Objective To explore the safety of fluoreuracil implanting to abdominal cavity during operation of advanced colonic cancer patients, search for new approach for preventing from local relapse of colonic cancer. Methods Divide 60 patients accepting radical colonic cancer surgery into 2 groups, treating group and control group. Treating group are implanted of fluorouracil along the wounded surface of tumor and draining path of lymph nodes. To observe the curing of wounded surface, stomal leak ,wound infection, intestinal obstruction and hospital day. Results There is no significant differences between treating group and control group in stomal leak,wound infection, intestinal obstruction and hospital day (P>0.05). Conclusion It is safe to implant fluoruuracil during radical colonic surgery, which is an effective path of regional chemotherapy after operation.

Oleanolic acid (OA) is a pentacyclic triterpenoid compound extracted from olea europaeal, a traditional Chinese medicine herb. OA has been used in the clinic as a hepatoprotective medicine in China since 1970s. In our previous study, we observed that OA could ameliorate hyperlipidemia in animal models. In the present study, we conducted a small-scale clinical trial to evaluate the hypolipidemia effect of OA in hyperlipidemic patients. Hyperlipidemic patients were administrated with OA for four weeks (4 tablets once, three times a day). The blood samples of the patients were collected before and after OA treatment. The biological parameters were measured. Furthermore, three patients' blood samples were studied with DNA microarray. After OA administration, the TC, TG, and HDLC levels in serum decreased significantly. DNA microarray analysis results showed that the expressions of 21 mRNAs were significantly changed after OA treatment. Bioinformatics analysis showed 17 mRNAs were up-regulated and 4 mRNAs were down-regulated significantly after OA treatment. Five mRNAs (CACNA1B, FCN, STEAP3, AMPH, and NR6A1) were selected to validate the expression levels by qRT-PCR. Therefore, OA administration differentially regulated the expression of genes involved in lipid metabolism. The data showed a clinical evidence that OA could improve hyperlipidemia and also unveiled a new insight into the molecular mechanisms underlying the pharmacological effect of OA on hyperlipidemia.
