Objective To summarize the MRI findings of spinal paraganglioma,in order to improve the diagnostic accuracy of imaging. Methods The MRI findings of 6 patients with spinal paraganglioma were retrospectively reviewed.All cases were proved by pathology.Results All 6 cases of spinal paraganglioma were located in lumbar spinal canal.There were serpentine vessels shade observed above the tumor in 5 cases.Two cases with smaller size of lesions exhibited as homogeneous signal intensity with homogenous enhancement. The other 4 cases with larger size of tumors exhibited as heterogeneous signal intensity because of intratumoral cystic change,hem-orrhage and hemosiderin deposit at the margin of the tumor.Conclusion Serpentine vessels above the tumor can be seen in spinal paragangliomas.Intratumoral cystic change and hemorrhage,hemosiderin deposit at the margin of the tumor are the MRI character-istics of spinal paraganglioma.

Objective To discuss the clinical effect of weight loss training and oral intake of mefformin on obese women with polycystic ovary syndrome.Methods 60 cases of obese women with polycystic ovary syndrome in Nan'an District Maternal and Child Health Hospital were studied.They were divided into 2 groups,30 cases in each group.The control group received simple weight loss training and the observation group received weight loss training combined with the oral administration of metformin.The clinical data of the 60 cases were retrospectively analyzed and the clinical efficacy and safety of different treatment methods were evaluated.Results After treatment,two groups of patients have been effectively improved.16 cases(53.3％)in the control group and 29 cases(96.7％)in the observation group resumed normal menstruation,and the differences had statistical significance.Fasting blood sugar(FBS),BMI,testosterone and luteinizing hormone levels of the two groups had significant improvement after treatment,in addition,the improvement of these indicator were more obvious in the observation group than those in the control group,and the difference had statistical significance.The difference of FBS,BMI,testosterone and luteinizing hormone levels had statistical significance between before and after treatment(P =0.003 7,0.001 2,0.002 0 and 0.002 4,respectively).Conclusion The combination therapy of weight loss training and oral intake of metformin is effective in treating obese women with polycystic ovary syndrome.It is the main method in treating obese women with polycystic ovary syndrome.

AIM:To explore the histopathological classification and incidence of orbital space-occupying lesions in children in order to provide references for the diagnosis of orbital space-occupying lesions in children.
METHODS:A total of 290 paediatric patients with orbital space - occupying lesions diagnosed by pathological examinations at the Second Hospital of Tianjin Medical University from January 1998 to December 2012 were retrospectively reviewed.
RESULTS:In 290 paediatric patients with orbital space-occupying lesions, venous hemangioma was the most common (58 cases,20. 0%), the other commons were as follows: hemangio lymphangioma, dermid cyst, neurofibroma, optic nerve glioma, rhabdomyo sarcoma and so on. Capillary hemangioma, venous hemangioma, optic nerve glioma had the predominant age incidence. On the other hand, optic nerve glioma, venous hemangioma, rhabdomyosarcoma had the predominant sex incidence.
CONCLUSION: The majority of paediatric patients with orbital space - occupying lesions are congenital and embryonic lesions, the most common of which is venous hemangioma. Some lesions had the predominant age and sex incidence.

Objective To investigate the analgesic effect of epidural labor analgesia with contin-uous background infusion and its impact on obstetric outcome.Methods This was a retrospective co-hort study.In the two months of march 2014 and march 201 5,503 nulliparas women who had re-ceived epidural analgesia for labor were enrolled and assigned to two different study groups according to their analgesic protocol.Two hundred and fifty-eight nulliparas in group C received only patient-controlled analgesia while two hundred and forty-five nulliparas in group P received patient-controlled analgesia with continuous background infusion.The basic and perinatal data of all enrolled nulliparas women were collected and analyzed to compare the analgesic effect and the impact on obstetric risk of two different analgesic protocol.Results The NRS pain score during the second labor stage was lower in group P [3 (3-4)scores vs.5 (4-5)scores](P <0.001).The second stage prolonged [50 (29-82) min vs.38 (24-62)min](P =0.001)and intrapartum hemorrhage increased [200 (100-250)ml vs. 1 50 (100-200)ml](P =0.003)in group P.There were no significant differences between the two groups with regard to the delivery mode (P =0.656)and the morbidity of postpartum hemorrhage (9.8% vs.10.9%,P =0.697).Analgesic protocol with background infusion was not associated with postpartum hemorrhage,instrumental delivery risk and cesarean risk.Conclusion Epidural labor an-algesia with continuous background infusion provided more effective analgesia in nulliparas,without additional obstetric risk.

AIM To investgate the changes in the expression of CREB and p-CREB in the cortex of ethanol dependent rats. On other hand, the effects of fluoxetine on these changes were also studied. METHODS Ethanol was administered in drinking water at the concentration of 6% V/V, for 28 d. The expression of CREB and p-CREB in the rat cortex were measured by immunohistochemistry methods. RESULTS It was found that chronic ethanol treatment and its withdrawal did not modify the expression of CREB in the rat cortex. However, the levels of p-CREB in the frontal and piriform cortex of rats were significantly decreased during ethanol withdrawal, and respectively decreased 57.28%?55.84% compared to control rats at 24 h after ethanol withdrawal. When fluoxetine (ip, 10 mg?kg -1) were administried concurrently with ethanol, it can significantly dampen alcohol withdrawal symptoms and antagonize the down-regulation of the phosphorylation of CREB in the frontal and piriform cortex of rats at 24 h after ethanol withdrawal, the expression of p-CREB protein respectively increased 292 58%,128 44% compared with rats intaking ethanol. CONCLUSION CREB may be one of the substance of the signal transduction process for ethanol dependence. Fluoxetine can reverse the decreased p-CREB levels in rat cortex induced by ethanol withdrawal, which may be the part reason of fluoxetine dampening alcohol withdrawal symptoms.
