Cardiopulmonary bypass(CPB) is often followed by pulmonary dysfunction,and is also regarded as a high risk factor for development of acute respiratory distress syndrome(ARDS).This article reviewed the recent researches of the mechanisms of lung injury induced by CPB.

Cardiopulmonary bypass(CPB) can induce systemic inflammatory response syndrome(SIRS).This review elaborated the influences of SIRS in acute lung injury after CPB.

The college students innovative test project,which advocates student-centered teaching pattern focusing on questions and subjects is an important component of the project on undergraduate teaching quality and teaching reform in medical college of Shanghai Jiao Tong university.The innovative test project has effectively fostered the innovative spirits,practical abilities,scientific attitudes and learning initiatives of the college students after being implementing for more than four years.Besides,it has changed the teaching philosophy of teachers and created a favorable atmosphere of innovative practice.Several problems have emerged during the implementation of the project including broad topics,limited sample size and incorrect motives for doing tests.Exclusive mechanism aiming at the long-term effect of the project should be established, the concept of the project should be promoted and the communication platform should be built in order to consummate this project.

Objective To investigate the expression of CD14, the receptor of lipopolysaccharide (LPS) on Kupffer cell membrane during the course of CCl4-induced liver injury and its role in activation of Kupffer cells. Methods The experimental rats were hypodermically administered CCl4 twice weekly for up to 8 weeks. Kupffer cells were isolated from the liver of normal and CCl4-treated rats by the combined ‘collagenase-pronase’ perfusion method and discontinuous density gradient centrifugation. On the following day after isolation, the cells were incubated with RPMI-1640 containing various doses of LPS for 6 h. The tumor necrosis factor (TNF-?) in the supernatants was measured by ELISA. The expression of CD14 mRNA on Kupffer cells was determined by RT-PCR. The plasma levels of endotoxin were determined by chromogenic substrate limulus amebocyte lysate assay. Results Baseline TNF-? production of Kupffer cells isolated from CCl4-treated rats in 4 and 6 weeks was significantly higher than that of controls (P

OBJECTIVE:To investigate the influence of TCM Granules of the detoxification and dissipation blood stasis formula Ⅱon fulminant hepatic mitochondrial lipid peroxidation in rats with hepatic failure.METHODS:The fulminant hepatic failure rat models were established by subcutaneous injection of thioacetamide (TAA).48 Wistar rats were randomly divided into 7 groups:blank control group,model group,low dose group,medium dose group,high dose group,the lactulose treatment group,and the "Bezoar pill for resurrection" treatment group.Intragastric administration was executed 3 d before model-making,twice per day with the interval of 12 hours.They were administered for 11times.12 hours after model establishment.MDA、SOD、CAT、GSH、NO and liver necrosis area in hepatic mitochondria were determined.RESULTS:The detoxification and dissipation blood stasis formula Ⅱcould notably reduce liver necrosis area and restrain produce of hepatic mitochondrial lipid peroxidatide MDA,retrieve the activity of SOD、CAT and increase the content of GSH,NO.Moreover it shows dose-effect relation.Compared with model group,there is statistical significance(P

ObjectiveTo observe the relationship between astrocytes and neurons in rat's medulla oblongata after exposed to 8Hz, 90dB/130dB infrasound for different times. MethodsRats were exposed to 8Hz, 90dB/130dB infrasound for 2 hours per day.At the 1st,7th,12th,21th and 28th day, the expression of glial fibrillary acidic protein (GFAP) and Fos in medulla oblongata were detected using double-labling immunohistochemical method.Results GFAP-positive astrocytes and Fos-positive neurons were increased after exposure for one time. They showed similar topographic localization and formed close relationship. Their number increased as the exposure times increasing, and decreased gradually after 14 days. The reaction of 130dB group was stronger than that of 90dB group.Conclusions 8Hz, 90dB/130dB infrasound can activate both astrocytes and neurons in rats' medulla oblongata which might participate and regulate the response to infrasound.

Spinal biomechanics, especially the range of spine motion,has close connection with spinal surgery. The change of the range of motion (ROM) is an important indicator of diseases and injuries of spine, and the essential evaluating standards of effect of surgeries and therapies to spine. The analysis of ROM can be dated to the time of the invention of X-ray and even that before it. With the development of science and technology as well as the optimization of various types of calculation methods, diverse measuring methods have emerged, from imaging methods to non-imaging methods, from two-dimensional to three-dimensional, from measuring directly on the X-ray films to calculating automatically by computer. Analysis of ROM has made great progress, but there are some older methods cannot meet the needs of the times and disappear, some classical methods such as X-ray still have vitality. Combining different methods, three dimensions and more vivo spine research are the trend of analysis of ROM. And more and more researchers began to focus on vivo spine research. In this paper, the advantages and disadvantages of the methods utilized recently are presented through viewing recent literatures, providing reference and help for the movement analysis of spine.
