Micrometastasis is an independable prognostic factor for the cancer patients.Furthermore,free-disease survival and overall survival of the cancer patients are correlated with micrometastasis.In addition, detection of micrometastasis can be used to monitor the efficacy of adjuvant therapy,predict outcome and im.prove the stage of patients with carcinoma.Micrometastasis has great significance for clinical comprehensivetreatment.The limitations of this study include the lackness of retrospective analysis,the small number of pa-tients studied,and the short follow-up time for the cancer patients.

Medical equipments are essential supplies to carry out medical work. How to ensure the safety and reliability of the medical equipments in diagnosis, and reduce procurement and maintenance costs is a topic of concern to everyone. In this paper, product lifecycle management (PLM) and enterprise resource planning (ERP) are cited to establish a lifecycle management information system. Through integrative and analysis of the various stages of the relevant data in life-cycle, it can ensure safety and reliability of medical equipments in the operation and provide the convincing data for meticulous management.

Medical consumables material is essential supplies to carry out medical work, which has a wide range of varieties and a large amount of usage. How to manage it feasibly and efficiently that has been a topic of concern to everyone. This article discussed about how to design a medical consumable material management information system that has a set of standardized processes, bring together medical supplies administrator, suppliers and clinical departments. Advanced management mode, enterprise resource planning (ERP) applied to the whole system design process.

Objective To investigate the effects of sevoflurane on the systemic inflammatory response and cardiopulmonary function in septic shock rats. Methods Thirty-two SD rats, 8-10 months old, weighing 250-300 g, were randomly divided into 4 groups (n = 8 each): sham operation group (group S), cecal ligation and puncture (CLP) induced septic shock group (group CLP) , sevoflurane I group (group SEV, ) and sevoflurane II group (group SEV,). The abdomen was opened but CLP was not performed in group S. The septic shock was induced by CLP as described by Baker et al. Group SEV, and SEV, inhaled 2.4% sevoflurane for 30 min at 1 h and 3 h after the successful establishment of the model respectively. At 1, 3 and 5 h after septic shock, MAP and HR were recorded and arterial blood samples were taken for blood gas analysis and determination of plasma concentrations of TNF-α, IL-1, MDA and NO. The left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVESD), left ventricular fractional shortening (LVFS) and cardiac output (CO) were also detected 5 h after septic shock. The animals were killed after the detection of cardiac function. The lungs were removed for determination of W/D lung weight ratio and Evans blue (EB) content. The tissues from the heart, lung, liver and kidney were taken for detection of NF-kB activity by electrophoretic mobility shift assay (EMSA) ResultsMAP was significantly lower, HR higher, LVEDD, LVESD, LVFS, CO, pH value, PaO2 and PaCO2 lower, and W/D lung weight ratio, EB content, plasma concentrations of TNF-α, IL-1, MDA and NO, and NF-kB activity in the heart, lung, liver and kidney tissues higher in group CLP, SEV, and SEV2 than in group S (P < 0.05). NF-kB activity in the heart, lung, liver and kidney tissues and plasma concentrations of TNF-α, IL-1, MDA and NO were significantly lower in group SEV, than in group CLP and SEV2 ( P < 0.05 ), but no significant differences were found in the other indices between group SEV, and CLP and between group SEV1 and SEV2 ( P > 0.05). Conclusion Inhalation of 2.4% sevoflurane for 30 min 1 h after septic shock can inhibit the systemic inflammatory response slightly, but can not improve the cardiopulmonary function in rats with CLP-induced septic shock.

Objective To study the effect of endoscopic treatment in acute severe pancreafitis. Methods EST(endoscopic sphincterepapiilotomy) and ENBD ( endoscopic naso-billary dralnage) or ENPD ( endoscopic naso-pancreatic drainage) were used to treat the acute severe pancreatitis(ASP). Results The recover time of blood dia-stase of the endoscopic therapy group and the contrast group was (3.2±1.5) days, (6.6±1.2) days, respectively (P<0.01) ; the incidence of needing to be operated was 0.7% (1/140), 6.5% (8/124), respectively (P<0.05) ;mortality rate was 0:7% (1/140) ,7. 3% (9/124) ,respectively(P <0. 01 ) ;the incidence of complication was 3.6% (5/140) ,41.9% (52/124), respecfivly(P<0.01). Conclusion EST + ENBD(or ENPD) in treating ASP has cer-tain effect and is the primary therapy to the ASP.

Cardiovascular disease is a frequently-occurring disease of human society, each year many patients in need of vascular graft surgery. The emergency and application of tissue engineered blood vessels, in particular the application of nanomaterials, will hopefully solve the problem of vascular sources. Here this article reviews the research contents and performance evaluation of tissue engineered blood vessels.

The reoperation for biliary diseases is usually unplanned, and the major reasons leading to this situation include:(1) The initial operation was performed under emergency situation and radical procedure could not be carried out.(2) The surgical procedure was inadequate.( 3 ) The operator was unqualified for the operation. In order to avoid repeated operations,the following principles must be obeyed strictly.Firstly,once the initial operation was failed,the patients must be transferred to large medical center and the reoperation must be performed by hepatobiliary specialists.Secondly,the operator must realize that most of the patients were in poor condition because of the previous operation,and they needed careful evaluation of organ function and adequate supportive treatment before reoperation.Thirdly,various measures must be taken to avoid unplanned operation and ensure the successful implement of radical operation at a time:( 1 ) Operator must learn all the details of previous operation,which include operation procedure,findings during operation and postoperative complications.( 2 ) Cholangiogram of the whole biliary tree is important for surgical planning,ultrasonography,computed tomography (CT),endoscopic retrograde cholangiopancreatography,magnetic resonance cholangiopancreatography, percutaneous transhepatic cholangiography (PTC),or PTC-CT should be performed solely or comprehensively to determine the nature and location of lesions.For bile duct injury,additional examination including CT angiography,magnetic resonance angiography or digital subtraction angiography is necessary to ascertain the accompanied vessel injury.(3) Making individual surgical procedure according to patien's condition and distribution of lesions.

Corydalis yanhusuo W. T. Wang ex Z. Y. Su et C. Y. Wu is an aperennial herb which grous wild in Anhui Province. The tuber of the plants is used as an anodyne. Cultivation of the plant with seeds obtained from the wild was carried out in our nursery breeding house. Results showed that the emergence rate depends upon the size and ripeness of the seed. Although it is a dicotyledon,yet its seedling showed only a single cotyledon. Secretary tissues could be found in its cuticular layer. Cambium was well developed but both xylem and phleom were not well developed

Objective To investigate the therapeutic effect of transplantation of limbal epithelial cells and decellularized porcine cornea construct in rabbits with corneal alkali burn.Methods Allogeneic rabbit limbal epithelial cells were cultured and identified.Porcine cornea scaffold was fabricated by decellularization.The LECs-DPC construct was cultured and transplanted to the alkali-burned corneal surface of rabbits(4month follow-up).Results Immunocytochemistry and RT-PCR analyses revealed the presence of ABCG2 positive limbal stem cells.A general view showed the corneas were clear and vessel-free postoperatively.HE and Masson Trichrome staining results indicated the epithelial stratification,fewer cellular infiltration,DPC' integration into host corneal tissues,and more regular collagen configuration.Transmission electron microscopy exhibited formation of desmosomes and microvilli.Conclusion Allogeneic limbal epithelial cells transplantation using DPC as a carrier can restore corneal clarity after alkali burn in a rabbit model.
