Objective To evaluate whether Vitamin B supplementation could prevent ischemic stroke recurrence.Methods Randomized controlled trials (RCTs) observing Vitamin B supplementation in patients with stroke was performed in databases including ScienceDirect, PubMed/Medline, China National Knowledge Infrastructure, Chinese Biomedical Data-Base, Wanfang Database, and VIP Chinese Science and Technology Journal Database to find related studies in English or Chinese published before August 2016. The patients in control group received a placebo or basic therapy without Vitamin B, and those in experimental group was treated with Vitamin B alone or Vitamin B on the basis of conventional treatment. The data were collected by two researchers independently and the quality of studies was assessed by the modified Jadad Scale. The Meta-analysis was performed using Stata 12.0, funnel plot was drawn, and Egger and Begg regressions were used to evaluate the publication bias, and sensitivity was also analyzed. Results Seven RCTs studies were enrolled to analyze with a total number of 9846 stroke patients, 4755 patients in control group, and 5091 in experimental group, respectively. ① Vitamin B supplementation for prevention of recurrent stroke: heterogeneity test results showed a heterogeneity in literatures enrolled (I2 = 62.9%,P = 0.009), and a random effect model was used for Meta-analysis. It was shown that the incidence of recurrent stroke in the experimental group was significantly lower than that in the control group [pooled relative risk(RR) = 0.64, 95% confidence interval (95%CI) = 0.47-0.87], which indicated that the supplementation of Vitamin B could prevent the recurrence of stroke. Cumulative Meta-analysis showed that Vitamin B supplementation exhibited positive effects in the prevention stroke recurrence from 2012. The 95%CI tended to be stable while demonstrating good change trend as sample growing. The publication bias evaluation results showed that the funnel plot was not symmetrical by visual inspection, further quantitative analysis showed thatP value from Egger regression was 0.008, while that from Begg regression was 0.035, bothP < 0.05, suggesting there were some publication bias. The sensitivity analysis showed that the overall results were stable and reliable. ② The effect of Vitamin B supplementation on plasma homocysteine (Hcy) levels in stroke patients: heterogeneity test results showed a heterogeneity in literatures enrolled (I2 = 96.2%,P = 0.000), and a random effect model was used for Meta-analysis. It was shown that compared with control group, the plasma Hcy levels of patients after Vitamin B supplementation in experimental group were significantly decreased [pooled weighted mean difference (WMD) = -6.92, 95%CI = -9.11 to -4.73), indicating that Vitamin B could significantly reduce plasma Hcy levels in stroke patients. Cumulative meta analysis showed that, as time went on, the relevant research samples were increased, 95%CI tended to be stable and the variation tendency was better. The publication bias evaluation results showed that the funnel plot was symmetry by visual inspection, and further quantitative analysis showed that theP value from Egger regression was 0.345, and that from Begg regression was 0.764, bothP > 0.05, which indicating that there was no evidence of publication bias in the study included.Conclusions Vitamin B supplementation was associated with a lower risk of recurrent stroke in stroke patients and could significantly improve the quality of secondary prevention of stroke. Furthermore, supplementation of Vitamin B could reduce plasma Hcy levels in stroke patients which might contribute to its effect in preventing stroke recurrence.

Objective To explore the relationship between PANoptosis and hepatic ischemia-reperfusion injury (HIRI), and to screen the key genes of PANoptosis in HIRI. Methods PANoptosis-related differentially expressed genes (PDG) were obtained through the Gene Expression Omnibus database and GeneCards database. Gene ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and Gene Set Enrichment Analysis (GSEA) were used to explore the biological pathways related to PDG. A protein-protein interaction network was constructed. Key genes were selected, and their diagnostic value was assessed and validated in the HIRI mice. Immune cell infiltration analysis was performed based on the cell-type identification by estimating relative subsets of RNA transcripts. Results A total of 16 PDG were identified. GO analysis showed that PDG were closely related to cellular metabolism. KEGG analysis indicated that PDG were mainly enriched in cellular death pathways such as apoptosis and immune-related signaling pathways such as the tumor necrosis factor signaling pathway. GSEA results showed that key genes were mainly enriched in immune-related signaling pathways such as the mitogen-activated protein kinase (MAPK) signaling pathway. Two key genes, DFFB and TNFSF10, were identified with high accuracy in diagnosing HIRI, with areas under the curve of 0.964 and 1.000, respectively. Immune infiltration analysis showed that the control group had more infiltration of resting natural killer cells, M2 macrophages, etc., while the HIRI group had more infiltration of M0 macrophages, neutrophils, and naive B cells. Real-time quantitative polymerase chain reaction results showed that compared with the Sham group, the relative expression of DFFB messenger RNA in liver tissue of HIRI group mice increased, and the relative expression of TNFSF10 messenger RNA decreased. Cibersort analysis showed that the infiltration abundance of naive B cells was positively correlated with DFFB expression (r=0.70, P=0.035), and the infiltration abundance of M2 macrophages was positively correlated with TNFSF10 expression (r=0.68, P=0.045). Conclusions PANoptosis-related genes DFFB and TNFSF10 may be potential biomarkers and therapeutic targets for HIRI.

ObjectiveTo investigate the effect of Mahonia bealei leaf extract on depression of rats and the underlying mechanism. MethodThe chemical constituents of the extract were analyzed by HPLC-MS/MS. Forced swimming test and tail suspension test were carried out to estimate the antidepressant effect. The mice were randomly assigned into the following groups: blank group, positive control group (fluoxetine, 10 mg·kg-1), and Mahonia bealei leaf extract groups (10, 2.5 g·kg-1). The gavage lasted for 12 days and the immobility time of the mice in the tests was recorded 1 h after the last administration. Furthermore, to explore the underlying mechanism of the antidepressant effect, we established the rat depression model by intraperitoneal injection with reserpine (0.5 mg·kg-1). Rats were grouped as follows: blank group, model group, positive control group (fluoxetine, 1.8 mg·kg-1), and Mahonia bealei leaf extract groups (10, 2.5 g·kg-1). The gavage, once a day, lasted for 10 consecutive days. The depression of rats was detected by behavioral tests 1 h after the last administration. The levels of interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) in serum of rats were detected by enzyme-linked immunosorbent assay (ELISA). The protein expression of IL-6 and interleukin-1β (IL-1β) in brain tissue was detected by immunohistochemical staining. The protein levels of nuclear transcription factor-κB (NF-κB) and NOD-like receptor protein 3 (NLRP3) in hippocampus of rats were detected by Western blot. ResultSeven chemical constituents, mainly alkaloids, were identified from the extract. Compared with the blank group, Mahonia bealei leaf extract shortened the immobility time of mice in tail suspension and forced swimming tests. Compared with the blank group, the modeling of rat depression increased the blepharoptosis incidence and retention time in circles (P<0.05, P<0.01), elevated the levels of IL-6 and TNF-α in serum (P<0.05), and up-regulated the protein levels of IL-6, IL-1β, NF-κB, and NLRP3 in brain tissues (P<0.01). Compared with the model group, high dose of Mahonia bealei leaf extract shortened the retention time in circles (P<0.05), lowered the levels of IL-6 and TNF-α in serum (P<0.05, P<0.01), and down-regulated the protein levels of IL-6, IL-1β, NF-κB, and NLRP3 (P<0.01) in brain tissues. ConclusionMahonia bealei leaf extract had significant antidepressant effect and alleviated the inflammatory response in reserpine-induced rat model of depression, the mechanism of which may be related to the inhibition of NF-κB/NLRP3 signaling pathway.
