow-up the patients′ condition. At present, the management of the disease is mainly aimed at etiology treatment and vascular recanalization treatment, of which anticoagulation is the most important means, and there is still a lack of recognized effective measures in prevention.

Correlation study of cerebral small vessel disease and retinal vascular network parameters / 中国神经精神疾病杂志

Objective To investigate the correlation of cerebral small vessel disease with retinal vascular network parameters using fully automatic retinal image analysis of fundus photographs. Methods A total of 121 patients undertak?ing fundus photography in a sitting position were included. They were divided into either a cerebral small vessel disease group (n=80) or an artery atherosclerotic cerebral infarction group (n=41) according to their cerebral MRI findings. The clinical data and retinal vascular network parameters were compared between the two groups. We used logistic regression to analyse risk factors of the small vessel disease. Results The percentage of males, the incidence of smoking and serum uric acid level in the small vessel disease group were lower than those in the artery atherosclerotic cerebral infarction group(P<0.05). The bifurcation coefficient and asymmetry index of venule in the small vessel disease group were lower than those in the artery atherosclerotic cerebral infarction group(P<0.05). Logistic regression analysis showed that after adjusting vascular risk factors, decreased asymmetry index of venule was associated with cerebral small vessel disease (OR=1.16,95% CI:1.05-1.38,P<0.05). Conclusions The decreased asymmetry index of venule is associated with small vessel disease which can be used as an early diagnotic indicator.

Objective To investigate the clinical and imaging characteristics in cryptogenic stroke with right-to-left shunt (RLS). Methods Fifty-two patients with cryptogenic ischaemic stroke were included in the study and divided into two groups according to transcranial Doppler (TCD) bubble test: RLS group (twenty-five patients) and non-RLS group (twenty-seven patients). The demographic data, traditional risk factors of stroke and characteristics of le?sion patterns were compared between two subgroups. Results There was no significant difference between the groups in age or sex ratio. The percentage of patients with no risk factors was significantly higher in RLS group than non-RLS group (44%vs. 14.8%, P=0.015). The lesion was more frequently observed in the vertebrobasilar artery territory in RLS group (56%vs. 14.8%, P0.05). Conclusions Vertebrobasilar Stroke without traditional cerebrovascular risk factors is more likely to be RLS-associated, which requires an advanced TCD bubble test to find the potential cause of stroke.
