Complete remission(CR) or partial remission was regarded as effective therapy, and the cumulated remission rate was calculated.Results Seven studies involved 120 patients(73% were men) were included in our systematic review and metaanalysis. All were prospective observation cohort studies or matched-cohort studies, mainly came from two medical centers, and one study was multi-centric(four nephrology units in northern Italy). The creatinine clearance was more than 20 ml/(min·1.73 m2) and persistent proteinuria higher than 3.5 g/d for at least 6 months. All patients received treatment previously [44(36.7%) had immunosuppressive treatment]. In 12-and 24-month, 56%(95%CI, 0.47-0.65) and 68%(95%CI, 0.41-0.87) patients could reach remission, while 15%(95%CI, 0.09-0.23) and 20%(95%CI, 0.12-0.32) patients could reach CR. The reduction in proteinuria was gradual and obvious, paralleled with upward trend of serum albumin level and decreasing serum cholesterol level. Renal functions were stable. Relapses happened in 24 months were around 8%. RTX related adverse events were mild and were mostly infusion-related reactions.Conclusions RTX treatment in IMN was efficient, well tolerated and safe. More than 60% patients can reach partial remission or CR in 24 months, and relapse is rare. Adverse events of RTX are mostly infusion-related reactions and generally mild.展开更多

The prerequisites for the appearance of CSSS are both a patent left internal mammary artery (LIMA) graft and severe stenosis of the left subclavian artery (LSA). However,LSA is often overlooked in the diagnostic evaluation of patients with angina,who have underwent coronary artery bypass grafting (CABG). We report an unusual case of non-ST-segment elevation myocardial infarction (NSTEMI) caused by subtotal occlusion of proximal LSA.展开更多

文摘In this study,the impacts of egg consumption on mice model of metabolic syndrome(Met S)were comparatively investigated.Mice were divided into five groups(n=8):normal diet group(ND),high-fat diet group(HFD),HFD with whole egg group(WE),HFD with free-yolk egg substitute group(YFES),and HFD with lovastatin group(Lov).Main biochemical indexes and a non-targeted lipidomic analysis were employed to insight the lipid profile changes in serum.It was revealed that WE could significantly improve serum biochemical indexes by reducing body weight,low-density lipoprotein cholesterol(LDL-C)and total cholesterol(TC),while increasing high-density lipoprotein cholesterol.YFES exhibited remarkably better performance in increasing phosphatidylglycerol and phosphatidic acids,while decreasing phosphatidylinositol than WE.A total of 50 differential lipids biomarkers tightly related to glycerophospholipids metabolism were screened out.Carnitine C18:2 and C12:1,SM(d18:0/12:0),and SM(d18:1/14:1)were significantly upregulated in YFES compared to WE.YFES reduced expression of SREBP-1c and Cpt1a,while did not affect the expression of PPAR-α.Sphingomyelin biomarkers were positively related to the TC(|r|>0.6),while PPAR-αwas negatively correlated with triglyceride and LDL-C levels.To sum up,YFES attenuated HFD-induced Met S by improving the serum phospholipids,which account for its modulation of glycerophospholipid metabolism.

文摘Sugarcane leaves-derived polyphenols(SLP)have been demonstrated to have diverse health-promoting benefits,but the mechanism of action has not been fully elucidated.This study aimed to investigate the anti-metabolic disease effects of SLP and the underlying mechanisms in mice.In the current study,we prepared the SLP mainly consisting of three flavonoid glycosides,three phenol derivatives,and two lignans including one new compound,and further demonstrated that SLP reduced body weight gain and fat accumulation,improved glucose and lipid metabolism disorders,ameliorated hepatic steatosis,and regulated short-chain fatty acids(SCFAs)production and secondary bile acids metabolism in ob/ob mice.Notably,SLP largely altered the gut microbiota composition,especially enriching the commensal bacteria Akkermansia muciniphila and Bacteroides acidifaciens.Oral gavage with the above two strains ameliorated metabolic syndrome(MetS),regulated secondary bile acid metabolism,and increased the production of SCFAs in high-fat diet(HFD)-induced obese mice.These results demonstrated that SLP could be used as a prebiotic to attenuate MetS via regulating gut microbiota composition and further activating the secondary bile acids-mediated gut-adipose axis.

文摘Metabolic syndrome(Met S)is a chronic disease associated with the disturbance of gut microbiota homeostasis.Metabolites derived from gut microbes play essential roles in Met S prevention and therapy.Here,we focused on the inhibitory effect of the extract of millet bran protein(EMBP)on a high-fat diet(HFD)-induced Met S,aiming to identify gut microbiota and their metabolites that involve in the anti-Met S activity of EMBP.The obesity,chronic inflammation,insulin resistance in Met S mouse models were abolished after EMBP treatment.The protective mechanism of EMBP against HFD-induced Met S may depend on improved gut barrier function.Using microbiome analysis,we found that EMBP supplementation improved gut microbiome dysbiosis in Met S mice,specifically upregulating Bacteroides acidifaciens.The fecal microbiota transplantation(FMT)also demonstrated this phenomenon.In addition,metabolomic analysis showed that EMBP mediates metabolic profiling reprogramming in Met S mice.Notably,a microbiota-derived metabolite,gamma-aminobutyric acid(GABA),is enriched by EMBP.In addition,exogenous GABA treatment produced a similar protective effect to EMBP by improving NRF2-dependent gut barrier function to protect HFDinduced Met S.The results suggest that EMBP suppress host Met S by remodeling of gut microbiota as an effective candidate for next-generation medicine food dual purpose dietary supplement to intervene in MetS.

文摘Objective To investigate the efficacy and safety of rituximab(RTX) in the treatment of idiopathic membranous nephropathy(IMN) with nephrotic syndrome with a systematic review and meta-analysis.Methods Pub Med, Embase, Cochrane Library and Clinical Trials(December 2016) were searched to identify researches investigating the treatment of RTX in adult patients with biopsy-proven IMN. Complete remission(CR) or partial remission was regarded as effective therapy, and the cumulated remission rate was calculated.Results Seven studies involved 120 patients(73% were men) were included in our systematic review and metaanalysis. All were prospective observation cohort studies or matched-cohort studies, mainly came from two medical centers, and one study was multi-centric(four nephrology units in northern Italy). The creatinine clearance was more than 20 ml/(min·1.73 m2) and persistent proteinuria higher than 3.5 g/d for at least 6 months. All patients received treatment previously [44(36.7%) had immunosuppressive treatment]. In 12-and 24-month, 56%(95%CI, 0.47-0.65) and 68%(95%CI, 0.41-0.87) patients could reach remission, while 15%(95%CI, 0.09-0.23) and 20%(95%CI, 0.12-0.32) patients could reach CR. The reduction in proteinuria was gradual and obvious, paralleled with upward trend of serum albumin level and decreasing serum cholesterol level. Renal functions were stable. Relapses happened in 24 months were around 8%. RTX related adverse events were mild and were mostly infusion-related reactions.Conclusions RTX treatment in IMN was efficient, well tolerated and safe. More than 60% patients can reach partial remission or CR in 24 months, and relapse is rare. Adverse events of RTX are mostly infusion-related reactions and generally mild.
文摘Shang Han Lun is one of the most famous and important traditional medical books in China,so many translation versions of it have emerged.Based on the comparison of examples taken from two of these translation versions,Young Jie De ' s Shang Han Lun Explained and Huang Hai s Introduction to Treatise on Exogenous Febrile Disease,the paper points out that Nida s Functional Equivalence Theory provides a new idea for the translation of Disease and Syndrome Terms in TCM that literal translation,liberal translation and transliteration can be adopted appropriately to make readers of translation versions understand TCM accurately and easily.
文摘Frailty is an issue of paramount importance for cardiologists,because of the aging of patients admitted to hospital for acute coronary syndrome(ACS)and the straight relationship between aging and frailty.Several tools have been provided in this setting,in order to objectively assess frailty status,but important questions are still unsolved.There are conflicting data about a unique definition of frailty in subjects with cardiovascular diseases,the timing to perform a frailty evaluation in the context of an acute myocardial infarction,the mean to assess frailty in these patients and the usefulness of the information derived from the frailty assessment.Frailty results from the analysis of several items and a multidomain evaluation including laboratory values,clinical data and physical performance assessment is required for a comprehensive frailty assessment.However,regardless of the frailty tool,the prevalence of frailty in older ACS patients is high and it could add important information to the decision-making process about invasive strategy,the multivessel disease management,dual antiplatelet therapy and secondary prevention programs.The present overview tries to summarize the current knowledge about the definition and prevalence of frailty in older adults admitted to hospital for ACS,suggesting how frailty assessment may improve the management of older ACS patients.
文摘There are important sex-related differences in elderly patients with acute coronary syndrome(ACS).Women are older,more frequently frail,and present more comorbidities than men.Atypical symptoms at presentation are also more common in female patients,they are leaded to a delayed diagnosis and treatment.Coronary angiography and subsequent revascularization are frequently underused in elderly women and they tend to receive less guidelines-recommended therapies.The prognosis in elderly frail women with ACS is poor,and it is with high mortality and readmissions rates.Bleeding is recurrent ischemic events in which it is more frequent in women than in men.Recovery time might be long,and a multidisciplinary approach is desirable to improve prognosis and quality of life.Further studies are needed in order to clarify the benefit of the different therapies in the group of frail women,and this is particularly true for revascularization,as scientific evidence in this group is very scarce.
文摘With population ageing and rise of life expectancy,a progressively increasing proportion of patients presenting with an acute coronary syndrome(ACS)are older adults,including those at extreme chronological age.Increasing amounts of data,including randomized clinical trials,have shown that the benefits of an early revascularization are maintained also at very old age,resulting in improved outcome after an acute coronary event.On the contrary,the optimal antiplatelet therapy(APT)remains unclear in these patients,because of both safety and efficacy concerns.Indeed,age-related multiple organ dysfunction and high prevalence of comorbidities may on the one hand reduce the therapeutic effects of administered drugs;on the other hand,it leads to increased vulnerability to drug toxicity and side effects.Therefore,management of APT is particularly challenging in elderly patients because of higher risk of both ischemic and bleeding events.The aim of the present paper is to review the current evidence,gaps in knowledge and ongoing research regarding APT in the setting of an ACS in elderly and very elderly patients,and in those with significant comorbidities including chronic kidney disease,diabetes mellitus and frailty.

文摘Coronary subclavian steal syndrome (CSSS) has been recognized lately as an unusual clinical entity,giving rise to angina but rarely causing an acute coronary syndrome (ACS). The prerequisites for the appearance of CSSS are both a patent left internal mammary artery (LIMA) graft and severe stenosis of the left subclavian artery (LSA). However,LSA is often overlooked in the diagnostic evaluation of patients with angina,who have underwent coronary artery bypass grafting (CABG). We report an unusual case of non-ST-segment elevation myocardial infarction (NSTEMI) caused by subtotal occlusion of proximal LSA.
