Objective To improve the accuracy of diagnosis and differential diagnosis by summarizing imaging characteristics of spinal giant cell tumor of bone (GCTB).Methods Total 28 cases of spinal GCT were confirmed by pathology,of which 2 localized in cervical vertebra,8 in thoracic vertebra,8 in lumbar vertebra,and the other 10 lesions in the sacrum.All patients underwent X-ray,CT,and MRI scanning.Results (1)The incidence of spinal GCTB in the sacrum is highest,up to 35.7%.Lesions can locate in single or more vertebral bodies.All of the 10 cases with primary lesion locating the sacrum were involved in more vertebral bodies. (2)X-ray and CT showed central or eccentric vertebral destruction with 22 cases involving in adnexal bones,21 cases with bone crest or bony septum and 26 cases with soft tissue mass.(3)Lesions examined with MRI showed inhomogeneous isointense or slight hy-pointense on T1 WI,inhomogeneous hyperintense or isointense on T2 WI and inhomogeneous hyperintense or slight hyperintense on STIR.(4)Expansive bone destruction and soft tissue mass occurred again in postoperative recurrent lesions.Conclusion X-ray,CT and MRI are of significant value in the diagnosis of the spinal GCT.The combination of the three is helpful to improve the accuracy of diagnosis and differential diagnosis.

Objective To explore a proper dose of endothelial progenitor cells (EPCs)administration that can achieve optimal hematopoietic improving effectiveness in a murine allogeneic hernatopoietic stem cell transplantation (allo-HSCT) model.Methods Female Balb/c mice were lethally irradiated with 60Co source,and then were injected intravenously with 5 106 bone marrow cells from C57BL/6 mice (bone marrow transplantation group).In co-transfer experiments,5 × 104,1 ×105,5 × 105 or 1 × 106 donor EPCs (EPCs treated groups) were injected simultaneously with bone marrow cells.The recipients were monitored for survival,peripheral white blood cells,hematopoietic stem cells (HSCs) and bone marrow histology.Results Compared with bone marrow transplantation group,all EPCs treated groups had accelerated recovery of peripheral white blood cells (P＜0.05),platelets (P＜0.05) and HSCs (P＜0.05).When infused with less than 5 × 105 EPCs,these effective hernatopoietic improving phenomena showed a positive correlation with the administrated doses of EPCs.However,when infused with 1 × 106 EPCs,the mice showed lower survival rate (P＜0.05)and slower recovery of peripheral white blood cells (P＜0.05),platelets (P＜0.05) and HSCs (P＜0.05) than 5 × 105 EPCs treated grpup.Bone marrow histopathology analysis confirmed the above findings.Conclusion Co-transfer with donor EPCs can improve survival rate and hematopoietic reconstitution of recipient mice in allo-HSCT,and 5 × 105 EPCs should be a proper dose to achieve the best effectiveness.

OBJECTIVETo analyze the value of ovarian reserve markers for predicting ovarian response in women undergoing in vitro fertilization-embryo transfer.

METHODSAccording to the ovarian response, 331 patients undergoing oocyte retrieval cycles were divided into of normal, poor, and high response groups. Serum anti-Mvllerian hormone (AMH) was determined using AMH ELISA kit on day 3 of the menstrual cycle, antral follicle count (AFC) was measured using vaginal ultrasound, and basal serum follicle-stimulating hormone (FSH), luteinizing hormone (LH) and estradiol (E(2)) levels were detected using chemiluminescence method.

RESULTSSerum AMH and FSH levels, FSH/LH ratio, AFC, and the patients age, but not the basal E(2) level (P>0.05), were correlated with the number of oocytes collected (×1000/ampules of Gn) (P<0.001). AFC and serum AMH were the strongest single predictors for low ovarian response, with the areas under curve (AUC) of 0.855 (0.787-0.924) and 0.832 (0.764-0.900) (P<0.05), and cutoff values of ≤9 and ≤1.88 ng/ml, respectively. AFC was the strongest single predictor for high ovarian response, with an AUC of 0.787 (0.728-0.847) and the cutoff value of ≥15. Logistic regression model found that the combination of AFC, serum AMH and FSH improved the predictive power for poor ovarian response, but not for high ovarian response.

CONCLUSIONAFC, serum AMH, FSH, FSH/LH, and age are all predictors of ovarian response, among which AFC is the strongest single predictor. A multivariable model can improve the predictive power for low ovarian response but not for high ovarian response.

OBJECTIVETo investigate the effects of oral dydrogesterone for luteal phase support after frozen embryo transfer (FET) cycles on the clinical outcomes.

METHODSA total of 1643 FET cycles in our center between January, 2010 and September, 2011 were analyzed. The patients were divided into group A with natural-cycle FET and group B with hormone replacement cycle (HRT-FET). The two groups were further divided into two subgroups to receive oral dydrogesterone (groups AI and BI, n=358 and 185, respectively) or intramuscular progesterone with progynova (groups AII and BII, n=634 and 466, respectively) as luteal phase support. The clinical pregnancy rates, implantation rates, early miscarriage rates, ectopic pregnancy rates, ongoing pregnancy rates and delivery rates were compared between the subgroups.

RESULTSThere were no significant differences in the clinical outcomes between the patients receiving dydrogesterone and intramuscular progesterone as luteal phase support in either natural-cycle FET or HRT FET (P>0.05).

CONCLUSIONIn the FET cycles, oral dydrogesterone tablets for luteal support can achieve good clinical outcomes comparable with those by intramuscular progesterone and serves as a good alternative for luteal phase support.
