The relationship between vascular endothelial growth factor-C (VEGF-C)/vascular endothelial growth factor receptor 3 (VEGFR-3) expression and clinicopathologic features of the patients with non-small cell lung cancer (NSCLC) was investigated. The expression of VEGF-C and VEGFR-3 was assessed in 65 patients with NSCLC by immunohistochemistry. The significance of VEGF-C and VEGFR-3 expression was analyzed statistically. The results showed that VEGF-C and VEGFR-3 were highly expressed in cytoplasm and membrane in lung cancer tissues with the positive rate being 55.4 % and 52.3 % respectively, while there was no expression in the normal lung tissues. The expression of VEGF-C was significantly increased in adenocacinoma as compared to other types of NSCLC (P<0.05). The VEGFR-3 expression was closely related with lymph node metastasis (P<0.01) and TNM stage (P<0.05). There was a positive correlation between the VEGF-C and VEGFR-3 expression in NSCLC patients (r=0.658, P<0.01). It is suggested that VEGFR-3 plays an important role in the lymphatic metastasis of NSCLC. The interaction between VEGF-C and VEGFR-3 may be deeply involved in the mechanism of lung cancer metastasis.

Objective To study the induction of IL-6 on expression and activity of tissue factor (TF)in peripheral blood monocytes(PBMCs).Methods rhIL-6 100 ng/L and rhIL-6 100 ng/L+ rhIL-6 MoAb 10?g/L were used respectively to stimulate the PBMCs for 24 h,PBMCs without any stimulation as control group,to study the changes of antigen content,mRNA expression and the ac- tivity of the TF.Results The antigen content,mRNA expression and activity of TF were increased significantly in 100 ng/L rhIL-6 group as compared with rhIL-6 100 ng/L+rhIL-6 MoAb 10?g/L and control groups(P＜0.01).Conclusions rhIL-6 can induce the increase of antigen expression,activity and mRNA expression in PBMCs,and these effects can be suppressed successfully by rhIL-6 MoAb. This study demonstrated that there was potential relations between cytokines and thrombogenesis, which may play an important role the pathogenesis of chronic rejection.

Objective To investigate nursing students and nurses' knowledge, attitude and behaviors of standardized treatment of medical waste, so as to develop more constructive advices in future. Methods The survey was conducted in 80 nursing students and 85 nurses in one of the Beijing' s third level 1 class hospitals.The data was analyzed with SPSS 17.0 software. Results Nursing students' scores of knowledge, attitude and behavior were significantly lower than nurses' ( t =- 6.986, - 5.336, - 3.862 ; P ＜ 0. 05 ) ; Nursing students with higher education levels showed significantly higher scores of knowledge ( F =9. 992, P ＜ 0. 05 ), but there' s no significant difference with scores of attitude or behavior( F =1. 279,1. 595 ; P ＞ 0. 05 ) ; Nurses with different education levels, length of service and professional titles showed no significant difference with scores of knowledge, attitude and behavior(P ＞ 0. 05). Scores of nursing students and nurses in behavior were low, and needs to be raised. Conclusions Adequate knowledge is foundation and good attitude is propulsion, they two will be helpful to increase the quality of treatment of medical waste with systematic management and training of the hospital.

Objective To explore the relationship of empathy ability and leadership among nurse managers.Methods 184 nurse managers completed the Interpersonal Reactivity Index-Chinese Version (IRI-C)scale and Leadership Questionnaire for Nursing Manager for empathy and leadership.Results The average score of the empathy is 57.72±8.59,the average score of leadership is 102.38±14.38.The relationship between empathy and leadership is positive and the coefficient of correlation is r =0.21,(P＜0.05).Conclusion The empathy and leadership ability of the nurse managers surveyed are found to be at intermediate level; empathy ability and leadership have positive interactions; and improved empathy ability of nurse managers can strengthen their leadership.

ObjectiveTo evaluate the curative effect of reconstruction of the hand and foot defects with bones and tendons exposure using free medial sural artery perforator flap(MSAP). MethodsRadiographs of 2 cadavers injected with a modified lead oxide-gelatin mixture were digitally analyzed. Between April 2007 and December 2010, thirty-four patients with soft tissue defects in the distal limb were treated with the free MSAP flap transplantation. The sizes of the defect ranged 6 cm × 4 cm-13 cm × 8 cm, and the flaps ranged 7 cm× 5 cm-14 cm × 9 cm. These clinical cases included 25 hands and 9 feet, all of them with bones and tendons exposure.In these defects,twenty-two were clean,twelve got infections.In our cases, twenty-three flaps were nourished with single perforator vessel and else 11 with two;perforator vessel fifteen flaps were dissected one superficial vein to anastomose with that of the recipient sites in addition to accompanying vein anastomosis;The sensation of 9 flaps recovered the hands were reconstructed with cutaneous nerve anastomosis. ResultsA partition of the calf skin blood vessels,and three-dimensional reconstruction image of the sural artery were obtained.All flaps survived,five of them appeared partially violet and bubbles. Followed up 6-21 months, the cosmetic results were satisfactory and without apparent bulkiness.The flap colors were similar to recipient sites. The flap senses reconstructed with neural anastomosis recover to S2-S3. ConclusionThe new flap is very suitable to repair the soft tissue defect in the distal limbs,because the fairly constant perforator vessel,the reliable blood supply and the cosmetic shape of the MSAP flap are all advantages of it in addition to no damage to low leg chief artery and gastrocnemius.

Objective To investigate the status of social support, anxiety and depression of the Amyotrophic lateral sclerosis ( ALS) and its related influencing factors, to provide basis for the treatment and nursing. Methods To investigate 56 amyotrophic lateral sclerosis patients with the Social Support Rating Scale (SSRS), Self-evaluating Measurements of HAMD and HAM A, to statistically analyze social support, anxiety and depression of 56 patients with SPSS 16.0 Statistical Package. Results The total score of social support of the Amyotrophic lateral sclerosis patients was 24 to 53. The average score was (39. 36 ±6. 15) , which was higher than the value of domestic norm (P <0. 05). The incidence rates of anxiety and depression among ALS patients were 26. 79% and 33. 93%. Conclusions The overall status of social support for the Amyotrophic lateral sclerosis patients is good, patients who get more social support get less anxiety and depression. More social support is need for the amyotrophic lateral sclerosis patients who are women, elderly, farmer, ordinary worker and get lower educational level,
