Foam dressing and micropower vacuum dressing promote diabetic foot ulcer wound healing by activating the PI3K/AKT/mTOR pathway in rats.

Foam dressing (FD) and micropower vacuum dressing (MVD) have been applied in the treatment of diabetic foot ulcer (DFU). However, research about the mode of action on the efficacy of the two dressings is extremely rare. This study proposed to explore the mechanism involved in diabetic wound healing under FD or MVD treatment.

Overexpression of forebrain PTP1B leads to synaptic and cognitive impairments in obesity.

Obesity has reached pandemic proportions and is a risk factor for neurodegenerative diseases, including Alzheimer's disease. Chronic inflammation is common in obese patients, but the mechanism between inflammation and cognitive impairment in obesity remains unclear. Accumulative evidence shows that protein-tyrosine phosphatase 1B (PTP1B), a neuroinflammatory and negative synaptic regulator, is involved in the pathogenesis of neurodegenerative processes.

A genome-wide association study identifies 25(OH)D3-associated genetic variants in the prediabetic Chinese population.

Objectives: Diabetes mellitus has been a significant public health problem, associated with high rates of morbidity, disability, and mortality. Prediabetes is a crucial period for preventing and managing diabetes. 25(OH)D3 is an important risk factor for prediabetes.

Contribution of body mass index, waist circumference, and 25-OH-D3 on the risk of pre-diabetes mellitus in the Chinese population.

This study aimed to investigate the associations between body mass index (BMI), waist circumference (WC), 25-hydroxy-vitamin D3 (25-OH-D3), and the risk of pre-diabetes mellitus (PDM), as well as their predictive values in identifying PDM. A total of 1688 participants were included in this cross-sectional investigation. Spearman's correlation analysis was used to assess the relationships between candidate indicators and PDM.

MRPS6 modulates glucose-stimulated insulin secretion in mouse islet cells through mitochondrial unfolded protein response.

Lack of efficient insulin secretion from the pancreas can lead to impaired glucose tolerance (IGT), prediabetes, and diabetes. We have previously identified two IGT-associated single nucleotide polymorphisms (SNPs) rs62212118 and rs13052524 located at two overlapping genes: MRPS6 and SLC5A3. In this study, we show that MRPS6 but not SLC5A3 regulates glucose-stimulated insulin secretion (GSIS) in primary human β-cell and a mouse pancreatic insulinoma β-cell line.

LASSO-based machine learning algorithm to predict the incidence of diabetes in different stages.

Background: Formal risk assessment is crucial for diabetes prevention. We aimed to establish a practical nomogram for predicting the risk incidence of prediabetes and prediabetes conversion to diabetes.

Methods: A cohort of 1428 subjects was collected to develop prediction models.

A pure 21q22.3 deletion in a 9-year-old boy with buried penis: a case report and literature review.

21q deletion has been associated with a wide range of clinical signs, from very mild to severe phenotypes, and with the progress of genetic technology, more patients with this deletion are being diagnosed. This study reports on a 9-year-old boy with a terminal deletion of 4.5 Mb on chromosome 21 in the locus of chr21: 43531239-48119895 (GRCh37/hg19).

An adolescent girl with premature ovarian failure, Graves' disease, and chronic urticaria: a case report.

Background: Premature ovarian failure is characterized by amenorrhea, hypoestrogenism, and hypergonadotropinism, and occurs in women under 40 years of age. The prevalence of premature ovarian failure in women younger than 20 years of age is only 0.01%.

-Related Maturity-Onset Diabetes of the Young (MODY12): A Report of a Chinese Family.

Maturity-onset diabetes mellitus of the young (MODY) is a monogenic diabetes characterized by autosomal dominant inheritance. Its atypical clinical features make diagnosis difficult and it can be misdiagnosed as type 1 or type 2 diabetes. Fourteen subtypes of MODY have been diagnosed so far, of which MODY12 is caused by mutation of the (ATP Binding Cassette Subfamily C Member 8) gene, which is rarely reported in China.

β-glucan attenuates cognitive impairment via the gut-brain axis in diet-induced obese mice.

Background: "Western" style dietary patterns are characterized by a high proportion of highly processed foods rich in fat and low in fiber. This diet pattern is associated with a myriad of metabolic dysfunctions, including neuroinflammation and cognitive impairment. β-glucan, the major soluble fiber in oat and barley grains, is fermented in the lower gastrointestinal tract, potentially impacting the microbial ecosystem and thus may improve elements of cognition and brain function via the gut-brain axis.

Curdlan Prevents the Cognitive Deficits Induced by a High-Fat Diet in Mice via the Gut-Brain Axis.

A high-fat (HF) diet is a major predisposing factor of neuroinflammation and cognitive deficits. Recently, changes in the gut microbiota have been associated with neuroinflammation and cognitive impairment, through the gut-brain axis. Curdlan, a bacterial polysaccharide widely used as food additive, has the potential to alter the composition of the microbiota and improve the gut-brain axis.

Oat-Derived β-Glucans Induced Trained Immunity Through Metabolic Reprogramming.

Trained immunity has been recently identified in innate immune cells, which undergo long-term epigenetic and metabolic reprogramming after exposure to pathogens for protection from secondary infections. (1, 3)/(1, 6)-β-glucan derived from fungi can induce potent trained immunity; however, the effect of (1, 3)/(1, 4)-β-glucan (rich in dietary fiber oat) on trained immunity has not been reported. In the present study, two cell culture systems for trained immunity induction were validated in monocytes/macrophages from mouse bone myeloid and human THP-1 cells exposed to positive inducers of trained immunity, including β-glucan from Trametes versicolor or human-oxidized low-density lipoprotein.

[Evidence-based medicine research on low-back pain with sham-acupuncture controlled design and the analysis on dynamic acupoint positioning].

To explore the positioning of acupoints, a research was done with PubMed for system reviews and clinical trials on treatment of low-back pain with sham-acupuncture controlled design from January 1, 2010 to October 27, 2017. Six system reviews and 12 sham-controlled acupuncture random trials were found. The statistical difference was not found in all the 6 trials with standard acupoint compared with the sham-acupuncture among the 8 penetrating skin sham-control trials.

Macrophage migration inhibitory factor as a novel cerebrospinal fluid marker for neurosyphilis among HIV-negative patients.

Background: Neurosyphilis (NS) is difficult to diagnose, especially in syphilis patients with negative cerebrospinal fluid (CSF) rapid plasma reagin (RPR) or Venereal Disease Research Laboratory (VDRL) tests.

Methods: We conducted a cross-sectional study and an analysis of macrophage migration inhibitory factor (MIF) in syphilitic patients to identify a novel marker for the diagnosis of NS, with a focus on probable NS (NS with negative VDRL/RPR tests). For this purpose, CSF and serum MIF concentrations were determined in 43 NS and 43 syphilis/non-NS (N-NS) patients at the Zhongshan Hospital of the Medical College of Xiamen University from July 2014 to June 2015.
