Objective To evaluate the value of early diagnosis and follow-up of bleeding and necrotizing pancreatitis by ultrasound.Methods 52 cases with bleeding and necrotizing pancreatitis confirmed by operation and pathology were examined by ultrasound. The pancreas were observed section by section in the blood vessel surrounding the pancreas acted as the mark under reduced the influence of gas in gastro-intestine and using adopting protruding probe with high resolution and compounding scanning technique in multi-posture. Results The accurate rate of diagnosis by ultrasound was 92%(48/52).During the follow-up period, pseudocysts and other complications were found in 9 cases, all cases recovered gradually after operations and treatment of symptoms except 3 cases who died caused by complications such as multiple organ dysfunction. Conclusion Ultrasound can identify bleeding and necrotizing pancreatitis early and also can regard as a significant follow-up method.

Objective To study the CT and MRI characteristics of myxoid soft tissue tumours.Methods Fifty-three myxoid soft tissue tumours pathologically confirmed were retrospectively studied.MR and CT scan were performed before operation.Noncontrast T1 and T2 weighted images,fat-suppressed T2 weighted images were obtained before contrast-enhanced scan with fat-suppressed T1 weighted sequence was underwent.Plain and contrast-enhanced CT was performed with tube potential of 120 kV,matrix 512 × 512,and automatic tube current modulation technique.Results There were 18 myxoid liposarcoma,3 ganglioneuroma,8 myxofibrosarcoma,2 extraskeletal myxoid chondrosarcoma,10 intramuscular myxoma,and 2 juxta-articular myxoma.Microscopic examination showed myxoid soft tissue tumours which were consisted of abundant myxoid stroma with tumour cells and blood vessels associated with fibrous bands.Low density in CT images,hypointensity in T1 weighted images,significantly hyperintense in T2 weighted images were their common manifestations in the area of abundance of extracellular myxiod matrix.Plain CT images demonstrated equidensite,T1 weighted images isointensity,and fat-suppressed T1 weighted images significant enhancement relatively in the areas of increased number of tumor cells.Hemorrhage,necrosis and capsule of the lesion were revealed in high grade malignant tumors.The septa can be identified in most of myxoid tumours of soft tissue.Conclusion CT and MRI can definitely show the image characteristics of myxiod soft tissue tumours,which can help make a qualitative diagnosis before operation.

To investigate the effect of dietary fiber on blood glucose and pregnancy outcomes in patients with gestational diabetes mellitus (GDM). One hundred and twelve patients with GDM in the second trimester of pregnancy were recruited from Women's Hospital, Zhejiang University School of Medicine. Patients were randomized into two groups with 56 in each group: the control group received basic nutrition support; while the dietary fiber group were given additional dietary fiber ( total dietary fiber per day) before meals in addition to basic nutrition support. Intervention for all cases lasted for 8 weeks. Fasting blood glucose and postprandial blood glucose (2 h BG) were measured every week, and oral glucose tolerance test (OGTT) was performed at 42 d postpartum to evaluate the glycemic outcomes. Perinatal outcomes were recorded. The dietary fiber intervention markedly improved 2 h BG in patients with GDM and significantly elevated the glucose compliance rate from the 3rd to 8th week compared to the control group ( <0.05 or <0.01). OGTT 2 h glucose and the incidence of impaired glucose tolerance in the dietary fiber group were significantly lower than those in the control group, while the glucose compliance rate was significantly higher than that in the control group (all <0.01). Moreover, the rates of adverse perinatal outcomes, such as premature rupture of membranes and neonatal hyperbilirubinemia were declined in the dietary fiber group (<0.05 or <0.01). Dietary fiber intervention can ameliorate hyperglycemia in GDM patients, improve perinatal outcomes and reduce the incidence of postpartum impaired glucose tolerance.
