A well Web-based teaching supplementary system is beneficial for saving teaching resources,arousing students’enthusiasm for study.but there is no the emotion exchange between teachers and students which exists in traditional class.Web-based supplementary teaching is an important supplementary method for medical morphology courses,but it can not replace the traditional teaching method.Combining them each other is needed for raising teaching quality.

Test is an important way for getting feedback from students about teaching. The traditional examination is not suitable for the requirements of modernization teaching.Web-Based Course Examination of practice pathology simplifies the process of traditional examination greatly. It is one of the important means in modernization teaching.

Objective To explore the effect of intra-and post-operative administration of supplemental high concentration oxygen on abdominal clean-contaminated surgical wound infection.Methods From January 2001 to June 2005, 425 patients undergoing abdominal clean-contaminated operation were randomly divided into receive FiO2 60 % (n=213, study group) or FiO2 28 % (n=212, control group) inspired oxygen during the operation and two hours postoperatively. The partial pressure of oxygen in arterial blood and the peripheral arterial oxygen saturation was were measured two hours after operation. During 15 postoperative days, the wounds that drained pus were considered infected.Results The results showed that the partial pressure of oxygen in arterial blood was significantly higher in the study group than in the control group (P

In order to investigate biological functions of the 14-3-3 genes and their response to abiotic stress, two cDNAs (designated as Ta14R1 and Ta14R2) encoding putative 14-3-3 proteins were isolated from wheat by PCR and rapid amplification of cDNA end (RACE) technique. The cDNA of Ta14R1 is 999bp and encodes a protein of 262 amino acids, while the cDNA of Ta14R2 is 897bp in length and encodes a protein of 261 amino acids. Transient expression assays using Ta14R1/Ta14R2-GFP fusion constructs indicated that Ta14R1 and Ta14R2 were located in cytoplasm and cell membrane but not in chloroplasts. Real-time quantitative (RT-PCR) analysis revealed that Ta14R1 and Ta14R2 were differentially expressed in wheat tissues and significantly up-regulated in roots and shoots 1d after germination, indicating they may play a role in process of seed germination. The expression of the two genes in roots and leaves were significantly induced by plant hormone ABA, as well as heat, cold and drought treatments, suggesting that the two 14-3-3 genes in wheat may be involved in ABA dependent stress-responding pathway and response to heat, cold and drought stress.
