ABSTRACT
Objective To compare the effect and safety of stenting versus directional atherectomy (DA) in the treatment of TASCⅡ A and B superficial femoral artery lesions.Methods 100 patients with TASC Ⅱ A and B lesions were divided into percutaneous transluminal stenting(PTS) group (n =50) and DA group (n =50).Patients were compared in terms of technical success rate,treatment success rate,first operation cost,postoperative ankle brachial index (ABI),limb salvage rate,survival,and patency.Results The technical success rate in both PTS and DA group was 100％.The treatment success rate was 98％ vs.86％,P＞0.05.Postoperative ABI:0.82 ±0.19 vs.0.80 ±0.27,P＞0.05.First operation cost:(34 820 ± 1 051) yuan vs.(45 635 ± 1 358) yuan,P ＜0.001;All patients were followed-up for up to 2-year,the cumulative patency rate was 81.6％ vs.72.9％ (P＞0.05).Limb salvage rate was 97.9％ vs.93.8 ％,P ＞ 0.05.Conclusion There were no significant differences in the effect and safety of PTS versus DA in the treatment of TASCⅡ A and B superficial femoral artery lesions.
ABSTRACT
Objective To investigate methods and results of endovascular treatment in TASC (Ⅱ) D-type femoral artery occlusion. Methods From January 2012 to May 2013, 26 cases (26 branches) of superficial femoral artery occlusion with endovascular treatment of TASC (Ⅱ) D-type superficial femoral artery occlusion were retrospectively reviewed. The effi-cacy was evaluated through ABI, CTA, DSA and symptoms improved. Results 26 branches were treated with endovascular methods. Technical success rate was 80.7%(21/26), including 13 branche with stent implantation, 6 branches with Silver-hawk atherectomy and 2 branches with Viabahn stent implantation. All patients were followed up for a mean period of (10.3 ± 1.2)months, primary patency rates at 6 months were 69.2%in stent group, 66.7%in Silverhawk atherectomy group and 100%in Viabahn stent group. Conclusion Endovascular treatment of TASC (Ⅱ) D-type femoral artery occlusion can lead to satisfactory short term patency rates, and Viabahn stent is the latest treatment.
ABSTRACT
Using pesticides has double effects
On one hand, it contributes to pests control and regulates the growth of crops; On the other hand, it does harm to the environment
To develop ecological agriculture should not only emphasize the output level of agriculture to pursuit of economic efficiency, but also need to keep the ecological environment protected and focus on the social benefits during the development of the industry. As a large agricultural country in the world, China is vigorously promoting the development of ecological agriculture, which is bound to put forward to developing the pesticide industry and green ecological development requirements to promote the transformation and upgrading of agricultural pharmaceutical industry
This paper discusses the mechanism of pesticide pollution on the ecological environment and analyzes China's agricultural problems in the pharmaceutical industry. Then study on the development of Chinese green pesticides and try to find the proper paths of agricultural pharmaceutical to achieve industrial upgrading
