Cyclin D is the most closely relationship with tumor ,and it is currently known one of the sub-types of cyclins.CyclinD1,as a positive regulatory factor ,has an important role in the process of cell cycle ,espe-cially in cell proliferation and division .CyclinD1 is unusually up-regulated in lots of human cancers .CyclinD1 is a recently discovered protein which is highly expressed in the urinary tumors ,and its expression in tumors is asso-ciated with a more aggressive phenotype ,prognosis and recurrence .Therefore,the research of the target point to CyclinD1 in the urinary tumors may provide a new method for the therapy to urinary tumors .

Objective To explore the clinical effects of enema combined with massage therapy on jaundice in premature infants.Methods Seventy-five premature infants with jaundice were randomly divided into 3 groups,enema combined message therapy group(group A),abdominal massage therapy group(group B),and double-side phototherapy group(group C).All 3 groups were received the same formula fee-ding,intravenous nutrition and identical drug treatment.Group A was given enema with mixed kaiselu and normal saline together with 60 times clockwise abdominal massage once a day for 2 weeks.Group B only received abdominal massage twice per day for 2 weeks.Transcutaneous bilirubin(TB) indexes of all the premature infants in the 3 groups were detected and transformed into total TB concentrations every morning,through version of MINOLTA JM-102 transcutaneous bilirubin radiometer made in Japan.When TB index counted more than 196.58 ?mol/L,group A and B were given single-side phototherapy for 24 hours.Neither enema nor abdominal massage was given to group C,and double-side phototherapy was applied when TB indexes were above 196.58 ?mol/L.Daily TB indexes,duration of jaundice and phototherapy,time of meconium exhaustion,defecation times in each day,incidence of constipation and feeding intolerance were recorded.Results Duration of jaunhospitalized and phototherapy were significantly shortened in group A compared with those of the other groups.In 34 premature infants who were hospital for at least 2 weeks,TB indexes in group C were lower than those in group B on the 9th day.On the 12th day and the 14th day,TB indexes in group A and C were lower than those in group B(Pa

Objective To study the construction of tissue engineering fat filler and the survival of fat particles.Methods Stromal vascular fraction (SVF) was derived from inguinal subcutaneous fat of rabbits,mixed with autologus mature fat particles and with or without neuropeptide Y to construct PLGA composite tissue.The complex was subcutaneously transplantef into back sites of the rabbits.Based on the different combination five groups were divided:Group A:PLGA + mature fat particles without NPY;Group B:PLGA + mature fat particles + NPY;Group C:PLGA + complex of SVF with mature fat particles without NPY;Group D:PLGA + complex of SVF with mature fat particles + NPY;Group E:Complex of SVF with mature fat particles + small ball with NPY.Diffenrence of virous constructive ways and fat particle survival was evaluated by general observation,histological staining,fluorescence tracing at two weeks,one month and three month after operation.Results Group D was superior to groups A,B,C and E in survival volume,graft texture and vascularization at one mouth and three mouths.The fat average srvival rate was 57.5±2.5%.Fat cell grew well,and precursor cells proliferated and differentiated actively.Conclusions High quality tissue engineering materials are successfully established with SVF-mature fat particle complex,PLGA and NPY,which could obviously improve fat particle transplantation.

Objective To develop a rapid and reliable polymerase chain reaction (PCR) procedure to detect the pathogenic fungi in clinical specimens. Methods Skin, nail and hair samples were taken from patients suspected of being infected with superficial mycosis. Pathogens were detected by PCR based on the ITS1 primer, and the results were compared with those from microscopic examination and culture. Results One hundred and twelve patients were recruited in this study. For PCR, microscopic examination and culture the sensitivities were 80.7%, 96.5% and 70.2%, the specificities were 100%, 89.1% and 100%, the positive predictive values were 100%, 90.2% and 100%, and the negative predictive values were 83.3%, 96.1% and 76.4%, respectively. The PCR process could be completed within 24 h. Conclusions PCR assay has good specificity and accuracy, while fungal culture takes 2 weeks to get the results. PCR is helpful for making rapid clinical diagnosis, which leads to the appropriate treatment of superficial fungal infection.
