Objective To investigate the risk factors of pulmonary fungal infection in intensive care unit(ICU),and discuss the strategy of prevention and treatment.Methods Forty children with pulmonary fungal infection in ICU of Wuhan Children's Hospital from Jan.2003 to Jan.2007 were analyzed retrospectively,including primarily diseases,application of antibiotics,adrenal cortical hormone and virulence operation,therapy and turnover.Results All children were accepted the therapies of broad spectrum antibiotics and glucocorticoids for long time before definite diagnosis of pulmonary fungal infection.Seventy-five percent children were received invasive operations or therapies.Their average time of stayed in hospital was 37.8 d.The clinical symptoms and imaging examinations were untypical.Blastomyces albicans was the main pathogen.After the antifungal agents and supportive treatment used in time,35 cases(87.5%) were cured and 5 cases(12.5%) died.Conclusions The major risk factors of children pulmonary fungal infection are long-time use of broad spectrum antibiotics and glucocorticoids.The pulmonary fungal infection can decrease by rational use of broad spectrum antibiotics and glucocorticoids,decreasing the unnecessary invasive operations,strengthening the supportive therapies of micro-ecosystem,and applying the antifungal agents in time.

0.05).But after the treatment,there were significant increases in pa(O2),SaO2 and PCIS(Pa0.05).Conclusions Early application of hyperoxia liquid could decrease multiple organ anoxia and the damage of lipid peroxidation.It has obviously protective effects on multiple organ damage during ischemic reperfusion in infants with muggy syndrome.

Tumorous cells are characterized by distinctive metabolic reprogramming and living conditions. Understanding drug metabolizing features in tumor cells will not only favor the estimation of metabolic rate, elimination half life and the assessment of potency, but also facilitate the optimal design of anti-tumor drugs/prodrugs. This article reviewed the expression and activity features of major drug metabolizing enzymes (DMEs) in solid tumorous tissues, such as liver, intestine, breast and lung, and the difference from the correspondingly normal tissues, exemplified by the metabolic properties of some classic antitumor-agents in tumorous tissues. In combination with the data retrieved in vitro tumor cell lines, we discussed the similarities and differences of DMEs expression and function between tumor tissues (in vivo) and tumor cells (in vitro), and proposed the possible factors that cause the differences.

Poly(ADP-ribose)polymerase-1 (PARP-1) plays a significant role in the DNA repair process by catalyzing the transfer of ADP-ribose from NAD+ to its receptors. It is a promising anticancer drug target and many PARP-1 inhibitors have been developed and used in the clinical trial. In this work, a series of 3-(2-oxo-2-substituted acetamido)benzamides have been synthesized and their inhibitory activities against PARP-1 were evaluated. Of all the tested compounds, six compounds displayed inhibitory activities with IC50 values ranging from 0.23 to 5.78 µmol.L-1 . The binding pose of compound 5a was predicted using molecular docking to facilitate further structural modification.

To study the interaction of drugs of different properties, namely puerarin, borneol and catalpol in the process of in- clusion, in order to explore the inclusion regularity of multi-component and multi-property traditional Chinese medicine compound in- clusions. With HP-β-CD as the inclusion material, the freeze-drying method was used to prepare the inclusion. The inclusion between puerarin, borneol and catalpol was tested by measuring the inclusion concentration, DSC and X-ray diffraction. According to the find- ings, when insoluble drugs puerarin and borneol were included simultaneously, and puerarin was overdosed, puerarin included was almost equal to puerarin included, and borneol was not included. When puerarin was under-dosed, and HP-β-CD was overdosed, borne- ol was included, and the simultaneous inclusion was lower than the separate inclusion of borneol. When water-soluble drug catalpol was jointly included with puerarin or borneol, the simultaneous inclusion was almost the same with their separate inclusion, without charac- teristic peak of catalpol in DSC and X-ray diffraction patterns. There is a competition in the simultaneous inclusion between water-solu- ble drugs puerarin and borneol and a stronger competition in puerarin. The water-soluble drug catalpol could be included with HP-β-CD with no impact on the inclusion of puerarin or borneol.

0.05),but the expression in controls were negative.The expression levels of PRAME gene at remission was decreased obviously,but increased again when the patients relapsed.Conclusions Expression of PRAME gene has a high level in childhood acute leukemia.The dynamic changes are closely related with the prognosis.It can be regarded as a candidate for detecting minimal residual disease in acute leukemia,and may have important implications for estimating the prognosis and guiding the chemical therapy.
