Various tumor marker-guided treatment regimens can considerably improve patient prognosis with a better understanding of the molecular underpinnings of ovarian cancer recurrence and metastasis. Fluorine-18-fluorodeoxyglucose Positron emission tomography/computed tomography (18F-FDG PET/CT) is a molecular imaging tool that provides anatomical and functional information about the tumor, and its volume-based metabolic parameters allow for quantifiable observation of ovarian cancer recurrence, prognosis, and therapeutic efficacy. The combined utilization of serological and radiologic markers has been found to provide increased clinical benefit. This article reviewed the predictive value of serum tumor markers and 18F-FDG PET/CT volumetric metabolic parameters for the prognosis of patients with ovarian cancer.展开更多

Methods:We evaluated 46 women with MFO and 30 normal women as controls. All the subjects were given 75g of glucose orally in order to perform the oral glucose tolerance test (OGTT) and insulin releasing test (IRT), and they were also evaluated for insulin resistance using the insulin resistance index with homeostatic model assessment (HOMA). Results:The occurrence of impaired glucose tolerance in women with MOF was 10.87%, which was significantly higher than that in the control group (3.33% ,P 〈 0.05). The rate of insulin resistance was 30.43% in the study group as compared to 10.00% in the control group. The results showed that there was significant difference between the two groups(P 〈 0.05). The levels of FSH,LH,PRL,E2,T and P between the two groups had no significant difference (P 〉 0.05). BMI in women with impaired glucose tolerance was correlated positively to insulin resistance (r = 0.567, P 〈 0.05). Conclusion:Abnormal glucose metabolism was observed in women with unitary multiple ovarian follicles, and this could be attributed to obesity and insulin resistance. Women with MOF and associated obesity should be subjected to OGTT so that their glucose levels can be monitored as a preventive measure.展开更多

A total sixty normal calving pluriparous buffaloes were examined between 14th and 75th day post partum (p.p.) rectaly, ultrasonically and blood sampling were collected on weekly sessions. There were differences (P < 0.01) between pregnant (PREG) and non-pregnant (NPREG) groups in Body condition score (BCS) and body weights. There was a difference between previous gravid uterine horn (PGUH) and non-gravid uterine horn (NPGUH) diameter in PREG and NPREG groups at 28th day p.p. The calving to first service interval in the PREG group was shorter (P = 0.03) than that of NPREG one. The number of buffaloes with dominant follicles (DF 3 8 mmdiameter) in ipsilateral and contralateral ovary to the PGUH in PREG group was higher (P < 0.01) than in NPREG. The calving to first service interval in the PREG group having DF in the ovary ipsilateral to the PGUH (n = 16) was shorter (P < 0.01) than those buffaloes having no DF (n = 18). The number of service per conception and days open in the PREG buffaloes which had no DF in the ovary ipsilateral to the PGUH were higher and longer (P < 0.01) than that which had DF group. The values of glucose and triglyceride were higher (P = 0.057) in PREG than NPREG group. In conclusion, postpartum ovarian activity has positive effect on the uterine involution and postpartum profile of some metabolities may be a good predictor of fertility status of buffaloes.展开更多

Serum was collected 14 d after model making to determine the contents of sex hormones and bone metabolism markers, ovarian tissue was collected to determine the expression of apoptosis genes and tibial tissue was collected to determine the expression of bone metabolism marker genes.Results: FSH, LH,β-CTX and TRACP5b levels in serum of model group were significantly higher than those of control group whereas E2, PINP and N-MID levels were significantly lower than those of control group;Fas, FasL, APAF-1 and Caspase-3 mRNA expression in ovarian tissue of model group were significantly higher than those of control group whereas Bcl-2 and XIAP mRNA expression were significantly lower than those of control group;RUNX2, BAP and OPG mRNA expression in bone tissue of model group were significantly lower than those of control group whereas RANKL and RANK mRNA expression were significantly higher than those of control group.Conclusion:There are sex hormone changes, apoptosis aggravation in ovarian tissue and systemic bone metabolism disorder in rat model with tripterygium wilfordii-induced premature ovarian failure.展开更多
