Grass carp reovirus (GCRV), a double stranded RNA virus that infects aquatic animals, often with disastrous effects, belongs to the genus Aquareovirus and family Reoviridea. Similar to other reoviruses, genome replication of GCRV in infected cells occurs in cytoplasmic inclusion bodies, also called viral factories. Sequences analysis revealed the nonstructural protein NS80, encoded by GCRV segment 4, has a high similarity with uNS in MRV(Mammalian orthoreoviruses), which may be associated with viral factory formation. To understand the function of the uNS80 protein in virus replication, the initial expression and identification of the immunogenicity of the GCRV NS80 protein inclusion forming-related region (335.742) was investigated in this study. It is shown that the over-expressed fusion protein was produced by inducing with IPTG at 28oC. In addition, serum specific rabbit antibody was obtained by using super purified recombinant NS80(335.742) protein as antigen. Moreover, the expressed protein was able to bind to anti-his-tag monoclonal antibody (mouse) and NS80(335-742) specific rabbit antibody. Further western blot analysis indicates that the antiserum could detect NS80 or NS80C protein expression in GCRV infected cells. This data provides a foundation for further investigation of the role of NS80 in viral inclusion formation and virion assembly.

Objective To investigate the effects of nitric oxide (NO) and cholecystokinin (CCK) on the regulation of the motility of sphincter of Oddi (SO).Methods The basal pressure,action rate and contraction range of the SO were examined before and after the injection of CCK,sodium nitroprusside (SNP) and NG-nitroL-argininemethyl ester hydrochloride (L-NAME).The expression of neurons with positive expression of NO synthase was detected by immunohistochemical staining.The measurement data were analyzed by using the t test.Results The basal pressure,contraction rate and contraction range of the SO were (27 + 10)mm Hg (1 mm Hg =0.133 kPa),( 10 ± 3 ) times/minute and (32 + 8 ) mm Hg before injection of CCK,and (61 + 14) mm Hg,(64 +21 ) times/minute,(44 ± 15 ) mm Hg after injection of CCK of 20 ng/kg.After injection of CCK of 100 ng/kg,the basal pressure,contraction range and contraction rate of the SO were (77 ± 31 )mm Hg,(69 ± 18 ) times/minutes,(79 + 14) mm Hg when the inhibition effect of CCK reached peak,and were ( 140 ± 21 ) mm Hg,( 129 ± 25 )times/minutes,( 173 ± 63 ) mm Hg when the excitatory effect of CCK reached peak.After injection of SNP into the common bile duct,the basal pressure,contraction range and contraction rate of the SO decreased significantly ( t =3.706,5.183,P < 0.05),while the 3 indexes increased significantly after injection of SNP (t =5.859,3.588,P <O.05).Conclusion Different from physiological dose (20 ng/kg) of CCK,large dose of CCK enhances motility of SO intensively.NO relaxes SO,which may play an important role in the inhibitor pathway of CCK.

To study the inhibitory effect of gigantol on proliferation, migration and invasion of human osteosarcoma U20S cells and to explore the mechanism. Methods: After being treated with different concentrations (10, 25, 50, 75, 100, 150 µmol/L) of gigantol for 24 and 48 h, the proliferation of U20S cells was detected by CCK-8 assay. Transwell assay was used to detect the effects of 25 µmol/L and 50 µmol/L gigantol on the migration and invasion abilities of U20S cells. The lipopolysaccharide (LPS) was used to induce inflammatory reaction in U20S cells before gigantol treatment; qPCR and WB were used to detect the mRNA and protein expressions of NF-κB (p65), TNF-α, IL-6 and PRL-3, respectively. Results: Different concentrations of gigantol could all inhibit the proliferation of sarcoma U20S cells at different time (P<0.05 or P<0.01). The 25 µmol/L and 50 µmol/L of gigantol could significantly inhibit the migration and invasion of osteosarcoma U20S cells (all P<0.01); at the same time, it could inhibit the protein expressions of NF-κB, TNF-α, IL-6 and PRL-3 (P<0.05 or P<0.01). After LPS induction, the mRNA and protein expressions of NF-κB, TNF-α, IL-6 and PRL-3 in U20S cells were significantly increased (all P<0.01); however, the consequent treatment with gigantol (25 and 50 µmol/L) reversed the effects of LPS on U20S cells obviously (P<0.05 or P<0.01). Conclusion: Gigantol can inhibit the proliferation, migration and invasion of osteosarcoma U20S cells, and its mechanism may be related to the regulation of NF-κB/PRL-3 signaling pathway.

Objective:To analyze clinical characteristics, treatment, and prognosis of B-cell lymphoma, unclassifiable, with features in-termediate between diffuse large B-cell lymphoma and Burkitt lymphoma (DLBCL/BL). Methods:The clinical and pathological data of 13 DLBCL/BL patients, who were treated in the First Affiliated Hospital of Zhengzhou University between January 2013 and December 2014, were collected. Overall survival (OS) and progression-free survival (PFS) were estimated by the Kaplan-Meier method. Through the log-rank test, survival curves were compared among groups classified by clinical stage, age, serum lactate dehydrogenase (LDH) lev-el, international prognostic index (IPI) score, or first chemotherapy regimen. Results:Among the 13 patients with DLBCL/BL, 12 pa-tients showed extra-nodal involvement. The median OS and PFS were only 10 and 6 months, respectively. Univariate analysis showed that the LDH levels and IPI scores exerted statistically significant effects on prognosis. Some borderline differences in survival were not-ed among the CHOP, CHOP-like, and intensive chemotherapy groups. Conclusion:DLBCL/BL is an aggressive B-cell lymphoma with a short survival time. The majority of patients presented extra-nodal involvement. DLBCL/BL did not respond well to CHOP or CHOP-like regimen, and more intensive chemotherapy may improve survival. Elevated LDH levels and high IPI scores were predictors of poor sur-vival.

Objective To study the effect of local mild hypothermia on the expression of matrix metallopro- teinases-2/9 (MMP-2/9) and brain edema in experimental intracerebral hemorrhage (ICH) in rat. Methods One hundred and forty-five Wistar rats were randomly divided into a normothermia sham-operation (NSO) group ( n = 15 ), a normothermia intracerebral hemorrhage (NICH) group (n = 75 ) and a mild hypotbermia intracerebral hemor- rhage (MHICH) group (n = 75). Autologous arterial blood was stereotaxically injected into the right caudate nucleus of the rats of the NICH and MHICH groups to make intracerebral hemorrhage model. The rats in the MHICH group were then subjected to 4 hours of local mild hypothermia, while those in the NICH group were under the room temper- ature. The brain water content, permeability of brain-blood barrier (BBB) and expressions of MMP-2/9 were meas- ured by immunohistochemistry method at 6 h, 24 h, 72 h, 5 d and 7 d after operation. Results In NICH group, the brain water content, permeability of BBB and expression of MMP-9 all began to increase at 6 h and peaked at 3 d after injection of blood and still higher than the NSO group at 7 d. The expression of MMP-2 only began to increase little at 24 h and peaked at 5 d after operation and remained highly expressed at 7 d. In the MHICH group, the chan- ges of brain water content, permeability of BBB and expression of MMP-9 were similar to those of the NICH group, but the extent of changes was significantly lower at the every time point. In NICH group and MHICH group, MMP-9 expression was positively correlated with both the brain water content and the permeability of BBB, but MMP-2 ex- pression was not correlated with them. Conclusion Mild hypothermia might protect BBB against injury caused by ICH and relieve brain edema and inflammation reaction through inhibiting the expression of MMP-2/9.

Objective To identify the normal breast tissue and breast fibroadenoma tissue by shell-isolated nanoparticle-enhanced Raman spectroscopy (SHINERS),and to explore the biological characteristics of FD and the identification method by discussing its spectroscope characteristics.Methods The frozen section of 26 patients (all female,aged 19-59 years)were obtained by routine surgical resection.9 cases of normal tissue and 17 cases of breast fibroadenoma tissue were detected by Raman spectroscopy and then SHINERS technique was utilized.A total of 243 Raman and 273 SHINERS spectra were obtained.All the spectra were dealt with baseline corrected by fitting and subtracting a third-order polynomial and then smoothed with a 15-point Adjacent-Averaging.Results The characteristic peaks of normal breast tissue appeared in 1 090,1 157,1 262,1 300,1 442,1 658,1 745,and 1 874 cm-1 .After adding SHINs, some peaks shifted in 2 - 3 cm-1 , the relative strengths of 1 090 and 1 157 cm-1 were significantly increased,and the 1 496 cm-1 characteristic peak appeared.The main characteristic peaks of breast fibroadenoma appeared in 751,880,930,880,1 262,1 442,1 579,1 658,and 1 745 cm-1;one of the dominant characteristic peak should belong to lipids,but it can be seen that amideⅠ characteristic peak of protein became more significant.Conclusion Raman spectra can discover the differences of the characteristic peaks of amide Ⅰ between breast fibroadenoma and normal breast tissues. By virtue of different enhancement effects of SHINs to Raman specific peaks of the various tissues, breast fibroadenoma can be distinguished from normal tissue successfully.
