Method The model of endometriosis rat was induced by transplanting with endometrium surgically The rats were divided into 6 groups randomly： the non-treatment group, the castrate group, Danazol group（80 mg/kg）, ＂Caulis Sargentodoxae Formula＂ group （110 g/kg）, the medium dose group（77.5 g/kg） and the low dose group（55 g/kg）. After 3 weeks＇ treatment, the volume ofendometrium was detected by cutting the rats＇ belly open, drawing the materials from endometrium for tissue section, and doing the quantity analysis of endometrium by semiautomatic image analysis machine.Results There was no significant difference of the endometrium volumes between the low dose group and the non-treatment group（P〉O.05）, other groups＇ endometrium volumes were significantly lower than those of the non-treatment group（P〈0. 05）. And apart from the low dose group, all other groups＇ heights of the endometrium epithelia were significantly lower than that of the non-treatment group（p〈0.01）. Conclusion ＂Caulis Sargentodoxae Formula＂ can refrain the growth of the endometrium, and the effects are better than that of Danazol＇s.展开更多

Methods: A total of 128 UC patients who received treatment in the hospital between January 2013 and April 2017 were collected and divided into control group and observation group by random number table. Control group received conventional oral drug therapy, and the observation group received retention enema by caulis sargentodoxae enema combined with oral drug therapy. Before treatment and after 4 weeks of treatment, the differences in the levels of immunoglobulin and inflammatory response indexes in serum as well as intestinal flora levels in mucosa lesion tissue were compared between the two groups.Results: The differences in levels of immunoglobulin and inflammatory response indexes in serum as well as intestinal flora levels in mucosa lesion tissue were not statistically significant between the two groups of patients before treatment. After 4 weeks of treatment, IgA, IgG, IgM and IL-4 contents in serum as well as bifidobacterium and lactobacillus levels in mucosa lesion tissue of observation group were higher than those of control group while ESR, CRP, IL-6 and TNF-αcontents as well as E. coli level in mucosa lesion tissue were lower than those of control group. Conclusion: Retention enema by caulis sargentodoxae enema combined with oral drugs can effectively optimize the immune inflammatory state and balance the intestinal flora distribution in patients with UC.展开更多
