OBJECTIVETo evaluate the therapeutic effect of Liujunzi decoction combined with Zuojin pills in treating the radioactive duodenitis and their mechanism, and compare with clinical routine acid suppressants combined with mucous membrane protective preparations to study the mechanism of their efficacy.

METHODAccording to the study of Williams J P and characteristics of duodenitis, and by reference to the radiation enteritis modeling standard, we took the lead in establishing the mouse radioactive duodenal injury model. The model mice were randomly divided into the control group (n = 26), traditional Chinese medicine (TCM) group (n = 16) and the western medicine (oral administration with famotidine 0.5 mL + almagate suspension 0.3 mL per mouse, once a day) group (n = 16). After the standard administrating, such objective indexes as general condition, weight, changes in health score, pathology and expression of inflammatory factors were observed to evaluate the efficacy.

RESULTThe radioactive duodenitis model of mice was successfully established with 12 Gy. Mice in the control group suffered from weight loss, anorexia, low fluid intake, loose stools, and occasionally mucous bloody stool, poor spirit, dim fur, lack of exercise and arch back. Mice in drug intervention groups were generally better than those in the pure irradiation group. The IL-6, IL-1beta, TNF-alpha mRNA expressions in spleen and mesenteric lymph node tissues in TCM and western medicine groups showed a declining trend compared with the control group. Their concentrations in peripheral blood serum also slightly changed. The TCM group revealed notable advantage in reducing inflammatory factors. The microscopic observation showed that a better mucosa repair in intervention groups than the pure irradiation group. The improved Chiu's scoring method showed a statistical significance in the difference between TCM and western medicine groups (P < 0.05).

CONCLUSIONLiujunzi decoction combined with Zuojin pills could treat acute radiation enteritis, regulate organic immunity, and inhibit acute injury, promote local tissue repair, with the potential to resist such adverse effects as radiation intestinal fibrosis. The regulation of inflammatory factor release is one of efficacy generation mechanisms.

Chinese medicinal authentication is fundamental for the standardization and globalization of Chinese medicine. The discipline of authentication addresses difficult issues that have remained unresolved for thousands of years, and is essential for preserving safety. Chinese medicinal authentication has both scientific and traditional cultural connotations; the use of scientific methods to elucidate traditional experience-based differentiation carries the legacy of Chinese medicine forward, and offers immediate practical significance and long-term scientific value. In this paper, a path of inheritance and innovation is explored through the scientific exposition of Chinese medicinal authentication, featuring a review of specialized publications, the establishment of a Chinese medicine specimen center and Chinese medicinal image databases, the expansion of authentication technologies, and the formation of a cultural project dedicated to the Compedium of Materia Medica.
