Different procedure of percutaneous endoscopic lumbar discectomy (PELD) was with ventral decompression of dural sac on the lumbar spinal stenosis remains unkonwn.The traditional transforaminal endoscopic spine system (TESSYS) of PELD has been used in clnical for many years, but cannot achieve dorsal decompression. A newly developed modified TESSYS procedure, "U" route PELD combining ventral and dorsal decompression was introduced. Nevertheless, the superior between TESSYS and "U" route PELD procedures on treating LSS remains unknown. This study is desinged to recruit degenerative lumbar spinal stenosis patients who underwent TESSYS or "U" rout PELD, recruited from January 2014 to December 2017. These patients will be followed up for 2 years, and assessed the minimum dura sac cross sectional area (mDCSA) by MRI, and visual analogue scale (VAS) and Oswestry Disability Index (ODI) at pre- and post-operation. The global clinical outcomes were evaluated using modified MacNab criteria postoperatively. Thus, comprehensively evaluate the safety and therapeutic effects of the two PELD procedures on LSS treatments.

Thirty active male and female athletes will be recruited for the study. Subjects will be examined at baseline for VO2max performance. Subjects will then be stratified and randomly divided equally (50% - 50%) into an Oceanix (supplemental) or placebo condition such that baseline VO2max match. Once randomization, subjects will be baseline tested for multiple measures of muscle force capacity, muscle soreness, immune function, and endocrine function. Upon completion of baseline testing, subjects will all complete a one-day, cross-training course in Tampa, Florida. The training course is known to be extremely vigorous and causes significant muscle damage. Subjects will then be retested for muscle function at 24, and 48 hours following the course. At 24- and 48-hours subjects will be asked to repeat a simulated time trial race. In this way, we will measure repeated race performance, recovery from intense exercise, muscle damage from exercise, and immune function during multiple races.
