月季遗传资源的评价与利用

国产蔷薇属植物82种,约占世界总数的41%.在近200种蔷薇属植物中,只有15种参与了现代月季的形成,新的遗传资源的引入是月季抗性育种的关键.现代月季品种达25000多个,但在欧洲苗圃销售的不到3000个,而以丰花月季为主.月季抗病遗传资源的研究主要针对黑斑病、白粉病和根结线虫.分子标记已广泛应用于月季亲缘关系分析、遗传图谱的构建和品种的鉴定.蔷薇果含有丰富的Vc和药用价值.     

Open Versus Arthroscopic Surgical Management for Recalcitrant Trochanteric Bursitis: A Systematic Review

BackgroundWhile excision of the trochanteric bursae to treat lateral hip pain has increased in popularity, no comparison exists between the surgical outcomes and complications of the open and arthroscopic techniques involving trochanteric bursectomy. The purpose of this study was to determine the efficacies and complication rates of arthroscopic and open techniques for procedures involving trochanteric bursectomy.MethodsThe terms “trochanteric,” “bursectomy,” “arthroscopic,” “open,” “outcomes,” and “hip” were searched in five electronic databases. Fifteen studies from 120 initial results were included. Patient-reported outcomes (PRO), pain, satisfaction, and complications were included for analysis.ResultsFive hundred-two hips in 474 total patients (77.7% female) were included in this study. The average age was 54. The fourteen distinct PRO scores that were reported by the included studies improved significantly from baseline to final mean follow-up (12-70.8 months for open; 12-42 months for arthroscopic) for both approaches, demonstrating statistically significant patient benefit in a variety of hip arthroscopy settings (P > 0.05). The complication rates of all procedures ranged from 0%-33% and failure to improve pain ranged from 0%-8%. Patient satisfaction with surgery was high at 95% and 82% reported a willingness to undergo the same surgery again. No significant mean differences were found between the open and arthroscopic techniques.ConclusionThe open and arthroscopic approaches for trochanteric bursectomy are both safe and effective procedures in treating refractory lateral hip pain. No significant differences in PROs, pain, total complications, severity of complications, and total failures were seen between technique outcomes.Level of Evidence: IV
