Study of height, sitting height, lower extremity length, and the prevalence of short stature among elementary school students in the Tianyuan District of Zhuzhou City.

In this study, the height, sitting height, lower extremity length, growth status, and body proportions of elementary school students aged 6 to 12 years in Tianyuan District of Zhuzhou City, China, were analyzed. A total of 41,156 children from 38 elementary schools in the Tianyuan District of Zhuzhou City were selected for height measurement, employing the cluster sampling method. After the cluster data were obtained, the height and sitting height information were extracted, and calculations were performed for lower extremity length, sitting height-to-lower extremity length ratio, and sitting height-to-height ratio.

A Case of Floating-Harbor Syndrome with "Growth and Language Development Delay" as Its Clinical Manifestation.

Background: Floating-Harbor syndrome (FHS) is a rare autosomal dominant inherited disease characterized primarily by short stature, delayed language development, and typical facial features. There are currently few case reports, diagnoses and treatments for these syndromes at home and abroad.

Case Description: This study reports a case of a boy with "growth and language development delay" as the predominant clinical manifestation.

A Case Report of Cardiofaciocutaneous Syndrome with Pathogenic Variant.

Craniofacial dysmorphism, cardiac abnormalities, ectodermal abnormalities, psychomotor delay, intellectual disability, and short stature are all hallmarks of the extremely rare disorder known as cardiofaciocutaneous syndrome (CFCS). Although CFCS is considered rare, approximately 300 cases have been documented in the literature. In this report, we discuss a patient diagnosed with CFCS without the typical heart malformations but with craniofacial features, skin abnormalities, intellectual disability, and short stature.

Case Report: A Novel Homozygous Mutation of Cyclin O Gene Mutation in Primary Ciliary Dyskinesia with Short Stature.

Background: Primary ciliary dyskinesia (PCD) is a group of autosomal recessive genetic diseases caused by abnormal ciliary ultrastructure and/or function, resulting in reduced ciliary clearance function or other dysfunctions. PCD is one of the causes of recurrent respiratory tract infections in children. At present, there is no gold standard for diagnosis.

Serum Fat-Soluble Vitamin Levels of 6,082 Minors in Zhuzhou City.

Objective: To explore the nutritional status of serum fat-soluble vitamins such as vitamin A, 25-hydroxyvitamin D, and vitamin E of minors in the Zhuzhou area to provide a scientific basis for clinical guidance to supplement fat-soluble vitamins reasonably.

Method: A total of 6,082 minors who underwent physical examination from January 2017 to February 2019 in the Children's Health Department of Zhuzhou Hospital affiliated with XiangYa School of Medicine of Central South University were selected as the subjects to measure the levels of serum fat-soluble vitamins A, D, and E.

Results: (1) Their average levels of serum vitamin A, 25-hydroxyvitamin D, and vitamin E were (0.

AlCl exposure regulates neuronal development by modulating DNA modification.

Background: As the third most abundant element, aluminum is widespread in the environment. Previous studies have shown that aluminum has a neurotoxic effect and its exposure can impair neuronal development and cognitive function.

Aim: To study the effects of aluminum on epigenetic modification in neural stem cells and neurons.

Hsa_circRNA_000166 Promotes Cell Proliferation, Migration and Invasion by Regulating miR-330-5p/ELK1 in Colon Cancer.

Introduction: Circular RNAs (circRNAs), a novel class of non-coding RNAs, which are widely expressed in human cells, have essential roles in the development and progression of cancers. The aim of this study is to figure out the role of circ_000166 in colon cancer (CC) development and the signaling pathway involved.

Materials And Methods: HT29 and HCT116 cells were transfected with siRNA of circRNA, miRNA mimics and inhibitors.

Inhibition of the proliferation, migration, and invasion of human breast cancer cells by leucine aminopeptidase 3 inhibitors derived from natural marine products.

Leucine aminopeptidase 3 is involved in the progression and metastasis of several cancers. This study aimed to screen anti-tumor lead compounds targeting leucine aminopeptidase 3. The compounds' suppression effect on enzyme activity and anti-tumor activity were evaluated through a series of assays.

A new method to evaluate the enzyme-suppressing activity of a leucine aminopeptidase 3 inhibitor.

The expression of leucine aminopeptidase 3 (LAP3) is associated with the prognosis for and malignant transformation of many types of tumors. Therefore, a LAP3 inhibitor may represent a new strategy for cancer therapy. Evaluating the suppression of enzyme activity by an LAP3 inhibitor is essential.

Aminopeptidase N inhibitor 4cc synergizes antitumor effects of 5-fluorouracil on human liver cancer cells through ROS-dependent CD13 inhibition.

Aminopeptidase N (APN, also known as CD13) is involved in cellular processes of various types of tumors and a potential anti-cancer therapeutic target. Here, we report the effect of an APN inhibitor 4cc in enhancing sensitivity of hepatocellular carcinoma (HCC) cell lines and xenograft model in response to 5-fluorouracil (5-FU) in vivo and in vitro. The treatment of the combination of 4cc with 5-FU, compared to the combination of bestain with 5-FU, markedly suppressed cell growth and induced apoptosis of HCC cells, accompanying the increase in the level of reactive oxygen species (ROS) and followed by a decrease in the mitochondrial membrane potential (ΔΨM).

Intrapulmonary shear stress enhancement: a new therapeutic approach in acute myocardial ischemia.

Objective: Ischemic heart disease (IHD) is a leading cause of mortality with insufficient results of current therapies, most probably due to maintained endothelial dysfunction conditions. Alternatively, we propose a new treatment that promotes endothelial shear stress (ESS) enhancement using an intrapulmonary pulsatile catheter.

Methods: Twelve piglets, divided in equal groups of 6: pulsatile (P) and non-pulsatile (NP), underwent permanent left anterior descending coronary artery ligation through sternotomy.

[Inhibitory effect of Astragalus polysaccharides on apoptosis of pancreatic beta-cells mediated by Fas in diabetes mellitus rats].

Objective: To observe the effects of Astragalus polysaccharides (APS) on the BG, insulin and C-peptide in serum, ultrastructure and Fas expression of pancreatic beta-cells in diabetes mellitus (DM) rats.

Methods: Thirty DM rats induced by streptozotocin (STZ) were randomly divided into three groups: DM group, APS 200 mg/kg group, APS 400 mg/kg group, another 10 normal rats were taken as the control group. The drug was given by intraperitoneal for 6 weeks.

Polysialylation promotes neural cell adhesion molecule-mediated cell migration in a fibroblast growth factor receptor-dependent manner, but independent of adhesion capability.

Polysialic acid (PSA), a carbohydrate polymer mainly present in the neural cell adhesion molecule (NCAM), promotes neural plasticity; however, its mode of action in tumor malignancy remains largely unknown. In this study, we investigated the influence of polysialylation on cell migration. PSA consistently promoted cell migration on different extracellular matrices (ECMs) but differentially affected cell adhesion.
