This article aimed to study the antigenicity of nucleocapsid proteins (NPs) in six pathogenic phleboviruses and to provide theoretical evidence for the development of serological diagnostic reagents. NPs of six pathogenic phleboviruses were expressed and purified using a prokaryotic expression system and rabbits were immunized with individual recombinant NPs. Cross-reactions among NPs and rabbit sera were determined by both indirect ELISA and Western blotting analyses, and the sera titer was determined by indirect ELISA. Furthermore, sera from SFTS patients were also detected by each recombinant NP as a coating antigen using indirect ELISA. The cross-reactions and the sera titer were subsequently determined. Both the concentration and purity of recombinant NPs of six pathogenic phleboviruses met the standards for immunization and detection. The results of indirect ELISA and Western blotting showed that each anti-phlebovirus NP rabbit immune serum had potential serological cross-reactivity with the other five virus NP antigens. Furthermore, the sera from SFTS patients also had cross-reactivity with the other five NP antigens to a certain extent. Our preliminary study evaluated the antigenicity and immune reactivity of six pathogenic phleboviruses NPs and laid the foundation for the development of diagnostic reagents.

Objective To study the relationship between P16,CyclinD1 and P53 anti-oncogene and the gen- esis of hydatidiform mole.Methods 30 samples of hydatidiform moles and normal early pregnant aborted placenta villi respectively were obtained to detect the P16,CyclinD1 and P53 anti-oncogene expression in two kinds of tissues by using SP immunohistochemical staining.Results Compared with that of normal villi,the expressions of P16,P53 and CyclinD1 anti-oncogene were quite different in hydatidiform moles.The expression of P16 was all positive,while CyclinD1 and P53 were all negative in the chorion of early gestation.A descending tendency of P16 expression was found,while the expression of CyclinD1 showed an ascending tendency.The positive rate of P16,CyclinD1 and P53 expression was significantly different between the groups.It was also observed that there was significant difference between the P16 and the proliferation trophocyte.Conclusion P16,CyclinD1 and P53 anti-oncogene have a close relationship with the genesis of human hydatidiform mole.

Objective To study the effect of different concentration of 1,25-dihydroxyvitamin D3[1,25(OH)2D3] on cell proliferation,differentiation and the expression of vitamin D receptor (VDR) in mouse MC3T3E1 osteoblast.Methods Osteoblast were cultured in medium with different concentrations of 1,25(OH)2D3.Incubated for 48 h,cell proliferation of osteoblast were examined by MTT reduction assay (mono-nuclear cell direc cytotoxicity assay),the osteocalcin (OC) levels in cell medium were detected by ELISA,and the expression of VDR mRNA and protein were examined by using SYBR Green real-time PCR and Western blot,respectively.Results 1.After incubation with 1,25(OH)2D3 for 48 h,the number of MC3T3E1 osteoblast was significantly less than that in control group(P0.05).3.SYBR Green real-time PCR and Western blot results showed that the expression of VDR mRNA as well as VDR protein of osteoblast in 10-8,10-9 mol/L experimental groups were significantly higher than those in control group (Pa0.05).Conclusions Cell proliferation of mouse osteoblast can be inhibited,while the cell differentiation was promoted by 1,25(OH)2D3.1,25(OH)2D3 up-regulated the expression of VDR in mouse osteoblast,which suggested that the VDR signal pathway may play some role in proliferation and differentiation of osteoblast.

AIM:To compare the refractive errors measured by the VISX WaveScan, OPD - Scan Ⅲ and the subjective refraction.
METHODS: Seventy - six patients ( 152 eyes ) were recruited from January 2013 to December 2013. All patients were measured with subjective refraction by the phoropter (NIDEK, RT-5100), objective refraction by the WaveScan ( AMO Company, USA) , OPD-ScanⅢ ( Nidek Technologies, Japan). The sphere, cylinder, axis of the three methods were compared and analyzed.
RESULTS: The sphere measured by WaveScan was lower than that by subjective refraction, the difference was 0. 13±0. 30D (t=3. 753, P<0. 001). For cylinder, the difference was 0. 13±0. 43D (t=3. 664, P<0. 001). There was no significance for sphere, cylinder, and spherical equivalent between OPD - Scan Ⅲ and subjective refraction (P>0. 05). The value of the difference between WaveScan and subjective refraction was 5. 87o±6. 19o for the axis and the difference between OPD-Scan Ⅲ and subjective refraction was 3. 82o±3. 95o. There was statistic significance (t=2. 817, P=0. 006).
CONCLUSION: For sphere and cylinder, WaveScan generated some deviation relative to subjective refraction. The Nidek OPD-ScanⅢ gives more accurate measures of objective refraction when compared with subjective refraction.

Objective To explore the effect of self-management on the psychological distress and coping style in postoperative gastric cancer patients.Methods Totals of 87 gastric cancer patients were randomly divided into control group(n =43 ) and intervention group ( n =44 ).The control group received the routine care and the intervention group received self - management.Distress Management and Cancer Coping Modes Questionnaire were used to investigate the psychological distress and coping style of patients in the second day after operation and the day before discharge,respectively.Results There was no difference in the general information,distress and coping style between the two groups (P > 0.05 ).After the intervention,psychological distress scores of the intervention group was lower than that of the control group [ ( 3.27 ± 1.85 ) vs (4.03 ±1.83)],and the difference was statically significant (t =-2.117,P <0.05).In the dimension of coping style,confrontation scores in the intervention group was higher than that in the control group [ ( 19.86 ± 3.97 )vs ( 17.48 ± 3.33 ) ],and the difference was statistically significant ( t =4.301,P < 0.01 ).Avoidance and suppression,resignation and fantasy scores in intervention group were lower than those in the control group [ ( 10.16 ±3.277) vs ( 11.40 ±2.642),(8.15 ±2.542) vs (8.75 ±2.564),(6.71 ±2.494) vs (8.36 ±2.386),respeetively],and the difference was statistically significant (t =-2.334,-1.069,-3.621,respectively ;P < 0.05 ).Conclusions Self-management can alleviate postoperative distress and improve the coping style of gastric cancer patients afer operation.

BACKGROUNDPancreatic islet cell transplantation is an effective approach to treat type 1 diabetes. However, this therapy is not widely used because of the severe shortage of transplantable donor islets. This study investigated whether mesenchymal stem cells (MSCs) derived from human umbilical cord blood (UCB) could be transdifferentiated into insulin producing cells in vitro and the role of extracellular matrix (ECM) gel in this procedure.
METHODSHuman UCB samples were collected and MSCs were isolated. MSCs specific marker proteins were analyzed by a flow cytometer. The capacities of osteoblast and adipocyte to differentiate were tested. Differentiation into islet like cell was induced by a 15-day protocol with or without ECM gel. Pancreatic characteristics were evaluated with immunofluorescence, reverse transcription polymerase chain reaction (RT-PCR) and flow cytometry. Insulin content and release in response to glucose stimulation were detected with chemiluminescent immunoassay system.
RESULTSSixteen MSCs were isolated from 42 term human UCB units (38%). Human UCB-MSCs expressed MSCs specific markers and could be induced in vitro into osteoblast and adipocyte. Islet like cell clusters appeared about 9 days after pancreatic differentiation in the inducing system with ECM gel. The insulin positive cells accounted for (25.2 +/- 3.4)% of the induced cells. The induced cells expressed islet related genes and hormones, but were not very responsive to glucose challenge. When MSCs were induced without ECM gel, clusters formation and secretion of functional islet proteins could not be observed.
CONCLUSIONSHuman UCB-MSCs can differentiate into islet like cells in vitro and ECM gel plays an important role in pancreatic endocrine cell maturation and formation of three dimensional structures.
