Objective To improve outpatient medical care. Methods A sample survey was conducted into 1716 outpatients during 6 days in October of 2004 using questionnaires that covered such items as the patients' choice of hospitals, their choice of doctors, their medical needs and their needs for continuous services. Results The medical needs of the patients, regardless of gender, age, and form of payment (personal payment, medical insurance or treatment at public expenses), are, in terms of urgency, disease relief, safety, respect, service, and the right to be informed. Ranking first in the needs for continuous medical services is medical appointments, with telephone follow-ups coming next. Conclusion Outpatients have diversified medical needs and hospitals ought to attach importance to relieving patients from disease, ensuring medical safety, respecting patients, improving services, bettering continuous medical services, and satisfying the needs of patients at different levels.

Object To develop an immunoassay method of species-specific protein for Radix Glycyrrhizae (RG) identification. Methods The crude drug of RG as a model was studied in this paper,the antigen of RG protein (RGP) was screened by Western-blot analysis using anti-RG serum. After species-specific protein,RGP was purified,and rabbit antiserum against RGP was prepared,the rabbit IgG of anti-RGP was isolated and biotinylated,then the sandwich enzyme-linked immuosorbent assay (ELISA) was developed. Results The method was only specific to RG,which was harvested from various areas or species,and showed excellent sensitivity and reproducibility. Conclusion The result suggests that the immunoassay method using specific antigen of RGP as a detection objective be a new potential for the unequivocal identification and quality control of RG.

Objective: To establish a new method for determining residual organic solvent DMF in imiquimod. Methods: The samples were injected into an Agilent HP-PLOT/Q capillary column(30 m × 0. 530 mm,40. 0 μm) by a headspace sampler and ana-lyzed with an FID detector, the carrier gas was nitrogen, the inlet temperature was 250℃, and the detector temperature was 270℃. The column temperature was programmed raised. Results: The resolution among the peaks of DMF and the other residual solvents could meet the requirements. There was a good linearity within the experimental concentration range. The average recovery was 94. 6%(RSD=4. 0%, n=9). The limit of quantification and the limit of detection was 4. 809μg·ml-1 and 0. 963μg·ml-1, respectively. Conclusion:The method is convenient, accurate and sensitive, which can be used in the determination of residual solvent DMF in imi-quimod.
