A 54-year-old man diagnosed with chronic lymphocytic leukemia (CLL) was admitted in our department in June 2014. After one cycle of FC chemotherapy, a bone marrow examination revealed normalized lymphocyte count and another acute myeloid leuke-mia (AML)-M5 clone. The patient refused sequential treatment and only received follow-up examination. He had continuous hemato-logically stable disease and died of pulmonary infection on July 2015. After a multidisciplinary team discussion, we confirmed the si-multaneous diagnosis of CLL and AML-M5. Through this discussion,tumor second hit model,tumor evolution model,andtumor heterogeneitywere further defined.

Objective To evaluate the effect of three diamension-digital subtraction angiography (3D-DSA) or computed tomography angiography (CTA) on the patients with ruptured multiple intmcranial aneurysm (MIA). Methods A retrospective study on 21 patients with MIA was performed.After scanning with 3D-DSA or 3D-CTA, three-dimensional reconstruction of MIA was carried out by 3D workstation,then the diagnosis was decided and the treatment plan (endovascular treatment or microsurgery) was selected according to stereoscopic image of MIA. Results (1) 3D-DSA or CTA was performed in 21 patients with subarachnoid hemorrhage (SAH),it was revealed these patients carried with 48 aneurysms,including 35 small aneurysms (25 mm).Not only miero-aneurysms and small aneurysms could be precisely showed,also the size of aneurysmal neck,the relationship of the aneurysm and the parent vessel and contiguous branches by stereoscopic image.(2) According to the standard of classification,9 patients with MIA for gradeⅠ(42.9%),10 for gradeⅡ(47.6%),2 for gradeⅢ(9.5%),0 for gradeⅣ.Endovascular treatment was selected prior to microsargery for those high grade patients.In this group,17 patients with 40 aneurysms underwent endovascular embolotherapy with GDC coils.Twenty four anemysms were completely occlusioned,12 beyond 90%,4 were left without treatment because of their small size.In microsurgery group,3 aneurysrus were totally clipped,1 could not be found during operation.No any treatment was accepted in 2 patients with 4 aneurysms. Conclusions 3D-DSA or CTA,which is very useful for the diagnosis and treatment of MIA,could improve the accuracy of diagnosis of MIA and clearly show the stereoscopic image of MIA,also the relation of sac and parent artery.For those patients with high grade MIA,endovascular treatment was selected prior to microsurgery,pro re nata,used to combine with mierosurgery.

Objective To investigate the effects of morroniside extracted from root-bark of Sambucus williamsii on TNF-α-induced MC3T3-E1 cell inflammation, and explore its mechanism of action including Caspase, MAPK, and NF-κB signaling pathway. Methods MC3T3-E1 cells were cultured in medium containing TNF-α (50 ng/mL) and different doses of morroniside. The cell viability was examined by MTT assay, and the levels of IL-1β and IL-6 in the supernatants were identified by ELISA. The expressions of Caspase-3, Caspase-9, p-ERK, p-JNK, p-p38, p-IκBα, IκBα, and NF-κB on the protein level was tested by Western blotting. Results MTT assay results showed that morroniside could promote the proliferation of MC3T3-E1 cells and protect the MC3T3-E1 cells induced by TNF-α. ELISA results showed that the expressions of IL-1β and IL-6 were inhibited. Meanwhile, morroniside could reduce the expression of Caspase3, Caspase9, p-ERK, p-JNK, p-p38, and p-IκBα protein, and increase IκBα protein expression while there was no significant difference in the expression of NF-κB p65. Conclusion Morroniside has protective effect on TNF-α-induced MC3T3-E1 cells inflammation. The possible related mechanism is that morroniside inhibits the release of inflammatory cytokines, the activation of MAPK and NF-κB pathway, and the expression of Caspase, thereby inhibiting the apoptosis of MC3T3-E1 cells.

· AIM: To investigate the effect of β1-integrin overexpression on the apoptosis of rabbit corneal epithelial cells and the related mechanism. · METHODS: The plasmid expressing β1-integrin-GFP fusion protein was constructed by polymerase chain reaction (PCR), and this plasmid (β1 group) or the empty vector (mock group) was transfected into rabbit corneal epithelial cells, respectively. The expression of β1-integrin-GFP fusion gene was confirmed by reverse transcription-polymerase chain reaction (RT-PCR) and Western blot. The adhesion of transfected cells to extracellular matrix (ECM) proteins was determined by adhesion assay. The apoptosis of rabbit corneal epithelial cells was assayed by Hoechst 33342 staining and DNA ladder. The phosphorylation of mitogen-activated protein (MAP) kinase was examined by Western blot. · RESULTS: Rabbit corneal epithelial cells overexpressing β1 -integrin-GFP fusion gene were successfully established. Compared with mock group, β1-integrin transfection significantly promoted the adhesive of rabbit corneal epithelial cells to ECM proteins such as laminin, fibronectin, collagen Ⅰ and collagen Ⅳ. Β1-integrin overexpression inhibited apoptosis and induced MAP kinase phosphorylation in rabbit corneal epithelial cells (P<0.05).· CONCLUSION: These data suggest that overexpression of β1-integrin confers resistance to apoptosis in rabbit corneal epithelial cells, and MAP kinase pathway may play an important role in this process.
