Effects of metabolic abnormalities, hyperandrogenemia and clomiphene on liver function parameters among Chinese women with polycystic ovary syndrome: results from a randomized controlled trial.

PURPOSE: To investigate the effects of metabolic abnormalities, hyperandrogenemia and ovulation induction by clomiphene/acupuncture on liver function parameters among women with polycystic ovary syndrome (PCOS). METHODS: This is a secondary analysis of a randomized controlled trial. All 1000 subjects were diagnosed as PCOS by modified Rotterdam criteria. Liver function parameters, metabolic panel and hormone profile were measured at baseline and after treatment. The relationship between liver parameters with metabolic, hormonal parameters and ovulation induction was examined. RESULTS: PCOS women with metabolic syndrome had higher liver enzyme levels but lower bilirubin and bile acid levels than without. PCOS women with hyperandrogenemia had higher liver enzyme, bilirubin levels than without. Correlation analyses showed that worsening of metabolic parameters was associated with higher liver enzyme levels but lower bilirubin and bile acid levels, while increased androgen levels were associated with higher liver enzyme, bilirubin and bile acid levels. Ovulation induction with clomiphene citrate could decrease bilirubin and bile acid levels, while acupuncture had no obvious effect on liver function. CONCLUSIONS: Among PCOS women, metabolic abnormalities and hyperandrogenemia impaired different liver function parameters. Clomiphene could decrease the bilirubin and bile acid levels while acupuncture had no obvious effect on liver function.

Effects of Sophy ß-glucan on growth performance, carcass traits, meat composition, and immunological responses of Peking ducks.

The response of Peking ducks to supplements of Sophy ß-glucan was studied. A total of 160 healthy 1-d-old mixed-sex ducklings were randomly allocated to 3 groups: Sophy ß-glucan (n = 80), bacitracin zinc (n = 40), and control (n = 40), which received the same antibiotics-deficient diet supplemented with 1% ß-glucan, 5% bacitracin zinc, or nothing, respectively. During 2 mo of the study, growth performance, carcass composition, and meat quality of Peking ducks were evaluated. Additionally, a separate immunological study was conducted with a total of 105 healthy male Peking ducks in 7 groups (n = 15) and immunized with different doses of ß-glucan (0, 0.5, 2.5, 12.5, and 62.5 µg/duck) and BSA (200 µg/duck). Blood was taken for detection of anti-BSA-IgG antibody and peripheral blood mononuclear cells proliferation assays. Groups subjected to different dietary treatments showed almost no differences in growth performance and slaughter traits except breast muscle percentage and intestinal length. These 2 indicators were significantly higher in the bacitracin zinc group than in the control and ß-glucan groups (P < 0.05). Similarly, chemical compositions, fatty acids, and amino acids of breast muscle were not significantly influenced by the diet. Ducks immunized with Sophy ß-glucan did not have enhanced level of anti-BSA-IgG antibodies but had significant peripheral blood mononuclear cells proliferation compared with unchallenged ducks (P < 0.01). With an increase in the glucan concentration, the proliferative responses approximately linearly increased. These findings indicate that 1% Sophy glucan did not improve duck growth performance, carcass composition, and meat quality significantly under the conditions of the present experiment and mainly had regulatory or enhancing properties on poultry nonspecific cellular immunity.

Analysis of fibronectin, fibronectin receptor and interleukin-1 in patients with cirrhosis treated by the Yanggan Jieyu decoction.

AIM: To investigate the effects of the Yanggan Jieyu (YGJY, nourishing the liver and alleviating mental depression) decoction on the plasma concentrations of fibronectin (FN), fibronectin receptor (FNR), tumor necrosis factor alpha (TNF-α), and the activity of interleukin-1 (IL-1) in patients with cirrhosis. METHODS: Thirty-four cases of decompensated cirrhosis were divided into the YGJY decoction treatment group and the control group (patients received standard treatment). FN, FNR and TNF-α were measured by ELISA and expressed as mg/L (FN, FNR) and ng/L (TNF-α). IL-1 was measured by mice thymocyte proliferation using a ß scintillation counter and was expressed as cpm. RESULTS: In the YGJY decoction treatment group, FN and TNF-α levels increased significantly (P < 0.01 and P < 0.05, respectively), and FNR and IL-1 levels decreased significantly (P < 0.05 and P < 0.05, respectively). In the control group, FN, FNR, TNF-α, and IL-1 levels did not significantly change. CONCLUSION: YGJY decoction could prevent hepatic fibrosis by adjusting the plasma levels of FN, FNR, TNF-α and IL-1, which could mediate cirrhosis formation. This data is of clinical significance.
