Objective:To investigate the effect of miRNA-618 (miR-618) on the cell proliferation and apoptosis of acute monocyte leukemia THP-1 cells.Methods:Real-time polymerase chain reaction (PCR) was used to detect the relative expression level of miR-618 in THP-1 cells and monocytes isolated from peripheral blood of the healthy people. Overexpression of miR-618 plasimid vector was constructed and empty vector was treated as the negative control; and then the two vectors were transfected with THP-1 cells; finally, miR-618 overexpression group and negative control group were set. THP-1 cell proliferation and apoptosis of both groups were detected by using CCK-8 method and flow cytometry, respectively. TargetScan was used to predict the target gene of miR-618 and it was verified by using luciferase reporter assay.Western blot was used to detect the protein levels of THP-1 cells in miR-618 overexpression group and negative control group, and predicted miR-618 target gene in peripheral blood monocytes of the healthy people.Results:PCR showed that the expression level of miR-618 was lower in THP-1 cells compared with that in monocytes isolated from peripheral blood of the healthy people ( P < 0.05). CCK-8 assay showed that compared with the negative control group, the proliferation ability of THP-1 cells in miR-618 overexpression group was decreased (the absorbance values at 0, 24, 48 and 72 h after transfection: 0.20±0.03 vs. 0.20±0.03, 0.28±0.02 vs. 0.35±0.03, 0.34±0.03 vs. 0.43±0.04, 0.39±0.02 vs. 0.53±0.05, all P < 0.05), and the late apoptosis rate was increased [(27.1±0.1)% vs. (14.9±0.1)%, t=2.13, P=0.03]. The target gene of miR-618 was ARPP19 predicted by using TargetScan software. Luciferase reporter assay showed that the relative luciferase activity of THP-1 cells in group transfected with wild-type ARPP19 gene plasmid+miR-618 gene plasmid was higher than that in the blank control group and group transfected with wild-type ARPP19 gene plasmid+miR-618 empty vector (0.170±0.003 vs. 0.100±0.004, 0.100±0.001, all P < 0.05). Western blot indicated the expression level of ARPP19 protein in THP-1 cells of miR-618 overexpression group was lower than that of the negative control group, while the expression levels of ARPP19 protein of peripheral blood monocytes of the healthy people in both groups were similar. Conclusion:miR-618 can inhibit the cell proliferation and promote apoptosis of THP-1 cells by inhibiting the expression of of THP-1 cells ARPP19 in acute monocyte leukemia.

OBJECTIVETo investigate the changes of CD4 + CD25 + Foxp3 + regulatory T cells in the peripheral blood mononuclear cells (PBMC) and their association with insulin resistance in different stages of prostate cancer (PCa).
METHODSUsing flow cytometry, we counted the CD4+ CD25 + Foxp3 + regulatory T cells in the PBMCs of 62 PCa patients (5 cases of TNM stage I, 16 cases of stage II, 21 cases of stage III, and 20 cases of stage IV) and 42 normal healthy controls, and calculated their proportion in the CD4+ T-lymphocytes. We determined the levels of fast blood glucose (FBG) and fast insulin (FINS) for the insulin resistance index (HOMA-IR), obtained the serum IGF-1 level by ELISA, and analyzed the relationship of the count and proportion of CD4+ CD25+ Foxp3+ regulatory T cells with insulin resistance by comparison between the PCa patients and normal healthy controls.
RESULTSCompared with the control group, the PCa patients showed significantly increased HOMA-IR (3.68 ± 1.42 vs 6.68 ± 1.66), decreased level of serum IGF-1 ([164.56 ± 30.58] vs [96.39 ± 21.21] ng/ml), and elevated count ([1.99 ± 0.78 ] x 10(7) vs [3.55 ± 0.29] x 10(7)) and proportion ([5.33 ± 0.65] vs [13.88 ± 0.96]%) of CD4 + CD25 + Foxp3 regulatory T cells in the PBMCs. The TNM stage was correlated positively with the count and percentage of CD4 + CD25+ Foxp3 + regulatory T cells and HOMA-IR, but negatively with the level of serum IGF-1. Meanwhile, the count and percentage of CD4 + CD25 + Foxp3 + regulatory T cells were found to have a positive correlation with HOMA-IR (r = 0.722 and 0.689, P < 0.01) but a negative correlation with the level of serum IGF-1 (r = -0.747 and -0.896, P < 0.01).
CONCLUSIONThe count and proportion of CD4+ CD25 + Foxp3 + regulatory T cells in the peripheral blood and insulin resistance increase with the elevated stage of PCa. CD4 + CD25 + Foxp3 + regulatory T cells may be involved in the occurrence and progression of PCa by regulating insulin resistance.

Objective To investigate the variation of the thioredoxin system (Trx),and the role of it in transient out-ward potassium current (Ito) channels in left ventricular myocytes of diabetes mellitus (DM) in rats. Methods Forty-five SD rats were divided into DM group and control group. DM group were treated with streptozotocin (STZ) to induce DM model. The values of left ventricular end diastolic diameter (LVEDD), end-systolic diameter (LVESD), fractional shortening (LVFS), ejection fraction (LVEF) and heart rate (HR), QRS duration and corrected QT (QTc) interval were detected by echocardiogra-phy (UCG) and electrocardiogram (ECG) in two groups. The left ventricular myocardial tissue samples were taken to detect the Trx,glutaredoxin (GRX),thioredoxin reductase (TrxR) and glutathione reductase (GR) by using UV spectrophotometer. The level of free thiol (P-SH) of total cardiac protein was detected by 5, 5′-dithio-bis-2-nitrobenzoic acid method. Ito of the cardiomyocytes was recorded by whole-cell patch-clamp method. After being incubated in vitro with insulin(Ins), treated with TrxR inhibitor-auranofin(AF) and 13-cis-retinoic acid(RA), the changes of Ito of the cardiomyocytes were observed. Results Compared with control group, the values of heart rate (HR), left ventricular minor axis decurtaion rate (LVFS), left ventricular ejection fraction (LVEF) and TrxR were lower in DM group. The values of LVEDD, LVESD, QRS and QTc inter-vals, Trx, Grx and P-SH were higher in DM group than those of control group. Ito density was significantly higher in DM+Ins group than that of DM group, Ins+RA group and Ins+AF group when the stimulation voltage ≥ 0 mV (P < 0.05). Conclusion The impaired Trx system in diabetic rat myocardium was the electrophysiological basis of the reduced ventric-ular function and arrhythmia. And Ins was able to reverse the decreased Ito of cardiomyocytes in DM rats.

Objective To summarize the diagnosis,treatment and prevention of dysuria within 6 months after the suprapubic transvesical prostatectomy. Methods Twenty-four cases were retrospectively reviewed,including the data on the diagnosis, treatment and prognosis. Results Twenty-one of the 24 cases had received surgery. There were 9 cases with bladder neck stricture,9 cases with posterior urethra stricture and 3 cases with of remnant glands. Nine cases received transurethral bladder neck incision, 9 received open surgery ( bladder neck,posterior urethral incision) and 3 received transurethral resection of the prostate (TURP) plus bladder neck incision. The other 3 diagnosed as detrusor weakness were conservatively treated by indwelling catheter and they were improved one months later. None of these patients was readmitted into hospital for dysuria within 6 months after treatment. Conclusion The recurrence of dysuria post prostatectomy mostly ( 75% ) occurred within 6 months after surgery. A majority of these patients need a second surgery. To avoid a second surgery for postoperative dysuria, much attention should be paid to the operating technique and postoperative management.
