objective To assess the effect of aldosterone on the production of matrix metalloproteinase-2 (MMP-2), matrix metalloproteinase-9 (MMP-9)and collagen Ⅳ in culture supematants of podocytes and the possible molecular mechanisms involved in the influence of aldosterone on the synthesis and degradation of extracellular matrix produced by podocytes. Methods Podecytes were treated with aldosterone at the concentration of 10-11, 10-9, 10-7 mol/L respectively. Cultured podocytes were examined at 24, 48 and 72 hours respectively. Spironolactone, a receptor antagonist of aldosterone, was added to observe the blocking effect on aldosterone. An inhibitor of TGF-β1 receptor was used to determine whether the effect of aldosterone on podocytes were mediated through TGF-β1 system. The enzymatic activities of MMP-2 and MMP-9 were assayed by gehtin zymography. Collagen Ⅳ 0.5 chain and TGF-β1 proteins released into culture supematants were assessed by Western blot and ELISA analysis. The adhesion rate of podocytes was monitored by flow cytometry. Results Aldosterone increased the activities of MMP-2 and MMP-9 in a dose- and time-dependent manner (P<0.05). Aldosterone decreased the level of collagen Ⅳ or5 chain protein in culture supernatants (P<0.05). Meanwhile, the expression of TGF-β1 was also increased (P<0.05). Spironolactone completely abolished the above-mentioned changes(P< 0.05). Blockage of TGF-β1 signaling with SB431542 prevented the aldosterone-induced upregulation of MMP-2 and MMP-9 as well as the downregulation of the collagen Ⅳ α5 chain protein and the adhesion rate of podocytes (P<0.05). Conclusions Aldosterone increases the activities of MMP-2 and MMP-9 but decreases the expression of collagen Ⅳ α5 chain and the adhension rate of podocytes possibly via TGF-β1 signaling pathway. Such alterations may contribute to glomerular podocyte injury associated with the GBM abnormality caused by the imbalance between matrix synthesis and degradation.

Objective To study the clinical efficacy of intra-arterial thrombolysis with recombinant tissue plasminogen activator (rt-PA) for the treatment of ischemic cerebrovascular disease caused by cerebral thrombosis. Methods A total of 245 patients accepted by our hospital during May 2013 and July 2015 were divided into the observation group (n=148) and the control group (n=97). All patients were given conventional process for controling blood pressure and blood lipids. Patients in observation group received intra-arterial thrombolysis with rt-PA, while patients in control group accepted conventional treatment. At the time of admission, the demographic characteristic, vascular influencing factors, baseline clinical findings, laboratory findings and neurological deficits were collected. The improvement of neurological function was evaluated by the modified Rankin scale 3 months after treatment. The levels of fibrinogen (FIB), D-Dimer, activated partial thromboplastin time (APTT) and thrombin time (PT) were measured before and 24 h after the treatment. Results There were no significant differences in demographic characteristic and general clinical data between the two groups ( P>0.05). The proportion of patients with improved neurological function was significantly higher in observation group than that of the control group (83.11%vs. 53.61%, P<0.05). There were no significant difference in coagulation index and fibrinolysis index before treatment between the two groups (P>0.05). Twenty-four hours after the treatment, the levels of FIB, D-Dimer, APTT and PT were significantly improved in the observation group compared with those before treatment. The level of FIB was significantly decreased, D-Dimer was significantly increased, APTT and PT were significantly prolonged in observation group compared with those of control group (P<0.05). Conclusion The rt-PA can effectively dissolve thrombosis and correct the coagulation system and fibrinolytic system.

Objective To explore the stability of unilateral external fixator for tibial fracture in its middle in condition of different distribution and number of screws. Methods The experiment model was made when eighteen human corpse tibial transverse fractures had been fixated with unilateral external fixation, which were divided into six groups. In each group, resistance fragments were adhered to be close to the transverse tibial fracture and near the screw-bone interface(SBI), including three screw distribution models, which were well distributed, close to and far off the fracture site distribution. Each model had also been accomplished according to the conditions of four and six screws before compression load of the same magnitude, the same direction and the same loading position. This method was used to observed the values of strain of SBI and axial displacement at the fracture site at grade load. Results ① Under compression condition, the models displacements and the force at Y-axial were the smallest when screw distribution was even in four or six screws and much better than those of four screws. ② The stability at the condition of six screws was stronger than that of four screws. Conclusion The even distribution of four screws is reasonable when tibial fractures are treated with unilateral external fixation, and six screws can be choosen if conditions permit.
