our aim is estimating the Prevalence and predicting risk factors for developing chronic oral graft versus host disease in pediatric patients subjected to hematopoietic stem cells transplantation
To study the outcome of different two endoscopic sphenoid procedure for management of allergic fungal sphenoidal sinusitis : sphenoidotomy versus sphenoid nasalization with posterior septectomy .
A prospective longitudinal cohort study aimed at measuring frailty and its associated risk factors community dwelling older adults aged 65 years or older. The geriatric domains evaluated will include: frailty status, hearing impairment, visual impairment, polypharmacy, sarcopenia, malnutrition, cognitive impairment, depression, fatigue, sleep difficulties, and disabilities. The primary outcome is all-cause mortality at 1-year post enrollment.
The investigators seek to describe the composition, architecture, and electrical conduction properties of the human uterine myometrial artery and their impact on vascular reactivity upon exposure to hypertensive stress. Non-pregnant women and pregnant women with and without hypertensive complications will be studied to evaluate the influence of these states on the myometrial arteries. Vascular over-reactivity and disruption of the normal pregnancy-associated physiologic changes of relaxed vascular tone possess the potential for non-compensated blood flow to the uterus and placenta that is insufficient to meet the metabolic demands of a growing placenta. With an understanding of these changes, the research team will be able to propose basic mechanistic changes of pathologic myogenic tone that may ultimately be investigated as potentially modifiable processes to reduce the development and/or severity of these pregnancy complications (gestational hypertension, preeclampsia, eclampsia, small for gestational age, intrauterine growth restriction and intrauterine fetal demise. ).
1. To detect IKZF-1 deletion mutations in patients with ALL. 2. To study the impact of IKZF-1 deletion mutation on therapy of ALL. 3. To study the correlation between IKZF-1 deletion mutations and BCR-ABL.
To asses causes of shoulder pain by Ultrasound in guide of MRI diagnosis to help Ultrasound to be used alone in the future
Chronic Obstructive Pulmonary Disease (COPD) is a disease with a very high morbidity and mortality rate. When the lung function drops lower and lower, patients will bear great affliction physically and mentally. How to improve the quality of life in patients with COPD is a hot topic in the study of COPD now. Baduanjin, as one of the traditional Chinese qigong exercises, has the features of generous stretch, soft consistency, dynamic but static, which is an appropriate movement pattern for COPD patients.
Adult patients with chronic hepatitis B and cirrhosis of any etiology who are found to have suspected liver cancer are potentially eligible for the study. All enrolled patients will undergo two MRI scans using two different contrast agents. The type of contrast agent for the 1st MRI will be performed using hepatocyte-specific contrast agent. The participant will undergo the 2nd MRI using extracellular contrast agent. The MRI examinations will be independently interpreted by two different radiologists. The radiologists will evaluate focal hepatic lesions and categorize them according to the LI-RADS v2018 and EASL 2018. Once the diagnosis is made, the participants will be provided with the standard of care. After the initial treatment, the participants will be followed up with multi-phasic dynamic contrast-enhanced CT every 3 or 6 months for at least 2 years. Based on the prospectively written radiology reports, the diagnostic performances will be calculated and compared between MRI with hepatocyte-specific contrast agent and MRI with extracellular contrast agent, using the pathology and clinical criteria as the reference standard.
Platelet-rich plasma(PRP), is a concentrate of platelet-rich plasma protein derived from whole blood. The main components of it are platelets, leukocytes and fibrin. Autologous PRP treatment can avoid the immune rejection caused by exogenous growth factor and the spread of disease. Evidence of the efficacy and safety of PRP has been proven in many studies. Benign central airway stenosis is characterized by airway compromise involving the larynx, trachea, or bronchi and will lead to devastating consequences. Unfortunately, the incidence of this disease is increasing steadily. As most important treatment for benign airway stenosis, respiratory intervention has become one of the most common treatments to fight the disease. However, the restenosis caused by tissue hyperplasia, wound repair and scar formation after treatment is still common, which remains the limitation of respiratory intervention. Long-term efficacy of repeated interventional treatment is unsatisfying, too. Several studies have discovered similar mechanism between stenosis of tracheal to hyperplastic scar of skin, both of which are relative with deep structure injury such as the intrinsic layer of airway mucosa. PRP has shown significant efficacy for hyperplastic scar of skin. Correspondingly, PRP will be applied as treatment of refractory benign airway stenosis to reduce restenosis by inhibit the formation of granulation.
To demonstrate that the Conveyor System can safely provide left ventricular access to deliver the SAPIEN 3 (Edwards Lifesciences, Irvine, California) transcatheter heart valve in patients who have been diagnosed with prior mitral valve replacement or repair (failing bioprosthetic mitral valve) who are candidates for mitral valve-in-valve procedure.
