OBJECTIVETo investigate the autopsy characteristics, pathologic type, malfomation and genetic characteristics of complete atrioventricular septal defect (CAVSD).
METHODSThirty five cases of CAVSD were collected from Maternal and Child Hospital of Haidian District during Jan.2003 to Jan.2015. Autoptic material, clinical history and chromosome examination were reviewed.
RESULTSAmong 35 cases of CAVSD between 18-38 gestational weeks, there were 26 cases with CAVSD A (74.3%, 26/35), 1 case with CAVSD B (2.8%, 1/35) and 8 cases with CAVSD C (22.8%, 8/35). Only CAVSD malformation was seen in 4 cases (11.4%, 4/35). Multiple malformations were seen in 31 cases (88.6%, 31/35). Combined malformations most frequently occurred in cardiovascular, respiratory and locomotor system. Among 15 cases with chromosome examination, chromosome aberrations was found in 13 cases (13/15) and trisomy-21 was found in 11 cases (11/15).
CONCLUSIONSCAVSD is a rare disease and CAVSD A is the most common type. CAVSD is usually combined with other malformations and chromosome aberrations.

OBJECTIVETo study the expression and clinicopathologic significance of cancer stem cell markers CD44v6 and CD24 in ovarian serous carcinoma tissues.
METHODSOne hundred and two cases of ovarian carcinoma diagnosed during the period from June, 2001 to December, 2010 were retrieved from archival files. The histology slides were reviewed and a two-tier system for grading of ovarian serous carcinoma was applied. The expression of CD44v6 and CD24 was detected by immunohistochemistry using EnVision method. The relationship between CD44v6/CD24 expression and various clinicopathologic parameters was analyzed.
RESULTSThere were 46.1% (47/102) and 59.8% (61/102) cases expressing CD44v6 and CD24, respectively. Both CD44v6 and CD24 expression showed positive correlation with higher histopathologic grade (P = 0.003 and P < 0.05, respectively). CD24 expression also correlated with the presence of lymph node metastasis (P < 0.05). There was no statistically significant relationship between the expression of these two markers (χ(2) = 0.394, P = 0.530). The age of the patients, histopathologic grade, clinical stage and nodal status correlated with progression-free survival time (P < 0.05). CD44v6 expression and histopathologic grade correlated with the overall survival time (P < 0.05). Patient age was an independent poor prognostic factor by multivariate analysis.
CONCLUSIONSCD44v6 expression, age older than 50 years, high clinical stage and presence of lymph node metastasis are associated with poor prognosis in patients with ovarian serous carcinoma. The two-tier system for grading of ovarian serous carcinoma is useful in predicting survival; and high tumor grade represents an important poor prognostic indicator for ovarian serous carcinoma.

Objective:To investigate the clinicopathological and genetic features of confined placental mosaicism (CPM) and its effect on fetal intrauterine growth.Methods:Fourteen CPM cases of Haidian Maternal and Children Health Hospital were collected from May 2018 to March 2022. Clinicopathological examination on placental specimens and molecular genetic analysis were performed.Results:The age of the parturient women ranged from 27 to 34 years, with an average age of (30.0±3.54) years. The gestational weeks ranged from 35 +1 to 41 +2 weeks. There were 4 premature births and 10 term births, among which 6 were female and 8 were male fetuses. Nine cases (9/14) had adverse pregnancy outcomes, including 7 cases of fetal growth restriction. The weight of CPM placenta decreased, with 6 cases below the 10th percentile of weight standards and 5 cases between the 10th and 25th percentile. All 14 CPM placental specimens showed morphological changes of perfusion dysfunction to varying degrees, with mainly placental-maternal vascular malperfusion followed by placental-fetal vascular malperfusion. The mosaic chromosomes in different CPM cases varied, with 16-trisomy/monosomy mosaicism being the most common followed by 7-trisomy and 21-trisomy/monosomy mosaicism. The mosaic proportion was unequal in different parts of the same CPM placenta, with the mosaic proportion of umbilical cord, fetal membranes, fetal surface, maternal surface, and edge ranging from 1% to 70%. Conclusions:The mosaic chromosomes in different CPM cases vary, and the mosaic proportion is unequal in different parts of the same CPM placenta. The pathological morphology is mainly manifested as perfusion dysfunction, which can lead to adverse pregnancy outcomes such as fetal growth restriction and preterm birth.
