Objective To evaluate the effectiveness of UV-B radiat io n exclusively on a variety type of leukoderma .Methods In open trail, 45 cases of a variety of leukoderma were randomly selected including preg nant striates (20 cases), stretch marks (1 case), postoperative petechia (4 case s), traumatic petechia (10 cases), radiation petechia (2 cases), generalized vit iligo (6 cases) and leukoderma with unknown cause (2 cases) were treated with Re lume UV-B re-pigmentation generator (photo range 290-320 mm), once per week with an adjusting dose for 3-20 treatments. Results 42 cases c ompleted with followed-up after 14 months of UV-B radiation microphototherapy. 64.3% (27 cases) achieved excellent results, including 10 cases of pregnant str iates, 8 cases of traumatic petechia, 4 cases of postoperative petechia and 5 c ases of peneralized vitiligo. 28.6% patients were satisfied with results (12 ca ses), including 7 cases of pregnant striates, 1 case of traumatic petechia, 1 c ase of generalized vitiligo, 1 case of stretch mark and 2 cases of leukoderma wi th unknown causes. 7.1% (3 cases) had no effect. 33.3% (14 cases) required suppl emental treatment after 2-5 months of the initial therapy. Conclusion The UV-B radiation microphototherapy is effective in restoring pigmenta tion in those affected by a variety of leukoderma except radiation petechia. The result of repigmentation is related to the type of leukoderma.

Objective To analyze the relationship between genotype and phenotype of vitelline macular dystrophia (VMD2) gene in a family with Best disease, and to provide the theoretical basis for gene diagnosis of Best disease. Methods Mutation in the coding regions and the promotor sequence of VMD2 gene from 10 members in a family with Best disease were screened by polymerase chain reaction (PCR) and direct DNA sequencing, and combined with a conformation sensitive gel electrophoresis (CSGE) approach, VMD2 gene screening was performed on 100 normal control individuals. Results In the 10 members, T→C nucleotide change at the 223 base of exon 3 was detected in 9, including 6 with Best disease who was confirmed by ophthalmoscopy and electrophysiological examination in whom 2 were affirmed as having homozygote of this mutation. Other 3 young family members with VMD2 gene mutation only had abnormal electro-oculogram manifestations. Above mutation was not detected in the normal control individuals. Conclusions The phenotype and genotype of VMD2 in the family with Best disease is highly correlated. Mutation in VMD2 gene is the nosogenesis in this family. Mutation screening of VMD2 gene can be used for genic diagnosis and genetic consultation of Best disease.

Objective:To analysis the Mimotopes of the peptide mimics to PGN using online softwares.Methods: Mimotopes of PGN were screened from 12-mers linear phage display peptide library by using anti-PGN McAb and the antigenicity of selected clones was identified by ELISA.The B cell epitopes,T cell epitopes of ′GRWxHxVxWAGL′ were estimated by DNAstar and online softwares.Results: 16 phage clones that bound with anti-PGN McAb were screened from 12-mers linear phage display peptide library.Among these positive clones,phage clones No.39 shared the conserved sequence:WxHx……AGL found in previous clone No.31(ATWxHxLxSAGL),which provoked an effective protective immunity against infection with S.aureus.To enhance the stability of the conformation as well as adding biotin on the N-ter-minal as a tag,the sequences ′39′ were redesigned and synthesized by adding S(serine)A(alanine) and GG(glycine)on the C-terminal of origin sequence(named SP39).Next,we estimated or predicted antigenic epitopes,T cell epitopes and scores binding to MHC of these peptides by using DNASTAR and online softwares(http://bio.dfci.harvard.edu/Tools/antigenic.pl,www.syfpeithi.de,http://www.darrenflower.info/mhcpred),indicating that SP39 contains sites bound both mice and human MHC.The sequences ′WxHxVxW-′ may be antigenic epitope as SP39,which contains a T cell epitope.Our results showed that both SP39 could bind to both anti-PGN McAb and a polyclonal antibody against S.aureus.Moreover PGN could inhibit the binding of SP39 to the anti-PGN McAb.These data indicated that SP39 mimic to epitopes on PGN.Conclusion: SP39(GRWxHxVxWAGLAGGS) probably display the mimotopes of PGN.

Objective To observe the efficacy and safety of sorafenib in the treatment of the unresectable hepatocellular carcinoma.Methods According to the inclusion criteria,33 patients with the unresectable hepatocellular carcinoma were given sorafenib (400 mg for twice per day).During the course of treatment,dose was adjusted based on the degree of the adverse effects.Tumor response to sorafenib and safety was assessed every 6-8 weeks using the modified RECIST criteria.The survial curve for the time to progression (TTP) and overall survival (OS) were estimated.Results In this series,there was no patients achieved complete response (CR) and partial response (PR),1 1 patients were evaluated as with stable disease(SD),22 patients were with progressive disease (PD).The median TTP was 5.6 months (2.3-8.9 months).The median TTP was longer in patients with BCLC B than BCLC C stage.TTP was longer in good than in poor performance status patients,and shorter in extrahepatic metastasis than in no extrahepatic metastasis patients.The overall incidence of adverse events was 75.8％.The most common adverse events were hand foot skin reaction,diarrhea,hypertension and rash.Three patients had grade 3 adverse events.Conclusions Sorafenib can extend the median time to progression in patients with unresectable hepatocellular carcinoma.Patients with earlier stage of HCC and better performance status are hopeful for more positive response to the treatment of sorafenib.

Objective To observe the effects of Grifola frondosa polysaccharide on T cell subsets and Th1/Th2 subsets of spleen deficiency mice, and investigate its immunoregulation mechanism. Methods Forty-eight KM mice were divided into 6 groups:normal group, spleen deficiency group, positive group (lentinan), three dosage groups of Grifola frondosa polysaccharide, 8 mice in each group. The mice were injected corresponding drug intraperitoneally for 10 days. Then mice in each group were detected CD3+, CD4+ and CD8+T cell by flow cytometry. IFN-γ and IL-4 levels were detected by ELISA. Results The high dose of Grifola frondosa polysaccharide could significantly increase the CD4+T lymphocytes percentage in peripheral blood (P<0.05). Medium and high dose of Grifola frondosa polysaccharide could significantly increase CD4+/CD8+T cell ratio (P<0.01) and CD3+T lymphocyte percentage (P <0.01) of spleen deficiency mice. Medium and high dose of grifola frondosa polysaccharide could significantly increase IFN-γ level in serum of spleen deficiency mice (P<0.01), and high dose of Grifola frondosa polysaccharide could decrease IL-4 level in serum of spleen deficiency mice (P<0.01). Conclusion Grifola frondosa polysaccharide can improve the decreased CD4+/CD8+T cell ratio which caused by spleen deficiency, and promote the transformation of Th1 to Th2, thus treating spleen deficiency syndrome.
