The herpes simplex virus type 1 (HSV-1) VP22, is one of the most abundant HSV-1 tegument proteins with an average stoichiometry of 2 400 copies per virion and conserved among alphaherpesvirinae. Many functions are attributed to VP22, including nuclear localization, chromatin binding, microtubule binding, induction of microtubule reorganization, intercellular transport, interaction with cellular proteins, such as template activating factor I (TAF-I) and nonmuscle myosin II A (NMIIA), and viral proteins including tegument protein VP16, pUS9 and pUL46, glycoprotein E (gE) and gD. Recently, many novel functions performed by the HSV-1 VP22 protein have been shown, including promotion of protein synthesis at late times in infection, accumulation of a subset of viral mRNAs at early times in infection and possible transcriptional regulation function.

Objective To investigate the possible effects and underlying mechanisms of desferroxamine (DFO) preconditioning against hypoxia in neurons. Methods Cortical neurons were cultured in DFO under ischemia condition of oxygen-glucose deprivation (OGD). Cell viability was determined by cell counting kit-8 (CCK-8) method; apoptotic cell ratio was examined with Hoechst 33342 staining; the morphological change was observed. Middle cerebral artery was occluded with or without DFO administration to establish the cerebral ischemia rat model. Infarct sizes were examined by TIC staining, and the neurological severity score was evaluated. Meanwhile immunofluorescent staining was employed to detect the protein synthesis of hypoxia inducible factor-1 (HIF-1) and erythropoietin (EPO), RT-PCR was performed to detect the mRNA expression of HIF-1 and EPO as well Results Neuronal viability kept in 49% (OGD group was 25%, t =8. 544, P<0. 05), the rate of apoptosis was 38% (OGD group was 30%, t = 4. 409, P <0.05 ) after administration of DFO (post-DFO) , the morphology of neurons improved. In the model of focal cerebral ischenfia of 30 mg/kg group, neurological severity score was reduced, the percentage of brain infarct decreased 8.5% (t=4.649, P<0.05) 3 days post-DFO(vs control). In the 100 mg/kg group, neurological severity score was 7.44 ±0.39 (t=2.903, P<0.05 ) ,5.60±0.47 (t=10.143, P < 0.01 ) ,6.97 ±0.73 (t=3.142, P<0.05 ), the percentage of brain infarct decreased 12. 0% (t=5.056, P<0.05), 32.3% (t =10.993, P<0.01), 10.6% (t =4.385, P<0.05)2,3 and7 days post-DFO(vs control), respectively. Immunofluorescent staining found synthesis of HIF-1α and EPO in cultured cortex neurons after DFO pretreated; HIF-1α and EPO were upregulated in the neurons of rat brain after DFO pretreated. The mRNA of HIF-1α and EPO upregulated in vivo and in vitro. Conclusion DFO preconditioning can protect the brain against ischemic damage, which is related to the protective effect on neurons. The mechanism of DFO preconditioning may be involved in the expression of HIF-1α and EPO in vivo and in vitro.

Background and purpose: Langerhans cell histiocytosis (LCH) is a rare complex reticulocndotheliai disease that often invades the head and neck. There in no consensus of treatment. Radiation is one of the treatment options for the localized lesions. Our aim in the study was to analyze the radiotherapeutic efficacy for LCH in the head and neck region. Methods: 8 patients with eosinophilic granuloma (EG) and 1 case with Hand-Schuller-Christian disease (HSC) were treated with radiotherapy in our hospital from July 2000 to May 2007. Their clinical data were retrospectively analyzed. Results: 5 cases of EG were treated with tumor partial excision and radiation, while the other 3 cases of EG were given radiation alone after biopsy. The HSC was administered with radiation and endocrine therapy. All the patients were followed up for 1.5-8 years. The response rate was 89%. Conclusion: Radiotherapy of LCH is an effective modality, but the optimal dose needs to be further studied.

Objective To investigate the percentage of CD4 + C125 +Tregs in peripheral blood of patients with sepsis and its effect on cell immunity so as to unravel the effect of immunomodulatory therapy on it. Method Fourty patients with sepsis in ICU were randomly (random number) divided into experimental group and control group . The patients of experimental group were treated with Ulinastatin and immunoregulation agent (Thymosin αl) as well. The blood specimens were collected just before treatment, 3 days and 8 days after treatment. The percentages of CD4 + CD25 + Tregs and lymphocyte subsets were detected by using FCM (flow cytometry), and TNF-α, IL-6 and IL-10 assayed by using ELISA, and APACHE Ⅱ scores were calculated. Results Before treatment, the percentage of CD4 + CD25 + Tregs increased, and the number of lymphocytes and the percentage of T lymphocytes decreased, especially the CD4 + T lymphocytes and CD4+/CD8+ decreased more markedly, and the levels of IL-6 and TNF-α increased. After treatment,the percentage of CD4+ CD25 + Tregs was decreased, the number of lymphocytes and CD4 +/CD8 + increased, and the levels of APACHE Ⅱ score, IL-6 and TNF-α decreased especially in the experimental group decreased more significantly (P ＜ 0. 05). Conclusions The percentage of CD4 + CD25+ Tregs in peripheral blood can reflect the immune status of patients with sepsis and become a novel indicator to estimate the progress of sepsis, and the immunity and prognosis of patients. Treating the patients with Thymosin αl and Ulinastatin can raise their immunity, decrease the levels of IL-6, TNF-α and APACHE Ⅱ score and improve their prognosis.
