RESUMEN
BACKGROUND: Blood pressure (BP) variability is highly correlated with cardiovascular and kidney outcomes in patients with chronic kidney disease (CKD). However, appropriate BP targets in patients with CKD remain uncertain. METHODS: We searched PubMed, Embase, and the Cochrane Library for randomized controlled trials (RCTs) of CKD patients who underwent intensive BP management. Kappa score was used to assess inter-rater agreement. A good agreement between the authors was observed to inter-rater reliability of RCTs selection (kappa = 0.77; P = 0.005). RESULTS: Ten relevant studies involving 20 059 patients were included in the meta-analysis. Overall, intensive BP management may reduce the incidence of cardiovascular disease mortality (RR: 0.69, 95% CI: 0.53 to 0.90, P: 0.01), all-cause mortality (RR: 0.77, 95% CI: 0.67 to 0.88, P < 0.01) and composite cardiovascular events (RR: 0.84 95% CI: 0.75 to 0.95, P < 0.01) in patients with CKD. However, reducing BP has no significant effect on the incidence of doubling of serum creatinine level or 50% reduction in GFR (RR: 1.26, 95% CI: 0.66 to 2.40, P = 0.48), composite renal events (RR 1.07, 95% CI: 0.81 to 1.41, P = 0.64) or SAEs (RR: 0.97, 95% CI: 0.90 to 1.05, P = 0.48). CONCLUSION: In patients with CKD, enhanced BP management is associated with reduced all-cause mortality, cardiovascular mortality, and incidence of composite cardiovascular events.

BACKGROUND: The application of laparoscopic catheterization technology in peritoneal dialysis (PD) patients has recently increased. However, the advantages and disadvantages of laparoscopic versus conventional open PD catheter placement are still controversial. The aim of this meta-analysis is to assess the complications of catheterization in PD patients and to provide a reference for choosing a PD-catheter placement technique in the clinic. METHODS: We searched numerous databases, including Embase, PubMed, CNKI and the Cochrane Library, for published randomized controlled trials (RCTs). RESULTS: Eight relevant studies (n = 646) were included in the meta-analysis. The pooled results showed a lower incidence of catheter migration (OR: 0.42, 95% CI: 0.19 to 0.90, P: 0.03) and catheter removal (OR: 0.41, 95% CI: 0.21 to 0.79, P: 0.008) but a higher incidence of bleeding (OR: 3.25, 95% CI: 1.18 to 8.97, P: 0.02) with a laparoscopic approach than with a conventional approach. There was no significant difference in the incidence of omentum adhesion (OR: 0.32, 95% CI: 0.05 to 2.10, P: 0.24), hernia (OR: 0.38, 95% CI: 0.09 to 1.68, P: 0.20), leakage (OR: 0.69, 95% CI: 0.38 to 1.26, P: 0.23), intestinal obstruction (OR: 0.96, 95% CI: 0.48 to 1.91, P: 0.90) or perforation (OR: 0.95, 95% CI: 0.06 to 15.42, P: 0.97). The statistical analysis showed no significant difference in early (OR: 0.44, 95% CI: 0.15 to 1.33, P: 0.15), late (OR: 0.89, 95% CI: 0.41 to 1.90, P: 0.76) or total (OR: 0.68, 95% CI: 0.42 to 1.12, P: 0.13) peritonitis infections between the 2 groups, and there are no no significant difference in early (OR: 0.39, 95% CI: 0.06 to 2.36, P: 0.30), late (OR: 1.35, 95% CI: 0.78 to 2.33, P: 0.16) or total (OR: 1.20, 95% CI: 0.71 to 2.02, P: 0.17) tunnel or exit-site infections between the 2 groups. CONCLUSION: Laparoscopic catheterization and conventional open catheter placement in PD patients have unique advantages, but laparoscopic PD catheterization may be superior to conventional open catheter placement. However, this conclusion needs to be confirmed with further large-sample-size, multi-centre, high-quality RCTs.

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.

Whether Mineralocorticoid receptor antagonists (MRA) reduce mortality and cardiovascular effects of dialysis patients remains unclear. A meta-analysis was designed to investigate whether MRA reduce mortality and cardiovascular effects of dialysis patients, with a registration in INPLASY (INPLASY2020120143). The meta-analysis revealed that MRA significantly reduced all-cause mortality (ACM) and cardiovascular mortality (CVM). Patients receiving MRA presented improved left ventricular mass index (LVMI) and left ventricular ejection fraction (LVEF), decreased systolic blood pressure (SBP) and diastolic blood pressure (DBP). There was no significant difference in the serum potassium level between the MRA group and the placebo group. MRA vs. control exerts definite survival and cardiovascular benefits in dialysis patients, including reducing all-cause mortality and cardiovascular mortality, LVMI, and arterial blood pressure, and improving LVEF. In terms of safety, MRA did not increase serum potassium levels for dialysis patients with safety.

RESUMEN
OBJECTIVE: To observe the therapeutic effect of moxa fume in the treatment of chronic rhinosinusitisï¼CRSï¼ and the effect of acupuncture plus smokeless moxibustion or smoky moxibustion on the expression of thymic stromal lymphopoietin (TSLP) and pituitary adenylate cyclase activating polypeptide (PACAP) proteins in the sinus mucosal tissue in CRS mice. METHODS: Sixty male C57BL/6J mice were randomly divided into 6 groups, namely normal control, sham operation, CRS model, medication, acupuncture plus smokeless moxibustion (Acu+smokeless Moxi) and acupuncture plus smoky moxibustion (Acu+smoky Moxi) groups, with 20 mice in each group. The CRS model was established by inserting a piece of polyporous sponge filled with streptococcus pneumoniae into the maxillary sinus after operation. The mice in the sham operation group received skin incision after opening the maxillary sinus. Mice of the medication group received gavage of clarithromycin 0.103 g·kg-1·d-1 for 21 days. For mice of the Acu+smokeless Moxi and Acu +smoky Moxi groups, manual acupuncture stimulation was applied to bilateral "Zusanli" (ST36), "Shenshu" (BL23) and "Hegu" (LI4) with the needles retained for 30 min, once every other day, and on the following day, moxibustion was applied to "Guanyuan" (CV4) and "Shenque" (BL23) for 20 min, once every other day. The treatment was given for 21 days. Mice of the normal, sham operation and model groups received gavage of normal saline (200 µL/d) for 21 days. Histopathological changes of the nasal mucosa were observed after H.E. staining, the TSLP and PACAP contents and expression were determined by enzyme-linked immunosorbent assay (ELISA) and immunohistochemistry, separately. RESULTS: At the end of the treatment, mice of the model group still had symptoms of nasal obstruction and runny nose, but those of the 3 treatment groups were obviously relieved in the nasal symptoms. H.E. staining showed an obvious chronic inflammatory reaction in the sinus mucosa, uneven distribution of the mucosal epithelium and necrotic and exfoliated epithelial cells, hyperplasia of fibrous tissue in the submucosa, etc. in the model group, which were relatively milder in the medication, Acu+smokeless Moxi and Acu+smoky Moxi groups, while no obvious inflammation was found in the normal group and sham operation group. In comparison with the normal group, no significant changes were found in the expression levels of PACAP and TSLP in the sham operation group (P>0.05). The expression level of PACAP was significantly lower (P<0.05) and that of TSLP significantly higher in the model group than in the normal and sham operatin groups (P<0.05). Compared with the model group, no significant changes were found in the expression of PACAP in the medication, Acu+smokeless Moxi and Acu+smoky Moxi groups (P>0.05), and the expression of TSLP was further obviously increased in the Acu+smokeless Moxi group (P<0.01), but obviously decreased in the Acu+smoky Moxi group (P<0.01). CONCLUSION: Acupuncture combined with smoky moxibustion can down-regulate the expression of TSLP protein in the nasal sinus mucosa in CRS mice, which maybe contribute to its effect in reducing the inflammatory reaction and nasal symptoms.

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.

INTRODUCTION: Previous studies have evaluated the association between FCGR2A H131R (rs1801274) polymorphism and idiopathic (immune) thrombocytopenic purpura (ITP), but results remain inconsistent. This meta-analysis was conducted to clarify these controversies. METHODS: Literatures on PubMed/ Medline, Embase and CENTRAL databases up to September 2013 were searched by two investigators. The distributions of alleles and genotypes between cases and controls were compared by using odds ratios (ORs) and 95% confidence intervals (95% CIs). Fixed or Random-effects models were used when appropriate. RESULTS: 10 studies involving 553 patients and 1088 controls were available for this study, including 7 studies of Caucasian descendents, 2 studies of Asian descendents, and 1 study contained diverse ethnicity. In this studied overall population, we didn't found any significant association between the FCGR H131R polymorphism and the risk of ITP for all genetic models. But in the subgroup analysis, a significant association between FCGR H131R polymorphism and ITP susceptibility was observed in Caucasian population of childhood-onset group for H vs. R (OR = 1.246, 95% CI 1.021-1.522, p = 0.031), HH vs. HR + RR (OR = 1.562, 95% CI 1.145-2.129, p = 0.005), HH vs. HR (OR = 1.598, 95% CI 1.146-2.228, p = 0.006), HH vs. RR (OR = 1.484, 95% CI 1.005-2.191, p = 0.047). No significantly between-study heterogeneity was observed for all genotype models in Caucasian childhood-onset ITP subtype analysis. However, this association was not stable after sensitivity analysis. CONCLUSION: Our present meta-analysis indicated that FCGR H131R polymorphism might not be associated with risk of ITP in overall population. However, in Caucasian childhood-onset subgroup, there might be an association between FCGR2A H131R polymorphism and ITP risk, which is not robust and should be explained with caution.

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.
