To explore the depression in type 2 diabetic patients treated with insulin and compared to those treated with oral anti-diabetic drugs.283 type 2 diabetics were seclected randomly from outpatient and inpatient departments of endocrionology in Jiangsu Province Hospital of Traditional Chinese Medicine,with the self-designed questionnaire and Zung self-rating depression scale to conduct the survey.Comparisons between the two groups were carried out with t-test or x2 test for quantitative and qualitative data,respectively.Logistic regression were used for the analysis of the relationship between the therapeutic regimen and depression.Overall,43.1％ of the type 2 diabetic subjects showed depressive symptoms in different degrees.Compared to the oral drug group,the insulin group showed a significantly higher prevalence of depressive symptoms (insulin group,53.5％,oral drug group,30.5％;P＜0.01)and higher self-rating depression scale scores (insulin group,51.7 ± 12.4,oral drug group,44.8 ± 10.6;P＜0.01).Moreover,after an adjustment for age,sex,body mass index,diabetic duration,complications,HbA1Cand so on,the insulin group showed a significantly higher frequency of depression (OR=4.218,95％ CI 1.764-13.285,P=0.004),compared to the oral drug group.The data showed that insulin treatment is an independent risk factor to the presence of depressive symptoms in type 2 diabetics,and it is necessary to pay more attention to their psychological support.

ABSTRACT:Objective To observe the effect of curcumin on RAW264.7 macrophages induced with LPS and IFNγ(M1)and the mechanisms involved.Methods Curcumin of different concentrations (6.25 μmol/L,12.5μmol/L and 25 μmol/L)was used to treat RAW264.7 macrophages induced with LPS and IFNγ(M1)for 12 h,and RAW264.7 macrophages induced with LPS and IFNγ(M1)were incubated with 20μmol/L GW9662 and 25 μmol/L curcumin for 12 h.Using Real-time PCR,ELISA and Western blotting analysis,we examined the expressions of IL-1β,IL-6,PPARγand phenotype markers M2 (KLF4,FIZZ1,and MGL1 )and the expressions of KLF4 and FIZZ1 when PPARγwas inhibited.Results Curcumin of different concentrations all could inhibit the expressions of IL-1βand IL-6 in RAW264.7 macrophages induced with LPS and IFNγ(M1).Curcumin of different concentra-tions could upregulate the expression of M2 markers (KLF4,FIZZ1 and MGL1)and PPARγin RAW264.7 macro-phages induced with LPS and IFNγ(M1).When M1 macrophages were incubated with curcumin and GW9662,the expression of the M2 phenotype markers was reduced.Conclusion Curcumin polarized the M1 phenotype macro-phages derived from RAW264.7 macrophages to become M2 phenotype through activating PPARγ.

Objective To evaluate the growth inhibition and apoptosis of human monocytic leukemia THP-1 cell line by using 5,8-dimethyl-2-β-hydroxyisovalerylshikonin (SK36) and explore its preliminary mechanism. Methods CCK colorimetric assay and cell counting was used to examine the growth inhibition of shikonin on THP-1 cells. The apoptosis of THP-1 cells was detected by Annexin V/PI double labeling. The activation of Caspase-3 apoptosis pathway was determined by FCM. The apoptosis and the necrosis of THP-1 cells were detected by the laser scanning confocal microscopy. Results When the THP-1 cells were treated with SK36 at 1.02 μg/ml for 24 h and 48 h, the growth inhibition was dose-dependent. The cell apoptotic rate of THP-1 cells treated with 1.02 μg/ml evaluated by FCM with Annexin V/PI double labeling staining were (40.61 ±2.13) % and (67.40±9.15) % at 24 h and 48 h after treatment, respectively, which were significantly higher than that of the control group [(16.97±0.61) %] ([ = 18.444, t = 9.528, P <0.01). SK36 could induce THP-1 cells apoptosis involving the activation of Caspase-3 (F= 323.61, P<0.01). Conclusion SK36 can induce human THP-1 cells to undergo apoptosis, and its primary mechanism was to activate the Caspase-3.

Objective Large-conductance culcium-activated potassium (BKCa) channel modulates vascular smooth muscle tone. In the present study, we tested the hypothesis that salt, one of the factors which significantly influence bleed pressure (BP), can regulate BKCa activity and then elevate blood pressure. Methods Male Spragne-Dawley rats aged 6 weeks were randomized into high salt diet group (HS) and control group, fed with high salt diet (containing 5% NaCi) and standard rat chow (containing 0.4% NaCl) respectively for 16 weeks. Tail systolic blood pressure (SBP), body weight (BW) and 24-hour urinary output were tested every 4 weeks. Content of urinary Na+ was detected using flame spectrophotometrical method. At the end of 16 weeks, all the rats were killed, the mesenteric arteries were obtained, and single mesenteric smooth muscle cells were isolated at once. The resting membrane potential (Em), the total potassium currents and the currents after perfusion with TEA solution of the cells were all recorded by whole cell patch clamp. The transcriptions of BKCa channel α and β1 sobunits in mesenteric arterial vascular smooth muscle cells (VSMC) of each group were calculated by real-time RT-PCR. Results There was no difference in SBP and BW at each stage between control group and HS group; the urinary Na+ level in HS animals was elevated significantly after 4 weeks.The negative values of Em in HS group VSMCs were reduced compared with these in the control group. Transcriptions of β1 subanit of BKCa channels were decreased in HS group, but α subunit transcriptions did not differ between the two groups. Whole cell potassium currents did not differ hetween HS and control groups, but BKCa currents of HS group VSMCs were lower than these of control group ones. Conclusion Even without elevating SBP, salt-loading can still modulate the expression and activity of BKCa channel in the mesenteric arterial VSMC and elevate vascular tone.

Objective To compare coronary artery abnormality between patients with silent myocardial ischemia (SMI)and pa-tients with symptomatic myocardial ischemia using coronary artery CT angiography.Methods Forty-three patients with SMI and 45 patients with symptomatic myocardial ischemia were collected and underwent coronary CT angiography using 128-slices spiral CT scanner,respectively.Results Stenosis of coronary artery detected in 23 patients with SMI was (23/43,53.49%),and stenosis in 21 patients with symptomatic myocardial ischemia was (21/45,46.67%).The difference of incidence had no statistical significance, but the degree of stenosis and the number of stenosis vessel had statistical significance(P <0.05).The number of atherosclerotic plaque of coronary artery detected in patients with symptomatic myocardial ischemia was significantly more than that in patients with SMI(P <0.05).Conclusion There are no significant difference in the incidence of coronary stenosis between the patients with SMI and patients with symptomatic myocardial ischemia.However,the degree of stenosis and incidence of atherosclerotic plaque are sig-nificant different.
