Research Title:A study on 3D printing-assisted platelet-rich plasma combined with autologous periosteum-bone grafting in the treatment of knee cartilage injury Objectives:(1) To evaluate the accuracy of cartilage damage repair by measuring the chimerism and surface curvature matching degree of 3D printing reconstruction. (2) 3D printing assisted platelerichplasma (PRP) combined with autologous periosteumBone grafting in patients with knee cartilage injury was evaluated for functional and imaging scores to evaluate the clinical effect and cartilage repair effect. Design Type:Prospective randomized controlled trial Research Objects:Unilateral knee cartilage injury area\>2CM2, international cartilagerepair society (ICRS) grade 3-4 patients Sample size: 60 cases (30 patients with 3D printing-assisted autologous periosteum-bone grafting, 3D printing-assisted PRP combined with autologous periosteum.) - 30 patients with bone grafting).Selection Criteria:(1) Age 18\~65 years old; (2) The body mass index (BMI) is 18\~30kg/m2 ； (3) Knee cartilage injury confirmed by imaging examination, knee cartilage injury 2\>cm2, ICRS grade 3-4; (4) There is no obvious abnormality in the lower limb force line; (5) No other drug injection or surgical treatment has been performed locally in the knee joint in the past 1 year. Observation indicators:(1) Clinical function(2) Imaging evaluation: Bilateral knee MRI examination was performed on the second day after surgery Statistical analysis methods:SPSS software was used for data analysis.
NCT07167797
The aim of this study is to evaluate the effect of vitamin D supplementation on the clinical outcomes including duration and severity of rotavirus-induced gastroenteritis in children that will be admitted to the hospital. And to evaluate the anti-inflammatory effect of vitamin D on the pediatrics with rotavirus gastroenteritis by measuring inflammatory markers such as C-reactive protein (CRP), neutrophil to lymphocyte ratio (NLR), platelet to lymphocytes ratio (PLR), lymphocytes to monocytes ratio (LMR) and mean platelet volume MPV.
