Objective To evaluate the level situation of clinical doctors graduating from mil-itary medical university within a certain period, understand their career development, and explore and analyze the problems and deficiencies in doctoral education and training to provide reference for deep-ening the reform of clinical disciplines doctoral education. Methods Stratified random samples of 9 Hospitals were selected and the established evaluation index system of clinical discipline quality tracking and investigation questionnaire was used to evaluate doctoral quality. Evaluation was surveyed by self rating and other rating combination. Quality evaluation system contains 4 first level indicators such as the military and political quality, clinical, teaching and research level, the development po-tential as well as 15 second-level indexes. The scores of self-assessment and other evaluation were compared by Pearson rank correlation analysis. The corresponding indicator scores of different doctorate types were compared using the test of variance and the subject research and published papers were analyzed by χ2 inspection. Results The comprehensive score of graduated doctors is excellent, with self-evaluation score (92.72±7.06) and other evaluation score (93.61±8.05). Correlation coefficient is 0.33(P=0.04); The academic doctors have done better in publishing papers(χ2=5.97, P=0.01) and undertaking subject research(χ2=6.08, P=0.00), but poorer in clinical work compared with the doctors of professional degree. The assessed groups are inadequate in publishing high level papers and in un-dertaking research projects and doctors of different degree types have different cognition of the ele-ments of improving the quality. Conclusions Cultivating the doctors' clinical ability and innovation ability are the cores of deepening the reform of clinical doctoral education. We should focus on inno-vation ability , value the cultivation of the clinical professional doctoral degree and explore various joint evaluation systems to attain the goal of enhancing the education quality of doctors.

AIM: To search for new candidate partners of human cell division cycle gene 14A (hCDC 14A) and explore their functional relationships.METHODS: Yeast two-hybrid screening was employed to find hCDC 14A new partners. Physical interaction between two proteins was verified using Pulldown and co-immunoprecipitation assays. Subcellular localizations were revealed by immunofluorescence. In vivo ubiquitination test implied their potential functional relationship.RESULTS: BRAP2 (BRCA1 associated protein 2) was found to be a new candidate partner of hCDC 14A. hCDC 14A was modified by ubiquitination, and BRAP2 increased this modification in vivo. As expected, hCDC 14A and BRAP2 co-localized on mitotic spindles in HeLa cells.CONCLUSION: BRAP2 may be an ubiquitin E3 ligase of hCDC 14A.

Objective To discuss the relations between optimal surgical margin and local recurrence and the impact of preserving segment of sacral nerve root on neural functions based on the clinical and pathological features of giant cell tumor(GCT).Methods From August 1996 to August 2008,48 patients with sacral GCT undergoing tumor resection were respectively analyzed,including 20 males and 28 females with an average of 34.7 years(range,19-74).The tumors were located in S1-S5 in 4 patients,S1-S4 in 7,S1-S3 in 15,S1,2 in 12,S2-S5 in 8,and S3-S5 in 2.Surgical methods included single posterior approach in 29 cases,combined anterior-posterior approach in 19.The surgical margins adopted were en-bloc in 2 patients,marginal in 15,marginal and curettage in 25,and curettage in 9.Results Forty-one of 48 cases were successfully followed up,the average time was 43.5 months(range,18-115).The average blood loss during surgery was 3560 ml(range,550-12 000).Benign lung metastasis occurred in one case 6 years after operation,2 patients died of malignant transformation.Local recurrence occurred in 15 cases.The recurrence rates in patients with en-bloc resection,marginal resection,marginal resection combined with curettage,and curettage were 0,18.2%,40.9%,66.7%,respectively.The recurrence rate of marginal group was significantly lower than that of the curettage group.Of 27 cases with bilateral S3 nerve root preservation,2 sufiered from urine or fetal dysfunction.with an incidence rate of 7.4%.While 4 of 12 patients with unilateral S3 nerve root preservation suffered from sphincter disturbance,with an incidence rate of 33.3%.The significant difference between groups in nerve root preservation was confirmed.Conclusion Optimal surgical margin for sacral GCT is of great importance to local control of tumor recurrence,the surgical procedure of sacral GCT should aim at the marginal resection on the basis of rational sacral nerve roots preservation;preservation of bilateral S3 nerve roots contributes to the recovery of sphincteral function in most patients.

Objective To evaluate the PSD-007-mediated photodynamic effect on mouse osteosarcoma cell line LM-8, both in vitro and in vivo. Methods LM-8 cells were incubated with different concentrations of PSD-007 for 4 hours and then followed different laser irradiations. After photodynamic therapy (PDT), cell viability was measured using MTT assay and the optical density in each experiment was measured at 450 nm with a micro plate reader. The inhibition rate of cell growth was calculated. Four-week-old female C3H mice were used for implantation of LM-8 cells. When the diameter of tumor reached up to 7-8 mm, the mice were randomly divided into following groups: 1) control group, including untreated control, saline with laser irradiation, PSD-007 without laser irradiation; 2) PDT group, PSD-007 (5 and 10 mg/kg) was injected intravenously into the mice, and the tumor site was irradiated with laser light 6 hours after injection. Seven days after PDT, the size and weight of the tumors were measured. The inhibition rate of tumor was calculated, and all tumor specimens were taken for pathologic examination. After the diameter of tumor was 10-12 mm, the tumors were performed a marginal resection and subsequently followed 3 different treatments: without PDT (control), PDT with 240 J/cm2 or 360 J/cm2 laser irradiation. After 4 weeks treatment, the tumor recurrence rates were analyzed. Results MTT assay revealed that the cytotoxic effect of PDT on the LM-8 cells was positively correlated with the concentration of PSD-007 and the level of laser irradiation. When the concentration exceeded 4μg/ml, and the energy exceeded 6 J/cm2, the inhibition ratio was over 50%. No anti-tumor effect was observed in the cells treated with only laser irradiation or PSD-007 injection. Compared with the control group, the size and weight of the tumors were obviously decreased after PDT. PDT performed after marginal resection of the tumor reduced the rate of local recurrence. Conclusion PDT with PSD-007 showed cytotoxic effect on the LM-8 cells, and which performed after marginal resection of the tumor reduced the rate of local recurrence.
