Electromagnetic stimulation is an important neuromodulation technique that modulates the electrical activity of neurons and affects cortical excitability for the purpose of modulating the nervous system. The phenomenon of inverse stochastic resonance is a response mechanism of the biological nervous system to external signals and plays an important role in the signal processing of the nervous system. In this paper, a small-world neural network with electrical synaptic connections was constructed, and the inverse stochastic resonance of the small-world neural network under electromagnetic stimulation was investigated by analyzing the dynamics of the neural network. The results showed that: the Levy channel noise under electromagnetic stimulation could cause the occurrence of inverse stochastic resonance in small-world neural networks; the characteristic index and location parameter of the noise had significant effects on the intensity and duration of the inverse stochastic resonance in neural networks; the larger the probability of randomly adding edges and the number of nearest neighbor nodes in small-world networks, the more favorable the anti-stochastic resonance was; by adjusting the electromagnetic stimulation parameters, a dual regulation of the inverse stochastic resonance of the neural network can be achieved. The results of this study provide some theoretical support for exploring the regulation mechanism of electromagnetic nerve stimulation technology and the signal processing mechanism of nervous system.

Objective:To analyze the relationship between plasma uranium concentration and renal injury.Methods:A case-control study was conducted in Hunan province, involving 102 renal injury cases and 102 matched controls. The association between plasma uranium concentration and renal injury was analyzed using conditional logistic regression models, and the dose-response relationship was analyzed through restricted cubic spline regression. The linear regression model and Spearman correlation were used to analyze the association between plasma uranium concentration and renal injury indicators.Results:The median of plasma uranium concentration was 8.94 ng/L in all subjects and 10.19 ng/L in the case group. The plasma uranium may be a risk factor for renal injury, with a dose-response relationship between the both representing nonlinear association ( χ2=5.15, P<0.05). The risk of renal injury was 4.21 times higher in the group exposed to highest uranium concentration than that in the group exposed to lowest uranium concentration. Plasma uranium concentration was closely related to glomerular filtration rate, serum creatinine and β 2-microglobulin ( r=0.211, -0.142, 0.195, P<0.05). Conclusions:The plasma uranium concentration is significantly associated with the renal injury, which may provide epidemiology evidence for the prevention of renal injury.

Electroconvulsive therapy (ECT) is an interventional technique capable of highly effective neuromodulation in major depressive disorder (MDD), but its antidepressant mechanism remains unclear. By recording the resting-state electroencephalogram (RS-EEG) of 19 MDD patients before and after ECT, we analyzed the modulation effect of ECT on the resting-state brain functional network of MDD patients from multiple perspectives: estimating spontaneous EEG activity power spectral density (PSD) using Welch algorithm; constructing brain functional network based on imaginary part coherence (iCoh) and calculate functional connectivity; using minimum spanning tree theory to explore the topological characteristics of brain functional network. The results show that PSD, functional connectivity, and topology in multiple frequency bands were significantly changed after ECT in MDD patients. The results of this study reveal that ECT changes the brain activity of MDD patients, which provides an important reference in the clinical treatment and mechanism analysis of MDD.

Background Exposure to uranium can result in multi-organ toxicity in humans. Some experimental studies have shown that uranium presents a damaging effect on liver, but no relevant population studies have been reported. Objective To investigate a potential association of plasma uranium exposure with liver injury. Methods The inhabitants of two representative areas of heavy metal pollution in northern and southern Hunan were selected as the research subjects. A total of 740 participants were recruited through 1∶1 paired case-control design based on a pre-determined diagnostic criterion for liver injury (defined as two or more anomalies among alanine aminotransferase, aspartate aminotransferase, and total bilirubin in the health examination) and the principle of case-control comparability. Information such as general demographic characteristics and medical history were collected through questionnaires and physical examination. Plasma uranium and liver function were determined by laboratory tests. Spearman correlation was applied to assess the association between plasma uranium concentration and liver injury indexes, and restricted cubic spline model was used to evaluate the dose-response relationship between plasma uranium concentration and liver injury. The participants were divided into four groups from Q1 to Q4 according to the quartile values of plasma uranium concentration of the control group after natural logarithmic transformation (with the Q1 group as the reference group), and the association between plasma uranium concentration and liver injury was evaluated by conditional logistic regression. Results The plasma uranium level in M (P25, P75) of the case group was 10.89 (6.78-18.53) ng·L−1, higher than that in the control group, 9.26 (5.01-14.38) ng·L−1 (P<0.001). The results of Spearman correlation analysis showed that alanine aminotransferase and aspartate aminotransferase were positively correlated with plasma uranium level (rs=0.138, rs=0.167; P<0.001). The restricted cubic spline model showed that the risk of liver injury increased with the increase of plasma uranium concentration (overall effect P<0.001). After adjusting for confounding factors such as gender, age, smoking, alcohol consumption, and prevalence of hypertension and hyperlipidemia, the results of conditional logistic regression analysis showed that the risks of liver injury in the Q2 group, the Q3 group, and the Q4 group were 2.043 (95%CI: 1.135-3.680), 2.246 (95%CI: 1.238-4.075), and 3.536 (95%CI: 1.955-6.397) times higher than that of the Q1 group respectively. Conclusion Plasma uranium exposure is associated with liver injury. This study is the first to provide population-level evidence of such an association.

OBJECTIVE:To stud y the effects of “green removing ”processing technology of fresh fruit of Schisandra chinensis after harvested on the quality of medicinal material ,and to provide new ideas for the scientific and rational processing of Chinese medicinal material. METHODS :Fifteen fresh fruits of S. chinensis were used as samples ,with 3 samples in each group. The sample were processed preliminarily by 5 methods,such as drying at 50 ℃,drying in the sun ,drying at 50 ℃ after“green removing”processing with microwave ,drying at 50 ℃ after“green removing ”processing with blanching ,drying at 50 ℃ after “green removing ”processing with steaming. HPLC fingerprints of 15 batches of dried S. chinensis products were established and similarity evaluation was conducted according to Similarity Evaluation System of TCM Chromatographic Fingerprints (2012 edition). Cluster analysis was used to evaluate the similarity of dried S. chinensis products with different processing methods. At the same time ,HPLC method was adopted to determine the content changes of seven lignans in dried products ,such as schisandrol A , schisandrol B ,schisantherin A ,schisantherin B ,schizandrin A ,schisandrin B and schisandrin C. RESULTS :A total of 7 common peaks were obtained in the fingerprints of 15 batches of dried S. chinensis products. Except that the similarity between the chromatograms of dried samples in the sun and the control fingerprint was relatively low ,the similarities of chromatograms of dried products by other processing methods were greater than 0.900. Cluster analysis showed that 6 samples dried at 50 ℃ after“green removing”processing with microwave and dried at 50 ℃ after“green removing ”processing with blanching were grouped into the first category ;3 samples dried at 50 ℃ after“green removing”processing with steaming were grouped into the second category ;6 samples dried at 50 ℃ and dried in sun were grouped into the third category. The content determination results showed that there was no significant difference in the total content of seven lignans in the samples dried at 50 ℃ and dried in the sun (P>0.05). The total contents of seven lignans in the samples dried at 50 ℃ after“green moving ” processing with microwave ,blanching and steaming were significantly higher than those dried at 50 ℃ and dried in sun (P<0.01). CONCLUSIONS:The quality of S. chinensis samples dried after “green moving ”processing with microwave and blanching is better than those directly dried in sun and dried in oven.

Background::Chemotherapy plus granulocyte colony-stimulating factor (GCSF) regimen is one of the available approaches to mobilize peripheral blood progenitor cells (PBPCs). It causes thrombocytopenia and delays leukapheresis. This study aimed to evaluate the role of recombinant human thrombopoietin (rhTPO) before mobilization chemotherapy in facilitating leukapheresis in patients with lymphoma.Methods::In this randomized open-label phase 2 trial, patients were randomly assigned in a 1:2 ratio to receive mobilization with rhTPO plus GCSF in combination with chemotherapy (the rhTPO plus GCSF arm) or GCSF alone in combination with chemotherapy (the GCSF alone arm). The recovery of neutrophils and platelets and the amount of platelet transfusion were monitored.Results::Thirty patients were enrolled in this study between March 2016 and August 2018. Patients in the rhTPO plus GCSF arm (n = 10) had similar platelet nadir after mobilization chemotherapy ( P=0.878) and similar amount of platelet transfusion (median 0 vs. 1 unit, P=0.735) when compared with the GCSF alone arm (n = 20). On the day of leukapheresis, the median platelet count was 86 × 10 9/L (range 18-219) among patients who received rhTPO and 73 × 10 9/L (range 42-197) among those who received GCSF alone ( P=0.982). After the use of rhTPO, the incidence of platelet count <75 × 10 9/L on the day of leukapheresis did not decrease significantly (30.0% vs. 50.0%, P=0.297). Platelet recovery after PBPC transfusion was more rapid in the rhTPO plus GCSF arm (median 8.0 days [95% confidence interval 2.9-13.1] to platelets ≥50 × 10 9/L vs. 11.0 days [95% confidence interval 8.6-13.4], P=0.011). The estimated total cost of the mobilization and reconstitution phases per patient was similar between the two treatmtent groups ( P=0.362 and P=0.067, respectively). Conclusions::Our findings indicate that there was no significant clinical benefit of rhTPO use in facilitating mobilization of progenitor cells, but it may promote platelet recovery in the reconstitution phase after high-dose therapy.Trial registration::This trial has been registered in Clinicaltrials.gov as NCT03014102.
