Objective To investigate changes in expressions of activation antigens CD69 and HLA-DR in CD3+T lymphocytes in peripheral blood and skin lesions in patients with psoriasis vulgaris. Methods Peripheral blood samples were obtained from 20 patients with psoriasis vulgaris and 20 healthy controls, and skin specimens from the lesions of 15 out of the 20 patients and 10 healthy controls. Flow cytometry was performed to quantify the expressions of CD69 and HLA-DR in peripheral blood CD3+T cells, and an immunohistochemical study to measure the expression of HLA-DR in skin specimens. Statistical analysis was carried out by a two-sample t-test and Pearson correlation analysis with the SPSS 19.0 software. Results Compared with the healthy controls, the patients with psoriasis vulgaris showed increased expression rates of CD69 (4.70%± 1.90%vs. 1.56%± 0.95%, t=6.629, P<0.01)and HLA-DR (8.97%± 1.79% vs. 3.02% ± 1.15%, t= 6.204, P< 0.01)in peripheral blood. Pearson correlation analysis revealed that the percentage of CD3+HLA-DR+cells in peripheral blood was positively correlated with the psoriasis area and severity index (PASI)score (r=0.5626, P<0.05). The expression rate of HLA-DR was significantly higher in the dermis (64.87%± 17.31%vs. 19.80%± 5.69%, t=7.916, P<0.01), but lower in the epidermis(11.80%± 5.55%vs. 27.40%± 8.61%, t=5.479, P<0.01)in the psoriatic specimens compared with the control specimens. Immunohistochemically, HLA-DR was widely expressed in the dermis of psoriatic lesions, but mainly distributed around blood vessels in the control skin. Conclusions There is an aberrant activation of CD3+T cells in peripheral blood and inflammatory cells in skin lesions in patients with psoriasis vulgaris, and the percentage of CD3 +HLA-DR+ cells in peripheral blood is correlated with the severity of psoriasis vulagaris.

Aim To investigate the effects of tyrosine kinase inhibitor A77-1726 on IL-13 induced STAT6 phosphorylation and c-fos expression in Dami cell and to provide novel experimental basis to the clinical application of A77-1726 and the study of IL-13 pathway.Methods Total RNA was extracted from Dami cells incubated with or without IL-13 and A77-1726 respectively for various time points.RT-PCR and agar gel electrophoresis were used to examine the expression of c-fos mRNA.The expression of STAT6 and c-fos proteins was detected by Western blot.A densitometric rel-ative quantitation of PCR and Western blot products was quantitated using Image Quant software.Results STAT6 was phosphorylated by treatment of 100 ?g?L-1 IL-13 in Dami cells.Phosphorylation of STAT6 induced by IL-13 was inhibited by treatment of 50?mol?L-1 A77-1726.The expression of c-fos mRNA was significantly induced by IL-13 treatment in Dami cells(P

Expression of HLA class Ⅱ antigens(HLA-DR, DQ and DP), interleukin2 receptors(IL-2R) and transferrin receptors(TfR) of blood monocytes from 10 patients with insulin-dependent diabetes meIlitus (IDDM) were assayed with the indirect immune fluorescence technique using corresponding monoclonal antibodies and the FITC-labelled second antibody. The results showed that the number of HLA-DQ~+ monocytes was much more in diabetics than in normal controls. The percentages of HLA-DR~+ and HLA-DP~+ monocytes in diabetics were not different significantly from those in normal controls. Besides, IL-2R~+ and TfR~+ monocytes were also found to be very much increased in diabetics as compared with controls. It was possible that increased expression of HLA-DQ antigen, IL-2R and TfR of monocytes in patients with IDDM might play a role in the pathogenesis of the autoimmune reaction.

BACKGROUNDTo avoid the irritation of tendons and soft tissues as well as hardware-related problems, we designed an intramedullary fixation with bioabsorbable rods for the treatment of the metacarpal shaft fractures.

METHODSFive patients with nine shaft fractures of the fourth and fifth metacarpi were treated with intramedullary absorbable implants and followed up with an average of 4.2 months postoperatively.

RESULTSAt final follow-up, all patients achieved fracture union with no signs of inflammatory or subcutaneous effusion. There was no shortening, angulatory, or rotatory deformity. There was almost full active extension range of motion (ROM) of the metacarpophalangeal joints while the active flexion ROM of these joints was 80.7 ± 9.6°. Compared with the contralateral hand, the grip strength of the injured hand was 94.0 ± 9.6%. X-rays showed that the arch of the second to fifth metacarpal heads was smooth. There were no intramedullary lytic changes and soft tissue swellings.

CONCLUSIONThe intramedullary absorbable implants are a safe, simple, and practical treatment for fourth and fifth metacarpal fractures with good early clinical outcomes and no significant complications.

OBJECTIVETo investigate the effect of Astragalus in regulating the imbalance between naive helper T cells (Th1/Th2) cytokines expression in patients with cervical cancer.

METHODSThirty patients with cervical cancer received intravenous dripping with 20 mL of Astragalus Injection (AI, contained extract from 40 g of crude drug) per day for 1 week, peripheral blood sample was collected from patients separately before and after treatment for extract mononuclear cells by density gradient centrifugation. The positive percentages of CD4+ interferon-gamma (IFN-gamma ) cell and CD4+ interleukin-4 (IL-4) cell in total CD4+ cells were measured by flow cytometry; the contents of IFN-gamma, IL-4 in culture supernate were detected with ELISA; and the expressions of T-cell transcription factor T-cells (T-bet) and GATA-binding protein-3 (GATA-3) were determined by RT-PCR. The data were controlled by those get from 10 healthy persons.

RESULTSCD4+ IFN-gamma positive cell percentage, T-bet mRNA expression level and concentration of IFN-gamma in supernate were significantly lower in patients than those in healthy control respectively, while CD4+ IL-4 positive percentage, level of GATA3 mRNA expression and IL-4 concentration in supernate were insignificantly different between the two groups. After AI treatment, the lowered parameters were up-regulated (P < 0.05), and no obvious change was observed in the CD4+ IL-4 positive cell associated parameters.

CONCLUSIONTh1/Th2 cell function imbalance existed in patients with cervical cancer, showing a Th2 predominant reaction mode; AI can regulate the imbalance, offset to Th1, thus to display its anti-tumor effect.
