RESUMO
BACKGROUND: Autism spectrum disorder (ASD) is a highly heterogeneous neurodevelopmental disorder with complex pathogenesis. Currently, the pathogenesis of ASD is not fully understood. Moreover, current treatments do not effectively alleviate the primary symptoms of ASD social disorder (SCDA). Jiawei Yinhuo Tang (JWYHT) is an improved version of the classic prescription Yinhuo Tang. Although this medication has been shown to improve social behavior in ASD patients, the mechanism by which it works remains unknown. METHODS: In this study, network pharmacology bioinformatics analysis was used to identify the key targets, biological functions, and signal pathways of JWYHT in SCDA. Then, molecular docking and molecular dynamic simulation were used to validate the activity and stability of the active ingredient and the target protein during the binding process. RESULTS: The analysis identified 157 key targets and 9 core targets of JWYHT (including proto-oncogene (FOS), caspase 3 (CASP3), mitogen-activated protein kinase-3 (MAPK3), interleukin-6 (IL6), mitogen-activated protein kinase-1 (MAPK1), tumor necrosis factor (TNF), mitogen-activated protein kinase-8 (MAPK8), AKT serine/threonine kinase 1 (AKT1), and 5-hydroxytryptamine receptor 1B (5HT1B)) in SCDA. In addition, the Kyoto Encyclopedia of Gene and Genome results, as well as the staggering network analyses, revealed 20 biological processes and 20 signal pathways targeted by JWYHT in SCDA. Finally, molecular docking analysis was used to determine the binding activity of the main active components of JWYHT to the key targets. The binding activity and stability of methyl arachidonate and MAPK8 were demonstrated using molecular dynamics simulation. CONCLUSION: This study demonstrates that JWYHT regulates neuronal development, synaptic transmission, intestinal and cerebral inflammatory response, and other processes in SCDA.
RESUMO
The mass start event is the longest cross-country skiing event added first time in the Pyeongchang Winter Olympics held in 2018. This study aimed to highlight tactics characteristics of the event by making a statistical analysis of the points and competition results of athletes who participated in this event in the Pyeongchang Winter Olympics. For this purpose, the ranks, points, lap time, and final results of 16 male and 16 female athletes were taken as research objects in the final mass-start event of speed skating of the 2018 Pyeongchang Winter Olympics. The speed and speed coefficient of this segment were calculated by Pearson correlation analysis applying the Origin 9.4 software for nonlinear curve fitting. The results showed that athletes adopted different speed pacing strategies in each race. The analysis was based on a comparison of points and speed rhythms of different rounds. This enabled to identify and optimize tactics that might improve the probability of winning the event. This study contributes significantly with both theoretical and practical implications. The study findings specify such optimization tactics to provide a theoretical basis for sports practices as well as giving practical insights important to practitioners and sports officials. The study recommends that physical fitness should be strengthened to ensure athletes' speed endurance in speed-skating; teammates should work together tactically to get rid of the impact caused by physical exertion, and a training platform should be built to train athletes.(AU)

Objective To observe the efficacy and toxicity of thermotherapy plus chemotherapy in treatment of retroperitoneal lymph node metastasis after radical gastrectomy and sequential radiochemotherapy. Methods Sixty patients with retroperitoneal lymph node metastasis after radical gastrectomy and sequential radiochemotherapy were randomly divided into of microwave hyperthermia combined with chemotherapy group (experimental group, 30 cases) and chemotherapy group (control group, 30 cases) by using random number table method. The control group: oxaliplatin 130 mg/m2, intravenous drip (2 h), d1; S-1: 80 mg·m-2·d-1, P.O 2 times/d (after breakfast and after dinner), d1-14. 3 weeks was 1 cycle, a total of 4 cycles. The experimental group: chemotherapy on the basis of control group combined with microwave hyperthermia, d1, 8. the efficacy and toxicity of two groups were evaluated. Results The efficacy rate of the experimental group was higher than that of the control group, and the difference was statistically significant [66.7 % (20/30) vs. 33.3 %(10/30), P0.05]. There was no significant difference in bone marrow suppression of two groups [33.3%(10/30) vs. 30.0 % (9/30), P> 0.05]. Conclusion Microwave thermotherapy plus chemotherapy has a good efficacy for retroperitoneal lymph node metastasis after radical gastrectomy and sequential radiochemotherapy, and the patients can well tolerated, it is worthy of clinical promotion.
RESUMO
Objective To explore the mechanism by which liraglutide modulated the differentiation of monocyte subsets in high glucose (HG) conditions.Methods Primary mouse splenocyte suspensions were cultured in HG conditions induced by IFN-γ in the presence or absence of liraglutide.The cells were harvested,co-incubated with antibodies,and analyzed on a BD FACS Calibur.Mononuclear cells (MNCs) were gated according to lower granularity and larger size by SSC and FSC.Monocytes (MCs) were defined as CD11b+MNC and divided into three subsets based on Ly6C expression:Ly6Clow,Ly6Cmid,and Ly6Chi.ROS production in Ly6C+ and Ly6C-MCs was detected by 2',7'-dichlorofluorescein-diacetate (DCFH-DA) staining and ROS-containing MCs were identified as DCF+ cells in both Ly6C+ and Ly6C-MCs.Results HG (15 mmol/L,25 mmol/L,35 mmol/L) dose-dependently increased Ly6Chi and Ly6Cmid MC differentiation and also enhanced the production of ROS in Ly6C+MCs.Liraglutide (100 U,200 U) dose-dependently inhibited HG-induced Ly6Chi and Ly6Cmid MC differentiation and also promoted the differentiation of Ly6Clow MCs.Moreover,liraglutide significantly inhibited HG-induced ROS production in Ly6C+ MCs.Conclusion Liraglutide treatment significantly inhibited inflammatory MC diferentiation induced by HG and also reduced ROS production in inflammatory MCs.
RESUMO
Objective To investigate the possible mechanism of hyperhomocysteinemia (HHcy) in renal dysfunction in patients with chronic stable coronary artery disease (SCAD).Methods We consequentially enrolled patients diagnosed as having SCAD and,according to homocysteine (Hcy) levels,divided them into the HHcy group (Hcy≥15 μmol/L,n =53) and control group (Hcy＜15 μmol/L,n =47).We further tested the relationship among plasma Hcy level,renal function,and serum levels of interleukin (IL)-6 and adiponectin (APN).Results IL-6 was significantly higher in the HHcy group than in the control group (P ＜ 0.05).However,APN level was obviously lower in the HHcy group than in the control group (P ＜ 0.05).Correlation analysis revealed that Hcy level positively correlated with creatinine (r =0.379,P ＜ 0.001),uric acid (r =0.238,P =0.019),cystatin C (r =0513,P ＜ 0.001),and IL-6 levels (r =0.561,P ＜ 0.001) but negatively correlated with estimated glomerular filtration rate (eGFR;r =-0.288,P =0.023) and APN level (r =-0.428,P ＜ 0.001).IL-6 level showed positive correlations with creatinine (r =0.406,P =0.002),uric acid (r =0.359,P =0.007),and cystatin C levels (r =0.387,P =0.007) but a negative correlation with eGFR (r =-0.370,P =0.005).Meanwhile,APN level showed negative correlations with creatinine (r =-0.694,P ＜ 0.001),uric acid (r =-0.420,P ＜0.001),and cystatin C levels (r =-0.553,P ＜ 0.001),but a positive correlation with eGFR (r =0.251,P =0.034).Conclusion Plasma Hcy level may have a predictive value for renal dysfunction in patients with SCAD.Moreover,HHcy probably promoted renal dysfunction by inducing the imbalance of anti-inflammation and pro-inflammation in patients with SCAD.
