[摘 要] 目的:探讨胰岛素样生长因子2 mRNA结合蛋白3(IGF2BP3)、尿苷二磷酸-葡萄糖醛酸脱羧酶1(UXS1)在肝细胞癌(HCC)中的表达特征、预后价值及两者协同作用的分子机制。方法:整合UALCAN、cBioPortal、ENCORI、TISCH2、GDSC等公共数据库的转录组数据,对IGF2BP3和UXS1进行表达、预后评估、功能富集及药物敏感性等分析。收集GEO数据库的单细胞RNA测序(scRNA-seq)数据,分析细胞通信、单细胞代谢评分,系统解析IGF2BP3-UXS1轴在HCC中的具体作用。结果:IGF2BP3、UXS1在HCC组织中均显著高表达,且高表达患者总生存期显著缩短(均P < 0.05)。采用CRISPP技术敲除IGF2BP3或UXS1后,多种HCC细胞的增殖能力受到明显抑制。scRNA-seq分析揭示了IGF2BP3、UXS1在肝细胞等细胞类型中的广泛表达分布,前者在细胞分化晚期上调,后者则在细胞分化早、中期高表达。IGF2BP3、UXS1高表达组均显著激活了MIF通路,同时IGF2BP3的高表达削弱了成纤维细胞的相互作用,而UXS1的高表达则增强了T细胞的信号转导功能。IGF2BP3与UXS1在表达相关性中存在显著的正相关(r = 0.432,P < 0.05)。沉默IGF2BP3结合位点会导致UXS1表达水平变化(F = 0.333)。功能富集分析提示,IGF2BP3与UXS1协同调控能量代谢、蛋白质翻译等生物学过程。在IGF2BP3或UXS1高表达的细胞亚群中,发现两者与多个糖代谢相关通路存在显著关联。IGF2BP3、UXS1高表达的患者对优普色替等药物表现出显著的敏感性,还对药物那维托克等表现出显著的耐药性。结论: IGF2BP3、UXS1在HCC中高表达,两者通过调控糖代谢重编程的协同作用促进HCC恶性生物学行为。

This paper summarizes Professor LIU Shangyi's clinical experience in treating acute mastitis based on the "membrane collaterals" theory. It is considered that constraint and stagnation of the membrane collaterrals is the primary pathogenic factor, with damp, heat, phlegm, and stasis being the secondary manifestations. If untreated, the condition can progress to heat toxin injuring the membrane. In treatment, the emphasis is diffusing and unblocking membrane collaterals, unblocking breast and relieving constraint. The clinical course of the disease can be divided into three stages including the early stage with mild constraint heat, the middle stage with escalating toxic heat, and the later stage with a decline of pathogens but deficiency of healthy qi. In correspondence, self-made Tongru Formula (通乳方) for diffusing membrane and venting constraint, self-made Toumo Jiedu Formula (透膜解毒方) for unblocking membrane and relieving toxin, and Tuoli Xiaodu Powder (托里消毒散) with modifications for restoring membrane and rectifying healthy qi should be used, respectively.

According to traditional Chinese medicine (TCM) theory, impaired spleen transportation function disrupts nutrient distribution, causing metabolic accumulation of lipids that transform into pathogenic phlegm-dampness. These pathological factors disseminate through the San Jiao and obstruct meridian pathways, ultimately forming the pathogenesis described as "all disorders involve phlegm". Phlegm and dampness share common pathogenic origins but manifest distinct clinical manifestations. Dampness, as the precursor, may congeal into phlegm, while existing phlegm accumulation can further exacerbate dampness stagnation, thereby establishing a self-perpetuating pathological cycle. Modern medical research has confirmed that the essence of "phlegm-dampness" syndrome is closely associated with energy metabolism disorders, serving as a common pathological basis for metabolic syndrome, type 2 diabetes mellitus, atherosclerosis, and other major chronic diseases. As a crucial vehicle for medical experimental research, disease-syndrome combination animal models serve as an indispensable means to advance the modernization of TCM. Currently, based on classical theories such as "rich and greasy foods produce phlegm" and "physical coldness combined with cold consumption causes external pathogens to invade the skin and hair, thereby generating internal dampness", researchers primarily employ two paradigms to construct animal models of phlegm-turbidity, dampness obstruction, and phlegm-dampness syndromes: the first involves simulating TCM etiological factors (through methods like dietary irregularities, imblanace between work and rest, and combined internal-external dampness exposure), while the second combines disease with syndrome differentiation (inducing pathological changes through physical, chemical, or biological interventions). Through comprehensive evaluation incorporating macroscopic observation and microscopic index detection, model animals undergo systematic biological and pathological assessment, with further syndrome type verification achieved via the "prescription-based syndrome detection" approach. However, existing models still exhibit significant deficiencies in both the standardization of modeling methodologies and the systematization of evaluation criteria. This paper reviews the strategies for constructing "phlegm-dampness" syndrome animal models and their corresponding evaluation indices, focusing on the pathological correlations among different modeling approaches. The aim is to provide methodological guidance for research on TCM syndromes related to "phlegm-dampness" syndrome and to support the development of TCM therapies for resolving phlegm and eliminating dampness. This study not only contributes to advancing the standardization of TCM syndrome research but also provides crucial technical support for the modernization of TCM.

Objective:
To investigate the health-related quality of life and its influencing factors in elderly patients with metabolic syndrome (MS), so as to provide the evidence for improving health-related quality of life in older adults with chronic diseases.
Methods:
In 2021, elderly MS patients aged ≥60 years from four districts in Nanjing City were selected as the study subjects using a multi-stage random sampling method. Data on social demographic information, lifestyle, disease history and blood biochemical indicators were collected through questionnaire surveys, physical examination and laboratory tests. Health utility value and EuroQol Visual Analog Scale (EQ-VAS) score were assessed using the EuroQol 5-dimension 3-level questionnaire. Factors affecting health-related quality of life were identified with the Tobit regression model and multiple linear regression model.
Results:
A total of 3 378 elderly MS patients were included, with a median age of 67.00 (interquartile range, 7.00) years. There were 1 558 males (46.12%) and 1 820 females (53.88%). The median (interquartile range) of health utility value and EQ-VAS score were 1.00 (0.03) and 80.00 (15.00). Tobit regression and multiple linear regression analysis showed that gender (female, β=-0.034), education level (middle school, β=0.024; junior college and above, β=0.046), marital status (married, β=0.014), physical activity (sufficient, β=0.013), vegetable intake (meet standard, β=-0.009) and fruit intake (meet standard, β=0.016) were the influencing factors of health utility value. Residence (urban area, β=1.933) and alcohol consumption (yes, β=1.761) were influencing factors of EQ-VAS score. Age, cardiovascular and cerebrovascular diseases, malignant tumors and chronic respiratory diseases were the influencing factors of health utility value and EQ-VAS score.
Conclusion
Age, sex, marital status, residence, lifestyle and disease are mainly associatied with the health-related quality of life in elderly MS patients.

Objective To analyze the epidemiological characteristics of mumps in Guangxi from 2012 to 2024, and to provide a scientific basis for formulating prevention and control strategies. Methods Descriptive epidemiological methods were used to analyze the incidence data of mumps in Guangxi from 2012 to 2024. Results A total of 159 873 mumps cases were reported from 2012 to 2024 in Guangxi, with an average annual reported incidence of 25.41/100 000, and no death. Mumps occurred every month, with the peak incidence mainly concentrated in April to July and October to January of the next year. There were 96,118 male cases (29.43 /100 000), and 63 755 female cases (21.07 /100 000). The male to female ratio was 1.40:1, and the difference between male and female was significant (χ2=4 321.276,P<0.05). The annual incidence of mumps showed a certain periodic change, with the incidence peak and trough alternating every 4 - 5 years. The majority of patients were under 15 years old, accounting for 85.32% of the total number of cases. The patients mainly included students, preschool children and scattered children. The highest average incidence was in Nanning City with 40 231 cases (42.08/100 000), and the lowest was in Qinzhou City with 3 466 cases (8.16/100 000). From 2012 to 2024, a total of 210 mumps outbreaks with 4 483 cases were reported in Guangxi. Conclusion The incidence of mumps in Guangxi from 2012 to 2024 shows a periodic change and obvious seasonality. People under 15 years old are the key group at risk of mumps. The prevention and control of the epidemic of mumps in schools and kindergartens should be strengthened. It is suggested to carry out long-term monitoring of mumps as well as immune effect research, and continue to maintain a high vaccination rate of 2 doses of mumps-containing vaccines.

Objective:
To investigate the potential protective effect of Shexiang Tongxin dropping pills (STDP) on ischemia-reperfusion injury and its underlying mechanisms in improving endothelial cell function in coronary microvascular disease (CMVD).
Methods:
A rat model of myocardial ischemia-reperfusion injury with CMVD was established using ligation and reperfusion of the left anterior descending artery. The effect of STDP (21.6 mg/kg) on cardiac function was evaluated using echocardiography, hematoxylin-eosin staining, and Evans blue staining. The effects of STDP on the microvascular endothelial barrier were assessed based on nitric oxide production, endothelial nitric oxide synthase expression, structural variety of tight junctions (TJs), and the expression of zonula occludens-1 (ZO-1), claudin-5, occludin, and vascular endothelial (VE)-cadherin proteins. The mechanisms of STDP (50 and 100 ng/mL) were evaluated by examining the expression of sphingosine 1-phosphate receptor 2 (S1PR2), Ras Homolog family member A (RhoA), and Rho-associated coiled-coil-containing protein kinase (ROCK) proteins and the distribution of ZO-1, VE-cadherin, and F-actin proteins in an oxygen and glucose deprivation/reoxygenation model.
Results:
The administration of STDP on CMVD rat model significantly improved cardiac and microvascular endothelial cell barrier functions (all P < .05). STDP enhanced the structural integrity of coronary microvascular positioning and distribution by clarifying and completing TJs and increasing the expression of ZO-1, occludin, claudin-5, and VE-cadherin in vivo (all P < .05). The S1PR2/RhoA/ROCK pathway was inhibited by STDP in vitro, leading to the regulation of endothelial cell TJs, adhesion junctions, and cytoskeletal morphology.
Conclusion
STDP showed protective effects on cardiac impairment and microvascular endothelial barrier injury in CMVD model rats induced by myocardial ischemia-reperfusion injury through the modulation of the S1PR2/RhoA/ROCK pathway.
