The purpose of this study is to evaluate the safety, tolerability and efficacy of repeated inhalative doses of Bimosiamose on ozone induced sputum neutrophilia in healthy subjects.
The investigators think that the health care workers who contact frequently with active tuberculosis patients have more increased prevalence of LTBI compared with those who don't.
The purpose of this study is to study the positioning and stabilization of different cardiac walls performed during off-pump coronary artery bypass grafting (CABG) may have dissimilar impact on hemodynamics. The objective is to evaluate hemodynamics during distal coronary anastomoses in different cardiac walls.
This is a randomized, controlled study to compare Short-term ketogenic diet with conventional long-term trial in refractory infantile spasms.
Inflammation may play a role in the development of polycystic ovary syndrome (PCOS). In this study, the investigators investigated the expression of different mediators of inflammation in fatty tissue and in blood in women with and without PCOS.
The aim of this study was to measure the oxygen consumption and peak heart rate achieved during Modified Rivermead Mobility Index (MRMI) assessment in age-matched, healthy and stroke patients, and assess the efficacy of the MRMI tasks for aerobic training in patients with stroke.
Objective: The purpose of this study is to evaluate the application of computer-assisted navigation in Total Knee Arthroplasty (TKA ) by comparing it with conventional TKA. Methods: Gemini MK II implants (Link, Germany) were used. VectorVisionâ CT-free navigation system (BrainLab, Germany) was employed for the TKA. For each subject, computer-navigation TKA and the conventional TKA were separately performed on two knee joints. The operative method and order of the operations were decided on a randomized basis. All the patients and doctors conducting follow-up study and performing imaging measurement were blind to selection of the operation. Student t test was used for statistical analysis. hypothesis: computer-assisted navigation system can significantly improve the accuracy of tibial and femoral cuts on coronal and sagittal planes.
According the terminology of Bethesda 2001, the unsatisfactory cervical cytology can be categorized into specimen rejected, or specimen processed and examined, but unsatisfactory for evaluation of epithelial abnormality. Most of the unsatisfactory cervical cytology was due to scanty epithelial cells, which was defined by less than an estimated 8,000 to 12,000 well-visualized squamous cells for conventional smears. Follow-up of unsatisfactory smear found an increased rate of cervical preinvasive and invasive lesions. Thus, an unsatisfactory smear deserves careful follow-up and studies. Although the Bethesda system allows criteria modification in cases of hysterectomy, pelvic irradiation therapy, or chemotherapy, no studies investigated the clinical factors related to the incidence of unsatisfactory smear. Thus, the investigators designed this trial to study the clinical factors relating to unsatisfactory cervicovaginal smear.The list of patients who received Papanicolaou smear between March 2006 and August 2006 in our hospital will be obtained from the Pathological Department first. Then the investigators will review the medical records from HIS system and pathologic files of these patients. On estimation, 7,437 cases will be enrolled for analysis. Clinical parameters for analysis include: age, gravidity, parity, abortion, menopause, location of Pap smear, history of pelvic malignancy, pelvic irradiation, cervical conization, hysterectomy; at pregnancy; three months postpartum; vaginal bleeding, vaginal abnormal discharge, intrauterine device, and cervical polyp found during pelvic examinations. Patients who missed any of above data will be excluded for analysis. The investigators will use univariate and multivariate analysis for data processing and statistic analysis to find out the relationship between clinical parameters and unsatisfactory cervicovaginal Pap smears.
To investigate whether extravascular lung water index (EVLI) is an independent predictor for multiorgan dysfunction syndrome (MODS) in patients with severe sepsis and to determine if increased EVLI may serve as an predictor for MODS and mortality in those patients.
A randomized, double-blind, placebo-controlled parallel-group study, comparing the bioequivalence of triamcinolone acetonide aqueous nasal spray (Apotex, Inc.) to that of Nasacort® AQ nasal spray (Sanofi-Aventis Pharmaceutical Products, Inc.) in the treatment of seasonal allergic rhinitis.
