Objective To investigate the correlation between the frequency of myeloid-derived suppressor cells (MDSC) and the frequency of regulatory T cells (Treg) in the peripheral blood in patients with chronic hepatitis B (CHB) and its clinical significance.Methods A total of 45 CHB patients including 23 mild-to-moderate CHB patients,22 severe CHB patients,and 15 healthy controls were enrolled.The frequencies of MDSC and Treg in the peripheral blood were studied using flow cytometry and its correlation with clinical data was analyzed by Sepearman correlation analysis.Results The median frequency of MDSC in CHB patients was 0.414％,which was significantly higher than that in healthy controls 0.226％ (Z=-2.356,P=0.018 9).The frequency of MDSC in CHB patients was negatively correlated with the level of alanine transaminase (ALT) and aspartate transaminase (AST) (r=-0.480,-0.478; both P＜0.01),but had no relations with hepatitis B virus (HBV) viral load (r=-0.049,P=0.75).An increase frequency of MDSC was observed in CHB patients with an ALT of 5 × upper limits of normal (ULN) or less or AST of 3 × ULN or less.The frequency of MDSC in CHB patients was positively correlated with that of Treg (r =0.345,P =0.02).Conclusions The activation and proliferation of MDSC may facilitate and maintain HBV persistent infection.The change of the frequency of MDSC is in line with that of Treg,indicating that immunosuppressive functions of MDSC may be related with the development of Treg in CHB.

Objective To evaluate the role of phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/nuclear factor E2-related factor 2 (Nrf2) signaling pathway in endotoxic shock-induced acute lung injury (ALI) in rabbits.Methods Thirty healthy male New Zealand white rabbits, aged 2 months, weighing 1.5-2.0 kg, were randomly divided into 3 groups (n =10 each) using a random number table: control group (group C), ALI group, and wortmannin group (group W).In group W, wortmannin 0.6 mg/kg (in 0.08 ml/kg dimethyl sulfoxide) was injected via the auricular vein, while the equal volume of normal saline was given in C and ALI groups.And 30 min later, lipopolysaccharide (LPS) 5 mg/kg (in 2 ml of normal saline) was injected via the auricular vein in ALI and W groups, while the equal volume of normal saline was given in group C.The rabbits were sacrificed at 6 h after LPS or normal saline injection.The lung was immediately removed for microscopic examination and for determination of wet/dry lung weight ratio (W/D ratio), expression of phosphorylated Akt (p-Akt) , Nrf2 and heme oxygenase-1 (HO-1) (by Western blot), and expression of Nrf2 and HO-1 mRNA (using fluorescent quantitative real-time reverse transcriptase-polymerase chain reaction).The pathological changes of the lung were scored.Results Compared with group C, the lung injury scores and W/D ratio were significantly increased, and the expression of p-Akt, Nrf2 protein and mRNA, and HO-1 protein and mRNA was up-regulated in ALI and W groups (P＜0.05).Compared with group ALI, the lung injury scores and W/D ratio were significantly increased,and the expression of p-Akt, Nrf2 protein and mRNA, and HO-1 protein and mRNA was up-regulated in group W (P＜0.05).Conclusion Activation of PI3K/Akt/Nrf2 pathway is the regulatory mechanism of the body adapting to the development of endotoxic shock-induced ALI in rabbits.

Objective To study the effect of low frequency electrical stimulation on hormone levels in organs of Chinese tree shrews after death.Methods Giving Chinese tree shrews low frequency electrical stimulation.At 0 h, 3 h, 6 h, 12 h, 18 h, 24 h, 36 h and 72 h after death, the thyroid, liver, spleen were taken,and the levels of endothelin (ET), atrial natriuretic factor( ANF) , thromboxane ( TX) were determined by RIA method.At 0 h after death, midbrain ventral tegmental area ( VTA) of Chinese tree shrews was taken to detect the c-fos expression.Results After electrical stimula-tion, ET, ANF, TX levels in the cadaver organs and VTA c-fos expression of Chinese tree shrews were significantly in-creased than in the control group.The contents were decreasing with the time after death.Conclusions Low frequency e-lectrical stimulation can induce the synthesis and release of hormones in organs and c-fos expression in brain tissue of Chi-nese tree shrews.

Objective To investigate the effects of sevoflurane pretreatment on renal ischemia-reperfusion (I/R)-induced apoptosis in kidney in rats. Methods Thirty pathogen-free male SD rats weighing 220-260 g were randomized into 3 groups (n=10 each):group control (group C);group I/R and group sevoflurane(group S). Renal I/R was induced by clamping the left renal pedicle for 45 min in I/R and S groups. In group S inhalation of 2.2% sevoflurane in O2 was started at 30 min before operation and maintained throughout the experiment.Venous blood samples were taken at 3 h of reperfusion for determination of serum BUN and Cr concentrations. The animals were then sacrificed and the left kidneys were removed for microscopic examination, detection of apoptosis(by TUNEL)and determination of heme oxygenase-1(HO-1) mRNA and protein expression (by RT-PCR and Western blot).Results Renal I/R significantly increased serum BUN and Cr concentrations, apoptotic index(percentage of apoptotic cells) and the severity of necrosis of renal proximal convoluted tubules (0=normal,4=necrosis of whole segment of proximal convoluted tubules).Sevoflurane inhalation attenuated the I/R-induced changes mentioned above.HO-1 mRNA and protein expression was up-regulated by I/R and HO-1 mRNA expression was further up-regulated by sevoflurane inhalation.Conclusion Sevoflurane pretreatment can protect kidney against I/R injury by attenuating cell apoptosis.Up-regulation of HO-1 mRNA expression may be involved in the mechanism.
