Clinical Observation of Paclitaxel or 5-Fluorouracil Combined with Nadaplatin in the Treatment of Ad-vanced Nasopharyngeal Carcinoma / 中国药房

OBJECTIVE:To observe clinical efficacy and safety of paclitaxel or 5-fluorouracil combined with nadaplatin in the treatment of advanced nasopharyngeal carcinoma(NPC). METHODS:42 patients with advanced NPC were randomly divided into observation group and control group(n=21). 2 groups of patients were treated with radiotherapy. Observation group received che-motherapy of paclitaxel(135 mg/m2,d1)and nedaplatin(80 mg/m2,d 2-4);control group received chemotherapy of 5-fluoroura-cil(500 mg/m2,d1-5)and nedaplatin(80 mg/m2,d1-3);a treatment course lasted for 3 weeks,and both groups received 2 courses of treatment. Clinical efficacy, survival rate and ADR were observed in 2 groups. RESULTS:The overall response rate was 95.2%in observation group and 90.5% in control group,with no significant difference between 2 groups (P>0.05). The 3-year overall survival rate and progression-free survival rate were 81.0% and 71.4% in observation group and 76.2% and 66.6% in control group,with no significant difference(P>0.05). The incidence of nausea and vomiting in observation group were lower than in con-trol group,while the incidence of oral mucosa inflammation was higher than control group,with statistical significance(P<0.05). CONCLUSIONS:The chemoradiotherapy of paclitaxel or 5-fluorouracil combined with nadaplatin have similar therapeutic efficacy for advanced NPC. ADR by chemoradiotherapy should be monitored closely and treated timely.

Determination of Ginsenoside Rg1, Ginsenoside Re and Ginsenoside Rb1 in Yi’ nianjin by UPLC / 中国药师

Objective:To establish a UPLC method for the determination of ginsenoside Rg1 , ginsenoside Re and ginsenoside Rb1 in Yi’ nianjin. Methods: The column was ZORBAX Eclipse Plus C18 (2. 1 mm × 50 mm,1. 8 μm), the flow rate was 0. 21 ml· min-1 , the column temperature was 30℃, the mobile phase consisted of acetonitrile-water with gradient elution, the detection wave-length was 203nm, and the sample size was 1μl. Results:The linear range of ginsenoside Rg1 was 0. 020 3-0. 303 9 mg·ml-1 ( r=0. 999 6), and the average recovery was 99. 05% (RSD=1. 3%, n=6). The linear range of ginsenoside Re was 0. 020 2-0. 302 7 mg·ml-1(r=0. 999 8), and the average recovery was 101. 31% (RSD=1. 1%, n=6). The linear range of ginsenoside Rb1 was 0. 020 3-0. 305 1 mg·ml-1(r=0. 999 8), and the average recovery of 100. 71% (RSD=0. 9%, n=6). Conclusion: The method is simple and accurate, and can determine the three components simultaneously. The method can be used in the quality control of Yi’ nianjin.

Consumption of Narcotic Analgesics in Eight Hospitals of Lianyungang in 2003～2005 / 中国药房

OBJECTIVE:To evaluate the use of narcotic analgesics in eight hospitals of Lianyungang,Jiangsu Province. METHODS:Consumption of narcotic analgesics in eight hospitals of Lianyungang was audited and analyzed in terms of variety,volume,sales value and DDDs.RESULTS:Narcotic analgesics as used in the eight hospitals of Lianyungang recorded year-on-year growths in both consumption volume and sales value,with their growth rates in sales value being significantly higher than those of other drugs.Consumption of Pethidine hydrochloride was on the down while that of Morphine was picking up year-on-year.The DDDs of Fentanyl patch remained small.CONCLUSIONS:The use of narcotic analgesics in the eight hospitals of Lianyungang tends to be rational in recent years.
