[Application of ultrasound in treating postpartum pubis symphysis diastasis by bone setting manipulation].

Objective: To explore application value of ultrasound in treating postpartum pubis symphysis diastasis by bone setting manipulation.

Methods: Retrospective analysis was performed on 30 patients (case group) with postpartum pubis symphysis diastasis diagnosed in Wangjing Hospital, China Academy of Chinese Medical Sciences from June 2017 to January 2021, aged from 21 to 43 years old, with an average of (33.0±3.

Preterm neonate with a large congenital hemangioma on maxillofacial site causing thrombocytopenia and heart failure: A case report.

Background: We report a rare case of a large congenital hemangioma (CH) in the maxillofacial region in a female neonate that caused thrombocytopenia and heart failure. With close multidisciplinary collaboration, the congenital hemangioma was successfully resected with good results.

Case Summary: The patient was delivered at gestational age of 36 wk by cesarean section due to cephalopelvic disproportion and lack of onset of labor (birth weight: 2630 g).

[The role of miRNA in kidney development].

MicroRNAs (miRNAs) are endogenous small non-coding RNAs (19-25 nucleotides) that negatively regulate gene expression at the post transcriptional level by binding to complementary target sequences in the target mRNA. miRNAs play an important role in a wide range of biological processes, including organ development. Recent studies have shown that some miRNAs are highly expressed in the kidney and are closely related to kidney development and diseases, suggesting that miRNAs are important regulators in kidney physiology and pathology.

Alternatively Polarized Macrophages Regulate the Growth and Differentiation of Ependymal Stem Cells through the SIRT2 Pathway.

Ependymal stem cells (EpSCs) are dormant stem cells in the adult spinal cord that proliferate rapidly and migrate to the site of injury after spinal cord injury (SCI). Although they can differentiate into neurons under appropriate conditions in vitro, EpSCs mainly differentiate into astrocytes in vivo. Our previous study confirmed that alternatively polarized macrophages (M2) facilitate the differentiation of EpSCs towards neurons, but the detailed mechanism remains elusive.

[Clinical value of DC and DRs in warning sudden cardiac death of patients with coronary artery disease].

Objective: To make risk stratification of aged patients with coronary artery disease by deceleration capacity of rate (DC) and heart rate deceleration runs (DRs) and to investigate the value of the two detection technologies in warning sudden cardiac death.

Methods: Two hundrend and eighteen patients diagnosed with coronary artery disease (CAD) by coronary angiography (CAG) were selected as observa-tion group:including 55 patients with latent coronary artery disease (LCHD), 56 patients with acute myocardial infarction (AMI), 53 patients with angina pectoris (AP), 54 patients with ischemic heart failure. Fifty-five healthy controls in our hospital were selected at the same time (control group).

[Effects of different anesthesia methods on perioperative hemodynamics and ECG in old CHD patients].

Objective: To explore an optimal anesthesia method with less impact on hemodynamics and electrocardiogram (ECG) of old patients with coronary artery disease (CHD) during abdominal operation.

Methods: The 133 CHD patients waiting for abdominal operation were randomly divided into continuous epidural anesthesia (EA) group, general anesthesia group (GA) and combined spinal-epidural anesthesia (CSEA) group. Continuous monitoring was carried out during operation and mean arterial pressure (MAP), heart rate (HR), oxygen saturation (SaO2), abnormal ECG were measured respectively at different time for comparison and the differences of the above hemodynamic parameters and abnormal ECG features were compared among the 3 groups.

[The role of nitric oxide on the dysfunction of intestinal motility in rats subjected to hemorrhagic shock].

Objective: To determine the role of nitric oxide (NO) in intestinal motility dysfunction in rats subjected to hemorrhagic shock (HS).

Methods: Sixteen male Wistar rats were randomly and equally divided into two groups. The HS model of rat was induced by bleeding from femoral artery.

[Effects of mild hypothermia on low cardiac output after cardiac surgery].

Objective: To evaluate the effectiveness of mild hypothermia on low cardiac output in patients after cardiac surgery.

Methods: Twelve patients manifesting low cardiac output after cardiac surgery despite of the use of massive doses of catecholamine and intra-aortic balloon pump (IABP) underwent mild hypothermia during May 2009 to February 2011. Changes in hemodynamic parameters of the patients were measured, including cardiac index (CI),mixed venous oxygen saturation [SvO(2)] and urine volume.
