Purpose To investigate the expression of protein kinase D1 (PKD1) in endometrial carcinoma and normal endometrium,and to investigate its relationship with the clinicopathological features of endometrial carcinoma.Methods Immunohistochemical SP and qRT-PCR was used to detect the mRNA and protein expression of PKD1 in 92 cases of endometrial cancer and 48 cases of normal endometrium,and to analyze the relationship of expression of PKD1 with the tumor differentiation and clinical stage of endometrial carcinoma tissue.Western blot method was used to detect the expression level of PKD1 protein in normal endometrial cell line and endometrial carcinorna cell lines with different degree of differentiation.Results mRNA and protein expression of PKD1 in endometrial carcinoma tissues was significantly higher than those in normal endometrial tissues (P ＜ 0.01),which showing a correlation to the degree of tissue differentiation and clinical pathologic staging.While,the expression level of PKD1 protein in endometrial cancer cell lines was also much higher than that in normal endometrial cells (P ＜ 0.01),and the lower differentiation,the higher level of PKD1 protein expression.Conclusion PKD1 is highly expressed in endometrial cancer patients.The level of PKD1 expression may be an important reference for predicting the malignant degree of endometrial cancer.

The lumbar intervertebral disc is a disc-shaped fibrocartilaginous structure located between the vertebral bodies and acts as an important anatomical structure in the spine for stability. The spinal stability system consists of three subsystems: passive subsystem, active subsystem, and neural control subsystem. Lumbar intervertebral disc degeneration (IVDD), the leading cause of low back pain, induces pathological changes in other tissues of the three subsystems and interacts to degrade spinal stability. IVDD is commonly accompanied by degeneration of facet joint and ligament, Modic change, decreased vertebral blood flow, increased paraspinal muscle fat infiltration, reduced axial tension injury of the nerve, et al. Magnetic resonance imaging (MRI) is the preferred imaging modality for assessing spinal stability. Conventional MRI could completely demonstrate the morphological changes of the three subsystems in IVDD patients, and functional MRI could quantitatively evaluate the degree of pathophysiological change. We summarized the morphological and functional changes of MRI in lumbar intervertebral disc, facet joint, ligament, vertebral body, paraspinal muscle, and nerve of patients with IVDD, and then analysed the changes in spinal stability caused by IVDD, aiming to provide more imaging information for improving diagnosis accuracy and developing appropriate management of patients with low back pain.

Objctive To explore the relationship between the expression of Fas/FasL and the apoptosis occurs in retinal ischemia/reperfusion injury of rats, as well as the therapeutic effects of bFGF on the ischemic retina. Methods The models of retinal ischemia/reperfusion injury was made by transient elevating introcular pressure. A total of 28 rats were divided into normal and operation group.The latter were subdivided into 1 hour, 6, 12, 24, 48 and 72 hours after reperfusion group, in which the left eyes of the rats were in the ischemia/reperfusion groups and the right ones were in the treatment groups (bFGF intracameral injection). Apoptosis was assessed by the terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick-end labelling (TUNEL) method, and the expression of Fas and Fas ligand was studied by strept avidin-biotin complex (SABC)immunohistochemistry. Results No positive cells were observed in the normal rats′ retinae, but there was a significant number of TUNEL positive cells in 6-24 hours after transient ischemia followed by a decrease at the 48th hour. The number of TUNEL positive cells reached a maximum at the 24th hour after ischemia. The expression of Fas gradually increased as early as when it was at the 6th hour, reached a peak at the 24th hour, and then decreased at the 48th hour. Similarly, the expression of Fas ligand was at peak in 24-48 hours in GCL and INL of retina. Conclusions Retinal ischemia-reperfusion after transient elevated IOP induced apoptosis of cells in the retina. Fas/FasL may play an important role in the early events of the apoptotic pathways. bFGF can rescue RGCs from retinal ischemia/reperfusion injury through downregulation of the expression of Fas/FasL and may represent an important mechanism for therapeutic neuroprotection.

Objective To study the evolutionary and mutant characteristics of Ebora virus envelope glycoprotein.Methods A total of 100 Ebora virus envelope glycoproteins amino acid sequences isolated during 1976 and 2014 were collected from National Center for Biotechnology Information (NCBI).Multiple sequence alignment and phylogenetic tree analysis were performed to investigate the evolutionary and mutant characteristics of Ebora virus envelope glycoprotein.Results Glycoprotein amino acid sequences of Ebora virus isolated during 1976 and 2014 showed only 54.00％-65.00％ homology among different subtypes,while 95.00％-100.00％ homology in same subtypes.Ebola virus isolated from different regions in 2014 showed a 99.70％-100.00％ homology of glycoprotein amino acid sequences in the same subtype.The homology of glycoprotein amino acid sequences of Ebola-Zaire virus isolated from Sierra Leone in 2014 was 100.00％,but three strains of Ebola-Zaire virus isolated from Guinea showed diversity in glycoprotein amino acid sequences.Glycoprotein amino acid sequences of Ebola virus with different subtypes were on different branches of phylogenetic tree.Glycoprotein amino acid sequences of Ebola-Zaire virus isolated from Sierra Leone in 2014 were on one branch,and those of Ebola-Zaire virus isolated from other countries during 1976 and 2014 were on the another branch.Conclusions Glycoprotein amino acid sequences of Ebora virus vary with time and region.Ebola-Zaire virus isolated from different regions in 2014 may be two variants with the same origin,and hybrid phenomenon is not observed among virus of different subtypes.
