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.

Objective To rational design HCV DNA vaccine candidates and evaluate their specific immunity to HCV in mice. Methods We design to construct two DNA vaccine candidates, one consists of E_2 (the envelope glycoprotein 2 of HCV) gene only, the second consists of E_2-gAD (Globular Domain of Human Adiponectin) fusion gene via overlapping PCR. Confirm the expression of the DNA vaccines by Western blotting, and then vaccinated by injection of DNA vaccines with gene electrotransfer (GET) in BALB/c mice. The immune response was measured by IFN-gamma ELISPOT. Results The DNA vaccine candidate consists of E_2-gAD could effectively express in vitro , and it could induced a higher anti-HCV T cell response in mice than the one consists of E_2 only. Conclusion The HCV DNA vaccine consists of E_2-gAD fusion can increase the immunity of the E_2 to some extend, and the research paved a way to develop and optimize the novel HCV DNA vaccine.

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.

Objective To evaluate the effectiveness of arthroscope-assisted surgical technique in treating knee fractures and knee peripheral fractures.Methods From September 2000 to December 2005,there were 46 cases with knee or knee peripheral fractures,in whom artbroseope-assisted surgical technique was performed in 36 cases including 24 males and 12 females,with mean age of 30.5 years (18-52 years).Of 36 cases,26 cases with patella fractures were treated by internal fixation of tension band using cancellous bone screws,four with distal end femoral fractures by retrograde interlocking using intramedullary nail and six with fractures of tibial plateau and tibial condyle crista by internal fixation u- sing cancellous bone screws.Results The mean hospitalization was eight days.A follow up for 3-36 months(average 14 months)in 36 cases showed fracture healing.Of 36 cases,32 cases regained full knee range of motion,four left with terminal flexion,with mean loss of 15?,and had thigh circumference (10 cm above knee)1.1 cm(range 0.6-2.0 cm)shorter than health side and two had slight pain in the knee joint.Lysholm knee joint function score was 86.5+7.6 for patellar fractures,tibial plateau frac- tures and condylar crista fractures.Conclusion As for knee or knee peripheral fractures,arthroscope- assisted surgical technique can provide fine monitoring,decrease trauma and complications,fixate inter- nally and help early ground exercise.
