The level of CD4~+ CD25~+ regulatory T cells was assayed in the peripheral blood from the patients with Graves' disease (GD) by floweytometry.CD4~+ CD25~+ regulatory T cells as a kind of non-specific immune cells appear to have no relationship with thyroid function,however,their lowered number in early GD patients suggests that they seem to play an essential role in the pathogenesis of GD.

Keap1 -Nrf2/ARE pathway plays a wide role of cell protection function in anti-tumor,antistress,anti-apoptosis,anti-inflammatory response.It has become a focus of the neuroprotective effects in nervous system.We will review on the latest research of Keap1-Nrf2/ARE pathways in cerebral ischemia.It will provide a basis for the prevention and treatment of central nervous system.

Objective: To study the method of extracting somatosensory evoked potential better. Methods: This article com-pares an auto-reference, auto-correlative and adaptive interference cancellation theories and techniques (AAA-ICT) used to the single trial of somatosensory evoked potential (SEP) with the traditional superposition averaging. Results: By the intensive study and analysis of the somatosensory evoked potentials from the 80 human subjects whose nervous systems are normal, We can find that the traditional superposition averaging method has its reasonable connotation on the extraction of SEP except the inevitable defects. Conclusions: Meanwhile the AAA-ICT avoids its defects. R implements another jump for the SEP extrac-tion method and has a good clinical application value.

Objective In order to study the level chang e of HSP70 in trauma shock patients as well as to explore the relationship betwe en HSP70 and pathogenesis of trauma shock.Methods Serum HS P70 level in 30 healthy volunteers (rved as normal controls) and 36 trauma shock patients were measured by western blot. Results HSP70 was (4301.3?1155.3) in trauma shock group, 6092.3?1233.5 in the control group, and there was significance divination (P

Objective To detect the role of P-Selectin(P-Sel), vascular endothelial growth factor(VEGF) and nitric oxide(NO) on the etiology of traumatic shock.Methods The levels of plasma P-Sel and VEGF in 43 cases traumatic shock patients and 30 normal controls were measured by means of enzyme linked immuno -sorbent assay (ELISA) and that of No was measured by colorimeteric method.Results (1) The plasma levels of P-Sel, VEGF and NO in patients with traumatic shock were much higher than those in the control (all P

Objective To investigate the effect of methylation inhibitor decitabine (DAC) alone and combination with As2O3 on apoptosis of NB4 cells. Methods NB4 cells were treated with DAC, As2O3 and the combination of them in different concentrations. The cell proliferation was analyzed by MTT assay and the apoptosis of NB4 cells was detected by flow cytometry. Results Both DAC and As2O3 induced time and concentration-dependent cell death, in which the inhabitation rate were 12.18 %, 22.72 %, 35.54 %, respectively, after 24 h, 48 h, 72 h on treatment by DAC at 1 μmol/L and the inhibition rates were increased to 22.14 %, 31.18 %, 45.21 % by DAC at 1 μmol/L. The inhibition rates were 21.09 %, 32.43 %, 44.93 %, respectively, by treating with As2O3 0.5 μmol/L after 24 h, 48 h, 72 h, which were increased to 31.69 %, 41.12 % and 54.27 %, respectively after 24 h, 48 h, 72 h. The inhibition rates were significantly increased by using both DAC and As2O3 with significant differences (P <0.05). DAC and As2O3 in combination produced a greater inhibition of growth against NB4 cells (by treating with DAC 1 μmol/L + As2O3 0.5 μmol/L after 24 h, 48 h, 72 h, the inhibition rates were 42.10 %, 48.75 %, 60.78 %) (P <0.05). In each concentration group and control group the differences were statistically significant (P <0.05). The incubation for 48 h with As2O3 1 μmol/L alone or combined with DAC 2 μmol/L showed apoptosis cells by 5.8 % and 17.3 %. Conclusion Decitabine can significantly inhibit the proliferation of NB4 cells and the apoptosis with synergistic effectiveness can be found when Decitabine combination with As2O3.
