Evidence shows that acupuncture-moxibustion could promote the healing of pressure injuries (PI), but its action mechanism is not fully understood. This review summarizes the basic research literature of acupuncture-moxibustion for PI and identifies that the mechanism of acupuncture-moxibustion for PI is related with regulation of related signaling pathway target proteins, improvement of inflammatory response, modulation of vascular microenvironment, attenuation of oxidative stress damage, and inhibition of cell apoptosis. The review also points out the current limitations and future research directions. It emphasizes the need for further exploration of the upstream regulatory mechanism, specific cellular molecules, and the interactions among these molecules. A multi-level, multi-target, and multi-dimensional approach is required to fully understand the mechanism underlying the promotion of PI healing by acupuncture-moxibustion.

BACKGROUND: This study commenced to uncover the role of long non-coding RNA FBXL19 antisense RNA 1 (FBXL19-AS1) in the development of ulcerative colitis (UC) and its possible mechanism. METHODS: FBXL19-AS1 expression in the colonic sigmoid mucosa of UC patients was detected. A colitis model was induced in mice using 5% dextran sodium sulfate. Hematoxylin–eosin staining was performed for histopathological examination. Apoptosis was detected by Tunel staining and tissue fibrosis was detected by immunohistochemistry. Also, intestinal permeability was examined. The concentrations of inflammatory factors IL-1b and IL-18 were detected by enzyme-linked immunosorbent assay. The relationship between FBXL19-AS1, miR-339-3p and RHOB was verified by RNA immunoprecipitation assay and dual luciferase reporter assay. RESULTS: The expression of FBXL19-AS1 was increased in dextran sodium sulfate (DSS)-induced colitis mouse model. FBXL19-AS1 interference or miR-339-3p overexpression inhibited DSS-induced colonic epithelial cell apoptosis and inflammatory response, and improved intestinal epithelial barrier defects, thereby ameliorating DSS-induced colitis injury in mice. FBXL19-AS1 sponged miR-339-3p while miR-339-3p targeted RHOB. Overexpression of RHOB reversed the protective effect of inhibition of FBXL19-AS1 on DSS-induced colitis in mice. CONCLUSION FBXL19-AS1 reduces miR-339-3p-mediated targeting of RHOB and aggravates intestinal epithelial barrier defect in DSS-induced colitis in mice.

Objective: To explore the heterogeneity and correlation of clinical phenotypes and genotypes in children with disorders of sex development (DSD). Methods: A retrospective study of 1 235 patients with clinically proposed DSD in 36 pediatric medical institutions across the country from January 2017 to May 2021. After capturing 277 DSD-related candidate genes, second-generation sequencing was performed to analyzed the heterogeneity and correlation combined with clinical phenotypes. Results: Among 1 235 children with clinically proposed DSD, 980 were males and 255 were females of social gender at the time of initial diagnosis with the age ranged from 1 day of age to 17.92 years. A total of 443 children with pathogenic variants were detected through molecular genetic studies, with a positive detection rate of 35.9%. The most common clinical phenotypes were micropenis (455 cases), hypospadias (321 cases), and cryptorchidism (172 cases) and common mutations detected were in SRD5A2 gene (80 cases), AR gene (53 cases) and CYP21A2 gene (44 cases). Among them, the SRD5A2 mutation is the most common in children with simple micropenis and simple hypospadias, while the AMH mutation is the most common in children with simple cryptorchidism. Conclusions: The SRD5A2 mutation is the most common genetic variant in Chinese children with DSD, and micropenis, cryptorchidism, and hypospadias are the most common clinical phenotypes. Molecular diagnosis can provide clues about the biological basis of DSD, and can also guide clinicians to perform specific clinical examinations. Target sequence capture probes and next-generation sequencing technology can provide effective and economical genetic diagnosis for children with DSD.

With the increasing incidence of hepatobiliary diseases, it is particularly important to understand the role of molecular, cellular and physiological factors in the clinical diagnosis and treatment with traditional Chinese medicine(TCM) in the development of liver disease. Appropriate animal models can help us identify the possible mechanisms of relevant diseases. Danio rerio(zebrafish) model was traditionally used to study embryonic development, and has been gradually used in screening and evaluation of liver diseases and relevant drug in recent years. Zebrafish embryos develop rapidly and the digestive organs of 5-day-old juvenile fish are all mature. At this stage, they may develop hepatobiliary diseases induced by developmental defects or compounds. Zebrafish liver is similar to human liver in cell composition, function, signal transduction, response to injury and cell process mediating liver disease. Furthermore, due to the high conservation of genes and proteins between humans and zebrafish, zebrafish becomes an alternative system for studying basic mechanisms of liver disease. Therefore, genetic screening could be performed to identify new genes involving specific disease processes, and chemical screening could be made for drugs in specific processes. This paper briefly introduced the experimental properties of zebrafish as model system, emphasized the study progress of zebrafish models for pathological mechanism of liver diseases, especially fatty liver, and drug screening and evaluation, so as to provide ideas and techniques for the future liver toxicity assessment of TCM.

OBJECTIVE: To investigate the therapeutic effects and mechanisms of Bianyanning on acute pharyngitis in rats, and to provide evidence and experimental data for its clinical application. METHODS: The acute pharyngitis of rats was induced by spraying ammonia directly to their throat. The model rats were randomly divided into model control group, the high-, medium- and low-dose group of Bianyanning, while normal rats were used as control group, 10 in each group. After the corresponding drug treatment, the symptoms and manifestations of each group were observed and recorded; 24 hours after last gavaging, blood samples of each group were collected from the abdominal aorta. The serum contents of interleukin 1-beta (IL-1β) and tumor necrosis factor alpha (TNF-α) were detected by ELISA. HE method was used to observe the characteristic of the lung tissues and the transmission electron microscopy method was used to observe the trachea cilia. RESULTS: After the treatment, compared with the model control group, the high-, medium- and low-dose group of Bianyanning, the symptoms of acute pharyngitis such as inflamed and congestive throat were relieved obviously. The morphological changes of lung and bronchus tissues were apparently improved. The contents of IL-1β and TNF-α in serum were decreased significantly. CONCLUSION Compound Bianyanning can promote the recovering process of acute pharyngitis, improve the morphology of lungs and bronchus, which may be related to inhibiting the releasing of the IL-1β and TNF-α in serum.
