ABSTRACT
Objective To study the different drying technology.on Wudang Lonicerae Flos (Ⅰ) in chlorogenic acid content.Methods Using HPLC method to research the difference in the contents of chlorogenic acid of Wudang Lonicerae Flos (Ⅰ) employing oven-drying method,air-dried method and steamed drying technologies.DIONEX C18 (4.6 mm×250 mm,5 μm) was used.The mobile phases consisted of acetonitrile-0.4％ phosphoric acid aqueous solution (17 ∶ 83).The detection wavelengths of chlorogenic acid was 327nm.The flow rate was 0.4 ml/min.The column temperature was 30 ℃.Results The Separation of Chlorogenic acid content was satisfactory.The concentration and peak area showed a good linearity relationship with the range of 0.285-2.850 μg.Precision,repeatability and stability met the requirements.The average recovery was 100.26％ with RSD 1.95％.Chlorogenic acid content in the steamed drying Wudang Honeysuckle (Ⅰ) was higher.Conclusions The method of steam drying is better than that of oven-drying method and drying.
ABSTRACT
Objective To understand the knowledge of tuberculosis in general hospital patients with respiratory diseases.Methods Face to face questionnaire survey 821 respiratory patients, the main contents include: the tuberculosis awareness, common symptoms of tuberculosis, tuberculosis with or without contagious, persistent cough expectorant willing to go to where the treatment of tuberculosis, national policy, treatment of the course of treatment, tuberculosis prevention measures, and whether the knowledge of tuberculosis drug resistance.Results 92.1% of patients were aware of TB and 98.7% of patients knew TB was contagious, and 99% knew that TB was transmitted by the respiratory tract.Only 4.5% of patients with symptoms appear willing to go to tuberculosis treatment of patients.94.9% of the patients were aware of a specific TB control facility, 85% knew that the basic TB treatment was free, 99% thought to be good treatment of tuberculosis patients, 55% of patients know that tuberculosis treatment for a long time, to regular medication.30% of people know that mycobacterium tuberculosis resistance.90% of patients know to isolate tuberculosis patients, 40% of patients that protect susceptible populations, and 95% believed that BCG could prevent tuberculosis.Conclusion Patients have a certain understanding of tuberculosis, the timely treatment of indifference to the treatment of treatment is probably not impressed, very little knowledge of tuberculosis resistance.
