Objective To study prevention and treatment for patients during the intermittent period of maintaining hemodialysis complicated by acute left heart failure. Methods The treating process of 126 examples suffered from acute left heart failure during the intermittent period of 14 225 person-time maintaining hemodialysis in 143 patients were retrospectively analyzed. Results In this case group, 0.89% suffered from acute left heart failure during the intermittent period of hemodialysis and the successful rescuing rate was 88.9%. Conclusions Applying the treatment of emergency hemodialysis, quickly filtering body fluid, the curative effect is reliable and rapid. It is one of the best ways to cure patients suffered from acute left heart failure during the intermittent period of maintaining hemodialysis. Combined with other treatments, it will be able to improve the successful rate, and ensure the sufficiency of hemodialysis. United with other steps of reducing blood pressure, such as using angiotensin converting enzyme inhibitors, angiotensin II receptor blocker, and ? receptor blocker, it is an effective countermeasure to prevent patients suffering from acute left heart failure during the intermittent period of maintaining hemodialysis, and effectively reduces its appearance as well.

Oxalate is an organic dicarboxylic acid that is a common component of plant foods.The kidneys are essential organs for oxalate excretion,but excessive oxalates may induce kidney stones.Jupiter micro-tubule associated homolog 2(JPT2)is a critical molecule in Ca2+mobilization,and its intrinsic mecha-nism in oxalate exposure and kidney stones remains unclear.This study aimed to reveal the mechanism of JPT2 in oxalate exposure and kidney stones.Genetic approaches were used to control JPT2 expression in cells and mice,and theJPT2 mechanism of action was analyzed using transcriptomics and untargeted metabolomics.The results showed that oxalate exposure triggered the upregulation of JPT2,which is involved in nicotinic acid adenine dinucleotide phosphate(NAADP)-mediated Ca2+mobilization.Tran-scriptomic analysis revealed that cell adhesion and macrophage inflammatory polarization were inhibited by JPT2 knockdown,and these were dominated by phosphatidylinositol 3-kinase(PI3K)/AKT signaling,respectively.Untargeted metabolomics indicated that JPT2 knockdown inhibited the produc-tion of succinic acid semialdehyde(SSA)in macrophages.Furthermore,JPT2 deficiency in mice inhibited kidney stones mineralization.In conclusion,this study demonstrates that oxalate exposure facilitates kidney stones by promoting crystal-cell adhesion,and modulating macrophage metabolism and in-flammatory polarization via JPT2/PI3K/AKT signaling.
