Conclusions The implementation of clinical scenarios discussion before clinical probation was effective on inducing the medical students to pay attention to the doctor-patient communication, and deep thinking about the communication notice mat-ters and cop-ing styles in clinical environment.

Objective To provide a new method for sacral fracture fixation by means of 3D recon-struction and reverse engineering technique. Methods Pelvis images of 3D CT scan were obtained from patients with sacral fracture. The digital data were transferred into a computer workstation. 3D models of pelvis were reconstructed using Amira 3.1 software and saved in STL format. The 3D fracture models were imported into Imageware 10.0 software. Different situations of reduction (total reduction, half reduction and no-reduction) were simulated using Imageware 10.0 software. The extract locations and the best directions of inserting iliosacral lag screws were defined using Reverse Engineering according to the 3 situations to before navigation templates were designed according to the posterior anatomic features of the ilium and the insertion channels. Exact navi-gational templates were manufactured by rapid prototyping. Drill guides were sterilized and used intraoperatively to assist surgical navigation and placement of iliosacral lag screws. Results Accurate screw placement was confirmed with postoperative X-ray and CT scanning. The navigation templates were found to be helpful and highly accurate. Conclusion The navigation template may be a useful method for mini-invasive fixation of sacroiliac joint fracture.

Objective To establish a breeding method ofMyodes rufocanus in the laboratory,collect their growth and reproduction data,and provide a basis for carrying out the experimental animalization.Methods Wild Myodes rufocanus caught in the Moranbong woodland were brought back to the laboratory.They were bred artificially in a large hard wall rodent negative pressure isolator.Their growth and reproduction data were recorded for evaluating the results of breeding.Results The Myodes rufocanus were successfully bred in the laboratory.The pregnancy rate was 54.55%.The average pregnancy length was 20.4 days(8 to 22 days).During one breeding period,they gave birth 2.9 times on average.The maximum number of births was 7 times,far more than the number tested under field conditions.The average litter size was 4.3±1.22.The highest litter number of a single nest was 8.The weaning rate of pups was 94.8%.The growth and development of pups were good.Conclusions The breeding method for Myodes rufocanus is established.The growth and reproduction data are tested too.The results of our study laid a foundation for the experimental animalization of Myodes rufocanus.

ObjectiveTo study prognostic factors and surgical extent of papillary thyroid microcarcinona (PTMC). MethodsLiteratures about PTMC were searched. Relationship between prognostic factors and recurrence after initial operation was analyzed by meta analysis. The surgical extent of PTMC was discussed. Results A total of 12 retrospective studies were included. Meta analysis results showed that factors such as male, tumor size ＞ 5 mm, nonincidental, positive lymphnode, multifocus, and capsular invasion were related to recurrence after initial surgery. Age above 45 years had nothing to do with the recurrence rate of PTMC. There was no signifi.cant difference in recurrence rate between prophylactic neck dissection groups and the groups without prophylactic neck dissection. ConclusionsMany factors are related to the prognosis of PTMC. The surgical extent depends on prognostic factors. Prophylactic neck dissection is not supposed to be conventional surgical procedure for PTMC. Bilateral central lymph node dissection is appropriate to PTMC with positive lymph node.

Objective To investigate if rat enhancer of split- and hairy-related protein-2 (SHARP-2) short hairpin RNA interference (shRNAi) prolongs the survival time of rat kidney transplant recipients. Methods Gene recombinant procedures, transfection and co-transfection were carried out to introduce short hairpin RNA interference sequences target for SHARP-2 into 3rd generation self-inactivated lentiviral-ViraPower packaging mix. Limiting dilution method was used for viral titration. Real-time PCR was employed for quantification of gene expression. Rat kidney transplantation was utilized to investigate the effect of SHARP-2 gene silence on the recipient survival. Results A lentiviral-based shRNAi construct LV-SHARP-2iC showed 84% SHARP-2 gene silence efficiency in normal rat kidney cells. At multiplicity of infection 20, 57% T cells could be transfected by lentivirus with spinoculation method. In activated T cells, SHARP-2 g ene silence resulted in 61.3% and 68.7% reduction of intedeukin 2 (IL-2) and interferon γ (IFN-γ) gene expression. When donor kidney was perfused with 5×107 TU LV-SHARP-2iC, the median survival time prolonged for 4-5 days as compared to blank and scramble control groups. Conclusions A recombinant lentivirus LV-SHARP-2iC that effectively silence SHARP-2 gene expression is constructed successfully, leading to the inhibition of IL-2 and IFN-γ. LV-SHARP-2iC treatment can prolong the survival time of rat kidney transplant recipients.
