Hemodynamic situation is an important factor of recurrence of postoperative carotid artery aneurysm. In order to investigate the hemodynamic factors of postoperative carotid artery aneurysm affect carotid artery aneurysm recurrence, we established a 3D finite element carotid artery aneurysm for the preoperative and postoperative periods using the three-dimensional reconstruction techniques. And then we measured the hemodynamic factors of carotid artery aneurysm of preoperative and postoperative by the finite element method. The carotid artery aneurysm model has an accurate and realistic shape; the pressure of the recurrence of aneurysm was reduced significantly after surgery,wall shear stress increased significantly at residual neck, and blood flow velocity increased significantly, which will increase the risk of recurrence. The hemodynamic analysis provides a reference for development of aneurysm clinical treatment programs and prevention of recurrence.

OBJECTIVETo investigate the expression of BATF, a member of the activator protein-1 family, in the renal tissues of mice with lupus nephritis.
METHODSThe renal tissues from 24-week-old female MRL/lpr mice and age- and sex-matched C57BL/6 mice were examined for BATF protein expressions using Western blotting and for expressions of BATF, RORγt and IL-17A mRNA using quantitative real-time PCR. The results of laboratory examinations were analyzed in relation with the histopathology of the mice.
RESULTSThe urinary protein and ds-DNA levels were significantly higher in MRL/lpr mice than in the control mice (P<0.05). Compared to normal control mice, MRL/lpr mice showed obvious glomerular fibrosis and inflammatory cell infiltrating with significantly increased BATF protein and mRNA expressions (P<0.05) and RORγt and IL-17 mRNA expressions in the renal tissues (P<0.05). In MRL/lpr mice, the expression of BATF mRNA was positively correlated with the RORγt and IL-17A mRNA expressions in the renal tissues.
CONCLUSIONThe renal expressions of BATF protein and mRNA is increased in MRL/lpr mice. BATF may participate in the immunopathogenesis of lupus nephritis by enhancing Thl7 cell response.

Objective:To discuss the safety and curative effect of transurethral plasmakinetic enucleation of prostate(TUKEP) in the treatment of large-volume prostate hyperplasia.Methods:From October 2015 to April 2017, the clinical data of 126 patients with large-volume prostate hyperplasia(weight of prostate>80 g) who admitted to Yuncheng Central Hospital were retrospectively analyzed.Different enucleation methods were used according to weight of prostate: ball enucleation for 80~120 g prostate; divided enucleation for more than 120 g prostate.The clinical data were analyzed and summarized.Results:All 126 patients completed operation successfully.The mean enucleation time, cutting time upon harvesting, intraoperative blood loss and intraoperative mean weight of prostate removed of the 126 patients were (19.4±2.4)min, (61.9±16.7)min, (65.3±47.5)mL and (104.5±23.1)g, respectively.Five cases of them had capsule perforation during operation and indwelling catheter for one week after operation, and unobstructed micturition was recovered after removing the urinary catheter, with no repeated hemorrhage or urinary tract infection.Seven cases received intra-operative blood transfusion, with no transurethral resection syndrome(TURS) during and after operation.These patients were followed up for 1~6 months, 23 cases lost to follow up and 14 cases suffered from temporary urinary incontinence.They received health education and levator ani training and were able to completely control urination during follow-up.The IPSS score, QOL score, Qmax and PVR of the patients after operation were (7.6±1.4)points, (1.7±0.6)points, (20.2±3.1)mL/s and (15.0±9.3)mL, respectively, which showed statistically significant differences compared with before operation( t=15.712, 18.331, -21.382 and 16.380, all P<0.001). All of these indicators were obviously improved than before operation, but there was no statistically significant difference in normal ejaculation before and after operation( P=0.252). Conclusion:TUKEP can radically remove prostate tissue and is an effective and safe surgical method in the treatment of large-volume prostate hyperplasia.

The endothelial-mesenchymal transition (EndMT) is known to be involved in the transformation of vascular endothelial cells to mesenchymal cells. EndMT has been confirmed that occur in various pathologic conditions. Transforming growth factor β1 (TGF-β1) is a potent stimulator of the vascular endothelial to mesenchymal transition (EMT). Aspirin-triggered resolvin D1 (ATRvD1) has been known to be involved in the resolution of inflammation, but whether it has effects on TGF-β1-induced EndMT is not yet clear. Therefore, we investigated the effects of AT-RvD1 on the EndMT of human umbilical vein vascular endothelial cells line (HUVECs). Treatment with TGF-β1 reduced the expression of Nrf2 and enhanced the level of F-actin, which is associated with paracellular permeability. The expression of endothelial marker VE-cadherin in HUVEC cells was reduced, and the expression of mesenchymal marker vimentin was enhanced. AT-RvD1 restored the expression of Nrf2 and vimentin and enhanced the expression of VE-cadherin. AT-RvD1 did also affect the migration of HUVEC cells. Inhibitory κB kinase 16 (IKK 16), which is known to inhibit the NF-κB pathway, had an ability to increase the expression of Nrf2 and was associated with the inhibition effect of AT-RvD1 on TGF-β1-induced EndMT, but it had no effect on TGF-β1-induced EndMT alone. Smad7, which is a key regulator of TGF-β/Smads signaling by negative feedback loops, was significantly increased with the treatment of AT-RvD1. These results suggest the possibility that AT-RvD1 suppresses the TGF-β1-induced EndMT through increasing the expression of Smad7 and is closely related to oxidative stress.
