Objective To explore the relationship between MP and HSP.Methods The HSP children treated in our hospital during 2004 to 2006 were tested with MP,and the positive patients were treated with the anti-infectious methods.Results (1)The positive rate of MP was 24.14%.(2)By treating with the anti-infectious methods,all positive patients recovered.All syndrome of the patients disappeared in 3 weeks.The mean time in hospital Was (18.9±3.3)days.Conclusion MP infection Was one of the risk factors tIlat might cauge HSP.

Objective To evaluate the effect of different types of tube feeding on swallowing function of stroke patients. Methods 60 patients with dysphagia post stroke were divided into observation group and control group with 30 cases in each group. The control group received indwelling nasogastric tube feeding, and the observation group received intermittent nasogastric tube feeding. They were assessed with Kubota Water Swallow Test (WST) and VGF on the 1st day and 30th day after admission. Results The scores of drinking test and VGF were better in the observation group than in the control group (P<0.05) on the 30th day. Conclusion Long-term nasogatric tube feeding is effective on dysphagia in stroke patients.

As unrelated allogeneic umbilical cord blood transplantation (UCBT) has been developed for 20 years already since 1988, more than ten thousands cases have cumulatively undergone UCBT over the world. A huge number of clinical data confirmed that UCBT had unique characters with low rate of severe GVHD. The efficacy and data on TRM, relapse and EFS of allogeneic UCBT with HLA 0-1 mismatched are similar to those in HLA matched BMT. UCBT has become the optimal choice for source of hematopoietic stem cells for allogeneic stem cell transplant especially when HLA-matched or haploidentical donors are not available in time. In most developed countries, unrelated allogeneic UCBT developed successively, and in recent years HLA mismatched UCBT with double units performed in adults increased even more rapidly than in children. Another recent trend of UCBT has been extending to treat some non-malignant but refractory diseases in pediatrics, such as severe combined immunodeficiency, thalassemia major, bone marrow failure syndrome and metabolic disorders. The clinical successful practice of double units for cord blood transplantation inspires to ponder over questions remaining mystery. What is the conflict like between two mismatched donor cells in vivo, which does not spoil the whole transplantation but enable the patient to be engrafted successfully without any increment of the dosage by the sum of two doses together? How can they both be taken at the same time firstly by the recipient, but why does only one predominate later? What are the factors enable the donor cells of the winner to sustain? With the references of the international experiences, how to solve the clinical encountered problems, perspective of unrelated allogeneic UCBT and proper strategies to be enacted are reviewed.

ObjectiveTo establish nude mouse tumor models bearing human pancreatic adenocarcinoma SW1990 cells in multiple sites at different time-points and investigate the feasibiilty of multiple tumor-bearing in these models; then the findings and detection rate of 3.0T magnetic resonance image (MRI) in subcutaneous transplanted tumors was analyzed. Methods A total of 6 BALB/C nude mice were randomized into 3 groups (2 mice per group ).At the 1st,8th,15th day,the mice were injected subcutaneously with the suspension of SW1990 cells at left axilla and right axilla and right groin in sequence.Three weeks later,all the bearing-tumor mice were performed with MRI non-contrast enhanced scanning plus Gd-DTPA enhanced scan and the subcutaneous masses were subjected to pathological analysis.ResultsAll the 6 nude mice were alive during the study and obvious mass was observed in every injected site.The tumor size was positively associated with the grwing time.There were 9 tumors which could be de.ted by noncontrast enhanced MRI scanning and one more tumor was detected by contrast enhanced scanning.2 tumors were not detected,the 2 tumors were located at subcutaneous of right groin,with the shortest growing time,and the major axis of the 2 un-detected tumors was less than 5mm.Despite the MRI findings of the transplanted masses similar to that of human pancreatic adenocarcinoma with bleeding,necrosis,they presented the characteristics of a clear rim,with pseudocapeule sign.All the 12 masses were similar with human pancreatic adenocarcinoma under light microscope.ConclusionsIt is feasible to transplant human pancreatic adenocarcinoma cell at three different subcutaneous sites (injected at three different points of time) in the nude mouse,with a minimal survival time of three weeks.However,routine 3.0T MRI cannot detect the early tumors (growing time within 1 week,major axis ＜5 mm).

Objective To investigate the cut-off value of N-terminal portion of pro-brain nairiuretic peptid (NT-proBNP)for detecting various degrees of heart failure(HF)at different ages.Method Totally 48 patients with cardiac dysfunction(NYHA Ⅰ-Ⅳ)were from Department of Emergency Nedicine of Zhongshan Hospital Fudan University.The inclusion criteria inclued:organic heart disease,cardiac dysfunction(NYHA Ⅰ-Ⅳ).The exclusion criteria included:acute coronary syndrome,continuous atrial fibrillation,pulmonary emphysema,lung embolism,chronic renal insufficiency,anaemia,abnormal function of glandula thyreoidea,and tumor.The NT- proBNP was studied in order to find out the relevance of NT-proBNP to the classification of HF among patients aged over75 years old(age≥75 years)and patients aged below 75 years old(age＜75 years).Moreover,the NT- proBNP values were used to differentiate acute cardiogenic dyspnea.The data were expressed as(x±s)and ana- lyzed using analysis of variance and Student's t test with SPSS 11.0.A P value less than 0.05 indicated statistical significance.Results The analysis of NT-proBNP levels showed the leveis of it were associated with the grades of cardiac function and left ventricular ejection fraction(LVEF).NT-proBNP levels in patients aged over 75 years were higher than those in patients aged below 75 years.When patients wele of NYI-IA Ⅱ grade and NYHA Ⅳ grade,the levels of NT-proBNP showed signitieant differences between two sorts of patients(407±277 vs.1358± 967 P＜0.05;3727±1342 vs.9031±2363,P＜0.01).The cut-off value of NT-proBNP determined in 48 patients was at 525 pg/ml(AUC=0.958,sensitivity 100%,specificity 76%),at 1911 pg/ml(sensitivity 73%, specificity 96%)in patients with NYHA Ⅱgrade,which were used to identify severe symptomatic heart failure.The cut-off value of NT-proBNP determined in patients aged over 75 yeats was 849pg/ml(AUC=0.922,sensitivity 100%,s pecificity 57%),at 2990 pg/ml(semitivity 81%,specificity 100%)in patients with NYHA Ⅳ grade.Cobckysions NT-proBNP levels are associated with grades of cardiac functions limit of 75 years.It suggests that higher NT-proBNP value in patients aged over 75 years should be considered to evaluate caidiac function and identify acute cardiac dyspnea.
