Objective To study the effect of leukoreduction transfusion on improving medical quality. Methods The cases in our hospital which had RBC transfusion records in the past 3 years were collected and divided into two groups: leukoreduction group(LR) and non-leukoreduction group(NLR). Through statistical analysis, the items related to leukoreduction were found out and the differences in these items between the two groups were compared. Results Operation complication, non-operation complication, infectious rate, transfusion reactions and mortality rate in LR group were significantly lower than those in NLR group. The transfusion of single components-RBC had less clinical side-effect than the transfusion of complex components including RBC. Conclusions Leukoreduction transfusion can effectively improve clinical therapy and promote the medical quality.

Objective To study the diagnostic value of double-balloon endoscopy (DBE) and capsule endoscopy (CE) for small intestinal bleeding. Methods Overall detection rates of small intestinal bleeding with DBE, CE and the whole alimentary tract barium meal were compared. Positive rates of bleeding detection with DBE and CE were compared within the same patients. Influence of CE on one-procedure rate of DBE was analyzed. Results In 105 cases of small intestine bleeding, DBE detected 24 cases of Crohn's disease, 15 adenocarcinoma, 12 chronic nonspecific inflammation, 10 small intestinal ulcer of unknown reason, 8 entero-mesenchymoma, 8 polypus, 6 vascular deformation hemorrhage, 5 ancylostomiasis, 5 Mechel's diverticula ( including multiple diverticula), 3 lymphoma and 9 of no evident abnormalities. The positive detection rate of DBE is 91.4% (96/105). Disease detection rates of CE and whole alimentary tract barium meal were 75.0% (30/40) and 33.3% (25/75), respectively. The one-procedure rate of DBE is 90% (36/40) based on CE results, but it was only 69. 2% (45/65) according to clinic features and the whole alimentary tract barium meal. Conclusion The main causes of small intestinal bleeding are benign ulcers (including Crohn's disease) and tumor, as well as chronic inflammation. Polyps, vascular deformation, parasitosis, Mechel's diverticulum and lymphoma are the secondary causes.DBE is superior to CE in diagnosis of small intestine bleeding, but CE can increase the one-procedure rate of DBE.

Objective To evaluate the X-ray characterstics of benign and malignant neoplasms on mammography in order to improve their differeatial diagnostic level.Methods X-ray image changes of 67 malignant breast neoplasms were described by the mammography and in comparision with those of 31 benign masses .Results The accordance percentages between the X-ray and histological examinations for the malignant and benigin neoplasms were shown to be 89.6% and 84.0% respectively. Occurrence of masses with an enhanced density , irregular shape, calcification granules in clusters were found to be indication of a malignent lesion.Conclusion The mamography can provide effective imaging data for differential diagnosis betweren the benign and malignant breast neoplasms.

Objective To establish a newborn animal model of renal injury caused by intrauterine asphyxia and explore the mechanism of renal injury in neonate after asphyxia.Methods After two-horn uterus and vessels supplying uterus and ovary were exposed in 21-day-pregnant Wistar rats,arterial clamp occluded one side of vessels.The occluding time were 10 and 30 minutes.Then arterial clamp was taken off,and reperfusion for 30 minutes,2,6,12 and 24 hours respectively.Reaching prescribed time uterus horn was opened rapidly and pups were removed.The pups sacrificed by decapitation.Kidneys were taken out and studied by HE staining and electron microscope.Results Kidney of fetal rats in 21 gestational age was developmental and mature degree of tubules dropped behind that of glomerule.Changes of proximal tubules were early and serious compared with distal tubules during ischemia and reperfusion stages.Conclusion Ischemia and reperfusion to graded pregnant rat can supply an ideal model to study injury of kidney and other organs(intraute)-rously.

Objective To assess the variations in different thyroid stimulating hormone(TSH) and free thyroxine (FT4) detection kits for evaluating thyroid function during pregnancy and to establish the corresponding normal reference ranges.Methods This study was based at the International Peace Maternity and Child Health Hospital affiliated to Shanghai Jiaotong University School of Medicine.A total of 200 pregnant women who visited the hospital between June,2011 and September,2012 were recruited in this study according to the National Academy of Clinical Biochemistry (NACB) criteria.Blood samples were sequentially collected from the women at the first (T1,9-12 weeks),second (T2,16-24 weeks) and third (T3,32-36 weeks) trimesters to determine the serum TSH and FT4 levels using four different detection kits (Siemens-C,Siemens-Ⅰ,Abott and Roche).A linear trend test was used to analyze serum TSH and FT4 levels with four different kits.A percentile range of P2.5 to P97.5 was used to establish the normal trimester-dependent reference ranges of TSH and FT4 levels for different detection kits.The Bootstrap method was used to compare the differences in the four reference ranges.Results Similar dynamic changes in TSH and FT4 levels during pregnancy were detected among the different kits (F=0.950,P=0.595; F=11.640,P=0.081,respectively).Among the four reference ranges of TSH,the Roche kit showed the most remarkable fluctuation during pregnancy,while Roche kit in the first trimester and Siemens C kit in the second and third trimesters showed larger fluctuations in reference ranges of FT4.More importantly,the reference ranges of TSH and FT4 showed significant variations among the four different kits in each trimester (TSH:T1:F=2 945.390,P ＜ 0.01; T2:F=2 826.260,P ＜ 0.01; T3:F=1 698.360,P ＜ 0.01.FT4:Tl:F=1 145.440,P ＜ 0.01; T2:F=2 260.240,P ＜ 0.01; T3:F=1 439.920,P ＜ 0.01).Conclusions TSH and FT4 measurement using four different commercial kits showed similar trimester-dependent dynamic changes.However,it is necessary to establish trimester-dependent and detection kit dependent normal reference ranges of TSH and FT4 for thyroid function evaluation for pregnant women.

Pericellular matrix (PCM) is a narrow tissue region surrounding chondrocytes, which "chondron" with its enclosed cells. A number of studies suggested that PCM is rich in proteoglycans, collagen and fibronectin, and plays an important role in regulating microenvironment of chondrocytes. Direct measures of PCM properties through micropipette aspiration technique showed that PCM was different from mechanical property of chondrocytes and nature extracellular matrix. However, the function of PCM is not clear, and need further study.
