Objective:To confirm the potential of growth-related gene productβ(GROβ) as a biomarker for colorectal cancer. Methods:Serum GROβlevels in 123 subjects with colorectal cancer, 88 healthy controls, and 125 subjects with other diseases were measured using enzyme-linked immunosorbent assay. Serum levels of carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) in all subjects were measured using immunoluminometric assay. Statistical analyses were conducted to determine the associa-tions between serum GROβlevels and clinical parameters for colorectal cancer. The receiver operating characteristic (ROC) curves of GROβ, CEA, and CA19-9 were analyzed. Results:The serum GROβlevels were higher in patients with colorectal cancer (median=96.15 pg/mL) than in the healthy controls (median=43.28 pg/mL, P<0.01) and in patients with other diseases (median=57.30 pg/mL, P<0.01). The serum GROβlevels in patients with colorectal cancer were positively correlated with the tumor-node-metastasis staging (P<0.01) and depth of infiltration (P<0.05), but not with the histological grade, tumor embolus, lymph node metastasis, gross pathologic tu-mor type, or gender of the patients. The sensitivity and specificity of the assay for serum GROβwere 56.1%(69/123) and 95.31%(203/213), respectively. The diagnostic sensitivity was 22.2%(4/18) for stage I and 66.7%(26/39) for stage II when the data of GROβwere combined with the data of CEA and CA19-9. The ROC curve constructed with the data of GROβ(0.834) was larger than that construct-ed with the data of CEA (0.739) or CA19-9 (0.676) for discriminating colorectal cancer from the matched controls. Conclusion:These preliminary results indicated that the serum GROβlevel could be a useful biomarker for colorectal cancer diagnoses.

OBJECTIVE:To study the rational use of antibacterials in inpatients.METHODS:A discussion was made on the use of antibacterials for 4 948 inpatients in 2004 and 5 476 inpatients in 2005 in our hospital,managed in accordance with the requirements for hospital management by level and the Guidelines for Clinical Use of Antibacterials.RESULTS & CONCL- USIONS:The inpatient use of antibacterials in our hospital has been made basically rational through implementation of systematic management,enactment of antibacterials management by level,monitoring on usage of antibacterials and enforcement of warning system for overusing.
