Objective To study the relationship between acute myocardial infarction with the distribution of ABO blood type antigen in patients with diabetes.Methods 2 052 patients with diabetes were selected.All patients had blood type records.The patients were divided into A blood type group(n=625),B blood type group(n=548),AB blood type group(n=204),O blood type group(n=675).Records were analyzed for the incidence of acute myocardial infarction.Results (1)The incidence rate of acute myocardial infarction in the A blood type group was 9.44%,which in the B blood type group was 8.03%,whith in the AB blood type group was 6.86%,which in the O blood type group was 5.19%,there was significant difference among the four groups(χ2=9.02,P<0.05).(2)For patients with diabetes,the incidence rate of acute myocardial infarction in the A blood type group was 9.44%,which was significantly higher than 6.52% in the non-A blood type group,the difference was statistically significant(χ2=5.41,P<0.05).(3)For patients with diabetes,the incidence rate of acute myocardial infarction in the non-O blood type group was 8.50%,which was significantly higher than 5.19% in the O blood type group,the difference was statistically significant(χ2=7.24,P<0.05).Conclusion There is a correlation between acute myocardial infarction with ABO blood type in patients with diabetes.For patients with diabetes,the patients with A blood type develop acute myocardial infarction more often than patients with non-A blood type,patients with blood type non-O develop acute myocardial infarction more often than patients with blood type O.

Objective To investigate the prevalence and severity degree of post traumatic stress disorder(PTSD), anxiety and depression, and to explore the different mental profile in different groups involved with an earthquake. Methods 26 days after 8.0 grade earthquake in Wenchuan, psychological rescue team of State Administration of Traditional Chinese Medicine went to some communities in Deyang and Mianzhu area of Sichuan province. In this period, a total of 119 survivors, including students(42), teacher(40) and masses(37), were investigated through impact of event scale (IES), self-rating anxiety scale (SAS) and self-rating depression scale(SDS). Results①The detection rate of score over 19 in IES in 3 groups (students, teacher and masses) were 69％, 80％ and 91.9％, respectively. There was significant difference among these 3 groups (F=5.611, P=0.005<0.01) in respect of severity degree of PTSD. ②The values of severity degree of anxiety in 3 groups were significant higher than normal value (P<0.001, all). There was also significant difference among these 3 groups (F=3.376, P=0.038<0.05) in respect of severity degree of anxiety, with the masses group being significant higher than student and teacher group (P=0.029, P=0.022, respectively). ③The values of severity degree of depression in these 3 groups were significant higher than normal value (P<0.05, all). But there was no significant difference (F= 0.670, P=0.514) among these 3 groups. ConclusionThe results suggested the importance to assess PTSD, anxiety and depression in post-disaster area, especially PTSD and anxiety evaluations in the masses group.

Objective To investigate the K562 cells biological function and related molecular changes in PTEN-PI3K/AKT signaling pathway of leukemia K562 cells by inhibiting the miRNA-21 expression to explore its pathogenesis of leukemia.Methods The chemical synthetic miRNA-21 inhibitor was transfered into K562 cells by electrotransfection.RT-PCR was used to detect the miRNA-21 expression changes.Cell proliferation and apoptosis were determined by using MTT and flow cytometry.Western-blot were used to detect the protein expression changes of PTEN,PI3K and p-AKT respectively.Results The relative expression of miRNA-21 in experimental group was (8.070±5.138)％ at 24 hours,which was lower than control groups (P＜0.05).The apoptotic rate of (13.370±0.250)％ at 24 hours in experimental group was obviously higher than control groups.The cellular proliferation were significantly different at 24 hours.The proliferation inhibition rate was (8.1±0.9)％ at 24 hours,which was up to (43.1±2.1)％ at 60 hours,but the control groups showed no difference.K562 cell proliferation significantly decreased,while cell apoptosis markedly increased by inhibiting miRNA-21 expression (P＜0.01).Western-blot analysis revealed up-regulation of PTEN and down-regulation of PI3K and p-AKT protein expressions after successfully suppressed miRNA-21 expression (P＜0.01).Conclusion Inhibiting miRNA-21 expression in K562 cell could suppress the PI3K/AKT pathway by up-regulation of PTEN expression and promote cell antiproliferative and pro-apoptosis effects.

Objective:To observe any effect of transcranial direct current stimulation (tDCS) on the cognition of stroke survivors and the integrity of their white matter fibers.Methods:Thirty persons with post-stroke cognitive impairment (PSCI) were randomly divided into an experimental group ( n=15) and a control group ( n=15). In addition to basic drug therapy and routine cognition training, the experimental group received 20 minutes of tDCS daily, 5 days per week for 3 weeks, while the control group received sham tDCS stimulation. Before and after the treatment, both groups′ cognitive functioning was evaluated using the mini-mental state examination (MMSE) and the Montreal cognitive assessment scale (MoCA). Their ability in the activities of daily living (ADL) was quantified using the modified Barthel index (MBI). Diffusion tensor imaging (DTI) was employed to observe any changes in the integrity of their white matter fibers. Results:The average MMSE, MOCA and MBI scores of both groups had improved significantly after the treatment, but the improvement in the experimental group was significantly greater than among the controls. The average fractional anisotroposy value of the affected inferior fronto-occipital fasciculus in both groups was positively correlated with the group′s average MMSE score and MoCA score.Conclusion:tDCS can effectively improve the cognition and functioning in the activities of daily living of stroke survivors. Its mechanism may be related to improving the integrity of the white matter fibers involved.

Objective To observe the value of radiomics models and nomogram model based on two-dimensional ultrasound and automated breast volume scanning(ABVS)for predicting molecular types of breast cancer.Methods Data of 326 female patients of single breast cancer confirmed by pathology were analyzed retrospectively.The patients were randomly divided into training set(n=260)or validation set(n=66)at the ratio of 8∶2,and further divided into Luminal subgroup and non-Luminal subgroup.Radiomics features were extracted based on two-dimensional ultrasound of breast and ABVS imaging,then model2DUS,modelABVS and modelcombined radiomics were constructed,respectively.Univariate analysis and multivariate logistic regression analysis were used to screen independent factors for predicting molecular types of breast cancer,and nomogram model(modelnomogram)was constructed combined with independent factors and radiomics Radscores.The receiver operating characteristic(ROC)curve was used to evaluate the efficacy of each model for molecular type of breast cancer.Results The maximum diameter of tumor(OR=1.029)and the retraction phenomenon(OR=0.408)were both independent predictive factors for molecular type of breast cancer(both P＜0.05).The area under the curve(AUC)of model2DUS,modelABVS.modelcombined radiomics and modelnomogram for predicting molecular type of breast cancer in validation set was 0.67,0.75,0.84 and 0.83,respectively.No significant difference of AUC of modelcombined radiomics and modelnomogram was found(P＞0.05),which were both higher than AUC of model2DUs and modelABVS(all P＜0.05).Conclusion Combined radiomics model and nomogram model based on two-dimensional ultrasound and ABVS could effectively predict molecular type of breast cancer.
