ObjectiveTo study the correlation between contrast-enhanced ultrasound (CEUS) features and Nottingham prognostic index (NPI) in patients with breast carcinoma. Methods The ultrasound features and microvascular imaging manifestation of 91 breast carcinomas confirmed by pathology were retrospectively analyzed.NPI was typically stratified into 3 major groups:NPI ＜ 3.4 ( n =19 ), NPI:3.4-5.4 ( n =52 ) and NPI ＞5.4(n =21 ). Results With the increase of NPI, the rate of heterogeneous enhancement, perfusion defects, edge enhancement higher than center enhancement, and unclear border increased.The difference among the 3 groups had statistical significance (P ＜ 0.05 ).There was no significant difference in enhancement order among the 3 groups ( P ＞ 0.05 ).The lesions of the 3 groups were mainly “high enhancement” and there was no significant difference among the 3 groups ( P ＞ 0.05 ).With the increase of NPI, the rate of early enhancement and late regression increased.The difference among the 3 groups had statistical significance ( P ＜ 0.05 ).With the increase of NPI, the rate of enlarged and twisted vessels as well as peripheral vessel burr increased.There was significant difference among the 3 groups ( P ＜ 0.05 ).ConclusionCEUS festures and microvescular architecture pattern of breast carcinoma are related to NPI, which is useful in predicating the prognosis of breast carcinoma.

BACKGROUND: Rats model of kidney transplantation are common used in the research of organ transplantation and kidney associated diseases. However,the existed modeling methods have various problems in transplanting time or transplantation effect. OBJECTIVE: To establish a lateral kidney transplantation model with simplity,safty,and high success rate. DESIGN,TIME AND SETTING: The analysis experiment of animal model was performed at the Department of Urology,Fudan University between March and June,2008. MATERIALS: 60 Wistar rats and 60 Sprague Dawley rats were selected as donors and recipients,respectively. METHODS: The left kidney graft was transplanted heterotopically into the left infrarenal position,to perform donor abdominal aorta and left renal vein end-to-side anastomoses to the recipient abdominal aorta and inferior vena cava. The ureter of kidney allograft was inserted into bladder traced by 5-0 needle. Bilateral native kidneys nephrectomy of the recipient was performed immediately. The operation time and survival rate were measured. MAIN OUTCOME MEASURES: Transplanting time,warm ischemia time,cold ischemia time,arteriovenous anastomosis and operation time,graft failure rate and reason,survival rates. RESULTS: The operation cost 100-140 minutes. The warm ischemia time was about 8-10 seconds,while the cold ischemia time was 40-60 minutes. Operation achievement ratio is 85%. Reasons of failures were analysed as follows: stenosis of the anastomotic stoma and thrombosis (6.67%),hemorrhage of the anastomotic stoma (5%),infection (1.67%),and unknown reason (1.67%). CONCLUSION: The establish method with advantages of convenience and reliability,which can notably shortened time of warm ischemia of the graft and urinary tract reconstruction and decreased complications.

ObjectiveTo study the characteristic findings on MRI in children surviving premature delivery with cerebral palsy.MethodsThe clinical data and MR imaging in 16 cases surviving premature delivery with cerebral palsy was retrospectively analyzed, compared with 16 healthy and age-matched controls.Results16 cases were final diagnosed as cerebral palsy with spstic diplegia. MRI features of children surviving premature delivery with cerebral palsy included abnormally high signal intensity in the periventricula white matter on T2WI, marked loss of periventricular deep white matter, ventriculomegaly with or without irregular ventricular outline and atrophy of the corpus callossum. These features were consistent with periventricular leukomalacia(PVL).ConclusionPVL was the characteristic findings on MRI in children surviving premature delivery with cerebral palsy. The characteristic findings of PVL was useful in determining the etiology and type of cerebral palsy in children.

Objectives To investigate the correlation between single nucleotide polymorphisms (SNP) in interleu-kin-15 (IL-15) and treatment response in childhood acute lymphoblastic leukemia (ALL). Methods Genomic DNA samples extracted from remission bone marrow cells of ALL patients were genotyped by MassArray. Five SNPs (rs10519612, rs10519613, rs17007695, rs17015014 and rs35964658) in IL-15 and their association to minimal residual disease (MRD) status in the end of induction therapy were studied. Results SNP rs17007695 was associated with the early response in children with ALL(P=0.049) and the incidence of positive MRD after induction therapy in CC genotype carriers was 1.8 times more than that in TT genotype carriers. Haplotype analysis of these five SNPs showed that the frequency of haplotype CACGG in MRD positive group was 2.1 times higher than that in MRD negative group (P=0.035). Conclusions IL-15 gene polymorphism was associated with the early treatment response in Han Chinese children with acute lymphoblastic leuke-mia.

AIM:Atherosclerosis primarily involved systemic arteries .Luminal surface , a monolayer of endothelial cells , of artery directly exposes to blood and is susceptible to active substances in the blood .Exosomes contain significantly amount of proteins and RNAs .Ex-osomes can be good and bad for cells , depending on their component .Thus, exosomes may contribute to atherosclerosis by affecting endothelial cells .This study analyzed the relationship of exosome proteins and atherosclerosis .METHODS: Fifty-six patients and healthy subjects were recruited and divided into two comparisons:healthy subjects vs atherosclerosis ( HS vs AS) , and hypertension vs hypertension plus atherosclerosis ( HT vs HT+AS) .Serum exosomes were decoded by protein mass spectrometry .The protein profile and function were analyzed by gene ontology ( GO) .RESULTS:It was found that five child terms repeatedly appeared in “response to stimulus” and “immune system process” of BP of the two categories ( HS vs AS and AS vs HT+AS):“positive regulation of innate immune response”,“immune response-activating signal transduction”,”activation of innate immune response”,“innate immune re-sponse-activating signal transduction” and “innate immune response activating cell surface receptor signaling pathway ”.Two child terms repeatedly showed in “binding” of MF of the two categories:“antigen binding” and “enzyme binding”.Two proteins, PSMA6 and PSMA7, were repeatedly shown in the two categories .CONCLUSION:GO analysis was utilized for structure hierarchy “tree” to illustrate these proteins involved in various terms in BP , CC and MF.The PPI analysis supplied proteins which may play potentially im-portant roles in AS process .Innate immune system and blood coagulation pathway contribute to AS formation .The proteins, PSMA6, PSMA7 and Annexin A2, may can be the new target proteins for prevention and treatment of AS .
