OBJECTIVEThe effect of Kou Yan Qing Ke Li on the prevention and treatment of radiation-induced oral mucositis was investigated in patients with nasopharyngeal carcinoma.

METHODSSixty patients with nasopharyngeal carcinoma to be treated with radiotherapy were randomized into two groups: the experimental and control groups. The experimental group (30 patients) was treated with Kou Yan Qing Ke Li during the full course of radiotherapy. The control group (30 patients) rinsed their mouths in the same way with mouth washes containing 0.9% sodium chloride injection, lidocaine, dexamethasone, vitamin B2 and B2 gargle liquid mixture, when grade 2 and above radiation-induced oral mucositis appeared in the process of radiation. Radiation-induced oral mucositis was assessed according to the radiation therapy oncology group criteria. The time of occurrence and degree of pain grade were compared between the two groups.

RESULTSThe first onset of oral mucositis in the experimental group (12.40 d ± 2.74 d) was later than that in the control group (9.46 d ± 1.39 d) (t = 5.241, P < 0.001), whereas the grade of pain and acute radiation mucositis was lower in the experimental group than that in the control group. The difference was statistically significant.

CONCLUSIONKou Yan Qing Ke Li could delay the time of occurrence of radiation-induced oral mucositis, reduce the severity of radiation stomatitis, alleviate the pain of patients, improve the clinical symptoms of patients, and effectively prevent and treat radiation-induced oral mucositis in patients with nasopharyngeal carcinoma.

This paper is aim to investigate the pharmacokinetics and absolute bioavailability of neoline in Beagle dogs, and provide a theoretical basis for further study. Ethyl acetate was used for liquid-liquid extracting after 10% ammonia alkalizing. The method of UPLC-Q-TOF-MS was established for the determination of neoline plasma concentrations. Beagle dogs were orally or intravenously administered with neoline for pharmacokinetic and absolute bioavailability study. Good linear relationship of neoline was found over the range of 0.1-4 mg x L(-1) (R2 = 0.9982) and 2-100 microg x L(-1) (R2 = 0.9945). Intra-and inter-day precision, expressed as the relativestandard (RSD) were less than 5.0%. Accuracy, expressed as the relative error (RE) was within 90.0%-115%. The recovery of neoline in dog plasma was more than 80%. After 6 mg x kg(-1) for ig and 1 mg x kg(-1) for iv administration of neoline, the main pharmacokinetic parameters were analyzed with Winnonlin software. t(1/2) were (313.88 +/- 63.18), (236.33 +/- 229.84) min, and AUC(0-infinity) were (58,027.40 +/- 14,132.69), (473,578.02 +/- 82,333.08) min x microg x L(-1) for ig and iv administration respectively. The absolute bioavail ability was (73.15 +/- 10.29) %. The method of UPLC-Q-TOF-MS described in the report was sensitive, reliable and specific, and suitable for pharmacokinetic study of neoline in Beagle dog. The high absolute bioavailability of neoline in dog suggested good absorption of neline which was worth of further investigation.
