ABSTRACT
Objective:To explore the expression levels and the clinical significance of serum secreted frizzled-related protein 5 (SFRP5) and miR-124-3p in patients with hypertension during pregnancy.Methods:Ninety-eight patients with hypertension during pregnancy diagnosed from Jan. 2019 to Feb. 2022 were selected as the observation group. According to the degree of the condition of patients, they were divided into 41 cases of pregnancy hypertension, 32 cases of mild preeclampsia, and 25 cases of severe preeclampsia, and 80 healthy subjects during the same period were selected as the control group. Enzyme-linked immunosorbent assay (ELISA) was used to detect the expression level of serum SFRP5 in patients, real-time fluorescence quantitative method (qRT-PCR) was used to detect the expression level of miR-124-3p. The relationship between SFRP5, miR-124-3p levels and clinicopathological indicators in patients with hypertension in pregnancy was analyzed, Pearson correlation analysis was used to analyze the correlation between SFRP5 and miR-124-3p. Multivariate Logistic regression was used to analyze the risk factors of hypertension in pregnancy.Results:Compared with the control group, the serum SFRP5 expression level of the observation group [ (33.78±5.21) ng/L vs (43.34±8.56) ng/L] was down-regulated, while the miR-124-3p level [ (2.16±0.41) vs (1.01±0.17) ] was up-regulated, and the serum SFRP5 level of the observation group decreased with the severity of the disease[ (38.43±6.37) ng/L (33.18±5.14) ng/L (26.94±3.38) ng/L], while the level of miR-124-3p increased with the severity of the disease[ (1.62±0.24) (2.19±0.43) (3.01±0.69) ], the difference was statistically significant ( P<0.05) . The expression levels of SFRP5 and miR-124-3p in the serum of patients with hypertension in pregnancy were related to the age, pregnancy, pre-pregnancy BMI, and fasting blood glucose level of patients ( P<0.05) , but not related to the gestational age of patients ( P>0.05) . Bioinformatics TargetScan website showed that SFRP5 and miR-124-3p had binding sites. Pearson correlation analysis showed that SFRP5 and miR-124-3p were negatively correlated ( r=-0.610, P<0.05) . Multivariate Logistic regression analysis showed that SFRP5 was a protective factor for pregnancy-induced hypertension in pregnant women, and miR-124-3p was a risk factor ( P<0.05) . Conclusion:The serum levels of SFRP5 and miR-124-3p are abnormally expressed in patients with hypertension during pregnancy, and there is a certain relationship with the degree of disease. Both are involved in the occurrence and development of hypertension during pregnancy.
ABSTRACT
Objective To explore the occurrence of fetal chromosomal abnormalities among pregnant women with an adverse reproductive history using traditional karyotyping and single nucleotide polymorphism microarray(SNP-array)technology.Methods Totally 94 in 2 163(4.35%)cases of singleton pregnant women with an adverse reproductive history were performed amniocentesis in Jinhua Maternal and Child Health Care Hospital from June 2015 to June 2017. Traditional karyotyping and SNP-array were employed simultaneously for prenatal diagnosis,and the detection rates of the two methods were compared. Results All of the 94 specimens were successfully analyzed, 11 cases were found with chromosomal anomaly, the overall detection rate was 11.7%(11/94). Seven (7.4%,7/94) abnormalities cases were detected by karyotyping,and 7(7.4%)by SNP-array.The karyotyping results of trisomy 21,and 45,X and the deletion of chromosome 13 were consistent with SNP-array.Only 3(3.2%,3/94)microdeletion/duplications (the sizes of duplications and deletions were between 422.4-1 708.4 kb)and 1(1/4)loss of heterozygosity were detected by SNP-array,but were missed by karyotyping.Furthermore, 2 cases′copy number variation were found pathogenic gene related, while the other 2 were considered benign or variant of uncertain significance. Four cases(4/7)of abnormalities were detected by karyotyping, while confirmed balanced translocation and inversion by SNP-array.All patients were informed and chosen to continue the pregnancy.Conclusions The rate of abnormal fetal chromosomes in pregnant women with an adverse reproductive history is still high.SNP-array is a new molecular genetic technique,and combined with use of traditional karyotyping,it could improve the detection rate of fetal chromosomal abnormalities and reduce abortion rate, thus providing a basis for genetic counseling and prenatal diagnosis.
ABSTRACT
Objective To observe the effects of adiponectin on mRNA and protein expressions of connective tissue growth factor (CTGF) in hepatic stellate cells (HSCs) and the levels of procollagen type Ⅲ (PC Ⅲ) and hyaluronic acid (HA).Methods Cultured rat HSCs were treated with different concentrations of adiponectin.CTGF mRNA and protein expressions were analyzed by reverse transcription polymerase chain reaction (RT-PCR) and Western Blot.The levels of PCⅢ and HA were detected by enzymelinked immunosorbent assay (ELISA).Results Compared with the control group,the result of RT-PCR showed that the four groups had different degrees of inhibitory effect,of which group D exhibited the strongest inhibitory effect.The absorbance ratio was 1.54 ±0.18,1.21 ±0.14,0.96 ±0.10,and 0.79 ± 0.08,respectively (t =2.42,P ＜0.05;t =2.73,P ＜0.05;t =3.28,P ＜0.01;t =4.67,P ＜0.01).Western Blot also indicated that four groups had different degrees of inhibitory effect,of which D group exhibited the strongest inhibitory effect.The ratio of integral absorption was 1.54 ± 0.18,1.21 ±0.14,0.96±0.10,and 0.79 ±0.08,respectively (t =2.84,P ＜0.01;t =4.05,P ＜0.01;t =6.25,P ＜0.01;t =9.72,P ＜0.01).The levels of PCⅢ and HA secreted in culture media were also decreased.It was significantly decreased with the concentration of adiponectin increased.Conclusion Adiponectin can inhibit the levels of PC Ⅲ and HA,which may be achieved through reducing CTGF mRNA and protein expressions.
