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 study curative efficacy of carboprost romethamine in treatment of postpartum hemorrhage of pregnancy and its effects on fibrinogen(FIB) and D-dimer(D-D).Methods106 patients of chronic renal failure who received therapy from November 2015 to November 2016 in our hospital were selected.According to random number table, those patients were divided into the observation group (n=53) and the control group (n=53).The control group was treated with oxytocin after delivery, while the observation group was treated with carboprost romethamine.The postoperative 2h and 24h bleeding volume, contraction duration, duration of lochia, uterus decreased speed and the changes of FIB and D-D before and after treatment were compared, and comparison of adverse reactions.ResultsThe postoperative 2h and 24h bleeding volume in the observation group were significantly lower than those in the control group[(231.58±36.79)mL vs (345.62±45.60)mL, (301.24±44.01)mL vs (445.23±61.74)mL] (P<0.05);compared with the control group, the observation group contraction duration longer, duration of lochia was shorter, uterus decreased was faster(P<0.05);before treatment, there was no significant difference in FIB and D-D between the two groups;after treatment, the levels of FIB and D-D in the control group did not change significantly;the levels of FIB and D-D in the observation group were significantly reduce, and the result were lower than those in the control group(P<0.05);there was no significant difference in the incidence of nausea and vomiting, chest pain, chills between the two groups.ConclusionCarboprost romethamine is well for postpartum hemorrhage of pregnancy, which can effectively improve blood hypercoagulable state, reduce the amount of postpartum hemorrhage, it's worthy of application and promotion.
ABSTRACT
Purpose: To evaluate the performances for detection of IgM and IgG antibodies to Orientia. tsutsugamushi (Ot) using a gold conjugate-based rapid diagnostic test (RDT). Materials and Methods: The RDT employing mixture recombinant 56-kDa proteins of O. tsutsugamushi and the mIFA assay was performed on 33 patients from Fujian and Yunnan province respectively and 94 positive sera (36 from Hainan province and 58 from Jiangsu province) from convalescent stages of the patients with scrub typhus respectively and 82 negative sera from healthy farmers from Anhui province and Beijing City respectively in 2009. A comparison of the RDT and mIFA assay was performed by using the c2 test and the P level of ≤0.05 was considered to be significant. Results: Among these 94 positive sera from convalescent stages of the illness and 82 sera from control farmers, the specificity of RDT was 100% for both IgM and IgG tests. In 33 cases with scrub typhus, 5 cases were positively detected earlier by RDT than by mIFA for the IgM test, and 2 cases were positive for the IgG test. The sensitivities of RDT were 93.9% and 90.9% for IgM and IgG, respectively. Considering IgM and IgG together, the sensitivity was 100%. The geometric mean titre (GMT) of IFA and the RDT assay in diluted sera from confirmed cases were 1:37 versus 1:113 respectively (P<0.001) for IgM test and 1:99 versus 1:279 respectively (P<0.016) for IgG. Conclusions: The RDT was more sensitive than the traditional IFA for the early diagnosis of scrub typhus and was particularly suitable for use in rural areas.
ABSTRACT
OBJECTIVE@#To evaluate the detection of IgM and IgG antibodies to Orientia tsutsugamushi (O. tsutsugamushi) by rapid diagnostic test (RDT) and microimmunofluorescence assay (mIFA).@*METHODS@#RDT using a mixture of recombinant 56-kDa proteins of O. tsutsugamushi and mIFA assay were performed on 20 patients from Fujian and 13 patients from Yunnan Province, and 82 sera samples from healthy farmers in Anhui Province and Beijing City in 2009. Comparison of the RDT and mIFA assay was performed by using X(2) test and the P level of <0.05 was considered to be significance.@*RESULTS@#Among these 82 normal sera samples, the specificity of RDT was 100% for both IgM and IgG tests. In 33 samples from patients with scrub typhus, 5 cases were positively detected earlier by RDT than by mIFA in IgM test, and 2 cases were positive in IgG test. Sensitivities of RDT were 93.9% and 90.9% for IgM and IgG, respectively. The sensitivity of combination test of IgM and IgG was 100%. Geometric mean titer diluted sera from confirmed cases by IFA and RDT assay were 1:37 vs. 1:113 (P<0.001) in IgM test and 1:99 vs. 1:279 (P<0.05) in IgG test.@*CONCLUSIONS@#RDT is more sensitivite than mIFA in the early diagnosis of scrub typhus and it is particularly applicable in rural areas.
