Objective To summarize and analyze prenatal ultrasound and postnatal autopsy ifndings in fetuses with urorectal septum malformation sequence (URSMS). Methods An analysis of prenatal ultrsound ifndings and postnatal autopsy features was performed on eleven cases of fetuses with URSMS that were identiifed by ultrasonography at Shenzhen Maternity&Child Healthcare Hospital in the period of January 2003 to December 2012. Results Prenatal ultrasonography showed a large abdominal cystic mass concomitant with imperforate anus in eleven fetuses with URSMS. The cyst contained unilocular or bilocular cystic structures in two fetuses, and trilocular cystic structures in nine fetuses. The cyst was demonstrated as clear acoustic transmission in three fetuses and unclear in eight fetuses. Out of them, seven fetuses had kidney abnormalities, six had ascites, and three had enterolithiasis. The associated systemic abnormalities included tethered cord in two fetuses, single umbilical artery in two fetuses, sacrococcygeal dysplasia in one fetus, and myocardial noncompaction in one fetus. 21-trisomy was found in one fetus by chromosome examination. Eleven cases were all identiifed as female fetuses by autopsy ifndings, including a single perineal opening and ambiguous genitalia with clitoral hypertrophy and labial fusion. The internal genital abnormalities included double vagina or longitudinal vaginal septum in nine fetuses, double uterus or uterus bicornis in ten fetuses and vaginal dysplasia in one fetus. Conclusions URSMS is a complex congenital malformation, which includes abnormalities of the urinary system, reproductive system and gastrointestinal track. An abdominal cystic mass visualized by prenatal ultrasonography might be the distinctive lesion in female with URSMS, and have an important diagnostic value. The kidney abnormalities and ambiguous genitalia can contribute to the diagnosis of URSMS.

ObjectiveTo summarize prenatal ultrasound image features of Cantrell′s syndrome (Cantrell′s pentalogy).MethodsFrom January 2007 to December 2013 in Shenzhen Maternity & Child Healthcare Hospital, there were twenty cases diagnosed and conifrmed by postmortem as Cantrell′s syndrome. The prenatal ultrasound image features and outcomes were analyzed.ResultsAmong the twenty cases, eighteen were singleton and two were twins with the other normal fetus. Prenatal ultrasound image: two obvious ultrasound image features of ectopic heart and hight omphalocele (seventeen cases) or gastroschisis (three cases) were appeared in prenatal ultrasound of twenty cases. Fourteen cases were complete ectopic heart (Ectopic heart was located within the omphalocele in one case, ectopic heart was completely exposed in amniotic lfuid in thirteen cases), six cases were incomplete ectopic heart, three cases were ventricular septal defect in which one was associated with pulmonary stenosis, two cases were single atrium and single ventricle in which one was associated with a single arterial trunk, one case was tetralogy of Fallot, and six cases were without signiifcant heart abnormalities. Associated with other abnormalities: seventeen cases were associated with other abnormalities in twenty cases, in which eleven cases were spinal abnormalities, nine cases were umbilical cord abnormalities (short umbilical cord in six cases, single umbilical artery in two cases, short umbilical cord associated with single umbilical artery in one case), ifve cases were neurological abnormalities (exencephalia in four cases, encephalocele in one case), four cases were limb abnormalities, three cases were cheilopalatognathus, one case was giant bladder. Three cases weren′t associated with other abnormalities. Nuchal Translucency: in eight cases, nuchal translucency were measured in early pregnancy. Nuchal translucency of ifve cases were thick, one case was cervical hygroma in one of the two twins. Chromosome examination results: only three cases had chromosome examination in twenty cases, in which one case was trisomy 21, another two were chromosome normal. Fetal outcome and examination results: in twenty cases, one of the two twins can′t survive after birth, and the other one of two twins was reduced in intrauterine, so the specimen could not be obtained. Eighteen cases of singleton underwent labor induction. The results of postmortem appearance (nineteen cases) and autopsies (ifve cases) were all consistent with prenatal ultrasound scan.ConclusionsEctopic heart and hight omphalocele or gastroschisis appearing at the same time was the characteristic of Cantrell′s syndrome in prenatal ultrasound and other abnormalities may be part of the Cantrell′s syndrome spectrum. It is beneift to detect and diagnose Cantrell′s syndrome by prenatal ultrasound in the ifrst trimester.

Objective To investigate the clinical value of acoustic radiation forcs impulse (ARFI)in quantitative evaluating placental elasticity.Methods The study population included 487 normal pregnant women,and ARFI generated shear wave velocity (SWV)was measured.On the basis of gestational ages, placental sites and sampling depths in region of interest (ROI),the normal population was divided into different groups.One-way analysis of variance was used to compare the discrepancy on the SWV values amomg the nomal placental sites or the sampling depths in ROI.Pearson correlation coefficient were used to assess the possible relationships between the normal placental SWV values and the different gestational ages or the placental grades.A total of 5 1 cases were diagnosed with severe preeclampsia,among them 25 cases were categorized as severe preeclampsia with fetal growth restriction (FGR).The placental SWV values were measured and compared with those of the normal population.The pathological examinations were performed on 50 normal and 5 1 abnormal placentas.Results Basing on the placental sites,the normal population were divided into three groups:anterior wall,lateral wall and posterior wall groups.Compared with the posterior wall group,the placental SWV values in the anterior wall or lateral wall group significantly decreased (P <0.05).No statistical significant difference was found between the anterior wall group and the lateral wall group.Basing on the distance from the sampling depths to the probe (range from 2 to 7.99 cm,and each additional 1 cm corresponding a group),the normal population were divided into six groups.There was statistical significant difference for the placental SWV values between the two groups of distance in the range of 2.0 to 5.99 cm and 6.0 to 7.99 cm (P <0.05).There was no statistical significant difference between the other two groups.The mean SWV value was (0.78±0.08 m/s)in the normal group. No significant relationships were found between the placental SWV values and the gestational ages of the normal population.However the placental SWV values were significantly related to the placental grades.For the placental SWV values,there was statistical significant difference between the normal group and the abnormal group (P <0.05).No statistical significant difference was found between the severe preeclampsia group and the severe preeclampsia with FGR group.The pathological examinations also showed significant changes in the abnormal group.Conclusions ARFI may quantitatively analyze the placental elasticity and make a difference between nomal and abnormal placenta.

OBJECTIVETo investigate the clinical features of Epstein-Barr virus-related hemophagocytic lymphohistiocytosis (EBV-HLH), to analysis the outcome of HLH-2004 protocol, and to explore the prognostic factors in EBV-HLH patients.

METHODSThe clinical features at onset and outcome of HLH-2004 protocol from 83 pediatric patients with EBV-HLH enrolled from January 2006 to December 2009 in our hospital were analyzed retrospectively. Univariate and multivariate COX regression analysis were used to identify statistically significant prognostic factors.

RESULTS(1) Among the 83 patients, 45 were males and 38 were females. The age of onset ranged from 6 months to 14 years 4 months. 44 patients were treated with HLH-2004, and 3-year overall survival (OS) was (55.8 ± 7.9)%. (2) The most common clinical features of EBV-HLH included high fever, cytopenia, hepatosplenomegaly, and coagulopathy; The respiratory symptoms, angina phlogistic, skin rashes, neurologic abnormality were rare. 97.3% of patients showed an elevation of serum ferritin, liver dysfunction and lipid metabolism disorders was found in most of EBV-HLH patients. 89.0% of patient had hemophagocytosis in bone marrow at diagnosis of EBV-HLH. (3) COX regression analysis revealed that anemia degree, serum albumin < 30 g/L, CD4:CD8 abnormity, NK cell < 3%, treatment protocol were related with the prognosis significantly (P < 0.05).

CONCLUSIONEBV-HLH in pediatric patients has severe clinical feature and poor prognosis. HLH-2004 protocol is an effective treatment for patients with EBV-HLH. Symptomatic treatment can't rescue the patients of EBV-HLH.

Objective To explore the correlation of liver depression grading with estrogen receptor alpha and beta(ERα,ERβ)and G protein-couple receptor 30(GPR30)of the perimenopausal women suffering from non-organic insomnia. Methods A total of 127 perimenopausal women suffering from non-organic insomnia were enrolled into the study. The data collected by four diagnostic methods and the scores of Pittsburgh Sleep Quality Index(PSQI)were used for the scoring and grading of liver depression according to Syndrome Element Differentiation. The mRNA and protein expression levels of ERα,ERβand GPR30 in the mononuclear cells of peripheral blood from the patients were detected with real-time fluorescence quantitative polymerase chain reaction (RT-qPCR) and Western blot (WB)method respectively. Results (1)The differences of mRNA levels of ERα,ERβ and GPR30 were insignificant among the patients with different degrees of liver depression (P > 0.05). ERα mRNA/ERβ mRNA ratio was decreased with the increase of liver depression grading,the differences being significant (F = 6.710, P < 0.001). (2) The differences of protein levels of ERα, ERβ and GPR30 were insignificant among the patients with different degrees of liver depression (P > 0.05);ERα/ERβ protein gray value ratio was decreased with the increase of liver depression grading, and the differences were significant (P < 0.05) . Conclusion The decline of ERα/ERβ is probably contributed to the pathological basis of liver depression in perimenopausal non-organic insomnia women.

OBJECTIVEPPAR-gamma is associated with the differentiation, apoptosis, proliferation and cytokine secretion of immunologic cells. This study investigated peripheral blood lymphoblastic PPAR-gamma mRNA expression and its correlation with plasma IL-13 contents in children with acute idiopathic thrombocytopenic purpura (ITP).

METHODSFifty-three children with acute ITP who were in line with the standard test between September 2007 and July 2008 were enrolled. Fifty healthy children during the same period were used as the control group. PPAR-gamma mRNA expression in peripheral blood lymphocytes were detected by RT-PCR. Plasma IL-13 contents were detected using ELISA.

RESULTSPPAR-gamma mRNA expression in peripheral blood lymphocytes from acute ITP children were significantly higher than that in the control group (0.78 +/- 0.03 vs 0.52 +/- 0.05; P< 0.05). Plasma IL-13 contents in children with acute ITP were also significantly higher than those in the control group (160.21 +/- 34.26 pg/mL vs 121.42 +/- 12.69 pg/mL; P< 0.05). There was a positive correlation between plasma IL-13 level and lymphoblastic PPAR-gamma mRNA expression in children with ITP (r=0.89, P< 0.05).

CONCLUSIONSPPAR-gamma mRNA expression in peripheral blood lymphocytes increased and were positively correlated with plasma IL-13 contents in children with acute ITP, suggesting that PPAR-gamma and IL-13 might participate in the pathogenesis of acute ITP.

Using the concepts and methods of epigenetics and metabolomics, to investigate the overall action molecular mechanism of Chrysanthemi indici C (CIC), the anti-hepatitis B virus (HBV) active extracts from Flos chrysanthemi indici. The inhibitory effects of CIC on proliferation and hepatitis B surface antigen (HBsAg), hepatitis B envelope antigen (HBeAg) and HBV-DNA of HepG2.2.15 cells were detected by CCK-8 and antigen kit. The DNA methyltransferases (DNMTs)/ten-eleven-translocation-2 (TET2) equilibrium was detected by ELISA. Illumina 850K methylation chip, pyrosequencing and qPCR were used to determine the action pathway and target of CIC by GO and KEGG analysis. Cell metabolites were extracted with 80% methanol, and the changes of differential metabolites, differential metabolic pathways and cell microenvironment were detected by LC-MS and other metabolomics methods. The results showed that CIC could inhibit the proliferation, HBsAg, HBeAg and HBV-DNA of HepG2.2.15 cells obviously, down-regulate DNA methyltransferase 1 (DNMT1), DNA methyltransferase 3a (DNMT3a) and DNA methyltransferase 3b (DNMT3b), up-regulate TET2, and restore the balance of DNMTs/TET2. The action targets of CIC were phospholipase C gamma 2 (PLCG2), phosphoinositide-3-kinase regulatory subunit 3 (PIK3R3), 1-acylglycerol-3-phosphate O-acyltransferase 2 (AGPAT2), 5-hydroxytryptamine receptor 2B (HTR2B), nerve growth factor (NGF), mainly involved in lipid metabolism, inflammation mediated regulation of transient receptor potential (TRP), phospholipase D signaling and advanced glycation end product-receptor for AGE (AGE-RAGE) signaling in diabetic complications pathways. CIC could significantly affect fatty acid metabolism and had great influence on phenolic acid, alkaloid and lipid metabolites in cell microenvironment. These results suggest that the action mechanism of CIC may be the synergistic action of multiple pathways and multiple targets, including related inflammatory pathways, immune pathways and lipid metabolism, through regulating epigenetic expression balance and restoring the balance of cell microenvironment.
