1. Study name: A Prospective Study of the Renal artery fibromuscular dysplasia Registry in China 2. Rationale: Fibromuscular dysplasia (FMD) is an idiopathic systemic noninflammatory arterial disease resulting in narrowing of medium-sized arteries. Renal arteries are most commonly involved vessels, although it can also affect arteries in other vascular territories. Renal artery FMD is the second frequent cause of renovascular hypertension , especially in adolescents. The pathogenesis of FMD is still not understood. There were little Asians in the United States and the European/International FMD registry. 3. Objective: 1) To describe the characteristics of renal artery FMD; 2) To identify environmental/ hormonal factors and exposures (for example smoking) associated with the onset and progression of renal artery FMD; 3)To identify baseline characteristics of the disease associated with an increased risk of complications such as dissections, aneurysms, stroke or myocardial infarction; 4) To provide evidence-based algorithms for the management and follow-up of patients with renal artery FMD; 5) To establish a comprehensive imaging resource including a wide range of presentations of renal artery FMD. 4. Study design: Prospective, multi-center, observational study. 5. Study population: renal artery fibromuscular dysplasia 6. Data Collections: 1) Data on demographic characteristics, clinical characteristics, blood routine, biochemical and plasmic electrolytes and vascular imaging were collected using a questionnaire; 2) The diagnosis of renal artery FMD was based on the identification of focal or multifocal FMD lesions in at least one arterial bed by computed tomography angiography, magnetic resonance angiography and/or digital subtraction angiographies; 3) For the patients with renal artery FMD, screening was performed to assess most arteries and multivessel FMD would be collected; 4) All patients would be followed up. 7. Treatment: Standardized diagnosis and treatment procedure as recommended in the International Consensus on the diagnosis and management of fibromuscular dysplasia. 8. Follow up: 3, 6, 12 months after diagnosis and every year after enrolled. 9. Sample size estimation: About 5 hundred. 10. Timeline: Start of subjects' enrollment: Jan 2021; End of subjects enrollment: December 2026; End of study: December 2036. 11. Organization: The Centre for Epidemiological Studies and Clinical Trials, Ruijin Hospital, Shanghai, China.
Arteriovenous Fistula (AVF) is a surgically created circuit used for hemodialysis in patient with End Stage Renal Disease (ESRD). A functioning dialysis vascular access is critical to the delivery of life-saving hemodialysis (HD) treatment for these patients. Unfortunately, neointimal hyperplasia frequently occurs within the dialysis vascular access, resulting in stenosis, poor flow and thrombosis with loss of function. The cephalic vein forms the outflow conduit for radiocephalic (RC) and brachiocephalic (BC) AVF. At the perpendicular portion of the cephalic vein, the cephalic arch is often prone to developing hemodynamically significant stenosis. The prevalence of cephalic arch stenosis is reported to be 39% in brachiocepahlic and 2% in radiocephalic AVF. The current gold standard therapy for treatment of AVF stenosis is plain balloon angioplasty (BA). Paclitaxel coated balloon (PCB) angioplasty has also been shown recently to be superior to plain BA in the treatment of stenosis in dialysis vascular access. By releasing paclitaxel, which is an anti-proliferation drug, locally into the vessel wall during balloon contact, it will blunt the acceleration of intimal hyperplasia response, resulting in improved primary patency after angioplasty. The use of stent grafts for recurrent CAS has been demonstrated to increase patency of AVF compared to BA and bare stents. However, stent grafts are prone to edge restenosis that tend to occur within 5mm of each end of SG due to neointimal hyperplasia from the end of the stent migrating towards the center. We postulate that stent graft with PCB angioplasty of the stent edge is more effective than PCB alone in maintaining the patency of AVF with cephalic arch stenosis. Therefore, we aim to perform a randomized controlled trial to compare the 6-month unassisted patency rate of treatment of recurrent CAS with stent graft and PCB angioplasty of both stent edge versus PCB alone.
A prospective, multicenter, blind randomized (2:1) controlled study comparing the International Prostate Symptom Score (IPSS) of the Active arm to the IPSS of the control arm at the 3 months follow-up and active arm IPSS score change from time zero to 12 months. Patients in the active arm undergo Butterfly device treatment. Patients in the control arm undergo a sham rigid cystoscopy procedure
This study evaluates the long term safety and efficacy of use of the Butterfly Medical's prostatic retraction device in Benign Prostatic Hyperplasia (BPH) Patients. The study follows patients implanted with the Butterfly device for up to 5 year after implantation. The evaluations include recording of safety events and BPH related symptoms by Uroflowmetry tests, residual urine and International Prostate Symptom Score (IPSS) questionnaires. The study also assesses the sexual quality of life after implantation of the Butterfly device.
To investigate the efficacy of GnRHa plus letrozole vs Diane-35 plus metformin in non-obese progestin-insensitive early-stage endometrial cancer (EEC) and atypical hyperplasia(EAH) patients asking for conservative treatment.
To investigate the efficacy of weight management plus levonorgestrel intrauterine system (LNG-IUS) or megestrol acetate (MA) in obese patients with endometrial atypical hyperplasia (EAH) asking for conservative therapy.
This study will prospectively enroll a total of 1000 patients (200 per year) simple hyperplasia/complex hyperplasia (SH/CH) without atypia. All subjects will receive education for exercise and weight control and be randomized 1:1 to with or without metformin intervention. At the end of this 3-year project, an interim analysis will be performed. Since long-term follow-up is intended, therefore for the 4th to 6th year a new grant support will be looked for. The long-term occurrence of endometrial cancer (up to15 years) data will be acquired from national cancer registry, which permission is addressed in the informed sent.
