Objective To construct a whole process nursing plan for women with vaginal delivery and to evaluate its effect.Methods On the basis of literature analysis and Delphi expert consultation method,a whole process nursing plan of vaginal delivery was established.From June to September 2023,180 primiparas in a tertiary A hospital in Ningxia were selected as research subjects to carry out the preliminary application of the plan.Among them,the parturients hospitalized from August to September were in the experimental group,and those hospitalized from June to July were in the control group.The experimental group received the whole process nursing plan on the basis of routine nursing,and the control group received routine nursing.The indexes related to delivery outcomes(delivery mode,time of each labor stage,et al),the degree of labor pain,fear of labor and labor experience were compared between the 2 groups.Results The effective recovery rates of the 2 rounds of expert correspondence were 100％and 93.75％,respectively,and the coefficient of expert authority was 0.85.The finally constructed plan included 3 first-level items,10 second-level items and 29 third-level items.86 cases and 85 cases were included in the experimental group and the control group,respectively.After intervention,there were statistically significant differences in each stage of labor between the 2 groups(P＜0.05).There was significant difference in the rate of good and good control of labor pain(x2=16.386,P＜0.001).The childbirth fear questionnaire score(27.76±3.60)of the experimental group was lower than(33.06±3.36)of the control group,and the childbirth experience score(80.83±4.83)was higher than(75.79±3.46)of the control group,and the differences were statistically significant(P＜0.001).Conclusion The whole process nursing plan of vaginal delivery is scientific and feasible.It can shorten the labor time,relieve labor pain,labor fear and improve labor experience.

Copy number variation encompassing SNP plays an important role in IVD and precision medi-cine.As the most commonly used method,FISH could not overcome the probe cross-reactivity which is common when to detect SNP.Here we developed a quantitative and qualitative method on copy number variation encompassing SNP.In this study,the rs76711854 was used as an example to establish a quanti-tative method by advantage of probe cross-reactivity.The fragment encompassing rs76711854 and its downstream to 9 514 bp were amplified by PCR.The allelic genotypes were verified by Sanger sequen-cing.Different probes with or without cross-reactivity to be used via quantitative real-time PCR and digit-al PCR.The different clusters(2D)and fluorescence intensity layers(1D)exist by adding probe with cross-reactivity.The A/G ratio measured by digital PCR is 2︰1,which is verified by probe targeting to the SNP.The copy-number variant exists in the 9kb-long fragment upstream to the SNP of prostate cancer cell line but not in human endometrial adenocarcinoma cell line Ishikawa.The data suggest that there is a multi-copy variation at this locus in DU145 cells.The method applied here is based on one single cross-reactivity probe via digital PCR.

Objective To explore the efficacy of magnetic resonance angiography(MRA)combined with CXC motif chemokine ligand 12(CXCL12)in predicting ischemic stroke in patients with transient ischemic attack(TIA).Methods A total of 225 patients with TIA were selected,and all patients underwent MRA and CXCL12 examination before treatment.The occurrence of ischemic stroke in TIA patients was counted within 1 week of treatment,the factors influencing the occurrence of ischemic stroke in TIA patients were analyzed,and the value of MRA combined with CXCL12 in predicting the occurrence of ischemic stroke in TIA patients was ana-lyzed.Results Among the 225 patients,21 of them had ischemic stroke.Multivariate logistic regression analysis showed that Essen stroke risk scale(ESRS)score,lesion site stenosis,and CXCL12 level were the factors influencing the occurrence of ischemic stroke in TIA patients(P<0.05).The receiver operating characteristic(ROC)curve showed that the sensitivity of lesion site stenosis,CXCL12 and their combination in predicting the occurrence of ischemic stroke in TIA patients was 76.19%,71.43%,and 85.71%,respectively,the specificity was 80.39%,70.10%,and 88.73%,respectively,and the area under the curve(AUC)was 0.798,0.733,and 0.895,respectively.Conclusion MRA combined with CXCL12 has good efficacy in predicting the occurrence of ischemic stroke in TIA patients.

P53 is a key tumor suppressor gene,which is regulated in many ways.Zinc finger 148(ZNF148)and SP5,as zinc finger transcription factors(TFs),play important roles in tumor suppression and carcinogenesis.The regulatory relationship between these two TFs and p53 has not been reported.In this paper,Ishikawa and A549 cell lines with different p53 expression levels were used as research mod-els to explore the transcriptional regulation of the P53 gene by ZNF148 and SP5.The data showed that there were differences in the expression of ZNF148 and SP5 in the two cell lines.The mRNA expression of ZNF148 in Ishikawa was 1.9 times higher than that of A549,and the mRNA expression of SP5 in A549 was 802.4 times that of ZNF148.Data showed that in Ishikawa cells,the expression of P53 de-creased(81.8％)after ZNF148 knockdown,and increased(2.6 times)after SP5 overexpression.Transfection of si-SP5 and ZNF148 expression plasmids into A549 cells increased the mRNA expression of P53 by 6.6 times and 14.6 times,respectively.These results indicate that ZNF148 could activate,whereas SP5 could inhibit,P53 expression.The conserved cis-element of ZNF148 and SP5 TFs was found in the region of the P53 promoter by bioinformatics methods.The data from dual luciferase reporter gene assay showed that the luciferase activity of ZNF148 in Ishikawa and A549 cells was increased by 2.1-fold and 4.2-fold compared with the control group(P＜0.05).Compared with the control group,the normalized relative luciferase activity of transfected SP5 decreased by 77.1％and 35.7％(P＜0.05).However,when the cis-element of ZNF148 and SP5 was mutated,the effect disappeared.Further trans-fection of ZNF148 and SP5 with different ratios revealed that SP5 could reverse the transcriptional activa-tion of P53 by ZNF148.Studies have shown that ZNF148 shares a common site with SP5,and the ratio of the two TFs may influence the transcriptional activity of P53.The expression of the Wnt pathway and the cell proliferation rate after knockdown of ZNF148 and SP5 were further studied to explore the role of the two TFs.Our data show that ZNF148 and SP5 could regulate the transcriptional activity of P53,and their expression levels and interaction may be the key factors regulating P53 expression.

BACKGROUND: Congenital heart disease (CHD) is a leading cause of birth defect-related mortality. However, more recent CHD mortality data for China are lacking. Additionally, limited studies have evaluated sex, rural-urban, and region-specific disparities of CHD mortality in China. METHODS: We designed a population-based study using data from the Dataset of National Mortality Surveillance in China between 2008 and 2021. We calculated age-adjusted CHD mortality using the sixth census data of China in 2010 as the standard population. We assessed the temporal trends in CHD mortality by age, sex, area, and region from 2008 to 2021 using the joinpoint regression model. RESULTS: From 2008 to 2021, 33,534 deaths were attributed to CHD. The period witnessed a two-fold decrease in the age-adjusted CHD mortality from 1.61 to 0.76 per 100,000 persons (average annual percent change [AAPC] = -5.90%). Females tended to have lower age-adjusted CHD mortality than males, but with a similar decline rate from 2008 to 2021 (females: AAPC = -6.15%; males: AAPC = -5.84%). Similar AAPC values were observed among people living in urban (AAPC = -6.64%) and rural (AAPC = -6.12%) areas. Eastern regions experienced a more pronounced decrease in the age-adjusted CHD mortality (AAPC = -7.86%) than central (AAPC = -5.83%) and western regions (AAPC = -3.71%) between 2008 and 2021. Approximately half of the deaths (46.19%) due to CHD occurred during infancy. The CHD mortality rates in 2021 were lower than those in 2008 for people aged 0-39 years, with the largest decrease observed among children aged 1-4 years (AAPC = -8.26%), followed by infants (AAPC = -7.01%). CONCLUSIONS CHD mortality in China has dramatically decreased from 2008 to 2021. The slower decrease in CHD mortality in the central and western regions than in the eastern regions suggested that public health policymakers should pay more attention to health resources and health education for central and western regions.
