Objective To evaluate the roles of Toll-like receptor 2 (TLR2),TLR4 and myeloid differentiation factor 88 (MyD88) in immune recognition and immune mediation in sporotrichosis by detecting their expressions in skin lesions of sporotrichosis.Methods Biopsy specimens were obtained from the skin lesions of 19 patients with sporotrichosis and normal skin of 12 healthy human controls.Immunohistochemistry was performed to observe the expressions of TLR4 and MyD88,and real-time fluorescence-based quantitative PCR to quantify the expressions of TLR2 and MyD88 mRNAs.Data were expressed as mean ± standard error.Statistical analysis was done with the SPSS17.0 software.Independent samples t-test was conducted to compare the parameters between the lesional and control specimens.A p-value of less than 0.05 was considered to be statistically significant.Results TLR4 and MyD88 were mainly observed in the whole epidermis except the stratum corneum as well as plasma cells and lymphocytes in the dermis and subcutaneous tissue in lesional skin.However,TLR4 was nearly absent and MyD88 was weakly expressed in the dermis and subcutaneous tissue in normal skin.The expression levels of TLR4 and MyD88 were significantly higher in the lesional skin than in the control skin (TLR4,63.767 ± 3.829 vs.5.167 ± 3.246,t =4.82,P ＜ 0.05; MyD88,57.236 ± 4.744 vs.10.588 ± 1.640,t =3.30,P ＜ 0.05).Similarly,the lesional skin showed significantly stronger expressions of TLR2 and MyD88 mRNAs compared with the normal skin (TLR2,1.974 ± 1.452 vs.1.430 ± 1.073,P ＜ 0.05; MyD88,2.028 ± 2.061 vs.0.688 ± 0.422,P ＜ 0.05).Conclusion Sporothrix may induce the development of sporotrichosis by interacting with host immune system via TLR signaling pathways.

OBJECTIVETo investigate the effectiveness of surgical strategies for Shang Ring circumcision in the treatment of short frenulum praeputii in patients with redundant prepuce or phimosis.

METHODSTotally, 130 cases of short frenulum praeputii with redundant prepuce or phimosis were randomly assigned to an experimental group and a control group of equal number to receive Shang Ring circumcision, the former by transverse incision in the distal penis foreskin and pull-up of the interior board, and the latter by conventional transverse incision and longitudinal suture of the frenulum praeputii. Comparisons were made between the two groups in the surgical duration, intraoperative blood loss, 24 h postoperative pain visual analog score (VAS), postoperative complications, satisfaction with the penile appearance, and the quality of sexual life.

RESULTSThe surgical duration, intraoperative blood loss, 24 h postoperative VAS, postoperative sexual satisfaction, and satisfaction with penile appearance were (4.60 +/- 1.20) min, (2.61 +/- 1.81) ml, 1.73 +/- 0.76, 98.5%, and 98.5%, respectively, in the experimental group, as compared with (21.60 +/- 6.30) min, (11.10 +/- 3.40) ml, 5.37 +/- 1.84, 70.3% and 69.8% in the control, with statistically significant differences between the two groups (P < 0.05). The incidence rates of such major complications as wound dehiscence, infection, and moderate to severe edema were 1.5% (1/65), 3.1% (2/65), and 4.6% (3/65), respectively, in the experimental group in comparison with 12.3% (8/65), 15.3% (10/65), and 30.7% (20/65) in the control, with statistically significant differences between the two groups (P < 0.05). None of patients had any serious complications.

CONCLUSIONShang Ring circumcision by transverse incision in the distal penis foreskin and pull-up of the interior board, with its advantages of shorter operation time, less blood loss, mild pain, fewer complications, and higher satisfaction and acceptance of the patients, can be used as an safe and effective approach to the treatment of short frenulum praeputii.

OBJECTIVETo observe the inhibitory effect of a eukaryotic expression vector expressing human IFN-gamma (pcDNA3.1- IFN-gamma) on HBV replication in hepG2.2.15 cells.

METHODSThe eukaryotic expression vector expressing human IFN-gamma was constructed using PCR and gene recombination technique. hepG2.2.15 cells were transfected with pcDNA3.1-IFN-gamma and the culture supernatant was collected to determine the expression of IFN-gamma protein by ELISA. The HBV DNA copies and the concentration of HBeAg and HBsAg were measured by fluorescence real-time PCR and ELISA kit, respectively.

RESULTSCompared with that of negative control and blank 2.2.15 cells, the concentration of HBeAg in the supernatant of 2.2.15 cells transfected with pcDNA3.1- IFN-gamma were decreased by 49%, and HBsAg concentration was lowered by 35% and 33%, respectively. A significant decrease of HBV DNA copies was observed in pcDNA3.1- IFN-gamma-transfected cells in comparison with the two control cells. No significant differences were noted in all the results between the two control groups.

CONCLUSIONWe have successfully constructed the eukaryotic expression vector expressing human IFN-gamma, which provides a basis for anti-HBV gene therapy using human IFN-gamma.
