Background:
Hearing loss (HL) is one of the most common sensory disorders,
affecting over 5-8% of the world's population. Approximately half of HL cases are
attributed to genetic factors. In hereditary deafness, about 75-80% is inherited
through autosomal recessive inheritance, and common pathogenic genes include
GJB2 and SLC26A4. Pathogenic variants in the SLC26A4gene are the leading
cause of hereditary hearing loss in humans, second only to the GJB2 gene. Variants in the SLC26A4gene cause hearing loss, which can be non-syndromic autosomal recessive deafness (DFNB4, OMIM #600791) associated with enlarged
vestibular aqueduct (EVA) or Pendred syndrome (Pendred, OMIM #605646).
DFNB4 is characterized by sensorineural hearing loss combined with EVA or less
common cochlear malformation defect. Pendred syndrome is characterized by bilateral sensorineural hearing loss with EVA and an iodine defect that can lead to
thyroid goiter. Currently, it is known that EVA is associated with variants in the
SLC26A4 gene and is a penetrant feature of SLC26A4-related HL. Predominant
mutations in these genes differ significantly across populations. For instance, predominant SLC26A4 mutations differ among populations, including p.T416P and
c.1001G>A in Caucasians, p.H723R in Japanese and Koreans, and c.919-2A>G
in Han Taiwanese and Han Chinese. On the other hand, there has been no study
of hearing loss related to SLC26A4 gene variants among Mongolians, which is the
basis of our research.
Aim:
We aimed to identify the characteristics of the SLC26A4 gene variants in
Mongolian people with Enlarged vestibular aqueduct and Mondini malformation.
Materials and Methods:
In 2022-2024, We included 13 people with hearing loss
and enlarged vestibular aqueduct, incomplete cochlea (1.5 turns of the cochlea
with cystic apex- incomplete partition type II- Mondini malformation) were examined by CT scan of the temporal bone in our study. WES (Whole exome sequencing) analysis was performed in the Genetics genetic-laboratory of the National
Taiwan University Hospital.
Results:
Genetic analysis revealed 26 confirmed pathogenic variants of bi-allelic
SLC26A4 gene of 8 different types in 13 cases, and c.919-2A>G variant was dominant with 46% (12/26) in allele frequency, and c.2027T>A (p.L676Q) variant 19%
(5/26), c.1318A>T(p.K440X) variant 11% (3/26), c.1229C>T (p.T410M) variant 8%
(2/26) ) , c.716T>A (p.V239D), c.281C>T (p.T94I), c.1546dupC, and c.1975G>C
(p.V659L) variants were each 4% (1/26)- revealed. Two male children, 11 years
old (SLC26A4: c.919-2A>G) and 7 years old (SLC26A4: c.919-2A>G:, SLC26A4:
c.2027T>A (p.L676Q))had history of born normal hearing and progressive hearing
loss.
Conclusions
1. 26 variants of bi-allelic SLC26A4 gene mutation were detected
in Mongolian people with EVA and Mondini malformation, and c.919-2A>G was
the most dominant allele variant, and rare variants such as c.1546dupC, c.716T>A
(p.V239D) were detected.
2. Our study shows that whole-exome sequencing (WES) can identify gene
mutations that are not detected by polymerase chain reaction (PCR) or NGS analysis.

ObjectiveTo explore the regulation of Shaoyaotang on glucose metabolism reprogramming of macrophages and the mechanism of this decoction in inhibiting macrophage polarization toward the M1 phenotype. MethodsHuman monocytic leukemia-1 (THP-1) cells were treated with 100 ng·L-1 phorbol myristate acetate for induction of macrophages as the normal control group. The cells treated with 100 ng·L-1 lipopolysaccharide combined with 20 ng·L-1 interferon (IFN)-γ for induction of M1-type macrophages were taken as the M1 model group. M1-type macrophages were treated with the blank serum, Shaoyaotang-containing serum, 0.5 mol·L-1 2-deoxy-D-glucose (2-DG), and Shaoyaotang-containing serum + 2-DG, respectively. After intervention, the expression of CD86 and CD206 was examined by flow cytometry. The levels of interleukin (IL)-6, tumor necrosis factor (TNF)-α, IL-10, and transforming growth factor (TGF)-β were assessed by ELISA. Real-time PCR and Western blot were employed to determine the mRNA and protein levels, respectively, of hypoxia-inducible factor-1 alpha (HIF-1α), glucose transporter 1 (GLUT1), hexokinase 2 (HK2), glyceraldehyde-3-phosphate dehydrogenase (GAPDH), and 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase 3 (PFKFB3). ResultsCompared with that in the normal control group, the expression of CD86, the marker of M1-type macrophages, increased in the M1 model group and blank serum group (P<0.01), which indicated that the M1 inflammatory model was established successfully. In addition, the M1 model group was observed with up-regulated mRNA and protein levels of proinflammatory cytokines IL-6 and TNF-α and glycolysis-related factors HIF-1α, GLUT1, HK2, GAPDH, and PFKFB3 (P<0.01). Compared with the M1 model group, the Shaoyaotang-containing serum, 2-DG, and combined intervention groups showed decreased expression of CD86 (P<0.01), down-regulated mRNA and protein levels of proinflammatory factors IL-6 and TNF-α and glycolysis-related factors HIF-1α, GLUT1, HK2, GAPDH, and PFKFB3 produced by M1-type macrophages (P<0.01), increased expression of CD206 (marker of M2-type macrophages) (P<0.01), and elevated levels of IL-10 and TGF-β produced by M2-type macrophages (P<0.01). ConclusionShaoyaotang inhibits macrophage differentiation toward pro-inflammatory M1-type macrophages and promotes the differentiation toward anti-inflammatory M2-type macrophages by regulating glucose metabolism reprogramming. The evidence gives insights into new molecular mechanisms and targets for the treatment of ulcerative colitis with Shaoyaotang.

In recent years, as the incidence of ulcerative colitis (UC) is growing, intestinal mucosal injury has garnered increasing attention, and it is characterized by high recurrence, risk of inflammation-cancer transformation, and difficulty in repair. Intestinal mucosal injury in UC is centered on persistent inflammation and barrier dysfunction, with its pathological mechanisms involving endoplasmic reticulum stress (ERS)-mediated changes such as abnormal apoptosis, abnormal autophagy, and inflammatory responses. ERS induces apoptosis of intestinal epithelial cells, disrupts tight junction proteins, and exacerbates inflammatory responses through pathways such as protein kinase R-like endoplasmic reticulum kinase (PERK), inositol-requiring enzyme 1 alpha (IRE1α), and activating transcription factor 6 (ATF6), ultimately causing intestinal mucosal injury. Traditional Chinese medicine (TCM) has a long history of research on UC. The theory of sores depending on spleen-earth holds that spleen deficiency is the fundamental cause of UC, while pathological products such as dampness-turbidity and blood stasis are the secondary manifestations. Dysfunction of the spleen-earth leads to insufficient production and transformation of Qi and blood, malnutrition of the intestinal mucosa, and invasion of external pathogens. In the active phase of UC, spleen deficiency is often accompanied by excessive pathogenic factors such as dampness-heat and heat-toxin, leading to acute intestinal mucosal damage. In the remission phase, however, it is mainly characterized by spleen deficiency and healthy Qi deficiency, accompanied by residual pathogens, resulting in weak intestinal mucosal repair. Studies have shown that the endoplasmic reticulum, as a key site for protein synthesis and folding, has functions highly similar to the TCM concept of the spleen governing transportation and transformation. From a TCM perspective, the endoplasmic reticulum can be regarded as the carrier of spleen transportation, and ERS is a microcosmic manifestation of spleen dysfunction, leading to intestinal mucosal injury. ERS impairs the structure and function of the endoplasmic reticulum, induces the generation of abnormal Qi, and triggers pathological changes, making inflammation difficult to be reduced and causing the aggravation of ERS, forming a vicious cycle of spleen deficiency-pathological products-intestinal injury. TCM has unique advantages in regulating ERS to prevent and treat intestinal mucosal injury. According to the theory of sores depending on spleen-earth and the modern medical understanding of ERS, this paper delves into the TCM and Western medicine pathogenesis of intestinal mucosal injury in UC. Furthermore, this paper discusses the roles of TCM active components and compound formulas in reducing intestinal mucosal injury in UC by regulating ERS under the guidance of the treatment principles of invigorating the spleen and replenishing Qi as the key and dispelling dampness and removing blood stasis as the supplementation, aiming to provide new ideas and methods for the prevention and treatment of UC.

Lung cancer is one of the most common and deadliest cancers globally, with its incidence and mortality rates rising each year. Therefore, finding new, safe, and effective alternative therapies poses a significant research challenge in this field. Programmed cell death refers to the process by which cells actively self-destruct in response to specific stimuli, regulated by genetic mechanisms. Modern research indicates that dysregulation of programmed cell death is widespread in the occurrence and progression of lung cancer, allowing cancer cells to evade death while continuing to proliferate and metastasize. Thus, inducing the death of lung cancer cells can be considered a novel therapeutic strategy for treating the disease. In recent years, research on traditional Chinese medicine(TCM) in the field of oncology has gained widespread attention, becoming a focal point. An increasing number of studies have demonstrated that TCM can inhibit the progression of lung cancer and exert anti-cancer effects by inducing apoptosis, necroptosis, pyroptosis, autophagy, and ferroptosis. This paper provided a comprehensive review of the molecular mechanisms of programmed cell death in lung cancer, along with the potential mechanisms and research advancements related to the regulation of these processes by TCM, so as to establish a theoretical foundation and direction for future basic and clinical research on lung cancer.

Traditional Chinese medicine(TCM) is the pillar for the development of motherland medicine, and animal medicine has a long history of application in China, characterized by wide resources, strong activity, definite efficacy, and great benefits. It has significant potential and important status in the consumption market of raw materials of TCM. In the context of global climate change, farming system alterations, and low renewability, the depletion of wild medicinal animal resources has accelerated. Accordingly, the conservation and sustainable utilization of wild resources of animal medicinal materials has become a problem that garners increasing attention and urgently needs to be solved. This paper summarizes the current situation of domestic and foreign medicinal animal breeding and research progress in industrial application in recent years and points out the issues related to standardized breeding, germplasm selection and breeding, and quality evaluation standards for medicinal animals. Furthermore, this paper discusses standardized breeding, quality standards, resource protection and utilization, and the search for alternative resources for rare and endangered medicinal animals. It proposes that researchers should systematically carry out in-depth basic research on animal medicine, improve the breeding scale and level of medicinal animals, employ modern technology to enhance the quality standards of medicinal materials, and strengthen the research and development of alternative resources. This approach aims to effectively address the relationship between protection and utilization and make a significant contribution to the sustainable development of medicinal animal resources and the animal-based Chinese medicinal material industry.
