Objective@#To evaluate the differential diagnosis of idiopathic granulomatous mastitis (IGM) and invasive ductal carcinoma.@*Methods@#The ultrasonographic data of 37 IGM patients and 50 cases of IDC were analyzed retrospectively. The shape, growth direction, margin, internal echo, posterior echo, calcification, Adler blood flow classification, PSV(peak sestolic velocity), RI (resistance index)and elasticity scores were analyzed by χ2 test and independent sample t test. The optimal cutoff values of age, PSV and RI were calculated by receiver operating characteristic (ROC) curve. Logistic regression analysis was used to calculate the odds ratio (OR) of ultrasonic variates in the diagnosis of both diseases.@*Results@#There were no significant differences in the shape, margin, internal echo and blood flow grading between the two groups. The age, lesion growth direction, posterior echo, calcification, PSV, RI and elasticity were statistically different. The cut-of value of Age, PSV and RI were 38.5 years old, 13.20 cm/s, and 0.655. Logistic regression multi-variated analysis revealed that elastic score (OR=9.806) had the best value of the differential diagnosis, as well as calcification (OR=6.937), posterior echo decay (OR=4.613), RI (OR=3.257), lesion growth orientation (OR=3.198), and PSV (OR=1.202). Lesion shape, margin, internal echo, and Adler blood flow classification did not help in differential diagnosis.@*Conclusion@#Ultrasound multi-parameter analysis has high value in IGM and IDC differential diagnosis.

Objective To study the effect of maternal hypertensive disorders complicating pregnancy on brain development of the neonates. Methods Insular area,circle and cerebral gyri width of lobus frontals were measured in 56 neonates of the mothers with hypertensive disorder complicating pregnancy(HDCP)by ultrasound and were compared with those of 53 neonates of the mothers without HDCP(control group). Results In the control group,the cerebral gyri width of term neonates was narrower than that of preterm neonates,while the insular circle was longer and the insular area was larger in the term neonates(P<0.01).Insular circle was significantly shorter and the insular area was significantly smaller in neonates of HDCP mothers [term:(87.43±10.21)mm,(413.60±90.05)mm2;preterm:(72.59±7.50)mm,(285.71±48.62)mm2]than those of the corresponding neonates in the control group[term:(102.14±9.97)mm,(557.08±98.89)mm2:preterm:(78.42±10.14)mm,(356.01±93.07)mm2].Cerebral gyri width were significantly wider only in the full term neonates.The incidence of small gestational age neonates was 30.36%(17/56)in hypertensive disorder complicating pregnancy group.The neonatal behavioral neurological score of hypertensive disorder complicating pregnancy group was significantly lower than that of control group (P<0.01). ConclusionsMaternal hypertensive disorder complicating pregnancy may result in poor development of brain of their neonates,which could be evaluated by cerebral ultrasound.

Objective To investigate the clinical value of double contrast-enhanced ultrasonography (DCUS)in diagnosing Lauren classification of advanced gastric carcinoma.Methods Fifty-eight patients with gastric cancer proved by endoscopic biopsy underwent preoperative DCUS examination,and the findings were compared with postoperative pathologic results via hematoxylin-eosin and alcian blue-periodic acid schiff(AB-PAS)staining.Results In 58 patients,34 cases were diagnosed as intestinal type and 24 cases as diffuse type by pathology after operation.In intestinal type,30 cases were enhanced as global homogeneous intensity by using DCUS.another 2 cases as"lamellar"model and the other 2 cases as heterogeneous intensity.However,in diffuse type,22 cases were enhanced heterogeneously with"barrier"signs in 5 cases,"map"signs in 9 cases and"lamellar"signs in 8 cases.the remaining 2 cases of diffuse type enhanced as homogeneous model.The sensitivity and specificity of heterogeneous enhancement in diagnosing diffuse type of advanced gastric cancer was 91.7%and 88.2%respectively,and the Youden's index was 0.8.Conclusions DCUS could be considered as a new valuable method to distinguish the Lauren classification and evaluate the invasiveness,metastasis and prognosis in patients with gastric carcinoma.

Objective To evaluate the value of Doppler indices of intrarenal artery (IRA) in clinicobservation in pregnancy induced hypertension(PIH).MethodsForty-six cases of PIH underwent Doppler measurment of PI,RI in IRA,and 186 normotensive pregnant women were measured as control.Results ①There was a larger increase of IRAPI and IRARI in PIH than in normal prgnant(P<0.001),and IRAPI is significantly higher in moderate and severe PIHs than in mild PIH(P<0.001),②IRAPI,IRARI correlate positively with classification of PIH(P<0.001),proteinuria(P<0.001)and MAP(P<0.05),and IRAPI is the best one.Conclusions It is of a certain significance to the clinical observation and treatment of PIH by using color Doppler to examine the indices of IRA in the pregnant women with PIH.
