Objective To discover the basic principle of hospital operation and predict the hospital developing trends through analysis of massive data involved in the hospital information system(HIS),with a view of providing better services to patients.Methods The Oracle Warehouse Builder was used as technical platform of date warehouse building in the process of modeling the HIS by using relational database and modeling the data warehouse by using the star model of the multi-dimensional database models.Data Miner,a data mining tool,is also applied to analyze information in the hospital related to inpatient structure and mobility,expenses structure,medical workload and economic benefits.Results Support was provided to management and decision making in hospital.Conclusion Wide applications of data warehousing and data mining are observed in HIS,resulting in remarkable economic and management benefits.

Esophageal cancer is one of the tumors with high morbidity rates in China, and surgery remains to be the preferred treatment. However, certain complications such as anastomotic fistula, lung infection, respiratory failure, and circulatory failure occur after surgery. Postoperative enteral nutritional support could not only maintain and improve the nutritional status of the body but also re-duce complications and maintain normal immune function. This review focuses on the progress in postoperative enteral nutrition in pa-tients with esophageal cancer.

The pathogenesis of post- infectious irritable bowel syndrome(PI-IBS)involves abnormal intestinal immune barrier, which possibly includes the pathological aspects: Intestinal and systemic changes in T lymphocyte; the change of inflammatory cytokines; a increase in intestinal mast cells and enterochromaffin cells and so on. Treatment by western medicine based largely on symptomatic treatment. TCM thinks that the fundamental organ of the irritable bowel syndrome is the liver. Emotional factors inducing liver dysfunction lead to the symptoms of irritable bowel syndrome. The pathogenesis of IBS is, the disorder of movement of qi in liver and spleen. Stagnation of liver-QI with deficiency of the spleen or disharmony between liver and spleen is the key pathogenesis of post-infectious irritable bowel syndrome. On this basis, in various stages of the disease, there may be a different pathogenesis. As a special type of IBS, the balance of vital qi and evil factors determine the disease progression of PI-IBS, in the treatment course also should not forget dispelling pathogenic factors while strengthening body resistance, tonifying deficiency and removing dampness。

The capsule endoscope swallowed from the mouth into the digestive system can capture the images of important gastrointestinal tract regions. It can compensate for the blind spot of traditional endoscopic techniques. It enables inspection of the digestive system without discomfort or need for sedation. However, currently available clinical capsule endoscope has some limitations such as the diagnostic information being not able to correspond to the orientation in the body, since the doctor is unable to control the capsule motion and orientation. To solve the problem, it is significant to track the position and orientation of the capsule in the human body. This study presents an AC excitation wireless tracking method in the capsule endoscope, and the sensor embedded in the capsule can measure the magnetic field generated by excitation coil. And then the position and orientation of the capsule can be obtained by solving a magnetic field inverse problem. Since the magnetic field decays with distance dramatically, the dynamic range of the received signal spans three orders of magnitude, we designed an adjustable alternating magnetic field generating device. The device can adjust the strength of the alternating magnetic field automatically through the feedback signal from the sensor. The prototype experiment showed that the adjustable magnetic field generating device was feasible. It could realize the automatic adjustment of the magnetic field strength successfully, and improve the tracking accuracy.
