Objective:To evaluate the clinical effect of high-intensity interval training and moderate continuous aerobic training on patients classified as low risk for exercise rehabilitation after a percutaneous coronary intervention (PCI).Methods:A total of 43 patients considered low-risk after a PCI were randomly divided into a high-intensity interval training group (HIIT group, 22 cases) and a moderate continuous aerobic training group (MCT group, 21 cases). The HIIT group received high-intensity, but aerobic interval training involving 8 rounds of 3 minutes of high-intensity exercise with 2-minute intervals at 80% of peak power over 40 minutes, 3 times a week. The MCT group trained continuously at 60% of peak power for the same duration. After 12 weeks both groups were given an ultrasound examination and a cardiopulmonary exercise test to assess their cardiac functioning and exercise endurance. The subjects′ life quality was evaluated and compared using some items from the SF-36 scale.Results:Before the training, no significant differences were observed in the average left ventricular ejection fraction, stroke volume, peak power, peak oxygen uptake, anaerobic threshold, physiological functioning, physical pain, general health or social functioning between the two groups. After the training significant improvement in all these indicators was observed in both groups, but compared with MCT group, the average left ventricular ejection fraction, stroke volume, peak power and peak oxygen uptake of the HIIT group were significantly better.Conclusions:High-intensity, aerobic interval training is superior to moderate but continuous aerobic training for improving the cardiac functioning and exercise endurance of patients suitable for exercise rehabilitation after a PCI. But there is no significant difference in their effect on the short-term quality of life.

Background:
Insulin regulates glucose homeostasis and has important effects on metabolism, cell growth, and differentiation. Depending on the cell type and physiological context, insulin signal has specific pathways and biological outcomes in different tissues and cells. For studying the signal pathway of insulin on glycolipid metabolism in porcine embryonic fibroblast (PEF), we used high-throughput sequencing to monitor gene expression patterns regulated by insulin.
Objectives:
The goal of our research was to see how insulin affected glucose and lipid metabolism in PEFs.
Methods:
We cultured the PEFs with the addition of insulin and sampled them at 0, 48, and 72 h for RNA-Seq analysis in triplicate for each time point.
Results:
At 48 and 72 h, 801 and 1,176 genes were differentially expressed, respectively. Of these, 272 up-regulated genes and 264 down-regulated genes were common to both time points. Gene Ontology analysis was used to annotate the functions of the differentially expressed genes (DEGs), the biological processes related to lipid metabolism and cell cycle were dominant. And the DEGs were significantly enriched in interleukin-17 signaling pathway, phosphatidylinositol-3-kinase-protein kinase B signaling pathway, pyruvate metabolism, and others pathways related to lipid metabolism by Kyoto Encyclopedia of Genes and Genomes enrichment analysis.
Conclusions
These results elucidate the transcriptomic response to insulin in PEF. The genes and pathways involved in the transcriptome mechanisms provide useful information for further research into the complicated molecular processes of insulin in PEF.

Objective To analyze plantar pressure features of patients in injured and healthy sides of the lower limbs under different walking conditions after the trimalleolar fracture surgery, and compare these characteristics with healthy subjects. Methods Twelve Trimalleolar fracture patients and twenty-three healthy subjects were recruited and their plantar pressure characteristics under different walking conditions were tested, including peak pressure, contact area and contact time percentage. Results Comparison between injured and healthy sides: during level walking, peak pressure of the 3rd-5th toe in the injured feet were smaller than those in the healthy sides; in inversion position, peak pressure and contact area of the 3rd-5th toe area in the injured feet were smaller than those in the healthy side; in eversion position, peak pressure, contact area and contact time of the 3rd-5th toe in the injured feet were smaller than those in the healthy sides, and peak pressures of the hindfoot area were larger than those in the healthy sides. Comparison between patients and healthy subjects: under three kinds of walking conditions, peak pressures of the 2nd and 3rd metatarsus bones, the 2nd toe, the 3rd-5th toe, contact area of the 1st-5th toe and contact time percentage of the 2nd toe, the 3rd-5th toe area were all smaller than those of healthy subjects, while contact time of the hindfoot and mid-foot area were all smaller than those of healthy subjects. Conclusions The plantar pressure characteristics of Trimalleolar fracture patients were asymmetrical. Compared with healthy subjects, the plantar pressure features of patients were abnormal during stance phase. Compared with healthy subjects, the motor control ability and stability of patients in eversion positions were decreased. The plantar pressure characteristics at ankle eversion can be used to evaluate ankle joint function.

Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.
