Objective:To investigate the effect of circular RNA bromodomain PHD finger transcription factor (circBPTF) targeting microRNA (miR)-224-3p on the damage of human retinal vascular endothelial cells (HRECs) induced by high glucose.Methods:HRECs were divided into control group and high glucose group, which were cultured with medium containing 5.5 mmol/L glucose and 30 mmol/L glucose for 48 hours, respectively.HRECs were transfected with siRNA negative control (si-NC), siRNA of circBPTF (si-circBPTF), miRNA mimic control (miR-NC), and miR-224-3p by Lipofectamine 2000, followed by cultured in 30 mmol/L glucose medium for 48 hours and were recorded as si-NC group, si-circBPTF group, miR-NC group and miR-224-3p group, respectively.HRECs were transfected with si-circBPTF and anti-miR-NC or si-circBPTF and anti-miR-224-3p by double transfection method, and then treated with 30 mmol/L glucose medium for 48 hours and were recorded as anti-miR-NC group and anti-miR-224-3p group, respectively.The expression of circBPTF and miR-224-3p was detected by real-time fluorescence quantitative PCR.Cell apoptosis was detected by flow cytometry.Reactive oxygen species (ROS) level was determined by 2′, 7′-dichlorodihydrofluorescein diacetate probe.Superoxide dismutase (SOD) activity and malondialdehyde (MDA) content were detected by colorimetric method.Expression of cleaved-caspase-3/caspase-3 and cleaved-caspase-9/caspase-9 proteins was detected by Western blot.The interaction between circBPTF and miR-224-3p was identified by the dual luciferase reporter method.Results:Compared with the control group, the apoptosis rate, cleaved-caspase-3/caspase-3 protein expression, cleaved-caspase-9/caspase-9 protein expression, ROS level, MDA content, and circBPTF relative expression were significantly increased and SOD activity and miR-224-3p expression were decreased in the high glucose group (all P<0.05).Compared with the si-NC group, circBPTF relative expression, ROS level, MDA content, cleaved-caspase-3/caspase-3 protein expression, cleaved-caspase-9/caspase-9 protein expression, and cell apoptosis rate were significantly reduced and SOD activity was significantly increased in the si-circBPTF group (all P<0.05).Compared with the miR-NC group, miR-224-3p relative expression and SOD activity were significantly enhanced and ROS level, MDA content, cleaved-caspase-3/caspase-3 protein expression, cleaved-caspase-9/caspase-9 protein expression and cell apoptosis rate were significantly reduced in the miR-224-3p group (all P<0.05).The relative luciferase activity of HRECs after co-transfection of wild type circBPTF and miR-224-3p mimic was 0.43±0.04, which was significantly decreased compared with 0.99±0.06 after co-transfection of wild type circBPTF and miR-NC ( t=23.297, P<0.05).Compared with anti-miR-NC group, the relative expression of miR-224-3p and SOD activity were significantly decreased and ROS level, MDA content, cell apoptosis rate, cleaved-caspase-3/caspase-3 protein expression, and cleaved-caspase-9/caspase-9 protein expression were significantly increased in the anti-miR-224-3p group (all P<0.05). Conclusions:Interfering with circBPTF can inhibit high glucose induced HRECs apoptosis and oxidative stress damage by targeting miR-224-3p.

Purpose: The risk stratification of pediatric anaplastic large cell lymphoma (ALCL) has not been standardized. In this study, new risk factors were included to establish a new risk stratification system for ALCL, and its feasibility in clinical practice was explored. Materials and Methods: On the basis of the non-Hodgkin’s lymphoma Berlin–Frankfurt–Munster 95 (NHL-BFM-95) protocol, patients with minimal disseminated disease (MDD), high-risk tumor site (multiple bone, skin, liver, and lung involvement), and small cell/lymphohistiocytic (SC/LH) pathological subtype were enrolled in risk stratification. Patients were treated with a modified NHL-BFM-95 protocol combined with an anaplastic lymphoma kinase inhibitor or vinblastine (VBL). Results: A total of 136 patients were enrolled in this study. The median age was 8.8 years. The 3-year event-free survival (EFS) and overall survival of the entire cohort were 77.7% (95% confidence interval [CI], 69.0% to 83.9%) and 92.3% (95% CI, 86.1% to 95.8%), respectively. The 3-year EFS rates of low-risk group (R1), intermediate-risk group (R2), and high-risk group (R3) patients were 100%, 89.5% (95% CI, 76.5% to 95.5%), and 67.9% (95% CI, 55.4% to 77.6%), respectively. The prognosis of patients with MDD (+), stage IV cancer, SC/LH lymphoma, and high-risk sites was poor, and the 3-year EFS rates were 45.3% (95% CI, 68.6% to 19.0%), 65.7% (95% CI, 47.6% to 78.9%), 55.7% (95% CI, 26.2% to 77.5%), and 70.7% (95% CI, 48.6% to 84.6%), respectively. At the end of follow-up, one of the five patients who received maintenance therapy with VBL relapsed, and seven patients receiving anaplastic lymphoma kinase inhibitor maintenance therapy did not experience relapse. Conclusion This study has confirmed the poor prognostic of MDD (+), high-risk site and SC/LH, but patients with SC/LH lymphoma and MDD (+) at diagnosis still need to receive better treatment (ClinicalTrials.gov number, NCT03971305).

BACKGROUND: Amygdala plays an important role in the neurobiological basis of panic disorder (PD), and the amygdala contains different subregions, which may play different roles in PD. The aim of the present study was to examine whether there are common or distinct patterns of functional connectivity of the amygdala subregions in PD using resting-state functional magnetic resonance imaging and to explore the relationship between the abnormal spontaneous functional connectivity patterns of the regions of interest (ROIs) and the clinical symptoms of PD patients. METHODS: Fifty-three drug-naïve, non-comorbid PD patients and 70 healthy controls (HCs) were recruited. Seed-based resting-state functional connectivity (rsFC) analyses were conducted using the bilateral amygdalae and its subregions as the ROI seed. Two samples t test was performed for the seed-based Fisher's z -transformed correlation maps. The relationship between the abnormal spontaneous functional connectivity patterns of the ROIs and the clinical symptoms of PD patients was investigated by Pearson correlation analysis. RESULTS: PD patients showed increased rsFC of the bilateral amygdalae and almost all the amygdala subregions with the precuneus/posterior cingulate gyrus compared with the HC group (left amygdala [lAMY]: t  = 4.84, P  <0.001; right amygdala [rAMY]: t  = 4.55, P  <0.001; left centromedial amygdala [lCMA]: t  = 3.87, P  <0.001; right centromedial amygdala [rCMA]: t  = 3.82, P  = 0.002; left laterobasal amygdala [lBLA]: t  = 4.33, P  <0.001; right laterobasal amygdala [rBLA]: t  = 4.97, P  <0.001; left superficial amygdala [lSFA]: t  = 3.26, P  = 0.006). The rsFC of the lBLA with the left angular gyrus/inferior parietal lobule remarkably increased in the PD group ( t  = 3.70, P  = 0.003). And most of the altered rsFCs were located in the default mode network (DMN). A significant positive correlation was observed between the severity of anxiety and the rsFC between the lSFA and the left precuneus in PD patients ( r  = 0.285, P  = 0.039). CONCLUSIONS Our research suggested that the increased rsFC of amygdala subregions with DMN plays an important role in the pathogenesis of PD. Future studies may further explore whether the rsFC of amygdala subregions, especially with the regions in DMN, can be used as a biological marker of PD.

Traditional Chinese Medicine (TCM) has its own unique features in the treatment of post-stroke depression (PSD). The kidney is the congenital foundation and is closely related to the brain. Kidney deficiency runs through the entire course of stroke. Liver regulates the normal operation of qi in the human body, which is closely related to depression syndrome. Kidney deficiency and liver depression affect each other. The treatment of PSD with the Bushen Shugan (tonifying the kidney and soothing the liver) method has achieved good efficacy in clinic. The method of tonifying kidney and soothing liver can not only reflect the holistic view of TCM and the association of viscera, but also coordinate the relationship between body and spirit. In the future, the development direction of PSD in TCM research should be to further strengthen the concept of co-regulation of body and spirit and integration of brain and viscera.

Objective:To study the role of a novel brain-derived peptide hypoxic-ischemic brain damage associated peptide (HIBDAP) in regulating pyroptosis of oxygen-glucose deprived (OGD) microglia.Methods:The sequence of HIBDAP was coupled with the sequence of cell-penetrating peptide transactivator of transcription (TAT) to form TAT-HIBDAP. Fluorescein isothiocyanate (FITC) labeled TAT-HIBDAP was added to microglia cells and observed under fluorescence microscope. Microglia cells were treated with different concentrations of TAT-HIBDAP (1, 5, 10, 20 μmol/L) and then OGD process. Cell pyroptosis was analyzed using lactate dehydrogenase (LDH) assay. The concentration of TAT-HIBDAP with the most prominent inhibiting effects was determined and selected for subsequent experiments. The pyroptosis morphology of the control group, the OGD group and the HIBDAP group (5 μmol/L TAT-HIBDAP+OGD) was observed using transmission electron microscope. The mRNA and protein expression of NOD-like receptor family pyrin domain containing 3 (NLRP3) inflammasomes were examined using real-time quantitative PCR and Western Blot analysis.Results:Fluorescence microscope showed FITC-labeled TAT-HIBDAP could successfully enter microglia cells. Compared with the OGD group, low concentrations of TAT-HIBDAP (1, 5, 10 μmol/L) could significantly reduce microglia pyroptosis and the concentration of 5 μmol/L showed the most prominent effects. Compared with the control group, OGD group showed typical pyroptosis morphology and HIBDAP group showed significantly improved morphology. The mRNA and protein expression of NLRP3 inflammasomes in the OGD group were significantly higher than the control group and also the HIBDAP group.Conclusions:The novel brain-derived peptide HIBDAP may reduce the expression of NLRP3 inflammasomes and inhibit the pyroptosis of OGD microglia.

Ménière's disease （MD） is an inner ear disease characterized by vertigo， tinnitus， hearing loss， and ear stuffiness. Modern therapies such as drugs， surgery， and vestibular function rehabilitation have limited effects in relieving the symptoms and reducing the recurrence. Traditional Chinese medicine （TCM） can alleviate the symptoms of MD with simple operation and mild adverse reactions while emphasizing psychological adjustment. The TCM treatment of MD is individualized depending on different stages and pathogenic factors. The internal treatment mainly targets phlegm， dampness， water， wind， fire， deficiency， and blood stasis. External interventions include acupuncture and moxibustion. This paper reviewed the published articles about the treatment of MD with TCM. In recent five years， the published studies were mainly clinical trials and experience discussion （or case reports）， and few reports of fundamental research were published. In these studies， the Western medicine diagnosis of MD mostly refers to the Diagnostic Basis and Efficacy Evaluation of Ménière's Disease （Guiyang， 2006） and the Guidelines for Diagnosis and Treatment of Ménière's Disease （2017）， while the TCM diagnosis mostly refers to the Criteria of Diagnosis and Therapeutic Effect of Diseases and Syndromes in Traditional Chinese Medicine issued by the National Administration of TCM in 1994. The efficacy was mostly evaluated based on clinical efficacy， scales， syndrome scores， pure tone audiometry， etc.， while caboratory indexes were rarely used. The available clinical studies about the treatment of MD with TCM generally have low quality of evidence and single intervention means. In the future， the research on the treatment of MD with TCM can be improved by standardizing the research program， improving the quality of evidence， exploring more intervention methods， and strengthening basic research.

Meige syndrome is one of the rare Diseases of neurology. It is a part of the group of segmental cranial dystonia, which affects more than two cranial muscle groups. Especially, blepharospasm is associated with another cranial dystonia. Currently, the etiology and pathogenesis of this disorder are not well-understood. Based on the theory of collaterals and the relationship between collateral disease and five zang organs,we try to classify the disease into the category of collateral disease, and hold that the mechasnism of disease is not only linked to brain, but also the five zang organs. The disorder of qi and blood leads to the "deficiency of qi and blood", "phlegm-damp" and "stagnant blood" in collateral. These pathological changes cause the deficiency of both qi and blood in brain marrow and tendon.We think that "unblocking and regulating the collterals"is the general program. Adjusting the five zang organs to heel the brain is the key point of the treatment. What's more, we create Tongmai Heluo Decoction to regulate qi and blood of the collateral. This decoction is composed of Huangqi Jianzhong Decoction with some herbal medicine for tonifying qi and activating blood. By adjusting the middle energizer, the qi and the qi movement of five zang organs are well regulated. We use this decoction effectively on refractory Meige syndrome.
