Objective To explore the effects of PBL teaching method on classroom atmosphere of basic nursing course.Methods Two classes of nursing sophomore were enrolled and were divided two groups,60 as PBL group and other 60 as traditional group.Students in two groups were evaluated by questionnaire of classroom atmosphere.Data were statistically analyzed through t-test,P＜0.05 standing for statistical significances.Results There were statistical differences in classroom atmosphere between two groups (P ＜ 0.05) ; class democracy,elicitation in teaching and student cooperation in PBL group were significantly better than those of traditional mode (P ＜ 0.05).There was no significant difference in learning autonomy between the two groups (P ＞0.05).Conclusions PBL teaching is conductive to stimulating students' learning potentials,culturing their cooperative learning,raising the efficiency of classroom learning and improving the classroom atmosphere.But learning autonomy of students needs to be further improved.

Current therapies of organ failure or a wide range of tissue defect are often not ideal. Transplantation is the only effective way for long time survival. But it is hard to meet huge patients demands because of donor shortage, immune rejection and other problems. Tissue engineering could be a potential option. Choosing a suitable scaffold material is an essential part of it. According to different sources, tissue engineering scaffold materials could be divided into three types which are natural and its modified materials, artificial and composite ones. The purpose of tissue engineering scaffold is to repair the tissues or organs damage, so could reach the ideal recovery in its function and structure aspect. Therefore, tissue engineering scaffold should even be as close as much to the original tissue or organs in function and structure. We call it "organic scaffold" and this strategy might be the drastic perfect substitute for the tissues or organs in concern. Optimized organization with each kind scaffold materials could make up for biomimetic structure and function of the tissue or organs. Scaffold material surface modification, optimized preparation procedure and cytosine sustained-release microsphere addition should be considered together. This strategy is expected to open new perspectives for tissue engineering. Multidisciplinary approach including material science, molecular biology, and engineering might find the most ideal tissue engineering scaffold. Using the strategy of drawing on each other strength and optimized organization with each kind scaffold material to prepare a multifunctional biomimetic tissue engineering scaffold might be a good method for choosing tissue engineering scaffold materials. Our research group had differentiated bone marrow mesenchymal stem cells into bile canaliculi like cells. We prepared poly(L-lactic acid)/poly(ε-caprolactone) biliary stent. The scaffold's internal played a part in the long-term release of cytokines which mixed with sustained-release nano-microsphere containing growth factors. What's more, the stent internal surface coated with glue/collagen matrix mixing layer containing bFGF and EGF so could supplying the early release of the two cytokines. Finally, combining the poly(L-lactic acid)/poly(ε-caprolactone) biliary stent with the induced cells was the last step for preparing tissue-engineered bile duct. This literature reviewed a variety of the existing tissue engineering scaffold materials and briefly introduced the impact factors on the characteristics of tissue engineering scaffold materials such as preparation procedure, surface modification of scaffold, and so on. We explored the choosing strategy of desired tissue engineering scaffold materials.

Objective To investigate the correlation between TIP 30 and VEGF-C expression and clini-cophathological characteristics in resected small cell lung cancer ( SCLC) patients and to identify patients with in-creased risk of cancer recurrence and to provide a theoretical basis for the further clinical prevention of SCLC . Methods Sixty eight resected SCLC patients were included in this study .Paraffin-embedded specimens of pa-tients were used for the evaluation of TIP 30 and VEGF-C expression by immunohistochemistry .Results The expression of VEGF-C had positive correlation with lymph node metastasis .TIP30 expression was positively cor-related with VEGF-C expression.Patients with low TIP30 expression had shorter Overall survival (OS)and Dis-ease-Free survival(DFS)than those with high TIP30 expression.OS and DFS of the patients with VEGF -C-positive tumors were significantly lower than that of the patients with VEGF -C negative tumors .The multivariate Cox regression analysis showed that low TIP 30 and high VEGF-C expression were independent markers of poor OS(P<0.01)in operable SCLC patients.Conclusion The expression of VEGF -C shows positive correlation with lymph node metastasis .Low TIP30 and high VEGF -C expression are independent prognostic markers of poor overall survival in resected SCLC patients .

BACKGROUND:The CD133 expression in non-smal cel lung cancer shows some changes, which is definitely related to the occurrence and development of diseases. OBJECTIVE:To investigate the expression of CD133 in non-smal cel lung cancer, and to analyze its relationship with clinical pathological factors and prognosis. METHODS:Non-smal cel lung cancer tissue specimens from 135 cases were col ected, and normal lung tissue specimens from 60 cases were set as normal control group. Immunohistochemical staining was used to detect CD133 expression in two groups, and the relationship between the expression of CD133 protein and the clinical pathological factors was analyzed. RESULTS AND CONCLUSION:(1) The positive expression of CD133 protein in the non-smal cel lung cancer group was significantly higher than that in the normal control group (P<0.05). (2) CD133 protein expression had no association with age, gender, tumor size, tumor location, histological type (P>0.05), and CD133 protein expression was significantly increased with the differentiation of non-smal cel lung cancer (P<0.05). The positive expression rate of CD133 protein was significantly different between different clinical stages and lymph node metastasis (P<0.05). (3) CD133 and TNM staging were independent prognostic factors for non-smal cel lung cancer (P<0.05), and the median survival time was significantly shorter in the positive group than in the negative group (P<0.05). The results indicate that CD133 is involved in the occurrence, development, infiltration and metastasis of non-smal cel lung cancer, and it has important clinical significance for the disease progression and prognosis.

Objective To explore the differences between the conservative treatment and the operative treatment in the management of cervical spinal cord injury, and the timing of the operation. Methods The therapeutic effectiveness o f the 45 cases who were treated from October 1996 to January 2002 was analyzed. 21 of them underwent conservative treatment and 24 operative treatment. The corr elation between the therapeutic effects of the operation and its timing was expl ored. Results The myeloid functional recovery was poor in the patients who had b een treated with conservative means but good in those who had been given an oper ation. The earlier the operation, the more effective it could be, and the higher the probability of the myeloid functional recovery. Conclusions The operative treatment promises better outcome than the conservative treatment. To get the be st effects, the operation should be done within one month after the injury, for the longer the lapse between the injury and the operation, the worse the effect.
