To explore the clinical efficacies of hyperbaric oxygen therapy on the recovery of cognitive function in stroke patients on hemodialysis.Forty stroke patients on hemodialysis were assigned randomly into hyperbaric oxygen therapy (HBO) (n =20 ) and routine therapy groups (n =20).Patients of HBO group received both hyperbaric oxygen therapy and routine therapy.Nerves functions and cognitive function were observed before and after therapy to compare the clinical outcomes.Neuropsychological tests,minimental status examination (MMSE) and activities of daily living (ADL) were used for assessing cognitive function.Then the outcomes were compared with those of the control group.Nerves function and cognitive dysfunction of the treatment group had significant improvement (P ＜ 0.01).Hyperbaric oxygen can significantly improve cognitive dysfunction in stroke patients on hemodialysis.

Objective To investigate the mechanism of tumor necrosis factor-α (TNF)-α inhibiting osteo blastdifferentiation of mesenchymal stem cells (BMMSCs) in the pathogenesis of osteoporosis in the mouse model of systemic lupus erythematosus (MRL/lpr). Methods The femurs of MRL / lpr and C3He/HeJ mice were isolated, the bone structure were examined by hematoxylin-eosin (HE) staining. The proteins of TNF-α, NF-κB P50, bone morphogenetic protein -2 (BMP-2) and PSmad1/5/8 were measured by immunohistochemical stain. Bone marrow mesenchymal stem cells (BMMSCs) were isolated. After BMMSCs grew on the cover slips, the proteins on top of it were evaluated by immunohistochemistry stain. Moreover, the alkaline phosphatase (ALP) staining was employed for the measurement of the early osteogenic differentiation. BMMSCs together with hydroxyapatite were embedded subcutaneously in the nude mice and eight weeks later, the ectopic bone formation was evaluated. The recombinant human tumor necrosis factor receptor type Ⅱantibody fusion protein (etanercept) or normal saline was subcutaneous injected to the mice with lupus. After four weeks, the expression of these proteins was observed and the ectopic bone formation was investigated. Image-Pro plus 6.0 software was employed for imagine analysis, and Studentˊs t-test was used to test the differences between 2 independent groups. Results MRL/lpr mice showed decreased volume of cortex and the percentage of cortex to the volume of bone of MRL/lpr mice was significantly lower compared to control groups and with C3He/HeJ mice (13.96±0.25 vs 23.61±0.71, n=3, P<0.01). The protein levels of both TNF-αand NF-κB P50 on the femur of MRL/lprl mice were higher than those of the control group (0.643±0.051 vs 0.405±0.022, 0.917±0.023 vs 0.650±0.032, n=3, P<0.01). The expressions of BMP-2 on the femur of MRL/lpr mice were lower than those of the C3He/HeJ mice (0.52 ±0.03 vs 0.72 ±0.03, n=3, P<0.01). There was no difference in the expression of PSmad1/5/8 on the femur between the two groups by immunohistochemistry detection (1.264 ±0.021 vs 1.301± 0.044, n=3, P>0.05). The expressions of TNF-α and NF-κB P50 in BMMSCs of MRL/lprl mice were higher than those of the C3He/HeJ (0.184±0.021 vs 0.136±0.013, 0.132±0.021 vs 0.097± 0.014, n=3, P<0.01), while BMP-2 and PSmad were lower than those of the control group (0.128±0.013 vs 0.216±0.221, 0.115±0.023 vs 0.196±0.034, n=3, P<0.01). After 7 days of BMP-2 stimulation, the activities of ALP of BMMSCs from MRL/lprl mice were reduced detected by ALP staining and the osteoblast differentiation of these cells were decreased than BMMSCs from the control mice by HE and Masson staining. The percentage of the cortex to the volume of bone of the etanercept injection MRL/lpr mice was higher than that of the control group (21.8±1.0 vs 14.3 ±0.6, n=3, P<0.01). Moreover, the proteins of TNF-α and NF-κB P50 on the femurs of such injected mice were lower than those of the control group (0.540±0.024 vs 0.682±0.031, 0.857±0.023 vs 1.098±0.044, n=3, P<0.05), while the expressions of BMP-2 were higher than the control group (0.99±0.04 vs 0.85±0.04, n=3, P<0.05). There was no difference in the PSmad1/5/8 expression on the bone of the two group of lupus mice (0.88 ±0.08 vs 0.84 ±0.04, n=3, P>0.05). The ectopic bone formation of BMMSCs of the etanercept injected MRL/lpr mice was higher than that of the normal saline injected mice, however, it was lower than that of the C3He/HeJ mice. Conclusion TNF-α inhibits osteoblast differentiation of mesenchymal stem cells by depressing Smad signaling which may contribute to the osteoporosis of the lupus mice.

Objective To evaluate the accuracy of lymphocyte count as a surrogate for CD4+T cell count in treatment-na(i)ve HIV-infected adults.Methods A total of 2 013 HIV-infected patients were screened at 23 sites in China.CD4+ T cell counts were measured by flow cytometry.Correlation between CD4+ T cell count and peripheral lymphocyte count were analyzed by spearman coefficient.AUCRoc were used to evaluate the performance of lymphocyte count as a surrogate for CD4+ T cell count.Results The lymphocyte count and CD4+T cell count of these 2 013 patients were (1 600±670) × 106/L and (244 ± 148) × 106/L respectively.CDa+ T cell count were positively correlated with lymphocyte count(r =0.482,P ＜0.000 1).AUCROC of lymphocyte count as a surrogate for CD4+ T cell counts of ＜ 100 × 106/L,＜200 × 106/L and ＜ 350 × 106/L were 0.790 (95％ CI 0.761-0.818,P ＜ 0.000 1),0.733 (95％ CI 0.710-0.755,P ＜ 0.000 1) and 0.732 (95％ CI 0.706-0.758,P ＜ 0.000 1) respectively.Conclusion Lymphocyte count could be considerad as a potential surrogate marker for CD4+ T cell count in HIV/AIDS patients not having access to T cell subset test by flowcytometry.

Objective To analyze the correlation between CD4+ T cell count and HLA-DR or CD38 expression on peripheral CD8+ T cells in treatment-naive Chinese HIV/AIDS patients.Methods A total of 471 treatment-naive HIV-infected patients and 53 healthy volunteers were enrolled.HLA-DR or CD38 expression on peripheral CD8+ T cells, CD4+ T cell count, naive CD4+ T cell subsets and CD28 expression on T cells were measured by flow cytometry.Plasma HIV RNA load was quantified by real-time PCR (COBAS TaqMan RT-PCR).Mann-Whitney U test and Spearman's rank correlation test were used for statistical analysis.Results CD38 expression intensity on CD8+ T cells was negatively correlated with CD4+ T cell count (r =-0.53, P ＜ 0.001) and naive CD4+ T cell count (r =-0.48, P ＜ 0.001).CD38 expression on CD8+ T cells also displayed significantly negative correlation with CD28 expression on CD8+ T cells (r =-0.46, P ＜ 0.001).HLA-DR expression on CD8+ T cells did not show significant correlation with CD4+ T cell count.Only weak positive correlation was found between CD38 intensity on CD8+ T cells and plasma HIV RNA load.Conclusions Compared with HLA-DR, CD38 expression on CD8+ T cells shows more significant negative correlation with CD4+ T cell count in treatment-naive patients.CD38 and HLA-DR may play different roles on the persistent immune activation in HIV infection.
