Objective To investigate the role of IL-13 in the patients with acute and chronic urticaria. Methods In 22 patients with acute urticaria, 20 patients with chronic urticaria and 19 normal controls, the levels of IL-13, IL-4 and IFN-? of peripheral T lymphocytes were measured by flow cytometry. The serum concentrations of IL-13 and total IgE were tested by ELISA. Results The results of flow cytometry showed that the level of IL-13 of the patients with acute urticaria was significantly higher than that of the normal controls (P

Background Research determined that hypoxia inducible factor-1(HIF-1)is associated with the hypoxia response in normal organ,and it plays an important role during the embryon development.It is also proved that the expression of vascular endothelial growth factor(VEGF)is upregulated in embryon retina.But,whether the action of HIF-1 and VEGF is correlated is unclear. Objective The aim of this study was to investigate the dynamic change of expression of HIF-1α and VEGF in retina during embryonic development and explore the role of HIF-1α and VEGF along with retinal evolvement.Methods The different embryon ages of SD rats were obtained from 30 clean pregnant SD rats by cesarean surgery.The retinas were isolated from embryon 10一day,12一day,14-day,16-day and 20-day rats respectively.The expressions of HIF-1 α and VEGF protein in retina were semi-quantitatively and qualitatively determined by immunochemistry,and the expressions of HIF-l α and VEGF mRNA in retina with different-embryon-phase and adult rats were detected by RT-PCR. Results The hishly level of expression of HIF-1 α and VEGF protein were found in the cellular nuclei and cytoplasm of retina in embryon 10一and 12-day rats.With the increase of embryon age.the expression of HIF-1α and VEGF protein in retina lowed(F=56.70,P<0.01；F=60.78.P<0.01).Compared with the adult rats,the expressions of HIF-1α and VEGF protein in retina were higher from embryon 0-day through 20-day rats(all P<0.01).The significantly positive correlation was found in the expression level between HIF-1α and VEGF protein throughout the experimental duration(r=0.96,P=0.00).Followed the same pattern,the expression levels of HIF-1α and VEGF mRNA in retinas were also enhanced in the embryon 10- and 12-day rats.Identically,a gradually weakened trend was seen in the expressions of HIF-1 α and VEGF mRNA in retinas as the increase of gestational age of rats(F=68.84,P<0.01；F=96.49,P<0.01),and the exDressions of HIF-1 α and VEGF mRNA decreased in the adult rats compared with different embryon-phase rats,showing a statistically significant difference between them(all P<0.01). Conclusion The expressions of HIF-1 αand VEGF in retina appear a dynamic alteration from hish to low during the embryonic development of rat retina,indicating that HIF-1α/VEGF pathway might participate in the process of embryo development of rat retina.

OBJECTIVETo evaluate clinical outcomes of anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) reconstruction under arthroscopy and repair of the injured posteromedial complex structure of the knee joint in the treatment of posterolateral knee dislocation with multiple ligament injuries.

METHODSFrom March 2008 to August 2012,22 patients (16 males and 6 females, ranging in age from 20 to 53 years old, with an average of 30.5 years old) with posterolateral dislocation of the knee were treated with primary reconstruction of ACL and PCL, combined with the repair of injuries in the posteromedial complex and soft-tissue. Eight patients had injuries caused by sports,5 patients road accidents and 9 patients falling down. The ACL was reconstructed using the gracilis and semitendinosus tendons. The PCL was reconstructed using LARS artificial ligaments (14 cases), or gracilis and semitendinosus tendons (8 cases). Suture repair was performed in 17 patients with posteromedial ligament injuries,and self-semitendinosus strengthening operations were performed in 5 patients. Continuouspassive montion (CPM) and active exercises were executed after operation at early stage. The IKDC and Lysholm system were used to evaluate therapeutic effects.

RESULTSAll the patients were regularly followed up, and the duration ranged from 11 to 56 months (averaged, 39 months). According to the IKDC scale,9 patients got a grade A result, 10 got a grade B result, and 3 got a grade C result. The IKDC subject score was 89.6±3.1 and the Lysholm scores was 90.7±1.8 at the latest follow-up, which were both better than those before operation.

CONCLUSIONReconstructing the ACL and PCL and repairing injured posteromedial complex of the knee followed by an active rehabilitation is an effective method to treat posterolateral knee dislocation.

Objective To study the clinical efficacy of bilateral double Z plasties for correction of the webbed neck defects, and to explore its principle and superiority to other reported methods. Methods We designed a small Z plasty over the mastoid with a rhomboidal skin resection of infra-hairline, and another large Z plasty transposition skin flap in superior-acromion. The tight band of fibrous webbing was separately cut and undermined at infra-mastoid and midclavicular line, wherein the middle part of the band retracted medially.Results It involved narrow tunneled anterolateral skin undermining and minimal skin resections from the nape of the neck, and posterior rhomboidal skin excision avoided the unnatural and noticeable lateral scars with normal skin extended in the middle of the webbing.The resultant scar was hidden and mild with no hypertrophic scars. A total of 5 cases were repaired, in which 1 case was male, 4 others were females. Follow-up for 1 to 11 years showed that the appearance and function in the repaired sites by using the bilateral double Z-plasties for repair of webbed neck deformity were very satisfactory. Conclusion We propose the use of this technique for correction of webbed neck deformities with simplified manipulation and cosmetic effect.

Objective:Investigating the expression of HIV-1 co-receptors CXCR4,CCR5 and chemoking SDF-1 in human placentae and trophoblasts is to explore the mechanism of in-utero transmission of human immunodeficiency virus type 1(HIV-1).Methods:Using semi-quantitative reverse transcriptase-polymerase chain reaction,detected the transcripts of CXCR4,CCR5 in placenta tissues and trophoblasts.Immunocytochemistry and immunohistochemistry analysis revealed the expression of CXCR4,CCR5 in primary cultured first trimester trophoblasts and villous tissue.Also the expression of SDF-1 in villi of first trimester,and the presence of SDF-1 in the culture of isolated trophoblasts were examined by in situ hybridization,immunohistochemistry and enzyme-linked immunosorbent assay.Results:CXCR4 and CCR5 mRNA were detected in placentae of various gestational phases and in first trimester trophoblasts.However,primary cultured trophoblasts were found to be reactive only with antibodies against CXCR4.In the villous tissue sections,CXCR4 was found in trophoblasts,while CCR5 in stromal cell and/or Hofbauer cell.First trimester trophoblasts expressed SDF-1 strongly and secreted SDF-1 in vitro.Conclusion:CXCR4 and CCR5 were expressed in placentae.Hence,they maybe involved in in-utero transmission of HIV-1 as co-receptors.However,SDF-1 expressed in trophoblasts may protect fetus from being invaded by X4-HIV-1.R5-HIV-1 may infect CCR5+ stromal cells and/or Hofbauer cells through placental disruptions.
