Association of immunophenotypic characterization of peripheral lymphocytes with different clinical phenotypes of tuberculosis in Chinese Han children.
Very few researchers have studied the changes in peripheral lymphocyte patterns in adult tuberculosis (TB) and even less researches have been conducted in pediatric TB. In this study, we obtained blood samples from 114 Chinese pediatric TB patients and 116 matched controls to study the association of phenotypic subsets of peripheral lymphocytes with different clinical phenotypes of TB. ⋯ This study demonstrates changes in the lymhocyte distribution in children suffering from different clinical phenotypes of TB; such as primary pulmonary TB, and TB meningitis. These patterns may have significance in understanding the pathogenesis and prognostic markers of the disease, and for developing immunomodulatory modalities of therapy.

Comparison of glycemic variability and glycated hemoglobin as risk factors of coronary artery disease in patients with undiagnosed diabetes.
The role of chronic hyperglycaemia as a coronary artery disease (CAD) risk factor is well-known, and the glycemic variability is still a matter of debate. The aim of this study was to investigate the association of admission glycemic excursion and hemoglobin A(1c) (HbA(1c)) with the presence and severity of CAD in patients with undiagnosed diabetes mellitus (DM). ⋯ Both admission glycemic excursion and chronic hyperglycaemia are associated with the severity of CAD in newly diagnosed DM patients. MAGE displays a significant value in predicting CAD in patients with undiagnosed diabetes even more than HbA(1c).

Roles of preoperative arterial blood gas tests in the surgical treatment of scoliosis with moderate or severe pulmonary dysfunction.
It has been stated that preoperative pulmonary function tests are essential to assess the surgical risk in patients with scoliosis. Arterial blood gas tests have also been used to evaluate pulmonary function before scoliotic surgery. However, few studies have been reported. The aim of this study was to investigate the roles of preoperative arterial blood gas tests in the surgical treatment of scoliosis with moderate or severe pulmonary dysfunction. ⋯ No significant correlation between the results of the preoperative arterial blood gas tests and postoperative pulmonary complications existed in scoliotic patients with moderate or severe pulmonary dysfunction. However, the postoperative complications tended to increase with the decrease of partial pressure of arterial oxygen in the arterial blood gas tests.

Pure alumina bearings with cementless stems versus sandwich bearings with cemented stems in total hip arthroplasty.
Ceramic bearing surfaces have been introduced to prevent osteolysis after total hip arthroplasty (THA), but little is known about the difference in clinical and radiological results between pure alumina and sandwich alumina bearings. The purpose of this study was to analyze the results obtained with third-generation alumina-on-alumina THA with two different designs both in liner and femoral stem fixation after a minimum follow-up of 4.2 years. ⋯ The sandwich design of the acetabular bearings can not reduce the migration rate in ceramic bearings but increase the liner fracture rate compared to pure ceramic liners. The high loosening rate in fluted and taped designed cemented stems with sandwich liners warrant caution to their use.

Prospective study of first night effect on 2-night polysomnographic parameters in adult Chinese snorers with suspected obstructive sleep apnea hypopnea syndrome.
A prospective 2-night polysomnographic (PSG) study in Chinese snorers was designed to assess the role of the first night effect (FNE) in PSG parameters and the diagnosis of obstructive sleep apnea hypopnea syndrome (OSAHS). ⋯ Only mild FNE can be found on two consecutive nights of PSG in adult Chinese snorers, but it has no effect on the diagnosis of OSAHS. A single polysomnographic night may be adequate for the diagnosis of OSAHS.
