ABSTRACT

【Objective】 To investigate the correlation of serum exosomal microRNA-301a (miR-301a) with cardiovascular and cerebrovascular events after peritoneal dialysis in diabetic nephropathy. 【Methods】 A total of 211 patients with diabetic nephropathy treated with peritoneal dialysis from June 2019 to June 2020 in the First Hospital Affiliated of Hebei North University were selected as study subjects. Serum exosomal miR-301a was detected by real-time fluorescence quantitative polymerase chain reaction. The patients were divided into high miR-301a group and low miR-301a group based on the median of miR-301a; the clinical data of the two groups were compared. The correlation of miR-301a with high-sensitivity C-reactive protein (hs-CRP) was analyzed by Spearman. Linear regression was applied to analyze the factors associated with the effect of miR-301a. The patients were followed up for two years. Kaplan-Meier and Log-Rank were conducted to compare the cumulative incidence of cardiovascular and cerebrovascular events between the two groups, and COX regression and restricted cubic spline were used to analyze the level-effect relationship between miR-301a and cardiovascular and cerebrovascular events after peritoneal dialysis. 【Results】 Thirty-seven cases (17.54%) of cardiovascular and cerebrovascular events occurred during follow-up. The hs-CRP level and dialysis duration were lower in low miR-301a group than in high miR-301a group (P<0.05). There was a positive correlation between miR-301a and hs-CRP (rs=0.237, P=0.001). Linear regression analysis showed that hs-CRP was independently associated with miR-301a (P<0.05). The cumulative cardiovascular and cerebrovascular event rate in low miR-301a group was 3.70% (4/108), which was lower than that in high miR-301a group [32.04% (33/103), P<0.001]. COX regression analysis showed that high serum albumin level was an independent protective factor for cardiovascular and cerebrovascular events after peritoneal dialysis in diabetic nephropathy,while high hs-CRP level and miR-301a >1.46 were independent risk factors for cardiovascular and cerebrovascular events after peritoneal dialysis in diabetic nephropathy. Restricted cubic spline fitting COX regression analysis showed a non-linear relationship between miR-301a and cardiovascular and cerebrovascular events after peritoneal dialysis in diabetic nephropathy (P<0.05). 【Conclusion】 hs-CRP is independently associated with miR-301a in diabetic nephropathy peritoneal dialysis patients. High miR-301a level suggests a high risk of cardiovascular and cerebrovascular events after peritoneal dialysis in diabetic nephropathy.

ABSTRACT

Objective:To investigate the association between serum zinc levels and convulsive brain injury in infants with mild gastroenteritis complicated with benign infantile seizures (BICE) and febrile seizures (FC).Methods:A case-control study method was conducted. 120 children with mild gastroenteritis and convulsion admitted to the First Affiliated Hospital of Hebei North University from January 2020 to January 2022 were enrolled as the research subjects. They were divided into BICE group and FC group according to the type of convulsion. The serum zinc level, the frequency and duration of convulsion, and the occurrence of convulsive brain injury in the two groups were recorded. Multivariate Logistic regression analysis was used to screen the risk factors for convulsive brain injury. The Spearman correlation method was used to analyze the association between serum zinc levels, clinical characteristics of convulsion and convulsive brain injury.Results:A total of 120 children were enrolled, of which 81 developed to BICE and 39 developed to FC during hospitalization. The serum zinc level of children in the FC group was significantly lower than that in the BICE group (μmol/L: 39.24±6.50 vs. 48.65±7.21, P < 0.01). In the BICE group and FC group, the serum zinc level in children with more than 2 convulsions was significantly lower than that in the children with one convulsion (μmol/L: 37.65±6.50 vs. 53.17±7.55 in the BICE group, and 30.27±5.58 vs. 44.16±7.57 in the FC group, both P < 0.01). Serum zinc level in children with convulsion duration ≥5 minutes was significantly lower than that in the children with convulsion duration < 5 minutes (μmol/L: 38.75±6.74 vs. 51.21±7.58 in the BICE group, and 31.08±5.46 vs. 45.19±7.25 in the FC group, both P < 0.01). Moreover, the serum zinc level of children with different convulsion frequency and duration in the FC group was significantly lower than that in the BICE group (all P < 0.01). Among the 120 children, 9 cases of convulsive brain injury occurred, and the incidence rate was 7.50%. The incidence of convulsive brain injury in the BICE group was 1.23% (1/81), which was significantly lower than 20.51% in the FC group (8/39, P < 0.01). The serum zinc level of children with convulsive brain injury was significantly lower than that of children with non-brain injury (μmol/L: 28.50±5.00 vs. 60.22±7.31, P < 0.01), and the number of convulsion was significantly higher than that of non-cerebral injury (≥ 2 convulsions: 100.00% vs. 1.80%, P < 0.01), and the duration of convulsion in children with brain injury was significantly longer than that of non-brain-injured children (convulsion duration ≥5 minutes: 100.00% vs. 11.71%, P < 0.01). Multivariate Logistic regression analysis showed that decreased serum zinc level [odds ratio ( OR) = 2.147, 95% confidence interval (95% CI) was 1.354-3.403], increased number of convulsion ( OR = 3.452, 95% CI was 1.266-9.417), and prolonged convulsion duration ( OR = 3.117, 95% CI was 1.326-7.327) were independent risk factor for convulsive brain injury in children with mild gastroenteritis and convulsion (all P < 0.05). Spearman correlation analysis showed that serum zinc level, convulsion ≥2 times, duration of convulsion ≥5 minutes and convulsion ≥2 times + convulsion duration ≥5 minutes were significantly negatively correlated with the occurrence of convulsive brain injury in FC children ( r values were -0.546, -0.517, -0.522, and -0.528, all P < 0.01). There was no significant correlation between serum zinc level, convulsion ≥2 times, convulsion duration ≥5 minutes and convulsion ≥2 times+convulsion duration ≥5 minutes and convulsive brain injury in BICE children ( r values were -0.281, -0.129, -0.201, -0.243, all P > 0.05). Conclusions:Serum zinc level is related to the characteristics of convulsive symptoms in children with mild gastroenteritis complicated with FC, and has a strong negative correlation with the occurrence of convulsive brain injury. Active targeted intervention and treatment may help reduce the incidence of brain injury in children.

ABSTRACT

Objective:To observe the changes of serum micro-inflammatory and nutritional status in elderly peritoneal dialysis patients after treatment with bifidobacterium triple viable bacteria, and the impact of Bifidobacterium triple viable bacteria treatment on the endpoint.Methods:Totally 180 elderly patients receiving peritoneal dialysis were divided into control group and observation group, with 90 cases in each.Both groups were treated on the basis of the routine treatment, the observation group was treated with oral Bifidobacterium triple viable bacteria for twelve months.Before treatment, 6 months and 12 months after treatment, fasting venous blood from the patients in the two groups were collected in the morning.The levels of serum micro-inflammatory indexes[tumor necrosis factor-α(TNF-α), interleukin-6(IL-6), interleukin-8(IL-8), C-reactive protein(CRP)]were detected by ELISA.The nutritional status and dialysis adequacy indexes[nutritional status: albumin(ALB), hemoglobin(Hb), transferrin(TRF), prealbumin(PA), calcium ion, phosphorus ion; indicators of dialysis adequacy: serum creatinine(Scr), blood uric acid(BUA), blood urea nitrogen(BUN), cystatin C(Cys-c)levels]were detected by automatic blood biochemical analyzer.After 24 months of follow-up, the occurrence of endpoint events(peritonitis, abdominal pain, malnutrition, abdominal infection, cardiovascular and cerebrovascular accidents)in the two groups was recorded.Results:After 24 months of treatment, the levels of TNF-α, IL-6, IL-8 and CRP in the two groups were lower than those before treatment, and the observation group was lower than control group[(25.7±4.0)μg/L vs.(33.6±6.0)μg/L, (2.9±0.7)ng/L vs.(4.9±1.2)ng/L, (17.0±7.2)ng/L vs.(22.8±7.9)ng/L, (4.6±0.7)mg/L vs.(6.9±1.2)mg/L]( t=10.272, 13.134, 5.040, 15.575, respectively, P<0.05 for all). After 24 months of treatment, the levels of ALB, Hb, TRF, PA and calcium ion of the two groups were higher than before treatment, and the levels of phosphorus ion were lower than before treatment, and the changes of the above indicators in observation group were more obvious than those in the control group[(45.7±5.2)g/L vs.(39.8±4.9)g/L, (72.7±8.0)g/L vs.(68.6±9.0)g/L, (4.3±1.0)g/L vs.(3.0±0.6)g/L, (321.5±29.0)mg/L vs.(297.6±25.1)mg/L, (4.9±1.3)mmol/L vs.(2.9±0.9)mmol/L, (1.3±0.9)/L vs.(1.8±0.3 mmol/L)]( t=7.737, 3.213, 9.880, 5.9 00, 11.937, 4.415, P<0.05 for all). There was no significant difference in intestinal flora between the two groups before treatment( P>0.05). After 24 months, an increase was observed in Lactobacilli and Bifidobacteria in both groups, while Enterobacteria and Enterococcus in both groups were decreased, and the changes of the above indicators in the observation group were also more obvious than those in the control group[(8.4±0.9)IgCFU/g ratio(6.4±0.9)IgCFU/g, (8.8±1.3)IgCFU/g ratio(7.9±1.3)IgCFU/g, (7.1±0.9)IgCFU/g ratio(8.0±1.1)IgCFU/g, (5.4±0.7)IgCFU/g ratio(6.9±0.9)IgCFU/g]( t=14.248, 4.339, 5.825, 12.753, P<0.05 for all). There was no significant difference in dialysis adequacy index between the two groups before treatment( P>0.05 for all). After 24 months of treatment, the levels of Scr, BUA, BUN and Cys-C in both groups decreased, and those of the observation group were lower than those of the control group[(471.5±50.5)μmol/L vs.(623.3±62.6)μmol/L, (17.5±0.5)mmol/L vs.(20.6±1.8)mmol/L, (16.4 ± 3.0)mmol/L vs.(22.5±2.0)mmol/L, (1.9±0.5)mg/L vs.(3.0±0.7)mg/L]( t=17.877, 14.976, 15.842, 11.749, P<0.05 for all). The incidence of endpoint events in the observation group was significantly lower than that in the control group(12.2% vs.2.2%, t=6.574, P<0.05 for all). Conclusions:After the treatment of Bifidobacterium triple viable bacteria in elderly peritoneal dialysis patients, the micro-inflammatory state of the patients was reduced, the nutritional status was improved, and the incidence of endpoint events was low, and has high clinical promotion and application value.

ABSTRACT

AIM: To study the role of post-hemorrhagic shock mesenteric lymph (PHSML) drainage on the balance of angiotensin-converting enzyme ( ACE) and ACE2 in the kidney.METHODS:A hemorrhagic shock model was established and then fluid resuscitation was performed to the animals in shock and shock+drainage groups, and the PHMSL was drained in shock+drainage group after fluid resuscitation.After 6 h of resuscitation, the mRNA expression of ACE, ACE2, angiotensin II (Ang II) type 1 receptor (AT1R) and Mas-related G-protein-coupled receptor (MasR), and the levels of Ang II and Ang (1-7) in the renal tissues were observed.RESULTS:Hemorrhagic shock increased the levels of ACE mRNA, AT1R mRNA and Ang II, and decreased the levels of ACE2 mRNA, MasR mRNA and Ang(1-7) in the kid-ney.PHSML drainage abolished the effect of hemorrhagic shock on ACE2 and AT1R mRNA expression.Meanwhile, PHSML drainage reduced the hemorrhagic shock-induced increases in the ratios of ACE/ACE2, Ang II/Ang(1-7) and AT1R/MasR.CONCLUSION:The PHSML drainage restores the balance of ACE/ACE2, which is beneficial to alleviate acute kidney injury following hemorrhagic shock in the mice.
