These included the Cochrane Library, Wanfang Database, PubMed, CNKI, Embase, and Clinical Trials. The search encompassed studies published from the inception of the databases to March 2024. Randomized controlled studies meeting the inclusion criteria were assessed for bias using the Cochrane risk of bias assessment tool. Data were analyzed using Review Manager 5.4, with relative risk (RR) as the effect indicator. Depending on the heterogeneity of the studies, either a fixed-effects model or a random-effects model was employed to combine effect sizes. Seven studies met the inclusion criteria. Compared with ARB drugs, sacubitril/valsartan showed a reduction in the deterioration of renal function (RR = 0.70, 95% CI: 0.44–1.12, P = 0.14) and acute renal function injury (RR = 0.77, 95% CI: 0.59–1.00, P = 0.05). The risk of end-stage renal disease was also lower (RR = 0.53, 95% CI: 0.30–0.96, P = 0.16). For serum creatinine levels greater than 2.5 mg/dL, the RR was 0.88 (95% CI: 0.68–1.15, P = 0.37). For a reduction in eGFR of more than 25%, the RR was 0.89 (95% CI: 0.57–1.41, P = 0.63). The incidence of serum potassium levels greater than 5.5 mmol/L was not significantly different between the groups (RR = 1.23, 95% CI: 0.86–1.75, P = 0.26), nor was the incidence of serum potassium levels greater than 6.0 mmol/L (RR = 1.06, 95% CI: 0.58–1.93, P = 0.86). However, the incidence of eGFR decreasing by more than 50% was significantly reduced (RR = 0.58, 95% CI: 0.34–0.99, P < 0.05). In conclusion, sacubitril/valsartan demonstrated a protective effect on the kidneys, effectively reducing the risk of renal deterioration and presenting a potential alternative to ARB drugs.展开更多

文摘Objective Traditional Chinese medicine exhibits positive therapeutic effects as a primary or adjunctive treatment for diabetic nephropathy(DN).This study aimed to evaluate the impact and mechanism of action of Xiaoke decoction(XKD),a traditional Chinese medicine,on renal function in DN rats.Methods A rat model of DN was established,and the rats were divided into five groups(n=7 per group):normal control group(NC),DN model group(DN),low-dose XKD treatment group(DN+XKD-L,1.5 g/kg/d),high-dose XKD treatment group(DN+XKD-H,6 g/kg/d),and cyclooxygenase-2(COX-2)inhibitor(NS398)treatment group(DN+NS398,8 mg/kg/d).Medications were administered via gavage for 12 consecutive weeks,while equal volumes of normal saline were given to the NC and DN groups.A glucometer was used to detect changes in blood glucose(BG).Enzyme-linked immunosorbent assay(ELISA)and an automatic biochemical analyzer were employed to measure levels of insulin,serum creatinine(Scr),blood urea nitrogen(BUN),triglyceride(TG),total cholesterol(TC),high-density lipoprotein(HDL),low-density lipoprotein(LDL),and 24-h urine protein quantity(UP/24 h)in rats.Renal tissue sections from different treatment groups were prepared,with tissue lesions examined via periodic acid-Schiff(PAS)and hematoxylin–eosin(HE)staining.Tissue inflammation and lipid deposition were evaluated using ELISA and Oil Red O staining.Immunohistochemistry and Western blotting were used to detect changes in the expression levels of COX-2 and low-density lipoprotein receptor(LDLr)in tissues,and to clarify the regulatory mechanism of XKD on renal function in DN rats.Results XKD,particularly at the high dose(XKD-H,6 g/kg/d),significantly reduced BG,insulin levels,renal weight ratio,Scr,BUN,and UP/24 h in DN rats.DN rats showed significant renal lesions,and XKD gavage(especially XKD-H)markedly improved these pathological changes.In DN rats,XKD significantly decreased the protein expression levels of COX-2 and LDLr,downregulated the levels of inflammatory factors and lipid factors,reduced lipid deposition in renal tissues,and ameliorated structural abnormalities in glomeruli,basement membranes,and renal tubules.Conclusions XKD alleviates renal tissue damage by regulating the COX-2-mediated LDLr pathway,thereby reducing the release of inflammatory factors and lipid accumulation in DN rats and protecting renal function.Graphical Abstract XKD improves renal function in streptozotocin(STZ)-induced DN rats by regulating the COX-2-mediated LDLr pathway,reducing inflammatory factors and lipid deposition,and alleviating renal tissue damage.
文摘BACKGROUND Patients with chronic hepatitis B(CHB)require long-term antiviral therapy.The effects of different antiviral drugs on kidney function are unclear.There is a lack of effective markers for monitoring early renal impairment.AIM To investigate the rate of abnormal renal function index and related potential hazards in patients with CHB.METHODS Clinical data of patients with CHB with urinaryβ2-microglobulin(β2-M)detec-tion,including demographic characteristics,hepatitis B virus(HBV)DNA,serum liver function(alanine aminotransferase,aspartate aminotransferase,total bilirubin,direct bilirubin),serum renal function(urea nitrogen,creatinine),blood lipid index(high density lipoprotein,low density lipoprotein,cholesterol,trigly-ceride),liver imaging,and other routine tests were retrospectively collected.The normal level of urinaryβ2-M and estimated glomerular filtration rate(eGFR)is defined as<0.173 mg/L and≥90 mL/min/1.73 m^(2),retrospectively.The pro-portion of patients with abnormal renal function index and related risk factors were analyzed.RESULTS A total of 500 patients with CHB were enrolled;these patients were aged 44.7±10.8 years,67.2%(336/500)were male,57.2%(286/500)were treated with anti-viral drugs,and 52.2%(261/500)had an HBV-related family history.In total,28.8%(144/500)of patients had fatty liver,35.0%(175/500)had liver fibrosis,and 13.2%(66/500)had cirrhosis.The proportion of patients with eGFR<90 mL/min/1.73 m^(2) was 43.2%(216/500),and the abnormal rate of urinaryβ2-M was 56.2%(281/500).There was no significant difference in the abnormal rate of urinaryβ2-M between the untreated group and the antiviral treated group(54.2%vs 57.7%;P=0.25).The abnormal rate ofβ2-M after long-term entecavir treatment(more than 1 year)was 54.6%(89/163).In the treatment group,56.4%(92/163)of patients with eGFR≥90 mL/min/1.73 m^(2) had abnormal urinaryβ2-M.CONCLUSION In patients with CHB,a higher proportion had greater urinaryβ2-M levels than eGFR for renal injury.Male patients should pay more attention to renal function and use antiviral regimens with a renal safety profile.
文摘BACKGROUND Atrial fibrillation(AF)is a prevalent cardiac arrhythmia associated with significant morbidity and mortality,particularly in patients with concomitant renal dysfunction.Anticoagulation therapy reduces the risk of thromboembolic complications in AF but presents challenges in patients with renal impairment due to altered pharmacokinetics and increased bleeding risk.AIM To support clinicians in navigating the complexities of anticoagulation in this high-risk population,ensuring optimal outcomes.METHODS The present review followed PRISMA guidelines.Data extraction was conducted using a standardized template that captured key study characteristics:Population demographics,renal function metrics,anticoagulant dosing strategies,and primary and secondary outcomes.For quality assessment,we employed the Cochrane Risk of Bias 2.0 tool for randomized controlled trials.Observational studies were appraised using the Newcastle-Ottawa Scale.RESULTS We analyze data from 16 studies to provide recommendations on optimal anticoagulation strategies,balancing thrombotic and bleeding risks.Current evidence supports the preferential use of apixaban in moderate chronic kidney disease and cautiously in end-stage renal disease,emphasizing the importance of individualized therapy.CONCLUSION The management of anticoagulation in AF patients with renal dysfunction is challenging but critical for reducing stroke risk.

文摘Gauss radial basis functions(GRBF)are frequently employed in data fitting and machine learning.Their linear independence property can theoretically guarantee the avoidance of data redundancy.In this paper,one of the main contributions is proving this property using linear algebra instead of profound knowledge.This makes it easy to read and understand this fundamental fact.The proof of linear independence of a set of Gauss functions relies on the constructing method for one-dimensional space and on the deducing method for higher dimensions.Additionally,under the condition of preserving the same moments between the original function and interpolating function,both the interpolating existence and uniqueness are proven for GRBF in one-dimensional space.The final work demonstrates the application of the GRBF method to locate lunar olivine.By combining preprocessed data using GRBF with the removing envelope curve method,a program is created to find the position of lunar olivine based on spectrum data,and the numerical experiment shows that it is an effective scheme.

文摘To evaluate the effects of sacubitril/valsartan and ARB on renal function in patients with and without heart failure, we conducted a comprehensive literature search using both Chinese and English databases. These included the Cochrane Library, Wanfang Database, PubMed, CNKI, Embase, and Clinical Trials. The search encompassed studies published from the inception of the databases to March 2024. Randomized controlled studies meeting the inclusion criteria were assessed for bias using the Cochrane risk of bias assessment tool. Data were analyzed using Review Manager 5.4, with relative risk (RR) as the effect indicator. Depending on the heterogeneity of the studies, either a fixed-effects model or a random-effects model was employed to combine effect sizes. Seven studies met the inclusion criteria. Compared with ARB drugs, sacubitril/valsartan showed a reduction in the deterioration of renal function (RR = 0.70, 95% CI: 0.44–1.12, P = 0.14) and acute renal function injury (RR = 0.77, 95% CI: 0.59–1.00, P = 0.05). The risk of end-stage renal disease was also lower (RR = 0.53, 95% CI: 0.30–0.96, P = 0.16). For serum creatinine levels greater than 2.5 mg/dL, the RR was 0.88 (95% CI: 0.68–1.15, P = 0.37). For a reduction in eGFR of more than 25%, the RR was 0.89 (95% CI: 0.57–1.41, P = 0.63). The incidence of serum potassium levels greater than 5.5 mmol/L was not significantly different between the groups (RR = 1.23, 95% CI: 0.86–1.75, P = 0.26), nor was the incidence of serum potassium levels greater than 6.0 mmol/L (RR = 1.06, 95% CI: 0.58–1.93, P = 0.86). However, the incidence of eGFR decreasing by more than 50% was significantly reduced (RR = 0.58, 95% CI: 0.34–0.99, P < 0.05). In conclusion, sacubitril/valsartan demonstrated a protective effect on the kidneys, effectively reducing the risk of renal deterioration and presenting a potential alternative to ARB drugs.

文摘Spinal cord injury represents a severe form of central nervous system trauma for which effective treatments remain limited.Microglia is the resident immune cells of the central nervous system,play a critical role in spinal cord injury.Previous studies have shown that microglia can promote neuronal survival by phagocytosing dead cells and debris and by releasing neuroprotective and anti-inflammatory factors.However,excessive activation of microglia can lead to persistent inflammation and contribute to the formation of glial scars,which hinder axonal regeneration.Despite this,the precise role and mechanisms of microglia during the acute phase of spinal cord injury remain controversial and poorly understood.To elucidate the role of microglia in spinal cord injury,we employed the colony-stimulating factor 1 receptor inhibitor PLX5622 to deplete microglia.We observed that sustained depletion of microglia resulted in an expansion of the lesion area,downregulation of brain-derived neurotrophic factor,and impaired functional recovery after spinal cord injury.Next,we generated a transgenic mouse line with conditional overexpression of brain-derived neurotrophic factor specifically in microglia.We found that brain-derived neurotrophic factor overexpression in microglia increased angiogenesis and blood flow following spinal cord injury and facilitated the recovery of hindlimb motor function.Additionally,brain-derived neurotrophic factor overexpression in microglia reduced inflammation and neuronal apoptosis during the acute phase of spinal cord injury.Furthermore,through using specific transgenic mouse lines,TMEM119,and the colony-stimulating factor 1 receptor inhibitor PLX73086,we demonstrated that the neuroprotective effects were predominantly due to brain-derived neurotrophic factor overexpression in microglia rather than macrophages.In conclusion,our findings suggest the critical role of microglia in the formation of protective glial scars.Depleting microglia is detrimental to recovery of spinal cord injury,whereas targeting brain-derived neurotrophic factor overexpression in microglia represents a promising and novel therapeutic strategy to enhance motor function recovery in patients with spinal cord injury.
文摘BACKGROUND End-stage renal disease(ESRD)is associated with a multitude of physical,psychological,and social health challenges,including a profound impact on sexual and reproductive health.Among males with ESRD,erectile dysfunction(ED)is highly prevalent due to factors such as underlying comorbidities,including diabetes and hypertension,and the physiological effects of long-term dialysis.Kidney transplantation(KTx)has been proposed as a potential intervention to mitigate the effects of ED by restoring renal function and improving hormonal balance.However,the evidence surrounding the effectiveness of KTx in improving sexual function,specifically erectile function(EF),remains inconclusive.This systematic review and meta-analysis aim to evaluate the effects of KTx on sexual dysfunction(SexDys),particularly ED,in male ESRD patients.AIM To evaluate the benefits and potential harms of KTx compared to other forms of renal replacement therapy in improving EF in adult males with ESRD,assessed using the international index of EF(IIEF),to survey the prevalence of SexDys in this population,and to assess the correlation between various factors and SexDys through regression analysis.METHODS A systematic search of PubMed,EMBASE,Cochrane Library,Scopus,Clinical-Trials.gov,and Google Scholar was conducted,following the PRISMA 2020 guidelines.Prospective and retrospective cohort studies,as well as cross-sectional studies assessing EF pre-and post-transplantation,were included.These studies used validated tools such as the IIEF to measure EF.Meta-analyses were performed using a random-effects model to estimate standardized mean differences(SMD)and hazard ratios(HR)with 95%confidence intervals(CI).Heterogeneity was assessed using the I²statistic,and publication bias was evaluated with a funnel plot and the Egger’s test.RESULTS A total of 2419 studies were identified,with 362 abstracts screened and 193 full-text articles reviewed.Ultimately,11 studies were included for qualitative analysis and 7 for quantitative synthesis.The random effects model for SMD yielded a combined estimate of 0.43(95%CI:-0.20-1.07),indicating a small but non-significant improvement in EF post-transplantation.The heterogeneity across studies was substantial(I²=90%),reflecting significant variability in outcomes.Subgroup analysis showed greater improvements in EF among living-donor transplant recipients compared to those receiving organs from deceased donors.Despite this trend,the overall result for changes in EF was not statistically significant(P=0.15).Additionally,the combined HR from the meta-analysis was 2.87(95%CI:1.76-4.69),suggesting that KTx significantly increases the likelihood of improved EF,though variability between studies persisted(I²=63%).CONCLUSION While KTx offers some promise for improving EF in male ESRD patients,the overall evidence remains inconclusive due to high heterogeneity between studies and a lack of statistical significance in the combined results.Despite this,individual studies suggest that KTx may lead to significant improvements in EF for certain subgroups,particularly living-donor recipients.Future research should focus on larger,well-designed cohort studies with standardized outcome measures to provide more definitive conclusions.Addressing SexDys as part of routine care for ESRD patients undergoing KTx is crucial to improving their overall quality of life.However,adjunct therapies such as phosphodiesterase type 5 inhibitors may be necessary for those who do not experience adequate improvements post-transplantation.

文摘Elaidic acid(EA)is a typical trans fatty acid(TFA)that emerges during the processing of various fatty foods.In this study,we found that EA induced renal injury with necroptosis.Pretreatment with a reactive oxygen species(ROS)inhibitor and a RIPK3 inhibitor alleviated EA-induced necroptosis.The data indicated that EA induced renal necroptosis through ROS/RIPK3/MLKL pathway.In mechanistic studies,we explored how EA induced ROS production.Results indicated that EA caused mitochondrial damage by testing MMP,MFN1,VDAC,and FIS1.Further,EA suppressed mitophagy by testing the levels of LC3,p62,PINK1,Parkin,colocalization of LC3 and Mito-Tracker Red.Mitophagy is a process of selective degradation of damaged mitochondria.A large number of damaged mitochondria couldn't be cleared by mitophagy in time,which increased ROS levels in renal cells.Pretreatment with a mitophagy activator decreased EA-induced ROS levels and mitochondrial damage.Taken together,our data identified that EA induced renal necroptosis by destroying mitochondria and inhibiting mitophagy,thereby activating the ROS/RIPK3/MLKL pathway.

文摘Background:The traditional method of heterotopic abdominal heart transplantation(HTx)involves crossclamping the inferior vena cava,which inevitably leads to bilateral lower limb ischemia(LI).This study first aimed to investigate the impact of LI on renal function in rats subjected to unilateral nephrectomy(UNx).Second,a modified method utilizing renal vessel-assisted anastomosis in rats with left UNx was compared with the traditional method for abdominal HTx.Methods:Male Sprague-Dawley rats were utilized as subjects for both experimental phases.In experiment 1,the animals were divided into four groups:sham operation group;LI group-rats undergoing occlusion of the abdominal aorta and vena cava below the renal vessels;UNx group-rats with left UNx;and LI+UNx group.All operated animals were monitored for up to 7 days for biochemical markers,renal histopathology,and survival rates.In experiment 2,we introduced the renal vessel-assisted method as the experimental group and compared it against the traditional method as the control within rat heterotopic HTx models.We assessed operative characteristics,echocardiography results,histological findings,and graft survival.Results:First,LI resulted in acute kidney dysfunction characterized by a decrease in 7day survival rates and creatinine clearance rates in both the LI and LI+UNx groups compared to the sham operation and UNx groups.Particularly,histopathological damage in the kidney and liver did not exhibit significant effects during this period.Second,the implementation of the renal vessel-assisted method significantly reduced bleeding volume at suture sites and enhanced the 7day survival rate compared to the traditional method.Conclusion:Acute kidney injury was induced by LI postoperation in treated rats.The renal vessel-assisted method demonstrated its effectiveness as a superior alternative that mitigates complications associated with the traditional method.
文摘BACKGROUND Anxiety,depression,and other negative emotions are common among patients with chronic renal failure(CRF).Analyzing the factors related to negative emotions is necessary to provide targeted nursing care.AIM To explore the correlations among life satisfaction,pleasure levels,and negative emotions in patients with CRF.METHODS One hundred patients with CRF who received therapy at the First Affiliated Hospital of Jinzhou Medical University between December 2022 and February 2025 were included.The Depression,Anxiety,and Stress Scale(DASS-21),Satisfaction with Life Scale(SWLS),and Temporal Experience of Pleasure Scale(TEPS)were used to evaluate negative emotions,life satisfaction,and pleasure level,respectively.Pearson’s correlation coefficient analyzed the correlation between life satisfaction,pleasure level,and negative emotions.Linear regression analysis identified the factors affecting negative emotions.RESULTS The average DASS-21 score among patients with CRF was 51.90±2.30,with subscale scores of 17.90±1.50 for depression,18.53±1.18 for anxiety,and 15.47±2.36 for stress,all significantly higher than the domestic norm(P<0.05).The average SWLS score was 22.17±4.90.Correlation analysis revealed a negative correlation between the SWLS and total DASS-21 scores(P<0.05),but not with the individual depression,anxiety,or stress dimensions.The average TEPS score was 67.80±8.34.TEPS scores were negatively correlated with the DASS-21 score and the stress dimension(P<0.05),but not with depression or anxiety.Linear regression analysis showed that TEPS scores significantly influenced DASS-21 scores(P<0.05).CONCLUSION Patients with CRF experience high levels of negative emotions,which are negatively correlated with life satisfaction and pleasure.Furthermore,pleasure level had an impact on negative emotions.
