Research progress on the application of Chinese herbal medicine in anal fistula surgery.

Anal fistula is a rapidly developing anorectal disease that can lead to anal dysfunction if left untreated. Minimally invasive surgery is an important treatment option for anal fistula, as it can reduce the risk of anal sphincter injury and protect anal function. However, postoperative complications such as infection, pain, bleeding, edema, and fat liquefaction can occur, resulting in slow wound healing thus negatively impacting the patient's quality of life.

Targeted mutagenesis in mice via an engineered AsCas12f1 system.

SpCas9 and AsCas12a are widely utilized as genome editing tools in human cells, but their applications are largely limited by their bulky size. Recently, AsCas12f1 protein, with a small size (422 amino acids), has been demonstrated to be capable of cleaving double-stranded DNA protospacer adjacent motif (PAM). However, low editing efficiency and large differences in activity against different genomic loci have been a limitation in its application.

X-ray-downregulated nucleophosmin induces abnormal polarization by anchoring to G-actin.

Ionizing radiation poses significant risks to astronauts during deep space exploration. This study investigates the impact of radiation on nucleophosmin (NPM), a protein involved in DNA repair, cell cycle regulation, and proliferation. Using X-rays, a common space radiation, we found that radiation suppresses NPM expression.

Large-scale ORF screening based on LC-MS to discover novel lncRNA-encoded peptides responding to ionizing radiation and microgravity.

In the human genome, 98% of genes can be transcribed into non-coding RNAs (ncRNAs), among which lncRNAs and their encoded peptides play important roles in regulating various aspects of cellular processes and may serve as crucial factors in modulating the biological effects induced by ionizing radiation and microgravity. Unfortunately, there are few reports in space radiation biology on lncRNA-encoded peptides below 10kD due to limitations in detection techniques. To fill this gap, we integrated a variety of methods based on genomics and peptidomics, and discovered 22 lncRNA-encoded small peptides that are sensitive to space radiation and microgravity, which have never been reported before.

The Tumorigenic Effect of lncRNA AFAP1-AS1 is Mediated by Translated Peptide ATMLP Under the Control of m A Methylation.

Long noncoding RNAs (lncRNAs) in eukaryotic transcripts have long been believed to regulate various aspects of cellular processes, including carcinogenesis. Herein, it is found that lncRNA AFAP1-AS1 encodes a conserved 90-amino acid peptide located on mitochondria, named lncRNA AFAP1-AS1 translated mitochondrial-localized peptide (ATMLP), and it is not the lncRNA but the peptide that promotes the malignancy of nonsmall cell lung cancer (NSCLC). As the tumor progresses, the serum level of ATMLP increases.

Observation on the Efficacy of Shouhui Tongbian Capsule in the Treatment of Functional Constipation and Study on Its Regulatory Effect on Intestinal Flora.

Functional constipation is relatively common in both adults and children, exhibiting similar symptoms. However, there are significant differences in the epidemiology, symptomatology, pathophysiology, diagnostic tests, and treatment management of functional constipation by age. The treatment of functional constipation is generally based on lifestyle interventions, pelvic floor interventions, and pharmacotherapy.

Comparison of the Effects of Essential Oil Obtained from the Crude and Bran-Processed on Lipopolysaccharide-Induced Inflammatory Injury of Human Colonic Epithelial Cells by Downregulating the IKK/NF-B Signaling Pathway.

Background: (AL) has been used in traditional Chinese medicine for the treatment of various diseases including digestive disorders. Ulcerative colitis (UC) is a common digestive system disease with a low cure rate and easy recurrence. However, it is still not clear whether AL is suitable for UC treatment.
