Glycoprotein N is encoded by glycoprotein N (gN) gene of herpesviruses. The amino acid composition and expression level of this protein vary among difference species of herpesviruses. According to present studies, gN protein is expressed in cytoplasm of host cells, mainly in endoplasmic reticulum. The gN forms a complex with glycoprotein M in host cells. The complex is involved in the processes of viral replication and inter-cellular infection. Moreover, this protein plays a role in immune evasion from host immune system. The study will provide a theoretical basis for further study of herpesvirus gN gene and its encoded protein.

Objective To study the relationship among apoptosis,NF-KB activation and uPA expres- sion in human colon carcinoma cell line HCTll6 induced by 5-fluorouracil,and to observe the effect of in- hibiting activity of NF-KB by PDTC on apoptosis as well as expression of uPA.Methods Cell apoptosis was analysed by Annexin V-FITC.Fluctuation of NF-KB and uPA was detected by semi-quantitative immuno- histochemistry.Results 5-fluorouracil could induce apoptosis and activate NF-KB.PDTC could significantly increase the apoptosis and suppress the activation of NF-KB induced by 5-fluorouracil.There was a positive correlation between the changes of uPA and NF-KB.Conclusion 5-fluorouracil could induce apoptosis,ac- tivate NF-KB and up-regulate expression of uPA of HCT116 cells.The mechanism of enhanced apoptosis by PDTC may be related to suppressing activation of NF-?B and down-regulating expression of uPA.

OBJECTIVETo study the combination of Mandibular distraction and orthognathic techniques for the reconstruction of adult hemifacial microsomia.

METHODSThe three-dimensional CT reconstruction data was used with Mimics for preoperation design. The osteotomy location, distraction vector, distraction distance were decided before operation with a surgical guider. At the first stage, internal distractor was implanted after ostetomy through an extra-oral approach. The distraction begun 5-7 days after operation with a frequency of 1 mm/day. After distraction, the distractor was maintained for 3-6 months. At the second stage, the distractor was removed. Le Fort I osteotomy was performed in order to correct the cross-bite and improve the facial contour. Usually, bone graft was inserted into the gap after Le Fort I osteotomy. The genioplasty was also performed if necessary.

RESULTS9 cases of adult hemifacial microsomia with severe mandibular deviation were treated. The facial asymmetry were improved greatly. 1 patient suffered an wound infection in the maxillary region after Le Fort I osteotomy and healed uneventfully with wound irrigation.

CONCLUSIONSMandibular distraction combined with orthognathic surgery is an effective procedure for adult hemifacial microsomia with complicated mandibular hypoplasia.

Objective To establish a economic and stable method to induce and culture dendritic cells (DCs) from peripheral blood of human being, and compare with the magnetic activated cell sorting. Methods Monocytes were isolated from health donors peripheral blood mononuclear cells(PBMC) by density gradient separation,cultured and compared with that of cells isolated by the magnetic activated cell sorting or adherent culture,respectively. PBMC were cultured with recombinant human granulocyte macrophage colony stimulating factor (rhGM-CSF) and recombinant human interleukin-4(rhIL-4) for 6 days to induce the growth of DCs. Morphological changes was observed under inverted microscope. Meanwhile, cell viability was tested at the 3rd, 5th, 6th day,respectively. The phenotypes, like CD14, CDla, HLA-DR were analyzed with flow cytometry after PBMC were adherent cultured for 1, 2, 5 h. After adding human recombinant cytokines, the phenotypes of acquired cells surface markers, CD14, CD1a, CD86, CD83 and HLA-DR would be detected and compared with flow cytometry. T cells proliferating activity was determined by allogeneic mixed lymphocyte reaction in vitro. Results After adherent culture for 2 h, the acquired DCs showed typical morphology. Cell viability was decreased at days 5th, 6th[(53.333 ±5.774)%,(38.333 ± 7.638)%] than that at day of 3rd[(68.667 ± 3.215)%, all P ＜ 0.05] with the magnetic activated cell sorting, but with adherent culture method, the difference was not statistically significant (F = 0.737,P＞ 0.05) at days of 3rd, 5th, 6th[(92.667 ± 3.055)%,(94.000 ± 1.000)%,(94.667 ± 1.528)%]. Moreover,compared with the magnetic activated cell sorting, there were differences in cell viability of adherent culture method at days of 3rd, 5th, 6th(t = 9.374, 12.021,12.527, all P ＜ 0.05). Before and after using the magnetic activated cell sorting, the expression of CD14 were (32.457 ± 12.351) %, (41.914 ± 14.858)%, respectively. The difference was not statistically significant(t = 1.295, P ＞ 0.05). After culturing for 2 h, the expression of CD14[(35.267 ± 4.658)%]was higher than those of culturing for 1, 5 h[(15.033 ± 6.189)%, (21.233 ± 4.895)%, all P ＜ 0.05]. Compared with the 1st day[(32.328 ± 14.517)%], the CD14 expression level[(2.200 ± 1.356)%] on surface of DCs was significantly reduced(t = 5.467, P ＜ 0.05) at the 6th day of culturing, the CD1a expression level[(43.371 ±16.250)%] was remarkablely increased than that of the 1st day[(12.300 ± 6.223)%, t = 2.545, P ＜ 0.05];while the expressions of CD86, CD83, HLA-DR[(16.857 ± 5.686)%,(9.343 ± 5.230)%,(72.800 ± 17.881)%] were similar(t = 0.652,1.137,0.907, all P ＞ 0.05) compared with that of the 1st day[(12.550 ± 16.758)%, (6.250 ±1.323)%, (64.671 ± 15.588)%]. In mixed lymphocytes reactions, with increasing of lymphocytes, T lymphocytes proliferating activities were reduced. In the magnetic activated cell sorting, when the ratio of DCs and lymphocytes were 1: 50, 1: 100, cells proliferation ability(1.502 ± 0.055,1.507 ± 0.029) were lower than that of ratio of 1: 10(1.859 ± 0.049, all P ＜ 0.05);in adherent culture method, the ratio of DCs and lymphocytes was 1: 100, the cells proliferation ability(1.545 ± 0.066) was decreased than that of ratio 1: 10(2.015 ± 0.301, P ＜ 0.05). When the proportion of DCs and lymphocytes remained the same, the capacity to stimulate T lymphocyte was similar of the two methods(P ＞ 0.05). Conclusions Comparied with the magnetic activated cell sorting, after culture of PBMC for 2 h the induction of DCs can produce better formed and functional cells, and this method is stable, simple,economic, and is a suitable method for basic and clinical research of DCs in vitro.
