In order to scientifically and efficiently make use of the limited medical resources and gradually resolve the problem that "medical treatment is difficult and expensive",large-scale hospitals in the western region must reduce medical cost in purchasing,using and cost of medical consumables.This paper discusses the role of strengthening the management of medical consumables,and studies how to standardize the management process for medical consumables in large-scale hospitals in western region.

Objective: To explore the application value of real-time adenosine stress 3-dimensional echocardiography (3D-ASE) for diagnosing the patients with of coronary artery disease (CAD).
Methods: A total of 46 suspicious CAD patients were studied by 3D-ASE analysis. There were 26 male and 20 female patients from (38-73) years of age at the mean of (63.3 ± 7.2) years. Adenosine stress echocardiography was performed by infusing the agent at 140 ug/(kg?min) in 6 minutes. The changes of segmental ventricular wall motion, electrocardiogram (ECG), clinical symptoms, blood pressure and heart rate were recorded. Positive 3D-ASE result was deifned by the time of left ventricular segment minimum contraction volume gradually extending. Coronary angiograph (CAG) was conducted at 2 weeks after 3D-ASE, positive CAG ifnding was conifrmed by at least one of three main branches with the stenosis≥50%.
Results: There were 29/46 patients with positive CAG findings, 26 with positive 3D-ASE presentations and 8 with positive adenosines tress ECG. CAG showed that 48 coronary branches were positive and 90 were negative;3D-ASE indicated that 40 coronary branches were positive and 98 were negative. For 3D-ASE diagnosed coronary lesions, the overall sensitivity was 89.6%(26/29), speciifcity 76.5%(13/17), accuracy 84.8%(39/46). There were 36 branch lesions conifrmed by both CAG and 3D-ASE. For 3D-ASE determined coronary lesions, the sensitivity was 75%(36/48), speciifcity 95.6%(86/90), accuracy 88.4%(122/138). For 3D-ASE found single, double and three vessels diseases, the sensitivities were 60%(9/15), 88.9%(8/9) and 100%(5/5) respectively. The e occurrence rate of 3D-ASE side effect was 52.2%, there were usually slight symptoms without severe adverse reaction.
Conclusion: 3D-ASE has the high sensitivity and speciifcity in CAD diagnosis, it is an non-invasive examination with slight side effect, and therefore, has an important application value in clinical practice.

Pancreatic cancer is one of the most malignant tumors with a high mortality rate attributed to its widespread metastasis.A number of cellular signal transduction pathways involved in multiple genes play an important role in regulating this complex metastatic cascade of pancreatic cancer.NF-kappa B is one of the crucial signaling pathways.Studies has indicated that NF-kappa B could modulate a series of biological events relevant to tumor progress by controlling multiple targeted genes expression,such as cell proliferation,anti-apoptosis,angiogenesis,epithelial-mesenchymal transition,inflammation,stress response,etc.Furthermore,it can also up-regulate Hedgehog and MMPs signaling pathways.To help us better understand the potential mechanism and identify more sensitive tumor markers and selective targets,this review will underline the significant roles of NF-kappa B signaling pathway in regulatory network of pancreatic cancer metastasis.

Objective To explore the curative effect of triple lumen feeding tube on upper gastroin-testinal tract perforation after endoscopic operation.Methods A total of 1 12 patients with upper gastrointes-tinal perforation after endoscopic operation were involved in this prospective control test.The remission rate of abdominal pain and abdominal distension,gastric pH,lesion healing time,length of stay and the success rate of conservative treatment were compared between the control group (indwelling traditional gastric tube and intravenous use of omeprazole injection)and the experimental group (intestinal administration of PPI through triple lumen feeding tube).Results The remission rate of abdominal pain of the experimental group was 61. 3% at 6 hours,and 83. 2% at 12 h,which were significantly higher than those of the control group (P<0. 05 ).The lesion healing time(of cases where lesions were not clipped)and length of hospitalization of the experimental group were significantly shorter than those of the control group(P<0. 05 ).The gastric pH and success rate of conservative treatment of the two groups had no significant difference(P>0. 05 ).Con-clusion The curative effect of triple lumen feeding tube on upper gastrointestinal tract perforation after endo-scopic operation is ideal.
