Objective To observe and analyze the clinical efficacy of docetaxel and S-1 in treatment of anthracycline-resistant triple-negtive breast cancer(TNBC).Methods 64 cases with TNBC admitted in People' Hospital of Shaoxing City from June 2009 to June 2011were selected as research object.The clinical data of these cases were analyzed retrospectively.Anthracycline had been used to treat the cases, but with no effect or recurrence.Then docetaxel combined with S-1 was applied to the cases.Clinical efficacy and adverse reactions of the chemotherapy were observed and analyzed. Results After treatment,the efficiency of 64 cases was 54.69%,and the disease control rate was 79.69%.During the treatment,the main adverse reactions were gastrointestinal reactions and bone marrow suppression,without death,and patients could tolerate the adverse event.Follow-up results showed that the median time of progression was 10.5 months.After two years,progression-free survival rate was 0.Conclusion Docetaxel combined with S-1 has good clinical efficacy for anthracycline-resistant triple-negtive breast cancer,with relatively mild side effects,which may be an ideal adjuvant chemotherapy method.

Objective To investigate the involvement of apoptosis in the lesions of patients with psoriasis. Methods The apoptosis was detected with terminal deoxynucleotidyl transferase mediated dUTP biotin nick end labeling (TUNEL), and the expression of p53, PCNA and apoptosis suppressing protein bcl 2 was assessed with immunoperoxidase technique in psoriatic lesions and normal skin. Results A large number of keratinocytes showing biochemical and morphologic features of cells undergoing apoptosis were observed in all the suprabasal layers of the psoriatic epidermis. The plaques from all patients analysed showed marked increase in the number of PCNA positive cells in the middle and basal keratinocytes, and a dramatic reduction in the number of bcl 2 positive cells in the basal cell layer. Conclusion The increased apoptosis of keratinocytes in the lesions of psoriasis might be a homeostatic mechanism to the hyperplasia of cells.

Objective To construct the pCDNA3.1-ING4 eukaryotic expression vector and investigate its effect on the proliferation of melanoma cell line M14. Methods The targeted cDNA fragment encoding ING4 was cloned by reverse transcription-PCR with normal gastric mucosa from patients with gastric ulcer, and subcloned into eukaryotie expression vector pcDNA3.1. PCR and DNA sequencing were performed to identify the eukaryotic expression vector pCDNA3.1-ING4, which was then transfected into M14 cells with Lipofectamine 2000 reagent. The expression of ING4 was detected in untransfected, pCDNA3. 1-ING4-transfected and pcDNA3.1-transfected M14 cells by Western blot and immunocyto-chemistry, and cell proliferation by MTT assay. Results A fragment of expected size (750 bp) was amplified by PCR analysis, and DNA sequencing confirmed the correctness of the recombinant plasmid. As shown by immunocytochemistry, the percentage of cells positive for ING4 protein was significantly higher in pCD NA3. 1-ING4-transfected MI4 cells than in non-transfected M14 cells and pcDNA3.1-transfected M14 cells (71.80%±9.88% vs 4.20%±3.35%, P < 0.01). Western blot also revealed an increased expression of ING4 in pCDNA3.1-ING4-transfected cells. Decreased cell viability was observed in ING4-transfected cells compared with nontransfected cells and pCDNA3.1-transfected cells (both P < 0.01). Conclusions The pCDNA3. 1-ING4 eukaryotic expression vector has been constructed successfully, and M14 cells transfected by this recombinant plasmid could effectively express ING4 protein, which may inhibit the cell proliferation of M14 cells.

Objective:To detect genetic mutations in a case of severe epidermolysis bullosa simplex.Methods:Clinical data and peripheral blood samples were collected from the patient and her parents, and genomic DNA was extracted. Whole exome sequencing was performed to identify causative gene mutations in the patient, and then Sanger sequencing to verify the mutations among the family members.Results:A heterozygous mutation c.1429G>A at position 1429 in exon 7 of the KRT5 gene was identified in the patient, which led to the substitution of glutamic acid by lysine at amino acid position 477 (p.Glu477Lys) of keratin 5 encoded by the KRT5 gene. The mutation was not detected in her unaffected parents.Conclusion:A causative mutation c.1429G>A (p.Glu477Lys) in the KRT5 gene was identified in the patient with severe epidermolysis bullosa simplex, which was a de novo mutation.

DNA priming by IDE resulted in higher levels of neutralizing antibody in mice than those by IME delivery . Higher levels of HAI and anti-NA antibodies as well as NA-specific T cell responses were induced by pVRC-based DNA prime than those by pIRES-based DNA prime .HA-specific T cell responses were also enhanced in mice primed with pVRC-based DNA than those primed with pIRES-based DNA by IME .Conclusion The prime-boost strategies by using DNA-based vaccine in combination with rTTV-based H5N1 vaccine could induce humoral and T cell responses in mice against multi-antigens .Immunities induced by vaccines in com-bination might be modulated by various prime regimes .The study provided references for the further develop-ment of novel H5N1 vaccine and the optimization of immunization programs of combined multi-antigen vac-cine candidates .
