Objective To explore the effects of nursing intervention on medication compliance of patients with ankylosing spondylitis (AS). Methods 92 patients with AS in the department of rheumatology and immunology of our hospital from January 2005 to December 2006 were randomized into the control group (45 cases) and the observation group (47 cases). The control group was given routine nursing and health education. While the observation group was given comprehensive nursing intervention based upon routine nursing and health education. The knowledge level about AS, medication compliance and relapse rate were compared between the two groups by adopting questionnaires. Results The knowledge level about AS, medication compliance, and relapse rate in the observation group were better than those in the control group (P<0.05). Conclusions Positive nursing intervention could improve the health knowledge level, ameliorate recognition and attitude and delinquent conduct, strengthen their medication compliance. It could control the process of illness, decrease the relapse rate and disable rate so that it could improve the life quality of patients.

Objective To investigate the inactivating effect of heat and ultraviolet(UV) light on HCV JFH-1 strain using the cell culture system. Methods The HCV JFH-1 virus stock, with an initial titer of 2.5 × 104 FFU/ml, was exposed in 56℃ water bath or to UV light for varying durations of time for explo-ring their inactivating effects on the virus. The kinetics of virus titer reduction was determined by an indirect immuno-fluorescence assay (IFA). If the cells infected with the exposed virus stock were IFA negative after three blind passages, the virus stock was considered to be inactivated completely. Results After incubation of the HCV JFH-1 virus stock (2.5 × 104 FFU/ml)in 56℃ water bath for 10 min, 20 min and 30 min, the virus titers were reduced to 1.6 × 103 FFU/ml, 3.1 × 102 FFU/ml and 3.3 × 10 FFU/ml, respectively. The exposure of the virus stock to UV light (wavelength 253.7 nm, intensity ≥60 μW/cm2, 30 cm below the UV lamp) for 15 s, 30 s and 45 s resulted in virus fiter reduction to 1.0 × 103 FFU/ml, 1.1 × 102 FFU/ml and 2.7 × 10 FFU/ml, respectively. After 40 min incubation of the virus stock at 56℃, or 1 min exposure to UV light (wavelength 253.7 nm, intensity ≥60 μW/cm2) the virus infectious titer was reduced below the detection limit of IFA, and the IFA was still negative even after three blind passages, indicating that the virus was inactivated completely. Conclusion HCV is sensitive to heat and UV light treatment. For HCV JFH-1 virus stock containing 2.5 × 104 FFU/ml virus, heat treatment at 56℃ for 40 min, or UV light expo-sure at an intensity of ≥60 μW/cm2 for 1 min, resulting in complete virus inactivation.

A highly sensitive electrochemical deoxyribonucleic acid(DNA) biosensor based on multi-walled carbon nanotubes(MWNT)/Ag-TiO_2 composite film was developed. The solution containing Ag-TiO_2-MWNT composite was casted on the carbon paste electrode surface to form a robust film, which combine the advantages of the good biocompatibility of Ag-TiO_2 naocomposite and the fine conductivity, as well as the large active surface area of carbon nanotubes. The composite could greatly improve the immobilization capacity of the probe DNA. The morphologies and electrochemistry of the nanocomposite film were investigated by scanning electron microscopy and electrochemical techniques including electrochemical impedance spectroscopy and cyclic voltammetry, respectively. DNA hybridization events were monitored by a label-free method of electrochemical impedance spectroscopy. This label-free electrochemical impedance DNA biosensor showed high sensitivity and selectivity for phosphinothricin acetyltransferase gene sequence assay. The multicomponents films also displayed a high stability during repeated regeneration and hybridization process.
