No variants were found among healthy controls. The variant c.467G > A (S156N) had increased protein expression and enhanced functionality compared with the wild type, without affecting the subcellular localization. The other variant, c.487C > T (P163S), did not show any abnormalities in protein expression or subcellular localization; however, it inhibited the transcriptional activities of downstream target genes and physically interacted with TBX5, another cardiac transcription factor. CONCLUSION Our results show that the S156N and P163S variants may affect the transcriptional function of KLF13 and physical interaction with TBX5. These results identified KLF13 as a potential genetic risk factor for congenital heart disease.BACKGROUND Colorectal cancer (CRC) ranks the third among the most common malignancies globally. It is well known that microRNAs (miRNAs) play vital roles in destabilizing mRNAs and repressing their translations in this disease. However, the mechanism of miRNA-induced mRNA cleavage remains to be investigated. METHOD In this study, high-throughput small RNA (sRNA) sequencing was utilized to identify and profile miRNAs from six pairs of colorectal cancer tissues (CTs) and adjacent tissues (CNs). Degradome sequencing (DS) was employed to detect the cleaved target genes. The Database for Annotation, Visualization and Integrated Discovery (DAVID) software was used for GO (Gene Ontology) and KEGG (Kyoto Encyclopedia of Genes and Genomes) pathway analysis. RESULTS In total, 1278 known miRNAs (clustered into 337 families) and 131 novel miRNAs were characterized in the CT and CN libraries, respectively. Of those, 420 known and eight novel miRNAs were defined as differentially expressed miRNAs (DEmiRNAs) by comparing thget genes in CRC.BACKGROUND This study sought to detect the expression and clinical significance of miR-4516 and miR-21-5p in serum of patients with colorectal cancer. METHODS Bioinformatics methods were used to analyze the expression patterns of miR-4516 and miR-21-5p in colorectal cancer. A total of 80 patients with colorectal cancer, 65 patients with benign colorectal tumors and 50 healthy persons were selected. qRT-PCR was performed to detect the expression levels of serum miR-4516 and miR-21-5p before and after operation or postoperative recurrence. The correlation of miR-4516 and miR-21-5p expression levels with the clinical characteristics and prognosis of colorectal cancer was analyzed, and that with the patient's survival was further examined by Kaplan-Meier analysis. RESULTS MiR-4516 was poorly expressed in colorectal cancer in the preoperative group, and miR-21-5p was highly expressed. While in the postoperative group, miR-4516 was up-regulated, and miR-21-5p was down-regulated. The low expression of miR-4516 was shown to be related to TNM staging, invasion degree, lymph node metastasis and distant metastasis of the patients. Whereas the high expression of miR-21-5p was proved to be correlated with TNM staging and lymph node metastasis. Kaplan-Meier survival analysis showed that high expression of miR-4516 or low expression of miR-21-5p could contribute to better overall survival. CONCLUSION Low miR-4516 or high miR-21-5p could be used as an independent risk factor for prognosis of colorectal cancer.BACKGROUND To determine the effects of previous placenta previa on the maternal and neonatal outcomes of the next pregnancy. METHODS This 10-year retrospective cohort study was conducted in the Department of Obstetrics and Gynecology, Third Affiliated Hospital of Guangzhou Medical University, between January 2009 and 2018. We retrospectively analyzed the effects of a previous singleton pregnancy in women with and without placenta previa on the outcomes of the subsequent pregnancy. To control for confounders, we used multiple logistic regression models. RESULTS A total of 57,251 women with singleton pregnancies gave birth during the 10-year study period. Among them, 6070 women had two consecutive births. For the first pregnancy, 1603 women delivered by cesarean delivery and 4467 by vaginal delivery. Among women with a history of cesarean delivery, placenta previa was an independent risk factor for hemorrhage (adjusted odds ratio [aOR] 2.25, 95% confidence interval [CI] 1.1-4.62), placenta accreta spectrum (PAS) disorders (aOR 4.11, 95% CI 1.68-10.06), and placenta previa (aOR 6.24, 95% CI 2.85-13.67) during the subsequent pregnancy. Puerperal infection, blood transfusion, and perinatal outcomes did not significantly differ between women with a history of placenta previa and women without this history. Among women with a history of vaginal delivery, placenta previa increased the risk of PAS disorders (aOR 5.71, 95% CI 1.81-18.03) and placenta previa (aOR 4.14, 95% CI 1.07-16.04) during the subsequent pregnancy. There was no significant difference between the two groups in terms of hemorrhage, blood transfusion, puerperal infection, and perinatal outcomes. CONCLUSIONS Women with a history of placenta previa are at risk for adverse outcomes such as postpartum hemorrhage, PAS disorders, and placenta previa in the subsequent pregnancy.BACKGROUND Bilateral medial medullary infarction (MMI) is uncommon and bilateral medial pons infarction (MPI) is even rarer. "Heart appearance" on magnetic resonance imaging (MRI) is a characteristic presentation of bilateral medial medullary infarction (MMI). CASE PRESENTATION We present 67-year-old Chinese diabetic and hypertensive female patient affected with "heart appearance-like" infarction in bilateral ponto-medullary junction on MRI. Abnormal signal was observed in the bilateral ponto-medullary junction on T1, T2, fluid-attenuated inversion recovery and apparent diffusion coefficient (ADC). The whole brain digital subtraction angiography (DSA) showed the basilar artery and vertebral artery remained intact. Therefore, we speculated that the bilateral ponto-medullary junction infarction might be caused by the deep perforating branch of the basilar artery. CONCLUSIONS As far as we know, the "heart appearance-like" infraction in bilateral ponto-medullary junction was not reported. ISRIB in vitro Our case also suggests that bilateral ischemic infraction involvement of the medulla and pon is possible even in the context of an intact basilar artery.
