OBJECTIVETo assess the clinical effect of integrative Chinese and Western medicine in treating nontumorous vulval intraepithelial lesion (NIEL).METHODSOne hundred patients of NIEL, with their diagnosis confirmed by pathologic examination, were equally assigned to two groups randomly, the treatment group and the control group. The treatment group was treated by Chinese recipe consisting of herbs for nourishing Gan-Shen, it was decocted for 3 times, the foregoing two decoctions for oral intake, and the latter one (500 mL) for hip bathing 5-10 min every night before sleep. Besides, the self-formulated preparation Jingan oil (composed of aureomycin and glycerine, etc. ), was locally applied twice every day. The control group was treated only by local applying of Jingan oil and a 5-10 min hip bathing with warm water every night. The course for both groups was 2 months. Efficacy of the treatment was assessed at the end of the therapeutic course and after a 2-month follow-up, depending on the changes of local lesion degree, vulval symptoms as pain and itching, estrogen and progestin receptors in the lesion, and the scores of symptoms.RESULTSThe total clinical effective rate was 94% (47/50) in the treatment group and 66% (33/50) in the control group. The severity of local lesion degree, symptoms of pain and itching and the scores of symptoms were significantly improved in both groups, as compared with those before treatment (all P <0.01). However, comparison between groups showed that the improvement was better in the treatment group. The positive rates of estrogen and progestin receptors in the local lesions of the two groups showed insignificantly statistical difference.CONCLUSIONThe integrative medical treatment can effectively alleviate the NIEL and improve the relevant clinical symptoms.
