Changes in coagulation markers in children with Mycoplasma pneumoniae pneumonia and their predictive value for Mycoplasma severity.

Background: This study investigates the correlation between coagulation levels and the severity of Mycoplasma pneumoniae pneumonia (MPP) in children. In addition, the study analyses the predictive value of coagulation abnormalities in MPP combined with necrotising pneumonia (NP).

Methods: A total of 170 children with MPP who underwent treatment between June 2021 and February 2022 were selected for this study.

Toxic effects of Tripterygium glycoside tablets on the reproductive system of male rats by metabolomics, cytotoxicity, and molecular docking.

Background: Tripterygium glycoside tablets (TGT) is the most common preparation from Tripterygium wilfordii Hook F, which is widely used in clinical for treating rheumatoid arthritis (RA) and other autoimmune diseases. However, its serious reproductive toxicity limits its application.

Purpose: This study aimed to elucidate the toxic effects of TGT on the reproductive system of male RA rats and its potential toxic components and mechanism.

Case report: Surgical repair of congenitally corrected transposition of the great arteries with the guidance of three-dimensional printing.

A 10-year-old girl presented with obvious cyanosis, and the saturation of arterial blood oxygen (SpO) was decreased to 60.5% in the outpatient examination. Computed tomography angiography (CTA) and echocardiography suggested congenitally corrected transposition of the great arteries (ccTGAs), membranous ventricular septal aneurysm (MVSA), atrial septal defect (ASD), severe pulmonary stenosis (PS), and severe tricuspid regurgitation (TR).

An investigation of the time trends, risk factors, role of ultrasonic preoperative diagnosis of 79 ovarian pregnancy.

Background: Ovarian pregnancy (OP) is a rare form of ectopic pregnancy and is still a medical challenge. Therefore, more studies about the time trends, risk factors and diagnostic measurements are needed for the efficient treatment of OP.

Methods: The datum of OP patients who were treated at the Second Hospital of Hebei Medical University from 2003 to 2018 was collected and a retrospective cohort study was preformed between OP and tubal pregnancy.

Effects of microRNA-292-5p on myocardial ischemia-reperfusion injury through the peroxisome proliferator-activated receptor-α/-γ signaling pathway.

Ischemia-reperfusion injury (IRI) is a major cause of cardiac damage following various pathological processes, such as free radical damage and cell apoptosis. This study aims to investigate whether microRNA-292-5p (miR-292-5p) protects against myocardial ischemia-reperfusion injury (IRI) via the peroxisome proliferator-activated receptor (PPAR)-α/-γ signaling pathway in myocardial IRI mice models. Mouse models of myocardial IRI were established.

[Effects of ZFP580 on ventricular remodeling after myocardial ischemia/reperfusion in rats].

Objective: To investigate the relationship between zinc finger protein(ZFP580)and ventricular remodeling after myocardial is-chemia/reperfusion(I/R) injury in rats.

Methods: Seventy-two rats were divided into sham group and I/R groups which would be tested in se-ries time of 0.5 h, 1 h, 2 h, 4 h, 1 d,7 d,14 d,28 d after reperfusion to observe the expression of ZFP580 in rat myocardium.

Prognostic values of aldehyde dehydrogenase 1 isoenzymes in ovarian cancer.

Aldehyde dehydrogenase 1 (ALDH1) activity has been used as a functional stem cell marker to isolate cancer stem cells in different cancer types, including ovarian cancer. However, which ALDH1's isoenzymes are contributing to ALDH1 activity in ovarian cancer remains elusive. In addition, the prognostic value of an individual ALDH1 isoenzyme in ovarian cancer is not clear.

[Exploration of the association of H. pylori and EBV infection with cardiac and distal gastric adenocarcinoma among residents in Cixian County, a high-risk area of esophgeal cancer in Hebei province].

Objective: To evaluate the H. pylori and Epstein-Barr virus infection in cardiac and distal gastric adenocarcinoma tissues in residents in Cixian county, a high risk area of esophageal cancer in Hebei province, and to explore the putative role of H. pylori and Epstein-Barr virus infection in the carcinogenesis of adenocarcinoma at different subsites of stomach.

[The establishment of testicular fibrosis model in Wistar rats].

Objectives: To establish the testicular fibrosis model in rats.

Methods: Wistar rats were divided into control group(n = 12) and model group(n = 40) randomly. Testicular fibrosis model was built with the classical method of establishing experimental autoimmune orchitis (EAO) combined with injecting Bacille Calmette-Guerin (BCG) into left testis.
