Neutrophil extracellular traps correlate with severity and prognosis in patients with ischemic stroke: a systematic review and meta-analysis.

BACKGROUND AND OBJECTIVE: A correlation between neutrophil extracellular traps (NETs) and ischemic stroke (IS) has been hypothesized, but the results of relevant studies remain controversial. The purpose was to determine whether NETs have an impact on ischemic stroke. METHODS: The studies on the correlation between NETs and IS were retrieved from CNKI, Wanfang Data, VIP, CBM, PubMed, Web of Science, Embase, and Cochrane databases by computer from the start of the database to December 2022. The study adhered to PRISMA guidelines. The PICOS model was used to create inclusion criteria. Two researchers screened the literature and extracted the relevant data. The quality of the included studies was evaluated using the NOS and the 11 items recommended by the AHRQ, and meta-analysis was completed using Stata 15.1 software. RESULTS: The researchers included 752 patients in 7 studies (4 case-control studies and 3 cross-sectional studies). The meta-analysis found NETs are positively associated with the severity of IS at the time of onset [r(95% CI) = 0.31(0.24, 0.38), P < 0.001]. NETs are positively associated with a worse prognosis of IS [r(95% CI) = 0.34(0.13, 0.53), P = 0.003]. CONCLUSION: The presence of NETs is positively related to the severity and prognosis of IS. Higher levels of NETs indicate a more severe disease and a poorer prognosis. Because the number and quality of included studies are limited, the above results must be supported by further high-quality studies.

Attention bias modification for depression: A systematic review and meta-analysis.

Background: Depression is a mental health disorder characterized by affective, somatic, and cognitive symptoms. Attention bias modification (ABM) has been widely used to treat depression. However, the results seem inconsistent. We conducted a systematic review and meta-analysis to investigate the efficacy of ABM for depression and to explore the optimal protocol of ABM. Methods: Seven databases were systematically searched from their inceptions to 5 October 2022 to include randomized controlled trials (RCTs) of ABM for depression. Two independent reviewers selected the eligible articles, extracted data, and evaluated the risk of bias using version 2 of the Cochrane risk-of-bias tool (ROB 2.0) for randomized trials. The primary outcome was the evaluation of depressive symptoms using widely accepted and validated scales. The secondary outcomes included rumination and attentional control. Meta-analysis was conducted by using RevMan (version 5.4) and Stata (version 12.0). Subgroup analyses and meta-regressions were performed to identify the source of heterogeneity. The certainty of the evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE). Results: A total of 19 trials involving 20 datasets (1,262 participants) were included. The overall risk of bias in one study was rated as low risk of bias, three studies were considered as high, and the remaining studies were some concerns. Compared with attention control training (ACT), ABM had a greater effect in the improvement of depression (SMD = -0.48, 95% CI -0.80 to -0.17, I2 = 82%) and rumination (MD = -3.46, 95% CI -6.06 to -0.87, I2 = 0%). No significant differences were observed in the attentional control outcome between ABM and ACT (MD = 3.07, 95% CI -0.52 to 6.65, I 2 = 0%). Subgroup analysis demonstrated that adults exhibited a greater decrease in depression scores than adolescents. ABM using the dot-probe task, training target stimulus presented by face, and training directions by left-right were associated with better antidepressant effects. ABM training delivered in the laboratory tended to yield a better effect than those conducted at home. Sensitivity analysis indicated that the results were robust. The certainty of the evidence for all outcomes was low or very low, and publication bias may exist. Conclusion: Due to high heterogeneity and limited studies, not enough current evidence supported that ABM could be an effective intervention to relieve depressive symptoms. More rigorous RCTs are required to verify the benefits and to explore the optimal protocol of ABM training for depression.Systematic Review Registration: [PROSPERO], identifier [No. CRD42021279163].

The conscious processing of emotion in depression disorder: a meta-analysis of neuroimaging studies.

Background: Depression is generally accompanied by a disturbed conscious processing of emotion, which manifests as a negative bias to facial/voice emotion information and a decreased accuracy in emotion recognition tasks. Several studies have proved that abnormal brain activation was responsible for the deficit function of conscious emotion recognition in depression. However, the altered brain activation related to the conscious processing of emotion in depression was incongruent among studies. Therefore, we conducted an activation likelihood estimation (ALE) analysis to better understand the underlying neurophysiological mechanism of conscious processing of emotion in depression. Method: Electronic databases were searched using the search terms "depression," "emotion recognition," and "neuroimaging" from inceptions to April 10th, 2023. We retrieved trials which explored the neuro-responses of depressive patients to explicit emotion recognition tasks. Two investigators independently performed literature selection, data extraction, and risk of bias assessment. The spatial consistency of brain activation in conscious facial expressions recognition was calculated using ALE. The robustness of the results was examined by Jackknife sensitivity analysis. Results: We retrieved 11,365 articles in total, 28 of which were included. In the overall analysis, we found increased activity in the middle temporal gyrus, superior temporal gyrus, parahippocampal gyrus, and cuneus, and decreased activity in the superior temporal gyrus, inferior parietal lobule, insula, and superior frontal gyrus. In response to positive stimuli, depressive patients showed hyperactivity in the medial frontal gyrus, middle temporal gyrus, and insula (uncorrected p < 0.001). When receiving negative stimuli, a higher activation was found in the precentral gyrus, middle frontal gyrus, precuneus, and superior temporal gyrus (uncorrected p < 0.001). Conclusion: Among depressive patients, a broad spectrum of brain areas was involved in a deficit of conscious emotion processing. The activation of brain regions was different in response to positive or negative stimuli. Due to potential clinical heterogeneity, the findings should be treated with caution.

Ten Hotspot MicroRNAs and Their Potential Targets of Chondrocytes Were Revealed in Osteoarthritis Based on Bibliometric Analysis.

Background: Osteoarthritis (OA) is one of the most common joint disorders and debilitating diseases. Current evidence suggests that microRNAs (miRNAs) play a critical role in the pathogenesis of OA and have great potential as new biomarkers and therapeutic targets. We aimed to analyze the trends and research status on miRNAs in OA and further demonstrate the hotspot miRNAs in OA via CiteSpace and VOSviewer. Methods: Publications regarding miRNAs and OA were extracted from the Web of Science (WOS) database on October 30, 2021. We assessed the number of publications, institutions, countries, authors, journals, cited references, and keywords with the help of the software tools CiteSpace and VOSviewer. Results: A total of 1109 articles were included. Research related to miRNAs and OA began to appear in 2008, and the overall trend is increasing. Chinese institutions have a leading advantage in the number of publications but lack high-quality and high-cited research and are laggard in co-cited literature. Ten miRNAs including miR-140, miR-146, miR-34, miR-181, miR-27, miR-9, miR-29, miR-21, miR-26, and miR-155 and chondrocytes were revealed as the most obvious miRNAs and a potential target for OA based on bibliometric analysis. More focus will be placed on a comprehensive study on chondrocytes regulated by miRNAs, which may accelerate possible diagnostic biomarkers and diagnostic biomarkers of OA in the future.

Effectiveness of Kinesio taping on peripheral facial paralysis: A protocol for systematic review and meta-analysis.

BACKGROUND: Peripheral facial paralysis is a rapid unilateral facial paralysis or paralysis of unknown etiology. Nearly 30% of patients leave sequela that have a negative impact on the patient's quality of life, both physically and psychologically. As its safety, convenience and effectiveness, Kinesio taping has been gradually used in the rehabilitation of peripheral facial paralysis. However, whether Kinesio taping is effective for peripheral facial paralysis is still unknown. The purpose of this systematic review (SR) and meta-analysis will summarize the current evidence of Kinesio taping used as an intervention for peripheral facial paralysis. METHODS AND ANALYSIS: We will search the following electronic databases for randomized controlled trials (RCTs) and controlled clinical trials (CCTs) to evaluate the effectiveness of Kinesio taping in treating peripheral facial paralysis: China National Knowledge Infrastructure (CNKI), Wanfang Date, SinoMed, Technology Periodical Database (VIP), PubMed, Embase, Web of Science, and The Cochrane Library. Each database will be searched from inception to April 2020. Studies that present clear descriptions of Kinesio taping in treating peripheral facial paralysis administration are published in peer-reviewed journals in any languages and are published in full will be taken into consideration. The entire process will include study selection, data extraction, risk of bias assessment and meta-analyses. Assessment of risk of bias and data synthesis will be conducted using Review Manager 5.3 software. RESULTS: The current evidence on the Kinesio taping for managing peripheral facial paralysis will be illustrated using subjective reports and objective measures of performance. The primary outcome is the effective rate. Secondary outcomes include House-Brackmann scale, Portmann score, facial nerve conduction velocity, Facial Disability Index, Facial Disability Index include Facial Function score and social Function score. CONCLUSION: This protocol will present evidence on the efficacy of Kinesio taping in relieving peripheral facial paralysis. ETHICS AND DISSEMINATION: Since all the data used in this SR and meta-analysis have been published, ethical approval is not required for this review. The results of this SR will be published in a peer-reviewed journal or presented at conferences. INPLASY ID:: (INPLASY2020100008).

[Effect of electroacupuncture on neurological deficit and activity of TLR2/NF-κB signaling in ce-rebral ischemia /reperfusion injury rats].

OBJECTIVE: To observe the effect of electroacupuncture (EA) on neurological behavior and activity of Toll-like receptor 2 / nuclear factor kappa B (TLR2/NF-κB) signaling of the ischemic cerebral area in cerebral ischemia-reperfusion injury (CIRI) rats, so as to explore its mechanisms underlying improvement of CIRI. METHODS: A total of 120 male SD rats were randomly divided into blank control, sham operation, model, EA and EA＋NF-κB inhibitor (Pyrrolidine Dithiocarbamate Hydrochloride, PDTC, EA＋PDTC) groups which were further divided into 3, 7, 14 and 28 d subgroups (n＝6 in each subgroup). The CIRI model was established by occlusion of the middle cerebral artery for 90 min, followed by reperfusion. EA (1－20 Hz, 6 V) was applied to "Shuigou" (GV26), "Neiguan" (PC6), "Sanyinjiao" (SP6) and "Weizhong" (BL40) for 30 min, once a day for 28 days. For rats of the EA＋PDTC group, PDTC solution (120 mg/kg) was intraperitoneally injected on the 3rd day after successful modeling and before EA intervention. The neurological deficit severity (Zea Longa score) was assessed 3, 7, 14 and 28 days after modeling. The expression levels of TLR2, Interleukin-1 receptor-associated kinase (IRAK) and NF-κB mRNAs in the ischemic penumbra region of brain tissue were detected by real-time fluorescence quantitative PCR. RESULTS: Following modeling, the neurological deficit scores were significantly increased from the 3rd day on after CIRI (P<0.05), the expression levels of TLR2 mRNA on day 3, 7, 14 and 28, and IRAK mRNA on day 3 and 7, as well as NF-κB mRNA on day 3, 7 and 14 were significantly up-regulated in the model group relevant to the blank control group (P<0.05). After EA intervention, the neurological deficit scores were significantly decreased in the EA group on day 3, 7 and 28 and in the EA＋PDTC group on day 3, 7, 14 and 28 in comparison with those of the model group (P<0.05). In addition, the expression levels of TLR2 mRNA and NF-κB mRNA on day 3, 7 and 14 in the EA group, and on day 3, 7, 14 and 28 in the EA＋PDTC group, IRAK mRNA on day 3 in the EA and EA＋PDTC group were significantly down-regulated (P<0.05), but those of IRAK mRNA on day 14 and 28 in the EA group were significantly up-regulated in comparison with those of the model group (P<0.05). The effect of the EA＋PDTC was obviously superior to that of simple EA in down-regulating the expression of TLR2 (on day 28), and IRAK (on day 3, 14, 28), and NF-κB (on day 3, 7 and 14) (all P<0.05). CONCLUSION: EA stimulation can improve the symptoms of neurological deficits in CIRI rats, which may be related to its effect in suppressing the expression of TLR2, NF-κB and IRAK mRNAs of the ischemic cerebral tissue, i．e., down-regulating the activity of TLR2/NF-κB signaling.
