Objective:To explore the influence of Shenhong Tongluo Granules in the lipid levels,atherosclerosis plaques and apoptosis in the plaques of atherosclerotic apolipoprotein E (ApoE)-knokout mice,and to clarify the mechanism of Shenhong Tongluo Granules in anti-atherosclerosis.Methods:Forty SPF male mice aged six-week old were randomly divided into normal control group,model group,low dose of traditional chinese medicine (TCM) group and high dose of TCM group (n=10)after fed adaptively for 1 week.The mice in normal control group were fed with normal diet continuously, the mice in other three groups were fed with high fat diet to establish atherosclerosis model,and then the mice in low and high doses of TCM groups were respectively given Shenhong Tongluo Granules (5.06 and 10.12 g·kg-1 · d-1 )by gavage for 6 weeks. The levels of serum total cholesterol (TC),triglycerides (TG),low density lipoprotein cholesterol (LDL-C)and high density lipoprotein cholesterol (HDL-C)of the mice in various groups were measured after the eyeball blood was collected.The aortic arch tissue was separated,and the morphotogy and the areas of atherosclerotic plaques were observed and calculated by HE staining;the apoptosis in plaques of the mice was evaluated by TUNEL method, and the apoptosis index was calculated. The expressions of apoptosis-assoicated gene Bcl-2 and Bax protein were measured by immunohistochemical staining.Results:The serum level of TG in low dose of TCM group was lower than that in model group (P <0.05);the serum levels of HDL-C in low and high doses of TCM groups were lower than that in model group (P <0.05 or P <0.01);the serum levels of TG and HDL-C in high dose of TCM group was higher than that in low dose of TCM group (P <0.05).The areas of atherosclerotic plaques of the mice in low and high doses of TCM groups were significantly smaller than that in model group (P <0.01).The apoptosis index of mice in low and high doses of TCM groups were significantly lower than that in model group (P <0.01);the expression levels of Bcl-2 protein in atherosclerosis plaques of the mice in low and high doses of TCM groups were lower than that in model group,while the expression levels of Bax were significantly higher than that in model group (P <0.05 or P <0.01).Conclusion:Shenhong Tongluo Granules could effectively reduce the serum lipid level of ApoE-/-mice,meanwhile it could inhibit apoptosis by regulating the expressions of Bcl-2 and Bax protein,and then inhibit the progression of atherosclerotic plaques.

Objective:To explore the influence of rosuvastatin in the lipid levels, atherosclerosis plaque and apoptosis in the plaque of atherosclerotic apolipoprotein E (ApoE)-knockout mouse models, and to clarify the mechanism of rosuvastatin in inhibiting atheromatous plaque and apoptosis in the plaque.Methods:Thirty healthy six-week old male mice were randomly divided into high fat diet group (n=10),rosuvastatin group (n=10)and general diet control group (n=10).The mice in first two groups were fed with high fat diet,and the mice in general diet control group were fed with general diet;4 weeks later the mice in three groups were respectively given 0.9% NaCl solution,rosuvastatin (10 mg·kg·d-1 )and 0.9% NaCl solution by gavage for 8 weeks.And then ELISA was used to detect the serum lipid levels,the area of atherosclerotic plaque was measured by HE staining, and the apoptosis in plaques was detected by TUNEL method;the expression of apoptosis-assoicated gene Bax protein was measured by immunohistochemical staining.Results:Compared with high fat diet group,the levels of total cholesterol (TC)and low density lipoprotein cholesterol (LDL-C)of the mice in rosuvastatin group were significantly decreased (P<0.05 or P<0.01),and the 1evel of high density lipoprotein cholesterol (HDL-C)was significantly increased (P<0.01).The aortic atherosclerotic plaque of the mice in high fat diet group was massive with a great quantity of foam cells, cholesterol crystal, necrotic cells and inflammatory cells in the plaque;the aortic atherosclerotic plaque of the mice in rosuvastatin group was smaller with less foam cells,necrotic cells and inflammatory cells;the aortic atherosclerotic plaque area of the mice in rosuvastatin group was significantly smaller than that in high fat diet group (P<0.01);the apoptotic index in the aortic atherosclerotic plaque of the mice in rosuvastatin group was significantly lower than that in high fat diet group (P<0.01).Compared with high fat diet group,the expression of Bax protein in rosuvastatin group was significantly decreased.Conclusion:Rosuvastatin may inhibit the progression of atherosclerotic plaque and the apoptosis in plaques through mitochondrial pathway.

Objective To explore the predictive effect of depression and impulsivity on suicidal ideation in violent criminals.methods 423 violent criminals were assessed by Self-rating Idea of Suicide Scale(SIOSS),Patient Health Questionnaire (PHQ-9) and Barratt Impulsiveness Scale(BIS-11).Result sPeople with suicidal ideation accounted for 17.04% of the total number of violent criminals.The scores of the group with suicidal ideation (respectively (4.95±4.82),(56.79±8.68),(12.95±2.29),(19.03±3.91),(28.81±4.95)) were higher than those without suicidal ideation group (respectively (4.95±4.82),(56.79±8.68),(12.95±2.29),(19.03±3.91),(28.81±4.95)) in depression and every dimension of impulsivity(attentional impulsivity,motor impulsivity and non-planning impulsivity) (t=9.49,t=4.61,t=4.04,t=3.88,t=3.08) (all P<0.01).Positive correlation was observed between suicidal ideation,depression and impulsivity(r=0.156-0.628,P<0.01),while sleeping factor was not associated with non-planning impulsivity.According to the multi-factoral regression module,depression and nonplanning impulsivity scores had positive prediction on suicidal ideation(R2=0.419,SIOSS=-2.471+ 0.192× depression+ 0.149× nonplanning impulsivity).Conclusion There is a close relationship in suicidal ideation,depression and impulsivity,meanwhile depression and nonplanning impulsivity can predict the suicidal ideation.

Objective To investigate the impulsive traits and their influencing factors in different types of male inmates. Methods A total of 1 206 male inmates in Jiangsu province were assessed by a self-designed questionnaire of detailed criminal records,demographic data,history of substance use and Barratt Impulsiveness Scale (BIS-11).Results ①Significant differences were found between the distribution of age (F＝30.092),educational level(χ2＝84.479),marital status(χ2＝54.386),household registration(χ2＝34.959),smoking history (χ2＝19.047)and drug use history( χ2＝563.144) of male inmates( all P＜0.01).②Difference of impulsivity was found between different types of male inmates,and scores of the impulsivity of the property inmates (total impulsivity (55.92±8.39),attentional impulsiveness (12.70±2.35),motor im-pulsiveness (18.50± 3.88),non-planning impulsivity ( 24.72 ± 4.91)) were significantly lower than other crime types (P＜0.05).③Drug use history had a positive predictive effect on impulsivity of male violent in-mates (B＝4.317,P＜0.01),and educational level(B＝－3.280,P＜0.001),age(B＝－0.094,P＜0.05)and drug use history ( B＝ 3.491, P＜ 0.05 ) had a predictive effect on impulsivity of male property inmates. Conclusion The impulsivity of male property inmates is significantly lower than others and the influence factors of impulsivity among male inmates are age,educational level and drug use history.
