Objective To investigate the related factors on survival rate of digital replantation and clinical measures.Methods 27 patients with digital replantation were selected,patients'various aspects relevant factors on the survival rate of digital replantation were analyzed by the single factor analysis and multi-factor Logistic regression.Results 35 fingers were needed to be replanted,the successful rate was 85.7％.There were significant differences in survival rate based on different treatment after injury,different injury reason,use of the vein graft,duration of warm ischemia,whether thrombosis,whether vascular crisis between survival group and non-survival group (x2 =6.386,3.889,4.704,6.176,10.802,4.564,all P ＜ 0.05).The results of multivariate Logistic regression analysis showed that processing method after injury,injury reason,use of the vein graft,warm ischemia time,whether thrombosis,whether vascular crisis were the factors directly affected the survival rate (r =0.902,0.957,0.922,1.825,2.053,1.026,all P ＜ 0.05).Conclusion In order to improve the digital replantation survival rate,patients should be investigated and assessed before digital replantation.The indications should be reasonable selected,factors are compositely considered,preventive measures are taken timely.

The increasingly raised morbidity of hematological malignancies have attracted much attention from scientists and clinicians in recent years, especially the childhood leukemia, It has been demonstrated that extremely low-frequency electromagnetic fields is closely related to pediatric leukemia. The extremely lowfrequency electromagnetic fields might change the size, appearance, quantity, chemical state and energy of cellular biological molecules and induce cascade reaction via effects on cell-to-cell signal transduction, cell proliferation and apoptosis, gene expression and DNA damage, etc, subsequently promote the development of childhood leukemia. This paper overviewed the recent advances of relationship between the extremely lowfrequency electromagnetic fields and childhood leukemia.

AIM: The present study was designed to examine changes in monoamine oxidase (MAO) activity during cerebral ischemia and whether ginkgolide B's brain protection challenges with inhibiting monoamine oxidase. METHODS: The focal thrombotic cerebral ischemia was formed by photochemistry-induced in tree shews .MAO activities in different areas which include ischemic,core, penumbra and contralater and serum, were tested by enzyme color-compared way. The protein contents in different area above was examined by amino acid autoanalytic apparatus. RESULTS: MAO activities in ischemic core in different group were much lower than that in the sham operation group [(15.41?1.63)?10 3 U/g protein] and contralatetral areas [(15.47?1.66)?10 3 U/g protein], with its peak at seventy-two hours after occlusion, but that in penumbra [(25.37?2.01)?10 3 U/g protein] and serum [(210.04?20.67)?10 3U/L] ascended. There were significant differences in MAO activities between ischemic group and control (P

Objective To detect the creatin kinase (CK) and its isozeyme (CK-MB) activity in serum of the healthy black bear (Ursus thibetanus) reared in pens to establish reference standard of biochemistry for CK and CK-MB activities of black bears as well as to offer scientific basis for prevention and cure of the black bear disease. Methods The CK activity and CK-MB activity were measured using spectrophotometer based on the principle of enzymatic reaction rate. All data were used to calculate the mean value, variation coefficient and the confidential interval of expected value of enzymatic activity. Results Under 30 ℃, of the male black bears, the average CK activity is 162.70 U/L, the variation coefficient 11. 90%, the confidential interval of expected value 148.90 to 176.50 U/L, and the average CK-MB activity is 17.4 U/L, the variation coefficient 17%, the confidential interval of expected value 15.26 to 19.54 U/L. Of the female black bears, the average CK activity is 149.3 U/L, the variation coefficient 8%, the confidential interval of expected value 140.68 to 157. 92 U/L, and the average CK-MB active is 15.8 U/L, the variation coefficient 18.6%, the confidential interval of expected value 13.70 to 17.90 U/L. Conclusion The data we obtained can serve as biochemical indexes for the healthy black bears.

Abstract Objective: To construct and express anti-IL-2R? genetically engineering antibody Fab and identify its biological activity.Methods: PCR were used to construct cloning vector 5G1-pA22 of anti-IL-2R? antibody Fab,by digestion of vector 5G1-pA22, anti-IL-2R? an-tibody Fab gene fragment was obtained and then this fragment was coupled with digesting product of pET28b plasmid by EcoRI and HindIII toget a recombinant expression vector 5G1-pET28b, it was highly expressed in the E. coli BL21(DE3) in the form of inclusion bodies, compoing20% of the total protein. After the renaturation of antibody Fab, its binding activity was identified by ELISA and antibody competitive inhibitionassay in vitro. Results: Anti-IL-2R? antibody Fab was successfully constructed and highly expressed in the form of inclusion bodies, its yield wasup to 1 mg/ml.When applied to ELISA, antibody Fab exhibited good spectfic reactivity with rIL-2R, antibody competitive inhibition assay invitro indicated that antibody Fab can compete with IL-2 for binding IL-2R in activated T cell surface.As a result,the activation and proliferationof T cells were inhibited and inhibition percentage exceeded 90%. Conclusion: Had successfully constructed and expressed anti-IL-2R? geneti-cally engineering antibody. Fab,it had good biological ativity.

To study retrospectively on extracorporeal circulation (ECC) in pediatric patients with congenital heart diseases. 1286 cases were divided into two groups. In groupⅠ( n =883) ECC were performed with nonpatterned tubing system, and in group Ⅱ( n =403) patterned tubing system was used. GroupⅠandⅡwere both primed with Ringer′s solastion and colloid. There were no stastistically significant difference in age or body weight between groupⅠand Ⅱ. The crystalloid priming volume in group Ⅱ was less than that in groupⅠ( P

To summarize the experience of application of the cardiopulmonary bypass (CPB) technique in non cardiac surgery in 28 patients, including 22 cases of Budd Chiari syndrome, 2 cases of renal cell carcinoma with cancer cell emboli in the inferior vena cava, 2 cases of tracheal carcinoma, 1 case of intracranial basilar artery aneurysm, and 1 case of leiomyolipoma of the liver with excision and replantation of remaining liver. Different types of CPB were adopted as follows: 10 cases were supplemented by hypothermia and low flow perfusion, 15 cases by deep hypothermia and circulation arrest (DHCA) and 3 cases with vena vena bypass in normothermia, respectively. 2 patients died in early post operative period. It is our opinion that CPB can be used in non cardiac surgery, when it is difficult or almost impossible to carry out with routine surgical technique. The technique can make operations more convenient and safer to perform, even though there are some disadvantages, such as more trauma and higher cost.

Objective To investigate the trend of omtibacterial resistance rate of Acinetobater baumannii in our hospital from Jan.2000 to Jun.2005,and for the guidance of rational use of antibacterials.Methods A.baumannii strain was isolated and tested by K-B method from clinical samples and antibiotic resistance was analyzed and studied retrospectively.Results There was an elevated tendency of the resistance rates to common antibacterial in A baumanii for past six years. The resistance rate to imipenem was the lowest (3.6%) and to amikacin, cefoperazone/sulbactam was 29.5%-77.4%.Conclusion The resistance rates to common the antibacterial in A.baumanii are high and the resistance pattern is wide. It is important to select antibiotics according to the antibiotics sensitivity in vitro.
