After the basic contents of MOOC and flipped classroom were introduced, MOOC-based flipped classroom teaching model for Chinese medical literature information retrieval course was described, its design and implementation were elaborated with CBM Database as an example.

Taking Liaoning University of Traditional Chinese Medicine as an example, a survey of seven-year program students in-formation quality is made.Based on the survey result, it discusses the content, teaching method and approach reform of Traditional Chi-nese medicine literature and information retrieval course for seven-year program students, so as to make better contribution to improving the information literacy of the seven-year program students.

The paper analyzes current situation of the non -medical majors and literature information retrieval course in Traditional Chinese Medicine ( TCM) colleges and universities , points out the course reform objectives and key points .By taking Liaoning Universi-ty of Traditional Chinese Medicine as an example , it discusses the characteristics of non -medical majors and needs for the literature in-formation retrieval course , and proposes the teaching approach of literature information retrieval course for non -medical majors in TCM colleges and universities .

The paper introduces the research significance of Traditional Chinese Medicine ( TCM) literature information retrieval based on cognition analysis, by analyzing cognition of literature information demands of TCM students in different majors of Liaoning University of Traditional Chinese Medicine, it studies from three perspectives:literature information retrieval demand, retrieval thinking and development direction of TCM literature information retrieval system.It also points out that study on thinking and practice of literature information retriev-al based on cognition analysis is the effective approach to enhance information literacy and improve the comprehensive quality.

Objective To evaluate the inhibitory effect of endostatin on bladder tumor and to investigate the possible mechanism of the inhibition. Methods (1)By means of MTT method,the effects of endostatin on ECV304 and EJ cells proliferation were studied.(2)Ten nude mice were subcutaneously implanted with EJ bladder tumor cells (1?10 7/ml). After the tumor volume exceeded 100～200 mm 3,the mice were randomized into two groups.One group received recombinant human endostatin (2 mg?kg -1 ?d -1 ) whereas the other group received PBS as control.All the treatment lasted 21 days.(3) After that,the mice were sacrificed and then MMPs and TIMPs mRNA expression were measured in implanted tumor by RT PCR and Western blot method. Results (1)Endostatin inhibits ECV304 proliferation stimulated with bFGF (5 ng/ml).In addition,we report for the first time that endostatin also inhibits EJ cells proliferation.(2)The mean tumor weight of endostatin treated group (0.70?0.16 g) was significantly lower than that of control group (1.14?0.21)g, P

On the basis of reviewing the significance of retrieval teaching and scientific research integration and the research situation at home and abroad,the paper proposes the undergraduate teaching optimization plan of literature information retrieval of Traditional Chinese Medicine (TCM) teaching integrated with scientific research,points out that the teaching design should focus on the cultivation of scientific research ability,the teaching process advocates the efficient and rich communication form based on the students,and the course assessment should establish multi-dimensional evaluation system.

Objective To evaluate the clinical value of anastomate in treatment of rectal lesion. Methods The anastomate was used to resect space occupying lesion which was 5~12cm from anal.Then thwe operation procedure,operation time, recurrence complications and correlated problems were summarized.Results The average operation time was 34 minutes. Exceot for one case of anastomtic bleeding and one case of recurrence 14 months post operation.there were No other complications.Conclusions Stapling-resecting the rectal lesion was feasible,but some problems were solved from the design of anastomate.

Objective To investigate the diagnosis and treatment of sacral nerve dysfunction syndrome.Methods Accepted 44 cases of sacral nerve disorder syndrome from Oct.2010 to Oct.2012 in the Department General Surgery of Xiangyang Central Hospital,the diagnosis and treatment of sacral nerve dysfunction syndrome were retrospectively analyzed.Results All 44 patients in this group were founded been with lumbar protrusion of the intervertebral disc,the incidence of waist 4-5 or/and sacral 1 intervertebral disc herniation was 100％.Twentyone patients were complicated with vertebral degenerative changes,6 cases with spinal arachnoid cyst.metastatic cancer without treatment in 1 case was exception,13 cases were boarded during sleeping,12 cases were given dehydration treatment with mannitol,15 cases were given therapy of sacral canal nerve block,3 cases were treated by operation.All of these treatment were proved effective.Conclusion Some certain curative effect was obtained through the local physical therapy,systemic dehydration treatment,local nerve block treatment and opertion treatment.

Objective To investigate the relationship among Survivin, PTEN and the occurrence, development, soakage and prog-nesis of gastric cancer. Methods The in-situ hybrization technique, immunochemistry and TUNEL method were used to detect the expres-sion of survivin mRNA, PTEN protein and apoptotic cell. Results The positive rate of survivin expression in gastric cancer was obvious higher than that in para-cancer tissue(P <0.01). Moreover, survivin expression rate in advanced clinical stage and low differentiation gastric cancer degree.was higher, compared with para-cancer tissue (P <0.01, P <0.05). The positive rate of PTEN expression in gas-tric cancer was obvious lower than that in pars-cancer tissue (P <0.01). The positive rate of PTEN expression in advanced clinical stage and low differentiation degree of tissue in gastric cancer was lower (P < 0.01). Furthermore, survivin and apoptesis indexes manifested negative relationship in gastric cancer(r =-0.861, P < 0.01), While PTEN and apoptosis indexes manifested positive relationship (r = 0.832, P < 0.01). Conclusions Survivin could be used as a novel marker to detect gastric cancer. PTEN gene lost function, which maybe promote the origin, growth, soakage and metastasis of gastric cancer.

Objective To explore the effects of angled abutments on the anterior maxilla implant restoration. Methods We analyzed the biomechanical properties of implants of different sizes (Φ3.5 mm,4.0 mm and 4.5 mm in diameter;L11.5 mm and L13 mm in length)after connecting different angled abutments (0°,10°,20°,and 30°) using finite element method.Results The stresses and strains of loading parts of restorations increased and their distribution became more concentrated as the angle of abutment increased.Cortical bone of Φ3 .5 implants with smaller angle (10°or less)andΦ4.0 implants with abutments had the risk of overpassing the bone elastic threshold when the angle approached 30°.However,the cortical bone elastic deformation was within a safe range at all angles inΦ4.5 group.Conclusion We should consider the diameter of the implant when selecting angled abutments.The angled abutments are not suitable for small diameter implants.The bite force should be under control when needed. The larger angled abutments can be applied in the standard and major diameter implants and it is necessary to avoid occlusal overloading.
