PURPOSE: ORM1-like 3 (ORMDL3) belongs to a highly conserved protein family which is anchored as transmembrane protein in the endoplasmic reticulum. Gasdermin B (GSDMB) is adjacent to ORMDL3 on chromosome 17q21.2 and belongs to the gasdermin-domain containing the protein family (GSDM family). Recent reports suggest that GSDMB and ORMDL3 are associated with asthma in several populations. However, genetic association studies that examined the association of GSDMB and ORMDL3 gene variants with asthma showed conflicting results. To assess whether combined evidence shows the association between GSDMB/ORMDL3 polymorphism and asthma. METHODS: A bibliographic search from MEDLINE identified 13 original articles using the search keywords 'GSDMB', 'ORMDL3', and 'asthma'. An updated literature-based meta-analysis involving 6,691 subjects with asthma, 9,281 control individuals, and 1,360 families were conducted. Meta-odds ratios (ORs) and 95% confidence intervals (CIs) based on the fixed effects model or the random effects model depended on Cochran's Q-statistic and I2 values. Data from case-control and TDT studies were analyzed in an allelic model using the Catmap software. RESULTS: We selected and identified 3 SNPs of ORMDL3 associated with asthma (rs8076131: OR=1.10; 95% CI, 1.02-1.20; P=0.012. rs12603332: OR=1.15; 95% CI, 1.05-1.25; P=0.002. rs3744246: OR=1.10; 95% CI, 1.02-1.17; P=0.008) and 1 SNP of GSDMB associated with asthma (rs7216389: OR=1.37; 95% CI, 1.27-1.47; P<0.01). Publication bias was estimated using modified Egger's linear regression test proposed by Harbordetal and revealed no evidence of biases. Furthermore, cumulative meta-analysis in chronological order showed the inclination toward significant association for rs7216389 and rs12603332 with continually adding studies, and the inclination toward null-significant association for rs3744246 and rs8076131. CONCLUSIONS: Moderate evidence exists for associations of the ORMDL3 rs8076131, rs12603332, and rs3744246 and GSDMB rs7216389 variants with asthma. Large sample size and representative population-based studies and TDT studies with homogeneous asthmatic patients and well-matched controls are warranted to confirm this finding.

Objective:To discuss the safety and effectiveness of del Nido cardioplegia solution in severe valvular surgery.Methods:A retrospective analysis of 138 patients of severe valvular disease underwent valve replacement or valvuloplasty in Hunan Provincial People′s Hospital between July 2019 and December 2020 was performed. According to the different cardioplegic solution used, patients were separated in two groups: the del Nido cardioplegia group (D group, n=73) and the St. Thomas cardioplegia group (C group, n=65). The perioperative clinical results of the two groups were compared to evaluate the safety and effectiveness of del Nido cardioplegia in the operation of severe valvular disease. Results:Preoperative characteristics were similar between the two groups, including gender, age, body weight, ejection fraction, and myocardial markers ( P>0.05). No statistical differences were noted in cardiopulmonary bypass time, clamp time, mechanical ventilation time, vasoactive drug use time, ICU and hospital stay time, and ejection fraction before discharge ( P>0.05). However, the times of cardioplegia perfusion [(1.33±0.47)times vs (4.08±0.48)times] and the total perfusion time [(3.96±1.41)min vs (13.15±1.46)min] in group D were lower than those in group C, while the automatic rebound rate (90.41% vs 76.92%) was higher than that in group C ( P<0.05). Both groups successfully completed the operation. There were no serious complications of important organs such as low cardiac output, brain, liver and kidney during and after the operation. There were no deaths during hospitalization, and all patients were cured and discharged. Conclusions:There was no significant difference in myocardial protection between del Nido and St. Thomas cardioplegia solution in severe valvular surgery. The application of del Nido cardioplegia could reduce the frequency of perfusions and total perfusion time.

Chaperone-mediated autophagy (CMA) is a lysosome-dependent selective degradation pathway implicated in the pathogenesis of cancer and neurodegenerative diseases. However, the mechanisms that regulate CMA are not fully understood. Here, using unbiased drug screening approaches, we discover Metformin, a drug that is commonly the first medication prescribed for type 2 diabetes, can induce CMA. We delineate the mechanism of CMA induction by Metformin to be via activation of TAK1-IKKα/β signaling that leads to phosphorylation of Ser85 of the key mediator of CMA, Hsc70, and its activation. Notably, we find that amyloid-beta precursor protein (APP) is a CMA substrate and that it binds to Hsc70 in an IKKα/β-dependent manner. The inhibition of CMA-mediated degradation of APP enhances its cytotoxicity. Importantly, we find that in the APP/PS1 mouse model of Alzheimer's disease (AD), activation of CMA by Hsc70 overexpression or Metformin potently reduces the accumulated brain Aβ plaque levels and reverses the molecular and behavioral AD phenotypes. Our study elucidates a novel mechanism of CMA regulation via Metformin-TAK1-IKKα/β-Hsc70 signaling and suggests Metformin as a new activator of CMA for diseases, such as AD, where such therapeutic intervention could be beneficial.
