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.

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.

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.

Objective To observe the effects of acupuncture on oxidative stress and neuronal damage in the prefrontal cortex of chronic cerebral hypoperfusion (CCH) rats; To investigate the molecular mechanisms of acupuncture in cognitive impairment of vascular dementia (VD) rats. Methods The animal model of VD was replicated by permanent bilateral common carotid artery occlusion (2VO) to induce CCH in rats. After modeling, rats were randomized into model group, acupuncture group and non-acupoint group. Sham-operation group was set as control group. Rats of acupuncture group and non-acupoint group were treated with needling for 2 weeks at 3 days after 2VO. Nissl and DHE staining were respectively used to evaluate the numbers of neurons and ROS level. SOD activity was examined by xanthine oxidase technique. Results Compared with sham-operation group, the number of neurons and SOD activity decreased in the model group, while the ROS level increased. Compared with the model group, the number of neurons and SOD activity increased in the acupuncture group, while the ROS level decreased. There were no obvious changes in all indexes in non-acupoint group. Conclusion Acupuncture can inhibit oxidative stress and improve neuronal damage and loss in the prefrontal cortex of VD rats.
