Objective To study the expression of vascular endothelial growth factor-C (VEGF-C) and VEGF receptor-3 (VEGFR-3) in non-small cell lung cancer (NSCLC), and to explore its relationship with lymph node metastasis. Methods Sixty patients with NSCLC were studied. The expression of VEGF-C and VEGFR-3 was detected by immunohistochemistry in lung cancer samples, and its relationship to clinical and pathological data was analyzed. Results The positive expression rate of VEGF-C in NSCLC tissues was 68.3% (41/60), the expression rate of VEGFR-3 was 53.3% (32/60). The expression of VEGF-C was related with the degree of cell differentiation in lung cancer. Both the expressions of VEGF-C and VEGFR-3 were positively associated with lymph node metastasis. There was a positive correlation between VEGF-C and VEGFR-3 expressions (r=0.27). Conclusion The expressions of VEGF-C and VEGFR-3 are related to lymph node metastasis in NSCLC. VEGF-C may promote intratumoral lymphangiogenesis via VEGFR-3 and lymphatic metastasis.

This article was aimed to study the correlation between iron content inCornus officinalis leaves and its yield as well as quality. The method of microwave digestion atomic absorption spectrophotometer was used to determine the content of iron element inCornus officinalis leaves. HPLC was used to determine the content of loganin and ursolic acid in fruits. Correlation analysis was made among the content of iron element, yield of fruits, loganin and ursolic acid in fruits. The results showed that iron element in leaves of different yield level cornus officinalis was different. It also had some correlation with yield and quality of fruits. It was concluded that the research can improve relations of source-sink inCornus ofifcinalis, adjust source-sink balance, guide farmers to master the period of spraying iron fertilizer, and increase production and quality ofCornus ofifcinalis.

Objective To evaluate early results of Endurant stent-graft in the treatment of abdominal aortic aneurysms (AAAs).Methods From July 2010 to June 2011,68 patients (57 men,11 women; mean age 74.3 years) were treated with Endurant stent-graft at our center.26 cases had hostile proximal neck in the anatomy.According to ASA classification,15 cases were class Ⅱ ; 32 cases were class Ⅲ and 21 cases were class Ⅳ.Results Intraoperative immediate technical success was achieved in all cases.At completion angiography,a type Ⅱ endoleak was detected in 18 (26%) of the 68 patients.The mean operation time was (96 ± 29) min,the mean blood loss was (99 ± 68 ) ml,and the mean contrast usage was (122 ± 65) ml.No intraoperative conversion to open surgery,stent migration,types Ⅰ/Ⅲ endoleak,other major complications,or death was encountered.49 patients (72%) had a postimplantation syndrome with fever,leukocytosis,and increase of C-reactive protein levels,which completely resolved within two weeks.The mean follow-up time was (8 ± 5) months.Conclusions Endurant stent-graft seems to be safe and effective in endovascular aneurysm repair,even in patients with hostile aortoiliac anatomy.

Objective To explore the effect of keratinocyte growth factor(KGF)on the lung tissue and expres-sion of transforming growth factor - β1(TGF - β1 )in newborn rats with hyperoxia. Methods The 108 newborn SD rats were randomly divided into air group,hyperoxia group and KGF intervention group,and each group had 36 rats. The rats in every group were randomly divided into the 3,7,14 days subgroups,and each group had 12 rats. The rats in the hy-peroxia group and KGF intervention group were continually exposed to more than 950 mL/ L of oxygen box until the end of the experiment. KGF intervention group simultaneously undertook oxygen inhalation,hypodermic injection of 1 mg/ d recombinant human KGF(rhKGF)on the back on the first 3 days and 0. 5 mg/ d 3 days later till the end of the experi-ment. Air group and hyperoxia group were offered equivalent 9 g/ L saline. The rats in the air group took air. The sub -groups of the 3,7 and 14 days were cut for lung tissue in the corresponding time,observing lung tissue by light micro-scope for pathological changes and TGF - β1 protein expressed in the lungs was determined by immunohistochemistry. Results Air group sprout pulmonary alveolus on the 7th day,and the alveolaration finished on the 14th day,while hy-peroxia group had alveolar growth retardation and pulmonary fibrosis,but pulmonary fibrosis was not obvious in KGF in-tervention group. There was a significant difference on 7th day and 14th day between hyperoxia group and air group in TGF - β1(9. 43 ± 0. 64 vs 8. 62 ± 0. 52,P ﹤ 0. 05;9. 97 ± 0. 49 vs 8. 66 ± 0. 48,P ﹤ 0. 01). There was no significant difference between KGF intervention group and air group in TGF - β1(8. 67 ± 0. 55 vs 8. 56 ± 0. 43,8. 77 ± 0. 52 vs 8. 62 ± 0. 52,8. 81 ± 0. 47 vs 8. 66 ± 0. 48,all P ﹥ 0. 05). There's a significant difference on 7th day and 14th day be-tween hyperoxia group and KGF intervention group in TGF - β1(all P ﹤ 0. 05). Conclusions KGF can inhibit the pro-tein expression of TGF - β1 ,and this may be one of the possible mechanism underlying the protective effect of KGF a-gainst lung injury.

Objective To probe into the reasons for and results of remedial surgical therapy in thoracic aortic dissection patients after first endovascalar repair.Methods From July 2000 to December 2012,12 cases received second interventional surgery.The average time from second therapy to first surgery was ( 14 ± 11 ) months.Main reasons for second endovascular therapy were sustained type Ⅰ endoleak at proximal landing zone and type A dissection caused by retrograde tear.Therapies included hybrid operations in 8 cases and absnlute endovascular therapy in 4 cases.Results The 30 day mortality after the second intervention was 5.6% ( 1/12),total mortality rate was 16.7% (2/12).In 7 cases with endoleak,small endoleak remained after remedial therapy (57.1% ) in 4 cases.Among 4 cases with secondary type A aortic dissection,successful staged hybrid operation with mid-sternal thoracotomy was adopted in 3 cases,one died of pulmonary emtbolism during follow-up period,1 case with Bebcet disease still had proximal type Ⅰ endoleak after second hybrid operation,and died from tear of aorta.Conclusions Endoleak and secondary type A aortic dissection are the main cause necessitating second intervention after primary endovascular therapy for thoracic aortic dissection.Hybrid operation remains the best choice to treat postoperative complications after endovascular therapy for thoracic aortic dissection.
