Objective To investigate the effects of hedysarum polybotys saccharide (HPS) on lipid metabolism and the expression of stearoyl-CoA desaturase-1(SCD-1) gene in rats with non-alcoholic fatty liver disease (NAFLD). To discuss the interfering effects of HPS on NAFLD. Methods The SD rats were randomly divided into the blank control group and the experiment group. Rats in the experiment group were fed with lipid rich food for 8 weeks to establish model and were randomly divided into model group, drug positive group and HPS group. After 8 weeks of drug intervention, the level of ALT, AST, TC, TG, HDL-c and LDL-c were measured with automatic chemistry analyzer, and expression of SCD-1 gene was measured by semi-quantitative polymerase chain reaction.Results Compared with blank control group, serum ALT, AST and TC, TG, LDL-c of model group were higher (P<0.05,P<0.01), the level of HDL-c of model group and the expression of SCD-1 gene were lower (P<0.01). Compared with model group, HPS was useful to decrease serum ALT, AST, LDL-c, TC and TG (P<0.05,P<0.01), and increase the level of HDL-c (P<0.01) and the expression of SCD-1 gene (P<0.01).ConclusionHPS had a positive effect on regulating lipid metabolic disturbance of NAFLD rats and promoting the expression of regulatory gene SCD-1.

Objective To elucidate the function and regulatory mechanism of LyGDI involved delayed cell death in the human K562 cells and HL-60 cells induced by 60Co γ-rays. Methods Erythrosine B cells staining was used to count the apoptosis rate. PI staining and flow cytometry were applied to check the cell cycle. The expression of LYGDI and Rac1 was resolved by Western blot by using monoclonal antibody of LyGDI and Racl. The distribution of Racl protein in cells was observed with immunofluorescence by using the confocal microscope. Results The K562 cells showed G2/M phase arrest and the percent age was 71.3%. The apoptosis rate was very low at early post-irradiation stage in the K562 cells. The apoptosis rate was 14% in the K562 cells at 24 h post-irradiation with 8 Gy of γ-rays, and delayed cell apoptosis was present. LyGDI was cleaved in the K562 cells irradiated by 4 Gy 60 Co γ-rays after 24 hours post-irradiation. The expression of Racl protein was not altered at all, but the distribution was changed in the irradiated cells while the Racl protein moved to cell membrane and a little in cell nucleus. The Racl was activated with the losing the binding affinity with the LyGDI. Conclusion LyGDI could promote the delayed cell apoptosis, which is through the activation of the Rac1.

Objective To study the risk factor and prognosis of concurrent depression in elderly patients with acute myocardial infarction (AMI) treated with percutaneous coronary intervention (PCI). Methods Two hundred and ninety-five AMI patients who received PCI and whose clinical data were complete were selected. Depression was determined by a self-rating scale (SDS), and was confirmed when SDS standard score≥53 scores. The patients were divided into 2 groups according to the ages:senium (age ≥ 60 years, 144 cases) group and younger group (age<60 years, 151 cases). Multiple Logistic regression analysis was used to analyze the related factors of depression. The patients were followed up for 1 year, and the rehospitalization rate, incidence of major adverse cardiovascular events (MACE) and left ventricular ejection fraction (LVEF) at 12 months were compared. Results The incidence of depression in senium group was significantly higher than that in younger group: 41.7%(60/144) vs. 21.2%(32/151), and there was statistical difference (P<0.05). Female gender, hypertension and type 2 diabetes mellitus were the independent risk factor for depression in patients with AMI after PCI (P<0.05). In senium group, the rehospitalization rate and incidence of MACE in patients with depression were significantly higher than those in patients without depression: 18.3% (11/60) vs. 6.0% (5/84) and 15.0% (9/60) vs. 4.8%(4/84), the LVEF was significantly lower than that in patients without depression:(41.50 ± 2.25)%vs. (49.76 ± 2.93)%, and there were statistical differences (P<0.05). The LVEF in patients with depression of senium group was significantly lower than that in patients with depression of younger group:(41.50 ± 2.25)%vs. (51.50 ± 2.32)%, and there was statistical difference (P<0.05). Conclusions The elderly AMI patients treated with PCI have higher rates of depression. Female gender, hypertension and type 2 diabetes mellitus are the important risk factor for depression after PCI. Depression has a significant effect on the prognosis of AMI patients, especially on LVEF in elderly patients.

Objective To investigate the efficacy observation of transcranial direct current stimulation (tDCS)for improving the attention in patients with infarction in basal ganglia area. Methods Sixty consecutive patients with basal ganglia infarction admitted to the Department of Rehabilitation Medicine,the First Affiliated Hospital of Nanchang University from May 2015 to May 2016 were enrolled. They were randomly divided into either a control group or a test group according to the random number table (n = 30 in each group). The patients in both groups received routine rehabilitation training,and those in the test group received tDCS therapy synchronously,and the control group received the sham tDCS stimulation. The evaluations and analyses were conducted with the Montreal cognitive assessment (MoCA),d2 test of attention,and event-related potential-P300 (ERP-P300),respectively in all patients before intervention and 4 weeks after intervention,and they were compared between the groups. Results There was no significant difference before intervention between the two groups (all P > 0. 05). Compared with before intervention,the ERP-P300 latencies were reduced,the amplitudes were increased after intervention in the patients of the test group and the control group (all P < 0. 05). The MoCA total scores (the test group:22. 7 ± 2. 7 vs. 15. 5 ±
2. 4;the control group:17. 2 ±2. 5 vs. 15. 6 ±2. 3),attention dimension scores (the test group:4. 6 ± 1. 2 vs. 2. 4 ± 1. 6;the control group:3. 6 ± 1. 5 vs. 2. 5 ± 1. 5),and the total completion of d2 attention test task, total scores,and concentration degree scores (the test group:295 ± 31 vs. 250 ± 45,279 ± 38 vs. 223 ± 52, 97 ± 22 vs. 75 ± 25;the control group:276 ± 33 vs. 247 ± 45,257 ± 39 vs. 211 ± 56,84 ± 23 vs. 71 ± 24) were all increased (all P < 0. 05),and all the indexes of the test group were better than those of the control group (all P < 0. 05). Conclusion tDCS contributes to the improvement of the attention in patients with infarction in the internal capsule-basal ganglia region.
