Objective To investigate the effects of recombinant human augmenter of liver regeneration (rhALR) on renal inflammation in acute kidney injury (AKI) induced by renal ischemia reperfusion (IR). Methods SD rats were randomly divided into sham-operated group,IR group,rhALR1 group (100 μg/kg) and rhALR2 group (200 μg/kg).Both renal pedicles of rats were identified and occluded with microvascular clamps for 60 min to induce acute kidney injury (AKI).Blood urea nitrogen and serum creatinine levels were evaluated using a Hitachi 747 automatic analyzer. For histological examination, sections were stained with HE. The activity of myeloperoxidase (MPO) was detected by spectrophotometer.Expression of TNF-α,ICAM-1,MCP-1 was determined by Western blotting. Results Blood urea nitrogen,serum creatinine levels and the injury of kidney were improved significantly in rhALR group as compared with IR group (all P＜ 0.05).They were improved more significantly in rhALR2 group as compared to in rhALR1 group (all P＜0.05).The protein levels of TNF-α,ICAM-1,MCP-1 and the activity of MPO in kidneys from the sham-operated rats were low,and increased significantly after renal ischemia reperfusion injury (all P＜0.05).After treated with rhALR,the expression of TNF-α,ICAM-1,MCP-1 and the activity of MPO were decreased significantly in kidneys as compared to those in IR group (all P＜0.05),which decreased more significantly in rhALR2 group than those in rhALR1 group (all P＜ 0.05). Conclusions nhALR can protect kidneys from ischemia reperfusion injury in rats.The mechanism may be associated with the inhibition of renal inflammatory cells infiltration and down-regulated expressions of YNF-α,ICAM-1 and MCP-1 in the kidney.

Objective To investigate the effectiveness and safety of endovascular embolization for the treatment of middle cerebral artery aneurysms. Methods From March 2007 to May 2015,the clinical data of 170 patients with 173 middle cerebral artery aneurysms treated with endovascular embolization at the Department of Neurosurgery,Nanjing Jinling Hospital were analyzed retrospectively,including 120 (69.4%)ruptured aneurysms and 53 (30. 6%)unruptured aneurysms. The incidence of complications and prognosis were compared between the 2 groups. Results (1)A total of 170 patients who could perform endovascular embolization after preoperative evaluation successfully completed the interventional procedure. None of the patients died. (2)18 patients (10. 6%)had intraoperative and postoperative complications,including 4 (7. 5%,4/53)in the unruptured aneurysm group and 14 (11. 7%,14/120)in the ruptured aneurysm group. There was no significant difference in the incidence of complications between the two groups. (3)101 patients were followed up for 3-48 months. No new nervous system symptoms and reruptured aneurysm were observed. One patient had recurrence in the unruptured aneurysm group and 4 had recurrence in the ruptured aneurysm group. Conclusion Endovascular treatment of middle cerebral artery aneurysms is a safe,effective,and feasible technique.

Objective Toinvestigatetheapplicativevalueof3D-DSAandheadMRIorCTfusion technology for guiding the individualized treatment of intracranial arteriovenous malformation (AVM ). Methods Twenty-onepatientswithAVMdiagnosedwithDSAattheDepartmentofNeurosurgery,Nanjing General Hospital of Nanjing Military Command from January 2015 to May 2015 were analyzed retrospectively. All patients performed DSA,MRI,and CT scan respectively before procedure,and they also performed 3 D-DSA and MRI or CT fusion. Of the 21 patients,15 performed MRI and 3D-DSA fusion,6 performed CT and 3D-DSA fusion. According to the image fusion results of the patients,the individualized treatment regimens were further developed,including microsurgical resection,endovascular embolization,and stereotactic radiotherapy (alone or combined treatment). The patients were followed up and observed for 2 to 6 months after procedure.Results Fromthe3D-DSAwithheadMRIorCTfusionimagesofthepatientsbeforetheprocedure not only could observe the vascular architecture of AVM,the relationship between the niduses and the surrounding nerve structures,but also could precisely locate the positions of AVM with small aneurysms or tiny AVMs. According to the results of image fusion,17 patients with AVM were treated with microsurgical resection,2 were treated with interventional embolization and stereotactic radiotherapy,and 2 were treated with stereotactic radiotherapy only. Of the 17 patients with AVM underwent microsurgical resection, none experienced intracranial rebleeding during the follow-up period. The last Glasgow outcome scale (GOS)score was 5 in 13 cases,and 4 in 4 cases. One patient with AVM underwent combined stereotactic radiotherapy had intracranial rebleeding during the follow-up period,and their last GOS score was 4. The other remaining 3 patients did not have new neurological deficits or rebleeding during the follow-up period,and theirGOSscorewas5.Conclusions 3D-DSA,headMRI,andCTfusiontechnologyarenovel, the operative method is simple,and the fusion image is accurate. They can effectively develop the individualized treatment regimens for patients with AVM.

Objective To investigate the effect of parent artery occlusion with liquid embolic agents (Onyx)for the treatment of distal intracranial aneurysms.

Purpose To analyze the high-frequency sonographic images of lymph nodes in mesenteric lymphadenitis of different ages. Materials and Methods 139 children with mesenteric lymphadenitis (study group) and 60 normal children (control group) were divided into 1 to 5 years, 6 to 10 years and 11 to 15 years group, the characteristics of high-frequency ultrasound sonographic images were analyzed, accuracy of longitudinal diameter (L), transverse diameter (S), aspect ratio (L/S) and color Doppler blood flow signal classification for the prediction of mesenteric lymph nodes swelling were evaluated using receiver operating characteristic (ROC) curve. Results Mesenteric lymph nodes in the control group appeared as spindle shape with sparse blood flow signals, L, and L/S increased with age increasing (F=4.047, 9.586;P<0.05). Mesenteric lymph nodes in the study group displayed as oval or teardrop-shaped with rich blood flow signals, L, S and L/S did not change significantly with age increasing (F=0.184, 1.084, 2.083; P>0.05). Compared with the control group, blood flow signals were more abundant in all age groups of the study group, L and S were also significantly higher (L:t=-13.798,-12.813,-8.089;S:t= -8.212,-13.172,-9.606, P<0.01), only in the 1 to 5 years group statistically significant difference (t=-3.208, P<0.05) was showed between the two groups. From 1 to 5 years, the sensitivity and specificity for the judgment of lymph node swelling were 95.56%and 100.00%, respectively when using L=9.85 mm as a standard;from 6 to 10 years, the sensitivity and specificity for the judgment of lymph node swelling were 95.59%and 100.00%, respectively when using L=10.25 mm as a standard;from 11 to 15 years, the sensitivity and specificity for the judgment of lymph node swelling were 92.31%and 100.00%, respectively when using S=4.40 mm as a standard. Conclusion High-frequency ultrasound is able to display the location distribution and morphological characteristics of the mesenteric lymph nodes in children, and also to accurately measure the diameters and flow signal distribution of the lymph nodes, thus will provide valuable evidence for the diagnosis of pediatric mesenteric lymphadenitis.

Objective To investigate the imaging features of sarcomatoid carcinoma(SC)of lung on chest radiography and CT and to improve knowledge of SC.Methods The chest plain films,CT images and clinical data of all 7 cases of pathologically proved lung SC were retrospectively analyzed.Results All cases presented with a spheroid solid lung mass ranged from 3 to 11 cm in diameter(average 7 cm).All the lesions were located in middle and lower fields of the lung:3 lesions in right lower lobe,2 in right middle lobe,and the other 2 in left lower lobe.Among the 7 cases:6 cases were of peripheral type and 1 case was of central type.The peripheral-typed lesions of 5 cases had clear margin and 3 of them were lobulated.Three massess were homogenous in density,and the other 4 were inhomogeneous in density with formation of central cavity or calcification.After intravenous contrast administration.Three lesions showed homogeneous enhancement,and the other 4 lesions had inhomogeneous enhancement.The lesions with diameter larger than 6 cm showed marginal or patch-like enhancement.Five cases had pleural or chest walls invasion.Two cases had mediastinal lymph nodes metastases.One case had multiple remote metastasis.Conclusion There are some relatively specific features of lung SC on chest radiography and CT,which may be helpful for diagnosis.

Background Epithelial-mesenchymal transition (EMT) is a major event in the pathogenesis of posterior capsular opacification (PCO),and the expressions of α-smooth muscle actin (α-SMA) is the marker of EMT.Previous studies showed that breviscapine plays an important role in anti-fibrosis and suppression EMT,however,the mechanism of its effect on EMT in LECs is unclear.Objective Present study was to investigate the effect of breviscapine on the expression of α-SMA and fibronectin (FN) in human LECs induced by transforming growth factor-β2 (TGF-β2).Methods Human LECs strain,HLE-B3,was cultured and passaged in DMEM containing 10％ fetal bovine serum.Different concentrations of breviscapine (6.75,12.75,25.00,50.00 and 100.00 mg/L)were added into the medium for 24,48 and 72 hours respectively,and then cell cunting kit-8 (CCK-8) was used to evaluate the half maximal inhibitory concentration (IC50) of breviscapine to HLE-B3.In addition,HLE-B3 was subcultured at the density of 1 × 106/hole and divided into 4 groups.The cells were in free-serum medium as the normal control;the cells were exposed in 10 μg/L TGF-β2 as TGF-β2 group;while in the breviscapine group,10 mg/L of breviscapine was added into the culture medium and another group was the combination of 10 mg/L breviscapine and 10 μg/L of TGF-β2 treatment.Real-time PCR and Western blot were used to detect the mRNA expressions of α-SMA and FN as well as their protein in HLE-B3 72 hours after cultured.Results The inhibitory rate of breviscapine to HLE-B3 proliferation was gradually elevated with the increase of concentration of breviscapine,showing a significant inhibition of the cell proliferation among the different groups and at various time points (F =292.851,P=0.000;F =65.037,P=0.000).IC50 of HLE-B3 at 72 hours was 22 mg/L,and therefore,in rest of experiment 10 mg/L of breviscapine was used which was 1/2 only half of the IC50.α-SMA and FN were expressed in cultured normal HLE-B3.The expressing level of α-SMA mRNA and FN mRNA in the HLE-B3 was significantly different among the normal group,TGF-β22 group,breviscapine treatment group and combination group as well as at various time points (F =105.490,P =0.000 ; F =1041.414,P =0.000).Similarly,the protein expressions of α-SM A and FN in the HLE-B3 was significantly different among the four groups and different time points (F=136.872,P=0.000;F=119.820,P=0.000).The expression levels of α-SMA and FN mRNA and their proteins in HLE-B3 were remarkably increased in the 10 μg/L TGF-β2 group compared with the normal control group (at all P=0.000),and those in the combination group were obviously declined in comparison to the TGF-β2 group (P =0.001,0.001,0.001,0.010).No significant difference was found in the expressions of α-SMA and FN in the HLE-B3 between the breviscapine group and normal control group in both transcriptional level and protein level (P =0.551,0.292,0.551,0.360).Conclusions 10 mg/L breviscapine can arrest the proliferation and EMT of human LECs.This result suggests that using breviscapine may be a potential prophylactic approach in the prevention of PCO.
