Objective To screen differentially expressed serum proteins by label-free quantitative proteomics in patients with atopic dermatitis,in order to discover serum protein markers for atopic dermatitis.Methods Serum samples were collected from 6 patients with atopic dermatitis and 6 healthy human controls.Then,the samples from the patients were pooled together,so with those from the controls.Proteins were extracted from the two joint serum samples followed by separation with one-dimensional sodium dodecyl sulfate polyacrylamide gel electropheresis (SDS-PAGE).Peptides were obtained by enzymolysis in protein gels,which were subsequently identified by high performance liquid chromatography tandem mass spectrometry.The Mascot software was used for database searching,and the Scaffold software for relatively quantitative analysis of proteins.Results Totally,76 proteins with a difference of greater than 1.5 folds were identified between the serum samples of patients with atopic dermatitis and controls.There were 50 up-regulated and 26 down-regulated serum proteins in the patients compared with the healthy controls.Among these differentially expressed proteins,26 were only detected in the sera of the patients,and 14 proteins in those of the controls.Conlusion Differences exist in the expression of serum proteins between atopic dermatitis patients and healthy people.

Objective To explore the efficacy of debridement and primary suture for mesh-related infections after tension-free inguinal hernia repair.Methods From January 2007 to December 2013,208 cases with nesh infections following inguinal hernia repairs were treated with debridement in Department of Hernia and Abdominal Wall Surgery of Beijing Chaoyang Hospital,147 cases were treated with primary suture (suture group) and 61 cases were treated with dressing change (open group).Results The mean time of mesh infection was (8.37 ± 6.89) months.The results of bacterial culture in the two groups were similar.First grade healing rate of suture group was 80.95％ (119/147),compared to zero percent in open group.Length of stay [(20.86 ± 7.90) d vs.(31.82 ± 11.50) d,t =3.47,P =0.034] and hospital cost [(3 200 ± 5 800) yuan vs.(26 500 ± 6 600) yuan,t =4.51,P =0.02] in suture group were less than in open group.No patients developed recurrent hernia in suture group compared with one recurrence in open group.Conclusions Debridement and primary suture for mesh-related infections after tension-free inguinal hernia repair could increase the rate of first grade healing,shorten average length of hospital stay and reduce total costs.

Objective To study the effect of pioglitazone on the differentiation and function of rat osteoclast-like cells (OLC), and to probe the relationship between activated PPARγ2 and osteoclasts. Methods On day 1 of OLC formation from nonadherent bone marrow ceils (BMC) obtained from rats induced by M-CSF and receptor activator of NF-кB ligand (RANKL), 1, 5 and 10μmol/L pioglitazone hydrochloride was added. RT- PCR was performed to determine the mRNA expressions of PPARγ2 and receptor activator of NF-кB (RANK) on day 3, 5 and 7 during incubation, the number of tartrate-resistant acid phosphatase (TRAP)-positive cells,the number of bone resorption pits and the ratio of its area on dentin slice were counted, the activity of TRAP and the mean fluorescence intensity of integrin β3 (CD61) of OLC were also measured. Results (1) The effect on the differentiation of OLC: The addition of pioglitazone at the start of the culture period induced a dose-dependent decrease in TRAP-positive OLC and the activity of TRAP (P < 0.01 or P < 0.05) ; the mRNA expression of PPARγ2 was up-regulated by 5 and 10 μmol/L pioglitazone in the early stage of incubation and attenuated with thematuration of OLC on the contrary, however, the expression of RANK was down-regulated by 5 and 10 μmol/L piolitazone in every stage of incubation (P < 0.05 or P < 0.01), combined with decrease in TRAP-positive OLC from day 3 by 10 μmol/L pioglitazone. (2) The effect on the function of OLC: the number of bone resorption pits and the ratio of its area on dentin slice were decreased in groups of 5 and 10 μmol/L pioglitazone (P < 0.01 orP < 0.05), no obvious change was noted in the group with 1 μmol/L pioglitazone compared with the control group; the mean fluorescence intensity of CD61 were down-regulated in groups of 5 and 10 μmol/L pioglitazone (P < 0.05 or P <0.01). Conclusion Activation of PPARγ2 pathway by pioglitazone could partially inhibit differentiation and function of OLC derived from rat BMC.

Objective To study the immune re-constitution after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with hematological malignancies.Methods From June 2011 to May 2015,65 patients with hematological malignancies were analyzed retrospectively.Lymphocyte subsets were determined by flow cytometry (FCM),including total T lymphocytes (CD3+),helper T cells (CD3+ CD4+),cytotoxic T cells (CD3+ CD8+),CD4/CD8 ratio,nature killer (NK) cells (CD3-CD56+),NKT cells (CD3+ CD56+),B lymphocytes (CD19+),naive T cells (CD3+ HLA-DR+),static T cells (CD3+ HLA-DR-),and regulatory T cells (CD4+ CD25high Foxp3+) on the day 14,28 and 42,and on the month 2,3,6,9,12,15,18 and 24 after allo-HSCT.Results The percentage of CD3+ T cells located normal range after hematological recovery,and its absolute number recovered to normal range at + 15 months.The percentage of CD3+ CD4+ T cells recovered to normal range at + 24 months.However,the absolute number of CD3+ CD4+ T cells did not recover to normal range until 24 months after allo-HSCT.The percentage of CD3+ CD8+ T cells was higher than normal range at + 42 day,and its absolute number was greater than normal range at + 3 months.Hence,low CD4/CD8 ratio was observed for a long period.The re-constitution time points of the percentage and absolute number of CD3+ HLA-DR+ T cells were + 3 months and + 24 months respectively.The re-constitution time points of the percentage and absolute number of CD3 + HLA-DR-T cells were + 2 months and + 15 months respectively.The re-constitution time points of the percentage and absolute number of regulatory T cells were + 12 months and + 15 months respectively.The percentage of NKT cells located in normal range after hematological recovery,and its absolute number retumed to normal range at + 12 months.The re-constitution time points of the percentage and absolute number of B cells were + 9 months and + 18 months respectively.The percentage of NK cells located in normal range after hematological recovery,and its absolute number returned nearly to normal range at + 3 months.Conditioning regimen containing ATG,source of stem cells,CD34+ cell number,GVHD,and CMV reactivation were all associated with immune re-constitution after allo-HSCT.Conclusion Different immune cells showed different re-constitution models after allo-HSCT,and the percentage recovered faster than absolute number for a certain kind of immune cells.Studying immune re-constitution and its associated factors may offer beneficial information for insight into transplantation immunology and improve the management of allo-HSCT.
