Birth growth curves of neonates in high-altitude areas: A cross-sectional study.

Background: Since the current commonly used birth growth curves are unsuitable for neonates in high-altitude areas; this study aimed to establish birth growth curves for full-term neonates residing at 2,000-3,000 m.

Methods: This cross-sectional study retrospectively analyzed the physical measurement data of 1,546 full-term neonates delivered at the Red Cross Hospital of Qinghai province, China, from July 2021 to April 2022. The percentile curves of birth weight, length, and head circumference of neonates of different gestational ages and genders were developed using curve fitting.

Role of miR-22 in intestinal mucosa tissues and peripheral blood CD4+ T cells of inflammatory bowel disease.

Objective: miR-22 is known to be involved in the pathogenesis of several autoimmune diseases, but it remains unclear whether miR-22 is associated with inflammatory intestinal disease (IBD).

Methods: The patients with ulcerative colitis (UC) and Crohn's disease (CD) were enrolled in this study. After the CD4+ T cells from healthy controls and active IBD patients were isolated and then transfected with miR-22 mimics/inhibitors, Quantitative real-time polymerase chain reaction (qRT-PCR) was conducted to measure expressions of miR-22, HDAC4, specific transcription factors in intestinal mucosa tissue and CD4+ T cells, while enzyme-linked immuno sorbent assay (ELISA) to detect expressions of inflammatory cytokines in PB.

Successful esophagectomy in a patient with combined esophageal cancer and hemophilia B.

Patients with esophageal cancer often require esophagectomy with esophagogastrostomy. However, the incidence of complications, such as hemorrhage, during operations for esophageal cancer is high, even with minimally invasive surgery. Without the appropriate interventions, the risk of major intraoperative and postoperative hemorrhage is very high in patients with esophageal cancer and hemophilia.

Successful surgical strategy in a late case of Boerhaave's syndrome.

Boerhaave's syndrome refers to the spontaneous transmural rupture of the esophagus. Primary repair may be performed in patients who present within 24 h of perforation, and such cases have the best outcomes as most complications have not yet developed. However, the treatment of late perforations remains controversial.

MicroRNA-214 provokes cardiac hypertrophy via repression of EZH2.

Micro RNAs are small, non-coding RNA molecules that regulate gene expression via either translational inhibition or mRNA degredation. Enhancer of zeste homolog 2 (EZH2)-mediated hypertrophic signaling is a major regulatory response to hypertrophic stimuli. In this study, we constructed AAC rat models and PE-induced hypertrophic cardiomyocytes.

Elevated intraoperative expression of ventricular myosin light chain predicts heart failure after valve replacement surgery.

Background: It can be difficult to predict which patients will survive and recover cardiac function after valve replacement surgery. We hypothesized that the expression levels of ventricular myosin light chain (MLCv) might reflect the severity of disease or the extent of irreversible myocardial damage and might be useful for predicting the postoperative course. Thus, the aim of this study was to explore the relationship between MLCv expression in specimens obtained during valve replacement surgery and the postoperative New York Heart Association (NYHA) class.

[Diagnosis and treatment of pulmonary histoplasmoma: report of 3 cases].

Objective: To investigate the diagnosis and treatment of pulmonary histoplasmoma.

Methods: The clinical data of 3 patients with pulmonary histoplasmoma. 2 males, both 49-years-old, and 1 female, 27-years-old, were analyzed.
