Objective To explore the effect of early tracheal intubation on hypoxemia and level of blood lactate, C-reactive protein(CRP) in patients with severe intracerebral hemorrhage .Methods Fifty-four patients with severe intracerebral hemorrhage were divided into routine tracheal intubation (routine intubation group,n=25) and early tracheal intubation group(early intubation group,n=29) radomly.In routine tracheal intubation group, tracheal intubation was performed only when respiratory failure occurred .In early intubation group , tracheal intubation was performed as long as hypoxemia which can not be fixed by inspiring oxygen , tongue retropulsion or vomit occurred . Levels of artery blood gas analysis , lactate and CRP were tested before and after 2 h ( lactate ) or 24 h ( CRP ) of tracheal intubation .Heart rate and respiratory frequency were also monitored .Results PaO2 , PaCO2 , SaO2 and heart rate were markedly improved after intubation in both groups , levels of lactate and CRP were evidently reduced after intubation in both groups(all P<0.05).After intubation, the PaO2 of early intubation group was significantly higner and the CRP of early intubation group was significantly lower than that of routine intubation group ( all P<0.05);Before intubation, the PaO2 and SaO2 of early intubation group were significantly higher and levels of lactate and CRP were significantly lower than those of routine intubation group ( P<0.05 ) .Conclusion Early tracheal intubation can improve hypoxemia and reduce the level of lactate and CRP in patients with severe intracerebral hemorrhage .

Objective To investigate the biological function of SPA-PEI conjugate(staphylococcal protein A-polyethyleneimine cross-linker),which is one key component for construction of a novel antibody-targeted DNA delivery system.Methods The binding capacity of SPA-PEI conjugate with multiple sources of IgG was determined by enzyme-linked immunosorbent assay and neutralization inhibition assay.The binding capacity of SPA-PEI conjugate with DNA fragment was determined by DNA gel retardation assay,and its DNA condensing ability was measured by Ethidium bromide exclusion assay.Results SPA-PEI conjugate could bind well to many species-derived IgGs.SPA-PEI conjugate had no significant effect on the binding properties of SPA.SPAPEI conjugate could neutralize negative charges of the plasmid DNA or DzTi.Its DNA condensing ability was nearly same to that of free PEI,which suggested a excellent DNA condensing ability of the SPA-PEI conjugate.Conclusion SPA-PEI cross-linkers prepared by this project group maintained the biological activity of SPA and PEI.SPA-PEI cross-linkers could be used for the construction of a novel antibody-targeted non-virus DNA delivery system.

This study was aimed to establish a method for quality control of Tibetan medicine Shi-Wei Xiao-Shi-San (SWXSS). Thin layer chromatography (TLC) was established for the qualitative determination. Cinnamal and piperine were determined by HPLC. The separation was performed on Phenomenex C18 column (4.6 mm × 250 mm, 5μm). The results showed that TLC can be used in the identification of pomegranate seed and Terminalia chebula. The linear ranges of cinnamal and piperine were within the range of 0.06-0.37μg and 0.05-0.33μg, respectively. And the standard line was Y=9.273 2×106X-2.348 2×105, r=0.999 8;Y=7.315×103X-3.857, r=1.000 0. It was concluded that the identification method was specific, accurate and practical, which can be applied in the quality control of SWXSS.

Objective To compare the treatment effect of laparoscopic appendectomy(LA) and open appendectomy (OA). Methods One hundred and forty-five cases of LA performed from May 2003 to May 2005, and 142 cases of OA performed from June 2001 to March 2003 were studied retrospectively. Results There was no difference in operative time between group LA and group OA. In the procedure of LA, some occult disease could be discovered and treated, while OA was not. The administration of analgesic, activity time, incidence of incision infection and hospital stay in group LA were better than those of OA group. While the cost of hospitalization in LA was higher than that of OA. Conclusion LA has significant advantages in treating appendicitis and it should be promoted.

In order to study the excretion of genistein (GEN) capsule, an estrogen drugs, in human, 30 healthy volunteers were selected and orally administered 50, 100, and 300 mg genistein in an parallel study. Genistein were determined in urine by LC-MS/MS and glucuronidated genistein (GENG) were indirectly determined with enzymatic hydrolysis in urine by LC-MS/MS, and the pharmacokinetic parameters were analyzed by DAS software (ver 2.0). The result showed that the concentrations of genistein in human urine were less than 1% of the GENG, and the cumulative excretion of GEN in 48 h were 0.037, 0.134, and 0.142 mg, separately, and the urinary excretion percentage were only 0.07%, 0.13%, and 0.05%, separately. But the cumulative excretion of GENG in 48 h was 5.3, 13.8, and 15.4 mg, separately, and the urinary excretion percentage were 10.6%, 13.8%, and 5.1%, separately, and the max urinary excretive rate was 0.4, 1.0, and 1.4 mg x h(-1), separately (tmax were 6 h). Studies showed that part of drug excreted through kidney in a form of GENG in human, and the cumulative urinary excretion and the maximum excretion rate of GENG showed a proportional increase conditioned with the dose in the range of 50-100 mg, but showed non-linear increase feature in 300 mg.
