RESUMO
There is no report on the effects of sustained low-efficiency dialysis (SLED) plus hemoperfusion (HP) (SLED + HP) in patients with acute severe organophosphate (OP) poisoning (ASOPP). This study was designed to compare the therapeutic effectiveness between SLED + HP and continuous hemofiltration (CHF) plus HP (CHF + HP) in patients with ASOPP. In order to assess the two treatment methods, 56 patients with ASOPP were divided into CHF + HP group and SLED + HP group. The biochemical indicators, in-hospital duration, hemodynamic parameters, Acute Physiology, and Chronic Health Evaluation (APACHE II) score, and survival and mortality rates were compared. In both groups after treatment, the levels of serum creatine kinase isozyme MB, creatine kinase, creatinine, glutamic-oxalacetic transaminease, and glutamate-pyruvate transaminase, and the APACHE II scores on the first, second, and seventh day decreased (P < 0.05), whereas the levels of serum acetylcholinesterase increased. The two groups showed no statistical differences in in-hospital duration, biochemical indicators, APACHE II score, hemodynamic parameters, survival rate, or the mortality rate (P > 0.05). In conclusion, SLED has similar hemodynamic stability to CHF and the two treatment methods have similar effects on ASOPP patients. More importantly, SLED plus HP is relatively economical and convenient for patients with ASOPP in clinical practice.

BACKGROUND AIMS: We explored the potential therapeutic value of transplanting bone marrow (BM)-derived mesenchymal stromal cells (MSC) into utrophin/dystrophin-deficient double knock-out (dko) mice, a murine model of Duchenne muscular dystrophy. METHODS: MSC from male rats were isolated and transplanted into female dko mice via the caudal vein. Behavior and locomotor function were later evaluated, along with the expression of dystrophin and utrophin in the sarcolemma of myofiber tissues. The presence of grafted cells was confirmed via polymerase chain reaction for the sex-determining region of the Y-chromosome. RESULTS: Locomotor activity improved significantly (P < 0.05) from 5 to 15 weeks after cell transplantation, as measured by traction, rotating rod and running wheel tests. We also found that the expression of dystrophin and utrophin increased significantly (P < 0.05) and progressively in the sarcolemma from 5 to 15 weeks after transplantation. The median lifespan of mice in the normal group (74.1 weeks) was significantly (P < 0.001) higher than those in the control (22.0 weeks) and transplantation (35.0 weeks) groups, and the median lifespan of mice in the transplantation group was significantly (P < 0.001) higher than that in the control group. CONCLUSIONS: Results of this study demonstrate that BM MSC have potential value in xenogeneic transplantation therapy for muscular dystrophy.

BACKGROUND: IgA nephropathy (IgAN) is the most frequent type of primary glomerulonephritis globally and the leading cause of end-stage renal disease in young adults. Its pathogenesis is not fully known, but is largely attributed to genetic factors. This study was aimed to explore the prognostic values of key genes in IgAN. METHODS: The gene expression profile GSE93798 of 20 IgAN samples and 22 normal samples using glomeruli from kidney biopsy was adopted. Totally 447 upregulated and 719 downregulated differentially expressed genes were found in IgAN patients on the R software. The Gene Ontology enrichment and the Kyoto Encyclopedia of Gene and Genomes pathway were investigated on DAVID, and the protein-protein interaction network and the top 13 hub genes of the differentially expressed genes were built via the plug-in molecular complex detection and cytoHubba of Cytoscape. RESULTS: From the protein-protein interaction network, of the top 13 hub genes, FOS, EGFR, SIRT1, ALB, TFRC, JUN, IGF1, HIF1A, and SOCS3 were upregulated, while CTTN, ACTR2, CREB1, and CTNNB1 were downregulated. The upregulated genes took part in the HIF-1 signaling pathway, Choline metabolism in cancer, Pathways in cancer, Amphetamine addiction, Estrogen, TNF, and FoxO signaling pathways, and Osteoclast differentiation, while the downregulated genes were involved in Pathogenic Escherichia coli infection, Bacterial invasion of epithelial cells, prostate cancer, and melanogenesis. CONCLUSION: This study based on the Gene Expression Omnibus database updates the knowledge about the mechanism of IgAN and may offer new treatment targets.

BACKGROUND: Detection of M-type phospholipase A2 receptor (PLA2R) can be used in serologic diagnosis of idiopathic membranous nephropathy (IMN), but there are limited data about the sensitivity and specificity of its diagnostic values. METHODS AND RESULTS: Meta-analysis of diagnostic test studies assessing the values of PLA2R in diagnosis of IMN. MEDLINE, EMBASE, and CENTRAL databases and congress abstracts were searched for studies reporting the value of PLA2R to predict IMN. The quality of the studies was evaluated using the guidelines of the updated Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) tool. The results are summarized as sensitivity, specificity, and diagnostic odds ratio (OR). Data from 10 studies involving 1,550 participants were analyzed. Across all settings, the diagnostic OR for serum anti-PLA2R level to predict IMN at different stages was 247.41, with sensitivity of 0.69 and specificity of 0.99. The estimated sensitivity and specificity of serum anti-PLA2R level for diagnosis of IMN in the active stage were 74.0 and 95.0%, respectively, with diagnostic OR of 54.22. The estimated sensitivity and specificity of biopsy anti-PLA2R for diagnosis of IMN at different stages was 73.0 and 83.0%, respectively, with diagnostic OR of 13.75. CONCLUSIONS: This meta-analysis shows that serum anti-PLA2R level is of diagnostic value for IMN in the active stage. Future large-cohort prospective studies are required to reveal the diagnostic value of circulating anti-PLA2R antibodies versus PLA2R antigens in kidney biopsy for IMN at different stages.
