To clarify the interactions between heavy metals, antibiotics, and humic acid, copper (Cu), oxytetracycline (OTC), norfloxacin (NOR), and humic acid samples from river sediment in the Polder area were selected to build single and coexisting systems. Groups of experiments were designed to investigate the kinetics, thermodynamics, and isotherms of Cu, OTC, and NOR adsorption onto humic acid in single and Cu+OTC and Cu+NOR coexisting systems (concentration ratio=1:1). The physicochemical properties of humic acid were analyzed by scanning electron microscopy (SEM), X-ray diffraction (XRD), BET tests, and IR spectroscopy, and the possible adsorption mechanisms are discussed.

Objective: To research the diagnostic performance of clinical potential bone turnover indexes in rheumatoid arthritis (RA) complicated with osteoporosis (OP).

Methods: This study involved 87 RA patients, 48 with OP, and 39 without OP, and 204 non-RA control patients, including those with systemic lupus erythematosus, ankylosing spondylitis, primary Sjogren's syndrome, systemic sclerosis, and healthy patients. The levels of 25-hydroxyvitamin D [25(OH)D], β-crosslaps (β-CROSSL), parathyroid hormone (PTH) were measured by electrochemiluminescence (ECLIA), and the level of bone alkaline phosphatase (BALP) was measured by lectin affinity method.

Objective: To investigate methods and therapeutic effects of sequential drugs treatment for central pain following spinal cord injury.

Methods: A total of 28 patients suffered from central pain following spinal cord injury were treated with sequential drugs from 1994 to 2008, including 23 males and 5 females, ranging in age from 25 to 59 years (mean 42 years). According to the patients' response to drugs, the therapy grade was adjusted step by step until the pain was relieved.

Overexpression of NorA, an endogenous efflux transporter of Staphylococcus aureus, confers resistance to certain fluoroquinolone antimicrobials and diverse other substrates. The norA gene was amplified by PCR and cloned in the expression vector pTrcHis2. Histidine-tagged NorA (NorA-His) was overexpressed in Escherichia coli cells to prepare two experimental systems, everted membrane vesicles enriched with NorA-His and proteoliposomes reconstituted with purified NorA-His.
