The cyclic voltammetric behaviors of sodium selenite on the gold electrode modified by L-cysteine self-assembled monolayer (L-Syc,Au/SAMs) has been investigated in 0.05 mol/L H_2SO_4 solutions with sodium selenite. Sensitive anodic stripping current of selenium (Se) with the peak potential at 0.99 V (vs. SCE) has been observed. In comparison with the electrochemical properties of sodium selenite on the modified electrode with those on the naked gold electrode, it was found that selenite was reduced to selenium by the redox interaction with sulfur on the monolayer and the monolayer catalytically oxidizes Se as the electrode was positively scanned. According to the electrochemical properties of sodium selenite both on the naked and modified gold electrode, the Se deposition mechanism and catalytic mechanism as well as bionic membrane model were proposed for the bio-utilization of selenite through nano scale selenium.

Objective To analyze effect of oxycodone hydrochloride injection preemptive analgesia on serum cellular immune factors and analgesic effect in postoperative patients with humeral fracture surgery.Methods 52 patients treated by surgical treatment of humeral fractures in our hospital were collected.All patients were randomly divided into experimental group and control group,26 cases in each group.Preemptive analgesia drugs were given corresponding, before and 24h after surgery, the serum levels of interleukin-6 (IL-6), tumor necrosis factor-α(TNF-α), venous blood CD4 +T, CD8 +T cells and CD4 +/CD8 + T levels and analgesic effect were detected in all patients.Results After surgery, compared with control group, the serum levels of TNF-αand IL-6 were lower in experimental group (P<0.05); the venous blood CD4 +T cell and CD4 +/CD8 + T levels were higher(P<0.05), CD8 +T cell level was lower in experimental group (P<0.05);the visual analogue scale(VAS) score was significantly lower in 2,4,6,12 and 24h after surgery in experimental group (P<0.05).Conclusions The oxycodone hydrochloride injection preemptive analgesia can significantly inhibit the increase of the serum TNF-αand IL-6 levels, prevent the decrease of immune function, improve the analgesic effect.

In order to investigate the human cytomegalovirus (HCMV) infection, the mouse cytomegalovirus (MCMV) infected mice were experimentally studied. 6 to 8 week old female BALB/C mice with immunosuppression were selected to undergo the MCMV inoculations: intracranial inoculation and peritoneal inoculation. MCMV of the infected mice in various organs and tissues were detected by using beta-gal staining and in situ nucleic acid hybridization assay. The pathological changes were observed in HE staining paraffin-embedded sections. It was found that all the MCMV infected mice showed the retardation of growth and development, and feather looseness. Both intracranial inoculation of 10(4) PFU viruses or peritoneal inoculation of 10(6) PFU viruses resulted in the pathological changes, to some extent, of various organs and tissues in the mice. The pathological changes in liver were consistent with the amount of beta-gal staining positive cells, indicating the liver lesions were mainly caused by viral proliferation. It was also found that the viruses in the immunosuppressed mice subjected to intracranial inoculation could spread to whole body organs, while the viruses in the immunosuppressed mice subjected to intrapeitoneal inoculation couldn't spread to the brain, suggesting blood-brain barrier could prevent the virus from spreading to the brain.
