Objective To evaluate smooth muscle protein of 22 kDa (SM22) in the diagnosis of acute intestinal ischemia.Methods 96 healthy adult SD rats were evenly divided into experimental group and control group,with each group subdivided into 6 subgroups,subject respectively to superior mesenteric artery ligation or sham operation.The venous blood samples were extracted from each group rats' right heart atO.5,1,2,4,8,12 h after the operation,for SM22 testing and small intestines tissues for direct immunofluorescence staining of SM22.Results The serum SM22 concentration reached a peak at 4 h (265 ± 15) mg/L,then gradually decreased (P ＜ 0.05).The I-FABP was mainly expressed in the epithelium of intestinal mucosa.During the 4 hours of intestinal ischemia,The number of SM22 positive particles did not change.After 4 hours,the number of SM22 positive granules had gradually decreased compared with the control group (all P ＜ 0.05).Conclusion SM22 mainly exists in the smooth muscle of intestinal,during the ischemic necrosis of the intestinal muscle layer SM22 leaks into blood stream,resulting in high serum levels of SM22 facilitating early diagnosis of acute intestinal ischemia.

Objective To explore the expression of the CENP-W in gliomas and investigate the effects of its invasion. Methods The expression level of the CENP-W in gliomas with varied pathologic grade were detected by immunohistochemical analysis,RealTime PCR,and Western Blotting. U251 cells were transfected with the specific siRNA to repress the CENP-W expression level. The invasion ability of U251 cells were examined by Transwell Chamber assay ,while RAS mRNA and protein levels were detected at the same time. Results The expression levels of the CENP-W in glioma tissues were significantly high and the CENP-W gene could enhance the invasion of U251 cells . The expression of RAS was down-regulated when the expression of CENP-W was repressed. Conclusion The CENP-W has an oncogenic role in human brain gliomas and may regulate the invasion of gliomas by adjusting the RAS signaling pathways.

Objective To evaluate the short-term effect of Pipeline embolization device (PED)for the treatment of unruptured wide-necked intracranial aneurysms. Methods From October 2015 to September 2016,15 consecutive patients with unruptured wide-necked intracranial aneurysm (aneurysm neck and aneurysm body ratio ≥0. 5)treated with PED at the Department of Neurosurgery,the Second Affiliated Hospital of Nanchang University were enrolled retrospectively. Their clinical and imaging data were analyzed. Kamran scale was used to evaluate the embolization rate of aneurysms and the changes of the parent arteries. DSA examination was performed again at 6 -12 months after operation. Results Fifteen PED were implanted in 15 patients with unruptured wide-necked intracranial aneurysms,including 13ophthalmic artery aneurysms,1 posterior communicating artery aneurysm,and 1 cavernous sinus aneurysm. The technical success rate was 100% . Immediately after PED implantation,Karman rating of 15 cases were aneurysm grade 2 embolization,parent artery grade A (grade 2a). DSA examination was performed again at 6 - 12 months after operation showed that 14 patients were aneurysm grade 4,parent artery was grade A (grade 4a). One patient (ophthalmic artery aneurysm)underwent the second DSA examinations at 6 and 12 months after operation showed that the residual development of aneurysms. The aneurysm embolization was grade 3, and the parent artery was grade A (grade 3a). No branch artery occlusion was observed. Non of them had neurological deficit. The modified Rankin scale score was 0 in all 15 patients. Conclusion The use of PED in the treatment of unruptured wide-necked intracranial aneurysms has a higher occlusion rate. Its long-term effect still needs further follow-up.

Isolation and characterization of lung epithelial stem and progenitor cells and understanding of their specific role in lung physiopathology are critical for preventing and controlling lung diseases including lung cancer. In this re-view, we summarized recent advances in classification and research methods of lung epithelial stem and progenitor cells. Lung epithelial stem and progenitor cells were region-specific, which primarily included basal cells and duct cells in proximal airway, Clara cells, variant Clara cells, bronchioalveolar stem cells and induced krt5+ cells in bronchioles, type Ⅱ alveolar cells and type Ⅱ alveolar progenitor cells in alveoli. The research methods of lung epithelial stem and progenitor cells were mainly focused on lung injury models, lineage-tracing experiments, three dimensional culture, transplantation, chronic labeled cells and single-cell transcriptome analysis. Lastly, the potential relationship between lung epithelial stem and progenitor cells and lung cancer as well as lung cancer stem cell-targeted drug development were briefly reviewed.

Objective To study the effect of SNORD47 over-expression on proliferation and invasion of U87-epidermal growth factor receptor (EGFR)vⅢ glioma cells. Methods U87-EGFRvⅢ glioma cells at logarithmic phase were assigned into lenti-SNORD47 group, lenti-NC group and blank control group. The recombinant lentiviruses containing lenti-SNORD47 or lenti-NC were transfected into U87-EGFRvⅢ glioma cells of the lenti-SNORD47 group and lenti-NC group, respectively. Forty-eight h after transfection, the SNORD47 expression in the three groups was measured by real time quantitative PCR. Western blotting was used to detect the protein expressions of matrix metalloproteinase (MMP) 2 and MMP9. The proliferation of U87-EGFRvⅢ cells 4, 24, 48, 72 and 96 h after transfection was evaluated by CCK-8 assay and colony formation assay. Transwell assay and wound-healing assay were used to examine the invasion and migration of these cells. Results The SNORD47 expression in the lenti-SNORD47 group was significantly higher than that in the lenti-NC group and control group (P<0.05). The protein expressions of MMP2 and MMP9 in the lenti-SNORD47 group were significantly decreased as compared with those in the lenti-NC group and control group (P<0.05). At 48, 72 and 96 h after transfection, the optical density and number of cloned cells in the lenti-SNORD47 group were significantly decreased as with those in the lenti-NC group and control group (P<0.05). The invasion and migration abilities of U87-EGFRvIII cells in the lenti-SNORD47 group were significantly suppressed as compared with those in the lenti-NC group and control group (P<0.05). Conclusion SNORD47 could inhibit the proliferative and invasive abilities of U87-EGFRvⅢ glioma cells.
