Slipped capital femoral epiphysis represents approximately 10.8 cases per 100,000 children. The primary source for the blood supply of the head of the femur is the deep branch of the medial femoral circumflex artery. Loder described a classification for Slipped capital femoral epiphysis based on ability of the child to walk or not(walking=stable, non-walking=unstable).
Vitiligo is an acquired disorder of the skin and mucous membranes characterized by well circumscribed depigmented macules and patches that occur secondary to selective destruction of melanocytes (Zhang et al., 2009). Generalized vitiligo is the most common clinical presentation and often involves the face and acral regions (Alikhan et al., 2011).
In vitro fertilization(IVF) with Gonadotropin-releasing hormone (GnRH) antagonist is one of the most used protocol for the treatment of infertile couples nowadays. Despite several advantages over GnRH agonist, the antagonist may be associated with a slightly reduction in pregnancy rates. Several medications have been tested in order to increase ovarian response to ovulation induction, including estradiol and testosterone. A clinical trial in women with IVF indication will be performed and this women will be randomly assigned to receive topic testosterone, oral estradiol or no pre-treatment prior to IVF with human Chorionic Gonadotropin (hMG) and GnRH antagonist. The primary endpoint will be the size and number of follicles on the beginning of the cycle, after pre-treatment.
Using double blind, randomized controlled design to study the immediate, short-term and intermediate-term therapeutic effects of ultrasound guided hyaluronic acid injection and hyaluronic acid combined dextrose injection to patients with knee osteoarthritis.
Previous studies have shown that the addition of bevacizumab to the standard first-line platinum-based combination therapy can improve the objective response rate of patients with advanced non-squamous non-small cell lung cancer by 20% to 28% and improve survival. Data from these published literatures suggest that the improvement in objective response rates is due mainly to patients with stable disease of chemotherapy. It has been reported that 15% of patients achieved objective remission after continuing treatment with the regimen after receiving 2 cycles of platinum-based combination chemotherapy. Therefore, the use of 2 cycles of chemotherapy after stabilization of patients with bevacizumab, hoping to improve the objective response rate of such patients 20%, and may improve survival. For the above reasons, design this study to validate our hypothesis.
The objective of this trial is to find out if there is a difference between single-piece and two-piece titanium patient-specific mandibular subperiosteal implants in terms of implant survival, patient satisfaction, and soft tissue dehiscence. This is to enhance both surgical and prosthetic outcomes for the sake of improved implant longevity, soft tissue health and patient well-being.
Background: Neoadjuvant chemoradiotherapy (CRT) and total mesorectum excision (TME) has become the standard therapy for the treatment of locally advanced rectal cancer (LARC) to reduce the local recurrence rate, however, no improvement of distant metastasis rate was observed, and the incidence of postoperative local recurrence and distant metastasis can reach more than 25%. It is still a challenge for us to improve the RO resection rate of locally advanced rectal cancer and reduce the incidence of local recurrence and distant metastasis.
Klebsiella pneumoniae is one of the most common pathogens causing nosocomial infection. Recently, the emergency of Carbapenem-Resistant Klebsiella pneumoniae (CRKP) had cause the clinical therapy be very difficult. However, there is not much empirical data as to the prevalence, risk factors, characteristics, and the rationality of the current therapy for the CRKP infection. Thus, the study was aimed to investigate the epidemiology and risk factors, characteristics, and the rationality of the current therapy for the CRKP infection.
The study is an observational, cross-sectional study aimed at screening and accessing risk factors and complications for Chinese chronic kidney disease (CKD) patients. To investigate the prevalence of hypertension, cardiovascular and cerebrovascular diseases, protein energy malnutrition（PEM）, cognitive impairment and other complications in the CKD patients. To develop biomarkers of CKD.
The study is an observational, multicenter, prospective cohort study aimed at evaluating a 5-year screening programme for chronic kidney disease(CKD) in a population of elderly patients, aged 65 years or more, in China.To analyze the etiology and composition spectrum, the incidence of complications and co-morbidities.To assess the correlation between daily living ability, mental and physical function, quality of life, nutritional status and prognosis.To develop biomarkers of renal aging.
