METHODS： Forty-eight BALB/c mice were random-ly divided into two groups in the ratio of I ： 3, 12 in one group and 36 in the other. The 12-mouse group was the control group that was intragastrical- ly administered physiological saline for 3 weeks. The 36 mice in the other group were given 30 mg- kg ·^-1 d i GRT for 3 weeks, then randomly divided into 3 subgroups： the model group, GRI group and Roucongrong （Herba Cistanches Deserticolae） group, with 12 mice in each group. In the model group, 0.25 mL physiological saline was intragastri- cally administered; in the GRT group, GRT, 0.25 mL at 30 mg · kg ^-1· d ^-1 was intragastrically adminis- tered once a day; in the Roucongrong （Herba Cis- tanches Deserticolae） group, mice were adminis- tered Roucongrong （Herba Cistanches Deserticolae） decoction equivalent to 0.25 mL at a final dose of 10g.kg 1.d.1 crude drug （calculated as per 20 times of 0.5 g· kg^-1. d ^-1 for adults）, and GRT 0.25 mL at 30 mg- kg^-1· d^- 1 daily. After another 3 weeks of exposure, expression levels of the reproduction-re- lated genes DEAD （Asp-Glu-Ala-Asp） box polypep- tide 3, Y-linked, B-cell CLL/lymphoma 6 and Signal transducer and activator of transcription 3 were evaluated. RESULTS： After 6 weeks of GRT treatment, the sper- matogenic cell population in the convoluted tu- bule of testis was in disorder and the tubule cavity expanded. Sertoli cell and Leydig cells exhibited at- rophy or disappeared. The number of sperm de- creased. The spermatogenic cell level of testis for male mice was ranked in order and sperm was pro- duced in the cavity of the spermatogenic cell. The expression levels of DDX3Y, BCL6 and STAT3 were up-regulated.CONCLUSION： GRT affected reproduction-related genes. Roucongrong （Herba Cistanches Desertico- lae） reversed reproductive toxicity in mice induced by GRT.展开更多

The 114 patients ot the test groupwere treated with oral sustained release tablets of Tripterygium Wiltordii (TW-SR) , 2 tablets twice a day for4 weeks, 112 patients of the control group received tablets of Tripterygium Wiltordii(TW) orally 2 tablets 3times per day for 4 weeks. Testing results showed thetotal effective rates of the two groups were 92 . 11%and 90. 65 % , respectively (P >0. 05) . The adverse reaction rate of TW-SR was 20 . 18% , which was low-er than that of TW group of 70. 54% (P < 0. 01 ) . Results of pre-clinical pharmacologic experimental studydemonstrated that TW-SR has obvious anti-inflammatory , analgesic and immunosuppressive actions the sameas TW, while the toxicity of TW-SR was less than that of TW significantly.展开更多
