ABSTRACT

【Objective】 To retrospectively investigate the antibody distribution and pregnancy outcome of pregnant women with Rh alloantibody in Guangzhou, and summarize the prevalence, diagnosis and treatment experience of hemolytic disease of newborn (HDN) caused by Rh alloantibody, so as to provide data for the prevention, diagnosis and treatment of Rh-HDN. 【Methods】 A total of 17 345 pregnant women in Guangzhou from January 2014 to December 2020 were selected for irregular antibody screening test.Those with Rh antibody were followed up for delivery, and the clinical and laboratory examination results of pregnant women and newborns were analyzed. 【Results】 A total of 71 cases (0.41%, 17/17 345) with Rh alloantibodies were detected.Among them, anti-D, anti-E, anti-Ec, anti-C, anti-Ce, anti-c, anti-e accounted for 26.76% (19/71), 46.48% (33/71), 9.86% (7/71), 7.04% (5/71), 5.63% (4/71), 2.82% (2/71) and 1.41% (1/71), respectively.Among the 71 pregnant women, 34 gave birth to children with HDN, with the total prevalence rate of 47.89%, among whom 100%, 78.94% and 42.42% were anti-c, anti-D and anti-E, respectively.And 71.43% (5/7) of the children who underwent transfusion were with anti-D.Although the yield rate of anti-E was the highest, it involved low morbidity and mild symptoms, which preferred to occur in the first fetus.No significant difference in gestational age, birth weight and the occurrence time of jaundice was notice between the anti-D group and anti-E group, but the total bilirubin of the anti-E group was lower while the Hb level were higher than those of the anti-D group (P<0.05). Two children died, and others were cured by phototherapy, albumin, IVIG and blood transfusion. 【Conclusion】 The publicity of Rh-HDN for early prevention and treatment should be strengthened to improve the cure rate and the prognosis.

ABSTRACT

Purpose To explore the expression and clinical significance of CD47 in triple negative breast carcinoma (TNBC),and to analyze the relationship between CD47 expression and clinicopathologic features.Methods Immunohistochemical of Bond Polymer Refine Detection staining was performed on tissue array.It contains 185 cases of TNBC and 35 cases of non triple negative breast carcinoma (NTNBC).Then we observed the expression of CD47 in TNBC,and analyzed the relationship between the expression of CD47 and various clinical pathological characteristics.Results The expression of CD47 in tumor cells of TNBC was higher than that in NTNBC,and the difference was statistically significant (P < 0.05).The CD47 expression rate in TNBC tumors was 52.3%.It was closely related to clinical stage (P < 0.05),lymph node metastasis and distant metastasis (P < 0.05) and vascular invasion (P < 0.05).Conclusion The expression of CD47 is correlated with the clinical stage,lymph node metastasis,distant metastasis and vascular invasion of TNBC.CD47 can be used as a prognostic indicator and a potential target for immune therapy.

ABSTRACT

Objective To build the indicators system for clinical pathway management as required by clinical pathway control.Methods An indicators system was proposed by means of evidence-based review,focus group discussions,and ratings of the indicators' importance by doctors and nurses.A multidisciplinary panel of 60 experts from across the country were selected.A 3-round Delphi survey was made on the proposed indicators.The weights of the indicators were established by analytical hierarchy process (AHP).The response rate,Cronbach's α,and the authority coefficient of experts were used as a measure of reliability.Results The response rates of the 3 rounds were 85%,70%,and 94%; the experts authority coefficient was 0.80.The ccoefficient of variation falls with the rising number of consultations.The Kendall's W ranged from 0.40 to 0.83.Following the 3 rounds,consensus was achieved among experts as such a system comprising three first-level,9 second-level,and 36 third-level indicators.Conclusion The expert consultation has achieved reliable results.The established indicators system can serve as a useful instrument for standardized development of clinical pathways management and constant improvement.
