Objective To assess clinical efficacy of comprehensive treatment on chronic sinusitises (CRS) with neutro?phils infiltration and eosinophilic infiltration as pathological features. Methods A total of 256 CRS patients whose symp?toms were not been improved after surgery (visual analog scale>6,3 months after surgery) were included in this study. Dif?ferent comprehensive treatments were given to the patients according to the different types of cell infiltration. The visual ana?log scale (VAS), Lund-Kennedy and nasal histopathological examination were observed after treatment in patients. Results After different comprehensive treatments, the VAS and Lund-Kennedy were improved in patients with eosinophils infiltra?tion, but the number of eosinophils was not reduced. The VAS, Lund-Kennedy and the number of neutrophils were signifi?cantly improved in patients with mainly neutrophils infiltration. Conclusion According to different immune pathological characteristics, patients of CRS should be given different comprehensive treatments. There is a obvious efficacy for patients with neutrophil infiltration.

Paeoniflorin is the main active ingredient of Chinese herbaceous peony. This study is to investigate the protective effect of paeoniflorin (Pae) on acute brain damage induced by lipopolysaccharide (LPS) in mice. The mice were randomly assigned to the normal control, model control (LPS), as well as groups of paeoniflorin and lipopolysaccharide (Pae + LPS). Then the mice were administered intraperitioneally with normal saline or Pae (10, 30 mg · kg(-1)) once daily for 6 d. One hour after intrapertioneally treatment on the seventh day, each group were injected LPS (5 mg · kg(-1)) to establish the endotoxin lipopolysaccharide inflammation model except the normal group. The mice were sacrificed after 6 h and the brain homogenates were prepared and measured. The malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), total antioxidant capacity (T-AOC), hydrogen peroxide (H2O2), succinatedehydrogenase (SDH), Na(+)-K(+)-ATPase and Ca(2+)-Mg(2+)-ATPase were dectected by the colorimetric method. The levels of HO-1 and Nrf2 protein in subcellular fractions of brain tissue were detected by Western blot. The results demonstrated that the administration with paeoniflorin reduced the levels of the MDA production; significantly increase the activities of antioxidant enzyme (SOD and GSH-PX). In addition, paeoniflorin could enhance the total antioxidant capacity, decrease the level of H2O2, and increase the activities of SDH, Na(+)-K(+)-ATPase and Ca(2+)-Mg(2+)-ATPase. Furthermore, paeoniflorin can increase the expression of HO-1 and activate the nuclear transfer of Nrf2. Taking together, these findings suggest that paeoniflorin alleviate the acute inflammation in mice brain damage induced by LPS, which is related with its antioxidant effect and improvement of energy metabolism.

Objective To explore the efficacy of non-T cell depletion haploidentical hematopoietic stem-cell transplantation for T lymphoblastic lymphoma (T-LL). Methods 3 T-LL patients achieving complete remission received haploidentical bone marrow stem cell transplantation with granulocyte-colony-stimulating factor (G-CSF) mobilized bone marrow grafts from related donor without T-cell depletion. Two of them received a myeloablative conditioning regimen consisting of high-doses of cyclophosphamide and cytarabine with total body irradiation, whereas the other was preconditioned with busulfan, cyclophosphamide and cytarabine. All patients received strengthened phophylaxis regimen including rabbit anti-thymocyte globulin against acute graft-versus-host disease. Results All patients had rapid hematopoietic engraftment with the median time for neutrophil and platelet recovery being 12 days and 13 days, respectively. They are still alive without relapse at a median follow-up of 24 months (range: 9-75 months). Conclusion Treatment related toxicity can be acceptable in non-T cell depletion haploidenfical hematopoietic stem-cell transplantation for T-LL and the patients may achieve long term survival.

Objective To study the expression of plasma oxidized low-density lipoprotein (oxLDL) in children with acute phase Kawasaki disease (KD), and investigate its value for early prediction of coronary artery lesions in KD. Methods Totally 80 children with KD were collected. Children were divided into four groups by the results of echocardiogram of coronary artery in different periods: CAL1 group (children with coronary artery lesions (CAL+) both in acute and sub-acute phase, 8 cases), CAL2 group (children with CAL+in acute phase but recovery normal (CAL-) in sub-acute phase, 10 cases), NCAL1 group (children with CAL-in acute phase but occur CAL+ in sub-acute phase, 10 cases) and NCAL2 group (children with CAL- both in acute and sub-acute phase, 52 cases). The serum samples (before the use of intravenous immunoglobulin) were collected in acute phase. Twenty healthy controls and twenty fever controls were enrolled into the study, and their serum samples were collected. OxLDL was measured by enzyme linked immunosorbent assay (ELISA). They were compared using ANOVA, pairwise comparison LSD-t test. And ROC curve analysis was used to determine the threshold. Results Compared with the control groups,plasma oxLDL levels were higher in children with KD, both CA+and CAL-[(15.0±3.3) mU/L, (12.3±3.5) mU/L vs (9.2±2.2) mU/L, (8.0±2.3) mU/L, F=20.435, P<0.05]. Plasma oxLDL levels were increased more significantly in children with CAL+ than children with CAL- in KD [(15.0 ±3.3) mU/L vs (12.3 ±3.5) mU/L, t=2.28, P=0.002]. There was significant difference in the concentration of oxLDL between the groups of Kawasaki disease (F=5.068, P=0.003). Plasma oxLDL levels were significantly higher in the NCAL1 group than those in the NCAL2 group [(14.5 ±3.8) mU/L vs (11.9±3.3) mU/L, t=2.29, P=0.02], but there were no statistically significant difference between the NCAL1 group and CAL1 or CAL2 group [(14.5±3.8) mU/L vs (15.9±3.9) mU/L, (14.5±3.8) mU/L vs (14.2±2.7) mU/L, t=0.73, 0.20;P=0.41, 0.84]. ROCs analysis indicated that oxLDL≥13.83 mU/L, could be the threshold for the prediction of coronary artery lesions with the sensitivity of 0.607 and a specificity of 0.75. Conclusion OxLDL plays an important role in coronary artery lesions in KD. The coronary endothelial dysfunction is earlier than coronary dilatation, and oxLDL is expected to become a reliable early predictor of coronary artery lesions in KD.
