Objective:To explore the impact of transcranial direct current stimulation (tDCS) on ischemic stroke survivors in terms of its association with neurotrophic factors in a person′s peripheral blood.Methods:Forty ischemic stroke survivors were randomly allocated into a control group and a treatment group, each of 20. Both groups were given routine medication and rehabilitation, while the treatment group was additionally provided with 20 minutes of tDCS daily at an intensity of 2.0mA. There were 14 sessions over two weeks. The control group received sham stimulation. Before and after the experiment, both groups were assessed using the Modified Barthel Index (MBI), the Mini-mental State Examination (MMSE), the Hamilton Depression Scale (HAMD), and the Self-rated Depression Scale (SDS). The concentrations of brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) in the subjects′ peripheral blood were quantified using enzyme-linked immunosorbent assays (ELISAs).Results:Baseline comparisons revealed no significant disparities between the two groups in their average MBI, MMSE, HAMD, or SDS results, nor in their average BDNF or NGF levels. Post-treatment assessments indicated significant enhancements across these metrics within both groups. Notably, the treatment group then exhibited average MBI and MMSE scores superior to those of the control group, alongside a lower average HAMD score. Furthermore, elevated levels of BDNF [(108.20±36.96)pg/ml] and NGF [(2.90±1.03)pg/ml] were observed in the treatment group.Conclusion:tDCS appears to significantly enhance cognition, minimize symptoms of depression, and augment self-care ability after an ischemic stroke. These benefits are possibly mediated through the increase of neurotrophic factor levels.

Objective:To investigate the relationship between peritoneal thickness and baseline solute transport function in peritoneal dialysis (PD) patients, and analyze the factors affecting the function of peritoneal transport.Methods:Non-diabetic end-stage renal disease (ESRD) patients admitted to the Second Hospital of Longyan City from January 2017 to June 2019 were enrolled in this study. The thickness of the peritoneal membrane was measured by color ultrasound instrument before the peritoneal catheterization. Standard peritoneal equilibration test (PET) was performed after one month of peritoneal dialysis. The ratio of corrected creatine in 4 h dialysate to 2 h serum creatine (D/Pcr) was used as a solute baseline transport index, and according to the D/Pcr evaluation results, the patients were divided into high/high average transfer (H) group (D/Pcr≥0.65) and low/low average transfer (L) group (D/Pcr<0.65). The clinical data, peritoneal thickness and peritoneal dialysis related indicators between the two groups of patients were compared. Binary logistic regression was used to analyze the factors affecting the function of peritoneal transport.Results:The amount of peritoneal ultrafiltration in H group was significantly lower than that in L group, intraperitoneal creatinine clearance (Ccr) and peritoneal thickness were significantly higher than those in L group (both P<0.05). Pearson and Spearman correlation results showed that the thickness of peritoneal membrane positively correlated with D/Pcr ( r=0.673, P<0.05), peritoneal Ccr ( r=0.261, P<0.05), and negatively correlated with ultrafiltration of peritoneal dialysis ( r=-0.365, P<0.05). Partial correlation analysis showed that the peritoneal thickness was positively correlated with the solute transport index D/Pcr ( r=0.539, P<0.05) and the peritoneal Ccr ( r=0.338, P<0.05). Binary logistic regression results showed that peritoneal thickening was a risk factor affecting peritoneal transport function ( OR=1.175, 95% CI 1.009-1.369, P<0.05). Conclusions:There is a positive correlation between the peritoneal membrane thickness and the baseline solute transport index in patients with non-diabetic peritoneal dialysis. Peritoneal thickening is a risk factor affecting peritoneal transport function.

85%. The concentrated MCS in different amount was added to the IFN-?(100 pg/mL) and LPS (10 ng/mL) enriched culture media. The IL-12 production by monocytes was determined by the enzyme- linked immunosorbent assay(ELISA).The expression of CD14 and CD1a was analyzed by flow cytometry 5 days after the monocytes were co-cultured with MCS. Results The production of monocytic IL-12 was down-regulated by MCS in a dose dependent manner. The amount of IL-12 from monocytes decreased along with an increased dose (25-100?L) of MCS applied in the reaction. It was also observed that the differentiation from CD14 expressing monocytes to CD1a dendritic cells was impaired by MCS. The ability of MCS to inhibit the production of IL-12 by monocytes and to suppress the differentiation of monocytes to dendritic cells in vitro could be disrupted by PD98059,an ERK specific inhibitor. Conclusions MCS appears to inhibit IL-12p40 production by monocytes and inhibit differentiation of monocytes in vitro via secretion of ERK stimulating factor. The inhibitory factors in MCS and their chemical natures need further research.
