One association showed rs506121-"T" allele [within the dedicator of cytokinesis 8 (DOCK8) gene] was higher in chronic HBV infection group than that in clearance group (P = 0.002, OR = 0.77, 95% CI [0.65, 0.91]). The second association involved rs2071676-A allele within the Carbonic anhydrase (CA9) gene that was significantly elevated in chronic HBV infection group compared to the clearance group (P = 0.0003, OR = 1.35, 95% CI [1.15, 1.58]). Upon replication these gene associations would suggest the influence of DOCK8 and CA9 as potential risk genetic factors in the persistence of HBV infection.PURPOSE Modeling of hemolysis due to fluid stresses faces significant methodological challenges, particularly in geometries with turbulence or complex flow patterns. It is currently unclear how existing phenomenological blood-damage models based on laminar viscous stresses can be implemented into turbulent computational fluid dynamics simulations. The aim of this work is to generalize the existing laminar models to turbulent flows based on first principles, and validate this generalization with existing experimental data. METHODS A novel analytical and numerical framework for the simulation of flow-induced hemolysis based on the intermittency-corrected turbulent viscous shear stress (ICTVSS) is introduced. The proposed large-eddy simulation framework is able to seamlessly transition from laminar to turbulent conditions in a single flow domain by linking laminar shear stresses to dissipation of mechanical energy, accounting for intermittency in turbulent dissipation, and relying on existing power-law hemolysis to turbulent flows shows promise, but would benefit from further numerical validation and carefully designed experiments.BACKGROUND The prognosis of pneumonia in patients with advanced stage chronic kidney disease (CKD) remains unimproved for years. We attempt to develop a simple and more useful scoring system for predicting in-hospital mortality for advanced CKD patients with pneumonia. METHODS Using the Diagnosis Procedure Combination database, we identified the in-hospital adult patients both with a record of pneumonia and stage 5 or 5D CKD as a comorbidity on admission between April 1, 2012 and March 31, 2016. click here Predictive variable selection was analyzed by multivariable logistic regression analysis, stepwise method, LASSO method and random forest method, and then develop a new simple scoring system seeking for highest c-statistics combination of variables in one sample data set for model development. Finally, we compared c-statistics of univariate logistic regression about new scoring system with c-statistics about "A-DROP" in the other sample data set. RESULT We identified 8402 patients in 707 hospitals, and the total in-hospital mortality was 11.0% (437 patients) in development data set. Seven variables were selected, which includes age (male ≥ 70 years, female ≥ 75 years), respiratory failure, orientation disturbance, low blood pressure, the need of assistance in feeding or bowel control, severe or moderate thinness and CRP 200 mg/L or extent of consolidation on chest X-ray ≥ 2/3 of one lung. The c-statistics of univariate logistic regression was 0.8017 using seven variables, while that was 0.7372 using "A-DROP" CONCLUSION In advanced CKD patients, if we select appropriate variables for predicting in-hospital mortality, simple scoring system may have better discrimination than "A-DROP".Inflammatory cytokines are important protagonists in the formation of atherosclerotic plaques, triggering effects throughout the atherosclerotic vessels due to the destruction in proliferation, migration and angiogenesis of endothelial cells. In this study, we found SNHG1 is upregulated in TNF-α-treated HUVECs. We silenced SNHG1 and found it inhibited vascular endothelial cell proliferation and angiogenesis. In the other hand, exogenetic overexpression of SNHG1 promotes proliferation, migration and angiogenesis. Then we demonstrated that SNHG1 may interact directly with miR-196a to act as a miR-196a sponge. Further, MAPK6 were predicted to be the target of miR-196a. So we blocked miR-196a, which increased expression level of MAPK6, enhanced cell proliferation, migration and angiogenesis. These data indicated that SNHG1/miR-196a/MAPK6 axis may take a part in autophagy regulation in TNF-α-treated HUVECs. The subsequent rescue experiments come to the results ascertained the specificity of SNHG1/miR-196a/MAPK6 axis in regulating MAPK6. Overall, our findings demonstrate a novel mechanism by which SNHG1 overexpression protects the function of HUVECs, which may delay the progression of AS. SNHG1/miR-196a/MAPK6 axis may be of therapeutic significance in AS.Laparoscopy has emerged as a common alternative to the open approach for colorectal operations. Robotic surgery has many advantages, but cost and outcomes are an area of study. There are no randomized-controlled trials of all techniques. The present study evaluated a cohort of veterans undergoing (procto-) colectomy for benign or malignant colorectal disease. This is a single-institution retrospective review. We compared open, laparoscopic, and robotic colectomies. The primary outcome was 30-day mortality. The secondary endpoints included morbidity, operative times, estimated blood loss (EBL), length of stay (LOS), conversion rate, and the learning curve (LC). Subgroup analyses were undertaken for (1) right hemicolectomies (RHC) and (2) by specific surgeons most familiar with each approach. The cohort included 390 patients (men = 95%, White = 70.8%, BMI = 29.3 ± 6.4 kg/m2, age = 63.7 ± 10.2 years) undergoing (open = 117, laparoscopic = 168, and robotic = 105), colorectal operations for colorectal adenocarcinoma (52.8%) and benign disease. Thirty-day morbidity was similar across all techniques (open = 46.2%, laparoscopic = 42.9%, and robotic = 38.1%; NS). EBL and LOS were decreased with minimally invasive techniques compared to open. Operative time was longer in robotic, but equalized to laparoscopic after 90 cases. The learning curve was reduced to 20 when performed by the surgeon most familiar with the robot. EBL and operative time independently predicted complications for the entire cohort. The best technique for colorectal operations rests on the surgeon's experience, but minimally invasive techniques are gaining momentum over open colectomies. Robotic colectomy is emerging as a non-inferior approach to laparoscopy in terms of outcomes, while maintaining all its technical advantages.
