Dietary supplements during the cold season increase rumen microbial abundance and improve rumen epithelium development in Tibetan sheep.

Livestock on the Qinghai-Tibetan Plateau are faced with extreme harsh winters and are often in negative energy balance during this period. Dietary supplementation can improve growth performance of Tibetan sheep and, consequently, we hypothesized that it would also increase microbial abundance and rumen epithelium development. To test this hypothesis, we examined the effect of feed supplementation during the cold season on rumen microbes, fermentation, epithelium development, and absorptive capability in Tibetan sheep.

Efficacy and safety of the combined oral contraceptive ethinylestradiol/drospirenone (Yasmin) in healthy Chinese women: a randomized, open-label, controlled, multicentre trial.

To evaluate and compare the contraceptive efficacy, bleeding pattern, side effects and other positive effects of a combined oral contraceptive (COC) containing drospirenone (DRSP) [Yasmin] with those of a COC containing desogestrel (DSG) in healthy Chinese women. This was a randomized, open-label, controlled, multicentre study of 768 healthy Chinese women requiring contraception. The subjects were randomized to ethinylestradiol (EE) 30 microg/DRSP 3 mg (n = 573) or EE 30 microg/ DSG 150 microg (n = 195), at a ratio of 3 : 1.

Conception probabilities at different days of menstrual cycle in Chinese women.

Objective: To investigate the conception probability among Chinese women.

Design: Prospective observational study.

Setting: Clinics in hospitals and family planning institutes in 10 provinces and cities.

[Efficacy and safety of drospirenone-ethinylestradiol on contraception in healthy Chinese women: a multicenter randomized controlled trial].

Objective: To evaluate the contraception efficacy, mode of bleeding, side effects and other positive effects of drospirenone-ethinylestradiol (Yasmin) in healthy Chinese women.

Methods: This was a multicenter, randomized, control study of 768 healthy Chinese women who consulted about contraception. The subjects were randomized into Yasmin group (30 microg ethinylestradiol plus 3 mg drospirenone, 573 cases) or desogestrel group (30 microg ethinylestradiol plus 150 microg desogestrel, 195 cases) with the ratio of 3:1.
