ObjectiveTo investigate the therapeutic effect and mechanism of Huatan Qushi Huoxue prescription on rats with metabolic dysfunction-associated steatohepatitis (MASH). MethodsA total of 60 specific pathogen-free Sprague-Dawley rats were randomly divided into blank control group, model A group, model B group, Western medicine group (polyene phosphatidylcholine, 143.64 mg/kg), high-dose Chinese medicine group (Huatan Qushi Huoxue prescription, 20.16 g/kg), and middle-dose Chinese medicine group (Huatan Qushi Huoxue prescription, 10.08 g/kg). All rats except those in the blank control group were given high-fat diet. Samples were collected from the model A group at week 8, and since week 12, the other groups were given the corresponding drug once a day for 8 consecutive weeks, with samples collected at week 20. Body weight, liver wet weight, and liver index were measured for all rats; the microplate method was used to measure the serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and free fatty acids (FFA); ELISA was used to measure the serum levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), interleukin-6 (IL-6), and soluble triggering receptor expressed on myeloid cells 2 (sTREM2); HE staining and oil red O staining were performed to observe liver histopathological changes; immunofluorescence assay was used to measure CD68+TREM2+ cells in liver tissue and calculate the phagocytosis rate of macrophages; quantitative real-time PCR was used to measure the mRNA expression levels of sphingosine 1-phosphate (S1P), sphingosine 1-phosphate receptor 1 (S1PR1), a disintegrin and metalloproteinase 17 (ADAM17), and triggering receptor expressed on myeloid cells 2 (TREM2) in liver tissue, and immunohistochemistry was used to measure the protein expression levels of S1P, S1PR1, ADAM17, and TREM2 in liver tissue. A one-way analysis of variance was used for comparison of normally distributed continuous data with homogeneity of variance between groups, and the least significant difference t-test was used for further comparison between two groups; the Welch’s test was used for comparison of normally distributed continuous data with heterogeneity of variance between groups, and the Tamhane’s test was used for further comparison between two groups. The Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between groups, and the Dunn’s test was used for further comparison between two groups. ResultsCompared with the blank control group, the model A group and the model B group had significant increases in body weight and liver wet weight, and the model B group had a significant increase in liver index (all P<0.05). HE staining showed diffuse macrovesicular steatosis of liver tissue in the model A group and a large number of hepatocytes with ballooning degeneration in liver tissue in the model group B, with the presence of mixed inflammatory cell infiltration and mild perisinusoidal fibrosis in the lobules and the portal area. Compared with the blank control group, the model A group and the model B group had significant increases in NAS score and oil red O-positive area (all P<0.05), and the model B group had significant increases in these two indicators than the model A group (both P<0.05). Compared with the blank control group, the model A group and the model B group had significant increases in the serum levels of TC, TG, LDL-C, FFA, IL-1β, IL-6, and sTREM2 and a significant reduction in the serum level of HDL-C, and the model B group had significant increases in the serum levels of ALT, AST, and TNF-α (all P<0.05); compared with the model A group, the model B group had significant increases in the serum levels of ALT, AST, TC, TG, FFA, TNF-α, IL-1β, IL-6, and sTREM2 and a significant reduction in the serum level of HDL-C (all P<0.05). Immunofluorescence assay showed that compared with the blank control group, the model A group had a significant increase in the phagocytosis rate of macrophages (P<0.05), while the model B group had a significantly lower phagocytosis rate of macrophages than the model A group (P<0.05). Quantitative real-time PCR showed that compared with the blank control group, the model A group and the model B group had a significant increase in the mRNA expression level of TREM2, and the model B group had significant increases in the mRNA expression levels of S1P and S1PR1 (both P<0.05); moreover, compared with the model A group, the model B group had significant increases in the mRNA expression levels of S1PR1 and TREM2 (both P<0.05). Immunohistochemistry showed that compared with the blank control group, the model A group and the model B group had significant increases in the protein expression levels of S1P, S1PR1, and ADAM17, and the model A group had a significant increase in the protein expression level of TREM2 (all P<0.05); compared with the model A group, the model B group had significant increases in the protein expression levels of S1P, S1PR1, and ADAM17 and a significant reduction in the protein expression level of TREM2 (all P<0.05). Compared with the model B group, each medication group had significant reductions in body weight, liver wet weight, and liver index (all P<0.05); each medication group had significant improvements in hepatic steatosis and inflammatory damage, with significant reductions in NAS score and oil red O-positive area (all P<0.05); each medication group had significant reductions in the serum levels of ALT, AST, TC, TG, FFA, IL-1β, and IL-6 (all P<0.05) and a significant increase in the serum level of HDL-C (P<0.05), and the high-dose Chinese medicine group had a significant reduction in the serum level of TNF-α (P<0.05); each medication group had a significant increase in the phagocytosis rate of macrophages (all P<0.05); the high- and middle-dose Chinese medicine groups had a significant reduction in the protein expression level of ADAM17, and the high-dose Chinese medicine group had a significant increase in the protein expression level of TREM2 (all P<0.05). ConclusionHuatan Qushi Huoxue prescription improves lipid metabolism and inflammation in the liver of MASH rats by regulating hepatic macrophage phagocytosis.

OBJECTIVE To focus on the classic NOD-like receptor protein 3 (NLRP3)/Caspase-1/gasdermin D (GSDMD) pyroptosis pathway and explore the mechanism by which Huatan qushi huoxue formula (HQHF) inhibits macrophage pyroptosis to ameliorate metabolic dysfunction-associated steatohepatitis (MASH). METHODS RAW264.7 cells were divided into 5 groups: Control group (10% blank serum), Model group [10% blank serum+5 μg/mL lipopolysaccharide (LPS)], HQHF-L group (2.5% drug-containing serum+7.5% blank serum+5 μg/mL LPS), HQHF-M group (5% drug-containing serum+5% blank serum+5 μg/mL LPS), and HQHF-H group (10% drug-containing serum+5 μg/mL LPS). After 24 h of routine culture post-administration, cells and supernatants were collected for assays. Cell morphology was observed via scanning electron microscopy and phase-contrast microscopy; localization and expression of gasdermin D-N (GSDMD-N) were observed by immunofluorescence. Interleukin-1β (IL-1β) and IL-18 contents in supernatants were detected by ELISA; mRNA and protein expressions of NLRP3, Caspase-1, and GSDMD were measured using real-time PCR and Western blot. RESULTS Compared with the Control group, the Model group showed typical pyroptotic morphology (cell membrane bulging and pore formation), increased aggregation and fluorescence intensity of GSDMD-N on the cell membrane ( P <0.05), significantly increased the contents of IL-1β and IL-18 in cell supernatants ( P <0.05), and significantly up-regulated mRNA and protein expressions of NLRP3, Caspase-1, and GSDMD in cells ( P <0.05). Compared with the Model group, the HQHF-L, HQHF-M and HQHF-H groups showed improved pyroptotic morphology, reduced membrane localization and significantly weakened fluorescence intensity of GSDMD-N ( P <0.05), significantly decreased the contents of IL-1β and IL-18 in cell supernatants ( P <0.05), and significantly down-regulated mRNA and protein expressions of NLRP3, Caspase-1, and GSDMD in cells ( P <0.05). CONCLUSIONS HQHF inhibits LPS-induced macrophage pyroptosis, and its mechanism of improving MASH may be associated with the suppression of the activation of the classical NLRP3/Caspase-1/GSDMD pyroptosis pathway.

Liver fibrosis is the core pathological stage of the progression of various chronic liver diseases to liver cirrhosis, and hepatic stellate cell (HSC) activation and the abnormal accumulation of collagen fibers are important processes for the development and progression of liver fibrosis. In recent years, studies have shown that HSC activation is regulated by the complex interactions between various organelles (including mitochondria, endoplasmic reticulum, Golgi apparatus, lysosome, and peroxisomes), and such interactions affect the key cellular processes such as energy metabolism, protein synthesis and folding, reactive oxygen species balance, and autophagy, thereby participating in the progression of liver fibrosis. Meanwhile, traditional Chinese medicine and its active ingredients with multi-target synergistic effects have attracted wide attention. From the perspective of the interaction between organelles, this article systematically elaborates on the specific mechanism of such interactions in the progression of liver fibrosis and reviews how traditional Chinese medicine inhibits HSC activation and collagen production by regulating the function of these organelle and their interaction networks, thereby exerting an anti-liver fibrosis effect, in order to provide a theoretical basis for in-depth understanding of the pathological mechanism of liver fibrosis and the development of new traditional Chinese medicine intervention strategies.

Metabolic dysfunction-associated fatty liver disease (MAFLD) is a chronic metabolic liver disorder with complex etiologies. Different clinical phenotypes of MAFLD (such as obesity, hyperlipidemia, type 2 diabetes mellitus, the postmenopausal state, and chronic hepatitis B) have different mechanisms of action in the development and progression of MAFLD, leading to high heterogeneity in its clinical progression and prognosis. This article systematically reviews the pathogeneses and clinical features of the above five clinical phenotypes of MAFLD and elaborates on the corresponding individualized diagnosis and treatment regimens integrating traditional Chinese medicine and Western medicine, in order to provide a reference for clinical practice and improve clinical diagnosis and treatment.

Nonalcoholic fatty liver disease(NAFLD) is the most common chronic liver disease in the world. Because of its complex pathogenesis, high clinical prevalence and large population, it poses a great threat and challenge to public health in the world. Therefore, active intervention measures are needed. Currently, western medicine is effective in reducing weight, reducing liver fat content, improving glucose-lipid metabolism and insulin resistance. However, for patients with NAFLD-related fibrosis and cirrhosis, there is still a lack of sufficient histological evidence to support its benefits, and randomized controlled trials are still needed to clarify. Lifestyle intervention is an important cornerstone for the treatment of NAFLD, but there are many problems such as poor implementation and low compliance of patients, and the clinical efficacy is not ideal. Traditional Chinese medicine(TCM) has the significant advantages of multiple pathways and multiple targets. Berberine, the active ingredient of TCM, can interfere with the production of NAFLD from multiple pathways, including increasing energy consumption, weight loss, improving glucose-lipid metabolism, improving insulin resistance, anti-inflammatory, anti-oxidation, regulating intestinal flora, restoring bile acid homeostasis, anti-fibrosis and so on, which can play a positive role in the treatment of NAFLD. At the same time, it was found that the combination of BBR with Chinese and western medicines had significant advantages in promoting drug absorption, improving oral bioavailability, increasing the highest biological distribution in the liver, enhancing the overall therapeutic effect of NAFLD, and reducing adverse drug reactions, which could provide reference for clinical medication.

Objective:To analyze the relevant studies on fertility concerns intervention programs for breast cancer survivors of childbearing age, and identify the specific content, outcome indicators and intervention effects of intervention, in order to provide reference for clinical staff to implement relevant intervention.Methods:According to the research method of scope review, the studies on the fertility concerns with breast cancer patients of childbearing age in China National Knowledge Infrastructure, WanFang, VIP, China Biomedical Literature Database, CINAHL, PubMed, Cochrane Library, Web of Science etc. were searched. The search period was from database establishment to May 9, 2024. The included literature was classified and analyzed.Results:A total of 12 articles were included, 9 were randomized controlled trials, 2 were self-controlled before and after studies, and 1 was a prospective cohort study. Fertility concerns intervention programs included group fertility counseling centered on couples, fertility support based on a multidisciplinary team collaboration model, and fertility management based on "Internet + reproductive health". The duration of intervention was usually 4 or 24 weeks. The intervention had different effects on the level of fertility concerns, psychological state and marital status.Conclusions:At present, the intervention programs for fertility concerns of breast cancer survivors of childbearing age reflect the importance, professionalism, immediacy and interactivity, but China is in the initial stage, and there are still shortcomings in multidisciplinary teams, fertility referral system, and Internet platform construction. Future research should build a breast cancer fertility intervention program suitable for our country, and promote its application through the Internet.

OBJECTIVE:
To explore the clinical phenotype and genetic characteristics of a child with neurodevelopmental disorder caused by homozygous frameshift variant of the TRAPPC6B gene, and to provide reference for the diagnosis of the disease.
METHODS:
A child with neurodevelopmental disorder caused by homozygous variant of TRAPPC6B gene who was admitted to the Children's Hospital Affiliated to Zhengzhou University in March 2023 due to "inability to stand and walk independently at 1 year and 3 months old" was selected as the study object. The clinical data were collected by retrospective analysis method. Target region high-throughput sequencing was carried out on the child and parental peripheral blood samples, and candidate variant was verified by Sanger sequencing and bioinformatic analysis. The pathogenicity of variant was rated according to the Standards and Guidelines for the Interpretation of Sequence Variants released by American College of Medical Genetics and Genomics (ACMG) (hereinafter referred to as ACMG guidelines). The study has been approved by the Medical Ethics Committee of the Children's Hospital Affiliated to Zhengzhou University (Ethic No.2022-K-L025).
RESULTS:
The child was a 1-year-and-3-months-old boy whose parents were sib mating. The child presented with global developmental delay, microcephaly and short stature. MRI showed poor white matter myelination, abnormal signals of bilateral periventricular white matter and bilateral external sac, thin corpus callosum, and widening of the third ventricle. Genetic testing revealed that the TRAPPC6B gene of the child had a homozygous variant of c.240_241delAA (p.Q80Hfs*34), which was inherited from his parents. According to the ACMG guidelines, this variant was judged to be potentially pathogenic (PVS1_Strong+PM2_Supporting+PM3_Supporting), resulting in premature occurrence of terminator codons and a change in the three-dimensional structure of protein. The variant was located in the functional domain, which may directly affect the functional domain of the protein, resulting in functional domain defects.
CONCLUSION
The frameshift variation of TRAPPC6B gene c.240_241delAA (p.Q80Hfs*34) has not been reported, which may be the genetic cause of neurodevelopmental disorders in child in this study. These findings expand the variation spectrum of TRAPPC6B gene and provide basis for genetic counseling and prenatal diagnosis of this family.
