Objective To make a further understanding of mammographic features of simple cyst of the breast (SCB).Methods Molybdenum target radiographic signs in 39 cases with SCB proved pathologically and were retrospectively analyzed. Results Of the 56 SCB in 39 cases, 23 were diagnosed rightly as SCB, 10 as fibroadenoma, 2 as cancer and the remaining 4 were undefined. The diagnostic accuracy and misdiagnosis were 59.0% and 41.0% respectively. Radiograph showed round in 12, ovoid in 38, mild lobed in 4 and comet tail form in 2. The borders of cyst were distinct and sharp in 26, distinct partly and indistinct partly in 27,indistinct completely in 3. The density was homogeneous in 54 with calcifications in 2. Of the 56 SCB, the length axes of cyst were upright to chest wall in 20 and towards nipple in 18. The cysts could be transformed with pressure in 4.Conclusion Careful analysis of radiographic features of SCB is helpful for diagnosing accurately this disease.

Objective To investigate the clinical value of prenatal MRI in the diagnosis and differential diagnosis of congenital bronchopulmonary sequestration (BPS). Methods From January 2009 to December 2014, 16 fetuses with BPS were diagnosed by fetal MRI in Huzhou Maternity and Child Care Hospital and Shanghai Children′s Medical Center Affiliated to Shanghai Jiaotong University School of Medicine. The clinical data of these cases were analyzed retrospectively. All were singleton pregnancy, and MRI was carried out within 24-48 hours after routine prenatal ultrasound. All the neonates underwent postnatal enhanced CT scan or surgical biopsy after birth, and the results were compared to prenatal MRI diagnosis. Results (1)With prenatal MRI, 16 cases were diagnosed BPS. The lesions located in left lung in 10 cases, and right lung in 6 cases. As the scope of the lesion, 3 cases located in the whole left lung, 6 cases limited to the left lower lobe, and 1 case was subdiaphragmatic on the left side. 2 cases located in the whole right lung and 4 cases limited to the right lower lobe. One case complicated oligoamnios, and one had pleural effusion. Supplying vessels could be found in 14 cases.(2)When the postnatal results were compared with prenatal MRI, 15 cases were comfirmed as BPS (15/16), including 10 intralobar cases 5 extralobar cases. One that was diagnosed as BPS by prenatal MRI was confirmed to be congenital cystic adenomatoid malformation (CCAM) by pathology. The accuracy of prenatal MRI diagnosis of BPS was 15/16. Prenatal ultrasound missed one case and misdiagnosed two cases, as one was mistakened as CCAM and the other as cystic teratoma. Conclusion Prenatal MRI has good clinical value in the diagnosis and differential diagnosis of fetal BPS.

OBJECTIVETo analyze the Chinese medical syndrome typing laws in rheumatoid arthritis (RA) patients of the dampness-heat impeding syndrome and the cold-dampness impeding syndrome.

METHODSClinical data and serum of 322 inpatients and outpatients were collected to perform DAS28 score. Laboratory indices including erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), albumin (ALB), globulin (GLB), and blood routines (white blood cell, red blood cell, and platelet) were tested by conventional methods, and the serum levels of tumor necrosis factor (TNF)-alpha and interleukin (IL)-1beta were detected by ELISA. The difference of each index was analyzed between RA patients of the dampness-heat impeding syndrome and the cold-dampness impeding syndrome.

RESULTSThe levels of DAS28 scores, ESR, CRP, white blood cell count, and platelet of RA patients of the dampness-heat impeding syndrome were significantly higher than those of the cold-dampness impeding syndrome (P <0.01). The serum level of GLB of RA patients of the dampness-heat impeding syndrome was obviously higher than that of the cold-dampness impeding syndrome (P <0.01), while the serum ALB level of RA patients of the dampness-heat impeding syndrome was obviously lower than that of the cold-dampness impeding syndrome (P<0.01). Compared with the dampness-heat impeding syndrome, ROC curve results showed the area under the curve (AUC) were ranked from large to small as DAS28 score > ESR >CRP >GLB > PLT >WBC (P<0.01). Compared with the cold-dampness impeding syndrome, only ALB was of diagnostic value for cold-dampness impeding syndrome and the AUC was 0.636 (P = 0.000).

CONCLUSIONDAS28 score, ESR, CRP, PLT, WBC, GLB, and ALB could be used as objective index in identifying the differences between the dampness-heat impeding syndrome and the cold-dampness impeding syndrome in RA patients.

OBJECTIVETo study the extent of retinal vascular development and influencing factors at birth and the relation between retinal vascularization and retinopathy of prematurity (ROP).

METHODSFrom October, 2006 to December 2006, retinal vascularization was screened and evaluated in 84 neonates at different weeks of gestation and birth weights (BWs), had dilated fundus evaluation for zone of retinal vascularization by the 130 degrees lens of a digital fundus camera. The infants' pupils were dilated with 2.5% phenylephrine and 0.5% cyclopentolate eye drops. The study cohort was divided into subgroups depending on the weeks of gestation and birth weights. The control group consisted of healthy term infants. Maternal and neonatal factors were ascertained and analysed.

RESULTSVascularization up to zone I and II was considered to be immature retina; vascularization up to zone III or beyond was considered to be mature retina. In this study, 11 of 12 infants who were born at < 30 weeks of gestation, 12 of 26 infants who were born at < 31 approximately 33 weeks of gestation, 1 of 26 babies who were born at < 34 approximately 36 weeks of gestation and none of 20 babies who were born at < 37-40 weeks of gestation had immature retina; 12 of 15 babies at < 1500 g BW, 8 of 14 infants at 1500 g < BW < 1700 g, 4 of 11 infants at 1700 g < BW < 2000 g and of 44 infants at > 2000 g BW had immature retina. Those infants who were born at > 34 weeks of gestational age and at > 2000 g BW had mature retina. Infants who were born between 31 to 34 weeks of gestation and at 1501 to 2000 g BW had variable extent of retinal vascularization at birth. Vascularization was associated with postconceptional age (F = 31.9193, P = 0.000), birth weight (F = 32.4532, P = 0.000), anemia (F = 36.9391, P = 0.000), surfactant (F = 24.000, P = 0.0000), poor nutrition (F = 4.184, P = 0.041), RDS (F = 17.6191, P = 0.000), cesarean delivery (F = 10.972, P = 0.0022) and oxygen > 48 h (F = 22.076, P = 0.0000). Vascularization was affected mainly by the postconceptional age (95% CI = 1.57-261.728, P = 0.021). At last, 15/24 infants with immature retina developed ROP while none of the infants with mature retina developed ROP (chi2 = 45.1087, P = 0.000).

CONCLUSIONThere is considerable variability in the extent of retinal vascularization in infants who we born between 31 to 34 weeks of gestation. Modifiable maternal and fetal factors could influence extent of vascularization at birth. Immature retina is the critical factor of ROP. Gestational age is the main factor of the immature retina in premature infants.
