ObjectiveTo investigate the effect of β-adrenergic receptor(β2AR) stimulation on vascular smooth muscle cell apoptosis in physiological state and receptor overexpression model.Methodsβ2AR overexpression model was established by transgenic techniques. Hoechst 33342 staining as well as flow cytometer(FCM) detected were chosen to measure the incidence of vascular smooth muscle cell apoptosis.ResultsVascular smooth muscle cell exhibited significantly fewer viable cell rate when stimulated with β2AR agonist isoproteronol for 48 hours compared with control (P<0.01),while no difference at the time point of 24 hours. Much fewer viable rate detected by FCM and high apoptotic rate by Hoechst staining were observed when VSMCs overexpressing β2AR were stimulated with isoproteronol for 24 hours (P<0.01).ConclusionStimulation of physiological and overexpressing β2AR could induce apoptosis of vascular smooth muscle cell.

Objective To detect and investigate the expression and the effect of Prohibitin (PHB) in rats with renal interstitial fibrosis (RIF) induced by unilateral ureteral obstruction (UUO) .Methods Forty-eight Wistar male rats (6-weeks-old) were randomly assigned into 2 groups,sham-operated and model group.The model group rats were subjected to left ureteral ligation after anesthesia and the sham-operated group rats were subjected to sham operation.Six rats were killed 7,14,21,28 days after operation respectively.The renal tissues were collected.The index of RIF was calculated.The expressions of mRNA and protein of PHB were assayed by real time polymerase chain reaction and immunohistochemistry. Results Compared with sham-operation group,at each time point,the model group had significantly increased index of RIF (P < 0.01) and the obstruction for a longer period showed the higher index; the model group had significantly decreased expression of mRNA and protein of PHB (P < 0.01) and the obstruction for a longer period showed the lower expression; the model group had significantly increased expression of mRNA and protein of TGF-β1 (P < 0.01) and the obstruction for a longer period showed the higher expression.Correlation analysis showed that the index of RIF was negatively correlated with FHB (γ = -0.825) and positively correlated with TGF-β1 (γ = 0.995),while there was a positive correlation between PHB and TGF-β1 (γ = -0.786).Conclusions The lower expression of PHB in renal tissue of UUO rats might suggest that it play an important role in RIF.

Objective To evaluate the effect of retention time of urokinase on hematoma dissipation in the treatment of severe ventricular hemorrhage by lateral ventricle drainage. Methods The clinical data of 62 patients with severe ventricular hemorrhage and having received bilateral ventriculostomy were retrospectively analyzed. These patients was divided into 3 groups according to the retention time of urokinase: A group (20 patients, retention time 1 h), B group (22 patients, retention time 2 h) , and C group (20 patients , retention time 3 h).The number of patients with complete hematoma dissipation at different time in each group were compared. Results At 5-6 d, 7-9 d and 10-12 d after operation, the number of hematoma dissipation in A group was 2, 5, 13 cases, in B group was 5, 13, 4 cases, and in C g group was 3, 13, 4 cases. The number of hematoma dissipation patients in three groups had significant difference (P=0.008), the number of hematoma dissipation patients between A group and B group, and between A group and C group had significant differences (P=0.005, 0.012), but there was no significant difference between B group and C group (P=0.621). The complication rate in three groups had no significant difference (χ2=2.540, P=0.281). Conclusions The 2 h retention time of urokinase is more suitable for the patients with severe ventricular hemorrhage who underwent external drainage.

Objective To investigate the normal range of the femoral neck α-angle in normal Chinese adults and classify the morphology of the anterior femoral head-neck junction on CT-based images. Methods Six hundred and fifty-two adult patients (Bilateral: 459 patients, unilateral:193 patients) with the total of 1111 hips (552 left; 559 right, and 654 male; 457 female) without known diseases affecting the proximal femur or symptoms of femoroacetabular impingement (FAI) underwent 64-slice CT scanning for medical purpose with the hip included in the scan range. The volume CT data was used for further analysis in this study. Oblique sagittal plane images paralleling to the axis of the femoral neck were reconstructed with the volume CT data, the image through the middle of the femoral neck was chosen to measure α-angle with AutoCAD2006 software. The morphology of the anterior femoral head-neck junction was classified. Analysis of variance and t-test were performed with SPSS 15.0. Results The mean value of α-angle of all 1111 hips was 38. 2° ±5.3°. The normal range of α-angle in Chinese adults was 28°to 49°.The mean value of left and right α-angles were 38. 0° ±5. 3°and 38.4° ±5. 3° ,respectively, and there was no statistically significant difference between both sides (t = - 1. 231 ,P > 0. 05 ). Males have greater α-angles than females 39. 2° ±5. 8 vs 36. 8° ±4. 1°, with t = -8. 180, P <0. 01. There was no statistically significant differences of the α-angles of the seven age groups (F = 1. 765, P > 0. 05 ). In all 1111 proximal femora, 168 were classified as concave type, accounting for 15. 1%, with a mean α-angle of 31.2° ±2. 0°,726 were smooth type, accounting for 65.4%, with a mean α-angle of 37.4° ± 2. 4°, and 217 were flat type, accounting for 19.5%, with a mean α-angle of 46. 4° ±3. 8°. The differences of the α-angles of the three groups reached statistical significance ( F = 1636. 107, P < 0. 01 ). Conclusions The morphology of anterior femoral head-neck junction can be classified into three types: concave type (type Ⅰ ), smooth type (type Ⅱ ) and flat type (type Ⅲ ). This classification could directly reflect α-angle, which helps to recognize the variation of the offset of anterior femoral head-neck junction. This study offers basic data for the diagnosis of FAI.
