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

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.

Cholangiocarcinoma is a highly malignant tumor which originates from bile duct epithelial cells, and its invasion and metastasis is an important factor affecting the prognosis of patients and the main causes of the high mortality.Epithelial-mesenchymal transition is a reversible biological process of transition from epithelial phenotype to stromal cell phenotype, which is closely related to tumor invasion and metastasis.The microRNA is an endogenous non-coding RNA with a sequence of 20~25 nucleotides, which participates in the occurrence and development of tumor, especially in the progress of tumor invasion and metastasis by complementary base pairing with the 3'-untranslated region (3'-UTR) of the target gene at the post-transcriptional level.Herein, we present the mechanism of microRNA regulating epithelial-mesenchymal transition and its effect on the invasion and metastasis of cholangiocarcinoma.

The medical humanistic spirit is very important,but it has been seriously neglected.It is the key to educate medical students with accomplishment of medical humanistic spirit.And it is also necessary to renew the concept of courses,making the relation between the courses of medical humanitic spirit and specialized profession.The Medical College of Shantou University has practised effectively.

? The choroidal vasculature provides oxygen and nutrients to the outer retina, and is responsible for maintaining the highly metabolically active photoreceptor cells. The normal structure and function of its vascular system is very important for the retina. So it is more meaningful to observe the choroid morphology for tracking pathological changes in diabetic retinopathy. With the application of the high resolution optical coherence tomography ( OCT ) technology, spectral -domain optical coherence tomography ( SD - OCT ) enhanced depth imaging technology can be used to measure the choroidal thickness quantitatively, which provides a new idea for the diagnosis and treatment of diabetic retinopathy. Therefore, the research and progress of choroidal thickness on diabetic retinopathy by OCT are summarized as follows.

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.

The baculovirus expression system has been used extensively for the expression of recombinant proteins in insect cells.Recently,recombinant baculoviruses containing mammalian cell-active promoter element have been used to transduce a broad spectrum of primary and established mammalian cells,including non-hepatic cells.Recombinant baculoviruses have been used successfully for transient or stable gene delivery in mammalian cells in vitro,while the efficiency of delivering gene in vivo is inhibited obviously by complements,but efforts have been made to overcome the problems,for instance,VSV-G-pseudotyped baculoviruses display complement resistance.The mechanism of the transduction is still not clearly understood,though many researches have been done.The baculovirus is able to replicate only in insect cells,but it is incapable of initiating replication cycle in mammalian cells,which guarantees high biosafety of this gene delivery system.In addition,this system is easily manipulated and able to carry large inserts.These attributes will undoubtedly lead to the increased application and continued development of this system for highly effective gene delivery into mammalian cells.

Objective To evaluate the effects of nutritional intervention on the incidence of malnutrition in patients on maintenance hemodialysis (MHD).Methods Totally 196 patients on MHD were randomly assigned to nutritional intervention group (n =98) and control group (n =98).Nutritional intervention or free diet were given in these two groups.The incidence of malnutrition in these two groups was recoded.Results The baseline age,biochemical indicators,and incidence of malnutrition were matched in these two groups (P ＞0.05).After 6 months,although the number of the patients with malnutrition [35.7％ (35/98)] was slightly increased in the intervention group,it showed no significant difference when compared with the baseline level [33.7％ (33/98),P ＞0.05].In the control group,however,the incidence of malnutrition [59.2％ (58/98)] significantly increased (P ＜0.05).The incidence of malnutrition was significantly lower in the intervention group than in the control group (P ＜ 0.05).Conclusion Nutritional intervention can lower the incidence of malnutrition in patients on MHD.
