Obiective To realize real-time data processing in lung ventilation reconstruction based on electrical impedance tomography(EIT). Methods The image reconstruction algorithms, plotting functions and matrix calculations are dynamic transferred with Matlab C++, Mathtools and VC++ to meet the requirements of data processing and imaging in real time.Results Image reconstruction and real-time data processing were realized successfully in lung ventilation based on EIT. Conclusion It provides a new strategy for real-time data processing of image reconstruction by EIT.

Objective Cavernous hemangioma of infant was reported as an obscure diagnosis with the different sensitivity to corticosteroid therapy and various natural courses. Therefore, a clinical studies for the biological classification of deep subcutanious vascular lesions might be needed, which was alluded by Mulliken two decades ago. Methods Infants with cavernous hemangiomas accepted normal system corticosteroid therapy during the first 6 months of life before eight-year-follow-up, which continued until the children were 9 to 10 years old. The expression of PCNA and bFGF, and cellular histological characteristics were observed in 12 cases by biopsy. Results There were two major categories of subcutaneous vascular lesions groups: deep capillary hemangiomas, a lesion regressing slowly, and venous malformation, a lesion growing commensurated with the child. They will be also distinguished on the basis of diverse final treatment results, expression of cellular markers, microscopical characteristics, and physical signs. Conclusion The new classification appears to be helpful to make the choice of therapy for infants with "cavernous hemangiomas" , which is proven to be a terminologic confusion.

Objective To summarize the experience and clinical characteristics in liver re- transplantation following adult-to-adult living donor liver transplantation.Methods Due to biliary complication (2 cases),vascular complication (2 cases),chronic rejection (1 case) and hepatitis recur- rence (1 case),liver re-transplantation was performed on 6 patients through modified piggyback liver transplantation.Vascular anastomosis was performed between the hepatic arteries of donor livers and receptor abdominal aorta in 1 case,and the rest were subjected to end-to-end homonymic vascular anastomosis.Results No operative death occurred.Due to primary non-function,1 died after the ope- ration.During the follow-up period,1 had anastomotic stricture of hepatic artery after the operation and was cured by percutaneous venoplasty.The survival of the rest patients was 12,9,6,4 and 3 months respectively.Conclusion Peritoneal adhesion is the operative difficulty for liver re-transplantation following adult-to-adult living donor liver transplantation.

Trypanosoma is a human parasite severely affecting poor tropical areas.However,current frontline drugs for Trypanosoma treatment have severe side-effects with decreased effectiveness.Based on the fact that aminoacyl-tRNA synthetase is a bonafide drug target for several microorganisms,including bacteria and fungi,it is plausible that it may also be effective target of Trypanosoma.The Trypanosoma brucei leucyl-tRNA synthetase(tbLeuRS)was cloned,expressed and purified to develop an in vitro enzymatic assay system.The assay conditions were further optimized for the effective screening of tbLeuRS inhibitors thus establishing an anti-Trypanosoma drug screening system targeting tbLeuRS.The results indicated that this system can be employed for the effective screening of anti-Trypanosoma drugs with satisfactory specificity.In addition,this system can also be used for compound optimization,as well as IC50 testing.Using this system a series of compounds are identified that are effective Trypanosoma inhibitors without toxicity to human cells.Therefore,targeting tbLeuRS may represent a new venue for the development of anti-Trypanosoma drugs.

The morphological indexes of the Scuophularia ningpoensis seedlings including the longth, diameter and weight were measured, clustering analysis was used to set up the standard quality grading of seedlings of S. Ningpoensis by SPSS. Field experiment was carried out to measure the indicators of plants growth and development, the yield and the quality. The results showed that the growth and yield of class I seedlings were better than those of class II and III. The content of main active ingredients was affected barely by seedlings classification. To ensure the quality, class II seedlings or above should be used for plantation. The established quality classification standard of S. ningpoensis seedlings was scientific and feasible, and provides the basis for the standardized cultivation of S. ningpoensis.

Objective To study the neuroprotective effects of erythropoietin on intracerebral hemorrhage (ICH). Method The rat models of 1CH were produced by injecting autologous blood into caudate necleus by using stereotatic techique. One hundred ten male wistar rats were randomly divided into 4 groups, namely normal group,sham operation group, 1CU group, and EPO treatment group. The immunohistochemistry and TUNEL were used to detect expressions of Bc 1-2 and Bax,and apoptosis cells. LSD- t and Pearson correlation were used to analyzing data. Results The positive cells of TUNEL Bcl-2 and Bax in ICH group and EPO group obviously increased over 6 hours,and reached peak 72 hours later,and decreased over 120 hours,and the positive cells in different intervals significantly decreased in ICH group and EPO group compared with those in sham operation group (P < 0.01). The positive cells of TUNEL and Bax in EPO group in different intervals significantly decreased compared with those in ICH group (P < 0.01). The Bcl-2 positive cells in EPO group in different intervals significantly increased compared with those in ICH group (P < 0.01). The Bax protein expression, Bax/Bcl-2 and apoptosis presented positive correlation (P < 0.01). Conclusions Apoptosis may induce some brain injury after ICH,and EPO can decrease the number of apoptotic cells after ICH by up-regulating Bcl-2 and down-regulating Bax.

From January 2005 to January 2008, 23 cases of fractures and dislocations of cervical spine treated with anterior decompression, reconstruction of bone graft with titanium mesh, and titanium locking plates fixation in Department of Orthopaedics, the 309 Hospital of Chinese PLA were retrospectively analyzed, including 16 males and 7 females, aged 41.9 years (ranging 25 ?65 years). The clinical effect and application value of this treatment was evaluated; the conditions at preoperative, immediate postoperative and follow-up were evaluated by JOA grade, and these radiographs were taken. Lordosis (kyphosis) of the fusion segment with Cobb's angle, and lordosis (kyphosis) of cervical spine with D value were measured to evaluate effect of reconstruction and cervical spine physiological curve. All cases were followed-up for 20.5 months (ranging 1-3 years). Clinical stability was reached in all cases during the follow-up. There were significant differences between preoperative and immediate postoperative, between preoperative and follow-up groups in terms of JOA grade, Cobb's angle and D value (P < 0.05). The JOA grade of immediate postoperative was improved compared with that during follow-up (P < 0.05). The mean improvement rate was 63% at 1 year of follow up. A good curative effect was obtained by using anterior locking plate with titanium mesh systems in treatment of cervical fractures and dislocations and a good effect of restoring and maintaining the lordosis of cervical spine can be also obtained.
