Based on the modern understanding that lipid metabolism disorders mediate tumor microenvironmental imbalance in esophageal carcinoma， this paper proposes that failure of spleen and kidney warming and internal accumulation of phlegm-toxin constitute the core pathogenesis of esophageal carcinoma. Deficiency of spleen and kidney yang qi serves as the root cause， while impaired transformation and transportation of lipids and the accumulation of phlegm-toxin represent the superficial manifestations. Phlegm originates from the transformation of lipids， while toxin arises from and attaches to phlegm. Their interaction forms a sticky and persistent pathological state that runs throughout the entire disease process. The evolution of pathogenesis follows a dynamic and progressive pattern. In the early stage， failure of spleen and kidney warming and dysfunction of lipid metabolism mediate abnormalities in a lipid-enriched microenvironment； in the middle stage， lipid turbidity condenses into phlegm， and phlegm-toxin stasis promotes the formation of an inflammatory and hypercoagulable microenvironment； in the late stage， dysfunction of the sanjiao （三焦） warming function and impaired qi transformation lead to an imbalance in the hypoxic and metabolically dysfunctional microenvironment. Accordingly， a staged therapeutic approach is proposed， including warming the kidney and strengthening the spleen， transforming phlegm and resolving toxin， and warming and unblocking the sanjiao. By regulating lipid metabolism to restore tumor microenvironmental homeostasis， this approach provides a new theore-tical perspective and practical strategy for the intervention of esophageal cancer progression through traditional Chinese medicine.

Objective: To analyze the distribution and related factors of spherical equivalent(SE) anisometropia in school aged children in ethnic minority areas of Yunnan Province, so as to provide a scientific basis for the intervention and control of SE anisometropia. Methods: In October 2021,a total of 1 852 school aged children in three counties/cities(Lijiang City,Dali City,Xishuangbanna) in Yunnan Province were examined by multi stage cluster random sampling method for computer optometry visual acuity examination for non ciliary paralysis and questionnaire survey.Demographic characteristics, ocular biological parameters and SE data were obtained for SE anisometropia. Group comparisons were conducted using Mann-Whitney U test or Kruskal-Wallis H test, and Logistic regression was used to explore the related factors of anisometropia in SE. Results: The prevalence of SE anisometropia among school age children was 23.0%, and the prevalence was higher in girls (24.2%) than that in boys (21.6%). Compared with non anisometropic children, school aged children with SE anisometropia had longer axial length (AL) [24.03 (23.41, 24.76), 23.93 (23.26, 24.61) mm] and corneal curvature radius (CR) [43.42 (42.43, 44.42), 43.14 (42.23, 44.04)mm], SE[-1.75(-2.75,-1.00),-0.94(-2.63,-0.25)D], smaller spherical scope [-1.38(-2.38,-0.75),-0.75(-2.38,0)D], deeper anterior chamber depth(ACD)[3.77(3.62, 3.93), 3.72(3.55, 3.89)mm], and grater differences in AL[0.58(0.32,0.82), 0.13( 0.06 ,0.22)mm], ACD[0.05(0.02,0.08), 0.03(0.01,0.06)mm] and AL/CR[0.01(0.01,0.02), 0.01(0.00,0.01)]( Z =-22.47 to -2.41, all P <0.05). The results of Logistic regression showed that mild myopia( OR =2.74), moderate myopia( OR =3.52), and high myopia( OR =8.92) had a relatively high risk of anisometropia SE in school aged children(all P <0.05). Conclusion The prevalence of SE anisometropia in school aged children in ethnic minority areas of Yunnan Province is relatively high, and the prevalence and degree of anisometropia were closely related to myopia degree and related refractive parameters.

Based on ultra-high performance liquid chromatography-quadrupole-Exactive Orbitrap mass spectrometry(UPLC-Q-Exactive Orbitrap-MS) technology and network pharmacology, this study explored the pharmacodynamic substances and potential mechanisms of Huazhuo Sanjie Chubi Decoction in the treatment of gouty arthritis(GA). UPLC-Q-Exactive Orbitrap-MS technology was used to identify the components in Huazhuo Sanjie Chubi Decoction, and the qualitative analysis of its active ingredients was carried out, with a total of 184 active ingredients identified. A total of 897 active ingredient targets were screened through the PharmMapper database, and 491 GA-related disease targets were obtained from the OMIM, GeneCards, CTD databases. After Venn analysis, 60 intersecting targets were obtained. The component target-GA target network was constructed through the Cytoscape platform, and the STRING database was used to construct a protein-protein interaction network, with 16 core targets screened. The core targets were subjected to Gene Ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analyses, and the component-target-pathway network was constructed. It was found that the main active ingredients of the formula for the treatment of GA were phenols, flavonoids, alkaloids, and terpenoids, and the key targets were SRC, MMP3, MMP9, REN, ALB, IGF1R, PPARG, MAPK1, HPRT1, and CASP1. Through GO analysis, it was found that the treatment of GA mainly involved biological processes such as lipid response, bacterial response, and biostimulus response. KEGG analysis showed that the pathways related to the treatment of GA included lipids and atherosclerosis, neutrophil extracellular traps(NETs), IL-17, and so on. In summary, phenols, flavonoids, alkaloids, and terpenoids may be the core pharmacodynamic substances of Huazhuo Sanjie Chubi Decoction in the treatment of GA, and the pharmacodynamic mechanism may be related to SRC, MMP3, MMP9, and other targets, as well as lipids and atherosclerosis, NETs, IL-17, and other pathways.

Background/Aims: Dexamethasone (DEX) is a widely used exogenous therapeutic glucocorticoid in clinical settings. Its long-term use leads to many side effects. However, its effect on metabolic disorders in individuals on a high-fat diet (HFD) remains poorly understood. Methods: In this study, HFD-fed mice were intraperitoneally injected with DEX 2.5 mg/kg/day for 30 days. Lipid metabolism, adipocyte proliferation, and inflammation were assayed using typical approaches. Results: DEX increased the epididymal fat index and epididymal adipocyte size in HFD-fed mice. The number of epididymal adipocytes with diameters > 70 μm accounted for 0.5% of the cells in the control group, 30% of the cells in the DEX group, 19% of the cells in the HFD group, and 38% of all the cells in the D+H group. Adipocyte proliferation in the D+H group was inhibited by DEX treatment. Adipocyte enlargement in the D+H group was associated with increased the lipid accumulation but not the adipocyte proliferation. In contrast, the liver triglyceride and total cholesterol levels and their metabolism were downregulated by the same treatment, indicating the therapeutic potential of DEX for nonalcoholic fatty liver disease. Conclusions DEX synergizes with HFD to promote lipid deposition in adipose tissues. A high risk of obesity development in patients receiving HFD and DEX treatment is suggested.

OBJECTIVES: To evaluate the application value of genetic newborn screening (gNBS) in the Yunnan region. METHODS: A prospective study was conducted with a random selection of 3 001 newborns born in the Yunnan region from February to December 2021. Traditional newborn screening (tNBS) was used to test biochemical indicators, and targeted next-generation sequencing was employed to screen 159 genes related to 156 diseases. Positive-screened newborns underwent validation and confirmation tests, and confirmed cases received standardized treatment and long-term follow-up. RESULTS: Among the 3 001 newborns, 166 (5.53%) were initially positive for genetic screening, and 1 435 (47.82%) were genetic carriers. The top ten genes with the highest variation frequency were GJB2 (21.29%), DUOX2 (7.27%), HBA (6.14%), GALC (3.63%), SLC12A3 (3.33%), HBB (3.03%), G6PD (2.94%), SLC25A13 (2.90%), PAH (2.73%), and UNC13D (2.68%). Among the initially positive newborns from tNBS and gNBS, 33 (1.10%) and 47 (1.57%) cases were confirmed, respectively. A total of 48 (1.60%) cases were confirmed using gNBS+tNBS. The receiver operating characteristic curve analysis demonstrated that the areas under the curve for tNBS, gNBS, and gNBS+tNBS in diagnosing diseases were 0.866, 0.982, and 0.968, respectively (P<0.05). DeLong's test showed that the area under the curve for gNBS and gNBS+tNBS was higher than that for tNBS (P<0.05). CONCLUSIONS gNBS can expand the range of disease detection, and its combined use with tNBS can significantly shorten diagnosis time, enabling early intervention and treatment.
